Background and purpose: Although, economically, referral systems make utilization of health facilities at different levels sound, in many countries caretakers often bypass primary care facilities that are regularly costlier for caretakers and health care systems. The main objective of the current study was to assess the utilization of hospital services with more emphasis on economic point of view. 

Materials and methods: The present study was a facility-based cross-sectional study. A researcher developed questionnaire was used to collect the data. The samples were randomly selected and interviewed on their consent. SPSS Software was also used to analyze the collected data through Chi-2, correlation, and t-test.

Results: Just 29.4 percent of the attendees to the hospital were carrying out a referral slip from their family medicine. Five variables including type of care, type of attending, appointment arrangement, satisfaction with family medicine, and vising family medicine were statistically analyzed and found significantly related to carrying referral slip.

Conclusion: Because of dysfunction of referral system, Iran’s health care system was found to be far from achieving economic advantages of a referral based DHS. It is actually an inappropriate use of limited health resources in a country like Iran that seriously suffers from shortage of financial and health system resources. This is likely due to deficiencies in the components of its referral system, therefore, a full revision of current reforms and appropriate remedies for deficiencies in the components of referral system was found to be in top priority in Iran.
