Pain is a common and very costly public health problem. Common chronic pain conditions are expensive and pervasive, affecting at least 116 million American adults at an annual cost of $560 billion in direct medical treatment costs and lost productivity, and disproportionally affect vulnerable populations. Pain is the primary reason patients seek medical care and, as the first point of contact, primary care providers (PCPs) deliver the majority of that care. Unfortunately, PCPs face many challenges in managing these patients' care and often have little specific training in pain medicine. Yet with proper system support, PCPs are in the best position to coordinate pain management longitudinally. While pharmacotherapy is the predominant treatment approach for many PCPs, this limits the patient's role to taking medication, and he or she can become a passive recipient of care-leading to poor outcomes, potential overmedication, and possible disillusionment with the medical system. Further, increases in opiate prescribing for pain treatment-amidst increasing awareness of adverse outcomes, including addiction-and limited efficacy suggest the importance of broader treatment approaches that focus on patients' improvement of functioning. Although opiates may reduce pain symptoms while prescribed, patients are unlikely to experience significant and sustained improvements without the use of other nonpharmacologic pain management approaches. Medical management of patients with persistent pain and complex problems is often fragmented, which leads patients to seek a wide variety of primary and specialty care services in an effort to manage their pain and related conditions. Such fragmented care leads to poorer outcomes and significantly increases health care costs as patients often receive unneeded diagnostic and medical procedures. While research has identified evidence-based multidisciplinary behavioral treatment approaches that are effective for such patients and can even prevent the disability associated with persistent pain when offered earlier in the course of care, these interventions are rarely available in everyday practice settings and will require data from pragmatic clinical trials to change the care paradigm.

To address these issues, we are conducting a large-scale, mixed-methods, cluster-randomized pragmatic clinical trial throughout three regions of Kaiser Permanente - Northwest, Georgia, and Hawaii. This trial will evaluate the integration of multidisciplinary services within the primary care environment as compared to usual care in these settings. This project embeds 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 is an integrated, interdisciplinary program that guides all pain-related care for intervention patients. This study compares this primary care-based intervention to usual care using systematic, clinic-based assessments. The trial will include up to 1,000 patients and 500 primary care providers (half of each receiving active treatment) with intervention care being delivered by behavioral specialists, nurses, physical therapists, pharmacists, and other affiliated staff. Patients include those 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 intervention brings together elements often available in health plans but organized in a less integrated fashion, and it will ensure flexibility in implementation to best fit individual clinic environments and the needs of chronic pain patients on long-term opiate therapy.
