Deep learning models, including CNN-ViT, show promise for early sepsis prediction using electronic health records. Combining local feature extraction with temporal and attention modeling improves early sepsis detection in intensive care units.

Area of Science:

  • Critical Care Medicine
  • Biomedical Informatics
  • Artificial Intelligence in Healthcare

Background:

  • Sepsis is a life-threatening condition requiring early detection in intensive care units (ICUs) for improved patient outcomes.
  • Electronic health records (EHRs) contain valuable data for developing predictive models.
  • Deep learning offers potential for analyzing complex EHR data for sepsis prediction.

Purpose of the Study:

  • To retrospectively evaluate various deep learning architectures for early sepsis prediction.
  • To predict sepsis onset up to 6 hours before clinical recognition using structured EHR data.
  • To compare the performance of different deep learning models in identifying sepsis.

Main Methods:

  • Utilized hourly structured EHR variables (vitals, labs, demographics) for model training.

A Data-Driven Approach to Quantifying Immune States in Sepsis

Published on: February 7, 2025

  • Evaluated architectures: CNN, LSTM, GRU, Bi-LSTM, TCN, Transformer, and CNN-ViT.
  • Applied median imputation for missing values and class-weighted loss for imbalance; used SHAP and attention for interpretability.

    • Main Results:

    • The hybrid Convolutional Neural Network-Vision Transformer (CNN-ViT) model demonstrated the strongest performance for the minority class.
    • CNN-ViT achieved 88.25% accuracy, 0.7480 recall, 0.454 F1-score, and 0.48 AUPRC.
    • Performance remained relatively stable under internal distribution shifts, indicating robustness.

    Conclusions:

    • Combining local feature extraction with temporal and attention-based modeling enhances early sepsis prediction from structured ICU data.
    • The CNN-ViT architecture shows significant potential for improving early sepsis detection.
    • Further prospective clinical validation is needed to assess real-world deployment effectiveness.
