Disparities in the provision of perinatal care based on patient race in the United States.

Background: In the United States, there are significant health inequities in perinatal care. This study examined differences in perinatal care provided to women based on the birthing person's designated race, within a large and diverse cohort of women. Methods: This retrospective electronic medical record review identified patients receiving perinatal care within a large hospital system between January 2012 and September 2018 and examined associations between maternal designated race/ethnicity (Hispanic or non‐Hispanic [NH] Black, Asian or White) and various provider treatment decisions. Results: The study sample (N = 7056) was comprised of 36% Hispanic, 34% NH White, 21% NH Black, and 4% NH Asian women, aged 29.7 ± 6.3 years; 53% of the sample had private insurance, and 45% had Medicaid. Few differences by race were seen in perinatal care based on guidelines or expert recommendations (nondiscretionary care). Discretionary care, however, varied by race: Compared with NH White women, NH Black women were less likely to receive a prenatal depression screen (OR 0.8 [95% CI: 0.7, 0.9]) and more likely to have a urine drug test when denying drug use (OR 1.6 [95% CI 1.3, 2.0]), whereas Hispanic (OR 0.6 [95% CI: 0.5, 0.8]) and NH Asian (0.4 [95% CI 0.2, 0.9]) women were less likely to have a urine drug test completed when denying drug use. Discussion: Perinatal care differs by maternal race/ethnicity, particularly when guidelines or expert recommendations are absent. Greater efforts need to be made to identify and mitigate providers' implicit and explicit biases; expanded professional guidelines may offer some protections against inequitable, discretionary care.
