The demographic aging in Taiwan leads to growing needs in long-term care for the elderly, whereas the increase of demand is faster than that of the supply. The focal issue of the development of long-term care for the elderly is how to effectively allocate resources, thereby facilitating the elderly to receive the care they need in their domicile communities. This research proposes an automatic monitoring information system (AMIS). architecture to assist medical staffs to monitor the physiological functions of patients, such as chronic patients, alone elders, and distance patients.In this light,we can increase the survival rates of these patients. In this an Internet based AMIS, the infrastructure of. The analytical data of physiological equipments can be transmitted to the hospital central databases, immediately via mobile devices, GPRS or WAP.Consequently, AMIS can alert the medical related staffs the physiological situations of these patients if the patients? physiological functions are beyond normal ranges. These patients can then be treated in more appropriate and timely manner. The AMIS would strengthen the monitoring and aid chronic and emergent patients. And significantly increase their survival rates.
