Enhanced recovery after surgery (ERAS) is a multifaceted, standardized perioperative care protocol associated with improved surgical recovery. Its use has not been widely studied in obstetrics. Given the high rate of opioid dependence after cesarean delivery (CD), our aim was to evaluate the impact of an Enhanced Recovery for Obstetric Surgery (EROS) protocol on post-CD opioid use and perceived pain. EROS was implemented at Lehigh Valley Health Network (LVHN) 9/2018 (changes summarized in Figure 1). This retrospective cohort study compared post-CD opioid use between women undergoing CD before (7/1/17 – 6/30/18) and after (1/1/19 – 12/31/19) EROS implementation. Women with a significant surgical complication, history of chronic pain, current illicit drug use or current treatment for substance abuse disorder were excluded. A separate paired analysis compared outcomes of those delivering in both groups. Primary outcome was median total post-CD inpatient opioid use (morphine milligram equivalents; MME). Secondary outcomes included median discharge prescription MME, and mean pain scores on standardized assessment (10-point Likert scale). 1475 women in the pre-EROS group and 1546 women in the post-EROS group were identified. Median inpatient post-CD opioid MME and discharge MME were both significantly decreased post-EROS [75 (IQR 45-75) vs 30 (IQR 15-60) MME, p<0.001 and 900 (IQR 600-1125) vs 562.5 (IQR 360-750) MME, P<0.001, respectively], as were average pain score and mean highest pain score (3.5 vs 3.1 MME, p<0.001 and 7.3 vs 7.1 MME, p<0.003, respectively). Paired analysis of the 77 women who had a CD in both groups showed similar decreases in both opioid requirements and pain scores post-EROS. There was less variation in opioid use patterns post-EROS (Figure 2). Use of an Enhanced Recovery Protocol results in decreased post-cesarean delivery opioid use and improved pain perception. Given the scope of the opioid crisis, future studies should address whether use of this protocol can lead to decreased opioid dependence in this population.View Large Image Figure ViewerDownload Hi-res image Download (PPT)
