This article discusses a study focused on quality care in health services under the Brazilian AIDS Program. Research in 2001-2003 involved three different projects: an in-depth analysis of the predominant health care pattern in five services, a qualitative evaluation of 27 services, and a structured evaluation of 322 services from seven Brazilian states. Through a description of the projects' stages, the authors discuss issues on theoretical and methodological approaches to evaluation of care in health programs. The discussion also focuses on key problems with the applicability and impact of health services evaluation.
