Applying a health equity lens to the perioperative anesthetic management for coronary artery bypass grafting.

Background: Disparities in healthcare based on race, ethnicity, and socioeconomic status (SES) remain a public health crisis, especially in perioperative anesthetic management. This study applies a health equity lens to intraoperative pain and postoperative nausea and vomiting (PONV) for patients undergoing coronary artery bypass grafting (CABG).

Methods: This retrospective cohort study included 1404 adult patients who underwent coronary artery bypass grafting (CABG) between 2017 and 2022 at a single, multi-site, academic healthcare system. The primary outcomes were PONV as well as moderate-to-severe post-operative pain. Secondary outcomes were administration of prophylactic antiemetics, compliance with guideline-recommended antiemetic prophylaxis, and opioid morphine milligram equivalents (MME) administered intraoperatively. Independent variables included patient race and ethnicity, healthcare payor type, and community-level SES (using Area Deprivation Index [ADI]). Multivariable logistic regression models that controlled for relevant covariates were utilized.

Results: The findings showed no significant disparities in experiencing PONV, post-operative pain, or receiving high opioid MME based on race, ethnicity, payor type, and ADI. There were also no differences in the receipt of antiemetics nor compliance with guideline-recommended antiemetic prophylaxis.

Conclusions: Our study did not find racial, ethnic, or SES disparities in intraoperative anesthetic pain management, postoperative pain, nor PONV management. Applying a health equity lens to quality outcomes during the perioperative period is necessary to ensure equitable care among diverse populations.
