Data-driven healthcare improves patient safety, reduces waste. Stanford uses total patient data to avoid negative drug interactions, costly repeat tests. Interoperability between health IT systems aids understanding of care history. HHS's TEFCA enables universal interoperability using private-public partnership, collaborative approach. Lack of single connection point impedes patient data sharing, reduces healthcare quality. TEFCA's network-interconnectivity eliminates need for multiple legal agreements, connection points. Stanford, an early TEFCA adopter, envisions comprehensive patient care. Participation in TEFCA marks easy nationwide interoperability.
