Telemedicine & Tele-Health Services

What is Telemedicine?

“The delivery of health care services, where distance is a critical factor, by all health care professionals using information and communication technologies for the exchange of valid information for diagnosis, treatment and prevention of disease and injuries, research and evaluation, and for the continuing education of health care providers.”

Tele-Health

“The delivery and facilitation of health and health-related services including medical care, provider and patient education, health information services, and self-care via telecommunications and digital communication technologies.”

Telemedicine

Technology Used and Mode of Communications

Multiple technologies can be used to deliver telemedicine consultation. The three primary modes are: Video, Audio and Text. Each mode has its own strengths, limitations and suitable contexts for delivering diagnosis and healthcare advice.

Telemedicine provides safety to medical professionals from contagious diseases. However, it cannot completely replace physical examination that requires palpation, percussion or auscultation. New technologies may reduce this limitation in the future.
