[Verifying routine preoperative diagnosis between private practice and the surgical university clinic]

In an attempt to shorten the preoperative in-patient period and to avoid unnecessary investigations, a cooperative patient management model was established for a number of surgical operations at the University Department of Surgery, Anaesthesiology and their referring Specialist and General Practitioners. The latter were requested to carry out the previously defined preoperative routine investigations, which allowed for a marked reduction in hospital diagnostics. Ambulatory preoperative patient management and a new admission routine resulted in a 57% decrease of the average preoperative in-patient stay for the observed procedures.
