Last October, physicians led by Drs. James Baker, Katerina Pavenski and Gregory Hare started giving the drug TXA, or tranexamic acid, a drug used to prevent excessive blood loss during surgery, to all patients undergoing hip or knee replacements.
Within three months the transfusion rate for patients undergoing hip replacements dropped from 13.7 per cent to 6.6 per cent. The transfusion rate for knee replacements fell from 7.9 per cent to 5.2 per cent. That rate was already low because of the hospital’s commitment to blood management and the Ontario Transfusion Coordinators (ONTraC) program, which is administered by St. Michael’s.
The drug costs $15 per patient, while the average cost of transfusing one unit of blood is $1,200.
In the past, the drug was given only to patients at high risk of requiring a blood tranfusion, in part because of a province-wide shortage of the drug.
“We did more than 650 hip replacements last year so that’s 45 or so transfusions saved,” said Dr. Hare, an anesthesiologist and one of the founders of the hospital’s Centre of Excellence for Patient Blood Management. “Patients go home with higher hemoglobin levels, less anemia and fewer transfusions for just $15.”
