The aims of the Improving Communication with Formal/Informal Caregivers among Older Adults with Dual Sensory Impairment: Feasibility of Hearing Intervention in a Low Vision Rehabilitation Clinic (LVR) are:
Primary aims Aim 1 To characterize prevalence of objective hearing impairment (i.e. DSI) among a clinical LVR population) in older adults (≥60 years) with English proficiency free from moderate to severe depression or cognitive decline using the Hearing Handicap Inventory for the Elderly (HHIE) assessment and an objective hearing evaluation.
Aim 2 To describe the perceived burden of care on primary caregiver (identified people who assist with two or more activities of daily living. instrumental activities of daily living (ADLs/Instrumental activities of daily living (IADLs))of individuals with dual sensory impairment (DSI) among a clinical LVR population in older adults (≥60 years) with English proficiency free from moderate to severe depression or cognitive decline using the Zarit Burden Interview questionnaire and qualitative interview data analyses.
Aim 3 To determine feasibility and benefit of a pilot manualized over-the-counter hearing intervention program on LVR patients to address communication among a DSI population using the Zarit Burden Interview questionnaire.
3A: Describe feasibility based on completion of pilot, drop-out rate, and semi-structured interviews 3B: Describe perceived communication improvements based on semi-structured interviews
The pilot is a prospective cohort study. Approximately 100 participants and their identified people who assist with two or more ADLs/IADLs will be assessed for DSI prevalence and DSI impact on communication. A sub-cohort of 10 participants with DSI will be provided a hearing intervention and followed for 4-6 weeks to assess the over-the-counter hearing intervention program's impact on communication among a DSI population and its identified people who assist with two or more ADLs/IADLs.
Recruitment will be based at the Wilmer Eye Institute (East Baltimore location) LVR clinic. Recruitment efforts will focus on older adults (≥60 years) with English proficiency attending the LVR clinic. Caregivers will be identified based on self-report assistance with at least two ADLs and/or IADLs.
The hearing intervention, for the sub-cohort of 10 individuals with DSI and their identified people who assist with two or more ADLs/IADLs, consists of instruction and best-practices provided by an occupational therapist on the utilization of a handheld amplifier (SuperEar SE9000). Prior to the LVR session with the handheld amplifier, individuals with DSI will complete a daily functioning (ADLs/IADLs) questionnaire (a measure of LVR success). The occupational therapist will give participant a handheld amplifier (SuperEar SE9000) and provide instruction on device use and best-practices (i.e. reducing background noise) to improve communication for the patient-caregiver pairs.
Participant-caregiver pairs will utilize the device and communication strategies over a 4-6-week period between LVR visits. Upon return, pairs will complete semi-structured interviews to elicit information about utilization (successes, barriers), impact on communication, and open qualitative feedback. Participants and caregivers will complete post-intervention functioning questionnaire and Zarit Burden Interview, respectively.

| Prevalence of Dual Sensory Impairment | Measured by the Hearing Handicap Inventory for the Elderly (HHIE), an assessment of perceived impact of hearing impairment, and an objective hearing evaluation (by pure tone audiometry a four-frequency test in both ears. Hearing impairment score >25dB in better ear). Total HHIE score: summation of 10 items (0, 2 or 4 points per item, total score range 0 to 40). 0-8 = no handicap; 10-24 = mild to moderate handicap; 26-40 = severe handicap. | 1 day |

| Impact of Dual Sensory Impairment on Formal/informal Caregivers by 12 Question Zarit Burden Interview Questionnaire (Range 0-48, 0-10 mild burden, 10-20 mild to moderate burden, >20 high burden) | Caregivers defined as identified people who assist with two or more ADLs/IADLs). Impact measured by a 12 item Zarit Burden Interview Questionnaire(ZBI-12) to assess burden of care. Total ZBI-12 score: summation of 12 items (0 to 4 points per item, total score range 0 to 48).

| Feasibility of Handheld Amplifier on Communication with Formal/Informal Caregivers as assessed by Semi Structured Interviews | Feasibility will be measured by semi-structured dyad interviews conducted with formal/informal caregiver and older adult participant pairs. Feasibility will then be determined qualitatively based on participants' response to the interview questions. | 4-6 Weeks |
| Impact of Handheld Amplifier on Caregiver Burden with Formal/Informal Caregivers as assessed by Zarit Burden Interview Questionnaire | Impact of hearing amplifier on dyad caregiver burden will be measured with ZBI-12. Total ZBI-12 score: summation of 12 items (0 to 4 points per item, total score range 0 to 48).
