A Web-based mobile asthma management system

Continuous recording of daily symptoms constitutes an effective means of managing asthma patients. Daily management reduces the costs associated with hospitalization and improves the quality of patient care. We have implemented a Web-based mobile asthma management system. We used a pocket PC, mobile phone and desktop computer. The recorded items and individualized prescriptions were structured using Extensible Markup Language (XML) DTD (Data Type Definition). The mobile Web form was automatically adjusted to fit the different display resolutions of the terminal devices. The system provided reliable exchange of all relevant information between a doctor and the asthma patient using wireless mobile transmission. Email and Short Messaging Service (SMS) were used to send messages to patients, for example in the case of an automatically determined patient alert. Patients could obtain customized instructions according to their daily personal symptoms, peak expiratory flow (PEF), medications and activity restriction. The daily graph of PEF and the graphs of symptoms and medication were particularly useful for asthma patient control and self-awareness of the progress of the disease.
