Clinical Scorecard: Evaluating Manual and Automated Approaches in Machine Learning and Deep Learning for Forecasting One-Year Mortality in Older Adults with Hip Fractures

At a Glance

Key Highlights

• Study included 2,604 elderly patients undergoing urgent hip fracture surgery.
• Manually optimised Extreme Gradient Boosting (XGB) algorithm showed superior predictive performance (AUC = 0.846).
• Automated ML model using LLM and TPOT demonstrated comparable performance (AUC = 0.844).
• Key predictors included serum albumin, urea levels, patient age, intraoperative hypothermia, and number of chronic diseases.
• ML models enhance predictive accuracy for one-year mortality in elderly hip fracture patients.

Guideline-Based Recommendations

Diagnosis

• Utilize comprehensive clinical, demographic, perioperative, and laboratory variables for risk assessment.

Management

• Implement ML-based models to guide perioperative care and resource allocation.

Monitoring & Follow-up

• Regularly assess model performance using metrics such as AUC, accuracy, and F1-score.

Risks

• Consider high postoperative mortality rates, which can reach up to 36% within the first year.

Patient & Prescribing Data

Elderly patients aged 65 years and older with hip fractures.

Focus on identifying high-risk patients for targeted perioperative management.

Clinical Best Practices

• Employ ML algorithms to manage complex, nonlinear predictor interactions.
• Utilize automated ML platforms to democratize access to predictive analytics in clinical settings.
• Ensure rigorous model validation through stratified cross-validation and addressing class imbalance.
