Haemophilia nurses in the UK are instrumental in supporting people with haemophilia in self-management, including managing treatment options, recording treatment use and understanding the budgetary impact of prescribing practice. The widespread use of prophylaxis identified haemophilia as a high cost disorder to treat, resulting in a financially successful national tendering process with increased scrutiny of clotting factor use at both individual and haemophilia treatment centre level. The UK tenders, undertaken at a national level every three years, have ensured access to current and new therapies at the most cost-effective price through economies of scale in committing to purchase large volumes from suppliers.
