The Stanford Cancer Institute is undergoing a 5-year Transformation Initiative that began in 2013. One of the goals of this initiative is to increase patient engagement. The underlying premise is that engaged patients will be more likely to attend all their visits, receive all their treatments, and understand ways to manage treatment side effects so that they are less likely to go to the emergency room (ER) or be admitted to the hospital. An approach being tested is to use lay navigators to help identify patient issues and then help them address the issues through a combination of direct supportive activities (e.g., calling clinical team for the patient) and activities that help the patients help themselves (helping them understand when side effects warrant a call to their clinical team that they make themselves).
