Adverse Perinatal Outcomes in a Large US Birth Cohort During the COVID-19 Pandemic : Adverse Perinatal Outcomes During COVID-19

ABSTRACT:

Objective

To investigate whether coronavirus disease 2019 (COVID-19) is associated with adverse perinatal outcomes in a large national dataset and to examine rates of adverse outcomes during the pandemic compared to pre-pandemic period.

Methods

This observational cohort study included 683,905 patients, between the ages of 12-50, hospitalized for childbirth and abortion between January 1, 2019 and May 31, 2021. During the pre-pandemic period, 271,444 women were hospitalized for childbirth. During the pandemic, 308,532 women were hospitalized for childbirth and 2,708 had COVID-19. Associations between COVID-19 and in-hospital adverse perinatal outcomes were examined using propensity score-adjusted logistic regression.

Results

Compared to women without COVID-19, women with COVID-19 were more likely to experience both early and late preterm birth (aOR 1.38 [95% CI 1.1-1.7], aOR 1.62 [95% CI 1.3-1.7], respectively), preeclampsia (aOR 1.2 [95% CI 1.0-1.4]), disseminated intravascular coagulopathy (DIC) (aOR 1.57 [95% CI 1.1-2.2]), pulmonary edema (aOR 2.7 [95% CI 1.1- 6.3]), and need for mechanical ventilation (aOR 8.1 [95% CI 3.8-17.3]). There was no significant difference in the prevalence of stillbirth among women with (n= 16 / 2,708) and without (n= 174 / 39,562) COVID-19, p=0.257. There were no differences in adverse outcomes among women who delivered during the pandemic versus pre-pandemic period. Combined in-hospital mortality was significantly higher for women with COVID-19 (147 [95% CI 3.0 -292] vs 2.5 [95% CI 0-7.5] deaths per 100,000 women). Women diagnosed with COVID-19 within 30 days prior to hospitalization were more likely to experience early preterm birth, placental abruption, and mechanical ventilation, compared to women diagnosed with COVID-19 > 30 days prior to hospitalization for childbirth (4.0% vs. 2.4% for early preterm birth, aOR 1.7 [95% CI 1.1-2.7]; 2.2% vs. 1.2% for placental abruption, aOR 1.86 [95% CI 1.0 - 3.4]); 0.9% vs. 0.1% for mechanical ventilation, aOR 13.7 [95% CI 1.8-107.2])).

Conclusion

Women with COVID-19 had a higher prevalence of adverse perinatal outcomes and increased in-hospital mortality, with highest risk occurring when diagnosis was within 30 days of hospitalization, raising the possibility of a high-risk period.

Project description:ObjectivesThe COVID-19 pandemic has caused considerable stress throughout the world. Little is known about how postpartum women who gave birth during the early months of the pandemic were impacted. The purpose of this study was to explore and describe the associations between potential risk, protective factors, and psychological distress among postpartum women who gave birth during the early months of the COVID-19 pandemic.MethodsPostpartum women over the age of 18 years who gave birth in the US hospitals between March and July of 2020 and spoke English completed a survey about their experiences. Demographic and health variables were measured via self-report. Stress was measured using the Perceived Stress Scale-10. Mastery was measured with the Pearlin Mastery Scale. Resilience was measured with the Connor-Davidson Resilience Scale-2.ResultsThis study included 885 women. Participants had higher stress and lower resilience relative to pre-pandemic norms. Participants had high levels of depression, anxiety, and stress. Women who had an infant admitted to the neonatal intensive care unit had more stress. Income, full-time employment, and partnered relationships were associated with lower stress. Resilience and mastery were related to lower stress, depression, and anxiety. Black, Indigenous, or People of Color women showed higher stress and lower resiliency. Single women were likely to report lower levels of mastery than partnered women.ConclusionStress, depression, and anxiety were high in postpartum women in this study. Income, partnered relationships, and employment security, along with protective traits such as mastery and resilience, may reduce the impact of stress on postpartum women in a pandemic. Care models should be modified to support women during a pandemic. Health disparities exist in postpartum stress. Future interventions should focus on building resiliency and mastery and ensuring appropriate resources are available to postpartum women in a pandemic.
