Category: Trauma; Ankle Introduction/Purpose: There has been significant scrutiny of physicians' opioid prescribing patterns for both operative and non- operative patients. Orthopaedic surgeons are the third highest group of opioid prescribers among physicians in the United States. The wide scope of orthopaedic procedures lends to the variability and difficulty in setting forth prescribing guidelines. Recent orthopedic literature has highlighted that orthopaedic surgeons are prescribing excess narcotic medication than is needed in common orthopaedic procedures. Ankle fractures make up about 9% of all fractures, which correlates to about 400,000 per year. The purpose of this study was to assess the amount of post-operative pain medication being prescribed and how much of that medication was being consumed in patients who underwent an open reduction internal fixation (ORIF) of an ankle fracture. Methods: We identified all patients that underwent a unilateral ORIF of a closed ankle fracture. We prospectively collected data on patients at the time of surgery. Patients were identified and enrolled in the study prior to their surgical procedure, where they were instructed to bring their pain medication bottle with them to their first post-operative visit. Patients were asked about the quantity of opioids consumed. At the twelve-week post-op, the American Orthopedic Foot and Ankle Score (AOFAS) was completed by the patient. We recorded the number, dosage, and formulation of opioid medication prescribed up to 90 days after surgery using the Pennsylvania Drug Monitoring Program (PDMP) website. Using opioid equianalgesic charts, we converted dosages of opioid to a morphine milligram equivalent (MEq) to standardize prescription amounts across all patients. Descriptive statistics were calculated and reported. Categorical data were compared using chi-square tests and quantitative data were compared using independent sample t-tests. Results: 75 patients were included in our study, 45 of which were female. The mean age of the patient was 46.7 years old with a range from 17-77 years old. On average, 400MEq were prescribed to the patient after surgery. Patients consumed an average of 258 MEq within the 2 weeks following surgery, which accounted for about 65% of the initial prescription. Thirty (13.3%) patients consumed their entire first prescription. Patients who consumed the full opioid prescription were 8.7 times more likely (95% CI 2.6, 29.3, X2(1)=14.1, pConclusion: We found the average patient consumes the equivalent of 34 pills of 5mg oxycodone after undergoing an open reduction internal fixation of an ankle fracture. Our providers over prescribed, on average, by 21 total pills. 9.3% of patients were still requiring narcotic pain medication ninety days post-operatively. Those patients who did not consume their first narcotic prescription were found to have statistically better functional outcome scores compared to those who did. Further studies should continue to assess patient characteristics, surgeon techniques, and prescribing habits to further improve post-operative pain control in patients undergoing open reduction internal fixation of ankle fractures. |
