Opioid Medication Disposal Among Patients Following Hand Surgery

BACKGROUND: Despite increased public awareness to dispose of unused narcotics, opioids prescribed postoperatively are retained, which may lead to drug diversion and abuse. This study assessed retention of unused opioids among hand surgery patients and describes disposal methods and barriers. METHODS: Participants undergoing hand surgery were given an opioid disposal information sheet preoperatively (N = 222) and surveyed postoperatively to assess disposal or retention of unused opioids, disposal methods, and barriers to disposal. A binomial logistic regression was conducted to assess whether age, sex, pain intensity, and/or the type of procedure were predictors of opioid disposal. RESULTS: There were 171 patients included in the analysis (n = 51 excluded; finished prescription or continued opioid use for pain control). Unused opioids were retained by 134 patients (78%) and disposal was reported by 37 patients (22%). Common disposal methods included returning opioids to a pharmacy (49%) or mixing them with an unwanted substance (24%). Reasons for retention included potential future use (54%), inconvenient disposal methods (21%), or keeping an unfilled prescription (9%). None of the patient factors analyzed (age, sex, type of procedure performed, or pain score) were predictors of disposal of unused narcotics (P > .05). CONCLUSIONS: Most patients undergoing hand surgery retained prescribed opioids for future use or due to impractical disposal methods. The most common disposal methods included returning narcotics to a pharmacy or mixing opioids with unwanted substances. Identifying predictors of disposal may provide important information when developing strategies to increase opioid disposal.
