Extended Follow-up of an Educational Intervention Encouraging Appropriate Use of Blood Transfusions.

A restrictive transfusion strategy of packed red blood cells (PRBCs) has been associated with at least non-inferior patient outcomes in a variety of clinical settings. In December 2014, we conducted an educational intervention which consisted of an oral presentation and computerized notifications at a single tertiary medical center. The aim of this study was to examine the long-term effects of a simple and low-cost educational intervention aimed to promote awareness to transfusion guidelines. We retrospectively analyzed all PRBC transfusions ordered between 2014 and 2017. The primary end point was defined as the percentage of PRBC transfused to patients with hemoglobin (Hb) ≥8 g/dL. Between 2014 and 2017, a total of 27,475 PRBCs were transfused in our medical center. There was a continuous reduction in the percentage of PRBCs transfused at a Hb level ≥8 g/dL between 2014 and 2017, with a matching increase in the PRBC percentage trans-fused at Hb <7 g/dL (OR reduction of 42%, 95% CI 0.54-0.62 and OR increase of 68% [95% CI 1.56-1.81], respec-tively). A simple educational intervention likely contributed to sustained improvement in the appropriateness of PRBC transfusions.
