STRIDE Anonymous Patient Cohort Discovery Tool

View Larger | View Demo

The STRIDE Anonymous Patient Cohort Tool provides an easy to use, self-service, way for Stanford researchers to query the STRIDE Clinical Data Warehouse (CDW) to answer the question "Does the STRIDE CDW contain a cohort of patients with these characteristics?". Search criteria can include patient demographics, ICD coded diagnoses, ICD and CPT coded procedures, laboratory test results and text within clinical documents, including surgical pathology reports and radiology reports. In response to a query, the Cohort Tool returns the approximate number of patients, if any, matching the search criteria. No patient identifiers or clinical data is revealed. Researchers can store their cohort searches online and later meet with Center staff to discuss how they might review and extract clinical data on patient cohorts for research purposes. Release of data from the STRIDE CDW for research purposes requires Stanford IRB approval.

In Spring 2007, the Center conducted a successful beta test of the STRIDE Anonymous Patient Cohort Discovery Tool, searching a limited subset of the STRIDE CDW. In early 2008 the Center for Clinical Informatics will release an enhanced version of the STRIDE Anonymous Patient Cohort Discovery Tool searching a much larger volume of CDW data.
