A multifaceted strategy to reduce inappropriate use of frozen plasma transfusions in the intensive care unit

Purpose: The purpose of this study is to determine the effect of a multifaceted behavior-change strategy on inappropriate use of frozen plasma (FP) transfusions in the intensive care unit (ICU). Materials and Methods: A prospective, time-series study was conducted in a 15-bed medical-surgical ICU in 3 phases: (1) baseline observation; (2) educational campaign, audit and feedback to prescribers, and implementation of an FP request form; and (3) FP request form only. Independently, in triplicate and blinded to study phase, appropriateness of each FP request was adjudicated based on published guidelines and clinical context. Results: Over the 15-month study period, 626 FP transfusions (210 FP requests) were administered to 88 patients. Inappropriate FP requests decreased slightly from phases I to III (60% vs 46%; P = .09), FP requests that were consistent with the guidelines did not change (23% vs 22%; P = .86), and FP requests that were appropriate for the ICU yet inconsistent with the guidelines increased (17% vs 32%; P = .04). Although uptake of the FP request form decreased in phase III, it was associated with fewer inappropriate transfusions. Conclusions: The behavior-change strategy modestly improved appropriate use of FP transfusions in the ICU. Improving FP request form accuracy, completeness, and compliance may be required to achieve maximum effect and ensure sustainability. (C) 2011 Elsevier Inc. All rights reserved.
