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.
