A Survey Of Autologous Blood Transfusion Practices In Germany

This survey was designed to evaluate the use of autologous blood transfusion techniques in Germany in 2000 and to identify how the use of these techniques has changed over the past 5 years.Questionnaires were mailed to the chief anaesthesiologists of 400 randomly selected German hospitals with greater than or equal to25 surgical beds. Information was sought about the current and past use of preoperative autologous blood donation (PABD), acute preoperative haemodilution and peri-operative blood salvage. Data were requested for the calendar year 2000.Three hundred and forty-three (86%) completed questionnaires were returned. PABD, haemodilution and peri-operative blood salvage were used by 85, 54 and 67% of respondents, respectively. Thirty-seven per cent of PABD users reported that PABD use declined, 28% reported that it increased and 34% reported that it remained unchanged over the past 5 years. The proportions of those reporting declining vs. increasing use of PABD did not differ significantly (P=0.09). Sixty per cent of users of haemodilution reported that its use declined, 10% reported that it increased and 29% reported that it remained unchanged over the past 5 years. Sixteen per cent of hospitals that were equipped with cell-washing devices reported that the use of these devices declined, 47% reported that it increased and 37% reported that it remained unchanged over the past 5 years.The results indicate that autologous blood transfusion techniques were widely used in Germany in 2000, with PABD being the most common technique. The use of PABD did not change significantly, the use of haemodilution declined markedly and the use of peri-operative cell salvage increased markedly during the past 5 years before the survey.
