Racial/Ethnic Disparities in Peripartum Pain Assessment and Management

This study was conducted to determine if there were racial/ethnic disparities in pain assessment and management from labor throughout the postpartum period. This was a retrospective cohort study of all births from January 2019 to December 2021 in a single urban, quaternary care hospital, excluding patients with hysterectomy, ICU stay, transfusion of more than 3 units of packed red blood cells, general anesthesia, or evidence of a substance abuse disorder. We characterized and compared patterns of antepartum and postpartum pain assessments, epidural use, pain scores, and postpartum pain management by racial/ethnic group with bivariable analyses. Multivariable regression was performed to test for an association between race/ethnicity and amount of opioid pain medication in milligram equivalent units, stratified by delivery mode. There were 18,085 births between 2019 and 2021 with available race/ethnicity data. Of these, 58.3% were white, 15.0% were Hispanic, 11.9% were Asian, 7.4% were Black, and the remaining 7.4% were classified as Other/Declined. There were no significant differences by race/ethnicity in the number of antepartum or postpartum pain assessments or the proportion of patients who received epidural analgesia. Black and Hispanic patients reported the highest maximum postpartum pain scores after vaginal and cesarean birth compared to white and Asian patients. However, Black and Hispanic patients received lower daily doses of opioid medications than white patients, regardless of delivery mode. After adjusting for patient factors and non-opioid medication dosages, all other racial/ethnic groups received less opioid medication than white patients. Inequities were found in postpartum pain treatment, including among patients reporting the highest pain levels.
