Households catastrophic health expenditure among older people with noncommunicable diseases: A cross-sectional study from Iran.

BACKGROUND AND AIMS: Noncommunicable diseases are one of the main difficulties faced by older adults in many countries. The study aimed to investigate the households' catastrophic health expenditure (CHE) among older people with noncommunicable diseases.

METHODS: This cross-sectional study was conducted between October and December 2022 in Semnan, Iran, with the participation of 400 older individuals suffering from diabetes and hypertension. The Content Validity Ratio (which is calculated based on necessity criterion) and Content Validity Index (which calculated based on relevance, transparency, and simplicity criteria) values of 0.94 and 0.89, respectively, confirmed the content validity of the researcher-made questionnaire. The occurrence of CHE was estimated using the World Health Organization's rule of "allocating at least 40% of non-food household costs to healthcare." Due to the qualitative nature of the data, the χ 2 test was utilized to assess the statistical association between demographic and background variables and occurrence of CHE.

RESULTS: Older people with diabetes and hypertension had an annual direct medical costs of $821 averagely, which includes 9.7% for diagnosis, 23.9% for doctor visits, and 66.4% for treatment. Direct medical costs account for around 0.26 of nonfood costs, with 12.5% of seniors facing high medical charges. Age, marital status, type of basic health insurance, diabetes, the time elapsed since initial diabetes diagnosis, the severity of diabetes complications, and the development of diabetes-related visual impairments, are associated with CHE ( p  < 0.05).

CONCLUSION: While the prevalence of CHE among elderly individuals with diabetes and hypertension is reasonably manageable, targeted promotional efforts are still necessary to protect those at high risk.
