Washington State COVID-19 pregnancy collaborative

Principal Investigator(s):

Initiative-funded COVID-19 rapid response grantees report final results

The objective of this proposal was to investigate the effects of a highly communicable infectious disease leading to severe pneumonia and death (COVID-19) in pregnant women in Washington State. Pregnant women are typically a highly vulnerable group to pathogenic respiratory viruses and have the highest WHO priority for influenza vaccination in a pandemic.

The team’s central hypothesis was that COVID-19 infections in pregnancy increase the risk for spontaneous abortion, preterm birth, stillbirth, intrauterine growth restriction and mental health disorders in the mother. They conducted a multi-site prospective chart review of prenatal and neonatal medical records across the majority of health systems in Western Washington (6 hospitals/hospital systems, >20 investigators). Overall, the Washington State COVID-19 in Pregnancy Collaborative sites captured approximately 61% of deliveries in Washington State during the study period.

The team successfully collected data to establish a large, population-based registry in Washington State. Analyses have been completed of the sociodemographic and clinical outcomes of 240 pregnant patients who contracted COVID-19. Work remains ongoing to calculate infection rates, disease severity, co-morbidity, symptom length and possible vascular injury that could impair fetal growth.

The team will continue working toward research to determine how COVID-19 impacts maternal-child physical and mental health. Further grants have been applied and awarded from the Center of Disease Control, Royalty Research Fund and partnerships with Washington State Department of Health.
