A COnsensus-based Standards for the selection of health Measurement INstruments systematic review of orthognathic patient-reported outcome measures

Introduction: This systematic review aimed to identify and appraise the validity studies of patient-reported outcome measures (PROMs) reporting the outcomes of combined orthodontic-orthognathic surgery in treating dentofacial deformity. Methods: The search strategy was conducted using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Systematic Review methodology. The following databases were searched for original studies outlining the development and/or validation of PROMs produced to measure the outcomes of combined orthognathic-orthodontic treatment: EMBASE, MEDLINE, PsycInfo and Scopus. Publications were limited to the English language. Eligibility criteria were applied when considering the studies. Primarily, the psychometric properties and quality of orthognathicspecific PROMs were investigated. Screening of eligible studies was conducted independently by 2 reviewers. Assessment of the methodological quality of the studies and data extraction was conducted by 1 reviewer and assisted by a second reviewer. The COSMIN methodology guided data extraction and analysis, which were divided into 3 stages-a synopsis of studies, evaluation of methodological quality, and summary of evidence. Results: A total of 8695 papers were found; 12 studies met the criteria for inclusion. Regarding the COSMIN Checklist for Assessing Study Qualities, there was evidence that the Orthognathic Quality of Life Questionnaire was the most extensively tested orthognathic-specific PROM in the current literature. The reported evidence was incomplete, as not all psychometric properties had been reliably tested. Conclusions: Clinicians must use validated PROMs when analyzing patient-reported outcomes. The Orthognathic Quality of Life Questionnaire was shown to be the highest quality orthognathic-specific PROM in the literature but requires contemporary evaluation to suitably reflect the COSMIN guidance.
