Our facility received a pitch for this testing also. After a thorough evaluation of current blood usage, costs associated with the TEG system, etc., the physician-based team recognized that our Cardiac department wasn't really overusing blood. Our pathologists reviewed indications/usage and didn't really see where there was much room for improvement. That being said, the real interest in TEG came from our Trauma surgeons. However, they were drawn in by the earliest reading time quoted from the test system and said if they had to wait until the run was complete for the most accurate result, it may not help them either. Lab was insistent the instrument not be based in the OR/ER because of the potential for basing transfusion decisions before the test had completed its entire cycle. I do not have access to the complete detail on this study, so I hope this short synopsis helps.
