The ICF core sets for hearing loss project: International expert survey on functioning and disability of adults with hearing loss using the international classification of functioning, disability, and health (ICF)

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.

Development of ICF core set to profile communicative competence in dyadic communication among adults who use communication devices in Taiwan

PURPOSE

This study aimed to develop an ICF core set to profile communicative competence in dyadic communication among adults who use communication devices in Taiwan.

MATERIALS AND METHODS

The study was conducted following the release of a manual by the World Health Organisation (WHO) on how to develop the International Classification of Functioning, Disability and Health (ICF) core set in three phases: Preparatory Phase, Phase I, and Phase II. The Preparatory Phase helped collect and sort second-level ICF codes into a candidate list based on different perspectives, including the Systematic Literature Review Phase (i.e., researchers' perspectives), Empirical Multi-Center Study Phase (i.e., clinical perspectives), Qualitative Study Phase (i.e., perspectives of individuals with a health condition), and Expert Survey Phase (i.e., health professionals' perspectives). An ICF core set was developed from the candidate list in Phase I through the Delphi technique, and the content validity of this core set was assessed in Phase II.

RESULTS

Altogether, 94 s-level ICF codes in the candidate list from the Preparatory Phase were included in the three rounds of the Delphi technique for Phase I. Finally, these 94 s-level ICF codes were validated and included in the core set for Phase II, including 28 in Body Functions (b), 0 in Body Structures (s), 42 in Activities and Participation (d), and 24 in Environmental Factors (e).

CONCLUSIONS

The developed ICF core set provides an evaluation tool to profile communicative competence in dyadic communication among adults using communication devices. This core set identifies the gap and future opportunities for further examining the care providers' roles, together with exploring the environmental facilitators and barriers. The implications concerning rehabilitation, limitations, and the way forward are discussed.Implications to RehabilitationThis core set was first developed in the context of Taiwan from the perspectives of adults and professionals who used communication devices to profile communicative competence in dyadic communication.This core set, which can be utilised across health care disciplines, can serve as the foundation for more holistic evaluation, profiling levels of communicative competence in daily dyadic communication among adults who use communication devices.Rehabilitation providers may decide, based on this core set, if communication devices should be proposed for adults again in order to minimise the abandonment of subsidised communication devices.Levels of communicative competence in daily dyadic communication among adults who use communication devices can be profiled through this ICF core set.

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.

Patient-Reported Outcome Measures for Hearing Aid Benefit and Satisfaction: Content Validity and Readability

PURPOSE

Numerous patient-reported outcome measures (PROMs) are available to measure hearing aid benefit and satisfaction. It is unclear to what extent currently available PROMs on hearing aid outcomes, often developed decades ago, meet current guidelines for good content validity and readability. This study evaluated the content validity and readability of PROMs that focus on perceived hearing aid benefit and/or satisfaction.

METHOD

A literature review was conducted to identify eligible instruments. Content validity evaluation included mapping extracted questionnaire items to the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework. In addition, study design in content validity methodology was evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments study design checklist for PROM instruments. Readability was estimated using the Simple Measure of Gobbledygook measure.

RESULTS

Thirteen questionnaires were identified and evaluated. Item content focused primarily on the components of environmental factors as well as activity limitations and participation restrictions with less emphasis on body functions and personal factors. The content validity methodology analysis revealed an underuse or lack of reporting of a qualitative methodology in assessing patient and professional perspectives. All the included questionnaires exceeded the recommended sixth-grade reading level.

CONCLUSIONS

The categories covered by hearing aid PROMs vary considerably, with no single instrument comprehensively covering all the key ICF components. Future development of hearing aid outcome measures should consider a mixed methodology approach for improved content validity and ensure an appropriate reading level.

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.

Did Changes to Adult Hearing Aid Pathways Due to COVID-19 Affect Patient Outcomes? A Service Evaluation

Objective:

The objective of this study was to determine whether changes to adult hearing aid provision during COVID-19 affected patient outcomes or service efficiency.

Design:

A service evaluation compared three cohorts: patients who had hearing aid provision prior to the COVID-19 pandemic (the conventional pathway); patients who had hearing aid provision during the initial national lockdown (remote fittings); and patients who had hearing aid provision during the gradual reopening phase (a blended service with both face-to-face and remote service provision). Outcomes measured the effectiveness and efficiency of the service, using the Glasgow Hearing Aid Benefit/Difference Profiles (GHABP/DP) and number of follow-up appointments required. Results were assessed using descriptive statistics and error bars, separately for new and existing users.

Sample:

This study included 240 hearing aid users.

Results:

Remote fittings adversely impacted the effectiveness of provision for new hearing aid users with a reduction in all GHABP domains. While new users' benefit was equally as good for blended and conventional service provision, blended provision was less efficient and required more follow-up visits. For existing hearing aid users, no differences were seen in GHADP outcomes of different pathways and remote fittings increased service efficiency.

Conclusions:

Remote hearing aid fittings are less effective for new users than hearing aids fitted using standard face-to-face service provision or service provision using a blended model of remote and face-to-face care. Current pathways using a blended model of care are less efficient but equally effective for new hearing aid users compared with provision prior to COVID-19 and result in equivalent patient outcomes in terms of benefit.

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.

Effect of electrical stimulation with a cochlear implant on tinnitus impact: protocol of an individual patient data meta-analysis

INTRODUCTION

Tinnitus is the perception of sound without an external stimulus, often experienced as a ringing, buzzing sound. While several studies have shown a reduction in tinnitus distress following cochlear implantation, others showed an increase or no change after implantation. At this stage, clinicians have little certainty when counselling their patients prior to implantation regarding tinnitus post-implantation. To help clinicians to counsel cochlear implant (CI) candidates on the risk of developing or improving tinnitus after implantation, we aim to assess the effect of electrical stimulation with a CI on tinnitus impact for individual adult patients with tinnitus. We will also apply prediction models to individual patient data (IPD) of clinical trials to find predictive factors of the effect of electrical stimulation on tinnitus impact.

METHOD AND ANALYSIS

The IPD meta-analysis is a follow-up project of the systematic review on cochlear implantation in patients with tinnitus as a primary complaint. First, the systematic searches will be updated to date. Methodological quality of eligible studies will be assessed using the Risk of Bias In Non-randomised Studies of Intervention tool (ROBINS-I). Based on a data-sharing agreement, authors of the eligible studies will be invited to share their deidentified and complete IPD. The primary outcome is the effect of electrical stimulation with a CI on tinnitus impact 1 month or more post-implantation. IPD meta-analysis will be used to assess the primary outcome, while differentiating the tinnitus impact questionnaires. Second, linear regression analyses will be used to model the effect of electrical stimulation on tinnitus impact based on relevant predictors.

ETHICS AND DISSEMINATION

The Medical Research Involving Human Subject Act does not apply, and ethical approval is not required. The study results will be made accessible to the public in a peer-review open access journal.

The development of the International Classification of Functioning, Disability and Health Core Sets for deafblindness: A study protocol

BACKGROUND

Individuals with deafblindness experience a combination of hearing and vision impairments. The World Health Organization has developed a global framework referred to as the International Classification of Functioning, Disability and Health (ICF) to describe health and functioning. From the full ICF classification, a selection of categories, referred to as ICF Core Sets, provide users with a tool to describe functioning and disability in specific health conditions. There has been no ICF Core Set created for deafblindness. Given that core sets are instrumental in improving clinical practice, research, and service delivery, the aim of this study is to develop an ICF Core Set for deafblindness.

METHODS

As part of the preparatory phase in the ICF Core Set development, there are four studies that will be conducted. This includes the [1] systematic literature review that examines the researcher's perspective, [2] qualitative study focusing on the individuals with deafblindness experience, [3] experts survey that looks at health professional's perspective, and [4] empirical study that examines the clinical perspective. The studies will be conducted using the principles outlined by the ICF Research Branch for the development of ICF Core Sets. The systematic literature review protocol was submitted for registration on PROSPERO CRD42021247952.

DISCUSSION

An ICF Core Set created for deafblindness will benefit individuals living with deafblindness who are often excluded from social participation, policies, and services. An ICF Core Set for deafblindness will have a significant impact on healthcare professionals, policymakers, researchers, service providers and individuals with deafblindness by facilitating communication among all stakeholder to support the functioning of those with deafblindness.

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.

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.

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.

Social representation of hearing aids among people with hearing loss: an exploratory study

OBJECTIVE

The aim of the current study was to examine the social representation (SR) of hearing aids in people with hearing loss (PHL) in India, the Republic of Korea (ROK), the United Kingdom (UK), and the United States of America (US).

DESIGN

The study used a cross-sectional survey design. The data collected by using a free association task were analysed qualitatively (i.e. content analysis) and quantitatively (i.e. chi-square analysis, similarities analysis, prototypical analysis).

STUDY SAMPLE

424 participants with hearing loss.

RESULTS

The most commonly reported categories across all countries were "beneficial," "cost and time," and "appearance and design." Approximately 50% of the associations reported were negative. There were variations in terms of the categories that were predominant in the SR of each country. "Others actions and attitude" category was predominantly reported by PHL in India. "Disturbance" and "dissatisfaction" of hearing aids and the "repairs and maintenance of hearing aids" categories were mainly reported from the ROK and the US, respectively.

CONCLUSIONS

The current results highlight the main aspects that PHL report spontaneously when they think about hearing aids. The findings will help to further inform public health campaigns and will contribute to develop culturally appropriate media materials regarding hearing aids.

Conceptual Model of Hearing Health Inequalities (HHI Model): A Critical Interpretive Synthesis

Hearing loss is a major health challenge that can have severe physical, social, cognitive, economic, and emotional consequences on people's quality of life. Currently, the modifiable factors linked to socioeconomic inequalities in hearing health are poorly understood. Therefore, an online database search (PubMed, Scopus, and Psych) was conducted to identify literature that relates hearing loss to health inequalities as a determinant or health outcome. A total of 53 studies were selected to thematically summarize the existing literature, using a critical interpretive synthesis method, where the subjectivity of the researcher is intimately involved in providing new insights with explanatory power. The evidence provided by the literature can be summarized under four key themes: (a) There might be a vicious cycle between hearing loss and socioeconomic inequalities and lifestyle factors, (b) socioeconomic position may interact with less healthy lifestyles, which are harmful to hearing ability, (c) increasing health literacy could improve the diagnosis and prognosis of hearing loss and prevent the adverse consequences of hearing loss on people's health, and (d) people with hearing loss might be vulnerable to receiving low-quality and less safe health care. This study uses elements from theoretical models of health inequalities to formulate a highly interpretive conceptual model for examining hearing health inequalities. This model depicts the specific mechanisms of hearing health and their evolution over time. There are many modifiable determinants of hearing loss, in several stages across an individual's life span; tackling socioeconomic inequalities throughout the life-course could improve the population's health, maximizing the opportunity for healthy aging.

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.

Clinical validation of the Russian Matrix test - effect of hearing loss, age, and noise level

OBJECTIVE

To validate the Russian matrix sentence test (RUMatrix) for the assessment of speech recognition in quiet and in noise in clinical praxis. The effect of hearing impairment, age, and masking-noise level on speech recognition was examined.

DESIGN

All participants underwent pure tone audiometry, a monosyllabic speech test in quiet, and speech recognition measurements with RUMatrix in quiet (SRT_Q) and in noise (SRT_N).

STUDY SAMPLE

One hundred and forty-two listeners divided into four groups: 1. Young normal-hearing listeners, 2. Older normal-hearing listeners, 3. Young hearing-impaired listeners, and 4. Older hearing-impaired listeners.

RESULTS

Significant differences between groups of listeners were found in the SRT_Q and SRT_N. A strong correlation between hearing threshold and SRT_Q (R²=0.88, p < 0.001) indicates a strong link between speech recognition in quiet and audibility. The pure-tone average explained less variance in SRT_N (R²=0.67, p < 0.001), pointing out an additional influence of suprathreshold distortion. A high test sensitivity of 0.99 was found for SRT_N and SRT_Q. The monosyllabic test had a low sensitivity (0.21), indicating that the test is not suitable for separating normal-hearing and hearing-impaired listeners.

CONCLUSIONS

RuMatrix is a reliable speech recognition assessment tool with a high sensitivity and validity for the main aspects of hearing impairment.

Development and Application of an Annotation Procedure to Assess the Impact of Hearing Aid Amplification on Interpersonal Communication Behavior

Hearing impairment is associated with a decrease in speech intelligibility and health-related quality of life, such as social isolation and participation restriction. However, little is known about the extent to which hearing impairment and hearing aid fittings change behavior in acute communication situations as well as interrelated behavior patterns. Based on a pilot study, in which the basis for annotating communication behavior was laid, group discussions in noise were initiated with 10 participants using three different hearing-aid brands. The proposed offline annotation scheme revealed that different hearing aids were associated with changes in behavior patterns. These behavioral changes were congruent with speech recognition threshold results and also with subjective assessments. Some of the results were interpreted in terms of participation restriction and activity limitation following the framework of the International Classification of Functioning, Disability and Health. In addition to the offline annotation scheme, a procedure for instantaneous coding of eight behavior patterns was iteratively developed and used for the quick examination of lab studies with good to excellent interrater reliability values.

Self-Stigma and Age-Related Hearing Loss: A Qualitative Study of Stigma Formation and Dimensions

PURPOSE

This study explored experiences of self-stigma among older persons with age-related hearing loss (ARHL) using Corrigan's conceptualization of self-stigma process formation and the attribution model as its theoretical framework.

METHOD

In-depth semistructured interviews were conducted with 11 older persons (mean age = 81 years) with ARHL.

RESULTS

Self-stigma was present in the lives of the participants. Analysis revealed the existence of 3 stages of self-stigma in which the 3 core dimensions of stigma (cognitive attributions: being old, stupid, and crippled; emotional reactions: shame, pity, and feeling ridiculed; and behavioral reactions: concealment, distancing, and adapting to hearing aids) were observed. Hearing devices emerged as having a significant influence on stigmatic experiences in all stages and dimensions of self-stigma.

CONCLUSION

The study contributes to the theoretical and practical understanding of self-stigma regarding ARHL as well as to the understanding of the role of hearing devices in the development of this stigma.

Examination of Previously Published Data to Identify Patterns in the Social Representation of 'Hearing Aids' Across Countries

Background and Objectives

Societal factors seem to exercise a strong influence on hearing aid uptake, use, and satisfaction. In particular, knowledge, perception, and attitude of people will have bearing towards their and others health behavior and decisions. The current study aimed at understanding the perception of hearing aids by adults belonging to the general population in different countries.

Subjects and Methods

The study employed a crosssectional design. A sample of 404 adults from India, Iran, Portugal, and the United Kingdom were recruited by relying on a convenience sampling. Previously published data was re-analyzed but it was applied for different approach. Free association task was used to collect the data. They were asked to provide up to five words or phrases that come to mind when thinking about “hearing aids.” The data was initially analyzed based on qualitative content analysis. This was followed by quantitative cluster analysis and chi square analysis.

Results

The content analysis suggested 39 main categories of responses related to hearing aids. The cluster analysis resulted in five main clusters, namely: 1) positive attitude, 2) external factors, 3) hearing aid use and satisfaction, 4) etiology, and 5) benefits and limitations of technology. A few demographic factors (i.e., education, occupation type, country) showed association with different clusters, although country of origin seemed to be associated with most clusters.

Conclusions

The study provides us with unique insights into the perception of hearing aids by the general public, and additionally, the way demographic variables may influence these perceptions.

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.

Surgeon Reported Outcome Measure for Spine Trauma: An International Expert Survey Identifying Parameters Relevant for the Outcome of Subaxial Cervical Spine Injuries

STUDY DESIGN

International web-based survey.

OBJECTIVE

To identify clinical and radiological parameters that spine surgeons consider most relevant when evaluating clinical and functional outcomes of subaxial cervical spine trauma patients.

SUMMARY OF BACKGROUND DATA

Although an outcome instrument that reflects the patients' perspective is imperative, there is also a need for a surgeon reported outcome measure to reflect the clinicians' perspective adequately.

METHODS

A cross-sectional online survey was conducted among a selected number of spine surgeons from all five AOSpine International world regions. They were asked to indicate the relevance of a compilation of 21 parameters, both for the short term (3 mo-2 yr) and long term (≥2 yr), on a five-point scale. The responses were analyzed using descriptive statistics, frequency analysis, and Kruskal-Wallis test.

RESULTS

Of the 279 AOSpine International and International Spinal Cord Society members who received the survey, 108 (38.7%) participated in the study. Ten parameters were identified as relevant both for short term and long term by at least 70% of the participants. Neurological status, implant failure within 3 months, and patient satisfaction were most relevant. Bony fusion was the only parameter for the long term, whereas five parameters were identified for the short term. The remaining six parameters were not deemed relevant. Minor differences were observed when analyzing the responses according to each world region, or spine surgeons' degree of experience.

CONCLUSION

The perspective of an international sample of highly experienced spine surgeons was explored on the most relevant parameters to evaluate and predict outcomes of subaxial cervical spine trauma patients. These results form the basis for the development of a disease-specific surgeon reported outcome measure, which will be a helpful tool in research and clinical practice.

Identification of problems in the functioning of individuals with schizophrenia from the expert perspective: an Internet-based survey

PURPOSE

The purpose of the study was to identify aspects of functioning and related environmental factors that are relevant to schizophrenia from the perspective of health professionals experienced in treating individuals with this disorder using the International Classification of Functioning, Disability and Health (ICF).

METHOD

An international pool of experts from diverse health care disciplines was surveyed to identify problems in functioning experienced by individuals with schizophrenia and the environmental factors that impact their functioning. On the basis of established rules, all answers were translated to the ICF by two independent researchers.

RESULTS

One-hundred and eighty-nine experts from all six World Health Organization regions identified 4776 meaningful concepts, of which 92% were linked to 347 different ICF categories. Of the 347 categories, 194 were second-level categories, 151 were third-level categories and 2 were fourth-level categories. Ninety-five second-level ICF categories, 43 third-level categories and 1 fourth-level category reached percentage frequency of at least 5%. The majority of the categories were attributed to body functions, activities and participation, and environmental factors.

CONCLUSIONS

Health professionals identified a wide range of problems in functioning that reflect the complexity and breadth of schizophrenia, specifically activity limitations and participation restrictions that are particularly relevant for individuals with schizophrenia. Knowing these functioning problems can guide the design of patient-oriented rehabilitation programmes. Implications for rehabilitation Schizophrenia may result in impaired functioning in multiple daily life activities. The International Classification of Functioning, Disability and Health (ICF) can help in identifying the needs and problems of these individuals. The reported list of ICF categories can facilitate a systematic application of the ICF in schizophrenia and can help to design and implement coordinated and patient oriented rehabilitation programmes with a biopsychosocial approach. According to health professionals surveyed, activity limitations and participation restrictions are broadly affected in this population and are highly influenced by neurocognitive and social cognitive deficits and environmental factors.

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.

Functioning and disability in autism spectrum disorder: A worldwide survey of experts

OBJECTIVE

This study is the second of four to prepare International Classification of Functioning, Disability and Health (ICF; and Children and Youth version, ICF(-CY)) Core Sets for Autism Spectrum Disorder (ASD).The objective of this study was to survey the opinions and experiences of international experts on functioning and disability in ASD.

METHODS

Using a protocol stipulated by the World Health Organization (WHO) and monitored by the ICF Research Branch, an email-based questionnaire was circulated worldwide among ASD experts, and meaningful functional ability and disability concepts were extracted from their responses. These concepts were then linked to the ICF(-CY) by two independent researchers using a standardized linking procedure.

RESULTS

N = 225 experts from 10 different disciplines and all six WHO-regions completed the survey. Meaningful concepts from the responses were linked to 210 ICF(-CY) categories. Of these, 103 categories were considered most relevant to ASD (i.e., identified by at least 5% of the experts), of which 37 were related to Activities and Participation, 35 to Body functions, 22 to Environmental factors, and 9 to Body structures. A variety of personal characteristics and ASD-related functioning skills were provided by experts, including honesty, loyalty, attention to detail and creative talents. Reported gender differences in ASD comprised more externalizing behaviors among males and more internalizing behaviors in females.

CONCLUSION

The ICF(-CY) categories derived from international expert opinions indicate that the impact of ASD on functioning extends far beyond core symptom domains.

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.

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.

Social representation of "hearing loss": cross-cultural exploratory study in India, Iran, Portugal, and the UK

Background

Hearing loss is one of the most common chronic conditions in older adults. In audiology literature, several studies have examined the attitudes and behavior of people with hearing loss; however, not much is known about the manner in which society in general views and perceives hearing loss. This exploratory study was aimed at understanding the social representation of hearing loss (among the general public) in the countries of India, Iran, Portugal, and the UK. We also compared these social representations.

Materials and methods

The study involved a cross-sectional design, and participants were recruited using the snowball sampling method. A total of 404 people from four countries participated in the study. Data were collected using a free-association task where participants were asked to produce up to five words or phrases that came to mind while thinking about hearing loss. In addition, they were also asked to indicate if each word they presented had positive, neutral, or negative associations in their view. Data were analyzed using various qualitative and quantitative methods.

Results

The most frequently occurring categories were: assessment and management; causes of hearing loss; communication difficulties; disability; hearing ability or disability; hearing instruments; negative mental state; the attitudes of others; and sound and acoustics of the environment. Some categories were reported with similar frequency in most countries (eg, causes of hearing loss, communication difficulties, and negative mental state), whereas others differed among countries. Participants in India reported significantly more positive and fewer negative associations when compared to participants from Iran, Portugal, and the UK. However, there was no statistical difference among neutral responses reported among these countries. Also, more differences were noted among these countries than similarities.

Conclusion

These findings provide useful insights into the public perception of hearing loss that may prove useful in public education and counseling.

Social representation of hearing aids: cross-cultural study in India, Iran, Portugal, and the United Kingdom

BACKGROUND

The current study was aimed at understanding the social representation of hearing aids in India, Iran, Portugal, and the United Kingdom. We also compared these results to explore the cross-cultural differences and similarities among these countries.

METHODS

The study involved a cross-sectional design, and the data were collected from four different countries using the snowball sampling method. Data were analyzed using a content analysis to identify the most-similar categories of responses reported, a co-occurrences analysis to see which of these categories are reported commonly, and a chi-square analysis to study if there was any association between positive, neutral, and negative connotations among participants in different countries.

RESULTS

The current study revealed four different social representations of hearing aids from India, Iran, Portugal, and the United Kingdom, and also a global index.

CONCLUSION

The study results provide very useful insights into how hearing aids are represented in the society. These findings may have important implications for public education and also for manufacturers from the viewpoint of designing and marketing hearing aids in different countries.
