Lucky Number 7

In Day 20 of #CritBits I explore why we use a hemoglobin level of 7 as the transfusion threshold for hemodynamically stable patients. This number has been scrutinized across various patient populations, including those in critical care, trauma, and with GI bleeds, due to risks associated with transfusions, such as reactions, infections, and transfusion-associated circulatory overload (TACO). In the 90s, the TRICC investigators compared outcomes between patients with hemoglobin levels of 10 and 7, finding no differences in morbidity and mortality, with the 7 group actually doing better. Interestingly, during my fellowship, one of the TRICC investigators revealed that they chose 7 simply because it's a lucky number, highlighting that not everything in medicine is as evidence-based as we might think.
