Development of permanent national register of blood component use utilizing electronic hospital information systems

Abstract

We wanted to establish a permanent national database system, which can be utilized to study transfusion recipients and blood use in Finland. A regularly updated register for permanent use was developed. To study the usability of the database, years 2002 and 2003 were further analysed. Database included all transfused patients in major blood-transfusing hospitals from four university and five central hospital districts managing altogether 63% of Finnish inpatient hospital episodes. Audit of gathered data reveal 96.8% match in adult blood components with Finnish Red Cross, Blood Service sales figures. Model data set includes 59,535 transfused patients (44.3% men and 55.7% women) having received 529,104 blood components. Half of all blood units were transfused in connection with surgical operations. Most of the blood recipients were elderly (51.6% are over 64 years of age). Blood-component use and transfusion-related costs varied widely between hospitals. Hospital data managing systems can be useful for creating a population-based database system to monitor and compare transfusion practices. This record provides information about transfusion epidemiology for transfusion professionals, hospital management, and hospital administration.
