eHealth and the hearing aid adult patient journey: a state-of-the-art review

Effectiveness of the HEAR-Aware App for Adults Not Ready for Hearing Aids, but Open to Self-Management Support: Results of a Randomized Controlled Trial

INTRODUCTION

Recently, the HEAR-aware app was developed to support adults who are eligible for hearing aids (HAs) but not yet ready to use them. The app serves as a self-management tool, offering assistance for a range of target behaviors (TBs), such as communication strategies and emotional coping. Using ecological momentary assessment and intervention, the app prompts users to complete brief surveys regarding challenging listening situations they encounter in their daily lives (ecological momentary assessment). In response, users receive educational content in the form of "snippets" (videos, texts, web links) on the TBs, some of which are customized based on the reported acoustic environmental characteristics (ecological momentary intervention). The primary objective of this study was to assess the effectiveness of the HEAR-aware app in enhancing readiness to take action on various TBs and evaluate its impact on secondary outcomes. The secondary objective was to examine the app's usability, usefulness, and user satisfaction.

METHODS

A randomized controlled trial design with two arms was used. Participants with hearing loss aged 50 years and over were recruited via an HA retailer and randomly assigned to the intervention group (n = 42, mean age = 65 years [SD = 9.1]) or the control group (n = 45, mean age = 68 years [SD 8.7]). The intervention group used the app during 4 weeks. The control group received no intervention. All participants completed online questionnaires at baseline (T0), after 4 weeks (T1), and again 4 weeks later (T2). Participants' readiness to take action on five TBs was measured with The Line Composite. A list of secondary outcomes was used. Intention-to-treat analyses were performed using Linear Mixed effect Models including group (intervention/control), time (T0/T1/T2), and Group × Time Interactions. In addition, a per protocol analysis was carried out to explore whether effects depended on app usage. For the secondary aim the System Usability Scale (SUS), the Intrinsic Motivation Inventory, item 4 of the International Outcome Inventory-Alternative Intervention (IOI-AI), and a recommendation item were used (intervention group only at T1).

RESULTS

For objective 1, there was no significant group difference for The Line Composite over the course of T0, T1, and T2. However, a significant (p = 0.033) Group × Time Interaction was found for The Line Emotional coping, with higher increase in readiness to take action on emotional coping in the intervention group than in the control group. The intention-to-treat analyses revealed no other significant group differences, but the per protocol analyses showed that participants in the intervention group were significantly more ready to take up Assistive Listening Devices (The Line Assistive Listening Devices) and less ready to take up HAs (Staging Algorithm HAs) than the control group (p = 0.049). Results for objective 2 showed that on average, participants rated the app as moderately useful (mean Intrinsic Motivation Inventory score 5 out of 7) and its usability as "marginal" (mean SUS score 68 out of 100) with about half of the participants rating the app as "good" (SUS score >70) and a minority rating is as "unacceptable" (SUS score ≤50).

DISCUSSION/CONCLUSIONS

This study underscores the potential of self-management support tools like the HEAR-aware app in the rehabilitation of adults with hearing loss who are not yet ready for HAs. The range in usability scores suggest that it may not be a suitable intervention for everyone.

Development of an Internet-based system to guide and telemonitor hearing aid users

PURPOSE

To develop and verify the usability of an internet-based system for telemonitoring and guidance of the hearing aid user as well as monitoring the long-term performance in a pilot group.

METHODS

The system "I can hear, but I can't understand" was developed based on recommendations in the literature regarding layout, design, and content for guidance and advice. Three stages were followed: planning, design and content development, and pilot testing. The sample consisted of 43 adults and older adults with any type and degree of hearing loss, who had been regularly using a hearing aid for at least 30 days and at most 24 months, with reading skills and no evidence of cognitive impairments. The individuals were followed up for 8 to 12 months. The users' performance was monitored with the Speech, Spatial and Qualities of Hearing Scale. The usability of this material was assessed with the System Usability Scale.

RESULTS

Improved performance and increased self-reported daily use of the hearing aid were observed after the period of guidance and telemonitoring via the system for all research participants. In all analyzes of the SUS scale, it was possible to observe a performance superior to 70 points, demonstrating good usability of the system. In the analysis of the performance of the SSQ, in the three moments of the research, a positive response was observed in all domains, thus showing progress in the use of hearing aids, with significant data for the domain of Hearing Speech.

CONCLUSION

The system "I can hear, but I can't understand" proved to be an easy-to-use and effective tool to telemonitor hearing aid users.

Digital vs. physical ear-nose-and-throat specialist assessment screening for complicated hearing loss and serious ear disorders in hearing-impaired adults prior to hearing aid treatment: a randomized controlled trial

Introduction

This study introduces a digital assessment tool for asynchronous and remote ear-nose-and-throat (ENT) specialist assessment screening for complicated hearing loss and serious ear disorders in hearing-impaired adults prior to hearing aid (HA) treatment. The +60 population will nearly double from 12% to 22% between 2015 and 2050 increasing the incidence of age-induced hearing impairment and the need for hearing rehabilitation. If un-diagnosed, age-related hearing loss negatively affects quality of life by accelerating social distancing and early retirement as well as increasing risk of anxiety, depression, and dementia. Therefore, innovative measures are essential to provide timely diagnostics and treatment.

Methods

A total of 751 hearing-impaired adults without previous HA usage or experience were randomly assigned to digital or physical ENT specialist assessment screening prior to HA treatment initiation in 20 public and private hearing rehabilitation and ENT specialist clinics in the North Denmark Region. A total of 501 test group participants were assigned to digital assessment screening and 250 control group participants to physical assessment screening prior to HA treatment.

Results

In all, 658 (88%) participants completed the trial and were eligible for analysis. Digital screening sensitivity (0.85, 95% confidence interval (CI) 0.71-0.94) was significantly higher than physical screening sensitivity (0.2, 95% CI: 0.03-0.56). Screening specificity was high for both assessment methods.

Discussion

In a setting where hearing-impaired adults were assessed for HA treatment, digital ENT specialist assessment screening did not compromise patient safety or increase the risk of misdiagnosis in patients with complicated hearing loss and/or serious ear disorders when compared to physical ENT specialist assessment screening.

Barriers and facilitators to paediatric caregivers' participation in virtual speech, language, and hearing services: A scoping review

Purpose

Virtual care-related technologies are transforming the way in which health services are delivered. A growing number of studies support the use of virtual care in the field of audiology and speech-language pathology; however, there remains a need to identify and understand what influences caregiver participation within the care that is virtual and family-focused. This review aimed to identify, synthesize, and summarize the literature around the reported barriers and facilitators to caregiver participation in virtual speech/hearing assessment and/or intervention appointments for their child.

Methods

A scoping review was conducted following the Joanna Briggs Institute manual for evidence synthesis. A search was conducted using six databases including MEDLINE, CINAHL, SCOPUS, ERIC, Nursing and Allied Health, and Web of Science to collect peer-reviewed studies of interest. Data was extracted according to a protocol published on Figshare, outlining a predefined data extraction form and search strategy.

Results

A variety of service delivery models and technology requirements were identified across the 48 included studies. Caregiver participation was found to vary across levels of attendance and involvement according to eight categories: Attitudes, child behavioral considerations, environment, opportunities, provider-family relationship, role in care process, support, and technology.

Conclusions

This review presents a description of the key categories reported to influence caregiver participation in virtual care appointments. Future research is needed to explore how the findings can be used within family-centered care models to provide strategic support benefiting the use and outcomes of virtual care.

Designing a Hearing Health Care Smartphone App With Ecological Momentary Assessment: A Qualitative Study of Audiologists' Perspectives

Purpose:

The purpose of this study was to explore the perspectives of audiologists to provide input into development of a smartphone application (app) to document the real-life listening difficulties and the listening environment of hearing aid candidates and users.

Method:

Two focus groups were conducted. Facilitators utilized a topic guide to generate participants' input and perspectives. The focus groups were audio-recorded and transcribed verbatim. The transcripts were then qualitatively analyzed using content analysis.

Study Sample:

The study samples were 10 audiologists (seven females) with 2- to 10-plus years of hearing aid fitting experience.

Results:

Three main categories were identified: (a) The mobile device app could provide meaningful information to help audiologists to counsel their clients, (b) the app could give clients an insight into their hearing difficulties, and (c) the app could help clients to self-manage their hearing condition.

Conclusion:

These findings suggest that audiologists may better understand their clients' real-life listening difficulties through the use of a mobile device app; however, further research is required to harness the benefits of such an app.

Using an Online Tool to Apply a Person-Centred Approach in Audiological Rehabilitation: A Pilot Study

This study aimed to explore the experiences of adult clients with hearing loss and their audiologists in using an online tool, the Living Well Tool (LWT), during initial audiology appointments. The LWT is designed to help clients identify when and where it is most important for them to communicate effectively and live well with hearing loss. A total of 24 adult clients with hearing loss and two audiologists participated in this study. Clients were invited to complete the LWT prior to their next audiology appointment, however, most clients chose to use the LWT in-session with their audiologist. Following the appointment, clients and audiologists participated in individual qualitative semi-structured interviews to explore their experiences of using the LWT, and the extent to which the LWT facilitated person-centred care. Qualitative analysis five key themes which reflected participants' experiences and perceptions of using the LWT: (1) the LWT enhances audiological care; (2) the LWT supports person-centred audiological care; (3) the use of the LWT should be individualised; (4) users value comprehensiveness; and (5) users value accessibility. This study demonstrated that the LWT supported the provision of person-centred audiological care, providing a flexible, comprehensive and accessible means for audiologists to gain an understanding of their clients' needs and preferences. However, it was also noted that the use of a tool must be individualised and accessible for all.

A randomised, controlled trial of clinically implementing online hearing support

Objective: The research-oriented objective of this study was to document the effectiveness of online support for hearing aid (HA) users compared with traditional support.Design: This study is a randomised controlled trial with parallel group design. The research-oriented objectives were evaluated using the Hearing Handicap Inventory for the Elderly (HHIE) and the Communication Strategies Scale (CSS) at baseline and immediately postintervention.Study sample: Selected clients at five different clinics were randomised to an intervention group (n = 78) that took part in online hearing support and a control group (n = 58) that received standard care.Results: The analyses (intention-to-treat) showed statistically significant improvements in the HHIE-total and Emotional subscale scores for the intervention group compared with the control group. The intervention group also showed significantly greater improvement in the CSS-total and Verbal and Nonverbal subscale scores. A subgroup analysis was performed including two groups: HA use <1 year and HA use >1 year. A statistically significant improvement was found for the HA users >1 year compared with HA use <1 year.Conclusions: It is effective to clinically include online hearing support for HA users when addressing self-perceived hearing difficulties and to sharpen communication strategy skills.

EHealth and Its Role in Supporting Audiological Rehabilitation: Patient Perspectives on Barriers and Facilitators of Using a Personal Hearing Support System With Mobile Application as Part of the EVOTION Study

Background

Hearing loss is a major public health challenge. Audiology services need to utilise a range of rehabilitative services and maximise innovative practice afforded by technology to actively promote personalized, participatory, preventative and predictive care if they are to cope with the social and economic burden placed on the population by the rapidly rising prevalence of hearing loss. Digital interventions and teleaudiology could be a key part of providing high quality, cost-effective, patient-centred management. There is currently very limited evidence that assesses the hearing impaired patient perspective on the acceptance and usability of this type of technology.

Aim

This study aims to identify patient perceptions of the use of a hearing support system including a mobile smartphone app when used with Bluetooth-connected hearing aids across the everyday life of users, as part of the EVOTION project.

Methods

We applied a questionnaire to 564 participants in three countries across Europe and analysed the following topics: connectivity, hearing aid controls, instructional videos, audiological tests and auditory training.

Key Findings

Older users were just as satisfied as younger users when operating this type of technology. Technical problems such as Bluetooth connectivity need to be minimised as this issue is highly critical for user satisfaction, engagement and uptake. A system that promotes user-controllability of hearing aids that is more accessible and easier to use is highly valued. Participants are happy to utilise monitoring tests and auditory training on a mobile phone out of the clinic but in order to have value the test battery needs to be relevant and tailored to each user, easy to understand and use. Such functions can elicit a negative as well as positive experience for each user.

Conclusion

Older and younger adults can utilise an eHealth mobile app to complement their rehabilitation and health care. If the technology works well, is tailored to the individual and in-depth personalised guidance and support is provided, it could assist maximisation of hearing aid uptake, promotion of self-management and improving outcomes.

A Comparison of the Use of Smart Devices, Apps, and Social Media Between Adults With and Without Hearing Impairment: Cross-sectional Web-Based Study

Background

eHealth and social media could be of particular benefit to adults with hearing impairment, but it is unknown whether their use of smart devices, apps, and social media is similar to that of the general population.

Objective

Our aim is to study whether adults with normal hearing and those with impaired hearing differ in their weekly use of smart devices, apps, and social media; reasons for using social media; and benefits from using social media.

Methods

We used data from a Dutch cohort, the National Longitudinal Study on Hearing. Data were collected from September 2016 to April 2020 using a web-based questionnaire and speech-in-noise test. The results from this test were used to categorize normal hearing and hearing impairment. Outcomes were compared using (multiple) logistic regression models.

Results

Adults with impaired hearing (n=384) did not differ from normal hearing adults (n=341) in their use of a smartphone or tablet. They were less likely to make use of social media apps on a smartphone, tablet, or smartwatch (age-adjusted odds ratio [OR] 0.67, 95% CI 0.48-0.92; P=.02). Use of social media on all devices and use of other apps did not differ. Adults with hearing impairment were more likely to agree with using social media to stay in touch with family members (OR 1.54, 95% CI 1.16-2.07; P=.003) and friends (age-adjusted OR 1.35, 95% CI 1.01-1.81; P=.046). Furthermore, they were more likely to agree with using social media to perform their work (age-adjusted OR 1.51, 95% CI 1.04-2.18; P=.03). There were no differences in the experienced benefits from social media.

Conclusions

The potential for eHealth is confirmed because adults with hearing impairment are not less likely to use smart devices than their normal hearing peers. Adults with hearing impairment are less likely to use social media apps on a smart device but not less likely to use social media on all types of internet-connected devices. This warrants further research on the types of social media platforms that adults with hearing impairment use and on the type of device on which they prefer to use social media. Given that participants with hearing impairment are more likely than their normal hearing peers to use social media to perform their work, use of social media may be seen as an opportunity to enhance vocational rehabilitation services for persons with hearing impairment.

Process Evaluation of an Online SUpport PRogram for Older Hearing Aid Users Delivered in a Cluster Randomized Controlled Trial

Objectives: To evaluate the process of implementing a web-based support program (SUPR) for hearing aid users in the Dutch dispensing setting in order to allow interpretation of the randomized controlled trial's results (positive effects on hearing-aid related outcomes; no effects on psychosocial outcomes).

Design: Measures: context of implementation, recruitment, SUPR's: reach, implementation fidelity, dose delivered, dose received, satisfaction, and benefit. Data collection: quantitative and qualitative.

Study Sample: One hundred thirty-eight clients (mean age 68.1 years; 60% male) and 44 dispensers completed questionnaires. Five clients and 6 dispensers participated in interviews and focus groups.

Results: Clients and dispensers were generally satisfied with SUPR's usefulness. SUPR-videos were watched by 7–37% of the clients. Around half of the dispensers encouraged clients to watch them or informed them about SUPR. Some clients found the SUPR-materials suboptimal, and changes in personnel and limited dispenser-training were barriers acting on a contextual level.

Conclusions: This study identified several factors that contributed to the success of SUPR. Others factors, acting on various levels (e.g., intervention material, dispensers, and implementation context), were suboptimal and may explain the absent psychosocial effects. The identified factors are important to consider in further development of SUPR, and in other web-based support programs.

Smartphone-Connected Hearing Aids Enable and Empower Self-Management of Hearing Loss: A Qualitative Interview Study Underpinned by the Behavior Change Wheel

OBJECTIVES

To identify patient-reported barriers and facilitators to using smartphone-connected hearing aids, using the Behavior Change Wheel (BCW) to understand experiences and how these can be addressed.

DESIGN

A single-center, prospective, observational study. Eight hearing aid users (new = 1, existing = 7; mean age = 71.75 years, SD = 5.23, range = 65 to 81 years) were identified through convenience sampling from 44 participants who took part in a 7-week evaluation of smartphone-connected hearing aids controlled by a prototype app. The app allowed users to manually control settings such as gain, noise reduction, and microphone directionality, preset, and customized programmes. Participants were assigned to one of two focus groups following trial of the app.

RESULTS

Focus group transcripts were thematically analyzed and underpinned by the COM-B (Capability, Opportunity, Motivation-Behavior) model and Theoretical Domains Framework to identify barriers and facilitators to using smartphone-connected hearing aids (the target behavior). Mapping of themes to the BCW allowed use of the Behavior Change Technique Taxonomy (version 1) to identify behavior change techniques that audiologists could implement in clinical practice to address the barriers and facilitators. Capability: The app increased participants' knowledge of hearing aid controls, encouraging use of the app for improved hearing loss self-management. However, barriers to using the app included perception of insufficient digital literacy skills for smartphone-connected hearing aid use and an increased cognitive load caused by decisions over which controls to use. Opportunity: Perceived smartphone norms (i.e., acceptable occasions to use smartphones) and differing listening contexts acted as both facilitators and barriers. Motivation: The ability to control hearing aid settings in any listening situation (e.g., to reduce noise) empowered users to successfully self-manage their hearing loss, leading to greater confidence and participation in everyday life. The app also reduced hearing aid-related and self-stigma, and the ability to self-adjust hearing aids benefitted both participants and communication partners. It was the adjustability and interaction afforded by the app that empowered users, rather than the hearing aid technology itself. Perceived beliefs and knowledge about digital literacy skills, and specifically abilities to use a smartphone, were perceived to be barriers in this typically older population, particularly when they compared themselves to younger generations. Using the Behavior Change Technique Taxonomy (version 1), behavior change techniques that could be used by audiologists to address these barriers included enablement, goal setting, reframing perceptions toward technology, and addressing patient educational needs.

CONCLUSIONS

Smartphone-connected hearing aids, when used in their everyday lives, were viewed positively by participants across a range of domains, empowering them and enabling hearing loss self-management. Audiologists should consider smartphone-connected hearing aid candidacy for all who have access to smartphones and are willing to use one. Use of the BCW has identified that modifiable barriers to using smartphone-connected hearing aids exist. Audiologists could use these evidence-based behavior change techniques to support patients in adopting and using these technologies to successfully self-manage hearing loss. Overall, by reframing smartphone technologies as a tool to remain connected with society, smartphone-connected hearing aids could shift the power of managing hearing loss from clinician to patient.

Disabilities and the Digital Divide: Assessing Web Accessibility, Readability, and Mobility of Popular Health Websites

With recognition of (1) unmet health information needs of persons with disabilities; and (2) anticipated growth of the persons with disabilities population, we seek to better understand the relative general accessibility of health information on popular, highly ranked health websites. That is, instead of examining the efficacy and impact of specific types of health message appeals, the present investigation assesses the functional performance of specific content platforms of health websites. We examine the components of accessing and understanding health information through the lens of web and language accessibility, readability, and mobility. A total of 139 health-focused websites were randomly sampled from the Alexa® "Top Sites" global ranking system which uses web traffic data to rank the most popular websites. The sample was processed using computer aided software (e.g., WEB AIM, Web FX & Google Test My Site.) We found 91.3% of sampled home pages had detectable accessibility failures. The most common accessibility failures were low contrast, empty links, missing ALT text, empty buttons, and missing form labels. Most websites offered neither an accessibility policy statement nor an option for automated language translation service, likely impacting those with limited English proficiency (LEP). The implications for these findings are reviewed with discussion and limitations provided.

How Can eHealth Meet the Hearing and Communication Needs of Adults With Hearing Impairment and their Significant Others? A Group Concept Mapping Study

OBJECTIVES

To seek the perspectives of key stakeholders regarding: (1) how eHealth could help meet the hearing and communication needs of adults with hearing impairment and their significant others; and (2) how helpful each aspect of eHealth would be to key stakeholders personally.

DESIGN

Group concept mapping, a mixed-methods participatory research method, was used to seek the perspectives of key stakeholders: adults with hearing impairment (n = 39), significant others (n = 28), and hearing care professionals (n = 56). All participants completed a short online survey before completing one or more of the following activities: brainstorming, sorting, and rating. Brainstorming required participants to generate ideas in response to the focus prompt, "One way I would like to use information and communication technologies to address the hearing and communication needs of adults with hearing loss and their family and friends is to…." The sorting task required participants to sort all statements into groups that made sense to them. Finally, the rating task required participants to rate each of the statements according to "How helpful would this idea be to you?" using a 5-point Likert scale. Hierarchical cluster analysis was applied to the "sorting" data to develop a cluster map using the Concept Systems software. The "rating" data were subsequently analyzed at a cluster level and an individual-item level using descriptive statistics. Differences in cluster ratings between stakeholder groups were examined using Kruskal-Wallis tests.

RESULTS

Overall, 123 statements were generated by participants in response to the focus prompt and were included in subsequent analyses. Based on the "sorting" data and hierarchical cluster analysis, a seven-cluster map was deemed to be the best representation of the data. Three key themes emerged from the data, including using eHealth to (1) Educate and Involve Others; (2) Support Aural Rehabilitation; and (3) Educate About and Demonstrate the Impacts of Hearing Impairment and Benefits of Hearing Rehabilitation. Overall median rating scores for each cluster ranged from 3.97 (educate and involve significant others) to 3.44 (empower adults with hearing impairment to manage their hearing impairment from home).

CONCLUSIONS

These research findings demonstrate the broad range of clinical applications of eHealth that have the capacity to support the implementation of patient- and family-centered hearing care, with self-directed educational tools and resources typically being rated as most helpful. Therefore, eHealth appears to be a viable option for enabling a more biopsychosocial approach to hearing healthcare and educating and involving significant others in the hearing rehabilitation process without adding more pressure on clinical time. More research is needed to inform the subsequent development of eHealth interventions, and it is recommended that health behavior change theory be adhered to for such interventions.

Evaluation of a Novel Speech-in-Noise Test for Hearing Screening: Classification Performance and Transducers Characteristics

One of the current gaps in teleaudiology is the lack of methods for adult hearing screening viable for use in individuals of unknown language and in varying environments. We have developed a novel automated speech-in-noise test that uses stimuli viable for use in non-native listeners. The test reliability has been demonstrated in laboratory settings and in uncontrolled environmental noise settings in previous studies. The aim of this study was: (i) to evaluate the ability of the test to identify hearing loss using multivariate logistic regression classifiers in a population of 148 unscreened adults and (ii) to evaluate the ear-level sound pressure levels generated by different earphones and headphones as a function of the test volume. The multivariate classifiers had sensitivity equal to 0.79 and specificity equal to 0.79 using both the full set of features extracted from the test as well as a subset of three features (speech recognition threshold, age, and number of correct responses). The analysis of the ear-level sound pressure levels showed substantial variability across transducer types and models, with earphones levels being up to 22 dB lower than those of headphones. Overall, these results suggest that the proposed approach might be viable for hearing screening in varying environments if an option to self-adjust the test volume is included and if headphones are used. Future research is needed to assess the viability of the test for screening at a distance, for example by addressing the influence of user interface, device, and settings, on a large sample of subjects with varying hearing loss.

Development of a protocol and a clinical tool to assess the audiological needs of younger and older adults with hearing loss

OBJECTIVE

To develop a protocol and a clinical tool to assess the audiological needs of younger and older adults with hearing loss.

DESIGN

A needs assessment protocol was developed based on recommendations of an expert panel, existing literature, the International Classification of Functioning, Disability and Health, client-centered care and goal setting. The protocol was reviewed by the expert panel. Semi-structured interviews were conducted with clinical audiologists to validate its content and explore its clinical applicability. A clinical tool was developed to make the administration of the protocol more uniform.

STUDY SAMPLE

15 experts and 14 clinical audiologists.

RESULTS

Feedback received from the participants (experts and clinicians) supported the content validity of the needs assessment protocol and clinical tool. The topics covered within the protocol and tool include: Audiological needs (activity limitations, participation restrictions, environmental factors), Living conditions (social networks, living environment), Personal factors, Discussion with the client to define the intervention plan, and Recommendations.

CONCLUSIONS

A protocol and a clinical tool were developed to help audiologists and clients undertake a comprehensive audiological needs assessment. The content validity of the protocol and tool were demonstrated. Their use can facilitate the delivery of a client-centered assessment using a uniform and comprehensive approach.

Hearing aid acquisition and ownership: what can we learn from online consumer reviews?

OBJECTIVE

To explore the publicised opinions of consumers actively participating in online hearing aid reviews.

DESIGN

A retrospective design examining data generated from an online consumer review website (www.HearingTracker.com). Qualitative data (open text responses) were analysed using the open source automated topic modelling software IRaMuTeQ (http://www.iramuteq.org/) to identify themes. Outputs were compared with quantitative data from the consumer reviews (short response questions exploring hearing aid performance and benefit, and some meta-data such as hearing aid brand and years of hearing aid ownership).

STUDY SAMPLE

1378 online consumer hearing aid reviews.

RESULTS

Six clusters within two domains were identified. The domain Device Acquisition included three clusters: Finding the right provider, device and price-point; Selecting a hearing aid to suit the hearing loss; Attaining physical fit and device management skills. The domain Device Use included three clusters: Smartphone streaming to hearing aids; Hearing aid adjustment using smartphone; and Hearing in noise.

CONCLUSIONS

Although online hearing aid consumers indicate positive performance on multiple-choice questions relating to hearing aid performance and benefit, their online reviews describe a number of barriers limiting their success. Hearing healthcare clinicians must employ a personalised approach to audiological rehabilitation to ensure individual clients' needs are met.

Validation of teleaudiology hearing aid rehabilitation services for adults: a systematic review of outcome measurement tools

PURPOSE

To investigate outcome measurement tools for the validation of teleaudiology hearing aid rehabilitation services for adults.

METHODS

A search strategy was developed to identify tools used to evaluate standard and teleaudiology hearing aid rehabilitation services for adults. A seven-domain hearing-health-care service model for validation was defined and used to analyse the applicability and suitability of patient- and service-centred tools. This model and the applicability and suitability criteria were based on the literature, the International Classification of Functioning (ICF) framework, and gold standard professional practice guidelines, which together formed the validation framework used in this study.

RESULTS

Eighteen tools were identified and assessed against the validation framework. These tools were found to primarily assess aspects in the patient communication domain and rarely in the domain of service provision. All the included tools had some applicable items for teleaudiology hearing aid services; three tools were judged as suitable and four partially suitable for validating these services.

CONCLUSION

Although there is a set of suitable tools available to validate teleaudiology hearing aid rehabilitation services, none of them cover all the seven domains of the validation model used by this review and few are focussed on a specific domain. Further improvement and/or development of new tools to comprehensively validate these services is still necessary. At this stage, this still limits clinical audiology practice research, especially in teleaudiology.IMPLICATIONS FOR REHABILITATIONOutcome measurement tools are crucial for assessing the validity of hearing rehabilitation services.Findings of this study inform clinicians and researchers on how and what to assess and use to evaluate teleaudiology and standard hearing aid rehabilitation services.The use of the proposed validation framework may facilitate the standardisation of validation of both face-to-face and remotely delivered audiology rehabilitation services and improve consistency of methodology and reported real-world outcomes across studies and thus, the evidence.

An mHealth App (Speech Banana) for Auditory Training: App Design and Development Study

Background

With the growing adult population using electronic hearing devices such as cochlear implants or hearing aids, there is an increasing worldwide need for auditory training (AT) to promote optimal device use. However, financial resources and scheduling conflicts make clinical AT infeasible.

Objective

To address this gap between need and accessibility, we primarily aimed to develop a mobile health (mHealth) app called Speech Banana for AT. The app would be substantially more affordable and portable than clinical AT; would deliver a validated training model that is reflective of modern techniques; and would track users’ progress in speech comprehension, providing greater continuity between periodic in-person visits. To improve international availability, our secondary aim was to implement the English language training model into Korean as a proof of concept for worldwide usability.

Methods

A problem- and objective-centered Design Science Research Methodology approach was adopted to develop the Speech Banana app. A review of previous literature and computer-based learning programs outlined current AT gaps, whereas interviews with speech pathologists and users clarified the features that were addressed in the app. Past and present users were invited to evaluate the app via community forums and the System Usability Scale.

Results

Speech Banana has been implemented in English and Korean languages for iPad and web use. The app comprises 38 lessons, which include analytic exercises pairing visual and auditory stimuli, and synthetic quizzes presenting auditory stimuli only. During quizzes, users type the sentence heard, and the app provides visual feedback on performance. Users may select a male or female speaker and the volume of background noise, allowing for training with a range of frequencies and signal-to-noise ratios. There were more than 3200 downloads of the English iPad app and almost 100 downloads of the Korean app; more than 100 users registered for the web apps. The English app received a System Usability Scale rating of “good” from 6 users, and the Korean app received a rating of “OK” from 16 users.

Conclusions

Speech Banana offers AT accessibility with a validated curriculum, allowing users to develop speech comprehension skills with the aid of a mobile device. This mHealth app holds potential as a supplement to clinical AT, particularly in this era of global telemedicine.

Using smartphone technology to support the adult audiologic rehabilitation journey

OBJECTIVE

Although the availability of mobile device applications (apps) to support people with hearing impairment is rapidly increasing, there are few reports of the use of such apps by the target population. The aim of this paper is to describe research that has applied apps at various stages of the adult rehabilitation journey.

DESIGN

A summary of studies utilising apps to investigate (1) the hearing difficulties and acoustic environments of adults with mild hearing impairment, (2) hearing aid benefit in this population and (3) useability of an app to guide hearing aid handling tasks.

STUDY SAMPLE

Older adults with no previous experience with hearing aids, who owned a smartphone or tablet and were confident in using apps. Participant samples ranged from 10 (hearing aid benefit pilot study, mean age = 70 years) to 30 participants (app useability study, mean age = 69 years).

RESULTS

All studies showed that smartphone apps can provide real-world insights during the early stages of the patient journey and hearing aid management support during the latter stages. App useability was rated positively by participants.

CONCLUSION

Smartphone apps may be used as a feasible complement to face-to-face interaction in audiology practice.

Effectiveness of a Web-Based SUpport PRogram (SUPR) for Hearing Aid Users Aged 50+: Two-Arm, Cluster Randomized Controlled Trial

BACKGROUND

Hearing aid (HA) use is known to improve health outcomes for people with hearing loss. Despite that, HA use is suboptimal, and communication issues and hearing-related activity limitations and participation restrictions often remain. Web-based self-management communication programs may support people with hearing loss to effectively self-manage the impact of hearing loss in their daily lives.

OBJECTIVE

The goal of the research is to examine the short- and long-term effects of a web-based self-management SUpport PRogram (SUPR) on communication strategy use (primary outcome) and a range of secondary outcomes for HA users aged 50 years and older.

METHODS

Clients of 36 HA dispensing practices were randomized to SUPR (SUPR recipients; n=180 HA users) and 34 to care as usual (controls; n=163 HA users). SUPR recipients received a practical support booklet and online materials delivered via email over the course of their 6-month HA rehabilitation trajectory. They were encouraged to appoint a communication partner and were offered optional email contact with the HA dispensing practice. The online materials included 3 instruction videos on HA handling, 5 videos on communication strategies, and 3 testimonial videos. Care as usual included a HA fitting rehabilitation trajectory only. Measurements were carried out at baseline, immediately postintervention, 6 months postintervention, and 12 months postintervention. The primary outcome measure was self-reported use of communication strategies (3 subscales of the Communication Profile for the Hearing Impaired [CPHI]). Secondary outcome measures included self-reported personal adjustment to hearing loss (CPHI); use, satisfaction and benefit of HAs and SUPR (use questionnaire; International Outcome Inventory for Hearing Aids [IOI-HA], Alternative Interventions [IOI-AI]); recommendation of HA dispensing services; self-efficacy for HA handling (Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids [MARS-HA]); readiness to act on hearing loss (University of Rhode Island Change Assessment adapted for hearing loss [URICA-HL]); and hearing disability (Amsterdam Inventory for Auditory Disability and Handicap [AIADH]).

RESULTS

Linear mixed model analyses (intention to treat) showed no significant differences between the SUPR and control group in the course of communication strategy use (CPHI). Immediately postintervention, SUPR recipients showed significantly higher self-efficacy for advanced HA handling than the controls, which was sustained at 12 months (MARS-HA; mean difference immediately postintervention: 5.3, 95% CI 0.3 to 10.4; P=.04). Also, SUPR recipients showed significantly greater HA satisfaction than controls immediately postintervention (IOI-HA; 0.3, 95% CI 0.09 to 0.5; P=.006), which was sustained at 12 months, and significantly greater HA use than the controls immediately postintervention (IOI-HA; 0.3, 95% CI 0.02 to 0.5; P=.03), which was not sustained at 12 months.

CONCLUSIONS

This study provides ground to recommend adding SUPR to standard HA dispensing care, as long-term, modest improvements in HA outcomes were observed. Further research is needed to evaluate what adjustments to SUPR are needed to establish long-term effectiveness on outcomes in the psychosocial domain.

Rationale, Theoretical Underpinnings, and Design of HEAR-aware: Providing Adults With Hearing Loss With Tailored Support to Self-Manage Their Hearing Problems via a Smartphone App, as an Alternative to Hearing Aids

Purpose An alarming two thirds of adults aged 50 years or over with hearing impairment who could benefit from hearing aids do not own any, leaving these adults with no support to self-manage their hearing problems. In the HEAR-aware project, it is hypothesized that self-management can be facilitated via a smartphone app if its educational content is tailored to a person's dynamic stage of readiness to take action on their hearing (stage of change) and to a person's dynamic acoustical situations (as measured via a wearable microphone) and associated challenges (as captured via ecological momentary assessment). As such, the HEAR-aware app would be an ecological momentary intervention. This research note describes the rationale and theoretical underpinnings of the app, as well as the rationale for planning a series of studies to develop and evaluate it. Study Designs After a preparatory phase, Study 1 includes qualitative group interviews to assess user needs. Next, a creative session will be held, in which all stakeholders involved will work toward a specified version of the app. Subsequently, prototypes of the app will be developed and pilot-tested (Pilot Studies 2A and 2B). Users' usage and ratings (usability and quality indicators) of the app's elements will be examined and processed in the app. Lastly, the effectiveness of the app's final version will be examined in a randomized controlled trial (Study 3). Discussion The project's merits and challenges will be discussed.

Applied tele-audiology research in clinical practice during the past decade: a scoping review

OBJECTIVE

The purpose of this scoping review was two-fold, (1) to provide information about the characteristics, type of service delivery, participant information and outcomes related to tele-audiology in clinical popluations, and (2) to describe documented facilitators and barriers to tele-audiology delivery from the perspectives of practitioners and service recipients. Knowledge of these findings can assist audiologists in considering remote service delivery options for their practices.

DESIGN

A scoping review was conducted in November 2019 to identify English-language peer-reviewed journal articles published from 1 January 2010 to 30 October 2019 related to remote clinical service delivery in audiology.

RESULTS

Thirty-six published research articles were included. Research studies were classified into four broad areas with some articles including more than one area within the scope of their article: Screening (n = 5), Diagnostic (n = 5), Intervention (n = 18), and Perspectives (n = 22).

CONCLUSION

Hearing healthcare service delivery is expanding with the changing technological landscape, providing greater opportunities and flexibility for audiologists and patients. There are clear opportunities for interdisciplinary collaboration and for collaboration with on-site local facilitators. Local facilitators, with training, can assist in connecting individuals to follow-up care, provide educational support, and needed hands-on assistance for specialised testing.

Features, Functionality, and Acceptability of Internet-Based Cognitive Behavioral Therapy for Tinnitus in the United States

Objective Although tinnitus is one of the most commonly reported symptoms in the general population, patients with bothersome tinnitus are challenged by issues related to accessibility of care and intervention options that lack strong evidence to support their use. Therefore, creative ways of delivering evidence-based interventions are necessary. Internet-based cognitive behavioral therapy (ICBT) demonstrates potential as a means of delivering this support but is not currently available in the United States. This article discusses the adaptation of an ICBT intervention, originally used in Sweden, Germany, and the United Kingdom, for delivery in the United States. The aim of this study was to (a) modify the web platform's features to suit a U.S. population, (b) adapt its functionality to comply with regulatory aspects, and (c) evaluate the credibility and acceptability of the ICBT intervention from the perspective of health care professionals and patients with bothersome tinnitus. Materials/Method Initially, the iTerapi ePlatform developed in Sweden was adopted for use in the United States. Functional adaptations followed to ensure that the platform's functional and security features complied with both institutional and governmental regulations and that it was suitable for a U.S. population. Following these adaptations, credibility and acceptance of the materials were evaluated by both health care professionals (n = 11) and patients with bothersome tinnitus (n = 8). Results Software safety and compliance regulatory assessments were met. Health care professionals and patients reported favorable acceptance and satisfaction ratings regarding the content, suitability, presentation, usability, and exercises provided in the ICBT platform. Modifications to the features and functionality of the platform were made according to user feedback. Conclusions Ensuring that the ePlatform employed the appropriate features and functionalities for the intended population was essential to developing the Internet-based interventions. The favorable user evaluations indicated that the intervention materials were appropriate for the tinnitus population in the United States.

Patient Uptake, Experience, and Satisfaction Using Web-Based and Face-to-Face Hearing Health Services: Process Evaluation Study

BACKGROUND

Globally, access to hearing health care is a growing concern with 900 million people estimated to suffer from disabling hearing loss by 2050. Hearing loss is one of the most common chronic health conditions, yet access to hearing health care is limited. Incorporating Web-based (voice calling, messaging, or emailing) service delivery into current treatment pathways could improve access and allow for better scalability of services. Current electronic health studies in audiology have focused on technical feasibility, sensitivity, and specificity of diagnostic hearing testing and not on patient satisfaction, experiences, and sustainable models along the entire patient journey.

OBJECTIVE

This study aimed to investigate a hybrid (Web-based and face-to-face) hearing health service in terms of uptake, experience, and satisfaction in adult patients with hearing loss.

METHODS

A nonprofit hearing research clinic using online and face-to-face services was implemented in Durban, South Africa, using online recruitment from the clinic's Facebook page and Google AdWords, which directed persons to an online Web-based hearing screening test. Web-based and face-to-face care pathways included assessment, treatment, and rehabilitation. To evaluate the service, an online survey comprising (1) a validated satisfaction measurement tool (Short Assessment of Patient Satisfaction), (2) a process evaluation of all the 5 steps completed, and (3) personal preferences of communication methods used vs methods preferred was conducted, which was sent to 46 patients who used clinic services.

RESULTS

Of the patients invited, 67% (31/46) completed the survey with mean age 66 years, (SD 16). Almost all patients, 92% (30/31) reported that the online screening test assisted them in seeking hearing health care. Approximately 60% (18/31) of the patients accessed the online hearing screening test from an Android device. Patients stayed in contact with the audiologist mostly through WhatsApp instant messaging (27/31, 87%), and most patients (25/31, 81%) preferred to use this method of communication. The patients continuing with hearing health care were significantly older and had significantly poorer speech recognition abilities compared with the patients who discontinued seeking hearing health care. A statistically significant positive result (P=.007) was found between age and the number of appointments per patient. Around 61% (19/31) of patients previously completed diagnostic testing at other practices, with 95% (18/19) rating the services at the hybrid clinic as better. The net promoter score was 87, indicating that patients were highly likely to recommend the hybrid clinic to friends and family.

CONCLUSIONS

This study applied Web-based and face-to-face components into a hybrid clinic and measured an overall positive experience with high patient satisfaction through a process evaluation. The findings support the potential of a hybrid clinic with synchronous and asynchronous modes of communication to be a scalable hearing health care model, addressing the needs of adults with hearing loss globally.

Smartphone Apps in the Context of Tinnitus: Systematic Review

Smartphones containing sophisticated high-end hardware and offering high computational capabilities at extremely manageable costs have become mainstream and an integral part of users' lives. Widespread adoption of smartphone devices has encouraged the development of many smartphone applications, resulting in a well-established ecosystem, which is easily discoverable and accessible via respective marketplaces of differing mobile platforms. These smartphone applications are no longer exclusively limited to entertainment purposes but are increasingly established in the scientific and medical field. In the context of tinnitus, the ringing in the ear, these smartphone apps range from relief, management, self-help, all the way to interfacing external sensors to better understand the phenomenon. In this paper, we aim to bring forth the smartphone applications in and around tinnitus. Based on the PRISMA guidelines, we systematically analyze and investigate the current state of smartphone apps, that are directly applied in the context of tinnitus. In particular, we explore Google Scholar, CiteSeerX, Microsoft Academics, Semantic Scholar for the identification of scientific contributions. Additionally, we search and explore Google's Play and Apple's App Stores to identify relevant smartphone apps and their respective properties. This review work gives (1) an up-to-date overview of existing apps, and (2) lists and discusses scientific literature pertaining to the smartphone apps used within the context of tinnitus.

Internet-Based Interventions for Adults With Hearing Loss, Tinnitus, and Vestibular Disorders: A Systematic Review and Meta-Analysis

Internet-based interventions have been developed to improve access to audiovestibular health care. This review aimed to identify outcomes of Internet interventions for adults with hearing loss, tinnitus, and vestibular disorders. Electronic databases and manual searches were performed to identify studies meeting eligibility for inclusion. Fifteen studies (1,811 participants) met the inclusion criteria, with nine studies targeting tinnitus distress, five considering hearing loss, and one for vestibular difficulties. Only the tinnitus and hearing loss Internet intervention studies were eligible for data synthesis. Internet-based interventions for hearing loss were diverse. Overall, they showed no significant effects, although a statistically significant moderate effect (d = 0.59) was found after removing the study with the highest risk of bias (as a result of high attrition). Most Internet-based interventions for tinnitus provided cognitive behavioural therapy. They yielded statistically significant mean effect sizes for reducing tinnitus distress compared with both inactive (d = 0.59) and active controls (d = 0.32). Significant effects were also present for the secondary outcomes of anxiety, depression, insomnia, and quality of life (combined effect d = 0.28). Only Internet-based interventions for tinnitus evaluated the 1-year postintervention effects indicated that results were maintained long term (d = 0.45). Scientific study quality was appraised using the Grading of Recommendations Assessment, Development and Evaluation approach and found to vary from very low to moderate. This review indicates the potential of Internet interventions for tinnitus to provide evidence-based accessible care. There is a need for additional high-quality evidence before conclusive results can be established regarding the effects of audiovestibular Internet interventions.
