Abstract: A system for identifying and selecting a clinical trial, suitable for a specific patient, from a database. Initially, a database of clinical studies, such as the clinicaltrials.gov database, is searched to find the trials specific to a particular disease. All of the clinical trials in the disease-specific area are then extracted from the database. Next, all of the ‘exclusionary criteria’ listed in each trial are then identified and extracted. After identifying all of the criteria cumulatively across all of the clinical trials, a list is made of the criteria having the most redundancy, i.e., the criteria that are common to a predetermined number of the trials. The criteria is then ‘normalized’, or standardized, by assigning a single, consistent category for generating questions that can be answered by either “yes/no”, or selecting one of a small number of predetermined ranges. Finally, the number of criteria is reduced by eliminating the least exclusionary criteria.
