Influence of contextual factors on strengthening key strategic and operational levers of primary healthcare to achieve universal health coverage: a protocol for a realist review.

Given the studies are scoping reviews of published articles, ethics approval is not required. Key dissemination strategies will include academic papers, policy briefs and conference presentations. By capturing the relationship between sociopolitical, cultural and economic contexts and the pathways in which PHC levers interact with each other and the broader health system, findings from this review will facilitate the design and development of evidence-based, context-sensitive strategies that will enhance effective and sustainable PHC implementation strategies.
