Order of Onset of Physical Frailty and Cognitive Impairment and Risk of Repeated Falls in Community-Dwelling Older Adults.

OBJECTIVES: To examine whether physical frailty onset before, after, or in concert with cognitive impairment is differentially associated with fall incidence in community-dwelling older adults. DESIGN: A longitudinal observational study. SETTING AND PARTICIPANTS: Data from 1337 older adults age ≥65 years and free of physical frailty or cognitive impairment at baseline were obtained from the National Health Aging Trends Study (2011‒2017), a nationally representative cohort study of US older adult Medicare beneficiaries. METHODS: Participants were assessed annually for frailty (physical frailty phenotype) and cognitive impairment (bottom quintile of clock drawing test or immediate and delayed recall; or proxy-report of diagnosis of dementia or AD8 score of ≥2). Incident falls were ascertained annually via self-report. Multinomial logistic regression was performed to estimate the association between order of first onset of cognitive impairment and/or frailty and incident single or repeated falls in the 1-year interval following their first onset. RESULTS: Of the 1,337, 832 developed cognitive impairment first (termed "CI first"), 286 developed frailty first (termed "frailty first") and 219 had co-occurrence of cognitive impairment and frailty within one year (termed "CI-frailty co-occurrence") over 5 years. Overall, 491 (34.5%) had at least 1 fall during the 1-year interval following the onset of physical frailty and/or cognitive impairment. After adjustment, "CI-frailty co-occurrence" was associated with a more than 2-fold increased risk of repeated falls than "CI first" (odds ratio 2.35, 95% confidence interval 1.51‒3.67; P < .001). No significant difference was found between participants with "frailty first" and "CI first" (P = .07). In addition, the order of onset was not associated with risk of a single fall. CONCLUSIONS AND IMPLICATIONS: Older adults experiencing "CI-frailty co-occurrence" had the greatest risk of repeated falls compared with those with "CI first" and "frailty first". Fall risk screening should consider the order and timing of onset of physical frailty and cognitive impairment.

Self-reported dual sensory impairment, dementia, and functional limitations in Medicare beneficiaries.

BACKGROUND: Vision and hearing impairments often co-exist with dementia, and all are independently associated with limitations in daily activities. Our aim was to examine the association of dual sensory impairment with functional limitations, and further examine the combined estimated association of sensory impairment and dementia with these functional limitations. METHODS: Cross-sectional analysis of the National Health and Aging Trends Study (NHATS), a population-based cohort of Medicare beneficiaries, was performed. Participants were selected from the 2015 round. Survey weighted Poisson regression models adjusted for dementia, demographics, and health status variables examined the association of self-reported dual sensory impairment (no sensory impairment, single sensory impairment, dual sensory impairment) with scores of limitations in mobility, self-care, and household activities. Models were repeated to take into account the combined effects of dual sensory impairment and dementia. RESULTS: Overall, 7124 participants representative of Medicare beneficiaries 65 years or older were included. Of them, 43.9% were 75 years or older and 55.3% were female. Older adults with dual sensory impairment had greater limitations with mobility (prevalence rate ratio [PRR] = 1.45, 95% CI = 1.28-1.63), self-care (PRR = 1.41, 95% CI = 1.25-1.59), and household activities (PRR = 1.54, 95% CI = 1.37-1.72) compared with those without sensory impairment. They also had greater limitations than those with a single sensory impairment across the different activity categories. In models taking into account the combined estimated effect of both sensory impairment and dementia, those with dual sensory impairment and dementia had greater limitations than those without sensory impairment or dementia in each category (mobility: PRR = 1.85, 95% CI = 1.59-2.14, self-care: PRR = 1.86, 95% CI = 1.59-2.18, household: PRR = 2.41, 95% CI = 2.09-2.77). CONCLUSIONS: Older adults with dual sensory impairment had greater functional limitations compared with those without sensory impairment and those with a single sensory impairment. Strategies to improve visual and/or hearing function (e.g., sensory aids, rehabilitation) could potentially help prevent or minimize disability, even among those with dementia.

Prevalence of Concurrent Functional Vision and Hearing Impairment and Association With Dementia in Community-Dwelling Medicare Beneficiaries.

Importance: Impairments in vision or hearing are common and have been independently linked to higher risk of dementia in older adults. There is a limited understanding of the prevalence of concurrent functional vision and hearing impairment (dual sensory impairment) and its contribution to dementia risk. Objective: To examine the age-specific prevalence of functional dual sensory impairment among older adults, and to investigate the cross-sectional and 7-year longitudinal associations between functional dual sensory impairment and dementia. Design, Setting, and Participants: This cohort study of 7562 older adults used data from the US National Health and Aging Trends Study (NHATS), a nationally representative cohort study of community-dwelling, Medicare beneficiaries aged 65 years and older in the US. Participants in the study with complete data on hearing, vision, and dementia were included in analysis. Data were collected between 2011 and 2018, and between March 2018 and May 2020. Exposures: Self-reported functional sensory impairments (ie, no sensory impairment, functional vision impairment only, functional hearing impairment only, and functional dual sensory impairment). Main Outcomes and Measures: Age-specific prevalence of functional sensory impairments was calculated. Generalized linear regression with a complementary log-log link and a discrete time proportional hazards model with a complementary log-log link were used to assess the cross-sectional and 7-year longitudinal hazard of dementia. Results: Of 7562 participants, 3073 (40.7%) were ages 80 years or older and 4411 (58.3%) were women. Overall, 5.4% (95% CI, 4.7%-6.1%) of participants reported functional vision impairment only, 18.9% (95% CI, 18.9%-17.8%) reported functional hearing impairment only, and 3.1% (95% CI, 2.7%-3.5%) reported functional dual sensory impairment (prevalence estimates are weighted). Participants reporting sensory impairments were older (no impairment: age ≥90 years, 2.12% [95% CI, 1.79%-2.46%] vs functional dual sensory impairment: age ≥90 years, 20.06% [95% CI, 16.02%-24.10%]), had lower education (no impairment:

Do Caregiving Factors Affect Hospitalization Risk Among Disabled Older Adults?

BACKGROUND/OBJECTIVES: Hospitalization is common among older adults with disability, many of whom receive help from a caregiver and have dementia. Our objective was to evaluate the association between caregiver factors and risk of hospitalization and whether associations differ by dementia status. DESIGN: Longitudinal observational study. SETTING: The 1999 and 2004 National Long-Term Care Survey and the 2011 and 2015 National Health and Aging Trends Study, linked caregiver surveys, and Medicare claims. PARTICIPANTS: A total of 2,589 community-living Medicare fee-for-service beneficiaries, aged 65 years or older (mean age = 79 years; 63% women; 31% with dementia), with self-care or mobility disability and their primary family or unpaid caregiver. MEASUREMENTS: Self-reported characteristics of older adults and their caregivers were assessed from older adult and caregiver survey interviews. Older adult hospitalization over the subsequent 12 months was identified in Medicare claims. Multivariable Cox proportional hazards models adjusted for older adult characteristics and were stratified by dementia status. RESULTS: In this nationally representative cohort, 38% of older adults with disabilities were hospitalized over 12 months following interview. Increased hospitalization risk was associated with having a primary caregiver who helped with healthcare tasks (adjusted hazard ratio (aHR) = 1.22; 95% confidence interval (CI) = 1.05-1.40), reported physical strain (aHR = 1.21; 95% CI = 1.04-1.42), and provided more than 40 hours of care weekly (aHR = 1.26; 95% CI = 1.04-1.54 vs ≤20 hours). Having a caregiver who had helped for 4 years or longer (vs <1 year) was associated with 38% lower risk of hospitalization (aHR = 0.62; 95% CI = 0.49-0.79). Older adults with and without dementia had similar rates of hospitalization (39.5% vs 37.3%; P = .4), and caregiving factors were similarly associated with hospitalization regardless of older adults' dementia status. CONCLUSION: Select caregiving characteristics are associated with hospitalization risk among older adults with disability. Hospitalization risk reduction strategies may benefit from understanding and addressing caregiving circumstances.

Dissecting the Racial/Ethnic Disparity in Frailty in a Nationally Representative Cohort Study with Respect to Health, Income, and Measurement.

BACKGROUND: Racial/ethnic frailty prevalence disparities have been documented. Better elucidating how these operate may inform interventions to eliminate them. We aimed to determine whether physical frailty phenotype (PFP) prevalence disparities (i) are explained by health aspects, (ii) vary by income, or (iii) differ in degree across individual PFP criteria. METHODS: Data came from the 2011 National Health and Aging Trends Study baseline evaluation. The study sample (n = 7,439) included persons in all residential settings except nursing homes. Logistic regression was used to achieve aims (i)-(iii) listed above. In (i), health aspects considered were body mass index (BMI) status and number of chronic diseases. Analyses incorporated sampling weights and adjusted for sociodemographic factors. RESULTS: Comparisons are versus non-Hispanic whites: Non-Hispanic blacks (odds ratio [OR] = 1.46, 95% confidence interval [CI]: 1.21-1.76) and Hispanics (1.56, 1.20-2.03) continued to have higher odds of frailty after accounting for BMI status and number of chronic diseases. Non-Hispanic blacks had elevated odds of frailty in all income quartiles, including the highest (OR = 2.19, 1.24-3.397). Racial/ethnic disparities differed considerably across frailty criteria, ranging from a twofold increase in odds of slowness to a 25%-30% decrease in odds of self-reported exhaustion. CONCLUSIONS: BMI and disease burden do not explain racial/ethnic frailty disparities. Black-white disparities are not restricted to low-income groups. Racial/ethnic differences vary considerably by NHATS PFP criteria. Our findings support the need to better understand mechanisms underlying elevated frailty burden in older non-Hispanic black and Hispanic Americans, how phenotypic measures capture frailty in racial/ethnic subgroups and, potentially, how to create assessments more comparable by race/ethnicity.

Associations of insomnia symptoms with subsequent health services use among community-dwelling U.S. older adults.

STUDY OBJECTIVES: Determine the association of insomnia symptoms with subsequent health services use, in a representative sample of U.S. older adults. METHODS: Participants were 4,289 community-dwelling Medicare beneficiaries who had continuous fee-for-service Medicare coverage 30 days before, and 1 year after the National Health and Aging Trends Study (NHATS) Round 1 interview. Participants reported past-month insomnia symptoms (i.e. sleep onset latency >30 min, difficulty returning to sleep) which we categorized as 0, 1, or 2 symptoms. Outcomes were health services use within 1 year of interviews from linked Medicare claims: emergency department (ED) visits, hospitalizations, 30-day readmissions, home health care (all measured as yes/no), and number of hospitalizations and ED visits. RESULTS: Overall, 18.5% of participants were hospitalized, 28.7% visited the ED, 2.5% had a 30-day readmission, and 11.3% used home health care. After adjustment for demographics, depressive and anxiety symptoms, medical comorbidities, and BMI, compared to participants with no insomnia symptoms, those with two insomnia symptoms had a higher odds of ED visits (odds ratio [OR) = 1.60, 95% confidence interval [CI] = 1.24-2.07, p < 0.001), hospitalizations (OR = 1.29, 95% CI = 1.01-1.65, p < 0.05), and 30-day readmissions (OR = 1.88, 95% CI = 1.88-3.29, p < 0.05). Reporting 2 insomnia symptoms, versus no insomnia symptoms, was associated with a greater number of ED visits and hospitalizations (incidence rate ratio (IRR) = 1.52, 95% CI = 1.23-1.87, p < 0.001; IRR = 1.21, 95% CI = 1.02-1.44, p < 0.05, respectively) after adjusting for demographic and health characteristics. CONCLUSIONS: Among older adults, insomnia symptoms are associated with greater health services use, including emergency department use, hospitalization, and 30-day readmission. Targeting insomnia may lower health services use.

Race Differences in Characteristics and Experiences of Black and White Caregivers of Older Americans.

BACKGROUND AND OBJECTIVES: Racial disparities in health and socioeconomic characteristics of older adults have implications for the experiences of their family and unpaid caregivers, but knowledge to date has primarily drawn from convenience samples. Using a population-based sample, we examine associations between caregiver race and caregiving-related effects. RESEARCH DESIGN AND METHODS: Study participants include white (n = 992) and black (n = 556) respondents to the 2015 National Study of Caregiving who assisted community-dwelling older adults with disabilities who participated in the National Health and Aging Trends Study. Guided by Pearlin's Stress Process Model, hierarchical logistic regression models were constructed to examine race differences in caregiving-related effects after adjusting for caregiving context, stressors, and resources. RESULTS: Relative to white caregivers, blacks more often provided in excess of 40 hr of care per week (54.3% vs 38.6%) and more often cared for an older adult with dementia (27.1% vs 20.7%) who was living below the federal poverty line (31.7% vs 11.9%) or was Medicaid-eligible (42.2% vs 11.8%). Black caregivers more often used supportive services (32.9% vs 24.8%). In fully adjusted regression models, black caregivers were more likely to report gains and less likely to report emotional difficulty than whites. Service utilization did not attenuate caregiving-related emotional difficulty or participation restrictions, regardless of race. DISCUSSION AND IMPLICATIONS: Findings highlight caregiving disparities and counterintuitive differences in experiences and indicate the importance of identifying supports such as paid family leave and faith and community-based programming to better support community-dwelling low-income older adults and their family and unpaid caregivers.

Comparing Survey-Based Frailty Assessment to Medicare Claims in Predicting Health Outcomes and Utilization in Medicare Beneficiaries.

Objectives: To assess two models for the prediction of health utilization and functions using standardized in-person assessments of frailty and administrative claims-based geriatric risk measures among Medicare fee-for-service beneficiaries aged 65 years and above. Methods: Outcomes of hospitalizations, death, and functional help were investigated for participants in the 2011 National Health and Aging Trends Study. For each outcome, multivariable logistic regression model was used to investigate claims-based geriatric risk and survey-based frailty. Results: Both claims-based and survey-based models showed moderate discrimination. The c-statistic of the standardized frailty models ranged from 0.67 (for any hospitalization) to 0.84 (for any IADL [instrumental activities of daily living] help). Models using administrative data ranged from 0.71 (for any hospitalization) to 0.81 (for any IADL help). Discussion: Models based on existing administrative data appear to be as discriminate as survey-based models. Health care providers and insurance plans can effectively apply existing data resources to help identify high-risk individuals for potential care management interventions.

Financial Stress and Risk for Entry into Medicaid Among Older Adults.

BACKGROUND AND OBJECTIVES: Spending in the Medicaid program is a significant concern to both state and federal policy makers. Medicaid spending is driven by program enrollment and services use. Older adults with high health care needs incur a disproportionate proportion of program spending. This analysis identifies factors that place older Medicare beneficiaries at increased risk for entering into Medicaid. RESEARCH DESIGN AND METHODS: We use multinomial logistic regression and the 2011-2017 National Health and Aging Trends Study (NHATS) to examine the risks among older Medicare beneficiaries for entering into Medicaid over a 6-year follow-up period. We examine both time-invariant and time-varying factors to measure the impact of social and health and functioning changes at older ages. RESULTS: The risk of entry into Medicaid was higher for older adults who relocated to a nursing home (relative risk ratio [RRR]: 7.75; 95% confidence interval [CI]: 5.33-11.26) or other residential care setting (RRR: 1.36; 95% CI: 0.96-1.92) compared to those who remained in traditional community settings. Older adults who reported skipping a meal in the last month because there was not enough money to buy food were 2.4 times (95% CI: 1.10-5.21) more likely to enter Medicaid than those who did not. Similarly, older adults who reported not having enough money to pay household utility bills in the last year were 1.89 times (95% CI: 1.08-3.30) more likely to enter Medicaid. DISCUSSION AND IMPLICATIONS: Study findings suggest that trouble paying for basic needs increases the risk of entry into Medicaid. Further research is required to examine whether addressing these needs through improved access to social services that enable older adults to live safely in their home may delay or mitigate entry into Medicaid.

Family Caregiver Factors Associated With Emergency Department Utilization Among Community-Living Older Adults With Disabilities.

Background: Older adults with disability are frequent users of the emergency department (ED) and often rely on family caregiver support. We identify whether and which caregiver characteristics are associated with older adults' ED use. Methods: We use Cox proportional hazards regression to model the likelihood of all-cause ED use (defined as 1 or more visits within 12 months of survey) as a function of caregiver characteristics after adjusting for older adult sociodemographic and health characteristics. We draw from linked older adult and caregiver surveys and administrative claims, creating a sample of 2521 community-living older adults with mobility/self-care disability receiving care from a family or unpaid caregiver. Results: About half (52.5%) of older adults receiving mobility or self-care help incurred 1 or more ED visits within 12 months of interview. Adjusting for year of data collection, sociodemographic characteristics, and health status, these older adults were at greater risk of all-cause ED use if their primary caregiver provided greater than 40 hours of care per week (hazard ratio [HR] 1.22, 95% CI 1.04-1.43; P = .02), helped with health care tasks (HR 1.26; 95% CI 1.08-1.46; P < .01), or experienced physical strain (HR 1.18; 95% CI 1.03-1.36; P = .02). Conclusion: Caregiver strain, helping with health care tasks, and greater hours of help per week are associated with heightened risk of ED use among older adults receiving mobility or self-care help. Study findings suggest the potential benefit of caregiver assessment and support.

Medicare Spending and the Adequacy of Support With Daily Activities in Community-Living Older Adults With Disability: An Observational Study.

Background: Identifying factors that affect variation in health care spending among older adults with disability may reveal opportunities to better address their care needs while offsetting excess spending. Objective: To quantify differences in total Medicare spending among older adults with disability by whether they experience negative consequences due to inadequate support with household activities, mobility, or self-care. Design: Observational study of in-person interviews and linked Medicare claims. Setting: United States, 2015. Participants: 3716 community-living older adults who participated in the 2015 NHATS (National Health and Aging Trends Study) and survived for 12 months. Measurements: Total Medicare spending by spending quartile in multivariable regression models that adjusted for individual characteristics. Results: Negative consequences were experienced by 18.3% of participants with disability in household activities, 25.6% with mobility disability, and 20.0% with self-care disability. Median Medicare spending was higher for those who experienced negative consequences due to household ($4866 vs. $4095), mobility ($7266 vs. $4115), and self-care ($10 935 vs. $4436) disability versus those who did not. In regression-adjusted analyses, median spending did not differ appreciably for participants who experienced negative consequences in household activities ($338 [95% CI, -$768 to $1444]), but was higher for those with mobility ($2309 [CI, $208 to $4409]) and self-care ($3187 [CI, $432 to $5942]) disability. In the bottom-spending quartile, differences were observed for self-care only ($1460 [CI, $358 to $2561]). No differences were observed in the top quartile. Limitation: This observational study could not establish causality. Conclusion: Inadequate support for mobility and self-care is associated with higher Medicare spending, especially in the middle and lower ends of the spending distribution. Better support for the care needs of older adults with disability could offset some Medicare spending. Primary Funding Source: The Commonwealth Fund.

The Financial Hardship Faced by Older Americans Needing Long-Term Services and Supports.

Issue: In addition to medical care, individuals with functional or cognitive impairment often require long-term services and supports (LTSS), which Medicare does not cover. Little is known about the additional out-of-pocket expenses that individuals and their families incur to meet these needs. Goal: To analyze medical and LTSS spending among older Medicare beneficiaries, particularly the costs of assistive devices and personal care and the ways those costs are met. Methods: Descriptive analyses of the National Health and Aging Trends Study (NHATS), 2015. Key Findings and Conclusions: Beneficiaries with high LTSS needs have higher Medicare and out-of-pocket spending than those without such needs and are more likely to report that medical care makes up part of their credit card debt. Those with high LTSS needs are also more likely to report trouble paying for food, rent, utilities, medical care, and prescription drugs. Many older Medicare beneficiaries using LTSS are vulnerable to incurring substantial costs. Without an affordable, sustainable financing solution, Medicare beneficiaries with LTSS needs will continue to be at greater risk of delaying necessary care, being placed in a nursing home prematurely, and having to "spend down" into the Medicaid program.

Are Older Americans Getting the Long-Term Services and Supports They Need?

Issue: Older adults' needs have evolved and are no longer met by the Medicare program. With the recent passage of the Bipartisan Budget Act of 2018 (BBA), Medicare Advantage (MA) plans can now provide beneficiaries with nonmedical benefits, such as long-term services and supports (LTSS), which Medicare does not cover. Goal: To examine the use of LTSS among Medicare beneficiaries age 65 and older living in the community and explore differences by age, income, and other variables. Methods: Descriptive analyses of the National Health and Aging Trends Study (NHATS), 2015. Findings and Conclusions: Two-thirds of older adults living in the community use some degree of LTSS. Reliance on assistive devices and environmental modifications is high; however many adults, particularly dual-eligible beneficiaries, experience adverse consequences of not receiving care. Although the recent policy change allowing MA plans to offer LTSS benefits is an important step toward meeting the medical and nonmedical needs of Medicare beneficiaries, only the one-third of Medicare beneficiaries enrolled in MA plans stand to benefit. Accountable care organizations operating in traditional Medicare also should have the increased flexibility to provide nonmedical services.

Long-Term Nursing Home Entry: A Prognostic Model for Older Adults with a Family or Unpaid Caregiver.

OBJECTIVES: To comprehensively examine factors associated with long-term nursing home (NH) entry from 6 domains of older adult and family caregiver risk from nationally representative surveys and develop a prognostic model and a simple scoring system for use in risk stratification. DESIGN: Retrospective observational study. SETTING: National Long-Term Care Surveys 1999 and 2004 and National Health and Aging Trends Study 2011 and linked caregiver surveys. PARTICIPANTS: Community-living older adults receiving help with self-care disability and their primary family or unpaid caregiver (N=2,676). MEASUREMENTS: Prediction of long-term NH entry (>100 days or ending in death) by 24 months follow up, ascertained from Minimum Data Set assessments and dates of death from Medicare enrollment files. Risk factors were measured from survey responses. RESULTS: In total, 16.1% of older adults entered a NH. Our final model and risk scoring system includes 7 independent risk factors: older adult age (1 point/5 years), living alone (5 points), dementia (3 points), 3 or more of 6 self-care activities (2 points), caregiver age (45-64: 1 point, 65-74: 2 points, ≥75: 4 points), caregiver help with money management (2 points), and caregiver report of moderate (2 points) or high (4 points) strain. Using this model, participants were assigned to risk quintiles. Long-term NH entry was 7.0% in the lowest quintile (0-6 points), 20.4% in the middle 3 quintiles (7-14 points), and 30.9% in the highest quintile (15-22 points). The model was well calibrated and demonstrated moderate discrimination (c-statistic=0.670 in the original data, c-statistic=0.647 in bootstrapped samples, c-statistic=0.652 using the point-scoring system). CONCLUSION: We developed a prognostic model and simple scoring system that may be used to stratify risk of long-term NH entry of community-living older adults. Our model may be useful for population health and policy applications.

Late Transitions and Bereaved Family Member Perceptions of Quality of End-of-Life Care.

OBJECTIVES: To examine associations between healthcare transitions at the end of life (EOL; late transitions) and bereaved family members' and friends' assessment of EOL quality of care (QOC). DESIGN: National Health and Aging Trends Study (NHATS), a prospective cohort of Medicare enrollees aged 65 and older. SETTING: United States, all sites of death. PARTICIPANTS: Family members and close friends of decedents from NHATS Rounds 2 through 6 (N=1,653; weighted 6.0 million Medicare deaths). MEASUREMENTS: Multivariable logistic regression with survey weights was used to examine the association between having a late transition and reports of perceived unmet needs for symptom management, spiritual support, concerns with communication, and overall QOC. RESULTS: Seventeen percent of decedents had a late transition. Bereaved respondents for decedents experiencing late transitions were more likely to report that the decedent was treated without respect (21.3% vs 15.6%; adjusted odds ratio (AOR)=1.59, 95% confidence interval (CI)=1.09-2.33), had more unmet needs for spiritual support (67.4% v 55.2%; AOR=1.48, 95% CI=1.03-2.13), and were more likely to report they were not kept informed about the person's condition (31.0% vs 20.9%; AOR=1.54, 95% CI=1.07-2.23). Bereaved respondents were less likely to rate QOC as excellent when there was a late transition (43.6% vs 48.2%; AOR=0.79, 95% CI=0.58-1.06). Subgroup analyses of those experiencing a transition between a nursing home and hospital (13% of all late transitions) revealed such transitions to be associated with even worse QOC. CONCLUSION: Transitions in the last 3 days of life are associated with more unmet needs, higher rate of concerns, and lower rating of QOC than when such late transitions are absent, especially when that transition is between a nursing home and hospital.

Can Older Adults Accurately Report Their Use of Physical Rehabilitation Services?

OBJECTIVE: To explore the accuracy of rehabilitation service use reports by older adults as well as variation in accuracy by demographic characteristics, time since use, duration, and setting (inpatient, outpatient, home). DESIGN: Longitudinal observational study. SETTING: Participants' homes. PARTICIPANTS: Community-dwelling adults ages 65 and older (N=4228) in the 2015 National Health and Aging Trends Study who were enrolled in Medicare Parts A and B for 12 months before their interview. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Respondents were asked whether they received rehabilitation services in the past year and the duration and location of services. Healthcare Common Procedure Coding System codes and Revenue Center codes were used to identify Medicare-eligible rehabilitation service. RESULTS: Survey-based reports and Medicare claims yielded similar estimates of rehabilitation use over the past year. Self-reported measures had high sensitivity (77%) and positive predictive value (80%) and even higher specificity and negative predictive value (approaching 95%). However, in adjusted models, sensitivity was lower for black enrollees, the very old, and those with lower education levels. CONCLUSIONS: Survey-based measures of rehabilitation accurately captured use over the past year, but differential reporting should be considered when characterizing rehabilitation use in certain subgroups of older Americans.

Rehabilitation Utilization for Falls Among Community-Dwelling Older Adults in the United States in the National Health and Aging Trends Study.

OBJECTIVE: To determine the characteristics of community-dwelling older adults receiving fall-related rehabilitation. DESIGN: Cross-sectional analysis of the fifth round (2015) of the National Health and Aging Trends Study (NHATS). Fall-related rehabilitation utilization was analyzed using weighted multinomial logistic regression with SEs adjusted for the sample design. SETTING: In-person interviews of a nationally representative sample of community-dwelling older adults. PARTICIPANTS: Medicare beneficiaries from NHATS (N=7062). INTERVENTIONS: Not applicable. MAIN OUTCOMES MEASURES: Rehabilitation utilization categorized into fall-related rehabilitation, other rehabilitation, or no rehabilitation. RESULTS: Fall status (single fall: odds ratio [OR]=2.96; 95% confidence interval [CI], 1.52-5.77; recurrent falls: OR=14.21; 95% CI, 7.45-27.10), fear of falling (OR=3.11; 95% CI, 1.90-5.08), poor Short Physical Performance Battery scores (score 0: OR=6.62; 95% CI, 3.31-13.24; score 1-4: OR=4.65; 95% CI, 2.23-9.68), and hip fracture (OR=3.24; 95% CI, 1.46-7.20) were all associated with receiving fall-related rehabilitation. Lower education level (less than high school diploma compared with 4-y college degree: OR=.21; 95% CI, .11-.40) and Hispanic ethnicity (OR=.37; 95% CI, .15-.87) were associated with not receiving fall-related rehabilitation. CONCLUSIONS: Hispanic older adults and older adults who are less educated are less likely to receive fall-related rehabilitation. Recurrent fallers followed by those who fell once in the past year were more likely to receive fall-related rehabilitation than are older adults who have not had a fall in the past year.

Successful Aging Through Successful Accommodation With Assistive Devices.

OBJECTIVES: To provide a profile of older adults who successfully accommodate declines in capacity by using assistive devices. METHOD: Using the National Health and Aging Trends Study, we provide national estimates of prevalent, incident, and persistent successful accommodation of mobility and self-care activity limitations. For incident and persistent accommodation groups, we describe their subjective wellbeing and participation restrictions, health and functioning, demographic and socioeconomic characteristics, and acquisition of assistive devices and environmental features. We estimate regression models predicting incident and persistent successful accommodation and the extent of wellbeing and participation restrictions for incident and persistent groups (vs. those who are fully able). RESULTS: Nearly one-quarter of older adults have put in place accommodations that allow them to carry out daily activities with no assistance or difficulty. In adjusted models, incident and persistent successful accommodation is more common for those ages 80-89, those with more children, and those living in homes with environmental features already installed; wellbeing levels for these groups are similar and participation restrictions only slightly below those who are fully able. DISCUSSION: A focus on facilitating successful accommodation among those who experience declines in capacity may be an effective means of promoting participation and wellbeing in later life.

A National Profile of Family and Unpaid Caregivers Who Assist Older Adults With Health Care Activities.

IMPORTANCE: Family and unpaid caregivers commonly help older adults who are at high risk for poorly coordinated care. OBJECTIVE: To examine how caregivers' involvement in older adults' health care activities relates to caregiving responsibilities, supportive services use, and caregiving-related effects. DESIGN, SETTING, AND PARTICIPANTS: A total of 1739 family and unpaid caregivers of 1171 community-dwelling older adults with disabilities who participated in the 2011 National Health and Aging Trends Study (NHATS) and National Study of Caregiving (NSOC). MAIN OUTCOMES AND MEASURES: Caregiving-related effects, including emotional, physical, and financial difficulty; participation restrictions in valued activities; and work productivity loss. EXPOSURES: Caregivers assisting older adults who provide substantial, some, or no help with health care, defined by coordinating care and managing medications (help with both, either, or neither activity, respectively). RESULTS: Based on NHATS and NSOC responses from 1739 family and unpaid caregivers of 1171 older adults with disabilities, weighted estimates were produced that accounted for the sampling designs of each survey. From these weighted estimates, 14.7 million caregivers assisting 7.7 million older adults, 6.5 million (44.1%) provided substantial help, 4.4 million (29.8%) provided some help, and 3.8 million (26.1%) provided no help with health care. Almost half (45.5%) of the caregivers providing substantial help with health care assisted an older adult with dementia. Caregivers providing substantial help with health care provided more hours of assistance per week than caregivers providing some or no help (28.1 vs 15.1 and 8.3 hours, P < .001 for both). The use of supportive services was low but was greater among caregivers providing substantial vs some or no help (26.7% vs 15.5% and 7.6%, P < .001 for both). In multivariable regression models adjusting for older adults' function and caregivers' sociodemographic and health characteristics, caregivers providing substantial help with health care were significantly more likely to experience emotional difficulty (adjusted odds ratio [aOR], 1.79; 95% CI, 1.20-2.66), physical difficulty (aOR, 2.03; 95% CI, 1.39-2.97), and financial difficulty (aOR, 2.21; 95% CI, 1.52-3.22) than caregivers providing no help. Compared with caregivers providing no help with health care activities, caregivers providing substantial help with health care activities were more than 5 times as likely to experience participation restrictions in valued activities (aOR, 5.32; 95% CI, 3.31-8.59) and more than 3 times as likely to experience work productivity loss (aOR, 3.14; 95% CI, 1.40-7.02). CONCLUSIONS AND RELEVANCE: Family caregivers providing substantial assistance with health care experience significant emotional difficulty and role-related effects, yet only one-quarter use supportive services.
