This measure will have a total of five performance rates: one for each of the four selected blood conservation strategies as well as a fifth, overall performance rate. The rates are described below: Rate 1: Lysine Analogues: Percentage of denominator-eligible patients for whom lysine analogues were used Rate 2: Mini-circuits, RAP, or ultrafiltration: Percentage of denominator-eligible patients for whom mini-circuits, or Retrograde Autologous Priming (RAP) or ultrafiltration were used Rate 3: Red Cell Salvage using Centrifugation: Percentage of denominator-eligible patients for whom red cell salvage using centrifugation was used Rate 4: Transfusion Algorithm with Point-of-Care Testing: Percentage of denominator-eligible patients for whom a transfusion algorithm supplemented with point-of-care testing was used Rate 5: Composite Performance Score: Percentage of denominator-eligible patients for whom a cumulative score of 100% of blood conservation strategies was met
