More than 4 decades have passed since the call for “giving patients their medical records” was first proposed to increase patient engagement in health care delivery.1 Today, this vision—once considered radical—is quickly becoming reality, with millions of Americans routinely accessing their medical records through web-based patient portals.1
The electronic health record content that patients can access online is expanding to include physicians’ documentation of patient visits. Recent studies evaluating OpenNotes, a patient-centered initiative enabling online access to providers’ clinical notes, have demonstrated high levels of patient utilization and improved self-reported understanding of care planning and medication adherence, resulting in patients “feeling more in control of their health care.”1
