Effect of hearing aids on hearing disability and quality of life in the elderly.Int J Audiol. 2006 Jul; 45(7):400-5.IJ
The aim of this study was to assess the effects of fitting a hearing aid by measuring the benefits derived from hearing aid use. Besides audiologic tests, a short version of the Hearing Handicap Inventory for the Elderly, and the EuroQol questionnaire were used in a prospective study. Ninety-eight first-time hearing aid users were interviewed prior to, and six months after, the fitting of their first hearing aids. The total HHIE-S score changed from 28.7 before, to 12.7 six months after, hearing aid fitting. Altogether 40%-60% of the users reported fewer social or emotional problems. There was a statistically significant positive change in the EQ-VAS score. According to the HHIE-S, hearing aids clearly alleviated hearing disability. The EQ-5D questionnaire was not sensitive enough for measuring the health-related quality of life of subjects with hearing impairment.
