Patient Reported Opioid Consumption Following Outpatient Foot and Ankle Surgery

Abstract

Category: opioid consumption Introduction/Purpose: The expanding opioid crisis has forced orthopedic surgeons to evaluate their prescribing practices, yet there remains limited evidence to guide providers in achieving safe and effective postoperative analgesia. Our goal was to prospectively evaluate opioid consumption following outpatient foot and ankle surgery and determine predictors of increased narcotic usage. Methods: We prospectively enrolled adult patients scheduled for outpatient foot and ankle surgery and conducted phone and in- person interviews postoperatively to determine pain level, number of pills consumed, satisfaction with pain control, and whether other analgesic medication was used. Interviews were performed at four separate time points: 5 days, 10 days, 2 weeks, and 6 weeks following surgery. Additional data collected included age, gender, payer status, education level, preoperative pain level, procedure performed, whether opioid pain medication had been used by the patient in the 12 months preceding surgery, and the amount of narcotic prescribed postoperatively. Results: Complete data was available for 52 patients (median age, 42 years). The median number of opioids prescribed postoperatively was 45 pills (337.5 morphine milligram equivalents (MMEs)). A refill narcotic prescription was provided for 36.5% of patients. The number of opioid pills consumed following surgery ranged from 0 to 120 (median, 40 pills). Forty-six percent of patients had discontinued the use of opioids by post-op day 10 and 86.5% by post-op day 20. Increased pre-operative pain level (p = 0.02) and an increased quantity of pills prescribed at the first prescription (<0.0001) were significantly associated with increased narcotic consumption. Eighteen (39.1%) patients filled a narcotic prescription in the 12 months prior to surgery, however, narcotic use prior to surgery did not significantly increase total opioid consumption. Conclusion: We found that the median number of opioids consumed following outpatient foot and ankle surgery was 40 pills. Nearly 90% of patients had discontinued narcotic use by 20 days postoperatively. Pre-operative pain level and the number of pills provided at the first prescription were predictive of increased narcotic usage.
