Objective:
To decrease the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on the Mount Sinai Hospital's obstetric service, additional contact and respiratory precautions for patients and staff were implemented. Patients were allowed only one support person, SARS-CoV-2 tested on admission, and required to mask during hospitalization. Staff were required to wear masks and eye shields, gloves for all patient care, and gowns for care with SARS-CoV-2-infected patients. This study determined if the risk of endometritis/intra-amniotic infection (IAI) changed under the new pandemic precautions.
Study Design:
A single-center, historical cohort study via electronic medical record review compared singleton deliveries among patients who labored during the "pandemic period" (from March 1 through May 31, 2020) with those who labored during the "prepandemic period" (March 1 through May 31, 2019) to determine if the risk of endometritis/IAI differed. The analysis was done using logistic regression with inverse probability of treatment weighting (IPTW) to adjust for possible differences in obstetric practice and patient population between the two periods.
Results:
Four percent (53/1,318) of patients in the pandemic period and 5.1% (82/1,596) of patients in the prepandemic period were diagnosed with endometritis/IAI (p = 0.15). Compared with patients who delivered in the prepandemic period, those who delivered during the pandemic period had a higher body mass index at delivery (median: 28.36 [interquartile range, IQR: 25.70, 32.07] vs. 28.00 [IQR: 25.23, 31.50], p = 0.01) and experienced fewer digital exams (median: 4 [range: 1, 10] vs. 4 (range: 1, 19], p = 0.004), a practice not included in the SARS-CoV-2 prevention strategy. In multivariable logistic regression with IPTW adjusting for risk factors for endometritis/IAI, period of delivery was not associated with endometritis/IAI (odds ratio = 0.76, 95% confidence interval [0.52, 1.11], p = 0.15).
Conclusion:
The use of respiratory and contact precautions to limit the spread of SARS-CoV-2 was not associated with risk of endometritis/IAI.
Key Points:
· Pandemic infection control precautions were not associated with a decrease in endometritis/IAIs.. · The early months of the pandemic were associated with the performance of fewer digital cervical exams.. · The early months of the pandemic were associated with a higher BMI at delivery..
