The association between congestive heart failure and cognitive performance in a primary care population of elderly adults: the Steel Valley Seniors Survey.

BACKGROUND: Evidence suggests an association between congestive heart failure (CHF) and cognitive function, particularly in heart transplant patients and patients hospitalized for CHF. We examined the association between CHF and cognitive performance in stable outpatients recruited from primary care. METHODS: This is a cross-sectional secondary data analysis of the Steel Valley Seniors Survey, an epidemiological study of elderly primary care outpatients. Participants aged >/= 65 years were recruited in primary care clinics. The study cohort (n = 354) is a subgroup, composed of subjects with Mini-mental State Examination score < 25, and a random sample of the remaining, who underwent a baseline assessment in the home. The assessment included demographics, comorbid illnesses, depressive symptoms, functional status, a neurological examination and a neuropsychological battery. CHF is defined by self-report and/or chart review, and stable CHF as not being hospitalized in the year prior to the assessment. The associations between CHF and specific cognitive tests were examined by bivariate analysis and logistic regression, controlling for demographic variables. RESULTS: Subjects with CHF performed worse on tests of visual memory [10.1 (S.D. 5.4) vs. 12.7 (S.D. 5.2), p = 0.007], Trailmaking B [0.1 (0.1) vs. 0.2 (0.1), p = 0.002], category fluency [11.1 (4.4) vs. 13.4 (4.5), p = 0.008], and clock drawing [5.6 (1.9) vs. 6.7 (1.4), p < 0.001] compared to subjects without CHF, after adjustment for relevant demographic variables. CONCLUSION: CHF is associated with lower cognitive functioning in a population of patients with stable heart failure in primary care settings.

Discrepancies in information provided to primary care physicians by patients with and without dementia: the Steel Valley Seniors Survey.

OBJECTIVE: The objective of this study was to examine associations between discrepancies in health information provided to primary care providers and severity of impairment in older patients with and without dementia. METHODS: This study included brief assessment and medical record review of 1,107 patients with a mean (standard deviation) age of 76.3 (6.6) years (range: 65-100 years) in seven small-town primary care practices. In 358 patients, detailed in-home assessment included demographics; dementia by Clinical Dementia Rating (CDR) scale; and frequencies of memory complaints, falls, and inadvertent medication nonadherence determined from medical records and standardized in-home research assessments. Main outcome variables were trends in discrepancies between chart reviews and research assessments. Main explanatory variable was CDR box total scores. RESULTS: Proportions of patients reporting memory complaints and falls, and evidence of inadvertent nonadherence, in the charts and by research assessment increased with CDR. Discrepancies between medical record and research assessment, were also associated with CDR, showing linear trends for memory complaints and inadvertent nonadherence and a quadratic trend for falls. CONCLUSION: Memory complaints, falls, and inadvertent medication nonadherence increase with dementia severity. The levels of discrepancy between information patients provided to their physicians and information they provided in response to detailed, standardized assessments, also varied with dementia severity. Physicians should be alert to the possibility of receiving unreliable health information from even mildly demented patients, whether or not dementia has been detected.

Gambling participation and social support among older adults: a longitudinal community study.

The purpose of this preliminary study was to examine associations between leaving home to engage in bingo or gambling activity and indices of physical and mental health and social support among a representative community cohort of 1016 elderly people. Cross-sectional and longitudinal data gathered from a prospective epidemiological study in a rural, low socio-economic status, area of Pennsylvania was employed. The cohort had a mean age of 78.8 (SD = 5.1) (range 71-97) and participated in three consecutive biennial "waves" of data collection. Nearly half (47.7) of the cohort reported gambling. To predict gambling, the independent variables included age, sex, education, employment, social support, depressive symptoms, self-rated health, alcohol use, cigarette use, and cognitive functioning. In cross-sectional, univariate analyses, gambling was associated with younger age, sex (male), fewer years of education, greater social support, lower depression scores, better self-rated health, alcohol use in the past year, and higher cognitive functioning. In a cross-sectional multiple regression model, younger age, greater social support, and alcohol use in the past year remain strongly and independently associated with gambling activity. Longitudinally, age, sex, social support, alcohol use, and gambling are predictive of future gambling activity. The results revealed that gambling may offer a forum of social support to older adults who are often isolated as they age.
