AB 133 makes into law the need to have bidirectionality in healthcare records: patients can access their records and the treating MD can access the patient's record from the other treating MDs. This AB 133 grew out of TEFCA: Trusted Exchange Framework and Common Agreement as part of the federal suggested guidelines. TEFCA establishes a universal floor of interoperability, connecting public health entities and patients. The development of TEFCA was mandated by the 21st Century CURES Act on January 19, 2022: US HHS office of the National Coordinator for Helath Information Technology (ONC) published the TEFCA.
