Background : Patients undergoing elective orthopedic surgeries often incur excess blood loss necessitating transfusion. The preoperative placement of blood requests frequently overshoots the actual need resulting in unnecessary crossmatching. Aims : Our primary goal was to audit the blood utilization in elective orthopedic surgeries in our hospital over a 1-year period and recommend a blood ordering schedule. Materials and Methods : A retrospective analysis of patients who underwent elective orthopedic surgeries over a period of 1 year was done. The data collected include patients' age, sex, type of surgical procedure, pre- and postoperative hemoglobin (Hb) levels, number of units crossmatched, returned, transfused, crossmatch to transfusion ratio (C:T), transfusion indices, estimated blood loss for each surgical procedure, and the actual and predicted fall in Hb. We propose a blood ordering schedule based on surgical blood ordering equation. Results and Conclusions : A total of 487 patients with a median age of 37±17 years (mean ± standard deviation) were evaluated. One thousand three hundred and seventy-seven units of blood were crossmatched and only 564 units were transfused to 260 patients. Fifty-nine percent of the units crossmatched were not transfused. Six of the 12 elective procedures had a C:T ratio higher than 2.5. Ten of the 12 procedures (83.3%) had a low transfusion index (TI < 0.5). The calculated red blood cell units were less than 0.5 in 5 of the 12 elective procedures, and hence we recommend a group and save policy for these procedures. Blood ordering schedule based on patient and surgical variables would provide an efficient way of blood utilization and management of resources.
