Relation between literacy, race, and stage of presentation among low-income patients with prostate cancer

Systematic review of health literacy in Cochrane database studies on paediatric asthma educational interventions: searching beyond rigorous design

AIM

The purpose of this study was to evaluate if paediatric asthma educational intervention studies included in the Cochrane Collaboration database incorporated concepts of health literacy.

METHODS

Inclusion criteria were established to identify review categories in the Cochrane Collaboration database specific to paediatric asthma educational interventions. Articles that met the inclusion criteria were selected from the Cochrane Collaboration database in 2010. The health literacy definition from Healthy People 2010 was used to develop a 4-point a priori rating scale to determine the extent a study reported aspects of health literacy in the development of an educational intervention for parents and/or children.

RESULTS

Five Cochrane review categories met the inclusion criteria; 75 studies were rated for health literacy content regarding educational interventions with families and children living with asthma. A priori criteria were used for the rating process. While 52 (69%) studies had no information pertaining to health literacy, 23 (31%) reported an aspect of health literacy. Although all studies maintained the rigorous standards of randomized clinical trials, a model of health literacy was not reported regarding the design and implementation of interventions.

CONCLUSIONS

While a more comprehensive health literacy model for the development of educational interventions with families and children may have been available after the reviewed studies were conducted, general literacy levels still could have been addressed. The findings indicate a need to incorporate health literacy in the design of client-centred educational interventions and in the selection criteria of relevant Cochrane reviews. Inclusion assures that health literacy is as important as randomization and statistical analyses in the research design of educational interventions and may even assure participation of people with literacy challenges.

Understanding the psychosocial issues of African American couples surviving prostate cancer

African Americans are disproportionately affected by prostate cancer, yet less is known about the most salient psychosocial dimensions of quality of life. The purpose of this study was to explore the perceptions of African American prostate cancer survivors and their spouses of psychosocial issues related to quality of life. Twelve African American couples were recruited from a National Cancer Institute Comprehensive Cancer Center registry and a state-based non-profit organization to participate in individual interviews. The study was theoretically based on Ferrell's Quality of Life Conceptual Model. Common themes emerged regarding the psychosocial needs of African American couples. These themes were categorized into behavioral, social, psychological, and spiritual domains. Divergent perspectives were identified between male prostate cancer survivors and their female spouses. This study delineated unmet needs and areas for future in-depth investigations into psychosocial issues. The differing perspectives between patients and their spouses highlight the need for couple-centered interventions.

Self-reported use of communication techniques in the emergency department

BACKGROUND

Communication is considered a core competency for physicians. However, the Emergency Department setting poses significant and unique communication challenges.

OBJECTIVE

The objective of this study was to explore self-reported use and perceptions of effectiveness and feasibility of communication techniques used by Emergency Physicians for communication with patients.

METHODS

This cross-sectional study utilized a previously published survey on eight communication techniques. Respondents were asked to quantify their personal use and perceptions of effectiveness and feasibility of each technique. Responses were analyzed for differences based on practice setting (community, academic) and provider role (attending, resident). The survey was administered to a convenience sample recruited at the national meeting of the American College of Emergency Physicians.

RESULTS

One hundred and sixty-nine participants were enrolled (70.5% male; 55.8% attending physicians, 44.2% residents; 66.2% practiced in academic settings). Using simple language and speaking slowly to patients were the only techniques identified as being used routinely by a majority of the sample (92.2% and 61.3%, respectively). A majority of the sample ranked seven of the techniques as effective; all techniques were considered feasible in the Emergency Department. No differences were noted across provider role or practice setting.

CONCLUSION

The majority of respondents are not utilizing communication techniques, despite their own beliefs that the techniques are effective and easy to implement in the Emergency Department. Additional research is needed to determine the effectiveness of these techniques and relevant barriers to their use.

Prostate cancer mortality and birth or adult residence in the southern United States

PURPOSE

Although there are few confirmed risk factors for prostate cancer (PCa), mortality rates are known to vary geographically across the United States. PCa mortality is higher among black and younger white men in a band of states spanning from Washington DC to Louisiana (the "PCa belt"). This study assessed the associations of birth and adult residence in the PCa belt with PCa mortality among black and white men and trends in these associations over time.

METHODS

PCa-specific mortality rates in 1980, 1990, and 2000 for black and white men born in the continental US, aged 40-89, were calculated by linking national mortality records with population data based on birth state, state of residence at the census, race, and age. PCa belt (Washington DC, Virginia, North Carolina, South Carolina, Georgia, Mississippi, Alabama, and Louisiana) birth was cross-classified against PCa belt adult residence.

RESULTS

Black men born in the PCa belt had elevated PCa mortality in 1980, 1990, and 2000. Associations were independent of adult residence in the PCa belt. For example, in 2000, black men aged 65-89 who were born in the PCa belt but no longer lived there in adulthood had an odds ratio of 1.19 (1.14-1.24) for PCa mortality compared to black men born and residing outside the PCa belt. The PCa belt was not associated with PCa mortality among whites.

CONCLUSIONS

Geographically patterned childhood exposures, for example, differences in social or environmental conditions, or behavioral norms, may influence PCa mortality.

Prostate cancer epidemiology in the United States

BACKGROUND

Prostate cancer is a significant public health issue in the United States. It is the most commonly diagnosed non-skin cancer and the second leading cause of cancer death. The American Cancer Society estimates that in 2011, 240,890 men were diagnosed with prostate cancer and 33,720 men died of it.

METHODS

A review of the peer-reviewed literature was conducted: American Cancer Society, National Cancer Institute Surveillance, Epidemiology and End Results. Program data were assessed to describe trends in incidence, mortality, and survival rates and look at other predictors of risk of prostate cancer diagnosis and death.

RESULTS

Since 1985, there have been significant changing trends in prostate cancer incidence, mortality, and survival rates, as well as changes in the age distribution of the population diagnosed and even in the distribution of pathologies at diagnosis. Major risk factors for diagnosis include age, family history, race, and screening behavior.

CONCLUSION

While prostate cancer remains largely a disease diagnosed in older men (over age 65), screening has increased risk of diagnosis among men in their 40s and 50s. The incidence rates and 5-year survival rates are heavily influenced by the introduction of serum prostate-specific antigen (PSA) and widespread screening. The effects of PSA usage and screening on mortality rates are less certain. Outcome studies among men treated with radical prostatectomy show that greater than 30% relapse rates are common. This suggests that many men who are diagnosed with "localized early stage disease" actually have "apparently localized early stage disease," which is really low volume metastatic disease.

The impact of health literacy and socioeconomic status on asthma disparities

OBJECTIVE

Racial/ethnic disparities have been well documented in asthma. While socioeconomic status (SES) has been repeatedly implicated as a root cause, the role of limited health literacy has not been extensively studied. The purpose of this study was to examine the independent contributions of SES and health literacy in explaining asthma disparities.

METHODS

A cohort study was conducted in a Chicago-based sample of 353 adults aged 18-40 years with persistent asthma from 2004 to 2007. Health literacy, SES, and asthma outcomes including disease control, quality of life, emergency department visits, and hospitalizations were assessed in person at baseline, and asthma outcomes were measured every 3 months for 2 years by phone. Multivariate models were used to assess racial/ethnic disparities in asthma outcomes and the effect of health literacy and SES on these estimates.

RESULTS

Compared with White participants, African American adults fared significantly worse in all asthma outcomes (p < .05) and Latino participants had lower quality of life (β = -0.47; 95% confidence interval [CI] = -0.79, -0.14; p = .01) and worse asthma control (risk ratio [RR] = 0.63; 95% CI = 0.41, 0.98; p = .04). Differences in SES partially explained these disparities. Health literacy explained an additional 20.2% of differences in quality of life between Latinos and Whites, but differences in hospitalization rates between African American and White adults remained (RR = 2.97; 95% CI = 1.09, 8.12, p = .03).

CONCLUSIONS

Health literacy appears to be an overlooked factor explaining racial and ethnic disparities in asthma. Evidence-based low literacy strategies for patient education and counseling should be included in comprehensive interventions.

Measurement variation across health literacy assessments: implications for assessment selection in research and practice

National priorities and recent federal initiatives have brought health literacy to the forefront in providing safe accessible care. Having valid and reliable health literacy measures is a critical factor in meeting patients' health literacy needs. In this study, the authors examined variation across three brief health literacy instruments in categorizing health literacy levels and identifying associated factors. The authors screened 378 veterans using the short form of the Test of Functional Health Literacy in Adults; the Rapid Estimate of Adult Literacy in Medicine; and a 4-Item Brief Health Literacy Screening Tool (known as the BRIEF). They analyzed data using prevalence estimates, Pearson product moment correlations, and logistic regression. When categorizing individuals' health literacy, agreement among instruments was present for 37% of the sample. There were consistencies; however, categorization and estimated risk factors varied by instrument. Depending on instrument, increased age, low education, minority status, and self-reported poor reading level were associated with low health literacy. Findings suggest that these instruments measure health literacy differently and are likely conceptually different. As the use of health literacy screening gains momentum, alignment between instrument and intended purpose is essential; in some cases, multiple instruments may be appropriate. When selecting an instrument, one should consider style of administration, purpose for measure, and availability of time and resources.

How does health literacy affect quality of life among men with newly diagnosed clinically localized prostate cancer? Findings from the North Carolina-Louisiana Prostate Cancer Project (PCaP)

BACKGROUND

Health literacy deficits affect half of the US overall patient population, especially the elderly, and are linked to poor health outcomes among noncancer patients. Yet little is known about how health literacy affects cancer populations. The authors examined the relation between health-related quality of life (HRQOL) and health literacy among men with prostate cancer.

METHODS

Data analysis included 1581 men with newly diagnosed clinically localized prostate cancer from a population-based study, the North Carolina-Louisiana Prostate Cancer Project (PCaP). Participants completed assessment of health literacy using Rapid Estimate of Adult Literacy in Medicine (REALM) and HRQOL using the Short Form-12 General Health Survey (SF12). Bivariate and multivariate regression was used to determine the potential association between REALM and HRQOL, while controlling for sociodemographic and illness-related variables.

RESULTS

Higher health literacy level was significantly associated with better mental well-being (SF12-Mental Component Summary [MCS]; P < .001) and physical well-being (SF12-Physical Component Summary [PCS]; P < .001) in bivariate analyses. After controlling for sociodemographic (age, marital status, race, income, and education) and illness-related factors (types of cancer treatment, tumor aggressiveness, and comorbidities), health literacy remained significantly associated with SF12-MCS scores (P < .05) but not with SF12-PCS scores.

CONCLUSIONS

Among patients with newly diagnosed localized prostate cancer, those with low health literacy levels were more vulnerable to mental distress than those with higher health literacy levels, but physical well-being was no different. These findings suggest that health literacy may be important in patients managing prostate cancer and the effects of treatment, and provide the hypothesis that supportive interventions targeting patients with lower health literacy may improve their HRQOL.

How does health information influence African American men's health behavior?

Few researchers have examined where African American men obtain, process, and use health information. A thematic analysis of data from eighteen exploratory focus groups conducted with 154 urban African American men aged 32 years and older revealed that men received health information from a variety of sources, including health professionals, media, and members of their social networks. At times, information raised their awareness of health issues, but trust in the source of the information influenced how this information was perceived. Medical professionals were the most common source of health information, but family members were the most trusted source of health information. Health problems and social support increased men's motivation to use health information in order to improve their health and healthy behaviors. These findings illustrate that it is critical to identify factors that influence what information men choose to believe and follow or decide to ignore.

Psychosocial factors associated with mouth and throat cancer examinations in rural Florida

OBJECTIVES

We examined the knowledge and prevalence of mouth and throat cancer examinations in a sample drawn from rural populations in north Florida.

METHODS

Telephone interviews were conducted across rural census tracts throughout north Florida in 2009 and 2010, in a survey that had been adapted for cultural appropriateness using cognitive interviews. The sample consisted of 2526 respondents (1132 men and 1394 women; 1797 Whites and 729 African Americans).

RESULTS

Awareness of mouth and throat cancer examination (46%) and lifetime receipt (46%) were higher than reported in statewide studies performed over the past 15 years. Only 19% of the respondents were aware of their examination, whereas an additional 27% reported having the examination when a description was provided, suggesting a lack of communication between many caregivers and rural patients. Surprisingly, anticipated racial/ethnic differences were diminished when adjustments were made for health literacy and several measures of socioeconomic status.

CONCLUSIONS

These findings support the notion that health disparities are multifactorial and include characteristics such as low health literacy, lack of access to care, and poor communication between patient and provider.

Health literacy and decision making styles for complex antithrombotic therapy among older multimorbid adults

OBJECTIVES

To evaluate the effect of functional health literacy (FHL) on preferences for decision-making; and among those initially preferring a passive decision-making role, to explore how preferences change if their physician actively encourages their involvement.

METHODS

Consecutive older adults with cardiovascular disease receiving complex antithrombotic therapy completed a comprehensive assessment including measures of FHL and preferences for shared decision making.

RESULTS

Half of all participants had inadequate or marginal FHL. Those with inadequate FHL were more likely (P=0.01) to prefer passive rather than active decision making styles even after controlling for age, education, and numeracy. However, 40% of patients preferring passive styles had adequate FHL and these patients were significantly more likely to change their preference to more active styles (odds ratio=7.17, P<.01) if their physician "was more supportive or encouraged participation".

CONCLUSIONS

Screening FHL can provide insight into patients' preferences for active participation in decision making. Clinicians' encouragement of participation can increase engagement by patients with adequate FHL.

PRACTICE IMPLICATIONS

We propose an algorithm for screening FHL and preferences for participating in decisions about complex medication regimens.

What should laypersons know about cancer? Towards an operational definition of cancer literacy

OBJECTIVE

To operationally define cancer literacy, understanding which aspects of cancer are important to be known by a layperson to be considered cancer literate.

METHODS

A Delphi study in three consecutive rounds was conducted among a panel of Swiss cancer experts (oncologists, GPs, nurses from oncology wards, social workers, public health experts).

RESULTS

The result of the Delphi process is a first operational definition of the concept of cancer literacy, a list of the aspects of cancer that, in the expert's view, laypeople should know to be considered cancer literate.

CONCLUSIONS

We have now an idea of what should be known about cancer. The study also provides us with some useful hints about what should be communicated about cancer, e.g. via public communication campaigns, school education, or media.

PRACTICE IMPLICATIONS

The operational definition of the concept can be used for the development and the validation of a measure of cancer literacy, not anymore limited to basic literacy and numeracy skills.

Black men have lower rates than white men of biochemical failure with primary androgen-deprivation therapy

INTRODUCTION

Black men have a higher incidence of advanced stage at diagnosis and mortality from prostate cancer than do men in other racial groups. Given that androgen-deprivation therapy (ADT) is one of the mainstays of treatment for advanced prostate cancer, we investigated the development of biochemical failure, or recurrence of elevated prostate-specific antigen (PSA) levels, among different races in men receiving ADT.

METHODS

Patients with prostate cancer who received ADT in the Kaiser Permanente Southern California Cancer Registry between January 2003 and December 2006 were eligible for inclusion in our study. Patients who had prior treatment for their cancer with surgery or radiation were excluded. Treatment failure was defined as an increase in PSA of >2 ng/mL from PSA nadir, with no subsequent decrease in PSA. We compared the biochemical failure rate in white patients to those in black, Hispanic, and Asian/other patients. The Cox proportional hazards regression model was used to estimate hazards ratios.

RESULTS

Our study population consisted of 681 patients: 416 (61%) were white; 107 (16%) were black; 107 (16%) were Hispanic; and 51 (7%) were Asian or another race. After we controlled for all demographic variables and for variables related to prostate cancer, blacks were the only group with a lower risk of treatment failure compared with whites. The hazard ratios for treatment failure were as follows: black versus white, 0.66 (p = 0.03); Hispanic versus white, 1.00 (p = 0.8); Asian/other race versus white, 1.5 (p = 0.1). In this multivariate analysis, pretreatment PSA level and cancer stage were the only other variables associated with a higher risk of treatment failure.

CONCLUSION

Among patients receiving ADT as primary monotherapy for prostate cancer, blacks may have a lower rate of biochemical failure compared with whites. Although the etiology of this finding is unclear, it suggests the possibility that prostate cancer in black men may be more androgen sensitive than it is in white men.

Health literacy, numeracy, and interpretation of graphical breast cancer risk estimates

OBJECTIVE

Health literacy and numeracy are necessary to understand health information and to make informed medical decisions. This study explored the relationships among health literacy, numeracy, and ability to accurately interpret graphical representations of breast cancer risk.

METHODS

Participants (N=120) were recruited from the Facing Our Risk of Cancer Empowered (FORCE) membership. Health literacy and numeracy were assessed. Participants interpreted graphs depicting breast cancer risk, made hypothetical treatment decisions, and rated preference of graphs.

RESULTS

Most participants were Caucasian (98%) and had completed at least one year of college (93%). Fifty-two percent had breast cancer, 86% had a family history of breast cancer, and 57% had a deleterious BRCA gene mutation. Mean health literacy score was 65/66; mean numeracy score was 4/6; and mean graphicacy score was 9/12. Education and numeracy were significantly associated with accurate graph interpretation (r=0.42, p<0.001 and r=0.65, p<0.001, respectively). However, after adjusting for numeracy in multivariate linear regression, education added little to the prediction of graphicacy (r(2)=0.41 versus 0.42, respectively).

CONCLUSION

In our highly health-literate population, numeracy was predictive of graphicacy.

PRACTICE IMPLICATIONS

Effective risk communication strategies should consider the impact of numeracy on graphicacy and patient understanding.

Oral health literacy levels among a low-income WIC population

OBJECTIVES

To determine oral health literacy (OHL) levels and explore potential racial differences in a low-income population.

METHODS

This was a cross-sectional study of caregiver/child dyads that completed a structured 30-minute in-person interview conducted by two trained interviewers in seven counties in North Carolina. Sociodemographic, OHL, and dental health-related data were collected. OHL was measured with a dental word recognition test [Rapid Estimate of Adult Literacy in Dentistry (REALD-30)]. Descriptive, bivariate, and multivariate methods were used to examine the distribution of OHL and explore racial differences.

RESULTS

Of 1658 eligible subjects, 1405 (85 percent) participated and completed the interviews. The analytic sample (N=1280) had mean age 26.5 (standard deviation = 6.9) years with 60 percent having a high school degree or less. OHL varied between racial groups as follows: Whites--mean score = 17.4 (SE = 0.2); African-American (AA)--mean score = 15.3 [standard error (SE) = 0.2]; American Indian (AI)--mean score = 13.7 (SE = 0.3). Multiple linear regression revealed that after controlling for education, county of residence, age, and Hispanic ethnicity, Whites had 2.0 points (95 percent CI = 1.4, 2.6) higher adjusted REALD-30 score versus AA and AI.

CONCLUSIONS

Differences in OHL levels between racial groups persisted after adjusting for education and sociodemographic characteristics.

Age differences in genetic knowledge, health literacy and causal beliefs for health conditions

OBJECTIVES

This study examined the levels of genetic knowledge, health literacy and beliefs about causation of health conditions among individuals in different age groups.

METHODS

Individuals (n = 971) recruited through 8 community health centers in Suffolk County, New York, completed a one-time survey.

RESULTS

Levels of genetic knowledge were lower among individuals in older age groups (26-35, p = 0.011; 36-49, p = 0.002; 50 years and older, p<0.001) compared to those in the youngest age group (18-25). Participants in the oldest age group also had lower health literacy than those in the youngest group (p <0.001). Those in the oldest group were more likely to endorse genetic (OR = 1.87, p = 0.008) and less likely to endorse behavioral factors like diet, exercise and smoking (OR = 0.55, p = 0.010) as causes of a person's body weight than those in the youngest group. Higher levels of genetic knowledge were associated with higher likelihood of behavioral attribution for body weight (OR = 1.25, p <0.001).

CONCLUSIONS

Providing additional information that compensates for their lower genetic knowledge may help individuals in older age groups benefit from rapidly emerging genetic health information more fully. Increasing the levels of genetic knowledge about common complex diseases may help motivate individuals to engage in health promoting behaviors to maintain healthy weight through increases in behavioral causal attributions.

Patient attitudes and preferences regarding literacy screening in ambulatory cancer care clinics

OBJECTIVES

To evaluate patient attitudes towards literacy screening, agreement between literacy tests, and associations between literacy, informed consent comprehension, and health-related quality of life (HRQL).

METHODS

Participants completed three literacy tests, read a sample consent form, and reported their HRQL, experiences, and attitudes.

RESULTS

We enrolled 97 cancer patients, of whom 66% were female, 67% were African American, and 65% were high school graduates. Sixty percent of patients with lower reading comprehension had trouble reading health information, and 31% had trouble reading everyday written material. Even patients with higher reading comprehension had trouble reading health information (29%) and everyday written material (10%). Low-literacy patients were more likely to feel anxious about literacy screening. However, the majority of patients (84%) would be willing to have literacy results given to providers. Comprehension of informed consent increased with higher literacy. There were no HRQL differences.

CONCLUSIONS

Patients report difficulty comprehending written health information. Literacy assessment is acceptable and it is considered important for providers to be aware of their patients' reading abilities. Patient preference data should be used to improve literacy testing strategies and measures. Enhancing detection of low literacy can facilitate interventions to reduce health disparities.

Applicability of a video intervention to increase informed decision making for prostate-specific antigen testing

PURPOSE

To evaluate the applicability of an evidence-based video intervention to promote informed decision making for prostate cancer screening among African American men with different levels of health literacy.

METHODS

Forty nine African American men participated in interviewer-administered, pretest and posttest interviews between January and March 2008. Health literacy status was assessed with the Test of Functional Health Literacy in Adults. Repeated measures analysis of covariance (ANCOVA), McNemar or binomial distributions were computed to assess pretest and posttest differences in knowledge. Descriptive statistics were produced to describe participants' perceptions of the information presented in the video.

RESULTS

Results indicated that men with functional health literacy had higher mean levels of prostate cancer screening knowledge at baseline than men with inadequate health literacy. The between-group (F2,44= 4.84; p = .013) and within-group (F1,44 = 5.16; p = .028) test results from repeated-measures ANCOVA indicated that preexisting group differences in prostate cancer knowledge had lessened after intervention exposure. Nearly all men rated the information presented in the video as credible (98%), trustworthy (96%), interesting (100%), understandable (94%), and complete (96%).

CONCLUSIONS

Results from this exploratory study suggest that the video intervention is suitable for use with African American men with different health literacy characteristics in 2 counties in the greater Florida panhandle region. More research is recommended to evaluate the impact of the intervention on men's intentions to undergo screening and actual screening behavior.

Health literacy and health seeking behavior among older men in a middle-income nation

Health literacy is a measure of the patient’s ability to read, comprehend and act on medical instructions. This research article examines health literacy and health-seeking behaviors among elderly men in Jamaica, in order to inform health policy. This is a descriptive cross-sectional study. A 133-item questionnaire was administered to a random sample of 2,000 men, 55 years and older, in St Catherine, Jamaica. In this study, 56.9% of urban and 44.5% of rural residents were health literate. Only 34.0% of participants purchased medications prescribed by the medical doctor and 19.8% were currently smoking. Despite the reported good self-related health status (74.4%) and high cognitive functionality (94.1%) of the older men, only 7.9% sought medical care outside of experiencing illnesses. Thirty-seven percent of rural participants sought medical care when they were ill compared with 31.9% of their urban counterparts. Thirty-four percent of the participants took the medication as prescribed by the medical doctor; 43% self-reported being diagnosed with cancers such as prostate and colorectal in the last 6 months, 9.6% with hypertension, 5.3% with heart disease, 5.3% with benign prostatic hyperplasia, 5.3% with diabetes mellitus, and 3.8% with kidney/bladder problems. Approximately 14% and 24% of the participants indicated that they were unaware of the signs and symptoms of hypertension and diabetes mellitus, respectively. The elderly men displayed low health literacy and poor health-seeking behavior. These findings can be used to guide the formulation of health policies and intervention programs for elderly men in Jamaica.

Barriers to treatment seeking for anxiety disorders: initial data on the role of mental health literacy

BACKGROUND

Anxiety disorders represent the single largest mental health problem in the United States [Greenberg et al., 1999. J Clin Psychiatry 60:427-435; Rice and Miller, 1998. Br J Psychiatry 173:4-9]. However most individuals with anxiety disorders never seek treatment [Henderson et al., 2002. Can J Psychiatry 47:819-824; Mojtabai et al., 2002. Arch Gen Psychiatry 59:77-84; Roness et al., 2005. Acta Psychiatr Scand 111:51-58]. Deficits in the ability to recognize anxiety disorders and beliefs about them, (i.e., "mental health literacy") may contribute to low levels of help seeking.

METHODS

Survey data assessing mental health literacy for multiple anxiety disorders and for depression were collected from 284 undergraduate students enrolled in psychology courses at a public university in the United States. Specifically, respondents were presented with vignettes portraying individuals experiencing various forms of mental illness and were asked to label the disorder, its cause and whether or not they would recommend treatment.

RESULTS

Findings showed that social phobia and obsessive compulsive disorder (OCD) were associated with recognition rates that were generally high and similar to depression (approximately 80%). In contrast, less than half of the respondents labeled panic disorder or generalized anxiety disorder (GAD) correctly. Symptoms of OCD were attributed to mental illness by approximately 50% of respondents, but such attributions were rare for the other anxiety disorders studied (<12%). Finally, data on help-seeking recommendations suggested that such recommendations are far from universal and varied between different anxiety disorders and according to perceptions of the causes of symptoms.

CONCLUSIONS

Given that the current sample was well-educated young adults, mental health literacy of the general public may be even lower.

Associations between indigenous Australian oral health literacy and self-reported oral health outcomes

OBJECTIVES

To determine oral health literacy (REALD-30) and oral health literacy-related outcome associations, and to calculate if oral health literacy-related outcomes are risk indicators for poor self-reported oral health among rural-dwelling Indigenous Australians.

METHODS

468 participants (aged 17-72 years, 63% female) completed a self-report questionnaire. REALD-30 and oral health literacy-related outcome associations were determined through bivariate analysis. Multivariate modelling was used to calculate risk indicators for poor self-reported oral health.

RESULTS

REALD-30 scores were lower among those who believed teeth should be infrequently brushed, believed cordial was good for teeth, did not own a toothbrush or owned a toothbrush but brushed irregularly. Tooth removal risk indicators included being older, problem-based dental attendance and believing cordial was good for teeth. Poor self-rated oral health risk indicators included being older, healthcare card ownership, difficulty paying dental bills, problem-based dental attendance, believing teeth should be brushed infrequently and irregular brushing. Perceived need for dental care risk indicators included being female and problem-based dental attendance. Perceived gum disease risk indicators included being older and irregular brushing. Feeling uncomfortable about oro-facial appearance risk indicators included problem-based dental attendance and irregular brushing. Food avoidance risk indicators were being female, difficulty paying dental bills, problem-based dental attendance and irregular brushing. Poor oral health-related quality of life risk indicators included difficulty paying dental bills and problem-based dental attendance.

CONCLUSIONS

REALD-30 was significantly associated with oral health literacy-related outcomes. Oral health literacy-related outcomes were risk indicators for each of the poor self-reported oral health domains among this marginalised population.

Healthcare access, socioeconomic factors and late-stage cancer diagnosis: an exploratory spatial analysis and public policy implication

Patients diagnosed with late-stage cancer have lower survival rates than those with early-stage cancer. This paper examines possible associations between several risk factors and late-stage diagnosis for four types of cancer in Illinois: breast cancer, prostate cancer, colorectal cancer, and lung cancer. Potential risk factors are composed of spatial factors and nonspatial factors. The spatial factors include accessibility to primary healthcare and distance or travel time to the nearest cancer screening facility. A set of demographic and socioeconomic variables are consolidated into three nonspatial factors by factor analysis. The Bayesian model with convolution priors is utilised to analyse the relationship between the above risk factors and each type of late-stage cancer while controlling for spatial autocorrelation. The results for breast cancer suggest that people living in neighbourhoods with socioeconomic disadvantages and cultural barriers are more likely to be diagnosed at a late stage. In regard to prostate cancer, people in regions with low socioeconomic status are also more likely to be diagnosed at a late stage. Diagnosis of late-stage colorectal or lung cancer is not significantly associated with any of the abovementioned risk factors. The results have important implications in public policy.

Health literacy and child health promotion: implications for research, clinical care, and public policy

The nation's leading sources of morbidity and health disparities (eg, preterm birth, obesity, chronic lung disease, cardiovascular disease, type 2 diabetes, mental health disorders, and cancer) require an evidence-based approach to the delivery of effective preventive care across the life course (eg, prenatal care, primary preventive care, immunizations, physical activity, nutrition, smoking cessation, and early diagnostic screening). Health literacy may be a critical and modifiable factor for improving preventive care and reducing health disparities. Recent studies among adults have established an independent association between lower health literacy and poorer understanding of preventive care information and poor access to preventive care services. Children of parents with higher literacy skills are more likely to have better outcomes in child health promotion and disease prevention. Adult studies in disease prevention have suggested that addressing health literacy would be an efficacious strategy for reducing health disparities. Future initiatives to reduce child health inequities should include health-promotion strategies that meet the health literacy needs of children, adolescents, and their caregivers.

Racial differences in trust and regular source of patient care and the implications for prostate cancer screening use

BACKGROUND

: Nonmedical factors may modify the biological risk of prostate cancer (PCa) and contribute to the differential use of early detection; curative care; and, ultimately, greater racial disparities in PCa mortality. In this study, the authors examined patients' usual source of care, continuity of care, and mistrust of physicians and their association with racial differences in PCa screening.

METHODS

: Study nurses conducted in-home interviews of 1031 African-American men and Caucasian-American men aged > or =50 years in North Carolina and Louisiana within weeks of their PCa diagnosis. Medical records were abstracted, and the data were used to conduct bivariate and multivariate analyses.

RESULTS

: Compared with African Americans, Caucasian Americans exhibited higher physician trust scores and a greater likelihood of reporting a physician office as their usual source of care, seeing the same physician at regular medical encounters, and historically using any PCa screening. Seeing the same physician for regular care was associated with greater trust and screening use. Men who reported their usual source of care as a physician office, hospital clinic, or Veterans Administration facility were more likely to report prior PCa screening than other men. In multivariate regression analysis, seeing the same provider remained associated with prior screening use, whereas both race and trust lost their association with prior screening.

CONCLUSIONS

: The current results indicated that systems factors, including those that differ among different sources of care and those associated with the continuity of care, may provide tangible targets to address disparities in the use of PCa early detection, may attenuate racial differences in PCa screening use, and may contribute to reduced racial disparities in PCa mortality.

Literacy and learning in health care

The relationship between literacy and health outcomes are well documented in adult medicine, yet specific causal pathways are not entirely clear. Despite an incomplete understanding of the problem, numerous interventions have already been implemented with variable success. Many of those who proposed earlier strategies assumed the problem to originate from reading difficulties only. Given the timely need for more effective interventions, it is of increasing importance to reconsider the meaning of health literacy to advance our conceptual understanding of the problem and how best to respond. One potentially effective approach might involve recognizing the known associations between a larger set of cognitive and psychosocial abilities with functional literacy skills. Here we review the current health literacy definition and literature and draw on relevant research from the fields of education, cognitive science, and psychology. In this framework, a research agenda is proposed that considers an individual's "health-learning capacity," which refers to the broad constellation of cognitive and psychosocial skills from which patients or family members must draw to effectively promote, protect, and manage their own or a child's health. This new, related concept will lead, ideally, to more effective ways of thinking about health literacy interventions, including the design of health-education materials, instructional strategies, and the delivery of health care services to support patients and families across the life span.

Medical word use in clinical encounters

OBJECTIVE

Doctors often use medical language with their patients despite findings from a variety of studies that have shown that patients frequently misunderstand medical terminology. Little is known about the patterns of medical word use by doctors and patients during clinical encounters.

METHODS

A content analysis of 16 verbatim transcripts of first clinical encounters between rheumatologists and newly referred patients was conducted to assess how doctors and patients introduced medical words. Medical words were identified via a computer program using a defined list.

RESULTS

Doctors did not introduce or use more medical words than patients, but the types of words that doctors and patients introduced did differ. The majority of patient-initiated medical words occurred during the history taking (94%). Doctors did not explain, or use as part of an explanation, the majority (79%) of the medical words they introduced, and patients seldom responded in a way that would indicate whether or not they had correctly interpreted those terms. There was relatively little repetition of medical words within or even across encounters.

CONCLUSIONS

This study provides insights into how the use of medical terminology could contribute to misunderstanding. Findings suggest that steps already promoted in the literature to improve doctor-patient communication may also ameliorate potential problems arising from the use of medical terminology.

Health literacy skills of kidney transplant recipients

CONTEXT

Although low health literacy can affect patients' treatment decision making, comprehension of health information, and medication adherence, little is known about health literacy skills of kidney transplant recipients.

OBJECTIVE

To examine the relationship among kidney transplant recipients' health literacy levels, transplant knowledge, and graft function.

DESIGN

Cross-sectional study of 124 adult kidney transplant recipients.

MAIN OUTCOME MEASURES

Health literacy was assessed via the Short Test of Functional Health Literacy in Adults (S-TOFHLA) and the Rapid Estimate of Adult Literacy in Medicine-Transplantation (REALM-T). Data on recipients' transplant numeracy, knowledge needs, and demographics were collected via semistructured interviews. Multivariable linear regressions were used to assess the relationship between health literacy and graft function.

RESULTS

Most kidney recipients (91%) had adequate health literacy (S-TOFHLA); however, 81% were unfamiliar with at least 1 kidney transplant-related term (REALM-T). The 5 least familiar terms were sensitization (50%), urethra (45%), trough level (41%), blood urea nitrogen (32%), and toxicity (31%). Numeracy levels varied: 21% knew the likelihood of 1-year graft survival; 29% knew that half of kidney recipients have problems with the transplant in the first 6 months; 68% were aware of the risk of death within the first year after transplantation; and 86% knew the normal range for creatinine in kidney recipients. Patients with lower health literacy (REALM-T) had higher creatinine levels.

CONCLUSIONS

Transplant providers should intervene with better patient education materials to improve patients' health literacy, which may improve patients' medication adherence or transplant outcomes.

Health literacy and physical and psychological wellbeing in Japanese adults

OBJECTIVE

To determine the prevalence of low health literacy and investigate the relationship between low health literacy and physical and psychological wellbeing in the Japanese general population.

METHODS

A web-based cross-sectional survey was conducted in a national sample of Japanese adults. Health literacy was measured by self-report using the validated single-item screening question, "How confident are you filling out forms by yourself?" Wellbeing was measured with the physical and psychological domains of the World Health Organization Quality of Life Assessment-BREF. Effect sizes were computed by dividing the mean difference in scores by the standard deviation of the scores of all participants.

RESULTS

In 1040 adult enrollees (mean age, 57-year-old; women, 52%), there were 161 (15.5%; 95% confidence interval [CI], 13.3-17.7%) with low health literacy. Individuals with low health literacy reported lower physical wellbeing (60.6 vs. 71.7, p<0.001) and psychological wellbeing (59.7 vs. 68.3, p<0.001) compared with those with adequate health literacy. After adjusting for sociodemographic characteristics, health risk behaviors and chronic conditions, these differences were still significant (physical wellbeing, p<0.001; psychological wellbeing, p<0.001). The effect sizes of the difference of scores were moderate for physical wellbeing (-0.55) and also for psychological wellbeing (-0.44).

CONCLUSION

The prevalence of self-reported low health literacy in Japanese adults is substantial and it is independently associated with poorer physical and mental wellbeing.

PRACTICE IMPLICATIONS

Efforts to monitor health literacy and to evaluate causal pathways to poor wellbeing should be encouraged in the Japanese population.

Race and time from diagnosis to radical prostatectomy: does equal access mean equal timely access to the operating room?--Results from the SEARCH database

BACKGROUND

African American men with prostate cancer are at higher risk for cancer-specific death than Caucasian men. We determine whether significant delays in management contribute to this disparity. We hypothesize that in an equal-access health care system, time interval from diagnosis to treatment would not differ by race.

METHODS

We identified 1,532 African American and Caucasian men who underwent radical prostatectomy (RP) from 1988 to 2007 at one of four Veterans Affairs Medical Centers that comprise the Shared Equal-Access Regional Cancer Hospital (SEARCH) database with known biopsy date. We compared time from biopsy to RP between racial groups using linear regression adjusting for demographic and clinical variables. We analyzed risk of potential clinically relevant delays by determining odds of delays >90 and >180 days.

RESULTS

Median time interval from diagnosis to RP was 76 and 68 days for African Americans and Caucasian men, respectively (P = 0.004). After controlling for demographic and clinical variables, race was not associated with the time interval between diagnosis and RP (P = 0.09). Furthermore, race was not associated with increased risk of delays >90 (P = 0.45) or >180 days (P = 0.31).

CONCLUSIONS

In a cohort of men undergoing RP in an equal-access setting, there was no significant difference between racial groups with regard to time interval from diagnosis to RP. Thus, equal-access includes equal timely access to the operating room. Given our previous finding of poorer outcomes among African Americans, treatment delays do not seem to explain these observations. Our findings need to be confirmed in patients electing other treatment modalities and in other practice settings.

Health Literacy Skills of Kidney Transplant Recipients

Context

Although low health literacy can affect patients' treatment decision making, comprehension of health information, and medication adherence, little is known about health literacy skills of kidney transplant recipients.

Objective

To examine the relationship among kidney transplant recipients' health literacy levels, transplant knowledge, and graft function.

Design

Cross-sectional study of 124 adult kidney transplant recipients.

Main Outcome Measures

Health literacy was assessed via the Short Test of Functional Health Literacy in Adults (S-TOFHLA) and the Rapid Estimate of Adult Literacy in Medicine-Transplantation (REALM-T). Data on recipients' transplant numeracy, knowledge needs, and demographics were collected via semistructured interviews. Multivariable linear regressions were used to assess the relationship between health literacy and graft function.

Results

Most kidney recipients (91%) had adequate health literacy (S-TOFHLA); however, 81% were unfamiliar with at least 1 kidney transplant–related term (REALM-T). The 5 least familiar terms were sensitization (50%), urethra (45%), trough level (41%), blood urea nitrogen (32%), and toxicity (31%). Numeracy levels varied: 21% knew the likelihood of 1-year graft survival; 29% knew that half of kidney recipients have problems with the transplant in the first 6 months; 68% were aware of the risk of death within the first year after transplantation; and 86% knew the normal range for creatinine in kidney recipients. Patients with lower health literacy (REALM-T) had higher creatinine levels.

Conclusions

Transplant providers should intervene with better patient education materials to improve patients' health literacy, which may improve patients' medication adherence or transplant outcomes.

Education as a predictor of quality of life outcomes among disadvantaged men

Higher educational levels along with other factors such as literacy and communication with physicians have been associated with better outcomes for men with prostate cancer, but little research has focused on the relationship of educational attainment to self-efficacy for interacting with physicians been conducted on its effect on self-efficacy and health-related quality of life (HRQOL) among low-income, uninsured men. Data from 425 low-income, uninsured men with prostate cancer enrolled in UCLA's Men's Health Study were examined. We found that men with higher and lower education levels, including those who did not complete high school, had similar HRQOL and self-efficacy outcomes. Because of the close relationship between income and education, broader studies into the associations of these variables and prostate cancer outcomes are needed.

Sexual rehabilitation after localized prostate cancer: current interventions and future directions

Many published articles have documented the impact of prostate-cancer treatment on sexual functioning in men treated for localized disease. Surprisingly, the literature on interventions to rehabilitate men's sexual functioning is much more limited. In this article, we review the sexual-rehabilitation interventions for prostate-cancer patients and identify a number of common themes across interventions. We also identify areas where further research is needed and propose a conceptual model based on psychologic and nursing theories and informed by the published research.

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.

Limited literacy and psychiatric disorders among users of an urban safety-net hospital's mental health outpatient clinic

Little is known about the relationship between mental illness and literacy despite both being prevalent problems. We examine whether literacy varies by psychiatric diagnoses. Interviews and chart reviews (N = 100) were conducted in a behavioral health outpatient clinic. The relationships among sociodemographics, rapid estimate of adult literacy in medicine, measures of verbal and visual intellectual abilities, and psychiatric diagnoses were examined. The mean rapid estimate of adult literacy in medicine score was 55.9 which is equivalent to below an eighth grade literacy level. Psychotic disorder (p = 0.03) was associated with limited literacy, and substance abuse (p = 0.003) and PTSD (p = 0.07) were associated with higher literacy in bivariate analyses. These diagnoses were further examined in multivariate models. Limitations include the small sample size and the over-representation of people with high levels of education. Increasing our understanding of the relationships between health literacy and psychiatric disorders will help inform the development of appropriate psychiatric care and better outcomes.

Health Literacy and Health Actions: A Review and a Framework From Health Psychology

The association between performance on health literacy measures and health outcomes is well established. The next step is to understand the processes through which health literacy affects health. This review introduces a framework drawing on ideas from health psychology and proposing that associations between health literacy and health outcomes could be mediated by a range of health actions involving access and use of health care, patient—provider interactions, and the management of health and illness. The framework outlines routes through which health literacy might affect either health actions themselves or the motivational and volitional determinants that have been identified in social cognition models. The implications of the framework for future research and intervention strategies are discussed.

A Bayesian hierarchical modeling approach for studying the factors affecting the stage at diagnosis of prostate cancer

We extend the baseline-category logits model for categorical response data to accommodate two distinct kinds of clustering. Our extension introduces random effects that have one component exhibiting spatial dependence and a second component that is distributed independently. We use this enhanced categorical logits model for investigating the factors that affect the geographical distribution of the diagnostic stage of prostate cancer (PrCA) in South Carolina (SC). Using incidence data from the SC registry, we fit three types of models: the baseline-category logits model, the proportional odds model, and the adjacent-categories logits model, each incorporating our two-component random effects. The deviance information criterion (DIC) is used for selecting the best-fitting model. The results from the best model are presented and interpreted. The county-specific random effects are mapped to characterize the spatial distribution pattern of diagnostic stage of PrCA in the study region. In terms of spatial distribution of the diagnostic stage of PrCA, an area of excess (unexplained) risk was found in the north-west area, and an area of low excess risk in the north-east area for regional-stage cancer in SC was identified through the analysis of the cancer registry data.

Identifying the health and mental health information needs of people with coronary heart disease, with and without depression

OBJECTIVE

To identify the health and mental health information needs of people with coronary heart disease (CHD), with and without comorbid depression.

DESIGN AND SETTING

A qualitative study conducted in Melbourne in 2006, using thematic analysis of semi-structured interviews on the types of health information that patients with CHD considered useful to assist with the management of their illness. Structured clinical interviews were used to assess current and prior depressive episodes in these patients.

PARTICIPANTS

14 general practice patients (eight with current or prior history of major depression) who had experienced myocardial infarction, coronary artery bypass graft surgery, angioplasty or angina (confirmed via testing).

RESULTS

Four themes relating to information on how patients could manage their cardiovascular health and improve their psychosocial wellbeing emerged: psychosocial; physical activity; medical; and information for family. The most prominent information needs included identification and management of risk-related physical symptoms, and psychosocial information, most notably to enhance patients' social support. Patients considered this information important for alleviating health anxiety and negative affect.

CONCLUSION

This small patient sample endorsed the need for health and mental health information on a range of psychosocial and physical health topics. Participants desired specific types of information to assist with the self-management of their health and to assuage their health concerns.

Will patients agree to have their literacy skills assessed in clinical practice?

If health providers are aware of their patients' literacy skills, they can more appropriately tailor their communication with patients. Few providers, however, assess patient's literacy skills for fear of offending patients, but no research has ever determined if patients object to such assessments. Our objectives were to determine the percentage of patients seen for routine health care that would agree to undergo literacy assessment and if satisfaction of patients differs in practices that perform literacy assessments versus practices that do not. We randomized 20 private and public medical practices to an intervention group that implemented literacy assessments with the Newest Vital Sign and a control group that did not. For intervention practices, we noted the percentage of patients agreeing to undergo the assessment. For both intervention and control practices, we assessed patient satisfaction. Of 289 patients asked to undergo literacy assessment in the intervention practices, 284 (98.3%) agreed to do so, including 125 (46.1%) with low or possibly low literacy skills. There was no difference in satisfaction between the intervention group and the control group. We conclude that patients are willing to undergo literacy assessments during routine office visits and performing such assessments does not decrease patient satisfaction.

Provider and patient intervention to improve weight loss: a pilot study in a public hospital clinic

OBJECTIVE

To assess the efficacy of a literacy-appropriate weight loss intervention targeting providers and patients in improving physicians' weight loss counseling and patients' self-reported beliefs, and self-efficacy.

METHODS

The study took place in a public hospital nephrology clinic. The intervention included two physician workshops and a small group patient education. Physician-patient communication was observed and coded. Structured interviews assessed patient recall of weight loss recommendations, weight-related beliefs, and self-efficacy.

RESULTS

64 patient visits were observed before and after the intervention. 75% of patients were African American, 96% lacked private insurance, 71% had low literacy skills; mean body mass index (BMI) of 35 kg/m(2). Physician counseling improved significantly post-intervention, particularly in assessing, supporting and advising patients about weight loss and exercise. Patients reported increases in recall of weight loss recommendations and were more likely to report greater confidence about losing weight (52% vs. 70%, p<0.01).

CONCLUSIONS

This pilot study offers promising directions to address provider and patient barriers to weight loss education and counseling in a public hospital.

PRACTICE IMPLICATIONS

Hospital-based weight loss interventions need to target both physicians and patients.

Online cancer communication: meeting the literacy, cultural and linguistic needs of diverse audiences

OBJECTIVE

This article provides an analysis of issues and empirical evidence related to literacy, cultural, and linguistic factors in online health and cancer communication, and recommendations to improve cancer communication for diverse audiences.

METHODS

We examined English-language online literature and selected books and policy documents related to literacy, cultural, and linguistic factors in health and cancer communication.

RESULTS

Studies about literacy, cultural, and linguistic factors in online cancer communication for diverse audiences are limited, but have increased during the past 15 years. Empirical evidence and theoretical guidance describe the critical importance of these factors, significant unmet needs among low-literate, multicultural and non-English-speaking populations, and strategies to improve communication.

CONCLUSION

Overall, online cancer communication has not met the literacy, cultural, and linguistic needs of diverse populations. The literature offers valuable recommendations about enhancing research, practice, and policy for better cancer communication.

PRACTICE IMPLICATIONS

Practitioners should understand the strengths and weaknesses of online cancer communication for vulnerable groups, guide patients to better Websites, and supplement that information with oral and tailored communication.

Racial segregation and disparities in cancer stage for seniors

BACKGROUND

Disparities in cancer survival may be related to differences in stage. Segregation may be associated with disparities in stage, particularly for cancers for which screening promotes survival.

OBJECTIVES

The objective of the study was to examine whether segregation modifies racial/ethnic disparities in stage.

DESIGN

The design of the study was analysis of Surveillance, Epidemiology, and End Results Medicare data for seniors with breast, colorectal, lung, and prostate cancer (n = 410,870).

MEASUREMENTS AND MAIN RESULTS

The outcome was early- versus late-stage diagnosis. Area of residence was categorized into 4 groups: low segregation/high income (potentially the most advantaged), high segregation/high income, low segregation/low income, and high segregation/low income (possibly the most disadvantaged). Blacks were less likely than whites to be diagnosed with early-stage breast, colorectal, or prostate cancer, regardless of area. For colorectal cancer, the black/white disparity was largest in low-segregation/low-income areas (black/white odds ratio [OR] of early stage 0.51) and smallest in the most segregated areas (ORs 0.71 and 0.74, P < .005). Differences in disparities in stage by area category were not apparent for breast, prostate, or lung cancer. Whereas there were few Hispanic-white differences in early-stage diagnosis, the Hispanic/white disparity in early-stage diagnosis of breast cancer was largest in low-segregation/low-income areas (Hispanic/white OR of early stage 0.54) and smallest in high-segregation/low-income areas (OR 0.96, P < .05 compared to low-segregation/low-income areas).

CONCLUSIONS

Disparities in stages for cancers with an established screening test were smaller in more segregated areas.

Insurance and quality of life in men with prostate cancer: data from the Cancer of the Prostate Strategic Urological Research Endeavor

OBJECTIVE

To evaluate the effect of medical insurance coverage on health-related quality of life (HRQoL) outcomes in men newly diagnosed with prostate cancer, as insurance status has been shown to be related to clinical presentation, and types of treatments received for localized prostate cancer, but the relationship of insurance and QoL has not been explored sufficiently.

PATIENTS AND METHODS

Data from the Cancer of the Prostate Strategic Urological Research Endeavor (CaPSURE), a national longitudinal database registry of men with prostate cancer, were used for this study. Men who were newly diagnosed at entry to CaPSURE and completed one questionnaire before treatment, and one or more afterwards, were included. Insurance groups specific to age distribution of the study population were assessed, i.e. Medicare, preferred provider organizations (PPOs), health maintenance organizations (HMOs), fee for service (FFS), and the Veterans Administration (VA) for the younger group, and Medicare only, Medicare plus supplement (+S), and HMO/PPO for the older group. Associations between patients' clinical and sociodemographic characteristics and insurance status were evaluated by chi-square and analysis of variance. Relationships between insurance status and HRQoL outcomes over time were evaluated by multivariate mixed model.

RESULTS

Of 2258 men who met the study criteria, 1259 were younger and 999 were older than 65 years. More than half of the younger patients belonged to an HMO or PPO (42.2% and 32.5%, respectively), with the remainder distributed between Medicare, FFS and VA. In the older group most men belonged to Medicare only and the Medicare +S groups (22.4% and 58.8%, respectively). There was greater variation in clinical risk categories at presentation by insurance groups in the younger group. In the multivariate analysis, insurance status was significantly associated with changes in most HRQoL outcomes over time in the younger group, while in the older patients the effect of insurance diminished. Men in the VA and Medicare systems had lower scores at baseline and a steeper decline in Physical Function, Role Physical, Role Emotional, Social Function, Bodily Pain, Vitality, and General Health domains over time, controlling for type of initial treatment received, timing of HRQoL assessment, number of comorbidities, clinical risk at presentation, and income.

CONCLUSION

Insurance was independently related to changes in a wide range of HRQoL outcomes in men aged <65 years treated for prostate cancer. With the latest advances in early diagnosis and treatment of prostate cancer, clinicians and researchers should be aware of the specific groups of patients who are more vulnerable to the adverse effects of treatment and subsequent decline in functioning. The present findings could provide important tools for understanding the process of recovery after treatment for prostate cancer, and identifying needs for specific services.
