A survey of blood component use in a German university hospital.

BACKGROUND: There are no recent studies on transfusion practice and blood use with regard to diagnoses of European recipients. We conducted a survey of blood component use, including packed red cells, fresh-frozen plasma, and platelets, in an acute-care university hospital in the Greater Nürnberg area. STUDY DESIGN AND METHODS: A survey was carried out of blood component transfusion at a university hospital (Erlangen, Germany) between June 1994 and May 1996. Transfused units were listed by broad diagnostic categories formed from principal diagnoses of the recipients according to the International Classification of Diseases, Ninth Revision.
RESULTS: Among 100,497 discharged patients, 6,590 patients who received transfusion (6.6%) are represented in this survey. Of 28,440 red cell units and 8,592 fresh-frozen plasma units, 72.4 percent and 66.9 percent, respectively, were used in patients with neoplastic diseases, circulatory system diseases, or disorders of the digestive system. Of 2704 platelet units, 78.1 percent were transfused to patients with neoplastic or gastrointestinal diseases or diseases of blood-forming organs. These four diagnostic categories accounted for 77.7 percent of all costs of transfusion therapy. Males received 60.1 percent of all blood components transfused, and patients less than 65 years old received 68.0 percent.
CONCLUSION: This survey provides information on blood component usage in a German university hospital. It demonstrates the concentration of today's blood utilization among a few diagnostic categories. The study shows that detailed information on local blood use may be obtained quickly by using data available from transfusion services and medical record departments. This information is relevant for quality management of transfusion practice, cost analyses and for planning local and regional blood donation programs.
