Hip Osteoarthritis, Knee Osteoarthritis
Conditions
Brief summary
This is a pilot cluster randomized controlled trial to to evaluate the individual and health system impacts of implementing a new physiotherapist-led primary care model for hip and knee pain in Canada.
Detailed description
Arthritis is one of the leading causes of pain, disability, and reduced quality of life in patients. Arthritis currently affects one in five Canadians (six million), which is expected to rise to nine million people by 2040. Osteoarthritis (OA) is the most common forms of arthritis, with hip and knee being two of the most common locations. For most people, the first point of contact for their pain is their primary care provider. Due to the rise in patients seeking support at the primary care level, the shortage of primary care providers, and the high burden on these providers, patients often do not receive timely access to the care they require. A promising strategy is to have an integrated model of care where a physiotherapist (PT) is the first point of contact within interprofessional primary care teams. PTs can provide a comprehensive and efficient management strategy for patients presenting to their primary care provider with hip and knee pain complaints. This study aims to determine the feasibility of conducting a cluster randomized trial in primary care settings in Ontario to evaluate the individual health outcomes and health system impact of implementing a new physiotherapist-led primary care model for people with hip and knee pain. The primary objectives of this pilot study are: 1. Determine the feasibility of participant recruitment, assessment procedures, and retention. 2. Determine the feasibility of implementing a new PT led primary care model for hip and knee pain. 3. Explore the perspectives of patient participants and HCPs related to their experiences and attitudes towards the new service delivery model, barriers/facilitators to implementation, perceived satisfaction, perceived value and impact on clinic processes and patient participant outcomes.
Interventions
1. Initial assessment and screening: The PT will provide a comprehensive assessment according to established clinical practice guidelines. 2. Brief individualized intervention at first visit: The PT intervention will be at the discretion of the PT to reflect real-world PT intervention. 3. Health services navigation: Participants will be provided with options available to them in their community for rehabilitation. For example, they may be referred to community PT for ongoing management or presented with group exercise options. Participants will be assessed regarding the need for specialist referrals or resources available to manage complex clinical presentations such as comorbidity or frailty. Participants may be referred to the primary care provider if no specialized services are needed or when the PT cannot provide a direct referral. All individuals may have their medications reviewed by a physician if deemed appropriate by the PT or requested by the participant.
The physician led primary care intervention will be unstandardized to best reflect standard clinical practice in Canada.

Masking description
Due to the nature of the new model of care and comparison, it is not possible to blind the patient participants or health care providers. Since the primary outcomes are self-reported outcome measures, the assessor is also not blind to the intervention.
Intervention model description
This is a pilot cluster randomized controlled trial randomizing 14 sites to the PT-led primary care model for hip/knee pain or to the usual care model

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Participant Recruitment Rate | 20 weeks | A full trial will be feasible if the investigators are able to recruit 1.5 participants per week per site over 20 weeks |
| PT Treatment Fidelity | 20 weeks | Treatment fidelity will be measured through an audit of a PT fidelity checklist and electronic medical record (EMR) to determine the consistency of the care provided. An acceptable level of fidelity will be considered ≥80% for each intervention component. |
| Retention | 12 months | The investigators consider an attrition rate of ≤20% at 12-month follow-up successful. ≤35% attrition will be considered partially successful; however, additional retention strategies would be required for the full trial based on evidence that ≥20% attrition threatens trial validity |
| Assessment Procedures | 12 months | The investigators consider ≥80% of all assessment items completed and a mean time for completion of ≤60 minutes acceptable. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Health-Related Quality of Life | Baseline and 3, 6, 9, and 12 months follow-up | Measured using the EuroQoL-5D-5L (0 to 100 with greater scores indicating greater self-reported health related quality of life) |
| Pain Self Efficacy | Baseline and 3, 6, 9, and 12 months follow-up | Confidence in abilities to participate in usual activities using the Pain Self Efficacy Questionnaire |
| Catastrophic Thinking | Baseline and 3, 6, 9, and 12 months follow-up | Measured using the Pain Catastrophizing Scale (0 to 52 with higher scores indicating greater catastrophic thinking) |
| Fear of Movement | Baseline and 3, 6, 9, and 12 months follow-up | Measured using the Tampa Scale of Kinesiophobia (an 11-item questionnaire) |
| Depression Subscale | Baseline and 3, 6, 9, and 12 months follow-up | Measured using the 2-Item Patient Health Questionnaire |

| Satisfaction with Health Care | 3, 6, 9, and 12 months follow-up | Measured using an 11-point scale(-5 to +5 with negative scores indicating a dissatisfaction with health care received and positive scores indicating satisfaction with health care received) |
