Variables were selected using LASSO regression. Neonates were categorized into hypothermia and normal temperature groups based on their body temperature during transport, with 6:2:2 ratio for training, test and validation datasets. Six machine learning algorithms—Decision Tree (DT), Random Forest (RF), eXtreme Gradient Boosting (XGBoost), Support Vector Machine (SVM), Artificial Neural Network (ANN), and Naive Bayes (NB)—were used to develop predictive models. The effectiveness was evaluated using area under the ROC curve (AUC), along with F1 score, accuracy, sensitivity, specificity, and Hosmer-Lemeshow calibration tests with Brier scores. The best-performing model was further analyzed for risk factors using SHAP plots.Results: Among the neonates, 5,072 (55.98%) experienced hypothermia during transport. Ten risk factors were identified through univariate analysis and LASSO regression, including gestational age, weight, and immediate postnatal contact. The RF model demonstrated the best overall performance, achieving a training set AUC of 0.994 and an accuracy of 0.957, while the test set AUC and accuracy were 0.962 and 0.889, respectively.Conclusion: Hypothermia incidence during neonatal in-hospital transport is relatively high. The RF-based prediction model demonstrated strong predictive and generalization capabilities, providing actionable guidance for early identification of neonates at risk of hypothermia during transport.Keywords: Neonate, Hypothermia, Intra-hospital Transfer, Predictive Model, Machine Learning |
