Leaf is a self-service web application which allows cohort discovery from clinical data from single or multiple institutions. Cohort discovery involves finding a patient population using different inclusion criteria, such as their age, medical conditions, and procedures they have undergone. This tool removes barriers between clinical data and end-users by making it easy to design and run queries that define these cohorts. The data are from de-identified Electronic Health Records, and the application provides counts and a basic demographic breakdown of the cohort. This information can be used as preparatory-to-research to see if there are enough patients that qualify for a study and to prepare an IRB protocol or grant proposal. The Leaf Data Model shows which variables are available.
Leaf Eligibility:
Leaf is available to all people at Loyola who are eligible to be on an IRB approved study. This means that users must have current Loyola CITI training and HIPAA information security training. Users do not need an approved IRB protocol to access Leaf.
