Since its launch in June 2014, more than 600 facilities across the country have joined RO-ILS: Radiation Oncology Incident Learning System® to contribute patient safety data to a national database. The mission of RO-ILS is to facilitate safer and higher quality care in radiation oncology by providing a mechanism for shared learning in a secure and non-punitive environment. Participation in RO-ILS is free thanks to the generous financial support of ASTRO, AAPM, Varian, ASRT, AAMD and Sun Nuclear Corporation. RO-ILS provides U.S.-based practices access to a secure, web-based portal and the ability to send data to a federally listed Patient Safety Organization (PSO). To learn more, watch an Introduction to RO-ILS video and contact RO-ILS staff.
