Factores asociados a la evolución de la COVID-19 en mujeres embarazadas: un estudio poblacional brasileño

Autoría SCIMAGO INSTITUTIONS RANKINGS

RESUMEN

Objetivo:

Evaluar la evolución de la COVID-19 entre gestantes brasileñas, identificando predictores sociodemográficos y clínicos relacionados con el ingreso en unidad de cuidados intensivos y la muerte.

Método:

Estudio transversal, de base poblacional, realizado con una base de datos secundaria, a partir de datos del Sistema de Información de Vigilancia Epidemiológica de Influenza. Se realizó un análisis descriptivo, seguido de regresión lineal múltiple con respuesta de Poisson, adoptando una p crítica <0,05.

Resultados:

Se identificaron tasas de ingreso a cuidados intensivos del 28,2% y tasas de mortalidad del 9,5%. La región de residencia, el trimestre gestacional, el número de comorbilidades y los signos y síntomas respiratorios se asociaron con el riesgo de ingreso a cuidados intensivos. La edad mayor de 34 años, las comorbilidades, la saturación de oxígeno igual o inferior al 95%, el ingreso a cuidados intensivos y el soporte ventilatorio, sea invasivo o no, aumentaron el riesgo de muerte.

Conclusión:

Los predictores sociodemográficos y clínicos mostraron asociación con la hospitalización en cuidados intensivos y la muerte en gestantes con COVID-19.
