The technical development of the so-called "AAL Wizard" is basis for the study. The AAL-Wizard is an IHE(Integrating the Healthcare Enterprise)-compliant, web based documentation and communication platform with an integrated electronic patient record, which can be used by the study participants during the study. Vital parameters are collected with the help of certified medical products according to the guidelines "93/42/EEC(European Economic Community) on medical devices" (e.g. blood pressure devices, scales, pedometers), transmitted electronically, documented and archived directly in the system. Vital parameters out of range will be prioritized displayed in the AAL Wizard (e.g. traffic light system, short message notification, pop-up function, etc.) and the study participant will be contacted by the tele doctor (teleconsultation) . The decision on the necessary intervention (e.g. contact of the in-house home care, therapeutic and diagnostic recommendations or recommendation of a primary care consultation /hospital submission) are in the responsibility of the tele doctor based on the communication with the patient and the family doctor`s recommendations for the treatment of his patient.
