When electronic medical records are introduced in a network environment, all the information concerning any patient is always up to date, because such information and the health care action are captured at the same time. By example when a Computerized Axial Tomography is performed on a patient, the image obtained is incorporated at once via network, to his electronic medical record, as well as the remarks made by the specialist. When a physician retrieves the medical record of any patient, he is able to see anything written, any clinical test or image performed unto him until that very moment.
