This document discusses the concept of participatory medicine and the role of patients in their own care. It makes three key points: 1) Meaningful use standards for electronic health records must include patient access to medical records and data. 2) Foundational principles of participatory medicine include that the patient is not a third party and has the right to access and share their own medical data and pursue different treatment options. 3) When patients are empowered and engaged through access to health information and online communities, they can help advance medicine by sharing their experiences, findings new treatment approaches, and identifying gaps in research.
