Background: Despite the lack of evidence, there continues to be significant prophylactic use of plasma for mildly elevated INR (≤2.0). In an effort to bridge the gap between guidelines and actual clinical practice, a blood management initiative was implemented at our institution aimed at developing more effective educational strategies to increase understanding and compliance with evidence based guidelines. This quality study was designed to evaluate the effect of targeted education towards changes in 1) the overall use of FFP 2) the indications cited for transfusion of plasma, and 3) utilization practices of individual clinical services.
Design: Data was collected retrospectively for one month periods before (June 2010) and after (June 2011) the implementation of educational strategies, which included reporting the June 2010 data in a medical staff newsletter, individual meetings with clinical departments, (focusing on specialties with the most plasma usage for minimally invasive procedures [medicine]) and invitation of guest presenters with expertise in blood management. Plasma transfusion data was abstracted from the laboratory information system, and the following information was collected for each transfusion: pre-transfusion INR, ordering clinical service (cardiothoracic surgery, surgery [including all other surgical specialties], or medicine [GI, ER, internal medicine and critical care]), and indication for order (significant hemorrhage, emergency reversal of warfarin, or prophylaxis prior to procedure [PPP]).
|INR ≤2.0||107 (49.5%)||124 (46.6%)|
|INR ≤2.0 and indication PPP||68 (31.5%)||72 (27.1%)|
