Background and Objectives: There are a few problems restraining the effective operation of telemedicine in China. On the basis of practices of the Henan Province Telemedicine Center of China (HTCC), the purpose of this study was to design a telemedicine system jointly driven by videoconferencing and data exchange to address the issues limiting the further development and implementation of telemedicine. Methods: Based on service-oriented architecture, the organizational design of the telemedicine system was gradually refined from top to bottom to complete its hierarchical layout. Technologies including multiprotocol stack adaptation, self-adaptive multilink network transmission, information exchange of heterogeneous medical systems, and open application system architecture were also used to construct the system. Results: The telemedicine system realizes the integration of videoconferencing, data acquisition and exchange of heterogeneous medical information systems, and the actual applications and expansion of telemedicine services. The HTCC currently covers more than 500 telemedicine centers, workstations, and service points, forming a five-level "province-city-county-township-village" telemedicine network linkage. The HTCC handles nearly 30,000 teleconsultation cases per year, helping patients save about ¥120 million Chinese Yuan RMB (approximately US $17.5 million). Conclusions: The proposed telemedicine system achieves satisfactory operation effects, along with social and economic benefits. It has the potential to increase the coverage of medical resources in remote regions, and it can play a role in solving other problems facing telemedicine development in China. The findings also inform measures for further improvement in telemedicine's implementation effects, service quality, and application scope in China and globally.
