The large number of national laws involved is partly due to the fact that the Directive regulated a number of issues which are under different regional/administrative levels and in separate pieces of legislation in Member States, such as reimbursement mechanisms, information channels (National Contact Points, healthcare providers), patients' rights and entitlements, professional liability.
Au rang de ces questions figurent, entre autres, les mécanismes de remboursement, les canaux d'information (points de contact nationaux, prestataires de soins de santé), les droits des patients et la responsabilité professionnelle.
