Dementia Diagnosis Not Associated With Readmission After Skilled Nursing Rehabilitation

An observational study in the Journal of the American Geriatrics Society examined hospital readmission after short rehabilitative skilled nursing home stays lasting less than 100 days. Researchers linked Health and Retirement Study data to Medicare claims from 2000–2019 and used event-level regression analyses to assess factors associated with 30-day hospital readmission after discharge to the community.

Among 4,527 discharges, 714 were followed by hospital readmission within 30 days (15.8%). A dementia diagnosis identified through Medicare claims, present in 42.2% of the population, was not associated with readmission. Hospital or emergency department use in the preceding year and higher Charlson comorbidity scores were associated with higher odds of readmission. Female sex, being married, and residence in the Midwest or Western United States were associated with lower odds.

The findings highlight prior acute care use, comorbidity burden, and social circumstances as considerations for discharge planning. The authors suggest that a documented dementia diagnosis might prompt enhanced discharge support, but the abstract does not establish that such support explains the findings. The observational design cannot establish causality, and the available abstract provides neither adjusted effect estimates nor confidence intervals. Dementia ascertainment relied on claims rather than a reported clinical assessment.
