To address these issues, we are proposing a mixed-methods, cluster-randomized pragmatic clinical trial that will evaluate the integration of psychosocial services within the primary care environment. This project will implement an intervention into everyday clinical practice flow utilizing assessment measures and intervention staff directly from the clinical care system rather than utilizing a research-developed and administered structure. The intervention will be an integrated program that will guide all care for intervention patients. We will compare this primary care-based intervention to usual care using systematic, clinic-based assessments. During the initial phase, we will pilot the intervention with up to 50 patients in the Kaiser Permanente Northwest (KPNW) region with patients selected by their primary care providers who have non-malignant chronic pain (pain persisting for ≥ 3 months) and who are on long-term opiate therapy for the treatment of their condition. This pilot portion of the project is in preparation for the effective implementation of a large-scale, cluster-randomized pragmatic clinical trial to be conducted throughout three regions of Kaiser Permanente - Northwest, Georgia, and Hawaii comparing this primary care based multidisciplinary intervention to usual care in these settings.
