We examined 10-year trends in potentially preventable hospitalizations (PPH) in Korea, comparing individuals with and without disabilities and assessing age-specific patterns.METHODS: Using National Health Information Database claims data (2010\u20132019), we established a fixed cohort of newly registered individuals with disabilities and control subjects statistically matched (1:1.5) at baseline. Annual PPH rates among patients with each condition were calculated and age- and sex-standardized according to Organization for Economic Cooperation and Development Health Care Quality Indicators definitions. Trends and annual percent changes (APCs) were analyzed by disability status and age group (non-older: 30\u201364; older adults: \u226565 years).RESULTS: Between 2010 and 2019, PPH rates declined significantly in both groups. Among individuals with disabilities, the steepest decline was observed for hypertension (APC, \u221215.7%; 95% confidence interval [CI], \u221217.7 to \u221213.7), whereas congestive heart failure showed the largest reduction among individuals without disabilities (APC, \u22127.8%; 95% CI, \u221210.8 to \u22124.7). Declines were generally greater among non-older adults aged 30\u201364 years, regardless of disability status. The disparity between disability and non-disability groups narrowed over the decade, primarily due to larger improvements among non-older adults. Older adults with disabilities consistently exhibited the highest PPH rates for most conditions, whereas younger individuals with disabilities had the highest rates for diabetes.CONCLUSIONS: PPH rates declined over the decade among both individuals with and without disabilities, particularly for hypertension and among non-older adults. However, older adults with disabilities remain at elevated risk, underscoring the need for targeted strategies to improve access to community-based primary care.<\/jats:p>","DOI":"10.4178\/epih.e2026012","type":"journal-article","created":{"date-parts":[[2026,2,27]],"date-time":"2026-02-27T05:45:56Z","timestamp":1772171156000},"page":"e2026012","update-policy":"https:\/\/doi.org\/10.4178\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Age-
