Abstract
Preoperative autologous blood donation is used by only a small percentage of surgery patients for whom crossmatched blood is ordered. To document the reasons the patients failed to donate, the medical records of surgical patients at three university and three community hospitals were studied. All procedures for which crossmatched blood was ordered, but for which autologous blood was not available, were included (n = 8121). Probable reasons for nondonation were found in 72 percent of university hospital patients and 65 percent of community hospital patients (n = 6064 and n = 2057, respectively). The most frequent reasons for nondonation among university hospital patients were emergency surgery (27%) and age < 12 years (17%), and those among community hospital patients were emergency surgery (42%) and American Society of Anesthesiologists physical status ≥to 4 (20%). Surprisingly, anemia (hemoglobin < 11 g/dL [< 110 g/L]) as the only limitation to donation was rarely found: this was the sole reason in only 3.3 percent of university hospital and 4.5 percent of community hospital patients. Overall, of 8121 patients who failed to donate autologous blood, 5731 (71%) had legitimate medical reasons. The remaining 2390 (29%) had no identifiable reason for nondonation, and recruitment efforts should be focused on them and their surgeons.
