Social media and online tools are empowering patients and enabling new forms of participatory healthcare known as Health 2.0. Patients are increasingly educated online and use social platforms like Facebook, Twitter, blogs and YouTube to find health information and connect with providers. While this presents challenges around privacy and professional standards, it also offers opportunities if used strategically. Social media could help disseminate public health updates, answer general questions, send reminders, and help patients access resources and care. Early evidence suggests some providers are seeing new patients and income from their online presence.
