Correlates of health literacy in patients with chronic heart failure

Neuropsychological and Health Literacy Correlates of Science Knowledge Among Older and Younger Healthy Adults

Science knowledge refers to the depth and breadth of facts acquired within the life, social, and earth sciences, and it has implications for both public and personal health. Drawing from cognitive aging theory, we examine whether levels of science knowledge are associated with age, neuropsychological functioning, and personal health literacy. Fifty-two younger and fifty older healthy adults completed our telephone-based study that included a commonly used test of science knowledge, as well as measures of neuropsychological functioning, health literacy, and relevant descriptives (e.g., mood). Adjusting for other demographics and neuropsychological functioning, older adults had significantly lower science knowledge test scores than younger adults. In the full sample, lower science knowledge showed medium-to-large associations with episodic memory, executive functions, and health literacy, independent of years of education. These results suggest that older adults' science knowledge falls slightly below that of their younger counterparts and is independently associated with higher order neuropsychological functions and aspects of personal health, which may have implications for accessing, understanding, and using relevant public health information across the lifespan.

Health literacy is associated with cognition and everyday functioning in a consecutive clinical series of people with epilepsy in a surgical setting

OBJECTIVE

Low health literacy is common among people with epilepsy (PWE) and may play an important role in disease management and outcomes. The current study evaluated whether health literacy is related to cognition, health, and everyday functioning in PWE.

METHODS

This cross-sectional, correlational study included 25 demographically comparable healthy adults retrospectively matched to a consecutive series of 89 PWE presenting for neuropsychological evaluation in a surgical setting and who completed the Newest Vital Sign and Brief Health Literacy Screener. The PWE also completed a comprehensive neuropsychological battery and measures of quality of life and everyday functioning.

RESULTS

PWE had significantly lower health literacy as compared to healthy adults (ps < 0.05) at a medium-to-large effect size. In analyses covarying for education and oral word reading literacy in the PWE sample, lower health literacy was independently associated with bilateral seizure onsets, greater antiseizure medication burden, poorer performance on measures of memory and information processing speed, and difficulties with self-care (ps < 0.05).

SIGNIFICANCE

Findings suggest that PWE are at risk for low health literacy, which may be partly attributable to disrupted brain-behavior relationships and contribute to poorer everyday functioning. Future studies are needed to identify effective methods to support and improve health literacy in PWE.

Validation of three health literacy screening questions compared with S-TOFHLA in a low-income diverse English- and Spanish-Speaking population

BACKGROUND

Clinicians need a tool to gauge patients' ability to understand health conditions and treatment options. The Short-form Test of Functional Health Literacy in Adults (S-TOFHLA) is the gold standard for this, but its length is prohibitive for use in clinical settings. This study seeks to validate a novel three-item question set for predicting health literacy.

METHODS

This cross-sectional study utilized an in-person questionnaire alongside the S-TOFHLA. The sample included 2027 English- and Spanish-speaking adults (≥18 years) recruited from primary care practices serving a low-income eastern Pennsylvania community. Most patients (57.7%) identified as Hispanic. Diagnostic accuracy of each question and aggregated scores were assessed against the validated survey by calculating the area under the receiver operating characteristic (AUROC) curve.

RESULTS

Questions in the 'Problems Learning' and 'Help Reading' domains (AUROC 0.66 for each) performed better than the 'Confident Forms' question (AUROC 0.64). Summing all three scores resulted in an even higher AUROC curve (0.71). Cronbach's alpha of the combined items was 0.696.

CONCLUSIONS

Study results suggest that any of the three questions are viable options for screening health literacy levels of diverse patients in primary care clinical settings. However, they perform better as a summed score than when used individually.

Relationship between People's Interest in Medication Adherence, Health Literacy, and Self-Care: An Infodemiological Analysis in the Pre- and Post-COVID-19 Era

The prevalence of non-communicable diseases has risen sharply in recent years, particularly among older individuals who require complex drug regimens. Patients are increasingly required to manage their health through medication adherence and self-care, but about 50% of patients struggle to adhere to prescribed treatments. This study explored the relationship between interest in medication adherence, health literacy, and self-care and how it changed during the COVID-19 pandemic. We used Google Trends to measure relative search volumes (RSVs) for these three topics from 2012 to 2022. We found that interest in self-care increased the most over time, followed by health literacy and medication adherence. Direct correlations emerged between RSVs for medication adherence and health literacy (r = 0.674, p < 0.0001), medication adherence and self-care (r = 0.466, p < 0.0001), and health literacy and self-care (r = 0.545, p < 0.0001). After the COVID-19 pandemic outbreak, interest in self-care significantly increased, and Latin countries showed a greater interest in self-care than other geographical areas. This study suggests that people are increasingly interested in managing their health, especially in the context of the recent pandemic, and that infodemiology may provide interesting information about the attitudes of the population toward chronic disease management.

Challenges in implementation of patient-centred care in cardiac care unit: A qualitative study

AIM

This study aimed to explore the barriers to the implementation of patient-centred care (PCC) in the cardiac care unit (CCU) from the perspectives of patients, nurses, physicians and nursing managers.

DESIGN

This study was performed with a descriptive qualitative study approach.

METHODS

In this study, the data were collected through face-to-face in-depth semi-structured interviews with 10 cardiac care nurses, one assistant nurse, two cardiologists, seven patients admitted to the CCU and nine nursing managers and analysed by Graneheim and Lundman content analysis method.

RESULTS

After analysing the data, eight subcategories and three main categories were extracted. The main categories included challenges related to: organization, healthcare providers and patients. This study demonstrated the barriers to the implementation of PCC in the CCU. Insights into these barriers can guide interventions aimed at improving the quality of PCC in the CCU, which in turn can lead to improved disease outcomes.

Exploring Health Literacy Categories in Patients With Heart Failure: A Latent Class Analysis

BACKGROUND

Although a growing number of studies have demonstrated that patients' health literacy is associated with health outcomes, the exact relationship between them is not clear.

AIMS AND OBJECTIVES

The aim of this study was to explore latent classes of health literacy in patients with heart failure and analyze the differences among different groups.

DESIGN AND METHODS

This is a cross-sectional survey. Patients diagnosed with heart failure were selected from 3 tertiary hospitals in Tianjin, China, from March 2019 to November 2019. We measured patients' health literacy using the Health Literacy Scale for Chronic Patients. Latent class analysis was carried out based on the patients' Health Literacy Scale for Chronic Patients scores. Multinomial logistic regression was used to identify the predictive indicators of the latent classes.

RESULTS

The health literacy of patients with heart failure was divided into 3 different latent classes, named "high health literacy group," "low literacy high dependence group," and "moderate literacy high willingness group." There were statistically significant differences in gender, age, smoking history, marital status, education level, household income level, and quality of life among different health literacy classes. Low education level and household income level predicted poor health literacy.

CONCLUSION

There were 3 latent classes for the health literacy of patients with heart failure. Different health literacy classes exhibited their own distinctive characteristics. Patients in the "moderate literacy high willingness group" had the worst quality of life. Understanding the specific types of health literacy in patients with heart failure facilitates targeted nursing interventions to improve their quality of life.

Do Health Information Sources Influence Health Literacy among Older Adults: A Cross-Sectional Study in the Urban Areas of Western China

BACKGROUND

Previous studies have found that the dissemination pattern and delivery mechanism of information can provide crucial resources and empowerment for individuals to the promotion of health literacy. The present study investigates how health information sources are associated with health literacy among older adults in west China, and tries to explain the mechanisms underlying the link between health information sources and health literacy in the Chinese context.

METHODS

The cross-sectional study employed a representative sample of 812 urban citizens aged 60 and older in 2017 in Western China.

RESULTS

We found that health information sources including healthcare practitioners (B = 4.577, p < 0.001), neighbors (B = 2.545, p < 0.05), newspapers (B = 4.280, p < 0.001), and television (B = 4.638, p < 0.001) were positively associated with health literacy. Additionally, age (B = -1.781, p < 0.001) was negatively associated with health literacy, and the socio-economic status factors including minority (B = -10.005, p < 0.001), financial strain status of perceived very difficult (B = -10.537, p < 0.001), primary school (B = 11.461, p < 0.001), junior high school (B = 18.016, p < 0.001), polytechnic school or senior high school (B = 21.905, p < 0.001), college and above (B = 23.433, p < 0.001) were significantly linked to health literacy, and suffering from chronic diseases (B = 3.430, p < 0.01) was also positively related to health literacy.

CONCLUSIONS

Health information sources including healthcare practitioners, neighbors, newspapers, and television have a strong influence on health literacy, which implies that the four main types of sources are the important patterns of health information dissemination in the reinforcement of health literacy. In addition, the present findings also indicate age, minority and disease differences in health literacy and confirm the influence of enabling factors including educational attainment and financial strain on health literacy. Based on these findings and their implications, specific evidence is presented for the reinforcement of health literacy in interpersonal and mass communication, and in the educational and financial settings in the Chinese context. The present results also suggest that the age-specific, minority-specific and disease-specific measures should be taken to promote health literacy among older adults.

Health Literacy of Newly-Admitted Cancer Patients in Vietnam: Difficulties Understanding Treatment Options and Processing Health-Related Information

Having a good understanding of cancer patients' health literacy in the early stage of diagnosis can help to implement strategies to improve the management process and overall health outcomes. The study aims to describe health literacy and its association with socio-demographic characteristics among newly admitted cancer patients. A cross-sectional study was conducted on 262 newly admitted patients of a cancer hospital in Vietnam using the Vietnamese version of the HLS-SF12 questionnaire. Descriptive analytics and regression analysis were used to describe health literacy and examine associated factors. Older age, lower level of education, and living in rural areas were associated with lower health literacy while there was no significant relationship between gender and health literacy among newly admitted cancer patients. Many newly admitted patients, especially the older patients have difficulties understanding the different treatment options (54%) and evaluating the reliability of health information on the internet (43%). During the early stage of treatment, strategies should be implemented with regards to patients' health literacy, to properly educate patients and their caregivers to improve communication, adherence to medication, lifestyle, and overall better quality of life and treatment outcome.

Knowledge About COVID-19 Symptoms, Transmission, and Prevention: The Relationship With Cognitive Status in Older Adults

Objective: Advanced age poses an increased risk for cognitive impairment, and therefore, poor knowledge regarding the risks associated with COVID-19 may confer vulnerability. We administered a COVID-19 Knowledge Questionnaire to older persons to evaluate the association between knowledge regarding public health recommendations, and cognitive status as measured by the Montreal Cognitive Assessment (MoCA). Method: Ninety-nine participants completed a 22-item questionnaire about COVID-19 symptoms, risks, and protective strategies, and they also completed the MoCA. Associations between knowledge and cognitive status were examined via Spearman correlations. Results: The mean (SD) age of participants was 72.6 (7.6) years, and MoCA scores averaged 23.4 (4.5) points. Higher MoCA total scores were significantly (p < .001) correlated with a greater number of correct questionnaire responses. Higher Orientation and Memory Index scores were moderately associated with an increased number of correct responses (p < .001), with the Executive Index exhibiting a significant albeit weaker association. MoCA Index scores assessing attention, language, and visuospatial functioning were not significantly associated with COVID-19 knowledge. Conclusions: Given the rapid transmission rate of the SARS CoV-2 infections, COVID knowledge lapses will likely have deleterious repercussions. Public health messages should ensure effective acquisition and retention of COVID specific information, especially in cognitively compromised older adults.

Literacy critical to heart failure management: a scoping review

Heart failure is a complex clinical syndrome most commonly encountered among older adults. This complex clinical syndrome is associated with poor health outcomes such as frequent admissions and mortality. These adverse outcomes are commonly associated with poor self-care and lower health literacy. Literacy is a combination of knowledge and skills and often reflected by appropriate interaction with the community, while health literacy is the cognitive and social skills reflected by accessing and comprehending health information and making appropriate health decisions. These decisions are common and challenging to patients with heart failure. Poor outcomes are said to be reduced by adequate self-care, which is associated with health literacy among heart failure patients. Better self-care was also shown to be associated with self-efficacy and self-confidence that were in turn associated with health literacy. Hence, enhancing health literacy among patient with heart failure is critical to enable them to increase control over their disease by better understanding and participating in health care, while being empowered to take part in designing health care services and even tailoring research to serve their needs and consequently improve outcome at the individual and community level. In clinical practice, assessing health literacy, measuring health literacy, and identifying patients at risk of low nutrition literacy is important to enhance health literacy and health outcomes. Hence, developing reliable and valid methods and tools for assessment and developing tailored and targeted interventions is of critical importance.

Aging and Functional Health Literacy: A Population-based Study

OBJECTIVES

To investigate functional health literacy and its associated factors among older adults drawn from a disadvantaged area.

DESIGN

Cross-sectional epidemiologic study.

SETTING

Population-based cohort randomly selected from the voter registration lists.

PARTICIPANTS

Individuals aged 65+ (N=1066).

MEASUREMENTS

The Short Test of Functional Health Literacy in Adults (S-TOFHLA); demographics; self-rated health; number of prescription drugs; modified Center for Epidemiologic Studies- Depression scale; Mini-Mental State Examination; Wechsler Test of Adult Reading; Clinical Dementia Rating; cognitive domain composite scores; independence in Instrumental Activities of Daily Living and medication management; health services utilization (emergency/urgent care visits and hospitalizations).

RESULTS

Low (inadequate or marginal) S-TOFHLA scores were obtained by 7.04% of the sample. In unadjusted analyses, participants with low S-TOFHLA scores were significantly more likely than those with higher scores to be older, male, non-White, with lesser education and lower household income, to have lower scores on the Wechsler Test of Adult Reading, the Mini-Mental State Examination, and all cognitive domains; to be more dependent in Instrumental Activities of Daily Living and be taking more prescription drugs. In a multiple regression model including all covariates, only older age, male sex, and lower reading level were independently associated with inadequate or marginal S-TOFHLA scores.

CONCLUSION

In a population-based sample of older adults, low functional health literacy was associated with age, sex, education, and reading ability. Basic functional health literacy is essential for understanding health information and instructions. Clinicians should formally or informally assess health literacy in their older patients to ensure effective communication and enhance health outcomes.

Far from black and white: Role of race, health literacy, and socioeconomic factors in the presentation of acute diverticulitis

BACKGROUND

Racial discrepancies in treatment and outcomes of acute diverticulitis have been observed, yet underlying factors are poorly understood. We aimed to identify racial inequalities in health literacy among patients hospitalized with acute diverticulitis and characterize factors associated with more severe presentation.

METHODS

We performed retrospective cohort analysis of 947 Black or White patients admitted with acute diverticulitis at a quaternary referral center from January 2009 through September 2019. Health literacy was determined by the validated Brief Health Literacy Screening, and socioeconomic status was defined by area deprivation index, a composite of multiple neighborhood socioeconomic deprivation measures. The primary outcome was severity of disease presentation represented by systemic inflammatory response syndrome criteria; secondary outcomes included intensive care unit admission, length of stay, and invasive interventions.

RESULTS

Among all study participants, 121 (12.8%) self-identified as Black. Overall, 140 (14.8%) patients had inadequate health literacy, and 495 (52.3%) had area deprivation index greater than the national median. There was no association between race or area deprivation index and health literacy. A total of 340 (35.9%) patients met criteria for systemic inflammatory response syndrome, and 88 (9.3%) underwent an intervention; median length of stay was 3.5 days. Race, health literacy, and area deprivation index were not significantly associated with outcomes (P > .05).

CONCLUSION

Among patients with acute diverticulitis, no difference in severity of presentation by race, health literacy, or area deprivation index was observed. These findings suggest that differences in presentation of acute diverticulitis may not be driven by these social factors. Future studies should include considerations of clinical characteristics of acute diverticulitis, such as the role of access and underuse of healthcare resources.

The influence of gender and race on heart failure self-care

OBJECTIVES

To explore gender and racial differences in heart failure (HF) self-care processes and examine whether gender and race predict HF self-care.

METHODS

A secondary analysis of baseline data (n = 107) from a longitudinal HF study (54.2% males; 56% non-Caucasians) was conducted. The self-care of heart failure index was used to measure self-care maintenance, management, and confidence. Descriptive statistics and univariate analyses examined gender and racial differences in HF self-care outcomes. Multiple linear regression examined whether gender and race predicted HF self-care maintenance, management, and confidence.

RESULTS

Univariate analyses indicated that Caucasians reported significantly better self-care maintenance (p = 0.042), while non-Caucasians reported significantly better self-care management (p = 0.003). Males had significantly higher self-care confidence scores versus women (p = 0.017). Multiple regression analysis indicated Caucasian race predicted significantly worse self-care management (β = -11.188; p = 0.006) versus non-Caucasian, while male gender predicted significantly higher self-care confidence scores (β = 7.592; p = 0.010) versus female gender. Gender nor race significantly predicted self-care maintenance.

DISCUSSION

Although gender and race may influence HF self-care, other factors may be more important. More research is needed to identify individual factors that contribute to HF self-care to improve education and intervention.

Validation of a Short Form for Health Literacy Assessment Using Talking Touchscreen Technology

BACKGROUND

Health literacy is an area of growing research and clinical interest, necessitating short, accurate measures of this complex construct. Health Literacy Assessment Using Talking Touchscreen Technology (Health LiTT) measures prose, document, and quantitative literacy by self-administration on a touchscreen computer.

OBJECTIVE

The objective of this study was to assess the validity of a short form of Health LiTT and to identify a meaningful cutoff score for adequate health literacy.

METHODS

A subsample of 137 participants from the Literacy and Cognitive Function among Older Adults study completed a 10-item Health LiTT short form and three interviewer-administered health literacy measures: Test of Functional Health Literacy in Adults (TOFHLA), Rapid Estimate of Adult Literacy in Medicine (REALM), and Newest Vital Sign (NVS). Convergent validity was assessed by correlating scores for all measures, and known-groups validity was assessed by comparing mean Health LITT scores across TOFHLA levels (inadequate, marginal, adequate). Internal consistency reliability was estimated with Cronbach's alpha. A cutoff score for adequate health literacy was established using the TOFHLA cutoff for adequate versus inadequate/marginal health literacy.

KEY RESULTS

Spearman correlations between Health LiTT scores and total TOFHLA, REALM, and NVS scores were 0.65, 0.69, and 0.56, respectively (all p < .001). Mean Health LiTT scores were significantly and meaningfully different across inadequate (40.4), marginal (50.1), and adequate (57.1) TOFHLA categories (F = 60.6; p < .001). Cronbach's alpha for the Health LiTT short form was .73. A cutoff score of 55 on Health LiTT showed acceptable sensitivity and specificity to identify adequate health literacy.

CONCLUSIONS

This 10-item Health LiTT short form demonstrated excellent convergent and known-groups validity and acceptable internal consistency reliability in older adults. The established cutoff also showed excellent sensitivity and specificity. Validation of other custom Health LiTT short forms with varying items from the bank and computer adaptive test-generated Health LiTT scores is ongoing. [HLRP: Health Literacy Research and Practice. 2020;4(4):e200-e207.] PLAIN LANGUAGE SUMMARY: This article provides evidence of the need for and psychometric properties of a valid and reliable short form of the flexible, technologically advanced Health Literacy Assessment Using Talking Touchscreen Technology measure, as well as a cutoff score to note adequate versus marginal/inadequate health literacy.

The role of health literacy, depression, disease knowledge, and self-efficacy in self-care among adults with heart failure: An updated model

BACKGROUND

Patients with inadequate health literacy and heart failure face high healthcare costs, more hospitalizations, and greater mortality. To address these negative consequences, patients need to improve heart failure self-care. Multiple factors may influence self-care, but the exact model by which they do so is not fully understood.

OBJECTIVES

The objective of this study was to examine a model exploring the contribution of health literacy, depression, disease knowledge, and self-efficacy to the performance of heart failure self-care.

METHODS

Using a cross-sectional design, patients were recruited from a heart failure clinic and completed validated assessments of their cognition, health literacy, depression, knowledge, self-efficacy and self-care. Patients were separated into two groups according to their health literacy level: inadequate/marginal and adequate. Differences between groups were assessed with an independent t-test. Hypothesized paths and mediated relationships were estimated and tested using observed variable path analysis.

RESULTS

Participants (n = 100) were mainly male (67%), white (93%), and at least had a high school education (85%). Health literacy was associated with disease knowledge (path coefficient=0.346, p = 0.002), depression was negatively associated with self-efficacy (path coefficient=-0.211, p = 0.037), self-efficacy was positively associated with self-care (path coefficient=0.402, p<0.0005), and there was evidence that self-efficacy mediated the link between depression and self-care. There was no evidence of: mediation of the link between health literacy and self-care by knowledge or self-efficacy; positive associations between knowledge and self-efficacy or self-care; or mediation of the disease knowledge and self-care relationship by self-efficacy. Further, depression was associated with self-care indirectly rather than also directly as hypothesized.

CONCLUSIONS

Self-efficacy and depression are associated with heart failure self-care. Data generated from the model suggest that healthcare professionals should actively engage all patients to gain self-efficacy and address depression to positively affect heart failure self-care.

Addressing Social Determinants of Health in the Care of Patients With Heart Failure: A Scientific Statement From the American Heart Association

Heart failure is a clinical syndrome that affects >6.5 million Americans, with an estimated 550 000 new cases diagnosed each year. The complexity of heart failure management is compounded by the number of patients who experience adverse downstream effects of the social determinants of health (SDOH). These patients are less able to access care and more likely to experience poor heart failure outcomes over time. Many patients face additional challenges associated with the cost of complex, chronic illness management and must make difficult decisions about their own health, particularly when the costs of medications and healthcare appointments are at odds with basic food and housing needs. This scientific statement summarizes the SDOH and the current state of knowledge important to understanding their impact on patients with heart failure. Specifically, this document includes a definition of SDOH, provider competencies, and SDOH assessment tools and addresses the following questions: (1) What models or frameworks guide healthcare providers to address SDOH? (2) What are the SDOH affecting the delivery of care and the interventions addressing them that affect the care and outcomes of patients with heart failure? (3) What are the opportunities for healthcare providers to address the SDOH affecting the care of patients with heart failure? We also include a case study ( Data Supplement ) that highlights an interprofessional team effort to address and mitigate the effects of SDOH in an underserved patient with heart failure.

Peculiarities of health literacy in people with mental disorders: A cross-sectional study

BACKGROUND

Health literacy (HL) is considered a key concept to positively address relevant decisions concerning physical and mental health. According to an integrated model of a European Consortium, the process to access, understand, appraise and apply health information is at the centre of practising HL.

AIM

In this study, we examine HL in a population with an early onset of a mental disorder (MD).

METHODS

Results are based on a cross-sectional survey among people with MD (n = 310) who sought help at an early detection centre for MD in Cologne, Dresden or Munich. Help-seekers filled out the European Health Literacy Survey questionnaire (HLS-EU-Q) on perception-based HL, socio-demographic data and general health status. Psychopathology was assessed separately by trained specialists. Data are compared with a representative sample of the German population.

RESULTS

Overall, HL was lower in a sample with MD compared with the general population. Disease-specific limitations were present in accessing, appraising and applying health information, whereas understanding was perceived fairly easy. Statistical analysis of limited HL revealed correlations with the diagnosis of affective disorders and anxiety disorders, an increase of depressive symptoms as well as the presence of more than one MD. In line with these findings, low levels of HL were associated with a worse general health status.

CONCLUSION

In a population with MD, accessing, appraising and applying health information seemed to be particularly challenging. Therefore, educational programmes that mainly focus on increasing knowledge might not be sufficient for improving the HL in people with MD. Further research should concentrate on context-specific HL to foster behavioural change and improve overall health.

Cognitive Function in Cardiac Patients: Exploring the Occupational Therapy Role in Lifestyle Medicine

Patients with cardiac dysfunction are at increased risk of mild cognitive impairment, which can affect their ability to successfully engage in daily activities important for home and community safety and in maintaining health and well-being. This risk increases in accordance with the number of cardiac conditions and cardiovascular risk factors or comorbidities. Occupational therapy has a role in chronic disease management in assessing and improving functional abilities affected by physical, emotional, and cognitive domains. With a holistic and client-centered approach, occupational therapy can complement lifestyle medicine principles through promotion and enablement of engagement in purposeful activity and self-management practices. It is suggested that the clinical management of patients with cardiac dysfunction expands beyond the traditional physical aspects of care to encompass cognitive considerations and incorporate occupational therapy in practice.

Functional health literacy in a population-based sample in Florence: a cross-sectional study using the Newest Vital Sign

OBJECTIVES

To assess the level of functional health literacy (HL) and its antecedents and consequences in an adult population-based sample, using the Italian version of Newest Vital Sign (NVS-IT).

DESIGN

Cross-sectional study.

SETTING

General population.

PARTICIPANTS

984 people were randomly selected from the resident registers of 11 general practitioners; a total of 452 (46.2%) of the selected people completed the study. Inclusion criteria were the following: 18-69 years of age and Italian speaking. Exclusion criteria included cognitive impairment, severe psychiatric diseases and end-stage diseases.

OUTCOME MEASURES

HL levels as assessed by the NVS-IT and the following potential HL predictors and consequences were assessed using logistic regression models: sociodemographic characteristics, body mass index, presence of long-term illnesses, self-reported health status, health services use in the last 12 months.

RESULTS

High likelihood of limited HL, possibility of limited HL and adequate HL were found in 11.5%, 24.6% and 63.9% of the sample, respectively. The results of the multivariate logistic model for the antecedents showed that the risk of having high likelihood or possibility of limited HL levels increases with age (OR 1.07, 95% CI 1.05 to 1.09), lower educational level (OR 4.03; 95% CI 3.41 to 7.49) and with worse financial situation (OR 1.64; 95% CI 1.17 to 2.63). As far as health outcomes are concerned, HL resulted to be positively associated with self-reported health status (OR 2.25, 95% CI 1.75 to 2.75).

CONCLUSIONS

Findings show a good level of functional HL in the population. However, older, less educated and poorer population groups showed to have a higher likelihood of suffering from limited or inadequate HL. Efforts should be made to design and implement public health policies and interventions tailored to different HL levels.

Gender Differences in the Impact of Cognitive Function on Health Literacy among Older Adults with Heart Failure

Heart failure (HF)-related cognitive decline is a common condition and may be associated with health literacy. However, gender differences in this context have not been explored fully. This secondary data analysis aimed to identify gender differences in the impact of cognitive function on health literacy among older patients with HF. A total of 135 patients (75 men and 60 women) with a mean age of 73.01 ± 6.45 years were recruited. Older women with HF had higher cognitive impairment (15%) and inadequate health literacy (56.7%) compared to men. Cognitive function was the strongest predictor of health literacy in men (β = 3.668, p < 0.001) and women (β = 2.926, p = 0.004). Notably elderly women are likely to face double the burden of the influence of cognitive function on health literacy in comparison with men. It is necessary to assess cognitive function and health literacy during HF illness trajectories on a regular basis. Healthcare professionals working with patients with HF should be aware of gender differences in cognitive function and health literacy and the importance of assessing these factors.

Health Literacy in the German Population

BACKGROUND

Persons with low health literacy have difficulty dealing with the health care system and understanding health-related information. Studies from multiple countries have shown that low health literacy negatively affects health, health-related and illness-related behavior, and the utilization of health care resources. The data available till now on health literacy in Germany have been sparse. The goal of this study is to acquire representative data on the health literacy of the German population.

METHODS

In a cross-sectional study, we collected data from a representative group of 2000 persons over age 15 in Germany by means of computer-assisted personal interviews (CAPI) that were based on the long version of the questionnaire used in the European Health Literacy Survey (HLS-EU-Q47). Sociodemographic data were also collected.

RESULTS

The respondents were a representative sample of the German population. 54.3% of them were found to have limited health literacy. Multiple logistic regression revealed associations of limited health literacy with advanced age (odds ratio [OR] 1.83, 95% confidence interval [CI] [1.36; 2.48]), an immigrant background (OR 1.87 [1.27; 2.75]), low self-assessed social status (OR 5.25 [3.57; 7.72]), and low functional literacy (OR 1.94 [1.49; 2.52]).

CONCLUSION

The low health literacy of many Germans can impair communication between doctors and patients and exacerbate existing problems in health policy. In the future, greater effort will have to be made to foster health literacy, make health-related information for patients easier to understand, and intensify research in the field of health literacy.

Pharmacy-Based Approach to Improving Heart Failure Medication Use by Older Adults with Limited Health Literacy: Learning from Interdisciplinary Experience

Heart failure is a chronic disease requiring careful attention to self-care. Patients must follow instructions for diet and medication use to prevent or delay a decline in functional status, quality of life, and expensive care. However, there is considerable heterogeneity in heart failure patients' knowledge of important care routines, their cognition, and their health literacy, which predict the ability to implement self-care. Our interdisciplinary team of cognitive scientists with health literacy expertise, pharmacists, and physicians spent 18 years designing and testing protocols and materials to assist ambulatory heart failure patients with their care. Our approach is theory- as well as problem-driven, guided by our process-knowledge model of health literacy as it relates to self-care among older adult outpatients with either heart failure or hypertension. We used what we had learned from this model to develop a pharmacy-based protocol and tailored patient instruction materials that were the central component of a randomized clinical trial. Our results showed improved adherence to cardiovascular medications, improved health outcomes and patient satisfaction, and direct cost reductions. These results demonstrate the value of our interdisciplinary efforts for developing strategies to improve instruction and communication with attention to health literacy, which are core components of pharmacy and other ambulatory healthcare services. We believe attention to health literacy with medication use will result in improved health outcomes for older adult patients with heart failure and other complex chronic diseases.

Cognitive enhancement for the ageing world: opportunities and challenges

Population ageing and the global burden of dementia pose a major challenge for human societies and a priority for public health. Cognitive enhancement,i.e.the targeted amplification of core cognitive abilities, is raising increasing attention among researchers as an effective strategy to complement traditional therapeutic and assistive approaches, and reduce the impact of age-related cognitive disability. In this paper, we discuss the possible applicability of cognitive enhancement for public health purposes to mitigate the burden of population ageing and dementia. After discussing the promises and challenges associated with enhancing ageing citizens and people with cognitive disabilities, we argue that global societies have a moral obligation to consider the careful use of cognitive enhancement technologies as a possible strategy to improve individual and public health. In addition, we address a few primary normative issues and possible objections that could arise from the implementation of public health-oriented cognitive enhancement technologies.

A Multi-faceted Approach to Promote Comprehension of Online Health Information Among Older Adults

Purpose of the Study

Older adults' self-care often depends on understanding and utilizing health information. Inadequate health literacy among older adults poses a barrier to self-care because it hampers comprehension of this information, particularly when the information is not well-designed. Our goal was to improve comprehension of online health information among older adults with hypertension who varied in health literacy abilities.

Design and Methods

We identified passages about hypertension self-care from credible websites (typical passages). We used a multi-faceted approach to redesign these passages, revising their content, language, organization and format (revised passages). Older participants read both versions of the passages at their own pace. After each passage, they summarized the passage and then answered questions about the passage.

Results

Participants better remembered the revised than the typical passages, summarizing the passages more accurately and uptaking information more efficiently (less reading time needed per unit of information remembered). The benefits for reading efficiency were greater for older adults with more health knowledge, suggesting knowledge facilitated comprehension of information in the revised passages.

Implications

A systematic, multi-faceted approach to designing health documents can promote online learning among older adults with diverse health literacy abilities.

If you build it, they may not come: modifiable barriers to patient portal use among pre- and post-kidney transplant patients

Background

Patient access to health information using electronic patient portals is increasingly common. Portal use has the potential to improve patients’ engagement with their health and is particularly important for patients with chronic illness; however, patients’ abilities, attitudes, and use of portals are poorly understood.

Methods

A single-center, cross-sectional survey was conducted of 240 consecutive pre- and post-kidney transplant patients of all levels of technological proficiency who presented to an urban transplant center in the United States. The investigator-developed Patient Information and Technology Assessment-Patient Portal was used to assess patients’ attitudes towards the use of patient portals.

Results

Most patients surveyed did not use the patient portal (n = 176, 73%). Patients were more likely to use the patient portal if they were White, highly educated, in the post-transplant period, more comfortable with technology, and reported being a frequent internet user (P < .05). The most common reasons for not using the patient portal included: (1) preference for traditional communication, (2) not being aware of the portal, (3) low technological proficiency, and (4) poor interoperability between the portal at the transplant center and the patient’s primary care center.

Conclusions

We identified several modifiable barriers to patient portal use. Some barriers can be addressed by patient education and training on portal use, and federal initiatives are underway to improve interoperability; however, a preference for traditional communications represents the most prominent barrier. Additional strategies are needed to improve portal adoption by encouraging acceptance of technologies as a way of clinical communication.

Health literacy among caregivers of patients with heart failure: A multicentre cross-sectional survey

AIMS AND OBJECTIVES

To assess the levels of health literacy of Italian caregivers of patients with heart failure.

BACKGROUND

Health literacy is related to patients' health outcomes. Low health literacy has been found in older people with heart failure, and less is known on the health literacy of caregivers whose patients are suffering from heart failure.

DESIGN

Observational, multicentre, cross-sectional study.

METHODS

From July 2015-May 2016, caregivers were recruited in five hospitals from Central and Southern Italy. To assess health literacy, the Italian version of the Short Test of Functional Health Literacy tool was used.

RESULTS

A total of 173 caregivers participated in the research, the majority being females (60.1%), aged between 46-60 years (52.6%) and 96 (55.5%) were from Central Italy. 33.5% of caregivers were patients' children, and 16.2% were paid caregivers of foreign origins. The average level of health literacy was adequate; however, lower levels were found among patients' spouses and those of older age.

CONCLUSION

Our results, in contrast with previous studies, showed adequate health literacy levels of caregivers. However, caregivers older in age and with a low education level showed the lowest health literacy, emphasising the need for healthcare workers, to check caregivers' health literacy, before entrusting them with the care of patients.

RELEVANCE TO CLINICAL PRACTICE

As this research gives, for the first time, an overview on Italian caregivers' levels of health literacy, its results may be used to improve Italian healthcare professionals' knowledge of caregivers' health literacy, before entrusting them with the care of patients.

Health Literacy and Participation Among Older Adult Patients With Heart Failure in Korean Culture

Introduction: In South Korea, approximately 40% of older adults are reported to have low health literacy. The purpose of this study was to evaluate the relationship between health literacy and patient participation among Korean older adults with heart failure. Method: This cross-sectional descriptive study involved 145 Korean patients at one prominent medical center in South Korea. The Korean Health Literacy Scale short form and the 13-item Perceived Involvement in Care Scale were administered between June and September, 2016. Results: Among participants (mean age = 71.30 years; 26.9% female), approximately 30% had poor health literacy. A significant correlation was observed between health literacy and participation scores ( r = .538, p < .01). Health literacy was the most important predictor of patient participation (β = .488, p < .001). Discussion: The results imply that effective knowledge acquisition may encourage greater patient participation. By identifying health literacy in Korean older adults, we can provide more culturally congruent health care by improving participation between providers and patients.

Effectiveness of the teach-back method for improving the health literacy of senior citizens in nursing homes

AIM

To explore the effectiveness of the teach-back method for improving the health literacy of older adults in nursing homes in Ürümqi, the capital of Xinjiang, China.

METHODS

Among the 27 registered nursing homes, 10 were selected randomly by size and divided into the intervention and control groups. A total of 127 older adults in the intervention group and 136 in the control group met the inclusion criteria. The intervention and control groups were educated by using the teach-back and traditional methods, respectively, in this 6 month study. The Chinese Citizen Health Literacy Questionnaire was used to evaluate the effects of the interventions.

RESULTS

Pre-intervention, the health literacy level of the cohorts was relatively low. Postintervention, the total health literacy score of the intervention group increased, while the total health literacy score of the control group had increased to a lesser extent. The total and four-dimension scores of the two groups were statistically significant. The intergroup difference in the two groups, and the intervention group's total health literacy score and each dimension score were higher than in the control group; these differences were statistically significant .

CONCLUSIONS

The teach-back method can improve the health literacy level of older adults through short-term educational intervention. The teach-back method should be adopted by more healthcare providers and applied to improve the health literacy education of older adults.

Racial Differences in Neurocognitive Outcomes Post-Stroke: The Impact of Healthcare Variables

OBJECTIVES

The present study examined differences in neurocognitive outcomes among non-Hispanic Black and White stroke survivors using the NIH Toolbox-Cognition Battery (NIHTB-CB), and investigated the roles of healthcare variables in explaining racial differences in neurocognitive outcomes post-stroke.

METHODS

One-hundred seventy adults (91 Black; 79 White), who participated in a multisite study were included (age: M=56.4; SD=12.6; education: M=13.7; SD=2.5; 50% male; years post-stroke: 1-18; stroke type: 72% ischemic, 28% hemorrhagic). Neurocognitive function was assessed with the NIHTB-CB, using demographically corrected norms. Participants completed measures of socio-demographic characteristics, health literacy, and healthcare use and access. Stroke severity was assessed with the Modified Rankin Scale.

RESULTS

An independent samples t test indicated Blacks showed more neurocognitive impairment (NIHTB-CB Fluid Composite T-score: M=37.63; SD=11.67) than Whites (Fluid T-score: M=42.59, SD=11.54; p=.006). This difference remained significant after adjusting for reading level (NIHTB-CB Oral Reading), and when stratified by stroke severity. Blacks also scored lower on health literacy, reported differences in insurance type, and reported decreased confidence in the doctors treating them. Multivariable models adjusting for reading level and injury severity showed that health literacy and insurance type were statistically significant predictors of the Fluid cognitive composite (p<.001 and p=.02, respectively) and significantly mediated racial differences on neurocognitive impairment.

CONCLUSIONS

We replicated prior work showing that Blacks are at increased risk for poorer neurocognitive outcomes post-stroke than Whites. Health literacy and insurance type might be important modifiable factors influencing these differences. (JINS, 2017, 23, 640-652).

The Effects of Home-Based Cognitive Training on Verbal Working Memory and Language Comprehension in Older Adulthood

Effective language understanding is crucial to maintaining cognitive abilities and learning new information through adulthood. However, age-related declines in working memory (WM) have a robust negative influence on multiple aspects of language comprehension and use, potentially limiting communicative competence. In the current study (N = 41), we examined the effects of a novel home-based computerized cognitive training program targeting verbal WM on changes in verbal WM and language comprehension in healthy older adults relative to an active component-control group. Participants in the WM training group showed non-linear improvements in performance on trained verbal WM tasks. Relative to the active control group, WM training participants also showed improvements on untrained verbal WM tasks and selective improvements across untrained dimensions of language, including sentence memory, verbal fluency, and comprehension of syntactically ambiguous sentences. Though the current study is preliminary in nature, it does provide initial promising evidence that WM training may influence components of language comprehension in adulthood and suggests that home-based training of WM may be a viable option for probing the scope and limits of cognitive plasticity in older adults.

Health literacy and warfarin therapy at two anticoagulation clinics in Brazil

OBJECTIVE

Health literacy has been related to health-related conditions and health outcomes. Studies examining the association of health literacy and anticoagulation have had variable results. We sought to investigate the relations of health literacy and percentage of time in therapeutic range (TTR) in a vulnerable Brazilian cohort at two hospital-based anticoagulation clinics.

METHODS

We measured health literacy with the Short Assessment of Health Literacy for Portuguese-speaking Adults (SAHLPA-18) in 2015-2016. We identified the demographic and clinical characteristics associated with health literacy and related health literacy to TTR.

RESULTS

We enrolled 422 adults prescribed chronic warfarin therapy in our observational study (median age 62.1 years; 58.8% women; monthly income $200.00). The prevalence of inadequate health literacy (score 0-14 points) was 72.3% with a median score of 12 (quartiles, Q1=10; Q3=15) on the SAHLPA-18. The median TTR was 66.1%. In the multivariable logistic analysis, cognitive impairment and assistance with taking warfarin were associated with inadequate health literacy. Prosthetic heart valves and more school years were associated with adequate health literacy. Our analyses showed no significant relation between health literacy and TTR, analysing health literacy as a categorical (adjusted OR 1.05; 95% CI 0.65 to 1.70) or continuous variable (Spearman's coefficient 0.02; p=0.70).

CONCLUSIONS

Inadequate health literacy was highly prevalent in this impoverished Brazilian cohort receiving anticoagulation with warfarin. However, we did not identify an association between health literacy and TTR. Future investigations may consider the systemic factors that contribute towards successful anticoagulation outcomes for vulnerable patient cohorts with inadequate health literacy.

Cognition and Health Literacy in Older Adults' Recall of Self-Care Information

Purpose of the Study

Health literacy is associated with health outcomes presumably because it influences the understanding of information needed for self-care. However, little is known about the language comprehension mechanisms that underpin health literacy.

Design and Methods

We explored the relationship between a commonly used measure of health literacy (Short Test of Functional Health Literacy in Adults [STOFHLA]) and comprehension of health information among 145 older adults.

Results

Results showed that performance on the STOFHLA was associated with recall of health information. Consistent with the Process-Knowledge Model of Health Literacy, mediation analysis showed that both processing capacity and knowledge mediated the association between health literacy and recall of health information. In addition, knowledge moderated the effects of processing capacity limits, such that processing capacity was less likely to be associated with recall for older adults with higher levels of knowledge.

Implications

These findings suggest that knowledge contributes to health literacy and can compensate for deficits in processing capacity to support comprehension of health information among older adults. The implications of these findings for improving patient education materials for older adults with inadequate health literacy are discussed.

Health and Functional Literacy in Physical Rehabilitation Patients

BACKGROUND

People with disabilities, who face multiple barriers to care, experience health disparities, yet few studies have measured health literacy in this population.

OBJECTIVE

This study evaluated functional literacy, health literacy, fluid cognitive function, and self-reported health in people who live in community dwellings with spinal cord injury, stroke, or traumatic brain injury.

METHODS

Participants with a traumatic spinal cord injury, stroke, or traumatic brain injury, one-year postinjury, and age 18 to 85 years, completed a battery of instruments at three medical centers in the Midwestern U.S.: functional literacy (word recognition, vocabulary knowledge), health literacy (comprehension of prose, document, and quantitative health information), fluid cognitive function (memory, executive function, and processing speed), and patient-reported outcomes (mobility, fatigue, sadness, anxiety, social function, and overall health).

KEY RESULTS

There were strong correlations between functional literacy, health literacy, and fluid cognitive function. After adjustment for sociodemographic and clinical characteristics, higher health literacy was associated with better mobility, less anxiety, and better overall health; higher functional literacy was associated with less anxiety and better overall health; and higher fluid cognitive function was associated with better mobility, less sadness, better social function, and better overall health.

CONCLUSIONS

To effectively address limited health literacy among people with spinal cord injury, stroke, and traumatic brain injury, and ensure that they are able to be informed partners in their health care, intervention is required at the level of patients, providers, and health care delivery systems. A special consideration is to ensure that health information is both well-targeted to people's health literacy levels and accessible for people with a range of physical, cognitive, and sensory limitations. The multimedia self-administered health literacy measure used in this study could be useful to rehabilitation providers and designers of health information and interfaces. [Health Literacy Research and Practice. 2017;1(2):e71-e85.].

PLAIN LANGUAGE SUMMARY

Health literacy represents people's abilities to obtain, understand, and use health information to make informed decisions about their health and health care. People with disabilities face physical, attitudinal, economic, and structural barriers to care. Consideration of health literacy in rehabilitation practice can enhance the effectiveness of the patient-clinician relationship and help address the needs of this population.

Medication self-management skills and cognitive impairment in older adults hospitalized for heart failure: A cross-sectional study

Background:

Cognitive impairment is highly prevalent among older adults (aged ≥65 years) hospitalized for heart failure and has been associated with poor outcomes. Poor medication self-management skills have been associated with poor outcomes in this population as well. The presence and extent of an association between cognitive impairment and poor medication self-management skills in this population has not been clearly defined.

Objective:

We assessed the cognition of consecutive older adults hospitalized for heart failure, in relation to their medication self-management skills.

Methods:

We conducted a cross-sectional study of older adults (aged ≥65 years) who were hospitalized for heart failure and were being discharged home. Prior to discharge, we assessed cognition using the Mini-Cog. We also tested patients’ ability to read a pill bottle label, open a pill bottle safety cap, and allocate mock pills to a pill box. Pill allocation performance was assessed quantitatively (counts of errors of omission and commission) and qualitatively (patterns suggestive of knowledge-based mistakes, rule-based mistakes, or skill-based slips).

Results:

Of 55 participants, 22% were found to have cognitive impairment. Patients with cognitive impairment tended to be older as compared to those without cognitive impairment (mean age = 81 vs 76 years, p = NS). Patients with cognitive impairment had a higher prevalence of inability to read pill bottle label (prevalence ratio = 5.8, 95% confidence interval = 3.2–10.5, p = 0.001) and inability to open pill bottle safety cap (prevalence ratio = 3.3, 95% confidence interval = 1.3–8.4, p = 0.03). While most patients (65%) had pill-allocation errors regardless of cognition, those patients with cognitive impairment tended to have more errors of omission (mean number of errors = 48 vs 23, p = 0.006), as well as more knowledge-based mistakes (75% vs 40%, p = 0.03).

Conclusion:

There is an association between cognitive impairment and poor medication self-management skills. Medication taking failures due to poor medication self-management skills may be part of the pathway linking cognitive impairment to poor post-discharge outcomes among patients with heart failure transitioning from hospital to home.

Cardiovascular disease risk and secondary prevention of cardiovascular disease among patients with low health literacy

OBJECTIVE

To explore the association between health literacy and the risk of cardiovascular disease (CVD), and to assess the differential effects by health literacy level of a nurse-coordinated secondary prevention program (NCPP) in patients with coronary artery disease (CAD).

METHODS

Data were collected in two medical centres participating in the RESPONSE trial (Randomised Evaluation of Secondary Prevention by Outpatient Nurse SpEcialists). CVD risk profiles were assessed at baseline and 12-month follow-up using the Systematic Coronary Risk Evaluation (SCORE). Health literacy was assessed by the short Rapid Estimate of Adult Literacy in Medicine (REALM-D) and the Newest Vital Sign (NVS-D); self-reported health literacy was evaluated by the Set of Brief Screening Questions (SBSQ-D).

RESULTS

Among 201 CAD patients, 18% exhibited reading difficulties, 52% had difficulty understanding and applying written information, and 5% scored low on self-reported health literacy. Patients with low NVS-D scores had a higher CVD risk [mean SCORE 5.2 (SD 4.8) versus 3.3 (SD 4.1), p < 0.01]. Nurse-coordinated care seemed to reduce CVD risk irrespective of health literacy levels without significant differences.

CONCLUSION

Inadequate health literacy is prevalent in CAD patients in the Netherlands, and is associated with less favourable CVD risk profiles. Where many other forms of CVD prevention fail, nurse-coordinated care seems to be effective among patients with inadequate health literacy.

Mental health literacy as a mediator in use of mental health services among older korean adults

BACKGROUND

Existing literature suggests that mental health literacy is positively associated with mental health services utilization. Despite an aging population that faces significant mental health concerns in Korea, the role of mental health literacy on mental health services utilization is not known among older adults in Korea. This study aimed to (1) identify whether mental health literacy mediates the association between population characteristics and mental health services utilization and (2) identify an optimal path model for mental health services utilization among Korean older adults.

METHODS

Using a cross-sectional survey with a quota sampling strategy, we collected and analyzed responses from 596 community-dwelling individuals ages 65 years and older. We used structural equation modeling (SEM) to estimate the effect of mental health literacy as a mediator.

RESULTS

When controlling for other relevant covariates in the optimal path model, mental health literacy mediated the relationships between three socio-demographic factors (education, general literacy, and health status) and mental health services utilization. The model fit index shows that the SEM fits very well (CFI = 0.92, NFI = 0.90, RMSEA = 0.07).

CONCLUSIONS

Efforts to improve mental health literacy through community-based education programs may need to particularly target Korean older adults with the relevant socio-demographic characteristics to enhance their utilization of appropriate mental health services.

Health Literacy and Heart Failure: A Systematic Review

BACKGROUND

Low health literacy affects millions of Americans, putting those who are affected at a disadvantage and at risk for poorer health outcomes. Low health literacy can act as a barrier to effective disease self-management; this is especially true for chronic diseases such as heart failure (HF) that require complicated self-care regimens.

PURPOSE

This systematic review examined quantitative research literature published between 1999 and 2014 to explore the role of health literacy among HF patients. The specific aims of the systematic review are to (1) describe the prevalence of low health literacy among HF patients, (2) explore the predictors of low health literacy among HF patients, and (3) discuss the relationship between health literacy and HF self-care and common HF outcomes.

METHODS

A systematic search of the following databases was conducted, PubMed, CINAHL Plus, Embase, PsycINFO, and Scopus, using relevant keywords and clear inclusion and exclusion criteria.

CONCLUSIONS

An average of 39% of HF patients have low health literacy. Age, race/ethnicity, years of education, and cognitive function are predictors of health literacy. In addition, adequate health literacy is consistently correlated with higher HF knowledge and higher salt knowledge.

CLINICAL IMPLICATIONS

Considering the prevalence of low health literacy among in the HF population, nurses and healthcare professionals need to recognize the consequences of low health literacy and adopt strategies that could minimize its detrimental effect on the patient's health outcomes.

Cognitive function and health literacy are independently associated with heart failure knowledge

OBJECTIVES

Determine the relationship between cognitive function and health literacy in heart failure (HF) knowledge in patients with HF.

BACKGROUND

HF requires extensive, complex treatment; thus, cognition and health literacy may contribute to understanding and self-management of HF.

METHODS

Participants were 330 HF outpatients. Health literacy was assessed using the Medical Term Recognition Test and the Rapid Estimate of Adult Literacy in Medicine. Global cognitive function was screened with the Modified Mini-Mental Status Examination. HF knowledge was assessed with the Dutch Heart Failure Knowledge Scale (DHFKS).

RESULTS

Health literacy (β = .26, p < .001) and cognition (β = .36, p < .001) were related to DHFKS. Both scores were independently associated with DHFKS (health literacy: β = .13, p = .044 and cognition: β = .30, p < .001).

CONCLUSIONS

Impairments in health literacy and cognition were independently associated with reduced HF knowledge. Interventions should address both factors to be maximally effective.

Associations between health literacy and preventive health behaviors among older adults: findings from the health and retirement study

Background

While the association between inadequate health literacy and adverse health outcomes has been well documented, less is known about the impact of health literacy on health perceptions, such as perceptions of control over health, and preventive health behaviors.

Methods

We identified a subsample of participants (N = 707) from the Health and Retirement Study (HRS), a nationally representative sample of older adults, who participated in health literacy testing. Self-reported health literacy was measured with a literacy screening question, and objective health literacy with a summed score of items from the Test of Functional Health Literacy. We compared answers on these items to those related to participation in health behaviors such as cancer screening, exercise, and tobacco use, as well as self-referencing health beliefs.

Results

In logistic regression models adjusted for gender, education, race, and age, participants with adequate self-reported health literacy (compared to poorer levels of health literacy) had greater odds of participation in mammography within the last 2 years (Odds ratio [OR] = 2.215, p = 0.01) and participation in moderate exercise two or more times per week (OR = 1.512, p = 0.03). Participants with adequate objective health literacy had reduced odds of participation in monthly breast self-exams (OR = 0.369, p = 0.004) and reduced odds of current tobacco use (OR = 0.456, p = 0.03). In adjusted linear regression analyses, self-reported health literacy made a small but significant contribution to explaining perceived control of health (β 0.151, p = <0.001) and perceived social standing (β 0.112, p = 0.002).

Conclusion

In a subsample of older adult participants of the HRS, measures of health literacy were positively related to several health promoting behaviors and health-related beliefs and non-use of breast self-exams, a screening behavior of questionable benefit. These relationships varied however, between self-reported and objectively-measured health literacy. Further investigation into the specific mechanisms that lead higher literacy people to pursue health promoting actions appears clearly warranted.

Multiple Chronic Conditions and Psychosocial Limitations in Patients Hospitalized with an Acute Coronary Syndrome

BACKGROUND

As adults live longer, multiple chronic conditions have become more prevalent over the past several decades. We describe the prevalence of, and patient characteristics associated with, cardiac- and non-cardiac-related multimorbidities in patients discharged from the hospital after an acute coronary syndrome.

METHODS

We studied 2174 patients discharged from the hospital after an acute coronary syndrome at 6 medical centers in Massachusetts and Georgia between April 2011 and May 2013. Hospital medical records yielded clinical information including presence of eight cardiac-related and eight non-cardiac-related morbidities on admission. We assessed multiple psychosocial characteristics during the index hospitalization using standardized in-person instruments.

RESULTS

The mean age of the study sample was 61 years, 67% were men, and 81% were non-Hispanic whites. The most common cardiac-related morbidities were hypertension, hyperlipidemia, and diabetes (76%, 69%, and 31%, respectively). Arthritis, chronic pulmonary disease, and depression (20%, 18%, and 13%, respectively) were the most common noncardiac morbidities. Patients with ≥4 morbidities (37% of the population) were slightly older and more frequently female than those with 0-1 morbidity; they were also heavier and more likely to be cognitively impaired (26% vs 12%), have symptoms of moderate/severe depression (31% vs 15%), high perceived stress (48% vs 32%), a limited social network (22% vs 15%), low health literacy (42% vs 31%), and low health numeracy (54% vs 42%).

CONCLUSION

Multimorbidity, highly prevalent in patients hospitalized with an acute coronary syndrome, is strongly associated with indices of psychosocial deprivation. This emphasizes the challenge of caring for these patients, which extends well beyond acute coronary syndrome management.

Aging and Functional Health Literacy: A Systematic Review and Meta-Analysis

OBJECTIVES

To review the evidence on the association between age and limited health literacy, overall and by health literacy test, and to investigate the mediating role of cognitive function.

METHOD

The Embase, MEDLINE, and PsycINFO databases were searched. Eligible studies were conducted in any country or language, included participants aged ≥50 years, presented a measure of association between age and health literacy, and were published through September 2013.

RESULTS

Seventy analyses in 60 studies were included in the systematic review; 29 of these were included in the meta-analysis. Older age was strongly associated with limited health literacy in analyses that measured health literacy as reading comprehension, reasoning, and numeracy skills (random-effects odds ratio [OR] = 4.20; 95% confidence interval [CI]: 3.13-5.64). By contrast, older age was weakly associated with limited health literacy in studies that measured health literacy as medical vocabulary (random-effects OR = 1.19; 95% CI: 1.03-1.37). Evidence on the mediating role of cognitive function was limited.

DISCUSSION

Health literacy tests that utilize a range of fluid cognitive abilities and mirror everyday health tasks frequently observe skill limitations among older adults. Vocabulary-based health literacy skills appear more stable with age. Researchers should select measurement tests wisely when assessing health literacy of older adults.

Health Literacy Mediates the Relationship Between Age and Health Outcomes in Patients With Heart Failure

BACKGROUND

Previous studies have linked frequent rehospitalizations for heart failure (HF) and increased mortality with older age, higher severity of HF, lack of an evidence-based medication regimen, and inadequate health literacy. However, the pathway between age and health outcomes in patients with HF remains unknown. Therefore, the purpose of this study was to test whether the association between age and health outcomes can be explained by severity of HF, evidence-based medication use, and health literacy in patients with HF.

METHODS AND RESULTS

This was a longitudinal study of 575 rural patients with HF recruited from outpatient clinics and hospitals. Demographics, clinical data, and health literacy were collected at baseline. HF readmissions and cardiac mortality were followed for 2 years; 57% of patients were ≥ 65 years of age. Older patients with HF were more likely to have low health literacy and less likely to be prescribed angiotensin-converting enzyme inhibitors or β-blockers. Using Kaplan-Meier survival curves with log-rank tests, health outcomes were significantly worse in patients who were ≥ 65 years and in those with low health literacy. Separate Cox regressions revealed that age and health literacy predicted worse health outcomes (P = 0.006 and < 0.001, respectively). When health literacy was entered into the model, the hazard ratio for age changed from 1.49 to 1.29 (a 41% reduction); age was no longer a significant predictor of health outcomes, but health literacy remained significant (P < 0.001), demonstrating mediation.

CONCLUSIONS

Health literacy mediates the relationship between age and health outcomes in adults with HF.

Relevance of graph literacy in the development of patient-centered communication tools

OBJECTIVE

To determine the literacy skill sets of patients in the context of graphical interpretation of interactive dashboards.

METHODS

We assessed literacy characteristics of prostate cancer patients and assessed comprehension of quality of life dashboards. Health literacy, numeracy and graph literacy were assessed with validated tools. We divided patients into low vs. high numeracy and graph literacy. We report descriptive statistics on literacy, dashboard comprehension, and relationships between groups. We used correlation and multiple linear regressions to examine factors associated with dashboard comprehension.

RESULTS

Despite high health literacy in educated patients (78% college educated), there was variation in numeracy and graph literacy. Numeracy and graph literacy scores were correlated (r=0.37). In those with low literacy, graph literacy scores most strongly correlated with dashboard comprehension (r=0.59-0.90). On multivariate analysis, graph literacy was independently associated with dashboard comprehension, adjusting for age, education, and numeracy level.

CONCLUSIONS

Even among higher educated patients; variation in the ability to comprehend graphs exists.

PRACTICE IMPLICATIONS

Clinicians must be aware of these differential proficiencies when counseling patients. Tools for patient-centered communication that employ visual displays need to account for literacy capabilities to ensure that patients can effectively engage these resources.

Comprehensibility of Health-Related Documents for Older Adults with Different Levels of Health Literacy: A Systematic Review

A systematic review was conducted to assess the available evidence for the effectiveness of interventions aiming to improve the comprehensibility of health-related documents in older adults (≥50) with different levels of health literacy. Seven databases were searched (2005 forward), and references in relevant reviews were checked. The selection procedure was conducted by 2 independent reviewers. Data extraction and assessment of the quality of the resulting studies were conducted by 1 reviewer and checked for accuracy by a 2nd reviewer. A total of 38 intervention studies had a study population of older adults (n = 35) or made an explicit comparison between age groups, including older adults (n = 3). Inconsistent evidence was found for the importance of design features to enhance the comprehensibility of health-related documents. Only for narratives and multiple-feature revisions (e.g., combining revisions in textual and visual characteristics) did the included studies provide evidence that they may be effective for older adults. Using narrative formats and/or multiple-feature revisions of health-related documents seem to be promising strategies for enhancing the comprehensibility of health-related documents for older adults. The lack of consistent evidence for effective interventions stresses the importance of (a) replication and (b) the use of standardized research methodologies.

Health literacy in Beijing: an assessment of adults' knowledge and skills regarding communicable diseases

BACKGROUND

There have been a number of studies conducted to date looking at the issue of health literacy, but none have been conducted in Beijing, China. The aim of this study was to evaluate the communicable diseases health literacy (CDHL) levels of Beijing residents towards three key areas: knowledge, adoption of preventative measures/behaviours, and health skills.

METHODS

A structured survey was undertaken with Beijing residents aged ≥18 years. A multistage stratified sampling approach was used to identify and recruit residents. Participants were excluded if they were foreigners, residents of Hong Kong, Macau or Taiwan, or were unable to communicate in Mandarin.

RESULTS

The questionnaire was completed by 11052 participants, with a moderate accuracy rate (average: 61.3 %) and a good discrimination level (average: 0.428). Cronbach's alpha was 0.748. The items were grouped into three subscales representing knowledge, adoption of preventative measures and behaviours, and health skills. Correlations of the subscales and the Total Score is significant (P < 0.01), and all the three subscales correlate strongly with the Total Score The mean CDHL score of Beijing inhabitants was 15.28. The percentage of those who were identified as having adequate CDHL was 41 %.

CONCLUSIONS

The total CDHL level of residents in Beijing was relatively low, particularly in those residing in the suburbs, those above 60 years of age, manual workers, and the illiterates. Gender, age-group, level of education, occupation, self-reported health status and region were all shown to be significantly predictive of CDHL. It is important that more resources are dedicated to improving the CDHL in Beijing, given the risk of emerging and re-emerging infectious diseases in the region.

The Potential for Literacy to Shape Lifelong Cognitive Health

In light of population aging, an understanding of factors that promote lifelong cognitive resilience is urgent. There is considerable evidence that education early in the life span, which promotes the development of literacy skills, leads to cognitive health and longevity, but the ways in which activity engagement in later adulthood affects long-term cognitive health is not well understood. The literature on cognitive training focusing on ability and skill training has not only demonstrated the existence of plasticity into late life but also shows that improvements are very tightly tied to the abilities trained. The rush to apply ability training to promote cognitive health has produced a vibrant “brain training” industry that neglects the very limited evidence for transfer to significant functional outcomes. Recent evidence on the neural substrates of reading, language comprehension, and discourse processing, as well as on the lifelong effects of literacy engagement in special populations, hints that reading may well be a “whole-brain exercise” with the potential to promote cognitive health. Such findings suggest promise for education-based approaches to promote lifelong cognitive health, calling for (a) societal investment in science at the interface of education and health, in particular to understand the mechanisms through which literacy engagement affects mind, brain, and physical health through the life span, and (b) innovation in developing models of life span education.

Health literacy, cognitive function, proper use, and adherence to inhaled asthma controller medications among older adults with asthma

BACKGROUND

We sought to investigate the degree to which cognitive skills explain associations between health literacy and asthma-related medication use among older adults with asthma.

METHODS

Patients aged ≥ 60 years receiving care at eight outpatient clinics (primary care, geriatrics, pulmonology, allergy, and immunology) in New York, New York, and Chicago, Illinois, were recruited to participate in structured, in-person interviews as part of the Asthma Beliefs and Literacy in the Elderly (ABLE) study (n = 425). Behaviors related to medication use were investigated, including adherence to prescribed regimens, metered-dose inhaler (MDI) technique, and dry powder inhaler (DPI) technique. Health literacy was measured using the Short Test of Functional Health Literacy in Adults. Cognitive function was assessed in terms of fluid (working memory, processing speed, executive function) and crystallized (verbal) ability.

RESULTS

The mean age of participants was 68 years; 40% were Hispanic and 30% non-Hispanic black. More than one-third (38%) were adherent to their controller medication, 53% demonstrated proper DPI technique, and 38% demonstrated correct MDI technique. In multivariable analyses, limited literacy was associated with poorer adherence to controller medication (OR, 2.3; 95% CI, 1.29-4.08) and incorrect DPI (OR, 3.51; 95% CI, 1.81-6.83) and MDI (OR, 1.64; 95% CI, 1.01-2.65) techniques. Fluid and crystallized abilities were independently associated with medication behaviors. However, when fluid abilities were added to the model, literacy associations were reduced.

CONCLUSIONS

Among older patients with asthma, interventions to promote proper medication use should simplify tasks and patient roles to overcome cognitive load and suboptimal performance in self-care.
