Insights
Diagnosing appendicitis in children is challenging. An AI model, AiPAD, accurately identifies appendicitis using clinical data alone, avoiding imaging and improving patient outcomes.
Area of Science:
- Pediatric Medicine
- Artificial Intelligence in Healthcare
- Diagnostic Accuracy
Background:
- Diagnosing appendicitis in young children (0-12 years) presents significant challenges, even with advanced imaging techniques.
- Existing diagnostic scoring models show variable accuracy upon validation in pediatric populations.
Purpose of the Study:
- To develop and validate an artificial intelligence (AI) diagnostic model for appendicitis in children using only clinical and laboratory parameters.
- To prospectively validate the AI model's diagnostic performance without relying on imaging data.
Main Methods:
- Stage I involved developing the AI Pediatric Appendicitis Decision-tree (AiPAD) model using observational data from 166 children (0-12 years) with acute appendicitis.
- 10-fold cross-validation (XV) was employed for initial model evaluation, simulating prospective validation.
- Stage II involved prospective validation of the AiPAD model on 139 children, comparing results with XV estimates.
Main Results:
- The developed AiPAD model demonstrated high accuracy with XV estimation: 93.5% ± 5.8% (91.4% PPV, 94.8% NPV).
- Prospective validation confirmed the model's accuracy, achieving 97.1% overall accuracy (96.7% PPV, 97.4% NPV).
- The AI model is both accurate and explainable, providing reliable diagnostic predictions.
Conclusions:
- The validated AiPAD model offers a highly accurate, easy-to-understand tool for diagnosing pediatric appendicitis without imaging.
- This AI-driven approach can lead to significant practical benefits, including improved patient outcomes and reduced healthcare costs.
- AiPAD provides an invaluable non-imaging tool for pediatric appendicitis diagnosis.
Introduction:
Diagnosing appendicitis in young children (0-12 years) still poses a special difficulty despite the advent of radiological investigations. Few scoring models have evolved and been applied worldwide, but with significant fluctuations in accuracy upon validation.
Aim:
To utilize artificial intelligence (AI) techniques to develop and validate a diagnostic model based on clinical and laboratory parameters only (without imaging), in addition to prospective validation to confirm the findings.
Methods:
In Stage-I, observational data of children (0-12 years), referred for acute appendicitis (March 1, 2016-February 28, 2019, n = 166), was used for model development and evaluation using 10-fold cross-validation (XV) technique to simulate a prospective validation. In Stage-II, prospective validation of the model and the XV estimates were performed (March 1, 2019-November 30, 2021, n = 139).
Results:
The developed model, AI Pediatric Appendicitis Decision-tree (AiPAD), is both accurate and explainable, with an XV estimation of average accuracy to be 93.5% ± 5.8 (91.4% positive predictive value [PPV] and 94.8% negative predictive value [NPV]). Prospective validation revealed that the model was indeed accurate and close to the XV evaluations, with an overall accuracy of 97.1% (96.7% PPV and 97.4% NPV).
Conclusion:
The AiPAD is validated, highly accurate, easy to comprehend, and offers an invaluable tool to use in diagnosing appendicitis in children without the need for imaging. Ultimately, this would lead to significant practical benefits, improved outcomes, and reduced costs.
