What is Telemedicine?

Telemedicine can be defined as an advancement in technology that makes it possible for a doctor to take care of patients remotely. This helps the patients to get healthcare services from the comfort of their home, office or beyond. Although this concept took birth in the late 1950s, it has changed rapidly from its inception. Initially, it was designed for people who live in remote places and could not reach hospital in-person. This practice is still being followed for people living in rural areas. But now it has turned out to be a convenient way to provide healthcare services. People have started to avoid doctor-visits because of the danger of being exposed to the hospital environment and also to avoid waiting in the waiting room for hours.Telemedicine began on landline phones. Then with technological advances, now you have a variety of ways to get in touch with a doctor at the time of need. These ways are online portals handled by your family physician, video calling which allows remote consultations, and applications dealt with by companies that manage Telemedicine.Telemedicine lets you discuss your symptoms and medical issues being faced to a healthcare service provider in real-time. By this method, you can get yourself diagnosed, know about the treatment options and receive a valid prescription. To monitor your condition from time-to-time, the doctor can even view your readings from special medical devices remotely.


For most people, Telemedicine is just a two-way video call made to a doctor to receive healthcare services. But the reach of Telemedicine is way beyond than a meagre consultation on a video-call. It encompasses any clinical service provided through telecommunication technology. And hence below are the three types of Telemedicine available today:

1. Real-time medicine: This type of Telemedicine is precisely the first picture that comes to your mind when you hear the word ‘Telemedicine’. Yes, it is the live-interaction between a patient and a doctor on a video call. This type has gained popularity very rapidly. This is because many Telemedicine companies offer a cheap and easy way to consult a doctor remotely and get treated immediately.

2. Remote Patient Monitoring: Through this type, the doctors can monitor a patient’s essential signs and other medical data remotely. The doctors can quickly intervene when there are some warning signs and avoid the risk. But the patient must have health tracking tools related to the disease available at his home, to report the health data to the doctor time-to-time. For example, a diabetes patient should have a glucose tracker and measure their glucose levels and report to the doctor. Remote Patient Monitoring or RPM lets the doctor and patient remain in close communication.

3. Store-and-forward: In this type, a healthcare provider shares a patient’s healthcare profile (lab reports, images, records, videos) to a specialist. These two doctors need not be present in front of each other physically, and the mode of transfer of information used is preferably through email

How does Telemedicine work?

Telemedicine isn’t appropriate for emergencies like a heart attack or kidney failure. But it can be used for minor issues and follow-ups. For example, if you got hurt on vacation and did not know about the medical facilities of that place, you can consult a healthcare provider online. Also, minor throat pain and fever can be relieved through remote consultations. Telemedicine solutions are required to be compliant with the Health Insurance Portability and Accountability Act (HIPAA). This ensures the safety of the patient’s medical data.
