This study aimed to determine whether opioid use, with or without benzodiazepine use, is associated with increased all-cause mortality in COPD patients.Methods: This prospective cohort study included adults aged ≥ 20 years with COPD from the US National Health and Nutrition Examination Survey 2007– 2012. The primary outcome was all-cause mortality, which were obtained through linkage to registries. Weighted Cox proportional hazards regression models were used to evaluate hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause mortality. Additionally, subgroup and sensitivity analyses were used to evaluate the robustness of our findings.Results: This study enrolled 811 participants, representing 10.84 million COPD individuals in the United States (mean [standard error] age, 58.7 [0.6] years). During a median follow-up of 9.6 years, mortality rates were 57.8 per 1000 person-years in patients using only opioids, 41.3 per 1000 person-years in patients using only benzodiazepines, 45.7 per 1000 person-years in patients using both opioids and benzodiazepines, and 27.0 per 1000 person-years in patients using neither. In the fully adjusted model, COPD patients prescribed both opioids and benzodiazepines (HR: 1.76; 95% CI: 1.11– 2.78) and those prescribed opioids only (HR: 1.68; 95% CI: 1.13– 2.49) had significantly higher all-cause mortality compared to non-users. After adjusting for propensity scores, the mortality risk for opioid-only users slightly increased (HR: 1.87; 95% CI: 1.25– 2.81). Further, subgroup analysis revealed an elevated mortality risk in patients over 60 years receiving coprescriptions or opioids only, but not in younger participants. In contrast, benzodiazepine-only users aged 60 or younger showed increased mortality risk.Conclusion: Opioid use, with or without benzodiazepine use, was associated with higher mortality in COPD patients over 60, while benzodiazepine-only use was associated with higher mortality aged 60 or younger.Keywords: opioid, benzodiazepine, chronic obstructive pulmonary disease, mortality, national health and nutrition examination survey, NHANES
