Improving Access and Care Quality for Temporomandibular Disorder Patients - a Prospective Study to Examine Diagnostic Concordance Between Advanced-practice Physical Therapist and Oral and Maxillofacial Surgeon
Improving Access and Care Quality for Temporomandibular Disorder Patients - a Prospective Study to Examine Diagnostic Concordance Between Advanced-practice Physical Therapist and Oral and Maxillofacial Surgeon
Jaw disorders is the leading cause in facial pain, affecting many people in the world. Despite many patients finding relief from conservative treatment, many get referred to the surgeon for an evaluation. In order to improve access to care and reduce wait times, a new advanced practice physiotherapist-led triage model is being studied.
Temporomandibular disorders (TMD), involving the temporomandibular joint and masticatory muscles, are the leading cause of orofacial pain, affecting approximately 5-12% of the global population and generating an estimated $4 billion in annual healthcare costs. While 50-90% of individuals experience symptom relief through non-surgical interventions, fewer than 10% ultimately require surgical treatment. For patients who do not respond to conservative management, referral to a medical specialist is typically necessary to guide further care. In Canada, however, high demand for specialized services results in prolonged wait times. At the McGill Oral and Maxillofacial Surgery (OMFS) Division, patients can wait more than six months for an initial consultation and over a year for a surgical procedure. When accounting for additional delays related to diagnostic imaging and prior referrals, total wait times may exceed two years. These delays can have deleterious consequences, including worsening pain, increased functional disability, and a significant decline in quality of life for patients awaiting timely interventions. Above all, in the absence of a structured triage process, many patients are prematurely referred to surgical services, often before exhausting appropriate non-surgical options. This contributes to unnecessary delays in care, increased healthcare costs, and excessive demand on already overburdened speciality clinics.
The implementation of innovative care models led by advanced practice physiotherapists (APPTs) offers a promising solution. APPTs are highly trained health professionals with advanced competencies in musculoskeletal assessment, differential diagnosis, and evidence-based management, with the ability, depending on regulated scope of practice, to independently recommend investigations, initiate treatment plans, and make referrals when necessary. Advanced practice physiotherapy (APPT) models of care have been successfully deployed in various specialized care settings-such as orthopaedics, neurosurgery and rheumatology, where they have improved patient flow, reduced wait times, and maintained or improved patients' clinical outcomes. In these contexts, APPTs function as a first-contact autonomous practitioners, managing a substantial proportion of MSKD cases that would otherwise be directed to physicians or surgeons.
By integrating APPTs into the triage pathway for TMJ referrals, patients could be more effectively directed toward appropriate non-surgical care, such as physiotherapy, education, and self-management strategies, when surgical intervention is not warranted. This approach would help preserve the Oral and Maxillofacial Surgery department resources for patients with conditions that truly require surgical expertise. While APPT models have been successfully implemented and evaluated in various musculoskeletal care settings, no studies to date have described or assessed the implementation of such a model specifically for the management and triage of TMDs. This represents a significant gap in the literature and an important opportunity to explore the potential benefits of APPT-led care in improving access and efficiency in specialized orofacial pain services.
