Performance of maternal symptoms as a screening test to predict COVID-19 infection
Sensitivity: 34.4% (11/32)
Specificity: 96.1% (124/129)
Positive predictive value: 68.7% (11/16)
Negative predicative value: 85.5% (124/145)
Knowledge of asymptomatic COVID-19 positive patients would increase PPE use by 10%
All neonates born to COVID-19 positive mothers tested negative for the virus
In this study, 20% of women presenting to L&D were positive for COVID-19
66% of these women were asymptomatic
No neonates born to positive mothers tested positive
The authors make the following points based on these results
This approach ensures that SARS-CoV-2 positive mothers are accurately identified and triaged
Clinicians can monitor for the development of symptoms while these patients are admitted and allocate inpatient resources appropriately (chest imaging, supplemental oxygen, infectious disease consults) if a mother’s respiratory status changes secondary to COVID-19
On a system level, identifying COVID-19 positive mothers has a significant impact on rooming postpartum patients with/near one another and in ensuring the safe transfer between hospital units
