It endeavours individuals to identify the background characteristics of health centre users and their perceptions of the efficiency of the services provided. Multistage sampling was employed to select 1451 users. Data were obtained during structured interviews on regular clinic days. Of the people using the health centres, 80.4% were unemployed and 75.9% were women. People aged over 60 accounted for 25.4% of the sample. Users included a disproportionately high number of persons from the lower socioeconomic categories. The proportions of persons of different ethnic and religious groups closely reflected those in the country’s general population. Approximately 74% of the interviewees were satisfied with the performance of the doctors in the health centres. For nurses the satisfaction rating was about 10% higher. The greatest needs for improvement were perceived to be in pharmacists’ and doctors’ services, with particular reference to waiting times.[email protected].
