ABSTRACT
BACKGROUND: Having a potentially traumatic birth experience (PTBE) is a known risk factor for postpartum depression (PPD) and postpartum anxiety (PPA). PTBE-related PPA or PPD can peak long after six weeks postpartum, when typical screening for PPD and PPA typically occurs, leaving many of these individuals disconnected from care. Collaborative care models (CCMs) have been shown to reduce PPD and PPA via collaboration between care managers, obstetric clinicians, and mental health professionals. Whether participating in a CCM mitigates the risk of worsening PPD or PPA after PTBE is unknown.
OBJECTIVE: To examine trajectories of PPD and PPA among those who experienced a PTBE and participated in a CCM.
STUDY DESIGN: This secondary analysis of a prospective cohort study included people enrolled in COMPASS, a CCM program embedded within all Northwestern Medicine prenatal clinics. All pregnant or postpartum people with a history of a mental health conditions or current mental health symptoms during pregnancy or within a year postpartum are eligible for COMPASS referral. Those who enroll in COMPASS are screened every two to four weeks for depression and anxiety symptoms using the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7), respectively. For this secondary analysis, COMPASS participants were stratified into two groups based on whether they had a PTBE, defined as postpartum hemorrhage, maternal intensive care unit (ICU) admission, or preterm birth <35 weeks (the gestational age cut-off for required Neonatal Intensive Care Unit (NICU) admission at this medical center). PTBE was evaluated as a composite and as its individual subcomponents. The primary outcomes were worsening trajectories for PPD or PPA, defined by a score increase of ≥1 standard deviation on the PHQ-9 or GAD-7, respectively, on at least two assessments for up to one year postpartum. A propensity score was used in multivariable models to control for covariates that significantly differed in bivariable analysis.
RESULTS: Among 2,312 COMPASS participants, 413 (17.9%) had PTBE. Compared to those without a PTBE, those with PTBE were more likely to have a pregnancy conceived via IVF, public insurance, or be diagnosed with preexisting diabetes, preexisting hypertension, or obesity. Among 736 and 282 participants with at least two PPD and PPA assessments, 65 (2.8%) and 27 (1.2%) had worsening PPD or PPA trajectories, respectively. After using propensity scores to control for differences identified between groups, PTBE was not associated with worsening trajectories for PPD [aOR 0.92 (95% CI 0.36, 2.38)] or PPA [(aOR 0.64 (95% CI 0.12, 3.26)]. There was no association between individual conditions within the PTBE composite and worsening PPD or PPA trajectories.
CONCLUSIONS: Among those enrolled in COMPASS, worsening PPD or PPA trajectories were uncommon, and PTBE were not associated with worsening trajectories. Given the abundance of literature suggesting that PTBE are associated with worse PPD and PPA symptoms, these findings suggest that enrollment in a CCM may be associated with mitigation of the negative impact of PTBE.
