“…For African geographic regions, we will adapt a geographic African filter validated by the South African Cochrane Centre,30 by correcting the name ‘Mayotte’ and including alternative missing African country names (eg, ‘Ruanda’, ‘Comoros’ and ‘Cabo Verde’). We will use the list of African region names used to develop the low-income and middle-income countries’ geographic search filter by the Cochrane Effective Practice and Organisation of Care, in collaboration with the WHO and Campbell Collaboration 31 32…”

Mapping health service coverage inequalities in Africa: a scoping review protocol

et al. 2023

IntroductionAddressing inequities in health service coverage is a global priority, especially with the resurgence of interest in universal health coverage. However, in Africa, which has the lowest health service coverage index, there is limited information on the progress of countries in addressing inequalities related to health services. Thus, we seek to map the evidence on inequalities in health service coverage in Africa.Methods and analysisWe will conduct a scoping review following the Joanna Briggs Institute Manual for Evidence Synthesis. We preregistered this protocol with the Open Science Framework on 26 July 2022 (https://osf.io/zd5bt). We will consider any empirical research that assesses inequalities in relation to services for reproductive, maternal, newborn and child health (eg, family planning), infectious diseases (eg, tuberculosis treatment) and non-communicable diseases (eg, cervical cancer screening) in Africa. We will search MEDLINE, Embase, Web of Science, CINAHL, PsycINFO and Cochrane Library from their inception onwards. We will also hand-search Google and Global Index Medicus, and screen reference lists of relevant studies. We will evaluate studies for eligibility and extract data from included studies using pre-piloted and standardised forms. We will further extract a core set of health service coverage indicators, which are disaggregated by place of residence, race/ethnicity/culture, occupation, gender, religion, education, socioeconomic status and social capital plus equity stratifiers. We will summarise data using a narrative approach involving thematic syntheses and descriptive statistics. We will report our findings according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist.Ethics and disseminationEthical approval is not required as primary data will not be collected. This work will contribute to identifying knowledge gaps in the evidence of inequalities in health service coverage in Africa, and propose strategies that could help overcome current challenges. We will disseminate our findings to knowledge users through a publication in a peer-reviewed journal and organisation of workshops.

“…For the exact search on LMIC names, we adopted the ScHARR LMIC filter. 9 Please note that a publication was identified from Martinique, which is located in the Lesser Antilles of the West Indies in the eastern Caribbean Sea and is an overseas region of France. Considering the distinctive race and ethnicity that people from Martinique may have compared to people from France, as well as the scarcity of publications from the Caribbean, the international workgroup has decided to categorize this study in the GBD regions "Latin America and the Caribbean" based on its location for the data analyses.…”

Background Cerebral small vessel disease (cSVD) is a major cause of stroke and dementia. Previous studies on the prevalence of cSVD are mostly based on single geographically-defined cohorts in high-income countries. Studies investigating the prevalence of cSVD in low- and middle-income countries (LMICs) are expanding but have not been systematically assessed. Aim This study aims to systematically review the prevalence of cSVD in LMICs. Results Articles were searched from the Ovid MEDLINE and EMBASE databases from 1st Jan 2000 to 31st March 2022, without language restrictions. Title/abstract screening, full-text review, and data extraction were performed by 2-7 independent reviewers. The prevalence of cSVD and study sample size were extracted by pre-defined world regions and health status. The Risk of Bias for Non-randomized Studies tool was used. The protocol was registered on PROSPERO (CRD42022311133). A meta-analysis of proportion was performed to assess the prevalence of different MRI markers of cSVD and a meta-regression was performed to investigate associations between cSVD prevalence and type of study, age, and male: female ratio. Of 2,743 studies identified, 42 spanning 12 global regions were included in the systematic review. Most of the identified studies were from China (n=23). The median prevalence of moderate-to-severe white matter hyperintensities (WMH) was 20.5%, 40.5%, and 58.4% in the community, stroke, and dementia groups, respectively. The median prevalence of lacunes was 0.8% and 33.52% in the community and stroke groups. The mean prevalence of cerebral microbleeds (CMB) was 10.7% and 22.4% in the community and stroke groups. The mean prevalence of moderate-to-severe perivascular spaces was 25.0% in the community. Meta-regression analyses showed that the weighted median age (51.4 ± 0.0 years old; range: 36.3-80.2) was a significant predictor of the prevalence of moderate-to-severe WMH and lacunes, while the type of study was a significant predictor of the prevalence of CMB. The heterogeneity of studies was high (> 95%). Male participants were overrepresented. Conclusions This systematic review and meta-analysis provide data on cSVD prevalence in LMICs and demonstrated the high prevalence of the condition. cSVD research in LMICs is being published at an increasing rate, especially between 2010-2022. More data is particularly needed from Sub-Saharan Africa & Central Europe, Eastern Europe & Central Asia.

“…ABC drafted the preliminary version of the search strategy for Ovid MEDLINE. The search terms were based on previous works to reflect three concepts: 1) intervention [27,28], 2) health system functionality [11,29], and 3) low-and middle-income regions [30,31]. For the latter, we used a search filter developed by the Cochrane Effective Practice and Organisation of Care (EPOC) in collaboration with the WHO and Campbell Collaboration [30,31].…”

The health challenges in Africa underscore the importance of effectively investing in health systems. Unfortunately, there is no information on systems investments adequate for an effective functional health system. We aimed to address this by conducting a scoping review of existing evidence following the Joanna Briggs Institute Manual for Evidence Synthesis and preregistered with the Open Science Framework (https://osf.io/bvg4z). We included any empirical research describing interventions that contributed to the functionality of health systems in Africa or any low-income or lower-middle-income regions. We searched Web of Science, MEDLINE, Embase, PsycINFO, Cochrane Library, CINAHL, and ERIC from their inception, and hand-searched other relevant sources. We summarized data using a narrative approach involving thematic syntheses and descriptive statistics. We identified 554 unique reports describing 575 interventions, of which 495 reported evidence of effectiveness. Most interventions were undertaken in Africa (80.9%), covered multiple elements of health systems (median: 3), and focused on service delivery (77.4%) and health workforce (65.6%). Effective interventions contributed to improving single (35.6%) or multiple (64.4%) capacities of health systems: access to essential services (75.6%), quality of care (70.5%), demand for essential services (38.6%), or health systems resilience (13.5%). For example, telemedicine models which covered software (technologies) and hardware (health workers) elements were used as a strategy to address issues of access to essential services. We inventoried these effective interventions for improving health systems functionality in Africa. Further analyses could deepen understanding of how such interventions differ in their incorporation of evidence for potential scale across African countries.
