The U.S. spends over $2.9 trillion on healthcare every year, more than any other developed nation. On top of that, an estimated $200 billion of those costs are avoidable, unnecessary spending. Telemedicine has the power to cut our healthcare spending by reducing problems like medication non-adherence and unnecessary ER visits, and making typical doctor visits more efficient.

Remote surgery or telesurgery is performance of surgical procedures where the surgeon is not physically in the same location as the patient, using a robotic teleoperator system controlled by the surgeon. The remote operator may give tactile feedback to the user. Remote surgery combines elements of robotics and high-speed data connections. A critical limiting factor is the speed, latency and reliability of the communication system between the surgeon and the patient, though trans-Atlantic surgeries have been demonstrated.
Healthcare systems, physician practices, and skilled nursing facilities are using telemedicine to provide care more efficiently. Technologies that comes integrated with telemedicine software like electronic medical records, AI diagnosis and medical streaming devices, can better assist providers in diagnosis and treatment. The latter allows providers to monitor patients in real-time and adjust treatment plans when necessary. Ultimately, this leads to better patient outcomes.
Today, 95 percent of Americans own cell phones and 77 percent own smartphones. These and other mobile devices can be leveraged to promote better health outcomes and increased access to care. mHealth or mobile health refers to healthcare applications and programs patients use on their smartphones, tablets, or laptops. These applications allow patients to track health measurements, set medication and appointment reminders, and share information with clinicians. Users can access hundreds of mHealth applications including asthma and diabetes management tools as well as weight loss or smoking cessation apps. Additionally, mobile devices allow users to schedule appointments and communicate with providers via video conference and text message.
The benefits posed by telehealth challenge the normative means of healthcare delivery set in both legislation and practice. Therefore, the growing prominence of telehealth is starting to underscore the need for updated regulations, guidelines and legislation which reflect the current and future trends of healthcare practices.[2][23] Telehealth enables timely and flexible care to patients wherever they may be; although this is a benefit, it also poses threats to privacy, safety, medical licensing and reimbursement. When a clinician and patient are in different locations, it is difficult to determine which laws apply to the context.[41] Once healthcare crosses borders different state bodies are involved in order to regulate and maintain the level of care that is warranted to the patient or telehealth consumer. As it stands, telehealth is complex with many grey areas when put into practice especially as it crosses borders. This effectively limits the potential benefits of telehealth.[2][23]

ISDN Primary Rate Interface (PRI): An ISDN interface standard which operates using one 64K data channel and 23, 64K channels. When the right multiplexing equipment is used, the user can selected the IDN PRI channels for a video call. As an example, if a user would like to have his videoconference at 384K bandwidth, the multiplexer can be instructed to utilize channels 1-6 (6 x 64k= 384k). It is actually quite importance since usually the user pays charges that are based on how many 64k channels get used on a videoconference. So the fewer channels that have to be used to get a quality video signal, the lower the cost of the call will be.
In 1967 one of the first telemedicine clinics was founded by Kenneth Bird at Massachusetts General Hospital. The clinic addressed the fundamental problem of delivering occupational and emergency health services to employees and travellers at Boston's Logan International Airport, located three congested miles from the hospital. Over 1,000 patients are documented as having received remote treatment from doctors at MGH using the clinic's two-way audiovisual microwave circuit.[13] The timing of Bird's clinic more or less coincided with NASA's foray into telemedicine through the use of physiologic monitors for astronauts.[14] Other pioneering programs in telemedicine were designed to deliver healthcare services to people in rural settings.[citation needed] The first interactive telemedicine system, operating over standard telephone lines, designed to remotely diagnose and treat patients requiring cardiac resuscitation (defibrillation) was developed and launched by an American company, MedPhone Corporation, in 1989. A year later under the leadership of its President/CEO S Eric Wachtel, MedPhone introduced a mobile cellular version, the MDPhone. Twelve hospitals in the U.S. served as receiving and treatment centers.[15]

Medicaid: Every state Medicaid plan specifically covers at least some telehealth services, however states vary greatly in their coverage.  State-specific information is available on www.atawiki.org and the 50 State Telemedicine Gaps Analysis: Coverage and Reimbursement. ATA has challenged each state to fully cover telemedicine to increase coverage while simultaneously reducing service costs.
The term telehealth includes a broad range of technologies and services to provide patient care and improve the healthcare delivery system as a whole. Telehealth is different from telemedicine because it refers to a broader scope of remote healthcare services than telemedicine. While telemedicine refers specifically to remote clinical services, telehealth can refer to remote non-clinical services, such as provider training, administrative meetings, and continuing medical education, in addition to clinical services. According to the World Health Organization, telehealth includes, “Surveillance, health promotion and public health functions.”
Inability to prescribe medications: Many states generally do not allow online prescribing (not to be confused with e-prescribing) without an established relationship between the physician and patient. A physical examination or evaluation may be required before a physician can write a prescription for a patient, but there are inconsistencies in state laws as to what constitutes a physical examination.

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.
In-office visits and overnight stays at healthcare facilities can be difficult for individuals in poor health. Telehealth services reduce hospital readmission rates by enabling doctors to monitor patients outside the office. Because of this, many hospitals have already started to include some form of remote monitoring as part of their post-discharge plans. By equipping patients with wearable devices or other wireless technologies, clinicians can monitor vital signs and symptoms and adjust care as needed without an in-office visit. Alignment Healthcare, for example, developed a program to remotely monitor chronically ill and recently discharged patients and reduce 30-day readmission rates. Enrollees were given a package of Bluetooth-enabled monitoring equipment, including a Samsung tablet, blood pressure cuff, pulse oximeter and scale.

Today’s patient lives in an increasingly connected world and expects a different kind of care experience. Telemedicine engages patients by allowing them to connect with their doctor more frequently, in a convenient way. That means more questions asked and answered, a stronger doctor-patient relationship, and patients who feel empowered to manage their care.

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.

Internet Protocol (IP): The protocol for sending data from one computer over the Internet to another. Every computer that is on the Internet has one address at least that identifies it uniquely from all of the other computers that are on the Internet. Internet Protocol is a connectionless form of protocol, meaning there isn’t a connection that is established between the two points that are communicating with one another. A videoconferencing system’s IP address is its telephone number.


Unlike online prescription scams which pop up from time to time, online medical consultations are completely legit. These services are provided by real doctors who speak with you, usually by video conference, and then send your prescription to a local pharmacy in your area for pickup. You can skip scheduling conflicts, doctor office waiting rooms, and long lines at the drop-of counter in the pharmacy.
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. 
Where telemedicine refers specifically to the practice of medicine via remote means, telehealth is a blanket term that covers all components and activities of healthcare and the healthcare system that are conducted through telecommunications technology. Healthcare education, wearable devices that record and transmit vital signs, and provider-to-provider remote communication are examples of telehealth activities and applications that extend beyond remote clinical care.
Multi-point Teleconferencing – This is the process of connecting multiple users from different sites. It allows electronic communication between the users as well as transmission of video, voice and data between computers and systems. Multi-point teleconferencing requires the use of a multi-point control unit or the bridge to be able to connect the different sites for the videoconference.
This system enabled wireless transmission of ECG from the moving ICU van or the patients home to the central station in ICU of the department of Medicine. Transmission using wireless was done using frequency modulation which eliminated noise. Transmission was also done through telephone lines. The ECG output was connected to the telephone input using a modulator which converted ECG into high frequency sound. At the other end a demodulator reconverted the sound into ECG with a good gain accuracy. The ECG was converted to sound waves with a frequency varying from 500 Hz to 2500 Hz with 1500 Hz at baseline.
Children under 3 with a fever need to be seen immediately by a doctor in an office based setting. Children under 12 with ear pain can be treated if the pain is due to a virus (e.g. Colds), allergies, or an external infection. If there is a high likelihood it is a bacterial inner infection that needs antibiotics, they should be seen immediately by a doctor in an office based setting.
