Demographic trends in most European countries are forecasting a massive increase in the elderly population and a dramatic increase in emergency situations. Elderly people living alone are especially endangered as delays in alerting medical emergency services often leads to prolonged hospital stays resulting in an increasing number of elderly people being placed in nursing homes; at significant additional cost and an unnecessary deterioration in their quality of life. It has been recognised that daily activities are an important part of the functional health status and are often influenced by habits, age, culture, day of the week and the time of year. Activities like sleeping, going to the toilet, preparing meals and general mobility, which follow certain individual stereotypes have shown to be sensitive to changes in daily routines.
