Health literacy and medication adherence in adolescents

OBJECTIVE

To assess the relationship between health literacy levels and medication adherence in adolescents.

STUDY DESIGN

A convenience sample of adolescents ages 12-21 years was recruited April-September 2011 at an urban adolescent health center. Health literacy and medication adherence was measured via the Rapid Estimate of Adult Literacy in Medicine-TEEN (REALM-TEEN) and Adherence to Refills and Medications Scale. The interrelated effects of age, sex, chronic illness, learning disability, health rating, and health literacy on adherence to medication were explored via the use of regression trees.

RESULTS

Of 138 adolescents surveyed, 112 (81%) were included in the analysis because they reported ever taking a medication and completed all survey questions. Median participant age was 16.1 years, 94% were African American, and 64% were female. Median REALM-TEEN score was 57 (6th-7th grade; range 0-66). Median ARMS score was 21 (poor; range 0-56). A positive correlation was found between worse adherence (greater ARMS scores) and self-report of a learning disability (P = .041), and between ARMS scores and having a chronic illness (P = .003). The ARMS and REALM-TEEN scores were not correlated (P = .069). Regression tree analysis indicated that adolescents with both a chronic illness and a learning disability had worse ARMS scores (median score 24), compared with adolescents having only a chronic illness (median score 22), independent of health literacy scores.

CONCLUSION

Almost one-quarter of adolescents reported having a learning disability and had worse medication adherence independent of health literacy levels. This finding suggests other cognitive factors, beyond reading, may play a role in medication adherence.

Evaluating the usefulness of patient education materials on surgical site infection: a systematic assessment

Patient education is important for the prevention of surgical site infections (SSIs). The usefulness of available patient education materials is unclear. Using a validated evaluation tool, the Patient Education Materials Assessment Tool, we systematically assessed patient education materials for SSI. We found that available materials performed poorly, and further research is needed in this area.

Can patient portals reduce health disparities? A perspective from asthma

Much asthma research directed at achieving health equity is focused on patient education for self-management. Although adults are more likely to die from asthma, most studies target children. With the advent of the electronic health record, patient portals potentially offer adult patients as well as children and their caretakers a resource for disease management education, facilitating communication with health care providers and improving patient access to health care. However, difficult, limited, or inconvenient access to these patient portals could increase health disparities, whereas features such as accompanying audio platforms, the use of multimedia, and the ability to communicate across language barriers and educational levels potentially could improve communication and reduce differences in health outcomes.

Feasibility of an intervention to enhance preventive care for people with low health literacy in primary health care

The objective of the study was to explore the feasibility of an intervention that enhances preventive care for primary care patients with low health literacy. A mixed method study was conducted in four Sydney general practices in areas of socioeconomic disadvantage. The intervention included screening for low health literacy in patients aged 40–69 years, clinical record audits of care for prevention of diabetes and cardiovascular disease, and provider training and meetings. Surveys and interviews were conducted to identify providers’ approaches to, and delivery of, preventive care for people with low health literacy. Our study found variable response rates and prevalence of low health literacy. Of the eligible patients screened, 29% had low health literacy. Providers described three approaches to preventive care, which remained largely unchanged. However, they demonstrated recognition of the importance of better communication and referral support for patients with low health literacy. Fewer patients with low health literacy were identified than expected. Despite improved awareness of the need for better communication, there was limited evidence of change in providers’ approach to providing preventive care, suggesting a need for more attention towards providers’ attitudes to support these patients.

Health Literacy, Smoking, and Health Indicators in African American Adults

We examined cross-sectional associations of health literacy (HL) with smoking and other established health indicators among 1,467 African American adults. Data emanated from a longitudinal cohort study designed to investigate cancer risk factors among church-going African American adults. We conducted linear and logistic regression analyses to assess associations between HL and health indicators. HL was assessed using an established single-item screening question. Outcomes included indicators of poor physical health (cigarette smoking, self-rated general and physical health) and mental health (self-rated mental health, depressive symptoms, perceived stress). Nearly 19% of participants had low HL. Low HL was significantly associated with current smoking, poorer self-rated general and physical health, and higher perceived stress (ps < .05) even after we controlled for demographic variables (i.e., age, gender, relationship status) and indicators of socioeconomic status (i.e., education, income, insurance status). Low HL appears to be an independent risk factor for smoking and other indicators of poor physical and mental health in a large sample of African American adults. Future directions and clinical implications are discussed.

Health Literacy and Medication Adherence Among Patients Treated in a Free Health Clinic: A Pilot Study

BACKGROUND

A patient's health literacy is not routinely assessed during visits with a health care provider. Since low health literacy is a risk factor for poor health outcomes, assessing health literacy should be considered as part of the standard medical workup.

OBJECTIVES

To evaluate the health literacy levels and medication adherence of patients treated by pharmacists in both the general medicine and the chronic care clinics at an urban free health clinic.

METHODS

Eligible patients from the free health clinic completed the Rapid Estimate of Adult Literacy in Medicine (REALM), a health literacy measurement tool, during their clinic visit in 2011. Medication adherence was self-reported by the patients.

RESULTS

A total of 100 patients participated (mean age = 48). The majority of participants were female (56%) and white (55%). Most (64%) of the patients scored at a high school reading level according to REALM. Only 21% of participants read at a seventh- to eighth-grade level. Overall medication adherence rate was 73%. Forgetting to take medication was the most popular reason given for nonadherence.

CONCLUSION

Disease state and adherence were significantly related in patients with HIV/AIDS and hypertension. Patient's ethnicity was significantly associated with literacy levels (P < .05). Although patients' literacy levels were not significantly associated with self-reported adherence in this population, availability of a patient's baseline health literacy level as a part of the medical record may help clinicians to individualize their interaction based on the patient's health literacy level in order to achieve better health outcomes, including improved medication adherence, especially for underserved populations.

Effects of Health Literacy and Social Capital on Health Information Behavior

This study aimed to examine whether social capital (bonding and bridging social capital) attenuate the effect of low functional health literacy on health information resources, efficacy, and behaviors. In-person interviews were conducted with 1,000 residents in Seoul, Korea, in 2011. The authors found that respondents' functional health literacy had positive effects on the scope of health information sources and health information self-efficacy but not health information-seeking intention. Respondents' social capital had positive effects on the scope of health information sources, health information efficacy, and health information-seeking intention. The authors found (a) a significant moderation effect of bridging social capital on the relation between health literacy and health information self-efficacy and (b) a moderation effect of bonding social capital on the relation between health literacy and health information-seeking intention.

Feasibility of "Standardized Clinician" Methodology for Patient Training on Hospital-to-Home Transitions

INTRODUCTION

Patient engagement in health care is increasingly recognized as essential for promoting the health of individuals and populations. This study pilot tested the standardized clinician (SC) methodology, a novel adaptation of standardized patient methodology, for teaching patient engagement skills for the complex health care situation of transitioning from a hospital back to home.

METHODS

Sixty-seven participants at heightened risk for hospitalization were randomly assigned to either simulation exposure-only or full-intervention group. Both groups participated in simulation scenarios with "standardized clinicians" around tasks related to hospital discharge and follow-up. The full-intervention group was also debriefed after scenario sets and learned about tools for actively participating in hospital-to-home transitions. Measures included changes in observed behaviors at baseline and follow-up and an overall program evaluation.

RESULTS

The full-intervention group showed increases in observed tool possession (P = 0.014) and expression of their preferences and values (P = 0.043). The simulation exposure-only group showed improvement in worksheet scores (P = 0.002) and fewer engagement skills (P = 0.021). Both groups showed a decrease in telling an SC about their hospital admission (P < 0.05). Open-ended comments from the program evaluation were largely positive.

CONCLUSIONS

Both groups benefited from exposure to the SC intervention. Program evaluation data suggest that simulation training is feasible and may provide a useful methodology for teaching patient skills for active engagement in health care. Future studies are warranted to determine if this methodology can be used to assess overall patient engagement and whether new patient learning transfers to health care encounters.

Effects of patient health literacy, patient engagement and a system-level health literacy attribute on patient-reported outcomes: a representative statewide survey

Background

The effects of health literacy are thought to be based on interactions between patients’ skill levels and health care system demands. Little health literacy research has focused on attributes of health care organizations. We examined whether the attribute of individuals’ experiences with front desk staff, patient engagement through bringing questions to a doctor visit, and health literacy skills were related to two patient-reported outcomes.

Methods

We administered a telephone survey with two sampling frames (i.e., household landline, cell phone numbers) to a randomly selected statewide sample of 3358 English-speaking adult residents of Missouri. We examined two patient-reported outcomes – whether or not respondents reported knowing more about their health and made better choices about their health following their last doctor visit. Multivariable logistic regression models were used to examine the independent contributions of predictor variables (i.e., front desk staff, bringing questions to a doctor visit, health literacy skills).

Results

Controlling for self-reported health, having a personal doctor, time since last visit, number of chronic conditions, health insurance, and sociodemographic characteristics, respondents who had a good front desk experience were 2.65 times as likely (95% confidence interval [CI]: 2.13, 3.30) and those who brought questions were 1.73 times as likely (95% CI: 1.32, 2.27) to report knowing more about their health after seeing a doctor. In a second model, respondents who had a good front desk experience were 1.57 times as likely (95% CI: 1.26, 1.95) and those who brought questions were 1.66 times as likely (95% CI: 1.29, 2.14) to report making better choices about their health after seeing a doctor. Patients’ health literacy skills were not associated with either outcome.

Conclusions

Results from this representative statewide survey may indicate that one attribute of a health care organization (i.e., having a respectful workforce) and patient engagement through question asking may be more important to patient knowledge and health behaviors than patients’ health literacy skills. Findings support focused research to examine the effects of organizational attributes on patient health outcomes and system-level interventions that might enhance patient health.

A group-randomized trial of shared decision making for non-steroidal anti-inflammatory drug risk awareness: primary results and lessons learned

RATIONALE, AIMS AND OBJECTIVES

Frequent use and serious adverse effects related to non-steroidal anti-inflammatory drugs (NSAIDs) underscore the need to raise patient awareness about potential risks. Partial success of patient- or provider-based interventions has recently led to interest in combined approaches focusing on both patient and physician. This research tested a shared decision-making intervention for increasing patient-reported awareness of NSAID risk.

METHODS

A group randomized trial was performed in Alabama from 2005 to 2007. Intervention group doctor practices received continuing medical education (CME) about NSAIDs and patient activation tools promoting risk assessment and communication during visits. Comparison group doctor practices received only CME. Cross-sectional data were collected before and after the intervention. Generalized linear latent and mixed models with logistic link tested relationships among the intervention, study phase, intervention by study phase interaction and patient-reported awareness of risks with either prescription or over-the-counter (OTC) NSAIDs.

RESULTS

Three hundred and forty-seven patients at baseline and 355 patients at follow-up participated in this study. The intervention [adjusted odds ratio (AOR)=0.74, P=0.248], follow-up study phase (AOR=1.31, P=0.300) and intervention by study phase interaction (AOR=0.98, P=0.942) were not significantly associated with patient-reported awareness of any prescription NSAID risk. Follow-up study phase was associated with increased odds of reporting any OTC NSAID risk awareness (AOR=2.99, P<0.001), but the patient activation intervention and intervention by study phase interaction were not significantly associated with patient-reported awareness of any OTC NSAID risk (AOR=0.98, P=0.929; AOR=0.87, P=0.693, respectively).

CONCLUSIONS

Our point-of-care intervention encouraging shared decision making did not increase NSAID risk awareness.

Health literacy issues surrounding weight management among African American women: a mixed methods study

BACKGROUND

Individuals with limited health literacy (LHL) have poorer health outcomes and have difficulty understanding and complying with recommendations to maintain a healthy lifestyle. The present study examined the association between health literacy (HL) and sources of dieting information, the weight-loss methods used and the information needed to manage weight among African American women.

METHODS

This mixed method study included seven focus groups and a survey of 413 African American women. Binary logistic regression analyses were performed to examine the association between HL category and sources of dieting information, weight-loss methods and information needed to lose weight. Thematic analysis was used to analyse focus group data.

RESULTS

Women with LHL were significantly more likely to have a higher body mass index (BMI) than those with AHL (P < 0.05). Compared to respondents with LHL, those with adequate health literacy (AHL) are more likely to rely on information obtained from the Internet (P < 0.001), although they are less likely to rely on information obtained from the television (P < 0.05). They also are significantly more likely to participate in physical activity to lose weight (P ≤ 0.002). In addition, women with AHL were significantly less likely to want information on portion control (P = 0.002). Major qualitative themes were the importance of television and the Internet as major sources of health information, the use of healthy and unhealthy weight-loss methods, and being overwhelmed by the plethora of dieting information.

CONCLUSIONS

HL may affect BMI among AA women, where they access dieting information and the types of information needed to manage their weight.

Regardless of age: Incorporating principles from geriatric medicine to improve care transitions for patients with complex needs

With its focus on holistic approaches to patient care, caregiver support, and delivery system redesign, geriatrics has advanced our understanding of optimal care during transitions. This article provides a framework for incorporating geriatrics principles into care transition activities by discussing the following elements: (1) identifying factors that make transitions more complex, (2) engaging care "receivers" and tailoring home care to meet patient needs, (3) building "recovery plans" into transitional care, (4) predicting and avoiding preventable readmissions, and (5) adopting a palliative approach, when appropriate, that optimizes patient and family goals of care. The article concludes with a discussion of practical aspects of designing, implementing, and evaluating care transitions programs for those with complex care needs, as well as implications for public policy.

Self-management behaviors in older adults with asthma: associations with health literacy

OBJECTIVES

To examine self-management behaviors, including medication adherence and inhaler technique, in older adults with asthma and their association with health literacy.

DESIGN

Observational cohort study.

SETTING

Primary care and pulmonary specialty practices in two tertiary academic medical centers and three federally qualified health centers in New York, New York, and Chicago, Illinois.

PARTICIPANTS

Adults with moderate or severe persistent asthma aged 60 and older (N = 433).

MEASUREMENTS

Outcomes were adherence to asthma controller medications, metered dose inhaler (MDI) and dry powder inhaler (DPI) techniques, having a usual asthma physician, and avoidance of four common triggers. Health literacy was assessed using the Short Test of Functional Health Literacy in Adults.

RESULTS

The mean age was 67, and 36% of participants had marginal or low health literacy. Adherence was low (38%) overall and worse in individuals with low health literacy (22%) than in those with adequate literacy (47%, P < .001) and after adjusting for demographic factors and health status (odds ratio (OR) = 0.48, 95% confidence interval (CI) = 0.31-0.73). Similarly, inhaler technique was poor; only 38% and 54% had good MDI and DPI technique, respectively. Technique was worse in those with low health literacy (MDI technique: OR = 0.57, 95% CI = 0.38-0.85; DPI technique: OR = 0.42, 95% CI = 0.25-0.71). Asthma self-monitoring and avoidance of triggers occurred infrequently but were less consistently associated with low health literacy.

CONCLUSION

Adherence to medications and inhaler technique are poor in older adults with asthma and worse in those with low health literacy. Clinicians should routinely assess controller medication adherence and inhaler technique and use low-literacy communication strategies to support self-management in older adults with asthma.

Effect of cognitive dysfunction on the relationship between age and health literacy

OBJECTIVE

Age is generally an inverse predictor of health literacy. However, the role of cognitive dysfunction among older adults in this relationship is not understood.

METHODS

We conducted a cross-sectional survey of 446 adult patients in a large urban academic level one trauma center, assessing health literacy and cognitive dysfunction.

RESULTS

Removing older patients (60 years of age and older) who screened positive for cognitive dysfunction attenuated the relationship between age and health literacy (r=-0.16, p=0.001 vs. r=-0.35, p<0.0001). Older patients screening positive for cognitive dysfunction had significantly lower health literacy than older patients screening negative and patients less than 60 years; health literacy scores did not generally differ significantly between the latter groups.

CONCLUSION

Much of the relationship between age and health literacy was driven by cognitive dysfunction among a subset of older adults.

PRACTICE IMPLICATIONS

Our findings suggest that older patients with cognitive dysfunction have the greatest need for health literacy interventions.

ACOG Committee Opinion No. 585: Health literacy

According to the Institute of Medicine of the National Academies, health literacy is defined as the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions. The American College of Obstetricians and Gynecologists is committed to the promotion of health literacy for all. Responsibility for recognizing and addressing the problem of limited health literacy lies with all entities in the health care arena-from the system level to the health care professional.

'I don't want to burden my family': handling communication challenges in geriatric oncology

Oncologists need excellent communication skills to effectively handle challenging conversations regarding prognosis, transition to palliative care, code status, and other sensitive topics. Foundational skills include: 1) posing open-ended, exploratory questions, 2) allowing for appropriate silence in the conversation, 3) listening actively, 4) recognizing emotions, 5) responding to emotions with empathy rather than biomedical information, and 6) speaking with clarity by avoiding technical jargon and offering small chunks of information. Conversations about sensitive topics can be particularly challenging with geriatric patients, who experience functional and sensory limitations. The risk-benefit ratio of diagnostic and therapeutic interventions tips precariously in older patients as many develop geriatric syndromes. Older cancer patients have the unique perspective of looking back on a long life and looking forward to impending death. Higher order skills can be very powerful in helping geriatric cancer patients find meaning and dignity at the end of life. These skills include exploring spirituality and coping strategies and engaging the patient in conversation and reflection about their legacy.

Preparedness of Americans for the Affordable Care Act

This paper investigates whether individuals are sufficiently informed to make reasonable choices in the health insurance exchanges established by the Affordable Care Act (ACA). We document knowledge of health reform, health insurance literacy, and expected changes in healthcare using a nationally representative survey of the US population in the 5 wk before the introduction of the exchanges, with special attention to subgroups most likely to be affected by the ACA. Results suggest that a substantial share of the population is unprepared to navigate the new exchanges. One-half of the respondents did not know about the exchanges, and 42% could not correctly describe a deductible. Those earning 100-250% of federal poverty level (FPL) correctly answered, on average, 4 out of 11 questions about health reform and 4.6 out of 7 questions about health insurance. This compares with 6.1 and 5.9 correct answers, respectively, for those in the top income category (400% of FPL or more). Even after controlling for potential confounders, a low-income person is 31% less likely to score above the median on ACA knowledge questions, and 54% less likely to score above the median on health insurance knowledge than a person in the top income category. Uninsured respondents scored lower on health insurance knowledge, but their knowledge of ACA is similar to the overall population. We propose that simplified options, decision aids, and health insurance product design to address the limited understanding of health insurance contracts will be crucial for ACA's success.

Treatment for chronic heart failure in the elderly: current practice and problems

Treatment for chronic heart failure (CHF) is strongly focused on evidence-based medicine. However, large trials are often far away from the "real world" of geriatric patients and their messages are poorly transferable to the clinical management of CHF elderly patients. Precipitating factors and especially non-cardiac comorbidity may decompensate CHF in the elderly. More importantly, drugs of first choice, such as angiotensin-converting enzyme inhibitors and β-blockers, are still underused and effective drugs on diastolic dysfunction are not available. Poor adherence to therapy, especially for cognitive and depression disorders, worsens the management. Electrical therapy is indicated, but attention to the older age groups with reduced life expectancy has to be paid. Physical exercise, stem cells, gene delivery, and new devices are encouraging, but definitive results are still not available. Palliative care plays a key role to the end-stage of the disease. Follow-up of CHF elderly patient is very important but tele-medicine is the future. Finally, self-care management, caregiver training, and multidimensional team represent the critical point of the treatment for CHF elderly patients.

How can health literacy influence outcomes in heart failure patients? Mechanisms and interventions

Health literacy is discussed in papers from 25 countries where findings suggest that approximately a third up to one half of the people in developed countries have low health literacy. Specifically, health literacy is the mechanism by which individuals obtain and use health information to make health decisions about individual treatments in the home, access care in the community, promote provider-patient interactions, structure self-care, and navigate health care programs both locally and nationally. Further, health literacy is a key determinant of health and a critical dimension for assessing individuals' needs, and, importantly, their capacity for self-care. Poorer health knowledge/status, more medication errors, costs, and higher rates of morbidity, readmissions, emergency room visits, and mortality among patients with health illiteracy have been demonstrated. Individuals at high risk for low health literacy include the elderly, disabled, Blacks, those with a poverty-level income, some or less high school education, either no insurance or Medicare or Medicaid, and those for whom English is a second language. As a consequence, health literacy is a complex, multifaceted, and evolving construct including aspects of social, psychological, cultural and economic circumstances. The purpose of this paper is to describe the mechanisms and consequences of health illiteracy. Specifically, the prevalence, associated demographics, and models of health literacy are described. The mechanism of health illiteracy's influence on outcomes in heart failure is proposed. Tools for health literacy assessment are described and compared. Finally, the health outcomes and general interventions to enhance the health outcomes in heart failure are discussed.

Mobile and web-based education: delivering emergency department discharge and aftercare instructions

Prior research has identified deficiencies in the standard process of providing instructions for care at discharge from the emergency department (ED). Patients typically receive a brief verbal instruction, along with preformatted written discharge documents. Studies have found that understanding and retention of such information by families are very poor, leading to nonadherence in follow-up care, unnecessary return visit to the ED, and poor health outcomes. The combination of systems factors (information content, delivery methods, and timing) and patient factors (health literacy, language proficiency, and cultural factors) contributes to the challenge of providing successful discharge communication. Internet and mobile devices provide a novel opportunity to better engage families in this process.Mobile health can address both system- and patient-level challenges. By incorporating images, animation, and full Web-based video content, more comprehensible content that is better suited for patients with lower health literacy and today's visual learners can be created. Information can also be delivered both synchronously and asynchronously, enabling the health care providers to deliver health education to the patients electronically to their home, where health care occurs. Furthermore, the providers can track information access by patients, customize content to the individual patients, and reach other caregivers who may not be present during the ED visit. Further research is needed to develop the systems and best practices for incorporating mobile health in the ED setting.

Five-year follow-up of patients treated for coronary artery disease in the face of an increasing burden of co-morbidity and disease complexity (from the NHLBI Dynamic Registry)

Management of coronary artery disease (CAD) has evolved over the past decade, but there are few prospective studies evaluating long-term outcomes in a real-world setting of evolving technical approaches and secondary prevention. The aim of this study was to determine how the mortality and morbidity of CAD has changed in patients who have undergone percutaneous coronary intervention (PCI), in the setting of co-morbidities and evolving management. The National Heart, Lung, and Blood Institute Dynamic Registry was a cohort study of patients undergoing PCI at various time points. Cohorts were enrolled in 1999 (cohort 2, n = 2,105), 2004 (cohort 4, n = 2,112), and 2006 (cohort 5, n = 2,176), and each was followed out to 5 years. Primary outcomes were death, myocardial infarction (MI), coronary artery bypass grafting, repeat PCI, and repeat revascularization. Secondary outcomes were PCI for new obstructive lesions at 5 years, 5-year rates of death and MI stratified by the severity of coronary artery and co-morbid disease. Over time, patients were more likely to have multiple co-morbidities and more severe CAD. Despite greater disease severity, there was no significant difference in death (16.5% vs 17.6%, adjusted hazard ratio [HR] 0.89, 95% confidence interval [CI] 0.74 to 1.08), MI (11.0% vs 10.6%, adjusted HR 0.87, 95% CI 0.70 to 1.08), or repeat PCI (20.4% vs 22.2%, adjusted HR 0.98, 95% CI 0.85 to 1.17) at 5-year follow-up, but there was a significant decrease in coronary artery bypass grafting (9.1% vs 4.3%, adjusted HR 0.44, 95% CI 0.32 to 0.59). Patients with 5 co-morbidities had a 40% to 60% death rate at 5 years. There was a modestly high rate of repeat PCI for new lesions, indicating a potential failure of secondary prevention for this population in the face of increasing co-morbidity. Overall 5-year rates of death, MI, repeat PCI, and repeat PCI for new lesions did not change significantly in the context of increased co-morbidities and complex disease.

Functional health literacy and glycaemic control in older adults with type 2 diabetes: a cross-sectional study

OBJECTIVES

To investigate the relationship between functional health literacy and glycaemic control in a sample of older patients with type 2 diabetes.

DESIGN

Cross-sectional study.

SETTING

A government-financed outpatient geriatric clinic in São Paulo, Brazil.

PARTICIPANTS

129 older patients with type 2 diabetes, a mean (SD) age of 75.9 (6.2) years, a mean glycosylated haemoglobin (HbA1c) of 7.2% (1.4), of which 14.7% had no formal education and 82.9% had less than a high-school diploma.

MEASURES

HbA1c was used as a measure of glycaemic control. Functional health literacy was assessed with the 18-item Short Assessment of Health Literacy for Portuguese-speaking Adults (SAHLPA-18), a validated instrument to evaluate pronunciation and comprehension of commonly used medical terms. Regression models were controlled for demographic data, depressive symptoms, diabetes duration, treatment regimen, diabetes knowledge and assistance for taking medications.

RESULTS

Functional health literacy below adequate was encountered in 56.6% of the sample. After controlling for potential confounding factors, patients with inadequate functional health literacy were more likely than patients with adequate functional health literacy to present poor glycaemic control (OR=4.76; 95% CI 1.36 to 16.63). In a fully adjusted linear regression model, lower functional health literacy (β=-0.42; p<0.001), longer diabetes duration (β=0.24; p=0.012) and lack of assistance for taking medications (β=0.23; p=0.014) were associated with higher levels of HbA1c. Contrary to our expectations, illiterate patients did not have poorer outcomes when compared with patients with adequate functional health literacy, raising the hypothesis that illiterate individuals are more likely to have their difficulties recognised and compensated. However, the small subsample of illiterate patients provided limited power to reject differences with small magnitude.

CONCLUSIONS

Patients with inadequate functional health literacy presented with higher odds of poor glycaemic control. These findings reinforce the importance of addressing limited functional health literacy in clinical practice.

Health Literacy Among Insulin-Taking African Americans

Aims

To determine the levels of functional health literacy (FHL) among insulin-taking African Americans with diabetes from an urban medical practice and to determine if associations exist between FHL levels and glycemic control.

Methods

Seventy insulin-taking African Americans seen for diabetes management comprised the analysis cohort. Patients were 18 years or older, African American, had diabetes, and currently using insulin via syringe, pen, or insulin pump. All participants completed a one-time assessment of FHL levels, using the Newest Vital Sign (NVS). Scores ranged from 0 to 6 (0-1 = high likelihood of limited FHL; 2-3 = possibility of limited FHL; 4-6 = adequate FHL). A combination of t tests, Pearson’s chi-square tests, and multivariate logistic regression models were used to determine associations between glycemic control and FHL.

Results

Average age was 58.7, 59.1% were female, 90.8% with type 2 diabetes, and 15.1% using an insulin pump. Glycemic control was: A1C < 7%: 22.9%, A1C < 8%: 47.1%. Of participants, 47.1% had adequate FHL, 31.4% had possible limited FHL, and 21.4% had a high likelihood of limited FHL. Also, 67.7% of participants with A1C ≥ 8% had a high likelihood of limited FHL. After adjusting for age and gender, participants with a high likelihood of limited FHL were 6.2 times (95% confidence interval [CI], 1.4-28.3) more likely to have A1C ≥ 8%.

Conclusions

Insulin-taking African Americans with a high likelihood of limited FHL are approximately 6 times more likely to have an A1C ≥ 8% compared to patients with a possibility of limited FHL, or adequate FHL, demonstrating the need for focused interventions tailored to FHL needs.

The association of health literacy with physical activity and nutritional behavior in older adults, and its social cognitive mediators

Inadequate health literacy is a common problem among older adults and is associated with poor health outcomes. Insight into the association between health literacy and health behaviors may support interventions to mitigate the effects of inadequate health literacy. The authors assessed the association of health literacy with physical activity and nutritional behavior in community-dwelling older adults. The authors also assessed whether the associations between health literacy and health behaviors are mediated by social cognitive factors. Data from a study among community-dwelling older adults (55 years and older) in a relatively deprived area in The Netherlands were used (baseline n=643, response: 43%). The authors obtained data on health literacy, physical activity, fruit and vegetable consumption, and potential social cognitive mediators (attitude, self-efficacy, and risk perception). After adjustment for confounders, inadequate health literacy was marginally significantly associated with poor compliance with guidelines for physical activity (OR=1.52, p=.053) but not with poor compliance with guidelines for fruit and vegetable consumption (OR=1.20, p=.46). Self-efficacy explained 32% of the association between health literacy and compliance with physical activity guidelines. Further research may focus on self-efficacy as a target for interventions to mitigate the negative effects of inadequate health literacy.

Patient information in Graves' disease and thyroid-associated ophthalmopathy: readability assessment of online resources

BACKGROUND

The Internet is a vital source of information for patients hoping to learn more about their disease. Health literacy of the general population is known to be poor, with the U.S. Department of Health and Human Services (USDHHS) recommending that patient-oriented literature be written at a fourth- to sixth-grade reading level to optimize comprehensibility. In this study we assessed the readability of online literature specifically for Graves' disease (GD) and thyroid-associated ophthalmopathy (TAO).

METHODS

Readability of the content of the top 20 English-language GD patient-oriented online resources and top 30 of the equivalent TAO resources returned by Google search was analyzed. Web pages were identified using the Google search terms "Graves' disease" and "Thyroid-Associated Ophthalmopathy," respectively. Extraneous text (e.g., hyperlinks, affiliations, disclaimers) was removed. Relevant text proceeded to readability analysis using four validated measures: Flesch Reading Ease Score, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook, and Gunning-Fog Index. Readability was compared with USDHHS standards.

RESULTS

Overall, median word count (with interquartile range [IQR] and range) was 990 (IQR 846, 195-3867), with a median of 18 words per sentence (IQR 4.0, 7.5-28). Median Flesch Reading Ease Score was 46 (IQR 13, 24-64), Flesch-Kincaid Grade Level 11 (IQR 3.0, 7.2-17), Simple Measure of Gobbledygook 13 (IQR 2.0, 9.6-17), and Gunning-Fog Index 13 (IQR 3.0, 9.2-19), each equivalent to a reading level of >11th grade and "difficult" on the USDHHS classification. None of the web pages evaluated had readability scores in accordance with published guidelines. There was no significant difference with the country of origin of each web page, website commercial status, or with pages predominantly focused on GD or TAO.

CONCLUSIONS

Readability scores for online GD and TAO patient-focused materials are inferior to those recommended. Screening of this online material, as well as subsequent revision, is crucial to increase future patient knowledge, satisfaction, and compliance.

Variation in Older Americans Act caregiver service use, unmet hours of care, and independence among Hispanics, African Americans, and Whites

Home- and community-based services (HCBS) are underused by minority seniors and their caregivers, despite greater rates of disability. We examined racial/ethnic variation among 1,749 Hispanics, African Americans, and Whites receiving Older Americans Act Title III caregiver services in 2009. In addition, we identified the volume of services used by caregivers, their unmet hours of respite care, and the relationship between service use and seniors' ability to live independently. Minority caregivers cared for seniors in urban areas who had higher rates of disability, poverty, and Medicaid coverage. Hispanics had the highest rate of unmet hours of care, while caregiver services were less likely to help African Americans remain at home. Minorities sought services through community agencies and were more educated than demographically similar national cohorts. Greater efforts to reach minority caregivers of less educated, disabled seniors in urban areas and through community agencies may reduce unmet needs and support independent living.

Exploring the impact of a community hospital closure on older adults: a focus group study

The closing of hospitals has exacerbated challenges for older adults in accessing healthcare, especially those living in economically underserved settings. Through focus groups and a community-engaged approach, our study examined and documented the emergent health needs of older adults following the closing of a local hospital in an economically disadvantaged community. Focus groups were reconvened to assess progress and health needs over time. Analyses of the focus groups (n=37, mean age 77, 84% female) illustrated the impact of the closure and the emergence of the following dominant themes: perceptions of the hospital system, including feelings of abandonment and social isolation; transportation challenges in accessing health care resources; and lack of knowledge and literacy regarding available health care and obtaining health services. Discussion sessions with hospital administrators and participants afforded an opportunity for sharing data and additional assessment. The data and relationships developed with community participants and health system representatives resulted in the production of an information resource about access to health services, tailored for older adults.

A single-item self-report medication adherence question predicts hospitalisation and death in patients with heart failure

AIMS AND OBJECTIVES

To determine whether a single-item self-report medication adherence question predicts hospitalisation and death in patients with heart failure.

BACKGROUND

Poor medication adherence is associated with increased morbidity and mortality. Having a simple means of identifying suboptimal medication adherence could help identify at-risk patients for interventions.

DESIGN

We performed a prospective cohort study in 592 participants with heart failure within a four-site randomised trial.

METHODS

Self-report medication adherence was assessed at baseline using a single-item question: 'Over the past seven days, how many times did you miss a dose of any of your heart medication?' Participants who reported no missing doses were defined as fully adherent, and those missing more than one dose were considered less than fully adherent. The primary outcome was combined all-cause hospitalisation or death over one year and the secondary endpoint was heart failure hospitalisation. Outcomes were assessed with blinded chart reviews, and heart failure outcomes were determined by a blinded adjudication committee. We used negative binomial regression to examine the relationship between medication adherence and outcomes.

RESULTS

Fifty-two percent of participants were 52% male, mean age was 61 years, and 31% were of New York Heart Association class III/IV at enrolment; 72% of participants reported full adherence to their heart medicine at baseline. Participants with full medication adherence had a lower rate of all-cause hospitalisation and death (0·71 events/year) compared with those with any nonadherence (0·86 events/year): adjusted-for-site incidence rate ratio was 0·83, fully adjusted incidence rate ratio 0·68. Incidence rate ratios were similar for heart failure hospitalisations.

CONCLUSION

A single medication adherence question at baseline predicts hospitalisation and death over one year in heart failure patients.

RELEVANCE TO CLINICAL PRACTICE

Medication adherence is associated with all-cause and heart failure-related hospitalisation and death in heart failure. It is important for clinicians to assess patients' medication adherence on a regular basis at their clinical follow-ups.

Bringing the real world to psychometric evaluation of cervical cancer literacy assessments with Black, Latina, and Arab women in real-world settings

This research describes the development and evaluation of a new scale for assessing functional cervical cancer health literacy, the Cervical Cancer Literacy Assessment Tool (C-CLAT). In phase 1, 35 items in English, Spanish, and Arabic for C-CLAT were generated, taking into account three content domains-Awareness, Knowledge, and Prevention/Control. After content validation, 24 items were retained for psychometric evaluation. In phase 2, the 24-item C-CLAT was evaluated in three racial/ethnic populations of urban women (N = 543). Psychometric methods included item analysis, multifactor item response theory modeling, and concurrent correlations. The final C-CLAT consisted of 16 items, with an internal consistency reliability of 0.72. C-CLAT reliabilities in Black, Latina, and Arab women were 0.73, 0.76, and 0.60, respectively. The rank order correlations of item difficulties across racial/ethnic groups was high (r's = 0.97 to 0.98). The C-CLAT was positively related to educational level, and Arab women scored significantly higher than the Black and Latina participants. This study presents a psychometrically sound instrument that measures health literacy related to cervical cancer. The C-CLAT is a tool that can be orally administered by a lay person and used in a community-based health promotion intervention.

Asthma outcomes are poor among older adults with low health literacy

OBJECTIVE

To examine the association of health literacy (HL) with asthma outcomes among older asthmatics.

METHODS

The study included adults ages ≥60 with moderate to severe asthma in New York City and Chicago. We assessed asthma control with the Asthma Control Questionnaire (ACQ) and the percent predicted forced expiratory volume at 1 s (FEV1) by spirometry, hospitalizations and emergency department (ED) visits in the past 6 months, and quality of life. HL was assessed with the Short Test of Functional Health Literacy in Adults (S-TOFHLA). Multivariate logistic regression models controlled for age, sex, race, income, general health and years with asthma.

RESULTS

Among 433 individuals, 36% had low HL, 55% were over age 65, 38% were Hispanic and 22% were black. Poor asthma control was reported by 40% and 32% had FEV1 <70% of predicted; 9% had a hospital stay, 23% had an ED and 38% had poor quality of life. In multivariable analysis, individuals with low HL were more likely to have FEV1 <70% predicted (odds ratio [OR] 2.34, 95% confidence interval [CI] 1.39-3.94, p = 0.001), hospitalizations (OR 2.53, 95% CI 1.17-5.49, p = 0.02) and ED visits for asthma (OR 1.81, 95% CI 1.05-3.10, p = 0.03). There were no differences in self-reported asthma control and quality of life.

CONCLUSIONS

Low HL is associated with poor asthma control by objective measure, and greater likelihood of ED visits and hospitalization. HL is a modifiable target for interventions to improve asthma outcomes in the elderly.

The association between health literacy and indicators of cognitive impairment in a diverse sample of primary care patients

OBJECTIVES

To confirm the association of health literacy scores as measured by Health Literacy Assessment Using Talking Touchscreen Technology (Health LiTT) with cognitive ability and education. To determine whether this association differs by cognitive task.

METHODS

Cognitive impairment was measured using the Mini-Cog, which combines a delayed word recall task (WRT) and a clock drawing task (CDT) to yield an overall classification of normal versus cognitively impaired. Participants were recruited from primary care clinics that provide care to underserved patients.

RESULTS

Participants (n=574) were predominantly non-Hispanic black (67%) with a mean age of 46 years, 50% did not have health insurance, 56% had a high school education or less and 21% screened positive for cognitive impairment. Overall cognitive ability and education were significantly associated with health literacy after adjusting for other variables, including race/ethnicity and physical health. We observed a stronger association between the CDT and health literacy than between the WRT and health literacy.

CONCLUSION

By confirming hypothesized associations, this study provides additional support of the validity of Health LiTT.

PRACTICE IMPLICATIONS

Health LiTT is a reliable and valid tool that researchers and clinicians can use to identify individuals who might have difficulty understanding health information.

Detecting limited health literacy in Brazil: development of a multidimensional screening tool

Screening questions have been proposed as practical tools for detecting limited functional health literacy, but have achieved only moderate accuracy in previous studies. We hypothesized that a combination of screening questions and demographic characteristics could better predict a patient's functional health literacy. Three hundred and twenty-two hospital users from São Paulo, Brazil, were interviewed for demographic information and answered questions about literacy habits and perceived difficulties. The Short Test of Functional Health Literacy in Adults was used to classify individuals as having adequate or limited functional health literacy. Of the 322 participants, 102 (31.7%) presented limited functional health literacy. The final logistic model included six predictors. The three demographic variables were educational attainment, mother's educational attainment and major lifetime occupation (manual or non-manual). The three questions concerned 'frequency of use of computers', 'difficulty with writing that have precluded the individual from getting a better job' and 'difficulty reading the subtitles while watching a foreign movie'. A simple score was derived to constitute a practical tool we named the Multidimensional Screener of Functional Health Literacy (MSFHL). The sensitivity of the MSFHL in detecting limited functional health literacy was 81.4% and the specificity was 87.7%, with an area under receiver operating characteristic (ROC) curve of 0.93 (95% CI 0.89-0.95). The MSFHL was better than educational attainment in accurately classifying functional health literacy status (p = 0.0018). We have developed a screening tool based on three demographic characteristics and three simple questions which provides an accurate prediction of a patient's functional health literacy level.

Predicting cancer risk knowledge and information seeking: the role of social and cognitive factors

This study tests an expanded Structural Influence Model (SIM) to gain a greater understanding of the social and cognitive factors that contribute to disparities in cancer risk knowledge and information seeking. At the core of this expansion is the planned risk information seeking model (PRISM). This study employed an online sample (N = 1,007) of African American, Hispanic, and non-Hispanic White adults. The addition of four cognitive predictors to the SIM substantially increased variance explained in cancer risk knowledge (R(2) = .29) and information seeking (R(2) = .56). Health literacy mediated the effects of social determinants (socioeconomic status [SES] and race/ethnicity) on cancer risk knowledge, while subjective norms mediated their effects on cancer risk information seeking. Social capital and perceived seeking control were also shown to be important mediators of the relationships between SES and cancer communication outcomes. Our results illustrate the social and cognitive mechanisms by which social determinants impact cancer communication outcomes, as well as several points of intervention to reduce communication disparities.

Remote monitoring of heart failure patients

"The Teledactyl (Tele, far; Dactyl, finger--from the Greek) is a future instrument by which it will be possible for us to 'feel at a distance.' This idea is not at all impossible, for the instrument can be built today with means available right now. It is simply the well known telautograph, translated into radio terms, with additional refinements. The doctor of the future, by means of this instrument, will be able to feel his patient, as it were, at a distance...The doctor manipulates his controls, which are then manipulated at the patient's room in exactly the same manner. The doctor sees what is going on in the patient's room by means of a television screen." -Hugo Gernsback, Science and Invention Magazine, February 1925 Heart failure continues to be a major burden on our health care system. As the number of patients with heart failure increases, the cost of hospitalization alone is contributing significantly to the overall cost of this disease. Readmission rate and hospital length of stay are emerging as quality markers of heart failure care along with reimbursement policies that force hospitals to optimize these outcomes. Apart from maintaining quality assurance, the disease process of heart failure per-se requires demanding and close attention to vitals, diet, and medication compliance to prevent acute decompensation episodes. Remote patient monitoring is morphing into a key disease management strategy to optimize care for heart failure. Innovative implantable technologies to monitor intracardiac hemodynamics also are evolving, which potentially could offer better and substantial parameters to monitor.

Racial/Ethnic Variability in Hypertension Prevalence and Risk Factors in National Health Interview Survey

Objective. Hypertension is one of the leading causes of death attributed to cardiovascular diseases, and the prevalence varies across racial/ethnic groups, with African Americans being disproportionately affected. The underlying causes of these disparities are not fully understood despite volume of literature in this perspective. We aimed in this current study to examine ethnic/racial disparities in hypertension utilizing Hispanics as the base racial/ethnic group for comparison. Research Design and Methods. We utilized the National Health Interview Survey (NHIS), which is a large cross-sectional survey of the United States non-institutionalized residents to investigate the racial/ethnic disparities in hypertension after the adjustment of other socio-economic, demographic, and prognostic risk factors. The study participants were adults (n = 30,852). Data were analyzed using Chi square statistic, and logistic regression model. Results. There were statistically significant differences by race/ethnicity with respect to income, education, marital status, smoking, alcohol, physical activities, body mass index, and age, P < 0.01, but not insurance coverage, P > 0.01. Hispanic ethnicity (18.9%) compared to either non-Hispanic white (27.7%) or non-Hispanic black (35.5%) was associated with the lowest prevalence of hypertension. Race/ethnicity was a single independent predictor of hypertension, with non-Hispanic black more likely to be hypertensive compare with Hispanic, prevalence odds ratio (POR), 2.38, 99% Confidence Interval (CI), 2.17–2.61 and non-Hispanic white, POR, 1.64, 99% CI, 1.52–1.77. After controlling for the confounding variables, the racial/ethnic differences in hypertension persisted. Conclusions. Racial/ethnic disparities in hypertension persisted after controlling for potential predictors of hypertension in NHIS, implying the inability of known hypertension risk factors to account for racial/ethnic variability in hypertension in US.

Health literacy challenges in the aging population

PURPOSE

The purpose of this paper is to discuss the impact of low health literacy and discuss interventions to minimize its effect on the elderly population.

CONCLUSION

Low health literacy combined with the physiological changes of aging put the elderly in a vulnerable position. It can negatively affect health behaviors and health outcomes, and can lead to economic burden, not just on the individual but on the society as a whole.

PRACTICE IMPLICATION

Clinicians need to recognize the indicators of low health literacy and utilize the available assessment tools. To improve clinician-patient communication, interventions must be tailored to the patients' literacy level.

The relationship between functional health literacy and adherence to emergency department discharge instructions among Spanish-speaking patients

INTRODUCTION

Adherence to emergency department (ED) discharge instructions among immigrant Spanish-speaking populations in the United States is suboptimal. Our objectives were to: (1) investigate associations between functional health literacy (FHL) and ED discharge instruction adherence in Spanish-speaking populations, and (2) compare the ED adherence rates of Spanish speakersto English speakers.

METHODS

Using a matched cohort design, the FHL of adult native Spanish speakers in a tertiary care ED was assessed using the Test of Functional Health Literacy of Adults in Spanish (TOHFLA-S). Gender-matched and age-matched native English speakers were assessed using TOHFLA. TOFHLA scores range from 1 to 100 with adequate FHL cutoff at 74. Excluded patients were those aged less than 19 years, unwilling, prisoners, institutionalized, extremely ill, with a psychiatric complaint, in receipt of nonspecific instructions for follow-up, or with poor vision. A second interview assessed adherence with follow-up appointments and filling prescriptions.

RESULTS

Fifty matched pairs were enrolled. Spanish speakers were less likely to understand discharge instructions (Spanish speakers, 78%; English speakers, 94%; p < .0001) or to keep follow-up appointments (Spanish speakers, 46%; English speakers, 83%; p <.0001). TOFHLA for Spanish speakers averaged 62 vs 93 for English speakers (p < .0001). FHL was associated with understanding of and adherence to discharge instructions for Spanish speakers. Further, Spanish speakers reported lack of understanding as a primary reason for nonadherence.

CONCLUSION

Spanish-speaking patients were less likely to comply with discharge instructions and scored lower on a test of FHL than English-speaking patients. Poor adherence to ED discharge instructions was associated with lower FHL scores for our Spanish-speaking population. Alternative methods of providing discharge instructions to this population of patients should be explored.

Disparities in the outcomes of lumbar spinal stenosis surgery based on insurance status

STUDY DESIGN

Retrospective cohort study using Thomson Reuter's MarketScan database.

OBJECTIVE

To evaluate the extent to which Medicaid versus commercial insurance status affects outcomes after lumbar stenosis surgery.

SUMMARY OF BACKGROUND DATA

The Affordable Care Act aims to expand health insurance and to help narrow existing health care disparities. Medicaid patients have previously been noted to be at an increased risk for impaired access to health care. Conversely, those with commercial insurance may be subject to overtreatment. We examine the surgical treatment of low back pain as an example that has raised significant public health concerns.

METHODS

A total of 28,462 patients, ages 18 and older, were identified who had undergone laminectomy or fusion for spinal stenosis between 2000 and 2009. Patients were characterized by baseline demographic information, comorbidity burden, and type of insurance (Medicaid vs. commercial insurance). Multivariate analysis was performed comparing the relative effect of insurance status on reoperation rates, timing and type of reoperations, postoperative complications, and total postoperative health resource use.

RESULTS

Medicaid patients had similar reoperation rates to commercially insured patients at 1 year (4.60% vs. 5.42%, P = .38); but had significantly lower reoperation rates at 2 (7.22% vs. 10.30%; adjusted odds ratio [aOR] = 0.661; 95% confidence interval [CI], 0.533-0.820; P = .0002) and more than 2 years (13.92% vs. 16.89%; aOR = 0.722; 95% CI, 0.612-0.851; P <.0001). Medicaid patients were particularly less likely to undergo fusion as a reoperation (aOR = 0.478; 95% CI, 0.377-0.606; P < 0001). Medicaid patients had greater health care resource utilization as measured by hospital days, outpatient services and medications prescribed; however, commercially insured patients had significantly higher overall health utilization costs at 1 and 2 years.

CONCLUSION

There are insurance disparities that affect important surgical outcomes after initial surgery for spinal stenosis. Efforts for national health care reform should include explicit efforts to identify such system factors that will reduce current inequities in care.
