Introduction: Overcoming the existing crises in hospitals without considering the patients' needs and their satisfaction is impossible. The rate of inpatients satisfaction with different units is one of the important criterion for the evaluation of the quality of hospital services. Methods: The present study was carried out in a cross-sectional method during the spring of 2002 for the evaluation of inpatients satisfaction with services provided in different units of different hospitals (Shafa, Bahonar and Kerman, Darman) affiliated to Kerman University of Medical Sciences.

In the study, the minimum required sample size was 564 patients but for more assurance , 600 patients were interviewed at discharge time. The instrument for showing patient satisfaction was a standard questionnaires of the Ministry of Health Education , Isfahan and Shahid Beheshti University of Medical Sciences. Collected data were analyzed by SPSS software using Chi square and T tests.

 Findings: About 59% of patients were satisfied with hospital service. The highest level of dissatisfaction was shown in the patients' nutrition and hygienic conditions of their rooms and the highest level of satisfaction was shown for the clinics and nursing units. The results indicate no relationship between satisfaction with different hospital units and the patients' age, level of education, duration of hospitalization and marital status.
