Comparative assessment of mortality risk factors between admission and follow-up models among patients hospitalized with COVID-19.

ABSTRACT:

Objectives

This study aimed to compare differences in mortality risk factors between admission and follow-up incorporated models.

Methods

A retrospective cohort study of 524 patients with confirmed COVID-19 infection admitted to a tertiary medical center in São Paulo, Brazil from 13 March to 30 April 2020. Data were collected on admission, and the third, eighth and fourteenth days of hospitalization. The hazard ratio (HR) was calculated and 28-day in-hospital mortality risk factors were compared between admission and follow-up models using a time-dependent Cox regression model.

Results

Of 524 patients, 50.4% needed mechanical ventilation. The 28-day mortality rate was 32.8%. Compared with follow-up, admission models under-estimated the mortality HR for peripheral oxyg
