Use of Telehealth Services for Prenatal Care in Mississippi: Comparison of Pre-COVID-19 Pandemic and Pandemic Obstetric Management

BACKGROUND: The SARS-CoV-2 (COVID-19) pandemic resulted in major shifts in service delivery for patient care not involving COVID-19 illness. The preexisting telehealth infrastructure in Mississippi allowed the state to rapidly expand the scope of telehealth programs. Little research has been done to examine the use of telehealth during the COVID-19 pandemic and its impact on the delivery of care during pregnancy and outcomes associated with pregnancy. The objectives of this study are to (1) describe prenatal care practices during the height of the first wave of the COVID-19 pandemic, compared to the immediate prepandemic time period, and (2) explore maternal and birth outcomes during these time periods. METHODS: This study was conducted as a retrospective historical cohort study from medical records at one Maternal Care Level IV (Regional Perinatal Health Care Center) in Mississippi and its affiliated centers. The participant cohort was inclusive of women who received prenatal care prior to a single birth delivery between May 1, 2020, and January 31, 2021. The pandemic cohort was defined through the timeframe of the included participants' end-term prenatal care, with reference to the beginning of the COVID-19 pandemic. The prepandemic cohort received a majority of their prenatal care prior to the COVID-19 pandemic. RESULTS: There were 1,894 women included. Among them, 620 (32.77%) completed the majority of their end-term pregnancy in the pre-COVID-19 time period and 1,272 (67.23%) completed the end-term pregnancy during the pandemic. The odds ratio for patients from the pandemic cohort of scheduling telehealth visits compared to not scheduling telehealth visits is 8.19 (95% CI: 3.98, 16.86) times the odds ratio for patients from the prepandemic cohort. The pandemic exposure as well as infant's gestational age and very low birth weight (VLBW) show significant effects on the infant's living status in the univariate logistic regression. However, after controlling for the infant's gestational age and VLBW, we did not detect a significant effect of pandemic exposure. CONCLUSION: This study demonstrated a very small reliance of telehealth for the medical supervision of pregnant women during the COVID-19 pandemic. This is likely because of the essential physical examinations that occur in women who are considered to be at high risk for poor maternal and birth outcomes. Additional studies on the impact of COVID-19 infection on maternal and infant outcomes are also needed as there may be important risk factors not yet identified for poor maternal or birth outcomes.
