CEDRA: A Consumer Questionnaire to Detect Disease Risk Before Hearing Aid Purchase

To maintain consumer safety while dispensing hearing aids and other amplification devices when licensed providers are not involved, a multidisciplinary research team developed the Consumer Ear Disease Risk Assessment (CEDRA) questionnaire, which is designed to identify the risk of diseases with ear and hearing symptoms. Noted researcher Donald Nielsen, PhD, explains its development and how the self-administered test can be used online for free.
