A process reengineering perspective suggests that public health emergency response requires a low degree of mediation and a high degree of collaboration. Employing a functional coupling framework, this paper analyzes China’s former public health processes and describes the ongoing development of the public health emergency information system (PHEIS) in China. Five problems of the former public health processes are identified, which have largely limited China’s ability to respond to public health emergencies efficiently and effectively. The structure and functions of PHEIS are described, and the facilitation of PHEIS as part of China’s public health process reengineering is explained. In addition, this paper discusses implications for future public health emergency information system development.
