Abstract

Objective

Ubiquitous healthcare (u-Healthcare) is an emerging paradigm in the healthcare environment. One of the most promising applications for u-Healthcare is the ubiquitous home health monitoring system. This paper addresses two significant challenges in the successful application of the ubiquitous home health monitoring system: the uniform integration of measured biosignal data and easy access to monitored biosignal data.

Methods

We used the Medical waveform description Format Encoding Rule (MFER) standard to encode biosignal data. A web-based MFER upload ActiveX control was designed and implemented to transfer MFER files to the central repository server in a near real-time basis. All of the integrated biosignal data were then accessed and managed through the central repository server.

Results

We developed a u-House server that can serve as a uniform data transferer to integrate measured biosignal data from u-House homes into the remote central repository server. We developed user-friendly web services that allow users to easily search and view monitored biosignal data.

Conclusion

The results of this study suggest that the MFER standard can be easily adapted to u-Healthcare systems and that a web-based ubiquitous home health monitoring system has advantages of ubiquitous access and scalability.
