International Consensus
Recommendations for
Acute Low Back Pain (ALBP)
The Delphi consensus process for International Recommendations on Acute Low Back Pain (ALBP) Management involved 48 responses across 3 rounds from 30 unique experts in 14 countries. The Group Discussion, which synthesized the consensus, involved 26 experts total (24 from Round 3 individual respondents plus 2 additional contributors).
The process demonstrated strong convergence toward consensus, with mean ratings improving from 3.20/5.00 in Round 1 to 4.41/5.00 in Round 3 among individual respondents. All seven topic areas achieved strong positive trends, with consensus strengthening substantially from Round 1 to Round 3. The final group consensus of 4.28/5.00 validates 10 key recommendations for evidence-based ALBP management.

Critical Insights from the Delphi Process
1. General Key Messages (Q1–Q14): Strongest Overall Consensus
Round 3 mean of 4.51/5 (90.5% positive). Group consensus achieved highest rating at 4.79/5 (92.9% positive). Experts strongly agree on foundational principles.
2. Assessment & Imaging (Q15–Q21): Individual vs. Group Divergence
Round 3 individuals strongly supportive (4.20/5, 75% positive) but Group consensus more cautious (3.14/5, 14.3% positive), reflecting legitimate debate about specific imaging approaches.
3. Red Flags / Imaging Criteria (Q22–Q26): Strong Expert Consensus
Strong expert consensus (4.55/5 in R3, 4.60/5 in Group, 80–85% positive). Clear agreement on clinical warning signs requiring imaging.
4. Self-Management — Rec. 1 (Q27–Q34): Unanimous Support
Excellent consensus with highest mean rating in Group (5.00/5, 100% positive). Unanimous expert support for first-line self-care approach.
5. If Not Improving — Rec. 2a (Q35–Q43): Strong Convergence
Strong convergence from 2.67 (R1) to 4.38 (R3 individuals). 83.3% positive in Round 3. Clear support for escalated non-pharmacological interventions.
6. Radiculopathy-Specific — Rec. 2b (Q44–Q49): Most Contentious Area
Round 3 individuals achieved 50% positive (3.80/5) but Group consensus only 0% positive (3.00/5). Reflects ongoing clinical debate about steroid efficacy.
7. Opioids — Rec. 3 (Q50–Q58): Strong Safety Consensus
Strong expert consensus against opioid first-line use. Round 3: 88.4% positive (4.56/5). Group: 66.7% positive (4.33/5). Clear safety message across all rounds.
The 10 International Consensus Recommendations
Patient Engagement & Shared Decision-Making
Physicians should acknowledge and validate the patient's pain. Patient education is critical. Shared decisions with patients are essential and foundational for all care pathways.
Self-Care — Start Immediately
Stay active, stretch, and maintain range of motion. Apply heat, optimize anti-inflammatory medications, maintain daily activity, and avoid bed rest. Optimize nutrition, sleep hygiene, and hydration. Inactivity can slow recovery. Non-pharmacological options should be prioritised as first-line management.
Consider Additional Modalities If Not Improving
Spinal manipulation, acupuncture, optimised NSAIDs, and muscle relaxants may be appropriate. Multiple non-drug options should be prioritised; improvement measured by outcomes.
Initiate Further Evaluation If Not Improving
Clear escalation pathway. Seek care if symptoms worsen or persist. Rule out underlying pathology and adjust management based on evaluation findings.
Acute Radiculopathy — Local Steroid Injections
Evidence supports LOCAL epidural steroid injections for acute radiculopathy. Insufficient evidence for systemic steroids. Steroids only for radiculopathy — temporary relief, short durations only.
Red Flags — Warrant Immediate Evaluation
Red flags (bowel/bladder dysfunction, new or progressive numbness or weakness) warrant immediate evaluation. Clinical history indicating risk of cancer, infection, or fracture also requires prompt assessment and should be evaluated separately from red flag symptoms.
Imaging — Only With Red Flag or High-Risk History
Imaging is warranted only with a red flag, history of cancer, or clinical suspicion of infection or fracture. Avoid routine imaging in uncomplicated ALBP — it does not improve outcomes and adds unnecessary cost and anxiety.
Opioids — Not First-Line Therapy
Avoid as first-line treatment. Try non-opioid treatments first. Generally ineffective for function. Unnecessary early use should be avoided.
Opioid Safety & Patient Counseling
If used: short-acting, time-limited, strict monitoring, regular reassessment. Counsel on safe use, side effects, and risk of dependence from long-term use. Avoid when safer alternatives are effective.
Multimodal Approach to Management
Psychosocial factors influence recovery. Escalate only when clinically appropriate. Combine physical, psychological, and pharmacological interventions — tailored to the individual.
