The Simplified Acute Physiology Score III Is Superior to the Simplified Acute Physiology Score II and Acute Physiology and Chronic Health Evaluation II in Predicting Surgical and ICU Mortality in the “Oldest Old”

Table 3

Comparison of ICU mortality prediction models based on mean score and area under the receiver operator curve for 89 nonagenarians admitted to surgical ICU between 2000 and 2010.

Prediction models	Mortality group scores; (mean ± SD); 𝑁=14 (16%)	Survivor group scores; (mean ± SD); 𝑁=75 (84%)	Area under ROC curve; (95% CI)	𝑃 value
SAPS II	57.4±20.0	41.7±14.9	0.75 (0.60, 0.89)	𝑃<0.02
SAPS III	74.7±14.2	57.8±14.5	0.81 (0.70, 0.92)	𝑃<0.001
APACHE II	23.1±8.7	16.0±7.0	0.74 (0.59, 0.88)	𝑃<0.02

SD: Standard deviation, ROC: receiver operator curve, CI: Confidence Interval, 𝑁: number of patients, SAPS: standardized Acute Physiology Score, APACHE: Acute Physiology and Chronic Health Evaluation.
