Descripción de la aplicación de screening universal para SARS-CoV-2 en mujeres embarazadas que ingresan para interrupción en Hospital de Carabineros – Santiago de Chile

Abstract

Introduction and objectives: Severe Acute Respiratory Syndrome Coronavirus (SARSCoV-2) is a highly contagious disease that can be transmitted by asymptomatic patients. Therefore, is of interest to determine the prevalence of SARS-Cov-2 infection in pregnant patients entering for interruption. Methods: A descriptive, retrospective analysis was performed in the Obstetrics and Gynecology Service of the Hospital de Carabineros de Chile between May 15 and June 30, 2020. Pregnant women who entered for interruption of their pregnancy and who were given the SARS-CoV-2 PCR exam were included. A survey of signs and symptoms suggestive of the disease was applied. Results: There were 73 pregnancy interruptions, 72 of them were tested by SARS-CoV-2 PCR exam. Among these patients, 65 (90.3%) resulted negative, 5 (6.9%), were positive and 2 (2.8%) were indeterminate; indeterminate results were considered positive, so the prevalence of positivity was 9.5%. Of these patients only 1 had symptoms suggestive of the disease, all the others (6) were asymptomatic, and remained so throughout the hospitalization. Conclusion: Conducting the PCR test for SARS-CoV-2 for all pregnant women entering a Gynecology and Obstetrics service helps to identify asymptomatic patients infected with the virus. As a survey of signs and symptoms cannot identify positive patiens, it is necessary to consider conducting universal screeing in hospital admission protocols throughout our country.
