Catastrophic Health Expenditure before and after of the Implementation of Health Sector Evolution Plan in Iran.

Introduction: One of the fundamental goals of health transportation plan (HTP) in Iran is to improve household's financial protection against catastrophic health expenditures (CHE). The aim of this study was to calculate the percentage of catastrophic health expenditures after implementing the plan and compare it with CHE before the plan for the same households. Methods: Data were collected through face-to-face interviews for 400 households. The CHE was calculated using the WHO approach, and relationships between CHE and the variables (having member ≥65 years old, having member ≤5 years old, having disabled member, economic status, health insurance status, dentistry services usage, and inpatient and outpatient services usage) were examined by the Fisher's exact test. Moreover, the impacts of the variables on CHE were assessed by logistic regression model. Stata version 15 was used for data analyses. Results: The exposure of the households to CHE increased from 8.3% in 2011 to 14.2% in 2020, and percentage of the impoverished households due to health expenditures in 2020 was more than that of the 2011 (4.3% vs 7.5%). The economic status, having members ≥65 years, and using dental and inpatient services were the key factors determining the CHE. The most important determinant affecting the exposure to CHE was dental services utilization in 2011 (92.64) and 2020 (122.68). Conclusion: The results showed a negative incremental change for the households facing CHE in this period. The dental and inpatient services need to be more widely covered by basic health insurance and households having members ≥65 years along with the poor households should be exempted from paying some of the healthcare expenditures for improving their financial protection against CHE.
