Key Elements Propelling the Telemedicine Industry’s Expansion

• Healthcare necessity: Chronic diseases are affecting more and more people worldwide. Furthermore, the requirement of healthcare at home has risen due to the geriatric population.
• Technological advancement: Expansion of telehealth solutions is also impacted by prevalence of mobile devices across all age groups and on-demand healthcare apps.
• Easy Diagnosis for patients: Patients are constantly looking for care that is accessible and convenient. Running a telemedicine E Clinic can therefore aid in the timely diagnosis of patients. 
• Patient retention: Besides drawing in new patients, it also enables current patients to regularly receive remote checks and guidance.

Benefits of Telemedicine

• Bridge Gap Between Urban- Rural Healthcare: Telemedicine can improve access to healthcare services in remote and rural areas, where more than 70% of the Indian population resides.
• Step Towards Universal health coverage: Telemedicine can provide a full continuum of essential health services, from health promotion to prevention, treatment, rehabilitation, and palliative care across the life course enabling universal health coverage.
• Cost Reduction: Telemedicine reduces the need for travel and physical infrastructure, which in turn cuts down healthcare costs significantly. 
  • A study published by the L.V. Prasad Eye Institute found that teleconsultations saved patients an average of INR 370 to INR 8,339 per visit in travel and related expenses.
• Decrease in Carbon Footprint: The same study from L.V. Prasad Eye Institute noted that teleconsultations resulted in 1,666 fewer kilometers of travel and a reduction of 176.6 kg of CO2 emissions per patient over three months, contributing significantly to environmental sustainability.
• Efficiency and Time Savings: Telemedicine allows for quicker consultations and follow-ups, which saves time for both patients and healthcare providers. 
  • A survey conducted across several telemedicine platforms in India reported that wait times for teleconsultations were typically less than 10 minutes.
• Enhanced Disease Management: Chronic diseases require ongoing care, and telemedicine facilitates regular monitoring and management without frequent hospital visits. 
  • For diabetic patients, telemedicine interventions have been shown to help in better glycemic control as patients can regularly consult their doctors for adjustments in their treatment plans.
• Expansion of Specialist Care: Many regions in India lack specialist doctors, particularly in fields such as psychiatry and endocrinology. Telemedicine has enabled access to these specialists without the need for patients to travel long distances. 
  • For instance, telepsychiatry has expanded rapidly, providing critical mental health services during the COVID-19 pandemic.
• Support for Health Crises: During the COVID-19 pandemic, telemedicine was pivotal in delivering healthcare while minimizing the risk of virus transmission. It supported the healthcare system by providing a means to triage and treat patients remotely, thus alleviating the burden on hospitals.
