Association Between Number of In-Person Health Care Visits and SARS-CoV-2 Infection in Obstetrical Patients

Category:

Topic:

  • A nested case-control study among obstetrical patients delivering at four hospitals in Boston found that there was no meaningful difference between the number of in-person visits for case patients with SARS-CoV-2 versus controls (mean 3.3 visits versus 3.1). All patients in the study were tested for SARS-CoV-2 on admission.  Cases were matched with up to 5 controls on gestational age, race/ethnicity, insurance type, and SARS-CoV-2 incidence in the patient’s zip code of residence (n=2,968 deliveries). Results were adjusted for age, BMI, and essential worker occupation, with imputation for missing variables.
