(1.0) Introduction
The healthcare industry is facing a historic shift. In the past, receiving medical treatment involved going to a hospital, clinic, or physician’s office in person. But the 21st century brought a mighty substitute — telemedicine. As defined by the World Health Organization (WHO) as the use of information and communication technologies for the delivery of healthcare services to support diagnosis, treatment, and prevention, telemedicine has become a necessary building block of contemporary healthcare.
The COVID-19 pandemic was the ultimate catalyst. Lockdowns, overcrowded hospitals, and fear of infection forced both patients and providers to adopt virtual consultations. Globally, telemedicine usage grew by over 300% in 2020 compared to pre-pandemic levels, according to McKinsey & Company. Even after restrictions lifted, telemedicine continued to be a preferred option for millions.
India has followed suit, though with challenges and triumphs of its own. The Ministry of Health & Family Welfare’s eSanjeevani program has conducted more than 14 crore consultations since it began, demonstrating that telemedicine can actually be scaled to a nation with a population greater than 1.4 billion.
