An investigation of factors that influence help-seeking for hearing impairment in older adults

Abstract

Objective: To examine the influence of audiological and non-audiological factors on help-seeking for hearing impairment (HI) in older adults. Design: A retrospective research design was employed. Participants completed 14 measures, after which two multivariate, multinomial logistic regression models were fitted to the data to determine which factors were associated with consultation for HI and hearing aid uptake. Study sample: Three-hundred-and-seven individuals who were 60 years or older and who presented with a unilateral or bilateral HI participated in the study. Non-hearing aid owners were assigned to a non-consulter group (n = 55) or a consulter group (n = 92); hearing aid owners were assigned to an unsuccessful hearing aid owner group (n = 75) or a successful hearing aid owner group (n = 85). Results: A similar combination of factors was associated with the decisions to consult a health professional about HI and/or to adopt hearing aids. The most important factors related to attitudinal beliefs (e.g. perceived benefits of hearing aids) and external cues to action (e.g. support from significant others). Greater HI also influenced consultation and adoption of hearing aids. Conclusions: Findings highlight the importance of non-audiological factors in hearing rehabilitation to improve consultation for HI and hearing aid adoption.     

Audiological management of adults with hearing impairment in Malaysia

Objective: This study explored the nature of audiological services for adults with hearing impairment in Malaysia, with an emphasis on whether current services address clients’ overall functioning as described by the World Health Organisation’s International Classification of Functioning, Disability, and Health (ICF) framework. Design: An online survey exploring current practice, skills and confidence of audiologists, and the infrastructure and facilities available in their workplaces, was distributed to audiologists in Malaysia via professional associations and social media. Study sample: A total of 111 audiologists, 84.7% female and 15.3% male (range?=?23–44 years), participated in the study. Results: Although audiologists in Malaysia reported addressing all of the ICF domains, less than 26% of them assessed the patients’ speech perception, carried out real-ear measurements, or used outcome measures routinely. The majority of the audiologists reported feeling confident in managing adult patients. However, 83% of the audiologists indicated they wanted to improve their skills related to management of adult patients, particularly in the areas of counselling and auditory training. Conclusions: Inadequate infrastructure, resources and facilities in the workplace may have contributed to the gaps in service provision and influenced the current practice of audiological management for adult patients in Malaysia.     

Exploring the relationship between technology use,hearing help-seeking,and hearing aid outcomes in older adults

Abstract

Objective: The objective of this study was to explore technology use and its relationship to help-seeking for hearing impairment (HI) and success with hearing aids among older adults. Previous research had suggested a link between higher levels of technology use and hearing aid success. Design: General technology use was evaluated using a purposefully developed 25-item questionnaire. Twelve items related to everyday technology use (e.g. DVD player) and 13 related to advanced technology use (e.g. Bluetooth). Study sample: Four groups of older adults with HI participated in the study: (1) non-consulters (n = 49), (2) consulters (n = 62), (3) unsuccessful hearing aid owners (n = 61), and (4) successful hearing aid owners (n = 79). Results: Preliminary analyses revealed a main effect in the use of everyday and advanced technology across the four participant groups. However, it was found that age and living arrangements accounted for most of the variance in reported everyday technology use (p = .030; p = .029, respectively) and age and gender accounted for the variance in reported advanced technology use (p <.001; p = .040, respectively). For everyday technology, an increase in age and living alone were associated with decreased technology use and for advanced technology use, age and female gender were associated with decreased technology use. Conclusions: Although we hypothesized that technology use would be less amongst non-consulters and unsuccessful hearing aid owners, our findings did not support this prediction. Technology use did not vary by group membership once the covariates of age, gender, and living arrangements were accounted for.     

Cochrane corner: hearing aids for mild to moderate hearing loss in adults

This Cochrane corner features the review entitled “Hearing aids for mild to moderate hearing loss in adults” published in 2017. In their review, Ferguson et al. identified five randomised controlled trials (RCTs) involving 825 participants, with moderate quality of evidence shown for all domains except adverse effects. Results showed a large beneficial effect of hearing aids on hearing-specific health-related quality of life and listening ability, and a small yet significant beneficial effect on overall health-related quality of life. Ferguson et al. concluded that according to the available evidence, hearing aids are effective at improving hearing-specific health-related quality of life, general health-related quality of life and listening ability in adults with mild to moderate hearing loss. The evidence supports the widespread provision of hearing aids as the first-line clinical management for those seeking help for hearing difficulties.     

Prediction of the use of conventional hearing aids in Korean adults with unilateral hearing impairment

Objective: To determine the use of a hearing aid at six months post-fitting and to evaluate the predictors of its ongoing use in Korean adults with unilateral hearing impairment (HI). Design: Retrospective study at a secondary referral hospital over a 15-year period. Study sample: This study analysed 119 adults with unilateral HI who had been recommended for hearing amplification (55 men and 64 women, mean age, 58.0 ± 11.7 years). Six months after the fitting, all of the participants were surveyed regarding subsequent decisions and actions about obtaining hearing aids. Results: General uptake rate for a hearing aid was 68.1% (58.0% of participants surveyed were successful users, and 10.1% were intermittent users). The most significant parameter associated with hearing-aid use was social and/or work activities (R² = 0.457), and the significant predictors for successful hearing-aid use were social and/or work activities and method of signal processing (discriminatory power = 56.3%). Conclusions: Six months post-fitting, 68.1% of Korean adults with unilateral HI who had agreed to try a hearing aid continued to use it regularly. The predictors for hearing-aid use six months post-fitting included social and/or work activities and digital signal processing.     

Factors associated with hearing aid fitting outcomes on the IOI-HA

Abstract

A hallmark of quality clinical practice in audiology should be the ongoing measurement of outcomes in order to improve practice. The aims of this study were to describe outcomes for a large sample of clients fitted with hearing aids and to investigate factors associated with mean IOI-HA scores, with a view to providing guidance about factors that warrant particular attention in the clinic in order to improve outcomes. Measures used were the international outcome inventory – hearing aids (IOI-HA; ) and a series of questions about satisfaction with hearing aid performance in different listening situations, hearing aid attributes, and clinical service. The participant sample consisted of 1653 adults, most often fitted bilaterally (78%); 81% had digital aids with at least two listening programs. Results of the regression analysis indicated that there were a number of significant factors that, in total, explained 57% of the variance in IOI-HA scores. Higher mean IOI-HA scores were most strongly associated with greater satisfaction with hearing aid attributes of aid fit/comfort, clarity of tone and sound, and comfort with loud sounds and with satisfaction in the listening situations of conversation with one person, in small groups, in large groups, and outdoors. These findings highlight the importance of focusing rehabilitation on improving satisfaction with aided listening across a range of environments and with key attributes of hearing aid performance.

Sumario

El sello de calidad de la práctica clínica audiológica debería ser la medición continuada de los resultados para poder mejorar la práctica. Los objetivos de este estudio fueron describir los resultados de una amplia muestra de clientes adaptados con un auxiliar auditivo e investigar los factores asociados con puntuaciones IOI-HA promedio, con la intención de proporcionar una guía sobre los factores que justifican la atención particular en la clínica para mejorar los resultados. Las mediciones utilizadas fueron el inventario internacional de resultados – auxiliares auditivos (IOI-HA; ) y una serie de preguntas sobre satisfacción con el desempeño del auxiliar auditivo en diferentes situaciones auditivas, los atributos del auxiliar y el servicio clínico. La muestra de participantes consistió en 1653 adultos, en su mayoría con auxiliares auditivos bilaterales (78%); 81% tenían auxiliares digitales con al menos dos programas. Los resultados del análisis de regresión indicaron que hubo un número de factores significativos que en total explicaban el 57% de la varianza en los resultados de IOI-HA. Los resultados del IOI-HA altos en promedio estuvieron estrechamente asociados con una mayor satisfacción con los atributos del auxiliar auditivo como adaptación/confort y claridad del tono y sonido y confort con sonidos elevados y con la satisfacción en las situaciones de escucha de conversaciones con una persona, en grupos pequeños, en grupos grades y en el exterior. Estos hallazgos remarcan la importancia de enfocar la rehabilitación hacia el mejoramiento de la satisfacción con la audición asistida a través de un rango de ambientes y con los atributos clave del desempeño de los auxiliares auditivos.     

An Australian version of the acceptable noise level test and its predictive value for successful hearing aid use in an older population

Abstract

Objective: The acceptable noise level (ANL), a measure of noise tolerance, has been proposed as a predictor for successful hearing aid use. The aims of this study were to obtain normative data, and to evaluate the clinical feasibility and predictive value of an Australian version of the ANL test in an older population. Design: Repeated ANL measurements were presented diotically using earphones. All participants provided demographic information and hearing aid owners were asked about their aid use. Study sample: A total of 290 older adults were assessed; 166 participants had a hearing impairment and 96 owned a hearing aid. Results: The mean ANL was lower than previously reported. While age and gender had no effect on ANL, a significant, but weak, correlation was found between ANL and hearing loss. The test-retest reliability showed the results were clinically unreliable. In addition, the ANL did not predict hours or pattern of hearing aid use. Conclusions: While the Australian ANL test showed several similar characteristics to previous versions of the test, low test-retest reliability raised questions about its clinical value as a predictor for long-term hearing aid use.     

Autonomous motivation is associated with hearing aid adoption

Objective: To use the self-determination theory of motivation to investigate whether different forms of motivation were associated with adults’ decisions whether or not to adopt hearing aids. Design: A quantitative approach was used in this cohort study. Participants completed the treatment self-regulation questionnaire (TSRQ), which measured autonomous and controlled motivation for hearing aid adoption. Sociodemographic data and audiometric information were also obtained. Study sample: Participants were 253 adults who had sought information about their hearing but had not consulted with a hearing professional. Participants were categorized as hearing aid adopters if they had been fitted with hearing aids 4–6 months after completing the TSRQ, and as non-adopters if they had not. Results: Multivariate logistic regression was used to examine associations between autonomous and controlled motivation, sociodemographic and audiometric variables, and hearing aid adoption (n = 160). Three factors were significantly associated with increased hearing aid adoption when the influence of other variables was accounted for: autonomous motivation, perceived hearing difficulty, and poorer hearing. Controlled motivation was not found to influence hearing aid adoption. Conclusion: These empirical findings that link autonomous motivation to decisions of hearing help-seekers have implications for the ways practitioners may evaluate motivation and could inform discussions with clients about hearing aid adoption.     

Factors influencing rehabilitation decisions of adults with acquired hearing impairment

Abstract

Several rehabilitation interventions yielding comparable outcomes are available to adults with acquired hearing impairment. However, the reasons why people choose particular interventions and not others have not been systematically investigated. This study explored the factors influencing the rehabilitation decisions of adults with acquired hearing impairment. Four options (hearing aids, group communication program, individual communication program, and no intervention) were discussed using shared decision making with 153 adults with acquired hearing impairment who had not previously received hearing rehabilitation. A selected sub-sample of 22 participants described the factors that influenced their decision during a semi-structured interview. Using qualitative content analysis, seven categories of factors influencing rehabilitation decisions were identified: (1) convenience; (2) expected adherence and outcomes; (3) financial costs; (4) hearing disability; (5) nature of intervention; (6) other people's experiences, recommendations, and support; and (7) preventive and interim solution. All categories of factors were a positive influence for a particular intervention for some participants and a negative influence for the same intervention for other participants. The results support a client-centred approach to decision making.

Sumario

Existen varias intervenciones en rehabilitación que conducen a resultados comparables, disponibles para adultos con trastornos adquiridos de la audición. Sin embargo, las razones por las que la gente escoge un tipo de intervención particular y no otro, no han sido sistemáticamente investigadas. El estudio exploró los factores que influyen en las decisiones de rehabilitación de adultos con trastornos adquiridos de la audición. Cuatro opciones (auxiliares auditivos, programa de comunicación grupal, programas de comunicación individual y ninguna intervención) fueron discutidas usando una toma compartida de decisiones con 153 adultos con trastornos adquiridos de la audición, quienes no habían recibido rehabilitación auditiva previa.

Veintidós participantes de una sub-muestra seleccionada describieron los factores que influyeron en su decisión, por medio de una entrevista semi-estructurada. Utilizando un análisis cualitativo de contenido, se identificaron siete categorías de factores que influyen en las decisiones de rehabilitación: (1) conveniencia; (2) adherencia esperada y resultados; (3) costos financieros; (4) discapacidad auditiva; (5) naturaleza de la intervención; (6) las experiencias, recomendaciones y apoyo de otras personas, y (7) soluciones preventivas y provisionales. Todas las categorías de factores fueron una influencia positiva para cada intervención particular en algunos participantes y una influencia negativa para la misma intervención en otros participantes. Los resultados apoyan un enfoque centrado en el cliente para la toma de decisiones.     

Assessing hearing loss self-management in older adults

Objective: To evaluate the capacity of a self-management assessment tool to identify unmet hearing health care (HHC) needs; to determine whether such an assessment yields novel and clinically useful information. Design: Hearing loss self-management (HLSM) was assessed with the Partners in Health scale and the Cue and Response interview from the Flinders Chronic Condition Management Program?. The results of the scale and the interview were compared to determine the extent to which they each contributed to the assessment of HLSM. Study sample: Thirty older adults who currently receive HHC. Results: The two assessment tools were useful in identifying the specific domains in which participants lacked good HLSM skills. While participants tended to have a high level of knowledge about hearing loss and technology-based interventions, many reported the presence of unmet psychosocial needs with no clear plan for addressing them. There was considerable variation in terms of the extent to which their audiologists facilitated shared decision-making. Conclusions: The results suggest that HLSM has the potential to play an important role in audiological rehabilitation. A HLSM assessment tool that more precisely matches the unique needs of people with hearing loss should be developed, along with interventions to meet those needs.     

Prevalence and associated factors of hearing aid use among older adults in Chile

Objective: The aim of this study was to determine the prevalence of use of hearing aids by older adults in Chile and the influence of some variables such as education level, income level and geographic area of residence on the prevalence of hearing aids. Design: A national cross-sectional survey which was carried out in 2009. Study sample: A representative sample of 4766 Chilean older adults aged 60 years and above. Results: The percentage of older adults in Chile who self-reported hearing problems and used hearing aids was 8.9%. Such prevalence increased for adults living in urban areas and for those who knew about the new Chilean programme of universal access to health services (AUGE). For older adults who did not know about this programme, significant associations between the use of hearing aids and the variables of age, geographic area of residence, and income level were found. Conclusions: People’s knowledge about AUGE programme may positively influence the use of hearing aids, although a direct effect cannot be attributed.     

Predictors of aided speech recognition,with and without frequency compression,in older adults

Objective: The aim was to investigate whether cognitive and/or audiological measures predict aided speech recognition, both with and without frequency compression (FC). Design: Participants wore hearing aids, with and without FC for a total of 12 weeks (six weeks in each signal processing condition, ABA design). Performance on a sentence-in-noise recognition test was assessed at the end of each six-week period. Audiological (severity of high frequency hearing loss, presence of dead regions) and cognitive (reading span and trail making test scores) measures were obtained and assessed as predictors of sentence-in-noise recognition with and without FC enabled. Study sample: Twelve experienced hearing-aid users (aged 65–84 years old) with moderate-to-severe high-frequency hearing loss took part in the study. Results: The results suggest that both auditory and cognitive factors can be predictive of sentence-in-noise recognition with conventional amplification. However, only auditory factors were significantly correlated with the degree of benefit obtained from FC. Conclusions: The strongest predictor of aided speech recognition, both with and without FC, was high frequency hearing loss. Cognitive performance was also a predictor of benefit from conventional amplification, but not of additional benefit from the use of FC.     

Self-reported disability and handicap after hearing-aid fitting and benefit of hearing aids: comparison of fitting procedures, degree of hearing loss, experience with hearing aids and uni- and bilateral fittings

Self-reported outcome on hearing disability and handicap as well as overall health-related quality of life were measured after hearing-aid fitting in a large-scale clinical population. Fitting was performed according to two different procedures in a double-blind study design. We used a comparative procedure based on optimizing speech intelligibility scores and a strictly implemented fitting formula. Hearing disability and handicap were assessed with the hearing handicap and disability inventory and benefit of hearing aids with the abbreviated profile of hearing aid benefit. Effects on health-related quality of life and depression were assessed with the EuroQol-5D questionnaire and the geriatric depression scale. We found that hearing-aid fitting according to either procedure had a significantly positive effect on disability and handicap associated with hearing loss. This effect lasted for several months. Only the effect on disability persisted after 1-year of follow-up. Self-reported benefit from hearing aids was comparable for both fitting procedures. Unaided hearing disability was more pronounced in groups of participants with greater hearing loss, while the benefit of hearing aids was independent from the degree of hearing impairment. First-time hearing aid users reported greater benefit from their hearing aids. The added value from a bilateral hearing-aid fitting was not significant. Overall health-related quality of life and incidence of depression did not alter after hearing-aid fitting.     

Bone anchored hearing aids: a second fixture reduces auditory deprivation in Cambridge

Bone anchored hearing aids are well established for canal atresia, otosclerosis and chronic suppurative otitis media. Refinements in technique to maximise gain while keeping the complications to a minimum are desirable. This study was taken up in order to explore the potential advantage of a second or spare fixture placed at the time of primary surgery. A group of patients who underwent BAHA insertion at The Emmeline Centre for Cochlear Implants and Bone Anchored Hearing Aids, Addenbrookes hospital, Cambridge, UK with the placement of a spare fixture between 1999 and 2002 were compared to those patients with one fixture BAHA undertaken from 1991. Main outcome measures were complications encountered and duration of disability, (i.e. loss of hearing while waiting for new fixture placement). Both groups had similar incidence of complications, but the group with two fixtures suffered a shorter period of disability when a fixture failed. In our experience the use of second or spare fixture reduces the duration of disability. It engenders no additional complications with minimal extra cost. This paper was presented at 24th Politzer society meeting, Amsterdam, September 2003.     

Use of technological aids and interpretation services among children and adults with hearing loss

Objectives: The technological development of communication aids for people with hearing loss has progressed rapidly over the last decades. Quality has improved and the number of different types of aids has increased. However, few studies have examined the prevalence of technology use and interpreting services use among people with hearing loss as they relate to demographic characteristics of this population. Design: This study reports from national surveys of children and adults with hearing loss. Use of hearing aids, cochlear implants, other aids and interpreting services were analysed with regard to gender, age, degree of hearing loss, mode of communication, having an additional disability, level of educational achievement among adults, and whether or not children lived together with both of their parents. Study sample: 269 children (0–15 years of age) and 839 adults (16–65 years of age). Results: Differences in technology and service use were associated with age, degree of hearing loss, and mode of communication among children and adults, and gender and level of educational achievement among adults. Conclusion: Individual and social factors have an impact on technological hearing aid and interpreter use. More research about individual differences and clinical implications of support services is needed.     

The role of bone anchored hearing aids in children with Down syndrome

OBJECTIVES: To evaluate complication rates and outcomes of children with Down syndrome fitted with a Bone Anchored Hearing Aid (Baha). To evaluate whether the Bone Anchored Hearing Aid is a successful form of aural rehabilitation in children with Down syndrome from a patients' perspective. STUDY DESIGN: Retrospective case analysis and postal questionnaire study. SETTING: The Birmingham Children's Hospital, UK. METHODS: A total of 15 children were fitted with a Baha between February 1992 and February 2007. The age range was 2-15 years. A postal questionnaire was sent to each family. The Glasgow Children's Benefit Inventory (GCBI) was used in this study. OUTCOME MEASURES: Implantation results, skin reactions and other complications were recorded. Quality of life after receiving a Baha was assessed with the GCBI. RESULTS: All 15 patients are using their Baha 7 days a week for more than 8h a day after a follow-up of 14 months with continuing audiological benefit. No fixtures were lost, and skin problems were encountered in 3 (20%). Regarding quality of life, all 15 patients had improved social and physical functioning as a result of better hearing. CONCLUSIONS: Baha has an important role in the overall management of individuals with Down syndrome after conventional hearing aids and/or ventilation tubes have been considered or already failed. This study has shown a 20% rate of soft tissue reaction and there were no fixture losses in this group. No significant increase in complication rates was identified in children with Down syndrome. Finally, there was a significantly improved quality of life in children with Down syndrome after receiving their Baha. There was a high patient/carer satisfaction with Baha. Two of our series had bilateral two stage fixture procedures without any complications. More consideration should be given to bilateral bone anchored hearing aids in this group.     

Children with hearing impairment--living with cochlear implants or hearing aids

Objective

The aim of this study was to enhance knowledge about the life circumstances of children with cochlear implants or hearing aids, regarding daily functioning and attitude to the impairment.

Methods

Data were obtained from 36 children with cochlear implants and 38 children with hearing aids via study-specific questionnaires with fixed answer alternatives. The questions covered (1) usage of aids and related factors, (2) hearing in different everyday situations, (3) thoughts about the children's own hearing and others’ attitudes to it, and (4) choice of language. The data were analyzed using SPSS, and presented via the theoretical frame of the International Classification of Functioning, Disability and Health, Child and Youth version (ICF-CY).

Results

Children with CI and HA functioned equally well in daily life, but there were also certain differences. Symptoms from neck and shoulders were more common among children with hearing aids than among children with cochlear implants (p < .001). Children with hearing aids used their aids significantly less often than those with cochlear implants (p < .001). The participation variables showed that children with hearing aids had significantly more hearing problems in team sports (p = .033) and outdoor activities (p = .019), in comparison to children with cochlear implants. The two groups had similar thoughts regarding their own hearing, mostly considering it not to be a problem. They also did not generally think that other people found their hearing to be a problem.

Conclusions

Children with cochlear implants and children with hearing aids have, in some aspects, equally good functioning in everyday life situations. However, certain differences were found in dimensions of functioning, regarding neck and shoulder pain, usage of aids and sign language, and hearing problems in some activities.
