Health insurance deductions in Iranian public hospitals before and after the health transformation plan

Background: Developing countries, such as Iran, have been struggling with high rates of insurance deduction. As part of the Health Transformation Plan (HTP) in Iran, a new reference book was introduced to update the medical tariffs. This study aimed to compare the rates and extent of insurance deductions before and after HTP in Iran’s public hospitals. Methods: This was a quasi-experimental study. Overall, 400 medical bills were selected from Iran’s national Health Information System using multilevel random sampling before and after HTP implementation (2014 and 2017). Insurance deductions were divided into 5 groups: (1) diagnostic procedures, (2) medication and medical appliances, (3) accommodation and human capital provision, (4) surgery, and (5) other services. Using STATA Version 14.0, independent t test and Fisher’s exact test were used for data analysis. Significance level was set at 0.5. Results: There was a significant decrease in insurance deductions among Iran’s Health Insurance (HI) and Social Security Insurance (SSI). Accordingly, before HTP, the average amount of insurance deductions was 58.9% and 71.3% in HI and SSI, respectively. Moreover, there was a significant decline in all 5 groups between the pre- and postimplementation of HTP (p<0.05). Based on the results, hospitalization time (OR=2.31, 95% CI=1.9-3.2), patients in general hospitals (OR=1.49, 95% CI=1.4-2.7), coverage by SSI (OR=2.54, 95% CI=1.8-5.6), and having surgery (OR=3.5, 95% CI=2.0-7.3) increase the chance of insurance deduction significantly (p<0.05). Conclusion: Findings of this study showed that after HTP, insurance deductions were decreased significantly. The causes of this decline may be due to the range of services covered by public insurances, increase in insurance coverage, and improvement in health providers-insurance companies communication.
