Validierung und Reliabilitätsprüfung des Nijmegen Cochlear Implant Questionnaire in deutscher Sprache

Zusammenfassung Hintergrund Der Nijmegen Cochlear Implant Questionnaire (NCIQ) ist ein krankheitsspezifischer Fragebogen zur Erhebung der gesundheitsbezogenen Lebensqualität von Patienten vor und nach Cochleaimplantation. Ziel der Arbeit Validierung und Reliabilitätsprüfung der deutschen Übersetzung des NCIQ. Material und Methoden Es wurde eine prospektive Studie an 100 postlingual ertaubten oder hochgradig schwerhörigen Patienten durchgeführt, welche präoperativ sowie 3 und 6 Monate nach einer Cochleaimplantation mittels NCIQ, Abbreviated Profile of Hearing Aid Benefit (APHAB) und Hearing Participation Scale (HPS) untersucht wurden. Als Kontrolle fungierte ein postlingual ertaubtes oder hochgradig schwerhöriges, unbehandeltes Patientenkollektiv (n = 54). Cronbach‑α und Test-Retest-Reliabilität dienten der Reliabilitätsüberprüfung. Es wurde auf Inhalts‑, Übereinstimmungs- und auf diskriminative Validität getestet. Die Konstruktvaliditätsprüfung basiert auf kürzlich veröffentlichen Daten. Als Gütekriterien wurden die Sensitivität und eine ROC(„Receiver Operating Characteristic“)-Analyse, inklusive AUC(„Area Under the ROC Curve“)-Betrachtung, eingesetzt. Ergebnisse Das Test-Retesting ergab nach 3 und 6 Monaten postoperativ stabile NCIQ-Werte. Die Cronbach-α-Werte wiesen auf eine gute interne Konsistenz hin. Der NCIQ diskriminierte valide zwischen behandelten und unbehandelten Patientengruppen. Es ergaben sich statistisch signifikante, wenn auch schwache, Korrelationen zwischen dem NCIQ und dem APHAB (r = −0,22; p = 0,04) und dem HPS (r = 0,30; p = 0,01). Sensitivitäts- und ROC-Analysen zeigten eine gute Messqualität des deutschsprachigen NCIQ. Schlussfolgerung Die deutsche Übersetzung des NCIQ misst zuverlässig und valide die Lebensqualität vor und nach Cochleaimplantation und kann zur klinischen Erfolgskontrolle nach Cochleaimplantationen verwendet werden.

Hearing Aid Consumer Reviews: A Linguistic Analysis in Relation to Benefit and Satisfaction Ratings

Purpose Online reviews have been used by hearing aid owners to share their experiences and to provide suggestions to potential hearing aid buyers, although they have not been systematically examined. The study was aimed at examining the hearing aid consumer reviews using automated linguistic analysis, and how the linguistic variables relate to self-reported hearing aid benefit and satisfaction ratings. Method The study used a cross-sectional design. One thousand three hundred seventy-eight consumer hearing aid reviews (i.e., text response to open-ended question), self-reported benefit and satisfaction ratings on hearing aids in a 5-point scale with meta-data (e.g., hearing aid brand, technology level) extracted from the Hearing Tracker website were analyzed using automated text analysis method known as the Linguistic Inquiry and Word Count. Results Self-reported hearing aid benefit and satisfaction ratings were high (i.e., mean rating of 4.04 in a 5-point scale). Examining the association between overall rating and the key linguistic variables point to two broad findings. First, the more people were personally, socially, and emotionally engaged with the hearing device experience, the higher they rated their hearing device(s). Second, a minimal occurrence of clinic-visit language dimensions points to factors that likely affect benefit and satisfaction ratings. For example, if people mention paying too much money (money), their overall ratings are generally lower. Conversely, if people write about their health or home, the ratings were higher. There was no significant difference in linguistic analysis across different hearing aid brands and technology levels. Conclusions Hearing aid consumers are generally satisfied with their hearing device(s), and their online reviews contain information about social/emotional dimensions as well as clinic-visit related aspects that have bearing toward hearing aid benefit and satisfaction ratings. These results suggest that the natural language used by consumers provide insights on their perceived benefit/satisfaction from their hearing device.

Results of the Active Middle Ear Implantation in Patients With Mixed Hearing Loss After the Middle Ear Surgery: Prospective Multicenter Study (ROMEO Study)

Objectives. To evaluate the user satisfaction, efficacy, and safety of round window (RW) vibroplasty using the Vibrant Soundbridge (VSB) in patients with persistent mixed hearing loss after mastoidectomy.Methods. The study included twenty-seven patients (mean age, 58.7 years; age range, 28–76 years; 11 men and 16 women) with mixed hearing loss after mastoidectomy surgery from 15 tertiary referral centers in Korea. The VSB was implanted at the RW. The Korean translation of the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire and the Korean version of the International Outcome Inventory for Hearing Aids (K-IOI-HA) questionnaire were used to evaluate user satisfaction as the primary outcome. Secondary outcome measures were audiological test results and complication rates.Results. The mean scores on the Ease of Communication (61.3%

Surgical and functional outcomes of two types of transcutaneous bone conduction implants

Objective This study aimed to evaluate surgical and functional outcomes, in a tertiary referral centre, of two different types of semi-implantable transcutaneous bone conduction devices. Method This study involved prospective data collection and review of patients implanted between November 2014 and December 2016. Glasgow Hearing Aid Inventory (Glasgow Hearing Aid Benefit Profile or Glasgow Hearing Aid Difference Profile) and Client Oriented Scale of Improvement were completed where appropriate. Surgical and audiological outcomes were recorded in the surgical notes. Results Glasgow Hearing Aid Difference Profile and Glasgow Hearing Aid Benefit Profile showed similar mean score in the active and the passive transcutaneous bone conduction devices. Client Oriented Scale of Improvement showed improvements in listening situations. Post-operative speech reception threshold showed better mean threshold in the active transcutaneous bone conduction devices group when compared with the passive transcutaneous bone conduction devices group. No device failures or surgical complications existed in either group, with the surgical time being less in the passive transcutaneous bone conduction devices group. Conclusion Both devices are reliable semi-implantable transcutaneous bone conduction devices with excellent surgical and functional outcomes and patient satisfaction. Overall surgical time was much less in the passive transcutaneous bone conduction devices group with no necessity for pre-planning. This is much easier to remove with the possibility of conversion to other devices in the manufacturer’s portfolio and wide-ranging wireless accessories. Further studies are needed to assess the longer-term results in a bigger population.

Clinical Application and Psychometric Properties of a Swedish Translation of the Abbreviated Profile of Hearing Aid Benefit

Background: The impact of hearing loss on the individual and his/her everyday life can be assessed using questionnaires with the purpose to improve rehabilitation quality. The Abbreviated Profile of Hearing Aid Benefit (APHAB) can be used to evaluate disability in everyday life associated with hearing loss. Previous studies have examined APHAB outcomes in sensorineural hearing loss and we do not know whether the type of hearing loss influence questionnaire outcomes. Purpose: The purpose was to evaluate the psychometric properties of a Swedish translation of the APHAB and the influence of demographic variables on the outcome in a clinical sample. Research Design: A descriptive, cross-sectional study in a clinical sample. Study Sample: Forty-eight participants with no hearing aid experience seeking audiological rehabilitation for the first time. These participants represented different degrees of hearing loss and three types of hearing loss: monaural mixed, binaural mixed, and binaural sensorineural hearing loss. Data Collection and Analysis: Pure-tone audiometry was conducted and the participants completed the unaided APHAB during their first appointment at the clinic. Psychometric properties of the questionnaire were examined and the influence of age, gender, type of hearing loss, and degree of hearing loss on APHAB scores were studied. Results: The psychometric properties indicate high test-retest reliability but there seems to be some potential issues with the properties of the reverberation (RV) subscale. The items from the RV subscale failed to load as a separate component and the internal consistency of the subscale improved by removing four items (items 1, 9, 11, and 16). With few exceptions, APHAB scores were not influenced by age, gender, or type of hearing loss. APHAB scores were generally influenced by degree of hearing loss in both the best and the worst ear. Conclusion: This Swedish version of the APHAB can be additionally improved by addressing the inconsistencies found in the RV subscale by rephrasing or removing some items. The degree of hearing loss has some influence on questionnaire outcomes but not age, gender, and type of hearing loss.

Development of Korean Version of Profile of Hearing Aid Benefit-Quick Version

Purpose: The purpose of this study was to develop the Korean version of profile of hearing aid benefit-quick version (K-PHAB-Q) which shortens 20 questions of K-PHAB into 10 for efficient evaluation of hearing aids benefit. Methods: First, responses for the questionnaires were collected from 140 hearing aid users (average age: 67.39). K-PHAB-Q consists of ease of communication (EC), background noise (BN), reverberation (RV), aversiveness of sounds (AV) and localization (LC), and was verified through factor analysis, principal component analysis, and Cronbach’s alpha analysis for a total of 10 selected items. Second, the K-PHAB-Q questionnaire was collected by test-retesting for a total of 40 hearing aid users (average age: 71.98). The collected questionnaires were verified by paired <i>t</i>-test and Pearson correlation coefficient, and the 95% prediction interval (PI) was calculated to establish the standard of change in subjective satisfaction on hearing aid users. Results: The results of this study were 1) according to Cronbach’s alpha analysis of K-PHAB-Q, the internal consistency of all items was high as 0.854, 2) test-retest result of K-PHAB-Q showed no significant difference (r > 0.05) and showed high correlation in all items, 3) The 95% PI of EC, BN, RV, AV, and LC showed ± 16.823, ± 17.734, ± 12.123, ± 14.404, and ± 8.193 respectively. Conclusion: K-PHAB-Q, will be useful for hearing aid verification or validation at hearing aid fitting management sites in a short time.

Next-Day Loading of a Bone-Anchored Hearing System: Preliminary Results

Objectives To demonstrate the feasibility and efficacy for next-day loading of a percutaneous bone-anchored hearing device. Study Design Multicenter prospective cohort study. Setting Tertiary neurotologic referral centers. Subject and Methods In this multicenter prospective study, a 4.5-mm laser-etched bone-anchored hearing device was implanted in adult subjects who had conductive/mixed hearing loss or single-sided deafness. One day following implantation, the surgical site was assessed for soft tissue reaction per the Holgers Scale, and implant stability was evaluated by manual palpation and resonance frequency analysis. On the same day, subjects were fitted with the processor. Follow-up evaluations were at 1 week, 4 weeks, 3 months, 6 months, and 12 months. The Glasgow Benefit Inventory and Abbreviated Profile of Hearing Aid Benefit questionnaires were completed postoperatively. Results Fourteen devices were implanted in 12 subjects. Two subjects underwent bilateral implantation. Implant stability was rated as firm at every interval for all ears, and the Implant Stability Quotient values at 3 months were stable or increased as compared with day 1 measurements. Skin irritation was limited to Holgers grade 0 and 1, with the majority having no skin irritation. The mean Glasgow Benefit Inventory global score was +43.8, and the mean Abbreviated Profile of Hearing Aid Benefit global benefit score was 60.2%. All 14 implants have remained firmly anchored. Conclusions Next-day loading of this 4.5-mm-diameter percutaneous bone-anchored hearing device appears to be a feasible alternative to the original 3-month delayed loading. Although this is a preliminary study, the results support continued investigation of a next-day loading strategy.

The use of speech sentence audiometry in a free sound field

Objectives -to determine the normative data of sentence speech intelligibility in a free sound field and to estimate the applicability of the Russian Matrix Sentence test (RuMatrix) for assessment of the hearing aid fitting benefit. Material and methods. 10 people with normal hearing and 28 users of hearing aids with moderate to severe sensorineural hearing loss were involved in the study. RuMatrix test both in quiet and in noise was performed in a free sound field. All patients filled in the COSI questionnaire. Results. The hearing impaired patients were divided into two subgroups: the 1st with high and the 2nd with low hearing aid benefit, according to the COSI questionnaire. In the 1st subgroup, the threshold for the sentence intelligibility in quiet was 34.9 ± 6.4 dB SPL, and in noise -3.3 ± 1.4 dB SNR, in the 2nd subgroup 41.7 ± 11.5 dB SPL and 0.15 ± 3.45 dB SNR, respectively. The significant difference between the data of both subgroups and the norm was registered (p
