Impact of Replacing Fentanyl With Hydromorphone as the First-Line Postoperative Opioid Among Patients Undergoing Outpatient Cancer Surgery

• Purpose: In response to a nationwide fentanyl shortage, our institution assessed whether changing our first-line postoperative intravenous opioid from fentanyl to hydromorphone impacted patient outcomes. The primary research aim was to evaluate the association between first-line opioid and rapidity of recovery. Design: The study team retrospectively obtained data on all consecutive patients extracted from the electronic medical record. The rapidity of recovery was defined as the time from entry into the post- anesthesia care unit to the transition to Phase 2 for ambulatory extended recovery patients and as the length of total postanesthesia care unit stay for outpatients. Methods: Following intent-to-treat-principles, we tested the association between study period and rapidity of recovery (a priori clinically meaningful difference: 20 minutes) using multivariable linear regression, adjusting for anesthesia type (general vs monitored anesthesia care), American Society of Anesthesiologst physical status (ASA) score (1-2 vs 3-4), age, service, robotic procedure, and surgery start time. Findings: Ambulatory extended recovery patients treated in the hydromorphone period had, on average, a 0.25 minute (95% confidence interval [CI] -6.5, 7.0), nonstatistically significant (P P > .9) longer time to transition. For outpatient procedures, those who received hydromorphone had, on average, 8.5-minute longer stays (95% CI 3.7-13, P < .001). Although we saw statistical evidence of an increased risk of resurgery associated with receiving hydromorphone (0.5%; 95% CI -0.1%, 1.0%; P = .039 on univariate analysis), the size of the estimate is clinically and biologically implausible and is most likely a chance finding related either to multiple testing or confounding. Conclusions: The multidisciplinary team concluded that the increase in postoperative length of stay associated with hydromorphone was not clinically significant and the decrease waste of prefilled syringes outweighed the small potential increased risk of resurgery compared to the shorter-acting fentanyl. We will therefore use hydromorphone moving forward.
