Background: Pain is common among patients with cardiopulmonary conditions; however, there are increasing concerns, but limited research, regarding use of opioids for pain in patients with noncancer conditions. Objective: To compare patterns of opioid prescribing among older adults reporting pain with cardiopulmonary conditions and/or cancer. Design: Observational study using data from the Surveillance, Epidemiology, and End Results-Medicare Health Outcomes Survey resource linked to Medicare Part D prescription claims. Setting/Subjects: We identified patients who self-reported moderate-to-severe pain interference with daily activities. Patients were stratified by (1) self-reported history of cardiopulmonary conditions; (2) were within five years of cancer diagnosis; (3) had both conditions; or (4) neither. Measurements: We characterized opioid prescribing within 30 days of survey and one-year follow-up using logistic regression and Cox proportional hazard time-to-event analyses. Results: Of 10,516 patients with moderate-to-severe pain (1758 cardiopulmonary conditions, 3383 cancer, 2861 both, 2514 neither), 46% were aged ≥75 years, 65% were non-Hispanic white, and 10% non-Hispanic black. At survey, 1627 (15.5%) received opioids. Adjusted proportions of opioid use were lower for patients with cardiopulmonary conditions only (14%) compared with cancer only (17%; p < 0.001) and both conditions (17%; p < 0.001) but higher than patients with neither condition (13.1%; p < 0.001). There was no difference in time to initiation of opioids at follow-up among patients with cardiopulmonary conditions only, relative to cancer only (adjusted hazard ratio 1.03; 95% confidence interval 0.88-1.21). Conclusions: Opioid use is lower among patients with pain and cardiopulmonary conditions relative to patients with cancer. Findings emphasize the importance of pain assessment and management for patients with cardiopulmonary conditions.
