Rate of elderly people in the developed countries is larger and larger and not enough younger people exist to take care of them. To provide sustainable elderly care, we propose health care monitoring system, based on data mining approach. The aim of this study is to provide health monitoring system to allow quality and safe living of elderly at homes instead of needing them to go to nursing homes, which are also overcrowded. Moreover, their offspring would not be overwhelmed with care for the elderly. Therefore, the aim of this research is to provide sustainable elderly care. The study proposes a general and specific approach, both achieving classification accuracies over 97%.
