Objective:

To develop a machine learning-based clinical decision-support tool for predicting specific postoperative complications, such as infection and hematoma, following cranioplasty.

Key Findings:
  • Random forest model demonstrated the best performance with AUROC = 0.949.
  • High discriminative performance maintained across subgroups, with the lowest AUROC being 0.927.
  • Subcutaneous negative-pressure drainage and titanium mesh showed protective effects against complications.
Interpretation:

The findings provide a practical framework for risk stratification and optimization of intraoperative decision-making in cranioplasty, potentially improving patient outcomes.

Limitations:
  • The study may have limitations related to the generalizability of the findings across different populations, particularly in diverse clinical settings.
  • Potential biases in data collection and feature selection, such as selection bias or measurement error, could affect model performance.
Conclusion:

The developed machine learning tool offers a significant advancement in predicting postoperative risks in cranioplasty, enhancing clinical decision-making.
