Study objectives: Prescription use and misuse of opioids are linked to greater sleep disturbance. However, there are limited data on the prevalence of sedative-hypnotic medication use among persons who use opioids. Therefore, this study examined whether past-year sedative-hypnotic use among persons who used/misused opioids was higher than among individuals who did not use opioids.
Methods: Data were acquired from the US National Survey on Drug Use and Health for 2015-2018. Use of a sedative benzodiazepine (temazepam, flurazepam, triazolam) or a Z-drug (eszopiclone, zaleplon, zolpidem) was examined in relation to use/misuse of an opioid within the past year. Logistic regression models estimated the associations between opioids and sedative-hypnotics using inverse probability of treatment weighting. A secondary machine learning analysis tested 6 binary classifiers to predict sedative-hypnotic use based on opioid use/misuse and other covariates.
Results: Of 171,766 respondents, 24% used a prescription opioid whereas 3.6% misused an opioid in the past year. Among those who used a prescription opioid, 1.9% received a sedative benzodiazepine and 9% received a Z-drug during the same time frame. Use of an opioid was associated with greater odds of sedative benzodiazepine use (odds ratio, 4.4; 95% confidence interval, 3.61-5.4) and Z-drug use (odds ratio, 3.8; 95% confidence interval, 3.51-4.09), and stronger associations were noted for misuse of an opioid. Machine learning models accurately classified sedative-hypnotic medication use for > 70% of respondents based on opioid use/misuse.
Conclusions: Sedative-hypnotic use is common among persons who use opioids, which is of concern given the elevated mortality risk with concurrent use of these substances.
