Exploring Trismus Management in Australia: A Mixed Methods Evaluation of Surveys and Interviews With Health Professionals.

Objective: This study evaluates how health care professionals manage trismus in Australia and identifies facilitators and barriers experienced by clinicians in routine patient care.

Methods: A mixed-methods approach was used to evaluate the experience of clinicians. Medical, nursing, and allied health practitioners in Australia were invited to participate if they had treated patients with trismus in the last 5 years. Participants completed an investigator-designed survey and were invited to participate in a semi-structured audio-recorded interview to explore practice in more depth. Quantitative data were analyzed using descriptive statistics and qualitative data were analyzed thematically using an inductive, data-driven approach.

Results: Fifty-six clinicians (38 speech pathologists, 9 physiotherapists, 7 medical doctors, 1 nurse, and 1 osteopath) completed the survey, 12 of which also participated in an interview. The most common assessment tool was a commercially available measurement tool (Therabite or Orastretch), the most common treatment approach was stacked tongue depressors, and the most common exercise regimen was a 30- s stretch 25 times per day. Common barriers to trismus management included the high cost of devices, lack of clinical experience, and lack of training opportunities outside their institution. Clinician-perceived facilitators were different modes of information provision and time to consider the exercise instructions and rationale. Several clinicians relied on telehealth to reach patients in remote locations and improve efficiency.

Conclusion: A range of clinicians treat trismus arising from a variety of conditions. Training opportunities are critical for clinicians to develop and extend their skills in assessing and treating trismus.

Impact statement: The morbidity associated with trismus, and the absence of a clinical guideline or consensus document warrants careful consideration as to the translation of evidence into the clinical context.
