Introduction: Concurrent opioid and benzodiazepine use ("double-threat") and double-threat and muscle relaxant use ("triple-threat") are postulated to increase morbidity versus opioids alone. Study objectives were to measure association between double- and triple-threat exposure and hospitalizations in a validated, nationally representative database of the United States. Methods: A retrospective cohort study was conducted using the 2013 and 2014 Medical Expenditure Panel Survey (MEPS) longitudinal dataset and affiliated Prescribed Medicines Files. ⋯ Compared to nonusers, double-threat patients increased hospitalization probability with ORs of 5.71 (95% CI: 5.69-5.72) in 2013, 11.47 (95% CI: 11.44-11.49) in 2014, and 5.59 (95% CI: 5.57-5.60) in the longitudinal analysis. Conclusion: Concurrent opioid and benzodiazepine use and opioid, benzodiazepine, and muscle relaxant use were associated with increased hospitalization likelihood. Amplified efforts in surveillance, prescribing, monitoring, and deprescribing for concurrent opioid, benzodiazepine, and muscle relaxant use are needed to reduce this public health concern.
