Low back pain management
Prospective diagnostic concordance studies
In a secondary analysis of RCT comparing diagnostic & management decisions Janny Mathieu et al. from:
- Université du Québec à Trois‑Rivières, Trois‑Rivières, QC, Canada
- CIUSSS‑MCQ, Trois‑Rivières, QC, Canada
- Division of Neurosurgery, Faculty of Medecine, Université de Montréal, Montréal, QC, Canada.
- Université de Sherbrooke, Longueuil, QC, Canada
- Balgrist University Hospital, Zurich, Switzerland
- University of Zurich Spine Centre, Zurich, Switzerland
- University of Toronto, Toronto, Canada
published in Scientific Reports to assess agreement in diagnosis and management between chiropractors and neurosurgeons for patients referred for Low back pain consultation. Diagnostic concordance was moderate (74.7%, κ = 0.51), management concordance strong (82%), suggesting chiropractors are competent for triage of non‑surgical low back pain, potentially easing surgical consult load 1)
Critical review:
- Strengths:
- Real‑world, clinically relevant sample (mean age ~60, N=101).
- Direct comparison with neurosurgeons using standardized categories.
- Good statistical rigour with κ, CI, p‑values reported.
- Limitations:
- Secondary RCT analysis; original trial focused on triage communication, not concordance.
- Moderate κ value indicates appreciable diagnostic disagreement.
- Setting: tertiary spine clinic—referral bias and limited generalizability to primary care.
- Chiropractors less often labeled non‑specific LBP (31.6% vs neurosurgeons 43.2%, p = 0.02), which may reflect over‑triage or differing diagnostic threshold
- Blinding unclear; could influence neurosurgeon assessments.
- No clinical outcomes or patients’ care trajectory data presented here.
Final verdict (score: 6/10)
This well‑performed concordance study supports the potential role of chiropractors in neurosurgery triage pathways. However, moderate diagnostic agreement and tertiary clinic setting limits full endorsement. More prospective trials linking triage accuracy to patient‑centered outcomes are needed.
Takeaway for neurosurgeons: Chiropractors demonstrate acceptable diagnostic and strong management alignment with neurosurgeons. They may effectively triage non‑surgical low back pain, helping reduce surgical wait times—but diagnostic nuance remains essential.
Bottom line: Chiropractor‑based triage shows promise for improving low back pain pathways, yet definitive benefit requires prospective validation with patient outcomes.
