RESUMEN
Information on the cost of health services is essential for good planning and management and the efficient use of resources. We calculated the total costs incurred in running primary health services for one year [1995] in the health district of Enfidha [Tunisia]. The yearly operating expenditure for the health district was 1 219 099 Tunisian dinars and the cost per inhabitant was 17.494 dinars [US dollar 1 = Tunisian dinar 0.950 in 1995]; 65.37% of total costs went on staff and 17.03% on drugs. Looked at another way, 84,96% went on curative services and 14.04% on preventive services.The cost of a consultation for curative care was 6.847dinars, for perinatal care was 2.764 dinars, for immunization was 3.680 and for school visit was 6.680 dinars. The study helps to identify ways in which cost analysis can be used to explore efficiency and resource adequacy in the district
