Systematic reviews (SRs) on the management of temporomandibular disorders (TMDs) have predominantly focused on evaluating the effectiveness of various treatments, identifying those that provide the greatest benefits. However, the economic evaluation of these treatments has not been systematically explored. This SR aims to address this gap by evaluating the economic outcomes of the most common treatment modalities for TMDs, including cost-effectiveness, cost-utility, cost-benefit, cost-minimisation and the burden of illness.

This SR will be conducted using the following electronic databases Business Source Complete, CINAHL, EconLit (ProQuest), Embase (Ovid), MEDLINE (PubMed), MEDLINE (Ovid) and Scopus to identify studies evaluating the economic outcomes of treatments for TMDs. The eligibility criteria are as follows: (1) studies examining the costs and/or impact of treatments for TMDs and (2) articles published between 2000 and 2025. The primary outcomes of interest are the economic findings outlined earlier. Data extraction will include the following: author(s), year of publication, country, study objectives, study design, eligibility criteria, TMD diagnosis and screening, study groups, randomisation, blinding, sample size, number of participants invited, enrolled and completed, duration of treatment, follow-up, study duration, settings, assessment instruments, study outcomes, statistical analyses, results, limitations, strengths and funding sources. The quality of studies will be evaluated using the Consolidated Health Economic Evaluation Reporting Standards 2022 checklist, with risk of bias assessed using the Cochrane Effective Practice and Organization of Care’s risk-of-bias tool; where applicable, the Outcome Reporting Bias in Trials will be used to detect reporting biases. A narrative synthesis and summary tables will outline study characteristics, economic outcomes and the overall quality of evidence. We will conduct qualitative secondary and sensitivity analyses.

This SR does not require an ethics approval. The results will be disseminated through international and national conferences and peer-reviewed journals.

Brain and heart conditions are among the leading causes of illness and mortality in Canada. Heart failure is one of the fastest-growing cardiovascular conditions globally, with more than 100 000 Canadians diagnosed each year. Individuals with heart failure are at significantly increased risk of mental health challenges such as depression, anxiety and stress. However, healthcare services often remain siloed, treating physical and mental health separately. This complicates care for individuals with multiple chronic conditions. This multiyear study will adapt, test and accelerate changes to regional care delivery models in Eastern Ontario to optimise brain-heart health and generate knowledge to support the spread and scale of effective interventions that address community needs and priorities. We aim to: (1) identify resource gaps by mapping available services; (2) document strengths and challenges in care delivery; and (3) co-design, pilot test and evaluate an intervention developed based on the priority gap area(s) identified through objectives (1) and (2).

This community-based participatory action research study is led by a research coalition of patient and caregiver partners, care providers and leadership staff from two Ontario Health Teams. In Year 1, we will conduct asset mapping and community consultations with individuals living with heart failure, caregivers, care providers and service organisations to identify care gaps, strengths and opportunities for improvement around modifiable behavioural risk factors and brain-heart health. A scoping review will identify evidence-based strategies to address care gaps and inform the co-design of an intervention focused on supporting individuals with brain-heart interconnected conditions. In Year 2, we will co-design an intervention with community partners for implementation with clinical test sites. Year 3 will involve pilot testing the intervention and conducting outcome and process evaluations. This will inform future spread and scale of the intervention to other brain-heart conditions and new jurisdictions.

The study is approved by the Bruyère Health Research Ethics Board (M16-24-016). Findings will be disseminated through peer-reviewed publications, conference presentations and knowledge mobilisation activities such as social media, community events and local media outreach, as well as through dedicated engagement with Ontario Health partners and the Brain-Heart Interconnectome Network via retreats and collaborative forums.
