Association between Cognitive Impairment and Repeat Fractures in Medicare Beneficiaries Recently Hospitalized for Hip Fracture

Research output: Contribution to journalArticlepeer-review


Background: Repeat fractures contribute substantially to fracture incidents in older adults. We examined the association between cognitive impairment and re-fractures during the first 90 days after older adults with hip fractures were discharged home from a skilled nursing facility rehabilitation short stay. Methods: Multilevel binary logistic regression was used to analyze 100% of U.S. national postacute-care fee-for-service Medicare beneficiaries who had a hospital admission for hip fracture from January 1, 2018, to July 31, 2018; were admitted for a skilled nursing facility stay within 30 days of hospital discharge; and were discharged to the community after a short stay. Our primary outcome was rehospitalization for any re-fractures within 90 days of skilled nursing facility discharge. Cognitive status assessed at skilled nursing facility admission or before discharge was classified as either intact or having mild or moderate/severe impairment. Results: In 29 558 beneficiaries with hip fracture, odds of any re-fracture were higher in those with minor (odds ratio: 1.48; 95% confidence interval: 1.19-1.85; p <. 01) and moderate/major cognitive impairment (odds ratio: 1.42; 95% confidence interval: 1.07-1.89; p =. 0149) than in those classified as intact. Conclusions: Beneficiaries with cognitive impairment were more likely than their counterparts with no cognitive impairment to experience re-fractures. Community-dwelling older adults with minor cognitive impairment may experience a higher likelihood of experiencing a repeat fracture leading to rehospitalization.
