The Association of Health Literacy with Illness and Medication Beliefs among Patients with Chronic Obstructive Pulmonary Disease

Relationship between health literacy and health-related quality of life in Korean adults with chronic diseases

Inadequate health literacy is a risk factor for poor health outcomes and health-related quality of life (HRQoL). So far, the impact of health literacy on HRQoL has been examined for only a few chronic conditions. In this contribution, the relationship between health literacy and HRQoL in Korean adults with chronic conditions is examined using data of the cross-sectional Korea Health Panel Survey from 2021. Health literacy was measured with the 16-item European Health Literacy Survey Questionnaire (HLS-EU-Q16) and HRQoL with the European Quality of Life-5 Dimensions (EQ-5D). Multiple linear regression model was run for the EQ-5D index as the dependent variable. Multiple logistic regression models were implemented for responses to the individual EQ-5D items. 30.8%, 24.6%, and 44.6% of participants had inadequate, marginal, and adequate levels of health literacy, respectively. The EQ-5D index increases with marginal (B = 0.018, p<0.001) and adequate literacy (B = 0.017, p<0.001) compared to inadequate literacy. People with adequate or marginal literacy were more likely to report no problem with mobility (odds ration [OR] = 1.5; p<0.001), self-care (OR = 1.6; p<0.05), and usual activities (OR = 1.6 for adequate; OR = 1.4 for marginal; p<0.01) than those with inadequate literacy. Adequate health literacy was associated with an increased likelihood of having no problem with anxiety and depression (OR = 1.4; p<0.05). In conclusion, inadequate health literacy is prevalent among Korean adults with chronic diseases. Adequate health literacy is associated with better HRQoL and a protective factor for four dimensions of EQ-5D (mobility, self-care, usual activities, and anxiety/depression).

Assessing the interrelationship between asthma and obesity self-management behaviors

Asthma and obesity are common coexisting conditions with increasing prevalence and substantial morbidity. This study examines the inter-relationship between illness and treatment beliefs in asthma and obesity and how they influence self-management behaviors. Overweight and obese adults ≥ 18 years with asthma were recruited from primary care and pulmonary practices in New York, NY and Denver, CO (n = 219). Path analysis was used to examine the relationship between asthma, weight and exercise-related illness and medication beliefs and SMB. Necessity beliefs about asthma medications and diet were associated with better medication adherence and healthier dietary behaviors (β = 0.276, p = < 0.001, β = 0.148, p = 0.018 respectively) whereas concerns about these self-care activities were associated with poorer adherence and worse dietary behaviors (β = - 0.282, p < 0.001, β = - 0.188, p = 0.003 respectively). We found no statistically significant association of exercise behaviors with any other weight or asthma illness or treatment beliefs. Our study demonstrates that necessity and concerns about treatment are associated with adherence in asthma and obesity. The lack of association of exercise behaviors with any asthma or weight related beliefs may reflect limited awareness of the impact of weight on asthma and warrants additional research.

Accuracy of Expected Symptoms and Subsequent Quality of Life Measures Among Adults With COPD

Importance

Patients' expectations for future health guide their decisions and enable them to prepare, adapt, and cope. However, little is known about how inaccurate expectations may affect patients' illness outcomes.

Objective

To assess the association between patients' expectation inaccuracies and health-related quality of life.

Design, Setting, and Participants

This cohort study of patients with severe chronic obstructive pulmonary disease (COPD) was conducted from 2017 to 2021, which included a 24-month follow-up period. Eligible participants received outpatient primary care at pulmonary clinics of a single large US health system. Data were analyzed between 2021 and 2023.

Exposure

Expectation accuracy, measured by comparing patients' self-reported expectations of their symptom burden with their actual physical and emotional symptoms 3, 12, and 24 months in the future.

Main Outcome and Measure

Health-related quality of life, measured by the St George's Respiratory Questionnaire-COPD at 3, 12, and 24 months.

Results

A total of 207 participants were included (median age, 65.5 years [range, 42.0-86.0 years]; 120 women [58.0%]; 118 Black [57.0%], 79 White [38.2%]). The consent rate among approached patients was 80.0%. Most patients reported no or only limited discussions of future health and symptom burdens with their clinicians. Across physical and emotional symptoms and all 3 time points, patients' expectations were more optimistic than their experiences. There were no consistent patterns of measured demographic or behavioral characteristics associated with expectation accuracy. Regression models revealed that overoptimistic expectations of future burdens of dyspnea (linear regression estimate, 4.68; 95% CI, 2.68 to 6.68) and negative emotions (linear regression estimate, -3.04; 95% CI, -4.78 to 1.29) were associated with lower health-related quality of life at 3 months after adjustment for baseline health-related quality of life, forced expiratory volume over 1 second, and interval clinical events (P < .001 for both). Similar patterns were observed at 12 months (dyspnea: linear regression estimate, 2.41; 95% CI, 0.45 to 4.37) and 24 months (negative emotions: linear regression estimate, -2.39; 95% CI, -4.67 to 0.12; dyspnea: linear regression estimate, 3.21; 95% CI, 0.82 to 5.60), although there was no statistically significant association between expectation of negative emotions and quality of life at 12 months.

Conclusions and Relevance

In this cohort study of patients with COPD, we found that patients are overoptimistic in their expectations about future negative symptom burdens, and such inaccuracies were independently associated with worse well-being over time. Developing and implementing strategies to improve patients' symptom expectations may improve patient-centered outcomes.

Association between cultural capital and health literacy during the COVID-19 pandemic among community residents in China: the mediating effect of social capital

Background

Health literacy is crucial for managing pandemics such as COVID-19 and maintaining the health of the population; our goal was to investigate the impact of cultural capital on health literacy during the COVID-19 pandemic among community residents and to further examine the mediating role of social capital in the relationship between cultural capital and health literacy.

Methods

A cross-sectional study was conducted among 1,600 community residents selected in Chongqing, China using a stratified random sampling method. Data were gathered through a questionnaire survey, including sociodemographic characteristics, cultural capital, social capital, and health literacy. Chi-square analysis, one-way ANOVA, t-test, and hierarchical linear regression were used to analyze the level of health literacy among community residents and the related elements; the structural equation model (SEM) was used to explore the influential mechanisms of health literacy and explore whether social capital acted as a mediator in the relationship between cultural capital and health literacy.

Results

Cultural capital, community participation, community trust, reciprocity, and cognitive social capital had a significant positive effect on health literacy. In addition, the results of SEM indicated that cultural capital not only directly influences health literacy (β = 0.383, 95% CI = 0.265-0.648), but also indirectly influences health literacy through three types of social capital (β = 0.175, 95% CI = 0.117-0.465; β = 0.191, 95% CI = 0.111-0.406; β = 0.028, 95% CI = 0.031-0.174); its mediating effect accounting for 50.7% of the overall effect.

Conclusions

Our results highlight the empirical link between cultural capital and health literacy, and suggest that social capital mediates this connection. These findings suggest that governments and communities should focus on the construction of community cultural capital and provide residents with better social capital to improve their health literacy to prepare for future pandemics.

Exploring the Perspectives and Experiences of Older Adults With Asthma and Chronic Obstructive Pulmonary Disease Toward Mobile Health: Qualitative Study

BACKGROUND

The use of mobile health (mHealth) in asthma and chronic obstructive pulmonary disease (COPD) is growing, and as the population ages, a greater number of older adults stand to benefit from mHealth-enhanced airway disease care. Though older adults are a heterogeneous population of health technology users, older age represents a potential barrier to health technology adoption, and there is currently a lack of knowledge on how older age influences mHealth use in asthma and COPD.

OBJECTIVE

In this qualitative study, we sought to explore the experiences and perspectives of adults who were aged 65 years and older with asthma and COPD toward mHealth use.

METHODS

Semistructured individual interviews were conducted with adults who were aged 65 years and older with asthma or COPD and owned a smartphone. Applying phenomenological methodology, we analyzed interview transcripts in order to develop themes and propose an essential experience of mHealth use among older adults with airway disease. We then summarized our qualitative findings and proposed strategies to leverage our results in order to guide future research and implementation efforts targeting older adults' use of airway mHealth.

RESULTS

Twenty participants (mean age 79.8, SD 4.4 years) were interviewed. Participants described a central tension between (1) the perception that mHealth could help maintain independence throughout aging and (2) an apprehension toward the ways in which mHealth could negatively affect established health care experiences. Several elements of these 2 themes are absent from previous research focusing on younger adults with asthma and COPD. The individual elements of these 2 themes informed potential strategies to optimize future older adults' use of asthma and COPD mHealth tools.

CONCLUSIONS

Focusing on the perspectives and experiences of older adults with asthma and COPD in their use of mHealth identified novel understandings of health technology use in this important demographic in need of greater care. These lessons were translated into potential strategies that will need to be objectively evaluated in future airway mHealth research, development, and implementation efforts.

Relationship Between Medication Literacy and Beliefs Among Persons with Type 2 Diabetes Mellitus in Guangdong, China

Purpose

To establish the relationship between medication literacy and medication beliefs among persons with type 2 diabetes mellitus (T2DM).

Patients and methods

A cross-sectional survey of 246 patients with T2DM was conducted between April and November 2022 at a tertiary hospital in Dongguan City, Guangdong Province, China. Subsequently, these patients were administered the General Information Questionnaire, the Chinese version of Medication Literacy Assessment Scale, and the Chinese version of Beliefs about Medicines Questionnaire-Specific via survey.

Results

The medication literacy score of patients with T2DM was 7.82±3.007, and the medication beliefs score was 2.26±4.011. The Pearson correlation analysis revealed a statistically significant but weakly positive correlation (r = 0.271, P < 0.001) between medication literacy and beliefs among patients diagnosed with T2DM. However, there was no significant correlation found between medication literacy and necessity (r = -0.021, P > 0.05), while a lowly negative correlation was observed between medication literacy and concerns (r = -0.307, P < 0.001). Moreover, the multiple linear regression analysis indicated that medication literacy, age, education level, and duration of medication usage were all significant factors influencing patients' medication beliefs (all P < 0.05). Together, these variables accounted for 15.3% of the total variance observed in the regression equation.

Conclusion

The study found a positive correlation between medication literacy and beliefs, and a negative correlation between medication literacy and concerns. These results indicate that enhancing medication literacy can improve medication adherence among individuals with T2DM by reducing concerns and strengthening medication beliefs.

Illness perception, health literacy, self-efficacy, adherence and quality of life in patients with intermittent claudication - a longitudinal cohort study

BACKGROUND

Patients with intermittent claudication need lifelong treatment with secondary prevention to prevent cardiovascular events and progression of atherosclerotic disease. Illness perception, health literacy, self-efficacy, adherence to medication treatment, and quality of life are factors influencing patients' self-management. Knowledge of these factors could be important when planning for secondary prevention in patients with intermittent claudication.

AIM

to compare illness perception, health literacy, self-efficacy, adherence to treatment, and quality of life in in patients with intermittent claudication.

METHODS

A longitudinal cohort study was conducted with 128 participants recruited from vascular units in southern Sweden. Data were collected through medical records and questionnaires regarding illness perception, health literacy, self-efficacy, adherence to treatment, and quality of life.

RESULTS

In the subscales in illness perception, patients with sufficient health literacy reported less consequences and lower emotional representations of the intermittent claudication. They also reported higher self-efficacy and higher quality of life than patients with insufficient health literacy. In comparison between men and women in illness perception, women reported higher illness coherence and emotional representations associated with intermittent claudication compared to men. A multiple regression showed that both consequences and adherence were negative predictors of quality of life. When examining changes over time, a significant increase in quality of life was seen between baseline and 12 months, but there were no significant differences in self-efficacy..

CONCLUSION

Illness perception differs in relation to level of health literacy and between men and women. Further, the level of health literacy seems to be of importance for patients' self-efficacy and quality of life. This illuminates the need for new strategies for improving health literacy, illness perception, and self-efficacy over time. For example, more tailored information regarding secondary prevention could be provided to strengthen self-management to further improve quality of life in patients with intermittent claudication.

The indirect influence of 'invisible' support on pulmonary function among adults with chronic obstructive pulmonary disease

Individuals living with chronic obstructive pulmonary disease (COPD) often require support from family or friends. We examined whether invisible support - support that is provided but goes unnoticed - is related to pulmonary function, and whether this association is mediated by depressive symptoms and illness perceptions. Sixty-six dyads of individuals with COPD and their informal caregivers reported on receipt and provision of support, respectively. Those with COPD completed measures of depressive symptoms, illness perceptions and pulmonary function. Although invisible support was not directly related to pulmonary function, mediation analyses revealed a combined indirect effect through lower depressive symptoms and less negative illness perceptions. Interventions teaching skillful delivery of support to caregivers may reduce depressive symptoms and threatening illness cognitions, which may contribute to improvements in symptom burden among patients with COPD.

IMplementing Predictive Analytics towards efficient COPD Treatments (IMPACT): protocol for a stepped-wedge cluster randomized impact study

INTRODUCTION

Personalized disease management informed by quantitative risk prediction has the potential to improve patient care and outcomes. The integration of risk prediction into clinical workflow should be informed by the experiences and preferences of stakeholders, and the impact of such integration should be evaluated in prospective comparative studies. The objectives of the IMplementing Predictive Analytics towards efficient chronic obstructive pulmonary disease (COPD) treatments (IMPACT) study are to integrate an exacerbation risk prediction tool into routine care and to determine its impact on prescription appropriateness (primary outcome), medication adherence, quality of life, exacerbation rates, and sex and gender disparities in COPD care (secondary outcomes).

METHODS

IMPACT will be conducted in two phases. Phase 1 will include the systematic and user-centered development of two decision support tools: (1) a decision tool for pulmonologists called the ACCEPT decision intervention (ADI), which combines risk prediction from the previously developed Acute COPD Exacerbation Prediction Tool with treatment algorithms recommended by the Canadian Thoracic Society's COPD pharmacotherapy guidelines, and (2) an information pamphlet for COPD patients (patient tool), tailored to their prescribed medication, clinical needs, and lung function. In phase 2, we will conduct a stepped-wedge cluster randomized controlled trial in two outpatient respiratory clinics to evaluate the impact of the decision support tools on quality of care and patient outcomes. Clusters will be practicing pulmonologists (n ≥ 24), who will progressively switch to the intervention over 18 months. At the end of the study, a qualitative process evaluation will be carried out to determine the barriers and enablers of uptake of the tools.

DISCUSSION

The IMPACT study coincides with a planned harmonization of electronic health record systems across tertiary care centers in British Columbia, Canada. The harmonization of these systems combined with IMPACT's implementation-oriented design and partnership with stakeholders will facilitate integration of the tools into routine care, if the results of the proposed study reveal positive association with improvement in the process and outcomes of clinical care. The process evaluation at the end of the trial will inform subsequent design iterations before largescale implementation.

Engaging Ethnically Diverse Populations in Self-Management Interventions for Chronic Respiratory Diseases: A Narrative Review

The burden of chronic respiratory diseases continues to rise globally. Comprehensive management relies on a combination of treatment approaches including patient self-management, where health professionals are required to educate and support patients to take control of their disease. When self-management interventions are suitably directed and effectively executed, outcomes point to increases in quality of life and a reduction in unscheduled or emergency consultations for people living with chronic respiratory disease. However, despite these positive gains, the literature reveals poor trends of engagement with this management approach and reduced access to appropriately designed programs for people from ethnically diverse populations, including migrants and refugees. The purpose of this review article is to discuss factors influencing engagement in chronic respiratory disease self-management among people from ethnically diverse backgrounds and to propose strategies to improve the participation of this population in these interventions in the future.

Self-regulatory coping among community dwelling older adults with multiple chronic conditions

Objectives

Many older adults with multiple chronic conditions (MCC) frequently experience hospitalizations, functional limitations, and poor quality of life. Outcomes may be improved by promoting self-regulation, which may individuals respond to health threats and manage their health conditions. The aim of this study was to describe self-regulatory coping among older adults with MCC.

Methods

A qualitative descriptive study using semi-structured interviews and content analysis and guided by the Common-Sense Self-Regulation Model. Seventeen community-dwelling older adults with two or more chronic conditions participated in our study.

Results

Three themes were developed from the analysis: (1) "I don't think about it unless something happens": coping in the absence of a health event, (2) "doing what I am supposed to do": coping during a health event, and (3) "How do I know if what I did works?": appraisal of coping success.

Discussion

Self-regulatory coping was influenced by individual beliefs and experiences (illness representations), context, self-efficacy and availability of support and resources to cope with MCC. These findings suggest implications for clinical practice and future self-regulation interventions for older adults with MCC.

The predictors of COVID-19 preventive health behaviors among adolescents: the role of health belief model and health literacy

Aim

The present study aimed to evaluate the predictive role of the Health Belief Model (HBM) constructs and health literacy (HL) in shaping the coronavirus disease 2019 (COVID-19) preventive health behaviors (PHBs) among adolescents.

Methods

This cross-sectional study was conducted with 503 adolescent girls and boys, randomly selected via cluster sampling. For this purpose, the data were collected online through four research tools, including the demographic-clinical characteristics information questionnaire, the COVID-19 PHB Scale based on HBM, and the Health Literacy Scale for COVID-19. The data analysis was then performed by regression analysis along with the structural equation modeling (SEM), considering the significance level of 0.05.

Results

The regression analysis results demonstrated that following the one-unit increase in the values of self-efficacy and cues to action, the COVID-19 PHBs elevated by 0.063 and 0.078 units, respectively. In addition, the COVID-19 PHBs subsided by 0.018 with the rise in the value of perceived barriers (P < 0.001). According to the path analysis, the direct path from the COVID-19-related HL to the COVID-19 PHBs (B = 0.097, β = 0.087, 95% confidence interval [CI] = 0.005 to 0.189) was significant. Furthermore, the indirect path from the COVID-19-related HL to the COVID-19 PHBs through perceived susceptibility (B = 0.017, β = 0.015, 95% CI = 0.001 to 0.032), perceived barriers (B = 0.029, β = 0.026, 95% CI = 0.004 to 0.055), self-efficacy (B = 0.094, β = 0.084, 95% CI = 0.031 to 0.156), and cues to action (B = 0.153, β = 0.137, 95% CI = 0.092 to 0.215) was significant.

Conclusion

In keeping with the study results, it is essential to take some effective measures to boost the HBM constructs and HL among adolescents to improve their PHBs during pandemics such as COVID-19.

Treatment Burden Discussion in Clinical Encounters: Priorities of COPD Patients, Carers and Physicians

Purpose

Many people with chronic obstructive pulmonary disease (COPD) feel overburdened with the treatment and management of their illness. Although research has begun to shed light on how COPD patients experience treatment burden, most of what we know is limited to personal experiences of patients. The aim of this study is to identify and prioritise areas of treatment burden that should be discussed during the clinical encounter from the perspectives of COPD patients, carers, and respiratory physicians.

Patients and Methods

Data were collected from participants using the nominal group technique. Five nominal group sessions were conducted in total (n = 31); three sessions with patients (n = 18), one with carers (n = 7) and another with respiratory physicians (pulmonologists or chest physicians) (n = 6). Each session was recorded and analyzed using thematic analysis.

Results

Going beyond understanding patients’ and carers’ experiences of treatment burden, this study offers a practical viewpoint of what should be discussed in a clinical encounter. Each group of participants contextualized treatment burden issues for discussion from their own perspectives. There was strong agreement, however, across the groups that difficulties accessing healthcare, lack of education and information, and worry about COPD treatment and prognosis were the most important treatment burden priorities for discussion.

Conclusion

Understanding and creating opportunities to discuss these issues in a clinical encounter is important in not only reducing treatment burden but also improving health outcomes and quality of life for COPD patients and their carers.

Exploring patients' and health professionals' perspectives on health literacy needs in the context of chronic obstructive pulmonary disease

OBJECTIVE

Persons with chronic obstructive pulmonary disease (COPD) require complex follow-up by healthcare professionals (HCPs) and may experience several health literacy (HL) needs. This study aimed to explore such needs in people with COPD and the HCPs who care for them.

METHODS

From October 2016 to August 2017 a qualitative study with four focus groups (FG) were performed in people with COPD (n = 14) and three in multidisciplinary HCPs (n = 21). An inductive thematic analysis was used to investigate HL needs.

RESULTS

Four HL needs emerged: 1) strengthening the feeling of security; 2) combating the burden of insufficient knowledge on COPD and lack of informational flow; 3) supporting motivation for endurance and self-management; and 4) strengthening dignity.

DISCUSSION

This study highlights a gap between people with COPD who express important HL needs and HCPs' capabilities to care for these needs. For HCPs to increase HL in such cases, HCPs need to improve their own HL. It is essential to find solutions on how to improve HL in HCPs who care for people with COPD and to increase the availability of interventions that increase HL in COPD. Education programs, health organizations, and governments should be aware of HL needs in such situations.

Promoting Health Literacy and Perceived Self-Efficacy in People with Chronic Obstructive Pulmonary Disease

Background

Chronic Obstructive Pulmonary Disease (COPD) is an irreversible condition and it is of great importance for the patients to practice self-care. Given the impact of inadequate health literacy on people's self-efficacy in a self-care program, the aim of this study was to improve health literacy and self-efficacy in people with COPD.

Materials and Methods

The present quasi-experimental study was conducted on 70 patients with COPD admitted to Shahrekord educational hospitals in 2019. Using random allocation software, the samples were randomly divided into intervention and control groups. Data collection tools included three questionnaires including demographic, health literacy, and perceived self-efficacy questionnaires. A training program, with three weekly sessions of theoretical and practical trainings, was conducted for the intervention group in classes in the hospital. The time of each session was 40 min. Data were collected three times i.e., before, immediately after, and three months after the trainings. Data were analyzed by means of SPSS 21 statistical software using descriptive and inferential statistics.

Results

Before the intervention, the mean scores of perceived self-efficacy and health literacy did not differ significantly between the two groups, but after the intervention, the scores of the members in the intervention group increased significantly (f = 62.15, p < 0.05).

Conclusions

The results of the study indicated an increase in the scores of perceived self-efficacy and health literacy in people with COPD. The use of targeted educational interventions can have a positive effect on the treatment and control of the disease.

Health literacy and quality of life in Iranian persons with COPD

BACKGROUND

Chronic obstructive pulmonary disease is a progressive disorder with significant physical, psychological, and social consequences and adversely affects the persons' quality of life (QOL).

OBJECTIVES

This study aimed to determine the health literacy (HL) and QOL of persons with COPD and some of the contributing factors.

METHODS

A cross-sectional study was conducted from May to December 2019 on 270 persons with COPD referring to Shahid-Beheshti Hospital of Kashan, Iran. Data were collected using a demographic questionnaire, the 33-item Health Literacy Questionnaire of the Urban Population of Iran (with a total score ranging from 33 to 165, higher score indicates higher HL) and the 50-item St. George's Respiratory Questionnaire for assessing the QOL (with a total score ranging from zero to 100, greater score means lower QOL). Descriptive statistics, Pearson and Spearman correlation coefficient, Chi-square test, t-test, analysis of variance, and linear regression analysis were used to analyze the data.

RESULTS

The mean age and the mean duration of COPD were 59.48±13.31 and 3.85±3.47 years, respectively. The mean HL score and the mean QOL were 81.44±23.89 and 57.41±10.70, respectively. A significant correlation was found between HL and QOL (r=-0.21, p<0.001).

CONCLUSION

Participants had moderate levels of HL and QOL. There was a significant correlation between HL and QOL. Health care providers are recommended to take effective steps to improve the HL of persons with COPD by developing comprehensive educational programs for them.

Promoting Acceptance and Adherence to Noninvasive Ventilation in Chronic Obstructive Pulmonary Disease: A Randomized Controlled Trial

OBJECTIVE

People with chronic obstructive pulmonary disease (COPD) may suffer from anxiety, depression, low quality of life, and cognitive deficits that could play a role in their clinical conditions. These situations could be worsened during the adaptation process to a new treatment such as noninvasive ventilation (NIV), which is often rejected or inappropriately used. The study aimed to analyze the impact of a brief psychological support intervention on adherence to NIV among patients with COPD.

METHODS

A two-branch randomized controlled trial was conducted on 90 patients with COPD who had an indication for NIV. The experimental group received cognitive behavioral therapy support, including counseling, relaxation, and mindfulness-based exercises. Controls received standard care and watched educational videos. The course had been structured for four to eight meetings at the hospital, at home, and/or via telemedicine.

RESULTS

The psychological intervention was related to improvements in both adherence to NIV (F(304) = 19.054, p < .001) and quality of life (F(156) = 10.264, p = .002) after eight meetings from baseline compared with the control group. Results indicated a significant change in the quality of life also over time (F(71.480) = 8.114, p = .006).

CONCLUSIONS

The findings suggest that the psychological intervention is an appropriate treatment for acceptance of and adherence to NIV in COPD in clinical practice and highlight the importance of determining the underlying reasons for NIV use.Trial Registration:ClinicalTrials.gov identifier NCT02499653.

Evidence-Based Medicine in Otolaryngology, Part XIII: Health Disparities Research and Advancing Health Equity

OBJECTIVE

To provide a contemporary resource for clinicians and researchers on health equity research and implementation strategies to mitigate or eliminate disparities in health care.

DATA SOURCES

Published studies and literature on health disparities, applicable research methodologies, and social determinants of health in otolaryngology.

REVIEW METHODS

Literature through October 2021 was reviewed, including consensus statements, guidelines, and scientific publications related to health care equity research. This research focus provides insights into existing disparities, why they occur, and the outcomes of interventions designed to resolve them. Progress toward equity requires intentionality in implementing quality improvement initiatives, tracking data, and fostering culturally competent care. Priority areas include improving access, removing barriers to care, and ensuring appropriate and effective treatment. Although research into health care disparities has advanced significantly in recent years, persistent knowledge gaps remain. Applying the lens of equity to data science can promote evidence-based practices and optimal strategies to reduce health inequities.

CONCLUSIONS

Health disparities research has a critical role in advancing equity in otolaryngology-head and neck surgery. The phases of disparities research include detection, understanding, and reduction of disparities. A multilevel approach is necessary for understanding disparities, and health equity extensions can improve the rigor of evidence-based data synthesis. Finally, applying an equity lens is essential when designing and evaluating health care interventions, to minimize bias.

IMPLICATIONS FOR PRACTICE

Understanding the data and practices related to disparities research may help promote an evidence-based approach to care of individual patients and populations, with the potential to eventually surmount the negative effects of health care disparities.

Health Literacy and Health Outcomes in Chronic Obstructive Pulmonary Disease Patients: An Explorative Study

Aim

This study aimed to evaluate the relationship between health literacy (HL) and chronic obstructive pulmonary disease (COPD) severity.

Methods

Pulmonary function test, sociodemographic features, Modified Medical Research Council (mMRC) dyspnea scale, COPD assessment test (CAT), and the European Health Literacy Survey Questionnaire were used. The study examined 13,760 patients who underwent a pulmonary function test. Out of 13,760 patients, 673 patients had FEV1/FVC values less than 70%. Those with FEV1/FVC< 0.70 (n = 336) after the reversibility test were included in the study.

Results

There was a significant decrease in HL and an increase in COPD severity (p < 0.001). In multivariate analysis, the risk of severe COPD was 2.74 times higher in patients in the poor income level than in patients in the good income level. In patients with inadequate HL, the risk of developing severe COPD was 1.80 times higher. A significant difference was found in HL index scores among the groups in terms of education level and income level (p < 0.001; p < 0.001, respectively). The most difficult topics for patients with COPD were periodic health examinations, good practices in mental health, and adult vaccinations.

Conclusions

Patients with COPD were found to be at a HL level well below the expected level. The risk of severe COPD increased with poor income and inadequate HL. Healthcare providers should be careful in accessing, understanding, and interpreting the health information of patients with inadequate HL. Therefore, patient education should be prioritized in the follow-up and in the treatment of patients with COPD. Physicians should pay maximum attention to patients with COPD in the regular use of drugs, their proper use, in taking preventive measures, and in adult vaccination.

Effectiveness of health literacy- and patient activation-targeted interventions on chronic disease self-management outcomes in outpatient settings: a systematic review

Chronic diseases are the leading causes of morbidity and mortality and account for approximately 60% of all deaths worldwide. Self-management is a key strategy to manage chronic diseases, and there is emerging evidence recommending targeting both health literacy (HL) and patient activation (PA) to improve chronic disease self-management outcomes. The aim of this systematic review is to summarise the current evidence on the impact of HL- and PA-led interventions on self-management outcomes using randomised control trials (RCTs). Six well known databases (MEDLINE, Web of Science, Scopus, Science Citation Index, EMBASE and Academic Search Complete) were searched for RCTs of chronic disease self-management interventions targeting both HL and PA and published between 2004 and June 2021. The search terms included chronic disease, self-management, patient activation/engagement and health literacy/education. Ten studies were eligible for inclusion. We found that patients with low HL and PA levels are most likely to benefit from the interventions. The moderate improvements in PA and HL in the reviewed studies were translated into some improvements in physical activity and mental health outcomes but failed to improve patients' quality of life and healthcare utilisation outcomes. Patients with low HL were more likely to have higher PA levels after the interventions. This review suggests that both HL and PA are essential pillars for improving chronic disease self-management outcomes. However, more studies are needed to explore the long-term impacts of a combination of HL and PA on chronic disease self-management outcomes.

[Knowledge Structure of Chronic Obstructive Pulmonary Disease Health Information on Health-Related Websites and Patients' Needs in the Literature Using Text Network Analysis]

PURPOSE

The purpose of this study was to identify the knowledge structure of health information (HI) for chronic obstructive pulmonary disease (COPD).

METHODS

Keywords or meaningful morphemes from HI presented on five health-related websites (HRWs) of one national HI institute and four hospitals, as well as HI needs among patients presented in nine literature, were reviewed, refined, and analyzed using text network analysis and their co-occurrence matrix was generated. Two networks of 61 and 35 keywords, respectively, were analyzed for degree, closeness, and betweenness centrality, as well as betweenness community analysis.

RESULTS

The most common keywords pertaining to HI on HRWs were lung, inhaler, smoking, dyspnea, and infection, focusing COPD treatment. In contrast, HI needs among patients were lung, medication, support, symptom, and smoking cessation, expanding to disease management. Two common sub-topic groups in HI on HRWs were COPD overview and medication administration, whereas three common sub-topic groups in HI needs among patients in the literature were COPD overview, self-management, and emotional management.

CONCLUSION

The knowledge structure of HI on HRWs is medically oriented, while patients need supportive information. Thus, the support system for self-management and emotional management on HRWs must be informed according to the structure of patients' needs for HI. Healthcare providers should consider presenting COPD patient-centered information on HRWs.

eHealth Literacy and Beliefs About Medicines Among Taiwanese College Students: Cross-sectional Study

Background

Good eHealth literacy and correct beliefs about medicines are beneficial for making good health care decisions and may further influence an individual's quality of life. However, few studies have discussed these two factors simultaneously. Moreover, gender differences are associated with health literacy and beliefs about medicines. Therefore, it is important to examine the multiple relationships between college students’ eHealth literacy and beliefs about medicines, as well as gender differences.

Objective

This study aims to (1) examine the multiple relationships between eHealth literacy and beliefs about medicines and (2) analyze gender differences in eHealth literacy and beliefs about medicines with Taiwanese college students.

Methods

We used a paper-and-pencil questionnaire that included age, gender, 3-level eHealth literacy, and beliefs about medicines to collect data. In total, 475 data points were obtained and analyzed through independent t tests and canonical correlation analyses.

Results

The t test (t₄₇₃=3.73; P<.001; t₄₇₃=–2.10; P=.04) showed that women had lower functional eHealth literacy and more specific concerns about medicines than men. Canonical correlation analyses indicated that the first and second canonical correlation coefficients between eHealth literacy and beliefs about medicines reached a significant level, implying that a multivariate relationship indeed existed.

Conclusions

These findings reveal that women in Taiwan have lower functional eHealth literacy and stronger concerns about medicines than men. In addition, students with higher eHealth literacy have more positive perceptions of and beliefs about medicines.

Patient's awareness on COPD is the strongest predictor of persistence and adherence in treatment-naïve patients in real life: a prospective cohort study

BACKGROUND

There is little evidence about the factors that predict persistence/adherence in treatment-naïve patients with COPD in clinical practice. The aim of this study was to evaluate persistence and adherence levels among treatment-naïve patients diagnosed with COPD who had a prescribed inhaled medication, using data from real-world clinical practice.

METHODS

Multicentric study with a 6 month-followed-up period. Patients were considered persistent if they collected all their inhaler refills. In a random sample of patients, we evaluated adherence using the Test of Adherence to Inhalers (TAI). We assessed Health Related Quality of Life (HRQL) with St George's Respiratory Questionnaire (SGRQ).

RESULTS

Of the 114 patients included, 46 (40.4%) were defined as persistent. Patients who had awareness about COPD (adjusted RR 2.672, 95% CI 1.125-6.349) were more likely to be persistent; patients with multidose DPI were less likely to be persistent that those with single dose DPI (adjusted RR 0.341, 95% CI 0.133-0.877). Higher levels of SGRQ total were associated with a lower probability of persistence (adjusted RR 0.945, 95%CI 0.894-0.998). Patients who had had an appointment with their GP in the previous six months were more likely to be persistent (adjusted RR 3.107, 95% CI 1.022-9.466). Patients who had awareness about COPD and those with lower symptom SGQR score were more likely to be adherent (24/25, 96.0% vs 16/22, 72.7%, p = 0.025, and mean 29.1, sd 19.4 vs mean 41.4, sd 15.9, respectively, p = 0.026, respectively).

CONCLUSIONS

Less than 50% of patients were defined as persistent. Patients' awareness of their disease and levels of HRQL were associated with high rate of persistence and adherence. In addition, frequent visits to general practitioner, increases the rate of persistence to treatment.

Protocol for a feasibility randomized trial of self-management support for people with chronic obstructive pulmonary disease using lay health coaches

Challenges with self-management are a major contributor to poor outcomes among adults with chronic obstructive pulmonary disease (COPD). The causes of poor self-management in COPD are manifold, and they arise from physical, cognitive, socioeconomic, environmental and societal sources. To address this complexity, we developed the Supporting self-Management Behaviors in Adults with COPD (SaMBA-COPD) model, which uses lay health coaches to identify a patient's barriers to effective COPD self-management and provide tailored support to help them overcome those barriers, reduce their symptoms and need for urgent care and improve their quality of life. The 6-month intervention includes referral of patients to a pharmacist for prescription of antibiotic and oral steroid "rescue packs" and support for a structured home exercise routine. All interactions of coaches and patients will take place by telephone or video call. We will test the feasibility and preliminary efficacy of SaMBA-COPD in a trial of 58 patients randomized 1:1 to the intervention or a COPD education control. Outcomes will be assessed at 6 and 9 months. Data from the trial will be used to inform the design of a fully powered, multi-site randomized trial of the intervention.

Does Health Literacy Reinforce Disease Knowledge Gain? A Prospective Observational Study of Hungarian COPD Patients

We set out to measure the health literacy (HL) of COPD patients using the Short Test of Functional Health Literacy (S-TOFHLA), perception-based screening questions (BHLS), and a specific disease knowledge test (COPD-Q). Our main focus is the relationship between functional HL and patients' disease-knowledge, which contributes to the clarification of the relationship between the different kinds of HL. In two prospective observational studies, 151 COPD patients (80 males, mean age: 62 ± 9 years) completed a questionnaire containing HL measurements, psychological tests (e.g., the Self-Control and Self-Management Scale), and questions regarding subjective health status. Medical data of the patients from the MedSole system were added. The HL scores of the COPD patients were compared to a representative sample using a t-test. Furthermore, correlations of HL with demographic, psychological, and medical variables were calculated within the patient group. The relations among the different HL measurements were tested by chi-square trials. COPD patients had significantly lower HL, as measured by S-TOFHLA. Younger and higher educated patients possessed higher S-TOFHLA scores. Unlike the demographic variables, general self-management showed significant correlations with both BHLS and with COPD-Q. Out of the medical variables, objective health status was associated with BHLS and COPD-Q. Neither BHLS nor S-TOFHLA had a correlation with COPD-Q, but they correlated with each other. We found S-TOFHLA to be a better tool in the medical context. There is a clear gap between self-perceived/functional HL and the necessary disease knowledge. Rehabilitation care for patients with lower HL was more advantageous.

Development and validation of the scoliosis misconception scale (SMS) for assessing level of misconception of patients with adolescent idiopathic scoliosis

BACKGROUND

Little is known about patients' understanding of adolescent idiopathic scoliosis (AIS). This paper aims to develop and validate the Scoliosis Misconception Scale (SMS) and to explore patients' level of misconception about AIS.

METHODS

A total of 195 patients who were newly referred with newly diagnosed AIS were recruited to assess their levels of misconception and psychological distress before and after their first consultation with a specialist. The 17-item SMS was administered to assess patients' level of misconception about AIS and the Kessler Psychological Distress Scale (K10) was used to measure their level of distress.

RESULTS

According to the Item Response Theory, all items were within the acceptable range from -3.69 to 2.39 for difficulty parameters, which determined the difficulty of the scale, while most of the items were within the acceptable range from 0.11 to 1.54 for the discrimination parameters, which determined the rate at which the probability of endorsing a correct item changes given ability levels. Internal consistency by marginal reliability was 0.66. One-sample t test revealed that participants on average scored 6.79 (SD = 2.12) before the first clinic session and 6.45 (SD = 2.51) after the first clinic session, both significantly higher than 0 [t(75) = 27.86, p < .001; t(75) = 22.43, p < .001].

CONCLUSIONS

Despite a longstanding clinical model that functions well to treat AIS, most patients still have significant misconceptions about the condition. This highlights the necessity to assess patients' knowledge level of a medical condition and potential generalisability of misconception-distress link to the forefront across other illnesses.

A structural equation model of relationships of health literacy, illness and medication beliefs with medication adherence among patients with chronic obstructive pulmonary disease

OBJECTIVE

To determine the relative contributions of health literacy (HL) and illness and medication beliefs to medication adherence among older COPD patients and determine the pathways through which they operate.

METHODS

The study was conducted using data from a prospective cohort of COPD patients in New York City and Chicago. We used structural equation modeling to examine the pathways linking HL, through medications and illness beliefs, with COPD medication adherence.

RESULTS

Out of 393 older adults with COPD, 123 (31%) had limited HL and 208 (53%) reported low adherence to daily COPD medications. Those with limited HL were more likely to have low medication adherence (p < 0.0001). Medications concerns (p = 0.001) and medication necessity (p = 0.003) demonstrated a mediational role between HL and adherence. However, in the final multivariate model, HL did not have direct effect on medication adherence (p = 0.12) and illness beliefs (p = 0.16) did not demonstrate a mediational role between HL and adherence.

CONCLUSION

Our findings suggest that low HL is not a direct predictor of poor medication adherence among COPD patients.

PRACTICE IMPLICATIONS

Addressing medication concerns and reinforcing the need for daily COPD medications may be a more effective strategy for increasing adherence in this population.

Experiences and Factors Affecting Usage of an eHealth Tool for Self-Management Among People With Chronic Obstructive Pulmonary Disease: Qualitative Study

Background

Self-management strategies are regarded as highly prioritized in chronic obstructive pulmonary disease (COPD) treatment guidelines. However, individual and structural barriers lead to a staggering amount of people with COPD that are not offered support for such strategies, and new approaches are urgently needed to circumvent these barriers. A promising way of delivering health services such as support for self-management strategies is the use of eHealth tools. However, there is a lack of knowledge about the usage of, and factors affecting the use of, eHealth tools over time in people with COPD.

Objective

This study aimed, among people with COPD, to explore and describe the experiences of an eHealth tool over time and factors that might affect usage.

Methods

The eHealth tool included information on evidence-based self-management treatment for people with COPD, including texts, pictures, videos as well as interactive components such as a step registration function with automatized feedback. In addition to the latter, automated notifications of new content and pedometers were used as triggers to increase usage. After having access to the tool for 3 months, 16 individuals (12 women) with COPD were individually interviewed. At 12 months’ access to the tool, 7 (5 women) of the previous 16 individuals accepted a second individual interview. Data were analyzed using qualitative content analysis. User frequency was considered in the analysis, and participants were divided into users and nonusers/seldom users depending on the number of logins and minutes of usage per month.

Results

Three main categories, namely, ambiguous impact, basic conditions for usage, and approaching capability emerged from the analysis, which, together with their subcategories, reflect the participants’ experiences of using the eHealth tool. Nonusers/seldom users (median 1.5 logins and 1.78 minutes spent on the site per month) reported low motivation, a higher need for technical support, a negative view about the disease and self-management, and had problematic health literacy as measured by the Communicative and Critical Health Literacy Scale (median [range] 154 [5-2102]). Users (median 10 logins and 43 minutes per month) felt comfortable with information technology (IT) tools, had a positive view on triggers, and had sufficient health literacy (median [range] 5 [5-1400]). Benefits including behavior changes were mainly expressed after 12 months had passed and mainly among users.

Conclusions

Findings of this study indicate that the level of motivation, comfortability with IT tools, and the level of health literacy seem to affect usage of an eHealth tool over time. Besides, regarding behavioral changes, gaining benefits from the eHealth tool seems reserved for the users and specifically after 12 months, thus suggesting that eHealth tools can be suitable media for supporting COPD-specific self-management skills, although not for everyone or at all times. These novel findings are of importance when designing new eHealth tools as well as when deciding on whether or not an eHealth tool might be appropriate to use if the goal is to support self-management among people with COPD.

Identifying Behavioral Phenotypes in Chronic Illness: Self-Management of COPD and Comorbid Hypertension

OBJECTIVES

To identify and characterize the constellation, or clusters, of self-management behaviors in patients with chronic obstructive pulmonary disease (COPD) and comorbid hypertension.

METHODS

Cluster analysis (n = 204) was performed with standardized scores for medication adherence to COPD and hypertension medications, inhaler technique, and diet as well as self-reported information on physical activity, appointment keeping, smoking status, and yearly influenza vaccination for a total of eight variables. Classification and regression tree analysis (CART) was performed to further characterize the resulting clusters.

RESULTS

Patients were divided into three clusters based on eight self-management behaviors, which included 95 patients in cluster 1, 42 in cluster 2, and 67 in cluster 3. All behaviors except for inhaler technique differed significantly among the three clusters (P's<0.005). CART indicated physical activity was the first differentiating variable.

CONCLUSIONS

Patients with COPD and hypertensioncan be separated into those with adequate and inadequate adherence. The group with inadequate adherence can further be divided into those with poor adherence to medical behaviors compared to those with poor adherence to lifestyle behaviors.

PRACTICE IMPLICATIONS

Once validated in other populations, the identification of patient clusters using patient self-management behaviors could be used to inform interventions for patients with multimorbidity.

The impact of health literacy on beliefs about medication in a Dutch medication-using population

PURPOSE

Medication beliefs are likely contingent on aspects of health literacy: knowledge, motivation, and competences to access, understand, appraise, and apply health information. An association between medication beliefs and health literacy is expected as they both influence self-management. The aim of this study was to examine the association between health literacy and the beliefs about overuse and harmful effects of medication and to examine modifying effects of age, gender, and number of medications on this association.

METHODS

The data were collected using the online "Medication panel" of the Dutch Institute for Rational Use of Medicine. A linear regression model was used to examine the association between health literacy and beliefs about medication and the modifying effects of age, gender, and number of medications on this association.

RESULTS

Respondents with a lower level of health literacy had more concerns about overuse (β adj.= -.174, p<.001) and harmful (β adj.= -.189, p<.001) effects of medication. This study found no modifying effects.

CONCLUSIONS

A lower health literacy level is associated with more concerns about the overuse and harmful effects of medication. The results of this study suggest that extra attention should be given to persons with low health literacy level by healthcare professionals, to decrease their concerns about overuse and harmful effects, and improve adherence to self-management behavior.

Illness perception in patients with chronic kidney disease and kidney failure: a scoping review protocol

INTRODUCTION

Patient education is a crucial component in the management of chronic kidney disease (CKD); however, many education programmes do not tailor to patients' disease-related belief and emotional reactions. According to Leventhal's self-regulation model, such beliefs and reactions, known as illness perceptions, are a part of patients' understanding of their disease and treatment-related actions. The existing research of illness perception in the field of nephrology has been heterogenous in terms of study outcomes and in study population; and the evidence of how illness perceptions affect behavioural and decisional outcomes is limited. This scoping review aims to map and summarise the evidence of published literature on illness perception among patients with CKD not yet treated by dialysis and kidney failure.

METHODS AND ANALYSIS

This study bases its approach on Joanna Brigg's Institute Guidelines on scoping review methods. The search strategy was developed together with a medical information specialist. Searches will be performed on acceptance of publication in the following databases: PubMed, EMBASE, PsycINFO via Ovid, Scopus and the Cumulative Index to Nursing and Allied Health Literature. Searches will be run without incorporating a date restriction in order to capture content from the databases' inception to present day. Search terms including 'illness perception', 'kidney disease' and 'kidney failure' will be screened in titles and abstracts. Two independent researchers will screen the abstracts and full text for full eligibility. We will include studies focusing on illness perception of patients with CKD with estimated glomerular filtration rate <60 mL/min/1.73 m2, kidney failure or recipients of kidney transplant. We will exclude patients <18 years of age, patients with acute kidney injury and non-English articles. All demographic data, study design and study findings will be collected and analysed using a data abstraction tool.

ETHICS AND DISSEMINATION

This study does not require internal review board approval. We will present the findings of this scoping review in a peer-reviewed journal.

Health literacy of people living with HIV in a rural area in Indonesia: A cross-sectional study

Indonesia, the fourth most populated country in the world, has experienced a fivefold increase in Human Immunodeficiency Virus (HIV)-infected individuals since 2001. Little is known about health literacy in people living with HIV (PLHIV) in Indonesia. This study aimed to determine the level of health literacy among PLHIV in Indonesia and assess associations between sociodemographic variables, beliefs about medicines, stigma and health literacy. We conducted a cross-sectional study using questionnaires in PLHIV in Papua, Indonesia. The short version of the Test of Functional Health Literacy in Adults (S-TOFHLA), Beliefs about Medicines Questionnaire (BMQ) and HIV stigma scale as well as questions on demographic information were completed by the participants from two hospitals in Papua, Indonesia. In a multivariate logistic regression analysis, we assessed the association between sociodemographic variables, stigma, beliefs about medicine and low health literacy. Overall, 331 participants were included, 62.0% female, 67.0% Papuans. A total of 38.5% of participants had low health literacy. PLHIV with multi-dose regimen were less likely to have low health literacy than those taking a fixed-dose combination (OR = 0.51; 95%CI = 0.32-0.82). PLHIV who had social support in medicine-taking were more likely to have low health literacy (OR = 1.78; 95%CI = 1.07-2.97). More awareness about medication overuse (OR = 1.17; 95%CI = 1.06-1.29) and medication harm (OR = 1.10; 95%CI = 1.01-1.20) were also associated with having low health literacy. Overall, interventions targeting health literacy may be a promising strategy to improve self-management.

Impact of patients' perception of COPD and treatment on adherence and health-related quality of life in real-world: Study in 53 community pharmacies

BACKGROUND

Patient adherence to treatment in chronic obstructive pulmonary disease (COPD) is essential to optimize disease management. We aimed to assess the impact of patients' perception of their treatment and disease on adherence and Health-Related Quality of Life (HRQL) in patients attending a community pharmacy, where usually subjects have a better condition than those in clinical settings.

METHODS

We performed a cross-sectional study of 318 patients with COPD in treatment with inhalers in the last 3 months from 53 community pharmacies. We assessed HRQL with St George's Respiratory Questionnaire (SGRQ). Persistence was assessed from the three previous refills and adherence through the Test of Adherence to Inhalers test.

RESULTS

Persistence was achieved by 78.6% of the patients and 58.5% had good adherence. Patients having a multidose DPI and those with MDI showed a 2.8-fold and 4.1-fold increased association, respectively, with intermediate/poor adherence in comparison with those having a single dose DPI. Those patients who did not have knowledge about COPD (aOR 2.106, p = 0.006) and those who thought that the inhaler effectiveness was fair/poor (aOR 2.361, p = 0.006) were more likely to have intermediate/poor adherence. Overall SGRQ score was significantly worse in patients with intermediate/poor adherence (p = 0.036) and in those who thought the inhaler's effectiveness was fair/poor (p < 0.001).

CONCLUSIONS

The type of inhaler and patients' knowledge and perceptions of their disease and treatment were associated with good adherence and higher HRQL. Clinicians should promote shared-decision making in the choice of inhaler depending on patients' individual abilities and beliefs.

Effect of an Educational Program on Healthcare Professionals' Readiness to Support Patients with Asthma, Allergies, and Chronic Obstructive Lung Disease for Improved Medication Adherence

PURPOSE

The aim of this study was to strengthen the healthcare professionals' readiness to support patients who have asthma, an allergy, and COPD for better medication adherence.

METHODS

The design was an educational intervention in a study population (n = 70) consisting of 66 nurses and four other allied healthcare professionals working in primary care with patients diagnosed with asthma, allergy, or COPD in a county in southern Sweden. As part of two training days, an educational intervention-consisting of lectures and workshops-was conducted. Both qualitative and quantitative data were collected. The qualitative data were collected during the workshops when the participants worked with fictitious patient cases. They documented in writing how they, based on the theoretical content in the educational intervention in combination with their clinical experiences, reasoned that the fictitious patients could be supported for better adherence. This documentation constituted qualitative data. The quantitative data were collected through questionnaires, which the participants completed before and after the intervention. Data from the questionnaires were statistically analyzed using descriptive statistics and paired t-tests. The qualitative data collected from the workshops were analyzed with content analysis.

RESULTS

The intervention increased the participants' knowledge of adherence (pre mean 3.95 versus post mean 4.18, p=0.001) and how to better support patients' adherence to medication (pre mean 3.71 versus post mean 3.98, p=0.001). Moreover, their knowledge of how to measure patients' adherence behavior (pre mean 3.02 versus post mean 3.54, p=0.001) and how to communicate with patients effectively about adherence was heightened (pre mean 3.92 versus post mean 4.13, p=0.011). Furthermore, participants felt that their readiness to support patients for better adherence had strengthened (pre mean 3.78 versus post mean 4.13, p=0.001). Individual adherence support for three fictitious patients with different adherence issues was developed.

CONCLUSION

An educational intervention focusing on adherence and communication equipped healthcare professionals with tools to support patients with asthma, an allergy, or COPD for better medication adherence.

Health Literacy and Medication Adherence in COPD Patients: When Caregiver Presence Is Not Sufficient

Limited health literacy (HL) is associated with a lower medication adherence in patients with chronic obstructive pulmonary disease (COPD). In this study, we examined the potential mitigating role of caregiver support on the relationship between HL and adherence to COPD medications. We conducted a prospective observational study of adults with COPD and their caregivers. HL was assessed using the Short Test of Functional Health Literacy in Adults (S-TOFHLA) and COPD medication adherence was evaluated with the Medication Adherence Rating Scale (MARS). We also collected caregiver HL data for a subset of participants. We tested whether having a caregiver impacted the relationship between HL and medication adherence using cross-sectional data collected between 2011 and 2015. Our sample included 388 COPD patients and 97 caregivers. COPD patients with low HL had a lower medication adherence (odds ratio [OR]: 0.44, 95% confidence interval [CI]: 0.24-0.81) after adjusting for sociodemographic factors. Caregiver presence was not associated with increased patient medication adherence (OR: 1.28, 95% CI: 0.79-2.08). Among the subset of patients with caregivers, low patient HL remained associated with a lower medication adherence (OR: 0.28, 95% CI: 0.09-0.82) when adjusted for caregiver HL and sociodemographic factors. Low HL is associated with lower COPD medication adherence, and this effect is not mitigated by the presence of a caregiver. These findings suggest a need for effective strategies to manage high-risk COPD patients with low HL, even among those with adequate support from caregivers, and to design interventions for both patients and caregivers with low HL.

The Acceptance of Key Public Health Interventions by the Polish Population Is Related to Health Literacy, But Not eHealth Literacy

Background: Public health and health promotion rely on many different interventions, which range from health education and communication, through community mobilisation and changes to environmental conditions, to legal and fiscal actions. The introduction of the increased tax on sugar-sweetened beverages (SSB), popularly called sugar tax (ST), and a mandatory programme of vaccinations are the strategies inciting the most vivid discussions in Polish society. The study was intended to assess the determinants of the attitudes of Polish society regarding the ST and to vaccinations. Methods: For the analysis, the data originating from the survey of a representative adult sample of Polish society (n = 1000) was used. The survey was based on computer-assisted telephone interviewing (CATI). The assessment of the relationships between the selected variables and the opinions about the introduction of the ST and the safety and effectiveness of vaccinations were carried out using the chi² test and univariate logistic regression models. Results: The acceptance of the ST and vaccination showed a significant relationship to the level of health literacy (HL) but not to eHealth literacy (eHL). Respondents having a higher rather than lower HL; older rather than younger; married rather than singles; retired, or on a disability pension, rather than vocationally active and nonusers of the Internet rather than users were more likely to show an acceptance for both interventions. Those more frequently using health care services and those with chronic diseases showed a greater belief in the safety and effectiveness of vaccinations. Conclusions: The relationship between the opinions of the two public health interventions analysed and the sociodemographic variables demonstrated similar patterns. Interestingly, the opinions were associated only with HL and not with eHL and users of the Internet were more sceptical about the interventions.

Partnering with parents to improve outcomes for substance exposed newborns-a pilot program

OBJECTIVE

Assess impact of parental involvement in care provision for term substance exposed newborns (SENs).

STUDY DESIGN

Prospective observational cohort study included mothers with opioid use disorder and their SENs over 4 year study period. Maternal-Infant dyads enrolled in EMPOWER and rooming-in (RI) programs were included and received care 24/7 in a private room until newborn's discharge. Outcomes were compared for dyads participating in EMPOWER/RI with historical controls.

RESULTS

Ninety of 156 historical SENs were RI eligible, while 49 of 108 SENs born during RI period had mothers enrolled in EMPOWER. EMPOWER/RI SENs had lower rates for and duration of pharmacotherapy, shorter neonatal intensive care unit (NICU) and hospital lengths of stay. EMPOWER/RI increased initiation and continuation of breastfeeding at discharge.

CONCLUSIONS

Parental participation was associated with a decrease in initiation and duration of pharmacotherapy, NICU admission, length of stay and hospital charges while increasing breastfeeding initiation and continuation at discharge.

Asthma and COPD patients' perceived link between health literacy core domains and self-management of their condition

OBJECTIVE

Health literacy (HL) is a person's ability to practically apply a wide range of cognitive and non-cognitive skills, to make health-related decisions. Currently, no tool applies all HL core domains to capture necessary data to measures HL in adult asthma and COPD patients. We endeavored to develop a comprehensive, function-based tool that adequately and accurately measures HL skills of this patient population. We explored the perspectives of patients related to each core HL domain, with an emphasis on self-management practices.

METHODS

Sixteen focus groups were conducted (n = 93; 40 asthma and 53 COPD) across Canada. Data was analyzed using NVivo12.

RESULTS

Thirteen subthemes were identified within five HL domains: (a) access: active access; passive access; lack of access; (b) understanding: how to improve understanding; (c) trustworthiness; relevancy and validity of information: pre- and post- application of information; (d) communication: barriers to proper communication; (e) application of information: making health decisions.

CONCLUSIONS

Participants provided valuable insight in terms of disease management topics and corresponding items to include in our HL tool.

PRACTICE IMPLICATIONS

Involvement of patients from initial stage allowed us to develop a tool that will serve as a first ever developed HL tool for asthma and COPD patient group.

Levels and determinants of health literacy and patient activation among multi-morbid COPD people in rural Nepal: Findings from a cross-sectional study

BACKGROUND

Health literacy (HL) and patient activation (PA) are necessary foundations to engage patients in self-management intervention. Each concept plays a unique role in improving access to the effective self-management of chronic disease. In this cross-sectional study, we examined the levels and determinants of HL and PA among the multi-morbid COPD patients in Nepal.

METHODS

We conducted interviews with a simple random sample of 238 multi-morbid COPD people from July 2018 to January 2019. The questionnaire included sociodemographic profiles, five domains of the Health Literacy Questionnaire (HLQ), 13-item Patient Activation Measure (PAM) and patient's illness perception by Brief Illness Perception Questionnaire (BIPQ). Multivariable logistic regression was used to examine the associations.

RESULTS

Most people with COPD had low health levels across each of the five domains of the HLQ. The proportion of people with low literacy level across each of the domains was: (i) feeling understood and supported by healthcare providers (79.0%), (ii) having sufficient information to manage my own health (76.5%), (iii) social support for health (77.3%), (iv) ability to find the good health information (75.2%), and (v) understand the health information well enough to know what to do (74.8%), respectively. The majority of patients also reported low levels of patient activation (level 1: 81.5%; level 2: 11.8%), with only 6.7% (level 3: 5%; level 4: 1.7%) reported higher patient activation level. We found significant associations between poor HL levels in the HLQ domains and having no education, being female or from Indigenous and Dalits communities, and having a monthly family income of less than USD176. Having no education and poor illness perception were significantly associated with poor activation level on PAM scale.

CONCLUSION

A high proportion of multi-morbid COPD peoples had low levels of HL and were less activated than what would be required to self-manage COPD. These were in turn associated with socioeconomic factors and poor illness perception. The findings from this study are being used to design a COPD self-management program tailored to the low health literate population.

An Electronic Medication Module to Improve Health Literacy in Patients With Type 2 Diabetes Mellitus: Pilot Randomized Controlled Trial

Background

In primary care, patients play a crucial role in managing care processes and handling drug treatment. A decisive factor for success is their health literacy, and several interventions have been introduced to support patients in fulfilling their responsibility.

Objective

The aim of this study is to assess the influence of such an intervention (ie, a medication module) within a patient-led electronic health record on patients’ health literacy.

Methods

We conducted a randomized controlled study among community-dwelling patients with type 2 diabetes mellitus. Patients were recruited from primary care practices. After randomization, patients either had access to an internet-based medication module allowing them to store their medication information, look up drug information, and print a medication schedule (intervention group), or they received an information brochure on the importance of medication schedules (control group). After 4-8 weeks, all patients were invited to attend a structured medication review (ie, follow-up visit). Data were collected via questionnaires before the start of the intervention and during the follow-up visit. The main outcome measure was the mean difference in health literacy between baseline and follow-up assessments of patients in the control and intervention groups.

Results

Of 116 recruited patients, 107 (92.2%) completed the follow-up assessment and were eligible for intention-to-treat analyses. Only 73 patients, of which 29 were in the intervention group, followed the study protocol and were eligible for per-protocol analysis. No differences in overall health literacy were observed in either the intention-to-treat or in the per-protocol cohorts. Reasons for a null effect might be that the cohort was not particularly enriched with participants with low health literacy, thus precluding measurable improvement (ie, ceiling effect). Moreover, the success of implementation was considered poor because both the correct application of the study procedure (ie, randomization according to the protocol and dropout of 29 patients) and the actual interaction with the medication module was modest (ie, dropout of 9 patients).

Conclusions

The conduct of this randomized controlled study was challenging, leaving it open whether inadequate implementation, too short of a duration, or insufficient efficacy of the intervention, as such, contributed to the null effect of this study. This clearly outlines the value of piloting complex interventions and the accompanying process evaluations.

Patient factors associated with diabetes medication adherence at different health literacy levels: a cross-sectional study at a family medicine clinic

BACKGROUND

Type 2 diabetes (T2D) incurs tremendous health costs associated with various complications due to poor diabetes control. Medication adherence, which is correlated with patients' health literacy, should be consistently practiced achieving optimal diabetes control. A deeper understanding of the specific communication and psychosocial factors related to medication-taking behaviors across different levels of health literacy among people with T2D will guide the development of effective interventions and strategies to enhance medication adherence.

OBJECTIVES

This cross-sectional study aimed to identify salient patient factors associated with diabetes medication adherence across different levels of health literacy.

METHODS

A questionnaire was administered via a face-to-face approach with 205 participants at a family medicine clinic. Study participants were all above 20 years of age with T2D, were prescribed at least one oral diabetes medication, and understood English. The questionnaire assessed participants' health literacy, self-efficacy for medication use, beliefs in medicines, patient-provider communication, perceived barriers to medication adherence, and self-reported medication adherence. Separate analysis of covariance was used to compare the mean scores of patient factors related to medication adherence across people with different health literacy levels.

RESULTS

The mean age of participants was 61 years old, and the majority of the participants were female (57%), White (75%), and college educated (62%). Thirty-three percent of the participants had adequate health literacy, but only 43% of them reported high adherence to their diabetes medications. Analysis of covariance showed that having stronger self-efficacy (P < 0.001), lower concern beliefs about medication (P = 0.047), and fewer perceived barriers to medication-taking (P < 0.001), are necessary for better medication adherence.

CONCLUSION

Findings suggest that practitioners should address concern beliefs among low-adherent patients with low health literacy, help improve self-efficacy, and address perceived barriers to medication adherence among all low-adherent patients to optimally support patients' diabetes care.

Facilitators and barriers to the self-management of COPD: a qualitative study from rural Nepal

OBJECTIVE

To understand the facilitators and barriers to the self-management of chronic obstructive pulmonary disease (COPD) in rural Nepal.

SETTINGS

Community and primary care centres in rural Nepal.

PARTICIPANTS

A total of 14 participants (10 people with COPD and 4 health care providers) were interviewed.

PRIMARY AND SECONDARY OUTCOME MEASURES

People with COPD and healthcare provider's experience of COPD self-management in rural Nepal.

RESULTS

Facilitators and barriers affecting COPD self-management in Nepal operated at the patient-family, community and service provider levels. People with COPD were found to have a limited understanding of COPD and medications. Some participants reported receiving inadequate family support and described poor emotional health. At the community level, widespread use of complementary and alternative treatment was found to be driven by social networks and was used instead of western medicine. There were limited quality controls in place to monitor the safe use of alternative treatment. While a number of service level factors were identified by all participants, the pertinent concerns were the levels of trust and respect between doctors and their patients. Service level factors included patients' demands for doctor time and attention, limited confidence of people with COPD in communicating confidently and openly with their doctor, limited skills and expertise of the doctors in promoting behavioural change, frustration with doctors prescribing too many medicines and the length of time to diagnose the disease. These service level factors were underpinned by resource constraints operating in rural areas. These included inadequate infrastructure and resources, limited skills of primary level providers and lack of educational materials for COPD.

CONCLUSIONS

The study findings suggest the need for a more integrated model of care with multiple strategies targeting all three levels in order to improve the self-management practices among people with COPD.

Factors Influencing Self-Management of Chronic Obstructive Pulmonary Disease by Community-Dwelling Adults

Individuals with chronic obstructive pulmonary disease (COPD) struggle with effective self-management, contributing to poor health outcomes and costly health care. More research is needed to understand the factors influencing COPD self-management better in order to improve outcomes and reduce health care costs for those living with this prevalent chronic illness. The purpose of this article is to describe factors influencing community-dwelling adults' COPD self-management. In-depth interviews were conducted with 28 people living with COPD. Braun and Clarke's thematic analysis approach was used to analyze interview data, and it resulted in the identification of themes providing insight into COPD self-management as described by those living with the disease. Specifically, factors impacting engagement in treatment recommendations are described. These findings have implications for informing evidence-based recommendations for self-management support and improving the quality of care provided to those with COPD.

Status of and strategies for improving adherence to COPD treatment

Despite the wide application of adherence as a concept, the definition, evaluation and improvement of the adherence to treatment by patients with chronic obstructive pulmonary disease (COPD) still present some challenges. First, it is necessary to clearly define the concepts of treatment adherence, compliance and persistence. Second, it is critical to consider the various methods of evaluating and quantifying adherence when interpreting adherence studies. In addition, the advantages and disadvantages of the different ways of measuring treatment adherence should be taken into account. Another subject of some debate is the number of variables associated with COPD treatment adherence. Adherence is a complex concept that goes beyond the dosage or the use of inhalation devices, and a number of variables are involved in determining adherence, from the clinical aspects of the disease to the patient's confidence in the doctor's expertise and the level of social support experienced by the patient. Notably, despite these challenges, the importance of adherence has been well established by clinical trials and routine clinical practice. The available evidence consistently shows the substantial impact that a lack of adherence has on the control of the disease and its long-term prognosis. For these reasons, the correct evaluation of therapeutic adherence should be a key objective in clinical interviews of patients. In recent years, various initiatives for improving adherence have been explored. All these initiatives have been based on patient education. Therefore, health care professionals should be aware of the issues pertaining to adherence and take the opportunity to educate patients each time they contact the health care system.

The roles of dispositional coping style and social support in helping people with respiratory disease cope with a breathlessness crisis

AIM

To explore the role of coping moderators in self-management of breathlessness crises by people with advanced respiratory disease.

DESIGN

A secondary analysis of semi-structured interview data.

METHODS

Interviews with patients who had advanced respiratory disease, chronic breathlessness and at least one experience where they considered presenting to Emergency but self-managed instead (a "near miss"). Participants were recruited from New South Wales, Queensland, Victoria, South Australia or Tasmania. Eligible caregivers were those who contributed to Emergency-related decision-making. Interviews were coded inductively and then deductively against the coping moderators social support and dispositional coping style, defined by the Transactional Model of Stress and Coping.

RESULTS

Interviews were conducted between October 2015 - April 2016 with 20 patients and three caregivers. Social networks offered emotional and practical support but also had potential for conflict with patients' 'hardy' coping style. Patient hardiness (characterized by a sense of 'commitment' and 'challenge') promoted a proactive approach to self-management but made some patients less willing to accept support. Information-seeking tendencies varied between patients and were sometimes shared with caregivers. An optimistic coping style appeared to be less equivocally beneficial.

CONCLUSION

This study shows that social support and coping style may influence how people self-manage through their breathlessness crises and identified ways coping moderators can facilitate or hinder effective self-management.

IMPACT

This study confers insights into how social-support and coping style can be supported and optimized to facilitate breathlessness self-management. Acknowledging coping moderator interactions is beneficial for developing resources and strategies that recognise patient mastery.

Association Between Health Literacy, Electronic Health Literacy, Disease-Specific Knowledge, and Health-Related Quality of Life Among Adults With Chronic Obstructive Pulmonary Disease: Cross-Sectional Study

Background

Despite the relatively high prevalence of low health literacy among individuals living with chronic obstructive pulmonary disease (COPD), limited empirical attention has been paid to the cognitive and health literacy–related skills that can uniquely influence patients’ health-related quality of life (HRQoL) outcomes.

Objective

The aim of this study was to examine how health literacy, electronic health (eHealth) literacy, and COPD knowledge are associated with both generic and lung-specific HRQoL in people living with COPD.

Methods

Adults from the COPD Foundation’s National Research Registry (n=174) completed a cross-sectional Web-based survey that assessed sociodemographic characteristics, comorbidity status, COPD knowledge, health literacy, eHealth literacy, and generic/lung-specific HRQoL. Hierarchical linear regression models were tested to examine the roles of health literacy and eHealth literacy on generic (model 1) and lung-specific (model 2) HRQoL, after accounting for socioeconomic and comorbidity covariates. Spearman rank correlations examined associations between ordinal HRQoL items and statistically significant hierarchical predictor variables.

Results

After adjusting for confounding factors, health literacy, eHealth literacy, and COPD knowledge accounted for an additional 9% of variance in generic HRQoL (total adjusted R²=21%; F_9,164=6.09, P<.001). Health literacy (b=.08, SE 0.02, 95% CI 0.04-0.12) was the only predictor positively associated with generic HRQoL (P<.001). Adding health literacy, eHealth literacy, and COPD knowledge as predictors explained an additional 7.40% of variance in lung-specific HRQoL (total adjusted R²=26.4%; F_8,161=8.59, P<.001). Following adjustment for covariates, both health literacy (b=2.63, SE 0.84, 95% CI 0.96-4.29, P<.001) and eHealth literacy (b=1.41, SE 0.67, 95% CI 0.09-2.73, P<.001) were positively associated with lung-specific HRQoL. Health literacy was positively associated with most lung-specific HRQoL indicators (ie, cough frequency, chest tightness, activity limitation at home, confidence leaving home, sleep quality, and energy level), whereas eHealth literacy was positively associated with 5 of 8 (60%) lung-specific HRQoL indicators. Upon controlling for confounders, COPD knowledge (b=−.56, SE 0.29, 95% CI −1.22 to −0.004, P<.05) was inversely associated with lung-specific HRQoL.

Conclusions

Health literacy, but not eHealth literacy, was positively associated with generic HRQoL. However, both health literacy and eHealth literacy were positively associated with lung-specific HRQoL, with higher COPD knowledge indicative of lower lung-specific HRQoL. These results confirm the importance of considering health and eHealth literacy levels when designing patient education programs for people living with COPD. Future research should explore the impact of delivering interventions aimed at improving eHealth and health literacy among patients with COPD, particularly when disease self-management goals are to enhance HRQoL.

Design and rationale of a mixed methods randomized control trial: ADdressing Health literacy, bEliefs, adheRence and self-Efficacy (ADHERE) program to improve diabetes outcomes

BACKGROUND

Improving medication adherence is one of the most effective approaches to improving the health outcomes of patients with diabetes. To date, enhancing diabetes medication adherence has occurred by improving diabetes-related knowledge. Unfortunately, behavior change often does not follow knowledge change. Enhancing communication between patients and healthcare professionals through addressing health literacy-related psychosocial attributes is critical.

OBJECTIVE

Examine whether a patient-centered intervention augmenting usual care with a health literacy-psychosocial support intervention will improve medication adherence for patients with diabetes, compared to usual care.

METHODS

This study is a randomized controlled trial with an intervention mixed methods design. Fifty participants being enrolled are English-speaking, 18-80 years old with diagnosed diabetes, take at least one diabetes medication, have low diabetes medication adherence (proportion of days covered less than 80% or based on clinical notes), and have poor diabetes control (hemoglobin A1c of ≥8%). Participants will be allocated to either a control group receiving usual care (n = 25) or an intervention group (n = 25) receiving usual care and a 6-session intervention focusing on the modifiable psychosocial factors that may influence medication adherence. A questionnaire will be administered at baseline and at the end of the intervention to all participants to assess the effectiveness of the intervention. Fifteen participants from the intervention group will be interviewed to explore participants' experiences and perceptions of the intervention processes and outcomes.

CONCLUSIONS

The trial will examine if a patient-centered intervention that addresses patients' health literacy and focuses on modifiable psychosocial factors will improve medication adherence among patients with diabetes.

Revealing Methodological Challenges in Chronic Obstructive Pulmonary Disease Studies Assessing Comorbidities: A Narrative Review

Beyond respiratory impairment, patients with chronic obstructive pulmonary disease (COPD) often suffer from comorbidities which are associated with worse health status, higher health care costs and worse prognosis. Reported prevalences of comorbidities largely differ between studies which might be explained by different assessment methods (objective assessment, self-reported assessment, or assessment by medical records), heterogeneous study populations, inappropriate control groups, incomparable methodologies, etc. This narrative review demonstrates and further evaluates the variability in prevalence of several comorbidities in patients with COPD and control individuals and discusses several shortcomings and pitfalls which need to be considered when interpreting comorbidity data. Like in other chronic organ diseases, the accurate diagnosis and integrated management of comorbidities is a key for outcome in COPD. This review highlights that there is a need to move from the starting point of an established index disease towards the concept of the development of multimorbidity in the elderly including COPD as an important and highly prevalent pulmonary component.
