Validation of Paediatric Nutrition Screening Tool (PNST) among Hospitalized Malaysian Children

Background It is recommended to screen hospitalized children to identify those at risk of malnutrition. Constricted schedule in tertiary care settings calls for the needs of a less burdensome yet effective nutrition screening tool. This study aimed to validate the use of Paediatric Nutrition Screening Tool (PNST) among hospitalized children in a Malaysian tertiary hospital. Methods This cross-sectional study recruited children below 18 years old admitting into general paediatric ward in a public hospital. The PNST and Subjective Global Nutritional Assessment (SGNA) were performed on 100 children (64 boys and 36 girls). The objective measurements include anthropometry (z-scores for weight, height and body mass index), dietary history and biochemical markers were measured. These were used to classify malnutrition as per Academy of Nutrition and Dietetics/American Society of Parental and Enteral Nutrition (AND/ASPEN) Consensus Statement for identification of paediatric malnutrition and WHO growth standards for children. Cohen’s kappa was computed to report the level of agreement. Results The PNST identified 57% of hospitalized children as being at risk of malnutrition. In this study, there was a stronger agreement between PNST with AND/ASPEN malnutrition classification (k = 0.602) as when PNST was compared with WHO (k = 0.225) and SGNA (k = 0.431). The PNST shows higher specificity (85.29%) and sensitivity (78.79%) when compared with AND/ASPEN than with WHO malnutrition criteria (55.81% specificity and 66.67% sensitivity). Conclusion This study showed the usefulness of routine use of PNST for screening the malnutrition risk of hospitalized children in Malaysian tertiary hospital settings.
