Databases and decision system for diagnosis of congenital heart disease

In paediatric cardiology a database is indispensable in order to conduct more extensive and detailed investigations. A database should contain large amounts of data since even the most ordinary information from medical history and status praesens of a patient provides better understanding of the disease. A particular problem is coding of information because of the difference between qualitative and quantitative information. In our study database served as ‘raw data’ in developing for diagnostic decisions in case of congenital heart disease (CHD). In this work we shall describe the collection of information/data (Part one) and the system of decision analysis in the process of diagnosing congenital heart disease (Part two). Large amounts of data, both qualitative and quantitative could be collected using following methods: 1. classification of data 2. coding of data by means of codex of chifres 3. storing (retrieving in large systems) 4. data processing using suitable statistical programmes (Part one).
