Trends in postpartum mental health care before and during COVID-19.

ABSTRACT

OBJECTIVE: To assess the impact of COVID-19 on trends in postpartum mental health diagnoses and utilization of psychotherapy and prescription drug treatment. DATA SOURCES Data were obtained from a large, national health insurance claims database that tracks individuals longitudinally. STUDY DESIGN: We used interrupted time series models to examine changes in trends of postpartum mental health diagnoses before and during the COVID-19 pandemic and t-tests to examine differences in treatment. DATA EXTRACTION METHODS: We used billing codes to identify individuals who received mental health-related diagnoses and treatment in the first 90 days after a birth hospitalization. We excluded individuals diagnosed with schizophrenia or bipolar disorder and those with an unknown payer at delivery. PRINCIPAL FINDINGS: Compared to the pre-pandemic period, the trend in new postpartum mental health diagnoses increased significantly in the post-COVID-19 period (0.06 percentage points [95%CI 0.01, 0.11]). Over 12 months, the percentage of new diagnoses was 5.0% greater relative to what would be expected in absence of COVID-19. The percentage of diagnosed individuals who did not receive treatment increased from 50.4% to 52.7% (p = 0.003). CONCLUSIONS: Findings point to an urgent need to improve screening and treatment pathways for perinatal individuals in the wake of COVID-19.
