26 Racial disparities in post-operative pain experience and treatment following cesarean birth

      Objective

      To evaluate racial/ethnic differences in post-operative pain experience and opioid medication use (morphine mg equivalent (MME)) in the first 24 hours following cesarean birth.

      Study Design

      This was a retrospective cohort study of women who underwent cesarean delivery at Meriter Hospital in Madison, WI between 01/01/2016 and 12/31/2017. A total of 2228 opioid-naive women were included. Pain assessment utilized all recorded pain scores (assessed on a 0-10 scale) in the first 24 hours post-delivery, which were abstracted manually. Linear regression was used to analyze the impact of race/ethnicity on pain and MME use.

      Results

      In multi-variate analysis non-Hispanic (NH) Black women reported higher average pain scores (coefficient: 0.629, 95% CI [0.414-0.844], p<0.001) (Table 1) than NH White women, but received similar quantities of MME (coefficient: 0.13 mg, 95% CI [-5.12-5.38], p=0.961) (Table 2). NH Asian women had similar reported average pain scores to NH White women (coefficient: -0.02, 95% CI [-0.218-0.179], p=0.845) (Table 1), but received less MME (coefficient: -7.44 mg 95% CI [-12.28- -2.59], p=0.003) (Table 2).
