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

Abstract

Introduction Existing scoping reviews on the link between primary healthcare (PHC) and universal health coverage (UHC) have not sufficiently addressed the underlying causal mechanisms in which key strategic and operational PHC levers contribute to improved health system and realisation of UHC. This realist review aims to examine how key PHC levers work (independently and holistically) to achieve an improved health system and UHC, and the conditions and caveats that influence the outcome.
