Telemedicine, Communications and Health Information

Maria Zolfo


  • Telemedicine is the use of information technology and telecommunications to provide health services (or support health service provision) over a distance

Aim of this session

  • describe the technologies

  • outline the major new health uses of these technologies


  • Information can be stored and transmitted as either analogue or digital information

    • Analogue technologies are broadcast radio and television, traditional telephone, gramophone records, audio cassette players and, in health, X-ray machines and ECGs

    • Digital technology are computers, audio CDs, digital television, digital mobile telephone and, in health, CT scanning and MRI scanning

It is generally possible to convert information from analogue to digital..

  • A computer modem, e.g., connects a computer (digital) to the telephone network (analogue)

  • The modem converts the digital computer signal into an analogue signal for transmission (and then reverses the process at the receiving computer)

Telecommunication is moving towards digital signals:

  • audio, video, and other data can all be converted to digital signals and then transmitted through the same digital network

  • digital information can be transmitted more accurately; analogue information always degrades more the further it is sent

  • digital signals can be transmitted at extraordinarily fast rates

  • digital signals can be switched and routed more cheaply and flexibly than analogue/signals


  • Wires and cabling: telephone networks built around copper wires and co-axial cables (the bandwidth depends on the type of cable or wire)

  • Fibreoptic cable: very fine glass fibres carrying digital signals as pulses of light (roll-out is expensive!)

  • Radio technologies: radio-waves based (low bandwidth and lack of reliability)

  • Microwave links (similar to radio with higher frequency; high bandwidth)

  • Satellite technology

End-user equipment

  • Telephone

  • Fax

  • Video-conferencing

  • Television

  • Radio

  • Computers


  • LAN (Local Area Network): connects personal computers and mainframe computers over a localized area such as a campus of a hospital, university ...

  • WAN (Wide Area Networks): network which could cover the entire globe, i.e. credit card companies

  • Internet: includes e-mail, file transfer protocol, and access WWW

  • PSTN, PABX,…

Health applications

  • Tele-consultation (telephone, video-conferencing, internet,…)

  • Diagnostic report (digital scanner with computers and software to transmit and regenerate the image)

  • Electronic patient records

Telemedicine ITMA

  • In 2003 the ITMA set up a computer aided training project to guide doctors in the implementation of antiretrovirals (ARVs) and AIDS care in developing countries


To provide continuous medical education in the field of HIV/AIDS for doctors following Short Course on Antiretroviral Therapy(SCART), through a discussion forum on a medical web site, supporting and guiding medical decision making and management of difficult clinical cases

Method of working

  • Expert advice from HIV/AIDS specialists is offered to colleagues in the field through a discussion forum on

Discussion forum …

3 years evaluation (April 2003-March 2006, N: 491 referrals)

Telemedicine, legal issues


  • Any medical or health advice provided and hosted on the website will only be given by medically trained and qualified professionals unless a clear statement is made that a piece of advice offered is from a non-medically qualified individual or organisation


  • The information provided on the website is designed to support, not replace, the relationship that exists between a patient/site visitor and his/her existing physician


  • Confidentiality of data relating to individual patients and visitors to a medical/health website, including their identity, is respected


  • Where appropriate, information contained on this site will be supported by clear references to source data and, where possible, have specific HTML links to that data

  • The date when a clinical page was last modified will be clearly displayed (e.g. at the bottom of the page)


  • Any claims relating to the benefits/performance of a specific treatment, commercial product or service will be supported by appropriate, balanced evidence in the manner

Transparency of authorship

  • The designers of the website will seek to provide information in the clearest possible manner and provide contact addresses for visitors that seek further information or support

  • The Webmaster displays his/her E-mail address clearly throughout the website

Transparency of sponsorship

  • Support for the website will be clearly identified, including the identities of commercial and non-commercial organisations that have contributed funding, services or material for the site

Honesty in advertising & editorial policy

  • If advertising is a source of funding it should be clearly stated
