Abstract
Background: Geriatric hip fractures are common and important sentinel events regarding bone health. Although dual x-ray absorptiometry (DEXA) scans are a standard method for determining bone density, differences in use among various race/ethnic groups around the time of hip fracture may reveal disparities within the healthcare system.
Methods: The 2014 to 2016 Medicare Standard Analytic Files PearlDiver data set was used to identify geriatric patients sustaining hip fracture. From that cohort, those who had a DEXA scan before or after their fracture were defined. For the defined cohorts, patient age, sex, Elixhauser Comorbidity Index, race/ethnicity, and income (based on zip code) were defined and compared with univariate and multivariate analyses.
Results: Of 58,099 hip fracture patients, only 19.8% had had a DEXA scan before fracture and 3.9% of the remaining group had the DEXA scan after fracture. Of the hip fracture population, 91.0% identified as White and 9.0% as non-White (Native American, Black, Hispanic, Asian, or Other). Before hip fracture, controlling for other variables and compared with White patients, all non-White categories were at lesser odds of having had the DEXA scan. After hip fracture, Black, Hispanic, and other patients were also at lesser odds of having the DEXA scan.
Discussion: Using a large Medicare data set, controlling for patient age, sex, Elixhauser Comorbidity Index, and income marker, this study revealed disparities in DEXA scan utilization across race/ethnic groups before and after presenting with a hip fragility fracture. Identification of such disparities highlights the needs for improved medical access and care for this at-risk hip fracture population.
