Health Literacy and Outcomes of a Community-Based Self-Help Intervention: A Case of Korean Americans With Type 2 Diabetes

Health Literacy among Korean American Immigrant Women in the USA: Role of Social Support

Health literacy is associated with health behaviors and outcomes. Using Andersen's Behavioral Model of Health Services Use, this study examined the role of limited English proficiency (LEP) and social support for the health literacy of Korean American immigrant women, one of the most affected groups by LEP. Researchers surveyed 232 Korean American immigrant women in a metro area in a Southeastern state, U.S. Health literacy was measured by the CDC Behavioral Risk Factor Surveillance System Questionnaire and the California Health Interview Survey. Participants with better English proficiency and larger social support had higher health literacy. LEP and social support interaction was significantly associated with health literacy, illustrating social support as a buffer that mitigates the negative impact of LEP on health literacy. Community programs that enhance social support through community health advocates or peer educators may increase health literacy and reduce health disparities among Korean American immigrant women with LEP.

Demographic and Socioeconomic Patient Data Are Rarely Included in Randomized Controlled Trials for Femoral Acetabular Impingement and Hip Arthroscopy: A Systematic Review

Purpose

To determine the rate of reporting for sociodemographic variables in randomized controlled trials (RCTs) investigating femoral acetabular impingement (FAI) and hip arthroscopy.

Methods

PubMed, Scopus, and Web of Science were queried for articles relating to FAI and hip arthroscopy. Articles included in final analysis were RCTs investigating operative management of FAI. Included RCTs were analyzed for reporting of age and sex or gender as well as the following sociodemographic variables: race, ethnicity, insurance status, income, housing status, work status, and education level in the results section or any section of the paper. Data was analyzed using χ2 and Fisher exact tests with significance defined as P < .05.

Results

Forty-eight RCTs were identified from 2011 to 2023. Age was reported in 48 of 48 (100%) of included papers; sex or gender was reported in 47 of 48 (97.9%). Reporting of sociodemographic variables in any section respectively was: race (7/48, 14.6%), ethnicity (4/48, 8.33%), insurance status (0/48, 0%), income (1/48, 2.08%), housing status (0/48, 0%), work status (3/48, 6.25%), and education (2/48, 4.17%). There was no significant difference for reporting demographic variables with respect to journal or year of publication (P = .666 and P = .761, respectively). Sociodemographic variables (9/48) were reported significantly less frequently than age and sex or gender (48/48) (P < .001).

Conclusions

This study found that sociodemographic variables in FAI and hip arthroscopy RCTs are reported with much lower frequency than age and sex or gender. These findings may demonstrate the need to include patient sociodemographic data in RCTs so that their results can be better generalized and applied to the appropriate patient population.

Level of Evidence

Level II, systematic review of level I and II evidence.

The Role of Artificial Intelligence in Endocrine Management: Assessing ChatGPT's Responses to Prolactinoma Queries

This research investigates the utility of Chat Generative Pre-trained Transformer (ChatGPT) in addressing patient inquiries related to hyperprolactinemia and prolactinoma. A set of 46 commonly asked questions from patients with prolactinoma were presented to ChatGPT and responses were evaluated for accuracy with a 6-point Likert scale (1: completely inaccurate to 6: completely accurate) and adequacy with a 5-point Likert scale (1: completely inadequate to 5: completely adequate). Two independent endocrinologists assessed the responses, based on international guidelines. Questions were categorized into groups including general information, diagnostic process, treatment process, follow-up, and pregnancy period. The median accuracy score was 6.0 (IQR, 5.4-6.0), and the adequacy score was 4.5 (IQR, 3.5-5.0). The lowest accuracy and adequacy score assigned by both evaluators was two. Significant agreement was observed between the evaluators, demonstrated by a weighted κ of 0.68 (p = 0.08) for accuracy and a κ of 0.66 (p = 0.04) for adequacy. The Kruskal-Wallis tests revealed statistically significant differences among the groups for accuracy (p = 0.005) and adequacy (p = 0.023). The pregnancy period group had the lowest accuracy score and both pregnancy period and follow-up groups had the lowest adequacy score. In conclusion, ChatGPT demonstrated commendable responses in addressing prolactinoma queries; however, certain limitations were observed, particularly in providing accurate information related to the pregnancy period, emphasizing the need for refining its capabilities in medical contexts.

Effect of online infographics for enhancing health literacy among patients with type 2 diabetes in primary care unit during the COVID-19 pandemic: a randomized controlled trial

BACKGROUND

Health literacy (HL) in patients with type 2 diabetes mellitus (DM) can help control disease and prevent complications. However, most patients with type 2 DM have inadequate HL; therefore, their HL must be further improved. This study aimed to determine the effects of online infographics on improving HL among patients with type 2 DM.

METHODS

This randomized controlled trial was conducted from July 2022 to September 2022, at the primary care unit of Songklanagarind Hospital, Thailand; 30 patients with type 2 DM were randomly assigned to the experimental (n = 15; three types of infographics) and control (n = 15; three types of pamphlets) groups. Infographics and pamphlets were distributed weekly via social media platforms. The S-TOFHLA Thai version and Thai-FCCHL were used to evaluate HL. Chi-square, Fisher's exact, Wilcoxon rank-sum, t-test, paired t-test, and McNemar's chi-square tests were used.

RESULTS

The median age of 30 participants was 56 years. The mean duration of DM was 9.6 years, with a median HbA1c level of 7.5 mg%. Most participants (80%) had adequate HL in S-TOFHLA, whereas 63.3% had adequate HL in FCCHL. All participants in the infographic group who had inadequate HL in the S-TOFHLA pre-test achieved adequate HL. Meanwhile, only 50% of patients in the pamphlet group achieved adequate HL. Regarding FCCHL, 50% of patients in the infographic group and 60% in the pamphlet group who had inadequate HL in the pretest achieved adequate HL. However, no statistical significance in achieving adequate HL was found in either group. The mean differences (SD) in S-TOFHLA between before and after intervention were 12.53 (8.77; p = 0.0007) and 10.13 (9.88; p = 0.001) in the infographic and pamphlet groups, respectively. Regarding FCCHL, the mean differences (SD) were 3.47 (4.29) and 3.20 (2.91) in the infographic group (p = 0.003) and pamphlet (p = 0.002) groups, respectively. No statistical significance in the mean difference was found between both groups.

CONCLUSIONS

Novel online infographics and pamphlets did not significantly differ in achieving adequate HL among patients with type 2 DM who should receive health education about disease control and complication prevention. However, both interventions can increase and maintain HL levels. Online educational media can be appropriate during the COVID-19 pandemic. Nevertheless, further larger-scale studies should be performed to examine the impact of other DM educational media on HL promotion.

Interventions for improving health literacy in migrants

BACKGROUND

Health literacy (HL) is a determinant of health and important for autonomous decision-making. Migrants are at high risk for limited HL. Improving HL is important for equitable promotion of migrants' health.

OBJECTIVES

To assess the effectiveness of interventions for improving HL in migrants. To assess whether female or male migrants respond differently to the identified interventions.

SEARCH METHODS

We ran electronic searches to 2 February 2022 in CENTRAL, MEDLINE, Embase, PsycInfo and CINAHL. We also searched trial registries. We used a study filter for randomised controlled trials (RCTs) (RCT classifier).

SELECTION CRITERIA

We included RCTs and cluster-RCTs addressing HL either as a concept or its components (access, understand, appraise, apply health information).

DATA COLLECTION AND ANALYSIS

We used the methodological procedures recommended by Cochrane and followed the PRISMA-E guidelines. Outcome categories were: a) HL, b) quality of life (QoL), c) knowledge, d) health outcomes, e) health behaviour, f) self-efficacy, g) health service use and h) adverse events. We conducted meta-analysis where possible, and reported the remaining results as a narrative synthesis.

MAIN RESULTS

We included 28 RCTs and six cluster-RCTs (8249 participants), all conducted in high-income countries. Participants were migrants with a wide range of conditions. All interventions were adapted to culture, language and literacy. We did not find evidence that HL interventions cause harm, but only two studies assessed adverse events (e.g. anxiety). Many studies reported results for short-term assessments (less than six weeks after total programme completion), reported here. For several comparisons, there were also findings at later time points, which are presented in the review text. Compared with no HL intervention (standard care/no intervention) or an unrelated HL intervention (similar intervention but different information topic) Self-management programmes (SMP) probably improve self-efficacy slightly (standardised mean difference (SMD) 0.28, 95% confidence interval (CI) 0.06 to 0.50; 2 studies, 333 participants; moderate certainty). SMP may improve HIV-related HL (understanding (mean difference (MD) 4.25, 95% CI 1.32 to 7.18); recognition of HIV terms (MD 3.32, 95% CI 1.28 to 5.36)) (1 study, 69 participants). SMP may slightly improve health behaviours (3 studies, 514 participants), but may have little or no effect on knowledge (2 studies, 321 participants) or subjective health status (MD 0.38, 95% CI -0.13 to 0.89; 1 study, 69 participants) (low certainty). We are uncertain of the effects of SMP on QoL, health service use or adverse events due to a lack of evidence. HL skills building courses (HLSBC) may improve knowledge (MD 10.87, 95% CI 5.69 to 16.06; 2 studies, 111 participants) and any generic HL (SMD 0.48, 95% CI 0.20 to 0.75; 2 studies, 229 participants), but may have little or no effect on depression literacy (MD 0.17, 95% CI -1.28 to 1.62) or any health behaviour (2 studies, 229 participants) (low certainty). We are uncertain if HLSBC improve QoL, health outcomes, health service use, self-efficacy or adverse events, due to very low-certainty or a lack of evidence. Audio-/visual education without personal feedback (AVE) probably improves depression literacy (MD 8.62, 95% CI 7.51 to 9.73; 1 study, 202 participants) and health service use (MD -0.59, 95% CI -1.11 to -0.07; 1 study, 157 participants), but probably has little or no effect on health behaviour (risk ratio (RR) 1.07, 95% CI 0.91 to 1.25; 1 study, 135 participants) (moderate certainty). AVE may improve self-efficacy (MD 3.51, 95% CI 2.53 to 4.49; 1 study, 133 participants) and may slightly improve knowledge (MD 8.44, 95% CI -2.56 to 19.44; 2 studies, 293 participants) and intention to seek depression treatment (MD 1.8, 95% CI 0.43 to 3.17), with little or no effect on depression (SMD -0.15, 95% CI -0.40 to 0.10) (low certainty). No evidence was found for QoL and adverse events. Adapted medical instruction may improve understanding of health information (3 studies, 478 participants), with little or no effect on medication adherence (MD 0.5, 95% CI -0.1 to 1.1; 1 study, 200 participants) (low certainty). No evidence was found for QoL, health outcomes, knowledge, health service use, self-efficacy or adverse events. Compared with written information on the same topic SMP probably improves health numeracy slightly (MD 0.7, 95% CI 0.15 to 1.25) and probably improves print literacy (MD 9, 95% CI 2.9 to 15.1; 1 study, 209 participants) and self-efficacy (SMD 0.47, 95% CI 0.3 to 0.64; 4 studies, 552 participants) (moderate certainty). SMP may improve any disease-specific HL (SMD 0.67, 95% CI 0.27 to 1.07; 4 studies, 955 participants), knowledge (MD 11.45, 95% CI 4.75 to 18.15; 6 studies, 1101 participants) and some health behaviours (4 studies, 797 participants), with little or no effect on health information appraisal (MD 1.15, 95% CI -0.23 to 2.53; 1 study, 329 participants) (low certainty). We are uncertain whether SMP improves QoL, health outcomes, health service use or adverse events, due to a lack of evidence or low/very low-certainty evidence. AVE probably has little or no effect on diabetes HL (MD 2, 95% CI -0.15 to 4.15; 1 study, 240 participants), but probably improves information appraisal (MD -9.88, 95% CI -12.87 to -6.89) and application (RR 1.51, 95% CI 1.29 to 1.77) (1 study, 608 participants; moderate certainty). AVE may slightly improve knowledge (MD 8.35, 95% CI -0.32 to 17.02; low certainty). No short-term evidence was found for QoL, depression, health behaviour, self-efficacy, health service use or adverse events. AVE compared with another AVE We are uncertain whether narrative videos are superior to factual knowledge videos as the evidence is of very low certainty. Gender differences Female migrants' diabetes HL may improve slightly more than that of males, when receiving AVE (MD 5.00, 95% CI 0.62 to 9.38; 1 study, 118 participants), but we do not know whether female or male migrants benefit differently from other interventions due to very low-certainty or a lack of evidence.

AUTHORS' CONCLUSIONS

Adequately powered studies measuring long-term effects (more than six months) of HL interventions in female and male migrants are needed, using well-validated tools and representing various healthcare systems.

The roles of nurses in supporting health literacy: a scoping review

Introduction

The importance of health literacy in achieving optimum health is highly significant, particularly in the nursing profession where it is an integral part of the roles and functions of nurses. Therefore, this scoping review aims to describe the roles of nurses in promoting patient health literacy and identify the determinant factors of health literacy in nursing practices.

Methods

An integrative search was conducted through four databases, namely, ScienceDirect, ProQuest, SAGE Journal, and PubMed, using various keyword combinations such as "health literacy," "health information," "patient health literacy," "patient literacy," and "nurses." Furthermore, the inclusion criteria employed were peer-reviewed articles focused on the nursing profession, explicitly discussing health literacy related to nursing, and including original studies, such as cross-sectional, quasi-experimental, and qualitative studies. The selected review articles were all published between 2017 and 2022.

Results

In total, 13 articles met the criteria and were applied in this scoping review. Most of these discuss health literacy related to nursing practice in clinical and community settings, as well as educational institutions. Health literacy is an essential aspect of professional nursing practice. Consequently, the supportive roles of nurses include acting as caregivers, facilitators, and educators to help patients overcome their literacy limitations and attain improved wellbeing.

Conclusion

Nurses can improve the health literacy skills of patients by making health information related to their illnesses easier to access, understand, evaluate, and use. They must also recognize various factors influencing health literacy and use the factors as opportunities to optimize health literacy improvement. A health literacy approach can be applied by nurses to solve health problems and improve the quality of care for patients.

The Use of Multidimensional Nomial Logistic Model and Structural Equation Model in the Validation of the 14-Item Health-Literacy Scale in Chinese Patients Living with Type 2 Diabetes

Objective

To evaluate the psychometric properties of the 14-item health literacy scale (HL-14) in patients living with type 2 diabetes mellitus (T2DM) in clinical setting.

Methods

Cross-sectional study using item response theory and structural equation modeling (SEM) for testing the item difficulty and three dimensional-HL configurations was adopted in this study. Chinese patients living with T2DM admitted to endocrinology department of Huadong hospital were evaluated by the HL-14 including communication, functional and critical health literacy from August to December 2021.

Results

The multidimensional random coefficients multinomial logistic model indicated the difficulty settings of the scale are appropriate for the study populations, and differential item functioning was not observed for sex in the study. SEM demonstrated that the three-dimensional configuration of the scale is good in the study population (x2/df=2.698, Comparative Fit Index = 0.965, Root Mean Square Error of Approximation = 0.076, standard residual mean root = 0.042).

Conclusion

The HL-14 scale is a reliable and valid measurement, which can perform equitably across sex in evaluating the health literacy in Chinese patients living with T2DM. Moreover, the scale may help fill the gaps of multidimensional health literacy assessment and rapid screening of health literacy ability for clinical practice.

Self-Care in Korean Immigrants with Chronic Diseases: A Concept Analysis

Chronic illnesses among Korean immigrants (KIs) in the United States have been rapidly increasing, yet the concept of chronic disease self-care in this group has not been delineated. The aim of this study was to review previous research on self-care among KIs with chronic diseases and describe the concept in cultural context. Using Rodgers' Evolutionary Method, a total of 24 articles were analyzed. The definition and conceptual model of self-care in KIs with chronic diseases were proposed. The antecedents included knowledge and health literacy; social and family support; resources; patient-health care provider partnership; and elimination of cultural misbeliefs and disclosure of the disease. The attributes of the concept were aging well with diseases; treatment adherence; control and restriction; the acculturation process; care built on traditional Korean gender roles; and maintenance of mental health. The consequences involved positive physiological outcomes; self-efficacy; quality of life; and reducing worry about becoming a burden to the family. While the studied concept encompassed universal characteristics of chronic disease self-care, distinctive cultural features emerged. The findings contribute to a better understanding of chronic illness self-care in this population and the development of culturally sensitive and practical self-care interventions for KIs with chronic diseases.

Health literacy interventions among patients with chronic diseases: A meta-analysis of randomized controlled trials

OBJECTIVES

This study was conducted to determine the effectiveness and impact of health literacy interventions for patients with chronic diseases.

METHODS

We searched PubMed, Web of Science, Embase, Scopus, and EBSCO CINAHL from inception through March 2022. Eligible chronic diseases include diabetes, heart disease, cancer, and chronic obstructive pulmonary disease. RCTs were included in eligible studies to assess health literacy and other relevant health outcomes. Two investigators selected studies, extracted data, and assessed the methodological quality of included studies independently.

RESULTS

A total of 18 studies involving 5384 participants were included in the final analysis. The implementation of health literacy interventions exhibited a significant improvement in the health literacy level of individuals diagnosed with chronic diseases (SMD = 0.75, 95% CI = 0.40-1.10). Analysis of heterogeneity sources indicated statistically significant variations in the effects of interventions across different diseases and age groups (P < 0.05). However, no significant impact was observed on patients with chronic obstructive pulmonary disease (COPD), interventions with a follow-up duration exceeding three months, or application-based interventions on the health literacy level of individuals with chronic diseases. Remarkably, our findings revealed that health literacy interventions exerted a positive influence on health status (SMD = 0.74, 95% CI = 0.13-1.34), depression and anxiety (SMD = 0.90, 95% CI = 0.17-1.63), as well as self-efficacy (SMD = 0.28, 95% CI = 0.15-0.41) among patients diagnosed with chronic diseases. Furthermore, a specific analysis was conducted to evaluate the effects of these interventions on hypertension and diabetes control. The results demonstrated that health literacy interventions were more effective in enhancing hypertension control compared to diabetes control.

CONCLUSION

Health literacy interventions have demonstrated effectiveness in improving the health of patients with chronic diseases. The importance of emphasizing the quality of these interventions cannot be overstated, as factors such as appropriate intervention tools, extended intervention duration, and reliable primary care services play crucial roles in their efficacy.

Communication Dimensions of Healthcare Engagement and Patient Health Literacy for Immigrant Populations: A Systematic Review

Health literacy is an important social determinant of health. Achieving health literacy of immigrants can be critical to empower this disadvantaged population in healthcare communication. However, to achieve this goal, it is a prerequisite to examine the relationship between health literacy and patient engagement in healthcare communication. This systematic review conceptualizes behavioral, emotional, and cognitive dimensions of patient engagement in healthcare communication and examines how health literacy and patient engagement among immigrants shape each other. A systematic review was conducted to identify relevant articles from five databases between 2010 and 2020. The reviewers synthesized findings from 15 articles that met the inclusion criteria. The results indicate that communication researchers should be more attentive to the emotional dimension of patient engagement in healthcare communication and that more empirical studies are needed to evaluate the relationship between health literacy and patient engagement among immigrants. Practical implications and recommendations for future research are discussed.

Health literacy levels in patients with type 2 diabetes in an affluent Gulf country: a cross-sectional study

OBJECTIVES

To identify health literacy levels in patients with type 2 diabetes mellitus in the United Arab Emirates (UAE).

INTERVENTION

Nationwide cross-sectional survey.

SETTING AND PARTICIPANTS

Individuals with type 2 diabetes mellitus attending outpatient diabetes clinics in all emirates of the UAE were surveyed between January 2019 and May 2020. Out of 832 patients approached, 640 met the inclusion criteria and agreed to participate.

OUTCOME VARIABLES

The outcome variable of interest was the health literacy level, which was measured using the Eastern-Middle Eastern Adult Health Literacy 13 Questionnaire. The association of health literacy level with age, gender and education was conducted using the Χ² test.

RESULTS

Only 11% of respondents had adequate health literacy levels. Age and education were directly correlated with health literacy levels. Patients under age 50 years had statistically significant higher rates of marginal (106 of 238, 44.5%) and adequate literacy (67 of 238, 28.2%, p<0.001) than the older population. Participants with bachelor's or postgraduate degrees also had significantly higher adequate health literacy levels (24 of 79, 30.4%, p<0.001).

CONCLUSIONS

The low health literacy levels found in outpatients with diabetes may be a major challenge to optimising diabetes care in the UAE. In addition to health services strategies, targeted educational and behavioural interventions for the older population and those with less formal education are necessary.

The relationship between patient empowerment and related constructs, affective symptoms and quality of life in patients with type 2 diabetes: a systematic review and meta-analysis

Introduction

The aim of this systematic review is to assess the relationship between patient empowerment and other empowerment-related constructs, and affective symptoms and quality of life in patients with type 2 diabetes.

Methods

A systematic review of the literature was conducted, according to the PRISMA guidelines. Studies addressing adult patients with type 2 diabetes and reporting the association between empowerment-related constructs and subjective measures of anxiety, depression and distress, as well as self-reported quality of life were included. The following electronic databases were consulted from inception to July 2022: Medline, Embase, PsycINFO, and Cochrane Library. The methodological quality of the included studies was analyzed using validated tools adapted to each study design. Meta-analyses of correlations were performed using an inverse variance restricted maximum likelihood random-effects.

Results

The initial search yielded 2463 references and seventy-one studies were finally included. We found a weak-to-moderate inverse association between patient empowerment-related constructs and both anxiety (r = -0.22) and depression (r = -0.29). Moreover, empowerment-related constructs were moderately negatively correlated with distress (r = -0.31) and moderately positively correlated with general quality of life (r = 0.32). Small associations between empowerment-related constructs and both mental (r = 0.23) and physical quality of life (r = 0.13) were also reported.

Discussion

This evidence is mostly from cross-sectional studies. High-quality prospective studies are needed not only to better understand the role of patient empowerment but to assess causal associations. The results of the study highlight the importance of patient empowerment and other empowerment-related constructs such as self-efficacy or perceived control in diabetes care. Thus, they should be considered in the design, development and implementation of effective interventions and policies aimed at improving psychosocial outcomes in patients with type 2 diabetes.

Elements for successful implementation of a clinic-based health literacy intervention

Improving health literacy is a national public health priority. Given the context of the COVID-19 pandemic, it is even more critical for health and medical information to be clear and understandable for patients and their families. Clinic-based programs to improve health literacy need to be pragmatic, feasible, and helpful for the implementing clinic and patients. This paper describes the development, implementation, and evaluation of a pragmatic, clinic-based health literacy intervention in a safety-net clinic that serves uninsured and indigent patients. Study methods are guided by a previous pilot study and components recommended for pragmatic interventions. An electronic readiness assessment was distributed to out-patient clinics affiliated with a statewide hospital association. The AskMe3 tool was used for the intervention as it is evidence informed and relatively easy to implement. Implementation included ongoing dialogue between the clinic and the academic research team. Within the implementing clinic, data collected from patients via verbally administered questionnaires was analyzed using descriptive statistics and chi-squares. Interview data collected from the clinic director was analyzed qualitatively for themes. The implementing clinic had some of the lowest average scores of the 34 clinics who participated in the initial readiness assessment. Despite this, they were able to successfully implement the health literacy intervention during a global pandemic. Eighty-eight participants completed patient questionnaires at this clinic. Most patients (96%) agreed the AskMe3 questions helped them talk with the doctor or nurse at their current appointment. Most (99%) also perceived the AskMe3 tool to be very helpful when used in a clinical setting. The clinic director offered that the staff initially thought the intervention would be difficult to implement. However, implementation by clinic volunteers with encouragement and prioritization of health literacy by the clinic director contributed to success. When considering interventions for clinical settings, a pragmatic approach can help with selection and implementation of a program that fits with the realities on the ground. Further, frequent technical assistance can help resolve implementation barriers. Interventions utilizing tools such as AskMe3, because of their simplicity, allow creative solutions to capacity issues for clinics who see a need for health literacy improvements.

The Effect of Health Literacy Intervention on Patients with Diabetes: A Systematic Review and Meta-Analysis

Relevant studies published between January 2010 and June 2021 were identified through relevant databases, including the Science Citation Index Expanded (SCIE) database of Web of Science, PubMed, and Embase, in order to assess the effect of health literacy (HL) intervention on patients with diabetes. A total of 21 articles were eligible. The results showed that: (1) this review involved different HL assessment tools, most of which were self-designed scales and assessment tools focused on measuring functional HL. (2) The differences in glycosylated hemoglobin (HbA1c) (weighted mean difference [WMD] = -0.78, 95% confidence interval [CI]: -0.94, -0.62) and medication adherence (standardized mean difference [SMD] = 1.85, 95% CI: 0.19, 3.52) between the HL intervention group and the usual care group were statistically significant. There was no significant improvement in systolic blood pressure (SMD = -0.05, 95% CI: -0.34, 0.25). Furthermore, this review reported that self-efficacy (SMD = 0.85, 95% CI: 0.65, 1.04) was increased, and the level of HL was improved. In the assessments of risk of bias, 90% of the studies were classified as medium. The quality of the evidence of medication adherence was very low, and the reliability of the conclusions was not enough to confirm the effect of HL.

"A bit of everything": Health literacy interventions in chronic conditions - a systematic review

OBJECTIVE

To systematically evaluate health literacy (HL) interventions in chronic conditions by exploring theoretical perspectives, intervention content and effectiveness.

METHOD

We searched MEDLINE, Cochrane, CINAHL, EMBASE, ERIC, Web of Science and PsycINFO. Standardised systematic review methods were used, and sequences informing our research question were extracted and analysed. The study includes a descriptive summary of the included papers.

RESULTS

We included 39 unique interventions, with diabetes and heart disease as the most targeted chronic conditions. Fifty-four percent of papers included a definition of HL, but the studies showed significant heterogeneity of theoretical underpinnings, modes, measures and content. We identified 23 HL measures, mostly assessing functional HL. The HL interventions were often more complex than the measures indicated. A significant change in HL was found in 28 studies. Study quality was generally poor.

CONCLUSIONS

Interventions optimizing HL appear important to improve health outcomes in chronic conditions. To ensure cumulative knowledge development of this field we need theory-based interventions, consistency in methods and more tailored and comprehensive measures to capture the interventions' complexity.

PRACTICE IMPLICATIONS

A more valid understanding of HL interventions and measurements is needed to reach an agreed understanding of their components and intentions.

Development of a short-form Chinese health literacy scale for low salt consumption (CHLSalt-22) and its validation among hypertensive patients

Background

With the accelerated pace of people’s life and the changing dietary patterns, the number of chronic diseases is increasing and occurring at a younger age in today’s society. The speedily rising hypertensive patients have become one of the main risk factors for chronic diseases. People should focus on health literacy related to salt consumption and reach a better quality of life. Currently, there is a lack of local assessment tools for low salt consumption in mainland China.

Objective

To develop a short-form version of the Chinese Health Literacy Scale For Low Salt Consumption instrument for use in mainland China.

Methods

A cross-sectional design was conducted on a sample of 1472 people in Liaoxi, China. Participants completed a sociodemographic questionnaire, the Chinese version of the CHLSalt-22, the measuring change in restriction of salt (sodium) in the diet in hypertensives (MCRSDH-SUST), the Brief Illness Perception Questionnaire (BIPQ), and the Benefit-Finding Scales (BFS) to test the hypothesis. Exploratory factor analysis and confirmatory factor analyses were performed to examine the underlying factor structure of the CHLSalt-22. One month later, 37 patients who participated in the first test were recruited to evaluate the test-retest reliability.

Results

The CHLSalt-22 demonstrated adequate internal consistency, good test-retest reliability, satisfactory construct validity, convergent validity and discriminant validity. The CHLSalt-22 count scores were correlated with age, sex, body mass index (BMI), education level, income, occupation, the Measuring Change in Restriction of Salt (sodium) in Diet in Hypertensives (MCRSDH-SUST), the Brief Illness Perception Questionnaire (BIPQ), and the Benefit-Finding Scales (BFS).

Conclusion

The results indicate that the Chinese Health Literacy Scale For Low Salt Consumption (CHLSalt-22) version has good reliability and validity and can be considered a tool to assess health literacy related to salt consumption in health screenings.

Redesigning culturally tailored intervention in the precision health era: Self-management science context

BACKGROUND

Nurse scientists have significantly contributed to health equity and ensuring cultural tailoring of interventions to meet unique needs of individuals. Methodologies for cultural tailoring of self-mangament interventions among marginalized populations have limitedly accommodated intersectionality and group heterogeneity when addressing health needs.

PURPOSE

Identify methodological limitations in cultural tailoring of interventions among priority populations and issue recommendations on cultural elements that researchers can target to ensure valid cultural tailoring approaches.

METHODS

Synthesis of literature on health equity, self-management, and implementation and dissemination research.

FINDINGS

Among priority populations, intersectionality and group heterogeneity has made group-based cultural tailoring approaches less effective in eliciting desirable health outcomes. Precision health methodology could be useful for cultural tailoring of interventions due to the methodology's focus on individual-level tailoring approaches.

DISCUSSION

We offer ways to advance health equity research using precision health approaches in cultural tailoring through targeting unique elements of culture and relevant psychosocial phenotypes.

Communicating with Community: Health Disparities and Health Equity Considerations

This article explores why communicating with communities is important to the health of individuals as well as public health, and best practices of how. We outline the use of relevant theoretic frameworks, understanding the role of technological contextual changes, trust despite misinformation, health and digital literacy skills, and working with the community for effective reciprocal communication. Strategies for developing community communication are also enumerated and applied to addressing health disparities.

The Relationships Among Health Literacy, Illness Perception, and Diabetes Self-Care in Korean-Speaking Immigrants With Diabetes

Diabetes self-care is explained as an illness-related coping behavior. Health literacy is an important predictor in self-care behaviors. However, little is known about their association with illness perception in Korean immigrants with diabetes. This study aimed to examine the relationships among health literacy, illness perception, and diabetes self-care in Korean-speaking immigrants with diabetes. This cross-sectional study was conducted in 2020. A convenience sample of 52 Korean adults with diabetes in Dallas-Fort Worth areas completed a survey. Data were analyzed using SPSS (version 25) with statistical significance at α < .05. The mean of health literacy was high (11.1, SD = 1.1, ranges 0-12) although risk of type II error with the small sample size. There were no statistically significant associations between health literacy, illness perception, and diabetes self-care. Language barriers are considered a literacy issue, but health literacy and limited English proficiency must be approached differently by health care providers.

2022 National Standards for Diabetes Self-Management Education and Support

PURPOSE

The National Standards for Diabetes Self-Management Education and Support (DSMES) provide guidance and evidence-based, quality practice for all DSMES services. Due to the dynamic nature of health care and diabetes research, the National Standards are reviewed and revised approximately every 5 years by key stakeholders and experts within the diabetes care and education community. For each revision, the Task Force is charged with reviewing the current National Standards for appropriateness, relevance, and scientific basis and making updates based on current evidence and expert consensus. In 2021, the group was tasked with reducing administrative burden related to DSMES implementation across diverse care settings.

CONCLUSION

The evidence supporting the 2022 National Standards clearly identifies the need to provide person-centered services that embrace cultural differences, social determinants of health, and the ever-increasing technological engagement platforms and systems. Payers are invited to review the National Standards as a tool to inform and modernize DSMES reimbursement requirements and to align with the evolving needs of people with diabetes (PWD) and physicians/other qualified health care professionals. The American Diabetes Association and the Association of Diabetes Care & Education Specialists strongly advocate for health equity to ensure all PWD have access to this critical service proven to improve outcomes both related to and beyond diabetes. The 2022 National Standards update is meant to be a universal document that is easy to understand and can be implemented by the entire health care community. DSMES teams in collaboration with primary care have been shown to be the most effective approach to overcome therapeutic inertia.

Systematic Review of Self-Monitoring of Blood Glucose in Patients with Type 2 Diabetes

BACKGROUND

The benefit of self-monitoring of blood glucose in reducing HbA1c in non-insulin-treated participants remains unclear. HbA1c may be improved in this population with self-monitoring.

OBJECTIVE

To conduct a meta-analysis of the effect in non-insulin-treated participants with type 2 diabetes of self-monitoring of blood glucose versus usual care, structured versus unstructured self-monitoring of blood glucose on glycemic control, and use of self-monitoring of blood glucose readings used to adjust therapy versus usual care.

METHODS

Medline, Embase, and Cochrane Central were electronically searched to identify articles published from January 1, 2000, to June 3, 2020. Trials investigating changes in HbA1c were selected. Screening was performed independently by two investigators. Two investigators extracted HbA1c at baseline and follow-up for each trial.

RESULTS

Nineteen trials involving 4,965 participants were included. Overall, self-monitoring of blood glucose reduced HbA1c. Preplanned subgroup analysis showed that using self-monitoring of blood glucose readings to adjust therapy contributed significantly to the reduction. No significant improvement in HbA1c was shown in self-monitoring of blood glucose without therapy adjustment. The same difference was observed in structured versus unstructured self-monitoring of blood glucose.

DISCUSSION

HbA1c is improved with therapy adjustment based on structured self-monitoring of blood glucose readings. Implications are for clinicians to prescribe structured self-monitoring of blood glucose to modify therapy adjustment based on the readings and not prescribe unstructured self-monitoring of blood glucose. Participants with suboptimal glycemic control may benefit most. A self-monitoring of blood glucose regimen that improves clinical- and cost-effectiveness is presented. Future studies can investigate this regimen specifically.

Development of a Diabetes-Focused Print Health Literacy Scale Using the Rapid Estimate of Adult Literacy in Medicine Model

BACKGROUND

A diabetes mellitus (DM)-specific health literacy (HL) measure that focuses on both oral and print HL is needed in clinical and research settings.

OBJECTIVE

The present study developed a psychometrically sound DM-specific HL instrument that measures oral and print HL.

METHODS

We developed the measure in three steps. First, we reviewed clinical guidelines and conducted focus groups with experts to generate items. Next, we conducted a psychometric evaluation of the scale in three language versions (English, Spanish, and Korean). Lastly, we identified and removed items with potential cultural bias and duplicate functions to produce shorter versions of the scale, using item response theory (IRT).

KEY RESULTS

We initially developed an 82-item DM-specific oral HL scale using the Rapid Estimate of Adult Literacy in Medicine (DM-REALM) model. To improve the clinical utility of the DM-REALM, we created shorter forms, a 40-item and 20-item version, and evaluated them by using IRT. All DM-REALM versions had high Cronbach alphas (.985, .974, and .945, respectively) and yielded sufficient convergent validity by positive correlations with existing functional HL scale (r = .49, p < .001), education (r = .14, p = .14 to r = .54, p < .001), and DM knowledge (r = .04, p = .70 to r = .36, p < .001). DM-REALM also demonstrated adequate sensitivity as an intervention evaluation tool that captures the changes induced by an intervention.

CONCLUSIONS

All forms of the DM-REALM tool were reliable, valid, and clinically useful measures of HL in the context of DM care. Both researchers and clinicians can use this tool to assess DM-specific HL across multiple racial and ethnic populations. [HLRP: Health Literacy Research and Practice. 2020;4(4):e237-e249.] PLAIN LANGUAGE SUMMARY: This article reported the process and findings of a newly developed health literacy scale for people with diabetes mellitus using three different language versions. Both long and short versions of the scale demonstrated adequate validity and reliability.

Health literacy and quality of life in hospitalized heart failure patients: a cross-sectional study

INTRODUCTION

Heart Failure (HF) treatment may be improved by good knowledge of the disease (Health Literacy) that, despite the well-established role on improving self-care, preventing complications and avoiding worse outcomes, has little evidence on affecting QoL of HF patients. Therefore, the objective of the present study was to evaluate the impact of Health Literacy on QoL in hospitalized HF patients.

METHODOLOGY

A cross-sectional exploratory study was conducted with HF patients hospitalized at a public cardiological hospital. Health Literacy was assessed using the "Questionnaire about Heart Failure Patients' Knowledge of Disease" and QoL using the "Minnesota Living with Heart Failure Questionnaire" (MLHFQ). The association between Health Literacy and QoL was assessed by linear regression (P<0.05).

RESULTS

50 patients were included in the study; the mean Health Literacy score was 34.2 ± 15.1 (the majority presenting acceptable or better knowledge). The mean MLHFQ score was 73.5 ± 19.8. The one-year hospital readmission rate (β=+3.8; P=0.009) and the patients' Health Literacy score (β=-0.4; P=0.024) or good knowledge category (β=-20.2; P=0.016) were independently associated with QoL.

CONCLUSION

While the readmission rate was inversely associated with QoL, the better the HF knowledge the better QoL in hospitalized HF patients.

Establishing the efficacy of interventions to improve health literacy and health behaviours: a systematic review

Background

The primary aim of this review was to establish whether health literacy interventions, in adults, are effective for improving health literacy. Two secondary aims assessed the impact of health literacy interventions on health behaviours and whether health literacy interventions have been conducted in cardiovascular patients.

Methods

A systematic review (Prospero registration: CRD42018110772) with no start date running through until April 2020. Eligible studies were conducted in adults and included a pre/post measure of health literacy. Medline, Embase, Eric, PsychINFO, CINAHL, Psychology and Behavioural Science, HMIC, Web of Science, Scopus, Social Care Online, NHS Scotland Journals, Social Policy and Practice, and Global Health were searched. Two thousand one hundred twenty-seven papers were assessed, and 57 full text papers screened to give 22 unique datasets from 23 papers. Risk of bias was assessed regarding randomisation, allocation sequence concealment, blinding, incomplete outcome data, selective outcome reporting and other biases. Intervention reporting quality was assessed using the TIDieR checklist.

Results

Twenty-two studies were included reporting on 10,997 participants in nine countries. The majority of studies (14/22) were published in 2018 or later. Eight studies (n = 1268 participants) also reported on behavioural outcomes. Health literacy interventions resulted in improvements in at least some aspect of health literacy in 15/22 studies (n = 10,180 participants) and improved behavioural outcomes in 7/8 studies (n = 1209 participants). Only two studies were conducted with cardiovascular patients. All studies were at risk of bias with 18 judged as high risk. In addition, there was poor reporting of intervention content with little explication of the theoretical basis for the interventions.

Conclusions

Health literacy interventions can improve health literacy and can also lead to changes in health behaviours. Health literacy interventions offer a way to improve outcomes for populations most at risk of health inequalities. Health literacy is a developing field with very few interventions using clear theoretical frameworks. Closer links between health literacy and behaviour change theories and frameworks could result in higher quality and more effective interventions.
