Impact of prefecture-level intensive care unit congestion on mortality in severe COVID-19 patients: a retrospective observational study in Japan.

ABSTRACT:

Background

The COVID-19 pandemic has placed unprecedented pressure on global healthcare systems, severely affecting the intensive care unit (ICU) capacity. Therefore, this study explored the association between prefecture-level ICU congestion and COVID-19 mortality in each prefecture of Japan.

Methods

This retrospective study analyzed data from the CRoss Icu Searchable Information System, covering all patients with COVID-19 who underwent mechanical ventilation with clearly documented initiation and cessation dates between January 1, 2020, and March 31, 2023.

Prefecture-level ICU c
