Telehealth, also known as telemedicine, is a technology-enabled approach to delivering healthcare services remotely, using telecommunications technology. It includes a wide range of digital solutions that facilitate virtual consultations, remote monitoring, and health-related education & support. It enables healthcare providers to interact with patients in real-time, regardless of their physical location, using video conferencing, messaging platforms, and other communication tools. This technology allows patients to connect with healthcare providers remotely, eliminating the need for in-person visits. At a basic level, telehealth platforms typically involve the following steps:

Firstly, patients initiate the process by scheduling appointments with healthcare providers using online portals or mobile applications. This streamlined approach allows for convenient booking and efficient coordination of care. Following appointment scheduling, patients and providers engage in virtual consultations. Through video conferencing or secure messaging platforms, individuals can communicate in real-time, enabling effective dialogue and information exchange. This virtual interaction bridges the gap between patients and healthcare professionals, ensuring timely access to medical expertise.

Subsequently, telehealth platforms support follow-up and monitoring mechanisms. Providers utilize these platforms to maintain ongoing care management, monitor health metrics, and manage medications for patients. This continuous monitoring and follow-up care contribute to improved patient outcomes and enhanced overall healthcare delivery. In essence, telehealth platforms revolutionize the healthcare landscape by streamlining appointment scheduling, enabling virtual consultations, facilitating medical assessments, and supporting follow-up and monitoring processes. Through these integrated steps, telehealth platforms enhance access to quality healthcare services and promote efficient remote care delivery.
