Antimicrobial use in patients with end-of-life status in intensive care units: A systematic review and meta-analysis.

Objectives: Advances in critical care have increased antimicrobial use in intensive care units (ICUs), often extending to end-of-life patients without clear clinical benefit. This systematic review and meta-analysis investigated antimicrobial use in critically ill ICU patients with end-of-life care status. Methods: A comprehensive search of Medline (PubMed) and Embase identified articles published from January 2000 through August 2023. Interventional and observational studies focusing on antimicrobial use for critically ill ICU patients with end-of-life status were included. Study types, demographics, clinical characteristics, and antimicrobial use (i.e., continuation or discontinuation) were extracted. A meta-analysis was conducted to estimate the proportion of antimicrobial use, with subgroup analyses by region and national income status. Results: =99.7%, P
