    The study identified independent predictors of in-hospital cardiac arrest (IHCA) including atrial fibrillation, heart failure, and end-stage renal disease.

  • 2

    Modified Early Warning Score (MEWS) was associated with IHCA risk up to 16 hours prior, with lower SpO₂ being significant in the final 8 hours.

  • 3

    A calibrated XGBoost model achieved an Area Under the Receiver Operating Characteristic curve of 0.89 and average precision of 0.88 in predicting IHCA.

  • 4

    The study emphasizes the importance of integrating comorbidity burden and laboratory indices into early warning systems for IHCA.

  • 5

    Prospective multicenter validation is necessary to recalibrate the model's predictive performance to real-world prevalence before clinical deployment.
