abstract = {Speech understanding in noisy environments has been the most desired hearing aid (HA) benefit sought by hearing aid users. This paper examines the possibility of developing a speech related HA benefit index from correlated speech related questions from three different self-reported questionnaire's (SSQ12, IOI-HA, and 15D). The 4 questions in SSQ12 (question number 1,4,11 and 12), 3 questions in IOI-HA(question number 3,5 and 6) and 3rd question from health-related quality of life questionnaire 15D relating to speech were found correlated and are chosen for further analysis. After the normalization of the relevant questions, a principal component analysis (PCA) is used to reduce the dimensionality and determine the coefficients. The resultant coefficients are used to create a common speech related HA benefit index.},

abstract = {Background: Hearing aid (HA) satisfaction is assessed by the self-administered International Outcome Inventory of Hearing Aids (IOI-HA) questionnaire. Objectives: The aims of the current study were to investigate the level of HA satisfaction for experienced and first time HA users, and to evaluate any difference between self-reported and objectively measured HA usage time (through data logging). Design: Self-reported questionnaire survey. Patients enrolled in the national BEAR project, from January 2017 to January 2018, answered the seven-item IOI-HA questionnaire targeting different hearing outcome domains; each scored from 1-5. Data logged HA usage time was obtained at two months follow-up visits and compared to the self-reported usage time obtained from the initial IOI-HA questionnaire item. Results: The study population (n=1649) comprised of both experienced (n=458) and first time HA users (n=1191). Total mean IOI-HA scores for experienced HA users increased by ∆0,36 (SD=0,92). Differences in levels of satisfaction between the two groups were further analyzed. Moreover, data logged usage time for experienced users was 10.4 hours (SD=5,10) and 8.35 hours (SD=1,02) for first time users. 15,9% of experienced users (n=422) reported in average a usage time from 4 to 8 hours whereas 21,5% of first time users (n=1152) reported in average 4 to 8 hours usage time.},

When completed before and after hearing aid (HA) treatment the questionnaire can be used to assess the potential benefits of HA treatment related to HRQoL. Overall health status was collected by questionnaires (15D and a basic health-related questionnaire) before and two months after HA fitting. The study population (n=1536) comprised first time HA users (n=1096) and experienced HA users (n=440) enrolled in the BEAR project. HA resulted in improved mean score of D3 for both first time (∆D3: mean, SD (0.102; 0.19)) and experienced (∆D3: mean, SD (0.083; 0.20)) HA users after 2 months of HA use. Patients with "moderate to severe" and "severe" hearing loss, experienced a significant improvement in D3-HRQoL. The study supports that HA usage has a positive effect on HRQoL when looking at the hearing dimension. Degree of hearing loss alone does not explain the positive effect observed on D3-HRQoL. Therefore, additional parameters need to be studied in order to explain essential factors for patients with HL to be able to achieve an improvement of HRQoL following HA fitting.},

abstract = {Background: The purpose of the BEAR project is to improve hearing loss management by revising diagnostic techniques and hearing aid fitting practices based on individual hearing profiles, expectations and lifestyle. 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.},

abstract = {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. 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.},

abstract = {A recent report from WHO noted that 360 million people in the world have hearing loss. Despite efforts to provide hearing aids (HA) to people in need, hearing loss remains an unmet need. In Denmark, for example, 20% of HA owners do not use their HA regularly which results in wasted clinical resources and a lack of rehabilitation. 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. This will enable us to identify the areas, among contemporary standard examinations and hearing fitting strategies, which would be relevant to explore, change or further develop to provide a better HA fitting and thereby a greater user satisfaction.},
