Learning Health Systems: A Paradigm Shift in What We Can Do about Digital Health Inequities.

Learning health systems (LHSs) embed social accountability into everyday workflows and can inform how governments build bridges across the digital health divide. They shape partnerships using rapid cycles of data-driven learning to respond to patients' calls to action for equity from digital health. Adopting the LHS approach involves re-distributing power, which is likely to be met with resistance. We use the LHS example of British Columbia's 811 services to highlight how infrastructure was created to provide care and answer questions about access to digital health, outcomes from it and the financial impact passed on to patients. In the concluding section, we offer an accountability framework that facilitates partnerships in making digital health more equitable.

Mechanisms behind gender transformative approaches targeting adolescent pregnancy in low- and middle-income countries: a realist synthesis protocol.

INTRODUCTION: Adolescent pregnancy is defined as pregnancy at the age of 19 or below. Pregnancy and childbirth complications are the most significant cause of death among 15-19-year-old girls. Several studies have indicated that inequitable gender norms can increase the vulnerability of adolescent girls, including violence exposure, early marriage, and adolescent pregnancy. To address these disparities, gender transformative approaches aim to challenge and transform restrictive gender norms, roles, and relations through targeted interventions, promoting progressive changes. This realist review aims to synthesise existing evidence from a broad range of data sources to understand how, why, for whom, and in what contexts gender transformative approaches succeed in reducing adolescent pregnancy in low- and middle-income countries. METHOD AND ANALYSIS: We employ a five-step realist synthesis approach: (1) clarify the scope of review and assessment of published literature, (2) development of initial programme theories, (3) systematic search for evidence, (4) development of refined programme theories, and (5) expert feedback and dissemination of results. This protocol presents the results of the first three steps and provides details of the next steps. We extracted data from 18 studies and outlined eight initial programme theories on how gender transformative approaches targeting adolescent pregnancy work in the first three steps. These steps were guided by experts in the field of sexual and reproductive health, implementation science, and realist methodology. As a next step, we will systematically search evidence from electronic databases and grey literature to identify additional studies eligible to refine the initial programme theories. Finally, we will propose refined programme theories that explain how gender transformative approaches work, why, for whom, and under which circumstances. ETHICS AND DISSEMINATION: Ethics approval is not required because the included studies are published articles and other policy and intervention reports. Key results will be shared with the broader audience via academic papers in open-access journals, conferences, and policy recommendations. The protocol for this realist review is registered in PROSPERO (CRD42023398293).

Socio-spatial equity analysis of relative wealth index and emergency obstetric care accessibility in urban Nigeria.

BACKGROUND: Better geographical accessibility to comprehensive emergency obstetric care (CEmOC) facilities can significantly improve pregnancy outcomes. However, with other factors, such as affordability critical for care access, it is important to explore accessibility across groups. We assessed CEmOC geographical accessibility by wealth status in the 15 most-populated Nigerian cities. METHODS: We mapped city boundaries, verified and geocoded functional CEmOC facilities, and assembled population distribution for women of childbearing age and Meta's Relative Wealth Index (RWI). We used the Google Maps Platform's internal Directions Application Programming Interface to obtain driving times to public and private facilities. City-level median travel time (MTT) and number of CEmOC facilities reachable within 60 min were summarised for peak and non-peak hours per wealth quintile. The correlation between RWI and MTT to the nearest public CEmOC was calculated. RESULTS: We show that MTT to the nearest public CEmOC facility is lowest in the wealthiest 20% in all cities, with the largest difference in MTT between the wealthiest 20% and least wealthy 20% seen in Onitsha (26 vs 81 min) and the smallest in Warri (20 vs 30 min). Similarly, the average number of public CEmOC facilities reachable within 60 min varies (11 among the wealthiest 20% and six among the least wealthy in Kano). In five cities, zero facilities are reachable under 60 min for the least wealthy 20%. Those who live in the suburbs particularly have poor accessibility to CEmOC facilities. CONCLUSIONS: Our findings show that the least wealthy mostly have poor accessibility to care. Interventions addressing CEmOC geographical accessibility targeting poor people are needed to address inequities in urban settings.

Access to critical obstetric care can be lifesaving for pregnant women and their offspring. However, socioeconomic factors are known to affect accessibility to health services across different groups. Here, we assessed peak and off-peak travel times to functional health facilities for women from 15 Nigerian cities, using travel time estimates produced by Google Maps and stratified by wealth status. Travel time to the nearest hospital and the number of hospitals reachable within 60 min varied across cities. The wealthiest 20% across all cities had the shortest travel time and vice versa for the least wealthy 20%. Women who live in the suburbs particularly have poor accessibility. Tailored action is needed to improve access for vulnerable populations living in urban settings.

Equity Promoting Integrated Care: Definition and Future Development.

Over the last three decades, integrated care has emerged as an important health system strategy to improve population health while addressing the unique needs of structurally marginalised communities. However, less attention has been given to the role of integrated care in addressing issues related to inequities in health and health care. In this commentary we introduce the concept of Equity Promoting Integrated Care (EPIC) that situates integrated care in a social justice context to frame the actions necessary to center equity as a priority for integrated care. We suggest that efforts to advance the design and implementation of integrated care should focus on three avenues for future research and practice, namely, the collaborative mobilization of a global network of integrated care stakeholders to advocate for social justice and health equity, investing in equity-focused approaches to implementation science that highlight the importance of social concepts such as colonialism and intersectionality to advance the theory and practice of implementing EPIC models of care, and leveraging innovative approaches to measuring equity-related aspects of integrated care to inform continuous improvement of health systems.

Leveraging big data for improving the estimation of close to reality travel time to obstetric emergency services in urban low- and middle-income settings.

Maternal and perinatal mortality remain huge challenges globally, particularly in low- and middle-income countries (LMICs) where >98% of these deaths occur. Emergency obstetric care (EmOC) provided by skilled health personnel is an evidence-based package of interventions effective in reducing these deaths associated with pregnancy and childbirth. Until recently, pregnant women residing in urban areas have been considered to have good access to care, including EmOC. However, emerging evidence shows that due to rapid urbanization, this so called "urban advantage" is shrinking and in some LMIC settings, it is almost non-existent. This poses a complex challenge for structuring an effective health service delivery system, which tend to have poor spatial planning especially in LMIC settings. To optimize access to EmOC and ultimately reduce preventable maternal deaths within the context of urbanization, it is imperative to accurately locate areas and population groups that are geographically marginalized. Underpinning such assessments is accurately estimating travel time to health facilities that provide EmOC. In this perspective, we discuss strengths and weaknesses of approaches commonly used to estimate travel times to EmOC in LMICs, broadly grouped as reported and modeled approaches, while contextualizing our discussion in urban areas. We then introduce the novel OnTIME project, which seeks to address some of the key limitations in these commonly used approaches by leveraging big data. The perspective concludes with a discussion on anticipated outcomes and potential policy applications of the OnTIME project.

Strengthening capacity in hospitals to reduce perinatal morbidity and mortality through a codesigned intervention package: protocol for a realist evaluation as part of a stepped-wedge trial of the Action Leveraging Evidence to Reduce perinatal morTality and morbidity (ALERT) in sub-Saharan Africa project.

INTRODUCTION: Despite a strong evidence base for developing interventions to reduce child mortality and morbidity related to pregnancy and delivery, major knowledge-implementation gaps remain. The Action Leveraging Evidence to Reduce perinatal morTality and morbidity (ALERT) in sub-Saharan Africa project aims to overcome these gaps through strengthening the capacity of multidisciplinary teams that provide maternity care. The intervention includes competency-based midwife training, community engagement for study design, mentoring and quality improvement cycles. The realist process evaluation of ALERT aims at identifying and testing the causal pathway through which the intervention achieves its impact. METHODS AND ANALYSIS: This realist process evaluation complements the effectiveness evaluation and the economic evaluation of the ALERT intervention. Following the realist evaluation cycle, we will first elicit the initial programme theory on the basis of the ALERT theory of change, a review of the evidence on adoption and diffusion of innovations and the perspectives of the stakeholders. Second, we will use a multiple embedded case study design to empirically test the initial programme theory in two hospitals in each of the four intervention countries. Qualitative and quantitative data will be collected, using in-depth interviews with hospital staff and mothers, observations, patient exit interviews and (hospital) document reviews. Analysis will be guided by the Intervention-Actors-Context-Mechanism-Outcome configuration heuristic. We will use thematic coding to analyse the qualitative data. The quantitative data will be analysed descriptively and integrated in the analysis using a retroductive approach. Each case study will end with a refined programme theory (in-case analysis). Third, we will carry out a cross-case comparison within and between the four countries. Comparison between study countries should enable identifying relevant context factors that influence effectiveness and implementation, leading to a mid-range theory that may inform the scaling up the intervention. ETHICS AND DISSEMINATION: In developing this protocol, we paid specific attention to cultural sensitivity, the do no harm principle, confidentiality and non-attribution. We received ethical approval from the local and national institutional review boards in Tanzania, Uganda, Malawi, Benin, Sweden and Belgium. Written or verbal consent of respondents will be secured after explaining the purpose, potential benefits and potential harms of the study using an information sheet. The results will be disseminated through workshops with the hospital staff and national policymakers, and scientific publications and conferences. TRIAL REGISTRATION NUMBER: PACTR202006793783148.

How do participatory methods shape policy? Applying a realist approach to the formulation of a new tuberculosis policy in Georgia.

OBJECTIVES: This paper presents the iterative process of participatory multistakeholder engagement that informed the development of a new national tuberculosis (TB) policy in Georgia, and the lessons learnt. METHODS: Guided by realist evaluation methods, a multistakeholder dialogue was organised to elicit stakeholders' assumptions on challenges and possible solutions for better TB control. Two participatory workshops were conducted with key actors, interspersed by reflection meetings within the research team and discussions with policymakers. Using concept mapping and causal mapping techniques, and drawing causal loop diagrams, we visualised how actors understood TB service provision challenges and the potential means by which a results-based financing (RBF) policy could address these. SETTING: The study was conducted in Tbilisi, Georgia. PARTICIPANTS: A total of 64 key actors from the Ministry of Labour, Health and Social Affairs, staff of the Global Fund to Fight AIDS, TB and Malaria Georgia Project, the National Centre for Disease Control and Public Health, the National TB programme, TB service providers and members of the research team were involved in the workshops. RESULTS: Findings showed that beyond provider incentives, additional policy components were necessary. These included broadening the incentive package to include institutional and organisational incentives, retraining service providers, clear redistribution of roles to support an integrated care model, and refinement of monitoring tools. Health system elements, such as effective referral systems and health information systems were highlighted as necessary for service improvement. CONCLUSIONS: Developing policies that address complex issues requires methods that facilitate linkages between multiple stakeholders and between theory and practice. Such participatory approaches can be informed by realist evaluation principles and visually facilitated by causal loop diagrams. This approach allowed us leverage stakeholders' knowledge and expertise on TB service delivery and RBF to codesign a new policy.

Cost of Utilising Maternal Health Services in Low- and Middle-Income Countries: A Systematic Review.

BACKGROUND: Cost is a major barrier to maternal health service utilisation for many women in low- and middle-income countries (LMICs). However, comparable evidence of the available cost data in these countries is limited. We conducted a systematic review and comparative analysis of costs of utilising maternal health services in these settings. METHODS: We searched peer-reviewed and grey literature databases for articles reporting cost of utilising maternal health services in LMICs published post-2000. All retrieved records were screened and articles meeting the inclusion criteria selected. Quality assessment was performed using the relevant cost-specific criteria of the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. To guarantee comparability, disaggregated costs data were inflated to 2019 US dollar equivalents. Total adjusted costs and cost drivers associated with utilising each service were systematically compared. Where heterogeneity in methods or non-disaggregated costs was observed, narrative synthesis was used to summarise findings. RESULTS: Thirty-six studies met our inclusion criteria. Many of the studies costed multiple services. However, the most frequently costed services were utilisation of normal vaginal delivery (22 studies), caesarean delivery (13), and antenatal care (ANC) (10). The least costed services were post-natal care (PNC) and post-abortion care (PAC) (5 each). Studies used varied methods for data collection and analysis and their quality ranged from low to high with most assessed as average or high. Generally, across all included studies, cost of utilisation progressively increased from ANC and PNC to delivery and PAC, and from public to private providers. Medicines and diagnostics were main cost drivers for ANC and PNC while cost drivers were variable for delivery. Women experienced financial burden of utilising maternal health services and also had to pay some unofficial costs to access care, even where formal exemptions existed. CONCLUSION: Consensus regarding approach for costing maternal health services will help to improve their relevance for supporting policy-making towards achieving universal health coverage. If indeed the post-2015 mission of the global community is to "leave no one behind," then we need to ensure that women and their families are not facing unnecessary and unaffordable costs that could potentially tip them into poverty.

Reaching health facilities in situations of emergency: qualitative study capturing experiences of pregnant women in Africa's largest megacity.

BACKGROUND: The consequences of delays in travel of pregnant women to reach facilities in emergency situations are well documented in literature. However, their decision-making and actual experiences of travel to health facilities when requiring emergency obstetric care (EmOC) remains a 'black box' of many unknowns to the health system, more so in megacities of low- and middle-income countries which are fraught with wide inequalities. METHODS: This in-depth study on travel of pregnant women in Africa's largest megacity, Lagos, is based on interviews conducted between September 2019 and January 2020 with 47 women and 11 of their relatives who presented at comprehensive EmOC facilities in situations of emergency, requiring some EmOC services. Following familiarisation, coding, and searching for patterns, the data was analysed for emerging themes. RESULTS: Despite recognising danger signs, pregnant women are often faced with conundrums on "when", "where" and "how" to reach EmOC facilities. While the decision-making process is a shared activity amongst all women, the available choices vary depending on socio-economic status. Women preferred to travel to facilities deemed to have "nicer" health workers, even if these were farther from home. Reported travel time was between 5 and 240 min in daytime and 5-40 min at night. Many women reported facing remarkably similar travel experiences, with varied challenges faced in the daytime (traffic congestion) compared to night-time (security concerns and scarcity of public transportation). This was irrespective of their age, socio-economic background, or obstetric history. However, the extent to which this experience impacted on their ability to reach facilities depended on their agency and support systems. Travel experience was better if they had a personal vehicle for travel at night, support of relatives or direct/indirect connections with senior health workers at comprehensive EmOC facilities. Referral barriers between facilities further prolonged delays and increased cost of travel for many women. CONCLUSION: If the goal, to leave no one behind, remains a priority, in addition to other health systems strengthening interventions, referral systems need to be improved. Advocacy on policies to encourage women to utilise nearby functional facilities when in situations of emergency and private sector partnerships should be explored.

e-income countries from a provider's perspective: a systematic review.

INTRODUCTION: Maternal health services are effective in reducing the morbidity and mortality associated with pregnancy and childbirth. We conducted a systematic review on costs of maternal health services in low-income and middle-income countries from the provider's perspective. METHODS: We searched multiple peer-reviewed databases (including African Journal Online, CINAHL Plus, EconLit, Popline, PubMed, Scopus and Web of Science) and grey literature for relevant articles published from year 2000. Articles meeting our inclusion criteria were selected with quality assessment done using relevant cost-focused criteria of the Consolidated Health Economic Evaluation Reporting Standards checklist. For comparability, disaggregated costs data were inflated to 2019 US$ equivalents. Costs and cost drivers were systematically compared. Where heterogeneity was observed, narrative synthesis was used to summarise findings. RESULTS: Twenty-two studies were included, with most studies costing vaginal and/or caesarean delivery (11 studies), antenatal care (ANC) (9) and postabortion care (PAC) (8). Postnatal care (PNC) has been least costed (2). Studies used different methods for data collection and analysis. Quality of peer-reviewed studies was assessed average to high while all grey literature studies were assessed as low quality. Following inflation, estimated provision cost per service varied (ANC (US$7.24-US$31.42); vaginal delivery (US$14.32-US$278.22); caesarean delivery (US$72.11-US$378.940; PAC (US$97.09-US$1299.21); family planning (FP) (US$0.82-US$5.27); PNC (US$5.04)). These ranges could be explained by intercountry variations, variations in provider type (public/private), facility type (primary/secondary) and care complexity (simple/complicated). Personnel cost was mostly reported as the major driver for provision of ANC, skilled birth attendance and FP. Economies of scale in service provision were reported. CONCLUSION: There is a cost savings case for task-shifting and encouraging women to use lower level facilities for uncomplicated services. Going forward, consensus regarding cost component definitions and methodologies for costing maternal health services will significantly help to improve the usefulness of cost analyses in supporting policymaking towards achieving Universal Health Coverage.

Cost of maternal health services in low and middle-income countries: protocol for a systematic review.

INTRODUCTION: There is substantial evidence that maternal health services across the continuum of care are effective in reducing morbidities and mortalities associated with pregnancy and childbirth. There is also consensus regarding the need to invest in the delivery of these services towards the global goal of achieving Universal Health Coverage in low/middle-income countries (LMICs). However, there is limited evidence on the costs of providing these services. This protocol describes the methods and analytical framework to be used in conducting a systematic review of costs of providing maternal health services in LMICs. METHODS: African Journal Online, CINAHL Plus, EconLit, Embase, Global Health Archive, Popline, PubMed and Scopus as well as grey literature databases will be searched for relevant articles which report primary cost data for maternal health service in LMICs published from January 2000 to June 2019. This search will be conducted without implementing any language restrictions. Two reviewers will independently search, screen and select articles that meet the inclusion criteria, with disagreements resolved by discussions with a third reviewer. Quality assessment of included articles will be conducted based on cost-focused criteria included in globally recommended checklists for economic evaluations. For comparability, where feasible, cost will be converted to international dollar equivalents using purchasing power parity conversion factors. Costs associated with providing each maternal health services will be systematically compared, using a subgroup analysis. Sensitivity analysis will also be conducted. Where heterogeneity is observed, a narrative synthesis will be used. Population contextual and intervention design characteristics that help achieve cost savings and improve efficiency of maternal health service provision in LMICs will be identified. ETHICS AND DISSEMINATION: Ethical approval is not required for this review. The plan for dissemination is to publish review findings in a peer-reviewed journal and present findings at high-level conferences that engage the most pertinent stakeholders.

Designing and evaluating provider results-based financing for tuberculosis care in Georgia: a realist evaluation protocol.

INTRODUCTION: In 2016, Georgian researchers and policymakers were developing a policy to improve the performance of the national tuberculosis (TB) control programme. The research programme 'Designing and Evaluating Provider Results-Based Financing for Tuberculosis Care in Georgia: Understanding Costs, Mechanisms of Effect and Impact (Results4TB)' was initiated to inform the policy formulation phase, document the policy implementation and assess the effectiveness, cost-effectiveness and the processes of change. To achieve this, the research team intends to combine an impact evaluation, a cost-effectiveness study and a realist evaluation (RE) within an overarching theory-informed design. This protocol is the RE component of the programme. METHODS: A realist methodological approach will be adopted to guide the research design and evaluation. RE answers the question of 'what works in which conditions for whom?' and starts with the development of an initial programme theory (IPT). The IPT will feed into other phases of the realist research cycle (study design, data collection, data analysis and synthesis and theory refinement). Data will be collected in a multiple embedded case study design (five intervention and three control sites) through document reviews, in-depth interviews, non-participant observations and context mapping at facility and national levels. Additional data from other research components (cost-effectiveness and impact evaluation) will aid data triangulation. ETHICS AND DISSEMINATION: The Institutional Review Boards of the National Centre for Disease Control and Public Health in Georgia (ref. IRB # 2018-019) and the Institute of Tropical Medicine, Antwerp (ref. IRB #- 1240/18) have granted ethical approval to the study. TRIAL REGISTRATION NUMBER: ISRCTN14667607.
