Transfusion

Patients with severe thrombocytopenia are at risk for bleeding during insertion of central venous catheters (CVCs). Although most guidelines recommend preprocedural platelet (PLT) transfusions at a threshold of less than 50 × 10(9) /L, there is only weak evidence supporting such recommendations. ⋯ CVC placements can safely be performed in patients with PLT counts of 20 × 10(9) /L or more without preprocedural PLT transfusions.

Blood transfusion is the most common procedure performed in American hospitals, and transfusions are commonly ordered by physicians without formal training in transfusion medicine. Several transfusion medicine curricula have been proposed, including those developed through the Transfusion Medicine Academic Awards (TMAA). To our knowledge, no comprehensive study has assessed how transfusion medicine is incorporated into undergraduate medical education. ⋯ Transfusion medicine content in American undergraduate medical education is variable and the influence of the TMAA program on contemporary medical school curricula is questionable. Future efforts in this area should focus on standardizing and improving undergraduate medical education in transfusion medicine.
