Randomized to transfusion Hgb trigger of 7 or 10 (restrictive vs. liberal)
All results favored the restrictive (Hgb 7) strategy

Minimize blood draws
Iron and nutrition
Non Heme blood products used only as indicated for bleeding, with point of care testing (TEG!)
A Single Dose of platelets (adult: one apheresis product) generally recommended as it increases the platelet count by 30,000- 60,000/ µl
Platelet count ≤ 10,000/ µL
Platelet count ≤ 20,000/ µL and signs of hemorrhagic diathesis
Platelet count ≤ 50,000/ µL in a patient with active hemorrhage
Platelet count ≤ 50,000/ µL in a patient with invasive procedure (recent, in-progress, planned)
Platelet count ≤ 100,000/ µL in a patient with bleeding in a closed anatomical space (eg. CNS)
Platelet dysfunction with active or anticipated hemorrhage (TEG?)
Despite the development of RBC guidelines and the Epic BPA, the vast majority of RBC transfusions (60%) continue to occur at a Hgb of 8 or above
Increased guideline adherence will
Follow the RBC and Platelet guidelines developed by the Blood Task Committee and endorsed by the Medical Staff leadership
Transfuse a single unit of platelets
Communicate this expectation to your peers and to your house staff
Incorporate the blood guidelines, and the clinical reasoning behind them, into the teaching and communication provided to interns and residents
Direct feedback or questions to Blood Task Force regarding adoption of guidelines
