How do I reduce variation in red blood cell transfusion practices in a large integrated health care system?

Abstract

Background: Reducing variation in transfusion practices can prevent unwarranted transfusions, an outcome that improves quality of care and patient safety, while lowering costs and eliminating waste of blood. We developed and assessed a system-wide initiative to reduce variation in red blood cell (RBC) transfusion in terms of both transfusion utilization and the number of units transfused. Intervention Design And Methods: Our initiative combined a single-unit default order for RBC transfusion in hemodynamically stable, non-bleeding patients with a “Why Give 2 When 1 Will Do?” Choosing Wisely campaign, while also promoting a restrictive hemoglobin threshold (Hb <7 g/dl). This multimodal intervention was implemented across an academic medical center (AMC) with over 950 beds and 10 community hospitals. Results: Between our baseline (CY 2020) and intervention period (CY 2021), single-unit orders increased from 57% to 70% of all RBC transfusion orders (p
