Opioid disposal rates after spine surgery.

Abstract

Background: Diversion of prescription opioids pills is a significant contributor to opioid misuse and the opioid epidemic. The goal of this study was to determine the frequency and quantity of excess opioid pills among patients undergoing spine surgery. Further, we wanted to determine the frequency of appropriate opioid disposal.Methods: This was a prospective cohort study of patients undergoing elective spine surgery within a multi-hospital, academic, urban university health system enrolled in a text-messaging program used to track postoperative opioid disposal. Patients who self-reported discontinuation of opioid use but with leftover pills were contacted via telephone and surveyed on opioid disposal.Results: Of the 291 patients who enrolled in the text-messaging program, 192 (66%) patients reported discontinuing opioids within 3 months of surgery. Although 76 (40%) reported excess opioid pills after cessation of use, only 47 (62%) participated in the telephone survey regarding opioid disposal. The median number of leftover pills among these 47 patients was 5 (5, 15) and 64% had not disposed of their prescription.Conclusion: Among the 47 telephone survey participants, a persistent gap remained in postoperative opioid excess and improper disposal. Future efforts must focus on initiatives to improve opioid disposal rates to reduce the quantity of opioids at risk for diversion and to reduce excess prescribing.
