Timing and causes of death in severe COVID-19 patients.

Background: Previous studies reporting the causes of death in patients with severe COVID-19 have provided conflicting results. The objective of this study was to describe the causes and timing of death in patients with severe COVID-19 admitted to the intensive care unit (ICU).

Methods: We performed a retrospective study in eight ICUs across seven French hospitals.

Increased susceptibility to intensive care unit-acquired pneumonia in severe COVID-19 patients: a multicentre retrospective cohort study.

Background: The aim of this study is to determine whether severe COVID-19 patients harbour a higher risk of ICU-acquired pneumonia.

Methods: This retrospective multicentre cohort study comprised all consecutive patients admitted to seven ICUs for severe COVID-19 pneumonia during the first COVID-19 surge in France. Inclusion criteria were laboratory-confirmed SARS-CoV-2 infection and requirement for invasive mechanical ventilation for 48 h or more.
