Undertreated Severe Chronic Pain – Risks | Dr. James Schaller, MD

Assessment, Mitigation, and Practice Essentials

Clinic-ready checklist and guidance

---

• Rapid risk recognition — red flags of undertreatment – Escalating pain despite adherence; functional decline; fragmented sleep; mood deterioration or passive death wishes; unsanctioned analgesic use; ED visits for pain. References: Woolf CJ. Pain. 2011;152(3 Suppl):S2-S15. Racine M. Prog Neuropsychopharmacol Biol Psychiatry. 2018;87(Pt B):269-280.
  
• Multidimensional reassessment at every visit – Pain qualities; function (sit–stand–walk, ADLs); sleep; mood (PHQ‑9/GAD‑7); substance risk; goals of care. Reference: Institute of Medicine (US). Relieving Pain in America. 2011.
  
• Treat the dominant mechanisms – Nociceptive: scheduled non‑opioids, targeted procedures. Neuropathic: SNRIs, TCAs, gabapentinoids, topical agents. Nociplastic/central: education, exercise therapy, CBT, sleep restoration. References: Woolf CJ. Pain. 2011;152(3 Suppl):S2‑S15. Dueñas M. Pain Physician. 2016;19(4):E333‑E346.
  
• Address sleep early (pain–sleep vicious cycle) – Sleep hygiene, CBT‑I, circadian regularity; cautious hypnotic use; evaluate/treat OSA. Reference: Finan PH, Goodin BR, Smith MT. Sleep Med Rev. 2013;17(3):211‑222.
  
• Aggressively manage comorbid depression/anxiety – SNRIs/TCAs, psychotherapy, physical activation; collaborative behavioral health. Reference: Bair MJ, et al. Arch Intern Med. 2003;163:2433‑2445.
  
• Functional restoration focus – Graded activity, pacing, PT/OT, fear‑avoidance reversal; work‑focused rehab when applicable. Reference: Dueñas M. Pain Physician. 2016;19(4):E333‑E346.
  
• Risk‑balanced analgesia – Optimize non‑opioid/interventional options; if opioids, define functional goals, use lowest effective dose, monitor benefits/harms, deprescribe if goals unmet. Reference: Turk DC, Swanson KS, Gatchel RJ. Clin J Pain. 2008;24(6):497‑508.
  
• Special populations – Older adults: fall mitigation, renal/hepatic dosing, polypharmacy review. Pregnancy/postpartum: non‑pharmacologic first‑line, coordinate OB/anesthesia. Pediatrics: family‑centered, school liaison, minimize sedating meds. References: Stubbs B. Arch Phys Med Rehabil. 2014;95:175‑187. Eccleston C. Lancet Child Adolesc Health. 2021;5:665‑675. Wang Y. J Affect Disord. 2020;263:413‑420.
  
• Prevent social harm and isolation – Structured social engagement; caregiver education and support; screen caregiver strain. Reference: Dueñas M. Pain Physician. 2016;19(4):E333‑E346.
