Care coordination in primary health care: an evaluative study in a municipality in the Northeast of Brazil

International and Brazilian studies have highlighted the importance of the coordination of care for the organization of local health systems. This study aimed to analyze the coordination of care by Primary Health Care (PHC) in a municipal health system in the State of Bahia. This study was conducted in the lead municipality of the macro-region and involved two levels of analysis: PHC team and municipal management. Outlining conditions for the study were defined (hypertension and diabetes mellitus) and an objective image corresponding to the coordination of care was developed based on current national and international literature review. Semi-structured interviews with professionals, managers of PHC services were conducted and current documentary sources were also used. It was demonstrated that the coordination of care has not been met by municipal systems, where only 14 of the 22 proposed criteria have been met. The main difficulties and reasons were: a lack of health care protocols and the non-implementation of computer systems and telecommunication technologies. The results and the conceptual framework to assess the coordination of care are relevant contributions to this study, which can be applied to other contexts with similar characteristics.
