Other

This is an observational study aimed at developing and validating a predictive model for perioperative blood transfusion. The study utilizes retrospective clinical data from surgical patients to identify key risk factors associated with transfusion requirements. No experimental intervention will be applied to participants, as the study solely focuses on data analysis and model development.

Primary outcomes

  1. Intraoperative transfusion

    Time frame: From surgical incision to the end of surgery

    The primary outcome measure is the occurrence of intraoperative blood transfusion. This includes any administration of red blood cells, plasma, or platelets during the surgical procedure. The study aims to predict transfusion requirements based on preoperative clinical factors.
