| No intervention (observational study) | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Intraoperative transfusion | 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. | From surgical incision to the end of surgery |

This study includes adult patients (≥18 years old) who underwent major abdominal surgery at a tertiary medical center. The study population consists of patients with available preoperative clinical and laboratory data, allowing for the development of a predictive model for intraoperative blood transfusion. Patients with known hematologic disorders, coagulopathy, or prior transfusion before surgery are excluded to minimize confounding factors.
