Impact of Patient Blood Management on Red Blood Cell Utilization in an Urban Community Teaching Hospital: A Seven-Year Retrospective Study

Abstract

Objectives: This study aimed to showcase how implementing a patient blood management (PBM) program effectively cuts unnecessary red blood cell (RBC) transfusions in a New York City urban community teaching hospital. Methods: Analyzing seven years from 2013 to 2019, a retrospective review of RBC transfusions was conducted. Results: Following the introduction of PBM, considerable improvements were observed annually. These included a drop in mean pretransfusion hemoglobin levels from 7.26 g/dL (2013) to 6.58 g/dL (2019), a 34% reduction in yearly RBC unit transfusions, and fewer units given to patients with pre-Hgb levels ≥ 7 g/dL (from 1210 units in 2013 to 310 units in 2019). Furthermore, this study noted a decline in two-unit RBC orders when Hgb levels were ≥ 7 g/dL from 65 orders in 2013 to merely 3 in 2019. The estimated total cost savings attributed to the six-year PBM program duration after full implementation in 2014 amounted to USD 2.1 million. Conclusions: Overall, PBM implementation significantly decreased RBC transfusions and enhanced transfusion practices. The findings emphasize that successful PBM strategies do not always necessitate extensive resources or increased budgets but instead rely on the application of intuitive methods, as evidenced by this study.
