Brief Summary

This is a cluster randomized controlled trial to to evaluate the individual and health system impacts of implementing a new physiotherapist-led primary care model for back pain in Canada.

Conditions

Back Pain, Low

Outcome Measures

Primary Outcomes (1)

• Self-reported Disability

  Measured using the Roland Morris Disability Questionnaire (0 to 24 with higher scores indicating greater disability)

Secondary Outcomes (24)

• Self-reported Pain Intensity

  Change from baseline at 6-week, 12-week, 6-month, 9-month, and 12-month follow-ups

• Pain Self Efficacy

  Change from baseline at 6-week, 12-week, 6-month, 9-month, and 12-month follow-ups

• Health Related Quality of Life

  Change from baseline at 6-week, 12-week, 6-month, 9-month, and 12-month follow-ups

• Global Rating of Change

  Change from baseline at 6-week, 12-week, 6-month, 9-month, and 12-month follow-ups

• Satisfaction with Health Care

  6-week, 12-week, 6-month, 9-month, and 12-month follow-ups

Other Outcomes (4)

• Comorbidities

Physiotherapist-led primary care model for back pain

EXPERIMENTAL

The index intervention will incorporate a PT within the primary care team and make them available at the first point of contact for people with low back pain. There will be 4 key components of this intervention: 1) Initial assessment and screening; 2) Brief individualized intervention at first visit; 3) Health services navigation; 4) Providing additional PT care for people with an unmet need (e.g., no insurance coverage for PT).

Behavioral: Physiotherapist-led primary care model for back pain

Usual care

ACTIVE COMPARATOR

The physician-led primary care intervention will be unstandardized to best reflect standard clinical practice in Canada. This usually includes a visit to a primary care physician, who would perform a history and physical examination, provide LBP education, order diagnostic imaging, prescribe medications and/or refer based on their assessment findings and patient preferences.

Behavioral: Usual care

Interventions

Physiotherapist-led primary care model for back pain BEHAVIORAL

Assessment and screening: taking a history; screening for red flags, comorbidities, and risk factors of ongoing pain and disability; physical examination. Brief individualized intervention at the first visit: effective communication, cognitive reassurance, a few exercises, and advice/strategies to stay active. Health services navigation: PT assistance with navigating healthcare services based on the assessment findings. First, red-flags requiring emergency or urgent referrals. Next, comorbid conditions that would benefit from care from other healthcare providers. Finally, referral to PT (if appropriate). Providing additional physiotherapy care to people with an unmet need: Additional physiotherapy care will be provided to patients who have an identified need for physiotherapy but no physiotherapy coverage through private or government health insurance plans.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Masking Details: Due to the nature of the new model of care and comparison, it is not possible to blind the patients or health care providers. Since the primary outcomes are self-reported outcome measures, the assessor is also not blind to the intervention.
• Purpose: TREATMENT
• Intervention Model: PARALLEL
• Sponsor Type: OTHER

• PI Title: Assistant Professor, School of Rehabilitation Therapy, Queen's University

Model Details: This is a cluster randomized controlled trial randomizing 20 sites to the PT-led primary care model for back pain or to the usual care model
