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.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
