From: Critical care among newborns with and without a COVID-19 diagnosis, May 2020–February 2022
Panel a is the relative risk for Level II or higher nursery admission. COVID-19 coronavirus disease 2019, PHD Premier Healthcare Database Special COVID-19 release, CI confidence interval, adjusted RR adjusted risk ratio, uRR unadjusted risk ratio. *Gestational age strata were chosen to reflect the critical threshold at which the majority of newborns would not routinely require admission to a higher-level nursery after birth for prematurity (35 gestational weeks). †Pre-delta: May 2020–May 2021; Delta: June–November 2021; Omicron: December 2021–February 2022. §Premier Healthcare Database, 523 hospitals with delivery hospitalizations. **Adjusted for hospital to account for within-facility correlation, provider region, and race and ethnicity. Panel b is the relative risk for ventilation support. COVID-19 coronavirus disease 2019, PHD Premier Healthcare Database Special COVID-19 release, IV invasive ventilation support, NIV non-invasive ventilation support, CI confidence interval, adjusted RR adjusted risk ratio, uRR unadjusted risk ratio. *Gestational age strata were chosen to reflect the critical threshold at which the majority of infants would not routinely receive respiratory support (32 gestational weeks). †Pre-delta: May 2020–May 2021; Delta: June–November 2021; Omicron: December 2021–February 2022. §Premier Healthcare Database, 523 hospitals with delivery hospitalizations. **Adjusted for hospital to account for within-facility correlation, provider region, and race and ethnicity.
