Medical Informatics
"Medical informatics is the rapidly developing scientific field that deals with resources, devices and formalized methods for optimizing the storage, retrieval and management of biomedical information for problem solving and decision making." - Edward Shortliffe

The background
French word informatique (mid 70’s)
Processing the clinical information
May be recognized as technological
parallel to biological sequences
A long list of advantages

The new to it…
To many, it is merely the new way of doing the old things…
To others, it is too advanced
The realm of fact is not a debate of new or old…
The paradigm shift is the set of gathered advantages!

This is how it worksPhysical Connectivity Channels: Telephone lines, ISDN, Fiber Optic Cables, Coaxial cables, etc.
Virtual Channels: Satellite
Transmission (radio waves), Terrestrial Transmission and
reception (radio and infra red waves), etc.

Real-Time Synchronized
The clinician can also ….
View the patient on the screen
Hear and talk, Access details of
medical record,and Zoom in / zoom out of
the images of lesions, etc.
How are you feeling today, Mr. Patient
Definitely better!! Thanks to
your telemedicine !!

Email and WWW based HealthCare support
HealthCare Informatics: The big picture 23© Zaman© Zaman
As in Question answer sessions for common
diseases Web based, often store and forward,
primary or second opinions Well known - Web MD, Medline and
TeleMedPak Articles of general interest on the WWW Can cost more, unless financially
superior to conventional healthcare services
