Work areas
The project has eight work areas to start up consecutively. The first three areas are active from project start and includes studies of existing practice and pilot tests of new methods. The next two areas start slightly later and will test and evaluate new strategies. The following two areas will revise the most promising new methods for clinical practice and assess the potential for user-controlled rehabilitation. Finally, one work area is to transfer relevant results to new guidelines and standards.
Centralized clinical database
Before we may develop and propose new methods and guidelines, we want to be sure that we have a well-defined and unequivocal reference, which represents typical rehabilitation experiences. We will map the rehabilitation procedure for patients that receive rehabilitation in the participating clinics in the first years of the project. We will study the relations between the hearing diagnostics applied, the hearing aids received, their fitting, and what the outcome is for each patient. A considerable part of the work is to build the database, which will also serve as a platform for patient data for the other work areas. Data for almost 2000 patients have been registered and is currently being analyzed

As a starting point, a large clinical database has been prepared to better characterize the current clinical status in Denmark. The analysis will be used to identify the main challenges faced by hearing aid users in order to develop appropriate tools to improve performances. Method: The study is a multicentre, prospective, open, non-randomized, single-arm trial with sequential enrolment of all qualified patients, conducted under a common clinical investigation plan. Up to almost 2,000 evaluable patients have been enrolled from two Danish clinics. After having undergone medical and audiological examination and other assessments (health related and quality of life questionnaires), the patients were prescribed a hearing aid and got a fitting. Approximately 2 months later, a follow-up visit took place and whenever needed an adjustment was offered (plus other assessments). An across-center database, hosted independently from clinics, universities and hearing-aid manufacturers but accessible by all parties, was created to gather the data (access granted to each partner if data managers adhere to ethical permissions and requirements for data security). Results: The investigation generated approximately 30’000 patient records and we started by characterizing the general distribution of audiometric data (air and bone conductions, speech tests) and questionnaires (health, speech, hearing aids, tinnitus and quality of life related).

As a starting point, a large clinical database has been prepared to better characterize the current clinical status in Denmark. The analysis will be used to identify the main challenges faced by hearing aid users in order to develop appropriate tools to improve performances. Method: The study is a multicentre, prospective, open, non-randomized, single-arm trial with sequential enrolment of all qualified patients, conducted under a common clinical investigation plan. Up to almost 2,000 evaluable patients have been enrolled from two Danish clinics. After having undergone medical and audiological examination and other assessments (health related and quality of life questionnaires), the patients were prescribed a hearing aid and got a fitting. Approximately 2 months later, a follow-up visit took place and whenever needed an adjustment was offered (plus other assessments). An across-center database, hosted independently from clinics, universities and hearing-aid manufacturers but accessible by all parties, was created to gather the data (access granted to each partner if data managers adhere to ethical permissions and requirements for data security). Results: The investigation generated approximately 30’000 patient records and we started by characterizing the general distribution of audiometric data (air and bone conductions, speech tests) and questionnaires (health, speech, hearing aids, tinnitus and quality of life related). The analysis focused specifically on correlations detection between demographics, audiometric tests and questionnaires in order to classify patients into subsets. Conclusion: The present clinical database should be seen as a starting point for other BEAR work packages. We believe that such large variety of data generated will lead to a more comprehensive picture of the hearing-aid user and will bring benefits to both clinicians and manufacturers. Indeed, this first step represents the baseline against which new fitting strategies will be tested. Alternatively, clinically relevant subpopulations with low hearing-aid benefit will be identified and studied to tentatively bring alternatives in rehabilitation. |

Moreover, this questionnaire includes a question related to hearing (D3). When completed before and after hearing aid (HA) treatment, this questionnaire assesses the potential benefits of HA treatment on HRQoL. Method: Prospective clinical trial with HA treatment as intervention. The data were collected by means of self-reported questionnaires (15D and a basic health-related questionnaire) before and two months following HA-fitting. The study population (n=1536) comprised of both first time HA users (n=1096) and experienced HA users (n=440) enrolled in the multicenter better hearing rehabilitation (BEAR) project. Results: HA treatment resulted in improved mean score of D3 for both new (∆D3: mean, SD (0.102; 0.19) and experienced (∆D3: mean, SD (0.083; 0.20) HA users following 2 months of HA use. Patients with both “moderate to severe” and “severe” hearing loss, defined by the GBD hearing impairment classification, experienced a significant improvement in D3. Discussion: The study supports that HA usage has a positive effect on HRQoL and that HA treatment results in improved HRQoL when looking at the hearing dimension. Degree of hearing loss alone does not explain the positive effect observed. Therefore, additional parameters need to be studied in order to explain which factors are essential for patients with HL to be able to achieve an improvement of HRQoL following HA-fitting.}, keywords = {}, pubstate = {published}, tppubtype = {conference} } Introduction: The 15-Dimension instrument (15D) is a standardized, self-administered, generic questionnaire that provides a profile (D1-15 score) and a single index score (D15-score) as a measure of health-related quality of life (HRQoL) on a scale with a range between zero and one.

Despite efforts to provide hearing aids (HA) to people in need, hearing loss remains an unmet need.

To improve the treatment, we propose to revise diagnostic techniques and HA fitting practices based on individual hearing profiles, set of expectations, and lifestyles. To achieve this, a cooperative project “BEAR” has been launched between three national universities, three hospitals, and the HA industry in Denmark. This resulted in the building of a database of over 30,000 patient records, collected by two audiologic departments (Aalborg and Odense, Denmark), from January 2017 until April 2018 from 1,963 hearing impaired patients. Data obtained describe procedures which are currently used in clinical audiology across Denmark and allow to explore which measures are available for each patient and what type of HA fitting they have received. Records consisted of audiometric data (air and bone conduction, uncomfortable levels, speech reception thresholds speech discrimination scores, stapedius reflex and tympanometry, Tinnitus Handicap Inventory), quality of life evaluation using questionnaires (health related quality of life [15-D], Health Related Questionnaires, Charlson Comorbidity Index), HA outcome measures using questionnaires (Speech, Spatial and Qualities of Hearing scale [SSQ-12], International Outcome Inventory for Hearing Aids [IOI-HA]) and HA fitting data (HA types, log data, fitting rationale and real-ear measurements). The database has a gender ratio of 126 males for 100 females, a mean age at 67 years (range from 19 to 100 years) and a mean hearing threshold in the better hearing ear of 40 dB HL (four frequencies average). 71.9 percent of the patients are first time HA users, as against 28.1 percent for patients with previous HA experience. Preliminary analyses show on average significant improvement in hearing abilities with HA (from IOI-HA and SSQ-12). However, substantial number of participants (18%) did not derive enough benefit from HA. Further analysis will be directed towards finding the possible reasons and grouping the participants based on HA benefit, demographic and audiological data.
