Transfusion practices vary significantly between hospitals, with preoperative anemia and blood loss predicting red blood cell (RBC) transfusions. Optimizing transfusion strategies is crucial for patient care.

Area of Science:

  • Transfusion Medicine
  • Surgical Outcomes
  • Healthcare Quality Improvement

Background:

  • Benchmarking transfusion activity is essential to identify and reduce inappropriate blood product use.
  • Current transfusion practices require measurement and comparison to optimize strategies.

Purpose of the Study:

  • To measure and compare transfusion practices across public hospitals.
  • To identify predictors of red blood cell (RBC) transfusion.
  • To develop strategies for optimizing transfusion practices.

Main Methods:

  • Prospective observational study in 18 public hospitals (April 2004 - February 2005).
  • Assessed intra- and postoperative blood component transfusion amounts and intercenter variability.
  • Evaluated preoperative anemia, perioperative blood loss, and lowest perioperative hemoglobin (Hb) levels.

Main Results:

  • Large intercenter variability in transfusion rates for total hip replacement (THR), knee replacement (TKR), and coronary artery bypass graft (CABG) surgery.
  • Significant variation in red blood cell (RBC) units transfused and RBC loss between centers.
  • Prevalence of preoperative anemia was 19%, with a three-fold higher incidence in transfused patients.

Conclusions:

  • Significant intercenter variability exists in RBC transfusions and blood loss during standard surgical procedures.
  • Predictors for allogeneic RBC transfusions include preoperative Hb, nadir Hb, and surgical RBC loss.
  • Variability in blood loss remains largely unexplained, necessitating further investigation.
