Delivering health and nutrition interventions for women and children in different conflict contexts: a framework for decision making on what, when, and how.

Existing global guidance for addressing women's and children's health and nutrition in humanitarian crises is not sufficiently contextualised for conflict settings specifically, reflecting the still-limited evidence that is available from such settings. As a preliminary step towards filling this guidance gap, we propose a conflict-specific framework that aims to guide decision makers focused on the health and nutrition of women and children affected by conflict to prioritise interventions that would address the major causes of mortality and morbidity among women and children in their particular settings and that could also be feasibly delivered in those settings. Assessing local needs, identifying relevant interventions from among those already recommended for humanitarian settings or universally, and assessing the contextual feasibility of delivery for each candidate intervention are key steps in the framework. We illustratively apply the proposed decision making framework to show what a framework-guided selection of priority interventions might look like in three hypothetical conflict contexts that differ in terms of levels of insecurity and patterns of population displacement. In doing so, we aim to catalyse further iteration and eventual field-testing of such a decision making framework by local, national, and international organisations and agencies involved in the humanitarian health response for women and children affected by conflict.

The political and security dimensions of the humanitarian health response to violent conflict.

The nature of armed conflict throughout the world is intensely dynamic. Consequently, the protection of non-combatants and the provision of humanitarian services must continually adapt to this changing conflict environment. Complex political affiliations, the systematic use of explosive weapons and sexual violence, and the use of new communication technology, including social media, have created new challenges for humanitarian actors in negotiating access to affected populations and security for their own personnel. The nature of combatants has also evolved as armed, non-state actors might have varying motivations, use different forms of violence, and engage in a variety of criminal activities to generate requisite funds. New health threats, such as the COVID-19 pandemic, and new capabilities, such as modern trauma care, have also created new challenges and opportunities for humanitarian health provision. In response, humanitarian policies and practices must develop negotiation and safety capabilities, informed by political and security realities on the ground, and guidance from affected communities. More fundamentally, humanitarian policies will need to confront a changing geopolitical environment, in which traditional humanitarian norms and protections might encounter wavering support in the years to come.

Delivering health interventions to women, children, and adolescents in conflict settings: what have we learned from ten country case studies?

Armed conflict disproportionately affects the morbidity, mortality, and wellbeing of women, newborns, children, and adolescents. Our study presents insights from a collection of ten country case studies aiming to assess the provision of sexual, reproductive, maternal, newborn, child, and adolescent health and nutrition interventions in ten conflict-affected settings in Afghanistan, Colombia, Democratic Republic of the Congo, Mali, Nigeria, Pakistan, Somalia, South Sudan, Syria, and Yemen. We found that despite large variations in contexts and decision making processes, antenatal care, basic emergency obstetric and newborn care, comprehensive emergency obstetric and newborn care, immunisation, treatment of common childhood illnesses, infant and young child feeding, and malnutrition treatment and screening were prioritised in these ten conflict settings. Many lifesaving women's and children's health (WCH) services, including the majority of reproductive, newborn, and adolescent health services, are not reported as being delivered in the ten conflict settings, and interventions to address stillbirths are absent. International donors remain the primary drivers of influencing the what, where, and how of implementing WCH interventions. Interpretation of WCH outcomes in conflict settings are particularly context-dependent given the myriad of complex factors that constitute conflict and their interactions. Moreover, the comprehensiveness and quality of data remain limited in conflict settings. The dynamic nature of modern conflict and the expanding role of non-state armed groups in large geographic areas pose new challenges to delivering WCH services. However, the humanitarian system is creative and pluralistic and has developed some novel solutions to bring lifesaving WCH services closer to populations using new modes of delivery. These solutions, when rigorously evaluated, can represent concrete response to current implementation challenges to modern armed conflicts.

Health systems resilience in practice: a scoping review to identify strategies for building resilience.

BACKGROUND: Research on health systems resilience has focused primarily on the theoretical development of the concept and its dimensions. There is an identified knowledge gap in the research on how to build resilience in health systems in practice and 'what works' in different contexts. The aim of this study is to identify practical strategies for building resilient health systems from the empirical research on health systems resilience. METHODS: A scoping review included empirical research on health systems resilience from peer-reviewed literature. The search in the electronic databases PubMed, Web of Science, Global Health was conducted during January to March 2021 for articles published in English between 2013 to February 2021. A total of 1771 articles were screened, and data was extracted from 22 articles. The articles included empirical, applied research on strategies for resilience, that observed or measured resilience during shocks or chronic stress through collection of primary data or analysis of secondary data, or if they were a review study of empirical research. A narrative summary was done by identifying action-oriented strategies, comparing them, and presenting them by main thematic areas. RESULTS: The results demonstrate examples of strategies used or recommended within nine identified thematic areas; use of community resources, governance and financing, leadership, surveillance, human resources, communication and collaboration, preparedness, organizational capacity and learning and finally health system strengthening. CONCLUSIONS: The findings emphasize the importance of improved governance and financing, empowered middle-level leadership, improved surveillance systems and strengthened human resources. A re-emphasized focus on health systems strengthening with better mainstreaming of health security and international health regulations are demonstrated in the results as a crucial strategy for building resilience. A lack of strategies for recovery and lessons learnt from crises are identified as gaps for resilience in future.

Strengthening vaccination delivery system resilience in the context of protracted humanitarian crisis: a realist-informed systematic review.

BACKGROUND: Childhood vaccination is among the most effective public health interventions available for the prevention of communicable disease, but coverage in many humanitarian settings is sub-optimal. This systematic review critically evaluated peer-review and grey literature evidence on the effectiveness of system-level interventions for improving vaccination coverage in protracted crises, focusing on how they work, and for whom, to better inform preparedness and response for future crises. METHODS: Realist-informed systematic review of peer-reviewed and grey literature. Keyword-structured searches were performed in MEDLINE, EMBASE and Global Health, CINAHL, the Cochrane Collaboration and WHOLIS, and grey literature searches performed through the websites of UNICEF, the Global Polio Eradication Initiative (GPEI) and Technical Network for Strengthening Immunization Services. Results were independently double-screened for inclusion on title and abstract, and full text. Data were extracted using a pre-developed template, capturing information on the operating contexts in which interventions were implemented, intervention mechanisms, and vaccination-related outcomes. Study quality was assessed using the MMAT tool. Findings were narratively synthesised. RESULTS: 50 studies were included, most describing interventions applied in conflict or near-post conflict settings in sub-Saharan Africa, and complex humanitarian emergencies. Vaccination campaigns were the most commonly addressed adaptive mechanism (n = 17). Almost all campaigns operated using multi-modal approaches combining service delivery through multiple pathways (fixed and roving), health worker recruitment and training and community engagement to address both vaccination supply and demand. Creation of collaterals through service integration showed generally positive evidence of impact on routine vaccination uptake by bringing services closer to target populations and leveraging trust that had already been built with communities. Robust community engagement emerged as a key unifying mechanism for outcome improvement across almost all of the intervention classes, in building awareness and trust among crisis-affected populations. Some potentially transformative mechanisms for strengthening resilience in vaccination delivery were identified, but evidence for these remains limited. CONCLUSION: A number of interventions to support adaptations to routine immunisation delivery in the face of protracted crisis are identifiable, as are key unifying mechanisms (multi-level community engagement) apparently irrespective of context, but evidence remains piecemeal. Adapting these approaches for local system resilience-building remains a key challenge.

Framing rehabilitation through health policy and systems research: priorities for strengthening rehabilitation.

BACKGROUND: Recent estimates report that 2.4 billion people with health conditions globally could benefit from rehabilitation. While the benefits of rehabilitation for individuals and society have been described in the literature, many individuals, especially in low- and middle-income countries do not have access to quality rehabilitation. As the need for rehabilitation continues to increase, it is crucial that health systems are adequately prepared to meet this need. Practice- and policy-relevant evidence plays an important role in health systems strengthening efforts. The aim of this paper is to report on the outcome of a global consultative process to advance the development of a research framework to stimulate health policy and systems research (HPSR) for rehabilitation, in order to generate evidence needed by key stakeholders. METHODS: A multi-stakeholder participatory technical consultation was convened by WHO to develop a research framework. This meeting included participants from selected Member States, rehabilitation experts, HPSR experts, public health researchers, civil society and other stakeholders from around the world. The meeting focused on introducing systems approaches to stakeholders and deliberating on priority rehabilitation issues in health systems. Participants were allocated to one of four multi-stakeholder groups with a facilitator to guide the structured technical consultations. Qualitative data in the form of written responses to guiding questions were collected during the structured technical consultations. A technical working group was then established to analyse the data and extract its emerging themes. This informed the development of the HPSR framework for rehabilitation and a selection of preliminary research questions that exemplify how the framework might be used. RESULTS: A total of 123 individuals participated in the multi-stakeholder technical consultations. The elaborated framework is informed by an ecological model and puts forth elements of the six WHO traditional building blocks of the health system, while emphasizing additional components pertinent to rehabilitation, such as political priority, engagement and participatory approaches, and considerations regarding demand and access. Importantly, the framework highlights the multilevel interactions needed across health systems in order to strengthen rehabilitation. Additionally, an initial set of research questions was proposed as a primer for how the framework might be used. CONCLUSIONS: Strengthening health systems to meet the increasing need for rehabilitation will require undertaking more HPSR to inform the integration of rehabilitation into health systems globally. We anticipate that the proposed framework and the emerging research questions will support countries in their quest to increase access to rehabilitation for their populations.

Reducing the impact of the coronavirus on disadvantaged migrants and ethnic minorities.

Studies from several countries have shown that the COVID-19 pandemic has disproportionally affected migrants. Many have numerous risk factors making them vulnerable to infection and poor clinical outcome. Policies to mitigate this effect need to take into account public health principles of inclusion, universal health coverage and the right to health. In addition, the migrant health agenda has been compromised by the suspension of asylum processes and resettlement, border closures, increased deportations and lockdown of camps and excessively restrictive public health measures. International organizations including the World Health Organization and the World Bank have recommended measures to actively counter racism, xenophobia and discrimination by systemically including migrants in the COVID-19 pandemic response. Such recommendations include issuing additional support, targeted communication and reducing barriers to accessing health services and information. Some countries have had specific policies and outreach to migrant groups, including facilitating vaccination. Measures and policies targeting migrants should be evaluated, and good models disseminated widely.

An Integrated eDiagnosis Approach (IeDA) versus standard IMCI for assessing and managing childhood illness in Burkina Faso: a stepped-wedge cluster randomised trial.

BACKGROUND: The Integrated eDiagnosis Approach (IeDA), centred on an electronic Clinical Decision Support System (eCDSS) developed in line with national Integrated Management of Childhood Illness (IMCI) guidelines, was implemented in primary health facilities of two regions of Burkina Faso. An evaluation was performed using a stepped-wedge cluster randomised design with the aim of determining whether the IeDA intervention increased Health Care Workers' (HCW) adherence to the IMCI guidelines. METHODS: Ten randomly selected facilities per district were visited at each step by two trained nurses: One observed under-five consultations and the second conducted a repeat consultation. The primary outcomes were: overall adherence to clinical assessment tasks; overall correct classification ignoring the severity of the classifications; and overall correct prescription according to HCWs' classifications. Statistical comparisons between trial arms were performed on cluster/step-level summaries. RESULTS: On average, 54 and 79% of clinical assessment tasks were observed to be completed by HCWs in the control and intervention districts respectively (cluster-level mean difference = 29.9%; P-value = 0.002). The proportion of children for whom the validation nurses and the HCWs recorded the same classifications (ignoring the severity) was 73 and 79% in the control and intervention districts respectively (cluster-level mean difference = 10.1%; P-value = 0.004). The proportion of children who received correct prescriptions in accordance with HCWs' classifications were similar across arms, 78% in the control arm and 77% in the intervention arm (cluster-level mean difference = - 1.1%; P-value = 0.788). CONCLUSION: The IeDA intervention improved substantially HCWs' adherence to IMCI's clinical assessment tasks, leading to some overall increase in correct classifications but to no overall improvement in correct prescriptions. The largest improvements tended to be observed for less common conditions. For more common conditions, HCWs in the control districts performed relatively well, thus limiting the scope to detect an overall impact.

Professional advice for primary healthcare workers in Ethiopia: a social network analysis.

BACKGROUND: In an era of increasingly competitive funding, governments and donors will be looking for creative ways to extend and maximise resources. One such means can include building upon professional advice networks to more efficiently introduce, scale up, or change programmes and healthcare provider practices. This cross-sectional, mixed-methods, observational study compared professional advice networks of healthcare workers in eight primary healthcare units across four regions of Ethiopia. Primary healthcare units include a health centre and typically five satellite health posts. METHODS: One hundred sixty staff at eight primary healthcare units were interviewed using a structured tool. Quantitative data captured the frequency of healthcare worker advice seeking and giving on providing antenatal, childbirth, postnatal and newborn care. Network and actor-level metrics were calculated including density (ratio of ties between actors to all possible ties), centrality (number of ties incident to an actor), distance (average number of steps between actors) and size (number of actors within the network). Following quantitative network analyses, 20 qualitative interviews were conducted with network study participants from four primary healthcare units. Qualitative interviews aimed to interpret and explain network properties observed. Data were entered, analysed or visualised using Excel 6.0, UCINET 6.0, Netdraw, Adobe InDesign and MaxQDA10 software packages. RESULTS: The following average network level metrics were observed: density .26 (SD.11), degree centrality .45 (SD.08), distance 1.94 (SD.26), number of ties 95.63 (SD 35.46), size of network 20.25 (SD 3.65). Advice networks for antenatal or maternity care were more utilised than advice networks for post-natal or newborn care. Advice networks were typically limited to primary healthcare unit staff, but not necessarily to supervisors. In seeking advice, a colleague's level of training and knowledge were valued over experience. Advice exchange primarily took place in person or over the phone rather than over email or online fora. There were few barriers to seeking advice. CONCLUSION: Informal, inter-and intra-cadre advice networks existed. Fellow primary healthcare unit staff were preferred, particularly midwives, but networks were not limited to the primary healthcare unit. Additional research is needed to associate network properties with outcomes and pilot network interventions with central actors.

Contested legitimacy for anthropologists involved in medical humanitarian action: experiences from the 2014-2016 West Africa Ebola epidemic.

The growing involvement of anthropologists in medical humanitarian response efforts has laid bare the moral and ethical consequences that emerge from humanitarian action. Anthropologists are well placed to examine the social, political, cultural and economic dimensions that influence the spread of diseases, and the ways in which to respond to epidemics. Anthropologists are also, with care, able to turn a critical lens on medical humanitarian response. However, there remains some resistance to involving anthropologists in response activities in the field. Drawing on interviews with anthropologists and humanitarian workers involved in the 2014-2016 West African Ebola epidemic, this paper reveals the complex roles taken on by anthropologists in the field and reveals how anthropologists faced questions of legitimacy vis-à-vis communities and responders in their roles in response activities, which focused on acting as 'firefighters' and 'cultural brokers' as well as legitimacy as academic researchers. Whilst these anthropologists were able to conduct research alongside these activities, or draw on anthropological knowledge to inform response activities, questions also arose about the legitimacy of these roles for anthropological academia. We conclude that the process of gaining legitimacy from all these different constituencies is particular to anthropologists and reveals the role of 'giving voice' to communities alongside critiquing medical humanitarianism. Whilst these anthropologists have strengthened the argument for the involvement of anthropologists in epidemic response this anthropological engagement with medical humanitarianism has revealed theoretical considerations more broadly for the discipline, as highlighted through engagement in other fields, especially in human rights and global health.

A case-control study of musculoskeletal impairment: association with socio-economic status, time use and quality of life in post-conflict Myanmar.

BACKGROUND: Musculoskeletal impairments (MSI) are a major global contributor to disability. Evidence suggests entrenched cyclical links between disability and poverty, although few data are available on the link of poverty with MSI specifically. More data are needed on the association of MSI with functioning, socio-economic status and quality of life, particularly in resource-poor settings where MSI is common. METHODS: We undertook a case-control study of the association between MSI and poverty, time use and quality of life in post-conflict Myanmar. Cases were recruited from two physical rehabilitation service-centres, prior to the receipt of any services. One age- (+/- 5 years of case's age) and sex- matched control was recruited per case, from their home community. 108 cases and 104 controls were recruited between July - December 2015. Cases and controls underwent in-depth structured interviews and functional performance tests at multiple time points over a twelve-month period. The baseline characteristics of cases and controls are reported in this manuscript, using multivariate logistic regression analysis and various tests of association. RESULTS: 89% of cases were male, 93% were lower limb amputees, and the vast majority had acquired MSI in adulthood. 69% were not working compared with 6% of controls (Odds Ratio 27.4, 95% Confidence Interval 10.6-70.7). Overall income, expenditure and assets were similar between cases and controls, with three-quarters of both living below the international LMIC poverty line. However, cases' health expenditure was significantly higher than controls' and associated with catastrophic health expenditure and an income gap for one fifth and two thirds of cases respectively. Quality of life scores were lower for cases than controls overall and in each sub-category of quality of life, and cases were far less likely to have participated in productive work the previous day than controls. CONCLUSION: Adults with MSI in Myanmar who are not in receipt of rehabilitative services may be at increased risk of poverty and lower quality of life in relation to increased health needs and limited opportunities to participate in productive work. This study highlights the need for more comprehensive and appropriate support to persons with physical impairments in Myanmar.

Mathematical modelling for health systems research: a systematic review of system dynamics and agent-based models.

BACKGROUND: Mathematical modelling has been a vital research tool for exploring complex systems, most recently to aid understanding of health system functioning and optimisation. System dynamics models (SDM) and agent-based models (ABM) are two popular complementary methods, used to simulate macro- and micro-level health system behaviour. This systematic review aims to collate, compare and summarise the application of both methods in this field and to identify common healthcare settings and problems that have been modelled using SDM and ABM. METHODS: We searched MEDLINE, EMBASE, Cochrane Library, MathSciNet, ACM Digital Library, HMIC, Econlit and Global Health databases to identify literature for this review. We described papers meeting the inclusion criteria using descriptive statistics and narrative synthesis, and made comparisons between the identified SDM and ABM literature. RESULTS: We identified 28 papers using SDM methods and 11 papers using ABM methods, one of which used hybrid SDM-ABM to simulate health system behaviour. The majority of SDM, ABM and hybrid modelling papers simulated health systems based in high income countries. Emergency and acute care, and elderly care and long-term care services were the most frequently simulated health system settings, modelling the impact of health policies and interventions such as those targeting stretched and under resourced healthcare services, patient length of stay in healthcare facilities and undesirable patient outcomes. CONCLUSIONS: Future work should now turn to modelling health systems in low- and middle-income countries to aid our understanding of health system functioning in these settings and allow stakeholders and researchers to assess the impact of policies or interventions before implementation. Hybrid modelling of health systems is still relatively novel but with increasing software developments and a growing demand to account for both complex system feedback and heterogeneous behaviour exhibited by those who access or deliver healthcare, we expect a boost in their use to model health systems.

Evidence on public health interventions in humanitarian crises.

Recognition of the need for evidence-based interventions to help to improve the effectiveness and efficiency of humanitarian responses has been increasing. However, little is known about the breadth and quality of evidence on health interventions in humanitarian crises. We describe the findings of a systematic review with the aim of examining the quantity and quality of evidence on public health interventions in humanitarian crises to identify key research gaps. We identified 345 studies published between 1980 and 2014 that met our inclusion criteria. The quantity of evidence varied substantially by health topic, from communicable diseases (n=131), nutrition (n=77), to non-communicable diseases (n=8), and water, sanitation, and hygiene (n=6). We observed common study design and weaknesses in the methods, which substantially reduced the ability to determine causation and attribution of the interventions. Considering the major increase in health-related humanitarian activities in the past three decades and calls for a stronger evidence base, this paper highlights the limited quantity and quality of health intervention research in humanitarian contexts and supports calls to scale up this research.

Clinical assessment is a neglected component of outbreak preparedness: evidence from refugee camps in Greece.

BACKGROUND: Refugees may have an increased vulnerability to infectious diseases, and the consequences of an outbreak are more severe in a refugee camp. When an outbreak is suspected, access to clinical information is critical for investigators to verify that an outbreak is occurring, to determine the cause and to select interventions to control it. Experience from previous outbreaks suggests that the accuracy and completeness of this information is poor. This study is the first to assess the adequacy of clinical characterisation of acute medical illnesses in refugee camps. The objective is to direct improvements in outbreak identification and management in this vulnerable setting. METHODS: We collected prospective data in 13 refugee camps in Greece. We passively observed consultations where patients presented with syndromes that might warrant inclusion into an existing syndromic surveillance system and then undertook a structured assessment of routine clinical data collection to examine the extent to which key clinical parameters required for an outbreak response were ascertained and then documented. RESULTS: A total of 528 patient consultations were included. The most common presenting condition was an acute respiratory illness. Clinicians often made a comprehensive clinical assessment, especially for common syndromes of respiratory and gastrointestinal conditions, but documented their findings less frequently. For fewer than 5% of patients were a full set of vital signs ascertained and so the severity of patient illnesses was largely unknown. In only 11% of consultations was it verified that a patient who met the case criteria for syndromic surveillance reporting based on an independent assessment was reported into the system. DISCUSSION: Opportunities exist to strengthen clinical data capture and recording in refugee camps, which will produce a better calibrated and directed public health response. CONCLUSION: Information of significant utility for outbreak response is collected at the clinical interface and we recommend improving how this information is recorded and linked into surveillance systems.

Syrian refugees in Greece: experience with violence, mental health status, and access to information during the journey and while in Greece.

BACKGROUND: Since 2015, Europe has been facing an unprecedented arrival of refugees and migrants: more than one million people entered via land and sea routes. During their travels, refugees and migrants often face harsh conditions, forced detention, and violence in transit countries. However, there is a lack of epidemiological quantitative evidence on their experiences and the mental health problems they face during their displacement. We aimed to document the types of violence experienced by migrants and refugees during their journey and while settled in Greece, and to measure the prevalence of anxiety disorders and access to legal information and procedures. METHODS: We conducted a cross-sectional population-based quantitative survey combined with an explanatory qualitative study in eight sites (representing the range of settlements) in Greece during winter 2016/17. The survey consisted of a structured questionnaire on experience of violence and an interviewer-administered anxiety disorder screening tool (Refugee Health Screener). RESULTS: In total, 1293 refugees were included, of whom 728 were Syrians (41.3% females) of median age 18 years (interquartile range 7-30). Depending on the site, between 31% and 77.5% reported having experienced at least one violent event in Syria, 24.8-57.5% during the journey to Greece, and 5-8% in their Greek settlement. Over 75% (up to 92%) of respondents ≥15 years screened positive for anxiety disorder, which warranted referral for mental health evaluation, which was only accepted by 69-82% of participants. Access to legal information and assistance about asylum procedures were considered poor to non-existent for the majority, and the uncertainty of their status exacerbated their anxiety. CONCLUSIONS: This survey, conducted during a mass refugee crisis in a European Community country, provides important data on experiences in different refugee settings and reports the high levels of violence experienced by Syrian refugees during their journeys, the high prevalence of anxiety disorders, and the shortcomings of the international protective response.

Interventions to improve access to cataract surgical services and their impact on equity in low- and middle-income countries.

BACKGROUND: Cataract is the leading cause of blindness in low- and middle-income countries (LMICs), and the prevalence is inequitably distributed between and within countries. Interventions have been undertaken to improve cataract surgical services, however, the effectiveness of these interventions on promoting equity is not known. OBJECTIVES: To assess the effects on equity of interventions to improve access to cataract services for populations with cataract blindness (and visual impairment) in LMICs. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 3), MEDLINE Ovid (1946 to 12 April 2017), Embase Ovid (1980 to 12 April 2017), LILACS (Latin American and Caribbean Health Sciences Literature Database) (1982 to 12 April 2017), the ISRCTN registry (www.isrctn.com/editAdvancedSearch); searched 12 April 2017, ClinicalTrials.gov (www.clinicaltrials.gov); searched 12 April 2017 and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en); searched 12 April 2017. We did not use any date or language restrictions in the electronic searches for trials. SELECTION CRITERIA: We included studies that reported on strategies to improve access to cataract services in LMICs using the following study designs: randomised and quasi-randomised controlled trials (RCTs), controlled before-and-after studies, and interrupted time series studies. Included studies were conducted in LMICs, and were targeted at disadvantaged populations, or disaggregated outcome data by 'PROGRESS-Plus' factors (Place of residence; Race/ethnicity/ culture/ language; Occupation; Gender/sex; Religion; Education; Socio-economic status; Social capital/networks. The 'Plus' component includes disability, sexual orientation and age). DATA COLLECTION AND ANALYSIS: Two authors (JR and JP) independently selected studies, extracted data and assessed them for risk of bias. Meta-analysis was not possible, so included studies were synthesised in table and text. MAIN RESULTS: From a total of 2865 studies identified in the search, two met our eligibility criteria, both of which were cluster-RCTs conducted in rural China. The way in which the trials were conducted means that the risk of bias is unclear. In both studies, villages were randomised to be either an intervention or control group. Adults identified with vision-impairing cataract, following village-based vision and eye health assessment, either received an intervention to increase uptake of cataract surgery (if their village was an intervention group), or to receive 'standard care' (if their village was a control group).One study (n = 434), randomly allocated 26 villages or townships to the intervention, which involved watching an informational video and receiving counselling about cataract and cataract surgery, while the control group were advised that they had decreased vision due to cataract and it could be treated, without being shown the video or receiving counselling. There was low-certainty evidence that providing information and counselling had no effect on uptake of referral to the hospital (OR 1.03, 95% CI 0.63 to 1.67, 1 RCT, 434 participants) and little or no effect on the uptake of surgery (OR 1.11, 95% CI 0.67 to 1.84, 1 RCT, 434 participants). We assessed the level of evidence to be of low-certainty for both outcomes, due to indirectness of evidence and imprecision of results.The other study (n = 355, 24 towns randomised) included three intervention arms: free surgery; free surgery plus reimbursement of transport costs; and free surgery plus free transport to and from the hospital. These were compared to the control group, which was reminded to use the "low-cost" (˜USD 38) surgical service. There was low-certainty evidence that surgical fee waiver with/without transport provision or reimbursement increased uptake of surgery (RR 1.94, 95% CI 1.14 to 3.31, 1 RCT, 355 participants). We assessed the level of evidence to be of low-certainty due to indirectness of evidence and imprecision of results.Neither of the studies reported our primary outcome of change in prevalence of cataract blindness, or other outcomes such as cataract surgical coverage, surgical outcome, or adverse effects. Neither study disaggregated outcomes by social subgroups to enable further assessment of equity effects. We sought data from both studies and obtained data from one; the information video and counselling intervention did not have a differential effect across the PROGRESS-Plus categories with available data (place of residence, gender, education level, socioeconomic status and social capital). AUTHORS' CONCLUSIONS: Current evidence on the effect on equity of interventions to improve access to cataract services in LMICs is limited. We identified only two studies, both conducted in rural China. Assessment of equity effects will be improved if future studies disaggregate outcomes by relevant social subgroups. To assist with assessing generalisability of findings to other settings, robust data on contextual factors are also needed.
