Development and Formative Assessment of the Hearing Loss Toolkit for Self-Management

Effect of Hearing Intervention Versus Health Education Control on Fatigue: A Secondary Analysis of the ACHIEVE Study

BACKGROUND

Fatigue is a common complaint among older adults with hearing loss. The impact of addressing hearing loss on fatigue symptoms has not been studied in a randomized controlled trial. In a secondary analysis of the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) study, we investigated the effect of hearing intervention versus health education control on 3-year change in fatigue in community-dwelling older adults with hearing loss.

METHODS

Participants aged 70-84 years old with untreated hearing loss recruited across 4 study sites in the United States (Forsyth County, North Carolina; Jackson, Mississippi; Minneapolis, Minnesota; Washington County, Maryland) were randomized (1:1) to hearing intervention or health education control and followed for 3 years. Three-year change in fatigue symptoms was measured by 2 instruments (RAND-36 and PROMIS). We estimated the intervention effect as the difference in the 3-year change in fatigue between intervention and control groups using a linear mixed-effects model under the intention-to-treat principle.

RESULTS

Participants (n = 977) had a mean age (SD) of 76.8 (4.0) years, were 53.5% female and 87.8% White. Over 3 years, a beneficial effect of the hearing intervention versus health education control on fatigue was observed using the RAND-fatigue score (β = -0.12 [95% CI: -0.22, -0.02]). Estimates also suggested beneficial effect of hearing intervention on fatigue when measured by the PROMIS-fatigue score (β = -0.32 [95% CI: -1.15, 0.51]).

CONCLUSIONS

Our findings suggest that hearing intervention may reduce fatigue over 3 years among older adults with hearing loss.

Development and Validation of Self-Management Manual for Acute Tinnitus

The aim of the study was to develop a self-management manual for tinnitus. The study was carried out in three phases. In phase-1, an evidence-based approach was considered by reviewing the literature to select intervention strategies that had proven to reduce tinnitus percept. Further, health literacy recommendations were used to convey the information in the manual to the patient. Phase-2 included expert committee scrutiny and assessing the understandability and actionability of the prepared self-management manual using the Patient Education Material Assessment Tool (PEMAT). In Phase-3, the self-management manual was validated from tinnitus patients. The expert committee mainly gave suggestions regarding the content, word choice and grammatical errors. PEMAT scores from patients and the expert committee revealed that activities provided in the manual are understandable and actionable. The THI and TFI scores were reduced after one month of short-term intervention. The self-management manual effectively reduced tinnitus percept and associated problems.

A Perspective on Auditory Wellness: What It Is, Why It Is Important, and How It Can Be Managed

During the last decade, there has been a move towards consumer-centric hearing healthcare. This is a direct result of technological advancements (e.g., merger of consumer grade hearing aids with consumer grade earphones creating a wide range of hearing devices) as well as policy changes (e.g., the U.S. Food and Drug Administration creating a new over-the-counter [OTC] hearing aid category). In addition to various direct-to-consumer (DTC) hearing devices available on the market, there are also several validated tools for the self-assessment of auditory function and the detection of ear disease, as well as tools for education about hearing loss, hearing devices, and communication strategies. Further, all can be made easily available to a wide range of people. This perspective provides a framework and identifies tools to improve and maintain optimal auditory wellness across the adult life course. A broadly available and accessible set of tools that can be made available on a digital platform to aid adults in the assessment and as needed, the improvement, of auditory wellness is discussed.

Feasibility and Assessment of a Hybrid Audiology Service Delivery Model for Older Adult Hearing Aid Users: A Pilot Study

PURPOSE

The aim of this study was to provide insight for the feasibility and outcomes of hybrid (combination of in-person office and Internet-based appointments) audiology services.

METHOD

This pilot included two phases. First, we surveyed audiologists regarding what elements of a best-practice, in-person delivery of a hearing intervention could be delivered via Internet-based appointments. Next, we piloted the feasibility and assessed outcomes of the procedures identified. Ten first-time hearing aid users aged 70 years and older were fit with Phonak Audeo M90-312T hearing aids. Two Internet-based follow-up appointments were completed using the myPhonak app. We administered the Hearing Handicap Inventory for the Elderly-Screening Version (HHIE-S), the Client Oriented Scale of Improvement (COSI), the Quick Speech-in-Noise Test (QuickSIN), and real-ear aided responses (REARs) to determine whether participants experienced improvements on hearing-related outcomes. The Telehealth Acceptance Questionnaire (TAQ) and the Visit-Specific Satisfaction Questionnaire (VSQ-9) were administered to gauge comfort with telehealth and satisfaction with Internet-based appointments.

RESULTS

Survey results revealed that after an initial in-person appointment, nearly all follow-up hearing intervention components could be delivered remotely. We performed Wilcoxon signed-ranks tests to determine if the baseline and outcome results differed for outcomes. Baseline scores improved after 6 weeks (ps = .02 and. 005 for QuickSIN and HHIE-S) for speech-in-noise performance and self-perceived hearing difficulties. REARs from 500 to 4000 Hz measured after 6 weeks did not differ from baseline (ps = .612 and .398 for the right and left ears), suggesting no significant deviation from prescriptive targets because of remote fitting adjustments. All participants reported improvement in COSI goals after the intervention. TAQ results suggested that comfort with telehealth improved after attending Internet-based appointments (p = .005). VSQ-9 results revealed no differences in reported patient satisfaction between in-person and Internet-based appointments.

CONCLUSIONS

We were able to develop a feasible hybrid audiology service delivery model for older adults. Our results enhance the evidence base for the implementation of telehealth audiology services.

Development, assessment, and monitoring of audiologic treatment fidelity in the aging and cognitive health evaluation in elders (ACHIEVE) randomised controlled trial

OBJECTIVE

Studies investigating hearing interventions under-utilise and under-report treatment fidelity planning, implementation, and assessment. This represents a critical gap in the field that has the potential to impede advancements in the successful dissemination and implementation of interventions. Thus, our objective was to describe treatment fidelity planning and implementation for hearing intervention in the multi-site Ageing and Cognitive Health Evaluation in Elders (ACHIEVE) randomised controlled trial.

DESIGN

Our treatment fidelity plan was based on a framework defined by the National Institutes of Health Behaviour Change Consortium (NIH BCC), and included strategies to enhance study design, provider training, and treatment delivery, receipt, and enactment.

STUDY SAMPLE

To assess the fidelity of the ACHIEVE hearing intervention, we distributed a checklist containing criteria from each NIH BCC core treatment fidelity category to nine raters.

RESULTS

The ACHIEVE hearing intervention fidelity plan satisfied 96% of NIH BCC criteria. Our assessment suggested a need for including clear, objective definitions of provider characteristics and non-treatment aspects of intervention delivery in future fidelity plans.

CONCLUSIONS

The ACHIEVE hearing intervention fidelity plan can serve as a framework for the application of NIH BCC fidelity strategies for future studies and enhance the ability of researchers to reliably implement evidence-based interventions.

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

OBJECTIVES

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

DESIGN

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

RESULTS

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

CONCLUSIONS

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

The Hearing Intervention for the Aging and Cognitive Health Evaluation in Elders Randomized Control Trial: Manualization and Feasibility Study

OBJECTIVES

This work describes the development of a manualized best-practice hearing intervention for older adults participating in the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) randomized controlled clinical trial. Manualization of interventions for clinical trials is critical for assuring intervention fidelity and quality, especially in large multisite studies. The multisite ACHIEVE randomized controlled trial is designed to assess the efficacy of a hearing intervention on rates of cognitive decline in older adults. We describe the development of the manualized hearing intervention through an iterative process that included addressing implementation questions through the completion of a feasibility study (ACHIEVE-Feasibility).

DESIGN

Following published recommendations for manualized intervention development, an iterative process was used to define the ACHIEVE-hearing intervention elements and create an initial manual. The intervention was then delivered within the ACHIEVE-Feasibility study using one-group pre-post design appropriate for assessing questions related to implementation. Participants were recruited from the Tampa, Florida area between May 2015 and April 2016. Inclusion criteria were cognitively healthy adults aged 70 to 89 with symmetrical mild-to-moderately severe sensorineural hearing loss. The ACHIEVE-Feasibility study sought to assess the implementation of the manualized hearing intervention by: (1) confirming improvement in expected outcomes were achieved including aided speech-in-noise performance and perception of disease-specific self-report measures; (2) determining whether the participants would comply with the intervention including session attendance and use of hearing aids; and (3) determining whether the intervention sessions could be delivered within a reasonable timeframe.

RESULTS

The initial manualized intervention that incorporated the identified best-practice elements was evaluated for feasibility among 21 eligible participants and 9 communication partners. Post-intervention expected outcomes were obtained with speech-in-noise performance results demonstrating a significant improvement under the aided condition and self-reported measures showing a significant reduction in self-perceived hearing handicap. Compliance was excellent, with 20 of the 21 participants (95.2%) completing all intervention sessions and 19 (90.4%) returning for the 6-month post-intervention visit. Furthermore, self-reported hearing aid compliance was >8 hr/day, and the average daily hearing aid use from datalogging was 7.8 hr. Study completion was delivered in a reasonable timeframe with visits ranging from 27 to 85 min per visit. Through an iterative process, the intervention elements were refined, and the accompanying manual was revised based on the ACHIEVE-Feasibility study activities, results, and clinician and participant informal feedback.

CONCLUSION

The processes for the development of a manualized intervention described here provide guidance for future researchers who aim to examine the efficacy of approaches for the treatment of hearing loss in a clinical trial. The manualized ACHIEVE-Hearing Intervention provides a patient-centered, yet standardized, step-by-step process for comprehensive audiological assessment, goal setting, and treatment through the use of hearing aids, other hearing assistive technologies, counseling, and education aimed at supporting self-management of hearing loss. The ACHIEVE-Hearing Intervention is feasible in terms of implementation with respect to verified expected outcomes, compliance, and reasonable timeframe delivery. Our processes assure intervention fidelity and quality for use in the ACHIEVE randomized controlled trial (ClinicalTrials.gov Identifier: NCT03243422).

Cross-Cultural Adaptation of Hearing Loss Self-Management Patient Education Materials: Development of the Caja de Instrumentos de Pérdida Auditiva

Purpose The lack of culturally and linguistically appropriate interventions contributes to unsatisfactory hearing health care service delivery and outcomes for Spanish-speaking persons from Hispanic/Latino background. To address this issue, our objective was to cross-culturally adapt a "Hearing Loss Toolkit for Self-Management" for use with Spanish-speaking adults seen in a clinical setting. In this clinical focus article, we describe a process for translation and cross-cultural adaptation of patient education materials based on current best practices guidelines. Method We utilized guidelines from the International Society for Pharmoeconomics Outcomes Research Task Force for Translation and Cultural Adaptation, the World Health Organization, and the International Collegium of Rehabilitative Audiology to complete a comprehensive, systematic, cross-cultural adaptation process of the source materials. The adaptation stages included forward translation and reconciliation, back translation and review, field testing with representative end users from the target population, and finalization. Results We successfully cross-culturally adapted the source materials following best practice guidelines. The Spanish-language adaptation was deemed understandable, actionable, aesthetically pleasing, and culturally appropriate by a group of native Spanish speakers. Conclusions There is an unmet need for the development of hearing loss self-management materials that incorporate cultural and linguistic competence with best health literacy practices. High-quality cross-cultural adaptations that consider the intersection of culture, language, and health literacy are a positive step toward reducing barriers to hearing health care related to language access for U.S. Hispanic/Latino adults with hearing loss.
