BACKGROUND: Although guidelines recommend focusing primarily on stroke risk to recommend anticoagulants in atrial fibrillation (AF), physicians report that geriatric syndromes (e.g., falls and disability) are important when considering anticoagulants. Little is known about the prevalence of geriatric syndromes in older adults with AF or the association with anticoagulant use.

METHODS: We performed a cross-sectional analysis of the 2014 Health and Retirement Study, a nationally representative study of older Americans. Participants were asked questions to assess domains of aging, including function, cognition, and medical conditions. We included participants 65 years and older with 2 years of continuous Medicare enrollment who met AF diagnosis criteria by claims codes. We examined five geriatric syndromes: one or more falls within the last 2 years, receiving help with activities of daily living (ADLs) or instrumental ADLs (IADL), experienced incontinence, and cognitive impairment. We determined the prevalence of geriatric syndromes and their association with anticoagulant use, adjusting for ischemic stroke risk (i.e., CHA DS -VASc score [congestive heart failure, hypertension, age, diabetes mellitus, stroke, vascular disease, and sex]).

RESULTS: In this study of 779 participants with AF (median age = 80 years; median CHA DS -VASc score = 4), 82% had one or more geriatric syndromes. Geriatric syndromes were common: 49% reported falls, 38% had ADL impairments, 42% had IADL impairments, 37% had cognitive impairments, and 43% reported incontinence. Overall, 65% reported anticoagulant use; guidelines recommend anticoagulant use for 97% of participants. Anticoagulant use rate decreased for each additional geriatric syndrome (average marginal effect = -3.7%; 95% confidence interval = -1.4% to -5.9%). Lower rates of anticoagulant use were reported in participants with ADL dependency, IADL dependency, and dementia.

CONCLUSION: Most older adults with AF had at least one geriatric syndrome, and geriatric syndromes were associated with reduced anticoagulant use. The high prevalence of geriatric syndromes may explain the lower than expected anticoagulant use in older adults.

There are few long-term data on the loss of function following ECH. This study’s goal was to measure the acute and persistent loss of independence in activities of daily living (ADLs) after ECH hospitalization. Methods: We used data from 1995-2015 from the Health and Retirement Study, a longitudinal, nationally representative survey of older Americans. We included subjects over age 65 who consented to Medicare linkage. We examined the association of ECH hospitalization with ability to perform all ADLs independently (walk across a room, dress, bathe, eat, toilet, get out of bed). To compare rates of ADL independence over time between those with ECH and a control group without ECH, we fit a logistic regression model that included an interaction term between ECH hospitalization and time and adjusted for comorbidities and sociodemographics. Results: In a cohort of 8950 with an average follow-up time of 7.3 years (65,335 person-years), 882 (10%) participants were hospitalized for ECH. Mean age was 78, and 59% were women. In the control group without ECH, the baseline rate of ADL independence declined by an average of 3.1% per year (average marginal effect [AME], 95% CI -3.1% to -3.3%). Assuming hospitalization for ECH at 5.2 years, the median time to ECH in this cohort, ECH was associated with an immediate decrease in ADL independence from 68% to 53% (AME -15%, 95% CI -11% to -18%). Following ECH, the average annual baseline rate of function loss did not change. Conclusions: In this nationally representative cohort, ECH hospitalization was associated with an immediate and pronounced decline in function that was equivalent to accelerating ADL disability by 5 years. After ECH, ADL independence continued to decline and did not recover to pre-ECH levels of independence over time. %B Circulation %V 144 %P A10778 %G eng %N Suppl _1 %R 10.1161/circ.144.suppl_1.10778 %0 Journal Article %J JAMA Surgery %D 2020 %T Association of Functional, Cognitive, and Psychological Measures With 1-Year Mortality in Patients Undergoing Major Surgery %A Victoria L.

Although measures, such as functional, cognitive, and psychological status, are known to be crucial components of health in older persons, they are not often used in assessing the risk of adverse postoperative outcomes in older adults.To determine the association between measures of physical, cognitive, and psychological function and 1-year mortality in older adults after major surgery.Retrospective analysis of a prospective cohort study of participants 66 years or older who were enrolled in the nationally representative Health and Retirement Study and underwent 1 of 3 types of major surgery.Major surgery, including abdominal aortic aneurysm repair, coronary artery bypass graft, and colectomy.Our outcome was mortality within 1 year of major surgery. Our primary associated factors included functional, cognitive, and psychological factors: dependence in activities of daily living (ADL), dependence in instrumental ADL, inability to walk several blocks, cognitive status, and presence of depression. We adjusted for other demographic and clinical predictors.Of 1341 participants, the mean (SD) participant age was 76 (6) years, 737 (55\%) were women, 99 (7\%) underwent abdominal aortic aneurysm repair, 686 (51\%) coronary artery bypass graft, and 556 (42\%) colectomy; 223 (17\%) died within 1 year of their operation. After adjusting for age, comorbidity burden, surgical type, sex, race/ethnicity, wealth, income, and education, the following measures were significantly associated with 1-year mortality: more than 1 ADL dependence (29\% vs 13\%; adjusted hazard ratio [aHR], 2.76; P = .001), more than 1 instrumental ADL dependence (21\% vs 14\%; aHR, 1.32; P = .05), the inability to walk several blocks (17\% vs 11\%; aHR, 1.64; P = .01), dementia (21\% vs 12\%; aHR, 1.91; P = .03), and depression (19\% vs 12\%; aHR, 1.72; P = .01). The risk of 1-year mortality increased within the increasing risk factors present (0 factors: 10.0\%; 1 factor: 16.2\%; 2 factors: 27.8\%).In this older adult cohort, 223 participants (17\%) who underwent major surgery died within 1 year and poor function, cognition, and psychological well-being were significantly associated with mortality. Measures in function, cognition, and psychological well-being need to be incorporated into the preoperative assessment to enhance surgical decision-making and patient counseling. %B JAMA Surgery %G eng %U https://jamanetwork.com/journals/jamasurgery/article-abstract/2762522 %9 Journal %R 10.1001/jamasurg.2020.0091
