['In 2007, the American College of Surgeons (ACS) Committee on Trauma implemented a requirement that Level I trauma centers must have a mechanism to identify patients who are problem drinkers and the capacity to provide an intervention for patients who screen positive. Although the landmark alcohol screening and brief intervention (SBI) mandate is anticipated to impact trauma practice nationwide, a literature review revealed no studies that have systematically documented SBI practice pre-ACS requirement.', 'Trauma programs at all US Level I trauma centers were contacted and asked to complete a survey about pre-ACS requirement trauma center SBI practice.', 'One hundred forty-eight of 204 (73%) Level I trauma centers responded to the survey. More than 70% of responding centers routinely used laboratory tests (eg, blood alcohol concentration) to screen patients for alcohol and 39% routinely used a screening question or standardized screening instrument. Screen-positive patients received a formal alcohol consult or had an informal alcohol discussion with staff members approximately 25% of the time.'] Do nationwide survey of alcohol screening and brief intervention practices at US Level I trauma centers?
