    A multimodal machine learning framework was developed to predict in-hospital type 2 respiratory failure (T2RF) during acute exacerbations of COPD.

  • 2

    The study utilized a development cohort of 6,954 AECOPD patients and an external validation cohort of 1,252 patients from multiple hospitals.

  • 3

    XGBoost achieved an AUROC of 0.699 in the external validation set, indicating its effectiveness in predicting T2RF.

  • 4

    Key predictors identified included lymphocyte count, eosinophil count, COPD duration, age, hypertension, and sex.

  • 5

    A logistic nomogram was created, achieving an external AUROC of 0.666, providing a practical tool for clinicians.
