Telemedicine
 

Telemedicine is the use of Information Technology (IT) to transmit medical information between different locations via telecommunications media for healthcare service delivery, Patient Education and Health Care Provider Education to improve patient care.

This broad definition that covers many diverse applications: teleconferencing, remote consultation, transfer of patient’s records, remote data collection and diagnosis, Tele-Education and more.

Telemedicine may be as simple as two health professionals discussing a case over telephone, or as sophisticated as using satellites to transmit a consultation between healthcare providers located in two countries, using videoconferencing equipment. Medical data can contain images like X-Rays, MRI, CT Scans, Ultra-sound , Blood slide microphotographs, ECG recordings, Audio–Video clippings etc. Transfer of these images and text data may utilize a variety of telecommunications technology like telephone lines, ISDN, internet, intranets, LAN, WAN and satellites.

Telemedicine may have been in prominence in the past four years, but in reality telemedicine has been in use in some form or other for over thirty years. The National Aeronautics and Space Administration (NASA) played an important role in the early development of telemedicine. Many of the initial telemedicine endeavors involved transfer of images over microwave and audio frequency ranges. Astronauts in space were monitored from the spacecraft as well as their spacesuits during their missions.


Telemedicine is now becoming useful in a many spheres of medicine viz. Dermatology, Oncology, Radiology, Surgery, Cardiology, Psychiatry, Gynaecology, Paediatrics and Home Health Services for remote areas where no such specialist is available.
