Targeted Interventions to Prevent Chronic Low Back Pain in High Risk Patients

Low back pain (LBP) is a common problem among US adults. Initial episodes tend to be self-limited ("acute"), but some people can progress to a state of persistent pain. Often termed "chronic" LBP (cLBP), this condition can cause prolonged difficulty with most daily activities, including job performance. Most patients see chiropractors or primary care physicians (PCPs) for initial episodes of LBP. This study will compare two approaches for preventing patients with acute LBP (aLBP) from developing cLBP using a cluster randomized trial. Both treatments can be delivered in an outpatient PCP setting. The first approach is to provide PCPs with information regarding a patient's risk of transitioning from aLBP to cLBP and to encourage PCPs to treat patients according to accepted clinical guidelines (Guideline Based Care, GBC). The second approach is to provide the same risk information and have PCPs team up with physical therapists to deliver psychologically-informed physical therapy (PIPT) for those patients determined to be at high risk for transitioning to cLBP (GBC+PIPT). PIPT is designed to help patients identify and overcome physical and psychological barriers to recovery. The 1,860 patients expected to be enrolled as part of quality improvement at five regional sites (Pittsburgh, Pennsylvania; Boston, Massachusetts; Baltimore, Maryland; Charleston, South Carolina; and Salt Lake City, Utah) will start the study when their LBP is in an acute phase. The study's primary aims are to compare the proportions of cLBP and measures of functional ability between the two groups at 6 months. Secondary aims are to measure the referrals to physical therapists and specialists, opioid prescriptions, LBP-related x-rays or MRIs, surgeries, and other medical procedures during a 12-month follow-up period. This study was designed with input from a variety of national and local stakeholders, including patients with LBP, providers, payers, professional organizations, purchasers, and policy representatives.
