Health Information Technology (HIT)Health Information Technology (HIT)
Information Technology is the wave of the future for healthcare management
HIT- refers to the technology used to create, transmit, store, secure and manage an individual’s health data.
Currently electronic health data is limited to a single healthcare system, facility or office.
Concept of using IT in Concept of using IT in healthcarehealthcare
The concept of interoperable sharing of health information will authorized entities access (i.e. physician's, billing)
IT use in healthcare is a expanding concept to have an impact on: Enhancing healthcare safety Decrease healthcare cost, and Enhance healthcare quality
The need has been recognized by the private sectors and at the highest levels of government
