Association between maternity care practitioner type and postpartum depression screening.

BACKGROUND

Postpartum depression (PPD) is increasingly common in the United States and poses a significant threat to maternal and neonatal health. Universal screening for postpartum depression is recommended by numerous organizations, including the American College of Obstetricians and Gynecologists, but is not achieved in practice.

METHODS

A cross-sectional, weighted, state-representative study of California residents who gave birth in 2016 using the Listening to Mothers in California 2018 data set. Primary exposure was type of maternity care professional providing care during pregnancy, and the primary outcome was PPD screening. The secondary exposure was self-reported depression or anxiety during pregnancy, and the secondary outcome was attending a postpartum office visit. Bivariate analyses were conducted using Rao-Scott chi-square tests, and multivariate analyses were conducted using logistic regression.

RESULTS

Compared to participants cared for by obstetricians, participants cared for by midwives had 2.6 times the odds of reporting being screened for PPD after controlling for covariates (95% CI = 1.5, 4.4). Receiving care from any other practitioner type compared with an obstetrician was not associated with a different rate of postpartum depression screening. Reporting depression or anxiety during pregnancy was associated with 0.7 times the odds (95% CI = 0.5, 1.0) of returning for postpartum care after controlling for covariates.

CONCLUSIONS

Being cared for by a midwife during pregnancy increases the likelihood of being screened for postpartum depression. In addition, even perfectly implemented universal screening will miss a vulnerable sector of the population that is at high risk for postpartum depression and is less likely to return for postpartum care.
