P12 An Audit of Fresh Frozen Plasma Transfusion Use in the Royal Hospitals Trust (RGHT)

Allogeneic fresh frozen plasma (FFP) transfusions have increased in recent years, in the Royal Group of Hospitals Trust and in the UK as a whole. In the 2003 Serious Hazards of Transfusion report, FFP was the blood product most commonly attributed to the development of transfusion associated acute lung injury and a leading cause of transfusion related mortality. In the British Committee for Standards in Haematology (BCSH) guidelines there are few indications for FFP transfusion. Stainsby found that appropriateness of FFP transfusion in England varied from 62–92%. Audit objectives (i) To assess the appropriateness of FFP transfusions in the RGHT against BCSH guidelines ‐ 100% standard; and (ii) To assess the adequacy of documentation for FFP transfusion episodes re indication for transfusion and clinical effectiveness ‐ 100% standard. Method Data relating to FFP transfusion episodes between October 2004 and January 2005 inclusive, was extracted retrospectively from available patient notes by an SpR in haematology and a consultant anaesthetist. Anonymously completed proformas were jointly assessed for appropriateness of transfusion by the same investigators.FFP transfusion episodes Appropriate Inappropriate137 episodes (114 patients) 93 (68%) 44 (32%) Reversal of warfarin effect, bleeding not severe or absent 16 Hepatic disease induced coagulopathy, no bleeding 6 Heparin/antiplatelet induced coagulopathy, with bleeding 4 Other causes of coagulopathy without bleeding 13 Ongoing blood loss, normal coagulation screen 4 Normal coagulation screen, no evidence of bleeding 1 Clinical documentation Present Absent Statement re indication for FFP transfusion 73 (53%) 64 (47%) Statement re clinical effectiveness of transfusion 52 (38%) 85 (62%)Conclusion and Recommendations A significant number of FFP transfusions are inappropriate, based on recent BCSH guidance. Documentation in clinical notes concerning the indication and response to FFP transfusion is frequently lacking. Appropriateness of FFP transfusion and associated clinical documentation should be improved by staff education and greater awareness of BCSH guidelines. Education should also include appropriate monitoring and management of bleeding secondary to warfarin or antiplatelet therapy. FFP transfusions should be re‐audited 1 year hence.
