  • A recent study conducted by researchers at the L.V. Prasad Eye Institute (LVPEI) in Hyderabad highlights how teleconsultations, particularly in the field of ophthalmology, can contribute to reducing carbon emissions and mitigating environmental impact.


Environmental Footprint of Healthcare Delivery

  • Vehicular Emissions and Pollution: Traditional healthcare delivery often involves long-distance travel to hospitals, contributing to vehicular emissions and air pollution. In India, where a majority of the population resides in rural areas, this issue is particularly significant.
  • Carbon Dioxide Emissions: The study reveals that teleconsultations led to a substantial reduction in travel distances for patients, resulting in lower carbon dioxide emissions. Across urban and rural settings, telemedicine interventions significantly decreased the carbon footprint associated with healthcare visits.

Benefits of Teleophthalmology

  • Customized Telemedicine for Eye Care: Teleophthalmology, a specialized form of telemedicine focused on eye care, offers remote consultations with ophthalmologists via internet-based video chats.
  • Efficient Follow-up Care: Patients, especially those in rural areas, can receive follow-up care without the need for long-distance travel to tertiary hospitals. This reduces both patient expenses and carbon emissions associated with transportation.

Study Findings and Impact

  • Reduction in Travel Distance: Teleconsultations saved an average of 80 km of travel per rural patient and 1,666 km per urban patient over a three-month period.
  • Carbon Emissions Reduction: Each deferred patient visit resulted in a significant reduction in carbon dioxide emissions, with urban patients saving approximately 176.6 kg of carbon dioxide emissions on average.
  • Financial Savings: In addition to environmental benefits, patients saved on travel expenses, food, and lost wages. Total savings amounted to ₹29,100 for rural patients and ₹3.45 lakh for urban patients over the study period.

About Telemedicine

  • Telemedicine refers to the remote diagnosis and treatment of patients using telecommunications technology.

Regulatory Framework Governing Telemedicine in India

The practice of telemedicine is regulated by various laws and guidelines to ensure patient safety, data protection, and ethical standards. The key components of the regulatory framework include:

  • National Medical Commission Act, 2019 (NMC Act): Provides overarching regulations for medical practice, including telemedicine, by establishing the National Medical Commission.
  • Telemedicine Practice Guidelines (TPG) Issued under the MCI Code: Offers specific guidelines for telemedicine practice, outlining legal and ethical standards for healthcare professionals.
  • Drugs and Cosmetics Act, 1940 (D&C Act) and Drugs and Cosmetics Rules, 1945 (D&C Rules): Regulates the sale and distribution of drugs, including those prescribed during teleconsultations.
  • Information Technology Act, 2000 (IT Act) and related rules: Governs the use of electronic records, data protection, and intermediary liability in telemedicine platforms.
  • Government Policies Regulating Health Data: Ensures the protection and privacy of health data collected and stored during teleconsultations.
  • Telecom Commercial Communication Customer Preference Regulations, 2018 (TCCP Regulations): Regulates commercial communication practices in telemedicine platforms, ensuring compliance with consumer preferences.

Telemedicine Practice Guidelines (TPG)

  • The Telemedicine Practice Guidelines (TPG) were issued in March 2020 in response to the COVID-19 pandemic, providing comprehensive guidance to healthcare practitioners (HCPs) on the practice of telemedicine.
  • Prior to the issuance of these guidelines, telemedicine practice was governed in an ad-hoc manner under various provisions of the Indian Medical Council (IMC) Act, Medical Council of India (MCI) Code, and the Information Technology (IT) Act.

Purpose and Scope:

  • The TPG aim to assist medical practitioners in delivering effective and safe medical care, taking into account current information, available resources, and patient needs, while ensuring patient and provider safety.
  • They provide discretion to HCPs to determine the correct course of action when consulting patients over telemedicine.


  • The TPG are binding only on registered medical practitioners (RMPs), individuals registered to practice with a state medical council as per the provisions of the National Medical Commission (NMC) Act.
  • They do not apply to dentists or practitioners of traditional medicine such as Ayurveda, Unani, Siddha, and Homeopathy. Separate guidelines have been issued for these practitioners by their respective regulatory bodies.


  • While the TPG are only binding on RMPs, it is expected that telemedicine platforms and other stakeholders in telemedicine comply with these guidelines. Compliance with TPG can encourage more RMPs to register on compliant telemedicine platforms.


  • The Telemedicine Practice Guidelines (TPG) provide a structured framework for telemedicine consultations, covering various aspects such as:
  • Legal Recognition: Provides legal recognition to telemedicine as a legitimate form of medical practice.
  • Scope: Specifically defines the scope of telemedicine consultations, excluding non-teleconsultation aspects.
  • Consultation Types: Outlines different types of telemedicine consultations, including video, audio, and text-based consultations.
  • Permitted Situations: Specifies situations where telemedicine consultations are permitted, ensuring appropriate use of the technology.
  • Patient Identification: Establishes protocols for identifying patients and registered medical practitioners (RMPs) prior to consultations.
  • Consultation to Minors: Addresses guidelines for providing teleconsultations to minors, ensuring parental consent and safeguarding minors' rights.
  • Patient Consent: Highlights the importance of obtaining patient consent for teleconsultations and data sharing.
  • Prescribing Medicines: Sets guidelines for prescribing medicines during teleconsultations, ensuring adherence to legal and ethical standards.
  • Liability of Telemedicine Platforms: Clarifies the liability of telemedicine platforms in case of adverse events or malpractice during consultations.

Telemedicine Going Forward

  • Addressing the limitations of telemedicine, particularly in rural and underserved areas, to ensure equitable access to healthcare services.
  • Strengthening regulations around patient consent and data privacy to protect patient information from unauthorized access or misuse.
  • Enhancing safeguards for minors accessing telemedicine services to prevent exploitation or inadequate care.
  • Imposing stricter regulations on prescribing medicines during teleconsultations to prevent misuse or overprescription.
  • Addressing challenges related to the lack of integration of medical records across different healthcare providers to ensure care continuity and comprehensive patient management.
  • Increasing awareness and education about telemedicine services among patients and healthcare professionals to promote its adoption and utilization.
