Functional Health Literacy In Adults Research Articles

Validation of three health literacy screening questions compared with S-TOFHLA in a low-income diverse English- and Spanish-Speaking population.

Clinicians need a tool to gauge patients' ability to understand health conditions and treatment options. The Short-form Test of Functional Health Literacy in Adults (S-TOFHLA) is the gold standard for this, but its length is prohibitive for use in clinical settings. This study seeks to validate a novel three-item question set for predicting health literacy. This cross-sectional study utilized an in-person questionnaire alongside the S-TOFHLA. The sample included 2027 English- and Spanish-speaking adults (≥18years) recruited from primary care practices serving a low-income eastern Pennsylvania community. Most patients (57.7%) identified as Hispanic. Diagnostic accuracy of each question and aggregated scores were assessed against the validated survey by calculating the area under the receiver operating characteristic (AUROC) curve. Questions in the 'Problems Learning' and 'Help Reading' domains (AUROC 0.66 for each) performed better than the 'Confident Forms' question (AUROC 0.64). Summing all three scores resulted in an even higher AUROC curve (0.71). Cronbach's alpha of the combined items was 0.696. Study results suggest that any of the three questions are viable options for screening health literacy levels of diverse patients in primary care clinical settings. However, they perform better as a summed score than when used individually.

Fatores que influenciam o letramento em saúde em pacientes com doença arterial coronariana

Objective: to investigate the factors that exert an influence on health literacy in patients with coronary artery disease. Methods: a crosssectional study, including 122 patients with coronary diseases (60.7% male; 62.07 ± 8.8 years old). Health literacy and specific knowledge about the disease were evaluated through interviews with the participants by means of the Short Test of Functional Health Literacy in Adults and the Short version of the coronary artery disease education questionnaire. The data were described by means of central tendency measures and frequencies. The factors that exert an influence on health literacy were determined by means of a linear regression model. The significance level adopted was 5%. The study was approved by the Research Ethics Committee. Results: age and arterial hypertension presented an inverse and significant relationship with health literacy. On the other hand, higher schooling levels and having a job were associated with better scores in the health literacy instrument. Specific knowledge about the disease did not exert any influence on health literacy. The variables included in the regression model explained 55.3% of inadequate literacy. Conclusion: this study, knowledge about the disease exerts no influence on health literacy: however, the professionals should consider the sociodemographic and clinical factors to plan the interventions.

55 Health literacy mediates racial differences in cognitive functioning among people with and without HIV

Objective:Health disparities among African Americans (AAs) in the United States are evident, especially among older adults and people living with HIV (PLWH). These health disparities include worse cognitive functioning among AAs than White counterparts. Though disparities in health literacy among AAs impact health outcomes across clinical populations, less is known on the mechanistic role health literacy may play in explaining racial differences in cognitive functioning among older PLWH. The current study investigated the association between health literacy and global cognitive functioning among middle-aged and older AA and White adults with and without HIV in the Deep South.Participants and Methods:Two hundred and seventy-three people (170 PLWH: 146 AA, 24 White; 103 HIV-negative: 67 AA, 36 White) were enrolled in an observational study and completed measures of sociodemographic characteristics, as well as the reading subtest of the Wide Range Achievement Test-3rd Edition to assess verbal IQ. A composite score of socioeconomic status (SES) was created using total years of education and annual household income. Neurocognitive functioning was assessed using a comprehensive cognitive battery (i.e., verbal, attention/working memory, executive function, learning, recall, speed of processing, and motor), from which a sample-based global Z-score composite was created. Health literacy was measured using a sample-based composite Z-score derived from the Rapid Estimate of Adult Literacy in Medicine, Test of Functional Health Literacy in Adults Reading Comprehension, Newest Vital Sign, and Expanded Numeracy Scale. First, multivariable linear regression analyses were performed within both PLWH and HIV-negative samples examining the association between race, SES, verbal IQ, and health literacy with cognitive functioning. These results informed two bootstrap confidence interval mediation analyses to determine whether health literacy mediated the association between race and global cognitive functioning.Results:In both PLWH and HIV-negative individuals, linear regressions showed that Whites had better global cognitive functioning, health literacy, and verbal IQ than AAs. Linear regressions showed that health literacy had an independent association with cognitive function when accounting for verbal IQ and SES. Mediations showed that health literacy significantly mediated the association between race and global cognitive functioning in both samples, independent of verbal IQ (PLWH: b = .07, 95% CI [0.0096, 0.2149]; HIV-negative: b = .15, 95% CI [0.0518, 0.2877]), indicating that Whites were expected to obtain higher global cognitive Z-scores than AAs in both PLWH and HIV-negative samples, through the mediating effect of better health literacy.Conclusions:Health literacy significantly mediated the association between race and global cognitive functioning among middle-aged and older adults with and without HIV, underscoring the importance of health literacy in explaining racial disparities in cognitive outcomes among AAs in the Deep South. Findings have implications for guiding clinicians and healthcare providers in developing interventions that promote health literacy in these underserved populations, which may have downstream impacts on cognitive functioning. Future work is needed to examine mechanisms whereby health literacy impacts neurocognition among AA PLWH.

The Relationship Between Signature Time and Functional Health Literacy: Results from a Prospective Study of an Urban Low-Income Population Receiving Long-Term Anticoagulation.

Low health literacy (HL) is consistently associated with worse health outcomes. Routine clinical screening with available instruments is impractical because of added time and effort. Prior findings suggested that signature time may be a reliable alternative measure of HL among general medicine patients. Our aim was to assess the screening performance of signature time and explore optimal thresholds for identifying patients with limited HL in a chronically anticoagulated population. English-speaking patients receiving long-term anticoagulation therapy were recruited. HL was assessed using the Short Test of Functional Health Literacy in Adults (STOFHLA). Signature time was measured using a stopwatch. Logistic regression models and receiver-operating characteristic (ROC) curves were used to evaluate the association and accuracy of signature time compared to HL, respectively. Of 139 enrolled patients, mean age was 60.1 years, 70.5% were African-American, 48.9% reported < $25,000 income, and 27.3% had marginal or inadequate HL. Overall, median time to sign was 6.1 s. Signature time was longest with inadequate HL (median 9.5 s) compared to adequate HL (5.7 s; p < 0.01). Longer signature time was significantly associated with lower HL after adjusting for age and education (aOR 0.77, 95% CI: 0.68-0.88, p < 0.01). Signature time demonstrated high accuracy (area under the curve [AUC] > 0.8) in identifying HL levels. Thresholds of 5.1 s and 9.0 s showed appropriate screening performance in distinguishing patients with adequate vs. marginal and marginal vs. inadequate HL, respectively. Signature time demonstrated strong screening performance and may offer a quick and practical approach to assessing HL among patients receiving long-term anticoagulation management.

#3311 INDEPENDENT PREDICTORS FOR COMMUNITY-ACQUIRED ACUTE KIDNEY INJURY: A PROSPECTIVE COHORT STUDY

Abstract Background and Aims Acute Kidney Injury (AKI) is a syndrome characterized by an abrupt drop in glomerular filtration and/or a decrease in urinary output. The awakening to a different kind of AKI that also occurs outside the hospital named community-acquired AKI (CA-AKI) occurred in 1991, however, few data have been published about its epidemiology, risk factors and outcome, especially in low-income countries. The recognition of risk factors for CA-AKI and development of symptom-based risk tool that aims to predict the risk of AKI might be able to avoid delays in its recognizing, improve the timely diagnosis and patient outcomes in this frequent syndrome. We aimed to assess CA-AKI incidence, characteristics and independent risk factors associated with CA-AKI; to evaluate the discriminatory capacity of a clinical score tool to AKI prediction to predict CA-AKI in our sample. Method We conducted a prospective observational study of general medical admissions to a tertiary hospital in Campinas (São Paulo) between 10th January 2019 and 16th September 2021; we included patients ≥ 14 years, medical suspicion of infection (or confirmed) and /or presence of at least one of the signs or symptoms on admission: fever, dyspnea, decrease in urine output, edema, hypotension, hemodynamic shock, jaundice, petechiae, ecchymosis or decreased level of consciousness. We excluded patients with stage 5 chronic kidney disease at baseline and pre-existing renal replacement therapy (undergoing dialysis and renal transplantation), and also patients with COVID diagnosis. All patients included were assessed utilizing a symptom-based risk score to predict the development of severe AKI, the need for dialysis and mortality. Patients were subjected to complete history taking, socioeconomic and education data were collected. Healthy literacy was assessed using the test of functional health literacy in adults – short version (S- TOFHLA). Predictors of CA-AKI risk were assessed using multivariate logistic regression analysis. Patients were followed up until discharged hospital. The study outcomes were development of CA-AKI, hospital mortality, dialytic need. Results We enrolled 261 patients. CA-AKI was diagnosed in 65 (25%) patients. The CA-AKI patients were older [59 (51-66) vs. 54 (38-65) years, p = 0,02], had higher basal serum creatinine [0,7 (0,5–0,9) vs. 0,6 (0,5-0,8) mg/dL; p = 0,01], lower baseline estimated glomerular filtration rate (eGFR) [103 (88–113) vs. 109 (97–121) mL/min/1,73 m2; p = 0,01] and lower eGFR on admission [64 (44 – 81) vs. 104 (82 – 116) mL/min/1,73 m2; p = 0,0001]. Liver and heart disease were most common comorbidities in the group CA-AKI [10 (16%) vs. 14 (7%) patients, p = 0.04 and 21 (33%) vs. 39 (20%), p = 0,03, respectively]. The risk score did not show significant accuracy to predicting CA-AKI, however, logistic regression showed that scores ≥7 points (OR 95% CI 1.282, 6.133 p = 0.010) followed by age (OR 95% CI 1.007, 1.044 p = 0.008] and liver disease (95% CI 1.063, 6.379 p = 0,036) were independent factors associated with increased risk for CA-AKI in our population. A higher percentage of patients in our sample declared household income &amp;lt; $ 719.73 (month) and the CA-AKI group maintained the same distribution. Only 41 (16%) patients were able to perform the S-TOFHLA and 18 (44%) were considered inadequate or insufficient health literacy. For hospitalized patients, the mean hospital stay in CA-AKI group was longer [8 (4-18) vs. 4 (2-11) days p = 0,001] than without CA-AKI. Overall mortality rate during the follow up was 5% (13 patients), need dialysis 1% (2 patients) and were not statistically significant between the groups. Conclusion Healthy literacy, education, and social class did not show association with CA-AKI; dialysis needed and mortality were not different between the groups CA-AKI or without CA-AKI. Covariates and factors associated with risk for CA-AKI were age, liver disease and scores ≥7 points. The main limitation of our study was not feasible to screen all the patients due to the high numbers seen daily.

Examining health literacy and self-efficacy levels and their association with preventive behaviors of urinary tract infection in Iranian pregnant women: across sectional study

ObjectiveUrinary tract infection (UTI) is assumed to be associated with the risk of fetal and maternal mortality and morbidity during pregnancy. The potential effect of health literacy and self-efficacy on UTI preventive behaviors among pregnant women has not yet been fully studied. Our objectives were to determine the level of health literacy, self-efficacy, and UTI prevention behaviors in pregnant women, and whether health literacy and self-efficacy are associated with UTI prevention behaviors in pregnant women.DesignA cross-sectional study was conducted, from November 2020 to December 2020, through a multi-stage sampling design on 235 pregnant women aged between 18 and 42 years in Mashhad, Iran. Data were collected through valid and reliable questionnaires including the Test of Functional Health Literacy in Adults (TOFHLA), General Self-Efficacy Questionnaire (GSE), and research made-preventive behaviors recommendations for UTI disease.ResultsThe level of UTI prevention behaviors scores is moderate (71.39 ± 8.58) among women during their pregnancy. Insufficient health literacy and self-efficacy were observed in 53.6% and 59.3% of participants, respectively. The regression model highlighted that 21.20% of the total variance of UTI preventive behaviors was predicted by sociodemographic characteristics, while 40.81% of the variance of UTI preventive behaviors was predicted by health literacy and self-efficacy.ConclusionIt has been observed that health literacy and self-efficacy are main determinants to improve UTI preventive behaviors. Focusing on an intervention based on health literacy skills may be a practical strategy to promote a healthy lifestyle in this population.

Validation of the Arabic Version of the Health Literacy (HLS-Q12) Questionnaire in chronically ill patients.

Health literacy (HL) is an essential component of public health. Few tools are used to measure HL in Arabic-speaking countries, essentially the Short Test of Functional Health Literacy in Adults and the Single Item Literacy Screener. The new 12-item version of the European Health Literacy Survey Questionnaire (HLS-Q12), has not been validated in the Arabic language. This study aimed to translate the English version of HLS-Q12 into Arabic, test its structure and explain any variance in HLS-Q12 scores, allowing its use in Arabic-speaking healthcare contexts. A forward-backward translation was adopted. Reliability was assessed using Cronbach's α. Confirmatory factor analysis (CFA) and Rasch Model evaluated the model fit of the Arabic version of HLS-12. The effects of different patient-related variables on HLS-Q12 scores were tested using linear regression. A total of 389 patients visiting the site hospital outpatient clinics participated in the study. HLS-Q12 mean ± SD score was 35.8 ± 5.0, 50.9% of the participants showed an intermediate HL score. Good reliability (α = 0.832) was observed. CFA confirmed the scale unidimensionality. Rasch analysis indicated HLS-Q12 items to be within the fit acceptable thresholds except for Item 12. The only item that displayed unordered response categories was Item 4. Most of the items were considered relatively easy by respondents. Linear regression revealed age, education, healthcare-related education and income to have effects significantly different from zero on HLS-Q12 score. Interventions targeting the most health-disparate groups of individuals with characteristics contributing to lower HL, are needed.

Abstract P642: Assessment of Health Literacy in Colombia: A First Step for a Cardiovascular Education Program for the Community

Introduction: Adequate health literacy enables patients and caregivers to make appropriate decisions and achieve better health outcomes. However, much information about health literacy comes from developed and English-speaking countries. There is very little information about health literacy levels in countries such as Colombia and these data, therefore, cannot be used as an input in the development of cardiovascular education programs for the community. Our objective was to optimize and adapt the Spanish validation of the short version of the Test of Functional Health Literacy in adults (s-TOFHLA) to the context of the Colombian health system. This test was chosen because its multiple questions and sections can guide the skills that should be emphasized in a health education course for patients and caregivers (i.e. navigation in the health care system, interpretation of medical instructions, understanding of doses and forms of drug dispensing). This test consists of two parts: numerical and reading comprehension (Readings A and B). The TOFHLA is graded using a score between 1 and 100 points, which classifies the participant into categories of adequate, marginal or inadequate health literacy. Methods: The validation process was carried out in the following steps 1) cultural and language adaptation, 2) expert consensus (n=7), 3) a cognitive survey (n=10), 4) piloting (n=40), and 5) application in the community (n=148). The study was conducted in 6 cities, from 5 departments (equivalent to an state) in Colombia. Results: In the piloting (n=40) Cronbach's α was 0.76 for numerical comprehension, 0.58 for reading A, and 0.95 for reading B. In the broader sample (n=148) the Cronbach's α for numerical comprehension, reading A and reading B was 0.84, 0.89, and 0.95, respectively. Most of the sample had an adequate level of literacy (77.1%), however, the percentages in the marginal (6%) and inadequate (16.7%) categories can still be considered high. Health literacy levels are lower in people with the lowest level of schooling and socioeconomic strata. In addition, there seem to be differences between urban and rural populations. No differences have been observed according to the sex of the participants. Conclusions: It is critical to assess health literacy with instruments that have been adequately validated and adapted to the conditions of each health system. This process requires the participation of health and language experts. The piloting and cognitive surveys provide a good idea of how communities interpret psychometric tests. Our results confirm differences in health literacy among populations with different levels of income and schooling. Health literacy assessment can guide the instructional design of community-directed health education programs.

Health Literacy predicts incident foot ulcers after 4 years – the SHELLED cohort study

Aims/hypothesisTo determine whether health literacy is associated with an index diabetes-related foot ulcer (DFU).MethodsThe SHELLED Study is a 4-year prospective study of people with diabetes aged over 40 with no history of DFU. The primary outcome was development of a first foot ulcer. Health Literacy was measured using the short form Test of Functional Health Literacy in Adults (s-TOFHLA) and nine domains of the Health Literacy Questionnaire (HLQ).ResultsOf 222 participants, 191 (86.0%) completed the study, of whom 13 (5.9%) developed an incident ulcer. In multivariable models, every unit increase in S-TOFHLA was associated with a reduced odds of foot ulcer development by 6% (OR 0.94, 95% CI 0.88 to 0.99). Better scores on two HLQ domains reduced the odds of foot ulcer (actively managing my health (OR 0.23, 95% CI 0.08 to 0.65) and understanding health information well enough to know what to do (OR 0.39, 95% CI 0.19 to 0.78). This was independent of baseline risk for foot disease.Conclusions/interpretationThese data provide novel evidence that health literacy is an important clinical risk factor for index foot ulceration. This is an area of potential focus for research and development of educational programs or policy aimed at reducing development of incident foot ulceration.

Health literacy and health behaviors of Guinean university students residing in Brazil.

To evaluate the health literacy and health behaviors of Guinean university students residing in Brazil. A cross-sectional, analytical study conducted with 51 Guinean university students residing in Brazil. A health behavior questionnaire and the Test of Functional Health Literacy in Adults - Short version were applied. Spearman correlation coefficient, U of Mann-Whitney and Kruskal-Wallis were calculated. Health literacy was adequate (median=79; IQR=24). Reading comprehension (median=70; IQR=16) of health information was better than numerical comprehension (median=14; IQR=14). Better health literacy performance was found in those with daily screen time of 3 to 5 hours (p=0.004) and who consumed fatty meat (p=0.002). Adequate health literacy of Guinean university students was associated with mostly healthy behaviors, except for screen time and consumption of fatty meat.

Evaluation of Health Literacy Levels and Associated Factors Among Patients with Acute Coronary Syndrome and Heart Failure in Qatar.

To determine the prevalence of inadequate health literacy and its associated risk factors among patients with acute coronary syndrome (ACS) and/or heart failure (HF) in Qatar. This cross-sectional observational study was conducted among patients with ACS and/or HF attending the national Heart Hospital in Qatar. Health literacy was assessed using the abbreviated version of the Test of Functional Health Literacy in Adults (S-TOFHLA) and the Three-item Brief Health Literacy Screen (3-item BHLS). Three hundred patients with ACS and/or HF, majority male (88%) and non-Qatari (94%), participated in the study. The median (IQR) age of the participants was 55 (11) years. The prevalence of inadequate to marginal health literacy ranged between 36% and 54%. There were statistically significant differences in health literacy level between patients based on their marital status (p=0.010), education (p≤0.001), ability to speak any of Arabic, English, Hindi, Urdu, Malayalam, or other languages (p-values ≤0.001 to 0.035), country of origin (p≤0.001), occupation (p≤0.001), and receiving information from a pharmacist (p=0.008), a physiotherapist (p≤0.001), or a nurse (p=0.004). Inadequate health literacy is common among patients with ACS and/or HF. This study suggests a need for developing strategies to assist healthcare professionals in improving health literacy skills among patients with ACS and HF. A combination of interventions may be needed to improve patients' understanding of their disease and medications, and ultimately overall health outcomes.

Insight into global research on health literacy and heart diseases: A bibliometric analysis.

Health literacy (HL) has shown its important role on reducing the burden of heart diseases. However, no study has provided a comprehensive worldwide view of the data regarding HL and heart diseases. The study aimed to provide insight into: (1) the intellectual structure, (2) research trends, and (3) research gaps on HL and heart diseases; and (4) to explore HL scales commonly utilized in heart studies. Studies related to HL and heart diseases were retrieved from Web of Science, Scopus, and PubMed. All publications published between 2000 and 2021 were included after conducting keyword searches on "heart diseases" in general or on specific types of heart diseases (e.g., "heart failure") and "health literacy". Bibliometric analyses were carried out using the Bibliometrix R package and VOSviewer 1.6.14. A total of 388 original research articles and reviews on HL and heart diseases were included in our study. The studies were primarily conducted in the United States and developed countries. A total of 337 studies (86.9%) focused on heart failure (200 studies, 51.5%) and ischemic heart diseases (137 studies, 35.3%). Sixty-two studies (16.0%) focused on other heart diseases (e.g., valvular diseases and rheumatic heart diseases). The number of interventional studies was limited (52 studies, 13.4%) and fluctuated from 2000 to 2021. The most common questionnaires measuring health literacy among patients with heart diseases were the Test of Functional Health Literacy in Adults (TOFHLA), Short Test of Functional Health Literacy in Adults (STOFHLA), and Brief Health Literacy Screen (BHLS). Use of the eHealth Literacy Scale (eHEALS) has become the latest trend among patients with heart diseases. Health literacy and heart diseases were most often studied in the United States and developed countries. Several HL tools were used; eHEALS has been lately used in this field. These findings suggest the need to conduct more empirical studies on HL and heart diseases in different settings (e.g., developing or poor countries) and with different types of heart diseases (e.g., valvular and rheumatic disorders). Additionally, it is necessary to develop heart disease-specified HL scales for research and practice.

Cognitive impairment and low health literacy are associated with poor health outcomes in patients with heart failure

Abstract Background Cognitive impairment and low health literacy are prevalent in patients with heart failure (HF). Low health literacy is associated with poor health outcomes, such as frequent re-hospitalizations and increased mortality. Little is known about the relationships among cognitive impairment, health literacy, and health outcomes (HF rehospitalization and cardiac death). Objective To explore the associations among cognitive impairment, health literacy, and cardiac event-free survival in patients with HF. Methods This was a longitudinal study of 614 rural patients with HF (male 59%, age 66±13 NYHA class III/IV: 35%). Cognitive function was measured using the Mini-Cog test. Health literacy was measured by the Short Test of Functional Health Literacy in Adults. HF hospitalizations and cardiac mortality were followed at least 2 years and obtained by patient interview, medical record review, and death certificate review. Chi-squares, t-tests, ANOVA, Kaplan-Meier with log rank tests, logistic and Cox regressions were used for data analysis. Results Two hundred and seven patients (34%) had cognitive impairment. Compared to those without cognitive impairment, patients with cognitive impairment were 2.77 times more likely to have low health literacy (P&amp;lt;0.001). Patients were divided into 4 groups based on cognitive impairment or not and adequate/low health literacy: (1) No cognitive impairment with adequate health literacy; (2) cognitive impairment with adequate health literacy; (3) no cognitive impairment with low health literacy; and (4) cognitive impairment with low health literacy. Both cognitive impairment and health literacy independently predicted cardiac event-free survival. Cardiac event-free survival was worst in those with both cognitive impairment and low health literacy compared to patients in any of the other three groups. Patients with cognitive impairment and low health literacy had 3.5 times higher risk of a cardiac event compared to those without cognitive impairment or low health literacy (P&amp;lt;0.001, Figure). Age, income, angiotensin converting enzyme inhibitor use, beta-blocker use, New York Heart Association functional class, left ventricular ejection fraction, BNP level were significantly different among the four cognitive and literacy groups. Conclusion Patients with cognitive impairment with low health literacy were at high risk of experiencing a cardiac event. Interventions need to be developed to target high risk patients with cognitive impairment and low health literacy, such as older, low-income patients, to alleviate poor outcomes in patients with HF.

Validation of the Short-Test of Functional Health Literacy in Adults for the Samoan Population.

Background:Health literacy encompasses various levels of communication for an individual, provider, and an organization. Validated and reliable tools have been developed to assess health literacy; however, there is a paucity of tools available to assess health literacy in native languages for indigenous and racial/ethnic minority populations.Objective:This article shares the process taken to translate and evaluate validation and reliability of the Short Test of Functional Health Literacy in Adults for use with the Samoan population.Methods:Respondent-driven sampling was used to collect data from 1,543 adults age 45 years and older in American Samoa. A confirmatory factor analysis using a two-factor model for validation was conducted.Key Results:The validation results indicated a “good fit” in multiple indices and Cronbach's alpha indicated high internal consistency in both the English and Samoan languages.Conclusions:Developing culturally validated and reliable health literacy assessment tools is important to help health care professionals decrease health disparities and address inadequate health literacy in all cultures. [HLRP: Health Literacy Research and Practice. 2022;6(4):e247–e256.]Plain Language Summary:The INSPIRE project studied the Short Test of Functional Health Literacy in Adults (STOFHLA) tested on the American Samoan population age 50 years and older. The results would show if the STOFHLA is a valid tool to measure functional health literacy in American Samoa adults.

Tools to Measure Health Literacy among Adult Hispanic Populations with Type 2 Diabetes Mellitus: A Review of the Literature.

Health literacy (HL) is associated with short- and long-term health outcomes, and this is particularly relevant in Hispanics, who are disproportionally affected by lower HL. Hispanics have become the largest minority population in the United States. Also, Hispanics experience higher burdens of chronic diseases such as type 2 diabetes mellitus (T2DM) than non-Hispanic whites. Thus, effectively choosing culturally appropriate validated instruments that measure a marker found in health assessments should be a serious consideration. Using a systemized approach, we identified and reviewed 33 publications and found eight different HL and numeracy (separate or combined) instruments. We assessed the study designs and instrument structures to determine how HL was measured across these studies. We categorized the results into direct and indirect measurements of HL. The Test of Functional Health Literacy in Adults (TOFHLA) family of HL instruments was favored for direct measures of HL, while the Brief Health Literacy Screen (BHLS) instrument was favored for indirect measures. Despite identified trends in instruments used, more comprehensive measurement tools have been developed but not validated in Hispanic populations. In conclusion, further validation of more comprehensive HL instruments in adult Hispanic populations with T2DM could better assess HL levels and improve health promotion efforts.

Impact of low health literacy on patients’ health outcomes: a multicenter cohort study

BackgroundThis study aims to assess the health literacy of medical patients admitted to hospitals and examine its correlation with patients’ emergency department visits, hospital readmissions, and durations of hospital stay.MethodsThis prospective cohort study recruited patients admitted to the general internal medicine units at the two urban tertiary care hospitals. Health literacy was measured using the full-length Test of Functional Health Literacy in Adults. Logistic regression analyses were performed to examine the correlation between health literacy and the desired outcomes. The primary outcome of interest of this study was to determine the correlation between health literacy and emergency department revisit within 90 days of discharge. The secondary outcomes of interest were to assess the correlation between health literacy and length of stay and hospital readmission within 90 days of discharge.ResultsWe found that 50% had adequate health literacy, 32% had inadequate, and 18% of patients had marginal health literacy. Patients with inadequate health literacy were more likely to revisit the emergency department as compared to patients with adequate health literacy (odds ratio: 3.0; 95% Confidence Interval: 1.3–6.9, p = 0.01). In patients with inadequate health literacy, the mean predicted probability of emergency department revisits was 0.22 ± 0.11 if their education level was some high school or less and 0.57 ± 0.18 if they had completed college. No significant correlation was noted between health literacy and duration of hospital stay or readmission.ConclusionsOnly half of the patients admitted to the general internal medicine unit had adequate health literacy. Patients with low health literacy, but high education, had a higher probability of emergency department revisits.

Community health literacy outcome measurement practices: A scoping review of recent interventions.

IntroductionEvidence suggests that, while a preference for functional Health Literacy (HL) outcome measurement exists, researchers are converging towards more all‐encompassing instruments. While this claim is present in the HL field, minimal research has comprehensively explored the state of community HL measurement practices at the direct and proxy level. The almost exclusive focus on direct, as opposed to proxy, community HL measurement indicates a review of progress is needed.ObjectiveTo identify HL outcome measurement practices for community HL interventions at the direct and proxy level of measurement.Search StrategyMedline, PsycINFO, Web of Science, ERIC, Embase, Scopus, CINAHL, ProQuest Dissertations and Theses, Google Scholar and targeted websites were searched.Inclusion CriteriaStudies were sampled from the general population, included HL as an outcome of interest, involved an intervention aiming to improve HL, were English‐text publications and were published ≥2010.Data Extraction and SynthesisStudy author(s) and publication years, sample characteristics, intervention profiles and direct and proxy instrument and outcome measurement information were extracted. Full‐text review retrieved 25 eligible studies.Main ResultsIn total, 21 unique direct and 38 unique proxy instruments were extracted. The majority of interventions assessed functional compared to communicative, critical, and other HL domains, with objective instruments more frequently used than subjective or combined objective‐subjective types, though more unique subjective HL instruments were extracted overall. The Test of Functional HL in Adults was the most popular instrument, and perceived health, knowledge, behaviors and health intentions were the most frequent proxy outcome measures, with only the Healthy Lifestyle Behavior Scale‐II and Patient Activation Measure used across multiple interventions.Discussion and ConclusionsDirect HL outcome practices endured a unidimensional profile, despite previous suggestions of a convergence towards holistic instruments. This review provides the first overview of proxy HL measurement across community HL interventions, identifying substantial variation in proxy outcome practices.Patient or Public ContributionA University‐based senior librarian contributed to the development of the search strategy, and reviewed iterations of the strategy until refinement was complete.

Psychometric Evaluation of Three Translated Measures of Functional Health Literacy among Jordanians.

Assessment of functional health literacy (FHL) is not integrated into clinical settings in Jordan possibly because relevant psychometric studies are lacking. The aim of this secondary analysis of data on family caregivers (N = 115) was to evaluate the internal consistency reliability and construct validity of three measures of FHL among Jordanians: the Short Test of Functional Health Literacy in Adults (S-TOFHLA), the Rapid Estimate of Adult Literacy in Medicine-Revised (REALM-R), and the Single Item Literacy Screener (SILS). Cronbach's alpha was excellent for the S-TOFHLA (.92), but suboptimal for the REALM-R (.67). In bivariate analysis, FHL measured by the S-TOFHLA and the REALM-R, but not the SILS, was positively associated with educational attainment (p < .05) and negatively related to self-reported anxiety (p < .05). Among Jordanians, psychometric rigor was fully demonstrated for the S-TOFHLA and partially for the REALM-R, but not for the SILS.

Prospective associations of health literacy with clinical outcomes in adults with CKD: findings from the CRIC study.

Limited health literacy is associated with significant morbidity and mortality in the general population but the relation of health literacy with long-term clinical outcomes among adults with chronic kidney disease (CKD) is less clear. Prospective data from the Chronic Renal Insufficiency Cohort (CRIC) Study (n=3715) were used. Health literacy was assessed with the Short Test of Functional Health Literacy in Adults (dichotomized as limited/adequate). Cox proportional hazards models were used to separately examine the relations of health literacy with CKD progression, cardiovascular event (any of the following: myocardial infarction, congestive heart failure, stroke or peripheral artery disease), and all-cause, cardiovascular and non-cardiovascular mortality. Poisson regression was used to assess the health literacy-hospitalization association. Models were sequentially adjusted: Model 1 adjusted for potential confounders (sociodemographic factors), while Model 2 additionally adjusted for potential mediators (clinical and lifestyle factors) of the associations of interest. In confounder-adjusted models, participants with limited (vs adequate) health literacy [555 (15%)] had an increased risk of CKD progression [hazard ratio (HR) 1.34; 95% confidence interval (CI) 1.06-1.71], cardiovascular event (HR 1.67; 95% CI 1.39-2.00), hospitalization (rate ratio 1.33; 95% CI 1.26-1.40), and all-cause (HR 1.54; 95% CI 1.27-1.86), cardiovascular (HR 2.39; 95% CI 1.69-3.38) and non-cardiovascular (HR 1.27; 95% CI 1.01-1.60) mortality. Additional adjustments for potential mediators (Model 2) showed similar results except that the relations of health literacy with CKD progression and non-cardiovascular mortality were no longer statistically significant. In the CRIC Study, adults with limited (vs adequate) health literacy had a higher risk for CKD progression, cardiovascular event, hospitalization and mortality-regardless of adjustment for potential confounders.
