“Welcome to the RHIO Wiki: The Only Online, Real-time Forum on RHIOs and Health Information Exchanges: The Center for Health Transformation, eHealth Initiative, and CHIME have partnered to create the RHIO Wiki. This forum will educate community leaders who are working on RHIOs and health information exchanges about other efforts, experiences, and best practices from initiatives across the country. The RHIO Wiki is an open, online, real-time tool for community leaders to collaborate on health information exchanges by: 1) searching a library of information on other local and regional efforts; 2) asking and receiving from other leaders their thoughts on specific challenges, issues, and opportunities; and 3) sharing with other leaders their own experiences, expertise, and knowledge.”
