Brief Summary

Acute low back pain, the second leading cause of medical consultations in France, poses a major public health challenge, particularly because of its high risk of progressing to chronic low back pain-the leading cause worldwide of years lived with disability. Pharmacological treatments such as paracetamol, opioids, non-steroidal anti-inflammatory drugs (NSAIDs) and muscle relaxants show limited benefit in terms of pain intensity or functional disability. Non-pharmacological treatments, including exercise therapy and psychological support, show promising results but remain hampered by methodological biases and small sample sizes. A biopsychosocial approach that combines pharmacological treatments, physical therapy, psychological support and social interventions has demonstrated moderate improvements in pain and function for chronic low back pain but remains insufficiently studied for acute presentations. French guidelines advocate a combined strategy involving paracetamol, NSAIDs, physical activity and psychosocial risk assessment. However, a French multicentre retrospective study highlighted marked heterogeneity in clinical practice, along with a low adoption rate (\<10 %) of these recommendations in emergency departments, underscoring the need to strengthen adherence to evidence-based management strategies. We hypothesise that a multimodal intervention targeting physicians (guideline reminders) and patients (information on disease progression and multidisciplinary care plans), to enable the systematic implementation of all aspects of a biopsychosocial approach in emergency departments, could reduce short-term pain and disability in patients with acute low back pain.

Outcome Measures

Primary Outcomes (1)

  • Pain Interference Score at 7 days

    Pain interference score at 7 days, assessed using the Pain Interference subscale of the Brief Pain Inventory - Short Form (BPI-SF). The score is calculated as the mean of 7 items (each rated 0-10) and reported on a 0-100 scale

    7 days

Secondary Outcomes (7)

  • Pain intensity at 7 days, measured by the BPI SF intensity score.

    7 days

  • Number of pain-free days after the emergency department visit

    7 days

  • Total amount of opioids consumed

    7 days and 3 months

  • Number of days off work

    7 days and 3 months.

  • Functional disability

    3 months

  • +2 more secondary outcomes

Study Arms (2)

Control group

NO INTERVENTION

Usual care - Standard care for acute non-specific low back pain at clinician's discretion

Intervention group

EXPERIMENTAL

Biopsychosocial approach

Other: Biopsychosocial intervention

Interventions

The biopsychosocial intervention consists of a structured program implemented in participating emergency departments. It includes a standardized 3-hour online training session for physicians covering evidence-based management of acute low back pain, rational pharmacological use, promotion of physical activity, and consideration of psychosocial factors. A summary sheet will be given with key recommendations during the period. For patients, short educational materials provide information on typical recovery, self-management strategies, and appropriate follow-up. The intervention is introduced sequentially across 12 centers according to a stepped-wedge randomization schedule, with each site moving from control to intervention while maintaining standard emergency care.
