In this article, we describe a new computerized method that we created, based on algebra, to check consistency in knowledge bases. We apply this method to sets of medical appropriateness criteria developed using the RAND method. An example of criteria tables for coronary bypass was used to test the method. Different computer tools were developed to facilitate this logical validation. A JAVA program was also developed to display criteria tables in a flowchart format, using any WWW standard browser. Thus, appropriateness criteria can be transformed into effective guidelines for medical practice.
