Additional information
A total of 22,791 admissions were recorded in the 309 participating ICUs during the study period. For patients who were admitted more than once (n=1,455), only the first admission was included, giving 21,336 admitted patients. Patients who were <16 years of age (n=628), those without ICU admission or discharge data (n=1,074), and those with records that lacked an entry in the field “ICU outcome” (n=57) were excluded. The Basic SAPS 3 Cohort thus comprises 19,577 patients from 307 ICUs.For the development of a predictive model for hospital mortality as outcome, patients with a missing entry in the field of “vital status at hospital discharge” (n=2,540) or an entry of “still in the hospital” at the end of the follow-up period (n=253) were further excluded. The SAPS 3 Hospital Outcome Cohort thus comprises 16,784 patients from 303 ICUs.

Conditional information
Result interpretation
The SAPS 3 is an externally validated tool that accurately predicts ICU mortality. The score was evaluated and compared with the APACHE II and the SAPS 2. The performance of the SAPS 3 was similar to that of the APACHE II and the SAPSII
Discrimination of the SAPS 3 model showed c-statistics up to 0.89. The C-SAPS 3 score appeared to have the best calibration curve on visual inspection.
