Project description:We determined the factors associated with exacerbation of heart failure, using a cohort (n = 192) nested within a randomized trial at a university-affiliated ambulatory practice. Factors associated with emergency or hospital care included left ventricular ejection fraction, hematocrit and serum sodium levels, refill adherence, and the ability to read a prescription label. Refill adherence of <40% was associated with a threefold higher incidence of hospitalization for heart failure than a refill adherence of >or=80% (P = 0.002). In multivariable analysis, prescription label reading skills were associated with a lower incidence of heart failure-specific emergency care (incidence rate ratio, 0.76; 95% confidence interval (CI), 0.19-0.69), and participants with adequate health literacy had a lower risk of hospitalization for heart failure (incidence rate ratio, 0.34; 95% CI, 0.15-0.76). We conclude that inadequate treatment adherence and health literacy skills are key factors in the exacerbation of heart failure. These findings emphasize the need for careful instruction of patients about their medications.

Project description:BACKGROUND:Frailty reflects decreased resilience to physiological stressors; its prevalence and prognosis are not fully defined in heart failure with preserved ejection fraction (HFpEF). METHODS:The Short Physical Performance Battery (SPPB) was prospectively obtained in 114 outpatients with HFpEF. The SPPB tests gait speed, tandem balance, and timed chair rises, each scored from 0 to 4 points. Severe and mild frailty were respectively defined as an SPPB score ?6 and 7-9 points. We used risk-adjusted logistic, Poisson, and negative binominal regression, respectively, to assess the relationship between SPPB score and risk of death or all-cause hospitalization, number of hospitalizations, and days hospitalized or dead longer than 6 months. RESULTS:Patients were similar to other HFpEF cohorts (age 68 ± 13 years, 58% female, body mass index 36 ± 8 kg/m2, multiple comorbidities). Mean SPPB score was 6.9 ± 3.2, and 80% of patients were at least mildly frail. Over a 6-month period, the SPPB score independently predicted death or all-cause hospitalization (odds ratio 0.81 per point, 95% confidence interval [CI] 0.69-0.94, P?=?.006), number of hospitalizations (incidence rate ratio 0.92 per point, 95% CI 0.86-0.97, P?=?.006), and days hospitalized or dead (incidence rate ratio 0.85 per point, 95% CI 0.73-0.99, P?=?.04). CONCLUSIONS:Lower extremity function, as measured by the SPPB, independently predicts hospitalization burden in outpatients with HFpEF. Additional studies are warranted to explore shared mechanisms and treatment implications of frailty in HFpEF.

Project description:ObjectivesThe level of health literacy is examined, as well as its conditioning factors in patients with heart failure who are seen routinely in a Primary Health Care Area.DesignA multicentre cross-sectional study.Setting10 Primary care centres from the metropolitan area of Barcelona.ParticipantsPatients diagnosed with heart failure.Inclusion criteriato have visited the Primary Health Care centre in the last year, being able to arrive at the primary care setting independently, and voluntarily participation.Main measurementsHealth Literacy Survey-European Union - Questionnaire (HLS-EU-Q) and Spanish version of the European Heart Failure Self-care Behaviour Scale. An analysis was made of the relationships between health literacy, self-care practices, sociodemographic, and clinical variables using ANOVA test and a multiple linear regression model.ResultsThe study included 318 patients (51.2% women) with a mean age of 77.9±8.7 years. The index of health literacy of 79.6% (n=253) of the participants indicated problems in understanding healthcare information. Health literacy level was explained by academic level (P<.001), the extent of heart failure (P=.032), self-care, and age (P<.04).The academic level explained 61.6% of the health of literacy (95% bootstrap: 44.58%; 46.75%).ConclusionsIn patients with stable heart failure, it is important to consider all factors that help patients to understand the healthcare information. Health literacy explains patient self-care attitude in heart failure.

Project description:BackgroundPatients hospitalized with heart failure are often readmitted. Health literacy may play a substantial role in the high rate of readmissions. The purpose of this study was to examine the association of health literacy with the composite end point of heart failure readmission rates and all-cause mortality in patients with heart failure living in rural areas.Methods and resultsRural adults (n = 575), hospitalized for heart failure within the past 6 months, completed the Short Test of Functional Health Literacy in Adults (STOFHLA) to measure health literacy and were followed for ≥2 years. The percentage of patients with the end point of heart failure readmission or all-cause death was different (P = .001) among the 3 STOFHLA score levels. Unadjusted analysis revealed that patients with inadequate and marginal health literacy were 1.94 (95% confidence interval [CI] 1.43-2.63; P < .001) times, and 1.91 (95% CI 1.36-2.67; P < .001) times, respectively, more likely to experience the outcome. After adjustment for covariates, health literacy remained a predictor of outcomes. Of the other covariates, worse functional class, higher comorbidity burden, and higher depression score predicted worse outcomes.ConclusionsInadequate or marginal health literacy is a risk factor for heart failure rehospitalization or all-cause mortality among rural patients with heart failure.

Project description:Adults with heart failure (HF) often demonstrate impairment across multiple domains of cognitive functioning and report poor health-related quality of life (HRQoL). Previous researchers have found that cognitive deficits were generally not associated with HRQoL in a carefully evaluated sample. The exception was memory, which was only weakly associated with HRQoL. However, cognitive deficits interfere with self-care and disease self-management, which could be expected to affect HRQoL.We sought to verify this counterintuitive finding in a large well-characterized sample of HF patients using a well-validated neuropsychological battery.Participants were 302 adults (63% male) predominately white (72.5%) HF patients (68.7 ± 9.6 years) recruited from 2 medical centers. Self-reported HRQoL was assessed using the Kansas City Cardiomyopathy Questionnaire. Participants completed a neuropsychological battery examining attention, executive function, memory, and visuospatial functioning. Hierarchical multiple linear regression was used for analyses.Mild global cognitive impairment was observed in 29.5% of the sample (Modified Mini-Mental State [3MS] Examination score <90). Controlling for gender, depression, HF severity, premorbid IQ, comorbidities, and education, only executive function predicted HRQoL, ? = .17, P < .05. However, executive function accounted for only 0.6% of the variance in HRQoL.Cognitive function generally did not predict HRQoL in HF patients. The correlates of HRQoL in HF do not appear to include mild cognitive impairment. Other factors may play a bigger role such as disease severity, age, and depressive symptoms. Future studies should investigate modifiable determinants of HRQoL in HF patients, toward the goal of finding interventions that preserve HRQoL during this chronic illness.

Project description:Patients with heart failure (HF) have high rates of cognitive impairment and depressive symptoms. Depressive symptoms have been associated with greater cognitive impairments in HF; however, it is not known whether particular clusters of depressive symptoms are more detrimental to cognition than others.The aim of this study was to identify whether somatic and/or nonsomatic depressive symptom clusters were associated with cognitive function in persons with HF.Participants were 326 HF patients (40.5% women, 26.7% non-white race-ethnicity, aged 68.6 ± 9.7 years). Depressive symptoms were measured using a depression questionnaire commonly used in medical populations: the Patient Health Questionnaire-9. Somatic and nonsomatic subscale scores were created using previous factor analytic results. A neuropsychological battery tested attention, executive function, and memory. Composites were created using averages of age-adjusted scaled scores. Regressions adjusting for demographic and clinical factors were conducted.Regressions revealed that Patient Health Questionnaire-9 total was associated with attention (? = -.14, P = .008) and executive function (? = -.17, P = .001). When analyzed separately, the nonsomatic subscale, but not the somatic symptoms subscale (P values ? .092), was associated with attention scores (? = -.15, P = .004) and memory (? = -.11, P = .044). Both nonsomatic (? = -.18, P < .001) and somatic (? = -.11, P = .048) symptoms were related to executive function. When included together, only the nonsomatic symptom cluster was associated with attention (? = -.15, P = .020) and executive function (? = -.19, P = .003).Greater overall depressive symptom severity was associated with poorer performance on multiple cognitive domains, an effect driven primarily by the nonsomatic symptoms of depression.These findings suggest that screening explicitly for nonsomatic depressive symptoms may be warranted and that the mechanisms underlying the depression-cognitive function relationship in HF are not solely related to sleep or appetite disturbance. Thus, interventions that target patients' somatic symptoms only (eg, poor appetite or fatigue) may not yield maximum cognitive benefit compared with a comprehensive treatment that targets depressed mood, anhedonia, and other nonsomatic symptoms.

Project description:BACKGROUND:Numeracy, health literacy, and cognition are important for chronic disease management. Prior studies have found them to be associated with poorer selfcare and worse clinical outcomes, but limited data exists in the context of heart failure (HF), a condition that requires patients to monitor their weight, fluid intake, and dietary salt, especially in the posthospitalization period. OBJECTIVE:To examine the relationship between numeracy, health literacy, and cognition with 30-day readmissions among patients hospitalized for acute decompensated HF (ADHF). DESIGN, SETTING, PATIENTS:The Vanderbilt Inpatient Cohort Study is a prospective longitudinal study of adults hospitalized with acute coronary syndromes and/or ADHF. We studied 883 adults hospitalized with ADHF. MEASUREMENTS:During their hospitalization, a baseline interview was performed in which demographic characteristics, numeracy, health literacy, and cognition were assessed. Through chart review, clinical characteristics were determined. The outcome of interest was 30-day readmission to any acute care hospital. To examine the association between numeracy, health literacy, cognition, and 30-day readmissions, multivariable Poisson (log-linear) regression was used. RESULTS:Of the 883 patients admitted for ADHF, 23.8% (n = 210) were readmitted within 30 days; 33.9% of the study population had inadequate numeracy skills, 24.6% had inadequate/marginal literacy skills, and 53% had any cognitive impairment. Numeracy and cognition were not associated with 30-day readmissions. Though (objective) health literacy was associated with 30-day readmissions in unadjusted analyses, it was not in adjusted analyses. CONCLUSIONS:Numeracy, health literacy, and cognition were not associated with 30-day readmission among this sample of patients hospitalized with ADHF.

Project description:BackgroundPrevious work has shown that there is a higher frequency of hospitalizations among black heart failure patients relative to white heart failure patients. We sought to determine whether racial differences exist in health literacy and access to outpatient medical care, and to identify factors associated with these differences.MethodsWe evaluated data from 1464 heart failure patients (644 black and 820 white). Health literacy was assessed using the Rapid Estimate of Adult Literacy in Medicine-Revised (ie, REALM-R), and access to care was assessed through participants' self-report.ResultsBlack race was strongly associated with worse health literacy and all measures of poor access to care in unadjusted analyses. After adjusting for demographics, noncardiac comorbidity, social support, insurance status, and socioeconomic status (income and education), the strongest associations were seen between race and: health literacy (OR 2.13, 95% CI 1.46 to 3.10), absence of a medical home (OR 1.76, 1.19-2.61), and cost as a deterrent to seeking health care (OR 1.55, 1.07 to 2.23).ConclusionsOur findings highlight that important racial differences in health literacy and access to care exist among patients with heart failure. These differences persist even after adjustment for a broad range of potential mediators, including educational attainment, income, and insurance status.

Project description:BackgroundLow health literacy is common among aging patients and is a risk factor for morbidity and mortality. We aimed to describe health literacy decline during aging and to investigate the roles of cognitive function and decline in determining health literacy decline.MethodsData were from 5,256 non-cognitively impaired adults aged ≥ 52 years in the English Longitudinal Study of Ageing. Health literacy was assessed using a four-item reading comprehension assessment of a fictitious medicine label, and cognitive function was assessed in a battery administered in-person at baseline (2004-2005) and at follow-up (2010-2011).ResultsOverall, 19.6% (1,032/5,256) of participants declined in health literacy score over the follow-up. Among adults aged ≥ 80 years at baseline, this proportion was 38.2% (102/267), compared to 14.8% (78/526) among adults aged 52-54 years (OR = 3.21; 95% CI: 2.26-4.57). Other sociodemographic predictors of health literacy decline were: male sex (OR = 1.20; 95% CI: 1.04-1.38), non-white ethnicity (OR = 2.42; 95% CI: 1.51-3.89), low educational attainment (OR = 1.58; 95% CI: 1.29-1.95 for no qualifications vs. degree education), and low occupational class (OR = 1.67; 95% CI: 1.39-2.01 for routine vs. managerial occupations). Higher baseline cognitive function scores protected against health literacy decline, while cognitive decline (yes vs. no) predicted decline in health literacy score (OR = 1.59; 95% CI: 1.35-1.87 for memory decline and OR = 1.56; 95% CI: 1.32-1.85 for executive function decline).ConclusionsHealth literacy decline appeared to increase with age, and was associated with even subtle cognitive decline in older non-impaired adults. Striking social inequalities were evident, whereby men and those from minority and deprived backgrounds were particularly vulnerable to literacy decline. Health practitioners must be able to recognize limited health literacy to ensure that clinical demands match the literacy skills of diverse patients.

Project description:ObjectivesThe purpose of this study was to determine if health literacy is associated with mortality, hospitalizations, or emergency department (ED) visits among patients living with heart failure (HF).BackgroundGrowing evidence suggests an association between health literacy and health-related outcomes in patients with HF.MethodsWe searched Embase, MEDLINE, PsycINFO, and EBSCO CINAHL from inception through January 1, 2019, with the help of a medical librarian. Eligible studies evaluated health literacy among patients with HF and assessed mortality, hospitalizations, and ED visits for all causes with no exclusion by time, geography, or language. Two reviewers independently selected studies, extracted data, and assessed the methodological quality of the identified studies.ResultsWe included 15 studies, 11 with an overall high methodological quality. Among the observational studies, an average of 24% of patients had inadequate or marginal health literacy. Inadequate health literacy was associated with higher unadjusted risk for mortality (risk ratio [RR]: 1.67; 95% confidence interval [CI]: 1.18 to 2.36), hospitalizations (RR: 1.19; 95% CI: 1.09 to 1.29), and ED visits (RR: 1.17; 95% CI: 1.03 to 1.32). When the adjusted measurements were combined, inadequate health literacy remained statistically associated with mortality (RR: 1.41; 95% CI: 1.06 to 1.88) and hospitalizations (RR: 1.12; 95% CI: 1.01 to 1.25). Among the 4 interventional studies, 2 effectively improved outcomes among patients with inadequate health literacy.ConclusionsIn this study, the estimated prevalence of inadequate health literacy was high, and inadequate health literacy was associated with increased risk of death and hospitalizations. These findings have important clinical and public health implications and warrant measurement of health literacy and deployment of interventions to improve outcomes.
