The Verpleegkundigen & Verzorgenden Nederland Verpleegkundig Specialisten (V&VN VS), the Dutch professional organisation representing nurse practitioners, has introduced a requirement for advanced practice (registered) nurses (APRN) who wish to be eligible for reregistration within five years to participate in a peer review group for at least eight hours per year. In 2013, five APRNs caring for people with haemophilia and other bleeding disorders in the Netherlands formed a peer review group. As no framework was available, research was undertaken through reviewing literature and engaging in exploratory discussions within the profession in order to identify best practice in establishing such a group. The initial meeting of the new peer review group agreed possible methodologies and established meeting rules. After four meetings, some initial conclusions can now be drawn on the benefits of this specialised haemophilia peer review group. Overall, it is clear that participation in a forum in which knowledge and expertise are shared, contributes to the professionalism of the APRN.
