The need for an improved understanding of the rehabilitation services landscape in Ontario and for promotion of Cancer Care Ontario’s newly developed Exercise for People with Cancer guideline brought Cancer Care Ontario’s Psychosocial Oncology and Survivorship Programs together to host a knowledge translation and exchange event. The primary objectives of the event were to understand recommendations from Cancer Care Ontario’s new exercise guideline, to discuss key considerations and determine strategies for the implementation of the guideline recommendations, and to explore the current state and future directions of cancer rehabilitation in Ontario. The event was attended by 124 stakeholders, including clinicians, allied health care professionals, administrators, patients, community partners, and academics representing each of the 13 regional cancer programs in Ontario. Attendees participated in two small-group activities that focused on determining the best approach for implementing the guideline recommendations into practice and discussing current barriers and the future state of cancer rehabilitation in Ontario. The activities allowed for networking and collaboration between attendees. The event provided an opportunity for the Psychosocial Oncology and Survivorship Programs to learn about the types of goals and plans that could be feasible in implementing the guideline in each region, and about ways to prioritize gaps in access to rehabilitation services and the types of implementation strategies that might be used to address the gaps. Overall, attendees were highly satisfied with the event, and the findings are being used to help inform research and practice activities with respect to guideline implementation and rehabilitation practice.
