Platelet transfusions in adult patients with particular reference to patients undergoing surgery

Le résumé fourni par la source

Descriptive information on platelet (PLT) recipients, particularly during surgery, is limited. A description of the current epidemiology of PLT-transfused patients is required to optimize platelet transfusion care and to follow trends in PLT use. In 2004 and 2005, information was combined from several computerized medical systems. Participating hospitals (9 hospital districts of 21) handled approximately 64% of annual Finnish hospital admissions. A total of 6321 adult patients were transfused with 37,761 PLT products. Most PLT products (43.1%) were transfused to patients suffering from haematological malignancies. Only 1.0% of all surgical patients received PLTs (53.8% of PLT recipients and 35.8% of transfused PLTs). The most common single operation connected with PLT transfusion was coronary artery bypass while 27.1% of surgery-related PLTs were given to patients having an operation involving the digestive system or spleen. Only 36.4% of all PLT-transfused (operated and conservatively treated) patients were discharged directly home; in-hospital mortality was 9.5%. PLTs were given 40 products per 1000 hospital admissions requiring an operation in 2004, and 38 products in 2005. Perioperative PLT use is slightly decreasing in adult patients. As a single-operation type, coronary artery bypass patients receive most of the PLT products and have experienced no decline in PLT use over the years. Overall, PLT recipients have high in-hospital mortality.
