Health literacy in nephrology: why is it important?

Health literacy in older adults receiving hemodialysis in Turkey: A cross-sectional study

INTRODUCTION

This study aimed to determine the health literacy level and related factors of older adults receiving hemodialysis treatment.

METHODS

A cross-sectional study was conducted at the five dialysis centers, using the information form and Turkish Health Literacy Survey-32 (THLS-32). A total of 336 older adults receiving hemodialysis treatment participated.

RESULTS

The general health literacy score was found to be 25.69 ± 14.47. Based on the health literacy assessment scores, 62.5% of the participants were in the category of inadequate and limited level of health literacy. The lower level of education, perceived health status, income, and getting help in reading and writing were statistically significant predictors of the health literacy score.

CONCLUSION

The health literacy of older adults receiving hemodialysis treatment was inadequate and limited. Findings of this study emphasize the importance of integrating health literacy assessment in clinical care settings and supporting the health literacy of older adults receiving hemodialysis treatment.

The Effect of Health Literacy on Patient Outcomes in Stage 3b-4 Pre-Dialysis Patients: A Semi-Experimental Study

This study was conducted to investigate the effect of health literacy on patient outcomes in pre-dialysis patients. A semi-experimental study. The study was conducted with 45 intervention and 45 control patients with glomerular filtration rates between 15-44ml/min/1.73m2. The adequate health literacy of the patients in the intervention group increased from 2.2% to 31.1%. Increased health literacy led to a significant decrease in systolic and diastolic blood pressure values and the severity of symptoms. The study showed that increased health literacy in pre-dialysis patients improves patient outcomes. Nursing care is needed in pre-dialysis.

Prevalence and Modifiable Factors for Holistic Non-Adherence in Renal Transplant Patients: A Cross-Sectional Study

Introduction

In renal transplant recipients, compliance with medical therapy is vital. Non-adherence is considered a risk factor for worst outcomes in kidney recipients, with attributed outcomes of 64% for graft loss and 80% for late acute rejection. Most literature defines adherence as self-based immunosuppression compliance but does not consider other relevant factors such as consult and procedure compliance. Therefore, this study aims to describe adherence prevalence in kidney transplant recipients and the factors related to non-adherence.

Methods

This cross-sectional study included 1030 renal transplant patients followed by Colombiana de Trasplantes between January 2019 and July 2021. Sociodemographic and clinical variables were obtained based on clinical records. The mental-health group diagnosed holistic adherence in a semi-structured interview. The diagnosis considered medication intake failure, frequency and number of failures to medical controls or other procedures, suspicious non-adherence behaviors, and serum levels of immunosuppressants. A bivariate followed a descriptive analysis, and a forward logistic regression was performed for non-adherence.

Results

Patients had a median of 47 years, and 58.1% were male. Non-adherence was presented in 30.7% of patients. The non-adherence patients were younger, with a higher prevalence of males, single, divided transplant care, had a longer time after transplantation, psychopathological diagnosis, and more reinforcement education by only nursing. Older age and multidisciplinary reinforcement education were protective factors. On the other hand, poor social support, psychopathology diagnosis, and longer time after transplant presented as non-adherence risk factors.

Conclusion

Holistic non-adherence was diagnosed in approximately one-third of renal transplant recipients. Its definition included more than just medication non-compliance and could identify more non-adherent patients. Notably, there is a need to consider the related factors in the health follow-up and encourage future research in modifiable factor interventions aiming to increase adherence and achieve better outcomes for renal transplant patients.

The role of low health literacy in shared treatment decision-making in patients with kidney failure

The classic paternalist medicine in nephrology has been modified to a shared decision-making model that clearly offers a benefit in patients with kidney disease. One of the cornerstones of shared treatment decision in patients with kidney failure is the understanding of kidney disease. As kidney disease is silent until advanced stages and is also an entity with a complex pathophysiology with little knowledge in the general population, its presence and understanding are difficult for most people. Health literacy (HL) plays a crucial role in the care of patients with kidney disease and the shared treatment decision. Limited HL has been associated with inefficient use of health services, non-compliance of medications, worse quality of life and increased mortality. In this review, we will address the importance of low HL in nephrology in terms of diagnosis, measurement, its effect on shared decision-making and how to increase it in people with kidney disease.

The ABCs of Kidney Disease: Knowledge Retention and Healthcare Involvement

Low health literacy in the chronic kidney disease population results in lower rates of pre-dialysis preparation and understanding of management to slow progression. The ABCs of Kidney Disease education class provided education in a more consistent manner outside of routine office visits. We aimed to study whether a structured education program would increase kidney disease-specific knowledge and healthcare involvement. Knowledge retention at least 6 months after the class assessed by the Kidney Disease Knowledge Surveys (KiKS) and healthcare involvement based on surveys sent to referring providers were found to have increased. Incorporation of a structured education program would be important for providers to improve long-term knowledge and lead to greater healthcare involvement. Providing an education class outside of the routine office visits will provide a greater impact on health literacy.

Development and application of a chronic kidney disease-specific health literacy, knowledge and disease awareness assessment tool for patients with chronic kidney disease in Taiwan

OBJECTIVES

This study aims to develop an assessment tool for health literacy and knowledge specific to chronic kidney disease (CKD) for use in examining the associations between health literacy, disease-specific knowledge and disease awareness among patients with CKD in Taiwan.

DESIGN

An assessment tool in Mandarin and Taiwanese was developed based on patient input, panel discussions with experts and a literature review, and checked for validity and reliability in a pilot test. Formal data were collected through population-based sampling with a set quota according to region and hospital accreditation level. Cross-sectional data were collected to confirm the reliability and validity of the assessment tool. Levels of health literacy, disease knowledge, and disease awareness were then reported and analysed.

SETTING

Sample hospitals included 10 medical centres, 18 regional hospitals and 15 local hospitals in Taiwan. Researchers were granted Internal Review Board approval and obtained agreement to collect data in all study settings.

PARTICIPANTS

Patients at least 20 years old who had been diagnosed with CKD of any stage were eligible to participate. The formal assessment collected 1155 valid questionnaires, yielding an 87.3% response rate. The mean age of participants was 67.48 years (SD=12.87, range 22-98), while 484 (41.95%) were female and 78% were aware they had CKD.

RESULTS

The self-devised instrument proved to have excellent reliability and validity. Use of the instrument in the main study showed that CKD-specific health literacy was significantly associated with age (β=-0.33, p<0.00), educational attainment and disease awareness (β=0.13, p<0.00). CKD-specific knowledge was also significantly associated with age (β=-0.18, p<0.00), educational attainment and disease awareness (β=0.19, p<0.00).

CONCLUSIONS

This CKD-specific health literacy and knowledge assessment tool developed for Mandarin and Taiwanese-speaking patients is reliable and well validated. Patients with CKD who are aware of and understand their disease performed better in the assessment.

Renal recipients' knowledge and self-efficacy during first year after implementing an evidence based educational intervention as routine care at the transplantation clinic

BACKGROUND

Following an implementation plan based on dynamic dialogue between researchers and clinicians, this study implemented an evidence-based patient education program (tested in an RCT) into routine care at a clinical transplant center. The aim of this study was to investigate renal recipients' knowledge and self-efficacy during first year the after the intervention was provided in an everyday life setting.

METHODS

The study has a longitudinal design. The sample consisted of 196 renal recipients. Measurement points were 5 days (baseline), 2 months (T1), 6 months (T2), and one-year post transplantation (T3). Outcome measures were post-transplant knowledge, self-efficacy, and self-perceived general health.

RESULTS

No statistically significant changes were found from baseline to T1, T2, and T3. Participants' levels of knowledge and self-efficacy were high prior to the education program and did not change throughout the first year post transplantation.

CONCLUSION

Renal recipients self-efficacy and insight in post-transplant aspects seem to be more robust when admitted to the hospital for transplantation compared to baseline observations in the RCT study. This may explain why the implemented educational intervention did not lead to the same positive increase in outcome measures as in the RCT. This study supports that replicating clinical interventions in real-life settings may provide different results compared to results from RCT's. In order to gain a complete picture of the impacts of an implemented intervention, it is vital also to evaluate results after implementing findings from RCT-studies into everyday practice.

Health literacy level in a various nephrology population from Québec: predialysis clinic, in-centre hemodialysis and home dialysis; a transversal monocentric observational study

Background

Health literacy refers to the ability of individuals to gain access to, use, and understand health information and services in order to maintain a good health. It is especially important in nephrology due to the complexity of chronic kidney disease (CKD). The present study sought to define health literacy levels in patients followed in predialysis clinic, in-center dialysis (ICHD), peritoneal dialysis (PD) and home hemodialysis (HHD).

Methods

This transversal monocentric observational study analysed 363 patients between October 2016 and April 2017. The Brief Health Literacy Screen (BHLS) and the Health Literacy Questionnaire (HLQ) were used to measure health literacy. Multivariate linear regressions were used to compare the mean scores on the BHLS and HLQ, across the four groups.

Results

Patients on PD had a significantly higher BHLS’score than patients on ICHD (p = 0.04). HLQ’s scores differed across the groups: patients on HHD (p = 0.01) and PD (p = 0.002) were more likely to feel understood by their healthcare providers. Compared to ICHD, patients on HHD were more likely to have sufficient information to manage their health (p = 0.02), and patients in the predialysis clinic were more likely to report high abilities for health information appraisal (p < 0.001).

Conclusion

In a monocentric study, there is a significant proportion of CKD patients, especially in predialysis clinic and in-centre hemodialysis, with limited health literacy. Patients on home dialysis (HHD and PD) had a higher level of health literacy compared to the other groups.

Grado de incumplimiento terapéutico en función del nivel de alfabetización en salud en pacientes en hemodiálisis

Introducción: El paciente en hemodiálisis está sometido a un régimen terapéutico cuya adherencia contribuye a disminuir la aparición de complicaciones asociadas mejorando la morbimortalidad. El incumplimiento terapéutico es un problema prevalente en la práctica clínica. Bajos niveles de alfabetización en salud se relacionan con falta de autocuidados, errores en la toma de medicaciones y dificultad para entender instrucciones, lo que trae consigo una mayor tasa de incumplimiento terapéutico. Objetivo:  Conocer el grado de incumplimiento terapéutico en función del grado de alfabetización en salud de los pacientes sometidos a hemodiálisis. Material y Método: Estudio prospectivo en 35 pacientes en programa de hemodiálisis.  La alfabetización en salud se valoró con el cuestionario Health Literacy Survey European Union y el grado de incumplimiento terapéutico mediante la ganancia de peso interdialítica e indicadores analíticos, según recomendaciones de guías clínicas. Resultados: Los pacientes con nivel de alfabetización adecuada (≥34 puntos) presentaron menor incumplimiento terapéutico que pacientes con alfabetización inadecuada en relación a ganancia de peso interdialítica (78%vs 70%), potasio (67%vs56%), albúmina (83%vs72%) pero mayor IT con el fósforo (83,33%vs51,44%) – p<0,05 en todos los casos-. Conclusiones: Los pacientes con mayor nivel de alfabetización en salud tienen un menor grado de incumplimiento terapéutico, a excepción del fósforo, que es el parámetro con peor tasa de adherencia.

Why and how should we promote home dialysis for patients with end-stage kidney disease during and after the coronavirus 2019 disease pandemic? A French perspective

The health crisis induced by the pandemic of coronavirus 2019 disease (COVID-19) has had a major impact on dialysis patients in France. The incidence of infection with acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the first wave of the COVID-19 epidemic was 3.3% among dialysis patients-13 times higher than in the general population. The corresponding mortality rate was high, reaching 21%. As of 19th April, 2021, the cumulative prevalence of SARS-CoV-2 infection in French dialysis patients was 14%. Convergent scientific data from France, Italy, the United Kingdom and Canada show that home dialysis reduces the risk of SARS-CoV-2 infection by a factor of at least two. Unfortunately, home dialysis in France is not sufficiently developed: the proportion of dialysis patients being treated at home is only 7%. The obstacles to the provision of home care for patients with end-stage kidney disease in France include (i) an unfavourable pricing policy for home haemodialysis and nurse visits for assisted peritoneal dialysis (PD), (ii) insufficient training in home dialysis for nephrologists, (iii) the small number of administrative authorizations for home dialysis programs, and (iv) a lack of structured, objective information on renal replacement therapies for patients with advanced chronic kidney disease (CKD). We propose a number of pragmatic initiatives that could be simultaneously enacted to improve the situation in three areas: (i) the provision of objective information on renal replacement therapies for patients with advanced CKD, (ii) wider authorization of home dialysis networks and (iii) price increases in favour of home dialysis procedures.

Patient-Centered Self-Management in Patients with Chronic Kidney Disease: Challenges and Implications

This review aims to identify attributes of patient-centered self-management (PCSM) in the current literature and explore its implementation in resolving patient obstacles in chronic kidney disease (CKD) treatment and management. A search of relevant articles and literature on PCSM, integrated care, and challenges of CKD management was conducted. Vital attributes of PCSM and current self-management interventions employed to resolve patient obstacles in CKD management were identified from inclusion studies. Findings affirm that PCSM strategies have positive effects on CKD management, but a lack of quality primary study, and long-term evidence presents the need for further development. Future research should focus on the development of a standardized and universal integrated PCSM model and a uniform system of data collection in the clinical setting. The difficulty of CKD management lies in how it is a comorbid and progressive disease. A pure biomedical approach is inadequate. Our review recommends that an integrated PCSM approach with health literacy and information technology intervention, which unifies and integrates patient education, can address the difficulties that are contributing to unsuccessful treatment outcomes. An integrated PCSM model should be implemented systematically and methodologically into future CKD management and health policies.

Fact-finding survey on health literacy among Japanese predialysis chronic kidney disease patients: a multi-institutional cross-sectional study

BACKGROUND

Low health literacy (HL) has been associated with poor chronic disease management and adverse outcomes. However, reports on HL in predialysis chronic kidney disease (CKD) patients are limited in Japan.

METHODS

From August 2019 to February 2020, the European Health Literacy Survey (Japanese version) and a patient background survey (highest level of education, income, social activities, and exercise habit) were conducted on adult predialysis CKD patients. We compared clinical parameters in two groups according to the average HL score of a healthy Japanese population. In addition, a median value of 42 items was used as a cutoff for extracting CKD patient background factors associated with HL since HLS-EU-Q47 included five items related to physical activity and exercise.

RESULTS

Valid responses were received from 200 patients. Median general HL index was 25.2 points. The high-HL group (≥ 25.3 points) showed a low proportion of male (56.7% vs. 70.9%, p = 0.038), high social activities (69.1% vs. 48.5%, p = 0.003), and high exercise habit (36.1% vs. 13.6%, p < 0.001). In the multivariate analysis, social activity [OR (95% CI); 2.12 (1.16-3.89), p = 0.015] and exercise habit [OR (95% CI); 2.39 (1.16-4.90), p = 0.018] were extracted as the only significant variable.

CONCLUSIONS

HL in Japanese predialysis CKD patients was associated with high social activity and exercise habit.

Eating Like a Rainbow: The Development of a Visual Aid for Nutritional Treatment of CKD Patients. A South African Project

Providing nutritional education for chronic kidney disease (CKD) patients in South Africa is complicated by several conditions: the population is composed of diverse ethnic groups, each with its own culture and food preferences; eleven languages are spoken and illiteracy is common in the lower socio-economic groups. Food preparation and storage are affected by the lack of electricity and refrigeration, and this contributes to a monotonous diet. In traditional African culture, two meals per day are often shared "from the pot", making portion control difficult. There is both under- and over-nutrition; late referral of CKD is common. Good quality protein intake is often insufficient and there are several misconceptions about protein sources. There is a low intake of vegetables and fruit, while daily sodium intake is high, averaging 10 g/day, mostly from discretionary sources. On this background, we would like to describe the development of a simplified, visual approach to the "renal diet", principally addressed to illiterate/non-English speaking CKD patients in Southern Africa, using illustrations to replace writing. This tool "Five steps to improve renal diet compliance", also called "Eating like a Rainbow", was developed to try to increase patients' understanding, and has so far only been informally validated by feedback from users. The interest of this study is based on underlining the feasibility of dietary education even in difficult populations, focusing attention on this fundamental issue of CKD care in particular in countries with limited access to chronic dialysis.

Functional health literacy and knowledge of renal patients on pre-dialytic treatment

OBJECTIVE:

to analyze the functional health literacy (FHL), i.e., understanding and knowledge about chronic renal disease of 60 patients in pre-dialytic treatment.

METHOD:

this is a cross-sectional study. FHL was measured by B-TOFHLA; and the knowledge, by questionnaire. Pearson correlation and Chi-square tests were carried out as well as linear regression models.

RESULTS:

all respondents presented inadequate FHL, and most showed insufficient knowledge about the disease and treatment. Low schooling was a predictive factor for worst FHL scores. Insufficient knowledge was related to age and compromised cognition.

CONCLUSION:

although association between predictive variables has not been found, limited capability to obtain and use health-related information and insufficient knowledge about their own condition and treatment can contribute to worse outcomes for CKD. Appropriate intervention strategies are necessary to deal with limited FHL and also greater knowledge and ability of professionals to deal with the matter.

Health literacy in kidney disease: Review of the literature and implications for clinical practice

Health literacy is the capacity of an individual to understand information related to a disease in order to make an informed decision. In patients with kidney diseases, studies have reported increasing impact of limited health literacy on health outcomes. Our paper discusses current literature on health literacy in kidney diseases.

Understanding the influence of educational attainment on kidney health and opportunities for improved care

Educational attainment is an important but often overlooked contributor to health outcomes in patients with kidney disease. Those with lower levels of education have an increased risk of ESRD, complications of peritoneal dialysis, worse transplant outcomes, and mortality. Mediators of these associations are poorly understood but involve a complex interplay between health knowledge, behaviors, and socioeconomic and psychosocial factors. Interventions targeting these aspects of care have the potential to reduce disparities related to educational attainment; however, few programs have been described that specifically address this issue. Future research efforts should not only systematically assess level of educational attainment but also report the differential impact of interventions across educational strata. In addition, routine measurement of health literacy may be useful to identify high-risk patients independent of years of schooling. A better understanding of the influence of educational attainment on kidney health provides an opportunity to improve the care and outcomes of vulnerable patients with kidney disease.

Patient engagement and patient-centred care in the management of advanced chronic kidney disease and chronic kidney failure

PURPOSE

The purpose of this article is to review the current status of patient-centred care (PCC) and patient engagement (PE) in the management of patients with advanced chronic kidney disease (CKD) and end-stage renal disease (ESRD), to identify some of the barriers that exist to the achievement of PCC and PE, and to describe how these barriers can be overcome.

SOURCES OF INFORMATION

The review is based on the professional experience of one of the authors (RB) as a Nephrologist and health care consultant, on the MBA thesis of one of the authors (SS) and on a review of pertinent internet-based information and published literature.

FINDINGS

Evidence exists that, currently, the care of patients with advanced CKD and ESRD is not fully patient-centred or fully supportive of PE. A number of barriers exist, including: conflict with other priorities; lack of training and fear of change; the unequal balance of power between patients and providers; physician culture and behaviour; the fee-for-service model of physician compensation; slow implementation of electronic health records; and, fear of accountability. These barriers can be overcome by committed leadership and the development of an information-based implementation plan. Established Renal Agencies in Canada appear interested in facilitating this work by collaborating in the development of a toolkit of recommended educational resources and preferred implementation practices for use by ESRD Programs.

LIMITATIONS

A limitation of this review is the absence of a substantial pre-existing literature on this topic.

IMPLICATIONS

Receiving care that is patient-centred and that promotes PE benefits patients with serious chronic diseases such as advanced CKD and ESRD. Considerable work is required by ESRD Programs to ensure that such care is provided. Canadian Renal Agencies can play an important role by ensuring that ESRD Programs have access to essential educational material and proven implementation approaches and that implementation successes are celebrated. In this area, enabling policies are required, as are clinical research studies focusing on the measurement of outcomes.
