[Evaluating the implementation of STD/AIDS prevention activities in primary health care facilities: a case study in Greater Metropolitan São Paulo, Brazil].

Since the 1990 s, international guidelines have recommended the incorporation of STD/AIDS prevention in primary care. In Brazil, the Ministry of Health has made investments to include such preventive activities. This in-depth case study is an evaluation of the implementation of these activities in a family health unit in Greater Metropolitan São Paulo. The study analyzed the unit's activities as a whole and the specific STD/ AIDS prevention activities by means of direct observations and semi-structured interviews with the unit's professional health staff. The unit's technological characteristics were similar to those of traditional Brazilian primary care services, with limited potential for achieving the principle of comprehensive care. STD/AIDS prevention activities had been incorporated, but were devoid of important technological meanings like dialogue and specific attention to users' uniqueness. This characteristic and others reveal a tension between the program's technological proposals and the current technological profile of primary care. However, the identification of this tension could favor reflection on new values in routine primary care, thereby favoring the achievement of more comprehensive technological arrangements.
