A Scoping Review of Spatial Analysis Approaches Using Health Survey Data in Sub-Saharan Africa.

ABSTRACT: Spatial analysis has become an increasingly used analytic approach to describe and analyze spatial characteristics of disease burden, but the depth and coverage of its usage for health surveys data in Sub-Saharan Africa are not well known. The objective of this scoping review was to conduct an evaluation of studies using spatial statistics approaches for national health survey data in the SSA region. An organized literature search for studies related to spatial statistics and national health surveys was conducted through PMC, PubMed/Medline, Scopus, NLM Catalog, and Science Direct electronic databases. Of the 4,193 unique articles identified, 153 were included in the final review. Spatial smoothing and prediction methods were predominant (n = 108), followed by spatial description aggregation (n = 25), and spatial autocorrelation and clustering (n = 19). Bayesian statistics methods and lattice data modelling were predominant (n = 108). Most studies focused on malaria and fever (n = 47) followed by health services coverage (n = 38). Only fifteen studies employed nonstandard spatial analyses (e.g., spatial model assessment, joint spatial modelling, accounting for survey design). We recommend that for future spatial analysis using health survey data in the SSA region, there must be an improve recognition and awareness of the potential dangers of a naïve application of spatial statistical methods. We also recommend a wide range of applications using big health data and the future of data science for health systems to monitor and evaluate impacts that are not well understood at local levels.

Project description:Background:Non-communicable diseases (NCDs) cause a large and growing burden of morbidity and mortality in sub-Saharan Africa. Prospective cohort studies are key to study multiple risk factors and chronic diseases and are crucial to our understanding of the burden, aetiology and prognosis of NCDs in SSA. We aimed to identify the level of research output on NCDs and their risk factors collected by cohorts in SSA. Methods:We conducted a scoping review to map the extent of current NCDs research in SSA by identifying studies published after the year 2000 using prospectively collected cohort data on any of the six NCDs (cardiovascular diseases, diabetes, obesity, chronic kidney disease, chronic respiratory diseases, and cancers), ≥1 major risk factor (other than age and sex), set only within SSA, enrolled ≥500 participants, and ≥12 months of follow-up with ≥2 data collection points (or with plans to). We performed a systematic search of databases, a manual search of references lists from included articles and the INDEPTH network website, and study investigators from SSA were contacted for further articles. Results:We identified 30 cohort studies from the 101 included articles. Eighteen countries distributed in West, Central, East and Southern Africa, were represented. The majority (27%) set in South Africa. There were three studies including children, twenty with adults, and seven with both. 53% of cohorts were sampled in general populations, 47% in clinical populations, and 1 occupational cohort study. Hypertension (n = 23) was most commonly reported, followed by obesity (n = 16), diabetes (n = 15), CKD (n = 6), COPD (n = 2), cervical cancer (n = 3), and breast cancer (n = 1). The majority (n = 22) reported data on at least one demographic/environmental, lifestyle, or physiological risk factor but these data varied greatly. Conclusions:Most studies collected data on a combination of hypertension, diabetes, and obesity and few studies collected data on respiratory diseases and cancer. Although most collected data on different risk factors the methodologies varied greatly. Several methodological limitations were found including low recruitment rate, low retention rate, and lack of validated and standardized data collection. Our results could guide potential collaborations and maximize impact to improve our global understanding of NCDs (and their risk factors) in SSA and also to inform future research, as well as policies.

Project description:Background: Cervical cancer remains one of the top causes of cancer mortality among African women. Cervical cancer screening and early detection and treatment of precancer is one of the evidence-based interventions to reduce incidence and mortality. The application of community-based participatory research (CBPR) has been used in the United States to improve participation in screening and reduce cervical cancer disparities. However, it is unclear whether these engaged approaches have been used in sub-Saharan African to address disparities related to cervical cancer mortality. Objectives: Highlight community engagement in cervical cancer prevention and control in Sub-Saharan Africa (SSA), describe the community engagement efforts that are currently being used, and to describe the best practices for community engagement toward the end-goal of cervical cancer prevention and control. Methods: We searched PubMed, Embase, CINHAL, African Journals Online (AJOL), and African Index Medicus-WHO from inception until June 8, 2020. After screening 620 titles and abstracts, and reviewing 56 full-text articles according to inclusion and exclusion criteria, 9 articles met the selection criteria and were included. Relevant data variables were extracted from the included articles and a narrative synthesis was performed. Results: Between 2005 and 2019, 9 articles describing research in Ghana, Kenya, Zambia, Senegal, South Africa, and Nigeria were included. These articles described work that largely took place in rural settings predominantly among women age 15-65 years. Leveraging community networks such as community health workers, religious organizations, traditional leaders, and educational institutions increased awareness of cervical cancer. Working within existing social structures and training community members through the research effort were promising methods for addressing the disparities in cervical cancer incidence and mortality among communities. Discussion: The findings of this scoping review have contributed to the understanding of which novel approaches to community-based practices can be used to address cervical cancer disparities among SSA communities that carry a disproportionate disease burden. Community engagement in the research process, while effortful, has shown to be beneficial to researchers and to the communities that they serve, and provides valuable next steps in the effort to address cervical cancer disparities in SSA.

Project description:ObjectiveHealth-related research in sub-Saharan Africa (SSA) has grown over the years. However, concerns have been raised about the state of research ethics committees (RECs). This scoping review examines the literature on RECs for health-related research in SSA and identifies strategies that have been applied to strengthen the RECs. It focuses on three aspects of RECs: regulatory governance and leadership, administrative and financial capacity and technical capacity of members.DesignA scoping review of published literature, including grey literature, was conducted using the Joanna Briggs Institute approach.Data sourcesBioOne, CINAHL, Embase (via Ovid), Education Abstracts, Global Health, Google Scholar, Jstor, OpenEdition (French), Philosopher's Index, PsycINFO, PubMed, Science Citation and Expanded Index (Web of Science), reference lists of included studies and specific grey literature sources.Eligibility criteriaWe included empirical studies on RECs for health-related research in SSA, covering topics on REC leadership and governance, administrative and financial capacity and the technical capacity of REC members. We included studies published between 01 January 2000 and 18 February 2022 and written in English, French, Portuguese or Swahili.Data extraction and synthesisTwo independent reviewers screened the records. Data were extracted by one reviewer and cross-checked by another. Owing to the heterogeneity of included studies, thematic analysis was used.ResultsWe included 54 studies. The findings show that most RECs in SSA work under significant administrative and financial constraints, with few opportunities for capacity building for committee members. This has an impact on the quality of reviews and the overall performance of RECs. Although most countries have national governance systems for RECs, they lack regulations on accountability, transparency and monitoring of RECs.ConclusionsThis review provides a comprehensive overview of the literature on RECs for health-related research in SSA and contributes to our understanding of how RECs can be strengthened.

Project description:INTRODUCTION:Previous studies have attempted to review the vast body of evidence on adolescent sexual and reproductive health (ASRH), but none has focused on a complete mapping and synthesis of the body of inquiry and evidence on ASRH in sub-Saharan Africa (SSA). Such a comprehensive scoping is needed, however, to offer direction to policy, programming and future research. We aim to undertake a scoping review of studies on ASRH in SSA to capture the landscape of extant research and findings and identify gaps for future research. METHODS AND ANALYSIS:This protocol is designed using the framework for scoping reviews developed by the Joanna Briggs Institute. We will include English and French language peer-reviewed publications and grey literature on ASRH (aged 10-19) in SSA published between January 2010 and June 2019. A three-step search strategy involving an initial search of three databases to refine the keywords, a full search of all databases and screening of references of previous review studies for relevant articles missing from our full search will be employed. We will search AJOL, JSTOR, HINARI, Scopus, Science Direct, Google Scholar and the websites for the WHO, UNICEF, UNFPA, UNESCO and Guttmacher Institute. Two reviewers will screen the titles, abstracts and full texts of publications for eligibility and inclusion-using Covidence (an online software). We will then extract relevant information from studies that meet the inclusion criteria using a tailored extraction frame and template. Extracted data will be analysed using descriptive statistics and thematic analysis. Results will be presented using tables and charts and summaries of key themes arising from available research findings. ETHICS AND DISSEMINATION:Ethical approval is not required for a scoping review as it synthesises publicly available publications. Dissemination will be through publication in a peer-review journal and presentation at relevant conferences and convening of policymakers and civil society organisations working on ASRH in SSA.

Project description:Leadership is a critical component of a health system and may be particularly important in Sub-Saharan Africa, where clinicians take on significant management responsibilities. However, there has been little investment in strengthening leadership in this context, and evidence is limited on what leadership capabilities are most important or how effective different leadership development models are. This scoping review design used Arksey and O'Malley's approach of identifying the question and relevant studies, selection, charting of data, summarizing of results and consultation. A comprehensive search strategy was used that included published and unpublished primary studies and reviews. Seven databases were searched, and papers written in English and French between 1979 and 2019 were included. Potential sources were screened against inclusion and exclusion criteria. Data were grouped into common categories and summarized in tables; categories included conceptual approach to leadership; design of intervention; evaluation method; evidence of effectiveness; and implementation lessons. The findings were then analysed in the context of the review question and objectives. Twenty-eight studies were included in the review out of a total of 495 that were initially identified. The studies covered 23 of the 46 countries in Sub-Saharan Africa. The leadership development programmes (LDPs) described were diverse in their design. No consistency was found in the conceptual approaches they adopted. The evaluation methods were also heterogeneous and often of poor quality. The review showed how rapidly leadership has emerged as a topic of interest in health care in Sub-Saharan Africa. Further research on this subject is needed, in particular in strengthening the conceptual and competency frameworks for leadership in this context, which would also inform better evaluation. Our findings support the need for LDPs to be accredited, better integrated into existing systems and to put greater emphasis on institutionalization and financial sustainability from their early development.
