This document discusses patient-initiated information exchange and supporting patient-driven care coordination through technology. It describes several technologies for sharing health information, including Blue Button, iBlue Button, personal health records (PHRs), and patient portals. However, fully seamless sharing of health data has not been achieved due to technical, financial, cultural, and legal barriers. These include a lack of data standards, unclear data ownership, cost barriers, and a physician-directed rather than patient-centered model of care. The goal remains to empower patients to access and share their health information through digital tools.
