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

Abstract

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). DESIGN AND SETTING: Three separate retrospective surveys of medical records from 1 January to 31 August 2000 (1147 transfused patients) from 14 hospitals selected randomly from all public hospitals that use these blood products in New South Wales: five tertiary referral, five major metropolitan, and four major rural (base) hospitals. MAIN OUTCOME MEASURES: Proportion of potentially inappropriate transfusions. RESULTS: 33% (136/414) of platelet, 37% (248/669) of FFP and 62% (37/60) of cryoprecipitate transfusions were assessed as inappropriate. By hospital type, 29% (75/259) of platelet transfusions were inappropriate at tertiary referral hospitals, 51% (40/78) at major urban hospitals, and 27% (21/79) at major rural hospitals. For FFP, 36% (112/313), 37% (80/216) and 39% (55/140) were inappropriate for referral, urban and rural hospitals, respectively. Cryoprecipitate was used almost exclusively at tertiary referral hospitals. CONCLUSIONS: In terms of the NHMRC/ASBT guidelines on use of blood products, there is considerable inappropriate transfusion of platelets, FFP and cryoprecipitate in NSW public hospitals.
