The heart of the Federal Digital Health Program, renamed as "Impulsa" as of last November, is the health information cloud or interoperability bus: this channel allows different databases of the public and private health system in Argentina - fragmented and highly diverse - communicate with each other. It gathers information from the Renaper, the provincial systems, the Sumar program, the Nomivac vaccines program, private effectors and Anses, among other actors. As explained by Fernando Núñez, National Director of Health Governance and Integration, it allows, through the implementation of interoperable resources, to transmit the summary of the Histora Clínica Electrónica, HCE (E-Medical Record), unequivocally identify the person, consult the health history, and prescribe prescriptions. And it will grow in services as new platforms are added -teleconsultation, for example- and public and private establishments.
