This study aimed to identify and analyze the use of the Basic Health Care Information System-SIAB by the family health care team, identifying the aim, possible difficulties and facilities of using these forms. This is an exploratory, descriptive study with a qualitative approach. We have used semi-structured taped interviews with the family health care team in Franca - São Paulo - Brazil. The analysis was structured into four groups: the usage of SIAB as a work instrument for the health care team; contradictions in the usage of SIAB; limitations as to data input; and suggestions on how to solve these problems. We will show that the team's use and involvement with SIAB is sporadic, due to difficulties in analyzing, monitoring and evaluating data for complying with local programs related to community health agents, whose high turnover directly affects the inadequate completion and interpretation of forms, as well as difficulties to understand the aim of these forms.
