The day\u2010to\u2010day practice of ordering red blood cell (RBC) inventory usually involves manually comparing current inventory levels with predetermined thresholds calculated from historical usage and ordering the difference. To date, there have been no published methods for ordering RBC inventory based on laboratory characteristics of admitted patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>STUDY DESIGN AND METHODS<\/jats:title><jats:p>We designed and implemented a blood ordering algorithm to provide a more accurate measure of predicted RBC utilization in our institution. Cerner Command Language (Cerner Millennium) was used to extract and combine historical RBC unit usage, current inventory levels, and system\u2010wide hematology values and blood groups. This report contains a suggested order based on current inventory, historical inventory data, ABO group, and the current \u201canemia index\u201d for the institution.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The mean daily total RBC inventory was significantly reduced after implementation (401.7\u2009units vs. 309.0\u2009units, p\u2009&lt;\u20090.05). There was a significant reduction in monthly RBC outdates in this period (19.1 vs. 8.1, p\u2009&lt;\u20090.05). The age of RBCs at time of transfusion was reduced as well.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>We developed a novel algorithm that automatically generates a suggested RBC inventory order using real\u2010time hospital\u2010wide survey of patient ABO typing, hematology values, and historical data. After implementation of the algorithm we demonstrated a significant reduction in daily inventory levels and RBC outdate
