RESUMEN

OBJECTIVE: While racial, ethnic, and socioeconomic group disparities in cognitive impairment and dementia prevalence are well-documented among community-dwelling older adults, little is known about these disparity trends among older adults receiving Medicaid-funded home- and community-based services (HCBS) in lieu of nursing home admission. The authors determined how dementia prevalence and cognitive impairment severity compare by race, ethnicity, educational attainment, and neighborhood context in a Medicaid HCBS population. DESIGN/SETTING: A cross-sectional study in Connecticut. PARTICIPANTS: Adults age ≥65 in the HCBS program, January-March 2019 (N = 3,520). MEASUREMENTS: The data source was Connecticut's HCBS program Universal Assessment tool. The authors employed two outcomes: Cognitive Performance Scale (CPS2), a 9-point measure ranging from cognitively intact-very severe impairment; and presence or not of either diagnosed dementia or CPS2 score ≥4 (major impairment). Neighborhood context was measured using the Social Vulnerability Index (SVI). RESULTS: Cohort characteristics: 75.7% female; mean(SD) age = 79.1(8.2); Non-Hispanic White = 47.8%; Hispanic = 33.6%; Non-Hispanic Black = 15.9%. Covariate-adjusted multivariate analyses revealed no dementia/major impairment prevalence differences among White, Black, and Hispanic individuals, but impairment severity was greater among Hispanic participants (b = 0.22; p = 0.02). People with more than HS education had less severe impairment (b = -0.12; p <0.001) and lower likelihood of dementia/major impairment (AOR = 0.61; p <0.001). Dementia/major impairment likelihood and impairment severity were greater in less socially vulnerable neighborhoods. CONCLUSION: Racial and ethnic group differences in cognitive impairment are less pronounced in Medicaid-funded HCBS cohorts than in other community-dwelling older adult cohorts. SVI results suggest that, among other possible explanations, older adults with dementia may move to lower social vulnerability neighborhoods where supportive family members reside.

RESUMEN

BACKGROUND: Some studies suggest that ambient particulate air pollution is associated with cognitive decline. However, the findings are mixed, and there is no relevant research examining the influences of ultrafine particles (UFP), which may have more toxicity than larger particles. We therefore conducted this study to investigate whether residential UFP exposure is associated with cognitive decline using data from the Alzheimer's Disease Research Centers in the United States. METHODS: This is a longitudinal study of participants who were aged 65 years and older and had normal cognitive status at baseline. Residential UFP exposure, expressed as particle number concentrations (PNC), was assessed in 2016-2017 using a nationwide land use regression model, and was assigned to each participant using their 3-digit residential ZIP codes. Cognitive functions including memory, attention, language, executive function, and global function were assessed annually using 15 neuropsychological tests from March 2015 to February 2022. Linear mixed-effects models were used to examine the associations after adjustment for covariates including baseline age, sex, APOE ε4 status, race, education, smoking status, history of diabetes, quartiles of neighborhood median household income, and interaction terms of follow-up time with each covariate. RESULTS: This study included 5646 participants (mean age 76 years, 65% female). On average, each participant had 4 annual visits. When PNC was treated as a continuous variable, there were no statistically or clinically significant changes in annual decline of each cognitive function in relation to an interquartile range elevation in PNC (4026 particles/cm3). Similarly, when PNC was treated as a categorical variable including five exposure groups, there were no linear exposure-response trends in annual decline of each cognitive function across the five exposure groups. CONCLUSIONS: This study found no meaningful associations between residential UFP exposure and cognitive decline in global and domain-specific functions. There is a need for further research that assigns UFP exposure at a finer geographic scale.

RESUMEN

The purpose of this scoping review is to identify conceptual and theoretical resilience models, types of resilience measures, and outcomes regarding resilience in relation to older adults with multimorbidity. PubMed, Embase, CINAHL, and PsycINFO were searched, and we identified 14 studies to July 2021. Most models operationalize resilience as dependent on the social and environmental context of older adults. Three of the five resilience measures in the included studies are used to evaluate general resilience. They are primarily psychological or psychosocial in nature, and measuring physical resilience therefore may help to better understand individuals' ability to cope with the physical challenges associated with various chronic diseases. Quality of life and physical activity were common outcomes in studies of resilience. Findings highlight the need for studies that incorporate physiological measures or physical properties of resilience and longitudinal studies that capture the dynamic process of resilience in older adults with multimorbidity.

RESUMEN

IMPORTANCE: treatment of dementia in individuals with comorbidities is complex, leading to potentially inappropriate prescribing (PIP). The impact of PIP in this population is unknown. OBJECTIVE: to estimate the rate of PIP and its effect on adverse health outcomes (AHO). DESIGN: retrospective cohort. SETTING: primary care electronic health records linked to hospital discharge data from England. SUBJECTS: 11,175 individuals with dementia aged over 65 years in 2016 and 43,463 age- and sex-matched controls. METHODS: Screening Tool of Older Persons' Prescriptions V2 defined PIP. Logistic regression tested associations with comorbidities at baseline, and survival analyses risk of incident AHO, adjusted for age, gender, deprivation and 14 comorbidities. RESULTS: the dementia group had increased risk of PIP (73% prevalence; odds ratio [OR]: 1.92; confidence interval [CI]: 83-103%; P < 0.01) after adjusting for comorbidities. Most frequent PIP criteria were related to anti-cholinergic drugs and therapeutic duplication. Risk of PIP was higher in patients also diagnosed with coronary-heart disease (odds OR: 2.17; CI: 1.91-2.46; P < 0.01), severe mental illness (OR: 2.09; CI: 1.62-2.70; P < 0.01); and depression (OR: 1.81; CI: 1.62-2.01; P < 0.01). During follow-up (1 year), PIP was associated with increased all-cause mortality (hazard ratio: 1.14; CI: 1.02-1.26; P < 0.02), skin ulcer and pressure sores (hazard ratio: 1.66; CI: 1.12-2.46; P < 0.01), falls (hazard ratio: 1.37; CI: 1.15-1.63; P < 0.01), anaemia (hazard ratio: 1.61; CI: 1.10-2.38; P < 0.02) and osteoporosis (hazard ratio: 1.62; CI: 1.02-2.57; P < 0.04). CONCLUSION: patients with dementia frequently receive PIPs, and those who do are more likely to experience AHO. These results highlight the need to optimise medication in dementia patients, especially those with comorbidities.

RESUMEN

BACKGROUND: Hospitalization is a difficult experience, especially for patients with dementia. Understanding whether better continuity of care (COC) reduces hospitalizations can indicate interventions that might help curb hospitalizations. OBJECTIVE: To estimate the causal impact of COC on hospitalizations and different reasons for hospitalization among community-dwelling older veterans with dementia. RESEARCH DESIGN: Population-based observational study using nationwide Veterans Health Administration data linked to Medicare claims in Fiscal Years (FYs) 2014-2015. To account for unobserved confounders we used an instrumental variable for COC-whether veteran changed residence by more than 10 miles. SUBJECTS: Community-dwelling veterans with dementia aged 66 and older, enrolled in Traditional Medicare (n=105,528). MEASURES: Bice-Boxerman Continuity of Care (BBC) index (0-worst to 1-best COC); binary indicators of any hospitalization for all causes, for ambulatory care sensitive conditions (ACSCs) and for reasons grouped by major diagnostic category. RESULTS: The mean BBC in FY 2014 was 0.32 (SD, 0.23). In FY 2015 43.3% of the cohort veterans were hospitalized. A 0.1 higher BBC resulted in 2.4% (95% confidence interval, 0.5%-4.4%) lower probability of hospitalization for all causes. BBC was not associated with hospitalization for ACSCs. Grouped by major diagnostic category, a 0.1 higher BBC resulted in 3.8% (95% confidence interval, 2.1%-5.4%) lower probability of hospitalization for neuropsychiatric diseases/disorders, with no impact on hospitalizations for circulatory, respiratory, infectious, kidney and urinary, digestive, musculoskeletal, and endocrine-metabolic diseases/disorders. CONCLUSIONS: Among community-dwelling older veterans with dementia, better COC resulted in less hospitalizations, and this effect was primarily due to less hospitalization for neuropsychiatric diseases/disorders but not hospitalization for ACSCs, or other hospitalization reasons.

RESUMEN

IMPORTANCE: risk factors for delirium in hospital inpatients are well established, but less is known about whether delirium occurring in the community or during an emergency admission to hospital care might be predicted from routine primary-care records. OBJECTIVES: identify risk factors in primary-care electronic health records (PC-EHR) predictive of delirium occurring in the community or recorded in the initial episode in emergency hospitalisation. Test predictive performance against the cumulative frailty index. DESIGN: Stage 1: case-control; Stages 2 and 3: retrospective cohort. SETTING: clinical practice research datalink: PC-EHR linked to hospital discharge data from England. SUBJECTS: Stage 1: 17,286 patients with delirium aged ≥60 years plus 85,607 controls. Stages 2 and 3: patients ≥ 60 years (n = 429,548 in 2015), split into calibration and validation groups. METHODS: Stage 1: logistic regression to identify associations of 110 candidate risk measures with delirium. Stage 2: calibrating risk factor weights. Stage 3: validation in independent sample using area under the curve (AUC) receiver operating characteristic. RESULTS: fifty-five risk factors were predictive, in domains including: cognitive impairment or mental illness, psychoactive drugs, frailty, infection, hyponatraemia and anticholinergic drugs. The derived model predicted 1-year incident delirium (AUC = 0.867, 0.852:0.881) and mortality (AUC = 0.846, 0.842:0.853), outperforming the frailty index (AUC = 0.761, 0.740:0.782). Individuals with the highest 10% of predicted delirium risk accounted for 55% of incident delirium over 1 year. CONCLUSIONS: a risk factor model for delirium using data in PC-EHR performed well, identifying individuals at risk of new onsets of delirium. This model has potential for supporting preventive interventions.

RESUMEN

Importance: Disability persists after hip fracture in older persons. Current rehabilitation may not be sufficient to restore ability to walk in the community. Objective: To compare a multicomponent home-based physical therapy intervention (training) with an active control on ability to walk in the community. Design, Setting, and Participants: Parallel, 2-group randomized clinical trial conducted at 3 US clinical centers (Arcadia University, University of Connecticut Health Center, and University of Maryland, Baltimore). Randomization began on September 16, 2013, and ended on June 20, 2017; follow-up ended on October 17, 2017. Patients aged 60 years and older were enrolled after nonpathologic, minimal trauma hip fracture, if they were living in the community and walking without human assistance before the fracture, were assessed within 26 weeks of hospitalization, and were not able to walk during daily activities at the time of enrollment. A total of 210 participants were randomized and reassessed 16 and 40 weeks later. Interventions: The training intervention (active treatment) (n = 105) included aerobic, strength, balance, and functional training. The active control group (n = 105) received transcutaneous electrical nerve stimulation and active range-of-motion exercises. Both groups received 2 to 3 home visits from a physical therapist weekly for 16 weeks; nutritional counseling; and daily vitamin D (2000 IU), calcium (600 mg), and multivitamins. Main Outcomes and Measures: The primary outcome (community ambulation) was defined as walking 300 m or more in 6 minutes at 16 weeks after randomization. The study was designed to test a 1-sided hypothesis of superiority of training compared with active control. Results: Among 210 randomized participants (mean age, 80.8 years; 161 women [76.7%]), 197 (93.8%) completed the trial (187 [89.0%] by completing the 6-minute walk test at 16 weeks and 10 [4.8%] by adjudication of the primary outcome). Among these, 22 of 96 training participants (22.9%) and 18 of 101 active control participants (17.8%) (difference, 5.1% [1-sided 97.5% CI, -∞ to 16.3%]; 1-sided P = .19) became community ambulators. Seventeen training participants (16.2%) and 15 control participants (14.3%) had 1 or more reportable adverse events during the intervention period. The most common reportable adverse events reported were falls (training: 6 [5.7%], control: 4 [3.8%]), femur/hip fracture (2 in each group), pneumonia (training: 2, control: 0), urinary tract infection (training: 2, control: 0), dehydration (training: 0, control: 2), and dyspnea (training: 0, control: 2). Conclusions and Relevance: Among older adults with a hip fracture, a multicomponent home-based physical therapy intervention compared with an active control that included transcutaneous electrical nerve stimulation and active range-of-motion exercises did not result in a statistically significant improvement in the ability to walk 300 m or more in 6 minutes after 16 weeks. Trial Registration: ClinicalTrials.gov Identifier: NCT01783704.

RESUMEN

This study examined experiences of 156 informal caregivers of older adults who transitioned to the community through the Connecticut Money Follows the Person (MFP) Rebalancing Demonstration after prolonged nursing home stays. Caregiver burden, positive aspects of caregiving, depressive symptoms, anxiety, and comparative subjective stress were examined in relation to caregiver demographics and care receiver characteristics with a cross-sectional survey. Caregivers reported low burden, depressive symptoms, and anxiety, and fairly high levels of positive aspects of caregiving and satisfaction with community services. Most caregivers were less stressed compared to the time the care recipient was in, or before they entered, a nursing home. Live-in caregivers experienced more positive aspects of caregiving, but adult children reported higher burden than other caregivers. Unmet service needs also increased caregiver burden. Programs like MFP are a viable option with broadly positive outcomes from a caregiver's perspective. Enthusiasm for increasing access to community care is growing for older adults who otherwise would reside in nursing homes for extended periods. Identifying unmet service needs and needs for targeted functional support could further enhance caregiver experiences and contribute to the successful transition of older adults to the community.

RESUMEN

INTRODUCTION: Under the U.S. national Alzheimer's plan, the National Institutes of Health identified milestones required to meet the plan's biomedical research goal (Goal 1). However, similar milestones have not been created for the goals on care (Goal 2) and support (Goal 3). METHODS: The Alzheimer's Association convened a workgroup with expertise in clinical care, long-term services and supports, dementia care and support research, and public policy. The workgroup reviewed the literature on Alzheimer's care and support; reviewed how other countries are addressing the issue; and identified public policies needed over the next 10 years to achieve a more ideal care and support system. RESULTS: The workgroup developed and recommended 73 milestones for Goal 2 and 56 milestones for Goal 3. DISCUSSION: To advance the implementation of the U.S. national Alzheimer's plan, the U.S. government should adopt these recommended milestones, or develop similar milestones, to be incorporated into the national plan.

RESUMEN

BACKGROUND: We sought to investigate the relationship between neuroticism and depression in an elderly cohort. In this paper, we describe the methods of an National Institute of Mental Health-NIMH-supported study and present findings among the cohort enrolled to date. METHODS: We used the NEO Personality Inventory to assess neuroticism, and we employed several cognitive neuroscience-based measures to examine emotional control. RESULTS: Compared with a group of 27 non-depressed older control subjects, 33 older depressed subjects scored higher on measures of state and trait anxiety and neuroticism. On our experimental neuroscience-based measures, depressed subjects endorsed more negative words compared with controls on an emotional characterization test. In addition, we found a significant group-by-congruency effect on an emotional interference test where subjects were asked to identify the face's emotional expression while ignoring the words "fear" or "happy" labeled across the face. CONCLUSION: Thus, in this preliminary work, we found significant differences in measures of neuroticism and emotional controls among older adults with and without depression.

RESUMEN

BACKGROUND: Identifying effective and accessible interventions for dementia caregivers is critical as dementia prevalence increases. OBJECTIVE: Examine the effects of a telephone-based intervention on caregiver well-being. DESIGN: Randomized, controlled trial. SETTING: Academic medical center. PARTICIPANTS: Two hundred and fifty distressed, family, dementia caregivers. INTERVENTION: Caregivers randomized to receive 16 telephone contacts over 6 months of either the Family Intervention: Telephone Tracking-Caregiver (FITT-C) or Telephone Support (TS). OUTCOME: Primary outcome variables were family caregivers' depressive symptoms, burden, and reactions to care recipients' behavior problems at 6 months. RESULTS: The FITT-C intervention resulted in significantly improved caregiver depressive symptoms (P = .003; 27% net improvement) and less severe reactions to care-recipient depressive behaviors (P = .009; 29% net improvement) compared with the control condition (TS). CONCLUSION: An entirely telephone-based intervention improves caregivers' depressive symptoms and reactions to behavior problems in the care recipient and is comparable with reported results of face-to-face interventions.

RESUMEN

Pain medication is commonly used among older adults with arthritis, elevating the risk of falling. We examined fall risks related to the frequency of taking pain medication among community-dwelling older adults with arthritis by analyzing a nationally representative sample of community-dwelling Medicare beneficiaries aged >65 with self-reported arthritis (n = 4,225) in the 2015 National Health and Aging Trends Study. The survey-weighted logistic regression revealed that after controlling for confounding factors, recent falls were associated with taking pain medication daily compared to never (OR = 1.45, 95% CI: 1.06, 1.96). The other categories of medication frequency, compared to never, were not associated with fall risk. Findings suggest that more prudent use of pain medication should be stressed by health care providers for older adults with arthritis to help reduce the risk of falls and fall injuries. Nonpharmacological pain management is encouraged to support active living among older adults with arthritis.

RESUMEN

Objectives: The purpose of this study was to evaluate the psychometric properties of the modified 25-item Resilience Scale (RS-25) in older adults post-hip fracture using Rasch analysis. Methods: This was a descriptive study using baseline data from the Seventh Baltimore Hip Studies (BHS-7). There were 339 hip fracture patients included in this analysis. Results: Findings suggest there was support for reliability of the measure based on person and item separation index. The INFIT and OUTFIT statistics for testing validity were all in the acceptable range indicating that each item on the modified RS-25 fits the appropriate concept. There was no evidence of Differential Item Functioning (DIF) between genders. Conclusions: This study demonstrated evidence that the modified RS-25 is a reliable and valid measure to evaluate resilience among older adults post-hip fracture and therefore can be used in this population in clinical practice and research.

RESUMEN

This study aimed to test a model of factors associated with resilience and physical activity post-hip fracture and compare model fit between men and women. We used data from the seventh Baltimore Hip Study that included 339 participants. Model testing indicated that health status (men: ß = .237, p = .002; women: ß = .265, p = <.001), depression (men: ß = -.245, p = .001; women: ß = -.241, p = <.001), and optimism (men: ß = .320, p = <.001; women: ß = .282, p = <.001) were associated with resilience in men and women, but resilience was only associated with physical activity in men (ß = .203, p = .038) and not in women. Social interaction was related to physical activity only among women (ß = .206, p = .044). This study provides support for the relationship between resilience and physical activity at least among men.

RESUMEN

The focus of aging research has shifted from increasing lifespan to enhancing healthspan to reduce the time spent living with disability. Despite significant efforts to develop biomarkers of aging, few studies have focused on biomarkers of healthspan. We developed a proteomics-based signature of healthspan (healthspan proteomic score (HPS)) using data from the UK Biobank Pharma Proteomics Project (53,018 individuals and 2920 proteins). A lower HPS was associated with higher mortality risk and several age-related conditions, such as COPD, diabetes, heart failure, cancer, myocardial infarction, dementia, and stroke. HPS showed superior predictive accuracy for these outcomes compared to chronological age and biological age measures. Proteins associated with HPS were enriched in hallmark pathways such as immune response, inflammation, cellular signaling, and metabolic regulation. Our findings demonstrate the validity of HPS, making it a valuable tool for assessing healthspan and as a potential surrogate marker in geroscience-guided studies.

RESUMEN

Beyond mere prognostication, optimal biomarkers of aging provide insights into qualitative and quantitative features of biological aging and might, therefore, offer useful information for the testing and, ultimately, clinical use of gerotherapeutics. We aimed to develop a proteomic aging clock (PAC) for all-cause mortality risk as a proxy of biological age. Data were from the UK Biobank Pharma Proteomics Project, including 53,021 participants aged between 39 and 70 years and 2,923 plasma proteins assessed using the Olink Explore 3072 assay®. The Spearman correlation between PAC proteomic age and chronological age was 0.77. A total of 10.9% of the participants died during a mean follow-up of 13.3 years, with the mean age at death 70.1 years. We developed a proteomic aging clock (PAC) for all-cause mortality risk as a surrogate of BA using a combination of least absolute shrinkage and selection operator (LASSO) penalized Cox regression and Gompertz proportional hazards models. PAC showed robust age-adjusted associations and predictions for all-cause mortality and the onset of various diseases in general and disease-free participants. The proteins associated with PAC were enriched in several processes related to the hallmarks of biological aging. Our results expand previous findings by showing that age acceleration, based on PAC, strongly predicts all-cause mortality and several incident disease outcomes. Particularly, it facilitates the evaluation of risk for multiple conditions in a disease-free population, thereby, contributing to the prevention of initial diseases, which vary among individuals and may subsequently lead to additional comorbidities.

RESUMEN

The pipeline from discovery to testing and then implementing evidence-based innovations in real-world contexts may take 2 decades or more to achieve. Implementation science innovations, such as hybrid studies that combine effectiveness and implementation research questions, may help to bridge the chasm between intervention testing and implementation in dementia care. This paper describes hybrid effectiveness studies and presents 3 examples of dementia care interventions conducted in various community-based settings. Studies that focus on outcomes and implementation processes simultaneously may result in a truncated and more efficient implementation pipeline, thereby providing older persons, their families, health care providers, and communities with the best evidence to improve quality of life and care more rapidly. We offer post-acute and long-term care researchers considerations related to study design, sampling, data collection, and analysis that they can apply to their own dementia and other chronic disease care investigations.

RESUMEN

BACKGROUND: Many older adults become dependent in one or more activities of daily living (ADLs: dressing, bathing, transferring, eating, toileting) when hospitalized, and their prognosis after discharge is unclear. OBJECTIVE: To develop a prognostic index to estimate one-year probabilities of recovery, dependence or death in older hospitalized patients who are discharged with incident ADL dependence. DESIGN: Retrospective cohort study. PARTICIPANTS: 449 adults aged ≥ 70 years hospitalized for acute illness and discharged with incident ADL dependence. MAIN MEASURES: Potential predictors included demographics (age, sex, race, education, marital status), functional measures (ADL dependencies, instrumental activities of daily living [IADL] dependencies, walking ability), chronic conditions (e.g., congestive heart failure, dementia, cancer), reason for admission (e.g., neurologic, cardiovascular), and laboratory values (creatinine, albumin, hematocrit). Multinomial logistic regression was used to develop a prognostic index for estimating the probabilities of recovery, disability or death over 1 year. Discrimination of the index was assessed for each outcome based on the c statistic. KEY RESULTS: During the year following hospitalization, 36 % of patients recovered, 27 % remained dependent and 37 % died. Key predictors of recovery, dependence or death were age, sex, number of IADL dependencies 2 weeks prior to admission, number of ADL dependencies at discharge, dementia, cancer, number of other chronic conditions, reason for admission, and creatinine levels. The final prognostic index had good to excellent discrimination for all three outcomes based on the c statistic (recovery: 0.81, dependence: 0.72, death: 0.78). CONCLUSIONS: This index accurately estimated the probabilities of recovery, dependence or death in adults aged 70 years or older who were discharged with incident disability following hospitalization. This tool may be useful in clinical settings to guide care discussions and inform decision-making related to post-hospitalization care.

RESUMEN

Medicaid-funded home and community-based services (HCBSs) reach large numbers of individuals living with dementia who would otherwise reside in nursing homes with Medicaid funding. Medicaid HCBSs also often augment care provided by family and other informal caregivers to individuals living with dementia. Although Medicaid-funded HCBSs are offered in most states in lieu of nursing home care, they have been largely overlooked as health care system partners for implementation and testing of evidence-based dementia care interventions using embedded pragmatic clinical trial (ePCT) designs. In this article, we make the case for the importance of Medicaid-funded HCBSs as dementia care ePCT partners because of the volume of vulnerable clients with dementia served and the potential positive impacts that evidence-based dementia care programs can have on clients and their informal caregivers. This article first characterizes the Medicaid HCBS setting in terms of populations served and organizational arrangements across states. We then characterize strengths and potential limitations presented by Medicaid HCBSs as settings within which to implement dementia care ePCTs, using as a conceptual framework the Pragmatic-Explanatory Continuum Indicator Summary (PRECIS-2) tool and its domains. We draw on our experiences implementing the Care of Persons with Dementia in their Environments (COPE) program in a statewide Medicaid HCBS setting to highlight how these potential ePCT partners can help optimize pragmatic approaches to several PRECIS-2 domains. We found that partners are especially effective in implementing pragmatic ways to determine eligibility for evidence-based dementia care programs; assist with recruitment of eligible individuals; incorporate dementia care interventions into the range of existing HCBSs; and track outcomes relevant to persons living with dementia, caregivers, HCBS providers, and Medicaid insurance stakeholders. We conclude with recommendations for researchers, potential ePCT partners, and policymakers to help facilitate the growth of dementia care ePCTs in Medicaid HCBS settings across the United States.
