PURPOSE OF REVIEW: Platelet transfusion remains a challenging procedure. Concerns about bacterial contamination and other complications, and the interest in improving the evidence base for criteria for platelet transfusion thresholds and policies have provided impetus for studies that challenge the status quo. The current review highlights recent studies and reviews which address these questions in innovative and thoughtful ways.
RECENT FINDINGS: Randomized controlled trials have determined that prophylactic platelet transfusions for the prevention of bleeding in chemotherapy and hematopoietic stem cell transplant patients are superior to a therapeutic approach. For the treatment of immune refractoriness, an observational study identified that of the two main ways to treat, the provision of human leukocyte antigen-matched or cross-matched platelets, neither appears to be as effective as previously believed. When emergent reversal of antiplatelet medications is desired, platelet transfusion is common, however the evidence as to the benefit of this practice is indeterminate. ABO plasma-incompatible platelet transfusion remains a challenge as this product may pose an increased risk for hemolysis. Low-anti-A, anti-B titered products are encouraged, but are not routinely available.
SUMMARY: Platelet transfusion practices are being questioned more than ever before. As we develop better therapies and guidelines, the practice of platelet therapy can be expected to change in the near future.
