Disease management is a program which attempts to overcome the fragmentation of healthcare system and improve the quality of care. Many studies have proven the effectiveness of disease management. However, the case managers were spending the majority of time in documentation, coordinating the members of the care team. They need a tool to support them with daily practice and optimizing the inefficient workflow. Several discussions have indicated that information technology plays an important role in the era of disease management. Whereas applications have been developed, it is inefficient to develop information system for each disease management program individually. The aim of this research is to support the work of disease management, reform the inefficient workflow, and propose an architecture model that enhance on the reusability and time saving of information system development. The proposed architecture model had been successfully implemented into two disease management information system, and the result was evaluated through reusability analysis, time consumed analysis, pre- and post-implement workflow analysis, and user questionnaire survey. The reusability of the proposed model was high, less than half of the time was consumed, and the workflow had been improved. The overall user aspect is positive. The supportiveness during daily workflow is high. The system empowers the case managers with better information and leads to better decision making.

The telehealth care system has been important in the healthcare world for several decades; however, Taiwan only began work on telehealth care this past year. This paper outlines the effectiveness of the telehealth care system developed by the National Taiwan University Hospital (NTUH). The usability of the integrated telehealth care system was analyzed through of heuristic evaluation and its usefulness. By using the heuristic evaluation form as developed by Nielsen, it is possible to examine the telehealth care system from the user's perspective. In addition, in assessing the usefulness through lists of criteria, system developers can determine the pros and the cons of the database. Ultimately, the heuristic evaluation revealed several violations on the system, but are not prohibitive to the development of such as system. Similarly, evaluation of the usefulness comes out positive; despite the fact that the suggested changes proposed by the users can be said are the main weaknesses of the system. With some improvements, the telehealth care system can be used efficiently in NTUH's healthcare system.
