Assessment of patients' ability to review electronic health record information to identify potential errors: cross-sectional web-based survey.
Patient access to electronic health records (EHRs) can improve health outcomes but is not without concern. This survey of users of a patient portal providing online access to EHRs identified several barriers to understanding information contained in their electronic records, including medical terminology, interpretation of test results, and information display. These barriers signal potential avenues for improving systems providing patient access to their health records.
