HuiyiLi2024 - Prediction of death risk in patients with acute diquat poisoning using Random Forest Model
Ontology highlight
ABSTRACT: The objective of this study was to develop and validate predictive models to assess the risk of death in patients with acute diquat (DQ) poisoning using innovative machine learning techniques. The study analyzed data from 201 consecutive patients admitted for deliberate oral intake of DQ between February 2018 and August 2023 at the First Hospital and Shengjing Hospital of China Medical University. Initial clinical data were collected, and four machine learning methods—logistic regression, random forest, support vector machine (SVM), and gradient boosting—were applied to build the prediction models. The dataset was split into a training set and a test set in an 8:2 ratio. The performance of these models was evaluated in terms of discrimination, calibration, and clinical decision curve analysis (DCA). Additionally, the SHapley Additive ExPlanations (SHAP) interpretation tool was used to provide an intuitive explanation of the risk of death in patients with DQ poisoning by calculating the contribution and impact of each feature on the final prediction. The areas under the receiver operating characteristic curves (AUCs) for the models were 0.91 for logistic regression, 0.98 for random forest, 0.96 for SVM, and 0.94 for gradient boosting. The random forest model demonstrated the best predictive performance with the highest AUC of 0.98, highest F1-score (0.90), highest Matthews correlation coefficient (0.79), highest accuracy (0.90), and the lowest Brier score (0.07). The study concludes that these machine learning models, combined with SHAP, provide reliable and interpretable tools for predicting the death risk in patients with acute DQ poisoning, with the random forest model being identified as the best performing model.
