A machine learning model predicts acute pulmonary embolism risk in suspected patients to reduce unnecessary CTPA overuse and radiation exposure and provides interpretable explanations for individual risk predictions.
Abstract
Highlights • A machine learning model predicts acute pulmonary embolism risk in suspected patients.• LASSO and logistic regression identified key clinical predictors from 77 variables.• Eight ML algorithms were compared to select the optimal predictive model.• SHAP framework provides interpretable explanations for individual risk predictions.• The model aims to reduce unnecessary CTPA overuse and radiation exposure.
Pulmonary metastasis in high‐grade conventional osteosarcoma remains a leading cause of treatment failure and mortality. Traditional monitoring methods are insufficient for early detection. This study aims to develop and validate an interpretable machine learning (ML) model using multi‐dimensional data from electronic...

ICU‐acquired weakness (ICU‐AW) is a common and debilitating complication among critically ill patients, particularly those undergoing major surgery. Early identification of patients at high risk of ICU‐AW may facilitate timely preventive strategies and targeted rehabilitation interventions.
An interpretable XGBoost model that accurately predicts pneumonia risk in AL patients based on routine admission data is developed and validated and provides actionable risk stratification to inform preemptive diagnostic and therapeutic strategies.

Patients with dementia have high rehospitalization rates, creating substantial clinical and economic burden. Machine learning (ML) may help predict readmission risk, but its use for clinically relevant outcomes such as rehospitalization in dementia remains limited. This study evaluated the performance of several ML alg...
