Telehealth Application Domains
The Center for Connected Health Policy, the federally-designated National Telehealth Policy Resource
Center, describes four key telehealth
application domains: live video, store-and-forward, remote patient monitoring, and mobile health.
Live Video (Synchronous)
Live video is the most commonly used form of delivering
telehealth. Live video includes two types of technology:
Video device, typically a camera
Display device, such as a television, a tablet, a projector, or a computer screen
connection allows the provider to examine and observe the patient in real time, deliver psychiatric
evaluations, and consult with other providers, among many other benefits.
In store-and-forward systems, rural providers transmit secure health information to external specialists in
order to seek consultations outside of a real-time patient interaction. For example, a rural provider could send
a patient's X-ray images to a specialist through secure channels and receive a diagnosis through email. Some
store-and-forward systems are conducted entirely through electronic health records.
Remote Patient Monitoring (RPM)
Providers use RPM technologies to track and monitor patient data from a distance. For example, a program for
patients with hypertension might use an electronic blood pressure monitor to send daily readings to a database.
The provider can review the database to monitor progress and suggest treatments to maintain the patient's
health. By continually tracking patient data and offering preventive treatments, providers may be able to reduce
hospital readmissions and utilization of emergency services. Module 2: Increasing Access to and
Engagement with Care Outside of Healthcare Settings provides additional information about RPM in home
Mobile Health (mHealth)
mHealth typically refers to health education or tracking provided via mobile devices, including cell phones and
tablets. RPM interventions can involve mHealth as a means of communicating with patients. For example, patients
can use mobile apps to collect health data, such as vital signs.
