[Quality assurance at a health center: 2 years' experience].

In the Primary Care field there is very little experience of organizing a quality control programme that covers all aspects of care. In our centre, at the beginning of 1989, a Quality Control Commission (QCC) was formed with the aim of establishing and coordinating these activities. We describe our two year experience in this report, with special emphasis on the programme's organizational side and the methodological difficulties we encountered while introducing the programme.
