Blood Transfusions Are One Of The Most Overused Procedures In Medicine

Blood transfusions have saved countless lives. But blood transfusions can be risky. Emily Anthes writing in Nature gathers the evidence that the procedure is one of the most overused treatments out there, an expensive but potentially dangerous problem.

It’s intuitive to understand why blood transfusions are good. When blood banks that arose out of World War II proved their use, doctors began adopting transfusions widely — without randomised clinical trials to back up many of the practices. “I think we were kind of brainwashed into thinking that blood saves lives, and the more you give the better,” anesthesiologist Steven Frank told Nature.

Lately, doctors have been trying to curb the practice. At Stanford Hospital and Clinics, doctors were prompted to reduce the number of transfusion requests, which ended up cutting costs by by $US1.6 million and reducing length of hospital stays and mortality for patients.

More compelling than the money saved is the the fact that blood transfusions can do serious damage: There is the low, but not zero, risk of receiving infected blood, and then there is the complicated way in which foreign blood interacts with the immune system. Categorising blood into different types (A, B, AB, O and positive/negative) is supposed to prevent harmful immune reactions, but it doesn’t always.
