Routine preoperative ABO\/Rh blood type and antibody screening (T&amp;S) laboratory tests may not be appropriate for all spinal fusion patients. Herein, we constructed a nomogram to assess patient transfusion risk based on various risk factors in patients undergoing spinal fusion surgery, so that preoperative T&amp;S testing can be selectively scheduled in appropriate patients to reduce healthcare and patient costs.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Patients who underwent spinal fusion surgery between 01\/2020 and 03\/2023 were retrospectively examined and classified into the training (n\u2009=\u20093533, 70%) and validation (n\u2009=\u20091515, 30%) datasets. LASSO and multivariable logistic regression were used to analyze risk factors for blood transfusion. Nomogram predictive model was built according to the independent predictors and mode predictive power was validated using consistency index (C\u2010index), Hosmer\u2013Lemeshow (HL) test, calibration curve analysis and area under the curve (AUC) for receiver operating characteristic (ROC) curve. Bootstrap resampling was used for internal validation. Decision curve analysis (DCA) was applied to evaluate the model's performance in the clinic.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Being female, age, BMI, admission route, critical patient, operative time, heart failure, end\u2010stage renal disease or chronic kidney disease (ESRD or CKD), anemia, and coagulation defect were predictors of blood transfusion for spinal fusion. A prediction nomogram was developed according to a multivariate model with good discriminatory power (C\u2010index\u2009=\u20090.887); Bootstrap resampling internal validation C\u2010index was 0.883. Calibration curves showed strong matching between the predicted and actual probabilities of the training and validation sets. HL tests for the training and validation sets had p\u2010values of 0.327 and 0.179, respectively, indicating good calibration. When applied to the training set, the following parameters were found: AUC: 0.895, 95% CI: 0.871\u20130.919, sensitivity 78.2%, specificity 86.7%, positive predictive value 29.4% and negative predictive value 98.2%. If the model were applied in the training set, 2911 T&amp;S tests (82.4%) would be eliminated, equaling a RMB349,320 cost reduction. The AUC in the internal validation was: 0.879, 95% CI: 0.839\u20130.927, sensitivity 75.2%, specificity 88.8%, positive predictive value 34.3%, negative predictive value 97.9%, would eliminate 1276 T&amp;S tests (84.2%), saving RMB 153,120.
