Use of Standards: Aided MyHealtheVet
with the use of standards to benefit the 7
million Veteran patients that use it. First, with use of health
information exchange interface to the nationwide health exchange, and
enabling the Veteran to Consent or Dissent using FHIR Consent resource.
Second, empowering the Veteran to report their own measurements for
