Insights
A new Pediatric Nutrition Screening Tool (PNST) offers a simple and accurate method for identifying malnutrition risk in hospitalized children. This validated tool improves upon existing methods for early detection and intervention.
Area of Science:
- Pediatric Nutrition
- Clinical Assessment
- Healthcare Quality Improvement
Background:
- Malnutrition is prevalent in hospitalized children, yet routine screening tools are not widely implemented.
- Existing pediatric nutrition risk tools lack the simplicity of adult screening methods.
- This study introduces a novel, quick, and simple Pediatric Nutrition Screening Tool (PNST) for inpatient use.
Purpose of the Study:
- To develop and validate a simple Pediatric Nutrition Screening Tool (PNST) for hospitalized children.
- To assess the accuracy of the PNST against established pediatric nutrition assessment methods.
- To provide a more accessible screening tool for early malnutrition detection in pediatric inpatients.
Main Methods:
- The PNST was developed using 4 simple nutrition screening questions, validated against the pediatric Subjective Global Nutrition Assessment (SGNA) and anthropometric measures.
- Data were collected from 295 pediatric inpatients across 3 tertiary and regional hospitals.
- The accuracy of the PNST was evaluated using sensitivity and specificity analyses.
Main Results:
- The PNST, with two affirmative answers, demonstrated optimal sensitivity (77.8%) and specificity (82.1%) compared to the pediatric SGNA.
- It identified 37.6% of patients at nutrition risk, slightly higher than the pediatric SGNA (34.2%).
- The PNST showed high sensitivity (89.3%) for detecting low BMI z-scores but moderate specificity (66.2%); both tools were less effective for stunting or overweight detection.
Conclusions:
- The PNST is a sensitive, valid, and simpler alternative to existing pediatric nutrition screening tools like STAMP, STRONGkids, and PYMS.
- It facilitates the early detection of nutrition risk in hospitalized children.
- Implementation of the PNST can improve nutritional care for pediatric inpatients.
Background:
Pediatric nutrition risk screening tools are not routinely implemented throughout many hospitals, despite prevalence studies demonstrating malnutrition is common in hospitalized children. Existing tools lack the simplicity of those used to assess nutrition risk in the adult population. This study reports the accuracy of a new, quick, and simple pediatric nutrition screening tool (PNST) designed to be used for pediatric inpatients.
Materials And Methods:
The pediatric Subjective Global Nutrition Assessment (SGNA) and anthropometric measures were used to develop and assess the validity of 4 simple nutrition screening questions comprising the PNST. Participants were pediatric inpatients in 2 tertiary pediatric hospitals and 1 regional hospital.
Results:
Two affirmative answers to the PNST questions were found to maximize the specificity and sensitivity to the pediatric SGNA and body mass index (BMI) z scores for malnutrition in 295 patients. The PNST identified 37.6% of patients as being at nutrition risk, whereas the pediatric SGNA identified 34.2%. The sensitivity and specificity of the PNST compared with the pediatric SGNA were 77.8% and 82.1%, respectively. The sensitivity of the PNST at detecting patients with a BMI z score of less than -2 was 89.3%, and the specificity was 66.2%. Both the PNST and pediatric SGNA were relatively poor at detecting patients who were stunted or overweight, with the sensitivity and specificity being less than 69%.
Conclusion:
The PNST provides a sensitive, valid, and simpler alternative to existing pediatric nutrition screening tools such as Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP), Screening Tool Risk on Nutritional status and Growth (STRONGkids), and Paediatric Yorkhill Malnutrition Score (PYMS) to ensure the early detection of hospitalized children at nutrition risk.
