ObjectivesOpioid use disorder is extremely common. Many long-term opioid users will have their first exposure to opioids in hospitals. We aimed to compare long-term opioid use in patients who received fentanyl vs. morphine analgosedation and assess ICU related risk factors for long-term opioid use.DesignWe performed a post-hoc analysis of the Assessment of Opioid Administration to Lead to Analgesic Effects and Sedation in Intensive Care (ANALGESIC) cluster randomised crossover trial of fentanyl and morphine infusions for analgosedation in mechanically ventilated patients.SettingTwo mixed, adult, university affiliated intensive care units in Melbourne, Australia.ParticipantsAdult patients who were mechanically ventilated and received fentanyl or morphine for analgosedation in the ANALGESIC trial.Main Outcome MeasuresWe assessed discharge and long-term (90-365 days) opioid use in opioid-naïve patients at hospital admission according to the agent used for analgosedation.ResultsWe studied 477 patients (242 fentanyl and 235 morphine). There were no differences between discharge (16.5% vs. 14.0%, p = 0.45), 90-180 day post-discharge use (3.7% vs 2.1%, p = 0.30) or 180-365 day post-discharge use (3.4% vs 1.3%, p = 0.22) of opioids when comparing those patients who received fentanyl vs. those who received morphine. Surgical diagnosis and one chronic condition were associated with increased hospital discharge prescription of opioids, whereas increasing APACHE II score was associated with decreased discharge prescription. No ICU-related factors were associated with long-term opioid use.ConclusionsApproximately one in seven opioid-naïve patients who receive analgosedation for mechanical ventilation in ICU will be prescribed opioid medications at hospital discharge. There was no difference in discharge prescription or long-term use of opioids depending on whether fentanyl or morphine was used for analgosedation.Crown Copyright © 2023 Published by Elsevier B.V. on behalf of College of Intensive Care Medicine of Australia and New Zealand.
