Early prediction of incident delirium in traumatic brain injury: a multicenter validated and interpretable machine learning approach
To develop and externally evaluate a machine learning-based predictive model for incident delirium in patients with traumatic brain injury (TBI), highlighting the importance of early prediction in improving patient outcomes.
Key Findings:
Random Forest model achieved an internal AUC of 0.819 and an external AUC of 0.706, indicating strong predictive performance.
Primary predictors included invasive ventilation, Glasgow Coma Scale (GCS), extracranial injury, APSIII, hemoglobin, and mixed intra-/extra-axial injury.
Stratified SHAP analysis highlighted invasive ventilation as the main driver across all strata.
Younger patients and those with extracranial injuries showed robust model generalization, suggesting the model's potential for diverse patient populations.
Interpretation:
The RF model demonstrated acceptable discriminative capacity and clinical utility for early delirium prediction in TBI patients, translating complex predictions into an actionable three-tiered framework for clinical use.
Limitations:
The model's performance may vary in populations with different clinical severity, potentially limiting its generalizability.
External validation was limited to specific databases, which may not represent all TBI patients, raising concerns about broader applicability.
Conclusion:
The RF model serves as a valuable adjunct for guiding early monitoring and neuroprotective strategies in TBI patients at risk of delirium, emphasizing its role in improving patient care.
A nationwide Korean cohort study found modestly higher Parkinson's disease incidence among patients with asthma or allergic rhinitis, with stronger associations observed among patients with greater allergic disease burden.
