[Achievement quality evaluation of pretransfusion bedside test]

As far as transfusions accidents are concerned, immunological causes are frequent. Pretransfusion Bedside Compatibility Tests (PBCT) are the last chance to avoid them. However low data are disponible on the quality their realisation is achieved. The aim of the study is to evaluate the quality level of achievement of these tests, in HIA Laveran Hospital (Marseille Armees, France). During 13 months, from november 2001 to december 2002, we systematically analysed PBCT after use (analysis rate 91%). Three kinds of errors have been noticed: Technical errors, understanding errors and both. Overall mistake rate was 10.4% (1632 tests analysed). In the same time, a complementary formation was dispensed to users responsible of misfits. This formation was successful, decreasing the overall mistake rate from 22.8% (november 2001) to 10.7% (december 2002). This study is an evidence of the importance to evaluate achievement quality of PBCT and shows how efficient can be simple correction methods.
