Associations between perceived discrimination over the life course, subjective social status, and health literacy: A racial/ethnic stratification analysis

Objective

To analyze the relationship between perceived discrimination over the life course, social status, and limited health literacy (HL).

Methods

5040 adults who participated in the 2023 Survey of Racism and Public Health. We applied stratified multilevel models adjusted for sociodemographic characteristics.

Results

The average age was 47 years, 48% identified as White, 20% as Latinx, and 17% as Black. In the overall sample, we observed associations of perceived discrimination (b = 0.05, 95% CI: 0.01, 0.09), subjective social status (b = -0.16, 95% CI: -0.23, -0.10), and their interaction (b = 0.02, 95% CI: 0.01, 0.03). More perceived discrimination was associated with lower HL in the White and Multiracial participants. Higher subjective social status was associated with higher HL in the White and Latinx participants. There was a statistically significant interaction between perceived discrimination and subjective social status on HL among the White, Latinx, and Multiracial participants.

Conclusion

This analysis has implications for public health practice, indicating that multi-level interventions are needed to address limited HL.

Innovation

Our findings provide novel insights for identifying key SDOH indicators to assess in clinical settings to provide health literate care.

Racial Composition of Social Environments Over the Life Course Using the Pictorial Racial Composition Measure: Development and Validation Study

BACKGROUND

Studies investigating the impact of racial segregation on health have reported mixed findings and tended to focus on the racial composition of neighborhoods. These studies use varying racial composition measures, such as census data or investigator-adapted questions, which are currently limited to assessing one dimension of neighborhood racial composition.

OBJECTIVE

This study aims to develop and validate a novel racial segregation measure, the Pictorial Racial Composition Measure (PRCM).

METHODS

The PRCM is a 10-item questionnaire of pictures representing social environments across adolescence and adulthood: neighborhoods and blocks (adolescent and current), schools and classrooms (junior high and high school), workplace, and place of worship. Cognitive interviews (n=13) and surveys (N=549) were administered to medically underserved patients at a primary care clinic at the Barnes-Jewish Hospital. Development of the PRCM occurred across pilot and main phases. For each social environment and survey phase (pilot and main), we computed positive versus negative pairwise comparisons: mostly Black versus all other categories, half Black versus all other categories, and mostly White versus all other categories. We calculated the following validity metrics for each pairwise comparison: sensitivity, specificity, correct classification rate, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, false positive rate, and false negative rate.

RESULTS

For each social environment, the mostly Black and mostly White dichotomizations generated better validity metrics relative to the half Black dichotomization. Across all 10 social environments in the pilot and main phases, mostly Black and mostly White dichotomizations exhibited a moderate-to-high sensitivity, specificity, correct classification rate, positive predictive value, and negative predictive value. The positive likelihood ratio values were >1, and the negative likelihood ratio values were close to 0. The false positive and negative rates were low to moderate.

CONCLUSIONS

These findings support that using either the mostly Black versus other categories or the mostly White versus other categories dichotomizations may provide accurate and reliable measures of racial composition across the 10 social environments. The PRCM can serve as a uniform measure across disciplines, capture multiple social environments over the life course, and be administered during one study visit. The PRCM also provides an added window into understanding how structural racism has impacted minoritized communities and may inform equitable intervention and prevention efforts to improve lives.

Choice Consistency in Discrete Choice Experiments: Does Numeracy Skill Matter?

OBJECTIVES

This study investigated the relationship between numeracy skills (NS) and choice consistency in discrete choice experiments (DCEs).

METHODS

A DCE was conducted to explore patients' preferences for kidney transplantation in Italy. Patients completed the DCE and answered 3-item numeracy questions. A heteroskedastic multinomial logit model was used to investigate the effect of numeracy on choice consistency.

RESULTS

Higher NS were associated with greater choice consistency, increasing the scale to 1.63 (P < .001), 1.39 (P < .001), and 1.18 (P < .001) for patients answering 3 of 3, 2 of 3, and 1 of 3 questions correctly, respectively, compared with those with no correct answers. This corresponded to 63%, 39%, and 18% more consistent choices, respectively. Accounting for choice consistency resulted in varying willingness-to-wait (WTW) estimates for kidney transplant attributes. Patients with the lowest numeracy (0/3) were willing to wait approximately 42 months [95% CI: 29.37, 54.68] for standard infectious risk, compared with 33 months [95% CI: 28.48, 38.09] for 1 of 3, 28 months [95% CI: 25.13, 30.32] for 2 of 3, and 24 months [95% CI: 20.51, 27.25] for 3 of 3 correct answers. However, WTW differences for an additional year of graft survival and neoplastic risk were not statistically significant across numeracy levels. Supplementary analyses of 2 additional DCEs on COVID-19 vaccinations and rheumatoid arthritis, conducted online, supported these findings: higher NS were associated with more consistent choices across different disease contexts and survey formats.

CONCLUSIONS

The findings suggested that combining patients with varying NS could bias WTW estimates, highlighting the need to consider numeracy in DCE data analysis and interpretation.

Clinical Assessment of Judgment in Adults and the Elderly: Development and Validation of the Three Domains of Judgment Test-Clinical Version (3DJT-CV)

(1) Background: This article discusses the first two phases of development and validation of the Three Domains of Judgment Test (3DJT). This computer-based tool, co-constructed with users and capable of being administered remotely, aims to assess the three main domains of judgment (practical, moral, and social) and learn from the psychometric weaknesses of tests currently used in clinical practice. (2) Method: First, we presented the 3DJT to experts in cognition, who evaluated the tool as a whole as well as the content validity, relevance, and acceptability of 72 scenarios. Second, an improved version was administered to 70 subjects without cognitive impairment to select scenarios with the best psychometric properties in order to build a future clinically short version of the test. (3) Results: Fifty-six scenarios were retained following expert evaluation. Results support the idea that the improved version has good internal consistency, and the concurrent validity primer shows that 3DJT is a good measure of judgment. Furthermore, the improved version was found to have a significant number of scenarios with good psychometric properties to prepare a clinical version of the test. (4) Conclusion: The 3DJT is an interesting alternative tool for assessing judgment. However, more studies are needed for its implementation in a clinical context.

Breast cancer patients' visual attention to information in hospital report cards: An eye-tracking study on differences between younger and older female patients

To (1) explore how women visually attend to a hospital report card (HRC), (2) explore whether visual attention of younger and older women (patients and non-patients) differs. Eye-tracking study with a short survey. Participants (N = 37) were provided with a hypothetical realistic HRC. Total dwell times and fixation counts were measured while participants viewed the information. Overall, no differences existed between younger and older women. Visual attention to the hospital of choice (vs not of choice) and to indicators perceived as most important (vs least important) did not differ. However, women with higher health literacy looked longer at the HRC than women with lower health literacy. Also, per fixation, older patients (vs younger patients) looked longer at the hospital of choice and at indicators perceived most important. Pre-existing conceptions of what information is relevant might result in more in-depth information processing among older patients than younger patients. In general, differences in level of health literacy, rather than (chronological) age, seem to be relevant to take into account when designing and/or updating HRCs.

Sharpening, focusing, and developing: A study of change in nonsymbolic number comparison skills and math achievement in 1st grade

Children's ability to discriminate nonsymbolic number (e.g., the number of items in a set) is a commonly studied predictor of later math skills. Number discrimination improves throughout development, but what drives this improvement is unclear. Competing theories suggest that it may be due to a sharpening numerical representation or an improved ability to pay attention to number and filter out non-numerical information. We investigate this issue by studying change in children's performance (N = 65) on a nonsymbolic number comparison task, where children decide which of two dot arrays has more dots, from the middle to the end of 1st grade (mean age at time 1 = 6.85 years old). In this task, visual properties of the dot arrays such as surface area are either congruent (the more numerous array has more surface area) or incongruent. Children rely more on executive functions during incongruent trials, so improvements in each congruency condition provide information about the underlying cognitive mechanisms. We found that accuracy rates increased similarly for both conditions, indicating a sharpening sense of numerical magnitude, not simply improved attention to the numerical task dimension. Symbolic number skills predicted change in congruent trials, but executive function did not predict change in either condition. No factor predicted change in math achievement. Together, these findings suggest that nonsymbolic number processing undergoes development related to existing symbolic number skills, development that appears not to be driving math gains during this period. Children's ability to discriminate nonsymbolic number improves throughout development. Competing theories suggest improvement due to sharpening magnitude representations or changes in attention and inhibition. The current study investigates change in nonsymbolic number comparison performance during first grade and whether symbolic number skills, math skills, or executive function predict change. Children's performance increased across visual control conditions (i.e., congruent or incongruent with number) suggesting an overall sharpening of number processing. Symbolic number skills predicted change in nonsymbolic number comparison performance.

Health literacy on oral health practice and condition in an adult and elderly population

The objective of this study was to investigate the impact of health literacy (HL) on health practices and oral health outcomes in an adult and elderly population in Brazil. A cross-sectional study nested in a cohort study was followed up over a period of four years (2011 and 2015) and assessed individuals between 23 and 69 years old from Piracicaba, São Paulo, Brazil. Data were collected by means of oral examinations (coronal caries, periodontal disease and visible biofilm) and interviews (socioeconomic, demographic, oral health-related quality of life, health practices and HL). The 14-item Health Literacy Scale (HLS) was used for HL data, which was the main explanatory variable. The result of the sum of the HLS-14 questionnaire for each participant was dichotomized into the median (46 points): 'high' and 'low' HL. Binary/multinomial logistic regressions were performed on health practice and oral health outcomes, controlled by age and sex (Model 1) and age, sex and socioeconomic status (Model 2; p < 0.05). The final sample consisted of 137 subjects and 43.8% (n = 60) presented low HL (LHL). LHL was associated with health practices, such as use of public dental services in Model 1 (odds ratio [OR] = 0.34, 95% CI: 0.14-0.87) and use of dental services for emergency in Model 1 (OR = 2.69, 95% CI: 1.29-5.51) and Model 2 (OR = 2.93, 95% CI: 1.17-7.30). Based on age and sex, LHL was associated with use of public dental service and use of emergency dental visits. Based on age, sex and socioeconomic status, LHL was associated with use of emergency dental visits.

Low Health Literacy Is Associated With Frailty and Reduced Likelihood of Liver Transplant Listing: A Prospective Cohort Study

The effect of low health literacy (HL) on outcomes in end-stage liver disease (ESLD) is largely unknown. The association of low HL on clinical outcomes was investigated in a prospective cohort of outpatients with ESLD undergoing liver transplantation (LT) evaluation. From 2014 to 2017, 276 patients underwent LT evaluation with assessments of liver disease severity, medical and psychosocial comorbidities, physical frailty, and malnutrition. Literacy was measured with the Newest Vital Sign, a brief validated assessment. Multivariate models assessed relationships between HL and clinical outcomes adjusting for clinical and psychosocial variables. The median Model for End-Stage Liver Disease-sodium score of the study sample was 15 (interquartile range, 11-19), 71 (25.7%) of candidates were frail, 117 (42.4%) had malnutrition, 151 (54.7%) had hepatic encephalopathy, 104 (37.7%) had low HL, and 85 (39.2%) had marginal or poor social support. Adjusting for education level, socioeconomic factors, and severity of illness, low HL was independently associated with physical frailty (adjusted odds ratio [aOR], 3.59; 95% confidence interval [CI], 1.50-8.59; P = 0.004) and not being wait-listed (aOR 1.96; 95% CI, 1.03-3.75; P = 0.04). Strong social support attenuated the relationship between low HL and not being wait-listed (aOR, 1.58; 95% CI, 0.74-3.36; P = 0.24). Low HL is common and a largely unrecognized risk factor for poor health outcomes among patients with ESLD. Patient-oriented infrastructure and support are needed at the health system level to ensure all patients can successfully navigate the complex process of LT evaluation and wait-listing.

Health literacy: Prevalence and determinants in Lagos State, Nigeria

Background

Poor health literacy has been associated with poorer physical and mental health function, and higher emergency department and hospital utilizations. The study was conducted to measure the prevalence of health literacy and its determinants among Lagos State residents.

Methods

A descriptive cross-sectional study was conducted in three local government areas in Lagos State. Health literacy was assessed using the Brief Health Literacy Screening tool (BHLS), a three-item tool with possible scores ranging between 3 and 15. Health literacy was classified as inadequate (≤ 9) or adequate (>9).

Results

A total of 1831 respondents participated in the study, among whom, 952 (52%) were women. The mean age of respondents was 31.7 (±10.5) years. Three-quarters (74.8%) of respondents had adequate health literacy. Adequate levels of health literacy were associated with being female (OR, 1.35; 95% CI, 1.07–1.71), frequent use of the broad cast media as source of information (OR, 1.33; 95% CI, 1.03–1.70), frequent use of the internet as source of information (OR, 1.49; 95% CI, 1.13–1.96). Adequate health literacy was also associated with having knowledge of a frequently prescribed antibiotic (OR, 1.67; 95% CI, 1.32–2.12) and being more comfortable with the use of the English language (OR, 1.71; 95% CI, 1.32–2.22).

Conclusion

Gender, the use of broadcast media and the internet are predictive of adequate health literacy and should be taken into consideration in planning health interventions.

Translation, cross-cultural adaptation and psychometric evaluation of Brazilian Portuguese version of the 14-item Health Literacy Scale

We evaluated the psychometric properties of the Health Literacy Scale - 14 (HLS-14), the Brazilian Portuguese version. In the methodological study with a cross-sectional design, the following were performed: translation, cross-cultural adaptation and evaluation of the psychometric properties. After being subjected to a committee of experts, translated and adapted, the instrument was pre-tested with 52 adults and applied to 143 adults and older people of Piracicaba-SP. Internal consistency was assessed based on the Kendall correlation coefficient and Cronbach's alpha (>0.70), and the confirmatory factor analysis (CFA) was conducted using the chi-square test, the Standardized Residual Mean Square Root (SRMR), the Root Mean Square Error of Approximation (RMSEA) (<0.05), the Comparative Fit Index (CFI) (>0.95) and the Tucker-Lewis Index (TLI) (>0.95). The analysis of operational equivalence showed agreement between most of the questions, exception questions 6, 8, 9 and 14. Cronbach's alpha was 0.82. There was reasonable adjustment in the CFA: CFI=0.886, TLI=0.86, RMSEA=0.085 (90%CI: 0.065-0.105), SRMR=0.071, chi-square (74 degrees of freedom) = 149.510, p<0.001. The exclusion of question 5 increased the adjustment level to satisfactory. The Brazilian Portuguese version of HLS-14 can be considered a valid health literacy assessment instrument.

On selecting quality indicators: preferences of patients with breast and colon cancers regarding hospital quality indicators

Background

There is an increasing number of quality indicators being reported publicly with aim to improve the transparency on hospital care quality. However, they are little used by patients. Knowledge on patients’ preferences regarding quality may help to optimise the information presented to them.

Objective

To measure the preferences of patients with breast and colon cancers regarding publicly reported quality indicators of Dutch hospital care.

Methods

From the existing set of clinical quality indicators, participants of patient group discussions first assessed an indicator’s suitability as choice information and then identified the most relevant ones. We used the final selection as attributes in two discrete choice experiments (DCEs). Questionnaires included choice vignettes as well as a direct ranking exercise, and were distributed among patient communities. Data were analysed using mixed logit models.

Results

Based on the patient group discussions, 6 of 52 indicators (breast cancer) and 5 of 21 indicators (colon cancer) were selected as attributes. The questionnaire was completed by 84 (breast cancer) and 145 respondents (colon cancer). In the patient group discussions and in the DCEs, respondents valued outcome indicators as most important: those reflecting tumour residual (breast cancer) and failure to rescue (colon cancer). Probability analyses revealed a larger range in percentage change of choice probabilities for breast cancer (10.9%–69.9%) relative to colon cancer (7.9%–20.9%). Subgroup analyses showed few differences in preferences across ages and educational levels. DCE findings partly matched with those of direct ranking.

Conclusion

Study findings show that patients focused on a subset of indicators when making their choice of hospital and that they valued outcome indicators the most. In addition, patients with breast cancer were more responsive to quality information than patients with colon cancer.

Association between numeracy and self-rated poor health in 33 high- and upper middle- income countries

The association between numeracy proficiency and health outcomes has been the subject of several studies. However, it is not known if this association is independent of educational attainment and literacy proficiency. In this study, we used logistic regression to model numeracy proficiency as a predictor of self-rated poor health after accounting for educational attainment and literacy proficiency. The prevalence of self-rated poor health among 166,863 adults aged 16-65 years from 33 high- and upper middle-income countries was 24%. Compared to those with the highest numeracy proficiency (level 4), the odds ratio of self-rated poor health for those with the lowest numeracy proficiency (level 1) was 2.2 (95% CI 1.9-2.7) and attenuated to 1.8 (95% CI 1.5-2.1) and 1.5 (95% CI 1.1, 2.0), respectively, after sequential addition of self-education and literacy proficiency. For those who were assessed to have low levels of both numeracy and literacy proficiency, the odds ratio of self-rated poor health was 1.4 (95% CI 1.3 to 1.5), relative to those who had high levels of both numeracy and literacy proficiencies. Numeracy and literacy proficiencies show both independent and interdependent correlations with poor self-rated health. Further, these associations varied by sociodemographic characteristics and across countries. Policies aimed at improving numeracy and literacy may be beneficial in preventing adverse health outcomes.

Challenging the neurobiological link between number sense and symbolic numerical abilities

A significant body of research links individual differences in symbolic numerical abilities, such as arithmetic, to number sense, the neurobiological system used to approximate and manipulate quantities without language or symbols. However, recent findings from cognitive neuroscience challenge this influential theory. Our current review presents an overview of evidence for the number sense account of symbolic numerical abilities and then reviews recent studies that challenge this account, organized around the following four assertions. (1) There is no number sense as traditionally conceived. (2) Neural substrates of number sense are more widely distributed than common consensus asserts, complicating the neurobiological evidence linking number sense to numerical abilities. (3) The most common measures of number sense are confounded by other cognitive demands, which drive key correlations. (4) Number sense and symbolic number systems (Arabic digits, number words, and so on) rely on distinct neural mechanisms and follow independent developmental trajectories. The review follows each assertion with comments on future directions that may bring resolution to these issues.

Public reporting of hospital performance data: views of senior medical directors in Victoria, Australia

Objective The aim of the present study was to better understand senior medical directors' perceptions of public reporting of hospital performance data, how public reporting affects institutional behavioural change towards quality improvement and how it could be improved. Methods Interviews were undertaken with 17 medical directors representing 26 metropolitan and regional public hospitals in Victoria, Australia, between June and August 2016. Data were analysed thematically. Results Medical directors are well placed to comment on clinical and administrative aspects of quality, safety and performance monitoring in public hospitals. Their responses largely suggested that public reporting of hospital performance data in Australia is immature and not fulfilling its potential. There was little consensus among informants around what public reporting is, who it is for or its purpose. Although public reporting was considered to have important functions for hospitals and consumers, it was generally considered to lack robustness and have underutilised potential to inform consumers, build trust and drive quality and performance improvements within hospitals. Conclusions The next steps needed to advance public reporting of hospital performance data in Australia include engaging clinicians and patients in selection and development of metrics, improving timeliness of reporting, and improving communication of information so that it is accessible and meaningful for different audiences. What is known about the topic? Public reporting of hospital performance data is a mechanism increasingly used in the Australian health system, but it has attracted little research. What does this paper add? This paper reveals a lack of shared understanding among medical directors in Victoria, Australia, on what public reporting of hospital performance data is, who it is for and its purpose. The paper highlights the potential importance of public reporting of hospital performance data for rural and regional healthcare consumers and how it may be strengthened. What are the implications for practitioners? Stronger systems of public reporting of hospital performance data have the potential to increase consumer engagement and improve hospital performance, quality and safety. Awareness of the discourse around public reporting of hospital performance data can increase practitioners' engagement in debate and development of reporting systems.

The Roles of Education, Literacy, and Numeracy in Need for Health Information during the Second Half of Adulthood: A Moderated Mediation Analysis

We examine complex pathways that link health information seeking behavior with education and health literacy (decomposed into general literacy and numeracy), and how these pathways differ by perceived health status (need) among a nationally representative sample of Americans age 50 and older (n = 2,750). Data come from the Program for International Assessment of Adult Competencies (PIAAC). Multi-group structural equation models were used to examine the use of eight health information sources (newspapers, magazines, internet, radio, TV, books, friends/family, and health professionals). Findings partially support the long-standing notion that health seeking behaviors are directly linked to educational attainment, and provide some of the first nationally representative evidence for how education functions through distinct health literacy components to shape health information seeking behaviors by health status. Findings from this moderated mediation analysis point to the importance of examining, and addressing, health literacy disparities in access to and use of health information.

Attention to number: The convergence of numerical magnitude processing, attention, and mathematics in the inferior frontal gyrus

Research indicates that the neurocognitive system representing nonsymbolic numerical magnitudes is foundational for the development of mathematical competence. However, recent studies found that the most common task used to measure numerical acuity, the nonsymbolic number comparison task, is heavily influenced by non-numerical visual parameters of stimuli that increase executive function demands. Further, this influence may be a confound invalidating theoretical accounts of the relation between number comparison performance and mathematical competence. Instead of acuity, the relation may depend on one's ability to attend to numerical information in the face of competing, non-numerical cues. The current study investigated this issue by measuring neural activity associated with numerical magnitude processing acuity, domain-general attention, and selective attention to number via functional magnetic resonance imaging while children 8-11 years old completed a nonsymbolic number comparison task and a flanker task. Results showed that activation in the right inferior frontal gyrus during incongruent versus congruent trials of the comparison task, our construct for attention to number, predicted mathematics achievement after controlling for verbal IQ, flanker accuracy rate, and the neural congruency effect from the flanker task. In contrast, activity in frontal and parietal regions responding to differences in difficulty of numerical comparisons, our construct for numerical magnitude processing acuity, did not correlate with achievement. Together, these findings suggest a need to reframe existing models of the relation between number processing and math competence to include the interaction between attention and use of numerical information, or in other words "attention to number."

Dyscalculia and Typical Math Achievement Are Associated With Individual Differences in Number-Specific Executive Function

Deficits in numerical magnitude perception characterize the mathematics learning disability developmental dyscalculia (DD), but recent studies suggest the relation stems from inhibitory control demands from incongruent visual cues in the nonsymbolic number comparison task. This study investigated the relation among magnitude perception during differing congruency conditions, executive function, and mathematics achievement measured longitudinally in children (n = 448) from ages 4 to 13. This relation was investigated across achievement groups and as it related to mathematics across the full range of achievement. Only performance on incongruent trials related to achievement. Findings indicate that executive function in a numerical context, beyond magnitude perception or executive function in a non-numerical context, relates to DD and mathematics across a wide range of achievement.

The effect of cost-sharing design characteristics on use of health care recommended by the treating physician; a discrete choice experiment

BACKGROUND

Cost-sharing programs are often too complex to be easily understood by the average insured individual. Consequently, it is often difficult to determine the amount of expenses in advance. This may preclude well-informed decisions of insured individuals to adhere to medical treatment advised by the treating physician. Preliminary research has showed that the uncertainty in these cost-sharing payments are affected by four design characteristics, i.e. 1) type of payments (copayments, coinsurances or deductibles), 2) rate of payments, 3) annual caps on cost-sharing and 4) moment that these payments must be made (directly at point of care or billed afterwards by the insurer).

METHODS

An online discrete choice experiment was used to assess the extent to which design characteristics of cost-sharing programs affect the decision of individuals to adhere to recommended care (prescribed medications, ordered diagnostic tests and referrals to medical specialist care). Analyses were performed using mixed multinomial logits.

RESULTS

The questionnaire was completed by 7921 members of a patient organization. Analyses showed that 1) cost-sharing programs that offer clear information in advance on actual expenses that are billed afterwards, stimulate adherence to care recommended by the treating physician; 2) the relative importance of the design characteristics differed between respondents who reported to have forgone health care due to cost-sharing and those who did not; 3) price-awareness among respondents was limited; 4) the utility derived from attributes and respondents' characteristics were positively correlated; 5) an optimized cost-sharing program revealed an adherence of more than 72.9% among those who reported to have forgone health care.

CONCLUSIONS

The analyses revealed that less complex cost-sharing programs stimulate adherence to recommended care. If these programs are redesigned accordingly, individuals who had reported to have forgone a health service recommended by their treating physician due to cost-sharing, would be more likely to use this service. Such redesigned programs provide a policy option to reduce adverse health effects of cost-sharing in these groups. Considering the upcoming shift from volume-based to value-based health care provision, insights into the characteristics of a cost-sharing program that stimulates the use of recommended care may help to design value-based insurance plans.

Impact of public release of performance data on the behaviour of healthcare consumers and providers

BACKGROUND

It is becoming increasingly common to publish information about the quality and performance of healthcare organisations and individual professionals. However, we do not know how this information is used, or the extent to which such reporting leads to quality improvement by changing the behaviour of healthcare consumers, providers, and purchasers.

OBJECTIVES

To estimate the effects of public release of performance data, from any source, on changing the healthcare utilisation behaviour of healthcare consumers, providers (professionals and organisations), and purchasers of care. In addition, we sought to estimate the effects on healthcare provider performance, patient outcomes, and staff morale.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, and two trials registers on 26 June 2017. We checked reference lists of all included studies to identify additional studies.

SELECTION CRITERIA

We searched for randomised or non-randomised trials, interrupted time series, and controlled before-after studies of the effects of publicly releasing data regarding any aspect of the performance of healthcare organisations or professionals. Each study had to report at least one main outcome related to selecting or changing care.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened studies for eligibility and extracted data. For each study, we extracted data about the target groups (healthcare consumers, healthcare providers, and healthcare purchasers), performance data, main outcomes (choice of healthcare provider, and improvement by means of changes in care), and other outcomes (awareness, attitude, knowledge of performance data, and costs). Given the substantial degree of clinical and methodological heterogeneity between the studies, we presented the findings for each policy in a structured format, but did not undertake a meta-analysis.

MAIN RESULTS

We included 12 studies that analysed data from more than 7570 providers (e.g. professionals and organisations), and a further 3,333,386 clinical encounters (e.g. patient referrals, prescriptions). We included four cluster-randomised trials, one cluster-non-randomised trial, six interrupted time series studies, and one controlled before-after study. Eight studies were undertaken in the USA, and one each in Canada, Korea, China, and The Netherlands. Four studies examined the effect of public release of performance data on consumer healthcare choices, and four on improving quality.There was low-certainty evidence that public release of performance data may make little or no difference to long-term healthcare utilisation by healthcare consumers (3 studies; 18,294 insurance plan beneficiaries), or providers (4 studies; 3,000,000 births, and 67 healthcare providers), or to provider performance (1 study; 82 providers). However, there was also low-certainty evidence to suggest that public release of performance data may slightly improve some patient outcomes (5 studies, 315,092 hospitalisations, and 7502 providers). There was low-certainty evidence from a single study to suggest that public release of performance data may have differential effects on disadvantaged populations. There was no evidence about effects on healthcare utilisation decisions by purchasers, or adverse effects.

AUTHORS' CONCLUSIONS

The existing evidence base is inadequate to directly inform policy and practice. Further studies should consider whether public release of performance data can improve patient outcomes, as well as healthcare processes.

Influence of ethnicity, gender, and immigration status on millennials’ behavior related to seeking health information

Purpose

The purpose of this paper is to understand the behavior diversities that exist among young millennials’ subgroups in ways they seek health-related information.

Design/methodology/approach

The authors ran several sets of analyses on the 2012–2014 US Program for the International Assessment of Adult Competencies (PIAAC) Data using Stata. The population was stratified into four specific subgroups based on their gender, ethnicity—blacks, Hispanics and whites—immigration status, college status—whether they were enrolled in a program of study at the time of the survey. The outcome variables were sources of health information including print (books/magazines/brochures), traditional media (Radio/TV), internet, family/friends/co-workers and health professionals. The independent variables were gender, ethnicity, educational status and immigration status. The authors utilized the appropriate sample weight derived by Organization for Economic Cooperation and Development so the findings can be generalized to the populations. The analysis included several descriptive statistics and χ2 test of independence.

Findings

Despite similarities, young adults’ health seeking behavior is complex influenced by gender, ethnicity, immigration status and education. The results indicated that while the internet is the primary source of health-related information for all young adults, there are subtle differences in utilizing other available resources. For example while more educated young adults seek help from their family members, the less educated peers use the media to obtain health-related information. Ethnicity has also an effect on young adults’ information seeking behavior. The number of Hispanics and blacks that obtain their information from traditional media is significantly higher than their white counterparts.

Research limitations/implications

This study has several limitations. First, the authors did not consider the effect of young adults’ digital literacy skills, problem solving skills and numeracy skills on their health seeking approach. Including these cognitive skills could reveal key information about young adults approach to information seeking that is not apparent by race, ethnicity and gender only. Another limitation of this study is the lack of the ability to claim causation, PIAAC data are designed strictly for cross-sectional analysis.

Practical implications

Although, behaviors often do not change simply by presenting information, trying to change behavior without improving individuals’ understanding of the issue by providing accurate information is likely to fail. Providing standardized health-related information sources that are accessible to all is vitally important. The results indicate that while the majority of young adults use the internet as their primary source of information only a few percentage of young adults seek information from health professional. Consequently, there is a need for an easily accessible and standardized online health-related source of information.

Social implications

Healthcare facilities and health related industries have the resources and the ability to develop a reliable infrastructure that could potentially provide reliable information that is easy to understand and navigate for adults with a variety of literacy and skills to use. Perhaps adopting the Universal Design for Learning approach and providing information that is accessible to a variety of individuals regardless of their education, learning skills and language skills. Flexible learning resources provided within a standard infrastructure accessible to all can help individuals find trustworthy and consistent information that they can trust.

Originality/value

Despite the unique characteristics of the millennials and the profound change in the way young adults seek information, there is a paucity of research on the ways young adults seek health-related information. Most existing literature is based on locally developed surveys and convenient sampling with limited reliability and validity information. Consequently making a sweeping statement based on their findings is considered as hasty generalization. The PIAAC, on the other hand, is a nationally representative data, extensively examined for its validity and reliability.

Beyond Reading and Understanding: Health Literacy as the Capacity to Act

Many health literacy interventions have a limited focus on functional/cognitive skills. In psychosocial models, the capacity to act however is seen as a major driver of behavioural change. This aspect is often lacking in health literacy concepts. In this study, we examine the impact of both aspects of health literacy (functional/cognitive and capacity to act) on specific healthcare outcomes (healthcare use, experiences with patient-centered care, shared-decision making, and self-management). In a sample of a national panel of people with a chronic disease (NPCD), questions about health literacy, patient activation, and outcomes were asked. The results indicated that 39.9% had limited HL levels and 36.9% had a low activation score. Combined, 22.7% of the sample scored low on both aspects, whereas 45.8% had adequate levels on both. Patients who score low on both use more healthcare and have less positive experiences with patient-centered care, shared decision making, and self-management. Patients who have adequate competency levels in both respects have the best outcomes. Both cognitive and non-cognitive aspects of health literacy are important, and they enhance each other. The capacity to act is especially important for the extent to which people feel able to self-manage.

When do people choose to be informed? Predictors of information-seeking in the choice of primary care provider in Sweden

Improving the ability of patients to make informed choices of health care provider can give providers more incentive to compete based on quality. Still, it is not evident to what extent and when people search for information when choosing a provider. The aim of this study is to identify under what circumstances individuals seek information when choosing a primary care provider. Research to date has mostly focused on individuals' demographic and socio-economic characteristics and the poor availability of information as barriers to information-seeking and use. Our results highlight the importance of taking individuals' personal motivations and situational context into account when studying information-seeking behavior. Overall, these results suggest that not even individuals who are likely to search for information since they switched or considered switching primary care provider, do so to any greater extent. However, those motivated to change providers by internal factors such as dissatisfaction or a belief that other providers may provide superior services actively sought out information to a greater extent than those motivated by external factors such as the closure of their current provider, or by moving house. Gender, employment status, place of residence and education level was also significantly associated with information-seeking.

What Patients Look for When Browsing Online for Pancreatic Cancer: The Bait Behind the Byte

BACKGROUND

Suitability is a patient-centered metric defined as how appropriately health information is targeted to specific populations to increase knowledge. However, suitability is most commonly evaluated exclusively by healthcare professionals without collaboration from intended audiences. Suitability (as rated by intended audiences), accuracy and readability have not been evaluated on websites discussing pancreatic cancer.

METHODS

Ten healthy volunteers evaluated fifty pancreatic cancer websites using the suitability assessment of materials (SAM instrument) for the materials' overall suitability. Readability and accuracy were correlated.

RESULTS

Ten recruited volunteers (ages 23-63, 50% female) found websites to be on average "adequate" or "superior" in suitability. Surgery, radiotherapy and nonprofit websites had higher suitability scores as compared to counterparts (p ≤ 0.03). There was no correlation between readability and accuracy levels and suitability scores (p ≥ 0.3). Presence of visual aids was associated with better suitability scores after controlling for website quality (p ≤ 0.01).

CONCLUSION

Suitability of websites discussing pancreatic cancer treatments as rated by lay audiences differed based on therapy type and website affiliation, and was independent of readability level and accuracy of information. Nonprofit affiliation websites focusing on surgery or radiotherapy were most suitable. Online information should be assessed for suitability by target populations, in addition to readability level and accuracy, to ensure information reaches the intended audience.

Description of YESHealth: A consumer-directed intervention in a randomized trial of methods to improve quality of care for persons with disability

BACKGROUND

Persons leading their own evaluations of care quality offers the promise of generating maximally meaningful information to ensure person-centered care.

OBJECTIVES

To describe an intervention where persons with disability engage other persons with disability, develop their own metrics to assess their care, and provide these care evaluations directly to primary care practitioners, with the goal of improving care. The context was a research study involving One Care, a Massachusetts demonstration program with capitated reimbursement for individuals ages 18-64 dually eligible for Medicare and Medicaid.

METHODS

Individuals with serious mental illness or significant physical disability designed and implemented "YESHealth: Your Experience, Speak up for better health care." To solicit and communicate with YESHealth members, they mailed postcards announcing YESHealth to potential participants, created a website, sponsored a Facebook group, and staffed telephones in English and Spanish. YESHealth also involved reaching out to numerous disability advocacy organizations, developing and conducting short quarterly surveys about quality concerns they identified, and reporting survey results to YESHealth members and their primary care practitioners.

RESULTS

Over 12 months, YESHealth staff visited 60 community organizations to recruit participants. Recruiting participants was challenging and ultimately required offering monetary compensation. Participants preferred telephone to online communication. Efforts to engage targeted primary care practitioners had very limited success.

CONCLUSIONS

Despite these challenges, YESHealth represents a unique model for consumers' voices to try to affect change in care delivery. A randomized trial has evaluated whether the YESHealth intervention affected care quality for One Care members with disability.

The Central Executive Mediates the Relationship Between Children's Approximate Number System Acuity and Arithmetic Strategy Utilization in Computational Estimation

Studies investigating the relationship between working memory (WM) and approximate number system (ANS) acuity in the area of arithmetic strategy utilization are scarce. The choice/no choice method paradigm was used in the present study to determine whether and how ANS acuity and WM components affected strategy utilization. The results showed that the central executive (CE) mediated the relationship between ANS acuity and strategy utilization. Furthermore, quantile regression analyses revealed that the association between CE and strategy choice was robust from the first to highest quantile. Notably, the relationship between ANS acuity and strategy choice was significant at the median and higher quantiles (i.e., 0.5, 0.75, and 0.85 quantiles), but not significant at lower quantiles (i.e., 0.15 and 0.25 quantiles). These results suggest that domain-general skills play a crucial role in the relationship between children's ANS acuity and mathematical ability. The impact of ANS acuity and CE on strategy choice was dependent on the distribution of the strategy utilization level. These results provide a further understanding of the utilization of cognitive strategies.

"End-of-Life Care? I'm not Going to Worry About That Yet." Health Literacy Gaps and End-of-Life Planning Among Elderly Dialysis Patients

Purpose

Between 2000 and 2012, the incident dialysis population in the United States increased by nearly 60%, most sharply among adults 75 years and older. End-of-life (EOL) conversations among dialysis patients are associated with better patient-centered outcomes and lower use of aggressive interventions in the last month of life. This study examined how health literacy may affect engagement, comprehension, and satisfaction with EOL conversations among elderly dialysis patients.

Design and Methods

Qualitative/descriptive study with semi-structured interviews about health literacy, EOL conversations, and goals of care with 31 elderly dialysis patients at 2 centers in Boston. Themes were interpreted in the context of Nutbeam's health literacy framework.

Results

Despite high mortality risk in this population, only 13% of patients had discussed EOL preferences with physicians, half had discussed EOL with their social network, and 25% of participants explicitly stated that they had never considered EOL preferences. Less than 30% of participants could correctly define terminology commonly used in EOL conversations. Analyses yielded 5 themes: (1) Misunderstanding EOL terminology; (2) Nephrologists reluctant to discuss EOL; (3) Patients conforming to socially constructed roles; (4) Discordant expectations and dialysis experiences; and (5) Reconciling EOL values and future care. Patients had limited understanding of EOL terminology, lacked of opportunities for meaningful EOL discussion with providers and family, resulting in uncertainty about future care.

Implications

Limited health literacy presents a substantial barrier to communication and could lead to older adults committing to an intensive pattern of care without adequate information. Clinicians should consider health literacy when discussing dialysis initiation.

Hospital quality variation matters - A time-trend and cross-section analysis of outcomes in German hospitals from 2006 to 2014

Awareness of care variation and associated differences in outcome quality is important for patients to recognize and leverage the benefits of hospital choice and for policy makers, providers, and suppliers to adapt initiatives to improve hospital quality of care. We examine panel data on outcome quality in German hospitals between 2006 and 2014 for cholecystectomy, pacemaker implantation, hip replacement, percutaneous coronary intervention (PCI), stroke, and acute myocardial infarction (AMI). We use risk-adjusted and unadjusted outcomes based on 16 indicators. Median outcome and outcome variation trends are examined via box plots, simple linear regressions and quintile differences. Outcome trends differ across treatment areas and indicators. We found positive quality trends for hip replacement surgery, stroke and AMI 30-day mortality, and negative quality trends for 90-day stroke and AMI readmissions and PCI inpatient mortality. Variation of risk-adjusted outcomes ranges by a factor of 3-12 between the 2nd and 5th quintile of hospitals, both at the national and regional level. Our results show that simply measuring and reporting hospital outcomes without clear incentives or regulation - "carrots and sticks" - to improve performance and to centralize care in high performing hospitals has not led to broad quality improvements. More substantial efforts must be undertaken to narrow the outcome spread between high- and low-quality hospitals.

Feasibility of an ED-to-Home Intervention to Engage Patients: A Mixed-Methods Investigation

INTRODUCTION

Older, chronically ill patients with limited health literacy are often under-engaged in managing their health and turn to the emergency department (ED) for healthcare needs. We tested the impact of an ED-initiated coaching intervention on patient engagement and follow-up doctor visits in this high-risk population. We also explored patients' care-seeking decisions.

METHODS

We conducted a mixed-methods study including a randomized controlled trial and in-depth interviews in two EDs in northern Florida. Participants were chronically ill older ED patients with limited health literacy and Medicare as a payer source. Patients were assigned to an evidence-based coaching intervention (n= 35) or usual post-ED care (n= 34). Qualitative interviews (n=9) explored patients' reasons for ED use. We assessed average between-group differences in patient engagement over time with the Patient Activation Measure (PAM) tool, using logistic regression and a difference-in-difference approach. Between-group differences in follow-up doctor visits were determined. We analyzed qualitative data using open coding and thematic analysis.

RESULTS

PAM scores fell in both groups after the ED visit but fell significantly more in "usual care" (average decline -4.64) than "intervention" participants (average decline -2.77) (β=1.87, p=0.043). There were no between-group differences in doctor visits. Patients described well-informed reasons for ED visits including onset and severity of symptoms, lack of timely provider access, and immediate and comprehensive ED care.

CONCLUSION

The coaching intervention significantly reduced declines in patient engagement observed after usual post-ED care. Patients reported well-informed reasons for ED use and will likely continue to make ED visits unless strategies, such as ED-initiated coaching, are implemented to help vulnerable patients better manage their health and healthcare.

Designing Visual Aids That Promote Risk Literacy: A Systematic Review of Health Research and Evidence-Based Design Heuristics

Background Effective risk communication is essential for informed decision making. Unfortunately, many people struggle to understand typical risk communications because they lack essential decision-making skills. Objective The aim of this study was to review the literature on the effect of numeracy on risk literacy, decision making, and health outcomes, and to evaluate the benefits of visual aids in risk communication. Method We present a conceptual framework describing the influence of numeracy on risk literacy, decision making, and health outcomes, followed by a systematic review of the benefits of visual aids in risk communication for people with different levels of numeracy and graph literacy. The systematic review covers scientific research published between January 1995 and April 2016, drawn from the following databases: Web of Science, PubMed, PsycINFO, ERIC, Medline, and Google Scholar. Inclusion criteria were investigation of the effect of numeracy and/or graph literacy, and investigation of the effect of visual aids or comparison of their effect with that of numerical information. Thirty-six publications met the criteria, providing data on 27,885 diverse participants from 60 countries. Results Transparent visual aids robustly improved risk understanding in diverse individuals by encouraging thorough deliberation, enhancing cognitive self-assessment, and reducing conceptual biases in memory. Improvements in risk understanding consistently produced beneficial changes in attitudes, behavioral intentions, trust, and healthy behaviors. Visual aids were found to be particularly beneficial for vulnerable and less skilled individuals. Conclusion Well-designed visual aids tend to be highly effective tools for improving informed decision making among diverse decision makers. We identify five categories of practical, evidence-based guidelines for heuristic evaluation and design of effective visual aids.

Exploring the Role of Executive Functioning Capacity in Patient Activation and Health Outcomes Among Medicaid Members With Multiple Comorbidities

Patient activation, the perceived capacity to manage one’s health, is positively associated with better health outcomes and lower costs. Underlying characteristics influencing patient activation are not completely understood leading to gaps in intervention strategies designed to improve patient activation. We suggest that variability in executive functioning influences patient activation and ultimately has an impact on health outcomes. To examine this hypothesis, 440 chronically ill Medicaid enrollees completed measures of executive functioning, patient activation, and health-related quality of life. Mediation analyses revealed that executive functioning: (a) directly affected patient activation and mental health-related quality of life, (b) indirectly affected mental health-related quality of life through patient activation, and (c) was unrelated to physical health-related quality of life. These data indicate that further study of the relationships among neurocognitive processes, patient activation, and health-related quality of life is needed and reinforces previous work demonstrating the association between patient activation and self-reported outcomes.

Online nutrition information for pregnant women: a content analysis

Pregnant women actively seek health information online, including nutrition and food-related topics. However, the accuracy and readability of this information have not been evaluated. The aim of this study was to describe and evaluate pregnancy-related food and nutrition information available online. Four search engines were used to search for pregnancy-related nutrition web pages. Content analysis of web pages was performed. Web pages were assessed against the 2013 Australian Dietary Guidelines to assess accuracy. Flesch-Kincaid (F-K), Simple Measure of Gobbledygook (SMOG), Gunning Fog Index (FOG) and Flesch reading ease (FRE) formulas were used to assess readability. Data was analysed descriptively. Spearman's correlation was used to assess the relationship between web page characteristics. Kruskal-Wallis test was used to check for differences among readability and other web page characteristics. A total of 693 web pages were included. Web page types included commercial (n = 340), not-for-profit (n = 113), blogs (n = 112), government (n = 89), personal (n = 36) and educational (n = 3). The accuracy of online nutrition information varied with 39.7% of web pages containing accurate information, 22.8% containing mixed information and 37.5% containing inaccurate information. The average reading grade of all pages analysed measured by F-K, SMOG and FOG was 11.8. The mean FRE was 51.6, a 'fairly difficult to read' score. Only 0.5% of web pages were written at or below grade 6 according to F-K, SMOG and FOG. The findings suggest that accuracy of pregnancy-related nutrition information is a problem on the internet. Web page readability is generally difficult and means that the information may not be accessible to those who cannot read at a sophisticated level. © 2016 John Wiley & Sons Ltd.

Factors That Matter to Low-Income and Racial/Ethnic Minority Mothers When Choosing a Pediatric Practice: a Mixed Methods Analysis

BACKGROUND

Pediatric practices' scores on healthcare quality measures are increasingly available to the public. However, patients from low-income and racial/ethnic minority populations rarely use these data. We sought to understand potential barriers to using quality data by assessing what factors mattered to women when choosing a pediatric practice.

METHODS

As part of a randomized trial to overcome barriers to using quality data, we recruited women from a prenatal clinic serving an underserved population. Women reported how much 12 factors mattered when they chose a pediatric practice (5-point Likert scale), what other factors mattered to them, and which factors mattered the most. We assessed whether factor importance varied with selected participant characteristics and qualitatively analyzed the "other" factors named.

RESULTS

Participants' (n = 367) median age was 23 years, and they were largely Hispanic (60.4%), white (21.2%), or black (16.9%). Insurance acceptance "mattered a lot" to the highest percentage of women (93.2%), while online information about what other parents think of a practice "mattered a lot" to the fewest (7.4%). Major themes from our qualitative analysis of "other" factors that mattered included physicians' interpersonal skills and pediatrician-specific traits. Factors related to access "mattered the most" to the majority of women.

CONCLUSIONS

Pediatrician characteristics and factors related to access to care may be more important to low-income and racial/ethnic minority women than more commonly reported quality metrics. Aligning both the content and delivery of publicly reported quality data with women's interests may increase use of pediatric quality data.

Shared Decision Making in the Emergency Department Among Patients With Limited Health Literacy: Beyond Slower and Louder

Although studies suggest that patients with limited health literacy and/or low numeracy skills may stand to gain the most from shared decision making (SDM), the impact of these conditions on the effective implementation of SDM in the emergency department (ED) is not well understood. In this article from the proceedings of the 2016 Academic Emergency Medicine Consensus Conference on Shared Decision Making in the Emergency Department we discuss knowledge gaps identified and propose consensus-driven research priorities to help guide future work to improve SDM for this patient population in the ED.

Development and Validation of the Spanish Numeracy Understanding in Medicine Instrument

BACKGROUND

The Spanish-speaking population in the U.S. is large and growing and is known to have lower health literacy than the English-speaking population. Less is known about the health numeracy of this population due to a lack of health numeracy measures in Spanish.

OBJECTIVE

we aimed to develop and validate a short and easy to use measure of health numeracy for Spanish-speaking adults: the Spanish Numeracy Understanding in Medicine Instrument (Spanish-NUMi).

DESIGN

Items were generated based on qualitative studies in English- and Spanish-speaking adults and translated into Spanish using a group translation and consensus process. Candidate items for the Spanish NUMi were selected from an eight-item validated English Short NUMi. Differential Item Functioning (DIF) was conducted to evaluate equivalence between English and Spanish items. Cronbach's alpha was computed as a measure of reliability and a Pearson's correlation was used to evaluate the association between test scores and the Spanish Test of Functional Health Literacy (S-TOFHLA) and education level.

PARTICIPANTS

Two-hundred and thirty-two Spanish-speaking Chicago residents were included in the study.

KEY RESULTS

The study population was diverse in age, gender, and level of education and 70 % reported Mexico as their country of origin. Two items of the English eight-item Short NUMi demonstrated DIF and were dropped. The resulting six-item test had a Cronbach's alpha of 0.72, a range of difficulty using classical test statistics (percent correct: 0.48 to 0.86), and adequate discrimination (item-total score correlation: 0.34-0.49). Scores were positively correlated with print literacy as measured by the S- TOFHLA (r = 0.67; p < 0.001) and varied as predicted across grade level; mean scores for up to eighth grade, ninth through twelfth grade, and some college experience or more, respectively, were 2.48 (SD ± 1.64), 4.15 (SD ± 1.45), and 4.82 (SD ± 0.37).

CONCLUSIONS

The Spanish NUMi is a reliable and valid measure of important numerical concepts used in communicating health information.

Patient activation in Europe: an international comparison of psychometric properties and patients' scores on the short form Patient Activation Measure (PAM-13)

Background

To allow better assessment of patients’ individual competencies for self-management, the Patient Activation Measure (PAM) has been developed in the USA. Because the American studies have shown the PAM to be a valuable tool, several European countries have translated the instrument into their native languages (Danish, Dutch, German, Norwegian). The aim was to compare the psychometric properties in studies from the different countries and establish whether the scores on the PAM vary between the studies.

Methods

Data from the four separate studies were subjected to the same data cleaning procedures and statistical analyses. The psychometric properties of the instruments were established with measures of data quality and scale structure. The mean patient activation score and distribution across four predefined activation levels were described and the differences between the four studies were tested with ANOVA (unadjusted and adjusted) followed by a post-hoc Tukey HSD test and the Pearson chi-squared test respectively.

Results

The total N of the four studies was 5184. The percentage of missing values was low in all datasets, confirming the good quality of the datasets. Factor analyses revealed moderate to strong factor loadings on the first factor in all datasets. Cronbach’s α was high for all version, ranging from .80 (German) to .88 (Dutch). Item-rest correlations varied between .32 and .66, indicating a moderate to strong correlation of the individual items to the sum scale.

Both the mean PAM score and the distribution across activation levels differed between the four datasets. After adjustment of the PAM score, patients in Norway in particular had a higher patient activation level.

Conclusions

The European translations of PAM-13 (into Danish, Dutch, German and Norwegian) resulted in four instruments with good psychometric capabilities for measuring patient activation. The mean PAM score and the distribution across activation levels differed between the four datasets.

Patient Navigators and Parent Use of Quality Data: A Randomized Trial

BACKGROUND

Consumers rarely use publicly reported health care quality data. Despite known barriers to use, few studies have explored the effectiveness of strategies to overcome barriers in vulnerable populations.

METHODS

This randomized controlled trial tested the impact of a patient navigator intervention to increase consumer use of publicly reported quality data. Patients attending an urban prenatal clinic serving a vulnerable population enrolled between May 2013 and January 2015. The intervention consisted of 2 in-person sessions in which women learned about quality performance and viewed scores for local practices on the Massachusetts Health Quality Partners Web site. Women in both the intervention and control arms received a pamphlet about health care quality. Primary study outcomes were mean clinical quality and patient experience scores of the practices women selected (range 1-4 stars).

RESULTS

Nearly all (726/746; 97.3%) women completed the study, 59.7% were Hispanic, and 65.1% had a high school education or less. In both unadjusted and adjusted models, women in the intervention group chose practices with modestly higher mean clinical quality (3.2 vs 3.0 stars; P = .001) and patient experience (3.0 vs 2.9 stars; P = .05) scores. When asked to rate what factors mattered the most in their decision, few cited quality scores.

CONCLUSIONS

An intervention to reduce barriers to using publicly reported health care quality data had a modest effect on patient choice. These findings suggest that factors other than performance on common publicly reported quality metrics have a stronger influence on which pediatric practices women choose.

Activity Theory as a Theoretical Framework for Health Self-Quantification: A Systematic Review of Empirical Studies

BACKGROUND

Self-quantification (SQ) is a way of working in which, by using tracking tools, people aim to collect, manage, and reflect on personal health data to gain a better understanding of their own body, health behavior, and interaction with the world around them. However, health SQ lacks a formal framework for describing the self-quantifiers' activities and their contextual components or constructs to pursue these health related goals. Establishing such framework is important because it is the first step to operationalize health SQ fully. This may in turn help to achieve the aims of health professionals and researchers who seek to make or study changes in the self-quantifiers' health systematically.

OBJECTIVE

The aim of this study was to review studies on health SQ in order to answer the following questions: What are the general features of the work and the particular activities that self-quantifiers perform to achieve their health objectives? What constructs of health SQ have been identified in the scientific literature? How have these studies described such constructs? How would it be possible to model these constructs theoretically to characterize the work of health SQ?

METHODS

A systematic review of peer-reviewed literature was conducted. A total of 26 empirical studies were included. The content of these studies was thematically analyzed using Activity Theory as an organizing framework.

RESULTS

The literature provided varying descriptions of health SQ as data-driven and objective-oriented work mediated by SQ tools. From the literature, we identified two types of SQ work: work on data (ie, data management activities) and work with data (ie, health management activities). Using Activity Theory, these activities could be characterized into 6 constructs: users, tracking tools, health objectives, division of work, community or group setting, and SQ plan and rules. We could not find a reference to any single study that accounted for all these activities and constructs of health SQ activity.

CONCLUSIONS

A Health Self-Quantification Activity Framework is presented, which shows SQ tool use in context, in relation to the goals, plans, and competence of the user. This makes it easier to analyze issues affecting SQ activity, and thereby makes it more feasible to address them. This review makes two significant contributions to research in this field: it explores health SQ work and its constructs thoroughly and it adapts Activity Theory to describe health SQ activity systematically.

Is patients' numeracy related to physical and mental health?

OBJECTIVE

There is compelling evidence showing that health literacy influences health outcomes. However, there is a dearth of research investigating this issue in the vast literature on numeracy-the ability to accurately interpret numerical information about risk, a skill that is only moderately correlated with health literacy. In a cross-sectional study, we investigated whether objective and subjective numeracy is related to objective and subjective health outcomes. Objective (subjective) numeracy is actual (self-reported) numerical competence. Objective outcomes include prevalence of comorbidity and prescribed medications. Subjective outcomes include perceptions of physical and mental health.

METHODS

A convenience sample of 502 male individuals receiving outpatient care at a Veterans Affairs Medical Center reported their demographics and answered a survey measuring objective and subjective numeracy, trust in physicians, satisfaction with role in medical decision making, perceptions of physical and mental health, and risky habits. We computed patients' body mass index (BMI) and their age-adjusted Charlson index-an extensively studied comorbidity index for predicting mortality in clinical research. We retrieved number of prescribed medications from medical records.

RESULTS

Compared with patients who had high objective numeracy, patients with low objective numeracy showed higher prevalence of comorbidities and took more prescribed medications. Compared with patients who had high subjective numeracy, patients with low subjective numeracy had more negative perceptions of their physical and mental health. These conclusions held after controlling for the effect of demographics, risky habits, BMI, trust in physicians, and satisfaction with role in decision making, suggesting that numeracy has a unique, significant contribution to health outcomes beyond the effect of these factors.

CONCLUSIONS

Our research documents for the first time that self-reported numeracy is related to perceptions of health, whereas objective numeracy is related to actual health, laying the groundwork for future research on the effect of numeracy on health outcomes.

Examining Associations between Health Information Seeking Behavior and Adult Education Status in the U.S.: An Analysis of the 2012 PIAAC Data

This paper presents data from the Program for the International Assessment of Adult Competencies with a focus on the interrelationships among health information seeking behavior (HISB), and health status or use of preventive health measures for U.S. adults both with and without a high school diploma. Key results of ordinal and binary logistic regression analyses indicated that, after controlling for demographic factors, (1) adults with a high school diploma use more text-based health information sources while adults without a high school diploma use more oral sources, (2) using the Internet as a source of health information is more strongly related to reporting excellent/very good health status than having a high school diploma, (3) those without a high school diploma who use the Internet report the largest increase in health status over any other health information source, and (4) for those with learning disability or vision problem, a high facility in reading English is an important predictor of whether the Internet is used as a health information source. The Internet appears to play a key role in both enhancing health status and enabling use of preventive measures for those with and without a high school diploma; although, individuals without a high school diploma who use the Internet for health information derive substantial benefit in health status.

The Nursing Home Compare Report Card: Perceptions of Residents and Caregivers Regarding Quality Ratings and Nursing Home Choice

OBJECTIVE

To evaluate the perceived usefulness of publicly reported nursing home quality indicators.

STUDY SETTING

Primary data were collected from October 2013 to August 2014 among a convenience sample of persons (or family member) recently admitted or anticipating admission to a nursing home within 75 miles of the city of Philadelphia.

STUDY DESIGN

Structured interviews were conducted to assess the salience of data on the Medicare Nursing Home Compare website, including star ratings, clinical quality measures, and benchmarking of individual nursing home quality with state and national data.

DATA COLLECTION

Interviews were transcribed verbatim, independently coded by two reviewers, and agreement determined. A thematic analysis of transcripts was undertaken.

PRINCIPAL FINDINGS

Thirty-five interviews were completed. Eighty-three percent (n = 29) were caregivers and 17 percent (n = 6) were residents. Star ratings, clinical quality measures, and benchmarking information were salient to decision making, with preferred formats varying across participants. Participants desired additional information on the source of quality data. Confusion was evident regarding the relationship between domain-specific and overall star quality ratings.

CONCLUSIONS

The Nursing Home Compare website provides salient content and formats for consumers. Increased awareness of this resource and clarity regarding the definition of measures could further support informed decision making regarding nursing home choice.

Cognition, Health Literacy, and Actual and Perceived Medicare Knowledge Among Inner-City Medicare Beneficiaries

Poor Medicare knowledge is associated with worse health outcomes, especially in low-income patients. We examined the association of health literacy and cognition with actual and perceived Medicare knowledge in a sample of inner-city older adults. We conducted a cross-sectional analysis of data on 336 adults ages 65 years and older with Medicare coverage recruited from senior centers and low-income housing facilities in Manhattan, New York. Actual Medicare knowledge was determined by a summary score of 9 true/false questions about the Medicare program and perceived Medicare knowledge with a single item. Validated measures were used to assess health literacy and general cognition. Among respondents, 63.1% had high actual Medicare knowledge, and 36.0% believed that they knew what they needed to know about Medicare. Actual and perceived Medicare knowledge were poorly correlated (r = -.01, p > .05). In multivariable models, low health literacy was significantly associated with actual Medicare knowledge (β = -8.30, SE = 2.71, p < .01) but not perceived Medicare knowledge (β = 0.37, SE = 0.22, p = .09). Individuals with low health literacy were more likely to perceive their Medicare knowledge as adequate when actual Medicare knowledge was low (adjusted odds ratio = 3.30, 95% confidence interval [1.20, 9.05], p < .05). These results show that older adults with low health literacy are more likely to have poor understanding of the Medicare program and yet more likely to believe that their understanding of the program is adequate. This combination of factors may place them at increased risk for poor access to information about the Medicare program and diminish their ability to make fully informed choices.

The association between patient activation and accessing online health information: results from a national survey of US adults

BACKGROUND

There are increasing opportunities for the public to access online health information, but attitudinal barriers to use are less well-known. Patient activation is associated with key health outcomes, but its relationship with using online health information is not known.

OBJECTIVE

We examined the relationship between patient activation and the likelihood of accessing a range of different types of online health information in a nationally representative US sample.

DESIGN

Cross-sectional nationally representative survey.

SETTING AND PARTICIPANTS

Data were from an online (n = 2700) and random digit dial telephone survey (n = 700) of US adults (total n = 3400).

MAIN VARIABLES STUDIED

Respondent characteristics and the Patient Activation Measure.

MAIN OUTCOME MEASURES

Self-reported access of five types of online health information in the past 12 months (online medical records, cost estimation tools, quality comparison tools, health information about a specific condition, preventive health information).

RESULTS

Approximately, one-fifth of the sample had accessed their medical record (21.6%), treatment cost estimation tools (17.3%) and hospital and physician quality comparison tools (21.8%). Nearly half of the sample had accessed information about medical conditions or treatments (48.3%) or preventive health and well-being (45.9%). In multivariable analyses adjusted for participant characteristics, respondents with greater patient activation were more likely to have accessed all types of health information other than cost estimation tools.

DISCUSSION AND CONCLUSIONS

Activated people are more likely to make use of online heath information. Increasing patient activation could improve the public's ability to participate in health care and personal health self-management by encouraging health information seeking.

Optimal health literacy measurement for the clinical setting: A systematic review

OBJECTIVE

To identify the optimal measurement instrument for assessing health literacy in a clinical setting.

METHODS

Seven databases were searched for studies evaluating health literacy instruments used with patients. Standardised systematic review methods were used by two reviewers independently assessing eligibility, extracting data and evaluating study quality. A narrative summary was produced.

RESULTS

The searches identified 626 articles of which 64 were eligible. Forty-three different health literacy instruments were identified. The quality of these instruments, based on their psychometric properties, varied considerably. The majority of health literacy instruments were found to only assess communicative health literacy of which the numeracy element was often not represented. The NVS instrument was found to be the most practical health literacy instrument to use.

CONCLUSION

There is an urgent need to develop and psychometrically test a more encompassing health literacy instrument applicable in clinical settings as well as health promotion in general.

PRACTICE IMPLICATIONS

In the absence of a more comprehensive health literacy instrument, the NVS is a practical instrument to quickly assess for health literacy in a clinical setting.
