A critical early step in leveraging the DW for recruitment purposes is being able to match trial eligibility criteria to discrete and semi-structured data types in the data warehouse, though trial eligibility criteria tend to be written without concern for their computability. We present the multimodal evaluation of a web-based tool that can be used for prescreening patients for clinical trial eligibility. Read more
