Prescription Opioid Use Disorder Among Adults Reporting Prescription Opioid Use With or Without Misuse in the United States.

Objective: We examined prescription related opioid use disorder (POUD) prevalence, individual symptoms, severity, characteristics, and treatment by prescription opioid misuse status among adults with prescription opioid use.
Methods: Cross-sectional study using nationally representative data from 47,291 adults aged ≥18 years who participated in the 2021 National Survey on Drug Use and Health. Past-year POUD used DSM-5 criteria.
Results: Among US adults with past-year prescription opioid use, 12.1% (95% CI, 11.1%-13.1%) misused prescription opioids, and 7.0% (95% CI, 6.2%-8.9%) had POUD. Among adults with POUD, 62.0% (95% CI, 56.7%-67.2%) reported no prescription opioid misuse, including 49.1% (95% CI, 43.5%-54.7%) with mild POUD, 11.0% (95% CI, 6.5%-15.4%) with moderate POUD, and 1.9% (95% CI, 0.6%-3.2%) with severe POUD. Prevalence of POUD was 4.5 times higher (prevalence ratio = 4.5, 95% CI, 3.6-5.6) among those reporting prescription opioid misuse (22.0%, 95% CI, 18.6%-25.8%) than those reporting use without misuse (4.9%, 95% CI, 4.2%-5.7%). Among adults reporting prescription opioid use without misuse, high POUD prevalence was found for those with ≥3 emergency department visits (16.4%, 95% CI, 11.5%-23.0%), heroin use/use disorder (17.1%, 95% CI, 5.2%-43.8%), prescription sedative/ tranquilizer use disorder (36.2%, 95% CI, 23.6%-51.1%), and prescription stimulant use disorder (21.8%, 95% CI, 11.0%-38.7%).
Conclusions: Moderate-to-severe POUD is more frequent among adults who report misusing prescription opioids. However, 62% of adults with POUD do not report prescription opioid misuse, suggesting that adults who are treated with prescription opioids and report no misuse could be at risk for developing POUD. Results highlight the need to screen for and treat POUD among adults taking prescription opioids regardless of whether they report prescription opioid misuse.
