SAPS 3, APACHE IV or GRACE: which score to choose for acute coronary syndrome patients in intensive care units?

CONTEXT AND OBJECTIVE Acute coronary syndromes (ACS) are a common cause of intensive care unit (ICU) admission. Specific prognostic scores have been developed and validated for ACS patients and, among them, GRACE (Global Registry of Acute Coronary Events) has had the best performance. However, intensive care clinicians generally use prognostic scores developed from heterogeneous populations of critically ill patients, such as APACHE IV (Acute Physiologic and Chronic Health Evaluation IV) and SAPS 3 (Simplified Acute Physiology Score 3).

Caution when using prognostic models: a prospective comparison of 3 recent prognostic models.

Purpose: Prognostic models have been developed to estimate mortality and to compare outcomes in different intensive care units. However, these models need to be validated before their use in different populations. In this study, we assessed the performance of 3 recently developed general prognostic models (Acute Physiologic and Chronic Health Evaluation [APACHE] IV, Simplified Acute Physiology Score [SAPS] 3 and Mortality Probability Model III [MPM(0)-III]) in a population admitted at 3 medical-surgical Brazilian intensive care units.

Use of the sequential organ failure assessment score as a severity score.

Objective: To evaluate whether the SOFA score can be used to develop a model to predict intensive care unit (ICU) mortality in different countries.

Design And Setting: Analysis of a prospectively collected database. Patients with ICU stay longer than 2 days were studied to develop a mortality prediction model based on measurements of organ dysfunction.
