Hospitals, Krankenhäuser, in the Ruhr form part of the relatively well-funded, combined public and private German health care setup. This is supported by high taxes from the social system. Some of the shortest waiting times in Europe can be found and a level of professionalism that is often to be envied.

Whether founded more recently or a century and a half ago, clinics and hospitals normally have a good reputation. Many are defined by a certain specialisation, while some are renowned.
