Potentially Preventable Hospitalization Among Adults with Hearing, Vision, and Dual Sensory Loss: A Case and Control Study

OBJECTIVE: To evaluate the risk of potentially preventable hospitalizations (PPHs) among adults with sensory loss. We hypothesized a greater PPH risk among people with a sensory loss (hearing, vision, and dual) compared with controls. PATIENTS AND METHODS: Using 2007-2016 Medicare fee-for-service claims, this retrospective, case-control study examined the risk of PPH among adults aged 65 years and older with hearing, vision, and dual sensory loss compared with their corresponding counterparts without sensory loss (between June 1, 2022, and February 1, 2023). We ran 3 step-in regression models for the 3 case and control cohorts examining PPH risk. Our generalized linear regression models controlled for age, sex, race, Elixhauser comorbidity count, rurality, neighborhood characteristics, and the number of primary care physicians and hospitals at the county level. RESULTS: People with vision (adjusted odds ratio [aOR], 1.21; 95% CI, 0.84-0.87) and dual sensory loss (aOR, 1.26; 95% CI, 1.14-1.40) showed a higher PPH risks than their corresponding controls. For people with hearing loss, our unadjusted models showed a higher PPH risk (OR, 1.40; 95% CI, 1.38-1.43) but after adjustment, hearing loss showed a protective association against PPH risk (OR, 0.85; 95% CI, 0.84-0.87). Moreover, in all models, annual wellness visits reduced the PPH risk by about half (eg, aOR, 0.54; 95% CI, 0.52-0.55), whereas living in disadvantaged neighborhood increased the PPH risk (eg, aOR, 1.13; 95% CI, 1.10-1.15) for cases and controls. CONCLUSION: People with vision and dual sensory loss were at greater PPH risk. This study has important health policy implications in reducing PPH and is indicative of a need for more incentivized and systematic approaches to facilitating the use of preventive care, particularly among older adults living in a disadvantaged neighborhood.
