Why the study?
With decades of declining ICU mortality, it was hypothesized that the outcomes and distribution of diseases cared for in the ICU have changed.
Population
287,154 nonsurgical-critically ill adults from 237 U.S. ICUs
Comparison
Temporal trends across admission diagnoses from 2008 to 2016

Evolving ICU case mix without mortality gains highlights need for updated protocols; leaves open optimal resource allocation for emerging diagnoses.
Risk-adjusted ICU mortality rates for medically critically ill adults remained unchanged from 2008 to 2016, despite shifts in disease burden and decreased length of stay.
Ingraham et al. (2020) studied this question.
