May support VA ICU risk adjustment; confirms strong discrimination but leaves external validation open.
Render et al. (2008) conducted an observational in Intensive care unit (ICU) admissions (n=118,204). VA ICU severity measure vs. National Surgical Quality Improvement Performance metrics was evaluated on Predictive validity (C statistic) (C statistic 0.887). The updated Veterans Affairs ICU severity model demonstrated strong predictive validity for ICU outcomes (C statistic = 0.887).
