[Security and user acceptance of an intelligent home emergency call system for older people living at home with limited daily living skills and receiving home care]. / Sicherheit und Nutzerakzeptanz eines intelligenten Hausnotrufsystems im Einsatz bei älteren pflegebedürftigen zu Hause lebenden Menschen mit eingeschränkter Alltagskompetenz.

BACKGROUND: Technically based support measures are becoming increasingly more important in an aging society. Such support measures can provide a self-determined life in familiar surroundings despite the need for care. An example for such a support measure is an intelligent home emergency call system (iHNR system), which automatically detects critical situations (e.g. falling down), transmits this information to an emergency call center and therefore initiates assistance faster. OBJECTIVE: The aim of this uncontrolled, two center observational study was to evaluate the security and acceptance of an iHNR system used by older people receiving home care. MATERIAL AND METHODS: The study was carried out based on 51 subjects with at least a 6-month observation period using the iHNR system. The iHNR system was installed in all homes of the participants. Interviews about acceptance, perceived and objective security, impact on independence and usability of the new iHNR system were conducted. Analysis was performed with particular respect to depression, quality of life, frailty and self-estimated need for assistance. RESULTS: A total of 39 complete records were collected and evaluated. The participants represented a vulnerable group of people with rather depressive moods, negative quality of life and a high level of frailty without significant changes over the observation period. Positive results were found regarding subjective and objective security and acceptance as well as ease of operation of the iHNR system. The fear of falling was only marginally influenced. CONCLUSION: Acceptance regarding the new iHNR system was high. The system provoked a stronger sense of security while at the same time leading to a reduced sense of control. The system seems to be able to detect critical events and can automatically and quickly alert the necessary help services. Therefore, people in need of care can remain longer in their own homes.

Development of a personal health monitoring system--the IT-systems industry view.

The Development and Implementation of PHM systems require a different approach than typical application development processes. Based on a practical example it is described how ethical and legal aspects will be considered during the development process. The result is a cohesion and adoption of different methods with defined interaction points to reiterate the solution design by legal and ethical aspects.
