Abstract

OBJECTIVE: To investigate the effect of hearing aid (HA) intervention on long-term health-related quality of life (HRQoL) changes in first-time and experienced HA users using the 15D questionnaire. Secondly, the study explored the relationship between clinical parameters and changes in 15D scores.

DESIGN: A prospective observational study.

STUDY SAMPLE: The study population included 1562 patients (1113 first-time and 449 experienced HA users) referred for HA rehabilitation. All patients responded to the 15D at baseline, two months after HA fitting, and at long-term follow-up (698 ± 298 d).

RESULTS: Among both first-time and experienced HA users, significant improvements in hearing-dimension (15D-3) score were observed at two-month follow-up which sustained at long-term follow-up. 15D total scores significantly decreased at long-term follow-up. Self-reported hearing abilities, word recognition scores, and HA use time were significantly and positively correlated to increased 15D.

CONCLUSIONS: Both groups of HA users reported improved hearing-related QoL after HA treatment which sustained at long-term follow-up but the improvement in total 15D total score did not sustain for either group. The results suggest that HA intervention positively affects hearing-related QoL among older adults with hearing loss, and the findings support the use of 15D as a tool for the evaluation of HA treatment effects.
