[The implementation of decentralized health systems: a comparative study of five cases in Bahia, Brazil].

Understanding the effects of health decentralization policies in Brazil requires different methodological approaches to capture the issue's complexity from distinct angles. Five case studies were thus performed to evaluate the degree of implementation of components related to decentralization of the health system management in selected municipalities (counties) in Bahia State, Brazil. A logical model was elaborated with definitions related to policy goals.
