Here is a video from National Journal Online that explains Health IT and how it relates the the current healthcare reform.
Here is a definition of Health information technology:
Health information technology (health IT) would digitize patient records, doctors’ notes, prescription forms, test results and other information that most physicians currently record using dead trees and ink.
As a person who works in the health IT sector, I definitely agree with the video that there are a lot of benefits of health IT but as the same time there are a lot of challenges such as the adoption rate and the amount of technology savvy required.
