Development of a novel patient-reported outcome measure for orthognathic surgery.

OBJECTIVES

This study aimed to develop a new patient-reported outcome measure (PROM) to systematically and scientifically evaluate patients' subjective feelings after orthognathic surgery.

METHODS

A literature review and semi-structured interviews were conducted to construct a conceptual framework and an item pool, followed by expert and patient surveys for measure construction. We conducted a clinical investigation to test the feasibility, reliability, and content validity of this measure.

RESULTS

The conceptual framework included four domains: psychological health, physiological health, social function, and satisfaction, and 33 items were included in the survey. Following the expert analysis, 31 items remained in the draft. The clinical investigation showed a 100% recovery and completion rate and good reliability, with Cronman-Brown formula coefficients of 0.893 and 0.944, respectively.

CONCLUSIONS

A new outcome measure to evaluate patients' subjective feelings after orthognathic surgery was successfully developed, and the clinical investigation demonstrated that the PROM had satisfactory feasibility, reliability, and validity. Further studies are possible based on our PROM, and data on a larger scale may reveal more information on patients' subjective feelings about orthognathic surgery.

CLINICAL SIGNIFICANCE

The novel PROM provides a systematic and scientific way to evaluate the patient's subjective feelings to help surgeons obtain complete patient-reported information after orthognathic surgery. Additionally, standardised multicentre research on patients' subjective feelings using our PROM is possible and could improve the effectiveness of the evaluation and help maintain treatment quality.
