What Is Telemedicine?

Simply defining the term, telemedicine means healing at a distance with the use of technology to improve patient outcomes. Telemedicine uses digital tools and telecommunication technology to solve medical problems at a distance, as well as enables the opportunity to explore innovative healthcare technologies to improve the quality of care. 

According to the American Telemedicine Association, 

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

According to WHO,

“The delivery of health care services, where distance is a critical factor, by all health care professionals using information and communication technologies for the exchange of valid information for the diagnosis, treatment, and prevention of disease and injuries, research and evaluation, and for the continuing education of health care providers, all in the interests of advancing the health of individuals and their communities.” 

Key elements of telemedicine are,

  • Intending to enhance patient outcomes
  • Presenting quality and value-based healthcare services
  • Utilizing Information and Communication Technology
  • Exploring various digital technologies
  • Overcoming geographic barriers

Origin And History Of Telemedicine

the evolution of telemedicine

Roots of telemedicine lie in the evolution of telecommunication technologies in ancient times when humans used to communicate at a distance through visible signals or sound patterns i.e. using fire or drum to send a message. Unless and until, a series of electronic communication technologies invented in the 18th century. The United States of America implemented the first intercity telegraph service between Washington and Baltimore in 1844. Later on, the military also used telegraph service to order medical supplies and other lists during the world war. So, that was just the origin of using the telegraph in the early decades for medical services. 

In 1876, Alexander Graham Bell patented the invention of the telephone, a device used for electronic communication transmission. As he continued investigating further, telecommunication was upgraded with long-distance telephone links, multiple telephone lines, circuits, and automatic switching systems. Sharing images and audio signals became possible later on due to technological innovations, including radio transmissions in 1887 by Henry Rudolf Hertz. Major city hospitals installed telephones, and doctors could talk to their patients to give medical advice from a distance. Even talking with other physicians became possible with this innovation.

Development of Telemedicine

The 19th century was a decade of innovations. Transmitting instrumental readings as stethoscope over telephone or radio began in the first half of 1900. Dr. Hugo Gernsback, the pioneer of radio and publishing, predicted the future of radio communication as well as a device in 1924, which would enable doctors to consult their patients through a video screen and touch them with robotic arms at a distance. That was his prediction of telemedicine. Later on, many hospitals, as well as NASA, the military used telemedicine. 

The University of Nebraska used video telemedicine consultation for the first time in 1959 to transmit neurological examinations, followed by other programs such as x-rays, ECGs. Later on, NASA also used telemedicine for its astronauts to provide healthcare in space in 1960. Various telemedicine applications were developed afterward to provide virtual care for rural areas.

The rise of the internet has changed the face of telemedicine after the 1990s. Considering the potential for telemedicine, the US government also funded projects related to telemedicine. Various telemedicine policies, systems, software, and applications were developed to provide care at a distance. 

Today’s Telemedicine – Current State

Today’s fast-changing technology has upgraded telemedicine more than ever before. Telemedicine has become advanced and easy to use through various technology-led tools such as smartphone apps, cameras, video conferencing, and wearable devices. Video connections have become high resolution, faster, and more reliable to interact on smartphones now. 

Telemedicine software for providers is helping to bridge the gap between patients and physicians to enable quality care. Most of the healthcare organizations use telemedicine software for diagnosis and to streamline clinical workflow. The adoption of telemedicine has increased over the last five years. Because today’s patients want immediate care and do not want to waste time in the waiting room. 

The innovative concept of virtual care delivery has many aspects, such as remote monitoring, e-prescription, virtual appointments, and consultations. It has improved the quality of providing medical care with a range of applications and healthcare tools. Exchanging medical information has become possible in various formats like text, image, video, document, or pdf. Today’s telemedicine meets the requirements of healthcare consumers as well as professionals by overcoming geographic barriers. It is totally different from the traditional tools for providing care. 

Telemedicine software for hospitals focuses on preventive care and offers new means to communicate with healthcare consumers. By increasing the convenience to access healthcare services when needed, it reduces the potential travel time and readmissions time of patients. On the other side, it also improves the care delivery process for practitioners by allowing them to engage with patients through audio or video call, thereby enhancing follow up care and improving patient outcomes. Furthermore, today’s white label telemedicine platform addresses all security and HIPAA concerns to protect health information online. 

Telemedicine has several approaches to provide medical treatment. Refer to this blog to understand the same.

Telemedicine vs. Telehealth

Often both the terms are used interchangeably; the concept of the two terms is different. No doubt, they are similar in many aspects, but each concept has its own way of providing healthcare services. So is it telemedicine or telehealth? Telehealth covers the clinical and non-clinical healthcare services at a distance, while telemedicine covers remote clinical services only.  

Telemedicine is focused on providing only education and medical care, diagnosis, and treatment-related services at a distance. It is treatment-centric and limited to the delivery of care only. It uses telecommunication technology to provide medical care. Conducting diagnostic tests, monitoring patients’ progress after treatment, video consultations with specialists are examples of telemedicine. 

On the other hand, telehealth includes a wider variety of healthcare services at a distance beyond providing only medical care. It consists of all healthcare stakeholders like physicians, care teams, nurses, specialists, or pharmacists. It uses multiple telecommunication technologies to support healthcare management, literature, and access to medical knowledge. Health education, ECG, virtual medical consultations, patient monitoring, managing clinical workflows, providing training, and conducting administrative meetings are examples of telehealth.

Telemedicine Legal And Regulatory Aspects

Implementing telemedicine is encouraged worldwide by the government by strictly adhering to the legal aspects as mentioned below:

  • License

    As telemedicine can overcome the geographical boundaries to provide virtual care, it raises legal and regulatory concerns related to licensing. However, most regions require physicians to be licensed for practice. It becomes difficult for providers to identify and verify their patients’ locations at the time of consultation. Hence, it is essential to get the license to provide services in specified regions. Furthermore, cross-state licensing also allows practitioners to provide telemedicine services in a neighboring state without having a license in that region. But it requires additional documentation before practicing in a nearby area of the country. 

  • Physician-Patient Relationship

    As per many regions’ standard policy, the usage of telemedicine is prohibited in case the provider has not examined patients through an in-person visit. Both of them have at least one in-person visit. While some regions require a specific form of communication with patients before providing telemedicine. This regulation is changing in a few countries with a transformation in healthcare.

  • Medical Malpractice Coverage

    Telemedicine offers sophisticated ways of providing remote care. But providing remote care in different regions has different standards of care. Some regions have the same rules as in-person visits, while others have more restrictive standards. Hence, it is essential to review medical malpractice insurance policies to provide telemedicine services carefully. 

  • Tele-Prescribing

    When it comes to providing an online prescription, many regions have enacted tele-prescribing regulations, such as in-person physical examination of medications. Therefore, providers need to understand the state legislations of prescribing medications through telemedicine. 

  • Reimbursement Policy

    Telemedicine implementation varies region-wise in terms of providing reimbursement for delivering healthcare services. Likewise, private payor coverage for telemedicine also varies greatly. Private payers reimburse the same amount as in-person medical services in many regions. Reviewing state rules and regulations before billing is of utmost importance for any provider. 

  • Privacy and Confidentiality (HIPAA)

    HIPAA privacy and security rules apply to most healthcare entities, as the act sets the standard for securing patients’ health information, stored or transferred by electronic channels. As per the law, providers must strictly adhere to the main three compliances – administrative, physical, and technical. Hence, the provider should ensure to sign a business agreement with the telemedicine vendor that he is providing a fully encrypted telemedicine solution that protects the privacy of patients’ data. 


Telemedicine is one of the valuable platforms that makes remote consultation and care possible from a distance. Accessibility, convenience and cost-effective treatment through telemedicine have advanced the healthcare industry. The use of telecommunication and smart technologies for patient monitoring, consultation, diagnosis, and medication has reduced the gap between supply and demand for healthcare services. Although it includes economic, legal, ethical, and technical issues to survive in the market, telemedicine is a lucrative concept for all healthcare organizations.
