Construction and validation of a machine learning-based prediction model for venous thromboembolism in lung transplant recipients supported by ECMO
To investigate risk factors for venous thromboembolism (VTE) in lung transplant recipients receiving ECMO and to develop a machine learning-driven VTE risk prediction model.
Key Findings:
The Random Forest model had the best performance with an AUC of 0.895.
Accuracy was 89.7%, sensitivity 89.7%, specificity 89.5%, PPV 94.6%, and NPV 81.0%.
Calibration curve showed strong agreement between predicted probabilities and observed outcomes.
The F1 score was also calculated to assess model performance.
Interpretation:
The ML-derived VTE risk prediction model demonstrated strong predictive ability and clinical utility.
Limitations:
The study was conducted at a single center, which may limit generalizability to other settings.
The retrospective nature may introduce bias, affecting the reliability of the findings.
Conclusion:
The machine learning model provides a validated tool for predicting VTE risk in lung transplant patients on ECMO.
