[Patient based care registries as a tool to follow up services].

The Federation of Swedish County Councils and six medical specialties are working together in a project aiming to support and stimulate the development of patient based case registers as a tool to follow up, evaluate, develop and manage medical units. The project is based on participation on the part of the medical professions in a process-oriented way. Each case register shall be based on the individual patient, and will integrate inpatient and outpatient care, all medical professions and important procedures.
