Telemedicine helps individuals to access healthcare services by the usage of telecommunication and information technology and is completely independent of the distance between the health care expert and patients. Telemedicine is primarily used to overcome distance barriers and improve access to medical services that
would often not be consistently available in distant rural or urban communities. Residents of these areas often have substandard access to specialty healthcare, primarily because specialist physicians are more likely to be located in areas of
concentrated urban population. Recently, telemedicine has widely taken assistance in handling critical care procedures as well.
