Funded Activity Summary

Haemophilia A and B are genetic conditions which affect 1 in 7,000 males in Australia. These disorders cause frequent bleeding due to problems with the clotting factor in blood. Over the past decade there has been a move to administer clotting factor to children with haemophilia in order to prevent bleeds and the consequent damage to joints that occurs when bleeds occur in a joint. Participation in vigorous physical activity and sport is thought to increase the risk of bleeding. Because of this, children are often given clotting factor prior to playing sport. However clotting factor is extremely expensive. For example, a boy wanting to play tennis three times a week would require three injections of cIotting factor per week at a cost of approximately $250,000 a year. To date there is no good evidence about which physical activities are likely to increase the risk of bleeding. If this information was available clinicians would be able to optimise timing of administration of clotting factor so that it is administered prior to activities associated with high risk of bleeds. Another reason to quantify risk of bleeds associated with activity is to inform decisions about participation in physical activity. Every boy with haemophilia wants to know if he can play sport or ride a skateboard or jump on a trampoline. Informed decisions about participation require accurate estimates of risk. This study will use an innovative design to provide, for the first time, accurate estimates of the risk of bleeding associated with physical activity. This information will form the basis for clinical practice guidelines regarding participation in physical activity.
