What are Different Types of Liability Accounts

Basically every business manages liabilities, or things that it owes or has acquired. The comprehensive definition of liabilities states that liabilities are likely future sacrifices of economic benefits resulting from a company’s current obligations to transfer assets or provide services to other companies in the future as a result of previous transactions or events. However, referring to liabilities as debt is a much more intuitive description. In order to acquire resources and fund operations, businesses frequently seek funding from third parties. The lender might hold the option to either seize the acquiring business’ resources or make the borrower offer them to reimburse any remaining obligation.

To represent the creditor’s claim to the borrower’s capital in the event that debts are not paid, liability accounts are recorded on the right side of the borrower company’s balance sheet. Through the transfer of economic benefits in the form of money, goods, or services, these debts are paid off over time. The aat level 2 course accounting equation requires that the total amount of liabilities equal the total amount of assets and equity.

Resources = Liabilities + Value

Normal Sorts of Liabilities

There are two primary sorts of liabilities, current and non-current. A current liability is the first type, and it is expected to be paid off within one year or the operating cycle, whichever comes first. As a result, they are more commonly referred to as short-term liabilities. a non-current liability, on the other hand, has a longer duration. The borrower has over a year to pay off their debt. These debts are also referred to as long-term or fixed liabilities. The various kinds of liability accounts that fall under these two categories are outlined below.

Current Liabilities

Overdraft occurs when a company borrows money from a bank by overdrawing its account, taking out more money than the account is worth, and then paying back the difference to the bank. There is interest on the credit, and there is regularly a charge for each overdraft.
When a company purchases goods or inputs on an account and must repay them, this is called accounts payable.

Taxes Payable – for the purpose of collecting sales taxes and deductions for employees;
Any wages that the business owes to its employees but has not yet paid;

Gathered Costs – when a business or association represents costs that it will pay off at future dates;
Customer prepayments are money paid by customers in exchange for services or products from the company;
Current Portion of Long-Term Debt: a portion of debt with an overall maturity of more than a year; Interest Payable: any interest on loans that has been accrued but has not been paid as of the date on the balance sheet. portion is due within a year.

Deferred or unearned revenue is when a business sells goods or services to a customer who pays for them but never receives them. Those products and services are still owed to the customer.

A fixed-liability mortgage is a loan used to buy new property or expand an existing one;
Loans for automobiles and equipment typically involve significant upfront costs that must be paid back over time;
Notes Payable are the company’s equity or debt securities;

Deferred Tax Liabilities arise when an accounting period’s income differs from the taxable amount reported on the return;

Annuity Commitments – cash that must be represented to make future benefits installments;
Other Long-Term Debt: borrowings that have to be paid back in full in more than a year.

Contingent liability

A contingent liability is a third, less common type of liability in addition to the ones mentioned above. These debts are contingent on upcoming outcomes, or contingencies. If both of the following conditions are satisfied, a contingent liability can be established:

Although their name suggests something negative, liabilities are actually important aspects of enterprise management. The outcome is likely. The cost can be reasonably estimated. They are vital to arranging fruitful tasks and making esteem.

For instance, organizations regularly acquire cash to subsidize activities, pay for huge developments, and smooth out exchanges with different organizations. When these debts are not managed well, they become a problem, which can lead to financial decline, problems with solvency, and, in the worst cases, bankruptcy. To keep away from these issues, entrepreneurs ought to get comfortable with the sorts of liabilities and how they are assessed during the bookkeeping cycle.

Top benefits of a steel and glass Conservatory

The production of steel and glass has improved over time, laying the groundwork for the development of winter garden designs into increasingly fascinating and modern structures. The greenhouse architecture of the nineteenth and twentieth centuries was characterized from an aesthetic standpoint by a vast repertoire of shapes and decorations, influenced by the neoclassical, neo-gothic, and Moorish styles, thanks to new and increasingly particular metal bearing structures.

We quickly developed winter garden Timber windows birmingham conservatories as a result of the success of greenhouses, the desire to enjoy them throughout the year, and the pleasure of interacting with the lush green world. These structures consequently wound up turning into a fundamental part or an expansion of the house.

As a matter of fact, it was exactly the chance of having the option to partake in the outside space in spite of horrible weather patterns influencing the interest of the first class of the time.

These days, studios aren’t made exclusively in steel and glass yet additionally in different materials like wood and aluminum. However, the strengths of the metal winter gardens have already been highlighted: solidity, fire resistance, and the columns and structures’ overall lightness.

As a matter of fact, steel has numerous characteristics that meet the prerequisites of the development of a colder time of year garden. There is no question about the predominance of centers in steel and glass contrasted with different materials.

Why? Read on.

The advantages of steel conservatories

A winter garden’s metal structure provides stability and strength. Before receiving a specific powder-coating preparation treatment to prevent corrosion and for a long-lasting effect, each of the steel components goes through a complicated and elaborate cutting, welding, and assembly process.

However, what are the benefits of constructing conservatories out of steel?
Steel winter gardens are well-liked for their durability, as was mentioned at the beginning of the article. In point of fact, steel is a sturdy yet simple metal to work with, making it an excellent choice for the construction of conservatories, where strength and robustness are crucial.

For instance, a conservatory made of steel and glass would be ideal for housing a large living room with a dining room next to it because it would be able to provide the structural support that is required for spaces this size.

Conservatories made of steel are more durable and resistant

Metal is able to withstand the elements despite being exposed to weathering. Problems with maintenance and repair are few and far between with metal frame constructions because they are so strong and long-lasting.

Setting up a construction requires the readiness of the establishment and significantly longer establishments times than the get together of an iron and glass structure. It is sufficient to install metal plinths as a base for the construction of a steel conservatory without constructing a foundation, leaving the ground unaltered, if the dimensions permit it. Additionally, the bolt-fixed structure can be assembled and disassembled for repositioning elsewhere.

Because steel is a malleable material, winter gardens made of it can be folded and shaped in a variety of ways. Conservatories can be designed in any style and perfectly match any structure, regardless of its design or architecture, thanks to these features.

Aligning the principles and practice of research integrity and research fairness in global health: a mixed-methods study


WHAT IS ALREADY KNOWN ON THIS TOPIC

  • Over the past decade, the ideals of research integrity and research fairness have gained considerable momentum in global health. While both have been the subject of intense academic debate, there is little empirical data on actual practices related to integrity and fairness specific to global health.

WHAT THIS STUDY ADDS

  • Findings suggest that global health researchers mostly adhere to research integrity and research fairness principles. Some behaviours are more frequently reported (transparent reporting of studies, seeking local ethical approval) than others (engagement with affected populations, engagement with local decision-makers, adherence to Open Science), with little variation between responses from the Global North and the Global South.

  • We identified several structural, institutional and individual factors associated with these patterns, such as an inflexible donor landscape, research institutions’ investments in relationship building, guidelines and mentoring, as well as power differentials and competition between researchers.

HOW THIS STUDY MIGHT AFFECT RESEARCH, PRACTICE OR POLICY

  • This study shows there are more synergies than trade-offs between research integrity and fairness as they share similar determinants and the same goal of increasing research quality and maximising the societal benefits of research. There is ample scope to make such synergies explicit and to align both agendas in global health.

Introduction

Global health decisions are often made remotely, without consideration for the people they affect.1 Ideally, the conduct of global health research should straddle the twin ideals of research integrity and research fairness2 and should follow practices that guarantee the validity and trustworthiness of science.3 It should also aim to transcend the ‘distance’ between research teams and researched populations that currently characterises the study of global health problems. While the pursuit of integrity and fairness in global health can conflict ideologically,4 they share the same goal of increasing the societal benefits of research. Addressing these breaches of research integrity and fairness requires an understanding of the magnitude of the problem and its determinants.

Over the past decade, research integrity and research fairness have gained considerable momentum globally. Research integrity emerged in the late 2000s as a response to the reproducibility crisis in science.5 It encompasses all professional codes promoting Responsible Research Practices (RRPs), with a strong traditional focus on individual researchers’ responsibilities,6 but increasingly recognising the role of research environments in shaping collaborations3 7 and reward systems.8 9 Research integrity is closely intertwined with Open Science, which promotes full transparency of research processes to maximise reproducibility.10 Research fairness,11 on the other hand, encompasses a broad range of initiatives from the mid-2010s to promote fair and equitable research partnerships12 13 and a holistic understanding of global challenges. Research fairness initiatives aim to increase ownership of research agendas and outputs in Low-income and Middle-Income Countries (LMICs), thereby maximising the positive impact on local research systems and populations. These initiatives focus on power imbalances between actors in previously colonising and colonised nations and as such are broadly aligned with recent calls to ‘decolonise global health’.14 Research integrity and research fairness share the goal of increasing research quality and maximising the societal benefits of research by following two different paths.4 While research integrity prioritises, rewards and reinforces scientific processes in the pursuit of global and generalisable knowledge, research fairness is geared towards local information needs and favours knowledge production that reflects the ‘lived experience of people themselves’.14

Research integrity has been the subject of many scholarly debates, and recent surveys have reported the prevalence of Questionable Research practices (QRPs).15 16 QRPs are defined as ‘subtle trespasses’15 or ‘misbehaviours’17 that lie in the grey zone between fabrication, falsification and plagiarism on one side, and responsible research conduct on the other. The term includes practices such as not reporting flaws in study design or execution, selective citation to enhance one’s findings and so forth.15 It is sometimes argued that the ‘prevention paradox’ applies to research integrity—while QRPs may constitute a less severe offence compared with fabrication and falsification their frequency makes them more damaging to science.18 This is backed up by data: estimates of data fabrication or falsification from a recent study in the Netherlands were just above 4%15 while over 50% of researchers engaged frequently in at least one QRP. This is in line with a Nature study that revealed that ‘more than 50% of researchers are unable to reproduce their own work’.5 There are no data specifically for global health research, however, there is no reason to believe that it fares better than other types of research.19

Research fairness has also been the subject of academic scrutiny, with substantial evidence that the current global health research ecosystem is unfairly skewed towards institutions and scientists in High-Income Countries (HICs). A systematic review found that 28% of studies mentioned some kind of ‘discriminatory power imbalance’ between Global North and South research team members.1 Studies have shown that LMIC research agendas are led by donors in HICs,20 with research funding disproportionately allocated to HIC institutes.21 To our knowledge, there are no systematic analyses of global health research funding flows, but donor reports and tracking tools reveal that approximately 70% of funding is channelled through Global North institution.20 22–26 Studies on roles and perceptions of researchers in global health collaborations show that local researchers are often relegated as ‘glorified field workers’27 with no influence on study design28 and less likely to be in prominent author positions.29

While research integrity and fairness are both intensely researched, no studies to date have investigated research practices jointly influencing integrity and fairness in global health. Therefore, little is known about potential synergies and trade-offs. For example, are efforts to increase research integrity improving research fairness and vice versa? Or are strategies to increase one affecting researchers’ ability to improve on the other? Furthermore, we do not know whether there are fundamentally diverse ways of conducting research in different areas of the world, more specifically between those who are conducting research from ‘afar’ (eg, researchers based in the Global North conducting research in the Global South) versus those conducting research nearby (ie, Global South researchers conducting research in their settings). Furthermore, the research integrity agenda has so far been dominated by Global North actors, which could potentially lead to different levels of adherence to research integrity principles across geographies.

Limited research on both research integrity and fairness in global health means there is little data to support either debate—beyond norms or guidelines. Yet data on desired and undesired practices, barriers and facilitators, can provide evidence to develop improvement strategies and baselines to measure progress. To provide this information, we conducted a mixed-methods study to estimate the frequency and to explore the determinants of practices associated with research integrity and research fairness.

Methods

This mixed-methods research study combined an online survey (quantitative component) with online in-depth key informant interviews (qualitative component). The quantitative component estimated the frequency of research practices by measuring self-reported adherence to norms and guidelines of research integrity and fairness. The qualitative component aimed to provide context and to explore determinants, that is, barriers and facilitators for such practices. Determinants could be described at individual (concerning the researchers themselves), institutional (regarding academic institutes) and structural (the wider research landscape) levels. The qualitative research tools were based on preliminary analyses of the quantitative component (exploratory approach). In line with previous research integrity surveys, we defined QRPs as ‘misbehaviours (that) lie somewhere on a continuum between scientific fraud, bias and simple carelessness’.17 Following this logic, we defined Unfair Research Practices (URPs) as behaviours that perpetuate power imbalances, marginalisation, exploitation and inequality in the production and dissemination of knowledge. As opposed to QRPs and URPs, RRPs and Fair Research Practices (FRPs) promote positive behaviours related to research integrity and fairness respectively. This study builds on a pre-existing pilot study.30

Data collection tools

The questionnaire for the online survey can be found in the repository. This self-administered survey was developed and emailed to researchers in English. This tool lists 20 QRP/RRPs related to research integrity and 20 URP/FRPs related to research fairness, including adaptations of questions developed by the Dutch National Survey on Research Integrity (NSRI)31 that are in line with the Bridging Research Integrityamd Global Health Epidemiology (BRIDGE) criteria.4 Alignment with the NSRI was done to enable comparisons and because the NSRI questions underwent prior psychometric validation.4 15 For research fairness, we developed 20 URP/FRPs derived from the BRIDGE criteria. Like the NSRI survey we used statements in the first person, a 3-year recall period and a 7-point Likert scale to retain similar levels of content and construct validity. The Likert scale consisted of the following values: 1=never, 2=very rarely, 3=rarely, 4=occasionally, 5=frequently, 6=very frequently and 7=always. To avoid straight lining, some statements were phrased as a questionable/unfair and some as responsible/fair.

The in-depth interview schedule was based on the BRIDGE guidelines and included topics on participants’ experiences with QRPs and URPs and determinants of these practices. This schedule covered all six phases of an epidemiological study (preparation, protocol development, data collection, data management, data analysis and reporting). The interviewers navigated the conversations according to interviewees’ preferences for focusing on given study phases and exploring contributing factors. Interviewers probed interviewees for statements where quantitative findings showed the strongest differences or overall lowest or highest scores. We aimed at receiving maximum variation of phases among interviews. All interviews were conducted in English.

Study population and setting

The study population consisted of researchers currently involved in global health and working in institutes that are part of the following networks: tropED (Network for Education in International Health), INDEPTH Network, Asian Health and Demographic Surveillance System Network, Astra South Asia, African Institute of Mathematical Science, Consortium of Universities for Global Health, Humanitarian Health Ethics Network, Collaboration for Evidence Based Health Care in Africa, Trials of Excellence in Southern Africa, West African and Central African Network for TB, HIV/AIDS and Malaria, East African Consortium for Clinical Sciences, Bill & Melinda Gates Foundation Global Health Grantees, Southeast Asia One Health University Network, COVID-19 Clinical Research Coalition and the European and Developing Countries Trial Partnership. We used the algorithm in figure 1 to assess eligibility of institutions within the sample framework. ‘Relevant institutions’ included universities, non-profit non-government research/knowledge centres, government research institutes or funding institutions with a role in research development. ‘Relevant type of research’ included global health (international) or public health (national) research involving interactions with communities, patients, public or other local actors (ie, not laboratory or document based).

Algorithm to assess the eligibility of institutions.

Institutes were categorised by geographical location—Global North and Global South—to enable stratified sampling and equal geographical distribution of institutes across geographies. In the absence of an objective measurement to classify countries as Global North or South, we referred to the World Bank 2021 country income classifications32 in LMICs, upper-middle-income countries (UMICs) and HICs. More specifically, LMICs and UMICs were considered as Global South, and HICs as Global North. During quantitative data collection, participants were asked to self-identify as either Global North or Global South, with possibilities including ‘prefer not to disclose’ or ‘other’. In-depth interviews revealed that this category includes researchers raised, trained or working in different countries across north/south divide and reclassified as Global Neutral.

Sampling and sample size

For the online survey, participants were sampled using two-stage stratified cluster sampling. The sample size was calculated based on a Z-score of 1.96, a hypothesised prevalence of 50% for QRP/URPs, a precision of 10% on each side of the prevalence estimate, a design effect of 3, a 50% response rate and an additional 10% institutional attrition rate. Overall, the estimated (target) sample size per stratum was rounded up to 900. This sample was achieved by randomly selecting 30 institutes per stratum and 30 individuals per institute, in the first sampling stage. In the second stage, we compiled lists of all researchers listed on publicly available websites working in the selected institutes. Researchers were randomly selected from the compiled list and invited to participate in the online survey.

During the online survey, we captured participants’ willingness to participate in the in-depth interview. We invited three to four willing participants per strata to participate in interviews making a total of nine interviewees and we reached saturation with this sample size. Although we initially planned to select Global North and Global South researchers equally, two participants identified as ‘Global Neutral’ during the interview.

Data analyses

The frequency survey had two main outcome variables: (1) RRP score and (2) FRP score. Since the questionnaire provided statements phrased either as questionable/unfair practice or as responsible/fair, we recoded responses to align all responses on a positive scale, whereby a score of “1” for RRP or FRP denoted never engaging in that practice and a score of “7” denoted very frequent engagement. In other words, high scores for both the RRP and FRP score denoted desirable behaviours from an integrity and fairness standpoint.

We then grouped the RRP and FRP questions into behaviour domains (online supplemental table 1). RRPs questions were grouped under (1) following meticulous research process; (2) mentoring of junior researchers, (3) ensuring adequate methods; (4) aiming for transparent reporting; (5) striving for reproducibility and (6) engaging with open science. FRPs were grouped under (1) aiming for engagement of local decision-makers; (2) aiming for engagement of affected populations; (3) working in partnership with local researchers; (4) striving for fair agreements between study partners; (5) seeking local ethical approval and (6) ensuring respectful data collection.

We reported the median (and IQR) of Likert scale responses for each RRP and FRP. Average scores in each behaviour domain were derived followed by median and IQRs. This two-step process involved estimating a mean score for each behaviour domain and estimating the overall mean for each domain. Statistical differences between the Global North and Global South researchers for individual practices (RRP and FRP) were explored using the Wilcoxon rank sum test and differences across each of the 12 domains were with a Student’s t-test. We used linear regression to explore individual factors associated with RRPs and FRPs. We included the researcher’s age, gender, seniority (highest attained degree), discipline of the researcher, place of origin (Global South researcher working for Global North institutions or vice versa), years of involvement in research and role of the researcher as independent variables. We reported the results as adjusted coefficient, 95% CI and p values.

For the qualitative analyses, we used the six phases of the BRIDGE guidelines to create codes (deductive approach) and later added new codes arising from the data (inductive approach). Relevant and similar codes were merged into categories and analysed to identify themes arising from the data. We used NVivo software V.11 for data coding and analysis.

Data management

We used Survey Monkey to collect quantitative data online adhering to global data safety and protection practices like limiting identifiable researcher information and automatically deleting stored data after 13 months. Participants provided some indirect identifiers during the data collection, including geographical region of institute and level of experience, to prospectively strengthen the analysis and allow us to explore the data in different strata. These data, however, were presented carefully to prevent the identification of individual members.

Qualitative data collected were audio recorded in online meeting platforms, following informed consent and anonymised prior to storing in a password-protected online folder. The qualitative data from the interviews were transcribed using otter.ai and were checked and edited manually for all the transcripts. Personal identifiers were removed throughout the transcription and coding processes and labelled based on their identification as Global North (GN), Global South (GS) or Global Neutral (GX) researchers.

Patient and public involvement

This meta-research study is not conducted on patients but on researchers themselves. Researchers were consulted in the past with a Delphi study for the development of the BRIDGE guidelines that laid the foundations of this research. In addition, we set up a study task force including researchers from South Africa, India and the Netherlands that independently reviewed this study’s tools and methods ahead of data collection. This publication will be shared with all researchers who participated in this study.

Results

Sample description

Of the 1717 researchers contacted to participate in the survey, 145 (8.4% responded). Response rates were slightly higher for researchers in the Global South than the Global North at 9.5% (n=82) and 6.2% (n=53), respectively.

The survey participants’ country of origin exhibited a geographical distribution, with India comprising 9.0% (n=13) of respondents, followed by South Africa, Switzerland and the UK, each accounting for 5.5% (n=8). The USA constituted 4.8% (n=7) and represented a significant portion of respondents. Additionally, researchers from Nigeria (n=6), Ghana (n=5), Belgium, Germany, Zambia and Portugal, each contributing three respondents, were identified. Furthermore, Kenya, the Philippines, Uganda and Australia (n=2) were represented, while Bangladesh, Indonesia, Ivory Coast, Malaysia, Sudan and Vietnam each had one participant. While 44% (n=64) either did not respond to the question or preferred not to disclose the geographical location of their country of origin.

Professional and demographic details of survey participants can be found in table 1, though this information was provided by at most 118 (81.4%) of the researchers. Overall, our sample is slightly skewed towards Global South researchers (56.6%). The relative majority of participants were based in sub-Saharan Africa (28.3%), closely followed by those in Europe and Central Asia (22.1%).

Table 1

Professional demographics of the researchers

In terms of disciplinary background, most researchers had a biomedical background with the highest number of researchers reporting biostatistics/epidemiology as their discipline (29.0%) or biology/medicine (22.8%). Men and women are approximately equally distributed (40.7% vs 38.6%) although interestingly global south researchers were slightly more likely to be men and global north researchers slightly more likely to be women. In terms of seniority, our sample was skewed towards senior researchers with the largest group of researchers (44.8%) being established researchers with more than 10 years posteducation, followed by mid-career researchers with 3–10 years posteducation (24.8%). Most researchers had up to a PhD degree (23.4%) or were university professors (22.8%).

Research integrity and fairness behaviour domains

An analysis of frequency scores, by location (Global North vs Global South) and research behaviour domains (online supplemental table 1), shows some variation between domains but little by geographical location. These are summarised in figure 2 with further details in online supplemental table 2. Participants based in the Global South had statistically significantly higher mean scores of mentoring compared with the Global North (5.72 (SD: 1.03) vs 6.15 (1.32)) (p=0.001) as well as engagement of affected populations (4.44 (SD: 1.35) vs 5.08 (SD: 1.71) (p=0.038). We defined good mentoring as sufficiently supervising junior coworkers and giving sufficient attention to the skills or expertise to perform studies. While the engagement of affected populations comprised questions on consulting representatives of affected populations during the preparation stage of research or to develop lay dissemination products and developing dissemination products specifically for affected populations or their representatives. The highest frequency score overall was for seeking local ethical approval (online supplemental table 2) at 6.62 (SD=1.09). On the other hand, four domains stand out for having relatively lower scores around 5 (corresponding to frequently engaging in the behaviour): engagement of affected populations (consulting representatives of affected parties at preparation and dissemination, developing lay dissemination tools); engagement of local decision-makers (consulting end users at preparation phase and when developing lay dissemination material); open science (publishing articles and datasets open access) and ensuring reproducibility (preregistering study protocols, publishing valid negative studies, taking steps to correct errors in published work) (figure 2 and online supplemental table 2).

Differences in research practices between Global North and Global South researchers

Despite overall similar behaviour between Global North and Global South researchers, a detailed review of each individual practice reveals a consistent trend whereby researchers based in the Global South report more desirable behaviour, with small but significant differences across many subindicators. Median Likert scores for individual questions are presented overall and by location (Global North and Global South) in online supplemental table 3. Three main findings emerged about Global South researchers: (1) they are more likely to report having the skills and expertise essential to perform studies and sufficient supervision or mentoring of junior coworkers; (2) more likely to report consulting representatives of affected populations and end-users and (3) more likely to report having clear decision-making processes, using data sharing agreements (but less likely to report the strategies put in place to encourage data reanalysis by local researchers).

First, there are differences regarding enough attention to skills and expertise necessary and sufficient mentoring of junior coworkers, Global South researchers reported a median score of 7 (corresponding to ‘always’ as per the Likert scale) whereas Global North researchers reported a median score of 6 (very frequently). The in-depth interviews provide some context to make sense of these differences. With regard to giving sufficient attention to skills or expertise, Global North as well as Global South interviewees discussed that Global North research institutes more frequently have a leadership role, even if they lack context-specific expertise and knowledge, which may explain the slightly lower scores reported by Global North researchers. Regarding sufficient mentoring and supervision of junior coworkers, some Global South participants referred to ‘helicopter research’ projects by Global North research, as projects that are frequently insufficiently overseen by far-away supervisors. Furthermore, one Global North researcher admitted that as a junior researcher, they found themselve not receiving sufficient mentoring and supervision on decision-making processes, when they were placed in a coordinating role of a research project in the Global South, suggesting that their junior rank did not meet the level of experience necessary for the role and responsibilities.

Second, with regard to consulting end-users of research and affected populations, differences were observed when participants were asked if they consulted representatives of affected populations during the preparation stage of research. There was a statistically significant difference in the median responses between Global South researchers who reported a score of 7 (corresponding to ‘always’ as per the Likert scale) and Global North with a score of 5 (frequently) (p<0.0001) (online supplemental table 3). There was also a statistically significant difference in researchers’ responses to whether they consulted end-users of the research during the preparation stage of the research between Global South’s median score of 6 (very frequently) and Global North with a median score of 5 (frequently) (p=0.032) (online supplemental table 3). Interestingly, most qualitative data for these aspects was discussed by the researchers based in the Global South, despite their higher scores. Most participants identified the need to communicate with the local communities before, during and after the research and indicated that project/funding timelines do not provide sufficient time to do it properly: ‘…Going back to the… the community itself is. Is not…is not something that that we are good at doing.’ [GS3].

Third, when asked whether the research they were involved in had clear and fair data ownership agreements, we found statistically significant differences between the Global South, median score of 7 (always), compared with the Global North, median score of 6 (very frequently) (p=0.045) (online supplemental table 3). This was a similar difference to the one found in the question of having clearly agreed decision-making processes. Furthermore, there was a statistically significant difference in the researchers’ responses to whether strategies were put in place to encourage secondary analyses by local researchers when data was made openly available. For Global South researchers, the median score was 6 (very frequently), and for the Global North, the median score was 4 (occasionally) (p=0.037) (online supplemental table 3). These results suggest that data-sharing agreements may do little to promote reanalyses by local researchers. The few interview responses on this topic confirmed that there is an issue with the misuse or re-use of data either in the absence of agreements or beyond the original intention of the study. They also described the increased use of data-sharing agreements over time and how these agreements are only part of the solution: preventing issues with data-sharing relies more on trust and confidence between partners.

Determinants of research integrity and fairness

The study of determinants of research integrity and fairness was done both qualitatively to study structural, institutional and individual determinants of research integrity; and quantitatively (with a regression model) to estimate the effect of individual determinants (association between professional characteristics on the overall research fairness and research integrity scores).

Structural determinants

Most interviewees addressed the inflexible and inequitable donor landscape, where funding streams largely flow from Global North donors to Global North institutes, who subsequently subcontract their partners in the Global South. This funding pattern reportedly reinforces a top-down structure to the research partnership with unequal power dynamics, roles and responsibilities between Global North and Global South researchers frequently defined from the onset of a collaboration. Another structural factor mentioned by several participants was time and resource pressure, especially during the proposal and protocol development phases. This limits the fair involvement of affected populations and end-users of research as well as the ability to cocreate study tools and jointly plan fieldwork. This limited involvement can also extend to members of the research team, where pressures on the partnership leads to delegated roles in research project. The most commonly reported example is the practice of subcontracting fieldwork or data collection to a Global South team who have limited insight or influence on the prior or later stages of the research. Some interviewees further stressed that the competition between research institutes in the acquisition of work in the global health arena further intensifies the pressure on both Global North and South institutes, which can encourage URPs and QRPs.

Another structural determinant that emerged strongly from the qualitative data concerns issues around trust in research partnerships and distinct skills and qualities ascribed to researchers that are rooted in colonialism and racism.

Sometimes they think that they are white girls, boys will do better, they know better than the south, than the brown skin or black skin, (…) that maybe (we) will not do our work properly, not produce the quality,(…). So there is also a negative (attitude), without any ground, without working with somebody, they have this mindset. (…) So there’s also this colonising mentality that black people, they are lazy. They don’t do their or they don’t have the quality we can trust them. They couldn’t manage. (GS4)

The pervasiveness of neocolonial sentiments was also recognised to transcend the Global North/South divide:

I don’t think that colonisation is something that belongs to (the) North. I think it’s a concept like patriarchy. And women can be as patriarchal as possible. It doesn’t have to be men. It’s a practice, it’s a belief…. there are a lot of Southern people around (who) are also in power in the northern global hemisphere. I don’t see them behave differently. (GS4)

When it comes to dissemination and communication of results, both Global North and South participants stated that necessary but unpaid hours needed to publish in peer-reviewed journals influenced the levels of fair coauthorship. Some participants also stated that the additional responsibilities of executing projects and moving from project to project does not allow them to prioritise publications. Some interviewees also shared accounts of concerns with personal finances and livelihood putting pressure on researchers. This can lead to QRPs, such as fabricating patients and pocketing their financial reimbursement. Lastly, some responses suggest that cultural factors can also influence research practices. A specific example given by a Global South researcher concerned the practice around informally tipping gatekeepers and study participants to incentivise participation which can be viewed as questionable.

Institutional determinants: Several interviewees considered the level of buy-in and commitment to fair and robust research practices by the senior leadership in academic institutions as a crucial factor. Related to this, a lack of training and reflexivity around ethics and relationship building was often discussed:

I think people aren’t trained in relationships. (…) I mean, what if, if that could really change, those relationships could be more open, and we could more openly reflect on them with each other too, I think you could see real change. But then you have to really value like, what does it mean to create and foster a partnership? And I don’t know any curriculum that’s doing that in global health. (GN3)

While most interviewees, based in the Global North and South, acknowledged insufficient institutional commitment to addressing URPs and QRPs, some participants perceived increasing investments in training and guideline development around ethics and fairness in Global North institutes. Some interviewees recognised, however, the different institutional dynamics at northern and southern institutes, with greater overheads in the Global North affording more institutional support for safeguarding research integrity. Time constraints can also be understood as an institutional factor affecting research fairness and integrity, which interviewees addressed in relation to delayed contracting and ethics review, which can hamper the meaningful involvement and fair treatment of southern partners. Further, as previously discussed, insufficient supervision of students or junior staff also emerged as an individual determinant negatively affecting research fairness and integrity.

Individual determinants

The regression models fitted to explore the association between research practices and demographic/professional characteristics of researchers do not support strong hypotheses regarding their effect of individual determinants (online supplemental tables 4 and 5). Indeed, while some Wald tests are significant, most overall log-likelihood ratio tests are not. The only independent individual determinant which emerged from the regression analysis (beyond Global North and Global South differences discussed above) was academic rank (with more senior rank reporting more desirable behaviour) and discipline of the researcher (with biomedical sciences reporting higher scores than medicine) after adjusting for other factors. Indeed, bachelors or masters level degree was associated with a −14.0 (95% CI –27.0 to –0.74) (Wald test p=0.042) reduction in the responsible research score compared with associate professor or full professor in multivariate analyses after adjusting for location, career length, gender, geographical region the researcher and discipline of the researcher of global health. Researchers from the biomedical science discipline were associated with a −43.0 (95% CI −71.0 to –16.0) (Wald test p=0.002) reduction in the responsible research score compared with biology/medicine in the multivariate analysis after adjusting for location, years of involvement, gender, geographical region the researcher’s institute and academic rank (online supplemental table 4). When it comes to FRPs, the only independent individual determinants emerging from the regression analysis were career length and discipline. Indeed, the environmental and occupational research discipline was associated with a 18.0 (95% CI 1.1 to 35.0) (Wald test p=0.004) increase in the fair research score compared with biology/medicine in the multivariate analysis after adjusting for location, years of involvement, gender, geographical region the researcher’s institute and academic rank. Researchers preferring not to disclose their career length were associated with a −50.0 (95% CI -99 to −1.6) (Wald test p=0.046) reduction in the fair research score compared with Early Career (<3 years posteducation) in the multivariate analysis after adjusting for location, years of involvement, gender, geographical region the researcher’s institute and academic rank (online supplemental table 5). However, it is important to note that according to overall likelihood ratio tests for RRPs, the p value for the discipline of the researcher was significant (p=0.029) while for FRPs neither the academic rank nor the discipline of the researcher was statistically significant

The topic of seniority also emerged clearly from the interviews conducted, although under a different and less-flattering perspective. Most interviewees considered that seniority, in relation to researchers’ track-record of acquired work and number of publications, enables researchers to wield power over younger researchers which can result in both questionable and unfair practices. An unfair practice that was frequently discussed in interviews, as illustrated by the quote below, relates to unfair publication agreements between junior and senior-level researchers which devoid science of any potential societal value and impact.

There’s also practice those who are senior, it doesn’t matter how much they contribute, they want to be the first author. (…) Because, first of all to tell that because I am the Principal investigator, I have to be the first author of every single paper, it doesn’t matter, whoever, right? Because I brought the grant. I’ve experienced that. So the thing that I brought the grant, so I should be the first author. (…), (GS4)

Another potential reason for age discrepancies in URPs was the more recent nature of decolonising debates, resulting in junior researchers potentially being more sensitised and committed to FRP.

Related to the issue of seniority, many participants reported that concerns of career progression may incentivise Global Health researchers to engage in unfair and questionable behaviours. Interestingly, this finding was discussed mostly in relation to Global North researchers, and practices concerning fair involvement of Global South partners in the research preparation as well as dissemination and communication stage.

I really think that it’s much easier for (a)Western person to come to our settings and get something published. Maybe I can bring another example. You know, I was talking with someone from the North, who just came to Uganda for one-year research fellowship and then just chatting, I asked the motivation and she was like, well, but you can come here in one year, I can pull out easy, easy 2-3 papers, you know, and then I can start my career from there. So you see. Hey, there is definitely, there is less competition, it’s easy to maybe write up maybe in some institutions that you know it’s easier to get data because (…) they have no policy on data sharing and stuff like that. (…) They asked for the data, you gave it to them. (GS1).

While this quote describes Global North researchers taking advantage of their access to data for individual benefit, some also stressed what interviewee GX1 described as ‘laziness to go the extra mile’; that is, taking the time to cocreate and cede decision-making power on the use and sharing of data.

Several interviewees also pointed to language skills, an individual determinant that can be connected to structural factors around access to quality education as well as institutional factors such as the lack of linguistic diversity in the sector’s working language and within academic journals. Language skills reportedly affect both the role of Global South researchers acting (predominantly) as data collectors given their knowledge of local languages as well as being less involved in the write-up of study results, arguably because Global North partners possess stronger English language skills. Some participants also touched on another individual factor which affects (not) publishing results, being the researchers’ pride or fear of missing potential future funding opportunities associated with mentioning study flaws, limitations or negative findings.

Discussion

Overall, researchers reported mostly adhering to research integrity and research fairness principles with little geographical variation. Some behaviours are more frequently reported (transparent reporting of studies, seeking local ethical approval) than others (engagement with affected populations, engagement with local decision-makers, adherence to Open Science), with little variation between responses from Global North and Global South. However, there are some small yet significant differences in specific practices (individual questions of the survey) with Global South researchers generally more likely to report desirable practices, such as giving sufficient attention to skills and expertise, sufficiently mentoring their junior coworkers, consulting representatives of affected populations, consulting end-users of research, having clear decision-making processes agreed on, having clear and fair data ownership agreements and experiencing strategies in place to encourage secondary analyses.

Several structural factors were associated with these patterns, such as an inflexible donor landscape leading to time and resource pressure and competition. This was found to exacerbate tendencies to allocate unequal roles and responsibilities between Global North and Global South researchers that are rooted in pervasive neocolonial mentalities. However, institutional factors were also seen as important determinants, such as universities’ and research institutions’ investments in relationship building, efforts to develop and ensure adherence to guidelines and commitment to mentoring students or junior staff. Our regression analyses did not provide convincing evidence that individual determinants affect research practices, but interviews revealed that senior researchers at times enact power over younger researchers resulting in both questionable and unfair practices. Similarly, neocolonial superiority complexes were also found to explain unfair practices.

Overall we found that there are more synergies than trade-offs between research integrity and fairness as they share similar structural determinants (competitive landscape leading to time and resource pressure and competition), institutional determinants (investments in relationship building, efforts to develop and ensure adherence to guidelines, commitment to mentoring supervising of students or junior staff) and individual determinants (power differentials and competition between senior and junior researchers). This is clearly exemplified by the ‘helicopter research’ projects led by insufficiently supervised far-away supervisors (a classic threat to research integrity) but seen as key for career progression because they enable ‘quick and low-cost’ publication returns (a clear example of extractive research). Another example is data fabrication—the research integrity violation ‘par excellence’—which can be the result of financial constraints in unfair partnerships (either at the individual or project level) that put pressure on researchers in LMICs to fabricate patients and pocket financial reimbursements. This is in line with other studies that have also shown that integrity and fairness are not mutually exclusive goals. Indeed, the disproportionate and unfair distribution of decision-making power within research partnerships29 can weaken the design of research processes and tools, even in the task of properly soliciting informed consent from research participants.33 Given that both integrity and fairness share not only determinants leading to these practices but also a goal of increasing both research quality and the societal benefits of research, there is ample scope to make such synergies explicit and to align both agendas in international research collaborations, as has been advocated by the recently published Cape Town Statement on research integrity.2

The only trade-off that emerged between research integrity and research fairness agendas concerns Open Science and data-sharing. In general, practices related to Open Science (publishing under Open Access conditions as well as making data and programming code openly available) were found to be least frequently reported. This is not surprising for at least two reasons. First, much global health research relies on a mixture of quantitative and qualitative research methods. Yet it can be difficult to anonymise qualitative data when participants provide detailed information about their personal experiences and in such cases removing personal identifiers may not be enough to ensure anonymity. Second, there is a literature showing that Open Science practices are problematic in global health7 34 as they can exacerbate existing inequities between regions. Indeed, as argued in a recent review, open research processes can only lead to wide reuse or participation if there is strong pre-existing capacity to do so (in terms of knowledge, skills, financial resources, technological readiness and motivation). If that is not the case, Open Science risks mostly helping researchers in higher income countries get published, who did not share the ‘legwork’34 in collecting data but have access to higher analytical capacities (eg, students able/willing to do free internships, better computing power) and financial resources (institutional funds to pay article processing charges for spin-off research ideas). Our results are not clear-cut but in line with these concerns. Indeed, in addition to finding rather low adherence to Open Science practices, we also found that strategies were only occasionally put in place to encourage secondary analyses by local researchers according to Global North researchers (though interestingly Global South researchers reported that this happened frequently).

Although there are few studies looking at determinants of research integrity or fairness in global health, those that exist primarily focus on the former. In line with previous studies,15 we found some evidence that junior researchers are less likely to adhere to responsible research practice compared with senior researchers. This is expected as junior researchers are meant to grow into research and collaboration. However, this was not corroborated by the qualitative research which showed that senior levels researchers were more likely to have URPs, especially relating to unfair publication agreements. A recent qualitative study of global health research partnerships also outlined many factors affecting research integrity identified in our study, including the competitive culture of academia, the scarcity of long-term research grant funding, institutional cultures and power dynamics between junior and senior researchers, and lack of research integrity training.35 While that study primarily focused on practices linked to research integrity, they also describe unfair practices related to authorship, and the conflicts that can occur between Global North and Global South partners over fair attribution. Other studies of fairness in global health research have not sought to identify its determinants as we have but explored dynamics of international research partnerships that were reported as contributing factors in this study. The extractive nature of research conducted in the Global South by researchers from the Global North has been clearly argued in a study that linked between (research) data to gold and researchers and gold diggers.36 For example, even where global health research partnerships are ‘supposed’ to lead to ‘North to South transfers of financial and material resources’ macrolevel differences in power and resources end up being reproduced by the institutions, research teams and individuals that make up the partnerships.37 Even setting up such partnerships equitably can be complicated when northern funders set limits on indirect costs or overheads for the southern partner.38 Thus, while equity remains the aim for many global health research partnerships, a de facto reality is established with entrenched institutional arrangements, which extends to the division of roles across partners. Reports of Global South researchers ‘being relegated to tasks well below their capacity’ with ‘no opportunity to participate in priority-setting or in leadership roles’ are common.39 The main strength of our study is the scientific rigour of the study design, but limitations include our low response rate and associated biases. Indeed, we applied a robust epidemiological design for the frequency study based on two-stage random sampling of researchers clustered within institutes from a broad range of research networks worldwide. Latin American as well as Francophone and Lusophone African institutes are absent from our sample (apart from Cote D’Ivoire) due to their limited representation in the networks that contributed to the sampling frame. To the best of our knowledge, this is the first epidemiologically rigorous study on research fairness (although there are more examples in the field of research integrity). Moreover, we were able to combine the breadth of evidence from a global survey with the depth of knowledge obtained from interviews. Despite the small sample size, we were able to reach saturation and triangulate information on several important survey themes. However, our study suffered from a low response rate, with only 8.4% of researchers contacted via email filling in the survey. This is a well-known issue for research integrity surveys (the Dutch National Research Integrity Survey had a response rate of 21.2%15 while the survey of European and American researchers had a response rate of 7.2%40) and can be ascribed to time constraints, survey fatigue, lack of perceived relevance, trust and privacy concerns. Furthermore, we cannot exclude the possibility of positively biased responses since our study measured self-reported adherence to research practices that are well known to be either desirable or not desirable. On a more subtle level, there is also the possibility of an ‘intention-action gap’: no one is against fairness and integrity, but it often takes courage and deliberate actions to consistently act on one’s principles. Lastly, especially, considering that the response rate was different between Global North (6.2%) and Global South (9.5%), it is possible that each stratum represents a different subset of researchers, meaning the differences in scores we found between the two groups may reflect differences between these subgroups rather than ‘population-level’ differences (differential bias).

There are also some limitations pertaining to the survey tool. First, we did not determine the prevalence of research fairness and integrity, as initially intended per protocol, due to the measurement scales used. Indeed, survey questions measured the frequency of researchers’ involvement in specific practices (never, very rarely, rarely, occasionally, frequently, very frequently and always), rather than binary responses (yes, no). With hindsight, we did not feel comfortable collapsing the frequency variables into two categories as this would mean substantial data loss. As a second limitation related to our tool, some variables are more likely to generate valid responses as they incorporate specific and verifiable details about desired behaviours (eg, whether end users were consulted for dissemination products or whether researchers made material accessible on Open Science platforms). Conversely, other questions were based on subjective judgements (eg, allocation of authorship as ‘fair’ or mentorship as ‘insufficient’).

Our study has several implications for practice. Taking individual accountability as a starting point, our findings underline the importance of regular training, coaching and mentoring for global health researchers, for both junior and senior staff, ensuring exposure to up-to-date practices related to research integrity that also address issues of biases and privileges. For strengthened institutional commitment, academic institutions could prioritise investments in training as well as guideline development and adherence to ethical and FRPs. Next to the individual and institutional determinants, funding policies and inequities in the funding landscape need to be addressed at scale, as flexible and equitable practices can hopefully drive more equal power dynamics between Global North and Global South researchers and instil good practices in global health research. Overall, more scientific research on this topic will be key to taking an evidence-informed approach to tackling research fairness and integrity, for instance, providing qualitative insights to document and learn from good practices for counteracting the individual, institutional and structural determinants affecting research fairness and integrity.

Conclusion

To the best of our knowledge, this is the first study providing empirical evidence using rigorous research methods to study research fairness and integrity in global health. Our study suggests that global health researchers mostly adhere to research integrity and research fairness principles (with little geographical variation) but structural, institutional and individual factors are a barrier to following ‘ideal’ practices. Our study shows there is ample scope to align research integrity and research fairness agendas in global health, as only science that is conducted with fairness can be considered responsible and conducted with integrity. This is underscored by the fact that there are more synergies than trade-offs between research integrity and research fairness as they share similar determinants. These include structural factors, such as inflexible donor landscapes and neocolonial mentalities, and unequal roles and responsibilities between Global North and Global South researchers. In practice, our study emphasises the need for institutional and structural initiatives to promote research integrity that also address issues of biases and privileges, foster equal partnerships and address funding inequities, to promote good practices in global health research.

Punjab inmates granted relief



RAWALPINDI:

President Asif Ali Zardari and Punjab Chief Minister Maryam Nawaz Sharif on Sunday have granted relief to the prisoners in the province’s jails keeping in view the holy month of Ramazan, releasing 28 of them while reducing the sentences of others by 90 days.

The officials announced that 2,367 inmates across the province benefited from the reduction in their sentences.

However, they added that the prisoners involved in cases of drugs, adultery, robbery, kidnapping, rebellion and espionage would not receive this concession.

Similarly, this reduction in punishment has not been applied to the prisoners involved in financial embezzlement and damage to the national exchequer.

It applies to the male inmates who are 65 years of age or older and served one-third of their sentence as well as the female prisoners who are 60 years of age or older and served one-third of their jail time.

The concession also applies to the female prisoners who are accompanied by children as well as juveniles, who are below the age of 18 and served one-third of their sentence.

According to the officials, nine inmates were released from six prisons across the Rawalpindi region – six from Adiala Jail, two from Jhelum and one from Gujrat.

Besides, 642 prisoners in all the six jails of Rawalpindi region – Adiala, Gujrat, Attock, Jhelum, Mandi Bahauddin, and Chakwal – received the benefit of the special amnesty and their sentences were reduced.

Punjab IG Prisons Mian Farooq Nazir said the prisoners confined in the jails of the province and their families expressed their happiness on the announcement of the reduction of the sentences.

He added that they expressed their gratitude to the president, premier and Punjab chief minister for this move.

Earlier this month, the federal government, with the approval of PM Shehbaz, announced a significant sentence reduction for prisoners across the country.

According to a notification, the government has given a two-year remission to convicted prisoners in their jail terms.

It is customary to grant relief to prisoners during the holy month of Ramazan.

Last year, the then president Dr Arif Alvi announced a 90-day reduction in the sentences of prisoners on the occasion of Eidul Fitr when the holy month concluded.

The number of inmates who benefited from the president’s special amnesty stood at 2,610. A total of 39 prisoners were released from Rawalpindi’s Adiala Jail while 415 had their sentences reduced.

According to a statement from the President’s House, Alvi approved the reduction on basis of Article 45 of the Constitution.

Article 45 mandates that the president holds the “power to grant pardon, reprieve and respite, and to remit, suspend or commute any sentence passed by any court, tribunal or other authority”.

It Is Possible to ‘Poison’ the Data to Compromise AI Chatbots With Little Effort


According to researchers, individuals could potentially disrupt the accuracy of AI chatbots by intentionally contaminating the datasets upon which these systems rely, all for a minimal cost.

As it stands, AI chatbots already exhibit biases and deficiencies attributable to the flawed data on which they are trained. The researchers’ investigation described on Business Insider revealed that malevolent actors could deliberately introduce “poisoned” data into these datasets, with some methods requiring little technical expertise and being relatively inexpensive.

A recent study conducted by AI researchers unveiled that, with as little as $60, individuals could manipulate the datasets essential for training generative AI tools akin to ChatGPT, which are crucial for providing precise responses.

These AI systems, whether chatbots or image generators, leverage vast amounts of data extracted from the expansive digital realm of the internet to generate sophisticated responses and images.

Florian Tramèr, an associate professor of computer science at ETH Zurich, highlighted the effectiveness of this approach in empowering chatbots. However, he also underscored the inherent risk associated with training AI tools on potentially inaccurate data.

This reliance on potentially flawed data sources contributes to the prevalence of biases and inaccuracies in AI chatbots. Given the abundance of misinformation on the internet, these systems are susceptible to incorporating erroneous information into their responses, further undermining their reliability and trustworthiness.

Through their investigation, researchers discovered that even a “low-resourced attacker,” armed with modest financial resources and sufficient technical expertise, could manipulate a relatively small portion of data to substantially influence the behavior of a large language model, causing it to produce inaccurate responses.

Examining two distinct attack methods, Tramèr and his colleagues explored the potential of poisoning data through the acquisition of expired domains and manipulation of Wikipedia content.

For instance, one avenue for hackers to poison the data involves purchasing expired domains, which can be obtained for as little as $10 annually for each URL, and then disseminating any desired information on these websites.

According to Tramèr’s paper, an attacker could effectively control and contaminate at least 0.01% of a dataset by investing as little as $60 in purchasing domains. This equates to potentially influencing tens of thousands of images within the dataset.

The team also explored an alternative attack strategy, focusing on the manipulation of data within Wikipedia. Given that Wikipedia serves as a “crucial component of the training datasets” for language models, Tramèr emphasized its significance in this context.

According to the author, Wikipedia prohibits direct scraping of its content, instead offering periodic “snapshots” of its pages for download. These snapshots are captured at regular intervals, as publicly advertised on Wikipedia’s website, ensuring predictability in their availability.

Tramèr’s team outlined a relatively straightforward attack approach involving strategically timed edits to Wikipedia pages. Exploiting the predictable nature of Wikipedia’s snapshot intervals, a malicious actor could execute edits just before moderators have an opportunity to revert the changes and before the platform generates new snapshots.

This method allows for the surreptitious insertion of manipulated information into Wikipedia pages, potentially influencing the content used to train language models without raising immediate suspicion.

Tramèr suggests hat at least 5% of edits orchestrated by an attacker could successfully infiltrate the system. However, the success rate of such attacks would likely exceed 5%, he said.

Following their analysis, Tramèr’s team shared their findings with Wikipedia and proposed measures to enhance security, such as introducing randomness into the timing of webpage snapshots, mitigating the predictability exploited by potential attackers.

African polyvalent antivenom can maintain pharmacological stability and ability to neutralise murine venom lethality for decades post-expiry: evidence for increasing antivenom shelf life to aid in alleviating chronic shortages


Introduction

Snakebite envenoming, a WHO-recognised neglected tropical disease,1 is thought to cause approximately 81 000–138 000 deaths each year while permanently disabling a further 400 000 people.2 The victims of snakebite envenoming are overwhelmingly the poorest populations living in some of the most resource poor regions of the world.3 As it stands, the only established therapy for snakebite envenoming is antivenom, a polyclonal mixture of antitoxin antibodies refined from the sera of venom of hyperimmunised horses or sheep.

Antivenoms, like all therapeutics, have a defined shelf life. The WHO definition of shelf life is ‘the period of time, from the date of manufacture, that a product is expected to remain within its approved product specification while handled and stored under defined conditions’.4 For antivenoms, which are biologics, this period typically ranges from 2 to 5 years depending on the specific product, and is validated by testing the retention of key pharmacological, physicochemical, immunochemical and microbiological properties during the specified storage period. Once an antivenom has expired, it is outside the window of stability testing undertaken by the manufacturer, and thus the safety and effectiveness of the product become uncertain.

There have been critical shortages in antivenom supply for several decades.5–7 The shortages are a global phenomenon, but it is the regions in greatest need and most under-resourced that suffer the most acute shortages.6 8 Sub-Saharan Africa is the most notable example of this, with several antivenom market failures and frequent product stockouts, leading to extremely limited to no antivenom provision in large swathes of the continent.8–10 However, despite the shortfall in overall doses available, substantial quantities (up to 50% in one reported locale) of antivenom actually exceed their expiry dates and are subsequently discarded.11–13 The cause of this waste of critically precious antivenom is mainly due to difficulties in the national and regional antivenom inventory management, due to a lack of research and information around national requirements, weak infrastructure and financial inaccessibility, issues which are being actively addressed by various stakeholders.14–16

Considering the global crisis in antivenom supply, the loss of antivenom due to expiry has driven investigation into whether expired antivenoms retain clinical efficacy, with the rationale that they could be used in emergency situations when in-date antivenom is unavailable. It is widely recognised in academic settings that antivenoms can retain their efficacy for many years after their expiration, with several recent studies demonstrating retained antivenom preclinical efficacy, similar to that of non-expired antivenom, up to two decades post-expiry.17–20 Furthermore, there is clinical precedent for the use of expired antivenom in certain situations. For example, the US Food and Drug Administration (FDA) approved the use of expired North American coral snake antivenom after it was discontinued by its manufacturer Wyeth in 2006.21 In emergency cases, the use of ‘recently’ expired antivenom is recommended by the WHO if no other option is available.22 This advice seems to be reflected in practice, with reported cases of expired antivenoms being used in several countries, perhaps routinely, when in-date antivenoms were not available, with reported positive outcomes.23 24 The most extensive report detailing the use of expired antivenom was a clinical study of 31 patients suffering from systemic effects of envenoming in the Lao People’s Democratic Republic.25 The patients in this study received antivenom which was beyond expiry by 1–6 years, as a result of the unavailability of in-date antivenom within the country at the time.25

In the studies to date, there has been limited evaluation of the neutralising capacity of expired antivenom products for sub-Saharan Africa, arguably the region with the greatest antivenom supply crisis, with just a single study identified.19 South African Institute for Medical Research (SAIMR) polyvalent, manufactured by South African Vaccine Producers (SAVP), is currently the only polyvalent antivenom produced within sub-Saharan Africa15 and throughout its 50-year history, it has enjoyed a good reputation of clinical efficacy, despite limited published evidence to support this.26 Here, we present a preclinical analysis of the venom neutralising characteristics of expired SAIMR polyvalent antivenom, using eight expired batches going back to 1991 and using several of the most medically important venoms from the region. We also report on immunochemical analyses of product stability of these batches, using industry standard quality control assessments. Our findings demonstrate that SAIMR polyvalent can retain preclinical efficacy and maintain acceptable product stability up to 25 years after its stated expiry date.

Methods

Additional detailed descriptions of all of the materials and methods used in this study are provided in the online supplemental methods.

Antivenoms

For this study, we used the SAVP equine F(ab’)2 polyvalent antivenom, ‘SAIMR polyvalent antivenom’. SAIMR polyvalent is manufactured from horses that have been hyperimmunised with the venoms of Bitis arietans, B. gabonica, Hemachatus haemachatus, Dendroaspis angusticeps, D. jamesoni, D. polylepis, Naja nivea, N. melanaluca and N. mossambica. According to the product insert, SAIMR polyvalent antivenom is indicated as ‘effective against the venoms of the rinkhals, mambas, and all the cobras and vipers likely to cause life-threatening envenoming in Africa’. All SAIMR polyvalent antivenom used in this study was donated by the UK Health Security Agency (or its predecessors) shortly after its expiry date. Antivenoms were stored long term, unopened in their original sealed glass ampules, at 4°C. Eight batches of antivenom were used with the following expiry dates (month/year) and lot numbers: 08/1991 (lot A706 S1), 08/1994 (lot D04446), 07/1997 (lot G03146), 11/2000 (lot J06646), 09/2001 (lot K04846), 09/2012 (lot X02646), 07/2015 (lot BB01446), 11/2017 (lot BF00546). Transport of two vials of each batch of antivenom from Liverpool School of Tropical Medicine (LSTM) to Instituto Clodomiro Picado (ICP) was through a specialist courier service (Biocair) with uninterrupted refrigerated conditions (2–8°C) throughout. All vials were used immediately after opening. Prior to being opened, each ampoule was inspected for visual differences in its content. This included noting the colour and if there were any visible particulates of precipitates in the liquid. Due to limited quantity of antivenom of each batch available for analysis, all results below are representative of technical replicates (from single vials) only.

Venoms

LSTM venoms: venoms used in ELISAs and in vitro snake venom metalloproteinase (SVMP) and phospholipase A2 (PLA2) assays were obtained from wild-caught specimens maintained in, or historical venom samples stored in, the Herpetarium of the LSTM. Following collection, venoms were immediately frozen and lyophilised to be stored as a powder at 4°C. Venoms were reconstituted in phosphate-buffered saline (25 mM sodium phosphate, 0.15 M sodium chloride (NaCl), pH 7.4) and stored at a concentration of 1 mg/mL at −20°C, unless stated otherwise. Venoms were only freeze-thawed once prior to use. Venoms used were pooled from multiple extractions of the following species: B. arietans (origin: Kenya), D. polylepis (Tanzania), N. haje (Uganda), N. nigricollis (Tanzania) and H. haemachatus (South Africa).

ICP venoms: venoms of adult specimens of B. arietans (unspecified origin, batch #322.061), D. polylepis (unspecified origin, batch #416.031) and N. nigricollis (unspecified origin, batch #616.031) were purchased from Latoxan (Portes-dès Valence, France). After collection, venoms were stabilised by lyophilisation and stored at −40°C. Solutions of venoms were prepared in 0.9% NaCl injection USP, immediately before use.

Nephelometric turbidity

Turbidity of antivenoms was measured at ICP in 2023. Nephelometric turbidity of antivenoms, expressed as nephelometric turbidity units (NTUs), was assessed as per US Pharmacopeia specifications.27 Briefly, samples of antivenoms were placed in reading cells and analysed in a LaMotte 2020 Turbidimeter (Chestertown, Maryland, USA) through comparing the intensity of light scattered by the sample with the intensity of the light scattered by a reference solution. Assays were performed in triplicate and results expressed as mean±SD.

SVMP assay

The SVMP assay was performed at LSTM in 2022 as previously described.28 29 Briefly, 1 µg of venom in a 1 µL volume was added to each well, followed by 10 µL of antivenom diluted in assay buffer (150 mM NaCl, 50 mM Tris pH 7.5). Antivenom dilutions of 1 in 4, 1 in 8 and 1 in 16 were used. The negative control was assay buffer alone. Each condition was performed in quadruplicate on a 384-well plate (Greiner Bio-One). The plates were briefly spun at 2500 rpm and then incubated for 25 min at 37°C, and for a further 5 min at room temperature. 90 μL of a quenched fluorogenic substrate (ES010, R&D Biosystems, supplied as a 6.2 mM stock) was then added to each well using a Multidrop Combi (Thermo-Scientific), and reactions monitored using a CLARIOstar Plus plate reader (BMG Labtech) at 420 nm for 75 min (10 flashes/well, 100 cycles) at an excitation wavelength of 320 nm and emission wavelength of 405 nm. The measurements at 52 min were chosen as the endpoint as all fluorescence curves had plateaued by this time point. Raw data were recorded in MARS data analysis software (BMG Labtech) prior to export and analysis in GraphPad Prism V.9. Results were then expressed as a percentage of the venom-only SVMP activity.

PLA2 assay

The PLA2 assay was performed at LSTM in 2022. The antivenoms were tested using the commercial Abcam sPLA2 assay (Abcam) optimised for high-throughput screening.30 The final reaction consisted of 9 µL each of the antivenoms (n=8) against 1 µL of each snake venom plated out into a 384-well plate (Grenier Bio). For H. haemachatus and N. nigricollis, stock solutions of 10 mg/mL were diluted 1 in 2000, resulting in 5 ng of venom per reaction. Following incubation of the venom and antivenoms for 30 min at 37°C protected from light, the plate was acclimatised for 5 min to room temperature. 5 µL of a stock of 4 mM 5,5′-Dithiobis(2-nitrobenzoic acid) (DNTB) in distilled water was added to each well of the venom+antivenom plate. The substrate 1 mM stock was prepared by resuspending in 1X assay buffer (diluted from the 10X stock in MilliQ water: 25 mM Tris-hydrogen chloride, pH 7.5, 10 mM calcium chloride, 100 mM potassium chloride, 0.3 mM Triton X-100). The addition of 30 µL of the substrate solution per well resulted in a final reaction concentration of 0.89 mM. The addition of venom, DTNB and substrate was done using a VIAFLO384 liquid handler (Integra). Following the addition of the substrate, the plates were immediately read kinetically on a CLARIOstar plate reader at 405 nm for 15 min (settings for a full 384-well plate were 11 flashes, 161 s cycle time). Raw data were recorded in MARS data analysis software prior to export and analysis in GraphPad Prism V.9. Results were then expressed as a percentage of the venom-only PLA2 activity.

In vivo neutralisation of venom-induced lethality

Sample size determination

We used the WHO-recommended essential in vivo preclinical assay to evaluate the ability of expired antivenoms to neutralise venom-induced lethality.31 This assay stipulates minimum numbers of animals required per assay to gain statistical significance and normal data distribution via Probit analysis of the median effective dose (ED50).32 This requires data from five experimental groups (consisting of five experimental units, that is, five mice), which receive a fixed dose of venom with a variable dose of antivenom. The groups are required to have one group with all survivors, one with all deaths and three groups with some survivors and some deaths. Therefore, five experimental groups are required for each ED50 assay. To determine the in vivo efficacy of each of the eight antivenoms versus three medically important venoms requires 24 assays (600 mice).

Animal maintenance

CD1 mice weighing 20–22 g, of both sexes, were obtained from the Bioterium of ICP. Mice were housed by sex in randomly allocated groups of five in Techniplast Eurostandard Type II 1264C cages (L25.0×W40.0×H14.0 cm) and maintained at 18–24°C, 60–65% relative humidity and 12:12 light-dark cycle, with food and water available ad libitum.

Neutralisation of lethality assessment

All experiments used mixed genders, and experimenters were unblinded to the test articles. Mice were pretreated with the analgesic tramadol, administered subcutaneously, at a dose of 50 mg/kg,33 15 min prior to administration of venom challenge. Mice were then injected intravenously with mixtures containing a challenge dose of venom dissolved in sterile 0.9% NaCl USP injection solution and variable dilutions of antivenom, which were premixed and incubated at 37°C for 30 min (volume of injection was 0.2 mL).34 Challenge doses were three times the previously determined median lethal dose (LD50) for the venoms of N. nigricollis (3× LD50=55.2 µg/mouse)35 and D. polylepis (3× LD50=1.14 µg/mouse)36 and five times for the venom of B. arietans (5× LD50=110 µg/mouse).37 The rationale for using 3× LD50 challenge doses for N. nigricollis and D. polylepis, rather than the conventional 5× LD50, was a refinement due to experience with these particular venoms demonstrating the use of 5× LD50 resulted in poor resolution of dose groups outcomes. The number of resulting deaths was recorded at 6 hours.38 The ED50 and the corresponding 95% CIs were calculated by Probit analysis.32 In line with recent WHO recommendations to report in vivo antivenom efficacy outcomes using the potency metric39 (the amount of venom completely neutralised per millilitre of antivenom (mg/mL), resulting in 100% survival of test animals40), calculated ED50 values were used to determine potency using the following equation: p=n–1 LD50/ED50, where n=the number of LD50 in the challenge dose.

Results

Total protein concentration

Total protein concentration of the eight antivenoms was determined by Biuret assay and ultraviolet/visible (UV/VIS) spectrometry. Concentrations measured by the two methods were consistent overall, although the OD280 nm measurements typically reported lower concentrations than Biuret, with no trend in protein concentration over time apparent (figure 1A). Total protein concentration ranged from a low of 121 mg/mL (1994) to 157 mg/mL (2000) by Biuret (mean=142 mg/mL, SD=11 mg/mL) or 121 mg/mL (1994) to 146 mg/mL (2000) by UV/VIS spectrometry (mean=129 mg/mL, SD=9 mg/mL).

Turbidity

Visual inspection of the eight unopened antivenom vials revealed the oldest vial (1991) appeared cloudy with fine particulate matter, while the 1994 expiry antivenom appeared to have larger particulate matter but were transparent and pale yellow in colour. The remaining six antivenoms were transparent and pale yellow in colour. Nephelometric turbidity analysis reflected this, with elevated values for the oldest vials from 1991 and 1994, but acceptable levels of turbidity (<50 NTUs) for the remaining eight vials despite the time lapsed after their expiry (figure 1B).

Protein profiles

SDS-PAGE profiles of all antivenoms and GFC of four antivenoms demonstrated that >90% of the antivenom protein content corresponds to F(ab’)2 immunoglobulin fragments (ie, the active ingredients) (figure 1C). Overall, results did not demonstrate any substantive evidence of immunochemical degradation over time. Additional bands and peaks not corresponding to F(ab’)2 fragments were visible in both SDS-PAGE and GFC. Mass spectrometry identification of these additional bands reveals they are the common serum proteins alpha-1-antitrypsin and albumin. GFC also revealed an additional peak at 214 nm but not at 280 nm, indicating that it is not proteinaceous in nature (online supplemental figure 1).

ELISA and immunoblotting

Next, we examined the ability of antivenoms to recognise, via ELISA, five key African venoms; B. arietans, H. haemachatus, D. polylepis, N. haje and N. nigricollis. All expired antivenoms were able to recognise the five venoms (figure 2 and online supplemental figure 2), with examination of the absorbance at OD405 nm at a dilution of 1 in 1250, representing a dilution mid-titration curve, proving to be consistent over time (figure 2A). Immunoblotting against the same venoms suggested that there was an overall decrease in recognition of venoms by all antivenoms which expired from 1991 to 2001, as compared with antivenoms which expired in 2012, 2015 and 2017 (online supplemental figure 3).

Antivenom in vitro neutralising capacity

We subsequently investigated the ability of the expired antivenoms to neutralise toxin-specific activity in biochemical functional assays, specifically PLA2 activity (in H. haemachatus and N. nigricollis venoms) and SVMP activity (in B. arietans venom).

The SVMP activity of B. arietans venom was inhibited by all antivenoms to varying extent, with the 2012 expiry antivenom having the most potent SVMP-inhibiting activity (77.8%), while the 1994 batch possessed the lowest level of SVMP inhibition (38.0%) (figure 2B). There is a gradual reduction in B. arietans SVMP-inhibiting capability in ageing antivenoms from 2017 to 1994. However, the oldest antivenom (1991 expiry) has a greater inhibiting capability than the majority of antivenoms, with the exception of the 2012 and 2015 expiry.

The functional PLA2 activity of both H. haemachatus and N. nigricollis was inhibited by all antivenoms to varying extent (55.8–73.7% for H. haemachatus and 49.7–86.2% for N. nigricollis) (figure 2C,D). However, the capability of individual expired antivenoms in inhibiting either H. haemachatus or N. nigricollis PLA2 activity was not consistent across the two venoms. The PLA2-inhibiting capacity of the antivenoms versus H. haemachatus venom steadily reduced as the antivenoms aged (figure 2C), while antivenoms which expired in or before 2000 appeared substantially more capable of inhibiting N. nigricollis PLA2 activity than the more recently expired antivenoms (figure 2D).

Antivenom in vivo neutralising capacity

With the demonstration that expired antivenoms retained in vitro venom toxin neutralising capability, despite substantial time passing since expiry, we proceeded to determine the murine in vivo ED50 and subsequently the potency, of each expired antivenom. Using the WHO-recommended essential in vivo preclinical assay to measure antivenom neutralisation of venom-induced lethality,31 we assayed three medically important venoms (B. arietans, D. polylepis and N. nigricollis) whose envenoming is indicated for treatment by SAIMR polyvalent. Results demonstrate all antivenoms retained their ability to neutralise the systemic lethal effects of each venom (figure 3 and online supplemental table 1). The mean potency values for B. arietans were variable, with some batches having distinct lower (1991 and 1997) or higher (2012 and 2015) potency, with the remainder having potency broadly spread in between (figure 3A). Overall, while significant differences in potency were notable between some batches, there was no correlation with the B. arietans venom neutralising ability with age or protein content. The majority of mean potency values of the expired antivenoms versus N. nigricollis and D. polylepis venoms were substantially lower than those versus B. arietans venom, in line with the well-described weaker capability of antivenoms in neutralising elapid venoms versus that of viper venoms (figure 3).41 The majority of expired antivenoms had potency values in the range of 0.6–1 mg/mL with substantially overlapping CIs against D. polylepis venom, while 2012 and 2017 expiry had notably greater potency (1.6 mg/mL) (figure 3B). As with the expired antivenom potency versus B. arietans venom, while significant differences in potency were notable between individual batches, overall, there was no correlation with D. polylepis venom neutralising ability with either age of the expired antivenom or its protein content. Expired antivenom potency versus N. nigricollis venom demonstrated remarkable consistency over time, with mean potency in the range of 0.6–1.1 mg/mL with broadly overlapping CIs, with no correlation with time of antivenom expiry or protein content (figure 3C).

Discussion

In this study, we examined the immunochemical and preclinical neutralising efficacy of eight batches of expired SAIMR polyvalent antivenom, ranging from 6 to 32 years post-expiry, which had been kept in long-term refrigerated conditions, with the objective of inferring their potential suitability for use when alternatives are unavailable and to explore if existing expiry dates could be extended. The key finding of this study is that SAIMR polyvalent can retain the in vivo ability to neutralise murine venom-induced lethality for over 30 years; however, physical stability is limited to a shorter period of up to 25 years.

A major consideration for clinicians using antivenom is its visual appearance, with most clinicians unlikely to administer cloudy antivenoms for fear of loss of activity or increased likelihood of adverse reaction.42 In terms of physical stability, only the oldest antivenoms, which expired in 1991 and 1994, were visibly cloudy, with levels of turbidity in excess of permissible quality control levels. The turbidity is assumed to be aggregation of F(ab’)2, which does not represent a loss in neutralising capacity in some of the tests presented here, likely due to the majority of F(ab’)2 present in antivenom not being clinically relevant for envenoming,43 but is enough to increase turbidity substantially. Antivenom total protein concentration broadly remained stable over time, and SDS-PAGE analysis demonstrated comparable levels of F(ab’)2 fragments (figure 1C). However, minor differences in protein profiles were notable, indicating various levels of impurities, which we consider to be a result of normal manufacturing variability as opposed to deterioration in product.

Prior to in vivo assays, all antivenom batches were examined using in vitro immunological and biochemical assays to assess their ability to recognise and neutralise venom toxins. ELISA and immunoblots demonstrated all expired batches were able to recognise venoms, with no substantial differences in recognition based on antivenom expiry. Biochemical in vitro assays demonstrated that all antivenoms retained the ability to partially neutralise SVMP and PLA2-specific activity. Apparent decreases in SVMP and PLA2 neutralising activity for B. arietans and H. haemachatus were noted, with older expiring antivenoms inhibiting less toxin activity compared with antivenoms expiring more recently, although this trend was not apparent for N. nigricollis PLA2 activity. It is important to note that while these assays are a valuable indicator of whether an antivenom may or may not be suitable for use in vivo, thus preventing the use of mice in experiments likely to fail, they are not capable of predicting actual performance in vivo.

The results of the ED50 assay for determining the potency of each antivenom’s ability to neutralise the lethal effects of D. polylepis, N. nigricollis and B. arietans venom demonstrated all expired antivenoms retained preclinical efficacy, with no evidence of degradation of capability over time since expiry. The ED50 and potency values of the antivenoms versus D. polylepis and N. nigricollis are highly similar to that of previously reported values for these venoms,44–47 whereas the values for B. arietans are all within the range (higher end) of values previously reported.44 46–48 Importantly, the potency values for B. arietans and D. polylepis are highly similar to that established for a non-expired batch of SAIMR polyvalent (Batch BL01646, expiry May 2023) tested in 2021 versus B. arietans and D. polylepis venom from eSwatini (p=20.3 mg/mL and 1.8 mg/mL, respectively),44 suggesting that the in vivo potency of the expired antivenom batches is comparable with that of non-expired batches.

As described, many studies have demonstrated retained efficacy of expired antivenoms,17–19 and it is important to consider whether existing antivenom stocks could be used more efficiently,16 particularly given the lack of access to these products in low and middle-income settings.49–51 Reports suggest that clinicians are already using expired antivenom products due to lack of availability of in-date products,25 and the South-East Asia regional office WHO guidelines for managing snakebite endorse this in certain circumstances: ‘in patients with severe envenoming, recently expired antivenoms may be used if there is no alternative’.22 However, we must emphasise that while we and others have demonstrated retained preclinical efficacy of expired antivenoms in mouse models, the clinical efficacy and safety of these antivenoms cannot be confirmed from these assays. Expired antivenoms which are cloudy or have precipitates must not be administered due to the likely high risk of adverse reactions resulting from aggregates.52 The legal implications of prescribing expired antivenom must be emphasised, as the prescribing clinician may subsequently become liable for any adverse events suffered by the patient following administration of an expired antivenom and would need to counsel the patient on the potential risks.

Currently available antivenoms, particularly those marketed in Asia and Africa, are of varying quality and have often been approved by regulators and provisioned by health services, despite a lack of preclinical or clinical efficacy data.26 41 46 50 This lack of regulation has been disastrous, with evidence suggesting that poor-quality products have caused harm to patients.53 54 Some of the methods used in the present study are similar to those applied by the WHO antivenom risk–benefit assessment, which endeavours to exclude poor-quality products from the market. This programme includes a review of the product dossier, laboratory analysis (according to WHO standards for biological products)31 and manufacturing site inspection (to ensure adherence to Good Manufacturing Practices). Thus, it may be feasible for the WHO antivenom risk–benefit assessment to be extended to evaluate the quality and preclinical efficacy of expired products, which could enable manufacturers of good-quality antivenoms to extend the expiry date, or could provide regulators and clinicians with assurance that certain products can be administered for a defined period after their expiry date has passed. Preferentially, and following strengthening of regulatory systems in low/middle-income country settings, organisations such as the proposed African Medicines Agency55 could lead on ensuring the quality of antivenom products is acceptable, and on defining appropriate expiry dates.

There would be particular value in extending antivenom expiry dates if the proposed WHO antivenom stockpile for Africa were to become established.56 Efforts in the USA to stockpile medications that protect against certain public health emergencies,57 namely pandemics, have been hindered by the high costs of regularly replacing expired stockpiled products, which are carefully stored, but not used, for long periods of time. In response to this challenge, the FDA has provided various routes for products to be approved for use beyond their initial expiry date.58 Given that a regional stockpile of antivenom would entail storage of a large volume of product in a controlled environment, with appropriate temperature regulation, it is feasible that products could remain safe and effective beyond their expiration date, which could improve the financial viability of this important project. Additional in vivo preclinical evaluation of antivenom products would incur a substantial financial cost but given that antivenom products are expensive to produce,9 this may be cost-effective. The ethical cost of increasing what is already substantial and severe, in vivo preclinical testing would also have to be carefully considered. Many manufacturers will have run real time and accelerated stability studies on their antivenom products to explore what duration of time is acceptable for expiry (ie, beyond the listed expiry). Going forward, manufacturers could consider making these data available, such as described by Morokuma et al,20 to provide additional confidence in extended expiration.

Potential wider disincentives for manufacturers to pursue extension of antivenom expiry dates must be considered. The antivenom market has been fragile and manufacturers of higher-quality products have previously ceased production due to unsustainable economics,54 and there is a theoretical risk that extension of expiry dates could reduce product turnover and further impair financial sustainability. Nevertheless, by reducing waste of antivenom products, it is likely that manufacturers could adjust prices to offset losses while ultimately reducing the cost to health services and the public. The benefit of evaluating products based on quality, which has been pioneered by the WHO antivenom risk–benefit assessment, and removing poor products from the market, is a major step forward and should be further expanded to define evidence-based expiry dates.

A major limitation in this study is the absence of any non-expired SAIMR polyvalent for direct comparison. The reasoning behind this is twofold. First, SAIMR polyvalent is extremely expensive and notably extremely difficult to procure outside of South Africa, with anecdotal evidence of worsening supply issues recently. Second, due to these supply issues, we considered it unethical to use the highly limited quantity of SAIMR polyvalent available to us for research purposes, when they may be required in the event of an envenoming. Despite this, comparison with recent in vivo preclinical data available examining the efficacy of non-expired SAIMR polyvalent versus two similar venoms used in this study, demonstrating highly similar results,44 provides confidence in our conclusion that the expired antivenoms in this study have no demonstrable reduction in preclinical efficacy due to age.

Clearly, the older antivenoms used in this study (1991 and 1994 expiry) would not be considered for clinical use based on their appearance alone. Our results clearly suggest that the apparent instability associated with storage time is not reflected as a change in immunochemical properties or the neutralising potency, but as an increment of the turbidity. Reflecting this, antivenoms from 1997 onwards have favourable quality control profiles largely indistinguishable from what would be expected for in-date products. Therefore, we believe this study provides strong rationale for stakeholders (manufacturers, regulators and health authorities) to explore the use of expired antivenom and the extension of antivenom shelf life. The use of expired antivenom needs to be carefully assessed on a product-by-product and venom-by-venom basis, and confirmation of safety of such products is necessary. However, the evidence, both preclinical17–19 and clinical,21 23 25 demonstrating the long-term retained efficacy of antivenoms should lead to initiatives regarding changing expiry dates that could assist in alleviating chronic antivenom availability shortages globally.

Turks up in arms over killing of stray cat



ISTANBUL:

The killing of a stray cat in Istanbul has triggered petitions, protests and death threats, pushing the president to intervene and the courts to retry the culprit.

On January 1, Ibrahim K. was caught on a security camera in the lobby of the building where he lived kicking to death a stray cat named Eros that his neighbours regularly fed.

He was sentenced in early February to 18 months in jail but was then released for good behaviour, sparking indignation among animal welfare groups and a section of the public in Turkiye, whose large stray cat population is often fed and sheltered.

Some 320,000 people signed an online petition demanding a stiffer sentence and in late February the justice ministry said Ibrahim K. would be retried after it received a night-time call from President Recep Tayyip Erdogan saying he was taking a “personal” interest in the case.

Ibrahim K. was retried on Wednesday in a court building where hundreds of people thronged the corridors and the atmosphere was tense.

The judges increased his sentence by one year but did not order him to be detained, ignoring the demands of animal welfare groups and internet trolls who have sent him death threats.

One animal rights group is to appeal, saying Ibrahim K. should be jailed for the maximum four years allowed by law.

On Thursday, the hashtag #JusticeforEros (#ErosicinAdalet) was trending on X, formerly Twitter, in Turkiye and several major newspapers, including Hurriyet, splashed pictures of the dead cat on their front pages.

Hurriyet carried several articles about Eros and “Ibrahim the killer”.

Several celebrities have joined the Justice for Eros appeal, including Argentinian footballer Mauro Icardi, the star striker at Istanbul giants and reigning Turkish champions Galatasaray.

T-90S Is More and More Common in Ukraine – Why Is That Weird?


The Russian Ministry of Defense has published a new propaganda video that shows some of its tanks meant for the war in Ukraine. It turns out that the T-90S, a main battle tank that was originally designed for export, is also serving in Ukraine.

The T-90S was developed as an export version of the tank.

The T-90 is a family of modern main battle tanks produced in Russia since 1992. The T-90 was designed to replace the T-72, but of course, it didn’t replace anything and the T-72 is still the spine of the Russian armoured forces. The T-90M Proryv, sometimes derisively referred to as Putin’s pride, is technically the most advanced tank in the Russian forces, since the T-14 Armata simply does not exist.

There are several versions of the T-90. The T-90S was developed specifically for export to India, Turkmenistan and Algeria, among other countries interested in the T-90 platform. However, in 2023, these export tanks appeared in Ukraine instead. And now the number of T-90S tanks in Ukraine is increasing. One has to wonder if this means that the Russian forces are lacking tanks.

According to the UK Ministry of Defence, Russia has lost at least 2,600 main battle tanks in Ukraine. Other sources indicate that Russia actually lost more than 3,000 main battle tanks since the beginning of the invasion in February 2022. Russia boasts that it produces tanks in large quantities and quickly, but the truth is that many tanks are now being pulled from long-term storage.

The T-90S tanks that Russia is throwing at Ukraine were most likely produced for other countries, but Russia has no other choice and uses them itself. Maybe the orders are going to be late? There is another explanation – some analysts claim that the buyers could have rejected those tanks due to manufacturing defects.

T-90 tanks are supposed to be modern, with active armour protection, electronic warfare systems and everything that the Russian military industry can offer. But even these tanks are shielding themselves against kamikaze drones with cope cages. They don’t work, because the FPV drones are very maneuverable and can dive under those grilles quite easily.

At least two T-90S tanks were already destroyed in Ukraine. But the T-90S should not be underestimated. The T-90S has a powerful 125 mm gun and a powerful 750 kW engine. It may also have the Tshu-1 self-defence system, which is an IR device that blinds some anti-tank missiles (not all T-90S have it). The Kontakt-5 dynamic armour protection is also supposed to protect the T-90S from total destruction. In addition, T-90 tanks in Ukraine are increasingly seen with jammers, which are supposed to disrupt drones.

Towards a multi-lateral framework for cross-border surveillance and information sharing between Nigeria and neighbouring countries


Summary box

  • Nigeria sits in a geopolitically pivotal health security space in Africa sharing contiguous borders with West and Central African countries – Republic of Benin and the Republic of Niger, Republic of Cameroon, and the Republic of Chad.

  • To strengthen infectious disease cross-border surveillance and response, Nigeria set out to effort to build 5-country multi-lateral consensus, sign bilateral instruments, define a road map, and build capacity for preparedness and response with its neighbors, using a multi-lateral.

  • Sustaining such cross-border collaboration for preparedness and response requires local agency, ownership, and funding.

  • This multi-lateral framework can be leveraged to mitigate other health security risks in the region.

Introduction

West and Central Africa has increasingly become a focal point for Global Health Security in recent times. In the last decade, there has been an increase in the number of infectious disease outbreaks of international concern, a not insignificant amount of them originating in West and Central Africa. Starting with the West African Ebola virus disease outbreak of 2014, countries in this region are responding to an increasing incidence of infectious disease outbreaks with the potential to spill across borders. This trend is against the backdrop of the increasing interaction between man and wildlife as deforestation brings disease reservoirs closer to the living space,1 increasing insecurity due to armed conflict resulting in forced migration across state borders and the resultant wide-ranging displacement of persons.2

Nigeria sits at the intersection of West and Central Africa sharing borders to the east with the Republic of Cameroon and the Chad Republic (both Central African Countries) and to the north and west with the Republic of Niger and the Republic of Benin (both West African), as shown in figure 1.1 Nigeria also sits at the ends of two significant trade and traffic routes. The Trans-Saharan route, a route now important for the historically problematic migration surge to Europe and the catastrophic displacement of persons from the deteriorating security situation in the Sahel. The second key route is the Abidjan-Lagos Corridor Organisation (ALCO), the major regional artery for the movement of goods and people across West Africa. Spanning multiple countries, this route bears the potential to foster the largest contiguous multi-state collaboration in Africa.3 The ALCO processes one of the largest informal movements of persons and goods in Africa. It also feeds into the Mano-River countries—a region at the epicentre of the 2014 Ebola virus disease outbreak. These risk dynamics underscore the crucial need for countries in both regions to have a structured way of sharing surveillance information at the national and subnational levels to strengthen preparedness for future outbreaks.

Following the COVID-19 pandemic in early 2020, countries across West and Central Africa responded to the pandemic with measures beginning, as is often the case with countries in the Global South, at Points of Entry. Measures deployed at airports, seaports and ground crossings differed significantly but can be argued to have had a significant impact on the eventual outcome of the response. It is against this backdrop that key stakeholders in the health security ecosystem in Nigeria set out to build a framework for surveillance and information sharing with its neighbours across West and Central Africa. The scope of this collaboration for the short-term was identified as ‘surveillance and infectious disease information sharing at national and subnational levels across borders’.

From Abidjan-Lagos Corridor Organisation to West African Health Organisation

Previous documented attempts at setting up bilateral and multilateral health security frameworks have noted the difficulty of convincing increasingly sceptical governments of the effectiveness of such initiatives.4 Governments rarely share the same health security priorities, however broadly these frameworks define them; governments hesitate to share data that may inform adverse trade and travel policies; and supranational systems rarely balance language broad or precise enough to incorporate the different legal systems and biases in participating countries.5 These challenges constrained previous attempts to set up a multi-lateral information sharing framework in West Africa—like the attempts to set up a multi-country framework for the sharing of infectious disease outbreak information following the Ebola outbreak of 2018.6 Specifically, the ALCO set out to design and deploy a framework for cross-border surveillance information sharing. The framework sought to cover five countries (Nigeria, Benin, Togo, Ghana and Côte d’Ivoire), highlighting their importance in the region, and the volume of travelers shared through the corridor. After several multi-country workshops, the draft memoranda of understanding and protocols for information sharing at the national and district level was agreed in principle by the technical officers (epidemiologists, IHR focal persons) of the five countries. However, a few countries withheld ministerial approvals. In 2019, the West African Health Organisation (WAHO) adopted the instrument and its ancillary protocols. The information-sharing protocol was adapted to include all 14 member countries of the Economic Community West African States (ECOWAS) and presented at a Ministerial Meeting of the West African Health Assembly. This instrument was important in fulfilling some of the regional health security push for the West African bloc of Nations. In furtherance of this, in 2021, the WAHO and the ECOWAS Regional Centre for Disease Control drafted, reviewed and tested a set of standard operation protocols for information sharing between member states.2 7

However, to achieve full inclusion and satisfy key legal and foreign policy positions, the West African regional solution, although well thought-out, seemed suboptimal for Nigeria. Nigeria sought a framework that also includes its neighbours from Central Africa: Chad and Cameroon who are not party to ECOWAS. Both countries will not be a party to any framework instituted through the ECOWAS platform.

A bespoke instrument that establishes a common epidemiological approach to surveillance information sharing for all of Nigeria’s borders and effectively addresses both the geopolitical and epidemiological peculiarity of Nigeria was needed. The solution currently being explored at the WAHO through the ECOWAS Regional Centre for Surveillance and Disease Control (RCSDC) provided the foundation, in principle, for the instrument that was eventually collaboratively designed.

The Nigerian-anchored multi-lateral, multi-regional solution

Inception: in the shadow of a pandemic

In February 2020, while the world was stirred by the news of an outbreak in China, Port Health Services Nigeria held an inception meeting to discuss cross-border surveillance with stakeholders. This was conceptualised as a first step towards crafting a coherent strategy for cross-border engagement with Nigeria’s neighbors. The objectives of this first engagement included outlining key responsibilities and responsibility-holders within the cross-border surveillance and information-sharing task system and agreeing on a short to medium-term plan for systematically strengthening cross-border surveillance information sharing at the national and district levels.

A key decision from the meeting was the need to set up a National Cross-Border Surveillance Committee (as shown in figure 2).3 The following principles guided the set-up and function of this committee:

Figure 2

A three-tiered management and implementation approach was taken, with;

  • A Steering Committee that handles bilateral agreements and consists of Ministers, the Director of Public Health, the Director of Port Health Services and IHR-NFPs—Nigeria, and equivalent counterpart stakeholders from Nigeria’s four proximal neighbours.

  • A National Technical Committee that is designed to oversee strategies, and activities as well as provide support on implementation.

  • And a coordinating unit that functions as a secretariat which is domiciled at Port Health Services headquarters and is responsible for the planning and facilitation of meetings, and other administrative functions to ensure the hitch-free running of the committee. (A diagram showing the structure and inter-relation of the key coordination mechanisms is shown in figure 2.)

At the land borders, a core committee that comprises key agencies across the national lines are responsible for conducting cross-border meetings and operating a ‘Cross Border Forum’. This group helps translate strategy to implementation supported by implementing partners such as Pro-Health International.

Designing a multi-lateral framework for surveillance and information sharing

The central concept for the framework was simple—a broad multi-lateral platform that provides actionable national and subnational approaches to surveillance information sharing and response. The framework provides broad supra-national guidance for collaboration but allows for specific bilateral agreements that define specific terms of collaboration. A great example of this type of supra-national guidance is the International Civil Aviation Organisation’s Public Health Corridor concept.6 A product of the Take-off Guidance Document, a push to re-start aviation safety in the wake of the early global lockdowns due to COVID-19, the Public Health Corridor concept is a framework that allows ‘two or more States to agree to mutually recognise the implemented public health mitigation measures on one or more [flight] routes between their States’. This means countries with a ‘Corridor’ between them can get ahead of outbreaks and maintain flight arrangements knowing they share proximate risk assessment of the situation and mitigation measures.8

Working through a coordinating unit within the National Technical Committee, key officers from Port Health Services began stakeholder engagements with key national stakeholders in the Point of Entry sector—prioritising stakeholders that operate at ground crossings/land borders (such as the Nigerian Immigration Service, the Nigerian Customs Service, the Nigerian Agricultural Quarantine Service and the Nigeria Border Communities Development Agency). These consultations allowed for an understanding of what these stakeholders consider their roles and the constraints to the execution of their mandates in response to infectious disease outbreaks. A key output of these consultations was the terms of reference (TOR) for the members of the National Cross-Border Technical Committee. The TOR, as well as articles of a multilateral/bilateral memorandum of understanding between countries, was designed through an iterative co-creation process requiring regular consultation sessions.

The key goal in the short term was to hold a meeting of the National Cross-Border (Technical) Committee with key national public health officers from Nigeria’s contiguous neighbours in attendance for further review. The officers invited from the neighbouring countries were the International Health Regulations National Focal Point (IHR-NFP) responsible person and the head of the Port Health Authority (where such exists). At this meeting, there was a facilitated multi-sectoral, multi-lateral review of the draft instruments of collaboration as well as ancillary protocols for information sharing and response. A key outcome was a five-country consensus on the necessity and broad outline of a framework for multi-lateral collaboration on infectious disease surveillance and response.

A vision for regional health security collaboration

A road map for the immediate term

At the national level, this mechanism will continue to be used to drive outbreak information sharing and maintain broad memoranda of collaboration on information sharing and other ancillary activities between the four other countries. These will include holding regular multi-lateral engagements, establishing a bilateral agreement on information sharing and response, developing a mid-term (2–5 years) strategic work plan for Nigeria and the ‘Plus4’ group of countries, and conducting targeted advocacy for funding to commence bilateral meetings between Nigeria and the four neighbouring countries monitoring progress and responding to district-level events. At the subnational level, the approach is to expand the number of ground crossings where structured PoE-level cross-border surveillance forums are established and institutionalised to implement cross-border activities.

We see a few key principles/considerations that may guide the sustainable and effective achievement of the vision above.

Local agency, ownership and funding

Stakeholders at both national and subnational (state, local government, etc) levels must drive the implementation of key activities around maintaining these coordination mechanisms. Three concepts are important here—agency, ownership and local funding. Not only is it necessary that public health officials at subnational and national levels own and drive critical intervention (ownership), but they must also believe their action can bring about the desired outcome and is fully backed by the requisite state authority. Agency and ownership are impossible without dedicated local funding through the statutory budgeting processes. As long as funding for key intervention rests with development partners, agency will be diluted, and ownership will be suboptimal. One of the approaches to ensuring dedicated funding through traditional government funding cycles is sustained advocacy to secure and maintain political will.9

Purchase and maintain political will

It will be near-impossible to achieve bridging of bilateral gaps without securing political will across national and subnational levels as well as between countries. Public health leaders will need to continually work at purchasing and maintaining the necessary political will to push through critical policy positions.9

Leverage the platform provided by regional public health institutes

In the last decade, key regional institutes of health have been set-up to drive health security objectives in Africa. The Africa Centre for Disease Control (CDC) and the ECOWAS RCSDC are two key organisations in that mould. In Central Africa, the Organisation for the Coordination of the Fight Against Endemic Diseases in Central Africa performs a similar regional coordination role. Countries must lean on the ability of these institutes to drive multilateral and bilateral conversations, design, and pursue strategic advocacy and mobilise resources.10

Alignment with the Africa Centre for Disease Control ‘New Public Health Order’ philosophy

The African CDC’s New Public Health Order calls for increased local agency and a more active role for regional coordinating public health institutes. The principles and considerations outlined above will ensure drive to strengthen cross-border surveillance meets both key philosophical positions.11

A road map for the medium and long-term

What potential does this mechanism hold for similar interventions for health security in the region? Here are a few exploratory ideas.

Digitisation of district-level cross border information sharing

A key strategy for achieving the objective of national-level monitoring of the surveillance information sharing at the subnational level is the digitising of the process. This will ensure that there is a birds-eye, real-time bilaterally shared view of outbreak information being shared across borders. The extension of this digitisation to other countries in the region will go a long way to making information sharing more seamless. An example of a digital event-based information-sharing platform with the potential of regional adoption across West and Central Africa is ‘The Surveillance Outbreak Response Management and Analysis System (SORMAS)’ already in use in multiple West African countries.12

Joint capacity building initiatives, advocacy and experience sharing

Joint capacity building (including joint simulation exercises) will help surface gaps in capacity, encourage experience sharing and break down language, cultural and context silos. A deliberate attempt to set up an experience-sharing visit may also help in bridging context and expertise gaps between member states. Also, the holding of joint after-action reviews in the aftermath of outbreaks will offer an opportunity to share experiences.

Operationalisation of a district-level joint investigation and response framework

A point that emerged from discussions at the multi-lateral workshop to discuss surveillance and information sharing was the need to establish a similar framework for sharing resources and expertise in joint investigations and response during an outbreak. Such a framework will ensure that border communities can rely on the expertise and resources of neighboring communities. Sample collection and testing across borders, isolation and/or quarantine of ill and suspected persons, etc are public health interventions for which cross-border action will remain highly sensitive. Establishing a bilateral agreement for how to quickly proceed during fast-moving outbreak situations will ensure public health officers at the district level can get ahead of diseases crossing borders and contain highly volatile situations.

Novel use-cases for multi-lateral coordination mechanisms

A few novel use cases to which this approach may be extended exist. An important and urgent example is the establishment of a regional common picture for biosecurity with countries with which Nigeria shares contiguous borders. To do this, there will be a need to expand the scope for incident reporting to include key Biosecurity priorities (across the chemical, biological and radio-nuclear spectrum) and optimise the current coordination mechanism to include specific objectives like linking civilian (public health institutes, laboratory networks, etc) to military and intelligence agencies.

West avoids seriously confronting Iran as IAEA meet begins



VIENNA:

A quarterly meeting of the UN nuclear watchdog’s main policy-making body began on Monday with Western powers again choosing not to seriously confront Iran over its failure to cooperate with the agency on a range of issues, diplomats said.

It is more than a year since the International Atomic Energy Agency’s 35-nation Board of Governors passed a resolution ordering Iran to cooperate with a years-long IAEA investigation into uranium particles found at undeclared sites, saying it was “essential and urgent” for Iran to explain the traces.

Since then, the number of undeclared sites being investigated has shrunk to two from three but the list of problems between the IAEA and Iran has only grown. Iran failed to fully honour an agreement to re-install IAEA cameras at some sites and in September barred some of the agency’s most valued inspectors.

“I … deeply regret that Iran has yet to reverse its decision to withdraw the designations for several experienced Agency inspectors,” director general Rafael Grossi told the Board meeting.

“Only through constructive and meaningful engagement can all of these concerns be addressed and once again I call upon Iran to cooperate fully and unambiguously with the Agency.”

With Israel’s military offensive in Gaza continuing in response to Hamas’s Oct. 7 attacks, heightening tensions across the Middle East, the United States did not want to risk further diplomatic escalation with Iran by pushing for a resolution against it at the IAEA, diplomats said.

“If you did do an (IAEA Board) resolution right now … it’s too dangerous to do anything that could be construed as a wrong signal that could trigger a miscalculation,” a Western diplomat said, citing various factors.

“The region is in this heightened state, you don’t have a ceasefire or resolution of any sort in Gaza, we don’t have the prospects of any kind of nuclear solution, and … the US is going into presidential elections,” they said.

Diplomats had said before the Board meeting that the three European powers that proposed the last resolution jointly with the United States and generally act in coordination with Washington – Britain, France, and Germany, known as the ‘E3’ – were pushing for a resolution and had drafted a text.

Washington, however, has opposed seeking a resolution against Iran for months, at least in part because of the impending US presidential election in November, diplomats have said, and again it was the most reluctant of the four powers.

The United States and E3 have been vocal in criticising Iran on these and other issues, such as its growing stockpile of enriched uranium that would be enough, if enriched further, to fuel several nuclear bombs. Iran says it has no such intention.

DITA Howitzers for Ukraine – What Makes This Weapon Special?


Ukraine badly needs strong artillery. Russia has a huge advantage in both the number of troops and weapons, so Ukraine must be ahead in terms of technology and the quality of its weapons. That is why the Netherlands is buying nine outstanding DITA self-propelled howitzers for Ukraine. This artillery system has some amazing capabilities.

The DITA is a highly advanced Czech-made self-propelled 155 mm howitzer, based on the earlier DANA. The DANA is a Czechoslovak self-propelled eight-wheel howitzer, in service since 1981. Mobility and speed have always been the main advantages of the DANA, which Ukraine also enjoys. But the DANA is a 152.4 mm howitzer, which is the old Eastern Bloc and Russian standard. Meanwhile, the DITA is a modern interpretation of this weapon, which not only has a lot of impressive technology, but also fires 155 mm rounds.

Why is the calibre important? It is already difficult for the West to supply Ukraine with artillery shells. However, finding 155 mm shells is a bit easier because it is the NATO standard. Such ammunition is produced in Western countries, and although it is also in short supply, it will be easier to produce larger quantities of such shells in the future than to find old Soviet 152.4 mm ammunition.

The DITA is an artillery system of impressive capabilities, made for speed. The location of the opposing artillery can be determined by the flight trajectory of the projectiles – there are counter-battery radars for this purpose. Sometimes it’s best to arrive at the firing site, fire a few shots, and leave before the enemy can fire back – this tactic is called shoot-and-scoot.

The DITA is based on a Tatra 8×8 chassis with a 300 kW engine. On the road, this howitzer moves at 80-90 km/h without problems. It is good off-road as well. After arriving at the intended firing location, DITA prepares for shooting in less than 60 seconds. The hydraulic support legs are lowered, the howitzer barrel is automatically raised and directed towards the target, and the automatic loader begins to operate. The DITA can fire 6 shots per minute. Then the howitzer prepares to move in less than 60.

Best of all, the crew sits safely in an armoured, air-conditioned cab. The crew of DITA consists of only 2-3 people who work far from the ammunition compartment.

The Netherlands is buying 9 Czech DITA howitzers for Ukraine. Just that they may take some time to arrive, because it is a completely new weapon and who knows how quickly these systems can be produced. In any case, Ukraine will need good artillery for a long time and DITA is a good tool to have.

The Netherlands buys a lot of weapons for Ukraine. The Commander of the Dutch Armed Forces, General Onno Eichelsheim himself visited the Czech Republic and inspected not only the DITA howitzers, but also the VERA-NG radar system. He emphasized that military support for Ukraine is still the highest priority of the Netherlands.

Previously, the Netherlands ordered 100 MR-2 anti-aircraft guns from Czech manufacturers and together with the USA and Denmark bought 100 modernized T-72 tanks. The Netherlands thus became one of the main customers of the Czech arms industry. But, of course, with the goal of transferring everything to Ukraine.

General Onno Eichelsheim also echoed what most European leaders are now saying – Europe needs to ramp up its own arms production not only for Ukraine, but also for its own security.

Redefining global health and shifting the balance: the ARC-H principle


Summary box

  • The colonial origins which led to the development of global health as a terminology are long-established.

  • While definitions of global health have evolved to assume a more equitable position, the high to low-income operational direction remains.

  • The ARC-H principle (Access-limited, Resource-limited, Context-limited Healthcare) redefines global health a posteriori according to the practical meaning it has taken on.

  • By reframing the definition using the ARC-H principle, global health expertise can more organically and equitably be allocated.

Introduction

On one hand, ‘global health’ is a straightforward notion of health around the world. On the other, it is a complex concept subject to increasing scrutiny, particularly in light of the evolving discourse on decolonisation.1 Although the definition proposed by Koplan et al (ie, ‘an area for study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide…’) is widely referenced, the term ‘global health’ is subject to a broad range of interpretations.2 This article unpacks the concept’s origins and proposes the ‘ARC-H’ principle as a pragmatic step to rebalance the narrative, not least in pursuit of epistemic justice within global health.3

Origins and interpretations

A recent survey of emergency care practitioners in the UK highlighted the spectrum of interpretations of ‘global health’.4 For instance, a few participants considered that the term applied to international projects undertaken in highly resourced settings. Meanwhile, the label of ‘global health’ is commonly used in relation to:

  • ‘Humanitarian’ response following disasters (including sudden onset, man-made and conflict).

  • The delivery of care in resource-constrained settings.

  • The provision of healthcare to internally displaced populations, refugees, asylum-seekers and undocumented migrants.

  • Efforts to fortify fragile healthcare systems in low-income and middle-income countries (LMICs).

These applications tend to reinforce a high-income-centric narrative that global health takes place ‘elsewhere’ and involves engagement with ‘others’. This infers that expertise flows from settings with higher resources towards those who have less.

In part, this reflects that ‘global health’ originated in Western, high-income parlance. Although it aims to be inclusive as a terminology, it has deep-seated roots in colonialism. When the field of tropical medicine arose in the 19th century, it was unashamedly focused on protecting the health of the colonisers.5 Over time, the discipline began to take greater account of the key sociopolitical determinants of health outcomes and incorporated subjects beyond infectious diseases. With these insights, the more inclusive term of ‘international health’ emerged.6 As the 20th century came to a close, the cross-border implications of healthcare policy and practice became more apparent, and the global south increasingly expressed concern that ‘international’ practice was being used to refer to ‘them’ and not everyone. In this context, ‘global health’ emerged as a term that was intended to be less directional and more universal.7

The legacy of meaning

Despite shifts in terminology, the legacy of this history is that the global health agenda continues to be defined, for the most part, by high-income countries. Power and decision-making are often concentrated in resource-rich institutions at the expense of LMIC partners, often with little or no acknowledgement of their voices and expertise.8 9 Although the concept of global health has evolved to centre around transnational healthcare and universal health equity, it retains an undertone of directionality (ie, ‘doing’ global health involves practitioners from more advanced economies engaging in ‘underdeveloped’ contexts).10 This is despite the fact that mature healthcare systems also face significant and ongoing challenges in equity of access and outcomes (the USA, for instance).11 The majority of published and cited ‘experts’ in global health reside or work in the global north (a geographically dubious term, as is the ‘global south’), and are disproportionately responsible for global health work that is ‘abroad’ and unrelated to domestic healthcare inequity.12

Refresh and re-engagement: the ARC-H principle

Regardless of the definitional complexity of ‘global health’, the term is firmly embedded both theoretically and operationally. Until a concise alternative is identified, it will remain in use. Instead of replacing it, we suggest that greater clarity and precision are required when referring to global health activities and programmes. Rather than navigating a priori definitions in the manner of Koplan et al, or exploring its challenges like Taylor, we look at what it has come to mean pragmatically, a posteriori, and qualify its meaning in order to apply it more inclusively.2 13

ARC-H stands for Access-limited, Resource-limited and/or Context-limited Healthcare. When used as an adjunct to the term global health, ARC-H identifies more clearly the environments, populations and practitioners that are being referenced. The term also reinforces that access, resource and context limitations all contribute to health inequity, resulting in unmet healthcare needs and suboptimal health outcomes.

Access

Access-limited healthcare refers to situations where a well-resourced health system exists but access is not equitable or universal. This challenge manifests especially in middle-income and high-income countries, often as a result of geographical and/or financial barriers to care. Access limitations may also become apparent following sudden-onset disasters (the 2023 earthquake in Turkiye, for example).14 Critics of the focus on ‘access’ will question whether this definition extends to wilderness adventure or remote military medicine. While there is crossover, the difference is that this type of access limitation is often constructed, and the health risks can be offset through resource provision.

Resource

Resource-limited healthcare refers to situations where there is a mismatch between demands for care and the supply of human and other resources (infrastructure and equipment, for example). This term is frequently used in the context of global health to describe the challenges faced by LMIC healthcare systems.

Context

Context-limited healthcare refers to situations where healthcare access is compromised by specific sociopolitical circumstances. Asylum-seeking, internally displaced, refugee and undocumented migrant populations, who often endure barriers to care for unique economic, linguistic and cultural reasons, fall into this category.15 To capture this group purely under the banner of ‘access limitation’ dilutes the specific challenges they face, including in relation to the broader social determinants of health.

The ARC-H principle explicitly labels populations and environments typically associated with global health. As a deliberate by-product, it also serves to re-emphasise the expertise of those with lived (and ongoing) experience of access-limited, resource-limited and context-limited practice, who should rightly be identified as global health practitioners. These individuals have skills, knowledge and attributes that should be highly regarded, irrespective of any affiliation with a ‘global health programme’ produced, exported or influenced by a high-income country.

The natural consequence of this definition is that ownership of the specialty of global health will more logically lie with ARC-H populations. A practical application of this approach is that any programme grant, educational event or conference session labelled ‘global health’ will hopefully resonate with a broader spectrum of participants, amplifying the voices of those with lived experience of access, resource and context limitations.

Conclusion

The ARC-H principle, while neither trail-blazing nor revolutionary, seeks to offload colonial vestiges present within the field and terminology of ‘global health’. It offers a more nuanced perspective on the scope of global health practice and recognises where true global health expertise lies. Its apparent simplicity should not undermine its significance, given the pervasive influence of language among the healthcare community.16

In proposing this revised terminology, we acknowledge our bias and privilege as practitioners currently based in high-income countries. This too warrants critique. Regardless, it is hoped that this perspective creates a constructive dialogue about the potential applicability of ARC-H within the global health lexicon. Its application can assist high-income country practitioners to explain the nature of their work more clearly, while simultaneously redressing residual power imbalances. For colleagues in LMICs, use of the ARC-H terminology will hopefully emphasise their inherent expertise, reinforcing that ‘global health’ is something they actively practice, and not the exclusive domain of those outside looking in.
