Association of Sensory and Cognitive Impairment With Healthcare Utilization and Cost in Older Adults

A Consolidated Understanding of the Contribution of Redox Dysregulation in the Development of Hearing Impairment

The etiology of hearing impairment is multifactorial, with contributions from both genetic and environmental factors. Although genetic studies have yielded valuable insights into the development and function of the auditory system, the contribution of gene products and their interaction with alternate environmental factors for the maintenance and development of auditory function requires further elaboration. In this review, we provide an overview of the current knowledge on the role of redox dysregulation as the converging factor between genetic and environmental factor-dependent development of hearing loss, with a focus on understanding the interaction of oxidative stress with the physical components of the peripheral auditory system in auditory disfunction. The potential involvement of molecular factors linked to auditory function in driving redox imbalance is an important promoter of the development of hearing loss over time.

The association between dual sensory loss and healthcare expenditure: Mediating effect of depression

BACKGROUND

Previous studies have suggested the dual sensory loss (DSL) is linked to depression, and that they are associated with higher healthcare expenditures, respectively. However, the association between DSL, depression and healthcare expenditures remains ambiguous.

OBJECTIVES

The current study aims to examine the association between DSL, depression and healthcare expenditures as well as catastrophic health expenditures (CHE) among Chinese people aged 45 and above.

METHODS

We first utilized the China Health and Retirement Longitudinal Survey (CHARLS) 2018 to obtain data from a total of 13,412 Chinese individuals aged 45 and above to conduct a cross-sectional study. DSL was defined as a combined variable of self-reported vision loss and hearing loss. Depression was measured using The Center for Epidemiologic Studies Depression Scale (CESD-10). The healthcare expenditures, including outpatient out-of-pocket cost and inpatient out-of-pocket cost, were obtained from the Harmonized CHARLS section. CHE were defined as out-of-pocket (OOP) health spending equal to or higher than 40 % of a household's capacity to pay. A Tobit linear regression with three models and a path analysis were conducted to estimate the association between DSL, depression and healthcare expenditures and CHE. Then we utilized 2011CHARLS and 2018CHARLS to present a longitudinal analysis. A path analysis was conducted to estimate the association between 2011DSL, 2018depression and 2018healthcare expenditures and CHE.

RESULTS

Depression has a significant mediating effect between DSL and healthcare expenditures. (For outpatient OOP cost: a = 0.453, b = 23.559, c = 25.257, the proportion of mediating effect in total effect = 29.71 %; for inpatient OOP cost: a = 0.453, b = 13.606, c = 15.463, the proportion of mediating effect in total effect = 28.50 %; all P < 0.05). The mediating effect of depression also exists in the association between DSL and CHE (a = 0.453, b = 0.018, c = 0.043, the proportion of mediating effect in total effect = 15.90 %; P < 0.05). The mediation effect of depression on healthcare expenditures and CHE also exists in the longitudinal analysis using CHARLS 2011 and CHARLS 2018 (all P < 0.05).

LIMITATIONS

The DSL status were based on self-report and we used 2018CHARLS to conduct the study, which may cause some bias.

CONCLUSION

Significant mediating effect of depression exists between DSL and higher healthcare expenditures and CHE. The mental health of elder people with DSL should be focused on, and we should have an overall viewpoint on the topic of healthcare expenditures and CHE.

Interventions to improve social network in older people with sensory impairment: a systematic review

BACKGROUND

Sensory impairment significantly reduces speech discrimination and perception ability, presenting a challenge to effective communication. It can lead to social withdrawal and a reduced social network which can lead to cognitive impairment, seriously affecting the quality of life of older people. However, it is unclear which intervention components are effective to improving social network in older people with sensory impairment.

OBJECTIVE

The aim of this systematic review was to summarize interventions designed to improve social network in older people with sensory impairment.

METHODS

We searched seven databases from inception to December 1, 2023. Eligible studies included randomized clinical trials (RCT) and quasi-experimental studies of interventions for older people with sensory impairment aimed at improving social networks. Two reviewers searched databases, extracted data, and assessed the quality of the included studies independently.

RESULTS

Nine studies including five RCTs and four quasi-experimental studies were selected, enrolling 721 older people with sensory impairment. Methodological quality of the studies was modest. Eight studies demonstrated a positive impact of the interventions used in older people with sensory impairment. The detailed effective intervention components may include communication strategies, resources for older people and their significant others, exercise or tech-back of communication, sensory device fitting, and use and maintenance of sensory devices.

CONCLUSION

There are few interventions available for improving social network in older people with sensory impairment. Most interventions mainly focus on communication education and care, and sensory device fitting and education. To improve the social network in older people with sensory impairment, it is necessary to develop more effective, multidisciplinary collaborative effective interventions and conduct more high-quality original studies.

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.

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.

An intervention to decrease sedentary behavior in older adults: A secondary analysis of a randomized controlled trial

Background

Sedentary behaviors are associated with adverse health outcomes in older adults. The feasibility of behavioral interventions in this population is unclear.

Methods

In the Sit Less, Interact, Move More (SLIMM) trial of 106 participants who had obesity, those randomized to the SLIMM intervention (N = 54) were instructed to replace sedentary activities with stepping. An accelerometer was used to measure physical activity. In this secondary analysis, mixed effect models were used to examine the effects of the SLIMM intervention on sedentary and stepping durations and steps/day by age (<70 and ≥ 70 years).

Results

Mean ages in the <70 years (N = 47) and ≥70 years (N = 59) groups were 58 ± 11 and 78 ± 5. In the older subgroup, compared to standard-of-care (N = 29), the SLIMM intervention (N = 30) significantly increased stepping duration (13, 95%CI 1-24 min/d, p = 0.038) and steps per day (1330, 95% CI 322-2338, p = 0.01) and non-significantly decreased sedentary duration by (28,95% CI -61-5 min/d, p = 0.09). In the age <70 subgroup, there was no separation between the standard of care (N = 23) and SLIMM (N = 24) groups.

Discussion

In older adults who had obesity, SLIMM intervention significantly increased stepping duration and steps per day. Interventions targeting sedentary behaviors by promoting low intensity physical activity may be feasible in this population.

Impact of functional disability on health-care use and medical costs among cancer survivors

BACKGROUND

Cancer survivors with a disability are among the most vulnerable in health status and financial hardship, but no prior research has systematically examined how disability modifies health-care use and costs. This study examined the association between functional disability among cancer survivors and their health-care utilization and medical costs.

METHODS

We generated nationally representative estimates using the 2015-2019 Medical Expenditure Panel Survey. Outcomes included use of 6 service types (inpatient, outpatient, office-based physician, office-based nonphysician, emergency department, and prescription) and medical costs of aggregate services and by each of 6 service types. The primary independent variable was a categorical variable for the total number of functional disabilities. We employed multivariable generalized linear models and 2-part models, adjusting for sociodemographics and health conditions and accounting for survey design.

RESULTS

Among cancer survivors (n = 9359; weighted n = 21 046 285), 38.8% reported at least 1 disability. Compared with individuals without a disability, cancer survivors with 4 or more disabilities experienced longer hospital stays (adjusted average marginal effect = 1.14 days, 95% confidence interval [CI] = 0.55 to 1.73), more visits to an office-based physician (average marginal effect = 1.43 visits, 95% CI = 0.51 to 2.35), and a greater number of prescriptions (average marginal effect = 12.1 prescriptions, 95% CI = 9.27 to 15.0). Their total (average marginal effect = $9537, 95% CI = $5713 to $13 361) and out-of-pocket (average marginal effect = $639, 95% CI = $79 to $1199) medical costs for aggregate services were statistically significantly higher. By type, disability in independent living was most strongly associated with greater costs for aggregate services.

CONCLUSIONS

Cancer survivors with a disability experienced greater health-care use and higher costs. Cancer survivorship planning for health care and financial stability should consider the patients' disability profile.

Vision difficulty and dementia: economic hardships among older adults and their caregivers

Introduction

Limited research has examined the economic impact of vision difficulty (VD) and dementia on older adults and their caregivers. We aimed to determine whether older adults with VD and/or dementia, and their caregivers, face more economic hardships than their counterparts without VD or dementia.

Methods

We used cross-sectional data from the 2015 National Health and Aging Trends Study (NHATS), a population-based survey of Medicare beneficiaries, linked to their family/unpaid caregivers from the National Study of Caregiving (NSOC). Regression models characterized the association of VD (self-report), dementia (survey and cognitive assessments), and co-occurring VD and dementia with debt, receiving financial help from relatives, government-based Supplemental Nutrition Assistance Program (SNAP), other food assistance, utility assistance, and caregiver financial difficulty.

Results

The NHATS sample included 6,879 community-dwelling older adults (5670 no VD/dementia, 494 VD-alone, 512 dementia-alone, 203 co-occurring VD and dementia). Adults with VD and dementia had higher odds of receiving SNAP benefits (OR = 2.6, 95%CI = 1.4-4.8) and other food assistance (OR = 4.1, 95%CI = 1.8-9.1) than adults without VD/dementia, while no differences were noted for debt, financial help, and utility assistance. Adults with VD-alone had higher odds of debt (OR = 2.1, 95%CI = 1.3-3.2), receiving financial help (OR = 1.7, 95%CI = 1.1-2.5) and other food assistance (OR = 2.7, 95%CI = 1.7-4.3); while adults with dementia-alone had higher odds of debt (OR = 2.8, 95%CI = 1.4-5.5). The NSOC sample included 1,759 caregivers (995 caring for adults without VD/dementia, 223 for VD-alone, 368 for dementia-alone, and 173 for co-occurring VD and dementia). Compared to caregivers of older adults without VD/dementia, caregivers of adults with VD and dementia had higher odds of financial difficulty (OR = 3.0, 95%CI = 1.7-5.3) while caregivers of adults with VD-alone or dementia-alone did not.

Discussion

While older adults with VD- or dementia-alone experienced increased economic hardships, disparities in food assistance were amplified among older adults with co-occurring disease. Caregivers of adults with co-occurring disease experienced more financial difficulty than caregivers of adults with a single or no disease. This study highlights the need for interventions across clinical and social services to support the economic wellbeing of our aging population and their caregivers.

Potentially Preventable Hospitalization Among Adults with Hearing, Vision, and Dual Sensory Loss: A Case and Control Study

Objective

To evaluate the risk of potentially preventable hospitalizations (PPHs) among adults with sensory loss. We hypothesized a greater PPH risk among people with a sensory loss (hearing, vision, and dual) compared with controls.

Patients and Methods

Using 2007-2016 Medicare fee-for-service claims, this retrospective, case-control study examined the risk of PPH among adults aged 65 years and older with hearing, vision, and dual sensory loss compared with their corresponding counterparts without sensory loss (between June 1, 2022, and February 1, 2023). We ran 3 step-in regression models for the 3 case and control cohorts examining PPH risk. Our generalized linear regression models controlled for age, sex, race, Elixhauser comorbidity count, rurality, neighborhood characteristics, and the number of primary care physicians and hospitals at the county level.

Results

People with vision (adjusted odds ratio [aOR], 1.21; 95% CI, 0.84-0.87) and dual sensory loss (aOR, 1.26; 95% CI, 1.14-1.40) showed a higher PPH risks than their corresponding controls. For people with hearing loss, our unadjusted models showed a higher PPH risk (OR, 1.40; 95% CI, 1.38-1.43) but after adjustment, hearing loss showed a protective association against PPH risk (OR, 0.85; 95% CI, 0.84-0.87). Moreover, in all models, annual wellness visits reduced the PPH risk by about half (eg, aOR, 0.54; 95% CI, 0.52-0.55), whereas living in disadvantaged neighborhood increased the PPH risk (eg, aOR, 1.13; 95% CI, 1.10-1.15) for cases and controls.

Conclusion

People with vision and dual sensory loss were at greater PPH risk. This study has important health policy implications in reducing PPH and is indicative of a need for more incentivized and systematic approaches to facilitating the use of preventive care, particularly among older adults living in a disadvantaged neighborhood.

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.

Health-related quality of life associated with sensory impairment in Chinese middle-aged and older adults: a cohort study

BACKGROUND

The impact of sensory impairment (SI) on individual multidimensional health has not been adequately explored in developing countries. This study examined the association of hearing or/and visual impairment with health-related quality of life (HRQoL) in the Chinese middle-aged and older population, and further explored potential discrepancies in associations by gender and rural-urban residence.

METHODS

This cohort study used four-wave data during 2011-2018 from the China Health and Retirement Longitudinal Study, and enrolled 13 342 community-dwelling adults aged 45 years or older. We employed linear mixed effects models to estimate the longitudinal associations between SI and HRQoL, and conducted interaction tests to assess gender or rural-urban differences in above associations.

RESULTS

Hearing impairment (HI) and visual impairment (VI) were separately and jointly associated with deteriorated overall HRQoL and decreased physical/mental component of HRQoL (all β<0, all p<0.05), and in particular, dual sensory impairment (DSI) exhibited greater impacts on HRQoL than either HI or VI alone. The impacts of SI on HRQoL were more evident among women or rural population than their counterparts (all p for interaction<0.05).

CONCLUSION

This study observed decreased HRQoL in association with SI. The greater impact of DSI underlines the need for integrated care for comorbid sensory conditions. Our findings also indicate the necessity to reduce the burden of SI among more vulnerable populations such as females and rural adults.

Prevalence of visual impairment in older people living with dementia and its impact: a scoping review

BACKGROUND AND OBJECTIVES

Visual impairment (VI) and dementia both increase with age, and it is likely that many older people are living with both conditions. This scoping review aims to investigate the prevalence and types of VI among older people living with dementia, and the impact of VI on older people living with dementia and their caregivers.

METHODS

This scoping review used Arksey and O'Malley's methodological framework. Studies in any setting involving people living with dementia and some assessment of either VI, eye diseases causing VI or the impact of VI were included.

RESULTS

Thirty-six studies were included. Thirty-one studies reported the prevalence of VI in older people living with dementia, while ten studies reported on impacts of VI on people living with dementia. Only one study reported on impacts on caregivers. The prevalence of VI or specific eye diseases among older people living with dementia ranged from 0.2 to 74%. The impacts of VI on older people living with dementia included increased use of hospital services, increased disability and dependency, reduced social engagement, negative emotions, increased abnormal behaviours, loss of hobbies, difficulty in using visual aids or memory aids, and greater Neuropsychiatric Inventory symptoms. And the impacts on caregivers included increased conflict and physical exhaustion.

CONCLUSION

VI is common in older people living with dementia and is associated with negative impacts on those with dementia and their caregivers. However, heterogeneity between studies in terms of setting and method for assessing and defining VI make it difficult to compare findings among studies. Further research is needed, particularly assessing the impact on caregivers.

Continuum of Care for Older Adults With Concurrent Hearing and Vision Impairment: A Systematic Review

Background and Objectives

A global report estimates up to 2% of the world population experience concurrent hearing and vision impairment (dual sensory impairment [DSI]). Older adults with DSI are often frequent users of health care, yet the evidence is limited to inform care delivery for this population. This systematic review aimed to synthesize evidence on tools and strategies for screening, assessment, and interventions that promote a continuum of care for older adults with DSI.

Research Design and Methods

The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews. Electronic databases (CINAHL, Embase, MEDLINE, PsycINFO, Cochrane Library, Global Health, and Web of Science) and clinical trial registries (ISRCTN Registry, WHO ICTRP, and ClinicalTrials.gov) were searched. The quality appraisal was performed using the Mixed Methods Appraisal Tool.

Results

Of 4,775 identified references, 28 records were selected. The review identified 7 tools and 7 strategies for DSI-specific screening, assessments, and/or interventions. Some of the most promising tools were the interRAI Community Health Assessment with deafblind supplement, adapted Montreal Cognitive Assessment, and the Severe Dual Sensory Loss screening tool. Useful strategies included the use of alternative forms of communication, assistive devices or technology, education and training for service providers, and training of older adults on the use and maintenance of assistive aids/technology. However, quality appraisal indicated a need for more robust evidence to inform clinical practice.

Discussion and Implications

Reviewed evidence pinpointed the need for training for health care providers on DSI-specific challenges and supports and the use of integrated multidisciplinary care for older adults. Future studies need to explore the development and evaluation of tools and interventions to improve the continuum of care for this group.

Factors affecting hospital services overutilization and reductive strategies in Iran: a qualitative study to explore experts' views

OBJECTIVES

This study aimed to investigate the viewpoints of the main stakeholders of the Iranian healthcare system about the overutilization of hospital services and strategies to eliminate or reduce it in Iran.

METHODS

This is a qualitative study and thematic data analysis using face-to-face semi-structured interviews and Focus Group Discussions (FGDs). We conducted eight interviewers and two FGDs with hospital stakeholders including faculty members, insurance organizations' authorities, experienced hospital administrative staff, hospital managers, and health-care providers.

RESULTS

The factors leading to the overutilization of hospital services were categorized into four main themes including site of service, quality, supplier push, and demand pull. Strategies for eliminating or reducing the overutilization of hospital services are also identified based on the influential factors.

CONCLUSION

Addressing overutilization of hospital services in the health system and adherence to policies for reducing or eliminating overutilization is a way to make preventive strategies to overcome overutilization. Developing a national plan to integrate utilization management into health system programs is a strategy to combat overutilization in various levels of the health system including hospital setting.

Association between the domestic use of solid cooking fuel and increased prevalence of depression and cognitive impairment in a big developing country: A large-scale population-based study

Background

Previous studies have suggested that air pollution affects physiological and psychological health. Using solid fuel at home is a significant source of indoor air pollution. The associations between solid fuel use and depressive symptoms and cognitive health were unclear among older adults from low- and middle-income countries (LMICs).

Methods

To evaluate the association of solid fuel use with depressive symptoms and cognitive health among older adults, we obtained data from the Longitudinal Aging Study in India (LASI) and excluded subjects younger than 60 years and without critical data (solid fuel use, depressive symptoms, and cognitive health). The 10-item Center for Epidemiologic Studies Depression Scale (CES-D-10) was used to assess depressive symptoms, with more than ten indicative of depression. Cognitive health was assessed using measures from the Health and Retirement Study (HRS), and subjects with the lowest 10th percentile were considered to have cognitive impairment. The participants' responses defined solid fuel use. Multivariable logistic regression, linear regression, subgroup analysis, and interaction tests were performed to appraise the relationship between solid fuel use and depression and cognitive impairment.

Results

A total of 29,789 participants over 60 years old were involved in this study. Almost half of the participants (47.5%) reported using solid fuel for home cooking. Compared with clean fuel use, solid fuel use was related to an increased prevalence of depression [odds ratio (OR) 1.09, 95% CI 1.03-1.16] and higher CES-D-10 scores (β 0.23, 95% CI 0.12-0.35) after fully adjusted covariables. Using solid fuel was also related to a higher risk of cognitive impairment (OR 1.21, 95% CI 1.11-1.32) and a lower cognitive score (β -0.63, 95% CI -0.79 to -0.47) compared with those who used clean fuel. In the subgroup analysis, the prevalence of depression increased in females and non-smokers. The association of solid fuel use with depression and cognitive impairment exists in subgroups of BMI, economic status, caste, living area, education, and drinking.

Conclusions

The use of solid fuel at home was associated with an increased prevalence of depression and cognitive impairment among older adults in India.

Pathways to reduced overnight hospitalizations in older adults: Evaluating 62 physical, behavioral, and psychosocial factors

As our society ages and healthcare costs escalate, researchers and policymakers urgently seek potentially modifiable predictors of reduced healthcare utilization. We aimed to determine whether changes in 62 candidate predictors were associated with reduced frequency, and duration, of overnight hospitalizations. We used data from 11,374 participants in the Health and Retirement Study—a national sample of adults aged >50 in the United States. Using generalized linear regression models with a lagged exposure-wide approach, we evaluated if changes in 62 predictors over four years (between t0;2006/2008 and t1;2010/2012) were associated with subsequent hospitalizations during the two years prior to t2 (2012–2014 (Cohort A) or 2014–2016 (Cohort B)). After robust covariate-adjustment, we observed that changes in some health behaviors (e.g., those engaging in frequent physical activity had 0.80 the rate of overnight hospital stays (95% CI [0.74, 0.87])), physical health conditions (e.g., those with cancer had 1.57 the rate of overnight hospital stays (95% CI [1.35, 1.82])), and psychosocial factors (e.g., those who helped friends/neighbors/relatives 100–199 hours/year had 0.73 the rate of overnight hospital stays (95% CI [0.63, 0.85])) were associated with subsequent hospitalizations. Findings for both the frequency, and duration, of hospitalizations were mostly similar. Changes in a number of diverse factors were associated with decreased frequency, and duration, of overnight hospitalizations. Notably, some psychosocial factors (e.g., informal helping) had effect sizes equivalent to or larger than some physical health conditions (e.g., diabetes) and health behaviors (e.g., smoking). These psychosocial factors are mostly modifiable and with further research could be novel intervention targets for reducing hospitalizations.

International depiction of the cost of functional independence limitations among older adults living in the community: a systematic review and cost-of-impairment study

BACKGROUND

Functional independence limitations restrict older adult self-sufficiency and can reduce quality of life. This systematic review and cost of impairment study examined the costs of functional independence limitations among community dwelling older adults to society, the health care system, and the person.

METHODS

Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines this systematic review included community dwelling older adults aged 60 years and older with functional independence limitations. Databases (Cochrane Database of Systematic Reviews, EconLit, NHS EED, Embase, CINAHL, AgeLine, and MEDLINE) were searched between 1990 and June 2020. Two reviewers extracted information on study characteristics and cost outcomes including mean annual costs of functional independence limitations per person for each cost perspective (2020 US prices). Quality was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist.

RESULTS

85 studies were included. The mean annual total costs per person (2020 US prices) were: $27,380.74 (95% CI: [$4075.53, $50,685.96]) for societal, $24,195.52 (95% CI: [$9679.77, $38,711.27]) for health care system, and $7455.49 (95% CI: [$2271.45, $12,639.53]) for personal. Individuals with cognitive markers of functional independence limitations accounts for the largest mean costs per person across all perspectives. Variations across studies included: cost perspective, measures quantifying functional independence limitations, cost items reported, and time horizon.

CONCLUSIONS

This study sheds light on the importance of targeting cognitive markers of functional independence limitations as they accounted for the greatest costs across all economic perspectives.

Association between dual sensory impairment and risk of mortality: a cohort study from the UK Biobank

BACKGROUND

Dual sensory impairment is affecting over 10% of older adults worldwide. However, the long-term effect of dual sensory impairment (DSI) on the risk of mortality remains controversial. We aim to investigate the impact of single or/and dual sensory impairment on the risk of mortality in a large population-based sample of the adult in the UK with 14-years of follow-up.

METHODS

This population-based prospective cohort study included participants aged 40 and over with complete records of visual and hearing functions from the UK Biobank study. Measurements of visual and hearing functions were performed at baseline examinations between 2006 and 2010, and data on mortality was obtained by 2021. Dual sensory impairment was defined as concurrent visual and hearing impairments. Cox proportional hazards regression models were employed to evaluate the impact of sensory impairment (dual sensory impairment, single visual or hearing impairment) on the hazard of mortality.

RESULTS

Of the 113,563 participants included in this study, the mean age (standard deviation) was 56.8 (8.09) years, and 61,849 (54.5%) were female. At baseline measurements, there were 733 (0.65%) participants with dual sensory impairment, 2,973 (2.62%) participants with single visual impairment, and 13,560 (11.94%) with single hearing impairment. After a follow-up period of 14 years (mean duration of 11 years), 5,992 (5.28%) participants died from all causes. Compared with no sensory impairment, dual sensory impairment was significantly associated with an estimated 44% higher hazard of mortality (hazard ratio: 1.44 [95% confidence interval, 1.11-1.88], p = 0.007) after multiple adjustments.

CONCLUSIONS

Individuals with dual sensory impairment were found to have an independently 44% higher hazard of mortality than those with neither sensory impairment. Timely intervention of sensory impairment and early prevention of its underlying causes should help to reduce the associated risk of mortality.

Longitudinal relationship between sensory impairments and depressive symptoms in older adults: The mediating role of functional limitation

BACKGROUND

The underlying mechanism between sensory impairments (SIs) and depressive symptoms among Chinese older adults is not well understood. This study aims to explore the mediating role of functional limitation on the longitudinal relationship between SIs and depressive symptoms among older adults in China.

METHODS

A total of 4130 older adults who participated in the 3-year follow-up China Health and Retirement Longitudinal Study (CHARLS) were included in the analysis. The hierarchical multiple linear regression model and nonparametric bootstrapping method were employed to explore the relationship between SIs and depressive symptoms, and the mediating role of functional limitation in this link.

RESULTS

The prevalence of self-reported hearing impairment (HI) only, vision impairment (VI) only, and dual sensory impairment (DSI) at baseline were 5.7%, 22.2%, and 58.6%, respectively. After adjusting for controlling variables, older adults with DSI had significantly higher levels of depressive symptoms compared with those without SIs at baseline (β = .07, p = .005). The magnitude of mediation effect from DSI to depressive symptoms via functional limitation was a*b = 0.060 (BCa 95% confidence interval: 0.031-0.094).

CONCLUSIONS

Functional limitation partially mediated the relationship between DSI and depressive symptoms among Chinese older adults. Interventions of DSI and functional limitation should be included in depressive symptoms prevention among older adults in China.

Impact of financial barriers on health status, healthcare utilisation and economic burden among individuals with cognitive impairment: a national cross-sectional survey

OBJECTIVE

To study the impact of financial barriers to healthcare on health status, healthcare utilisation and costs among patients with cognitive impairment.

DESIGN

Cross-sectional.

SETTING

National Health Interview Survey (NHIS), 2011-2017.

PARTICIPANTS

Patients with cognitive impairment aged 18 years or older.

INTERVENTIONS

Financial barriers to healthcare were identified using a series of NHIS prompts asking about the affordability of healthcare services.

PRIMARY OUTCOME MEASURES

Health status was based on a survey prompt about respondents' general health. Healthcare utilisation included office visits, home healthcare visits, hospital stays and emergency department (ED) visits. Economic burden was based on the family spending on medical care. Logistic regression models were used to examine the impact of financial barriers to healthcare access on health status, home healthcare visits, office visits, hospital stays and ED visits, respectively.

RESULTS

Compared with cognitively impaired respondents without financial barriers to healthcare access, those with financial barriers were more likely to be unhealthy (OR 0.64, 95% CI 0.57 to 0.72). Cognitively impaired respondents with financial barriers were less likely to have home healthcare (OR 0.69, 95% CI 0.48 to 0.99) and more likely to have hospital stays (OR 1.33, 95% CI 1.19 to 1.48) and ED visits (OR 1.50, 95% CI 1.35 to 1.67). In addition, compared with cognitively impaired respondents without financial barriers to healthcare access, those with the barriers were more likely to have an increased economic burden (OR=1.85, 95% CI 1.65 to 2.07).

CONCLUSION

Financial barriers to healthcare worsened health status and increased use of ED, hospitalisation and economic burden. Policy decision-makers, providers and individuals with cognitive impairment should be aware of the impact of financial barriers and take corresponding actions to reduce the impact.

Associations of sensory impairment and cognitive function in middle-aged and older Chinese population: The China Health and Retirement Longitudinal Study

Background

Little is known about the associations between vision impairment, hearing impairment, and cognitive function. The aim of this study was to examine whether vision and hearing impairment were associated with a high risk for cognitive impairment in middle-aged and older Chinese adults.

Methods

A total of 13 914 Chinese adults from the China Health and Retirement Longitudinal Study (CHARLS) baseline were selected for analysis. Sensory impairment was assessed from a single self-report question, and we categorized sensory impairment into four groups: no sensory impairment, vision impairment, hearing impairment, and dual sensory impairment. Cognitive assessment covered memory, mental state, and cognition, and the data was obtained through a questionnaire.

Results

Memory was negatively associated with hearing impairment (β = -0.043, 95% confidence interval (CI) = -0.076, -0.043) and dual sensory impairment (β = -0.033, 95% CI = -0.049, -0.017); mental status was negatively associated with vision impairment (β = -0.034, 95% CI = -0.049, -0.018), hearing impairment (β = -0.070, 95% CI = -0.086, -0.055), and dual sensory impairment (β = -0.054, 95% CI = -0.070, -0.039); and cognition was negatively associated with vision impairment (β = -0.028, 95% CI = -0.044, -0.013), hearing impairment (β = -0.074, 95% CI = -0.090, -0.059), and dual sensory impairment (β = -0.052, 95% CI = -0.067, -0.036), even after adjusting for demographics, social economic factors, and lifestyle behavior.

Conclusions

Vision and hearing impairment are negatively associated with memory, mental status, and cognition for middle-aged and elderly Chinese adults. There were stronger negative associations between sensory impairment and cognitive-related indicators in the elderly compared to the middle-aged.

Evaluating the Association Between Hearing Loss and Falls in Adults With Vestibular Dysfunction or Nonvestibular Dizziness

OBJECTIVES

Although emerging evidence suggests that hearing loss (HL) is an independent risk factor for falls, it is unclear how HL may impact falls risk in adults with vestibular dysfunction and nonvestibular dizziness. The purpose of this study was to characterize the impact of HL on falls in patients with vestibular dysfunction and nonvestibular dizziness relative to a group of patients without dizziness. In addition, this study aimed to evaluate whether there was an interactive effect between HL and vestibular dysfunction or nonvestibular dizziness on the odds of falling.

DESIGN

The authors conducted a retrospective cross-sectional study of 2,750 adult patients with dizziness evaluated at a tertiary care center vestibular clinic between June 1, 2015, and October 7, 2020. Only patients with available self-reported falls status, as extracted from the electronic medical record, were included. Patients were classified into the following diagnostic groups based on rotary chair testing and videonystagmography: benign paroxysmal positional vertigo (BPPV, n = 255), unilateral vestibular hypofunction (UVH, n = 456), bilateral vestibular hypofunction (BVH, n = 38), central dysfunction (n = 208), multiple diagnoses (n = 109), and dizzy, nonvestibular (n = 1,389). A control group of patients without dizziness (n = 295) was identified by a random sample of audiology patients. Degree of HL was characterized by the 4-frequency pure tone average (PTA) (0.5, 1, 2, and 4 kHz) of the better hearing ear. Demographic variables, comorbidities, cognitive impairment status, and falls-associated medications were extracted from the electronic medical record and included as covariates during analysis. Potential associations between PTA and falls status and possible interactions between diagnostic group and PTA were explored using multivariate logistic regression.

RESULTS

The BVH and central dysfunction groups had the highest rates of self-reported falls at 26.3% and 26.9%, respectively. The control group had the lowest rate of self-reported falls at 6.4%. With the exception of the multiple diagnoses group, all diagnostic groups had elevated odds of falling compared with the control group, when adjusting for demographics, comorbidities, cognitive impairment status, and falls-associated medications. There was no significant association between degree of HL and falls status (odds ratio [OR] = 1.02; 95% confidence interval [CI] = 0.93, 1.11; p = 0.713) when adjusting for diagnostic group and all other covariates. Furthermore, there were no significant interactions between diagnostic group and degree of HL on the odds of falling.

CONCLUSIONS

These results indicate that HL was not associated with falls in patients with vestibular dysfunction or nonvestibular dizziness, while adjusting for demographics, comorbidities, and falls-associated medications. There was no significant interactive effect observed between HL and vestibular dysfunction or nonvestibular dizziness on the odds of falling. As previously reported, vestibular dysfunction and nonvestibular dizziness were independently associated with falls relative to a group of patients without dizziness. A population-based study utilizing more robust falls data is needed to explore a potential association between HL and falls in those with vestibular dysfunction.

The Nexus of Sensory Loss, Cognitive Impairment, and Functional Decline in Older Adults: A Scoping Review

BACKGROUND AND OBJECTIVES

The prevalence of cognitive impairment and sensory loss in hearing or vision increases with age. Based on the Information Processing Model, cognitive impairment coupled with sensory loss may exacerbate disability in late life. Yet this issue has not been systematically studied. The purpose of this scoping review was to examine the literature that studied the relationship between cognitive impairment, sensory loss, and activities of daily living in older adults.

RESEARCH DESIGN AND METHODS

Two reviewers independently screened 1,410 studies identified from five electronic databases (Medline, EMBASE, PsycINFO, CINHAL, and the Web of Science). The search was completed in June 2020. A study was eligible if it included measurements of cognitive function, vision or hearing, and activities of daily living. Additionally, the data analyses must address how cognitive impairment and sensory loss are related to the performance of activities of daily living.

RESULTS

The final review included 15 studies. Findings show an additive effect of cognitive impairment and sensory loss on the activities of daily living. Cognitive impairment or vision loss independently relates to the decline in activities of daily living. Hearing loss relates to the decline only when the loss is severe, or if the daily task is hearing specific.

DISCUSSION AND IMPLICATIONS

Older adults with coexisting sensory loss and cognitive impairment have the highest risk or prevalence of disability, comparing to cognitive impairment or sensory loss alone. This finding highlights the importance of developing interventions to reduce the risk of disability for older adults experiencing multiple impairments.

Near Vision but not Hearing Loss is Associated with Lacking a Usual Source of Health Care

Objectives: Sensory loss may be a barrier to accessing healthcare services, and this study seeks to examine the association of sensory loss with whether older adults report having a usual source of health care. Methods: Our study included 7548 older adults who participated in the National Health and Aging Trends Study in 2015. Having a self-reported usual source of health care was our outcome, and hearing and vision loss were our primary independent variables. Results: In multivariate analysis accounting for demographics, socioeconomic, health status, and environmental covariates, near vision loss but not distance vision or hearing loss was associated with decreased odds of having a usual source of health care. Discussion: That older adults with near vision loss were less likely to report having a usual source of health care is concerning. Examining barriers to care is needed to identify sensory loss-relevant processes to optimize and intervene upon.

The role of self-reported hearing status in the risk of hospitalisation among Chinese middle-aged and older adults

OBJECTIVE

To determine the association between self-reported hearing status and risk of hospitalisation among Chinese middle-aged and older adults.

DESIGN

Prospective cohort study. Discrete-time hazards models and negative binomial models were fitted to examine the relationship.

STUDY SAMPLE

About 11,902 participants aged 45 years or older with no hospitalisation at baseline.

RESULTS

49.28-62.70% of the participants reported their hearing as fair or poor. For older adults aged 60 and above, compared to people with excellent and very good hearing, those with good, fair or poor hearing reported shorter time to first hospitalisation [hazard ratio (HR) = 1.38, 1.38, 1.63, respectively]. They also manifested greater number of hospitalisations [incident rate ratio (IRR) = 1.21, 1.25, 1.54, respectively], and longer duration of hospitalisation (IRR = 1.36, 1.26, 1.53, respectively). However, there was no significant association between hearing status and hospitalisation for middle-aged adults for none of the hearing categories.

CONCLUSIONS

Although no significant relationship between hearing and hospitalisation was found for middle-aged adults, older adults with poorer hearing experienced greater risk of hospitalisation. Given that hearing impairment is highly prevalent among older adults, future analyses are needed to investigate whether hearing rehabilitative therapies could help mitigate hospitalisations in hearing-impaired older adults.

Hearing Screening for Residents in Long-Term Care Homes Who Live with Dementia: A Scoping Review

BACKGROUND

Hearing loss is highly prevalent in older adults, particularly among those living with dementia and residing in long-term care homes (LTCHs). Sensory declines can have deleterious effects on functioning and contribute to frailty, but the hearing needs of residents are often unrecognized or unaddressed.

OBJECTIVE

To identify valid and reliable screening measures that are effective for the identification of hearing loss and are suitable for use by nursing staff providing care to residents with dementia in LTCHs.

METHODS

Electronic databases (Embase, Medline, PsycINFO, CENTRAL, and CINAHL) were searched using comprehensive search strategies, and a stepwise approach based on Arksey & O'Malley's scoping review and appraisal process was followed.

RESULTS

There were 193 scientific papers included in the review. Pure-tone audiometry was the most frequently reported measure to test hearing in older adults living with dementia. However, measures including self- or other-reports and questionnaires, review of medical records, otoscopy, and the whisper test were found to be most suitable for use by nurses working with older adults living with dementia in LTCHs.

CONCLUSION

Although frequently used, the suitability of pure-tone audiometry for use by nursing staff in LTCHs is limited, as standardized audiometry presents challenges for many residents, and specific training is needed to successfully adapt test administration procedures and interpret results. The whisper test was considered to be more suitable for use by staff in LTCH; however, it yields a limited characterization of hearing loss. There remains an urgent need to develop new approaches to screen hearing in LTCHs.

Assessment of Sensory Impairment and Health Care Satisfaction Among Medicare Beneficiaries

IMPORTANCE

Satisfaction with care is associated with improved quality of care and health outcomes. Sensory impairment can be a barrier to effective communication and access to care, and this may result in reduced satisfaction with care.

OBJECTIVE

This study examined the association between sensory impairment and health care satisfaction among Medicare beneficiaries.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used data from the 2017 Medicare Current Beneficiary Survey (MCBS), a nationally representative in-person survey of Medicare beneficiaries. Functional sensory impairment was categorized as no sensory impairment, hearing impairment, vision impairment, and dual sensory impairment. Patient dissatisfaction included responses on quality of care, ease to get to a doctor, out-of-pocket costs paid, information given, and doctors' concern with overall health rather than an isolated symptom or disease.

EXPOSURES

Self-reported functional sensory impairment.

MAIN OUTCOMES AND MEASURES

Multivariable-adjusted odds ratios (ORs) of the association between dissatisfaction with care and sensory impairment.

RESULTS

A total of 10 783 respondents representing 44 736 889 Medicare beneficiaries (8944 [85.3%] aged ≥65 years, 5733 [52.9%] women, and 8195 [75.5%] non-Hispanic White) were included. Dual sensory impairment compared with no sensory impairment was associated with the highest odds of dissatisfaction across outcomes, including quality of care (OR, 1.52; 95% CI, 1.12-2.08). Compared with no sensory impairment, having dual sensory impairment (OR, 1.82; 95% CI, 1.40-2.37), hearing impairment (OR, 1.67; 95% CI, 1.29-2.17), or vision impairment (OR, 1.56; 95% CI, 1.18-2.08) were associated with dissatisfaction with the information provided about what was wrong. Those with hearing impairment (OR, 1.38; 95% CI, 1.03-1.86) or dual sensory impairment (OR, 2.03; 95% CI, 1.55-2.66) were more likely to be dissatisfied with doctors' concern with overall health compared with those with no sensory impairment. Having dual sensory impairment or vision impairment only was associated with greater odds of dissatisfaction with ease to get to a doctor (dual sensory: OR, 1.69; 95% CI, 1.24-2.30; vision: OR, 1.63; 95% CI, 1.14-2.31) and out-of-pocket costs paid (dual sensory: OR, 1.27; 95% CI, 1.04-1.54; vision: OR, 1.31; 95% CI, 1.07-1.61).

CONCLUSIONS AND RELEVANCE

These findings contribute to the growing body of literature on sensory impairment and patient satisfaction and have implications for health care system planning and spending to provide patient-centered care for older adults.

Differences in Comorbid Conditions Among Older Adult Participants in Cardiac Rehabilitation

PURPOSE

Most older adults eligible for cardiac rehabilitation (CR) do not participate or participate with low frequency, although it is a standard of care for patients with cardiovascular disease (CVD). Identifying the barriers to older adult participation is key in improving CR efficacy.

METHODS

A range of patient characteristics was analyzed in relation to on-site frequency of participation in a CR program by older adult patients. These characteristics included demographics and indications for referral, as well as CVD and non-CVD diagnoses. The prevalence of these characteristics was compared among three patient cohorts, ranging from high contact frequency to minimal contact frequency of on-site participation in CR.

RESULTS

Among the three participation frequency cohorts, no differences were noted in demographic factors, indications for referral, or CVD diagnoses. However, patients with hearing impairment (OR = 4.15: 95% CI, 1.32-13.08) or visual impairment (OR = 4.11: 95% CI, 1.46-11.59) at time of enrollment were more likely to be found in the minimal contact cohorts than the moderate or high contact frequency cohorts.

CONCLUSIONS

Whereas differences in CVD had little bearing on frequency of CR participation in older patients, differences in hearing and visual impairment varied significantly. Patients with hearing and vision impairments attended less frequently. Sensory impairment has previously been demonstrated to impact health care utilization by older adults, but is rarely considered in the treatment of CVD or CR. As sensory impairments are extremely prevalent among geriatric patients, further study of these potential barriers to care might open possibilities for older adult participation in CR.

Age-related hearing loss and provider-patient communication across primary and secondary care settings: a cross-sectional study

BACKGROUND

The prevalence of age-related hearing loss (ARHL) increases with age. Older adults are amongst the most dependent users of healthcare and most vulnerable to medical error. This study examined health professionals' strategies, as well as level of formal training completed, for communication with older adults with ARHL, and their views on the contribution of ARHL to suboptimal quality of patient care.

METHODS

A 17-item questionnaire was distributed to a sample of Irish primary care physicians, as well as hospital-based clinicians providing inpatient palliative care and geriatric services.

RESULTS

A total of 172 primary care physicians and 100 secondary care providers completed the questionnaire. A total of 154 (90%) primary and 97 (97%) secondary care providers agreed that ARHL had a negative impact on quality of care. Across both settings, 10% of respondents reported that communication issues contributed to multiple medication error events each year. Although only 3.5% of secondary care providers and 13% of primary care physicians attended formal training on communication with hearing-impaired patients, 66.5% of respondents were confident in their capacity to communicate with these patients. Primary care physicians reported that they either never used assistive hearing technology (44%) or were unfamiliar with this technology (49%).

CONCLUSIONS

Primary and secondary care health providers reported that ARHL reduces patient care quality and may initiate errors leading to patient harm. Formal training addressing the communication needs of ARHL patients appears to be underdeveloped, and there is a limited familiarity with assistive hearing technology. This is both an error in health professional training and healthcare services.

Dual sensory impairment and psychosocial factors. Findings based on a nationally representative sample

BACKGROUND

A considerable proportion of individuals in late life experience dual sensory impairment (DSI), which can be defined as the combined presence of hearing and visual problems. However, there is little knowledge regarding the psychosocial correlates of DSI. Consequently, our objective of this study was to identify the link between DSI and psychosocial factors in middle-aged and older adults.

METHODS

Data were used from the sixth wave of the nationally representative German Ageing Survey. Individuals were classified as dual sensory impaired when both visual and hearing impairments existed. As psychosocial correlates, we included life satisfaction, positive affect, negative affect, depressive symptoms, loneliness, social isolation, self-esteem and autonomy. Outcome measures were quantified using widely established scales. In our analytical sample, there were 5138 observations.

RESULTS

Bivariate analysis showed that, compared to individuals with no sensory impairment, individuals with DSI had markedly worse psychosocial factors (in terms of life satisfaction, positive affect, negative affect, depressive symptoms, loneliness, social isolation, self-esteem and autonomy). Adjusting for various covariates, regression analysis showed that individuals with DSI consistently experienced worse psychosocial factors compared to individuals with no sensory impairment.

CONCLUSION

Our current study stressed the cross-sectional association between DSI and worse psychosocial factors. Longitudinal studies are needed to confirm our findings.
