Blood ordering practices from the periods before and after release of the updated, institution-specific maximum surgical blood order schedule (MSBOS) and remote electronic blood release system (EBRS) were implemented in July 2012. (A) Among patients undergoing surgical procedures in the “no sample needed” category of the MSBOS, blood orders considered to be unnecessary (type and screen and type and crossmatch combined) decreased by 38.1%. (B) For all surgical cases, blood orders decreased by 17.8%. (C) For all hospitalized patients, there was a concomitant decrease in the crossmatch-to-transfusion ratio (C/T ratio).
