The use of a standardized terminology for comparison of free text and structured data entry.

The Minimal Standard Terminology (MST) for gastrointestinal endoscopy, the product of an international effort, is to be been used in a study comparing free text to structured reports of esophagogastroduodenoscopies (EGDs). This requires some assumptions and adaptations in order to map to the MST in a uniform and quantifiable manner. Initial mapping has suggested a number of problem areas which require further investigation.
