title: A national survey of transfusion-related acute lung injury risk reduction policies for platelets and plasma in the United States.
abstract: BACKGROUND
  Little information exists on the specific transfusion-related acute lung injury (TRALI) risk reduction practices used by multiple blood collecting institutions in the United States.
  
  
  METHODS
  An AABB-appointed TRALI working group designed a set of questions about TRALI risk reduction for platelets (PLTs) and plasma. AABB member institutions were asked to respond via an Internet-based survey during a 3-week period in August through September 2009.
  
  
  RESULTS
  Valid responses were received from 47 US blood centers (accounting for 1.57 million apheresis PLT units and 3.15 million whole blood-derived transfusable plasma units) and 56 hospital blood collectors. Among the blood centers, 87 and 98% had initiated some PLT and plasma risk reduction, respectively. HLA antibody testing of plateletpheresis donors was performed by 20 (43%) blood centers. There was substantial variation in the number of pregnancies (from one to more than four) that triggered testing and most centers did not screen based on a transfusion history. Almost all centers had policies to redirect HLA antibody-positive donors to whole blood donation and to potentially retest HLA antibody-negative donors. There were no blood centers performing HNA antibody testing. Sex-based risk reduction policies for plasma included all male, or predominantly male, and never-pregnant females; these varied by blood center, blood group, and method of plasma collection. A majority of centers indicated increased production of plasma frozen within 24 hours after phlebotomy.
  
  
  CONCLUSIONS
  Almost 3 years after the publication of the initial AABB bulletin on this issue, TRALI risk reduction strategies are commonly employed at most US blood centers. However, procedures are not uniform.
