Abstract
We established the Global Collaboration Medical Network System Committee (GCM) in 2008, and since that time we have been involved in the development of a medical community system together with a medical association in the eastern part of Shizuoka prefecture. A large amount of research on the development of medical community systems has been conducted, and many approaches have been attempted in the past. However, since many such projects do not involve widespread collaboration and are based on client/server and web systems, various problems such as large initial investments and high running costs have hindered the popularization of global medical collaboration network systems. In addition, medical data and registration information for the nationwide resident registry network in Japan were lost due to the Great East Japan Earthquake, emphasizing the importance of preserving medical data in the event of natural disasters. To address the above problems, GCM has developed a cloud-based medical community system. We present a positive prototype system for a global collaboration medical system. The effectiveness of this system is demonstrated by the Lung Cancer Screening System.
