Despite having possibly the silliest acronym in the history of medicine (in Dr. Chaffin's opinion!), TACO is a very serious disease. It is responsible for the second-most number of deaths from transfusion every year in the United States (and is #1 in the United Kingdom). TACO is not something to mess around with, but far too many clinicians and blood bankers fail to give it the respect it deserves. Dr. Garrett Booth joins Dr. Chaffin in an energetic and fast-moving discussion of the "ins and outs" of TACO.
