Abstract: In order to advance the digitized process of a hospital, implement the digitization of diagnose flow in the hospital, the authors analyze the situation of information construction in the hospital. The authors design a workflow management system which is based on J2EE architecture and make full use of the advantage of it. The system, which adapts to the diagnose flow, is designed for the real situation in the hospital. It can decrease the former coupling of departments in the hospital and build the e-hospital on it by integrating all function modules of the business system. The authors can dynamically customize the diagnose flow and develop the flow rapidly by using the system. Seeing a doctor in the hospital becomes a standard, scientific, systemic process by using the workflow management system.
