Using machine learning for early prediction of in-hospital mortality during ICU admission in liver cancer patients
This study developed and validated machine learning models for early prediction of in-hospital mortality in critically ill liver cancer patients admitted to the ICU. Utilizing data from MIMIC-III (training) and MIMIC-IV (validation) databases, four ML algorithms (logistic regression, random forest, XGBoost, LightGBM) were evaluated. The random forest model demonstrated superior performance (AUROC 0.911 internal, 0.857 external). Key predictive features included severity scores (APSIII, SAPSII, LODS, OASIS) and vital signs. This research highlights the significant potential of ML in clinical risk assessment for liver cancer patients in ICU, facilitating timely interventions.

Critical Predictive Features Identified
APSIII, SAPSII, LODS, OASISSeverity Scores
These clinical severity scores were consistently identified as the most important factors influencing in-hospital mortality prediction across all datasets. They encapsulate the patient's physiological status and organ dysfunction, providing strong predictive power.
Clinical Utility and Intervention
Early Risk Stratification in ICU
Scenario: A 68-year-old liver cancer patient is admitted to the ICU with acute liver failure. The Random Forest ML model, fed with initial vital signs and severity scores (APSIII, SAPSII), predicts a 'high-risk' mortality probability of 78%.
Impact: Based on this early prediction, the clinical team can prioritize aggressive interventions, including closer monitoring, immediate adjustment of treatment protocols, and early consultation for specialized care. This proactive approach significantly increases the chances of survival compared to standard protocols.
Value Proposition: Implementing such a model allows for early identification of high-risk patients, enabling targeted resource allocation and potentially reducing in-hospital mortality rates by facilitating timely and aggressive treatment strategies. This translates into improved patient outcomes and more efficient ICU management.
