“Patient engagement is a subset of participatory medicine. Participatory medicine is about partnership between the patient and the clinical or scientific expert,” explains “ePatient Dave” deBronkart. “The whole purpose, the context, for this entire initiative is not to have physicians feel threatened, but to help healthcare achieve its potential with the patient contributing what they're able to.” Author of Let Patients Help: A Patient Engagement Handbook, Dave is a cancer survivor, patient advocate, and activist working to revolutionize the relationship between patients and healthcare providers.
