    BackgroundIndividuals who abuse prescription opioids often use leftover pills that were prescribed for friends or family members. Dental surgery has been identified as a common source of opioid prescriptions. We measured rates of used and unused opioids after dental surgery for a pilot program to promote safe drug disposal.MethodsWe conducted a randomized controlled trial of opioid use patterns among patients undergoing surgical tooth extraction at a university-affiliated oral surgery practice. The primary objective was to describe opioid prescribing and consumption patterns, with the number of unused opioid pills remaining on postoperative day 21 serving as the primary outcome. The secondary aim was to measure the effect of a behavioral intervention (informing patients of a pharmacy-based opioid disposal program) on the proportion of patients who disposed or reported intent to dispose of unused opioids. (NCT02814305) Results: We enrolled 79 patients, of whom 72 filled opioid prescriptions. On average, patients received 28 opioid pills and had 15 pills (54%) left over, for a total of 1010 unused pills among the cohort. The behavioral intervention was associated with a 22% absolute increase in the proportion of patients who disposed or reported intent to dispose of unused opioids (Fisher's exact p=0.11).ConclusionFifty-four percent of opioids prescribed in this pilot study were not used. The pharmacy-based drug disposal intervention showed a robust effect size but did not achieve statistical significance. Dentists and oral surgeons could potentially reduce opioid diversion by moderately reducing the quantity of opioid analgesics prescribed after surgery.Copyright © 2016.
