Evaluate the appropriateness of platelet transfusion order for the following clinical scenario: 1 platelet unit is requested for a 63-year-old male with a history of alcohol-induced end stage liver disease with ascites who presents for paracentesis. His platelet count is 47 x 109/L.

This order does not seem appropriate. A platelet count of >20K/uL (20 x 10^9/L) is adequate for a minor procedure. However, a patient with liver failure may be coagulopathic and have increased bleeding risk, therefore appropriate assessment and monitoring is warranted.

Calculate the CCI after transfusion of a platelet unit in a 72-year-old male patient with acute myeloid leukemia status post-induction chemotherapy. His pre- and post-transfusion platelet counts are 8 and 18K/mL, respectively. His BSA is 1.6m2.
