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.
This study aims to evaluate the individual health outcomes and health system impacts of implementing a new physiotherapist-led primary care model for people with low back pain (LBP).
The overarching goal of this study is to determine the impact of integrating a physiotherapist (PT) within primary care teams for people with LBP and making them available to patients as the first point of contact. The specific aims of the research are to determine:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 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). |
|
| 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. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| 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. |

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.

| Depressive Symptoms | Measured using the 2-item Patient Health Questionnaire (PHQ-2) (0 to 6 with greater scores indicating increased depressive symptoms). This measure was changed from the PHQ-9 to PHQ-2 after initial trial registration but prior to initiating patient recruitment reduce response burden. | Change from baseline at 6-week, 12-week, 6-month, 9-month, and 12-month follow-ups |
