A comparison of preoperative blood orders in the pre-MSBOS / EBRS and post-MSBOS / EBRS time periods among all surgical patients. (A) The percentage of patients who received type and screen and type and crossmatch orders decreased while the percentage of patients with no preoperative blood orders increased. (B) This change in practice was associated with a small increase of one additional patient per thousand that required emergency release type-O, uncossmatched erythrocyte transfusion. EBRS = remote electronic blood release system, MSBOS = maximum surgical blood order schedule.
