The purpose of this project is to implement "Homecare Nursing Network System" using wireless network which was able to manage homecare service efficiently. Therefore, by completing the project of "Homecare Nursing Network System", the research team connected the headquarter and the local homecare service offices over the Internet, and built the database and application programs to operate the offices. Homecare nurses are using the PDA(personal digital assistant) in order to provide homecare nursing service, to record the patients' data, and to send and receive the data in real time. It results in improving the quality of the homecare service through the computerized knowledge-based assess and intervention algorithms. The team also has implemented the homepage to introduce the homecare office and to provide the homecare service information. "Homecare Nursing Network System" allows us to manage homecare nursing service under the computerized environment, to keep track of the homecare nursing document efficiently, to improve the quality of homecare nursing, and to expand its business territory.
