There’s a movement underway in health care. Some would even call it a revolution. Patient engagement, doctor-patient communication, and shared decision-making are growing by leaps and bounds, driven largely by technology.

Now, the OpenNotes movement is ushering in a new era of transparency in medicine, to the benefit of doctors and patients alike.
