Abstract

The purpose of this study was to investigate the efficiency of the Swiss hearing aid dispensing system, and to determine factors contributing to successful hearing aid provision. A national cross sectional survey was performed using a postal questionnaire with 8707 adult hearing aid owners (response rate 62%). To correct results for a potential non-response bias, 193 randomly selected non-respondents were contacted by telephone. Data on hearing loss and type of hearing aid were provided by the hearing aid dispensing practice. Logistic regression analyses were performed to identify determinants of non-regular use and dissatisfaction. Eighty-five percent used their device(s) regularly, 12% only occasionally and 3% never. Eighty percent were satisfied with their aids. Non-regular use of hearing aids was significantly associated with age, gender, regional language, total duration of use, type of amplification, hearing aid category, hearing loss, and dissatisfaction with and difficulties in managing the aid. Dissatisfaction was associated with regional language, total duration of use, difficulties in managing the aid, and non-regular use. It was concluded that rates of regular hearing aid use and satisfaction are high in Switzerland.

Sumario

El propósito de este estudio fue investigar la eficiencia del sistema suizo de otorgamiento de auxiliares auditivos, y determinar los factores que contribuyen al suministro exitoso de dichos auxiliares. Se realizó una encuesta nacional transversal aplicando un cuestionario postal a 8.707 adultos que utilizaban auxiliares auditivos (tasa de respuesta 62%). Para corregir los resultados en cuanto a sesgos potenciales de no respuesta, 193 sujetos que no respondieron fueron seleccionados al azar y contactados por teléfono. Se obtuvieron los datos sobre la pérdida auditiva y el tipo de auxiliar auditivo a partir del sistema de otorgamiento de auxiliares auditivos. Se realizaron análisis de regresión logística para identificar determinantes del uso no regular y de la falta de satisfacción. Ochenta y cinco por ciento utilizaban su(s) dispositivo(s) regularmente, 12% sólo en forma ocasional y 3% nunca lo hacían. Ochenta por ciento estaban satisfechos con sus auxiliares. El uso no regular de los auxiliares auditivos se asoció significativamente con la edad, el género, el lenguaje regional, la duración total del uso, el tipo de amplificación, la categoría del auxiliar auditivo, la pérdida auditiva, y la insatisfacción, así como las dificultades para el manejo del auxiliar. La insatisfacción se asoció con el lenguaje regional, la duración total del uso, dificultades en el manejo del auxiliar y el uso no regular. Se concluyó que en Suiza las tasas de uso regular del auxiliar auditivo y la satisfacción son altas.
