Brief Summary

Background: Prevalence of hearing loss increases over age; its estimated prevalence is 40-50% in people older than 75 years. Recent studies agree that modification in the hearing threshold contributes to deterioration in sociality, sensitivity, cognition, and quality of life of the elderly subjects.

Our study objective is to verify if rehabilitation with first time applied Hearing Aids (HA) in a cohort of old people with hearing impairment improves over time speech perception in a noisy environment and the overall health-related quality of life.

Methods: The monocentric, prospective, repeated measures, single-subject, clinical observational study will accrue 100 elderly, first-time HA recipients (≥ 65 years). The evaluation protocol is designed to analyze changes on specific measurement tools a year after the first HA fitting in comparison to the evaluation before HA usage.

Evaluations will consist of multiparametric details collected through self-report questionnaires completed by the recipients and a series of commonly used audiometric measures and geriatric assessment tools. The primary indicator of changes in speech perception in noise will be the OLSA test whereas the indicator of changes in overall quality of life will be the AQoL and HHEI questionnaires. Montreal Cognitive Assessment (MoCA) will help us to verify the cognitive state of the subjects. This questionnaire will allow us to exclude a reduction of the cognitive abilities over time.

Discussion: The protocol is designed to make use of measurement tools that have already been applied to the hearing-impaired population in order to compare the effects of HA rehabilitation in the elderly immediately before their first HA usage (Pre) and after gaining 1 year of experience (Post). The broad approach will lead to a greater understanding of how useful hearing influences the quality of life in elderly individuals, and thus improves potentials for healthy aging. Outcomes will be described and analyzed in detail.

Detailed Description

This study wants to identify significant improvement in speech recognition in noise in elderly patients (>= 65 years) that use HA for the first time and the correlations between the use of the HA and quality of life and cognitive status in elderly patients.

This is a repeated measure, single-subject, prospective observational study. No additional intervention is applied to population of HA recipients. Study subjects who use for the first time unilateral or bilateral hearing aids will be included. Eligible participants are consecutively identified on the HA registry of the Local Unit of the National Health System (NHS). Italian NHS is a welfare system which funds totally or partially the HA costs in selected patients.

An approximate number of 100 individuals will be included. The study design is monocentric and it is conducted at the outpatient service of the ENT Department of the "Saliceto" Hospital.

The test includes language-appropriate materials relative to the participating HA recipient.

The evaluation protocol is designed to coincide with routine clinical visits. Each subject is assessed with the full test-battery and questionnaires that are repeated at each of the two visits: one before the HA fitting (Pre) and one after one year of HA use (Post).

Subjects are enrolled in the clinical investigation only after signing the Patient Informed Consent Form prior to the first assessment (baseline, t0).

During the first assessment (Pre) are carried out this procedures: otoscopy and cleaning of the external auditory canal,- unaided pure tone audiometry, unaided speech audiometry in quiet, Italian version of Oldenburg Satztest (OLSA test) and Montreal Cognitive Assessment (MOCA), Hearing Handicap Inventory in the Elderly Screening test (HHIE-S) and Assessment of Quality of Life (AQoL) questionnaires.

During the second assessment (Post) are carried out: otoscopy and cleaning of the external auditory canal, test of the HA functioning, unaided pure tone audiometry, aided speech audiometry in quiet, Italian version of OLSA test and MOCA, HHIE-S, AQoL and International Outcome Inventory for Hearing Aids (IOI-HA) questionnaires.

The maximum administration time for completion of all measures is estimated to be approximately one hour of which 30 minutes are dedicated to standard self-report forms completed by the HA recipient.

In addition to general healthcare and patient-profile data, a selection of observational clinical assessment tools has been chosen for repeated evaluations to reflect changes in the hearing aid benefit and the overall health status of the elderly individual at post-HA use. These tools are commonly used in audiology and/or geriatric practices and are administered in the appropriate language. All questionnaires are validated for the Italian language.
