This study utilizes machine learning (ML) to develop a highly sensitive model for timelier identification of at\u2010risk children admitted with acute gastroenteritis (AGE) for better management.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We used seven ML algorithms to build prognostic models for the prediction of mortality using de\u2010identified data collected from children aged &lt;5\u2009years hospitalized with AGE at Siaya County Referral Hospital (SCRH), Kenya, between 2010 through 2020. Potential predictors included demographic, medical history, and clinical examination data collected at admission to hospital. We conducted split\u2010sampling and employed tenfold cross\u2010validation in the model development. We evaluated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and the area under the curve (AUC) for each of the models.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>During the study period, 12\u2009546 children aged &lt;5\u2009years admitted at SCRH were enrolled in the inpatient disease surveillance, of whom 2271 (18.1%) had AGE and 164 (7.2%) subsequently died. The following features were identified as predictors of mortality in decreasing order: AVPU scale, Vesikari score, dehydration, sunken eyes, skin pinch, maximum number of vomits, unconsciousness, wasting, vomiting, pulse, fever, sunken fontanelle, restless, nasal flaring, diarrhea days, stridor, &lt;90% oxygen saturation, chest indrawing, malaria, and stunting. The sensitivity ranged from 46.3%\u201378.0% across models, while the specificity and AUC ranged from 71.7% to 78.7% and 56.5%\u201382.6%, respectively. The random forest model emerged as the champion model achieving 78.0%, 76.6%, 20.6%, 97.8%, and 82.6% for sensitivity, specificity, PPV, NPV, and AUC, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This study demonstrates promising predictive performance of the proposed algorithm for identifying patients at risk of mortality in resource\u2010limited settings.
