Overview What is evidence based care (EBC) ? What are the key components of EBC? Is the EBC framework a value for hemophilia? Can the EBC framework be applied to haemophilia? Can EBC guidelines be issued in hemophilia? Is the hemophilia community going toward EBC?
21
Why would the hemophilia community embrace EBC? Evolving scenario - challenges – Hemophilia has been a prototype has been the betrayal of the dream of a cure for a male’s disease in the roaring ‘60es of the infinite power of progress – Many more rare diseases with more expensive treatment learning to advocate for their treatment in absence of alternatives – Different economical models landing on the stage
22
Why would the hemophilia community embrace EBC? Evolving scenario - opportunities – Hemophilia Strong and widespread network of HTC, NMO, patients Rare, but sizeable disease – many less patients studied that one could Long tradition of collaboration among all relevant stakeholders

WFH guidelines Srivastava, A, Brewer, A, Mauser-Bunschoten, E.P., Key, N.S., Kitchen, S., Llinas, A., Ludlam, C., Mahlangu, J.N., Mulder, K., Poon, M.C. & Street, A. – Haemophilia 2013, 19, e1–e47. 3. Examination of Guidelines [ from the IQWIG Rapid Report ] – There are 13 treatment guidelines. Only three are evidence based. But most of the guidelines are in line with the results of the report. – The WFH treatment guidelines from 2012 were considered as “not evidence based”
