Healthcare Information Management System in Home Environment

The distributed object group framework (DOGF) enables easier integration of distributed objects to healthcare home applications. This paper describes a healthcare information management system for supporting healthcare home services based on DOGF. The system architecture consists of healthcare database management tool, framework, sensor manager and physical elements such as sensors, devices and appliances. The focus of this paper is on the design and construction of a database system in a framework to support home healthcare services. Healthcare information is organized using database schemes based on the specific types of data collected from various typedsensors. The database constructed from this information for the purpose of home healthcare services is divided into the base information that uses the real schemes and the context based information that uses the view schemes. To verify the practical use of the healthcare information management system proposed in this paper, we created a prototype healthcare home monitoring service using information, emergency call, and home appliance control. The result of the experimental evaluation shows the comparison of the execution service time of the base information and the context based information in our simulated scenario of a home healthcare application.
