Background: There has been little-to-no evidence to support the use of opioid analgesia as a treatment modality for osteoarthritis (OA). Chronic opioid use has been associated with peri-operative and post-operative complications with joint reconstruction. The purpose of this study is to compare opioid-prescribing habits for OA between orthopedic and non-orthopedic physicians to identify encounters that increase opioid exposure.
Methods: A retrospective chart review was performed on opioid-naive adult patients with outpatient opioid prescriptions for OA at a single academic institution between 2013 and 2018. Patients with prior surgery or opioid prescriptions were excluded. Independent t-tests and analysis of variance were used to compare prescription characteristics among providers.
Results: A total of 9625 opioid prescriptions were identified. Non-orthopedic providers account for 92% of prescriptions vs 8% by orthopedic surgeons. The greatest number of prescriptions is written by Internal Medicine (37.1%) and Family Medicine physicians (36.0%). Non-orthopedic physicians prescribe a greater number of prescriptions per patient, dosages, and refills (P < .001 for all). Non-orthopedic encounters are associated with increased risk for prescription dosages ≥50 MME/d (odds ratio 5.81, 95% confidence interval 4.35-7.81, P < .001) and 90 MME/d (odds ratio 18.2, 95% confidence interval 4.43-35.70, P < .001).
Conclusion: The majority of opioid prescriptions for OA are written by non-orthopedic providers, with higher prescription rates, dosages, and more refills than orthopedic surgeons. OA is a common condition that will benefit from multi-disciplinary awareness to minimize unnecessary opioid exposure and reduce potential complications with joint arthroplasty.
