Abstract
The Oregon State Legislature approved a statewide trauma system in 1985. Regional trauma committees, known as area trauma advisory boards, were prescribed by this legislation. The area trauma advisory board in Region 1 in the Northwest corner of Oregon includes the only 2 level 1 trauma centers in the entire state and began meeting in 1988. The peer review subcommittee, Trauma Audit Group, serves as an interhospital peer review body with a 22-year history as a model of successful systemwide quality improvement committee.
