This study aimed to evaluate the implementation of the Family Health Support Center (FHSC) in three municipalities in the Northern Zona da Mata of Pernambuco, determining the degree of FHSC implementation in these municipalities from the structure and process dimensions, and analyzing the influence of the political and structural context in the variation of the degree of implementation. This is an evaluative study, type 1b implementation analysis, developed in the period from March to August 2015 with FHSC professionals, coordinators from AB, and secretaries of health. The FHSC from the A, B, and C municipalities obtained a degree of implementation of 72% (partially implemented), 81% (implemented), and 68% (partially implemented), respectively. In the context analysis there was a consistency in the results, because the only region where the FHSC was considered implemented was the same one that presented a more favorable context. In similar fashion, the region with the lowest degree of implementation was the one that had a more unfavorable context. It was observed that management that provides suitable conditions for carrying out activities by professionals, whether related to the structure or the process, positively influences the implementation of the intervention.
