Health IT is unique:It requires a stronger interaction with a
broad set of stakeholders: Patients Health care professionals Government Vendors Academics
It is defined by the characteristics of the information found in the healthcare segment

Imagine….„ A person comes to the emergency
department complaining of severe pain. The doctor enters the symptoms into the electronic health record system (EHR) . As the doctor tries to determine what’s causing the pain an alert from the health department pops back up on the screen– public health surveillance data advices that there’s been a salmonella outbreak in the region. The patient receives a proper medication and avoids an overnight stay because of the prompt action.”
