Telemedicine Systems

Telemedicine Systems - Digital Doctoring Defined

• Delivery of healthcare services using ICT where distance is a barrier. Encompasses diagnosis, treatment, prevention, research, and health education.
• Key System Types:
  • Store-and-Forward (Asynchronous): Data (images, reports) sent for later review.
  • Real-Time (Synchronous): Interactive audio/video consultations.
  • Remote Patient Monitoring (RPM): Continuous physiological data tracking.
• Primary Goal: Improve healthcare accessibility, quality, and cost-effectiveness.

⭐ Telemedicine Practice Guidelines (India, 2020) by MoHFW & MCI empower RMPs for teleconsultation, defining permissible drug lists (Lists O, A, B).

System Components - Tech & Teams Tango

• Core Elements: Hardware, Software, Connectivity, Personnel.
• Technology Stack:
  • Patient-End:
    • Devices: Smartphones, tablets, computers.
    • Peripherals: Digital stethoscopes, BP monitors, glucometers, pulse oximeters.
  • Provider-End:
    • Workstation: Computer, high-resolution camera, microphone.
    • EMR/EHR Integration: For seamless data flow.
  • Communication Link:
    • Network: Reliable internet (Broadband, 4G/5G).
    • Platform: Secure video conferencing, messaging applications.
    • Data Security: Encryption, adherence to standards (e.g., DICOM, HL7, ISO 13131).
• Human Capital - The "Tango":
  • Clinical Team: Teleconsultants (doctors, specialists), Tele-nurses, Tele-technicians.
  • Support Team: IT personnel, Coordinators, Administrative staff.
  • Patient Facilitators: Often at remote sites (e.g., Community Health Officers at HWCs).

⭐ Telemedicine Practice Guidelines (India, 2020) mandate that consultations must be provided by a Registered Medical Practitioner (RMP).

Delivery Models & Apps - Virtual Visit Varieties

• Delivery Models:
  • Synchronous (Real-time): Live interaction.
    • Video (e.g., eSanjeevaniOPD)
    • Audio calls
    • Chat
  • Asynchronous (Store-and-Forward): Data sent, reviewed later.
    • Secure messaging, email
    • Teleradiology, telepathology
    • Remote Patient Monitoring (RPM) data
• Virtual Visit Types & Platforms:
  • Doctor-to-Patient (D2P/B2C): Direct consultation.
    • Apps: Practo, Apollo 24/7, eSanjeevaniOPD.
  • Doctor-to-Doctor (D2D/B2B): Specialist consults, tele-mentoring.
    • e.g., Project ECHO, Tele-ICU.
  • Hub-and-Spoke Model: Specialist hub serving multiple peripheral centers.
    • e.g., eSanjeevani Ayushman Bharat-Health and Wellness Centre (AB-HWC).
  • Remote Patient Monitoring (RPM): For chronic disease management.

⭐ eSanjeevani, India's national telemedicine platform, has two main variants: eSanjeevaniOPD (patient-to-doctor) and eSanjeevaniAB-HWC (doctor-to-doctor, hub-and-spoke).

Indian Landscape - Rules & Roadblocks

• Guidelines: Telemedicine Practice Guidelines, 2020 (BoG-MCI, MoHFW, NITI Aayog).
• Eligibility: Registered Medical Practitioners (RMPs) only.
• Consent: Patient's explicit/implied consent mandatory.
• Prescription:
  • List O (OTC), List A (new/follow-up), List B (chronic refills).
  • Prohibited: Narcotics, Schedule X drugs.
• Care Quality: Equivalent to in-person; RMP accountable.
• Data Management: Record keeping, privacy, security essential.
• Roadblocks:
  • Digital divide (literacy, connectivity).
  • Data security & privacy concerns.
  • Reimbursement & interoperability issues.

⭐ Telemedicine consultations can be initiated by patient, caregiver, or RMP; however, RMPs can choose the appropriateness of telemedicine for a case and can refuse consultation if they deem it unsuitable for remote handling.
