Surgery Prescription Opioid Misuse and Diversion in US Adults and Associated Risk Factors.

INTRODUCTION: To justify a practice change, it is critical to determine if opioids prescribed after surgery, surgery prescription (Rx) opioids, are in fact associated with opioid misuse and diversion. Currently, there is only limited data to support this assumption. METHODS: We administered a 40-question survey to US adults (18+) who had received a surgery Rx opioid within the last 5 y on Amazon Mechanical Turk, an online crowdsourcing worksite. Incidence and risk factors for surgery Rx opioid misuse, self-reported taking of surgery Rx opioids in a way other than instructed by a provider, and diversion, self-reported having one's surgery Rx opioids shared, sold, or stolen, were analyzed. The government validated Opioid Risk Tool (ORT) was used. RESULTS: A total of 966 participants from all 50 states met inclusion: 52% were male, 43% were aged 30-39 y, and 79% self-identified as white. Overall, 34% (n = 333) of respondents reported misusing their surgery Rx opioids and risk factors included working in healthcare, scoring high on the ORT, experiencing an elevated mood with opioids, refilling a Rx, and keeping leftover pills. A total of 22% (n = 212) reported diverting their surgery Rx opioids, and risk factors included working in healthcare, scoring high on the ORT, undergoing plastic surgery, refilling a Rx, and keeping leftover pills. CONCLUSIONS: Rates of surgery Rx opioid misuse and diversion in the US may be as high as one in three and one in five adults, respectively. Efforts to improve leftover pill disposal and risk stratification for prescribing patterns may help to mitigate risk.
