Evolution of Health Informatics
Above is the a brief chronology of how HI began its roots. Obviously, without the birth of computers, there will be no Health Information Systems. In 1940, the 1st computer was built called the ENIAC. It was 27 tons in volume and took up 680 sq ft of space. However, it was only in 1950 that HI began to take off with the rise of computers and microchips. The earliest use was in dental projects during late 50s in the US. HI was initially named Medical and Nursing Informatics in the 70s.
The launch of personal computers by IBM in 1982, was one of the most significant turning point in HI development. It was affordable and not bulky. Within 5-7 years, production of softwares and system linkages growing rapidly and HI was pulled into it as well.
Another significant turning point to date, is the public access of internet and world wide web in 90s. It improve information sharing tremendously. Now, in 2000s wireless is the new trend. Anybody could access information from anywhere in the world.
In future, all health information system could one day be connected.
