    Study ObjectiveThe primary aim of this study is to understand how intraoperative medication administration patterns change in response to ERAS® protocol implementation for patients who underwent laparoscopic donor nephrectomy.DesignSingle-center, retrospective analysis of laparoscopic donor nephrectomy patients.SettingLarge tertiary academic medical center.PatientsWe divided all cases of laparoscopic donor nephrectomies (n = 929) over seven years into three approximately equal time periods: Pre-ERAS 1 (n = 317), Pre-ERAS 2 (n = 297) and Post-ERAS (n = 315).MeasurementsWe examined patient demographics, intraoperative opioid and non-opioid pain adjuvant administration, Post Anesthesia Recovery Unit (PACU) pain scores and opioid use as well as PACU and hospital lengths of stay (LOS).Main ResultsSegmented regression analysis of interrupted time series was utilized to evaluate the association of ERAS protocol implementation with the amount of intraoperative opioid and non-opioid pain adjuvant use. In adherence to our institutional ERAS protocol, there was a significant reduction in intraoperative fentanyl use after ERAS protocol of -70.2μg (95% CI -106.0, -34.2, p < 0.001) and a significant increase in intraoperative hydromorphone use of 0.47 mg (95% CI 0.284, 0.655, p < 0.001). However, in contrary to our ERAS protocol, we found no significant change in odds of receiving IV acetaminophen OR 1.31 (95% CI 0.450, 3.76, p = 0.613) or IV ketorolac OR 1.65 (95% CI 0.804, 3.41, p = 0.172) after ERAS protocol implementation. We found a significant reduction in PACU opioid use of -9.68 Morphine Milligram Equivalents (MME) (95% CI -17.1, -2.31, p = 0.010) but no significant change in PACU initial pain score, PACU LOS and hospital LOS.ConclusionsWe examined intraoperative practice pattern changes by anesthesiologists in response to ERAS protocol implementation for laparoscopic donor nephrectomies. Our results suggest that there was a variable uptake of recommendations from ERAS protocol. While ERAS protocols are often studied as a bundle of best practice recommendations, understanding the variability of provider adherence represents an important future research direction for the ERAS initiative.Copyright © 2022 Elsevier Inc.
