Teleradiology – Teleradiology is actually one of the earliest fields of telemedicine, beginning in the 1960s. Teleradiology solutions were developed to expand access to diagnosticians of x-rays. Smaller hospitals around the U.S. may not always have a radiologist on staff, or may not have access to one around the clock. That means patients coming into the ER, especially during off-hours, will have to wait for diagnosis. Teleradiology solutions now offer providers at one location to send a patient’s x-rays and records securely to a qualified radiologist at another location, and get a quick consult on the patient’s condition.
While widespread research on the effects of telemedicine is still relatively young, many studies do show positive results. When the Veterans Health Administration implemented telemedicine for past heart attack patients, they sawhospital readmissions due to heart failure drop by 51%. Another study on the Geisinger Health Plan showed that telemedicine reduced 30-day hospital readmissions by as much as 44%. And while telemedicine skeptics often claim virtual visits tend to be lower quality than in-person visits, a recent study of 8,000 patients who used telemedicine recorded no difference in care outcomes between in-person and virtual care.
But it wasn’t until the early 20th century that the general population started to these technologies, and imagine they could be applied to the field of medicine. In 1925, a cover illustration of the Science and Invention magazine featured an odd invention by Dr. Hugo Gernsback, called the “teledactyl.” The imagined tool would use spindly robot fingers and radio technology to examine a patient from afar, and show the doctor a video feed of the patient. While this invention never got past the concept stage, it predicted the popular telemedicine definition we think of today – a remote video consult between doctor and patient.

Telemedicine for trauma education: some trauma centers are delivering trauma education lectures to hospitals and health care providers worldwide using video conferencing technology. Each lecture provides fundamental principles, firsthand knowledge and evidenced-based methods for critical analysis of established clinical practice standards, and comparisons to newer advanced alternatives. The various sites collaborate and share their perspective based on location, available staff, and available resources.[43]
Telemedicine has come a long way and there’s still so much room for growth. Currently, telemedicine is used to conference specialists on important appointments when patients have no other access, to provide diagnosis and prescriptions to remote areas where access to a physician isn’t always possible, and even to assist in invasive surgeries when a high caliber surgeon can’t reach a patient in time.
Like all technology in the healthcare space, telemedicine solutions need to be HIPAA compliant to protect patient privacy. While an app like Skype might offer a doctor an easy way to consult a patient remotely, using it in that way is not in compliance with HIPAA. Technology used for telemedicine services needs to ensure high-level security and prevent any breaches of patient personal health data.  
When the American National Aeronautics and Space Administration (NASA), began plans to send astronauts into space, the need for Telemedicine became clear. In order to monitor their astronauts in space, telemedicine capabilities were built into the spacecraft as well as the first spacesuits.[5][8] Additionally, during this period, telehealth and Telemedicine were promoted in different countries especially the United States and Canada.[5]
An example of these limitations include the current American reimbursement infrastructure, where Medicare will reimburse for telehealth services only when a patient is living in an area where specialists are in shortage, or in particular rural counties. The area is defined by whether it is a medical facility as opposed to a patient's' home. The site that the practitioner is in, however, is unrestricted. Medicare will only reimburse live video (synchronous) type services, not store-and-forward, mhealth or remote patient monitoring (if it does not involve live-video). Some insurers currently will reimburse telehealth, but not all yet. So providers and patients must go to the extra effort of finding the correct insurers before continuing. Again in America, states generally tend to require that clinicians are licensed to practice in the surgery' state, therefore they can only provide their service if licensed in an area that they do not live in themselves.[1]
In many states, current regulations require that any provider and patient doing a telemedicine visit have a pre-existing relationship. Usually this means that the provider and patient need to have had at least one in-person visit. This regulation is slowly changing as more companies like Teladoc and DoctoronDemand seek to connect patients with a random, on-call doctor for immediate care.
Used when both health providers are not available or not required at the same time. The provider’s voice or text dictation on the patient’s history, current affliction including pictures and/or video, radiology images, etc., are attached for diagnosis. This record is either emailed or placed on a server for the specialist’s access. The specialist then follows up with his diagnosis and treatment plan.
A landmark 2010 report by the World Health Organization found that telemedicine – literally meaning “healing from a distance” — can be traced back to the mid-1800s, was first featured in published accounts early on in the 20th Century, and adopted its modern form in the late 1960s and early 1970s, primarily through the military and space industries. Owing to the fact that much of the technology encompassed in today’s telemedicine platform wasn’t around back then, and noting a 2007 study that found 104 different peer-reviewed definitions for the word, the WHO settled on its own broad-based definition:
A question popular among organizations that want to implement telemedicine solutions is regarding how their physicians will be reimbursed. With telehealth regulations varying for each state and with payers setting up different policies, it is difficult to find consistency. What does remain consistent is that telemedicine is advancing and its becoming difficult for the key players to keep up.
For developing countries, telemedicine and eHealth can be the only means of healthcare provision in remote areas. For example, the difficult financial situation in many African states and lack of trained health professionals has meant that the majority of the people in sub-Saharan Africa are badly disadvantaged in medical care, and in remote areas with low population density, direct healthcare provision is often very poor[90] However, provision of telemedicine and eHealth from urban centres or from other countries is hampered by the lack of communications infrastructure, with no landline phone or broadband internet connection, little or no mobile connectivity, and often not even a reliable electricity supply.[91]
Sometimes called asynchronous telemedicine, store-and-forward solutions enable healthcare providers to forward and share patient medical data (lab results, images, videos, records) with a provider at a different location. These platforms offer a kind of sophisticated, secure, email platform – a way to share private patient data online in a secure way.
Likely a favorite among patients aging in place, telemedicine permits providers to monitor their patients in their own homes. Using patient portals, a physician can gather and share information with their patient. In addition, medical devices can send vital signs and more to providers so they can make adjustments to care as needed. VSee offers their clients the following telemedicine solutions:
The range and use of telehealth services have expanded over the past decades, along with the role of technology in improving and coordinating care. Traditional models of telehealth involve care delivered to a patient at an originating (or spoke) site from a specialist working at a distant (or hub) site. A telehealth network consists of a series of originating sites receiving services from a collaborating distant site.

Interoperability: This refers to two systems ((software, networks, communication devices, computers and other types of information technology components))or more being able to interact with each other and exchange information so that predictable results can be achieved. There are three different kinds of interoperability: technical; clinical and human/operational.
According to this 2015 Cardiac Implantable Electronic Device (CIED) study, patients whose implantation included remote monitoring capabilities had a higher rate of survival than patients without it. “ Furthermore, according to the Center for Technology and Aging, patients who participated in RPM were less likely to experience hospital stays, incurred fewer ED and urgent-care visits, and reported better management of their symptoms. They also indicated increased physical stamina as well as greater overall patient satisfaction and emotional well-being.
Telehealth requires a strong, reliable broadband connection. The broadband signal transmission infrastructure includes wires, cables, microwaves and optic fibre, which must be maintained for the provision of telehealth services. The better the connection (bandwidth quality), the more data can be sent and received. Historically this has priced providers or patients out of the service, but as the infrastructure improves and becomes more accessible, telehealth usage can grow.[1][2]
Fundamentally, we tend to think of telemedicine as a way to overcome a serious distance barrier between a patient and a healthcare provider. This point-to-point connection supports a critical function. There are cases when a patient requires the care of a particular doctor at a particular time, and technology is the best way to facilitate that interaction.
The amount providers are reimbursed for telemedicine will vary depending on a state’s legislation. Some states specifically mandate that private payers reimburse the same amount for telemedicine as if the service was provided in-person. However, most states with reimbursement mandates leave this determination up to the payers. We have found the majority of private payers still reimburse at levels equivalent to in-person visits.
Originally, health professionals developed this technology to reach remote patients living in the rural areas. But with time, medical staff and the U.S. government saw the big picture – the potential to reach urban populations with healthcare shortages, and to respond to medical emergencies by sharing medical consults and patient health records without delay. In the 1960s, heavy investments from the U.S. Government, including the Public Health Department, NASA, Department of Defense, and the Health and Human Sciences Department drove research and innovation in telemedicine. Sending cardiac rhythms during emergencies started at about this time. For instance, in Miami, the university medical center worked together with the fire rescue department by sending electro-cardiac rhythm signals over the voice radio channels from the rescue sites.
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.
Store-and-forward telemedicine is a great way to increase healthcare efficiency since a provider, patient, and specialist don’t need to be in the same place, at the same time. It also facilitates faster diagnosis, especially for patients located in underserved settings that may not have the necessary specialist on staff. Overall, this adds up to lower patient wait times, more accessible healthcare, better patient outcomes, and a more optimized schedule for physicians.
Because of telemedicine, physicians can access patient medical records without being onsite. Some telemedicine providers offer the ability to do data entry using a point-and-click method or video/handwriting recognition. This can cut down on the amount of time that physicians dedicate to administrative tasks. As a result, physicians can see more patients or spend more time with those cases that are more complex.
Roy Schoenberg, the CEO of American Well, believes that doctors, insurers and employers will increasingly inform their patients about the option to use telemedicine, which will help consumers get over many of their fears. If they've already got a relationship with that doctor, a virtual consult might seem like an easier alternative to getting across town to a doctor's office and sitting in a waiting room.
Telemedicine solutions that fall into the remote patient monitoring (RPM) allow healthcare providers to track a patient’s vital signs and other health data from a distance. This makes it easy to watch for warning signs and quickly intervene in patients who are at health-risk or are recovering from a recent surgery, for example. This type of telemedicine is sometimes also called telemonitoring or home telehealth.
Teladoc provides access to board-certified, state-licensed physicians 24 hours a day for non-emergency medical issues such as allergies, bronchitis, pink eye, sinus problems, and ear infection via audio-video technology for consultations regarding medical advice, diagnoses and basic prescription medications.[2] The company bills itself as a telehealth provider due to its function of facilitating "remote house calls by primary care doctors". However, United States Department of Health and Human Services states that the term telehealth covers a broader range including "non-clinical services, such as provider training, administrative meetings, and continuing medical education" and that the term telemedicine means "remote clinical services".[3] Its competitors include PlushCare,[4] American Well, MDLIVE Inc., Doctor On Demand, and Carena.[5][6]

Significant hurdles for more wide-spread telehealth adoption are the limits on reimbursement and the inconsistent payer landscape. In a KLAS-CHIME study from October of last year, over 50 percent of respondents from 104 health care organizations indicated that limits on reimbursement constrict their ability to expand telehealth services for patients. Medicare and Medicaid offer disparate degrees of flexibility while private payers also represent varying levels of funding.
There are many new medical tech terms being used today that the average patient may not be familiar with. For example, a common misunderstanding is that the terms telemedicine, telecare, and telehealth are interchangeable. The truth is that each of these terms refers to a different way of administering health care via existing technologies or a different area of medical technology. To clarify the subtle differences between these three terms, we have provided a detailed definition of each.
Online doctor consultation are rapidly gaining popularity these days as more health insurers offer telemedicine services to help cut costs. Studies have shown that virtual care may effectively used to treat common problems such as flu, acne, deer tick bites, sinus and urinary tract infections. Video doctor consultations can save patients a lot in time and convenience.
