Comparing outcomes of ultra-low-cost hearing aids to programmable, refurbished hearing aids for adults with high frequency hearing loss in Malawi: a feasibility study.

Introduction: Access to ear and hearing health services are limited or non-existent in low-income countries, with less than 10% of the global production of hearing aids distributed to this population. The aim of this feasibility study was to compare the outcomes of an ultra-low-cost hearing aid (LoCHAid) to programmable, refurbished hearing aids for adults with high-frequency hearing loss, in Blantyre, Malawi. Methods: Sixteen adults with high frequency hearing loss, and no prior experience of hearing aids, took part in this study, nine were fitted with the LoCHAid and seven were fitted with refurbished, programmable hearing aids, for a one-month trial. Five standardized hearing qualities questionnaires were used to compare outcomes pre and post device fitting and between devices. Questionnaire scales were analysed using general linear models and inductive thematic analysis was used to evaluate qualitative data. Results: Overall, there was no significant difference found between LoCHAid and refurbished hearing aids, and the two device types each showed a similar degree of improvement after fitting. Qualitative data analysis identified two key themes: Sound Quality and User experience. Conclusion: The results from this feasibility study are encouraging, but a comprehensive, larger clinical study is needed to draw firm conclusions about the LoCHAid's performance. This study has identified key improvement indicators required to enhance sound quality and user experience of the LoCHAid.

Attitudes towards hearing difficulties, health-seeking behaviour, and hearing aid use among older adults in Thailand.

Introduction: This qualitative study explores older adults' attitudes towards hearing difficulties, health-seeking behaviour and hearing aid use in Samutprakarn, Thailand. Method: Three focus groups (n=25), with adults aged 60-88 years, were conducted within a residential complex for older adults. Qualitative data analysis, employing a phenomenological approach was completed. Results: Four themes are presented: (1) Perception of hearing difficulties, (2) Experience of receiving care, (3) Attitudes towards wearing hearing aids, and (4) Raising awareness of hearing difficulties in older adults. Findings indicate that Thai older adults may not be aware or accepting of their hearing difficulties, due to the stigma associated hearing loss, older age, and disability. The consequential impact of these unacknowledged issues manifest in communication challenges and the adoption of avoidance behaviours across diverse situational contexts. Conclusion: This study enhances our understanding of how Thai older adults perceive hearing problems and ear care. Findings underscore the potential pivotal role of familial and social networks in mitigating barriers associated with hearing difficulties among older adults in Thailand. These insights can raise awareness and inform effective management for older adults and their families. Additionally, the findings could guide healthcare providers, researchers, and policy makers, fostering improved care for this demographic.

Factors Affecting the Use of Speech Testing in Adult Audiology.

OBJECTIVE: The aim of this study was to evaluate hearing health care professionals' (HHPs) speech testing practices in routine adult audiology services and better understand the facilitators and barriers to speech testing provision. DESIGN: A cross-sectional questionnaire study was conducted. STUDY SAMPLE: A sample (N = 306) of HHPs from the public (64%) and private (36%) sectors in the United Kingdom completed the survey. RESULTS: In the United Kingdom, speech testing practice varied significantly between health sectors. Speech testing was carried out during the audiology assessment by 73.4% of private sector HHPs and 20.4% of those from the public sector. During the hearing aid intervention stage, speech testing was carried out by 56.5% and 26.5% of HHPs from the private and public sectors, respectively. Recognized benefits of speech testing included (a) providing patients with relatable assessment information, (b) guiding hearing aid fitting, and (c) supporting a diagnostic test battery. A lack of clinical time was a key barrier to uptake. CONCLUSIONS: Use of speech testing varies in adult audiology. Results from this study found that the percentage of U.K. HHPs making use of speech tests was low compared to that of other countries. HHPs recognized different benefits of speech testing in audiology practice, but the barriers limiting uptake were often driven by factors derived from decision makers rather than clinical rationale. Privately funded HHPs used speech tests more frequently than those working in the public sector where time and resources are under greater pressure and governed by guidance that does not include a recommendation for speech testing. Therefore, the inclusion of speech testing in national clinical guidelines could increase the consistency of use and facilitate the comparison of practice trends across centers.

The impact of COVID-19 on provision of UK audiology services & on attitudes towards delivery of telehealth services.

OBJECTIVE: To (i) identify the impact of COVID-19 on provision of UK audiology services across sectors (ii) compare teleaudiology service provision between private and public sectors before and after the introduction of restrictions and (iii) identify barriers to teleaudiology delivery amongst UK hearing care professionals in both sectors. DESIGN: A mixed-methods cross-sectional survey study design. Responses to the structured questionnaire were analysed using descriptive and non-parametric statistics. STUDY SAMPLE: UK based hearing care professionals (HCP) (n = 323) completed the survey (218 public sector; 89 private sector). RESULTS: Changes in working patterns varied greatly between different sectors, with 61% of national employed and 26% of independent HCPs being furloughed, compared with 1% in the public sector. Use of telehealth was under-utilised across all sectors and groups in UK hearing healthcare, despite 92% of public and 75% of private HCPs reporting feeling comfortable conducting remote consultations. CONCLUSION: This study highlights a variation in teleaudiology adoption and key barriers across sector in the UK. A collaborative approach between hearing device manufacturers, research centres, HCPs and professional bodies is required for the creation of targeted guidance and training materials according to sector, to support clinicians in effective teleaudiology provision.

International survey of audiologists during the COVID-19 pandemic: use of and attitudes to telehealth.

OBJECTIVE: To determine the attitudes of audiologists towards telehealth and use of telehealth for the delivery of ear and hearing services pre-, during- and post- the COVID-19 pandemic, and to identify the perceived effects of telehealth on services and barriers to telehealth. DESIGN: An online survey distributed through the International Society of Audiology and member societies. STUDY SAMPLE: A total of 337 audiologists completing the survey between 23 June and 13 August 2020. RESULTS: There was a significant increase in the perceived importance of telehealth from before (44.3%) to during COVID-19 (87.1%), and the use of telehealth previous (41.3%), current (61.9%) and expected use of telehealth (80.4%). Telehealth was considered adequate for many audiology services, although hearing assessment and device fitting by telehealth received least support. Matters related to timeliness of services and reduction of travel were reported as the main advantages, but relationships between practitioners and clients may suffer with telehealth. Important barriers were technologies related to the client or remote site; clinic-related items were moderate barriers, although more clinician training was a common theme provided through open-ended responses. CONCLUSION: The COVID-19 pandemic has resulted in audiologists having a more positive attitude towards and greater use of telehealth, but with some reservations.

Experienced hearing aid users' perspectives of assessment and communication within audiology: a qualitative study using digital methods.

OBJECTIVE: To explore experienced hearing aid users' perspectives of audiological assessments and the patient-audiologist communication dynamic during clinical interactions. DESIGN: A qualitative study was implemented incorporating both an online focus group and online semi-structured interviews. Sessions were audio-recorded and transcribed verbatim. Iterative-inductive thematic analysis was carried out to identify themes related to assessment and communication within audiology practice. STUDY SAMPLES: Seven experienced hearing aid users took part in an online focus group and 14 participated in online semi-structured interviews (age range: 22 - 86 years; 9 males, 11 females). RESULTS: Themes related to assessment included the unaided and aided testing procedure and relating tests to real world hearing difficulties. Themes related to communication included the importance of deaf aware communication strategies, explanation of test results and patient centred care in audiology. CONCLUSION: To ensure hearing aid services meet the needs of the service users, we should explore user perspectives and proactively adapt service delivery. This approach should be ongoing, in response to advances in hearing aid technology. Within audiology, experienced hearing aid users' value (1) comprehensive, relatable hearing assessment, (2) deaf aware patient-audiologist communication, (3) accessible services and (4) a personalised approach to recommend suitable technology and address patient specific aspects of hearing loss.

Involving Children and Teenagers With Bilateral Cochlear Implants in the Design of the BEARS (Both EARS) Virtual Reality Training Suite Improves Personalization.

Older children and teenagers with bilateral cochlear implants often have poor spatial hearing because they cannot fuse sounds from the two ears. This deficit jeopardizes speech and language development, education, and social well-being. The lack of protocols for fitting bilateral cochlear implants and resources for spatial-hearing training contribute to these difficulties. Spatial hearing develops with bilateral experience. A large body of research demonstrates that sound localisation can improve with training, underpinned by plasticity-driven changes in the auditory pathways. Generalizing training to non-trained auditory skills is best achieved by using a multi-modal (audio-visual) implementation and multi-domain training tasks (localisation, speech-in-noise, and spatial music). The goal of this work was to develop a package of virtual-reality games (BEARS, Both EARS) to train spatial hearing in young people (8-16 years) with bilateral cochlear implants using an action-research protocol. The action research protocol used formalized cycles for participants to trial aspects of the BEARS suite, reflect on their experiences, and in turn inform changes in the game implementations. This participatory design used the stakeholder participants as co-creators. The cycles for each of the three domains (localisation, spatial speech-in-noise, and spatial music) were customized to focus on the elements that the stakeholder participants considered important. The participants agreed that the final games were appropriate and ready to be used by patients. The main areas of modification were: the variety of immersive scenarios to cover age range and interests, the number of levels of complexity to ensure small improvements were measurable, feedback, and reward schemes to ensure positive reinforcement, and an additional implementation on an iPad for those who had difficulties with the headsets due to age or balance issues. The effectiveness of the BEARS training suite will be evaluated in a large-scale clinical trial to determine if using the games lead to improvements in speech-in-noise, quality of life, perceived benefit, and cost utility. Such interventions allow patients to take control of their own management reducing the reliance on outpatient-based rehabilitation. For young people, a virtual-reality implementation is more engaging than traditional rehabilitation methods, and the participatory design used here has ensured that the BEARS games are relevant.

Development of a public audiology service in Southern Malawi: profile of patients across two years.

OBJECTIVE: To describe the profile of patients attending the Queen Elizabeth Central Hospital (QECH) audiology clinic in Malawi, over a two-year period (2016-2017). DESIGN: A retrospective patient record review. STUDY SAMPLE: There were 2299 patients assessed at the QECH audiology department between January 2016 and December 2017. Adult patients' ages ranged from 18 to 94 years (M = 45.8, SD = 19.22). The mean age of children included in this study was 7.7 years (SD= 5.21). Overall, 45.4% of patients were female. RESULTS: Of the 61.6% of adults and 41.7% of children found to have some degree of hearing loss, 28.3% and 15.4% were fitted with hearing aids, respectively. The number of patients seen in 2017 (n = 1385) was 34% higher than that of 2016 (n = 914). CONCLUSION: This study found that demand for hearing services is increasing in this public sector Malawian audiology department but uptake of hearing aids for those in need is low. Future evaluation of service provision and treatment outcomes is needed. Results from this study can be used to inform the development of future audiology clinics in low resource settings.
