Auditory Training for Adult Cochlear Implant Users: A Survey and Cost Analysis Study.

Abstract

The aims of this study were as follows: (a) to describe audiologists' practices toward auditory training (AT) for adult cochlear implant (CI) users with a postlingual hearing loss; and (b) to assess the cost of different AT methods for clients and service providers in comparison with no AT delivery. A survey was distributed to approximately 230 Australian CI audiologists to investigate the range, magnitude, and rationale of AT practices adopted as part of rehabilitation services with adult CI users. The cost of these different AT practices was then estimated from the perspectives of both clients and service providers, and compared against no AT delivery. Seventy-eight audiologists responded to at least one section of the survey (16% to 33% response rate), of which 85.5% reported that they viewed AT as a necessary component of rehabilitation. Home-based and face-to-face were the methods most frequently adopted to deliver AT. Methods used during training, such as stimuli type, feedback, and encouragement for training adherence, varied across respondents. The cost analysis indicated that home-based training resulted in the lowest program costs, whereas face-to-face AT (when delivered independently from routine appointments) was the method with highest cost for clients and service providers. The type of AT, recommended frequency of sessions, and overall duration of programs varied widely across respondents. Costs incurred by clients depended mainly on whether the AT was home-based or clinician-led (i.e., face-to-face, group-based), program fees, and travel arrangements made by clients, as well as clinicians' wages and the method chosen to deliver AT.
