Investigating the Effect of Having Health Insurance on the Utilization of Outpatient Services Provided by Physicians Based on the Data of the Utilization of Health Services Survey

One of the most important measures to ensure achieving Universal Health Coverage (UHC) is expanding health insurance coverage to all population. Accordingly, the present study was conducted with the aim of investigating the effect of having health insurance on the utilization of outpatient services provided by physicians using the data of the utilization of health services survey (2015).

This study is a secondary analysis of the utilization of health services survey data that was conducted in two groups of the insured and uninsured to examine the differences between these two groups in outpatient healthcare utilization provided by physicians. The variables were insurance status as an independent variable and the number of physician visit as a dependent variable. This analysis was disaggregated by place of residence and income.

The visit per capita for outpatient services was lower in all uninsured groups. The visit per capita in insured people was almost two times more than that of uninsured individuals, which was 4.25 and 2.61 among insured and uninsured individuals, respectively. Therefore, the lack of basic health insurance decreased the utilization of outpatient services by 50 percent. General physician visits per capita for insured people living in urban and rural areas were 11.2 and 0.35, respectively.

Based on the results of this study, the visit per capita is directly related to the insurance status of the individuals. Therefore, it is necessary to ensure the equity in utilization of outpatient services provided by the physicians among various groups of population.
