Abstract

In recent years, the focus of health policy has been shifting from reactive and acute healthcare in hospital towards providing more proactive and preventive healthcare. Because emergency admission to hospital and continuous check up at hospital are extremely costly, and do challenge the available medical resources, the mode of healthcare is being innovated to reduce and avoid this circumstances. In fact the reason for staying in hospital in most cases is not because a patient actually needs continuous observation for reliably detecting the progressive abnormalities, timely monitoring therapy effect or avoiding occurrence of adverse events in recovery process of post surgery. Meanwhile, early detection of health anomalies can greatly reduce the emergency admissions to large acute centers. Therefore, medical and health societies are seeking the technologies to be able to advance healthcare by early detection of health anomalies and by early discharge of patients from hospital with continuous observation. This will not only reduce the risk of cross-infection, but also significantly decrease the cost of hospitals
