APPROACH u Not to create new standards but leverage off of existing standards. u Create “profiles” of existing standards to be used for Telehealth. u Where needed and only where needed create “new elements” in relation to existing standard(s). u Use proper procedures to move these “new elements to become a part of the standard(s).
