Area of Science:

  • Neurosurgery
  • Medical Informatics
  • Data Science

Background:

  • Delirium is a common complication following microvascular decompression (MVD).
  • Predicting and preventing postoperative delirium is crucial for patient recovery.
  • Machine learning offers potential for developing predictive models in clinical settings.

Purpose of the Study:

  • To develop and validate machine learning models for predicting early delirium after MVD.
  • To identify key preoperative and intraoperative factors associated with postoperative delirium.

Main Methods:

  • A retrospective cohort study of 912 patients undergoing MVD.
  • Data collected included preoperative, intraoperative, and postoperative variables.
  • Machine learning models (logistic regression, random forest, gradient boosting, decision tree, GBDT) were trained and tested.

Main Results:

  • Postoperative delirium occurred in 24.2% of patients.
  • The GradientBoosting algorithm achieved the highest accuracy (97.0% in training, 92.3% in testing).
  • Significant predictors included carbamazepine (CBZ) use duration, hemoglobin (hgb), serum CBZ level, preoperative CBZ dose, and blood urea nitrogen (BUN).

Conclusions:

  • Machine learning models can effectively predict delirium after MVD with high accuracy.
  • Carbamazepine, hgb, and BUN are major risk factors for developing postoperative delirium.
  • These findings can inform clinical practice for delirium prevention strategies.
