Insights
A new GASTROVIM score accurately identifies severe acute gastroenteritis (AGE) in children. This validated tool aids in assessing illness severity for better clinical management and outcomes in pediatric patients.
Area of Science:
- Pediatrics
- Infectious Diseases
- Clinical Diagnostics
Background:
- Acute gastroenteritis (AGE) is a common childhood illness.
- Accurate assessment of AGE severity is crucial for appropriate clinical management.
- Existing severity scores may lack optimal diagnostic performance.
Purpose of the Study:
- To develop and validate a novel severity scoring system for acute gastroenteritis in children.
- To enhance the accuracy of clinical severity assessment in pediatric AGE cases.
- To compare the new score's performance against established tools.
Main Methods:
- A predictive score (GASTROVIM) was developed using classification and regression trees.
- Children with AGE were assessed in an emergency department setting.
- Diagnostic performance was compared with the Vesikari score and Clinical Dehydration Scale (CDS).
Main Results:
- The GASTROVIM score identified severe AGE in 129 of 200 children (64.5%).
- GASTROVIM demonstrated high sensitivity (90.0%) and specificity (82.9%) for severe AGE.
- Compared to GASTROVIM, Vesikari score had lower specificity, and CDS had lower sensitivity.
Conclusions:
- The GASTROVIM score shows good diagnostic performance in discriminating severe forms of AGE in children.
- Further external validation in diverse populations is recommended.
- The GASTROVIM score offers a promising tool for pediatric gastroenteritis severity assessment.
Aim:
To develop and internally validate a new severity score to more accurately assess the clinical severity forms of acute gastroenteritis (AGE) in children from birth to age 5 years.
Methods:
We included children consulting for AGE in the emergency department of the University Hospital of Nantes (March 2017-June 2019). We developed and evaluated a new predictive score (GASTROVIM score) using the classification and regression trees. We compared its diagnostic performance with the two existing scores: the Vesikari score and clinical dehydration scale (CDS). A clinical expert a posteriori evaluated children's medical records to determine the severity form of AGE as the gold standard.
Results:
Of the 200 children included, 129 (64.5%) had severe forms of AGE according to the GASTROVIM score (maximal number of liquid stools and vomiting per day, weight loss and CDS), with sensitivity 90.0% (95% CI: 83.5-94.6) and specificity 82.9% (72.0-90.8). The Vesikari score had similar sensitivity (97.3%) but lower specificity (17.0%) and the CDS had lower sensitivity (28.3%) and higher specificity (100%) than the GASTROVIM score.
Conclusion:
The GASTROVIM score could discriminate severe forms of AGE with good diagnostic performance. Nevertheless, external validation in other populations and/or other countries is needed.
