Assessment and Management of Back Pain

Immediate Red Flag Assessment

The American College of Physicians recommends screening for emergent conditions such as cauda equina syndrome, malignancy risk, infection indicators, and fracture risk in patients with back pain 1, 2
Patients with a history of cancer, unexplained weight loss, or age over 50 years should be evaluated for malignancy risk 1, 2
Infection indicators such as fever, recent bacterial infection, or immunosuppression should be assessed in patients with back pain 2, 3
Fracture risk should be evaluated in patients with age over 70 years, significant trauma, or prolonged corticosteroid use 2, 4

The American College of Physicians recommends performing a targeted examination to identify radiculopathy or spinal stenosis, including straight-leg raise test, crossed straight-leg raise, motor strength testing, reflex examination, and sensory distribution assessment 6
The straight-leg raise test has a sensitivity of 91% and specificity of 26% for herniated disc 6

The American College of Physicians recommends assessing psychosocial factors such as depression, anxiety, passive coping strategies, and job dissatisfaction to predict chronicity and delayed recovery in patients with back pain 6, 2
The STarT Back tool can be used to risk-stratify patients into low, medium, or high-risk categories for developing chronic disability 3

The American College of Physicians recommends against routine imaging for nonspecific low back pain without red flags 1, 6, 5
Imaging is indicated in specific scenarios such as severe or progressive neurologic deficits, suspected cauda equina syndrome, history of cancer, or constitutional symptoms suggesting infection or malignancy 1, 5, 2, 3

The American College of Physicians recommends lowering the threshold for imaging and earlier reassessment in elderly patients (>65-70 years) due to higher prevalence of serious pathology and increased risk of undertreatment 6, 4, 2

The American College of Physicians recommends reevaluating patients with persistent, unimproved symptoms after 1 month, with earlier or more frequent reevaluation warranted for severe pain, functional deficits, or signs of radiculopathy or spinal stenosis 1, 6, 4

The American College of Physicians recommends modifying assessment and medication approach in patients with CKD, including using acetaminophen as first-line analgesic and avoiding NSAIDs or using with extreme caution if GFR <45 4

The American College of Physicians recommends categorizing patients into one of four groups to guide management: nonspecific low back pain, back pain with radiculopathy or spinal stenosis, back pain from nonspinal source, or back pain with specific spinal cause 6, 2, 3
