Fear-Avoidance and Opioid Escalation in Chronic Low Back Pain
A 45-year-old man has a 3-year history of chronic low back pain after a lifting injury. Pain is 8/10; he takes oxycodone 10 mg every 6 hours (60 MME/day) and cyclobenzaprine 10 mg at night. He stopped physical therapy after two sessions because "the pain got worse." He believes "my spine is crumbling," walks with a cane despite unremarkable imaging, and sleeps 4 hours nightly. PHQ-9 is 14, GAD-7 is 12, and he scores high on pain catastrophizing. Examination shows no red flags. He is on short-term disability and asks for an oxycodone increase to 20 mg every 6 hours.
1. Distinguish red flags from yellow flags and explain how the psychosocial findings change your management.

There are no red flags: no bowel or bladder dysfunction, saddle anesthesia, fever, cancer history, significant trauma, or progressive neurological deficit. The dominant findings are yellow flags-catastrophizing, fear-avoidance, distress, sleep disruption, and disability-which predict poor response to opioid escalation and better response to biopsychosocial rehabilitation. His request for more opioid should be reframed as a request for relief. I would validate his distress, explain that imaging does not show a crumbling spine, and state that increasing the opioid dose is not the first-line treatment. This changes management from medication escalation to functional rehabilitation.
2. Design a rehabilitation and behavioral plan, including sequencing and how you would address his request for more opioid.

Do not increase the opioid. Continue the current dose initially to avoid withdrawal, then plan a slow taper, such as 10% per month, once behavioral treatment is established, with a more rapid taper if misuse emerges. Refer to pain psychology for CBT and graded exposure. Physical therapy should use graded activity, not bed rest; start with short walks and avoid fear-based stopping. Treat depression and anxiety with psychotherapy and/or an SSRI, and address sleep with sleep hygiene and CBT-I. Cyclobenzaprine can worsen sedation; consider stopping it. Set functional goals and explain the sequence clearly.
3. What outcomes would you track to determine whether the plan is working?

Track pain interference and function, such as PROMIS pain interference, walking tolerance, and work status; sleep hours; PHQ-9; GAD-7; pain catastrophizing; opioid use; and misuse behaviors. Success is improved function and quality of life with a stable or lower opioid dose, not just a lower pain score. Reassess every 4–6 weeks and coordinate with physical therapy and psychology. If function does not improve or misuse appears, revisit the diagnosis and treatment plan rather than simply increasing analgesia.
