Title: Modeling Predictors for Blood Transfusion in Patients with Small and Large Bowel Procedures

Abstract:

Blood transfusion during surgery is critical. Identifying the predictors would make the preparation for surgery easier for physicians and safer for the patients. This study was conducted to evaluate the predictors of transfusion before the implementation of a blood conservation program. Patients who had the small and large bowel procedures at Jersey Shore University Medical Center in 1999--2000 were included. Multiple logistic regression models were utilized. A total of 263 adult patients (mean [SD] age: 64 [17] years; 51% female) were in this study. Ninety-four patients (35%) had a blood transfusion. Forty-five percent were given blood before surgery. The significant predictors for any blood transfusion are age, admission hemoglobin value (HGB), pulse, and DBP. However, only age and HGB are significant predictors of the preoperative blood transfusion. This is the first study to document the predictors for blood transfusion in this patient population. A high percentage of transfusion was provided before the surgery. For hospital administration, more information on the outcome will impact the predictor, which is critical for decisionmaking in a blood conservation program.
