Factor/characteristicsPrevalence/rate or associatedStudies
Overall OUD prevalence6–50% (pooled mean: 8%)Multiple systematic reviews & meta-analyses [24, 25]
Patients at high risk for OUD23.5%Meta-analysis [25]; screening tools (screener and opioid assessment for patients with pain identified 20% as high-risk [11, 26])
Development of non-medical opioid use19% within 8 weeks of opioid prescriptionEarly follow-up data [11]
Chronic opioid use after diagnosis14% (majority were opioid-naive)Population-based studies [27]
Persistent postoperative opioid use33.3% overall (48.3% with prior exposure, 18.5% opioid-naive)Head and neck surgery cohort data [28]
Key risk factorsPrior opioid exposure, younger age, male gender, substance use history, anxiety, and financial distressMulti-study consensus [29, 30]
