Aging Back Clinics

Degenerative disease of the lumbar spine is ubiquitous in older adults, but low back pain is not. Treatments that focus exclusively on degenerative spine disease, such as spinal injection and surgery, have resulted in rising costs and exposure to potentially life-threatening morbidity but outcomes have not improved. The investigators posit that to improve treatment outcomes for older adults with chronic low back pain (CLBP - back pain that has been present on at least half the days for at least 6 months), the condition should be approached as a syndrome, that is, a final common pathway for the expression of many contributors, in the same way that geriatricians approach the evaluation and treatment of delirium and falls. Using this model, the lumbar spine is considered a weak link, but is rarely the sole treatment target. Conditions that commonly contribute to pain and disability in older adults with CLBP include hip osteoarthritis, fibromyalgia, anxiety, maladaptive coping, and myofascial pain, each of which is associated with specific evidence-based treatments. Because such conditions are not routinely evaluated in patients with CLBP, it is perhaps not surprising that first line treatments that do not specifically target multiple contributors (e.g. spine-focused physical therapy and analgesics) often provide suboptimal treatment outcomes. This often results in continued treatment-seeking including potentially toxic medications and invasive, expensive, and potentially life-threatening procedures such as complex spinal fusion.

The central question that the proposed randomized trial is designed to answer is: What is the efficacy of caring for older adults with CLBP in Aging Back Clinics (ABC), where the patient is first treated as an older adult, and second as a patient with CLBP, compared with usual care (UC)? The investigators have developed evidence and expert-opinion based guidelines for the evaluation and treatment of 12 key contributors to pain and disability in older adults with CLBP. The investigators' prior work also supports the commonplace nature of multiple contributors to CLBP in older Veterans and the feasibility of delivering patient-centered comprehensive care that follows the investigators' published guidelines. The investigators now wish to implement these guidelines in the investigators' ABC clinics and compare this approach to that of UC in older Veterans. Proof of the hypotheses could significantly impact patient care by reducing pain and disability and identifying key conditions whose treatment could prevent the pursuit of invasive treatments and their associated potential morbidity and cost.

About 450 Veterans age 65-89 with CLBP will be recruited from primary care provider practices at 3 VAs - VA Pittsburgh Healthcare System, Dallas VA, and Richmond VA to meet a target randomization of 330. Individuals will be randomized to receive either ABC care or UC and they will be followed for one year. Those in ABC care will be referred to a generalist (e.g., geriatrician, physiatrist, rheumatologist) that has been identified and trained in a structured assessment to identify the conditions for which evidence and expert opinion-based algorithms have been created. Usual care will not be constrained. Outcomes will be assessed at baseline and over the telephone at three later time points: 6 months, 9 months and 12 months. Health Care Utilization will be assessed monthly. Gait speed, a strong predictor of morbidity and mortality in older adults, will be measured at baseline. The proposed clinical trial has the potential not only to improve pain-related disability, but also to reduce morbidity, increase quality of life, and limit healthcare utilization.
