Health literacy among Medicare enrollees in a managed care organization

Chronic kidney disease in the urban poor

BACKGROUND AND OBJECTIVES

In the United States, relatively little is known about clinical outcomes of chronic kidney disease (CKD) in vulnerable populations utilizing public health systems. The primary study objectives were to describe patient characteristics, incident ESRD, and mortality in adults with nondialysis-dependent CKD receiving care in the health care safety net.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Time to ESRD and time to death were examined among a cohort of 15,353 ambulatory adults with nondialysis-dependent CKD from the Community Health Network of San Francisco.

RESULTS

The mean age of the CKD cohort was 59.0 +/- 13.8 years; 50% of the cohort was younger than 60 years and 26% was younger than 50 years. Most (72%) were members of nonwhite racial-ethnic groups, 73% were indigent (annual income <$15,000) and 18% were uninsured. In adjusted analyses, blacks [hazard ratio (95% confidence interval), 4.00 (2.99 to 5.35)], Hispanics [2.20 (1.46 to 3.30)], and Asians/Pacific Islanders [3.84 (2.73 to 5.40)] had higher risks of progression to ESRD than non-Hispanic whites. The higher risk of progression to ESRD among nonwhite compared with white persons with CKD was not explained by lower relative mortality.

CONCLUSIONS

Adults with CKD stages 3 to 5 cared for within an urban public health system were relatively young and predominantly nonwhite-both factors associated with a higher risk of progression to ESRD. These findings call for targeted efforts to assess the burden and progression of CKD within other public and safety-net health systems in this country.

A randomized trial of pictorial versus prose-based medication information pamphlets

OBJECTIVE

The goal of this study was to compare prose and pictorial-based information pamphlets about the medication methotrexate in the domains of free recall, cued recall, comprehension and utility.

METHODS

A single blind, randomized trial of picture versus prose-based information pamphlets including 100 participants aged 18-65 years of age, who had not completed high school, could read English, and had no prior knowledge about methotrexate. Superiority of pamphlet type was assessed using immediate free recall, cued recall and comprehension.

RESULTS

There were no differences between picture and prose pamphlets in free recall, cued recall, and comprehension either immediately or after a 1-week interval. Immediate free recall of important information was 17-26%; free recall fell even lower to 7-16% after 1 week. The pictorial pamphlet was preferred over the prose-based pamphlet.

CONCLUSION

This study found no benefit in free recall, cued recall, or comprehension through the addition of pictograms to a simple prose-based medication pamphlet.

PRACTICE IMPLICATIONS

In order for them to be effective in clinical practice, even simple medication information pamphlets that have been assessed for patients' ability to comprehend them cannot be used as the sole means for conveying important medication-related information to patients.

In search of 'low health literacy': threshold vs. gradient effect of literacy on health status and mortality

Studies have demonstrated significant associations between limited literacy and health outcomes. Yet differences in literacy measurement and the cutoffs used for analysis have made it difficult to fully understand the relationship between literacy and health across the entire spectrum of literacy (i.e., whether the relationship is continuous and graded or whether a threshold exists below which literacy is independently associated with health). To analyze this question, we re-examined the relationship between literacy, baseline physical functioning and mental health, and all-cause mortality for a cohort of 3260 US community-dwelling elderly who were interviewed in 1997 to determine demographics, socioeconomic status, chronic conditions, self-reported physical and mental health (SF-36 subscales), health behaviors, and literacy based upon the Short Test of Functional Health Literacy in Adults (S-TOFHLA). All-cause mortality was determined using data from the US National Death Index through 2003. Seven categories of S-TOFHLA literacy scores were created and used in this analysis instead of the existing three categories identified with the measure. In multivariate analyses, a continuous, graded relationship between literacy and baseline physical functioning was identified. However, participants scoring below the third literacy category had significantly worse mental health compared to the highest literacy category, displaying a notable threshold. Finally, all six literacy categories were significantly associated with greater all-cause mortality risk compared to the highest literacy category, but again there was a marked threshold below the third category at which the adjusted mortality rate significantly increased compared to all other categories. We conclude that the nature of the relationship between literacy and health may vary depending upon the outcome under examination.

Health literacy in the context of HIV treatment: introducing the Brief Estimate of Health Knowledge and Action (BEHKA)-HIV version

A brief, 8-item assessment of HIV treatment knowledge and action was developed and evaluated. Patients with HIV were interviewed in 2001 at infectious disease clinics in Shreveport, LA and Chicago, IL. Analyses on demographics, self-reported medication adherence, and responses to the Rapid Estimate of Adult Literacy in Medicine (REALM) and new, Brief Estimate of Health Knowledge and Action-HIV version (BEHKA-HIV) were performed in 2007. The BEHKA-HIV demonstrated high internal consistency, and construct validity. Lower scores on the BEHKA-HIV were independently associated with poorer rates of HIV medication adherence, scores 4-5 out of 8, AOR 2.6 (95% CI 1.9-3.6), and scores 0-3, AOR 11.4 (95% CI 8.2-15.9), as were the lowest scores on the REALM, AOR 3.3 (95% CI 1.3-8.7). The BEHKA-HIV is a psychometrically sound tool for assessing health knowledge and action regarding HIV treatment, and predicting non-adherence to HIV medications.

The Role of Health Literacy and Written Medicine Information in Nonsteroidal Antiinflammatory Drug Risk Awareness

Background:

Despite widespread use of prescription nonsteroidal antiinflammatory drugs (NSAIDs), patients are commonly unaware of their risks. Pharmacies regularly distribute written medicine information (WMI) describing the risks and benefits of NSAID therapy at the time of dispensing.

Objective:

To clarify the relationship among common sociodemographic factors, education, health literacy, reading of WMI routinefy distributed at pharmacies, and NSAID risk awareness.

Methods:

Generalized linear latent and mixed models (GLLAMM) ordered logistic regression and confirmatory path analysis were used to evaluate multivariable relationships in a cross-sectional dataset of 382 patients in the second phase of the Alabama NSAID Patient Safety Study.

Results:

The majority of the analytical sample was female (72.0%) with 38.7% African American, 38.1% age 65 years or older, and 43.3% reporting at least some college education. Health literacy was positively associated with reading of WMI (p = 0.001) and NSAID risk awareness (p = 0.025), while age was negatively associated with reading WMI (p = 0.001) and NSAID risk awareness (p = 0.005). Medicaid/uninsured status was negatively associated with risk awareness (p = 0.013). Reading of WMI was not associated with NSAID risk awareness (p = 0.659). The final path model demonstrated excellent fit.

Conclusions:

The lack of relationship between reading of WMI and NSAID risk awareness questions the current strategy of distribution of patient-targeted print education materials at pharmacies. To maximize limited resources, future research should identify more effective strategies to deliver risk information to patients and ensure its retention, especially in high-risk groups such as the elderly, the indigent, and those with inadequate health literacy.

Health literacy and communication quality in health care organizations

The relationship between limited health literacy and poor health may be due, in part, to poor communication quality within health care delivery organizations. We explored the relationship between health literacy status and receiving patient-centered communication in clinics and hospitals serving communication-vulnerable patient populations. Thirteen health care organizations nationwide distributed a survey to 5929 patients. All patients completed seven items assessing patient-centered communication. One third also completed three items assessing health literacy. The majority of patients had self-reported health literacy challenges, reporting problems learning about their medical condition because of difficulty understanding written information (53%), a lack of confidence in completing medical forms by themselves (61%), and needing someone to help them read hospital/clinic materials (57%). Logistic regression models showed that, after adjustment for patient demographic characteristics and health care organization type, patients with limited health literacy were 28% to 79% less likely than those with adequate health literacy to report their health care organization "always" provides patient-centered communication across seven communication items. Using a scaled composite of these items, limited health literacy remained associated with lower reported communication quality. These results suggest that improving communication quality in health care organizations might help to address the challenges facing patients with limited health literacy. They also highlight that efforts to address the needs of patients with limited health literacy should be sensitive to the range of communication challenges confronting these patients and their caregivers.

Health literacy and its association with the use of information sources and with barriers to information seeking in clinic-based pregnant women

We investigated health literacy and its association with the use of information sources and with barriers to information seeking in clinic-based pregnant women. The Short Test of Functional Health Literacy in Adults (STOFHLA) was used to measure health literacy in 143 English-speaking low-income pregnant women. About 15% of the participants demonstrated low health literacy. Participants with low health literacy were less likely to use the Internet and more likely to have self-efficacy barriers than participants with high health literacy. Interventions to promote information-seeking skills and Internet access are indicated for women with low health literacy.

Health literacy and the patient with heart failure--implications for patient care and research: a consensus statement of the Heart Failure Society of America

BACKGROUND

Low health literacy compromises patient safety, quality health care, and desired health outcomes. Specifically, low health literacy is associated with decreased knowledge of one's medical condition, poor medication recall, nonadherence to treatment plans, poor self-care behaviors, compromised physical and mental health, greater risk of hospitalization, and increased mortality.

METHODS

The health literacy literature was reviewed for: definitions, scope, risk factors, assessment, impact on health outcomes (cardiovascular disease and heart failure), and interventions. Implications for future research and for clinical practice to address health literacy in heart failure patients were summarized.

RESULTS

General health literacy principles should be applied to patients with heart failure, similar to others with chronic conditions. Clinicians treating patients with heart failure should address health literacy using five steps: recognize the consequences of low health literacy, screen patients at risk, document literacy levels and learning preferences, and integrate effective strategies to enhance patients' understanding into practice.

CONCLUSION

Although the literature specifically addressing low health literacy in patients with heart failure is limited, it is consistent with the larger body of health literacy evidence. Timely recognition of low health literacy combined with tailored interventions should be integrated into clinical practice.

S-TOFHLA in mild Alzheimer's disease and Mild Cognitive Impairment patients as a measure of functional literacy: Preliminary study

The greatest difficulty in diagnosing cognitive loss in our population is the diversity of its education which has a broad spectrum ranging from illiteracy, functional illiteracy and different degrees of literacy, even in those with the same level of schooling.

Developing predictive models of health literacy

INTRODUCTION

Low health literacy (LHL) remains a formidable barrier to improving health care quality and outcomes. Given the lack of precision of single demographic characteristics to predict health literacy, and the administrative burden and inability of existing health literacy measures to estimate health literacy at a population level, LHL is largely unaddressed in public health and clinical practice. To help overcome these limitations, we developed two models to estimate health literacy.

METHODS

We analyzed data from the 2003 National Assessment of Adult Literacy (NAAL), using linear regression to predict mean health literacy scores and probit regression to predict the probability of an individual having 'above basic' proficiency. Predictors included gender, age, race/ethnicity, educational attainment, poverty status, marital status, language spoken in the home, metropolitan statistical area (MSA) and length of time in U.S.

RESULTS

All variables except MSA were statistically significant, with lower educational attainment being the strongest predictor. Our linear regression model and the probit model accounted for about 30% and 21% of the variance in health literacy scores, respectively, nearly twice as much as the variance accounted for by either education or poverty alone.

CONCLUSIONS

Multivariable models permit a more accurate estimation of health literacy than single predictors. Further, such models can be applied to readily available administrative or census data to produce estimates of average health literacy and identify communities that would benefit most from appropriate, targeted interventions in the clinical setting to address poor quality care and outcomes related to LHL.

How numeracy influences risk comprehension and medical decision making

We review the growing literature on health numeracy, the ability to understand and use numerical information, and its relation to cognition, health behaviors, and medical outcomes. Despite the surfeit of health information from commercial and noncommercial sources, national and international surveys show that many people lack basic numerical skills that are essential to maintain their health and make informed medical decisions. Low numeracy distorts perceptions of risks and benefits of screening, reduces medication compliance, impedes access to treatments, impairs risk communication (limiting prevention efforts among the most vulnerable), and, based on the scant research conducted on outcomes, appears to adversely affect medical outcomes. Low numeracy is also associated with greater susceptibility to extraneous factors (i.e., factors that do not change the objective numerical information). That is, low numeracy increases susceptibility to effects of mood or how information is presented (e.g., as frequencies vs. percentages) and to biases in judgment and decision making (e.g., framing and ratio bias effects). Much of this research is not grounded in empirically supported theories of numeracy or mathematical cognition, which are crucial for designing evidence-based policies and interventions that are effective in reducing risk and improving medical decision making. To address this gap, we outline four theoretical approaches (psychophysical, computational, standard dual-process, and fuzzy trace theory), review their implications for numeracy, and point to avenues for future research.

Health literacy and functional health status in Korean older adults

AIMS AND OBJECTIVES

The aim of the study was to investigate the relationships of health literacy to chronic medical conditions and the functional health status among community-dwelling Korean older adults.

BACKGROUND

In the literature, limited health literacy has been reported to have adverse effect on health outcomes. However, the link between health literacy to health status among Korean older adults needs to be clarified.

DESIGN

A cross-sectional survey.

METHODS

A cross-sectional survey of 103 community-dwelling Korean older adults was conducted from June 2007-September 2007. Health literacy was measured using the Korean Functional Health Literacy test and functional health status was measured using the subscales of the Medical Outcomes Study 12-item Short-Form Health Survey.

RESULTS

Individuals with a low health literacy had significantly higher rates of arthritis and hypertension. After adjusting for age, education and income, older individuals with low health literacy had higher limitations in activity and lower subjective health. In a model adjusting for age and income only, older individuals with low health literacy were more likely to report lower levels of physical function and subjective health and higher levels of limitations in activity and pain.

CONCLUSIONS

Among community-dwelling Korean older adults, limited health literacy is associated independently with higher rates of chronic medical conditions and lower subjective health status.

RELEVANCE TO CLINICAL PRACTICE

Nurses are key to providing health education to older adults. The understanding of the relationship of health literacy to health status is essential to develop communication and health education efforts for older adults in nursing practice.

[Health literacy and health status of Korean-Chinese elderly people living in Yanbian, China]

PURPOSE

This descriptive study was done to identify the relationship between health literacy and health status and to provide basic data for developing nursing interventions for Korean-Chinese elders living in Yanbian, China.

METHODS

For data collection, intentional sampling of 300 elders was used. The questionnaire was composed of 5 items based on "Ministry of Health, the People's Republic of China (2008)" to measure health literacy, 33 health status items from the "Korean Health Status Measure for Elderly People" developed by Shin (2002), revised for use in China, and 9 general characteristics. Data were analyzed using SPSS Win 13.0 program.

RESULTS

Total level of health literacy was relatively high (68.7%). Elders had high scores for taking medicines according to doctor's instruction, but lower ones for full comprehension through communication with doctors. Health status was high for emotional, physical, and social function in that order. There were significant differences between general characteristics and health status for gender, age, marital status, education, family, smoking, and alcohol consumption in that order. Results of multiple regression analysis for factors influencing health status showed that self-report health level was the most influential, followed by health literacy, age, gender.

CONCLUSION

Health literacy is the main factor affecting health promotion among minority elders indicating a need to develop health promotion programs for elders who have low health literacy.

The use of illustration to improve older adults' comprehension of health-related information: is it helpful?

OBJECTIVE

To examine whether explanatory illustrations can improve older adults' comprehension of written health information.

METHODS

Six short health-related texts were selected from websites and pamphlets. Young and older adults were randomly assigned to read health-related texts alone or texts accompanied by explanatory illustrations. Eye movements were recorded while reading. Word recognition, text comprehension, and comprehension of the illustrations were assessed after reading.

RESULTS

Older adults performed as well as or better than young adults on the word recognition and text comprehension measures. However, older adults performed less well than young adults on the illustration comprehension measures. Analysis of readers' eye movements showed that older adults spent more time reading illustration-related phrases and fixating on the illustrations than did young adults, yet had poorer comprehension of the illustrations.

CONCLUSION

Older adults might not benefit from text illustrations because illustrations can be difficult to integrate with the text.

PRACTICE IMPLICATIONS

Health practitioners should not assume that illustrations will increase older adults' comprehension of health information.

Readability estimates for commonly used health-related quality of life surveys

PURPOSE

To estimate readability of seven commonly used health-related quality of life instruments: SF-36, HUI, EQ-5D, QWB-SA, HALex, Minnesota Living with Heart Failure Questionnaire (MLHFQ), and the NEI-VFQ-25.

METHODS

The Flesch-Kincaid (F-K) and Flesch Reading Ease (FRE) formulae were used to estimate readability for every item in each measure.

RESULTS

The percentage of items that require more than 5 years of formal schooling according to F-K was 50 for the EQ-5D, 53 for the SF-36, 80 for the VFQ-25, 85 for the QWB-SA, 100 for the HUI, HALex, and the MLHFQ. The percentage of items deemed harder than "easy" according to FRE was 50 for the SF-36, 67 for the EQ-5D, 79 for the QWB-SA, 80 for the VFQ-25, 100 for the HUI, HALex, and the MLHFQ.

CONCLUSIONS

All seven surveys have a substantial number of items with high readability levels that may not be appropriate for the general population.

A randomized trial comparing digital video disc with written delivery of falls prevention education for older patients in hospital

OBJECTIVES

To compare the effectiveness of a digital video disc (DVD) with that of a written workbook delivering falls prevention education to older hospital patients on self-perceived risk of falls, perception of falls epidemiology, knowledge of prevention strategies, and motivation and confidence to engage in self-protective strategies. To compare the effect of receiving either education approach versus no education on patients' perception of falls epidemiology.

DESIGN

Randomized trial (DVD vs workbook) with additional quasi-experimental control group.

SETTINGS

Geriatric, medical, and orthopedic wards in Perth and Brisbane, Australia.

PARTICIPANTS

One hundred (n=51 DVD, n=49 workbook) hospital inpatients aged 60 and older receiving an intervention (mean age 75.3+/-10.1) and 122 in the control group (mean age 79.3+/-8.3).

INTERVENTION

Participants randomly assigned to receive identical educational material on falls prevention delivered on a DVD or in a workbook. Control group received usual care.

MEASUREMENTS

Custom-designed survey addressing elements of the Health Belief Model of health behavior change.

RESULTS

Participants randomized to DVD delivery had a higher self-perceived risk of falling (P=.04) and higher levels of confidence (P=.03) and motivation (P=.04) to engage in self-protective strategies than participants who received the workbook. A higher proportion of participants who received either form of the education provided "desired" responses than of control group participants across all knowledge items (P<.001).

CONCLUSION

Delivery of falls prevention education on a DVD compared to a written workbook is more likely to achieve important changes in parameters likely to affect successful uptake of falls prevention messages in the hospital setting.

Health literacy and cognitive performance in older adults

OBJECTIVES

To study the relationship between health literacy and memory and verbal fluency in older adults.

DESIGN

Cross-sectional cohort.

SETTING

Twenty senior centers and apartment buildings in New York, New York.

PARTICIPANTS

Independently living, English- and Spanish-speaking adults aged 60 and older (N=414).

MEASUREMENTS

Health literacy was measured using the Short Test of Functional Health Literacy in Adults (S-TOFHLA). The associations between S-TOFHLA scores and immediate and delayed recall (Wechsler Memory Scale II), verbal fluency (Animal Naming), and global cognitive function (Mini-Mental State Examination, MMSE) were modeled using multivariable logistic and linear regression.

RESULTS

Health literacy was inadequate in 24.3% of participants. Impairment of immediate recall occurred in 20.4%; delayed recall, 15.0%; verbal fluency, 9.9%; and MMSE, 17.4%. Abnormal cognitive function was strongly associated with inadequate health literacy: immediate recall (adjusted odds ratio (AOR)=3.44, 95% confidence interval (CI)=1.71-6.94, P<.001), delayed recall (AOR=3.48, 95% CI=1.58-7.67, P=.002), and verbal fluency (AOR=3.47, 95% CI=1.44-8.38, P=.006). These associations persisted in subgroups that excluded individuals with normal age-adjusted MMSE scores.

CONCLUSION

Memory and verbal fluency are strongly associated with health literacy, independently of education and health status, even in those with subtle cognitive dysfunction. Reducing the cognitive burden of health information might mitigate the detrimental effects of limited health literacy in older adults. Research that examines the effect of materials modified to older adults' cognitive limitations on health literacy and health outcomes is needed.

Elderly patients' knowledge of drug benefit caps and communication with providers about exceeding caps

OBJECTIVES

Many elderly persons have drug benefits with coverage gaps, such as in Medicare Part D. Because beneficiaries who have such gaps must pay all drug costs, an accurate knowledge of gap thresholds and communication with providers about exceeding caps is important for elderly persons to manage out-of-pocket drug costs.

DESIGN

Cross-sectional survey.

SETTING

Health plan.

PARTICIPANTS

One thousand three hundred eight health plan members aged 65 and older. The study was a 2002 cross-sectional survey of elderly persons with capped drug benefits in a managed care plan in one state. Participants were sampled so that half reached coverage caps and half did not.

METHODS

Participants reported cap levels, communication with providers about exceeding caps, and decreased medication use due to cost.

RESULTS

Of the 1,308 participants (65.4%response rate), 68.6%did not know their correct cap level. Rates were similar in those who exceeded caps (66.2%), reported difficulty paying for medications (63.9%), or decreased medication use (66%). For participants who exceeded caps, 59.1% did not know beforehand that they were close to exceeding caps and 50.2% did not tell providers afterward. In multivariate analyses accounting for demographics and health, the oldest participants (> or =85 vs 65-74) were at greater risk for not knowing cap levels (odds ratio (OR)=2.0, 95% confidence interval (CI)=1.2-3.4) and not telling providers about exceeding caps (OR=2.2, 95% CI=1.1-4.5).

CONCLUSIONS

Elderly patients often did not know correct cap levels and did not tell providers about exceeding caps. Providers, plans, and policymakers should actively assess and improve Medicare beneficiaries' knowledge of Part D coverage gaps.

The relationship between health literacy and knowledge improvement after a multimedia type 2 diabetes education program

OBJECTIVE

Multimedia diabetes education programs (MDEP) have the potential to improve communication and education of those with low health literacy. We examined the effect of a MDEP targeted to patients with low literacy on knowledge and assessed the association between literacy and knowledge improvement.

METHODS

We showed the MDEP to 190 patients recruited from clinics at a federally qualified health center and an academic health center. We measured diabetes knowledge before and after viewing the MDEP.

RESULTS

Seventy-nine percent of patients had adequate literacy, 13% marginal, and 8% inadequate literacy. Patients across all literacy levels had significant increases in knowledge scores after viewing the MDEP (p-value<0.001). Patients with inadequate literacy learned significantly less after the MDEP (adjusted beta-coefficient=-2.3, SE=0.70) compared to those with adequate literacy.

CONCLUSIONS

A MDEP designed for those with low literacy significantly increased diabetes knowledge across literacy levels. However, the MDEP did not overcome the learning gap between patients with low and high literacy.

PRACTICE IMPLICATIONS

A literacy appropriate MDEP may be an effective way to teach patients about diabetes. Combining the MDEP with other education methods may improve comprehension and learning among those with low literacy. Research is needed to identify which characteristics of low-literate patients influence the ability to learn health information. Identifying these factors and incorporating solutions into a diabetes education intervention may help bridge the learning gap related to literacy status.

Latinos and HIV/AIDS: examining factors related to disparity and identifying opportunities for psychosocial intervention research

Latinos maintain an AIDS case rate more than 3 times higher than whites, a greater rate of progression to AIDS, and a higher rate of HIV/AIDS-related deaths. Three broad areas are reviewed related to these disparities: (1) relevant demographic, socioeconomic, and socio-cultural factors among Latinos; (2) drug abuse and mental health problems in Latinos relevant to HIV/AIDS outcomes; and (3) opportunities for psychosocial intervention. Latinos living with HIV are a rapidly growing group, are more severely impacted by HIV than whites, and confront unique challenges in coping with HIV/AIDS. A body of research suggests that depression, substance abuse, treatment adherence, health literacy, and access to healthcare may be fruitful targets for intervention research in this population. Though limited, the current literature suggests that psychosocial interventions that target these factors could help reduce HIV/AIDS disparities between Latinos and whites and could have important public health value.

Performance of a Brazilian population on the test of functional health literacy in adults

OBJECTIVE

To analyze the scoring obtained by an instrument, which evaluates the ability to read and understand items in the health care setting, according to education and age.

METHODS

The short version of the Test of Functional Health Literacy in Adults was administered to 312 healthy participants of different ages and years of schooling. The study was conducted between 2006 and 2007, in the city of São Paulo, Southeastern Brazil. The test includes actual materials such as pill bottles and appointment slips and measures reading comprehension, assessing the ability to read and correctly pronounce a list of words and understand both prose passages and numerical information. Pearson partial correlations and a multiple regression model were used to verify the association between its scores and education and age.

RESULTS

The mean age of the sample was 47.3 years(sd=16.8) and the mean education was 9.7 years(sd=5; range: 1 - 17). A total of 32.4% of the sample showed literacy/numeracy deficits, scoring in the inadequate and marginal functional health literacy ranges. Among the elderly (65 years or older) this rate increased to 51.6%. There was a positive correlation between schooling and scores (r=0.74; p<0.01) and a negative correlation between age and the scores (r=-0.259; p<0.01). The correlation between the scores and age was not significant when the effects of education were held constant (rp=-0.031, p=0.584). A significant association (B=3.877, Beta =0.733; p<0.001) was found between schooling and scores. Age was not a significant predictor in this model (B=-0.035, Beta=-0.22; p=0.584).

CONCLUSIONS

The short version of the Test of Functional Health Literacy in Adults was a suitable tool to assess health literacy in the study population. The high number of individuals classified as functional illiterates in this test highlights the importance of special assistance to help them properly understand directions for healthcare.

Functional health literacy among primary health-care patients: data from the Belgrade pilot study

BACKGROUND

Over the last decade, health literacy has become a vibrant area of research. Our objective was to evaluate health literacy and its association with socio-demographic variables, self-perception of health and the presence of chronic conditions in primary health-care patients.

METHODS

A cross-sectional study among 120 patients was conducted in two primary health-care centers. The test of functional health literacy in adults, a 50-item reading comprehension and 17-item numerical ability test (score, 0-100) were administered. Chi-square test and logistic regression analyses were applied.

RESULTS

Inadequate and marginal health literacy existed in 43 participants (41.0%), and adequate health literacy was present in 62 participants (59.0%). Functional health literacy was significantly different by location, gender, age, marital status, employment, education, material status, self-perception of health and presence of chronic conditions. Based on the multivariate analysis, health literacy was significantly associated with the participant's age (odds ratio [OR], 4.86; 95% confidence interval [CI], 2.41-9.80; P = 0.000), level of education (OR, 4.48; 95% CI, 1.73-11.57; P = 0.002) and chronic conditions (OR, 1.90; 95% CI, 1.16-3.11; P = 0.010).

CONCLUSION

These results provide evidence that limitations in functional health literacy are widespread among primary health-care patients and encourage efforts for further monitoring. Low health literacy may impair a patient's understanding of health messages and limit their ability to attend to their medical problems.

Addressing asthma health disparities: a multilevel challenge

Substantial research has documented pervasive disparities in the prevalence, severity, and morbidity of asthma among minority populations compared with non-Latino white subjects. The underlying causes of these disparities are not well understood, and as a result, the leverage points to address them remain unclear. A multilevel framework for integrating research in asthma health disparities is proposed to advance both future research and clinical practice. The components of the proposed model include health care policies and regulations, operation of the health care system, provider/clinician-level factors, social/environmental factors, and individual/family attitudes and behaviors. The body of research suggests that asthma disparities have multiple, complex, and interrelated sources. Disparities occur when individual, environmental, health system, and provider factors interact with one another over time. Given that the causes of asthma disparities are complex and multilevel, clinical strategies to address these disparities must therefore be comparably multilevel and target many aspects of asthma care. Several strategies that could be applied in clinical settings to reduce asthma disparities are described, including the need for routine assessment of the patient's beliefs, financial barriers to disease management, and health literacy and the provision of cultural competence training and communication skills to health care provider groups.

A health literacy assessment of the epilepsy.com website

Current healthcare guidelines identify low health literacy as a major barrier to optimal health communication. Health literacy is defined as the degree to which individuals can obtain, process and understand basic health information and services needed to make appropriate health decisions. An estimated 90 million people in the U.S. have marginal health literacy. The Institute of Medicine and the U.S. Department of Education recommend that health related information be written at the 6th-8th grade level to address low health literacy. Epidemiological studies demonstrate that persons with epilepsy have significantly lower educational attainment and lower incomes placing them at risk for low health literacy and limited Internet access. While Internet users tend to have higher educational attainment, previous research indicates even good readers prefer simpler rather than more complex medical information. Health educational content that could be printed and given to patients addresses an important need in clinical epilepsy care. Previous reviews of health websites found they exceed recommended readability levels. Two online programs were used to assess the reading level of 1327 web pages on the www.epilepsy.com website using established readability formulas. Based on the Flesch Reading Ease assessment, only 3% of epilepsy.com web pages are written for a 6th grade reading level or below. If 8th grade level or below is used as the standard, only 15% are adequate. Recommendations and examples are provided for improving the readability of epilepsy-specific health education content.

Health literacy and the role of the speech-language pathologist

PURPOSE

This article reviews concepts of health literacy and discusses the role of speech-language pathologists in improving the health literacy of individuals with and without communication disorders.

METHOD

A literature review was completed of health literacy definitions, concepts, and health literacy assessment and intervention studies with various populations. A literature review was also conducted regarding health literacy or related studies in the field of speech-language pathology.

CONCLUSION

There is a paucity of information available on health literacy within the field of speech-language pathology. Suggestions are offered regarding increasing health literacy research and intervention by speech-language pathologists.

Lack of comprehension of common prostate cancer terms in an underserved population

PURPOSE

To assess the comprehension of common medical terms used in prostate cancer in patient education materials to obtain informed consent, and to measure outcomes after prostate cancer treatment. We address this issue among underserved, African-American men because of the increased cancer incidence and mortality observed in this population.

PATIENTS AND METHODS

We reviewed patient education materials and prostate-specific quality-of-life instruments to identify technical terms describing sexual, urinary, and bowel function. Understanding of these terms was assessed in face-to-face interviews of 105, mostly African-American men, age > or = 40, from two low-income clinics. Comprehension was evaluated using semiqualitative methods coded by two independent investigators. Demographics were collected and literacy was measured.

RESULTS

Fewer than 50% of patients understood the terms "erection" or "impotent." Only 5% of patients understood the term "incontinence" and 25% understood the term "bowel habits." More patients recognized word roots than related terms or compound words (eg, "rectum" v "rectal urgency," "intercourse" v "vaginal intercourse"). Comprehension of terms from all domains was statistically significantly correlated with reading level (P < .001). Median literacy level was fourth to sixth grade. Prostate cancer knowledge was poor. Many patients had difficulty locating key anatomic structures.

CONCLUSION

Limited comprehension of prostate cancer terms and low literacy create barriers to obtaining informed consent for treatment and to measuring prostate cancer outcomes accurately in our study population. In addition, the level of prostate cancer knowledge was poor. These results highlight the need for prostate cancer education efforts and outcomes measurements that consider literacy and use nonmedical language.

Older adults place lower value on choice relative to young adults

Choice is highly valued in modern society, from the supermarket to the hospital; however, it remains unknown whether older and younger adults place the same value on increased choice. The current investigation tested whether 53 older (M age = 75.44 years) versus 53 younger adults (M age = 19.58 years) placed lower value on increased choice by examining the monetary amounts they were willing to pay for increased prescription drug coverage options--important given the recently implemented Medicare prescription drug program. Results indicate that older adults placed lower value on increasing choice sets relative to younger adults, who placed progressively higher value on increasingly larger choice sets. These results are discussed regarding their implications for theory and policy.

Patients' perspectives of the doctor-patient relationship and information giving across a range of literacy levels

OBJECTIVE

This study explored the patient's experience of the doctor-patient relationship and information giving in health care. The views of patients with a range of literacy levels were examined.

METHOD

321 patients at an in-patient cardiology unit provided the sample. The Health Literacy (HL) of participants was assessed using the Rapid Estimate of Adult Literacy in Medicine (REALM). All participants (low and adequate HL) were then asked open ended questions about their experiences of communication with healthcare professionals. The qualitative data underwent a thematic analysis.

RESULTS

22% of the patients interviewed were found to have a low level of literacy as indicated by the REALM. Many patients felt that health information should be given in simpler language. Patients frequently stated that they either did not read information leaflets or were confused or worried by them. They described the importance of the doctor-patient relationship and the need to build up trust. These views were expressed by patients with adequate HL as well as patients with low HL.

CONCLUSION

Many patients irrespective of their HL skills, feel unable to access, understand and utilize health information.

PRACTICE IMPLICATIONS

If patients are to be actively engaged in achieving and maintaining good health, healthcare professionals must improve their communication skills and ensure that health information is clear and easy to access.

Application of the Cloze Procedure to Evaluate Comprehension and Demonstrate Rewriting of Pharmacy Educational Materials

Background:

Written materials are commonly used to communicate pharmacy-relevant information to patients. However, they are often composed at a level that limits comprehension, mitigating a well-intended effect.

Objective:

To (1) use the cloze procedure (a test designed to assess reading comprehension) to evaluate an individual's understanding of a pharmacy-relevant educational pamphlet; (2) compare results of the cloze procedure with the reading comprehension component of the Short Test of Functional Health Literacy in Adults (S-TOFHLA); and (3) use results to demonstrate rewriting of the educational pamphlet.

Methods:

The cloze procedure was applied to a pharmacy-relevant educational pamphlet describing safe medication practices. A total of 162 subjects were recruited from university faculty, staff, and students; a local adult literacy center; and community senior centers. Subjects completed a background interview, the S-TOFHLA. and cloze procedure for the pharmacy-relevant educational pamphlet. S-TOFHLA and cloze procedure scores were described and compared. Cloze procedure responses were used to demonstrate revision of the pamphlet RESULTS: Of the 154 subjects analyzed, mean ± SD age was 56.5 ± 20.4 years. Subjects were predominantly white (93.5%), female (71.4%). and college graduates (42.2%). Mean score on the S-TOFHLA was 92.1%. A majority (95.5%, 147/154) of subjects demonstrated adequate functional health literacy. In contrast, mean score on the cloze procedure was 53.3%. Internal consistencies of the S-TOFHLA and the cloze procedure were 0.92 and 0.90, respectively. Scores on the cloze procedure and the S-TOFHLA were highly correlated (r = 0.71, p < 0.001), Performance on the cloze procedure indicated that 55.2% of subjects required supplemental teaching.

Conclusions:

In this highly educated, health-literate sample, a majority did not understand the pharmacy-relevant educational pamphlet despite adequate performance on a standard measure of health literacy. The cloze procedure can be used to assess comprehension of educational materials, solicit feedback from intended users, and guide the revision of educational materials.

Health literacy in COPD

If patients are to participate fully in their care and in the management of a long-term condition such as chronic obstructive pulmonary disease, good communication is essential. However, not all patients are able to use the written word and we need to be aware of the size of this problem and its implications for the way in which we give information and conduct medical consultations. The impact of health literacy on outcomes can be considerable and improvements can be made by being aware of the problem, offering information in several different forms, and by reinforcing the spoken word with pictorial images.

Health literacy and kidney disease: toward a new line of research

Health literacy has been recognized as an important public health issue over the past decade. Low health literacy is a widespread problem in the general population, affecting over 90 million Americans. A growing body of research has demonstrated the association between low health literacy and worse health outcomes in a variety of chronic conditions. Despite the increasing prevalence of chronic kidney disease (CKD) and the considerable interest in health literacy, there has been limited research examining the role of health literacy in individuals at all stages of CKD. This article examines the role of health literacy in kidney disease by reviewing early research on the topic, providing a conceptual model of the relationship between health literacy and health outcomes, and highlighting potential areas for future research on health literacy in CKD.

Assessment of pictographs developed through a participatory design process using an online survey tool

Background

Inpatient discharge instructions are a mandatory requirement of the Centers for Medicare and Medicaid Services and Joint Commission on Accreditation of Healthcare Organizations. The instructions include all the information relevant to post-discharge patient care. Prior studies show that patients often cannot fully understand or remember all the instructions. To address this issue, we have previously conducted a pilot study in which pictographs were created through a participatory design process to facilitate the comprehension and recall of discharge instructions.

Objective

The main objective of this study was to verify the individual effectiveness of pictographs created through a participatory design process.

Methods

In this study, we included 20 pictographs developed by our group and 20 pictographs developed by the Robert Wood Johnson Foundation as a reference baseline for pictographic recognition. To assess whether the participants could recognize the meaning of the pictographs, we designed an asymmetrical pictograph–text label-linking test. Data collection lasted for 7 days after the email invitation. A total of 44 people accessed the survey site. We excluded 7 participants who completed less than 50% of the survey. A total of 719 answers from 37 participants were analyzed.

Results

The analysis showed that the participants recognized the pictographs developed in-house significantly better than those included in the study as a baseline (P< .001). This trend was true regardless of the participant’s gender, age, and education level. The results also revealed that there is a large variance in the quality of the pictographs developed using the same design process—the recognition rate ranged from below 50% to above 90%.

Conclusions

This study confirmed that the majority of the pictographs developed in a participatory design process involving a small number of nurses and consumers were recognizable by a larger number of consumers. The variance in recognition rates suggests that pictographs should be assessed individually before being evaluated within the context of an application.

A randomized controlled trial of interventions to enhance patient-physician partnership, patient adherence and high blood pressure control among ethnic minorities and poor persons: study protocol NCT00123045

BACKGROUND

Disparities in health and healthcare are extensively documented across clinical conditions, settings, and dimensions of healthcare quality. In particular, studies show that ethnic minorities and persons with low socioeconomic status receive poorer quality of interpersonal or patient-centered care than whites and persons with higher socioeconomic status. Strong evidence links patient-centered care to improvements in patient adherence and health outcomes; therefore, interventions that enhance this dimension of care are promising strategies to improve adherence and overcome disparities in outcomes for ethnic minorities and poor persons.

OBJECTIVE

This paper describes the design of the Patient-Physician Partnership (Triple P) Study. The goal of the study is to compare the relative effectiveness of the patient and physician intensive interventions, separately, and in combination with one another, with the effectiveness of minimal interventions. The main hypothesis is that patients in the intensive intervention groups will have better adherence to appointments, medication, and lifestyle recommendations at three and twelve months than patients in minimal intervention groups. The study also examines other process and outcome measures, including patient-physician communication behaviors, patient ratings of care, health service utilization, and blood pressure control.

METHODS

A total of 50 primary care physicians and 279 of their ethnic minority or poor patients with hypertension were recruited into a randomized controlled trial with a two by two factorial design. The study used a patient-centered, culturally tailored, education and activation intervention for patients with active follow-up delivered by a community health worker in the clinic. It also included a computerized, self-study communication skills training program for physicians, delivered via an interactive CD-ROM, with tailored feedback to address their individual communication skills needs.

CONCLUSION

The Triple P study will provide new knowledge about how to improve patient adherence, quality of care, and cardiovascular outcomes, as well as how to reduce disparities in care and outcomes of ethnic minority and poor persons with hypertension.

Promoting health communication between the community-dwelling well-elderly and pharmacists: the Ask Me 3 program

OBJECTIVE

To describe readiness to use clear health communication principles with a pharmacist before and after participating in the Ask Me 3 (What is my main problem?, What do I need to do?, Why is it important for me to do this?) program.

DESIGN

Modified, separate-sample, pretest-posttest study.

SETTING

Senior centers in Polk County, IA, between March 2006 and February 2007.

PARTICIPANTS

106 community-dwelling well-elderly.

INTERVENTION

Information on demographic characteristics, regularity of health care and medication use, health literacy level, and a measurement of multidimensional health locus of control were collected from participants, who were then were randomly allocated to one of three assessment subgroups: (1) pretest-posttest, (2) pretest only, and (3) posttest only during each of 12 Ask Me 3 program educational sessions.

MAIN OUTCOME MEASURE

Readiness to use the seven principles of clear health communication described in the Ask Me 3 program.

RESULTS

Participants were predominantly women and white, had a high school education or higher, had a yearly income of $25,000 or less, and had a mean age of 75.1 years. A majority reported good to excellent health status and visited their physician two or more times per year. All took medications regularly for a medical problem. A minority had inadequate to marginal health literacy. Before the Ask Me 3 program, a majority reported planning to or actively asking their pharmacist (1) for help with questions about their medications (88.2%), (2) to explain how to take their medication (82.6%), (3) to describe the main problem for which their medication is being prescribed (78.6%), and (4) to describe what can happen if they don't take their medication (74.3%). Approximately one-half of participants (55.2%) made a list of health or medication concerns to tell their pharmacist. A minority brought a list of current medications (47.8%) or brought a friend or family member to help when visiting their pharmacist (27.9%). A significantly higher proportion of participants reported planning to or actively bringing a list of current medications when visiting the pharmacist (P < or = 0.025) after participating in the Ask Me 3 program. Increases were not statistically significant for the remaining principles.

CONCLUSION

The Ask Me 3 program is a practical tool that creates awareness and reinforces principles of clear health communication. The Ask Me 3 program should be evaluated in diverse pharmacy and health care settings with patients at high risk for poor health communication.

Comprehension of Health-related Written Materials by Older Adults

This study examined how Flesch Reading Ease and text cohesion affect older adults' comprehension of common health texts. All older adults benefited when high Flesh Reading Ease was combined with high cohesion. Older adults with small working memories had more difficulty understanding texts high in Flesch Reading Ease. Additionally, older adults with low verbal ability or older than 77 years of age had difficulty understanding texts high in text cohesion but low in Flesch Reading Ease. These results imply that writers must increase Flesch Reading Ease without disrupting text cohesion to ensure comprehension of health-related texts.

Implementing an innovative consent form: the PREDICT experience

BACKGROUND

In the setting of coronary angiography, generic consent forms permit highly variable communication between patients and physicians. Even with the existence of multiple risk models, clinicians have been unable to readily access them and thus provide patients with vague estimations regarding risks of the procedure.

METHODS

We created a web-based vehicle, PREDICT, for embedding patient-specific estimates of risk from validated multivariable models into individualized consent documents at the point-of-care. Beginning August 2006, outpatients undergoing coronary angiography at the Mid America Heart Institute received individualized consent documents generated by PREDICT. In February 2007 this approach was expanded to all patients undergoing coronary angiography within the four Kansas City hospitals of the Saint Luke's Health System. Qualitative research methods were used to identify the implementation challenges and successes with incorporating PREDICT-enhanced consent documents into routine clinical care from multiple perspectives: administration, information systems, nurses, physicians, and patients.

RESULTS

Most clinicians found usefulness in the tool (providing clarity and educational value for patients) and satisfaction with the altered processes of care, although a few cardiologists cited delayed patient flow and excessive patient questions. The responses from administration and patients were uniformly positive. The key barrier was related to informatics.

CONCLUSION

This preliminary experience suggests that successful change in clinical processes and organizational culture can be accomplished through multidisciplinary collaboration. A randomized trial of PREDICT consent, leveraging the accumulated knowledge from this first experience, is needed to further evaluate its impact on medical decision-making, patient compliance, and clinical outcomes.

Health literacy among Spanish-speaking patients in the emergency department

STUDY OBJECTIVE

Health literacy influences a patient's ability to read and understand labels on medicine containers, appointment slips, informed-consent documents and medical instructions--all of which are considered basic health documents that a patient encounters in healthcare settings. Previous research suggests Spanish-speaking patients have low levels of health literacy. This study compares the functional health literacy (FHL) of Spanish- and English-speaking adult patients in a suburban emergency department (ED).

METHODS

Through a prospective, matched cohort design, Spanish-speaking adult patients and pediatric guardians presenting to the ED were matched with English-speaking patients by age, gender and treatment area. Demographic information, including total years of school completed and self-assessed reading ability, was collected. The Test of Functional Health Literacy in Adults (TOFHLA) was administered in the subject's primary language. A score of <60 indicated inadequate FHL, 60-74 marginally adequate FHL, and >74 adequate literacy.

RESULTS

Eighty-six matched pairs were enrolled. The median age was 30.5 years, and 56% were male. Spanish speakers averaged a TOFHLA score of 59.72, and English speakers 90.78. Only 7% of English speakers had less-than-adequate FHL compared to 74% of Spanish speakers. The average years of school completed were 10.59 (7.95 Spanish; 13.19 English), and 55% of English speakers reported "excellent" reading ability compared to 13% of Spanish speakers. Last grade completed (p=0.004) and self-assessed reading ability (p=0.0007) are predictors of TOFHLA scores. Those subjects who completed less than the eighth grade had inadequate FHL.

CONCLUSIONS

The majority of Spanish-speaking subjects have less-than-adequate FHL. Self-reported reading ability and years of school completed appear to predict FHL and may be clinically useful. Due to the disproportionately low level of health literacy among Spanish-speaking patients demonstrated in this and previous studies, future efforts should focus on developing programs that improve health literacy by providing this population with oral translations and pictorial and video instructions.

Health literacy and access to kidney transplantation

BACKGROUND AND OBJECTIVES

Few studies have examined health literacy in patients with end stage kidney disease. We hypothesized that inadequate health literacy in a hemodialysis population is common and is associated with poorer access to kidney transplant wait-lists.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We enrolled 62 Black and White maintenance hemodialysis patients aged 18 to 75. We measured health literacy using the short form Test of Functional Health Literacy in Adults. Our primary outcomes were (1) time from dialysis start date to referral date for kidney transplant evaluation and (2) time from referral date to date placed on kidney transplant wait-list. We used Cox proportional hazard models to examine the association between health literacy (adequate versus inadequate) and our outcomes after controlling for demographics and co-morbid conditions.

RESULTS

Roughly one third (32.3%) of participants had inadequate health literacy. Forty-seven (75.8%) of participants were referred for transplant evaluation. Among those referred, 40 (85.1%) were wait-listed. Participants with inadequate health literacy had 78% lower hazard of referral for transplant evaluation than those with adequate health literacy (adjusted hazard ratio [AHR] 0.22; 95% confidence interval 0.08, 0.60; P = 0.003). The hazard ratio of being wait-listed by health literacy was not statistically different (AHR 0.80, 95% CI, 0.39, 1.61), P = 0.5).

CONCLUSIONS

Inadequate health literacy is common in our hemodialysis patient population and is associated with a lower hazard of referral for transplant evaluation. Strategies to reduce the impact of health literacy on the kidney transplant process should be explored.

Numeracy and communication with patients: they are counting on us

Patient-centered interactive communication between physicians and patients is recommended to improve the quality of medical care. Numerical concepts are important components of such exchanges and include arithmetic and use of percentages, as well as higher level tasks like estimation, probability, problem-solving, and risk assessment--the basis of preventive medicine. Difficulty with numerical concepts may impede communication. The current evidence on prevalence, measurement, and outcomes related to numeracy is presented, along with a summary of best practices for communication of numerical information. This information is integrated into a hierarchical model of mathematical concepts and skills, which can guide clinicians toward numerical communication that is easier to use with patients.

Neighborhood poverty and kidney transplantation among US Asians and Pacific Islanders with end-stage renal disease

The degree to which low transplant rates among Asians and Pacific Islanders in the United States are confounded by poverty and reduced access to care is unknown. We examined the relationship between neighborhood poverty and kidney transplant rates among 22 152 patients initiating dialysis during 1995-2003 within 1800 ZIP codes in California, Hawaii and the US-Pacific Islands. Asians and whites on dialysis were distributed across the spectrum of poverty, while Pacific Islanders were clustered in the poorest areas. Overall, worsening neighborhood poverty was associated with lower relative rates of transplant (adjusted HR [95% CI] for areas with > or =20% vs. <5% residents living in poverty, 0.41 [0.32-0.53], p < 0.001). At every level of poverty, Asians and Pacific Islanders experienced lower transplant rates compared with whites. The degree of disparity increased with worsening neighborhood poverty (adjusted HR [95% CI] for Asians-Pacific Islanders vs. whites, 0.64 [0.51-0.80], p < 0.001 for areas with <5% and 0.30 [0.21-0.44], p < 0.001 for areas with > or =20% residents living in poverty; race-poverty level interaction, p = 0.039). High levels of neighborhood poverty are associated with lower transplant rates among Asians and Pacific Islanders compared with whites. Our findings call for studies to identify cultural and local barriers to transplant among Asians and Pacific Islanders, particularly those residing in resource-poor neighborhoods.
