Abstract

Abstract: Objectives: This study aimed to explore the association of visual, hearing, or dual sensory impairment with healthcare use and costs. Study design: This is a cohort study. Methods: These research data were from the China Health and Retirement Longitudinal Study spanning 2011–2018 and included 8982 community-dwelling middle-aged and older adults (aged ≥45 years at baseline). Sensory impairment was measured according to self-reported assessment of visual and hearing functions, and healthcare use and costs were ascertained via self-report. The associations of sensory impairment with healthcare use and costs were estimated using the mixed-effects regression models. Results: Of the 8982 respondents, 4346 (48.39%) were females and their mean (standard deviation) age at baseline was 57.03 (8.26) years. Individuals with hearing impairment (HI) only, visual impairment (VI) only, and dual sensory impairment (DSI) were all at significantly higher risks of healthcare use and catastrophic health expenditure than those without sensory impairment (all P < 0.05), except that VI only non-significantly prolonged inpatient days. Compared with no impairment, DSI was associated with increases in outpatient (β = 50.67, 95% confidence interval [CI] = 17.47–83.86) and inpatient out-of-pocket costs (β = 40.35, 95% CI = 5.94–74.76), while VI only or HI only did not show significant effects. Further stratification analyses indicated that the associations between sensory impairment and outpatient use were more pronounced among males than among females but that age group did not moderate the associations with any healthcare outcomes. Conclusions: HI and VI were independently and together associated with higher risks of healthcare use and catastrophic health expenditure. Dual sensory impairment was the only category consistently associated with increased outpatient and inpatient costs.
