Net Worth Predicts Symptom Burden at the End of Life

Objectives: To explore the predictors of symptom burden at the end of life. Design: Observational, secondary analysis of Health and Retirement Study (HRS) data. Setting: USA. Participants: Two thousand six hundred four deceased, older adults. Methods: Multivariate Poisson and logistic regression to explore the relationship between sociodemographic and clinical factors with symptoms. Results: Fatigue, pain, dyspnea, depression, and anorexia were common and severe; 58% of participants experienced more than 3 of these during their last year of life. Sociodemographic and clinical factors were associated with the number of symptoms as well as the presence of pain, depression, and dyspnea alone. Decedents in the highest quartile of net worth had fewer symptoms (incident rate ratio [IRR] 0.90, confidence interval [CI] 0.85–0.96) and less pain (odds ratio [OR] 0.66, CI 0.51–0.85) than comparisons did. Patients with cancer experienced more pain (OR 2.02, CI 1.62–2.53) and depression (OR 1.31, CI 1.07–1.61). Patients experienced more depression (OR 2.37, CI 1.85–3.03) and dyspnea (OR 1.40, CI 1.09–1.78). Limitation: Use of proxy reports for primary data. Conclusion: Older Americans experience a large symptom burden in the last year of life, largely with treatable symptoms such as pain, dyspnea, and depression. The adequacy of symptom control relates to clinical factors as well as net worth. This association between symptoms and wealth suggests that access to health care and other social services beyond those covered by Medicare may be important in decreasing symptom burden at the end of life.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/63106/1/jpm.2005.8.827.pd

Informal Caregiving Time and Costs for Urinary Incontinence in Older Individuals in the United States

To obtain nationally representative estimates of the additional time, and related cost, of informal caregiving associated with urinary incontinence in older individuals. DESIGN: Multivariate regression models using data from the 1993 Asset and Health Dynamics Study, a nationally representative survey of people aged 70 and older (N = 7,443). SETTING: Community-dwelling older people. PARTICIPANTS: National population-based sample of community-dwelling older people. MEASUREMENTS: Weekly hours of informal caregiving, and imputed cost of caregiver time, for community-dwelling older people who reported (1) no unintended urine loss, (2) incontinence that did not require the use of absorbent pads, and (3) incontinence that required the use of absorbent pads. RESULTS: Thirteen percent of men and 24% of women reported incontinence. After adjusting for sociodemographics, living situation, and comorbidities, continent men received 7.4 hours per week of care, incontinent men who did not use pads received 11.3 hours, and incontinent men who used pads received 16.6 hours ( P < .001). Women in these groups received 5.9, 7.6, and 10.7 hours ( P < .001), respectively. The additional yearly cost of informal care associated with incontinence was $1,700 and$4,000 for incontinent men who did not and did use pads, respectively, whereas, for women in these groups, the additional yearly cost was $700 and$2,000. Overall, this represents a national annual cost of more than $6 billion for incontinence-related informal care. CONCLUSIONS: The quantity of informal caregiving for older people with incontinence and its associated economic cost are substantial. Future analyses of the costs of incontinence, and the cost-effectiveness of interventions to prevent or treat incontinence, should consider the significant informal caregiving costs associated with this condition.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66038/1/j.1532-5415.2002.50170.x.pd

Out-of-Pocket Health-Care Expenditures among Older Americans with Cancer

Objective:  There is currently limited information regarding the out-of-pocket expenditures (OOPE) for medical care made by elderly individuals with cancer. We sought to quantify OOPE for community-dwelling individuals age 70 or older with: 1) no cancer (No CA), 2) a history of cancer, not undergoing current treatment (CA/No Tx), and 3) a history of cancer, undergoing current treatment (CA/Tx). Methods:  We used data from the 1995 Asset and Health Dynamics Study, a nationally representative survey of community-dwelling elderly individuals. Respondents identified their cancer status and reported OOPE for the prior 2 years for: 1) hospital and nursing home stays, 2) outpatient services, 3) home care, and 4) prescription medications. Using a multivariable two-part regression model to control for differences in sociodemographics, living situation, functional limitations, comorbid chronic conditions, and insurance coverage, the additional cancer-related OOPE were estimated. Results:  Of the 6370 respondents, 5382 (84%) reported No CA, 812 (13%) reported CA/No Tx, and 176 (3%) reported CA/Tx. The adjusted mean annual OOPE for the No CA, CA/No Tx, and CA/Tx groups were $1210,$1450, and $1880, respectively ( P  < .01). Prescription medications ($1120 per year) and home care services ($250) accounted for most of the additional OOPE associated with cancer treatment. Low-income individuals undergoing cancer treatment spent about 27% of their yearly income on OOPE compared to only 5% of yearly income for high-income individuals with no cancer history ( P  < .01). Conclusions:  Cancer treatment in older individuals results in significant OOPE, mainly for prescription medications and home care services. Economic evaluations and public policies aimed at cancer prevention and treatment should take note of the significant OOPE made by older Americans with cancer.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73612/1/j.1524-4733.2004.72334.x.pd

Blood Pressure and Cognitive Decline Over 8 Years in Middle-Aged and Older Black and White Americans

Although the association between high blood pressure (BP), particularly in midlife, and late-life dementia is known, less is known about variations by race and sex. In a prospective national study of 22 164 blacks and whites ≥45 years without baseline cognitive impairment or stroke from the REGARDS cohort study (Reasons for Geographic and Racial Differences in Stroke), enrolled 2003 to 2007 and followed through September 2015, we measured changes in cognition associated with baseline systolic and diastolic BP (SBP and DBP), as well as pulse pressure (PP) and mean arterial pressure, and we tested whether age, race, and sex modified the effects. Outcomes were global cognition (Six-Item Screener; primary outcome), new learning (Word List Learning), verbal memory (Word List Delayed Recall), and executive function (Animal Fluency Test). Median follow-up was 8.1 years. Significantly faster declines in global cognition were associated with higher SBP, lower DBP, and higher PP with increasing age ( P<0.001 for age×SBP×follow-up-time, age×DBP×follow-up-time, and age×PP×follow-up-time interaction). Declines in global cognition were not associated with mean arterial pressure after adjusting for PP. Blacks, compared with whites, had faster declines in global cognition associated with SBP ( P=0.02) and mean arterial pressure ( P=0.04). Men, compared with women, had faster declines in new learning associated with SBP ( P=0.04). BP was not associated with decline of verbal memory and executive function, after controlling for the effect of age on cognitive trajectories. Significantly faster declines in global cognition over 8 years were associated with higher SBP, lower DBP, and higher PP with increasing age. SBP-related cognitive declines were greater in blacks and men

Informal Caregiving for Diabetes and Diabetic Complications Among Elderly Americans

Objectives: Little is known regarding the amount of time spent by unpaid caregivers providing help to elderly individuals for disabilities associated with diabetes mellitus (DM). We sought to obtain nationally representative estimates of the time, and associated cost, of informal caregiving provided to the elderly with diabetes, and to determine the complications of DM that contribute most significantly to the subsequent need for informal care. Methods: We estimated multivariable regression models using data from the 1993 Asset and Health Dynamics (AHEAD) Study, a nationally representative survey of people aged 70 or older (N=7,443), to determine the weekly hours of informal caregiving and imputed cost of caregiver time for community-dwelling elderly with and without a diagnosis of DM. Results: Those without DM received an average of 6.1 hours per week of informal care, those with DM taking no medications received 10.5 hours, those with DM taking oral medications received 10.1 hours, and those with DM taking insulin received 14.4 hours of care (P

Vascular health, diabetes, APOE and dementia: the Aging, Demographics, and Memory Study.

INTRODUCTION: Evidence from clinical samples and geographically limited population studies suggests that vascular health, diabetes and apolipoprotein epsilon4 (APOE) are associated with dementia. METHODS: A population-based sample of 856 individuals aged 71 years or older from all contiguous regions of the United States received an extensive in-home clinical and neuropsychological assessment in 2001-2003. The relation of hypertension, diabetes, heart disease, stroke, medication usage, and APOE epsilon4 to dementia was modelled using adjusted multivariable logistic regression. RESULTS: Treated stroke (odds ratio [OR] 3.8, 95% confidence interval [CI] 2.0, 7.2), untreated stroke (OR 3.5, 95% CI 1.7, 7.3), and APOE epsilon4 (OR 2.8, 95% CI 1.7, 4.5) all increased the odds of dementia. Treated hypertension was associated with lower odds of dementia (OR 0.5, 95% CI 0.3, 1.0). Diabetes and heart disease were not significantly associated with dementia. A significant interaction was observed between APOE epsilon4 and stroke (P = 0.001). CONCLUSIONS: Data from the first dementia study that is representative of the United States population suggest that stroke, the APOE epsilon4 allele and their interaction are strongly associated with dementia.RIGHTS : This article is licensed under the BioMed Central licence at http://www.biomedcentral.com/about/license which is similar to the 'Creative Commons Attribution Licence'.

Cognitive health among older adults in the United States and in England

Abstract Background Cognitive function is a key determinant of independence and quality of life among older adults. Compared to adults in England, US adults have a greater prevalence of cardiovascular risk factors and disease that may lead to poorer cognitive function. We compared cognitive performance of older adults in the US and England, and sought to identify sociodemographic and medical factors associated with differences in cognitive function between the two countries. Methods Data were from the 2002 waves of the US Health and Retirement Study (HRS) (n = 8,299) and the English Longitudinal Study of Ageing (ELSA) (n = 5,276), nationally representative population-based studies designed to facilitate direct comparisons of health, wealth, and well-being. There were differences in the administration of the HRS and ELSA surveys, including use of both telephone and in-person administration of the HRS compared to only in-person administration of the ELSA, and a significantly higher response rate for the HRS (87% for the HRS vs. 67% for the ELSA). In each country, we assessed cognitive performance in non-hispanic whites aged 65 and over using the same tests of memory and orientation (0 to 24 point scale). Results US adults scored significantly better than English adults on the 24-point cognitive scale (unadjusted mean: 12.8 vs. 11.4, P < .001; age- and sex-adjusted: 13.2 vs. 11.7, P < .001).
