SARS-CoV-2 testing and clinical outcomes in a Texas tertiary care center labor and delivery unit

Our hospital adopted universal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing for labor and delivery patients in April 2020. The primary aim of this study was to determine the number of subjects from April 1, 2020, to July 31, 2020, who had laboratory-confirmed SARS-CoV-2 infection, and the secondary aims were to report demographic and clinical data for subjects with and without SARS-CoV-2 infection and the time from SARS-CoV-2 test collection to result for tests administered in the hospital. A total of 898 subjects had either vaginal or cesarean deliveries with a gestational age of >20 weeks during the study period. Of this group, 746 subjects underwent SARS-CoV-2 testing, and 16 had a positive test result. Four of the 16 subjects with laboratory-confirmed SARS-CoV-2 infection had documented symptoms at the time of admission. The difference in cohort size was too large to make a meaningful statistical comparison in demographic and clinical data between those with positive vs negative SARS-CoV-2 test results. The median time from SARS-CoV-2 test collection to result decreased from 239 minutes in April 2020 to 119 minutes in July 2020. Universal SARS-CoV-2 testing revealed a 2.1% positivity rate during our study period.
