Aim: Red blood cell transfusion may be inevitable in cardiac surgery due to both blood loss and hemodilution secondary to cardiopulmonary bypass. Transfusion strategies may change over time owing to technological advances. The aim of this study was to evaluate the effect of the patient blood management education applied to healthcare staff on the number of red blood cell transfusions and clinical outcomes of the patients undergoing cardiac surgery. Material and Methods: Patients were included to the study if they had undergone coronary artery bypass grafting and/or heart valve surgery at the cardiovascular surgery clinic of tertiary training and research hospital during the five-year period between January 1, 2013 and December 31, 2017. Age, sex, number of RBC transfusions, Euroscore II, type of surgery, duration of mechanical ventilation, length of intensive care unit (ICU) stay, length of hospital stay, and in-hospital mortality of the patients were recorded. As the intervention, a patient blood management course was held for anesthesia and intensive care unit staff the department of cardiovascular surgery in December 2015. Patient blood management program was started as of 1st January of 2016 during perioperative period in cardiac surgery patients. Patients were divided into two groups as those undergoing cardiac surgery before January 2016 (Group I, the control group) and those having the surgery after January 2016 (Group II, the intervention group). The groups were compared in terms of sex, age, Euroscore II, duration of mechanical ventilation at intensive care unit, length of stay at intensive care unit and hospital, and in-hospital mortality. Results: A total of 691 patients were found to meet inclusion criteria. The patients in Group I and Group II were statistically similar in age, sex, and Euroscore II. Mean number of RBC transfusions were 3.55 ± 1.49 in Group I and 2.77 ± 1.64 in Group II (p<0.001). The duration of mechanical ventilation in Group I (6.56 ± 1.18 days) was significantly longer than that in Group II (5.93 ± 14.1 days), (p<0.001). There was no statistically significant difference between the groups in terms of length at ICU and hospital (p=0.255 and p=0.823, respectively). The mortality rate was 3.0% in Group I and 3.5% in Group II, where the difference was not statistically significant (p=0.736). Conclusion: The training of healthcare personnel about current “patient blood management” protocols was associated with reduced number of perioperative RBC transfusions and partially improved clinical outcomes in patients undergoing cardiac surgery.
