Platelet transfusion decisions are too important to be made by looking at just one number. Joe Sweeney wants to show you a better way!

Better Information Means Better Decisions
Platelet transfusion decisions can be complex, and there is wide practice variability both within institutions and among different subspecialty services. In this wide-ranging, very practical interview, Dr. Sweeney describes current platelet transfusion guidelines and a more thorough approach to caring for thrombocytopenic patients. More importantly, he helps us understand the questions we should be asking, whether we are in charge of transfusing a patient or reviewing someone else’s transfusion decisions.

I think it’s really important as we try to manage all blood components to shift transfusion culture, and part of that is talking to our colleagues, not the morning of the procedure when it becomes a bit of an emergency, but actually long in advance of that, you know, weeks or months in advance to go to their meetings and to talk to them about these issues and that helps a lot. It may not solve every problem, but it helps in many, many situations.

Great discussion! I found the discussion regarding the risk of liver biopsy being greater when done for masses rather than to diagnosis hepatitis or cirrhosis fascinating. Do we think that elevated levels of vWF and/or reduced levels of ADAMTS13 seen in cirrhosis have anything to do with this dichotomy? Or is there some other theory for why these two groups behave differently?
In the NEJM study by Afdhal et al, they found that use of the TPO mimetic eltrombopag was associated with increased risk of portal vein thrombosis when given to cirrhotics with thrombocytopenia prior to invasive procedures. Is there any literature that would shed light on whether increasing platelet counts through transfusion may lead to a similar increased risk of thrombotic events?
Thanks again for a great discussion!
Jeannie Callum addressed some of these questions in her excellent interview, Transfusion in Liver Disease (episode 056). Check that out for some of the answers to the questions you’ve asked.
