BACKGROUND: Postoperative opioids, intended for short-term analgesia, contribute to new persistent opioid use in 1%-7% of patients, adversely affecting outcomes. Oxycodone may carry higher risk than morphine, though long-term data are limited. This prospective comparative sequential cohort study assessed whether replacing from oxycodone with morphine as first-line opioid after orthopaedic surgery affected new persistent opioid use at 6 months and maintained analgesic equivalence.
METHODS: Patients ≥18 years undergoing orthopaedic surgery requiring ≥1 night hospitalization were enrolled April 2023 to January 2024.
PRIMARY OUTCOME: new persistent opioid use at 6 months, assessed by online survey.
SECONDARY OUTCOME: analgesic effectiveness assessed by pain at rest (NRS ≥ 4) at discharge and 6 months, and daily opioid use (oral morphine equivalents) during hospitalization.
RESULTS: Of 3675 eligible patients, 1894 (51.5%) completed the survey and were included (mean [SD] age 62.9 [13.1] year; 62.5% female). Among these, 1021 were in the morphine first-line opioid cohort and 873 in the oxycodone first-line opioid cohort. The proportion of new persistent opioid use at 6 months after surgery was 2.5% (morphine) vs. 2.6% (oxycodone) (p = .90). Pain at rest (NRS ≥ 4) was reported by 9.9% vs. 12.5% at discharge, and 19.3% vs. 19.7% at 6 months (morphine vs. oxycodone). Median (IQR) daily opioid dose during hospitalization was 12.3 (0-30) and 15 mg (0-30) (morphine vs. oxycodone). No significant differences were observed.
CONCLUSIONS: Replacing oxycodone with morphine as first-line opioid after orthopaedic surgery did not appear to reduce new persistent opioid use (NPOU) and provided comparable analgesia.
