Objectives: Reasons for non-use of hearing aids are varied, but many studies have suggested that a lack of knowledge about how to use and/or take care of the hearing aids is a major factor. This is not surprising given that other healthcare fields have reported that between 40-80% of information provided during a clinical appointment is forgotten by the patient immediately after the appointment and almost half of what is remembered is not correct. The long-term goal of this project is to improve the delivery of information during the hearing-aid orientation, as better delivery of information will result in better hearing-aid handling skills and thus better overall hearing-aid outcomes. To accomplish this goal, the investigators propose to refine and evaluate the effectiveness of three forms of supplemental hearing-aid-orientation tools, each of which was developed using established guidelines for good patient-provider communication.
Plan: The purpose of the proposed application is to evaluate the relative effectiveness of four forms of hearing-aid orientation provided to first time hearing-aid users, three of which use some of the aforementioned strategies to enhance the standard of care. The four forms of orientation will be: (1) the standard-of-care hearing-aid orientation; (2) the standard of care plus provision a hearing-aid information guide (HAIG) (3) the standard of care supplemented by an explanation of its content using the talk-back technique to confirm patient understanding; and (4) the standard of care plus provision of a take-home hearing-aid orientation DVD (HAO DVD). The content of the HAIG will be field tested and finalized following input obtained via focus groups with clinical audiologists and first-time hearing aid users.
Methods: For the field testing up to 16 clinical audiologists and 10 new hearing aid user Veterans will be recruited to participate in focus groups during which they will view and then be asked questions about the content of the HAIG. Information learned during these focus groups will then be incorporated into the HAIG, at which time they will be ready for use in the study. For the comparative effectiveness study, up to 468 hearing-impaired Veterans who are about to become first-time hearing-aid users will be enrolled to participate in this investigation. These individuals will be recruited from the VA Portland Health Care System's Audiology and Speech Pathology Service (ASPS). Prior to receiving their hearing aids, subjects will be enrolled in the study at the National Center for Rehabilitative Auditory Research (NCRAR), and will conduct health literacy, manual dexterity and hepatic sensitivity, visual acuity, and learning and memory assessments. They will then attend their hearing aid fitting in the ASPS and will receive standard-of-care hearing-aid orientation. At the end of that appointment, they will receive one of the four study interventions. Subjects will return to the NCRAR 4-6 weeks after the hearing-aid-fitting appointment to complete the following outcome measures: a knowledge and practical test regarding hearing-aid use and care, a measure of self-efficacy, and a measure of hearing-aid outcomes. They also will be interviewed so that the investigators can learn their opinions about the intervention. A subset of the initial 50 participants enrolled into each study arm will attend a second follow-up appointment 6 months after the fitting appointment so the investigators can examine longer-term impacts of the hearing aid orientation interventions.
