Definitions and Denominators ICU Utilization: What Do the Numbers Really Tell Us?

This document summarizes a study on ICU utilization and outcomes in the United States from 2008 to 2019. The study found that while the number of hospitalizations decreased, the proportion of hospitalizations using ICU resources remained stable. The authors also noted a decline in hospital length of stay and mortality among ICU hospitalizations, suggesting improved care or potential over-utilization of ICU care. The study emphasizes the need for standardized definitions and metrics to accurately assess ICU utilization and calls for further research to optimize its use. [Extracted from the article]
