Socioeconomic determinants of out-of-pocket pharmaceutical expenditure among middle-aged and elderly adults based on the China Health and Retirement Longitudinal Survey.

ABSTRACT:

Objective

Out-of-pocket pharmaceutical expenditure (OOPPE) is a considerable burden for middle-aged and elderly adults due to their high prevalence of diseases, insufficient income and absence of medical insurance in China. The objective of this study was to assess the determinants of OOPPE among Chinese middle-aged and elderly adults.

Methods

This is a cross-sectional study based on the China Health and Retirement Longitudinal Survey conducted in 2015. The Andersen behavioural health model was used to select the factors. Binary multivariable logistic and generalised linear regressions were both applied to examine the determinants of OOPPE.

Results

Of the respondents, 15.28%, 5.20% and 51.35% reported an OOPPE for outpatient services, inpatient services and self-medication, respectively. The OOPPE for outpatient services, inpatient services and self-medication was US$6.66, US$17.93 and US$15.32, respectively. Increased age significantly influenced the likelihood of OOPPE, and older people (aged >65 years) had lower OOPPE for outpatient services. Having health insurance significantly reduced the likelihood of OOPPE for outpatient and inpatient services but increased OOPPE for self-medication. In general, compared with the low-income group, higher income groups had a significantly lower likelihood of having an OOPPE, and when they did the amounts were less. Generally, middle-aged and elderly people with poor self-reported health status, limitation of daily activities, and critical or chronic diseases had a significantly higher likelihood of having an OOPPE and at a significantly higher amount.

Conclusion

Policy-making efforts should focus on reducing self-medication OOPPE and alleviating its associated socioeconomic determinants to ease the economic burden of diseases among middle-aged and elderly adults in China.
