Subjective global nutritional assessment in critically ill children

Area of Science:

• Pediatric Intensive Care
• Clinical Nutrition
• Medical Assessment

Background:

• Underweight children in the PICU face increased mortality risks.
• Malnutrition identification is crucial for improving outcomes in critically ill children.
• Existing assessment methods may not fully capture nutritional status in the PICU.

Purpose of the Study:

• To evaluate the utility of Subjective Global Nutrition Assessment (SGNA) in identifying malnutrition in pediatric intensive care unit (PICU) patients.
• To determine if SGNA can predict nutrition-associated morbidities in this population.
• To assess the correlation between SGNA and objective anthropometric and laboratory measurements.

Main Methods:

• A prospective study involving 150 children (31 days to 5 years) admitted to the PICU.
• Nutrition status assessed using SGNA by a dietitian and objective measurements by an independent assessor.
• Interrater reliability of SGNA tested on 76 children; nutrition-associated complications documented for 30 days.

Main Results:

• SGNA ratings correlated moderately to strongly with standard anthropometric measurements (P < .05).
• Laboratory markers showed no significant correlation with SGNA findings.
• Interrater agreement for SGNA demonstrated moderate reliability (κ = 0.671).

Conclusions:

• SGNA is a reliable tool for assessing malnutrition in PICU patients, correlating well with anthropometric data.
• While SGNA shows promise, it did not significantly correlate with length of stay or mortality scores (PoliD, PIM III).
• Further research may explore SGNA's predictive value for specific nutrition-associated morbidities in critically ill children.
