ABSTRACT
Introduction: Since the beginning of the pandemic, the Italian Obstetric Surveillance System (ItOSS) coordinated research activities to support health professionals and decision makers. The aim of this paper is to describe the results of the populationbased prospective study on SARS-CoV-2 infection among pregnant women during the first pandemic wave. Materials and methods: From the end of February 2020, ItOSS launched a prospective population-based cohort study enrolling all SARSCoV- 2 pregnant women admitted to any Italian hospital. Anamnestic and clinical information was collected in a structured form and entered in a web-based secure system by trained clinicians of any maternity unit.
ABSTRACT
The new coronavirus emergency spread to Italy when little was known about the infection's impact on mothers and newborns. This study aims to describe the extent to which clinical practice has protected childbirth physiology and preserved the mother-child bond during the first wave of the pandemic in Italy. A national population-based prospective cohort study was performed enrolling women with confirmed SARS-CoV-2 infection admitted for childbirth to any Italian hospital from 25 February to 31 July 2020. All cases were prospectively notified, and information on peripartum care (mother-newborn separation, skin-to-skin contact, breastfeeding, and rooming-in) and maternal and perinatal outcomes were collected in a structured form and entered in a web-based secure system. The paper describes a cohort of 525 SARS-CoV-2 positive women who gave birth. At hospital admission, 44.8% of the cohort was asymptomatic. At delivery, 51.9% of the mothers had a birth support person in the delivery room;the average caesarean section rate of 33.7% remained stable compared to the national figure. On average, 39.0% of mothers were separated from their newborns at birth, 26.6% practised skin-to-skin, 72.1% roomed in with their babies, and 79.6% of the infants received their mother's milk. The infants separated and not separated from their SARS-CoV-2 positive mothers both had good outcomes. At the beginning of the pandemic, childbirth raised awareness and concern due to limited available evidence and led to "better safe than sorry" care choices. An improvement of the peripartum care indicators was observed over time.
