ARTICLE HIGHLIGHTS
Research background

Few studies on acute gastrointestinal injury have been reported in critically ill patients with coronavirus disease 2019 (COVID-19).

Research motivation

This was the first study to investigate acute gastrointestinal injury (AGI) in critically ill patients with COVID-19.

Research objectives

To investigate the prevalence and outcomes of AGI in critically ill patients with COVID-19.

Research methods

In this retrospective study, the primary endpoints were the incidence of AGI and 28-d mortality.

Research results

The incidence of AGI was 86.7%, and hospital mortality was 48.2% in critically ill patients. Sequential organ failure assessment scores, white blood cell (WBC) counts, and duration of mechanical ventilation were risk factors for the development of AGI grade II and above.

Research conclusions

Patients with worse AGI grades had worse clinical severity variables, a higher incidence of septic shock, and higher hospital mortality.

Research perspectives

To our knowledge, this is the first study to investigate AGI in critically ill patients with COVID-19. The incidence of AGI was 86.7%, and hospital mortality was 48.2% in critically ill patients. Sequential organ failure assessment scores, WBC counts, and duration of mechanical ventilation were risk factors for the development of AGI grade II and above. Patients with worse AGI grades had worse clinical severity variables, a higher incidence of septic shock, and higher hospital mortality.
