The Comparison of Reliabilities of Nutritional Risk Scoring and Physiological Severity Score in Critical Care Patients

Objective: APACHE II is most commonly used severity prognostic model in ICU patients. Nutritional risk screening 2002 (NRS-2002) score is widely suggested for screening of nutritional risk in general hospitalized patients. In this study, we aimed to compare the reliability of NRS-2002 with APACHE II on outcome in critical care patients. Material and Methods: Discrimination and calibration characteristics of the scoring systems were evaluated. Results: APACHE II on admission had moderate power of discrimination and calibration for mortality and complication prediction in critical care patients. On the other hand, NRS-2002 had insufficient discrimination statistics. Conclusion: APACHE II is superior in outcome prediction compared to NRS-2002 in ICU patient population.
