Ample evidence indicates that improved patient engagement is better for doctors and patients. With EHRs and government regulations, the rise of patient portals has been dramatic. A recent AMA study says that 92% of hospitals offer the ability to view medical records through an online portal (compared to 43% in 2013). But availability of an online portal doesn’t mean patients are accessing or getting value from it. How can we help patients move from simply looking up lab results, requesting refills, and checking schedules to more active and meaningful engagement? One technically simple, but remarkably powerful answer is to have clinicians share their visit notes with patients. It’s something we call OpenNotes.
