Differences in opioid prescriptions by race among U.S. older adults with a hip fracture transitioning to community care

Abstract Background Appropriate pain management can facilitate rehabilitation after a hip fracture as patients transition back to the community setting. Differences in opioid prescribing by race may exist during this critical transition period. Methods We conducted a retrospective cohort study of older adult U.S. Medicare beneficiaries with a hip fracture to examine whether the receipt and dose of opioids differs between Black and White patients as they transitioned back to the community setting. We stratified beneficiaries by whether they received institutional post‐acute care (PAC). Outcomes were (1) receipt of an opioid and (2) opioid doses in the first 90 days in the community in milligram morphine equivalents (MMEs; also presented in mg oxycodone). We estimated relative rates and risk differences of opioid receipt and dose differences using Poisson and linear regression models, respectively, using the parametric g‐formula to standardize for age and sex. Results We identified 164,170 older adults with hip fracture (mean age = 82.7 years; 75% female; 72% with PAC; 46% with opioid use after fracture). Overall use of opioids in the community was similar between Black and white beneficiaries. Black beneficiaries had lower average doses in their first 90 days in both total cumulative doses (PAC group: 165 95% CI −264 to −69 fewer MMEs −248 mg oxycodone; no PAC: 167 95% CI −274 to −62 fewer MMEs −251 mg oxycodone) and average MME per days' supply of medication (PAC: −3.0 −4.6 to −1.4 fewer MMEs per day −4.5 mg oxycodone; no PAC: −4.7 −4.6 to −1.4 fewer MMEs per day −7.1 mg oxycodone). In secondary analyses, Asian beneficiaries experienced the greatest differences (e.g., 617–653 fewer cumulative mg oxycodone). Conclusion Racial differences exist in pain management for Medicare beneficiaries after a hip fracture. Future work should examine whether these differences result in disparities in short‐ and long‐term health outcomes.
