Table 4. Quality indicators in surgical specialties.
In surgical specialties and super-specialties, blood utilization indices varied so widely with general surgery department showing best and ENT department showing worst red cell ordering, issuing and utilization practices.
CTR: Crossmatch-to-transfusion ratio [6]; %T: Transfusion probability [7]; TI: Transfusion index [7]; UR: Utilization rate.
An asterisk (*) indicates that the target value for the utilization rate has not been defined in the literature. Although a few studies have calculated the utilization rate, the target value has not been discussed [8].
