Telemedicine involves using technology to remotely diagnose, monitor, and treat patients through electronic communication of medical information. It aims to deliver specialized care to patients in remote locations. Key aspects of telemedicine include video conferencing between patients and specialists, monitoring patient vitals in ICUs, and transferring medical data between hospitals for research purposes. While telemedicine provides benefits like early intervention and reduced transportation needs, limitations include potential poor patient-doctor relationships due to lack of in-person interaction and low rates of utilization due to fears around technology.
