A prototype Web site for immunization knowledge maintenance.

IMM/Web is a prototype Web site designed to assist in the maintenance of the knowledge required to perform computer-based forecasting for childhood immunization. IMM/Web operates in conjunction with IMM/Serve, a immunization forecasting program that takes a child's immunization history and produces recommendations as to which vaccinations are due, and which should be scheduled next. IMM/Serve's domain knowledge is expressed in both tabular and rule-based form. Using IMM/Web, the various tabular forecasting parameters can be modified via the Web. Test cases can then be generated automatically which can be used to help verify the new version of logic. Finally, the test cases can be automatically passed for IMM/Serve to analyze using the newly defined parameters. The IMM/Web project is exploring how the process of updating, customizing, and testing new versions of a computer-based clinical guideline might be performed and guided in an organized fashion via the World-Wide Web.
