Background
Community Health Workers (CHWs) are crucial in extending healthcare to underserved areas in sub-Saharan Africa (SSA), but they often face challenges like limited training, resources, and support. Effective supervision and support interventions are essential for enhancing CHW performance and improving health outcomes. This study therefore explores the characteristics of supervision and support interventions targeted at CHWs in SSA that contribute to successful outcomes.
Methods
A search of four electronic databases (MEDLINE, EMBASE, Web of Science and Global Index Medicus) and grey literature sites was done for studies published between January 2013 and January 2024. Eligible studies were those focusing on CHWs and interventions involving supervision and support in SSA. The methodological quality of the included studies was assessed, and data extracted were analyzed using thematic and content analyses.
Results
Of 4,169 articles identified, fifty-five were included in the synthesis. Four main intervention types were identified: supervision, job aids, incentives, and training. Successful outcomes were measured through service delivery, program, and staff metrics. Fifty-two studies were assessed to have successful outcomes, and these were marked by ten key characteristics. These included material resource allocation, training and continuing education, stakeholder engagement, integration into existing systems, proper administration and logistics, supportive supervision, quality management, digitization, incentivization, and the enhancement of existing modalities. Leadership, governance and environmental factors emerged as important contextual factors in intervention success.
Conclusion
This study highlights the multifaceted nature of supervision and support interventions, highlighting essential characteristics for successful outcomes. Considering these characteristics during program design can enhance success rates. Future research should prioritize the cost-effectiveness, long-term impact, and sustainability of CHW programs in SSA.
