Appropriateness of platelet, fresh frozen plasma and cryoprecipitate transfusion in New South Wales public hospitals.

Objectives: To estimate the appropriateness of transfusions of platelets, fresh frozen plasma (FFP) and cryoprecipitate using National Health and Medical Research Council and Australasian Society for Blood Transfusion guidelines (NHMRC/ASBT 2002).

Main Outcome Measures: Proportion of potentially inappropriate transfusions.
