Intelligent Personal Health Record

Web-based personal health records (PHRs) are widely available to ordinary consumers at present, but the existing PHR systems have limited intelligence and can fulfill only a small portion of users’ healthcare needs. Previously, we proposed the concept of intelligent PHR (iPHR) to improve PHR’s capability and usability. By introducing and extending expert system technology, Web search technology, natural language generation technology, database trigger technology, and signal processing technology into the PHR domain, iPHR can automatically provide users with personalized healthcare information to facilitate their activities of daily living. This chapter presents an overview of our iPHR system that currently provides four functions: guided search for disease information, recommendation of self-care activities, recommendation of home health products, and continuous user monitoring.
