"The Norwegian Adult Mental Health Registry" (NAMHR) is a medical quality register collecting and systematizing data on patients and their treatment in specialist mental health care for adults in Norway. The main purpose is to create a documentation basis for quality assurance, evaluation, and improvement of assessment and treatment for patients who are offered treatment for mental disorders in the specialist health service. The register uses automatic data capture from various existing data sources. New patients are automatically included, but given the opportunity for reservations from the register without affecting their services and treatment.
