Abstract
In an attempt to improve transfusion-related procedures at our hospital, the effects of introducing of Type and Screen (T & S) were investigated.Subjected to study were 4978 requests for RBC, 1171 requests for PC, 3518 requests for FFP, 388 requests for 0 units, and 952 requests for elective surgical procedures during the 15-month period from January 1988 to March 1989.In order to prevent transfusion accidents, all patients data were controled using a personal computer.The execution rate of T & S amounted to more than 80%, and 41% of the operative cases having requests for 0 units transfusion.The introduction of T & S enabled us to omit minor crossmatching and anti-globulin tests for RBC and performed non-crossmatch tests for additional surgical blood, PC and FFP.There was a decrease of 16.2% in the rate of consumption of anti-globulin serum. C/T ratio and rate of returning blood showed decreases of 30% and 21%, respectively. A contribution was also made to decreases of 17 and 71% in warehousing and returning concentrated RBC units from red cross blood center, respectively. Blood delivery time could be shortened to within 5minutes for additional surgical blood, FFP and PC and within 30minutes for RBC.T & S was found to not only help smooth our hospital's blood supply system, but also to contribute to a reduction in due waste of manpower and of reagents. Overall, it is though to be an excellent method.
