An Approach to Blood Utilization in Elective Surgery at Chaophayayomraj Hospital

Abstract

The number of requests for blood transfusion in patients on the elective surgery is currently expanding, which may be resulted in the shortage of blood supply. The implementation of three-index blood utilization management including crossmatch-to-transfusion (C:T ratio), transfusion probability (%T) and transfusion index (Ti) is suggested. To study an approach to blood utilization in elective surgery at Chaophayayomraj Hospital.

Materials and Methods: 5 months retrospective data in demographics and blood requests of patients on the elective surgery was collected. Three-index blood utilizations of C:T ratio, %T and Ti were analyzed.

Results: There were 1,304 patients on the elective surgery and the total blood requests were 2,359 units. Only 263 patients with 494 units were transfused (C:T ratio = 4.78, %T = 20.2, Ti = 0.37). The highest blood requests were patients in Orthopedics (C:T ratio = 2.99, %T = 27.8, Ti = 0.53), followed by patients in General surgery C:T ratio = 5.55, %T = 19.25, Ti = 0.35) and patients in Obstetrics and Gynecology (C:T ratio =17.9, %T = 6.25, Ti = 0.11). When type and screen were compared with complete crossmatch, the total cost of blood preparation was reduced, 102,080 bath were saved and reduce job 234 hours

Conclusion: This retrospective study showed the over blood ordering in elective surgery at Chaophayayomraj Hospital. The appropriate and effective blood utilization should be used to reduce resources and the cost of blood preparation and to provide flexible utilization of blood stock, especially in emergency situations.
