RESUMO
PURPOSE: To assess obstructive sleep apnea (OSA)-related experience, knowledge, attitude, and behaviors among orthodontic professionals in China and identify factors associated with their knowledge levels, attitude toward referring, and self-confidence in the management of patients with OSA. METHODS: An online cross-sectional survey was conducted using a 31-item questionnaire developed with a professional online survey tool ( www.wjx.cn ) and distributed via WeChat (Tencent, Shenzhen, China). Data were collected between January 16 and 23, 2022 and analyzed using the chi-square test, Fisher's exact test, and multivariate generalized estimation equations. RESULTS: A total of 1760 professionals responded to the survey, and responses to 1611 questionnaires were valid. The average score of correct answers to the 15 OSA knowledge questions was 12.1 ± 2.0. Most of the professionals agreed that it was necessary to identify patients who might have OSA in practice. The top three sources for gaining knowledge of OSA according to the survey were classrooms and textbooks (76.3%), medical lectures (75.7%), and academic conferences (73.2%). The level of knowledge was significantly correlated with self-confidence in treatment (P < 0.001) and willingness to refer patients to otolaryngologists or clinicians of related disciplines (P < 0.001). CONCLUSIONS: Most orthodontic professionals agreed that there was a need to identify patients with OSA and learn further about related problems. Treatment confidence and willingness of professionals to refer patients were related to the level of OSA knowledge. These findings suggest that promotion of OSA-related education may help improve the care of patients with OSA.
