Health literacy among Medicare enrollees in a managed care organization

Designing Written Medication Instructions: Effective Ways to Help Older Adults Self-Medicate

One of the goals of Healthy People 2010 is for 95% of patients who are ordered medication to receive written medication instructions. The declining physical condition often associated with advanced age, lower literacy levels, and education among members of the current elderly cohorts, and increasingly complex medication regimes for chronic illness affect the ability of many older adults to learn. This article addresses Geragogy, the art and science of helping older adults learn, complimentary theories of learning, and examples of how they can be used to guide the construction of appropriate written medication instructions for older adults.

The impact of low health literacy on the medical costs of Medicare managed care enrollees

PURPOSE

To examine the impact of low health literacy on medical care use and costs.

METHODS

The study sample consisted of 3260 noninstitutionalized elderly persons enrolling in a Medicare managed care plan in 1997 in Cleveland, Ohio; Houston, Texas; South Florida; and Tampa, Florida. Health literacy--the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions--was measured using the Short Test of Functional Health Literacy in Adults. We used a 2-part regression model to examine the association between health literacy and medical costs, adjusting for age, sex, race/ethnicity, education, income, alcohol and tobacco consumption, and comorbid conditions. Results are presented as mean differences (with 95% confidence intervals [CI]) between the inadequate and adequate groups and, separately, the marginal and adequate groups.

RESULTS

When compared to those with adequate health literacy, emergency room costs were significantly higher ($108; 95% CI: $62 to $154; P <0.0001) among those with inadequate health literacy, while differences in total ($1551; 95% CI: -$166 to $3267; P = 0.08) and inpatient ($1543; 95% CI: -$89 to $3175; P = 0.06) costs were marginally significant. Total costs were higher in the marginal health literacy group, but the difference was not significant ($596; 95% CI: -$1437 to $2630; P = 0.57).

CONCLUSIONS

Persons with inadequate health literacy incur higher medical costs and use an inefficient mix of services.

Understanding health literacy: an expanded model

A long and yet unfinished history of investigating how individual capabilities and social processes explain or predict health indicates that poor education, low literacy, poor health and early death are strongly linked around the world. However, the complexity of those relationships is not fully understood. In this article, we propose an expanded model of health literacy characterized by four domains: fundamental literacy (reading, writing, speaking and numeracy), science literacy, civic literacy and cultural literacy. To explore the utility of this model, we examine selected pieces of the public discourse about terrorism and bioterrorism that dominated the mass media during the anthrax threat in the United States during 2001. We conclude that this model of health literacy is useful to analyze health communication, to aid in constructing more understandable and appropriate health communication, and ultimately can lead to the development of a new measure to assess health literacy skills in individuals.

Performance of the English and Spanish S-TOFHLA among publicly insured Medicaid and Medicare patients

The objective of this study was to analyze the psychometric properties of the English and Spanish S-TOFHLA for three patient populations of interest. Despite being widely used, little is written about psychometric properties of the S-TOFHLA, particularly the Spanish version. Participants were Medicaid and Medicare patients: 936 non-Hispanic and 368 Hispanic patients completed the English S-TOFHLA; 1066 Hispanics completed the Spanish S-TOFHLA. Validity of both versions of the S-TOFHLA was supported by strong positive relationships with education and inverse relationships with age. Significant differences between scores for men and women remained after adjusting for level of education. Score differences occurred across numerous items. More research is needed on the S-TOFHLA and other health literacy instruments to determine why women score differently than men. Variability in literacy skills within subgroups of patients highlights the importance of healthcare providers being sensitive to patients' literacy levels in both spoken and written communications.

Evaluation à l’occasion de leur hospitalisation de la qualité de l’anticoagulation orale chez des patients traités par antivitamines K

BACKGROUND

Excessive or insufficient anticoagulation therapy and its associated risks are of major concern in patients receiving oral anticoagulants. Such complications can be avoided by more rigorous management.

OBJECTIVE

The aim of our study was to evaluate those patients receiving oral anticoagulant therapy on the day of hospitalisation among all patients admitted to the Amiens University Hospital during 14 days.

METHODS

We evaluated the quality of management of the treatment in these patients, taking into account the international normalised ratio (INR), as well as important parameters such as the summary of the product characteristics (SPCs), drug interactions, and the level of knowledge of anticoagulant treatment by the patients themselves (questionnaire).

RESULTS

Of the 2498 adult patients hospitalised, 86 patients (30 female and 56 male aged between 26 and 95 years [mean 70 years]) treated with oral anticoagulants were evaluated. At admission, seven cases of haemorrhage and two of thrombosis were registered. One drug-related death occurred and one patient had sequelae. In 17.5% of the cases, the prescription was not fully in agreement with the SPCs. This percentage increased to 67% for patients with adverse effects. In 41% of the patients, the INR was outside the therapeutic zone. The dosage regimen was too complex in 11% of cases. Six drug combinations were labelled as not recommended in the SPCs: four with aspirin <3 g/day and two with nonsteroidal anti-inflammatory drugs. The analysis of questionnaires showed that patients had insufficient knowledge of their treatment: only 16 of 66 knew the risks resulting from overdose or an insufficient dose of the anticoagulant drug, 25 of 66 knew that anticoagulation induced by the treatment can be influenced by food, 10 of 66 knew the therapeutic range of the INR appropriate for them, and 8 of 66 knew that intramuscular injections were prohibited.

CONCLUSIONS

These data confirm that anticoagulant treatment needs to be more strictly controlled in order to avoid adverse effects. Risks are probably underestimated by physicians. Information given to patients seems insufficient or unsuitable (too complex).

To know or not to know: the case of communication by and with older adult Russians diagnosed with cancer

This paper describes the ways in which group identifications and stereotypes can inform our understanding of cancer treatment and survivorship, as well as the more general social processes surrounding the communicative experiences of older adult Russians diagnosed with cancer, by providing a theoretical essay (with some modest illustrative data) to shed light on salient cross-cultural health and identity issues. Utilizing an approach grounded in social identity theory, it describes the ways in which understanding primary identities associated with large social collectives such as cultural groups, secondary identities associated with health behaviors and tertiary identities associated with a cancer diagnosis can help explain certain cancer-related social processes. Subtle cultural differences in approaches to health care, particularly with older adult populations, are likely influenced by assumptions embedded in their economic, social, and political systems.

The prevalence of limited health literacy

OBJECTIVE

To systematically review U.S. studies examining the prevalence of limited health literacy and to synthesize these findings by evaluating demographic associations in pooled analyses.

DESIGN

We searched the literature for the period 1963 through January 2004 and identified 2,132 references related to a set of specified search terms. Of the 134 articles and published abstracts retrieved, 85 met inclusion criteria, which were 1) conducted in the United States with > or =25 adults, 2) addressed a hypothesis related to health care, 3) identified a measurement instrument, and 4) presented primary data. The authors extracted data to compare studies by population, methods, and results.

MAIN RESULTS

The 85 studies reviewed include data on 31,129 subjects, and report a prevalence of low health literacy between 0% and 68%. Pooled analyses of these data reveal that the weighted prevalence of low health literacy was 26% (95% confidence interval [CI], 22% to 29%) and of marginal health literacy was 20% (95% CI, 16% to 23%). Most studies used either the Rapid Estimate of Adult Literacy in Medicine (REALM) or versions of the Test of Functional Health Literacy in Adults (TOFHLA). The prevalence of low health literacy was not associated with gender (P=.38) or measurement instrument (P=.23) but was associated with level of education (P=.02), ethnicity (P=.0003), and age (P=.004).

CONCLUSIONS

A pooled analysis of published reports on health literacy cannot provide a nationally representative prevalence estimate. This systematic review exhibits that limited health literacy, as depicted in the medical literature, is prevalent and is consistently associated with education, ethnicity, and age. It is essential to simplify health services and improve health education. Such changes have the potential to improve the health of Americans and address the health disparities that exist today.

Complexity in caring for an ageing heart failure population: concomitant chronic conditions and age related impairments

The complexity of caring for the ageing heart failure (HF) population is further complicated by concomitant chronic conditions (i.e., polypharmacy, depression), age related impairments (i.e., hearing, visual and cognitive impairments, impairments in activities of daily living (ADL/IADL), and other issues (e.g., health illiteracy, lack of social support). This paper provides an overview of these risk factors, outlines how they individually and in interplay endanger favourable outcome by putting patients at risk for poor self-management. Moreover, suggestions are made on how these issues could be addressed and integrated in heart failure management by applying gerontological care principles in caring for the ageing heart failure population.

Insurance knowledge and decision-making practices among Medicare beneficiaries and their caregivers

BACKGROUND

The complexity of health plans and the Medicare program may require some beneficiaries to seek help when making health insurance decisions. However, there has been little research examining the Medicare-related knowledge and information gathering of beneficiaries who receive decision-making help and those who assist them.

OBJECTIVES

We sought to compare the Medicare knowledge and information-gathering of beneficiaries who receive help with insurance decisions or their proxy respondents with beneficiaries who make their own decisions.

RESEARCH DESIGN

Data were drawn from the 2000 Medicare Current Beneficiary Survey (MCBS), which includes a nationally representative sample of noninstitutionalized Medicare beneficiaries.

SUBJECTS

We included a total of 11,978 beneficiaries and 1401 proxies who completed the MCBS.

MEASURES

Measures were items and indices from the MCBS measuring the Medicare education campaign goals of access, awareness, and use of information sources, understanding of Medicare, and confidence in decision-making.

RESULTS

Beneficiaries who receive help with health insurance decisions have lower knowledge of the Medicare program and are less likely to be aware of and use information sources than beneficiaries who make their own decisions. With few exceptions, proxy respondents had similar levels of access and knowledge as beneficiaries who make their own insurance decisions.

CONCLUSIONS

Beneficiaries who receive help with their insurance decisions may be a particularly vulnerable population. They may have limited Medicare knowledge and not be aware of the resources that could help them.

Tipping the Scales: The Effect of Literacy on Obese Patients’ Knowledge and Readiness to Lose Weight

OBJECTIVES

The purpose of this study was to determine the association between the literacy level of overweight/obese patients and their weight-loss knowledge, attitudes, and readiness.

METHODS

Structured patient interviews and a literacy screening instrument were administered in two primary care clinics at a university-based public hospital.

RESULTS

A convenience sample of 210 overweight or obese adult outpatients (body mass index > or =25 kg/m2 or > or =30 kg/m2, respectively) were enrolled. Mean respondent age was 52 years; 74% were female, and 76% were black. Two thirds of patients read below a 9th grade level. Half of patients across all literacy levels reported currently attempting weight loss. There was a significant relation between literacy level and weight-loss knowledge, attitudes, and readiness (P < 0.05).

CONCLUSIONS

Patients with low literacy were significantly less likely to understand the adverse health consequences of obesity and the need to lose weight and to report being ready to lose weight. Patient education and counseling for weight loss should be tailored for patients with low literacy skills.

Literacy and health outcomes: a systematic review of the literature

OBJECTIVE

To review the relationship between literacy and health outcomes.

DATA SOURCES

We searched MEDLINE, Cumulative Index to Nursing and Allied Health (CINAHL), Educational Resources Information Center (ERIC), Public Affairs Information Service (PAIS), Industrial and Labor Relations Review (ILLR), PsychInfo, and Ageline from 1980 to 2003.

STUDY SELECTION

We included observational studies that reported original data, measured literacy with any valid instrument, and measured one or more health outcomes. Two abstractors reviewed each study for inclusion and resolved disagreements by discussion.

DATA EXTRACTION

One reviewer abstracted data from each article into an evidence table; the second reviewer checked each entry. The whole study team reconciled disagreements about information in evidence tables. Both data extractors independently completed an 11-item quality scale for each article; scores were averaged to give a final measure of article quality.

DATA SYNTHESIS

We reviewed 3,015 titles and abstracts and pulled 684 articles for full review; 73 articles met inclusion criteria and, of those, 44 addressed the questions of this report. Patients with low literacy had poorer health outcomes, including knowledge, intermediate disease markers, measures of morbidity, general health status, and use of health resources. Patients with low literacy were generally 1.5 to 3 times more likely to experience a given poor outcome. The average quality of the articles was fair to good. Most studies were cross-sectional in design; many failed to address adequately confounding and the use of multiple comparisons.

CONCLUSIONS

Low literacy is associated with several adverse health outcomes. Future research, using more rigorous methods, will better define these relationships and guide developers of new interventions.

Over-the-counter analgesics in older adults: a call for improved labelling and consumer education

The use of analgesics increases with age and on any given day 20-30% of older adults take an analgesic medication. Over-the-counter (OTC) analgesics are generally well tolerated and effective when taken for brief periods of time and at recommended dosages. However, their long-term use, use at inappropriately high doses, or use by persons with contraindications may result in adverse effects, including gastrointestinal haemorrhage, cardiovascular toxicity, renal toxicity and hepatotoxicity. Many OTC drugs are also available through a prescription, for a broader range of indications and for longer durations of use and wider dose ranges, under the assumption that healthcare providers will help patients make safe choices about analgesics. Safe and effective use of medications is one of the greatest challenges faced by healthcare providers in medicine. More than 60% of people cannot identify the active ingredient in their brand of pain reliever. Additionally, about 40% of Americans believe that OTC drugs are too weak to cause any real harm. As a result of a recent US FDA policy, the conversion of prescription to OTC medications will result in a 50% increase of OTC medications. To reduce the risks of potential adverse effects from OTC drug therapy in older adults, we propose that the use of analgesics will be enhanced through the use of patient and healthcare provider education, as well as improved labelling of OTC analgesics. Improved labelling of OTC analgesics may help consumers distinguish common analgesic ingredients in a wide variety of preparations and facilitate informed decisions concerning the use of OTC drugs.

Intended message versus message received in hypothetical physician risk communications: exploring the gap

We examined the risk perception that is derived from hypothetical physician risk communications. Subjects (n= 217) completed a questionnaire on the Web for $3. Subjects were presented with four hypothetical cancer risk scenarios that included a physician risk communication in one of three risk communication formats: verbal only, verbal plus numeric probability as a percent, and verbal plus numeric probability as a fraction. In each scenario, subjects were asked to imagine themselves as the patient described and to state their perceived personal susceptibility to the cancer (i.e., risk perception) on a 0 to 100 scale, as well as responses to other measures. Subjects' risk perceptions were highly variable, spanning nearly the entire probability scale for each scenario, and the degree of variation was only slightly less in the risk communication formats in which a numeric statement of risk was provided. Subjects were more likely to overestimate than underestimate their risk relative to the stated risk in the numeric versions, and overestimation was associated with the belief that the physician minimized the risk so they wouldn't worry, innumeracy, and worry, as well as decisions about testing for the cancer. These results demonstrate significant gaps between the intended message and the message received in physician risk communications. Implications for medical decisions, patient distress, and future research are discussed.

Compliance in contact allergy with focus on cosmetic labelling: a qualitative research project

Elimination of the allergen is an effective remedy in allergic contact dermatitis. When contact allergy to a preservative is diagnosed, the patient is instructed to read the labelling of contents and to avoid the use of products containing the allergens. The present study, using qualitative research methods, was performed to examine how socially different groups of patients handle everyday life with allergic contact dermatitis caused by preservatives in consumer products. 8 women were interviewed about reading the ingredient labelling on cosmetic products. Observational studies were carried out as well. The study illustrates that the patients experienced problems when trying to read the labelling of contents. The problems were related to social status and ranged from not being able to read the chemical names of the preservatives to doubting the accuracy of the ingredient labelling. The study indicates that non-compliance with instructions on reading the ingredient labelling is not only a question of patients' lack of knowledge, but also the result of patients not possessing the resources necessary to act in accordance with the medical instructions. The present study is, to our knowledge, the first to apply qualitative research methods to contact dermatitis. The study points out interesting observations about social status and resources in relation to compliance. Further research on this area is necessary to expose the extent of the problem.

Colorectal cancer screening knowledge, attitudes, and beliefs among veterans: does literacy make a difference?

PURPOSE

To evaluate whether lower literacy is associated with poorer knowledge and more negative attitudes and beliefs toward colorectal cancer screening among veterans without recent colorectal cancer screening.

PATIENTS AND METHODS

Three hundred seventy-seven male veterans, age 50 years and older, who had not undergone recent colorectal cancer screening, were surveyed about their knowledge, attitudes, and beliefs regarding colorectal cancer screening. Patients' literacy was assessed with the Rapid Estimate of Adult Literacy in Medicine, an individually administered screening test for reading.

RESULTS

Thirty-six percent of the 377 men had an eighth grade literacy level or higher. Men with lower literacy were 3.5 times as likely not to have heard about colorectal cancer (8.8% v 2.5%; P =.006), 1.5 times as likely not to know about screening tests (58.4% v 40.9%; P =.0001), and were more likely to have negative attitudes about fecal occult blood testing (FOBT), but not about flexible sigmoidoscopy. Specifically, men with lower literacy skills were two times as likely to be worried that FOBT was messy (26.7% v 13.3%; P =.008), 1.5 times as likely to feel that FOBT was inconvenient (28.7% v 18%; P =.05), and four times as likely to state they would not use an FOBT kit even if their physician recommended it (17.9% v 4.0%; P =.02).

CONCLUSION

Limited literacy may be an overlooked barrier in colorectal cancer screening among veterans.

The impact of low health literacy on surgical practice

BACKGROUND

We sought to determine the prevalence of low health literacy (LHL) among patients in a preoperative clinic, the characteristics associated with LHL, and the association between LHL and adherence to preoperative instructions.

METHODS

We conducted a cohort study and interviewed patients at a VA preoperative clinic. We administered a health literacy test and collected sociodemographic information. When patients returned for their scheduled surgical procedures, adherence to preoperative instructions was assessed.

RESULTS

Of 332 participants, 12% (n = 40) had LHL. Low health literacy was more prevalent among older adults (more than 65 years) compared with those under age 65. Patients with LHL were more likely to be nonadherent to preoperative medication instructions (odds ratio = 1.9; 95% confidence interval: 0.8 to 4.8), but this was of borderline statistical significance.

CONCLUSIONS

Low health literacy was common among older patients and appeared to be associated with lower adherence to preoperative medication instructions.

Numeracy and the shortcomings of utility assessment in head and neck cancer patients

BACKGROUND

Because survival differences between surgical and nonsurgical treatment for head and neck cancer (HNC) are hard to detect, increasing focus has been placed on quality of life (QOL) differences after treatment. Utility assessment provides insight into QOL. Evidence suggests that a patient's comfort with numerical concepts ("numeracy") may influence utility measures. We hypothesize that patients who are nonnumerate provide inconsistent utility data in QOL studies.

METHODS

New HNC (n = 18) patients were recruited to participate. Patients completed a numeracy questionnaire, a utility assessment, and a global QOL questionnaire. Higher scores reflect better function. Interviewers rated the functional level of each patient. For both numerate and nonnumerate patients, utility scores were compared with global QOL (good vs poor) and observer-rated function.

RESULTS

Half of the patients were numerate. Numerate patients who rated their QOL as good had significantly higher utility scores than did patients with poor global QOL (0.95 vs 0.43, p =.03). In contrast, nonnumerate patients with good QOL had lower utility scores than did patients with poor QOL (0.45 vs 0.77, NS). Utility scores for numerate patients correlated well with observer-rated function (r = 0.41 to r = 0.57), whereas those of nonnumerate patients did not (r = -0.16 to r = 0.06).

CONCLUSIONS

QOL evaluation through utility assessment may provide inaccurate and contradictory data about patient functioning for nonnumerate patients. This may confound QOL assessment when interpreting utility data.

Literacy and Numeracy Skills and Anticoagulation Control

BACKGROUND

The ability to use printed material to function in society (literacy) and to handle basic numerical concepts (numeracy) may have implications in patients' ability to follow dosing schedules. We examined literacy and numeracy skills among patients on warfarin and explored their association with anticoagulation control.

METHODS AND RESULTS

Patients older than 50 years attending two anticoagulation management units were prospectively enrolled. We measured literacy, numeracy, and international normalized ratio (INR). During a 3-month follow-up period, we calculated the variability of the INR and the amount of time a patient's INR was within his or her therapeutic range, variables associated with bleeding and effectiveness. Among 143 patients, only 75 (52.4%) were able to read health-related words at the eighth grade level or less. Patients' self-reported grade completed was higher than the measured literacy grade level (kappa = 0.21). While 79.0% had completed at least eight grades, only 47.6% had a score at that grade level. Sixty-nine patients answered none or correctly answered fewer than two of the six numeracy questions (48.3%). The INR variability was higher among patients with lower literacy (P = 0.009) and lower numeracy skills (P = 0.004). The time in range was similar among patients at different literacy levels (P = 0.9). Patients with lower numeracy level spent more time above their therapeutic range (P = 0.04) and had a trend of less time spent in range (P = 0.10).

CONCLUSIONS

Low literacy was prevalent among study patients taking warfarin. Low literacy and numeracy were associated with measures of poor anticoagulation control.

Cardiopulmonary Resuscitation Programs Revisited: Results of a Community Study Among Older African Americans

Early cardiopulmonary resuscitation (CPR) performed by a layperson and prompt defibrillation in the field are critical links in the chain of survival of out-of-hospital sudden cardiac arrest. It has been suggested that minorities, women, and elderly persons are often left out of CPR training programs. To examine knowledge and attitudes toward CPR and automatic external defibrillation among African Americans, the author and colleagues conducted home interviews in a population sample of 425 older men and women in Miami-Dade County, FL. It was found that 25% of the participants did not know what CPR was. Only 18% of men and 28% of women had ever taken CPR classes. Mean age the time of CPR training was for men 36 years and for women 46 years. About 74% of all subjects did not know whom to contact for CPR training, and fewer than 5% knew about the American Heart Association Heartsaver Program (including automatic external defibrillation performed by laypersons). The majority of participants suggested churches or community organizations as organizers of CPR training. This study shows that there is a major need for improving knowledge and intensifying CPR training programs among older African Americans. Community organizations and churches may play a critical role in reaching this goal.

Health literacy, social support, and health: a research agenda

Amid increased concerns about the adverse consequences of low health literacy, it remains unclear how health literacy affects health status and health service utilization. Moreover, studies have shown significant variation in individual adaptation to health literacy problems. This article proposes research hypotheses to address two questions: (1) What are the causal pathways or intermediate steps that link low health literacy to poor health status and high utilization of expensive services such as hospitalization and emergency care? (2) What impact does social support have on the relationships between health literacy and health service utilization? Empirical studies of health literacy are reviewed to indicate the limitations of current literature and to highlight the importance of the proposed research agenda. In particular, we note the individualistic premise of current literature in which individuals are treated as isolated and passive actors. Thus, low health literacy is considered simply as an individual trait independent of support and resources in an individual's social environment. To remedy this, research needs to take into account social support that people can draw on when problems arise due to their health literacy limitations. Examination of the proposed agenda will make two main contributions. First, we will gain a better understanding of the causal effects of health literacy and identify missing links in the delivery of care for patients with low health literacy. Second, if social support buffers the adverse effects of low health literacy, more effective interventions can be designed to address differences in individuals' social support system in addition to individual differences in reading and comprehension. More targeted and more cost-efficient efforts could also be taken to identify and reach those who not only have low health literacy but also lack the resources and support to bridge the unmet literacy demands of their health conditions.

The relationship between literacy and glycemic control in a diabetes disease-management program

PURPOSE

This study examined the role of literacy in patients with poorly controlled diabetes who were participating in a diabetes management program that included low-literacy-oriented interventions.

METHODS

A before-after analysis was performed of a pharmacist-led diabetes management program for 159 patients with type 2 diabetes and poor glycemic control (hemoglobin A1c [A1C] > or = 8.0%). Clinic-based pharmacists offered one-to-one education and medication management for these patients using techniques that did not require high literacy. Literacy was measured by the Rapid Estimate of Adult Literacy in Medicine (REALM) test and dichotomized at the 6th-grade level. The A1C values were collected prior to enrollment, at enrollment, and approximately 6 months after enrollment.

RESULTS

Of the 111 patients with follow-up data, 55% had literacy levels at the 6th-grade level or below. Lower literacy was more common among African Americans, older patients, and patients who required medication assistance. There was no significant relationship between literacy status and A1C prior to enrollment or at enrollment. Over the 6-month study period, patients with low and high literacy had similar improvements in A1C.

CONCLUSIONS

This diabetes care program, which used individualized teaching with low-literacy techniques, significantly improved A1C values independent of literacy status.

Low literacy Chinese patients: how are they affected and how do they cope with health matters? A qualitative study

BACKGROUND

Low literacy is common in Hong Kong and China, especially among the females and the elderly. These are often the patients with the greatest health care needs. However little is known about how low literacy affects the ability of patients to obtain adequate medical care and comply with the recommendations of health professionals.

METHODS

Qualitative study of subjects' opinions using semi-structured group and individual interviews. Thirty-six participants took part in 6 group and 9 individual interviews.

RESULTS

Participants' opinions towards low literacy were explored in the interviews. They expressed diverse views on how they perceived low literacy. Some thought they were handicapped by it but others felt it was not a problem. Age, gender, chronic illnesses and their attitudes towards self were found to be major factors affecting their perception. Despite their low literacy, some had their specific ways to overcome the difficulties, for example, drawing symbols to help with the timing of taking the medications. Most of them felt better explanation by the health care workers was most important.

CONCLUSIONS

It is highly relevant for health care workers to be aware of the low literacy status of their patients and to explain information so that patients understand it.

The effect of format modifications and reading comprehension on recall of informed consent information by low-income parents: a comparison of print, video, and computer-based presentations

A randomized trial comparing the amount of knowledge orally recalled from four different presentations of the same consent information was conducted in a non-clinic sample of 233 low-income parents who displayed a range of reading comprehension skill. The study simulated recruitment of children into one of two actual studies underway at another location: one involved high risk to participants, the other did not. Use of a non-clinic sample controlled for prior knowledge of the conditions, and avoiding discussion of the information further assured that differences in recalled information could be attributed more confidently to the format itself. The formats included the original written forms, enhanced print (simpler language, topic headings, pictures), narrated videotapes, and self-paced PowerPoint presentations via laptop computer with bulleted print information, pictures, and narration. No format-related differences in recalled information were found in the full sample but for the 124 individuals with reading comprehension scores at or below the 8th grade level, the enhanced print version tended to be more effective than either the original form or the video. Across all formats, more information was recalled about the low-risk study. The findings emphasize the necessity for clinicians and researchers to verify understanding of consent information, especially when there is risk of reduced literacy skill. Reliance on video to convey information in preference to well-done print media appeared questionable.

Reporting pesticide assessment results to farmworker families: development, implementation, and evaluation of a risk communication strategy

The collection of environmental samples presents a responsibility to return information to the affected participants. Explaining complex and often ambiguous scientific information to a lay audience is a challenge. As shown by environmental justice research, this audience frequently has limited formal education, increasing the challenge for researchers to explain the data collected, the risk indicated by the findings, and action the affected community should take. In this study we describe the development and implementation of a risk communication strategy for environmental pesticide samples collected in the homes of Latino/a migrant and seasonal farmworkers in a community-based participatory research project. The communication strategy was developed with community input and was based on face-to-face meetings with members of participating households. Using visual displays of data effectively conveyed information about individual household contamination and placed it in the context of community findings. The lack of national reference data and definitive standards for action necessitated a simplified risk message. We review the strengths and weaknesses of such an approach and suggest areas for future research in risk communication to communities affected by environmental health risks.

Health literacy and use of outpatient physician services by Medicare managed care enrollees

OBJECTIVE

To determine whether inadequate functional health literacy adversely affects use of physician outpatient services.

DESIGN

Cohort study.

SETTING

Community.

PARTICIPANTS

New Medicare managed care enrollees age 65 or older in 4 U.S. cities (N = 3,260).

MEASUREMENTS AND MAIN RESULTS

We measured functional health literacy using the Short Test of Functional Health Literacy in Adults. Administrative data were used to determine the time to first physician visit and the total number of visits during the 12 months after enrollment. The time until first visit, the proportion without any visit, and adjusted mean visits during the year after enrollment were unrelated to health literacy in crude and multivariate analyses. Participants with inadequate and marginal health literacy were more likely to have an emergency department (ED) visit than those with adequate health literacy (30.4%, 27.6%, and 21.8%, respectively; P =.01 and P <.001, respectively). In multivariate analysis, the adjusted relative risk of having 2 or more ED visits was 1.44 (95% confidence interval, 1.01 to 2.02) for enrollees with marginal health literacy and 1.34 (1.00 to 1.79) for those with inadequate health literacy compared to participants with adequate health literacy.

CONCLUSIONS

Inadequate health literacy was not independently associated with the mean number of visits or the time to a first visit. This suggests that inadequate literacy is not a major barrier to accessing outpatient health care. Nevertheless, the higher rates of ED use by persons with low literacy may be caused by real or perceived barriers to using their usual source of outpatient care.

Functional health literacy and the quality of physician-patient communication among diabetes patients

While patients with poor functional health literacy (FHL) have difficulties reading and comprehending written medical instructions, it is not known whether these patients also experience problems with other modes of communication, such as face-to-face encounters with primary care physicians. We enrolled 408 English- and Spanish-speaking diabetes patients to examine whether patients with inadequate FHL report worse communication than patients with adequate FHL. We assessed patients' experiences of communication using sub-scales from the Interpersonal Processes of Care in Diverse Populations instrument. In multivariate models, patients with inadequate FHL, compared to patients with adequate FHL, were more likely to report worse communication in the domains of general clarity (adjusted odds ratio [AOR] 6.29, P<0.01), explanation of condition (AOR 4.85, P=0.03), and explanation of processes of care (AOR 2.70, p=0.03). Poor FHL appears to be a marker for oral communication problems, particularly in the technical, explanatory domains of clinician-patient dialogue. Research is needed to identify strategies to improve communication for this group of patients.

Literacy in primary care populations: is it a problem?

BACKGROUND

Almost half of Canadians experience difficulty using print media, according to the 1994 International Adult Literacy Survey. Our objectives were to estimate the prevalence of low-literacy patients in our practice, to determine whether reading grade level is associated with self-perceived health status in primary care, and to evaluate the reading difficulty of commonly used patient education pamphlets.

METHODS

We surveyed a random sample of 229 patients aged 18 to 85 years presenting for scheduled and walk-in care. Main outcome measures were reading ability as estimated by word decoding skill with the validated Rapid Estimate of Adult Literacy in Medicine (REALM) and self-perceived health status using COOP/WONCA functional health measures. We assessed the reading difficulty of 120 commonly used patient education pamphlets using the Simple Measure of Gobbledygook (SMOG) formula.

RESULTS

The prevalence of low-literate patients was 9%. Poor reading ability in English was most likely among patients under 45 years of age not having completed high school, and among those whose maternal language was neither English nor French (immigrants). REALM scores and self-perceived health were weakly correlated but not significant statistically. The mean reading grade level of pamphlets was grade 11.5 (SD: 1.5). Seventy-eight percent of pamphlets required at least a high school reading level.

CONCLUSION

Literacy levels were higher than expected in our patient population; this finding may be due to the rapid assessment tool used, which may have underestimated the difficulty of using print media. Clearly, the vast majority of commonly used patient education materials would not meet the needs of low-literate patients, who may be more likely to experience poorer health. Providers need to be sensitive to the reading limitations of patients and patient education materials should be written at a lower reading level.

Health literacy and knowledge of chronic disease

We sought to examine the relationship between health literacy and knowledge of disease among patients with a chronic disease. A total of 653 new Medicare enrollees aged 65 years or older who had at least one chronic disease (115 asthma, 266 diabetes, 166 congestive heart failure, 214 hypertension), completed both the in-person and telephone survey. Health literacy measured by the short test of functional health literacy in adults (S-TOFHLA) and demographic information were collected during the in-person survey. Knowledge of disease was assessed by questions based on key elements in educational materials during a telephone survey. Overall, 24% of patients had inadequate and 12% had marginal health literacy skills. Respondents with inadequate health literacy knew significantly less about their disease than those with adequate literacy. Multivariate analysis indicated that health literacy was independently related to disease knowledge. There are many opportunities to improve patients' knowledge of their chronic disease(s), and efforts need to consider their health literacy skills.

Quality of Life in elderly patients with cancer

The incidence of most types of cancers is age-dependent and the progressive ageing is rapidly increasing the number of elderly people who need treatment for cancer. Elderly patients present peculiar characteristics that make the choice of the correct treatment more difficult and these patients are often undertreated. Moreover, elderly patients are largely underrepresented in cancer treatment trials, and this makes the experimental evidence on this topic even weaker. Health-related Quality of Life (QOL) has been considered as one of the hard end-points for clinical cancer research, and treatment of elderly cancer patients represents a typical situation where its assessment can be particularly useful, because the expected toxicity of treatment could be relevant in the discussion of the treatment choice. However, QOL assessment in the elderly is complicated by several unresolved methodological problems (higher frequency of illiteracy, worse compliance with the questionnaires, concomitant diseases, use of instruments not validated in the aged population). Conduct of clinical trials dedicated to elderly patients is now encouraged but there are few published studies. Advanced non-small-cell lung cancer is one of the fields with the largest amount of research on QOL in elderly patients. The ELVIS study demonstrated the efficacy of single-agent chemotherapy, both in terms of QOL and of survival. The MILES study, in which combination chemotherapy was not superior than single agents, showed that baseline QOL is a strong prognostic indicator in these patients. QOL of patients with breast cancer has been another important field in clinical research over the last decades, and interest on this topic in elderly patients is growing, from loco-regional to palliative treatment. In conclusion, some steps have been done in clinical cancer research dedicated to elderly patients, and the role of QOL assessment in this setting is important. However, many methodological problems must be resolved, in order to obtain reliable and useful results. A QOL assessment could also be useful for elderly patients in clinical practice, where it could improve patient-clinician communication: a wider application of properly selected instruments should be recommended.

Health literacy: a policy challenge for advancing high-quality health care

Health literacy, at the intersection of health and education, involves more than reading ability. Studies of health literacy abilities show that many Americans with the greatest health care needs have the least ability to comprehend information required to navigate and function in the U.S. health care system. This paper defines health literacy as an important policy issue and offers strategies for creating a health-literate America.

Physician-older patient communication about cancer

Cancer is frequently a disease of older individuals. Communication between physicians and older patients about cancer prevention, screening, diagnosis, treatment and care is complicated by a variety of factors including patients' beliefs, perceptions, and knowledge about cancer. In addition, other older patient factors such as possible sensory deficits, cognitive impairment, functional limitations and accompaniment by significant others to the medical encounter influence communication. Physicians' attitudes about aging may also affect recommendations for cancer screening, treatment regiments and care of older cancer patients. To understand communication as a complex, multidimensional human enterprise requires knowledge of older patients' lived experience of cancer and their need for honest and compassionate care. Research findings on physician-older patient communication about cancer need to be translated into medical education, training and practice to improve the care of the older cancer patient.

Culturally competent healthcare systems. A systematic review

Culturally competent healthcare systems-those that provide culturally and linguistically appropriate services-have the potential to reduce racial and ethnic health disparities. When clients do not understand what their healthcare providers are telling them, and providers either do not speak the client's language or are insensitive to cultural differences, the quality of health care can be compromised. We reviewed five interventions to improve cultural competence in healthcare systems-programs to recruit and retain staff members who reflect the cultural diversity of the community served, use of interpreter services or bilingual providers for clients with limited English proficiency, cultural competency training for healthcare providers, use of linguistically and culturally appropriate health education materials, and culturally specific healthcare settings. We could not determine the effectiveness of any of these interventions, because there were either too few comparative studies, or studies did not examine the outcome measures evaluated in this review: client satisfaction with care, improvements in health status, and inappropriate racial or ethnic differences in use of health services or in received and recommended treatment.

What matters to seriously ill older persons making end-of-life treatment decisions?: A qualitative study

BACKGROUND

Several methods exist to elicit end-of-life treatment preferences. However, little work has been done to elicit from patients themselves the aspects of treatment decision-making most important to them when making end-of-life treatment decisions.

METHODS

Participants consisted of 23 patients, 60 years of age and older with a primary diagnosis of congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), or cancer identified by their physicians as having a limited life expectancy. They took part in in-depth semistructured interviews and focus groups in which they were asked to discuss how they had made previous decisions about the treatment of their illness and/or would think about making future decisions. Transcripts were analyzed qualitatively using the constant comparative method.

RESULTS

There were three major influences on treatment preferences: treatment burden, treatment outcome, and the likelihood of the outcome. Treatment burden was bearable if the outcome of treatment was desirable, but participants were less willing to endure the burden for more marginal outcomes. Certain outcomes were so unacceptable that they determined preference regardless of burden. However, some participants revealed that their willingness to tolerate these adverse outcomes may increase as their illness progresses. Although participants generally believed that physicians know with certainty the outcomes of treatment, most understood the concept of uncertainty, and the likelihood of a given outcome influenced their preferences.

CONCLUSIONS

A patient-centered approach to advance care planning needs to incorporate a consideration of both treatment burdens and treatment outcomes, including the likelihood of these outcomes. Patients' valuations of these outcomes may change over time.

Readability of ocular medication inserts

OBJECTIVE

To determine the readability of ocular medication inserts and whether they are an appropriate source of medication information for patients.

MATERIALS AND METHODS

The Flesch-Kincaid and SMOG readability formulas were used to calculate the readability of 10 common glaucoma medication inserts (Alphagan, Azopt, Betoptic, Betimolol, Cosopt, Optipranolol, Rescula, Trusopt, Timoptic, and Xalatan) and 6 widely used nonglaucoma medication inserts (Alrex, Lotemax, Ocuflox, Patanol, Pred Forte, and Zaditor).

RESULTS

The 10 glaucoma medication inserts surveyed required an average overall grade level of 12.9 +/- 0.6 by the Flesch-Kincaid Index and of 13.5 +/- 0.6 by the SMOG formula. The 6 nonglaucoma medication inserts had an overall grade level of 11.1 +/- 0.6 by the Flesch-Kincaid Index and of 11.7 +/- 0.9 by the SMOG formula. All medications reviewed were above the eighth-grade level recommended by the Flesch-Kincaid Index for public materials.

CONCLUSIONS

Ocular medication inserts are too complex to be an adequate source of medication information for the average American adult. This study highlights the need for improving communication and education regarding patients' medications.

Social identity and health: an intergroup communication approach to cancer

This article describes the ways in which group identifications and stereotypes can inform our understanding of cancer prevention and treatment as well as more general social processes surrounding the experience of cancer. From a perspective grounded in social identity theory, we describe the ways in which understanding primary identities (i.e., those associated with large social collectives such as cultural groups), secondary identities (i.e., those associated with health behaviors), and tertiary identities (i.e., those associated with cancer) can help explain certain cancer-related social processes. We forward a series of propositions to stimulate further research on this topic.

Readability of printed patient information for epileptic patients

BACKGROUND

Written information can be a valuable tool in patient education. Studies evaluating written information for various disease states have frequently demonstrated that the majority of literature is written at a readability level that exceeds that of the average patient, and it has been recommended that written communications for adult patients should be provided at a fifth-grade level or lower.

OBJECTIVE

To assess the readability of printed patient information available to patients with epilepsy.

METHODS

Samples of written patient information (n = 101) were obtained from various sources. The information was classified based on source, content, and intended audience, and readability was assessed using the Flesch Reading Ease Score (FRES) and Flesch-Kincaid Grade Level (FKGL) score.

RESULTS

The mean FRES and FKGL score for all samples were 50.2 and 9.4, respectively. Significant differences were observed in both the FRES and FKGL score of material obtained from different sources; however, no differences were observed when material was analyzed according to content. The mean FRES and FKGL score for materials intended for adults were 49.6 and 9.5, respectively. In comparison, mean FRES and FKGL scores for materials intended for children/adolescents were 78.9 and 5.3, respectively.

CONCLUSIONS

The majority of information tested was written at a level that exceeds the reading ability of many patients. The information intended for children is actually written at the appropriate level for an adult. Efforts should be taken to develop written teaching tools that target low-level readers, especially for a disease state that affects many children.

Population-based osteoporosis education for older women

With an increased focus on wellness and health promotion, there is a need for community-based strategies to complement traditional strategies aimed at improving individual and aggregate health. An educational program on the prevention, diagnosis, and treatment of osteoporosis was provided for 188 women age 60 and older in three different community settings: churches, retirement homes, and senior citizen centers. The major purposes of the study were to determine whether a community-based program might (a) contribute to older women's knowledge about osteoporosis and (b) promote their intent to use this knowledge. Each participant completed a demographic profile, the Osteoporosis Risk Checklist, and the Osteoporosis Knowledge Questionnaire (OKQ), with the OKQ serving as a pre- and post-test. Before post-testing, a 30-min educational program was provided. Differences among the three groups were risk factors, prior knowledge about osteoporosis, and knowledge at the completion of the program. A majority of the clients indicated an intent to increase calcium in their diet, discuss osteoporosis with their health care provider, check their home environment for safety/falls, and discuss what they had learned with others. Nurses need to plan educational programs in all settings to teach older clients about the risk factors, prevention, diagnosis, and treatment of osteoporosis.

Knowledge and self-efficacy of community health nurses concerning interactions of prescription medicines with over-the-counter agents and alcohol

Knowledge and self-efficacy concerning interactions of prescription medications with over-the-counter (OTC) agents were assessed in community health nurses. Three convenience samples of community nurses were recruited to complete the instruments. The first was a sample of 20 experienced nurses working for a local visiting nurse agency (VNARNs). The second was a sample of 20 bachelor of science in nursing (BSN) students (graduate nurses [GNs]) completing their final nursing rotation with the VNARNs. The third was a sample of 31 nurses enrolled in a graduate program training nurses for advanced practice (APRNs). There were no significant differences in overall mean self-efficacy scores among the groups of community health nurses. The mean scores indicated moderate self-efficacy about prescription-OTC interactions. Post-hoc analyses determined VNARNs had significantly greater knowledge scores than APRNs. Overall mean self-efficacy was not correlated with mean knowledge scores. Inspection of the knowledge item responses revealed nine general misconceptions about OTC medications held by many community nurses in the sample. The data can guide the development of continuing education programs about prescription-OTC interactions aimed at community health nurses.

Functional health literacy and the risk of hospital admission among Medicare managed care enrollees

OBJECTIVES

This study analyzed whether inadequate functional health literacy is an independent risk factor for hospital admission.

METHODS

We studied a prospective cohort of 3260 Medicare managed care enrollees.

RESULTS

Of the participants, 29.5% were hospitalized. The crude relative risk (RR) of hospitalization was higher for individuals with inadequate literacy (n = 800; RR = 1.43; 95% confidence interval [CI] = 1.24, 1.65) and marginal literacy (n = 366; RR = 1.33; 95% CI = 1.09, 1.61) than for those with adequate literacy (n = 2094). In multivariate analysis, the adjusted relative risk of hospital admission was 1.29 (95% CI = 1.07, 1.55) for individuals with inadequate literacy and 1.21 (95% CI = 0.97, 1.50) for those with marginal literacy.

CONCLUSIONS

Inadequate literacy was an independent risk factor for hospital admission among elderly managed care enrollees.

Designing and evaluating interventions to eliminate racial and ethnic disparities in health care

A large number of factors contribute to racial and ethnic disparities in health status. Health care professionals, researchers, and policymakers have believed for some time that access to care is the centerpiece in the elimination of these health disparities. The Institute of Medicine's (IOM) model of access to health services includes personal, financial, and structural barriers, health service utilization, and mediators of care. This model can be used to describe the interactions among these factors and their impact on health outcomes and equity of services among racial and ethnic groups. We present a modified version of the IOM model that incorporates the features of other access models and highlights barriers and mediators that are relevant for interventions designed to eliminate disparities in U.S. health care. We also suggest that interventions to eliminate disparities and achieve equity in health care services be considered within the broader context of improving quality of care. Some health service intervention studies have shown improvements in the health of disadvantaged groups. If properly designed and implemented, these interventions could be used to reduce health disparities. Successful features of interventions include the use of multifaceted, intense approaches, culturally and linguistically appropriate methods, improved access to care, tailoring, the establishment of partnerships with stakeholders, and community involvement. However, in order to be effective in reducing disparities in health care and health status, important limitations of previous studies need to be addressed, including the lack of control groups, nonrandom assignment of subjects to experimental interventions, and use of health outcome measures that are not validated. Interventions might be improved by targeting high-risk populations, focusing on the most important contributing factors, including measures of appropriateness and quality of care and health outcomes, and prioritizing dissemination efforts.

Health literacy and preventive health care use among Medicare enrollees in a managed care organization

BACKGROUND

Many older adults in Medicare managed care programs have low health literacy, and this may affect use of preventive services.

OBJECTIVES

To determine whether older adults with inadequate health literacy were less likely to report receiving influenza and pneumococcal vaccinations, mammograms, and Papanicolaou smears than individuals with adequate health literacy after adjusting for other covariates.

RESEARCH DESIGN

Cross-sectional survey; home interviews with community dwelling enrollees.

SUBJECTS

Medicare managed care enrollees 65 to 79 years old in four US cities (n = 2722).

MEASURES

Short Test of Functional Health Literacy in Adults and self-reported preventive service use.

RESULTS

In bivariate analyses, self-reported lack of preventive services was higher among individuals with inadequate health literacy than those with adequate health literacy: never had an influenza vaccination: 29% versus 19% (P = 0.000); never had a pneumococcal vaccination: 65% versus 54% (P = 0.000); no mammogram in the last 2 years: 24% versus 17% (P = 0.017); never had a Papanicolaou smear: 10% versus 5% (P = 0.002). After adjusting for demographics, years of school completed, income, number of physician visits, and health status, people with inadequate health literacy were more likely to report they had never received the influenza (OR, 1.4; 95% CI, 1.1-1.9) or pneumococcal vaccination (OR, 1.3; 95% CI, 1.1-1.7), and women were less likely to have received a mammogram (OR, 1.5; 95% CI, 1.0-2.2) or Papanicolaou smear (OR, 1.7; 95% CI, 1.0-3.1).

CONCLUSIONS

Among Medicare managed care enrollees, inadequate health literacy is independently associated with lower use of preventive health services.

Understanding the treatment preferences of seriously ill patients

BACKGROUND

The questions patients are asked about their preferences with regard to life-sustaining treatment usually focus on specific interventions, but the outcomes of treatment and their likelihood affect patients' preferences.

METHODS

We administered a questionnaire about treatment preferences to 226 persons who were 60 years of age or older and who had a limited life expectancy due to cancer, congestive heart failure, or chronic obstructive pulmonary disease. The study participants were asked whether they would want to receive a given treatment, first when the outcome was known with certainty and then with different likelihoods of an adverse outcome. The outcome without treatment was specified as death from the underlying disease.

RESULTS

The burden of treatment (i.e., the length of the hospital stay, extent of testing, and invasiveness of interventions), the outcome, and the likelihood of the outcome all influenced treatment preferences. For a low-burden treatment with the restoration of current health, 98.7 percent of participants said they would choose to receive the treatment (rather than not receive it and die), but 11.2 percent of these participants would not choose the treatment if it had a high burden. If the outcome was survival but with severe functional impairment or cognitive impairment, 74.4 percent and 88.8 percent of these participants, respectively, would not choose treatment. The number of participants who said they would choose treatment declined as the likelihood of an adverse outcome increased, with fewer participants choosing treatment when the possible outcome was functional or cognitive impairment than when it was death. Preferences did not differ according to the primary diagnosis.

CONCLUSIONS

Advance care planning should take into account patients' attitudes toward the burden of treatment, the possible outcomes, and their likelihood. The likelihood of adverse functional and cognitive outcomes of treatment requires explicit consideration.

Health literacy: a review

Illiteracy has become an increasingly important problem, especially as it relates to health care. A national survey found that almost half of the adult population has deficiencies in reading or computation skills. Literacy is defined as the basic ability to read and speak English, whereas functional health literacy is the ability to read, understand, and act on health information. Up to 48% of English-speaking patients do not have adequate functional health literacy. The consequences of inadequate health literacy include poorer health status, lack of knowledge about medical care and medical conditions, decreased comprehension of medical information, lack of understanding and use of preventive services, poorer self-reported health, poorer compliance rates, increased hospitalizations, and increased health care costs. The medical community must acknowledge this issue and develop strategies to ensure that patients receive assistance in overcoming the barriers that limit their ability to function adequately in the health care environment.

Comprehension of written health care information in an affluent geriatric retirement community: use of the Test of Functional Health Literacy

BACKGROUND

The comprehension of written health care information, e.g. prescription bottle labels or an informed consent form, impacts on communication with patients and their ability to understand medical procedures, as well as goals of therapy.

OBJECTIVE

To determine if the problem of literacy was present in a population of affluent Albuquerque retirement community dwellers.

METHODS

We administered the Test of Functional Health Literacy in Adults (TOFHL) to 93 residents (71 women and 22 men), using a one-on-one directed examination conducted by one of the authors (J.G.B.).

RESULTS

The group studied had a mean age of >70 years, were not acutely ill, had no known loss of mental function, were better educated and had a high standard of living compared to national standards. However, 30% (95% confidence level) of our group were unable to adequately comprehend written information as measured by the TOFHL. The subgroup with poor comprehension (21 women and 7 men) had a mean age of 85 years (versus 82 years in the group with good comprehension) and a mean of 13 years (versus 15 years in the group with good comprehension) of formal education. Multivariate analysis was consistent with a negative effect of age (p = 0.04), a positive effect of years of formal education (p = 0.0005) and no effect of gender on the TOFHL score.

CONCLUSION

Two recent studies, one in an emergency room setting and the other among Medicare enrollees, demonstrated similar results to ours. The high prevalence of poor comprehension in these groups should alert providers to the need to develop additional or different communication skills that can address the problem of poor reading comprehension across at least three diverse groups of people, with particular attention to those over the age of 65.

Physician-patient communication: a lost art?

In the face of rapid advances in technology, there has been a progressive deterioration of effective physician-patient communication. The American Academy of Orthopaedic Surgeons has identified that patients rate the orthopaedic profession as high in technical and low in communication skills. Poor communication, especially patient-interviewing skills, has been identified in medical students as well as in practicing physicians. Effective communication is associated with improved patient and physician satisfaction, better patient compliance, improved health outcomes, better-informed medical decisions, and reduced malpractice suits, and it likely contributes to reduced costs of care. Recognition of the importance of communication has influenced medical schools to revise curricula and to teach communication skills in residency training and continuing medical education programs. National certifying examinations also are being designed to incorporate these skills. Although written material is useful in increasing awareness of the importance of good physician-patient communication, behavioral change is more likely to occur in a workshop environment. The American Academy of Orthopaedic Surgeons is taking leadership in designing and implementing such an approach for its membership.

Health literacy and performance on the Mini-Mental State Examination

The objectives of the study were to determine the relationship between functional health literacy and performance on the Mini-Mental State Examination (MMSE). New Medicare managed-care enrollees aged 65 years and older, living independently in the community in four US cities (Cleveland, Houston, Tampa, and Fort Lauderdale/Miami), were eligible to participate. In-home interviews were conducted to determine demographics and health status, and interviewers then administered the Short Test of Functional Health Literacy in Adults (S-TOFHLA) and the MMSE. We then determined the relationship between functional health literacy and the MMSE, including total scores, subscale scores (orientation to time, orientation to place, registration, attention and calculation, recall, language, and visual construction), and individual items. Functional health literacy was linearly related to the total MMSE score across the entire range of S-TOFHLA scores (R(2) = 0.39, p < 0.001). This relationship between health literacy and MMSE was consistent across all MMSE subscales and individual items. Adjustment for chronic conditions and self-reported overall health did not change the relationship between health literacy and MMSE score. Health literacy was related to MMSE performance even for subscales of the MMSE that were not postulated to be directly dependent on reading ability or education (e.g. delayed recall). These results suggest that the lower MMSE scores for patients with low health literacy are only partly due to 'test bias' and also result from true differences in cognitive functioning. 'Adjusting' MMSE scores for an individual's functional health literacy may be inappropriate because it may mask true differences in cognitive functioning.
