Elderly-care is an important issue in an aging city like Hong Kong. HKSAR has strict rules and regulations imposing on elderly-care institutions. However, that rules and regulations rely on signatures, checks and cross-checks makes elderly-care a boring profession. Huge amount of documents must be stored and retrieved during visits by SWD. That carers have to spend much more time on administration than caring would discourage people who devote to serve elderly rather than paper works. Cloud technology in elderly-care designed with electronic signatures, touch screen reporting, paperless vital sign measurements provides a cool way to attract devoted young people entering the profession, to discourage cheatings and abuses, to provide real time data for improving quality and to eliminate medication incidences. Technology can also help to reduce drug wastage and drug interaction problems as medicines may come from various sources avoiding re-hospitalization. According to WHO, there is a strong correlation between environment and disease. Smart Integration Company devotes to connect technologies in healthcare and environment to promote a healthy society for Hong Kong people, in particular, elderly.
