The ICF core sets for hearing loss project: Functioning and disability from the patient perspective

Development of core sets for deafblindness: an international expert survey on functioning and disability of individuals living with deafblindness using the International Classification of Functioning, Disability, and Health

BACKGROUND

The development of International Classification of Functioning, Disability, and Health (ICF) Core Sets greatly enhances the global recognition of health conditions, thereby advancing research, education, and care provision. Aside from the work of researchers, and the viewpoint of persons with lived experience, the development of Core Sets for deafblindness needs to include the viewpoints of professionals with expertise unique to this condition.

AIM

To represent the perspective of health and social service expert professionals in the development of ICF Core Sets for deafblindness.

DESIGN

Cross-sectional cohort study.

SETTING

Global online survey representing all six regions of the World Health Organization.

POPULATION

One hundred and five professionals providing and health or social service to individuals living with deafblindness with a minimum of 2 years of work experience with this population.

METHODS

An online survey was distributed through professional networks and social media for individuals working with persons living with deafblindness. Demographic items were summarized using descriptive statistics. Six open-ended questions explored the perceptions of body functions and structures that influence activities and participation, as well as environmental and personal factors that facilitate functioning. Data were linked to the ICF codes using established linking rules and procedures.

RESULTS

The 2934 survey response units were linked using IFC categories. Of the 421 unique categories, 133 were used by 5% or more of respondents. Most categories within the Activities and Participation component were equally emphasized. The most frequent Environmental factors were support and relationships, services, systems, and policies, as well as and the physical environment (e.g., hearing aids or noise). Mental functions, including higher level cognitive functions, temperament and personality were frequently emphasized.

CONCLUSIONS

Almost three quarters (73.3%) of the entire ICF classification categories were included in the expert survey results. This proportion emphasizes the importance of a multidimensional tool, such as the ICF, for assessing functioning and health for persons with deafblindness.

CLINICAL REHABILITATION IMPACT

The representation of this professional perspective in Core Set development will improve standardized assessment and documentation, intervention planning, and facilitate interprofessional communication with the goal of improving person-centered care for persons living with deafblindness.

Psychometric evaluation of the 4C tinnitus management questionnaire for patients with tinnitus alone or tinnitus combined with hyperacusis

OBJECTIVE

To assess the psychometric properties of a new questionnaire evaluating patients' confidence in managing their tinnitus, the 4C tinnitus management questionnaire (4C), which was designed to be used in the process of cognitive behavioural therapy.

DESIGN

Retrospective cross-sectional based on patient records.

STUDY SAMPLES

99 consecutive patients who sought help for tinnitus (with or without hyperacusis) from an audiology clinic in the UK. Pure tone average (PTA) hearing thresholds, Uncomfortable Loudness Levels (ULLs), and responses to the 4C questionnaire, Tinnitus Handicap Inventory (THI), Hyperacusis Questionnaire (HQ), and Screening for Anxiety and Depression in Tinnitus (SAD-T) questionnaire were gathered from the records of patients held at the audiology department.

RESULTS

Cronbach's alpha for the 4C was 0.91, indicating high internal consistency. Exploratory factor analysis suggested a one-factor solution. Discriminant validity was supported by weak correlations between 4C scores and PTA across ears and ULLmin (the across-frequency average ULL for the ear with lower average ULL). Convergent validity was supported by moderate correlations between 4C scores and scores for the THI, HQ, and SAD-T.

CONCLUSIONS

The 4C is an internally consistent questionnaire with high convergent and discriminant validity, which can be used to assess patients' confidence in managing their tinnitus.

On the Feasibility of Using Behavioral Listening Effort Test Methods to Evaluate Auditory Performance in Cochlear Implant Users

Realistic outcome measures that reflect everyday hearing challenges are needed to assess hearing aid and cochlear implant (CI) fitting. Literature suggests that listening effort measures may be more sensitive to differences between hearing-device settings than established speech intelligibility measures when speech intelligibility is near maximum. Which method provides the most effective measurement of listening effort for this purpose is currently unclear. This study aimed to investigate the feasibility of two tests for measuring changes in listening effort in CI users due to signal-to-noise ratio (SNR) differences, as would arise from different hearing-device settings. By comparing the effect size of SNR differences on listening effort measures with test-retest differences, the study evaluated the suitability of these tests for clinical use. Nineteen CI users underwent two listening effort tests at two SNRs (+4 and +8 dB relative to individuals' 50% speech perception threshold). We employed dual-task paradigms-a sentence-final word identification and recall test (SWIRT) and a sentence verification test (SVT)-to assess listening effort at these two SNRs. Our results show a significant difference in listening effort between the SNRs for both test methods, although the effect size was comparable to the test-retest difference, and the sensitivity was not superior to speech intelligibility measures. Thus, the implementations of SVT and SWIRT used in this study are not suitable for clinical use to measure listening effort differences of this magnitude in individual CI users. However, they can be used in research involving CI users to analyze group data.

Hearing and Functioning in Everyday Life Questionnaire: Development and Validation of an ICF-Based Instrument

OBJECTIVES

Self-assessment instruments are commonly used in audiological rehabilitation. However, several studies highlight the lack of multidimensionality in existing outcome measures, with the consequence that they only partially capture aspects of functioning in everyday life for people living with hearing loss. This study aimed to develop and investigate the content validity of a self-assessment instrument based on the validated Brief International Classification of Functioning, Disability, and Health Core Set for Hearing Loss.

DESIGN

The design was a two-part instrument development study. The first part focused on the item-generation process of the instrument, named the Hearing and Functioning in Everyday Life Questionnaire (HFEQ) during an experts' workshop. The second part focused on international content validation of the instrument using group interviews. Strategic sampling was used and 30 adults with hearing loss from India, South Africa, and the United States participated in the group interviews.

RESULTS

The expert's workshop resulted in the first version of the HFEQ containing 30 items. The results from group interviews show that the content of the HFEQ was considered to be valid concerning its relevance, comprehensiveness, and comprehensibility. A majority (73%) of the HFEQ items were perceived by the participants as relevant and easy to comprehend. For the remaining 27% of the items, the content was perceived to be relevant in all countries, but some terms and expressions were reported to require rewording or clearer examples. These modifications will be made in the next step of the development process.

CONCLUSION

Content validation of the HFEQ demonstrates promising results, with participants perceiving the content as relevant and comprehensible. Further psychometric validation is required to investigate other psychometric properties, such as construct validity and reliability. The HFEQ has the potential to become a valuable new instrument for assessing everyday functioning in people with hearing loss in audiological rehabilitation and in research.

Exploring Factors That Contribute to the Success of Rehabilitation With Hearing Aids

OBJECTIVES

Hearing aids are an essential and important part of hearing rehabilitation. The combination of technical data on hearing aids and individual rehabilitation needs can give insight into the factors that contribute to the success of rehabilitation. This study sets out to investigate if different subgroups of (comparable) hearing aids lead to differences in the success of rehabilitation, and whether these differences vary between different domains of auditory functioning.

DESIGN

This study explored the advantages of including patient-reported outcome measures (PROMs) in the process of purchasing new hearing aids in a large sample of successful hearing aid users. Subject data were obtained from 64 (commercial) hearing aid dispensers and 10 (noncommercial) audiological centers in the Netherlands. The PROM was a 32-item questionnaire and was used to determine the success of rehabilitation using hearing aids by measuring auditory disability over time. The items were mapped on six domains of auditory functioning: detection, discrimination, localization, speech in quiet, speech in noise, and noise tolerance, encompassing a variety of daily-life listening situations. Hearing aids were grouped by means of cluster analysis, resulting in nine subgroups. In total, 1149 subjects were included in this study. A general linear model was used to model the final PROM results. Model results were analyzed via a multifactor Analysis of Variance. Post hoc analyses provided detailed information on model variables.

RESULTS

Results showed a strong statistically significant effect of hearing aids on self-perceived auditory functioning in general. Clinically relevant differences were found for auditory domains including detection, speech in quiet, speech in noise, and localization. There was only a small, but significant, effect of the different subgroups of hearing aids on the final PROM results, where no differences were found between the auditory domains. Minor differences were found between results obtained in commercial and noncommercial settings, or between novice and experienced users. Severity of Hearing loss, age, gender, and hearing aid style (i.e., behind-the-ear versus receiver-in-canal type) did not have a clinically relevant effect on the final PROM results.

CONCLUSIONS

The use of hearing aids has a large positive effect on self-perceived auditory functioning. There was however no salient effect of the different subgroups of hearing aids on the final PROM results, indicating that technical properties of hearing aids only play a limited role in this respect. This study challenges the belief that premium devices outperform basic ones, highlighting the need for personalized rehabilitation strategies and the importance of evaluating factors contributing to successful rehabilitation for clinical practice.

Burn Patient Perspectives on Disability Weights and the Philosophy of Disability: A Gap in the Literature

Background

Disability-adjusted life years (DALY) have a ubiquitous presence in academic global health, including attempts to understand the global burden of burn injuries.

Objective

The present scoping review aimed to examine whether disability weights (DWs) were informed by burn patient perspectives and secondarily to determine whether literature indicates which of the three most common philosophical models of disability best aligns with burn patient experiences.

Methods

A review of six databases was conducted and The Critical Appraisal Skills Program (CASP) checklist was utilized.

Results

Out of a total of 764 articles, zero studies solicited patient perspectives of DWs. Four articles contained data that could be extrapolated to patient perspectives on disability. All articles utilized semi-structured interviews of burn survivors and reported thematic elements including return to work, self-image, and social integration. Patients reported similar themes that burn injuries were disabling injuries and instrumentally detrimental, with modulation based on the patient's social circumstances.

Conclusions

This scoping review highlights a significant gap in literature. First, no studies were found directly investigating burn patient perspectives on burn DWs. Current DWs have been derived from expert opinions with limited input from patients. Second, the limited primary patient data gleaned from this review suggest patients consider their injuries as instrumentally detrimental, which aligns most closely with the welfarist view of disability. More explicit investigations into the philosophical model of disability best aligning with burn patient experiences are needed to ground the health economics of burns in sound theory.

Towards a Consensus on an ICF-Based Classification System for Horizontal Sound-Source Localization

The study aimed to develop a consensus classification system for the reporting of sound localization testing results, especially in the field of cochlear implantation. Against the background of an overview of the wide variations present in localization testing procedures and reporting metrics, a novel classification system was proposed to report localization errors according to the widely accepted International Classification of Functioning, Disability and Health (ICF) framework. The obtained HEARRING_LOC_ICF scale includes the ICF graded scale: 0 (no impairment), 1 (mild impairment), 2 (moderate impairment), 3 (severe impairment), and 4 (complete impairment). Improvement of comparability of localization results across institutes, localization testing setups, and listeners was demonstrated by applying the classification system retrospectively to data obtained from cohorts of normal-hearing and cochlear implant listeners at our institutes. The application of our classification system will help to facilitate multi-center studies, as well as allowing better meta-analyses of data, resulting in improved evidence-based practice in the field.

The development of a Self-Rated ICF-based questionnaire (HEAR-COMMAND Tool) to evaluate Hearing, Communication, and Conversation disability: Multinational experts' and patients' perspectives

Objective

An instrument that facilitates the advancement of hearing healthcare delivery from a biomedical model to a biopsychosocial one that underpins the International Classification of Functioning, Disability, and Health framework (ICF) brief and comprehensive Core Sets for Hearing Loss (CSHL) is currently unavailable. The objective is to describe the process of developing and validating a new questionnaire named the HEAR-COMMAND Tool created by transferring the ICF CSHL into a theory-supported, practically manageable concept.

Design

A team from Germany, the USA, the Netherlands, and Egypt collaborated on development. The following ICF domains were considered; "Body Functions" (BF), "Activities and Participation" (AP), and "Environmental Factors" (EF). The development yielded English, German, and Arabic versions. A pilot validation study with a total of 109 respondents across three countries, Germany, Egypt, and the USA was conducted to revise the item terminology according to the feedback provided by the respondents.

Results

The questionnaire included a total of 120 items. Ninety items were designed to collect information on the functioning and 30 items inquiring about demographic information, hearing status, and Personal Factors. Except for the "Body Structures" (BS) domain, all the categories of the brief ICF CSHL were covered (a total of 85% of the categories). Moreover, the items covered 44% of the comprehensive ICF CSHL categories including 73% of BF, 55% of AP, and 27% of EF domains. Overall, the terminology of 24 ICF-based items was revised based on the qualitative analysis of the respondents' feedback to further clarify the items that were found tod be unclear or misleading. The tool highlighted the broad connection of HL with bodily health and contextual factors.

Conclusions

The HEAR-COMMAND Tool was developed based on the ICF CSHL and from multinational experts' and patients' perspectives with the aim to improve the execution of audiological services, treatment, and rehabilitation for adult patients with HL. Additional validation of the tool is ongoing. The next step would be to pair the tool with BS categories since it was excluded from the tool and determine its effectiveness in guiding hearing health care practitioners to holistically classify categories influencing hearing, communication, and conversation disability.

Perceived listening ability and hearing loss: Systematic review and qualitative meta-synthesis

BACKGROUND

Hearing loss (HL) can affect communication in complex ways. Understanding how adults with HL reflect on and conceptualise the way they listen (metacognition) is required if interventions, and the outcome measures used to evaluate them, are to address barriers to functional communication arising from HL.

OBJECTIVES

This study describes how adults with HL experience and report the processes, behaviours, and components of listening, as presented in published studies.

DESIGN

Systematic review and meta-synthesis of qualitative studies.

METHODS

Systematic searches identified English-language, peer-reviewed journal articles reporting the results of qualitative or mixed-methods studies of adults' with HL perceived listening abilities. Medline, PsychInfo, Web of Science, Embase, and Google Scholar were searched from inception to November 2021. Handsearching reference lists of included studies identified additional studies for inclusion. The Critical Appraisal Skills Programme (CASP) qualitative checklist was used to appraise studies' methodological quality. Data from included studies were analysed using thematic meta-synthesis. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) Confidence in the Evidence from Reviews of QUALitative (CERQual) approach assessed confidence in the review findings. Two reviewers independently completed all screening and quality appraisal. Thematic meta-synthesis and GRADE CERQual assessment was completed by one reviewer and confirmed by a second reviewer. Discrepancies were resolved through discussion.

RESULTS

Data from 46 studies were included in the review. Thematic meta-synthesis identified six descriptive themes: 1) perceived listening ability; 2) external modifiers; 3) psychosocial impacts of hearing loss; 4) communication partner perspectives; 5) self-efficacy for listening; and 6) cognitive load. GRADE CERQual ratings for descriptive themes ranged from low to moderate confidence. Descriptive themes were related by analytic themes of liminality and reciprocity.

CONCLUSIONS

Adults with HL provide in-depth accounts of components and processes of listening, with studies reporting both cognitive and affective experiences consistent with theoretical models of metacognition. The findings will inform content generation for a hearing-specific patient-reported outcome measure of perceived listening ability in everyday communication.

Development and Utility of an International Classification of Functioning, Disability and Health Code Set for Younger-Old Adults With Fall Risk: Implications for Audiologists

Purpose:

Falling is a multifactorial condition that can cause severe injury and even death in older adults. Early identification of fall risk factors, as the first step of preventive health care, can assist in reducing the negative and often debilitating effects of falls in older adults. By using the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework to develop an ICF code set to identify fall risk factors in older adults, health care practitioners could obtain health information in a multidimensional way.

Method:

This study describes the final phase of a comprehensive, three-phase, mixed-methods sequential study. For this third phase, a pre–post group design that focused on the audiologist's perceptions of the clinical utility of a newly developed ICF code set was employed. The questionnaire that was used for this purpose consisted of two distinct sections: clinical application and clinical utility (viz., appropriateness, accessibility, practicability, acceptability, and professional utility). Thirty practicing audiologists participated in the study. Data were analyzed for each of the two sections of the questionnaire.

Results:

Results related to clinical application indicated that regardless of the audiologists' experience in routine fall risk assessment or fall risk factor identification, the use of the developed ICF code set increased their ability to correctly identify relevant clinical aspects. Results related to clinical utility showed high scores across all five measure components, with the highest clinical utility component being acceptability, closely followed by appropriateness and professional utility, and the lowest being accessibility.

Conclusion:

Several clinical implications have emerged from this study, including the usefulness of the ICF code set to identify and document fall risk factors in older adults, the code set's ability to guide audiologists to determine individualized assessment needs either by themselves or by other health care disciplines, and that the code set could be used by audiologists regardless of their experience in vestibular assessments.

Psychometric Evaluation of the Hyperacusis Impact Questionnaire (HIQ) and Sound Sensitivity Symptoms Questionnaire (SSSQ) Using a Clinical Population of Adult Patients with Tinnitus Alone or Combined with Hyperacusis

BACKGROUND

Hyperacusis can be defined as an intolerance of certain everyday sounds, which are perceived as too loud or uncomfortable and which cause significant distress and impairment in the individual's day-to-day activities. It is important to assess symptoms of sound intolerance and their impact on the patient's life, so as to evaluate the need for treatment and to assess the effectiveness of treatments.

PURPOSE

The aim was to evaluate the psychometric properties of the Hyperacusis Impact Questionnaire (HIQ), and the Sound Sensitivity Symptoms Questionnaire (SSSQ). The 8-item HIQ focuses on assessing the impact of hyperacusis on the patient, while the 5-item SSSQ is designed to assess the type and severity of sound intolerance symptoms.

RESEARCH DESIGN

This was a retrospective cross-sectional study.

STUDY SAMPLE

In total, 266 consecutive patients who attended a Tinnitus and Hyperacusis Therapy Clinic in the United Kingdom within a 6-month period. Fifty-five percent were female. The average age was 54 years (standard deviation = 16 years).

DATA COLLECTION AND ANALYSIS

Data were collected retrospectively from the records of patients held at the audiology department. Audiological measures were pure-tone audiometry and Uncomfortable Loudness Levels (ULLs). Questionnaires administered in addition to the HIQ and SSSQ were: Tinnitus Handicap Inventory, Hyperacusis Questionnaire (HQ), and Screening for Anxiety and Depression in Tinnitus.

RESULTS

Exploratory factor analysis suggested one-factor solutions for both the HIQ and SSSQ. Multiple-causes multiple-indicators (MIMIC) models showed some small influences of gender but negligible effects of age for both the HIQ and SSSQ. Receiver Operating Characteristic (ROC) analysis showed no significant effects of covariates on the ROC curves. Cronbach's α was 0.93 for the HIQ, and 0.87 for the SSSQ, indicating high internal consistency. Convergent validity was supported by moderate correlations between HQ and HIQ scores and between SSSQ scores and ULLs.

CONCLUSION

The HIQ and SSSQ are internally consistent questionnaires that can be used in clinical and research settings.

Enhancing Person-Centered Audiologic Rehabilitation: Exploring the Use of an Interview Tool Based on the International Classification of Functioning, Disability, and Health Core Sets for Hearing Loss

Health care interventions that are intended to improve hearing should be based on the results of individual patient assessments. To improve these assessments, the feasibility of an International Classification of Functioning, Disability, and Health (ICF)-based interview tool was tested in a single clinical setting in Sweden. Audiologists participating in the study used the interview tool during a four-week testing period and provided written reflections after each session. The use of this tool was also evaluated in a focus group interview that took place after the completion of the project. The results of this study identified both process-related and structure-related factors that were highly relevant to the implementation of this interview tool. Overall, the findings revealed that the use of this interview tool promoted person-centered care in encounters focused on clinical audiological rehabilitation. Specifically, the ICF-based holistic approach permitted the audiologists to acquire more comprehensive patient narratives. The use of the ICF interview tool facilitated patient participation and permitted the audiologist to collect more substantial and meaningful information from each patient.

Conformities and gaps of clinical audiological data with the international classification of functioning disability and health core sets for hearing loss

OBJECTIVE

The International Classification of Functioning Disability and Health (ICF) is a classification of health and health-related domains created by the World Health Organization and can be used as a standard to evaluate the health and disability of individuals. The ICF Core Set for Hearing Loss (CSHL) refers to the ICF categories found to be relative to Hearing Loss (HL) and the consequences of it on daily life. This study aimed to adapt the content of a database gathered in Hörzentrum Oldenburg gGmbH that included HL medical assessments and audiological data to the ICF.

DESIGN

ICF linking rules were applied to these assessment methods including medical interviews, ear examinations, pure-tone audiometry, Adaptive Categorical Loudness Scaling, and speech intelligibility test.

STUDY SAMPLE

1316 subjects.

RESULTS

In total, 44% of the brief and 18% of the comprehensive CSHL categories were addressed. The hearing functions were broadly evaluated. "Activities and Participation" and "Environmental Factors" were poorly examined (17% and 12% of the comprehensive CSHL categories, respectively).

CONCLUSIONS

The HL correlation with day-to-day activities limitation, performance restriction, and environmental conditions were poorly addressed. This study showed the essence of incorporating these methodologies with approaches that assess the daily-life challenges caused by HL in rehabilitation.

Evaluating the Revised Work Rehabilitation Questionnaire in Cochlear Implant Users Cochlear Implant Outcome Assessment Based on the International Classification of Functioning, Disability, and Health (ICF)

OBJECTIVES

The 59-item Work Rehabilitation Questionnaire (WORQ) was developed based on the International Classification of Functioning, Disability and Health (ICF) core set for vocational rehabilitation to assess work related functioning. It was revised to include 17 questions, assigned to 14 ICF categories relevant to cochlear implant (CI) users. This cross-sectional multicenter study aimed to evaluate CI users' responses on the WORQ questions to describe and generate ICF qualifiers for the revised WORQ in CI users, forming part of a broader framework of CI outcome measures linked to the ICF.

METHODS

One hundred seventy-seven adults over the age of 18 years with a minimum of one year's device experience were included in the analysis. The WORQ was completed by the participants at a routine visit to the clinic, via email, or via post.

RESULTS

Most of the CI users perceived no problem on the WORQ questions (53.7%-91%), finished secondary school (54.2%) or obtained a college or university degree (32.8%) and are either employed (41.2%) or retired (34.5%). CI users that are currently working mostly have a full-time position (34.5%). Subjects reported no problem (91%) with sensation of falling, while handling communication devices and techniques (10.9%) and tinnitus (9.6%) showed the highest number of subjects reporting a complete problem.

CONCLUSIONS

Overall, most of the CI users experienced no impairment, restriction or limitation on the WORQ questions and their assigned ICF categories. Their education level resembles the education level of the general population and they seem to integrate or reintegrate well in professional life postoperatively.

Defining a Patient-Centred Core Outcome Domain Set for the Assessment of Hearing Rehabilitation With Clients and Professionals

Background

A variety of outcome domains are currently measured for the assessment of hearing rehabilitation. To date, there is no consensus about which outcome domains should be measured, when they should be measured, and how they should be measured. In addition, most studies seeking to develop core outcome sets and measures for hearing rehabilitation services have primarily focussed on the opinions and expertise of researchers, and, to a lesser extent, clinicians, rather than also involving clients of those services. The principles of experience-based co-design suggest that health services, researchers, and policymakers should come together with clients and their families to design health services and define what metrics should be used for their success.

Objectives

This study aimed to seek views and consensus from a range of key stakeholders to define which client-centred self-report outcome domains should be measured, when they should be measured, and how they should be measured, in a national publicly funded hearing rehabilitation scheme. In addition, the study aimed to identify current and future potential mechanisms and systems to standardise the collection of data and reporting of outcomes, to enable comparison across clients and hearing service providers.

Methods

Two stakeholder groups participated in a three-round online Delphi process: (1) 79 professional stakeholders involved in the delivery of hearing services in Australia, and (2) 64 hearing rehabilitation services’ clients identified by not-for-profit consumer organisations. An initial set of in-person workshops scoped the key issues upon which to develop the initial open-ended questions and subsequent Likert-scale statements addressing these issues. These statements were then distributed to both groups in an online survey. The respondent ratings were summarised, and the summary was returned to respondents along with a second round of the survey. This process was then repeated once more. The five most important outcome domains from both groups were then combined, and a consensus workshop of seven professionals and three client advocates agreed on the top four ranked domains.

Results

A range of potential outcome domains were identified as relevant indicators of successful hearing rehabilitation. Communication ability, personal relationships, wellbeing, and participation restrictions were identified as a core outcome domain set that should be measured as a minimum for patients receiving hearing rehabilitation. There was little agreement on the preferred timepoints for collection of outcome measures, with respondents expressing the view that this should be established by research once a set of outcome measures has been selected. However, there was broad agreement that measurements of these domains should be collected at baseline (before the provision of hearing rehabilitation) and no earlier than 3 months following the completion of rehabilitation. Potential benefits and issues with the development of a national outcomes database/collection system were also identified and prioritised, with participants highlighting the importance of valid, high-quality, trustworthy, and comprehensive data collection.

Conclusion

These results provide a Core Outcome Domain Set for the self-reported evaluation of hearing rehabilitation and provide important background information for the design of methods to implement them across hearing healthcare systems. However, the wide range of outcome domains identified as potentially providing important additional information and the lack of specific measures to address these domains strongly suggest that there is still more research to be done. Ongoing stakeholder engagement will continue to be vital for future implementation. In addition, further research is required to determine the optimal time following hearing rehabilitation to utilise any particular outcome measure.

Cochlear implant aesthetics and its impact on stigma, social interaction and quality of life: a mixed-methods study protocol

INTRODUCTION

Awareness of the benefits of cochlear implants is low, and barriers such as fear of surgery and ongoing rehabilitation have been noted. Perceived stigma associated with hearing loss also plays a key role, with many adults not wanting to appear old or be identified as a person with a disability. In effect, a cochlear implant makes deafness visible. New technologies have led to a smaller external profile for some types of cochlear implants, but qualitative assessments of benefit have not been explored. This study will examine cochlear implant aesthetics and cosmetics, and its impact on perceived stigma, social interactions, communication and quality of life. A particular focus will be the examination of totally implantable device concepts. A secondary aim is to understand what research techniques are best suited and most appealing for cochlear implant recipients, to assist in future study design and data collection methods.

METHODS AND ANALYSIS

This study utilises a mixed-methods design. Three datasets will be collected from each participant with an expected sample size of 10-15 participants to allow for data saturation of themes elicited. Each participant will complete a demographic questionnaire, a quickfire survey (a short concise questionnaire on a topic of research familiarity and preference) and a semi-structured interview. Questionnaire and quickfire survey data will be analysed using descriptive statistics. Interviews will be transcribed and analysed thematically. All participants will be adults with more than 1 year of experience using cochlear implants.

ETHICS AND DISSEMINATION

This study has been granted ethical approval from Macquarie University (HREC: 520211056232432) and meets the requirements set out in the National Statement on Ethical Conduct in Human Research. Study findings will be disseminated widely through international peer-reviewed journal articles, public and academic presentations, plain language summaries for participants and an executive summary for the project funder. This work was supported by Cochlear Limited (Cochlear Ltd). The funder will have no role in conducting or reporting on the study.

Examining the consequences of tinnitus using the multidimensional perspective

BACKGROUND

Tinnitus is one of the most frequent chronic conditions in adults with wide range of consequences.

AIMS/OBJECTIVES

The aim of the current study was to determine the problems and life effects reported by individuals with tinnitus using the International Classification of Functioning, Disability and Health (ICF) framework.

MATERIAL AND METHODS

The study used a cross-sectional survey design. A total of 344 individuals with tinnitus completed a series of questionnaires. The responses to open-ended questions were linked to ICF categories.

RESULTS

Activity limitations and participation restrictions were most dominant consequence of tinnitus followed by effect on the body function with limited emphasis on the contextual factors. Frequently reported responses to body function involved emotional functions (b152), attention function (b140), and sleep functions (b134). Commonly reported responses to activity limitations and participation restrictions were recreation and leisure (d920), conversation (d350), communicating with-receiving-spoken messages (d310), listening (d115), and remunerative employment (d850). Sound intensity (e2500) and sound quality (e2501) were the frequently reported responses to environmental factors. Coping styles, past and present experiences, and lifestyle were the most frequently occurring personal factors.

CONCLUSIONS AND SIGNIFICANCE

The study highlighted some key influencing factors of tinnitus in different ICF domains which can be helpful in rehabilitation planning.

Community-Based Participatory Research and Human-Centered Design Principles to Advance Hearing Health Equity

OBJECTIVES

Inclusive and equitable research is an ethical imperative. Community-based participatory research (CBPR) as well as human-centered design are approaches that center partnership between community members and academic researchers. Together, academic-community research teams iteratively study community priorities, collaboratively develop ethical study designs, and co-create innovations that are accessible and meaningful to the community partners while advancing science. The foundation of the CBPR approach is reliant on its core principles of equity, colearning, shared power in decision-making, reciprocity, and mutual benefit. While the CBPR approach has been used extensively in public health and other areas of healthcare research, the approach is relatively new to audiology, otolaryngology, and hearing health research. The purpose of the present article is to advance an understanding of the CBPR approach, along with principles from human-centered design, in the context of research aimed to advance equity and access in hearing healthcare.

DESIGN

The literature is reviewed to provide an introduction for auditory scientists to the CBPR approach and human-centered design, including discussion of the underlying principles of CBPR and where it fits along a community-engaged continuum, theoretical and evaluation frameworks, as well as applications within auditory research.

RESULTS

Recent applications of CBPR have been framed broadly within the theoretical positions of the socioecological model for a systems-level approach to community-engaged research and the Health Services Utilization model within health services and disparities research using CBPR. Utilizing human-centered design strategies can work in tandem with a CBPR approach to engage a wide range of people in the research process and move toward the development of innovative yet feasible solutions.

CONCLUSIONS

Leveraging the principles of CBPR is an intricate and dynamic process, may not be a fit for some topics, some researchers' skillsets, and may be beyond some projects' resources. When implemented skillfully and authentically, CBPR can be of benefit by elevating and empowering community voices and cultural perspectives historically marginalized in society and underrepresented within research. With a focus on health equity, this review of CBPR in the study of hearing healthcare emphasizes how this approach to research can help to advance inclusion, diversity, and access to innovation.

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.

Cogmed Training Does Not Generalize to Real-World Benefits for Adult Hearing Aid Users: Results of a Blinded, Active-Controlled Randomized Trial

Objectives:

Performance on working memory tasks is positively associated with speech-in-noise perception performance, particularly where auditory inputs are degraded. It is suggested that interventions designed to improve working memory capacity may improve domain-general working memory performance for people with hearing loss, to benefit their real-world listening. We examined whether a 5-week training program that primarily targets the storage component of working memory (Cogmed RM, adaptive) could improve cognition, speech-in-noise perception and self-reported hearing in a randomized controlled trial of adult hearing aid users with mild to moderate hearing loss, compared with an active control (Cogmed RM, nonadaptive) group of adults from the same population.

Design:

A preregistered randomized controlled trial of 57 adult hearing aid users (n = 27 experimental, n = 30 active control), recruited from a dedicated database of research volunteers, examined on-task learning and generalized improvements in measures of trained and untrained cognition, untrained speech-in-noise perception and self-reported hearing abilities, pre- to post-training. Participants and the outcome assessor were both blinded to intervention allocation. Retention of training-related improvements was examined at a 6-month follow-up assessment.

Results:

Per-protocol analyses showed improvements in trained tasks (Cogmed Index Improvement) that transferred to improvements in a trained working memory task tested outside of the training software (Backward Digit Span) and a small improvement in self-reported hearing ability (Glasgow Hearing Aid Benefit Profile, Initial Disability subscale). Both of these improvements were maintained 6-month post-training. There was no transfer of learning shown to untrained measures of cognition (working memory or attention), speech-in-noise perception, or self-reported hearing in everyday life. An assessment of individual differences showed that participants with better baseline working memory performance achieved greater learning on the trained tasks. Post-training performance for untrained outcomes was largely predicted by individuals’ pretraining performance on those measures.

Conclusions:

Despite significant on-task learning, generalized improvements of working memory training in this trial were limited to (a) improvements for a trained working memory task tested outside of the training software and (b) a small improvement in self-reported hearing ability for those in the experimental group, compared with active controls. We found no evidence to suggest that training which primarily targets storage aspects of working memory can result in domain-general improvements that benefit everyday communication for adult hearing aid users. These findings are consistent with a significant body of evidence showing that Cogmed training only improves performance for tasks that resemble Cogmed training. Future research should focus on the benefits of interventions that enhance cognition in the context in which it is employed within everyday communication, such as training that targets dynamic aspects of cognitive control important for successful speech-in-noise perception.

Operationalization of the Brief ICF Core Set for Hearing Loss: An ICF-Based e-Intake Tool in Clinical Otology and Audiology Practice

OBJECTIVES

According to the International Classification of Functioning, Disability and Health (ICF), functioning reflects the interplay between an individual's body structures and functions, activities, participation, environmental, and personal factors. To be useful in clinical practice, these concepts need to be operationalized into a practical and integral instrument. The Brief ICF Core Set for Hearing Loss (CSHL) provides a minimum standard for the assessment of functioning in adults with hearing loss. The objective of the present study was to operationalize the Brief CSHL into a digital intake tool that could be used in the otology-audiology practice for adults with ear and hearing problems as part of their intake assessment.

DESIGN

A three-step approach was followed: (1) Selecting and formulating questionnaire items and response formats, using the 27 categories of the Brief CSHL as a basis. Additional categories were selected based on relevant literature and clinical expertise. Items were selected from existing, commonly used disease-specific questionnaires, generic questionnaires, or the WHO's official descriptions of ICF categories. The response format was based on the existing item's response categories or on the ICF qualifiers. (2) Carrying out an expert survey and a pilot study (using the three-step test interview. Relevant stakeholders and patients were asked to comment on the relevance, comprehensiveness, and comprehensibility of the items. Results were discussed in the project group, and items were modified based on consensus. (3) Integration of the intake tool into a computer-based system for use in clinical routine.

RESULTS

The Brief CSHL was operationalized into 62 items, clustered into six domains: (1) general information, including reason for visit, sociodemographic, and medical background; (2) general body functions; (3) ear and hearing structures and functions; (4) activities and participation (A&P); (5) environmental factors (EF); and (6) personal factors (mastery and coping). Based on stakeholders' responses, the instructions of the items on A&P and EF were adapted. The three-step test interview showed that the tool had sufficient content validity but that some items on EF were redundant. Overall, the stakeholders and patients indicated that the intake tool was relevant and had a logical and clear structure. The tool was integrated in an online portal.

CONCLUSIONS

In the current study, an ICF-based e-intake tool was developed that aims to screen self-reported functioning problems in adults with an ear/hearing problem. The relevance, comprehensiveness, and comprehensibility of the originally proposed item list was supported, although the stakeholder and patient feedback resulted into some changes of the tool on item-level. Ultimately, the functioning information obtained with the tool could be used to promote patient-centered ear and hearing care taking a biopsychosocial perspective into account.

Musicians' Hearing Handicap Index: A New Questionnaire to Assess the Impact of Hearing Impairment in Musicians and Other Music Professionals

Purpose We aimed to develop and validate the Musicians' Hearing Handicap Index (MHHI), a new self-evaluation tool for quantifying occupation-related auditory difficulties in music professionals. Although pure-tone audiometry is often considered the "gold standard" and is usually employed as the main instrument for hearing assessment, it cannot fully describe the impact of hearing dysfunction. The MHHI is an attempt to complement the hearing impairment assessment toolbox and is based on a unique approach to quantify the effects of hearing-related symptoms or hearing loss on the performance of musicians and other music industry professionals. Method An initial set of 143 questionnaire items was successively refined through a series of critical appraisals, modifications, and suggestions. This yielded an intermediate questionnaire consisting of 43 items, which was administered to 204 musicians and sound engineers. After exploratory factor analysis, the final form of the MHHI questionnaire was obtained, consisting of 29 items. The questionnaire's test-retest reliability, internal consistency, discriminating power, content validity, criterion validity, and aspects of construct validity and inherent conceptual structure were assessed. Results Exploratory factor analysis revealed a combination of four common factors for the 29 validated questionnaire items. They were named "impact on social and working lives," "difficulties in performance and sound perception," "communication difficulties," and "emotional distress." The MHHI was shown to be a valid and reliable instrument to assess musicians' and sound engineers' occupational difficulties due to hearing impairment and related symptoms. Conclusion The ability of the MHHI to discriminate between groups of music professionals with different auditory symptoms or pure-tone audiometry thresholds suggests that auditory symptoms might influence a professional's performance to an extent that cannot be assessed by a pure-tone audiogram.

Validation of the Brief International Classification of Functioning, Disability and Health (ICF) core set for hearing loss: an international multicentre study

OBJECTIVE

Hearing loss (HL) affects the everyday functioning of millions of people worldwide. The Brief International Classification of Functioning Disability and Health (ICF) core sets for HL was developed to meet the complex health care needs of adults with HL. Because the brief core set for HL has not yet been validated internationally, this study aimed to investigate its validity from an international perspective.

DESIGN

A cross-sectional validation study based on data from structured interviews with adults with HL.

STUDY SAMPLE

Participants (n = 571) from India, South Africa, Sweden and the US were included.

RESULTS

A six-factor solution explained 71% of the variance, focussing on issues related to communication, the social environment, participation in society, health care services, support, relationships and emotions (α = 0.915). Three ICF categories demonstrated low reliability - temperament and personality functions, seeing functions and school education.

CONCLUSION

The Brief ICF core set for HL is valid for adults with HL internationally. However, to further increase its international validity, we recommend adding the categories d920 recreation and leisure and replacing d850 school education with the more inclusive block, d810-d839 education.

Adaptation of the Arabic versions of the Hearing Handicap Inventory for adults and elderly with permanent sensorineural hearing loss

Objective: To translate the Hearing Handicap Inventory for Adults (HHIA) and Hearing Handicap Inventory for the Elderly (HHIE) into Arabic while ensuring that the reliability and validity are the same as those of the original English versions.Design: Descriptive, cross-sectional study.Study sample: In total, 115 individuals with hearing impairment and 114 controls with normal hearing completed the Arabic versions of HHIA/HHIE. Each subject underwent a complete audiological evaluation before answering the questionnaires. The construct and discriminant validities were determined in addition to the reliability, which was investigated by calculating the internal and test-retest consistencies.Results: Internal consistency between the total and subscale scores were excellent for the Arabic versions of HHIA and HHIE (Cronbach's alpha: ∼0.90). With regard to the test-retest reproducibility, the Spearman's correlation coefficient for consistency between total scores obtained at baseline and those obtained at 6 weeks was acceptable (r = 0.761, p < 0.0001). The total scores were statistically proportional to the degree of hearing loss. Moreover, the questionnaire successfully differentiated between individuals with hearing impairment and those with normal hearing.Conclusions: Our findings clarified that the Arabic versions of HHIA and HHIE are acceptable tools for evaluating the psychological influences of hearing loss in Arabic populations.

How Do We Know That Our Patients Have Benefitted From Our ENT/Audiological Interventions? Presented at the Annual Meeting of ADANO 2016 in Berlin

: This short review article gives an introduction to some of the fundamental concepts and challenges facing measurement in hearing healthcare practice and research. The impact of hearing loss almost always extends beyond the sensory impairment itself, even when the measured degree of audiometric loss is mild. Yet, going beyond audibility, into the realm of measuring impact, takes us into a much more complex and less well-defined space. How does one therefore best measure the therapeutic benefit for evaluating efficacy or for clinical practice audit? Three case studies illustrate approaches to overcome such challenges. Each example highlights the importance of thinking critically about what it is one is seeking trying to measure, rather than selecting a questionnaire instrument based simply on its popularity or accessibility. We conclude by highlighting the important role that clinicians can play in collecting clinical data about their preferred instruments so that we have some evidence to inform decisions about good practice (content validity etc.). We would also strongly support open data sharing as we think that this is one of the best ways to make the most rapid progress the field.

Hear–Communicate–Remember: Feasibility of delivering an integrated intervention for family caregivers of people with dementia and hearing impairment via telehealth

Purpose

To evaluate the feasibility of Hear–Communicate–Remember, a training programme developed for family caregivers of people with dementia and hearing impairment that integrated hearing, communication and memory strategies, which was intended to be delivered via telehealth.

Materials and methods

Participants included six dyads consisting of adults with dementia and hearing impairment and their family caregivers. Data collection involved a combination of semi-structured interviews, self-report questionnaires and field notes.

Results

Analysis of the qualitative interviews revealed four themes: appropriateness of intervention resources, considerations for the delivery of intervention via telehealth, knowledge and application of intervention strategies, and impact of the intervention on day-to-day life. Results from the satisfaction survey indicated that caregiver participants were mostly satisfied with all aspects of the intervention except the use of some technological components. The field notes described challenges with implementation via telehealth.

Conclusions

Future research involving a cohort comparison study with a larger cohort of dyads is needed to establish treatment efficacy.

Coping with age-related hearing loss: patient-caregiver dyad effects on quality of life

BACKGROUND AND AIMS

Patients with age -related hearing loss (ARHL) and their natural caregivers have to confront a disability that produces progressive lifestyle changes. There is an interest in studying the ability of patients and their caregivers to cope with the difficulties that affect quality of life (QoL). In a sample of patient-caregiver dyads in the specific context of ARHL, we examine whether the QoL of patients and caregivers is influenced by the coping processes they use from a specific actor-partner interdependence model (APIM).

METHODS

This cross-sectional study involved dyads with patients having a diagnosis of ARHL. The self-reported data included QoL (WHOQoL-BREF) and coping strategies (BriefCope). The APIM was used to test the dyadic effects of coping strategies on QoL.

RESULTS

A total of 448 dyads were included; the patients and caregivers were love partners for 59% of the dyads. Coping strategies, such as social support, avoidance, problem solving, and positive thinking, exhibited evidence of actor effects (degree to which the individual's coping strategies are associated with their own QoL). Effects on the partner (degree to which the individual's coping strategies are associated with the QoL of the other member of the dyad) were found, i.e., when the patients mobilized their coping strategy based on social support and problem-solving, their caregivers reported higher environmental QoL.

CONCLUSION

This study emphasizes that the QoL for patients and their caregivers was directly related to the coping strategies they used. This finding suggests that targeted interventions should be offered to help patients and their relatives to implement more effective coping strategies.

Hearing loss and quality of life

OBJECTIVE

We sought to identify multidimensional factors associated with health-related quality of life (HRQoL) for use in developing an inventory in which HRQoL is a core concept in evaluating the impact of hearing loss and the efficacy of rehabilitative interventions.

METHOD

A qualitative approach was used in which we posed two major questions to a focus group consisting of eight adults with self-reported, bilateral sensorineural hearing loss of varying degrees. In essence, those questions were: (1) How do you define quality of life?, and (2) Can you describe specific incidents in your everyday life in which your hearing loss has impacted your quality of life? The discussion was embedded within a framework that utilized a modification of the Critical Incident Technique (CIT). We used well-established analytic techniques to translate the data into unitized thought units, which we coded into meaningful categories. Response frequency was used to determine the salience of responses in addressing the research questions.

RESULTS

Participants defined QoL in terms of a number of primary dimensions, most of which were directly or indirectly associated with specific recalled incidents in which those dimensions have played a notable role in contributing to their QoL.

CONCLUSIONS

The use of well-established methods to gather and analyze qualitative data generated by self-report techniques offers a promising direction for developing a standardized inventory for identifying the factors that impact QoL for persons with hearing loss and for evaluating the success of intervention strategies aimed at improving their HRQoL.

A Data-Driven Synthesis of Research Evidence for Domains of Hearing Loss, as Reported by Adults With Hearing Loss and Their Communication Partners

A number of assessment tools exist to evaluate the impact of hearing loss, with little consensus among researchers as to either preference or psychometric adequacy. The item content of hearing loss assessment tools should seek to capture the impact of hearing loss on everyday life, but to date no one has synthesized the range of hearing loss complaints from the perspectives of the person with hearing loss and their communication partner. The current review aims to synthesize the evidence on person with hearing loss- and communication partner-reported complaints of hearing loss. Searches were conducted in Cos Conference Papers Index, the Cumulative Index to Nursing and Allied Health Literature, Excerpta Medica Database, PubMed, Web of Science, and Google Scholar to identify publications from May 1982 to August 2015. A manual search of four relevant journals updated the search to May 2017. Of the 9,516 titles identified, 78 records (comprising 20,306 participants) met inclusion criteria and were taken through to data collection. Data were analyzed using meta-ethnography to form domains representing the person with hearing loss- and communication partner-reported complaints of hearing loss as reported in research. Domains and subdomains mutual to both perspectives are related to “Auditory” (listening, communicating, and speaking), “Social” (relationships, isolation, social life, occupational, and interventions), and “Self” (effort and fatigue, emotions, identity, and stigma). Our framework contributes fundamental new knowledge and a unique resource that enables researchers and clinicians to consider the broader impacts of hearing loss. Our findings can also be used to guide questions during diagnostic assessment and to evaluate existing measures of hearing loss.

An international qualitative study of functioning in autism spectrum disorder using the World Health Organization international classification of functioning, disability and health framework

This is the third in a series of four empirical studies designed to develop International Classification of Functioning, Disability and Health (ICF) Core Sets for Autism Spectrum Disorder (ASD). The present study aimed to describe functioning in ASD (as operationalized by the ICF) derived from the perspectives of diagnosed individuals, family members, and professionals. A qualitative study using focus groups and semi-structured interviews were conducted with 19 stakeholder groups (N = 90) from Canada, India, Saudi Arabia, South Africa, and Sweden. Meaningful concepts from the focus groups and individual interviews were linked to ICF categories using a deductive qualitative approach with standardized linking procedures. The deductive qualitative content analysis yielded meaningful functioning concepts that were linked to 110 ICF categories across all four ICF components. Broad variation of environmental factors and activities and participation categories were identified in this study, while body functions consisted mainly of mental functions. Body structures were sparsely mentioned by the participants. Positive aspects of ASD included honesty, attention to detail, and memory. The experiences provided by international stakeholders support the need to understand individuals with ASD in a broader perspective, extending beyond diagnostic criteria into many areas of functioning and environmental domains. This study is part of a larger systematic effort that will provide the basis to define ICF Core Sets for ASD, from which assessment tools can be generated for use in clinical practice, research, and health care policy making. Autism Res 2018, 11: 463-475. © 2017 The Authors Autism Research published by International Society for Autism Research and Wiley Periodicals, Inc.

LAY SUMMARY

The study findings support the need to understand the living experiences of individuals with Autism Spectrum Disorder (ASD) from a broader perspective, taking into account many areas of an individual's functioning and environment. The ICF can serve as foundation for exploring these living experiences more extensively by offering tools that enable wide variety of individual difficulties and strengths to be captured along with important environmental influences. As such, these tools can facilitate interventions that meet the needs and goals of the individual.

An international qualitative study of ability and disability in ADHD using the WHO-ICF framework

This is the third in a series of four cross-cultural empirical studies designed to develop International Classification of Functioning, Disability and Health (ICF, and Children and Youth version, ICF(-CY) Core Sets for Attention-Deficit Hyperactivity Disorder (ADHD). To explore the perspectives of individuals diagnosed with ADHD, self-advocates, immediate family members and professional caregivers on relevant areas of impairment and functional abilities typical for ADHD across the lifespan as operationalized by the ICF(-CY). A qualitative study using focus group discussions or semi-structured interviews of 76 participants, divided into 16 stakeholder groups. Participants from five countries (Brazil, India, Saudi Arabia, South Africa and Sweden) were included. A deductive qualitative content analysis was conducted to extract meaningful functioning and disability concepts from verbatim material. Extracted concepts were then linked to ICF(-CY) categories by independent researchers using a standardized linking procedure. In total, 82 ICF(-CY) categories were identified, of which 32 were related to activities and participation, 25 to environmental factors, 23 to body functions and 2 to body structures. Participants also provided opinions on experienced positive sides to ADHD. A high level of energy and drive, creativity, hyper-focus, agreeableness, empathy, and willingness to assist others were the most consistently reported strengths associated with ADHD. Stakeholder perspectives highlighted the need to appraise ADHD in a broader context, extending beyond diagnostic criteria into many areas of ability and disability as well as environmental facilitators and barriers. This qualitative study, along with three other studies (comprehensive scoping review, expert survey and clinical study), will provide the scientific basis to define ICF(-CY) Core Sets for ADHD, from which assessment tools can be derived for use in clinical and research setting, as well as in health care administration.

Effectiveness of an online SUpport PRogramme (SUPR) for older hearing aid users: study protocol for a cluster randomised controlled trial

BACKGROUND

An educational SUpport PRogramme called SUPR has been developed for hearing aid users (HAUs) and their communication partners (CPs) offering care beyond hearing aid fitting. SUPR teaches its users communication strategies, hearing aid handling skills and personal adjustment to hearing impairment.

METHODS/DESIGN

Using a cluster randomised controlled trial design, 70 Dutch hearing aid dispenser practices were randomised into hearing aid fitting (care as usual, 34 practices) and hearing aid fitting including SUPR (36 practices). The aim was to recruit a total of 569 older (aged 50+ years) first-time (n=258) and experienced (n=311) HAUs and their CPs. SUPR consists of a Practical Support Booklet and online material offered via email over a period of 6-7 months. The booklet provides practical information on hearing aids, advice on communication strategies and home exercises. The online material consists of educational videos on hearing aid functionality and usage, communication strategies and peer testimonials. Finally, noncommittal email contact with the dispenser is offered. Every HAU is asked to assign a CP who is advised to be involved intensively. Effect measurements for HAUs and their CPs will occur at baseline and at 6, 12 and 18 months follow-up via online questionnaires. The primary outcomes for HAUs will be the use of communication strategies as measured by the subscales of the Communication Profile for the Hearing Impaired. A process evaluation will be performed.

ETHICS AND DISSEMINATION

The study was approved by the Dutch Institutional Review Board of the VU Medical University Center Amsterdam. This intervention could contribute to lowering the hearing impairment burden in our ageing society. The results will be disseminated through peer-reviewed publications and scientific conferences.

Exploring the Relevance of Items in the Communicative Participation Item Bank (CPIB) for Individuals With Hearing Loss

PURPOSE

The Communicative Participation Item Bank (CPIB) was developed to evaluate participation restrictions in communication situations for individuals with speech and language disorders. This study evaluated the potential relevance of CPIB items for individuals with hearing loss.

METHOD

Cognitive interviews were conducted with 17 adults with a range of treated and untreated hearing loss, who responded to 46 items. Interviews were continued until saturation was reached and prevalent trends emerged. A focus group was also conducted with 3 experienced audiologists to seek their views on the CPIB. Analysis of data included qualitative and quantitative approaches.

RESULTS

The majority of the items were applicable to individuals with hearing loss; however, 12 items were identified as potentially not relevant. This was largely attributed to the items' focus on speech production rather than hearing. The results from the focus group were in agreement for a majority of items.

CONCLUSIONS

The next step in validating the CPIB for individuals with hearing loss is a psychometric analysis on a large sample. Possible outcomes could be that the CPIB is considered valid in its entirety or the creation of a new questionnaire or a hearing loss-specific short form with a subset of items is necessary.

Dimensions of tinnitus-related complaints reported by patients and their significant others: protocol for a systematic review

INTRODUCTION

Over 70 million people in Europe and >50 million people in the USA are reported to experience tinnitus (the sensation of noise in the absence of any corresponding sound source). Tinnitus is a multidimensional concept. Individual patients may report different profiles of tinnitus-related symptoms which may each require a tailored management approach and an appropriate measure of therapeutic benefit. This systematic review concerns the patient perspective and has the purpose to find what symptoms are reported by people who experience tinnitus and by their significant others.

METHODS AND ANALYSIS

This protocol lays out the methodology to define what dimensions of tinnitus-related symptoms patients and their significant others report as being a problem. Methods are defined according to the Preferred Reporting Items for Systematic reviews and Meta-analyses for Protocols (PRISMA-P) 2015 and data will be collated in a narrative synthesis. Findings will contribute to the eventual establishment of a Core Domain Set for clinical trials of tinnitus.

ETHICS AND DISSEMINATION

No ethical issues are foreseen. Findings will be reported at national and international ENT and audiology conferences and in a peer-reviewed journal.

Domains relating to the everyday impact of hearing loss, as reported by patients or their communication partner(s): protocol for a systematic review

INTRODUCTION

Hearing loss is a highly prevalent condition that affects around 1 in 6 people in the UK alone. This number is predicted to rise by the year 2031 to a staggering 14.5 million people due to the ageing population of the UK. Currently, the most common intervention for hearing loss is amplification with hearing aid(s) which serve to address the issue of audibility due to hearing loss, but cannot reverse its effects. The consequences of hearing loss are multifaceted, as it is a complex condition that can detrimentally affect various aspects of an individual's life, including communication and personal relationships. The scope of these reported issues is so broad that it calls on the need for patient-centred management plans that are tailored to each patient as well as appropriate measures to assess intervention benefit. It is unclear whether current outcome instruments adequately match what patients report as the most important problems for them.

METHODS AND ANALYSIS

The systematic review aims to capture existing knowledge about patients and their communication partner's perspective on the everyday impact of hearing loss. Methods are defined according to the Preferred Reporting Items for Systematic reviews and Meta-analyses for Protocols (PRISMA-P) 2015.

ETHICS AND DISSEMINATION

No ethical issues are foreseen. Findings will be reported in student's thesis as well as at national and international ENT/audiology conferences and in a peer-reviewed journal.

Interventions to improve hearing aid use in adult auditory rehabilitation

BACKGROUND

Acquired adult-onset hearing loss is a common long-term condition for which the most common intervention is hearing aid fitting. However, up to 40% of people fitted with a hearing aid either fail to use it or may not gain optimal benefit from it. This is an update of a review first published in The Cochrane Library in 2014.

OBJECTIVES

To assess the long-term effectiveness of interventions to promote the use of hearing aids in adults with acquired hearing loss fitted with at least one hearing aid.

SEARCH METHODS

The Cochrane ENT Information Specialist searched the Cochrane ENT Trials Register; Central Register of Controlled Trials (CENTRAL 2016, Issue 5); PubMed; EMBASE; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 13 June 2016.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of interventions designed to improve or promote hearing aid use in adults with acquired hearing loss compared with usual care or another intervention. We excluded interventions that compared hearing aid technology. We classified interventions according to the 'chronic care model' (CCM). The primary outcomes were hearing aid use (measured as adherence or daily hours of use) and adverse effects (inappropriate advice or clinical practice, or patient complaints). Secondary patient-reported outcomes included quality of life, hearing handicap, hearing aid benefit and communication. Outcomes were measured over the short (</= 12 weeks), medium (> 12 to < 52 weeks) and long term (one year plus).

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane.

MAIN RESULTS

We included 37 studies involving a total of 4129 participants. Risk of bias across the included studies was variable. We judged the GRADE quality of evidence to be very low or low for the primary outcomes where data were available.The majority of participants were over 65 years of age with mild to moderate adult-onset hearing loss. There was a mix of new and experienced hearing aid users. Six of the studies (287 participants) assessed long-term outcomes.All 37 studies tested interventions that could be classified using the CCM as self-management support (ways to help someone to manage their hearing loss and hearing aid(s) better by giving information, practice and experience at listening/communicating or by asking people to practise tasks at home) and/or delivery system design interventions (just changing how the service was delivered). Self-management support interventions We found no studies that investigated the effect of these interventions on adherence, adverse effects or hearing aid benefit. Two studies reported daily hours of hearing aid use but we were unable to combine these in a meta-analysis. There was no evidence of a statistically significant effect on quality of life over the medium term. Self-management support reduced short- to medium-term hearing handicap (two studies, 87 participants; mean difference (MD) -12.80, 95% confidence interval (CI) -23.11 to -2.48 (0 to 100 scale)) and increased the use of verbal communication strategies in the short to medium term (one study, 52 participants; MD 0.72, 95% CI 0.21 to 1.23 (0 to 5 scale)). The clinical significance of these statistical findings is uncertain. It is likely that the outcomes were clinically significant for some, but not all, participants. Our confidence in the quality of this evidence was very low. No self-management support studies reported long-term outcomes. Delivery system design interventionsThese interventions did not significantly affect adherence or daily hours of hearing aid use in the short to medium term, or adverse effects in the long term. We found no studies that investigated the effect of these interventions on quality of life. There was no evidence of a statistically or clinically significant effect on hearing handicap, hearing aid benefit or the use of verbal communication strategies in the short to medium term. Our confidence in the quality of this evidence was low or very low. Long-term outcome measurement was rare. Combined self-management support/delivery system design interventionsOne combined intervention showed evidence of a statistically significant effect on adherence in the short term (one study, 167 participants, risk ratio (RR) 1.06, 95% CI 1.00 to 1.12). However, there was no evidence of a statistically or clinically significant effect on daily hours of hearing aid use over the long term, or the short to medium term. No studies of this type investigated adverse effects. There was no evidence of an effect on quality of life over the long term, or short to medium term. These combined interventions reduced hearing handicap in the short to medium term (15 studies, 728 participants; standardised mean difference (SMD) -0.26, 95% CI -0.48 to -0.04). This represents a small-moderate effect size but there is no evidence of a statistically significant effect over the long term. There was evidence of a statistically, but not clinically, significant effect on long-term hearing aid benefit (two studies, 69 participants, MD 0.30, 95% CI 0.02 to 0.58 (1 to 5 scale)), but no evidence of an effect over the short to medium term. There was evidence of a statistically, but not clinically, significant effect on the use of verbal communication strategies in the short term (four studies, 223 participants, MD 0.45, 95% CI 0.15 to 0.74 (0 to 5 scale)), but not the long term. Our confidence in the quality of this evidence was low or very low.We found no studies that assessed the effect of other CCM interventions (decision support, the clinical information system, community resources or health system changes).

AUTHORS' CONCLUSIONS

There is some low to very low quality evidence to support the use of self-management support and complex interventions combining self-management support and delivery system design in adult auditory rehabilitation. However, effect sizes are small. The range of interventions that have been tested is relatively limited. Future research should prioritise: long-term outcome assessment; development of a core outcome set for adult auditory rehabilitation; and study designs and outcome measures that are powered to detect incremental effects of rehabilitative healthcare system changes.

Aphasia and Auditory Processing after Stroke through an International Classification of Functioning, Disability and Health Lens

Aphasia is an acquired language impairment affecting speaking, listening, reading, and writing. Aphasia occurs in about a third of patients who have ischemic stroke and significantly affects functional recovery and return to work. Stroke is more common in older individuals but also occurs in young adults and children. Because people experiencing a stroke are typically aged between 65 and 84 years, hearing loss is common and can potentially interfere with rehabilitation. There is some evidence for increased risk and greater severity of sensorineural hearing loss in the stroke population and hence it has been recommended that all people surviving a stroke should have a hearing test. Auditory processing difficulties have also been reported poststroke. The International Classification of Functioning, Disability and Health (ICF) can be used as a basis for describing the effect of aphasia, hearing loss, and auditory processing difficulties on activities and participation. Effects include reduced participation in activities outside the home such as work and recreation and difficulty engaging in social interaction and communicating needs. A case example of a young man (M) in his 30s who experienced a left-hemisphere ischemic stroke is presented. M has normal hearing sensitivity but has aphasia and auditory processing difficulties based on behavioral and cortical evoked potential measures. His principal goal is to return to work. Although auditory processing difficulties (and hearing loss) are acknowledged in the literature, clinical protocols typically do not specify routine assessment. The literature and the case example presented here suggest a need for further research in this area and a possible change in practice toward more routine assessment of auditory function post-stroke.

The International Classification of Functioning, Disability and Health as a Framework for Providing Patient- and Family-Centered Audiological Care for Older Adults and Their Significant Others

Hearing impairment is highly prevalent in the older population, and it impacts communication and quality of life for both the people with the hearing difficulties and their significant others. In this article, typical audiological assessment and management of an older adult is contrasted with a best practice approach wherein the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework is applied. The aim of the comparison is to demonstrate how the ICF expands our focus: rather than merely focusing on impairment, we also consider the activities, participation, and contextual factors for both the person with the hearing impairment and his or her family. A case example of an older patient and her spouse is provided, and their shared experience of the patient's hearing impairment is mapped onto the ICF framework. Family-centered hearing care is recommended for individualizing care and improving outcomes for older patients and their families.

Hearing and Cognitive Impairment and the Role of the International Classification of Functioning, Disability and Health as a Rehabilitation Framework

The International Classification of Functioning, Disability and Health (ICF) has been applied widely in the literature to describe and differentiate the broad implications of hearing impairment (HI) and cognitive impairment (CI) on communication. As CI and HI are largely age-related conditions, the likelihood of comorbidity of these conditions is high. In the context of an aging population, the prevalence of comorbidity is likely to rise, yet much of the clinical assessment and intervention in HI and CI occur separately. The benefit of addressing the dual impact of these conditions is of increasing clinical importance for all clinicians working with older adults and for audiologists and speech pathologists in particular. In this article, the ICF model will be applied to explore the everyday implications of HI and CI. Furthermore, the clinical implications of the ICF model are explored with particular respect to communication assessment and intervention options. The potential benefit of combining activity- and participation-focused interventions currently offered for HI and CI independently is examined.

What Is the International Classification of Functioning, Disability and Health and Why Is It Relevant to Audiology?

The World Health Organization's International Classification of Functioning, Disability and Health (ICF) is widely used in disability and health sectors as a framework to describe the far-reaching effects of a range of health conditions on individuals. This biopsychosocial framework can be used to describe the experience of an individual in the components of body functions, body structures, and activities and participation, and it considers the influence of contextual factors (environmental and personal) on these components. Application of the ICF in audiology allows the use of a common language between health care professionals in both clinical and research settings. Furthermore, the ICF is promoted as a means of facilitating patient-centered care. In this article, the relevance and application of the ICF to audiology is described, along with clinical examples of its application in the assessment and management of children and adults with hearing loss. Importantly, the skills necessary for clinicians to apply the ICF effectively are discussed.

Reevaluation of the Amsterdam Inventory for Auditory Disability and Handicap Using Item Response Theory

PURPOSE

We reevaluated the psychometric properties of the Amsterdam Inventory for Auditory Disability and Handicap (AIADH; Kramer, Kapteyn, Festen, & Tobi, 1995) using item response theory. Item response theory describes item functioning along an ability continuum.

METHOD

Cross-sectional data from 2,352 adults with and without hearing impairment, ages 18-70 years, were analyzed. They completed the AIADH in the web-based prospective cohort study "Netherlands Longitudinal Study on Hearing." A graded response model was fitted to the AIADH data. Category response curves, item information curves, and the standard error as a function of self-reported hearing ability were plotted.

RESULTS

The graded response model showed a good fit. Item information curves were most reliable for adults who reported having hearing disability and less reliable for adults with normal hearing. The standard error plot showed that self-reported hearing ability is most reliably measured for adults reporting mild up to moderate hearing disability.

CONCLUSIONS

This is one of the few item response theory studies on audiological self-reports. All AIADH items could be hierarchically placed on the self-reported hearing ability continuum, meaning they measure the same construct. This provides a promising basis for developing a clinically useful computerized adaptive test, where item selection adapts to the hearing ability of individuals, resulting in efficient assessment of hearing disability.
