Background and Objective: Health care systems in different countries are organized to provide services, including prevention, treatment, and rehabilitation of people, and they are influenced by political, economic, and cultural factors. Health and safety are the basic rights of each and every individual in society. This study aimed to assess the satisfaction level of individuals referring to the rural health centers in Darab County in the Fars Province. Materials and Methods: This is a descriptive-analytical study. The collective data tool was a self-made questionnaire with two parts. The first part comprised demographic characteristics, and the second part contained 20 items for the assessment of satisfaction with family doctor functions from different aspects. Multi-stage cluster sampling method was used to determine samples. Data were analyzed using SPSS software, and inferential statistical analysis was performed. Results: In this study, 100 cases were investigated. The majority of the study population were women, married, and aged between 30 and 39 years [mean= 30.42 (5.3) years]. Overall satisfaction averages were 9.47% very high, 20.04% high, 33.09% moderate, 15.12% low, and, 22.28% very low. In all the items, the majority of the participants did not report a high level of satisfaction. Conclusion: Allocating more resources and equipment, providing educational programs to improve physician and staff skills, holding training courses in villages to raise awareness about the goals of the family doctor, and careful monitoring of the quality of services provided by physicians will enhance the satisfaction level of people with this nationally important program.
