Drs. Don Jenkins and Michelle Price from the National Trauma Institute introduce the National Trauma Research Repository (NTRR) an exciting new undertaking that aims to combine data from previous and future trauma research sources, such as PROPPR, PROMMTT, the Glue Grant, DOD, etc.  They also discuss how researchers can access these data and contribute their own data to the ever-growing repository.  Got a project idea for a large national database? Check out NTRR to see if this could work for you. Disclaimer Statement:The National Trauma Research Repository is sponsored by the Department of the Army, Prime award #W81XWH-15.2.0089.
