TelemedicineWe are almost relying on digital for communicating, collaborating, and conducting major business functions in this coronavirus pandemic. In every field, the ability to adapt virtual considered as ‘essential’ rather than any ‘backup’ plan. From eLearning to eHealth and from virtual offices to online events, technology has helped everyone to achieve better accessibility, speed, and efficiency.

Technology is proven indispensable for the majority of the fields including healthcare. There are more advanced, accessible, and accurate solutions that help health professionals, governments, hospitals, researchers, and doctors to study, diagnose, and access better resources and services.

Like education, better healthcare is every human’s right, and both developed and developing countries are making every effort to make it affordable, accessible, and cost-effective.

History Of Telemedicine: Healing From A Distance

The World Health Organization (WHO) describes telemedicine as “Healing from a distance.”

This refers to the freedom of getting treatment without stepping out from your home to visit a doctor.

The first application of Telemedicine applied in 1905 by a Dutch physician as mentioned in this book, titled History of Telemedicine: Evolution, Context, and Transformation, by Gary William Shannon And Rashid Bashshur.

According to the book or several other resources over the web, the transmission of radiographic images started in the 1950s in the United States. With the never-ending changes in technology and advances in the healthcare industry, telemedicine observed concurrent evolutions over time.

What Are The Types Of Telemedicine?

There are three types of telemedicine delivered to patients and these are:

  • Remote Monitoring

It involves the use of technological healthcare devices to monitor the health and very useful in the management of chronic conditions such as heart disease, diabetics, asthma, and many more. It is also known as ‘telemonitoring’ that allows health professionals to monitor patients’ activities and conditions remotely.

  • Real-Time Interaction

This is more like medical advice, anytime, anywhere without visiting a doctor in-person. Real-time video calls, phone calls, or texts can be used for consulting, discussing issues, seeking primary advice, follow-up meetings, or checking conditions of chronic illness. There are special apps for this purpose where patients and providers use secure software to see and hear each other. This method is very popular for accessing rapid primary healthcare.

  • Store And Forward

In this type of Telemedicine service, all the history, diagnosis, images, tests, and videos are stored and forwarded to healthcare providers who use this information to treat patients after a period of time. This is often useful for rural areas where patients need a specialist or advanced health care at another location and this information can be shared with them. This can save a lot of time and cost.

Fun Fact: Telemedicine first started on landline telephones.
