RESUMEN
A Registry of inherited bleeding disorders was set up in the Region of Emilia-Romagna (RER) to collect information about these diseases and to improve the quality of care. From January 2003, the eight Haemophilia Centres (HC) in the RER began to use computerized clinical records; every 6 months, they send data to Parma Hospital to be processed and published in a website (http://www.registroemofiliarer.it). Great efforts are made to ensure high quality of data. Results of general interest are included in a free 'public area' and more sensitive data in a 'reserved area' (open only to HC and to health authorities). A total of 610 individuals are included: 249 haemophilia A (HA), 63 haemophilia B (HB), 173 von Willebrand's disease, 69 rare bleeding disorders, seven platelet disorders and 49 haemophilia carriers; 131 were genotyped, 188 were tested for inhibitors (16 affected). The most frequent bleeding was haemarthrosis. The joint score (evaluated in 104 haemophiliacs) was higher in severe HA. There were 22 HIV-positive and 182 hepatitis C virus-positive patients (21% have chronic hepatitis, two hepatocellular carcinoma). In 2005, two patients received primary prophylaxis, 47 secondary prophylaxis, four children were on immune-tolerance induction. From 2003 to 2005 the use of recombinant products was greatly increased and the majority of patients received them. The mean clotting factor consumption for prophylaxis was higher than on-demand treatment. The main features of registry are to collect high quality and comprehensive data of all patients followed by HC, to improve quality of care and it's availability on the web.
