IntroductionBurns of the face and mouth region have a profound impact on function. Currently the outcome measure that is most commonly used in the burn care literature is horizontal and vertical opening. Impairment-based outcomes such as this do not capture the functional implications of these injuries in spite of the devastating impact they can have on burn survivor's lives.Purpose Of The StudyTo generate an assessment that evaluates the impairments, activity limitations, and participation restrictions associated with mouth injuries and prospectively collect data to examine the clinimetric properties.MethodsA multistep assessment development process was undertaken including a comprehensive literature search and review, burn care expert and burn survivor interviews, generation of a preliminary version and field-testing, modifications based on field testing and updated literature review, and further field testing with data collection of 23 burn survivors. Clinimetric properties were examined by evaluating: whether there was a ceiling or floor effect, the internal consistency, construct validity, and responsiveness.ResultsThe mouth impairment and disability assessment (MIDA) has a 28 item self-report portion, divided into four subscales, completed by the patient and an impairment-based section completed by the burn therapist. Two items demonstrated a ceiling effect, one was removed the other retained. There was strong and statistically significant (p<0.0001) correlation of the symptoms subscale as well as vertical opening with the functional activities subscale of the MIDA. The functional activities subscale demonstrated good internal consistency and the symptoms subscale was adequate. Re-evaluation approximately seven and a half months after the baseline evaluation demonstrated a statistically significant change with time and treatment.ConclusionsThe MIDA now offers clinicians the ability to assess mouth impairment and disability of burn survivors who have sustained burn injuries to their face and mouth region.Copyright © 2017 Elsevier Ltd and ISBI.
