What contributes to Primary Health Care effectiveness? Integrative literature review, 2010-2020.

Primary Health Care (PHC) intends to rearrange services to make it more effective. Nevertheless, effectiveness in PHC is quite a challenge. This study reviews several articles regarding the effectiveness improvements in PHC between 2010 and 2020. Ninety out of 8,369 articles found in PubMed and the Virtual Health Library databases search were selected for thematic analysis using the Atlas.ti® 9.0 software. There were four categories identified: strategies for monitoring and evaluating health services, organizational arrangements, models and technologies applied to PHC. Studies concerning the sensitive conditions indicators were predominant. Institutional assessment programs, PHC as a structuring policy, appropriate workforce, measures to increase access and digital technologies showed positive effects. However, payment for performance is still controversial. The expressive number of Brazilian publications reveals the broad diffusion of PHC in the country and the concern on its performance. These findings reassure well-known aspects, but it also points to the need for a logical model to better define what is intended as effectiveness within primary health care as well as clarify the polysemy that surrounds the concept. We also suggest substituting the term "resolvability", commonly used in Brazil, for "effectiveness".
