Scaling-up a telemedicine service involves careful preparation and planning for managing change. Telemedicine “doers” worked together actively in Momentum, a co-financed European Commission project, on how to manage changes to telemedicine services. In 2015, they came up with 18 critical success factors that are best used to deploy a telemedicine service, looking specifically at the importance of change management. Translated into a workshop and accompanying survey, now called the Momentum process, the European Health Telematics Association (EHTEL) offers training in these success factors. The factors have already been used by several sites in Europe to move telemedicine services forward in a practical way. This workshop, can help telemedicine practioners, in Europe and globally, make progress on the expansion of this useful technology.
