N2 - Objective. To examine the correlates and odds of receiving overlapping benzodiazepine and opioid prescriptions and whether co-prescription was associated with greater odds of falling or visiting the emergency department. Design. Cross-sectional study. Setting. A large private integrated health system and a Veterans Health Administration integrated health system. Subjects. Five hundred seventeen adults with musculoskeletal pain and current prescriptions for long-term opioid therapy. Methods. A multivariate logistic regression model examined correlates of having overlapping benzodiazepine and opioid prescriptions in the year before enrollment in the cross-sectional study. Negative binomial models analyzed the number of falls in the past three months and past-year emergency department visits. In addition to propensity score adjustment, models controlled for demographic characteristics, psychiatric diagnoses, medications, overall comorbidity score, and opioid morphine equivalent dose. Results. Twenty-five percent (N ¼ 127) of participants had co-occurring benzodiazepine and opioid prescriptions in the prior year. Odds of receiving a benzodiazepine prescription were significantly higher among patients with the following psychiatric diagnoses: anxiety disorder (adjusted odds ratio [AOR] ¼ 4.71, 95% confidence interval [CI] ¼ 2.67–8.32, P < 0.001), post-traumatic stress disorder (AOR ¼ 2.24, 95% CI ¼ 1.14–4.38, P ¼ 0.019), and bipolar disorder (AOR ¼ 3.82, 95% CI ¼ 1.49–9.81, P ¼ 0.005). Past-year overlapping benzodiazepine and opioid prescriptions were associated with adverse outcomes, including a greater number of falls (risk ratio [RR] ¼ 3.27, 95% CI ¼ 1.77–6.02, P ¼ 0.001) and emergency department visits (RR ¼ 1.66, 95% CI ¼ 1.08–2.53, P ¼ 0.0194). Conclusions. Among patients with chronic pain prescribed long-term opioid therapy, one-quarter of patients had co-occurring prescriptions for benzodiazepines, and dual use was associated with increased odds of falls and emergency department visits.
