Chartrounds.org is a virtual platform that aims to improve the quality of cancer care by connecting radiation oncologists worldwide with highly specialized, disease site-specific experts. Specifically, the Chartrounds web-based conferencing program offers radiation oncologists a scheduled one-hour case review session over the internet with a disease site-specific specialist and their peers. During a session, the radiation oncologists present their patient’s case and treatment plans. The expert-host reviews each of the submitted cases and offers practical expert advice. New data and approaches are frequently discussed. Over the past 10 years, Chartrounds has expanded to include specialists and members from around the world with platforms specifically dedicated to radiation oncology care in Africa, India, Latin America, and the US as well as a site focused specifically on the practice of brachytherapy.
