BACKGROUND: . Early prediction of whether the disease will progress to a severe state is crucial for clinicians to provide targeted medical care in advance. METHODS: This study retrospectively collected severe and mild ST cases in two hospitals in Fujian Province, China from 2011 to 2022. Eighteen objective clinical and laboratory features collected at admission were screened using various feature selection algorithms, and used to construct models based on six machine learning algorithms. RESULTS: The model based on Gradient Boosting Decision Tree using 14 features screened by Recursive Feature Elimination was evaluated as the optimal one. The model showed high accuracy, precision, sensitivity, specificity, F-1 score, and area under receiver operating characteristics curve of 0.975, 0.967, 0.983, 0.966, 0.975, and 0.981, respectively, indicating its possible clinical application. Additionally, a simplified model based on Support Vector Machine was constructed and evaluated as an alternative optimal model. CONCLUSIONS: This study is the first to use machine learning algorithms to accurately predict the developments of ST patients upon admission to hospitals. The models can help clinicians assess the potential risks of their patients early on, thereby improving patient outcomes.

May aid early risk stratification in scrub typhus; hypothesis-generating and requires prospective validation before clinical use.

Lu et al. (2025) conducted an observational in Scrub typhus (n=226). Gradient Boosting Decision Tree (GBDT) machine learning model using Recursive Feature Elimination (RFE) was evaluated on Prediction of scrub typhus progression to a severe state (Area Under the Curve). The Gradient Boosting Decision Tree model using 14 features accurately predicted the progression of scrub typhus to a severe state at hospital admission with an AUC of 0.981, sensitivity of 0.983, and specificity of 0.966.
