Musculoskeletal disorders (MSKDs) are a leading cause of global disability, pain and work disability. Even if they are not fatal, they are disabling and their care places a significant burden on the healthcare system. Knowing that early intervention improves clinical outcomes, the healthcare system must ensure that those affected have access to the care they need, which is currently not the case. Optimizing the use of resources through the development of innovative and effective interventions must therefore be addressed. In randomized controlled trials (RCTs) conducted by our team, we have demonstrated that not all patients with MSKDs need to be closely followed by a health professional as for a large proportion of patients simply educating them is enough to resolve their MSKD. As healthcare costs escalate, using a Stepped Care Model in which patient education is offered first, providing usual care only to those whose symptoms have not resolved might lead to more efficient healthcare use and lower costs. The primary objective of this RCT is to establish the effectiveness of a new model of care for MSKDs by comparing a Stepped Care Model to the two most widely used models of care: Usual Medical Care and Usual Rehabilitation Care. A secondary objective will be to compare the costs associated with each of these care models. We hypothesize that a Stepped Care Model will be as effective as Usual Medical and Rehabilitation Care to reduce functional limitations, but will lead to lower costs.
In this pragmatic parallel-group RCT, 369 adults presenting a MSKDs will be randomly assigned to one of the intervention groups: 1) Stepped Care, 2) Usual Medical Care (physician-led intervention \[up to 3 appointments within 12 weeks\]: e.g., advice/education, pharmacological pain management), 3) Usual Rehabilitation Care (physiotherapist-led intervention \[up to 10 appointments within 12 weeks\]: e.g., advice/education, exercises). During the first 6 weeks of the study, participants in the Stepped Care Group will take part in a self-management education program that includes two education sessions with a physiotherapist; after 6 weeks, those still experiencing clinically important symptoms will receive follow-up rehabilitation interventions (up to 5 sessions within 6 weeks), while those not experiencing clinically important symptoms will be considered recovered and will have no further intervention. The primary (functional limitations) and secondary outcomes (e.g., pain severity, health-related quality of life, pain-related fear, pain self-efficacy), assessed at baseline and at 6, 12 and 24 weeks, will be compared between the groups using repeated measures analyses (linear mixed models). Costs estimate from the public payer and patient perspective will be established (including incremental cost-effectiveness and cost-utility ratios) and compare between care models (one-way ANOVA). Our research team has all the expertise (health services organization, medicine, rehabilitation, biostatistics, health economics) necessary to carry out this project. Knowing the urgent need for an overhaul of services to reduce wait times and ensure equitable access, the Stepped Care Model proposed could be a solution to improve access to health services without compromising quality of care. If the results are conclusive, they would lay the foundation for a future pan-Canadian trial examining the benefits of implementing such a model into the public healthcare system.
