abstract = {The purpose of the present study was to identify the terms hearing aid professionals and their patients use in the communication about the aided listening experience and develop scales that would help characterize this experience in the domain of corrective actions that a hearing care professional may apply. The study comprised a word elicitation study based on observations and interviews from 18 examinations, involving 7 audiologists, 2 medical audiologists, and 15 adult patients from the audiological department at Aalborg University Hospital. The words patients and professionals used for describing the aided listening experience were itemized, noted on cards, and analyzed by developing an affinity diagram. The resulting 80 words were then sorted by three hearing professionals in a supervised card sorting session, leaving 65 attributes (grouped in 13 main categories) that was considered suitable for suggesting corrective actions. These 65 attributes were included in a 63-point scale design, which (in a usability test including 8 hearing aid users) were considered easy to survey and use, but also including some redundancy and ambiguities. The results suggest that it is possible to develop scales based on the voluntary statements expressed during actual consultations, but that the expressions may not be interpreted the same way by other patients and professionals.},

abstract = {The aim of the present pilot study was to assess daily life experiences of new hearing aid users and explore ways to utilize these assessments in a follow-up situation with the hearing care provider. The method was designed as an online pass-time activity, where the patients swipe through the randomly presented experiences, and select the ones they have had recently. The sentences were expected to evoke the memory of recent experiences and provide a language for the patients to describe these. Thirty new hearing aid users were included in the study. Data were collected over a period of two months and consisted of 453 pre-fabricated sentences representing experiences related to HA use. Each sentence correlated with one of 13 categories covering both auditory and non-auditory aspects. Data for each patient was visualized to elucidate both short- and long-term challenges and successes experienced, as well as irrelevant and not experienced situations. Presently the first three patients included in the study have completed a two-month follow-up. The overall response rate is 63% taking into account that some patients may not have started the log activity yet as the work is ongoing.},

abstract = {Patients often experience hearing difficulties despite the use of HA (hearing aids). The difficulties may be related to a number of auditory and non-auditory factors such as benefit, comfort, maintenance etc. It is difficult for both the patient and the audiologist to know, if the fitting and the given outcome is the best possible. The sound may be experienced differently in the clinic compared to daily life and the knowledge and skills related to hearing aid use vary largely from patient to patient. The aim of the present study is to gain insight into the daily experiences of new hearing aid users, which may shed light on aspects of aided performance, which may not be unveiled through standard questionnaires or during consultation.
Data is collected online and consists of more than 400 pre-fabricated sentences representing experiences related to HA use. The sentences have been developed based on observations, involvement of experts, and inspired by elements from validated questionnaires. Patients are asked to relate to each experience (sentence) on a regular basis over a period of two months. The method is designed as a pass-time activity, where the patients swipe through the randomly presented experiences, and select the ones they have had recently.
The sentences are expected to evoke the memory of recent experiences in the patients and at the same time provide a language to describe these. The two-month data-logging is expected to elucidate the short- and long-term challenges of each patient and thus provide a useful feedback – and maybe adjustment – tool in a follow-up situation.

The work is on-going. Data will be analyzed and if feasible, summarized in a feedback tool for the professionals for a two-month follow-up.

The study is part of BEAR project funded by Innovation Fund Denmark and partners (incl. Oticon, GN Resound and Widex). Funding and collaboration is sincerely appreciated.},

abstract = {Background: Denmark has currently no formal requirements for testing and documenting the aided listening performance and outcome obtained with hearing aids rehabilitation. Yet most professionals both validate and assess the aided listening experience in various ways as part of the fitting procedure and in follow-up assessments. The goal of the present study was to observe standard clinical practice and identify methods and actions currently used, and examine their potential for formalization and inclusion in guidelines, or replacement by existing formalized procedures.

Material and methods: The relevant professionals receive a major part of their training through supervised internships, and it is anticipated that much of their knowledge is tacit and informal. The general methods for the study therefore comprise a combination of interviews with and observations of professionals during hearing-aid fitting and at two-month follow-up. Observations and contextual inquiries of the clinical practice were made in three public hearing clinics in Denmark including 17 professionals, which were either medical audiologists (ENT doctors), audiology assistants or professionals in audiologopedics. These are the main categories of professionals involved in hearing-aid fitting in public clinics in Denmark. Each professional participated between two and ten hours in the present study.

Results: The results show that professionals assess outcome using methods, which are often individually and tacitly anchored covering 1) validation of basic hearing aid functionality, 2) patient awareness on gain with hearing aids, 3) access to knowledge on patient experiences through sound descriptions, 4) assessment of aided performance in real life and 5) non-auditory assessments.

Conclusion: Some of the informal methods observed may be formalized as a part of a more patient-centered communication strategy – other need further examination or may be replaced by existing, already validated formal frameworks, or by test batteries under development.
