Establishment of a predictive model for blood transfusion after femoral head replacement in elderly patients

A nomogram prediction model that effectively assesses the risk of blood transfusion in elderly patients undergoing femoral head replacement for intertrochanteric femoral fractures was established in this study. This model demonstrated high predictive accuracy and consistency, providing a valuable tool for clinicians to identify high-risk patients and implement early interventions to reduce the need for postoperative blood transfusions.
