Performance and QOL after Geriatric Cochlear Implantation

Abstract

Objective To assess audiologic performance and quality of life in geriatric cochlear implantation patients and to determine whether comorbid medical conditions, etiology, and duration of hearing loss impact audiologic and quality of life outcomes. Methods Geriatric patients who underwent cochlear implantation between 1990 and 2006 were evaluated. Inclusion criteria were 55 years of age or older at time of implantation and post-lingual hearing loss. Patients with primary language other than English were excluded. 49 cochlear implant recipients were identified. A group of younger implanted patients was used as a control. All patients completed standardized audiologic tests including the Hearing In Noise Test. Validated surveys, including the Glasgow Benefit Inventory and the Hearing Handicap Inventory for the Elderly, were used to assess quality of life. Results The mean age at implantation was 69.5 (range 58–85) and the average time interval from the implantation to the completion of the surveys was 73.2 months (6 to 229). Identified comorbid conditions included hypertension, diabetes, and malignancies, among others. Audiologic performance and quality of life scores between the two groups were similar. In the geriatric group there was no difference in patient satisfaction between subgroups with 0–1, 2–3 or > 3 comorbid conditions. Conclusions Our results suggest that the audiologic performance and quality of life scores between the older and younger age groups are similar. In the geriatric group associated comorbidities did not interfere with patient satisfaction as assessed by survey instruments.
