A Novel Scoring System Predicting Red Blood Cell Transfusion Requirements in Patients Undergoing Invasive Spine...

Area of Science:

• Anesthesiology and Perioperative Medicine
• Hematology
• Neurosurgery

Background:

• Blood product availability is critical for patient safety during surgery.
• Blood shortages and German regulations on red blood cell (RBC) allocation challenge surgical scheduling.
• Predictive models are needed to optimize RBC use in spine surgery.

Purpose of the Study:

• Develop a predictive scoring system for perioperative RBC transfusion in spine surgery.
• Improve the availability of blood products by reducing unnecessary RBC assignments.
• Enhance patient safety and surgical scheduling efficiency.

Main Methods:

• Retrospective analysis of 252 spine surgery patients' medical records.
• Evaluation of 18 potential predictors for RBC transfusion.
• Construction of a logistic-regression-based predictive scoring system.

Main Results:

• Key predictors identified: surgery type, vertebral body replacement, number of stages, and pre-operative hemoglobin.
• Surgical factors and procedure extent were more influential than patient condition or medication.
• The developed scoring system demonstrated good predictive ability (AUC 0.87).

Conclusions:

• A validated scoring system can forecast perioperative transfusion needs in spine surgery.
• Pre-operative prediction of RBC requirements can optimize blood product allocation.
• This approach may mitigate blood shortages and improve resource availability.
