Synchronous, real-time or Clinical Video Telehealth requires the presence of both parties at the same time and a communication link between them that allows a real-time interaction to take place. Video-conferencing equipment is one of the most common forms of technologies used in synchronous telehealth. There are also peripheral devices that can be attached to computers or the video-conferencing equipment which can aid in an interactive examination.

Nursing Call Center – This is a centralized office where nurses are the ones who are working. The nurses are responsible for answering telephone calls from patients. They should also make responses to faxes, electronic mails and letters from patients. Nursing call centers may also provide the callers with the basic information regarding their health, but they should not disclose the diagnosis made by the doctors on their conditions. They should not prescribe medications as well. They may just provide basic instructions when patients are having health complaints.


“Telemedicine is the natural evolution of healthcare in the digital world,” American Telemedicine Association. Telemedicine empowers the caregivers to remotely interact with their patients, which greatly improves both the efficiency and affordability of healthcare. Today patients, doctors and caregivers have learned to accept telemedicine (often called ‘telehealth’ or ‘connected health’) as one of many ways of delivering care.
Each online video chat appointment with a doctor costs patients $40; doctors get $30 of that, with the company taking a $10 cut. Doctors can diagnose illnesses and prescribe medication, but the app and website are not recommended for any patient experiencing a potentially life-threatening emergency medical condition. Doctors also cannot use it to prescribe medications like sedatives and narcotics.

More widespread use and success of telehealth applications might spur the resolution of these reimbursement issues. CVS has been providing clinical services via telehealth since 2015. According to their study in the Journal of General Internal Medicine, 95 percent of patients “were highly satisfied with the quality of care they received, the ease with which telehealth technology was integrated into the visit, and the timeliness and convenience of their care.” If CVS’s merger with Aetna is finalized, increased competition may motivate other payers to find ways to offer telehealth services and, by extension, levels of reimbursement. 
Today the telemedicine field is changing faster than ever before. As technology advances at exponential levels, so does the widespread affordability and accessibility to basic telemedicine tools. For example, not only do we now have the technology for live video telemedicine, but much of the U.S. population has experience using online videochat apps (like Skype or Facetime), and access to a computer or mobile device to use them.

Due to its digital nature it is often assumed that telehealth saves the health system money. However, the evidence to support this is varied. When conducting economic evaluations of telehealth services, the individuals evaulating them need to be aware of potential outcomes and extraclinical benefits of the telehealth service.[37] Economic viability relies on the funding model within the country being examined (public vs private), the consumers willingness-to-pay, and the expected remuneration by the clinicians or commercial entities providing the services (examples of research on these topics from teledermoscopy in Australia [38][39][40]).
In-person patient-doctor visits are clearly valuable and necessary in many circumstances. Telemedicine is best used to supplement these visits – to do simple check-ins with patients and make sure everything is going well. For minor acute conditions (like infections), an in-person visit with an established patient is often not needed. In those cases, telemedicine can save the patient, the doctor, and the healthcare system time and money.
The future appears to be bright for virtual healthcare services. Patients like using the services because of the convenience. Payers like virtual healthcare because it lowers their costs. As overall healthcare costs increase with more older individuals across the world, telehealth should experience even more growth as a way to control costs without angering patients. 
RPM telemedicine is quickly rising in popularity as more health professionals realize its potential effects on chronic care management. For instance, a patient with diabetes who has a glucose tracker in their home can measure their glucose levels at regular intervals and transmit them to their doctor. If all is well, those results are simply recorded. If something looks off, the physician may flag it and call in the patient for a consult.
34 states and the District of Columbia require that private insurers cover telehealth the same as they cover in-person services. Many other insurers cover at least some telehealth service--and many more have expressed interest in expanding their telehealth coverage. To find out if your insurance company covers telehealth services, please contact your benefits manager. 
Teleradiology : This is the transfer of radiological images. X-Rays, MRIs and CTs are all types of radiological images. These images are used for consultation, diagnosis or interpretation. They can be transferred through satellite connections, local area networks or even standard telephone lines. The Picture Archiving and Communications Systems allow centralized storage and the access of these images over information systems such as computers.

ECGs, or electrocardiographs, can be transmitted using telephone and wireless. Willem Einthoven, the inventor of the ECG, actually did tests with transmission of ECG via telephone lines. This was because the hospital did not allow him to move patients outside the hospital to his laboratory for testing of his new device. In 1906 Einthoven came up with a way to transmit the data from the hospital directly to his lab.[46] See above reference-General health care delivery.

“Formally defined, telemedicine is the use of medical information exchanged from one site to another via electronic communications to improve a patient’s clinical health status,” the ATA writes. “Telemedicine includes a growing variety of applications and services using two-way video, e-mail, smart phones, wireless tools and other forms of telecommunications technology.”


“Creating a viable telemedicine program is both a short-term and a long-term proposition,” said Daniel Barchi, CIO at New York-Presbyterian. “It is possible, with a small team and early investment of resources, to create telemedicine capability in a specific vertical. It could be post-surgical follow-up visits for patients and surgeons, medication reconciliation video visits with a pharmacist, or urgent care emergency department video calls.”

Like most technology solutions, telemedicine platforms usually require some training and equipment purchases. How much is really dependent on the solution – a more extensive inpatient telemedicine platform that will be used between primary doctors and consulting specialist may require more training and the purchase of a telemedicine cart and various mobile health devices. A secure videochat app like eVisit, requires much less staff training and usually only requires purchase of a webcam.
While laws about prescriptions issued via telemedicine consultations are stringent in many states, the general trend indicates more states will allow these types of online prescriptions, the Center for Connected Health Policy reported. A sticking point is that prescriptions require the establishment of a doctor-patient relationship, and some states do not qualify virtual visits as a legitimate relationship.
Telemedicine can be beneficial to patients in isolated communities and remote regions, who can receive care from doctors or specialists far away without the patient having to travel to visit them.[4] Recent developments in mobile collaboration technology can allow healthcare professionals in multiple locations to share information and discuss patient issues as if they were in the same place.[5] Remote patient monitoring through mobile technology can reduce the need for outpatient visits and enable remote prescription verification and drug administration oversight, potentially significantly reducing the overall cost of medical care.[6] Telemedicine can also facilitate medical education by allowing workers to observe experts in their fields and share best practices more easily.[7]
Reimbursement for Medicaid covered services, including those with telemedicine applications, must satisfy federal requirements of efficiency, economy and quality of care. States are encouraged to use the flexibility inherent in federal law to create innovative payment methodologies for services that incorporate telemedicine technology. For example, states may reimburse the physician or other licensed practitioner at the distant site and reimburse a facility fee to the originating site. States can also reimburse any additional costs such as technical support, transmission charges, and equipment. These add-on costs can be incorporated into the fee-for-service rates or separately reimbursed as an administrative cost by the state. If they are separately billed and reimbursed, the costs must be linked to a covered Medicaid service.
Telemedicine is an important and quickly growing component of healthcare delievery in the United States.  There are currently about 200 telemedicine networks, with 3,500 service sites in the US.  In 2011 alone the Veterans Health Administration delivered over 300,000 remote consultations using telemedicine. More than half of all U.S. hospitals now use some form of telemedicine.
When a patient is in the hospital and he is placed under general observation after a surgery or other medical procedure, the hospital is usually losing a valuable bed and the patient would rather not be there as well. Home health allows the remote observation and care of a patient. Home health equipment consists of vital signs capture, video conferencing capabilities, and patient stats can be reviewed and alarms can be set from the hospital nurse’s station, depending on the specific home health device.

Today, most people have access to basic telemedicine devices like mobile phones and computers. With improved accessibility, individuals in rural areas and busy urban areas can connect with a provider with ease. Home-use medical devices make it possible for caregivers to monitor everything from vitals to glucose levels. Physicians can gather essential medical information and make a diagnosis without patients stepping foot in a doctors office.

Wyoming Medicaid conducted a study measuring engagement and post-birth outcomes for patients  who used a mobile health app called, “Due Date Plus.” Use of the app, which allowed women to record pregnancy milestones, access medical services, and find symptom-related information was associated with increased compliance with prenatal care and decreased occurrence of babies born with low birth weights.

Type of telehealth. Medicare primarily only reimburses for live telemedicine, where the physician and patient are interacting in real-time through secure, videochat. This type of telemedicine visit is meant to substitute a face-to-face in-person visit. The only exception is in Hawaii and Alaska, where Medicare reimburses for store-and-forward telemedicine as well.

RPM telemedicine is quickly rising in popularity as more health professionals realize its potential effects on chronic care management.

If all is well, those results are simply recorded. If something looks off, the physician may flag it and call in the patient for a consult.


Telehealth can also increase health promotion efforts. These efforts can now be more personalised to the target population and professionals can extend their help into homes or private and safe environments in which patients of individuals can practice, ask and gain health information.[8][21][24] Health promotion using telehealth has become increasingly popular in underdeveloped countries where there are very poor physical resources available. There has been a particular push toward mHealth applications as many areas, even underdeveloped ones have mobile phone coverage.[25][26]

In its mHealth Roadmap, the Health Information and Management Systems Society (HIMSS) muddies the waters a bit. It uses the Health and Human Services Definition for telehealth — “the use of electronic information and telecommunications technologies to support remote clinical healthcare, patient and professional health-related education, public health and health administration” — then goes on to say that “telemedicine usage ranges from synchronous video chat between a patient and a doctor, to conferencing between doctors, to conferencing between doctors and allied health professionals (e.g., nutritionists, physical therapists), to providing live or recorded presentations to groups of patients who are geographically separated.”
Medical City Virtual Care allows patients to see and talk to licensed, board-certified physicians, nurse practitioners or physician assistants from their mobile device or computer through a secure internet video connection. These healthcare professionals can diagnose, treat and prescribe non-narcotic medication for a wide variety of adult and pediatric non-emergency medical conditions, including:
