- Abstract
Background: Although opioids are initiated on hospital discharge in millions of older adults each year, there are no studies examining patient‐ and prescribing‐related risk factors for opioid‐related adverse drug events (ADEs) after hospital discharge among medical patients. Methods: A retrospective cohort study of a national sample of Medicare beneficiaries aged 65 years and older, hospitalized for a medical reason, with at least one claim for an opioid within 2 days of hospital discharge. We excluded patients receiving hospice care and patients admitted from or discharged to a facility. We used administrative billing codes and medication claims to define potential opioid‐related ADEs within 30 days of hospital discharge, and competing risks regression to identify risk factors for these events. Results: Among 22,879 medical hospitalizations (median age 74, 36.9% female) with an opioid claim within 2 days of hospital discharge, a potential opioid‐related ADE occurred in 1604 (7.0%). Independent risk factors included age of 80 years and older (HR 1.18, 95% CI 1.05–1.33); clinical conditions, including kidney disease (HR 1.22, 95% CI 1.08–1.37), dementia/delirium (HR 1.38, 95% CI 1.22–1.56), anxiety disorder (HR 1.20, 95% CI 1.06–1.36), opioid use disorder (HR 1.20, 95% CI 1.03–1.39), intestinal disorders (HR 1.31, 95% CI 1.15–1.49), pancreaticobiliary disorders (HR 1.32, 95% CI 1.09–1.61), and musculoskeletal and nervous system injuries (HR 1.35, 95% CI 1.17–1.54); red flags for opioid misuse (HR 1.37, 95% CI 1.04–1.80); opioid use in the 30 days before hospitalization (HR 1.20, 95% CI 1.08–1.34); and prescription of long‐acting opioids (HR 1.34, 95% CI 1.06–1.70). Conclusions: Potential opioid‐related ADEs occurred within 30 days of hospital discharge in 7.0% of older adults discharged from a medical hospitalization with an opioid prescription. Identified risk factors can be used to inform physician decision‐making, conversations with older adults about risk, and development and targeting of harm reduction strategies.
