Summary
Postoperative anemia after hip fracture significantly impacts patient outcomes. This study developed an online tool using machine learning to predict anemia risk, aiding early prevention strategies.
Area of Science:
- Orthopedic Surgery
- Geriatric Medicine
- Computational Biology
Background:
- Postoperative anemia is a significant complication following intertrochanteric hip fracture surgery.
- This complication negatively affects patient outcomes and recovery.
- Developing predictive tools is crucial for proactive management and prevention.
Purpose of the Study:
- To develop an online predictive tool for postoperative anemia in intertrochanteric hip fracture patients.
- To assist clinicians in creating targeted surgical blood preparation strategies.
- To mitigate the occurrence and impact of postoperative anemia.
Main Methods:
- Utilized data from 815 intertrochanteric hip fracture patients (June 2017-June 2025).
- Employed LASSO regression for variable selection and compared seven machine learning models (SVM, Logistic Regression, Decision Tree, LightGBM, XGBoost, Neural Networks, Random Forest).
- Developed a patient-specific risk prediction tool with SHAP interpretability.
Main Results:
- 25.5% of patients developed postoperative anemia.
- The Support Vector Machine (SVM) model demonstrated superior predictive performance (AUC 0.827-0.831).
- SVM achieved high sensitivity (72.73%), accuracy (77.78%), and F1 score (57.14%) in diverse test sets.
Conclusions:
- An effective online prediction platform for postoperative anemia risk in hip fracture patients was established.
- The tool supports clinical decision-making for early anemia prevention.
- Facilitates improved patient outcomes by enabling proactive management strategies.
