Leaf

Leaf is a self-service tool which provides UW investigators with a user friendly interface for querying the electronic health system records within UW Medicine. Unlike other cohort discovery tools, Leaf interacts directly with live data from the electronic health system and can generate reports in real time. Electronic health system data can help investigators answer a variety of questions about patient populations including medical and demographic information, clinical processes, and department statistics. Leaf can produce results that are identifiable or de-identified data sets. In order to access identified data, you will first have to obtain IRB approval for human subjects research.
