Screening, brief intervention, and referral to treatment for pain management for veterans separating from military service: study protocol of a hybrid type 2 study testing implementation facilitation versus training-as-usual.

Background: Veterans transitioning to civilian life often have chronic pain from service-related musculoskeletal disorders (MSD) with higher risk for substance misuse. Many seek VA (Department of Veterans Affairs) compensation for MSD. Use of Screening, Brief Intervention, and Referral to Treatment for Pain Management (SBIRT-PM) by VA Post-9/11 Military2VA (M2VA) case managers presents an opportunity to engage these veterans in VA pain care and address substance misuse.
