Short Summary
Main recommendation: Manage most back pain conservatively in primary care and refer at three defined decision points, adjusting by how long the pain has lasted and whether it is improving. Most patients with low back pain will not need referral, and 85 percent of patients with back pain have acute or chronic non-specific back pain without a specific cause, while red-flag findings such as cauda equina syndrome, cancer, osteomyelitis, or radicular symptoms with motor weakness such as foot drop require urgent imaging and immediate referral. The framework is intended to ensure quality care while reducing unnecessary imaging and specialty referrals.
Key Points
- Branch point one, seven to ten days after acute onset: if pain is at least somewhat improved and the patient can cooperate with therapy, refer to physical therapy for a four to six week regimen; if severe pain shows no improvement, refer to pain management or physiatry, though patients with sciatica may warrant waiting another seven to ten days first.
- Branch point two, four to eight weeks after onset: patients who have not improved after the initial plan and a course of physical therapy should be reassessed by the primary care provider around six weeks, with discussion of the case with the treating physical therapist.
- Imaging at four to eight weeks depends on symptoms: non-specific back pain warrants an AP and lateral lumbar x-ray, while ongoing radicular signs or symptoms suggesting a herniated disc or spinal stenosis warrant an MRI.
- Branch point three, three to six months: pain at this stage is considered chronic even if it is a first episode, and spondyloarthropathies such as ankylosing spondylitis should be considered, with rheumatology referral for relevant historical, exam, or imaging features.
- At three to six months without a clear anatomic cause, social and psychological factors such as anxiety, depression, or substance abuse are likely contributors, along with obesity, deconditioning, and low physical activity.
Details Worth Noting
- Concrete instructions: Days 0 to 7 to 10: give positioning advice to relieve pain, movement exercises for intermittent (not constant) pain, treatment with acetaminophen, NSAIDs, and/or muscle relaxants, and ice or heat, then schedule a primary care reassessment in seven to ten days.
- Concrete instructions: Weeks 4 to 8 with persistent non-specific pain: order an AP and lateral lumbar x-ray; if normal, consider referral to physiatry at the UCLA Spine Center, pain management, acupuncture at East West Medicine, chiropractic services, or massage therapy, discussing the patient's preferences first since patients benefit most from treatments they believe will work.
- Concrete instructions: Weeks 4 to 8 with radicular signs suggesting herniated disc or stenosis: order an MRI; if findings correlate with history and exam, refer to physiatry at the UCLA Spine Center, pain management, or spine surgery, with patients not wanting surgery directed to pain management or physiatry for options such as epidural steroid injections.
- Concrete instructions: For suspected spondyloarthropathy at three months or more, order an AP pelvis x-ray, HLA-B27 lab test, and ESR and CRP at the time of rheumatology referral in most cases.
- The video notes that sciatica may take longer to improve, which is the reason for the extra seven to ten day wait at the first branch point.
- Chronic pain management centers on identifying and treating psychological issues and combining supportive treatments and coping strategies; pain management and physiatry at the UCLA Spine Center are named as specialty options that can be developed alongside primary care.
Bottom Line
Most back pain can be handled in primary care with timed reassessments, and referral should follow specific findings and durations rather than habit, with red flags triggering immediate action.
