Learning from regional differences. Online platform: http://www.versorgungsatlas.de

In 2011, the Central Research Institute of Ambulatory Health Care in Germany (ZI) published the website http://www.versorgungsatlas.de, a portal that presents research results from regional health services in Germany. The Web portal provides a publicly accessible source of information and a growing number of selected analyses focusing on regional variation in health care. Each topic is presented in terms of interactive maps, tables, and diagrams and is supplemented by a paper that examines the results in detail and provides an explanation of the findings. The portal has been designed to provide a forum on which health service researchers can publish their results derived from various data sources of different institutions in Germany and can comment on results already available on http://www.versorgungsatlas.de. For health policy actors, the discussion of regional differences offers a new, previously unavailable basis for determining the region-specific treatment needs and for providing health-care management with the goal of high-quality care for each resident.
