[Web based audiovisual patient information system--a pilot study of the preoperative patient information].

A considerable part of the medical clinical daily routine incorporates the information of patients about medical diagnosis and especially about the scheduled operative intervention. The disease pattern, the course in the hospital before and after surgery and the operation itself will be discussed during these conversations. The patient has to be informed about all potential complications from a medico legal point of view. To optimise information delivery, auxiliary materials like charts, pictures, X-rays and models are used. Unfortunately, only a small percentage of the presented information is assimilated by the patient after strict verbal information. To inform patients better and earlier about medical details and internal processes before the operation, we developed a web-based audiovisual patient information system with a combination of pictures, text, tone and video about surgical interventions. The patient satisfaction could be markedly improved by the application of this patient information system in the informed consent process. Furthermore, the use of the web-based multimedia information portal may leads to an essential time saving for the medical staff.
