Key result
The SAPS II score showed good discrimination for mortality (AUC 0.85; 95% CI 0.840-0.866; P<0.001) but significantly overestimated actual mortality (SMR 0.89; 95% CI 0.78-0.98).
Why the study?
Does the SAPS II system accurately predict hospital mortality in patients in major Croatian hospitals?
Population
2756 patients in five university hospitals and one general hospital in Croatia

Caution advised for individual predictions with SAPS II in Croatia; extends validation but leaves calibration open in this population.

Does the SAPS II system accurately predict hospital mortality in patients in major Croatian hospitals?
Effect estimate: AUC 0.85 (95% CI 0.840-0.866)
p-value: p=<0.001
The SAPS II score shows good discrimination but poor calibration (overestimates mortality) in Croatian hospital patients, suggesting caution when used at the individual level.
Deša et al. (2012) conducted an observational in Hospitalized patients (n=2,756). Simplified Acute Physiology Score II (SAPS II) was evaluated on Hospital mortality prediction (discrimination and calibration) (AUC 0.85, 95% CI 0.840-0.866, p=<0.001). The SAPS II score showed good discrimination for mortality (AUC 0.85; 95% CI 0.840-0.866; P<0.001) but significantly overestimated actual mortality (SMR 0.89; 95% CI 0.78-0.98).
