Three main reasons:

I – Blood is an exhaustible resource and is in short supply worldwide. Most national and international blood banks are with its scarce stocks below of what would be the ideal.

According to a study conducted in 2007, the demand for blood in Brazil grows at a rate of 1% per year, while donations grow 0.5% to 0.7% per year, indicating that in the near future, we will have to get along with the possibility of not having blood available for all medical procedures. Fewer transfusions mean savings for blood banks.

II – Blood transfusion increases hospital costs as it increases patient’s length of stay in the hospital, especially higher ICU (Intensive Care Unit) length of stay. The longer the patient stay in hospital higher will be the hospital costs. Fewer transfusions mean lower hospital costs.

III – Treatment using transfusion of allogeneic blood (someone else’s blood) may result in myocardial infarction, cardiac arrhythmia, renal failure, stroke, multiple organ failure, and transmission of up to 68 (sixty eight) infectious agents (bacteria, viruses, protozoa, worms). The main side effect that the latest researches have shown is the higher risk of death after a blood transfusion. It has found further that this risk of patient death increases proportionally with the number of transfused units, that is, the more is someone else’s blood that the patient receives, the higher is the risk of dying.

Fewer transfusions mean less complications, less death, more life
