[Epidemiological surveillance at the municipal level: evaluation of the degree of implementation].

This study's objective was to evaluate the degree of implementation of epidemiological surveillance activities by the Municipal Health Secretariat in Recife, Pernambuco State, Brazil. The design consisted of a case study with a normative approach. The logical model for epidemiological surveillance was outlined as the basis for selecting criteria that comprised a matrix submitted to specialists using the consensus technique or Delphi Method. This consensual matrix was used as the basis for the questionnaires used in the interviews. Three analytical levels were approached: the central level, 6 health districts, and 62 family health teams. According to the study, epidemiological surveillance has been partially implemented in the municipality, based on the degree of implementation at the three levels (already implemented at the central level and partially implemented in the health districts and family health teams). Despite the decentralization of epidemiological surveillance activities to the municipalities, different levels in the municipal system have different needs in dealing with the standards and norms, including the elaboration of internal guidelines to define responsibilities at the three levels.
