UN/EDIFACT based medical documentation and messages.

New documentation and messages conforming to the rules of EDIFACT are created and an attempt is made to follow internationally standardised and wordwide available commercial experience. A set of medical documents, aligned with United Nations Layout Key for trade documents is designed. The approach is to develop a set of paper documents and to standardise the data which are filled in these documents. There is a possibility to fill the data directly in medical documents and to print them from the Clinical Information System in our University Hospital.
