Abstract

Objectives: To estimate the prevalence of diagnosed traumatic brain injury (TBI) in individuals hospitalized with hip fracture and examine its association with all-cause mortality.

Design: Nested cohort study.

Setting: National sample of Medicare beneficiaries from 2006 to 2010.

Participants: Beneficiaries aged 65 and older hospitalized with hip fracture.

Measurements: TBI at the time of hip fracture was defined using International Classification of Diseases, Ninth Revision, Clinical Modification codes. The main outcome was all-cause mortality during follow-up.

Results: Prevalence of TBI in individuals with hip fracture was 2.7%. Absolute risk of mortality attributable to TBI in individuals with hip fracture was 15/100 person-years. TBI was significantly associated with risk of death in multivariable analysis (hazard ratio=1.24, 95% confidence interval=1.14-1.35).

Conclusion: TBI was associated with greater risk of mortality in individuals with hip fracture. Practitioners should consider evaluating for presence of TBI in this vulnerable population. J Am Geriatr Soc 67:124-127, 2019.

Keywords: Medicare; hip fracture; mortality; traumatic brain injury.
