We have estimated the average annual cost per patient with DMD in eight European countries adopting a social perspective, and to our knowledge this is the first study with such a wide perspective. The results on costs show a considerable gap between Eastern and Western European countries. Non-healthcare costs range from 64 to 89 % of overall costs and informal care is to a great extent the main driver of this cost category. The HRQOL of people with DMD is much lower than that of the general population.

We have shown that haemophilia is associated with a substantial economic burden and impaired HRQOL. Studies on cost of illness and HRQOL are important for haemophilia as the future of this disease is likely to change with the development of new innovative treatments. The introduction of these treatments will most likely impact future costs related to haemophilia.

Value-based pricing (VBP) is well established in markets for common goods and services, but wide consensus on VBP for pharmaceuticals is lacking. In principle, VBP implies that prices are mainly driven by a drug's value (value for money) and that the impact on budget (sustainability) is a second-order driver of price regulation. Although the literature provides descriptive analyses on regulations governing medicine price negotiation, there are few insights on whether and how price negotiation regulations have been implemented. The goal of this article was to cover this information gap for 5 European countries and the United States. VBP has been applied according to two models: (1) direct models in which cost-effectiveness is a driver; and (2) indirect, multi-attribute models characterized by greater discretion on the integration between the different value domains and the evaluation of consistency between costs and value. In these models, cost-effectiveness is not a driver. In addition, it is hard to evaluate within these models the actual implementation of VBP. Identifying whether and how VBP is applied requires a clear predefined link between added value and the premium price, as well as transparency in the way added value is converted into a premium price. In general, for these countries, it remains difficult to determine whether pricing is mostly driven by value (value-for-money) or impact on budget (sustainability). In instances in which thresholds on the incremental cost-effectiveness ratio are used, it becomes easier to understand whether VBP has been implemented. If VBP relies on a multicriteria approach, greater transparency on which criteria have been used to assess a new drug and how they have been converted into a reasonable price may help in understanding whether a value-based approach has been used.
