[Evaluation of primary care coverage in Salvador, Bahia State, Brazil (2000 to 2007)]

In order to test a method for evaluating coverage of primary healthcare services in Salvador, Bahia State, Brazil (2000-2007), a study of spatial and temporal clusters was performed, with the city and its 12 health districts as the analytical units. The real and potential coverage rates were estimated for various primary care procedures. Estimation of coverage rates used both the Ministry of Health guideline and a second standard aimed at establishing an approximation to the population's health needs. The data were obtained from the Outpatient Information System of the Unified National Health System (SIA-SUS). Low coverage rates were observed, despite a slight increase in real coverage for medical consultations (7.8%) and basic nursing care (66.7%). Meanwhile, dental consultations showed a 40% reduction. The study discussed the possibilities for using the methodology to monitor coverage and its limitations given the deficiencies in the information systems.
