What is Telehealth and how is it transforming the healthcare sector?

 The World Health Organization mentioned telehealth service and telemedicine among essential services in “strengthening the Health Systems Response to COVID-19” policy. 

According to a new WHO policy, within the optimizing service delivery action, telehealth and telemedicine should be one of the alternative models for clinical services and clinical decision support.

Today, we are living in times where healthcare is of utmost importance for any country across the globe. The Covid-19 outbreak has taught the world how important it is to have a fully equipped medical infrastructure, and using technology to harvest such support is the only possible solution.

What is Telehealth? Telehealth is essentially a merger of technology and healthcare. With the advent of technology and its benefits in Telehealth, I’m sure you all must have heard of:

  • Robotic surgeries
  • Doctors examining case studies over video calls
  • Online communication between doctors and patients
  • Home-based monitoring of patients 
  • Virtual appointments.

In the world of healthcare, all the practices mentioned above are being used more commonly. All of this is possible only because of the Telehealth service.

“In a few years, the idea of receiving medical treatment exclusively at a doctor’s office or a hospital will seem quaint” – Harvard Business Review.

Note – In this blog, we are only talking about the clinical side of Telehealth.

What is Telehealth – Benefits of Telehealth App

To begin with, there are multiple benefits of telehealth.  Telehealth applications would enable quality healthcare services at a more cost-effective price. Other benefits of building a Telehealth app include:

  • Higher Flexibility – Using telehealth service app, professionals in the field have more control over their working hours, and responding to emergencies becomes a lot more effective.

What is Telehealth – How does a Telehealth App Work?

Although every telehealth service application has its logic of working, here is a typical workflow of how a telehealth app works!

  • The patient logs in to the system and creates an account. He then lists out his symptoms to receive a doctor’s consultation.
  • The app assigns the most suitable medical expert nearby for the patient, depending on his health condition.
  • Once the doctor is identified, the patient can schedule a video consultation over the app.
  • Amidst the video consultation, the doctor talks to patients to take updates of the patient’s health, recommends treatment, tests, and so on.
  • After the meeting, the patient pays for the consultation using the app’s built-in payment gateway.
