Seven different scoring systems used for prediction of perioperative bleeding were compared regarding patients operated for elective open cardiac surgery in the investigator's study.
Collected data of 500 consecutive patients, operated for elective open cardiac surgery were analyzed retrospectively. Seven different scoring systems were used to predict the probability of bleeding, including TRACK, PAPWORTH, WILL-BLEED, CRUSADE, ACTION, TRUST and ACTA-PORT. The scores are calculated for each of these systems by using their own parameters, and classified into four risk groups as very low, low, moderate and high. Then, these risk groups were compared with patients identified in two groups regarding the use of perioeprative erythrocyte suspension (ES) transfusions or not, as ES positive and ES negative.

Bleeding scores
Bleeding scores were calculated in points ranging from 0 to 4.(0 the lowest and 4 the highest risk score for bleeding)
Time frame: Bleeding risk scores were calculated through study completion, an average of 2 years.
The amount of blood transfusions
The amount of blood transfusions were recorded in units.
Time frame: The amount of blood transfusions were recorded through study completion, an average of 2 years.
