Economic issues in European self-sufficiency.

Future clinical practice in haemophilia care must make optimum use of resources and provide the highest quality products and services in an efficient and effective manner. Studies show that prophylactic therapy, compared with on-demand therapy, results in less time off work--that is, a smaller loss in productivity. However, prophylactic therapy requires a three- to five-fold greater annual amount of factor VIII than does on-demand therapy. Further study is needed to determine the optimum therapeutic strategy that gives the best cost v. benefit situation.
