Brief Summary:
A cohort study of women who deliver at select sites on randomly selected days in 2019 and 2020, and all confirmed COVID-19 infections among pregnant or immediately postpartum women in 2020. The study population includes approximately 24,400 deliveries on randomly selected days in 2019 and 2020, and an additional 1000-2100 confirmed COVID-19 infections among pregnant women or immediately postpartum.
Detailed Description:
This cohort study includes women who deliver at one of the MFMU Network hospitals on randomly selected days between March 1 and December 31, 2019 and March 1 and December 31, 2020 to evaluate the effect of a major public health crisis (COVID-19 pandemic) on maternal morbidity and mortality among pregnant and immediately postpartum women. This time period allows for calendar months in 2020 representing the key time period of the pandemic - after testing became available and changes were implemented in healthcare. Inclusion of the same months from 2019 represent the time period prior to the pandemic.
In addition to the cohort of women delivering at the selected MFMU Network sites on randomly selected days, all pregnant and immediately postpartum (within 6 weeks of delivery) with confirmed COVID-19 infection will be included in this study. Both women who were managed in-patient and those managed out-patient with COVID-19 infection will be included. All pregnant women with confirmed COVID-19 infection between March 1, 2020 and December 31, 2020 will be followed for maternal and neonatal outcomes through 6 weeks after delivery or surgical removal of the pregnancy.
Trained research staff will abstract data from the hospital's electronic medical records that meet eligibility criteria. Measures of healthcare and community-based modifications in response to the pandemic will be recorded by research staff. Individual participant data will include baseline data, COVID-19 exposure data, and maternal and neonatal outcome data.
The three primary objectives are 1) to evaluate whether pregnant or immediately postpartum women experience higher maternal morbidity and mortality during the COVID-19 pandemic than before the pandemic, 2) to evaluate whether women with COVID-19 infection, both in- and out-patient, have higher maternal morbidity and mortality than pregnant women without COVID-19 infection, and 3) to describe maternal and neonatal outcome data for all pregnant and immediately postpartum women with a confirmed COVID infection and contribute these data to an NICHD COVID-19 pregnancy registry. The primary endpoint, maternal morbidity and mortality, is defined as morbidity related to hypertensive disorders of pregnancy, morbidity related to postpartum hemorrhage, or morbidity related to infection during pregnancy or within six weeks (42 days) postpartum. For primary objective 1, the study has more than 90% power to show a 30% increase in the rate of the primary endpoint assuming the rate is at least 3% in calendar year 2019 and an alpha of 0.05 two-sided. For primary objective 2, the study will have more than 85% power to detect a 50% increase in the primary composite maternal morbidity endpoint, from 5% to 7.5% with an alpha=0.05 two sided if only 1,000 confirmed COVID-19 people are enrolled (80% power to detect a 30% increase in the primary composite if 2,200 confirmed COVID-19 people are enrolled).
For objective 1, analyses of the primary endpoint will consist of summarizing the proportions of participants with the primary endpoint for each calendar year cohort and calculating the corresponding relative risks with 95% confidence intervals. Individual morbidity composites (hypertensive disorders, postpartum hemorrhage, and infection) will also be compared by calendar year cohort. Outcome rates within 2019 will be graphically displayed and tested over time to ensure changes are not evident during the year that may explain differences between calendar years 2019 and 2020. For objective 2, analyses of the primary endpoint will consist of summarizing the proportions of participants with the primary endpoint among women with confirmed COVID-19 infection and those without confirmed infection, and calculating the corresponding relative risk with 95% confidence intervals.
