Comparative Study
An analysis of blood utilization for elective surgery in a tertiary medical centre in Malaysia.
The purpose of this study is to determine the efficiency of blood utilization for elective surgery at the University of Malaya Medical Centre (UMMC). A similar study conducted six years earlier in the same unit resulted in the introduction and implementation in December 1997 of the local Maximum Surgical Blood Order Schedule (MSBOS) and the Group Screen and Hold (GSH) procedure instead of a full crossmatch. This paper compares the findings of the current study with that conducted earlier. ⋯ The introduction of MSBOS and GSH has led to a significant decrease in the percentage (p= < 0.05) of cases for which a full crossmatch is done. The conservation policies have led to a decreased crossmatch workload and reduced blood outdating. Although the CT ratio has improved for many individual procedures, the overall CT ratio in fact increased from 4.4 to 5.0. There remains therefore, a continuous opportunity to improve transfusion practices by reviewing the local MSBOS. The transfusion index (TI) calculated for each procedure in this study can be utilized to recommend a GSH for those procedures with low TI.
