Hearing loss and falls: A systematic review and meta-analysis

Evaluation of Hearing Loss: Understanding Audiologic Testing to Refine Image Interpretation

The standard of reference for diagnosing and characterizing hearing loss is audiologic testing. The results of audiologic testing inform the imaging algorithm and the differential diagnosis for the underlying cause. Pure-tone audiometry tests the ability to hear tones across different frequencies, and the results are displayed as an audiogram. Tympanometry measures tympanic membrane compliance as a function of pressure to generate a tympanogram. Acoustic reflex testing helps differentiate third window lesions from other causes of conductive hearing loss. Clinical and audiologic assessment of sensorineural hearing loss helps in differentiating cochlear from retrocochlear causes. Symmetrical sensorineural hearing loss is typical of cochlear disease. Asymmetry increases the likelihood of a retrocochlear lesion, the most common of which among adults is vestibular schwannoma. Unlike patients with sensorineural hearing loss, who commonly have normal imaging studies, patients with conductive hearing loss are expected to have abnormal temporal bone CT studies. By incorporating the results of audiologic testing into their evaluation, radiologists can perform a more informed and more intentional search for the structural cause of hearing loss. The authors describe several audiogram configurations that suggest specific underlying mechanisms of conductive hearing loss. By providing a practical and accessible summary of the basics of audiologic testing, the authors empower the radiologist to leverage relevant clinical information and audiologic test results to interpret temporal bone imaging more confidently and more accurately, particularly temporal bone CT in the setting of conductive hearing loss. ©RSNA, 2024.

The Medicare annual wellness visit: An opportunity to improve health system identification of hearing loss?

BACKGROUND

Hearing loss is prevalent and consequential but under-diagnosed and managed. The Medicare Annual Wellness Visit (AWV) health risk assessment elicits patient-reported hearing concerns but whether such information affects documentation, diagnosis, or referral is unknown.

METHODS

We use 5 years of electronic medical record (EMR) data (2017-2022) for a sample of 13,776 older primary care patients. We identify the first (index) AWV indication of hearing concerns and existing and subsequent hearing loss EMR diagnoses (visit diagnoses or problem list diagnoses) and audiology referrals. For a 20% random sample of AWV notes (n = 474) we compared hearing loss EMR diagnoses to documentation of (1) hearing concerns, (2) hearing loss/aid use, and (3) referrals for hearing care.

RESULTS

Of 3845 (27.9%) older adults who identified hearing concerns (mean age 79.1 years, 57% female, 75% white) 24% had an existing hearing diagnosis recorded. Among 474 patients with AWV clinical notes reviewed, 90 (19%) had an existing hearing loss diagnosis. Clinicians were more likely to document hearing concerns or hearing loss/aid use for those with (vs. without) an existing EMR diagnosis (50.6% vs. 35.9%, p = 0.01; 68.9% vs. 37.5%, p < 0.001, respectively). EMR diagnoses of hearing loss were recorded for no more than 40% of those with indicated hearing concerns. Among those without prior diagnosis 38 (9.9%) received a hearing care referral within 1 month. Subgroup analysis suggest greater likelihood of documenting hearing concerns for patients age 80+ (OR:1.51, 95% confidence interval [CI]: 1.03, 2.19) and decreased likelihood of documenting known hearing loss among patients with more chronic conditions (OR: 0.49, 95% CI: 0.27, 0.9), with no differences observed by race.

CONCLUSION

Documentation of hearing loss in EMR and AWV clinical notes is limited among older adults with subjective hearing concerns. Systematic support and incorporation of hearing into EMR and clinical notes may increase hearing loss visibility by care teams.

Demographic Disparities in Drive Times to the Nearest Audiologist in the United States

PURPOSE

Audiological services are underused, possibly because patients need to drive long distances to see a provider. In this study, we measured the association of drive times to the nearest audiologist with population density, income, ethnicity, race, and distance to the nearest audiology graduate program.

METHOD

Drive times for each census block group to the nearest audiologist were measured using census data, the National Provider Identifier Registry, and a geographic analyzing tool called ArcGIS for all block groups within the United States. The association between drive times and population density, income, ethnicity, race, and audiology program distance was evaluated with a population density-matched case-control study and multiple linear regression analyses.

RESULTS

Approximately 5.29 million Americans need to drive at least 1 hr to visit their closest audiologist. The 10% most rural-dwelling Americans drive an average of 33.8 min. The population density-matched case-control study demonstrated that percent below poverty, percent identifying as Hispanic, and travel times to the nearest audiology program were all significantly higher in census block groups with high drive times to the nearest audiologist. An average of 7.96% of individuals in census block groups with low drive times identified as Hispanic, but 18.8% identified as Hispanic in high drive time groups. The multiple linear regression showed that the effect of demographics and distance to the nearest audiology program was highest in rural areas. In both analyses, adjusting for poverty did not drastically change the effect of percent identifying as Hispanic on drive times.

CONCLUSIONS

Long drive times restrict access to audiological care for those who live in rural areas. This restriction disproportionately affects those in rural areas who identify as Hispanic or have low income.

Associations between hearing loss, peripheral neuropathy, balance, and survival in older primary care patients

BACKGROUND

Both age-associated hearing loss (AAHL) and peripheral neuropathy (PN) are common in older patients, and both are associated with impaired balance, falls, and premature mortality. The objectives of this study were to document the prevalence and severity of AAHL in older primary care patients, and to explore associations between AAHL, PN, balance, falls, and mortality.

METHODS

We analyzed information obtained in 1999 from 793 primary care patients recruited from practices participating in the Oklahoma Longitudinal Assessment of the Health Outcomes of Mature Adults (OKLAHOMA) Studies. Available data included demographic and health information, history of falls and hospitalizations, audiometry, balance testing, examination of the peripheral nerves, 50 foot timed gait, and dates of death up to 22 calendar years and 8106 person-years of follow-up. Proportionate hazards (PH) and structural equation modeling (SEM) were used to examine associations between AAHL, PN, balance, gait time, and mortality.

RESULTS

501 of the 793 participants (63%) had AAHL. Another 156 (20%) had low frequency and 32 (4%) had unilateral deficits. Those with moderate or severe AAHL and the 255 (32%) with PN had impaired balance (p < 0.0001), increased gait time (p = 0.0001), and reduced survival time (p < 0.0001). In the PH model, both AAHL and PN were associated with earlier mortality (H.Rs. [95% C.I.]: 1.36 [1.13-1.64] and 1.32 [1.10-1.59] respectively). The combination of moderate or severe AAHL and PN, present in 24% of participants, predicted earlier mortality than predicted by either deficit alone (O.R. [95% C.I.I] 1.55 [1.25-1.92]). In the SEM models, the impacts of both moderate or severe AAHL and PN on survival were mediated, in part, through loss of balance.

CONCLUSIONS

Hearing loss and PN, both common in older patients, appear to be independently and additively associated with premature mortality. Those associations may be mediated in part by impaired balance. The Mechanisms are likely multiple and complex.

Associations of frailty, self-reported balance problems, hearing abilities, and posturography in a sample of older adults

OBJECTIVE

The aim of this study was to identify risk factors for self-reported balance problems, and to analyse associations between hearing and balance.

DESIGN

A battery of tests was administered to assess hearing and balance performance, as well as additional health-related factors indicative of frailty and fall risk. In a retrospective analysis, logistic regression was used to identify risk factors for self-reported balance problems and linear regression was used to identify associations between hearing ability and functional balance.

STUDY SAMPLE

For the risk factor analysis, 199 volunteers aged 55-81 years (mean:67) were divided into two groups according to their self-reported balance problems. Only participants lacking self-reported balance problems (n = 157) were included in the second analysis.

RESULTS

Female gender, frailty, and fine-motor skills were statistically significant predictors of self-reported balance problems. Functional balance performance was related to hearing impairment for dynamic, but not for static, balance tasks.

CONCLUSION

For a holistic approach to healthcare and regardless of age, individuals with multiple comorbidities and/or phenotypic signs of frailty should be considered at risk for falls. For further research, it was shown that dynamic, rather than static, balance tasks may be needed to gain deeper insights into the relationship between hearing and balance.

Dual- and Single-Task Training in Older Adults With Age-Related Hearing Loss: A Randomized Controlled Study

We aimed to investigate the effects of dual- and single-task training in older adults with age-related hearing loss. Intervention groups included single-, dual-task training, and control groups. The dual- and single-task trainings were held 2 days a week for 40 min for a total of 10 sessions for 5 weeks. We evaluated physical, cognitive, and auditory functions, quality-of-life, balance, concerns about falling, independence in activities of daily living, and dual-task performance. A total of 42 patients fully participated in this study. Statistically significant differences were observed in chair stand, chair sit-and-reach, global cognitive function, and delayed recall between the intervention groups and control group (p < .05). There was no statistically significant difference in quality-of-life, balance, falling concerns, independence in activities of daily living, and dual-task performance between all groups (p > .05). In conclusion, single- and dual-task training had a positive effect on physical and cognitive functioning in older adults with age-related hearing loss.

The Effect of Cochlear Implant Stimulation on Postural Control

Objective

There are contradictory reports on the effect of cochlear implantation on postural control. Associated vestibular loss, electrode insertion trauma, and electrical stimulus of a cochlear implant can influence postural control. This study focused on the electrical stimulation of the cochlea. We aimed to examine whether a cochlear implant's electrical stimulation affects postural control measured by posturography.

Methods

Thirty-three patients with unilateral cochlear implants were included. We used three preprogrammed main tests and their nine subtests in posturography. Postural stability [general stability index (GSI)], fall risk index (FRI), and sensory integration [modified clinical test of sensory integration of balance (m-CTSIB)] were calculated. All tests were performed under three conditions: implant off (1), implant on (2), and implant on music (3).

Results

The mean age was 46.29±16.09 years. GSI was above normal limits in 78% of adult cochlear implant users. We found that FRI was high in 30% of patients, and m-CTSIB was defective in 42%. There were no statistically significant differences in GSI, FRI, and m-CTSIB. Cochlear implant stimulation was found to have positively affected postural control when the subject's data were visualized individually. GSI, FRI, and m-CTSIB dropped to 39%, 24%, and 24%, respectively, when music was on. There was a significant correlation between age and fall index. But this correlation disappeared when music was playing.

Conclusion

Cochlear implant stimulation affected the vestibular system in almost all patients. The effect was positive in most patients.

Hearing Impairment and Physical Activity and Physical Functioning in Older Adults: Baseline Results From the ACHIEVE Trial

BACKGROUND

Hearing loss is associated with restricted physical activity (PA) and impaired physical functioning, yet the relationship between severity of hearing impairment (HI) and novel PA measures in older adults with untreated HI is not well understood.

METHODS

Analyses included 845 participants aged ≥70 years (mean = 76.6 years) with a better-hearing ear pure-tone average (PTA) ≥30 and <70 dB in the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) study who wore an ActiGraph accelerometer for 7 days. Physical functioning measures included grip strength and the Short Physical Performance Battery (SPPB). Linear regression models estimated the association by HI level (moderate or greater [PTA ≥ 40 dB] vs mild [PTA < 40 dB]) and continuous hearing with total daily activity counts, active minutes/day, activity fragmentation, grip strength, and gait speed. Logistic regression models estimated odds ratios (ORs) and 95% confidence intervals (CIs) of poor performance on the SPPB (≤6) and its subtests (≤2). Mixed-effects models estimated differences by HI level in activity by time of day.

RESULTS

Participants with moderate or greater HI had poorer physical functioning, particularly balance (OR = 2.17, 95% CI = 1.29-3.67), versus those with mild impairment. There was no association of HI level with activity quantities or fragmentation. For diurnal patterns of activity, participants with moderate or greater HI had fewer activity counts in the afternoon (12:00 pm -05:59 pm).

CONCLUSIONS

Older adults with worse hearing had shifted diurnal patterns and poorer balance performance. Exercise programs should be tailored to older adults with different levels of HI to maintain PA and physical functioning, particularly balance control.

Comparison of postural control and space perception outcomes between robotic and conventional cochlear implantation in adults

PURPOSE

The aim of the study is to capture the difference between the groups in direct relation to the type of electrode array insertion during cochlear implantation (CI). The robotic insertion is expected to be a more gently option. As recent studies have shown, there is a difference in perception of visual vertical (SVV) and postural control related to the CI. We assume that there can be differences in postural control and space perception outcomes depending on the type of the surgical method.

METHODS

In total, 37 (24 females, mean age ± SD was 42.9 ± 13.0) candidates for CI underwent an assessment. In 14 cases, the insertion of the electrode array was performed by a robotic system (RobOtol, Colin, France) and 23 were performed conventionally. In all of these patients, we performed the same examination before the surgery, the first day, and 3 weeks after the surgery. The protocol consists of static posturography and perception of visual vertical.

RESULTS

The both groups, RobOtol and conventional, responded to the procedure similarly despite the dissimilar electrode insertion. There was no difference between two groups in the dynamic of perception SVV and postural parameters. Patients in both groups were statistically significantly affected by the surgical procedure, SVV deviation appeared in the opposite direction from the implanted ear: 0.90° ± 1.25; - 1.67° ± 3.05 and - 0.19° ± 1.78 PRE and POST surgery (p < 0.001). And this deviation was spontaneously adjusted in FOLLOW-UP after 3 weeks (p < 0.01) in the both groups. We did not find a significant difference in postural parameters between the RobOtol and conventional group, even over time.

CONCLUSION

Although the robotic system RobOtol allows a substantial reduction in the speed of insertion of the electrode array into the inner ear, our data did not demonstrate a postoperative effect on vestibular functions (SVV and posturography), which have the same character and dynamics as in the group with standard manual insertion.

REGISTRATION NUMBER

The project is registered on clinicaltrials.gov (registration number: NCT05547113).

Objective physical function declines in the absence of subjective physical complaints among patients with amnestic mild cognitive impairments and mild alzheimer's disease

PURPOSE

To examine the extent to which patients with amnestic mild cognitive impairment (aMCI) or Alzheimer's disease (AD) perceive their own physical decline.

METHODS

This study included 4450 outpatients (1008 normal cognition [NC], 1605 aMCI, and 1837 mild AD) who attended an initial visit to a memory clinic between July 2010 and June 2021. Their physical function was assessed by the Timed Up and Go test, one-leg standing test, and grip strength. For physical complaints, data were obtained on reports of fear of falling and dizziness or staggering. Logistic regression analysis was performed to compare the patients' physical function and complaints for each stage of NC, aMCI, and mild AD.

RESULTS

Objective physical function declined from aMCI and the mild AD stage, but subjective physical complaints decreased by 20-50% in aMCI and 40-60% in mild AD compared with the NC group.

CONCLUSION

As objective physical functional declined from the aMCI stage onward, subjective physical complaints decreased. This suggests a need for objective assessment of physical function in aMCI and mild AD patients even when they have no physical complaints in the clinical setting.

Association of Single and Dual Sensory Impairment with Falls among Medicare Beneficiaries

Objective: The purpose of this study was to determine if dual sensory impairment (DSI) is associated with falls and fear of falling among older adults. Methods: Using data from the 2019 Medicare Current Beneficiary Survey (MCBS), we studied the cross-sectional association of self-reported hearing/vision impairment with self-reported history/number of falls over the past year, fear of falling (scale 1-6), and a fall requiring medical help using weighted multivariable regressions adjusted for demographic and clinical covariates. Results: Among 11,089 Medicare beneficiaries (mean age = 74, 55% female, 9% Black), DSI is associated with increased prevalence (prevalence ratio = 1.45 [1.28-1.65]) and incidence (incidence ratio = 2.21 [1.79-2.75]) rate of falls, and greater odds of a higher fear of falling score (odds ratio = 1.38 [1.08-1.77]). Discussion: DSI is associated with falls among older adults. Consideration of DSI as a marker to initiate fall prevention programs and inclusion of sensory interventions in these programs may be valuable.

[Hearing in the elderly: Employees' perspectives on hearing care in long-term care facilities. A qualitative study]

Hearing in the elderly: Employees' perspectives on hearing care in long-term care facilities. A qualitative study Abstract: Background: Hearing impairment is common among the elderly. More than half of individuals 80 years and older exhibit severe hearing loss, and few retain good hearing performance. This impairment significantly affects both community participation and nursing care. Aim: This study aimed to examine the impact of hearing impairment on everyday life of employees and residents at long-term care facilities. We further sought to identify how employees perceive hearing care in order to identify potential for improvement. Methods: This sub-project of a larger study comprised guided focus groups with employees of long-term care facilities. The sample included six focus groups of nurses and nursing care assistants from long-term care facilities (n = 42). Collected data were analyzed using qualitative content analysis. Results: Hearing impairment hinders elderly resident participation in the nursing process and complicates daily communication between residents and nursing staff. Hearing impaired residents are less able to take part in group activities and tend to withdraw from the community. Lack of an effective hearing support structure renders hearing care services inaccessible to some residents. Conclusions: Optimized service structures, targeted assistance and training opportunities for employees specific to hearing impairment can provide sustainable hearing care for the elderly.

The lived experience of hearing loss - an individualised responsibility

OBJECTIVE

This study aimed to provide a conceptual model to understand what typifies the lived experience of hearing loss.

DESIGN

A grounded theory informed study of adults with hearing loss (n = 46) who participated in individual interviews. The data were analysed in line with the constant comparative approach of grounded theory. A substantial patient and public engagement (PPIE) strategy underpinned decisions and processes throughout.

STUDY SAMPLE

Adults were recruited from age bands (16-29; 30-49;50-79 and 80 upwards) to provide different lived experience. We recruited individuals from across the UK including urban, sub-urban and rural communities and included a typical constituency of each location including black and minority ethnic participants. Our PPIE groups included adults often marginalised in research including South Asian community groups, adults in residential care and those with additional disabilities.

RESULTS

We identified the consistent features of the lived experience with hearing loss, as the individualised responsibility that hearing loss confers. These are an individual auditory lifeworld; social comparison and social support; individual and patient-centred care and individual agency and capability.

CONCLUSIONS

This work provides new insights for those practising audiology and highlights the importance of building social support systems through implementation of family and peer support approaches.

Clinical Practice Guideline: Age-Related Hearing Loss

OBJECTIVE

Age-related hearing loss (ARHL) is a prevalent but often underdiagnosed and undertreated condition among individuals aged 50 and above. It is associated with various sociodemographic factors and health risks including dementia, depression, cardiovascular disease, and falls. While the causes of ARHL and its downstream effects are well defined, there is a lack of priority placed by clinicians as well as guidance regarding the identification, education, and management of this condition.

PURPOSE

The purpose of this clinical practice guideline is to identify quality improvement opportunities and provide clinicians trustworthy, evidence-based recommendations regarding the identification and management of ARHL. These opportunities are communicated through clear actionable statements with explanation of the support in the literature, evaluation of the quality of the evidence, and recommendations on implementation. The target patients for the guideline are any individuals aged 50 years and older. The target audience is all clinicians in all care settings. This guideline is intended to focus on evidence-based quality improvement opportunities judged most important by the guideline development group (GDG). It is not intended to be a comprehensive, general guide regarding the management of ARHL. The statements in this guideline are not intended to limit or restrict care provided by clinicians based on their experience and assessment of individual patients.

ACTION STATEMENTS

The GDG made strong recommendations for the following key action statements (KASs): (KAS 4) If screening suggests hearing loss, clinicians should obtain or refer to a clinician who can obtain an audiogram. (KAS 8) Clinicians should offer, or refer to a clinician who can offer, appropriately fit amplification to patients with ARHL. (KAS 9) Clinicians should refer patients for an evaluation of cochlear implantation candidacy when patients have appropriately fit amplification and persistent hearing difficulty with poor speech understanding. The GDG made recommendations for the following KASs: (KAS 1) Clinicians should screen patients aged 50 years and older for hearing loss at the time of a health care encounter. (KAS 2) If screening suggests hearing loss, clinicians should examine the ear canal and tympanic membrane with otoscopy or refer to a clinician who can examine the ears for cerumen impaction, infection, or other abnormalities. (KAS 3) If screening suggests hearing loss, clinicians should identify sociodemographic factors and patient preferences that influence access to and utilization of hearing health care. (KAS 5) Clinicians should evaluate and treat or refer to a clinician who can evaluate and treat patients with significant asymmetric hearing loss, conductive or mixed hearing loss, or poor word recognition on diagnostic testing. (KAS 6) Clinicians should educate and counsel patients with hearing loss and their family/care partner(s) about the impact of hearing loss on their communication, safety, function, cognition, and quality of life (QOL). (KAS 7) Clinicians should counsel patients with hearing loss on communication strategies and assistive listening devices. (KAS 10) For patients with hearing loss, clinicians should assess if communication goals have been met and if there has been improvement in hearing-related QOL at a subsequent health care encounter or within 1 year. The GDG offered the following KAS as an option: (KAS 11) Clinicians should assess hearing at least every 3 years in patients with known hearing loss or with reported concern for changes in hearing.

Association Between Hearing Difficulty and Mobility in Adults of All Ages: National Health Interview Survey

OBJECTIVE

To investigate the relationship between hearing difficulty and measures of mobility for US adults.

STUDY DESIGN

Cross-sectional study.

SETTING

2021 National Health Interview Survey.

METHODS

The survey asked US adults about hearing difficulty and mobility measures, including difficulty walking 100 yards, difficulty climbing 12 steps, and injury from falling within the past 3 months. Multivariable logistic regressions examined the associations between hearing and mobility outcomes, controlling for visual difficulty, medical comorbidities, and various demographic characteristics (age [18-39, 40-64, 65+], race/ethnicity, sex, socioeconomic status).

RESULTS

The 2021 NHIS surveyed 29,467 adults, representing 253 million people in weighted responses (52% female; mean age 48.3, standard deviation = 18.6). Controlling for covariates, hearing difficulty was associated with increased odds of difficulty walking 100 yards (odds ratio, OR = 1.47, P < .001), difficulty climbing stairs (OR = 1.62, P < .001), and injury from falling in the past 3 months (OR = 1.51, P < .001). There was a significant interaction between age and hearing difficulty for injurious falls; stratifying by age revealed that younger adults (ages 18-39) with hearing difficulty were more likely to report recent harmful falls than their normal hearing peers; this increased risk was greater in magnitude than that observed comparing older adults with and without hearing difficulty.

CONCLUSION

The hearing difficulty is associated with worsened mobility for US adults and may be a stronger independent predictor of injury from falls for younger adults as compared to older adults. These findings can inform interventions to reduce the burden of declining mobility in adults with hearing difficulty.

Hearing loss and cognitive decline: Prioritizing equity in a world in which hearing health matters

Alzheimer's disease and related dementias (ADRDs) and age-related hearing loss are the intersection of two major public health challenges. With age as the primary risk factor for both disease processes, the burden of ADRDs and age-related hearing loss is growing, and each field maintains significant barriers to broadscale identification and management that is affordable and accessible. With the disproportionate burden of ADRDs among racial and ethnic minority older adults and existing disparities within hearing care, both areas face challenges in achieving equitable access and outcomes across diverse populations. The publication of the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) trial in July 2023 marked a significant moment in the fields of brain and hearing health. The ACHIEVE trial was the first randomized controlled trial to examine whether providing hearing intervention, specifically provision of hearing aids, compared to an education control, would reduce cognitive changes over 3 years. The participants most at risk for cognitive decline, with lower education, lower income, more likely to identify as Black, and have more cardiovascular risk factors, were the participants who benefited most from the hearing intervention and are also the least likely to be represented in research and the least likely to obtain hearing care. With growing evidence of the interconnection between cognitive and sensory health, we have an opportunity to prioritize equity, from purposeful inclusion of diverse participants in trials to influencing the emerging market of over-the-counter hearing aids to supporting expanded models of hearing care that reach those who have traditionally gone unserved. No longer can hearing go unrecognized by clinicians, researchers, and advocates for brain health. At the same time, the fields of brain and hearing health must center equity if we are going to meet the needs of diverse older adults in a world in which hearing health matters.

Ten-year association between change in speech-in-noise recognition and falls due to balance problems: a longitudinal cohort study

BACKGROUND

This study examined the relationship between speech-in-noise recognition and incident/recurrent falls due to balance problems ten years later (RQ-1); 10-year change in speech-in-noise recognition and falls (RQ-2a), as well as the role of dizziness in this relationship (RQ-2b). The association between hearing aid use and falls was also examined (RQ-3).

METHODS

Data was collected from the Netherlands Longitudinal Study on Hearing between 2006 and December 2022. Participants completed an online survey and digits-in-noise test every five years. For this study, data was divided into two 10-year follow-up time intervals: T0 (baseline) to T2 (10-year follow-up), and T1 (5-years) to T3 (15-years). For all RQs, participants aged ≥ 40 years at baseline, without congenital hearing loss, and non-CI users were eligible (n = 592). Additionally, for RQ-3 participants with a speech reception threshold in noise (SRTn) ≥ -5.5 dB signal-to-noise ratio were included (n = 422). Analyses used survey variables on hearing, dizziness, falls due to balance problems, chronic health conditions, and psychosocial health. Logistic regressions using General Estimating Equations were conducted to assess all RQs.

RESULTS

Among individuals with obesity, those with poor baseline SRTn had a higher odds of incident falls ten years later (odds ratio (OR):14.7, 95% confidence interval (CI) [2.12, 103]). A 10-year worsening of SRTn was significantly associated with a higher odds of recurrent (OR: 2.20, 95% CI [1.03, 4.71]) but not incident falls. No interaction was found between dizziness and change in SRTn. Hearing aid use (no use/ < 2 years use vs. ≥ 2 years) was not significantly associated with incident nor recurrent falls. Although there was a significant interaction with sex for this association, the effect of hearing aid use on incident/recurrent falls was not statistically significant among males nor females.

CONCLUSIONS

A longitudinal association between the deterioration in SRTn and recurrent falls due to balance problems after 10 years was confirmed in this study. This result stresses the importance of identifying declines in hearing earlier and justifies including hearing ability assessments within fall risk prevention programs. Mixed results of hearing aid use on fall risk warrant further investigation into the temporality of this association and possible differences between men and women.

Establishing multifactorial risk factors for adult-onset hearing loss: A systematic review with topic modelling and synthesis of epidemiological evidence

BACKGROUND

This systematic review explores the multifaceted nature of risk factors contributing to adult-onset HL. The objective was to synthesise the most recent epidemiological evidence to generate pooled proportional incidences for the identified risk factors.

METHODS

We conducted an extensive search of electronic databases (MEDLINE, EMBASE, and psychINFO) for studies providing epidemiological evidence of risk factors associated with hearing loss. Topic modelling using Latent Dirichlet Allocation (LDA) was first conducted to determine how many risk factor themes were available from the papers. Data were analysed by calculating the pooled proportional incidence using a meta-analysis of proportions.

RESULTS

From the 72 studies reviewed, six key risk factor themes emerged through LDA topic modelling. The review identified ototoxicity, primarily caused by cancer treatments and antibiotics, infectious diseases like COVID-19, occupational noise exposure, lifestyle factors, health conditions, biological responses, and age progression as significant risk factors for HL. The highest proportional incidence was found with cancer-related ototoxicity at 55.4% (95%CI: 39.0-70.7), followed closely by ototoxicity from infectious diseases at 50.0% (95%CI: 28.5-71.5). This high proportional incidence suggests the need to explore less destructive therapies and proactively monitor hearing function during treatments.

CONCLUSIONS

The findings of this review, combined with the synthesis of epidemiological evidence, enhance our understanding of hearing loss (HL) pathogenesis and highlight potential areas for intervention, thereby paving the way for more effective prevention and management of adult-onset hearing loss in our ageing global population.

Hospitalizations, Emergency Department Visits, and Home Health Use Among Older Adults With Sensory Loss

Objectives: This study examines healthcare resource use (hospitalizations, emergency department [ED] visits, and home health episodes) among adults 65 and older diagnosed with hearing, vision, or dual sensory loss (SL) seen in the primary care setting of an academic health system. Methods: Multivariable logistic regression models were used to examine the relationship between SL (identified using ICD-10 codes) and healthcare resource use for 45,000 primary care patients. Results: The sample included 5.5% (N = 2479) with hearing loss, 10.4% (N = 4697) with vision loss, and 1.0% with dual SL (N = 469). Hearing loss increased the likelihood of having an ED visit (OR = 1.22, CI: 1.07-1.39), and home health services (OR = 1.27, CI: 1.07-1.51) compared to older adults without any SL. Vision loss reduced the likelihood of having a hospitalization (OR = .81, CI: .73-.91). Discussion: Findings support research into the drivers of healthcare use among older adults with sensory loss.

A Perspective on Auditory Wellness: What It Is, Why It Is Important, and How It Can Be Managed

During the last decade, there has been a move towards consumer-centric hearing healthcare. This is a direct result of technological advancements (e.g., merger of consumer grade hearing aids with consumer grade earphones creating a wide range of hearing devices) as well as policy changes (e.g., the U.S. Food and Drug Administration creating a new over-the-counter [OTC] hearing aid category). In addition to various direct-to-consumer (DTC) hearing devices available on the market, there are also several validated tools for the self-assessment of auditory function and the detection of ear disease, as well as tools for education about hearing loss, hearing devices, and communication strategies. Further, all can be made easily available to a wide range of people. This perspective provides a framework and identifies tools to improve and maintain optimal auditory wellness across the adult life course. A broadly available and accessible set of tools that can be made available on a digital platform to aid adults in the assessment and as needed, the improvement, of auditory wellness is discussed.

Purpose in Life and Risk of Falls: A Meta-Analysis of Cross-Sectional and Prospective Associations

Background and Aim: Purpose in life is an aspect of well-being that is associated with better health outcomes in older adulthood. We examine the association between purpose in life and likelihood of a recent fall and risk of an incident fall over time. Methods: Purpose in life and falls were reported concurrently and falls were reported again up to 16 years later in four established longitudinal studies of older adults (total N = 25,418). Results: A random-effects meta-analysis of the four samples indicated that purpose was associated with a 14% lower likelihood of having fallen recently at baseline (meta-analytic OR = 0.88, 95% CI [0.84-0.92]). Among participants who reported no falls at baseline (N = 15,632), purpose was associated with a nearly 10% lower risk of an incident fall over the up to 16-year follow-up (meta-analytic HR = 0.92, 95% CI [0.90-0.94]). These associations were independent of age, sex, race, ethnicity, and education, were not moderated by these factors, and persisted controlling for physical activity and disease burden. Conclusion and Recommendations: Purpose in life is a meaningful aspect of well-being that may be useful to identify individuals at risk for falling, particularly among individuals without traditional risk factors, and be a target of intervention to reduce fall risk.

Optimizing age-related hearing risk predictions: an advanced machine learning integration with HHIE-S

OBJECTIVES

The elderly are disproportionately affected by age-related hearing loss (ARHL). Despite being a well-known tool for ARHL evaluation, the Hearing Handicap Inventory for the Elderly Screening version (HHIE-S) has only traditionally been used for direct screening using self-reported outcomes. This work uses a novel integration of machine learning approaches to improve the predicted accuracy of the HHIE-S tool for ARHL in older adults.

METHODS

We employed a dataset that was gathered between 2016 and 2018 and included 1,526 senior citizens from several Taipei City Hospital branches. 80% of the data were used for training (n = 1220) and 20% were used for testing (n = 356). XGBoost, Gradient Boosting, and LightGBM were among the machine learning models that were only used and assessed on the training set. In order to prevent data leakage and overfitting, the Light Gradient Boosting Machine (LGBM) model-which had the greatest AUC of 0.83 (95% CI 0.81-0.85)-was then only used on the holdout testing data.

RESULTS

On the testing set, the LGBM model showed a strong AUC of 0.82 (95% CI 0.79-0.86), far outperforming conventional techniques. Notably, several HHIE-S items and age were found to be significant characteristics. In contrast to traditional HHIE research, which concentrates on the psychological effects of hearing loss, this study combines cutting-edge machine learning techniques-specifically, the LGBM classifier-with the HHIE-S tool. The incorporation of SHAP values enhances the interpretability of the model's predictions and provides a more comprehensive comprehension of the significance of various aspects.

CONCLUSIONS

Our methodology highlights the great potential that arises from combining machine learning with validated hearing evaluation instruments such as the HHIE-S. Healthcare practitioners can anticipate ARHL more accurately thanks to this integration, which makes it easier to intervene quickly and precisely.

Associations Between Age-Related Hearing Loss, Cognitive Impairment, and Multiple Chronic Conditions in a Group Care Setting

PURPOSE

The purpose of this study was to explore the relationships between hearing loss, cognitive status, and a range of health outcomes over a period of 2 years in a sample of older adults who are enrolled in Program of All-Inclusive Care for the Elderly, which is a Medicare/Medicaid beneficiary program for individuals who are nursing home eligible but living in the community at time of enrollment.

METHOD

The sample (N = 144) includes a diverse (47% White/non-Hispanic, 35% Black/African American, and 16% Latin/Hispanic) group of adults ranging from 55 to 93 years old. We used medical chart data to measure respondents' cognitive and health status, including chronic conditions and hospital use. Hearing status was measured once at the beginning of the 2-year review period. We used logistic regression and negative binomial hurdle models for analyses. We used latent class analysis (LCA) to explore the extent to which respondents cluster into a set of "health profiles" characterized by their hearing, cognitive status, and health conditions.

RESULTS

We found that hearing loss is weakly associated with heart disease and diabetes and associated with cerebrovascular disease and falls; cognitive impairment is also associated with cerebrovascular disease and the number of falls. LCA indicates that respondents cluster into a variety of health profiles with a consistent pairing of hearing loss and depression.

CONCLUSIONS

The results are largely consistent with associations reported in epidemiological studies that include age-related hearing loss. Of particular interest in this study is the LCA that suggested that all of the profiles associated with a high likelihood of hearing loss included a high risk of depression. The co-occurrence of these two factors highlights the need to identify and treat hearing loss in older adults, especially as part of the treatment plan for individuals with depressive symptoms.

Dementia and Hearing Aid Use and Cessation: A National Study

PURPOSE

The current standard for management of hearing loss in the United States involves the use of a hearing aid. Anecdotal evidence suggests that the use of a hearing aid may be less effective in the context of dementia, though national data on use and cessation are not described.

METHOD

This longitudinal analysis of the National Health and Aging Trends Study followed participants who self-reported hearing aid use to estimate risk of hearing aid cessation over 9 years. We examine whether hearing aid cessation differs by dementia status using generalized estimating equations logistic regression accounting for loss to follow-up. Supplemental analyses were undertaken to examine the contribution of caregiving and environmental factors on hearing aid cessation.

RESULTS

Of 1,310 older adults who reported hearing loss (25% 80-84 years, 51% women, 74% White), 22% with dementia and 57% baseline hearing aid use. Dementia increased likelihood of ceasing hearing aid use during the first year after adoption (OR = 2.07, 95% CI [1.33, 3.23], p interaction = .11). In later years, older adults with either a previous or recent diagnosis of dementia had a 95% higher odds of hearing aid cessation (OR = 1.95, 95% CI [1.31, 2.90]), a decrease in odds with respect to the first year after adoption, when compared to participants without dementia, after adjusting for demographic, health, and economic factors. Economic and social factors that may influence care demands (more caregivers, income-to-poverty ratio, and additional insurance) increased likelihood for cessation for those with dementia.

CONCLUSIONS

Older adults with (vs. without) dementia are more likely to cease hearing aid use over time, most notably during the first year after adoption. Strategies to support hearing ability, such as self-management or care partner education, may improve communication for those living with co-occurring hearing loss and dementia.

Effect of polypharmacy and Fall-Risk-Increasing Drugs (FRIDs) on falls among Brazilian older adults: The SABE cohort study

Polypharmacy, considered as the use of multiple medications, has been one of the factors associated with a higher risk of falls among older adults. However, the association of this factor regardless of the use of Fall-Risk-Increasing Drugs (FRIDs) has not been extensively explored.

OBJECTIVES

This study aimed to evaluate the longitudinal association of polypharmacy with falls and verify whether this association is independent of FRID use.

METHODS

A longitudinal study was conducted with a representative sample of the urban population aged 60 years and over in the city of São Paulo, Brazil, from 2000 to 2006. The analysis of the association among polypharmacy, the use of FRIDs, and the occurrence of falls over the years was performed using Generalized Estimating Equation (GEE) models adjusted for covariates.

RESULTS

The association between polypharmacy and falls was significantly attenuated after the adjustment for covariates and FRIDs. Users of two or more FRIDs had higher odds of falls (OR = 1.51; CI [1.16; 1.96]).

CONCLUSION

FRID use was associated with the occurrence of falls among older adults. The number of medications must be kept to the minimum necessary, and FRIDs should be avoided in approaches to preventing falls among older adults.

Association between hearing status and social participation in Japanese older adults: A cross-sectional study from the Japan gerontological evaluation study

PURPOSE

Hearing is known to decline with age. As sensitivity to speech declines, conversation becomes more difficult and social interactions are affected, resulting in increased risk of cognitive decline. This study aimed to examine the relationship between hearing status and social participation.

MATERIALS AND METHODS

The study included 21,117 adults aged 65 years or older who responded to a survey in 2019. The survey asked participants about their hearing status and how frequently they participated in certain social activities.

RESULTS

The analysis of the relationship between degree of hearing and social activity showed lower hearing status odds ratios for those who participated more frequently in social activities compared to those who participated less frequently. The odds ratios were as follows, hobby clubs (OR 0.81, 95%CI 0.78-0.84), activities such as teaching skills or passing on experiences to others (OR 0.69, 95%CI 0.65-0.75), and meeting with friends (OR 0.77, 95%CI 0.74-0.79). Compared to those who did not participate in social activities, those who participated in three or more types of groups had significantly lower hearing impairment (OR 0.75, 95% CI 0.72-0.79).

CONCLUSION

Hearing impairment was shown to inhibit participation in activities, including those that require communication with multiple people or smooth communication, those that involve a wide range of ages, and those that involve work and movement. Hearing impairment should be identified and addressed in its early stages to prevent its negative impact on social participation.

Perceptions Surrounding Cochlear Implants Among At-Risk and Qualifying Older Adults in the United States

OBJECTIVE

Limited evidence to date has examined public perceptions of cochlear implants among adult hearing aid users with moderate to profound hearing loss. The current work was conceived with the chief objective of characterizing the perceptions surrounding cochlear implants among the prospective candidate pool.

STUDY DESIGN

National cross-sectional survey study.

SETTING

United States.

PATIENTS

Adults between 50 and 80 years of age with self-reported moderate to moderately severe (n = 200) or moderately severe to profound (n = 200) hearing loss currently using hearing aids.

RESULTS

The overall survey response rate was 12%. Median age at time of survey for the 400 respondents was 66 years (interquartile range, 60-71 yr) and included 215 (54%) men. In total, 26% did not think of hearing loss as a medical condition, and another 23% were unsure. Overall, 63% of respondents had heard of cochlear implants, but only 2% indicated they were very familiar with them. Despite 52% of respondents reporting "very positive" or "somewhat positive" feelings about cochlear implants, only 9% indicated they were "very likely" to get a cochlear implant in the future, including 7% of those with estimated moderately severe to profound hearing loss at time of survey.

CONCLUSIONS

Even among people with presumed qualifying levels of hearing loss, there exists a widespread lack of familiarity with cochlear implantation as a viable treatment option. This limited awareness seems influenced by a generally poor appreciation for hearing loss as a chronic disease state that warrants treatment. However, among those familiar with cochlear implants, they are generally viewed favorably.

Traditional Chinese medicine for the prevention and treatment of presbycusis

Background

Presbycusis/Age-related hearing loss is a sensorineural hearing loss caused by age-related deterioration of the auditory system that poses a risk to the physical and mental health of older people, including social and cognitive decline. It is also associated with frailty, falls and depression. There are currently no specific medications for the treatment of presbycusis, and early detection and intervention are key to its prevention and management. Traditional Chinese medicine interventions may offer opportunities in the prevention and treatment of presbycusis, but there is no relevant review.

Methods

Literature searches was conducted using PubMed, Cochrane Library, Web of Science, and China National Knowledge Infrastructure (CNKI) databases for review articles, research articles, clinical trials, meta-analyses, and case studies in animal models and clinical trials.

Results

We summarized the pathological mechanisms associated with presbycusis, related to genetic factors, environment, lifestyle, and molecular mechanisms related to oxidative stress, mitochondrial dysfunction, and inflammatory pathways. It is suggested that traditional Chinese medicine interventions may offer opportunities in the prevention and treatment of presbycusis using active ingredients of herbs or formulas, acupuncture, and exercise such as Tai Chi Chuan or Ba Duan Jin. The active ingredients of herbs or formulas may exert ear protection through Nrf2-mediated antioxidant pathways, NF-kB and NLRP3-related anti-inflammatory signaling, and regulation of autophagy.

Conclusions

Here, we review the pathogenetic factors and pathological mechanisms involved in presbycusis, as well as traditional Chinese medicine interventions and treatments, with the aim of providing a new perspective for the prevention and treatment of hearing loss in the elderly and further improving their quality of life.

Sensory Reweighting for Postural Control in Older Adults with Age-Related Hearing Loss

There is growing evidence linking hearing impairments and the deterioration of postural stability in older adults. To our knowledge, however, no study to date has investigated the effect of age-related hearing loss on the sensory reweighting process during postural control. In the absence of data, much is unknown about the possible mechanisms, both deleterious and compensatory, that could underly the deterioration of postural control following hearing loss in the elderly. The aim of this study was to empirically examine sensory reweighting for postural control in older adults with age-related hearing loss as compared to older adults with normal hearing. The center of pressure of all participants was recorded using a force platform and the modified clinical test of sensory interaction and balance protocol. The results suggest that individuals with age-related hearing loss displayed increased somatosensory reliance relative to normal hearing younger adults. This increased reliance on somatosensory input does not appear to be effective in mitigating the loss of postural control, probably due to the concomitant deterioration of tactile and proprioceptive sensitivity and acuity associated with aging. Beyond helping to further define the role of auditory perception in postural control, these results further the understanding of sensory-related mechanisms associated with postural instability in older adults.

The association of hearing loss with frailty among community-dwelling older adults: findings from the National Health and Aging Trends Study

BACKGROUND

The identification of modifiable risk factors is crucial for the prevention and/or reversal of frailty, which is associated with significant morbidity and mortality. Hearing loss affects two-thirds of older adults in the United States (U.S.) and is associated with physical and cognitive decline which may increase frailty risk. We investigated the association of hearing loss and hearing aid use with frailty and pre-frailty in a nationally representative sample of older adults in the U.S.

METHODS

Cross-sectional analysis of the National Health and Aging Trends Study (2021 round). The better-hearing ear pure-tone average (BPTA) at speech-frequencies (0.5-4 kHz) was modeled continuously (per 10 dB) and categorically (no ≤ 25 dB, mild 26-40 dB, moderate or greater > 40 dB hearing loss). Hearing aid use was self-reported. The physical frailty phenotype (frail, pre-frail, robust) was determined based on Fried criteria: unintentional weight loss, exhaustion, low physical activity, weakness, slow walking speed. We used multinomial multivariable regression adjusted for sociodemographic and health characteristics (odds ratios [95% Confidence Intervals]).

RESULTS

Among 2,361 participants (mean age = 81 years, 56% female, 19% Black), 860 (36%) had mild and 864 (37%) had moderate or greater hearing loss. Worse hearing was associated with greater odds of being frail versus robust (OR = 1.20 [1.05-1.38] per 10 dB difference). Categorically, moderate or greater hearing loss was associated with greater odds of being frail (OR = 1.84 [1.01-3.08]) and pre-frail (OR = 1.46 [1.01-2.10]) versus robust. Among 1,724 participants with hearing loss, compared to hearing aid users (N = 522), nonusers had greater odds of being frail (OR = 2.54 [1.54-4.18]) and pre-frail (OR = 1.51 [1.05-2.17]) versus robust, and frail versus pre-frail (OR = 1.68 [1.04-2.72]).

CONCLUSIONS

In a nationally representative sample of older adults in the U.S., using gold-standard hearing measures and a validated frailty phenotype, hearing loss and lack of hearing aid use was cross-sectionally associated with frailty and pre-frailty. Future longitudinal studies are needed to establish if hearing loss is a risk factor for frailty, which may have significant clinical importance.

Incidence and Risk Factors of Falls Among Older People in Nursing Homes: Systematic Review and Meta-Analysis

OBJECTIVES

Falls are common among older people in nursing homes, and the assessment of fall risk factors is critical for the success of fall prevention interventions. This study aimed to systematically assess the incidence and risk factors of falls in older people living in nursing homes.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

Older people living in nursing homes.

METHODS

Literature searches were conducted independently by 2 researchers in 8 databases. Qualities of included studies were assessed using the Newcastle-Ottawa Scale. The prevalence and risk factors of falls were analyzed with a random effects model. All analyses were performed by R software, x64 4.2.2.

RESULTS

In 18 prospective studies addressing older adults living in nursing homes, the pooled incidence of falls was 43% (95% CI 38%-49%), and the meta-regression analysis indicated that the incidence generally decreased from 1998 to 2021. The following risk factors had a strong association with all falls: fall history, impaired ADL performance, insomnia, and depression. Risk factors with low to moderate correlation were vertigo, walking aids, poor balance, use of antidepressants, use of benzodiazepines, use of antipsychotics, use of anxiolytics, polypharmacy, dementia, unsteady gait, hearing problems, and gender (being male). Having bed rails was identified as a protective environmental factor.

CONCLUSIONS AND IMPLICATIONS

The results from our meta-analysis suggest that the incidence of falls of older adults living in nursing homes is high, and the risk factors for falls are various. Assessments of balance and mobility, medical condition, and use of medications should be included as key elements in the fall risk assessments of older people in nursing homes. Environmental risk factors still need to be explored in future studies. Tailored fall prevention strategies should be implemented by addressing the modifiable risk factors.

Third-party disability in cochlear implant users

OBJECTIVE

To date, auditory rehabilitation mainly focuses on the person with hearing impairment (PHI). This study aimed to analyse the burden of hearing loss on significant others (SOs), and to explore the impact of contextual and mediating psychosocial co-factors and auditory rehabilitation by cochlear implantation (CI).

DESIGN AND STUDY SAMPLE

Third-party disability (SOS-HEAR) and quality of life (Nijmegen Cochlear Implant Questionnaire) were evaluated in 41 PHI scheduled for CI surgery and their close partners pre- and 6-month post-implantation. Further, age, hearing status, educational level, depressive symptoms (GDS-15), coping strategies (Brief-COPE), resilience (RS-13), stress (PSQ) of SOs and PHI were studied.

RESULTS

Hearing loss imposes a burden on SOs, particularly in relation to changes in communication and socialisation. Third-party disability was higher in SOs of PHI with lower educational background (p = 0.04) and of advanced age (p = 0.008). Hearing status of SOs negatively correlated with SOS-HEAR (p = 0.04). After CI, quality of life of PHI and third-party disability of SOs improved (p < 0.001), except in relationship changes. SOs with higher pre-operative burden also experienced more third-party disability afterwards (p ≤ 0.003).

CONCLUSION

Audiological rehabilitation should expand to include SOs in the rehabilitation process, as the burden experienced by SOs might persist even after CI.

Assessment of prognostic biomarkers in sudden sensorineural hearing loss: A systematic review and meta-analysis

Sudden sensorineural hearing loss (SSNHL) is defined as hearing loss of more than 30 dB in less than 72 h. SSNHL is a frequent complaint and an emergency in otolaryngology. Various biomarkers have been used to determine the prognosis of SSNHL. This systematic review and meta-analysis aims to evaluate the relationship between the different biomarkers and the prognosis of SSNHL. We searched English-language literature up to October 2022 in four databases, including PubMed, Google Scholar, Cochrane, and Science Direct. This search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. This study was reported in the International Prospective Register of Systematic Reviews (PROSPERO) database (ID = CRD42022369538). All studies examining the role of neutrophil to lymphocyte ratio (NLR) concluded that higher NLR is associated with a worse prognosis. The results of studies regarding the relationship between platelet to lymphocyte ratio (PLR) and tumor necrosis factor (TNF) are controversial. Other factors shown to be associated with SSNHL include Glycated hemoglobin (HbA1C), blood glucose, iron levels, serum endocan, salusin-beta, and bone turnover biomarkers. This meta-analysis showed that PLR, NLR, and neutrophils were significantly different between recovered and non-recovered patients. PLR, NLR, and neutrophil count are reliable tools to assess the prognosis of patients with SSNHL.

Effect of auditory deprivation on adaptive locomotion: Interaction with lower visual field occlusion

Auditory stimuli have been suggested to play a role in adequately controlling movement; however, their influence is not fully understood, particularly regarding dynamic behaviors, such as adaptive locomotion. This study aimed to investigate whether auditory deprivation affects adaptive locomotion. In particular, we aimed to elucidate the role of the auditory sense in obstacle avoidance by manipulating the visual field, which provides crucial sensory information for movement control. Sixteen participants approached a 15-cm obstacle located 6 m away and stepped over it under four different conditions that combined two factors: the hearing condition controlled by wearing earmuffs with and without holes, and the lower visual field condition controlled by carrying opaque white and transparent boards. Spatiotemporal variables during the approach to the obstacle were measured using an electronic walkway, whereas foot clearance over the obstacle was assessed using a motion-capture system. Participants who experienced auditory deprivation and lower visual field occlusion demonstrated greater variability in step length when approaching the obstacle compared with the other conditions. The leading and trailing foot clearances were higher under lower visual field occlusion conditions. Furthermore, when participants were under conditions of auditory deprivation, greater variability was observed in the clearance of the leading foot. These results suggest that auditory information contributes to movement stabilization during adaptive locomotion. Our findings provide evidence that auditory and visual senses complement each other during motor actions, indicating that adaptive locomotion can be influenced by the integration of multiple sensory inputs.

Patient-Reported Outcome Measures for Hearing Aid Benefit and Satisfaction: Content Validity and Readability

PURPOSE

Numerous patient-reported outcome measures (PROMs) are available to measure hearing aid benefit and satisfaction. It is unclear to what extent currently available PROMs on hearing aid outcomes, often developed decades ago, meet current guidelines for good content validity and readability. This study evaluated the content validity and readability of PROMs that focus on perceived hearing aid benefit and/or satisfaction.

METHOD

A literature review was conducted to identify eligible instruments. Content validity evaluation included mapping extracted questionnaire items to the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework. In addition, study design in content validity methodology was evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments study design checklist for PROM instruments. Readability was estimated using the Simple Measure of Gobbledygook measure.

RESULTS

Thirteen questionnaires were identified and evaluated. Item content focused primarily on the components of environmental factors as well as activity limitations and participation restrictions with less emphasis on body functions and personal factors. The content validity methodology analysis revealed an underuse or lack of reporting of a qualitative methodology in assessing patient and professional perspectives. All the included questionnaires exceeded the recommended sixth-grade reading level.

CONCLUSIONS

The categories covered by hearing aid PROMs vary considerably, with no single instrument comprehensively covering all the key ICF components. Future development of hearing aid outcome measures should consider a mixed methodology approach for improved content validity and ensure an appropriate reading level.

Hearing and sociality: the implications of hearing loss on social life

Hearing is essential to the formation of social relationships and is the principal afferent of social life. Yet hearing loss, which is one of the most prevalent forms of sensory disability worldwide and is critical for social development, has received little attention from the social interventionalist perspective. The purpose of this mini-review is to describe the basic neurobiological principles of hearing and to explore the reciprocal relationships between social support, hearing loss, and its psychosocial comorbidities. We also discuss the role of social enrichment in sensorineural recovery and identify open questions within the fields of hearing physiology and social networks.

Screening for hearing loss using the electronic whisper test: A prospective cross-sectional study

Background

Hearing screening is a method for early identification of hearing loss. Hearing screening is widely used in hospitals as part of physical examination. However, some of them are difficult to operate outside the hospitals regarding portability and user-friendliness. Therefore, we developed a simple yet easy-to-use portable electronic whisper test (EWT) for field deployment, particularly on many subjects. The EWT validity is a hearing screening method compared to pure-tone audiometry.

Methods

This study was a cross-sectional comparative with a prospective approach. The subjects were outpatients at the Audiology Clinic of Dr. Soetomo Academic Medical Center, Surabaya, Indonesia, who met the inclusion and exclusion criteria. Statistical analysis made sensitivity and specificity tables using a 2 × 2 table, positive and negative predictive values.

Results

Samples of 50 participants (100 ears) obtained a sensitivity value of 83%, specificity of 78%, positive predictive value of 45%, and negative predictive value of 95%.

Conclusions

The EWT is valid for use as a hearing screening method.

Consistent hearing aid use is associated with lower fall prevalence and risk in older adults with hearing loss

BACKGROUND

Falls and their sequelae cost more than $50 billion every year. Older adults with hearing loss are at 2.4 times greater risk of falls than their normal hearing peers. Current research is inconclusive about whether hearing aids can offset this increased fall risk, and no previous studies considered if outcomes differed based on the consistency of hearing aid use.

METHODS

Individuals 60 years and older with bilateral hearing loss completed a survey consisting of the Fall Risk Questionnaire (FRQ) and questions about hearing loss history, hearing aid use, and other common fall risk factors. In this cross-sectional study, fall prevalence, as well as fall risk (based on FRQ score), was compared between hearing aid users and non-users. A separate group of consistent hearing-aid users (at least 4 h daily use for more than 1 year) was also compared with inconsistent/non-users.

RESULTS

Responses from 299 surveys were analyzed. Bivariate analysis found 50% reduced odds of experiencing a fall for hearing aid users compared with non-users (OR = 0.50 [95% CI: 0.29-0.85], p = 0.01). After adjusting for age, sex, hearing loss severity, and medication usage, those who reported any hearing aid use still had lower odds of falls (OR = 0.48 [95% CI: 0.26-0.90], p = 0.02) and lower odds of being at risk for falls (OR = 0.36 [95% CI: 0.19-0.66] p < 0.001) than non-users. Results for consistent hearing aid users demonstrate an even stronger association of lowered odds of falling (OR = 0.35 [95% CI: 0.19-0.67], p < 0.001) and lower odds of being at risk for falls (OR = 0.32 [95% CI: 0.12-0.59], p < 0.001), suggesting a potential dose-response relationship.

CONCLUSIONS

These findings suggest that use of hearing aids-especially consistent hearing aid use-is associated with lower odds of experiencing a fall or being classified as at risk for falls in older individuals with hearing loss.

Longitudinal Auditory Benefit for Elderly Patients After Cochlear Implant for Bilateral Hearing Loss, Including Those Meeting Expanded Centers for Medicare & Medicaid Services Criteria

OBJECTIVE

To examine the effect of patient age on longitudinal speech understanding outcomes after cochlear implantation (CI) in bilateral hearing loss.

STUDY DESIGN

Retrospective cohort study.

SETTING

Tertiary academic center.

PATIENTS

One thousand one hundred five adult patients with bilateral hearing loss receiving a unilateral CI between 1987 and 2022InterventionsNone.

MAIN OUTCOME MEASURES

Postoperative speech recognition outcomes, including AzBio sentences, consonant-nucleus-consonant word, and Hearing in Noise Test in quiet were analyzed at short-term (<2 yr), medium-term (2-8 y), and long-term (>8 yr) term postoperative intervals.

RESULTS

Eighty-six very elderly (>80 yr), 409 elderly (65-80 yr), and 709 nonelderly (18-65 yr) patients were included. Short-term postoperative AzBio scores demonstrated similar magnitude of improvement relative to preoperative scores in the very elderly (47.6, 95% confidence interval [CI], 28.9-66.4), elderly (49.0; 95% CI, 39.2-58.8), and nonelderly (47.9; 95% CI, 35.4-60.4). Scores for those older than 80 years remained stable after 2 years after implant, but in those 80 years or younger, scores continued to improve for up to 8 years (elderly: 6.2 [95% CI, 1.5-12.4]; nonelderly: 9.9 [95% CI, 2.1-17.7]) after implantation. Similar patterns were observed for consonant-nucleus-consonant word scores. Across all age cohorts, patients with preoperative Hearing in Noise Test scores between 40 and 60% had similar scores to those with preoperative scores of less than 40%, at short-term (82.4, 78.9; 95% CI, -23.1 to 10.0), medium-term (77.2, 83.9; 95% CI, -15.4 to 8.2), or long-term (73.4, 71.2; 95% CI, -18.2 to 12.2) follow-up.

CONCLUSIONS

Patients older than 80 years gain significant and sustained auditory benefit after CI, including those meeting expanded Centers for Medicare & Medicaid Service criteria for implantation. Patients younger than 80 years demonstrated continued improvement over longer periods than older patients, suggesting a role of central plasticity in mediating CI outcomes as a function of age.

Falls, fear of falling, and related factors in patients with diabetic foot disease

BACKGROUND

Falls and fear of falling (FOF) are common in patients with diabetic foot disease (DFD).

PURPOSE

To understand the relationship between falls, FOF, and related factors in patients with DFD.

METHOD

We recruited 70 patients being treated for DFD at two hospitals in Korea. A structured questionnaire was used in investigating fall experience, FOF, and related factors.

RESULTS

Among the participants, 42.8 % fell in the past year, and FOF was reported in 57.1 %. Rates of "no caregiver," "DFD duration (>1 year)," and "burning pain" were higher in fallers than non-fallers. The rates of "older adults (≥65 years of age)," "unemployed," "not using assistive devices," "visual impairment," and "hearing impairment" were higher in patients with FOF than in those without FOF. However, the level of balance confidence was lower in patients with FOF.

CONCLUSIONS

The fall experience of patients with DFD was associated with the presence of their caregiver, disease-related factors, and foot pain symptoms, while FOF was related to age and fall-related factors.

Are Current Data Sufficient to Infer that Hearing Aids Contribute to Postural Control and Balance in Older Adults? A Systematic Review

INTRODUCTION

Balance and postural control are related to hearing and hearing loss, but whether they can be improved with hearing aid use in older adults is not clear. We systematically reviewed controlled studies in which balance and hearing were tested in experienced older hearing aid users to determine the potential effects of hearing aid use on balance.

METHODS

The review was pre-registered in PROSPERO and performed in accordance with PRISMA. The question, inclusion, and exclusion criteria were defined using the Population, Intervention, Control, Outcomes and Study design (PICOS) framework. Older adults with hearing loss and no experience with hearing aids, or balance tests conducted without hearing aids in hearing aid users served as controls.

RESULTS

A total of 803 studies were screened, eight of which met the inclusion and exclusion criteria and were included in the final review. Five of the eight studies found a significant correlation between the use of hearing aids and the outcomes of the balance tests. The quality of the studies was limited or moderate. Key Discussion: The role of hearing aids in balance and postural control is unclear because of the quality of the papers and the sparse reporting of hearing status and hearing aids quality of fitting and use.

Screening for Falls: A Prospective Pilot Study for the Audiology Clinic

PURPOSE

The purpose of this study was to determine if clinical measures that audiologists may already be using or are able to collect on a routine basis are useful in screening for future falls.

METHOD

This prospective cohort study protocol included 20 community-dwelling participants aged 60 years or older who completed case history questions, pure-tone and speech audiometry, common questionnaires, the Timed Up and Go test, and a prospective 6-month falls diary to determine which measures were correlated with the number of prospective 6-month falls.

RESULTS

Five participants (25%) fell in the 6 months after the research session. Significant correlations were noted between prospective falls and age, home safety modifications, engagement in fall prevention activities, and history of falls in the last 12 months.

CONCLUSION

Straightforward case history questions that could be part of a routine audiologic evaluation, such as fall history in the previous year, are significantly correlated with prospective number of falls in 6 months. These questions could help to identify audiology patients who may benefit from further fall risk assessment.

Association of Hearing Status and Cognition With Fall Among the Oldest-Old Chinese: A Nationally Representative Cohort Study

OBJECTIVES

The oldest-old (aged ≥80 years) are the most rapidly growing population and age is related to hearing impairment (HI) and cognitive decline. We aimed to estimate the association between HI and fall, and the effect of different cognitive states on this association among the oldest-old Chinese population.

DESIGN

A total of 6931 Chinese oldest-old were included in the 2018 cross-cohort from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). The presence of HI was identified by using a dichotomized metric of self-reported hearing status. Cognitive function was evaluated by using the modified Mini-Mental State Examination (MMSE). Cognitive impairment was defined as the MMSE score below 24 points. Data on fall history were collected by questionnaires survey from the participants or their relatives. We studied the association of hearing status and cognitive function with fall by using multivariable logistic regressions, upon adjustment of sociodemographic characteristics, lifestyles, and health conditions.

RESULTS

Our participants were aged 92 (range 80 to 117) on average, with 60.1% being women. In total, 39.1% of the participants had reported HI, 50.1% had cognitive impairment, and 26.2% had a history of falling. Participants with HI had a higher incidence of cognitive impairment (79.4%), as compared with their counterparts without HI (31.3%). Compared with those without HI, HI patients had a higher risk of falling after full adjustment for potential confounders (OR = 1.16 [95% confidence interval, CI, 1.01, 1.32], p = 0.031). In comparison with HI participants without cognitive impairment, HI patients with cognitive impairment had a higher fall risk (OR = 1.45 [95% CI = 1.23, 1.72], p < 0.001).

CONCLUSIONS

Association of hearing status and cognition with fall was, for the first time, examined on the basis of a nationally-representative oldest-old Chinese population. Poor cognitive performance was common in individuals with HI, and those with HI and cognitive impairment further increased the risk of falling.

Hearing Loss: Insights for Home Care Clinicians

Hearing loss is a common problem caused by aging, noise exposure, ototoxic medications, and illness. Given their frequent contact with older adults, home care clinicians are uniquely positioned to recognize the adverse effects of hearing loss on physical, social, and cognitive health. This article explores the factors that contribute to hearing loss, highlighting their cumulative effects on overall hearing ability. The consequences of untreated hearing loss support the urgency of early identification, prompt intervention, and proper management of hearing disability. This article also provides an overview of available treatment options, including traditional prescription hearing aids and recently approved over-the-counter devices. By incorporating components of awareness, treatment, and effective communication strategies, healthcare clinicians can take an integrated approach to improve the overall well-being and quality of life of individuals struggling with hearing loss.

Cochlear implantation impact on health service utilisation and social outcomes: a systematic review

BACKGROUND

Hearing loss can have a negative impact on individuals' health and engagement with social activities. Integrated approaches that tackle barriers and social outcomes could mitigate some of these effects for cochlear implants (CI) users. This review aims to synthesise the evidence of the impact of a CI on adults' health service utilisation and social outcomes.

METHODS

Five databases (MEDLINE, Scopus, ERIC, CINAHL and PsychINFO) were searched from 1st January 2000 to 16 January 2023 and May 2023. Articles that reported on health service utilisation or social outcomes post-CI in adults aged ≥ 18 years were included. Health service utilisation includes hospital admissions, emergency department (ED) presentations, general practitioner (GP) visits, CI revision surgery and pharmaceutical use. Social outcomes include education, autonomy, social participation, training, disability, social housing, social welfare benefits, occupation, employment, income level, anxiety, depression, quality of life (QoL), communication and cognition. Searched articles were screened in two stages ̶̶̶ by going through the title and abstract then full text. Information extracted from the included studies was narratively synthesised.

RESULTS

There were 44 studies included in this review, with 20 (45.5%) cohort studies, 18 (40.9%) cross-sectional and six (13.6%) qualitative studies. Nine studies (20.5%) reported on health service utilisation and 35 (79.5%) on social outcomes. Five out of nine studies showed benefits of CI in improving adults' health service utilisation including reduced use of prescription medication, reduced number of surgical and audiological visits. Most of the studies 27 (77.1%) revealed improvements for at least one social outcome, such as work or employment 18 (85.7%), social participation 14 (93.3%), autonomy 8 (88.9%), education (all nine studies), perceived hearing disability (five out of six studies) and income (all three studies) post-CI. None of the included studies had a low risk of bias.

CONCLUSIONS

This review identified beneficial impacts of CI in improving adults' health service utilisation and social outcomes. Improvement in hearing enhanced social interactions and working lives. There is a need for large scale, well-designed epidemiological studies examining health and social outcomes post-CI.

New horizons in hearing conditions

Hearing conditions such as hearing loss, tinnitus and hyperacusis are highly prevalent in the population and can severely impact communication and quality of life. Hearing is affected by multiple factors, including heredity, noise exposure, age, sex, ear disorders and lifestyle factors. Globally, hearing loss affects over 80% of adults aged 80 years and older, is often experienced in combination with other long-term health conditions and is a mid-life risk factor for dementia. To form a themed collection, we searched Age and Ageing for articles on hearing conditions published from 2000 onwards. This resulted in 22 articles included within the collection. They examined a range of important topics related to hearing healthcare and research, including noise-induced hearing loss, health service quality and safety, psychological and psychosocial consequences of hearing loss and co-morbidities of hearing loss. All articles reported on hearing loss; there were no published articles with a primary focus on other hearing conditions such as tinnitus or hyperacusis, on the health of older people from the Deaf community or on users of Cochlear implants, suggesting key gaps in knowledge and targets for future research. This New Horizons article highlights novel directions in research and practice and takes a forward look at how research into hearing conditions may develop in years to come. It highlights opportunities for the growth of patient-centred research and hearing healthcare supported by the better integration of health and care services as well as cross-speciality working to include common co-morbid health conditions.

Cardiocerebrovascular risk in sensorineural hearing loss: results from the National Health and Nutrition Examination Survey 2015 to 2018

Objective

This study aims to determine whether the risks of cardiocerebrovascular disease are relevant to sensorineural hearing loss (SNHL) based on a national database.

Methods

A total of 1,321 participants aged from 18 to 69 with complete data including medical history and audiometry from the NHANES database (2015-2018) were analyzed. All included participants had available hearing data and the average thresholds of the hearing data were measured and calculated as low-frequency pure-tone average (LFPTA; 500, 1,000, and 2,000 Hz) and high-frequency pure-tone average (HFPTA; 3,000, 4,000, 6,000, and 8,000 kHz). SNHL was defined as an average pure tone of more than or equal to 20 dB in at least one better ear. Multivariable models to assess the association between cardiocerebrovascular risks and SNHL were used in this study.

Results

The prevalence of stroke was 1.6% in individuals with SNHL and 0.4% in individuals without SNHL (p = 0.023). A higher cardiovascular risk score was observed in SNHL patients compared to participants without SNHL (1.58 vs. 0.90, p < 0.001). Stroke was associated with a 3.67-fold increase in the risk of SNHL (95% CI: 1.12-12.00, p = 0.032) in univariable logistic regression, and the association (OR = 4.22, 95%CI = 1.28-13.93, p = 0.020) remained significant after adjusting for several covariates. Multivariable logistic regression models indicated a positive correlation between cardiovascular risk and SNHL (OR = 1.66, 95% CI = 1.40-1.96, p < 0.001), but no significant relationship was shown with all covariates adjusted. However, significant associations were found between SNHL and both age and sex in both univariable and multivariable logistic regression models.

Conclusion

Our findings suggested that a higher cardiocerebrovascular risk burden was associated with an increased risk of SNHL, and the relationship may be influenced by age and sex. Future longitudinal studies are needed to investigate the mechanistic and pathologic vascular hypothesis of SNHL.

Differing postural control patterns in individuals with bilateral and unilateral hearing loss

OBJECTIVES

Hearing loss (HL) is associated with imbalance and increased fall risk. The mechanism underlying this relationship and differences across types of hearing loss remains unclear. Head mounted displays (HMD) can shed light on postural control mechanisms via an analysis of head sway.

PURPOSE

The purpose of this study was to evaluate head sway in response to sensory perturbations in individuals with bilateral (BHL) or unilateral hearing loss (UHL) and compare them to controls.

MATERIALS AND METHODS

We recruited 36 controls, 23 individuals with UHL and 14 with BHL. An HMD (HTC Vive) measured head sway while participants stood on the floor, hips-width apart. Stimuli included two levels of visuals and sound. Root Mean Square Velocity (RMSV) and Power Spectral Density (PSD) were used to quantify head sway.

RESULTS

Adjusting for age, individuals with BHL had significantly higher anterior-posterior and medio-lateral RMSV than controls and individuals with UHL. Individuals with UHL demonstrated significantly lower response to visual perturbations in RMSV AP and in all 3 frequency segments of PSD compared to controls. Individuals with UHL showed significantly lower movements at high frequencies compared to controls. Sounds or severity of HL did not impact head sway.

CONCLUSIONS

Individuals with BHL demonstrated increased sway with visual perturbations and should be clinically assessed for balance performance and fall risk. Individuals with UHL exhibited reduced responses to visual stimuli compared with controls, which may reflect conscious movement processing. Additional studies are needed to further understand the mechanistic relationship between hearing loss and imbalance.

Associations between hearing loss and clinical outcomes: population-based cohort study

Background

Hearing loss (HL) is a leading cause of disability worldwide, but its clinical consequences and population burden have been incompletely studied.

Methods

We did a retrospective population-based cohort study of 4,724,646 adults residing in Alberta between April 1, 2004 and March 31, 2019, of whom 152,766 (3.2%) had HL identified using administrative health data. We used administrative data to identify comorbidity and clinical outcomes, including death, myocardial infarction, stroke/transient ischemic attack, depression, dementia, placement in long-term care (LTC), hospitalization, emergency visits, pressure ulcers, adverse drug events and falls. We used Weibull survival models (binary outcomes) and negative binomial models (rate outcomes) to compare the likelihood of outcomes in those with vs without HL. We calculated population-attributable fractions to estimate the number of binary outcomes associated with HL.

Findings

The age-sex-standardized prevalence of all 31 comorbidities at baseline was higher among participants with HL than those without. Over median follow-up of 14.4 y and after adjustment for potential confounders at baseline, participants with HL had higher rates of days in hospital (rate ratio 1.65, 95% CI 1.39, 1.97), falls (RR 1.72, 95% CI 1.59, 1.86), adverse drug events (RR 1.40, 95% CI 1.35, 1.45), and emergency visits (RR 1.21, 95% CI 1.14, 1.28) compared to those without, and higher adjusted hazards of death, myocardial infarction, stroke/transient ischemic attack, depression, heart failure, dementia, pressure ulcers and LTC placement. The estimated number of people with HL who required new LTC placement annually in Canada was 15,631, of which 1023 were attributable to HL. Corresponding estimates for new dementia among people with HL were 14,959 and 4350, and for stroke/TIA the estimates were 11,582 and 2242.

Interpretation

HL is common, is often accompanied by substantial comorbidity, and is associated with significant increases in risk for a broad range of adverse clinical outcomes, some of which are potentially preventable. This high population health burden suggests that increased and coordinated investment is needed to improve the care of people with HL.

Association Between Hearing Handicap and Life-Space Mobility in a Patient Population

PURPOSE

The purpose of this study was to evaluate the association between self-reported hearing handicap and life-space mobility utilizing the Life-Space Questionnaire (LSQ). Life-space mobility reflects how an individual moves through their daily physical and social environment, and the role of hearing loss in life-space mobility is not fully understood. We hypothesized that those with higher self-reported hearing handicap would be more likely to demonstrate restricted life-space mobility.

METHOD

A total of 189 older adults (M age = 75.76 years, SD = 5.81) completed a mail-in survey packet including the LSQ and Hearing Handicap Inventory for the Elderly (HHIE). Participants were categorized into one of three groups ("no/none," "mild/moderate," or "severe" hearing handicap) according to HHIE total score. LSQ responses were dichotomized to either "nonrestricted/typical" or "restricted" life-space mobility groups. Logistic regression models were performed to analyze life-space mobility differences among the groups.

RESULTS

Logistic regression results demonstrated no statistically significant association between hearing handicap and LSQ.

CONCLUSIONS

The results of this study indicate that there is no association between self-reported hearing handicap and life-space mobility as evaluated using a mail-in version of the LSQ. This counters other studies that have demonstrated that life space is associated with chronic illness, cognitive functioning, and social and health integration.
