Summary

Prenatal testing timing was largely maintained during the COVID-19 pandemic, with slight delays in some second-trimester screenings. Despite healthcare disruptions, essential prenatal screening remained a priority for expectant mothers and healthcare providers.

Area of Science:

  • Obstetrics and Gynecology
  • Public Health
  • Epidemiology

Background:

  • The COVID-19 pandemic significantly impacted healthcare systems globally.
  • Prenatal care delivery faced unprecedented challenges, necessitating an evaluation of its continuity and timing.

Purpose of the Study:

  • To assess changes in the timing of routine prenatal testing during the COVID-19 pandemic.
  • To compare prenatal testing schedules between pre-pandemic and early pandemic periods.

Main Methods:

  • A retrospective observational cohort study utilized claims and electronic health record data.
  • Data from Highmark, Penn Medicine, and Yale New Haven were analyzed for pre-pandemic (2018-2019) and early pandemic (2020) periods.
  • Primary outcomes included second-trimester fetal anatomy ultrasounds and gestational diabetes screening; first-trimester ultrasounds were a secondary outcome.

Main Results:

  • Mean gestational age for second-trimester anatomy ultrasounds slightly increased across all datasets during the pandemic.
  • A decrease in early (<20 weeks) anatomy ultrasounds was observed, but not at later gestations.
  • No consistent changes in gestational diabetes screening timing were found.
  • Significant reductions in first-trimester ultrasounds occurred at academic institutions.

Conclusions:

  • While some prenatal tests were performed later during the pandemic, overall timing remained appropriate.
  • Prenatal screening continued to be a priority, demonstrating resilience in care despite healthcare system disruptions.
