Enhanced Recovery after Surgery Protocol to Improve Racial and Ethnic Disparities in Postcesarean Pain Management.

Objective: The objective of this study was to assess the efficacy of an enhanced recovery after surgery (ERAS) protocol and determine its effect on racial/ethnic disparities in postcesarean pain management. Study

Design: We performed an institutional review board-approved retrospective cohort study of scheduled cesarean deliveries before and after ERAS implementation at a single urban academic institution. Pre-ERAS, all analgesic medications were given postoperatively on patient request. The ERAS protocol included preoperative acetaminophen and celecoxib. Postoperatively, patients received scheduled nonsteroidal anti-inflammatory drugs and acetaminophen. Oral oxycodone was available as needed, and opioid patient-controlled analgesia was eliminated from the standard order set. The primary outcome was total opioid use in the first 48 hours after cesarean, pre- and post-ERAS, reported in total milliequivalents of intravenous morphine (MME). A secondary analysis of opioid use and pain scores by racial groups was also performed. Chi-square, independent t-tests, analysis of variance, Mann-Whitney U, and Kruskal-Wallis tests were used depending on variable and data normality.

Results: Pre-ERAS and post-ERAS groups included 100 women each. Post-ERAS, total opioid use in 48 hours was less (40.8 vs. 8.6 MME, p < 0.001) and visual analog scale (VAS) pain scores were lower on postoperative day 1 (POD1) and 2 (POD2) (POD1 maximum at rest: 6.7 vs. 5.3, p < 0.001). Pre-ERAS pain scores differed by race with non-Hispanic Black (NHB) patients reporting the highest mean and max VAS pain scores POD1 and POD2 (POD1, maximum VAS at rest: NHB-7.4, non-Hispanic White-6.6, Hispanic-5.8, Asian-4.4, p = 0.006). Post-ERAS, there were no differences in postoperative pain scores between groups with movement on POD1 and POD2.

Conclusion: A standardized ERAS protocol for postcesarean pain decreases opioid use and may improve some racial disparities in postcesarean pain control. Key points: · ERAS protocols improve postoperative pain control and lower postoperative opioid use.. · Studies show that there are racial and ethnic disparities in postpartum pain control.. · Protocols standardize care and may decrease the effects of provider implicit bias..
