Hearing loss (HL) is one of the most common health problems for people aged 65 years and above1, the growing number of hearing-impaired older adults is a natural result of our growing elderly population2. The prevalence of hearing impairment rapidly increases with increasing age. It is estimated that it affects 48% of individuals in their 60s, 60% in their 70s3,4, and 90% of people aged 80 years and above.5,6 . The degree of hearing aid use has increased in the past decades, but the level of usage remains insufficient. Over the last 20 years, hearing aid adoption has remained stubbornly at about one in five adults with an admitted hearing loss. Even among those who possess a hearing aid, a substantial proportion never or scarcely uses their hearing aid. In addition, not all adults provided with hearing aids use them, wear them regularly, or are satisfied with them. Surveys conducted in the United Kingdom, Australia, Finland, Denmark, and the United States revealed that between 1% and 40% of hearing aids dispensed are never or rarely used. Primary clinical management intervention for people with hearing loss is hearing aids. The majority of people who would benefit from hearing aid do not use it. Although there is large prevalence of hearing impairment in human population, the uptake and use of hearing aid is still poor. Over the last 20 years, hearing aid adoption has remained at 20% with an admitted hearing loss.
It is necessary to identify the factors that affect compliance with this treatment recommendation. Some investigators have explored the barriers that may prevent those with hearing loss from choosing to purchase and use hearing aids to assess with their communication needs. Among some of the barriers to hearing aid adoption are that they can hear well most situations without hearing aid, hearing not severe enough can’t afford and need medicines. Many of the reasons why older adults with hearing impairment choose not to wear their hearing aids according to advice represent root causes of vision and handling problems, ringing sensations, disappointment with hearing aids, un natural sound and too embarrassed to wear their hearing aid in public.
Rationale For Proposed Study
The aim of the study was to find out obstacles regarding hearing aid adoption and not using hearing aid according to advice and to collate the available evidence as to the potential barriers for non-use of hearing aids.
To seek the obstacles regarding hearing aid adoption and use in older adults of age equal to and greater than fifty years coming to audiology department Chiniot.
1.2. Operational Definitions
An obstacle is something, material or non-material, that blocks one’s way or prevents or hinders progress. Obstacles which prevent progress to better hearing by using hearing aids in older adults are cost and quality of hearing aids, expectations, physical and cognitive restrictions, stigmatization, wax accumulation, poor amplification and some medicals conditions etc. Older adults who were reluctant to purchase and use hearing aid most often in their everyday lives were studied. We couldn’t operationalize each obstacle so we accepted them on subjective basis as patient told us.
2.1. Research Hypothesis:
· There are many obstacles regarding hearing aid adoption and use in older adults of age greater than and equal to fifty years.
2.2. Null Hypothesis:
· There are no obstacles regarding hearing aid adoption and use in older adults of age greater than and equal to fifty years.
3. METHODS & MATERIALS
3.1. Setting: This study will be conducted in audiology department of district headquarter hospital Chiniot.
3.2. Study Design: Cross sectional descriptive study
3.3. Sample Size: Due to limited availability of time and resources sample size will be 40 older adults of age ? 50 years.
3.4. Sampling Technique: Non probability Convenience Sampling
3.5. Duration of Study: The duration of study will be nine months after approval of synopsis.
3.6. Ethical issues:. Ethical approval will be taken from Hospital ethical committee DHQH, Chiniot.
3.7. Selection Criteria:
Hearing impaired older adults of age ? 50 years.
Older adults who were prescribed hearing aid from one month but have not adopted yet and those who were not using according to the advice of audiologist.
Exclusion criteria: Labeled psychiatric patients and those who were not willing to participate were excluded.
3.8. Data Collection:
Data was collected with the help of pre-tested questionnaire which consists of two parts. The first part was demographic variables (name, age, gender, residence, socioeconomic status, monthly income and occupation). Study variables (hearing not severe enough, hear well in most situations without hearing aid, vision and handling problems, ringing sensations and disappointment with hearing aids).
3.9. Data Analysis:
Data was analyzed through manually.
3.10 Data Presentation:
o Frequency and percentages were calculated and data was presented in the form of graphs, tables and charts.
