ObjectiveThis study aimed to identify ear and hearing healthcare professionals' current knowledge, attitudes, and practices in caring for people with cognitive impairment and dementia in China. DesignA cross-sectional survey was distributed to eligible ear and hearing professionals in China. Knowledge, attitudes, and practices were compared among demographic factors. Linear regression assessed association between demographic information and survey responses. Structural equation model was used to identify mediation effects between knowledge, attitudes, and practices. Study sample334 ear and hearing healthcare professionals. ResultsRespondents showed high knowledge and positive attitude towards providing ear and hearing care to patients with potential cognitive impairment, but lower practice scores. Multiple regression analysis showed that professional role significantly influenced practice behaviors. Mediation analysis demonstrated that around 25% of the effect of knowledge on practice was mediated by attitude. ConclusionThis study found significant differences between knowledge, attitudes, and practice among Chinese ear and hearing professionals regarding cognitive impairment and hearing loss. There is a need for practice guidelines and training to enhance care for patients with comorbid hearing and cognitive impairments. Addressing the knowledge-practice gap will also require system-level supports, including multidisciplinary referral pathways and closer integration of hearing and cognitive health services.
