Summary

Key Learning Points
1. Predictive scoring systems can use physiological, clinical and laboratory data to predict critical care patient mortality.
2. Their use extends to enabling standardisation of research cohorts, comparing and auditing critical care units and triaging critical care provision.
3. The most commonly used general scoring systems worldwide are APACHE (Acute Physiology and Chronic Health Evaluation) II and SOFA (Sequential Organ Failure Assessment) scores.
4. All systems need to be validated for calibration and discrimination, and have the potential to become less accurate over time.
5. No one system is better than any other – all have advantages and disadvantages.
