Core Tip
Core Tip: Traditional models have been built to identify risk factors for extended length of stay (eLOS), offering new insights for optimizing treatment for hip fracture patients under the enhanced recovery after surgery concept. However, these traditional statistical methods suffer from poor performance and lack of features. Machine learning (ML) is a scientific discipline focused on teaching computers to learn from data, showing superior predictive performance compared to traditional methods. This study aims to develop ML models for predicting eLOS among geriatric patients with hip fractures, identify associated risk factors, and compare the performance of each model.
