The Cohort Discovery tool provides researchers the ability to query several sources of patient data. Cohort Discovery is a repository of patient information gathered from multiple sources, including electronic medical records, lab results and demographic data. This information is then de-identified using recognized best practices. Cohort Discovery is powered by i2b2 (Informatics for Integrating Biology and the Bedside).
