Development and results of a kidney disease knowledge survey given to patients with CKD

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.

Use of a Supportive Kidney Care Video Decision Aid in Older Patients: A Randomized Controlled Trial

BACKGROUND

There are few studies of patient-facing decision aids that include supportive kidney care as an option. We tested the efficacy of a video decision aid on knowledge of supportive kidney care among older patients with advanced CKD.

METHODS

Participants (age ≥ 65 years with advanced CKD) were randomized to receive verbal or video education. Primary outcome was knowledge of supportive kidney care (score range 0-3). Secondary outcomes included preference for supportive kidney care, and satisfaction and acceptability of the video.

RESULTS

Among all participants (n = 100), knowledge of supportive kidney care increased significantly after receiving education (p < 0.01); however, there was no difference between study arms (p = 0.68). There was no difference in preference for supportive kidney care between study arms (p = 0.49). In adjusted analyses, total health literacy score (aOR 1.08 [95% CI: 1.003-1.165]) and nephrologists' answer of "No" to the Surprise Question (aOR 4.87 [95% CI: 1.22-19.43]) were associated with preference for supportive kidney care. Most felt comfortable watching the video (96%), felt the content was helpful (96%), and would recommend the video to others (96%).

CONCLUSIONS

Among older patients with advanced CKD, we did not detect a significant difference between an educational verbal script and a video decision aid in improving knowledge of supportive kidney care or preferences. However, patients who received video education reported high satisfaction and acceptability ratings. Future research will determine the effectiveness of a supportive kidney care video decision aid on real-world patient outcomes.

Validity, reliability, and application of the electronic version of a chronic kidney disease patient awareness questionnaire: a pilot study

OBJECTIVES

A questionnaire which provides desirable reliability and validity has been previously developed to assess the disease awareness of diagnosed chronic kidney disease (CKD) patients. However, conventional paper questionnaires often have disadvantages, including recall bias. To substantially improve this, we therefore aimed to explore the feasibility of developing a smartphone-based electronic version (e-version) based upon its original paper version and subsequently tested its validity, reliability, and applicability.

METHODS

A pilot study was conducted at Guangdong Provincial Hospital of Chinese Medicine in Guangzhou, China, during August 2019. The e-version had identical content to the paper version and was adapted in terms of layout and assisted functions via the Wechat-incorporated Wen-Juan-Xing platform. Eligible patients with diagnosed CKD were invited to participate and were assigned the e-version. Randomly selected respondents received a test-retest of the same e-version 2 weeks after their first completion. In some instances, psychometric properties, including validity and reliability of the e-version, were examined. In others, its clinical application was also tested, which included comparisons among the clinical profiles of patients who had/had not responded to the questionnaire as well as patients with above or below average questionnaire scores.

RESULTS

Of the 225 patients screened, 217 were enrolled to participate, with a response rate of 52.5%. Desirable reliability (Cronbachα = 0.962, ICC for total scores = 0.948), while good convergent validity (Cronbachα = 0.962) and low discriminant validity (one extracted component), of the e-version were detected. Performing inter-group comparisons highlighted statistical differences in terms of higher education level (z = -2.436, P = 0.015) and earlier CKD stages (z = -1.978, P = 0.048), with these patients often preferring to respond. No significant differences were detected in the clinical profiles between respondents who obtained an above or below average questionnaire score.

CONCLUSION

The e-version is reliable but was not shown to be a valid approach. Audiences with higher education levels and less advanced disease condition may prefer to respond to the e-version. Adaptation of this e-questionnaire, from its original paper version, may not be a direct transition and meticulous modifications may be required during the transition process.

Validation of the Australian version of the Chronic Kidney Disease Self-Management instrument

AIM

The aim of this study is to evaluate the validity and reliability of the modified Chronic Kidney Disease Self-Management instrument in an English-speaking population.

BACKGROUND

There is growing evidence that self-management behaviours can improve outcomes for people with chronic kidney disease. However, there are few suitable instruments available.

DESIGN

The study was cross sectional, with a test-retest protocol.

METHOD

Adults with chronic kidney disease attending a primary health care between June and December 2015 completed the Chronic Kidney Disease Self-Management instrument. Construct validity was determined using exploratory factor analysis, internal consistency and test-retest reliability using Cronbach's α and intraclass correlation. For convergent validity, the relationships between knowledge, self-efficacy and self-management were investigated.

RESULTS

The Australian version of the Chronic Kidney Disease Self-Management instrument has 17 items grouped into four factors: self-integration, seeking social support, adherence to lifestyle modification and problem solving. The instrument demonstrated good reliability. Self-efficacy was positively correlated with self-management scores, although there was no correlation between chronic kidney disease knowledge and self-management.

CONCLUSIONS

The Australian version of the Chronic Kidney Disease Self-Management instrument was found to be a valid and reliable patient-reported outcome measure. It can be used in clinical practice to support self-management, as well as future research.

Measuring Patient Activation as Part of Kidney Disease Policy: Are We There Yet?

Optimal care occurs when patients possess the skills, knowledge, and confidence needed to effectively manage their health. Promoting such patient activation in kidney disease care is increasingly being prioritized, and patient activation has recently emerged as central to kidney disease legislative policy in the United States. Two options of the Centers for Medicare and Medicaid Services Kidney Care Choices model-the Kidney Care First option and the Comprehensive Kidney Care Contracting option-now include patient activation as a quality metric; both models specifically name the patient activation measure (PAM) as the patient-reported outcome to use when assessing activation in kidney disease. Because nephrology practices participating in these models will receive capitated payments according to changes in patients' PAM scores, it is time to more critically evaluate this measure as it applies to patients with kidney disease. In this review, we raise important issues related to the PAM's applicability to kidney health, review and summarize existing literature that applies this measure to patients with kidney disease, and outline key elements to consider when implementing the PAM into practice and policy. Our aim is to spur further dialogue regarding how to assess and address patient activation in kidney disease to facilitate best practices for supporting patients in the successful management of their kidney health.

Ethnic influence on nonalcoholic fatty liver disease prevalence and lack of disease awareness in the United States, 2011-2016

BACKGROUND

Nonalcoholic fatty liver disease (NAFLD) is a rising global disease associated with clinical and economic burdens.

OBJECTIVES

We aimed to quantify NAFLD prevalence and awareness to provide stakeholders necessary information to combat NAFLD burden.

METHODS

This study utilizes data from the National Health and Nutrition Examination Survey 2011-2016 and included 4538 adult participants who did not have heavy drinking or viral hepatitis history. The US fatty liver index defined NAFLD and NAFLD fibrosis score defined fibrosis. NAFLD awareness was captured by questionnaire.

RESULTS

Amongst the study population of 4538 persons, NAFLD prevalence was 32.5%, lowest in non-Hispanic Blacks (18.0%) and Asians (18.1%), highest amongst Mexican Americans (48.4%). Within the NAFLD group, advanced fibrosis was highest in non-Hispanic Blacks (28.5%) and lowest amongst non-Hispanic Asians (2.7%). Of the 1473 (97.5%) NAFLD participants who answered NAFLD awareness question, 90% visited a healthcare centre at least once in the past year, but only 5.1% were aware of having NAFLD. On weighted population estimates, 77.33 million persons had NAFLD, 17.63 million had advanced fibrosis, and 73.39 million NAFLD participants were not aware of having NAFLD.

CONCLUSIONS

Of 77.33 million people in the United States have NAFLD with 17.63 million having advanced fibrosis, with lowest prevalence in non-Hispanic Asians and highest in Mexican Americans. A conundrum exists amongst non-Hispanic Blacks who have low NAFLD prevalence but highest prevalence of advanced fibrosis. Awareness of NAFLD was low across all ethnicities. Effort is needed to improve disease awareness whilst addressing NAFLD clinical burden across ethnicities.

Health literacy, nutrition knowledge, and health care transition readiness in youth with chronic kidney disease or hypertension: A cross-sectional study

This study evaluates the associations of nutrition knowledge and health literacy with health care transition (HCT) readiness and self-management in adolescents and young adults (AYAs) with chronic kidney disease (CKD) or hypertension. Chronically ill AYAs with poor HCT or self-management skills are less likely to achieve favorable health outcomes as they enter adulthood. Health literacy and nutrition knowledge, which are identified as important contributors to health outcomes, may suggest important points of interventions to improve self-management skills. For the study, we enrolled 59 consecutive patients ages 12-29, with a diagnosis of CKD or hypertension at pediatric- and adult-focused clinics in the United States. Participants completed measures of nutrition knowledge, health literacy, and the Self-management and Transition to Adulthood with R_x = treatment (STAR_x) questionnaire. Correlation tests and multivariate regressions were employed for data analysis. The findings show that health literacy was positively associated with self-management skills (p = .050), communication with providers (p = .002) and overall HCT (p = .001) after adjusting for key variables. Disease-specific nutrition knowledge positively predicted communication with providers (p = .002) and overall HCT (p < .001) after adjusting for key variables. Therefore, health literacy and nutrition knowledge predicted self-management and transition readiness. Testing for these skills should be considered in clinics and HCT preparation for AYAs with chronic conditions.

A Virtual Multidisciplinary Care Program for Management of Advanced Chronic Kidney Disease: Matched Cohort Study

Background

It is not well established whether a virtual multidisciplinary care program for persons with advanced chronic kidney disease (CKD) can improve their knowledge about their disease, increase their interest in home dialysis therapies, and result in more planned outpatient (versus inpatient) dialysis starts.

Objective

We aimed to evaluate the feasibility and preliminary associations of program participation with disease knowledge, home dialysis modality preference, and outpatient dialysis initiation among persons with advanced CKD in a community-based nephrology practice.

Methods

In a matched prospective cohort, we enrolled adults aged 18 to 85 years with at least two estimated glomerular filtration rates (eGFRs) of less than 30 mL/min/1.73 m2 into the Cricket Health program and compared them with controls receiving care at the same clinic, matched on age, gender, eGFR, and presence of heart failure and diabetes. The intervention included online education materials, a virtual multidisciplinary team (nurse, pharmacist, social worker, dietician), and patient mentors. Prespecified follow-up time was nine months with extended follow-up to allow adequate time to determine the dialysis start setting. CKD knowledge and dialysis modality choice were evaluated in a pre-post survey among intervention participants.

Results

Thirty-seven participants were matched to 61 controls by age (mean 67.2, SD 10.4 versus mean 68.8, SD 9.5), prevalence of diabetes (54%, 20/37 versus 57%, 35/61), congestive heart failure (22%, 8/37 versus 25%, 15/61), and baseline eGFR (mean 19, SD 6 versus mean 21, SD 5 mL/min/1.73 m2), respectively. At nine-month follow-up, five patients in each group started dialysis (P=.62). Among program participants, 80% (4/5) started dialysis as an outpatient compared with 20% (1/5) of controls (OR 6.28, 95% CI 0.69-57.22). In extended follow-up (median 15.7, range 11.7 to 18.1 months), 19 of 98 patients started dialysis; 80% (8/10) of the intervention group patients started dialysis in the outpatient setting versus 22% (2/9) of control patients (hazard ratio 6.89, 95% CI 1.46-32.66). Compared to before participation, patients who completed the program had higher disease knowledge levels (mean 52%, SD 29% versus mean 94%, SD 14% of questions correct on knowledge-based survey, P<.001) and were more likely to choose a home modality as their first dialysis choice (36%, 7/22 versus 68%, 15/22, P=.047) after program completion.

Conclusions

The Cricket Health program can improve patient knowledge about CKD and increase interest in home dialysis modalities, and may increase the proportion of dialysis starts in the outpatient setting.

Perceived and Objective Kidney Disease Knowledge in Patients With Advanced CKD Followed in a Multidisciplinary CKD Clinic

Background:

One of the key components of multidisciplinary CKD clinics is education; however, kidney disease knowledge among patients followed in these clinics is not routinely measured.

Objective:

The aim of this study was to determine objective and perceived kidney disease knowledge and patient characteristics associated with knowledge among patients followed in a multi-care kidney clinic.

Design:

This is a cross-sectional survey study.

Setting:

This study was conducted in a multi-care kidney clinic in Ontario, Canada.

Patients:

Patients who did not speak English, who were unable to read due to significant vision impairment, or who had a known history of dementia or significant cognitive impairment were excluded.

Measurements:

Perceived kidney disease knowledge was evaluated using a previously validated 9-item survey (PiKS). Each question on the perceived knowledge survey had 4 possible responses, ranging from “I don’t know anything” (1) to “I know a lot” (4). Objective kidney disease knowledge was evaluated using a previously validated survey (KiKS).

Methods:

The association between patient characteristics and perceived and objective kidney disease knowledge was determined using linear regression.

Results:

A total of 125 patients were included, 57% were male, the mean (SD) age and eGFR were 66 (13) years and 16 (5.9) mL/min/1.73 m², respectively. The median (IQR) objective and perceived knowledge survey scores were 19 out of 27 (16, 21) and 2.9 out of 4 (2.4, 3.2), respectively. Only 25% of patients answered correctly that CKD can be associated with no symptoms, and 64% of patients identified correctly that the kidneys make urine. More than 60% of patients perceived themselves to know nothing or only a little about medications that help or hurt the kidney. Older age was independently associated with lower perceived and objective knowledge, but sex, income, and educational attainment were not.

Limitations:

This is a single-center study. Cognitive impairment was based on the treating team’s informal assessment or prior documentation in the chart; formal cognitive testing was not performed as part of this study.

Conclusions:

Despite resource-intensive care, CKD knowledge of patients followed in a multidisciplinary clinic was found to be modest. Whether enhanced educational strategies can improve knowledge and whether increasing knowledge improves patient outcomes warrants further study.

Knowledge About Immunosuppressant Medication and Its Correlates in a German Kidney Transplant Population - Results of a KTx360° Substudy

PURPOSE

After organ transplantation, adherence to immunosuppressive medication (ISM) is crucial to prevent organ rejection. To enable adherence, patients need to be well informed about the different aspects associated with their ISM. However, literature suggests that knowledge regarding ISM is often inadequate.

PATIENTS AND METHODS

In a cross-sectional study, 702 patients after kidney transplantation participating in a structured multimodal follow-up program (KTx360°) were evaluated. We utilized a self-developed questionnaire which has been successfully used before to measure patients' knowledge about the ISM. Above that we aimed to evaluate potential associations between sociodemographic, medical, donation-specific, and psychosocial variables including adherence, levels of depression and anxiety, perceived social support, and cognitive functioning with the knowledge level.

RESULTS

The mean age of the patients was 52.4 years, 58.1% were men, and 66.6% were living in a partnership. The mean time since transplantation was 65.1 months. On average, patients answered 70.9% of the questions correctly. The percentage of correct answers per question differed considerably (54%-92%). In univariate analyses, knowledge levels were positively associated with female gender, current partnership, German as first language and better cognitive functioning. However, the effect sizes were small.

CONCLUSION

Taking into account that the patients after KTx can be expected to answer all questions correctly as they aim at basic knowledge, an average result of 70.9% corresponds to a moderate knowledge level. Consequently, the current educational approaches do not seem to be sufficient to inform all patients adequately. Further research is necessary on how to improve health knowledge in the long term.

The Relationship of Disease-Specific Knowledge and Health Literacy With the Uptake of Self-Care Behaviors in CKD

INTRODUCTION

Individuals with chronic kidney disease (CKD) generally have poor participation in self-care. We hypothesized that greater kidney disease knowledge and health literacy would associate with better self-care.

METHODS

We enrolled 401 participants with non-dialysis-dependent CKD from one academic center in this cross-sectional study. Validated surveys were used to assess health literacy level (inadequate vs. adequate; Rapid Estimate of Adult Literacy in Medicine), perceived kidney disease knowledge (Perceived Kidney Disease Knowledge Survey [PiKS]), objective kidney disease knowledge (Kidney Disease Knowledge Survey [KiKS]), and a CKD self-care measure was constructed as the sum of self-reported self-care behaviors using the adapted Summary of Diabetes Self-Care Activities Assessment. The association between health literacy level, PiKS scores, KiKS scores, and the CKD self-care measure was assessed with multivariable adjusted linear regression models.

RESULTS

Participants had a mean age of 57 years and 17.7% had inadequate health literacy. PiKS scores were positively associated with the CKD self-care measure (β = 1.05, 95% confidence interval [CI] 0.50-1.63), and a positive trend was observed for KiKS scores and the CKD self-care measure (β = 0.30, 95% CI: -0.12 to 0.72). Health literacy was not associated with CKD self-care measure.

CONCLUSION

Objective kidney disease knowledge is likely necessary, but not sufficient for self-care and may depend on the level of health literacy. Perceived kidney knowledge may offer a novel target to assess patients at risk for poor self-care, and be used in targeted educational interventions.

Awareness and Discussions About Chronic Kidney Disease Among African-Americans with Chronic Kidney Disease and Hypertension: a Mixed Methods Study

BACKGROUND

Routine primary care visits provide an educational opportunity for African-Americans with chronic kidney disease (CKD) and CKD risk factors such as hypertension. The nature of patient-physician discussions about CKD and their impact on CKD awareness in this population have not been well explored.

OBJECTIVE

To characterize patient CKD awareness and discussions about CKD between patients and primary care physicians (PCPs).

DESIGN

Mixed methods study.

PATIENTS

African-American patients with uncontrolled hypertension (≥ 140/90 mmHg) and CKD (albuminuria or eGFR < 60 ml/min/1.73 m2) recruited from an urban primary care clinic.

MAIN MEASURES

We assessed patient CKD awareness with questionnaires and audio-recorded patients-PCP discussions during a routine visit. We characterized discussions and used multivariate regression analysis to identify independent patient and visit predictors of CKD awareness or CKD discussions.

RESULTS

Among 48 African-American patients with uncontrolled hypertension and CKD, 29% were aware of their CKD. After adjustment, CKD awareness was associated with moderate-severe CKD (stages 3-4) (vs. mild CKD [stages 1-2]) (prevalence ratio [PR] 2.82; 95% CI 1.18-6.78) and inversely associated with diabetes (vs. without diabetes) (PR 0.28; 95% CI 0.10-0.75). CKD discussions occurred in 30 (63%) visits; most focused on laboratory assessment (n = 23, 77%) or risk factor management to delay CKD progression (n = 19, 63%). CKD discussions were associated with moderate-severe CKD (vs. mild CKD) (PR 1.57; 95% CI 1.04-2.36) and diabetes (vs. without diabetes) (PR 1.42; 95% CI 1.09-1.85), and inversely associated with uncontrolled hypertension (vs. controlled) (PR 0.58; 95% CI 0.92-0.89). In subgroup analysis, follow-up CKD awareness did not change by presence or absence of CKD discussion (10.5% vs. 7.7%, p = 0.8).

CONCLUSIONS

In patients at risk of CKD progression, few were aware of CKD, and CKD discussions were not associated with CKD awareness. More resources may be needed to enhance the clarity of clinical messages regarding CKD and its significance for patients' health.

Patient-Related Barriers to Timely Dialysis Access Preparation: A Qualitative Study of the Perspectives of Patients, Family Members, and Health Care Providers

Rational & Objective

A key aspect of smooth transition to dialysis is the timely creation of a permanent access. Despite early referral to kidney care, initiation onto dialysis is still suboptimal for many patients, which has clinical and cost implications. This study aimed to explore perspectives of various stakeholders on barriers to timely access creation.

Study Design

Qualitative study.

Setting & Participants

Semi-structured interviews with 96 participants (response rate, 67%), including patients with stage 4 chronic kidney disease (n = 30), new hemodialysis patients with (n = 18) and without (n = 20) permanent access (arteriovenous fistula), family members (n = 19), and kidney health care providers (n = 9).

Analytical Approach

Thematic analysis.

Results

Patients reported differential levels of behavioral activation toward access creation: avoidance/denial, wait and see, or active intention. 6 core themes were identified: (1) lack of symptoms, (2) dialysis fears and practical concerns (exaggerated fear, pain, cost, lifestyle disruptions, work-related concerns, burdening their families), (3) evaluating value against costs/risks of access creation (benefits, threat of operation, viability, prompt for early initiation), (4) preference for alternatives, (5) social influences (hearsay, family involvement, experiences of others), and (6) health care provider interactions (mistrust, interpersonal tension, lack of clarity in information). Themes were common to all groups, whereas nuanced perspectives of family members and health care providers were noted in some subthemes.

Limitations

Response bias.

Conclusions

Individual, interpersonal, and psychosocial factors compromise dialysis preparation and contribute to suboptimal dialysis initiation. Our findings support the need for interventions to improve patient and family engagement and address emotional concerns and misperceptions about preparing for dialysis.

The role of patient portals in enhancing self-care in patients with renal conditions

Web-based portals enable patients to access their electronic health records, including test results and clinical documents, from anywhere with Internet access. Some portals also serve as a means of two-way communication between patients and healthcare professionals and provide a platform for the recording of patient-entered data such as home blood pressure readings. Such systems are designed to encourage patient participation in the management of their condition, and ultimately to increase patient empowerment and self-management, which are associated with improved clinical outcomes. As an example of portal use in patients with renal conditions, we discuss the PatientView portal, which is offered free of cost to patients under the care of renal physicians in the UK. We present an account of its various features and briefly describe the user experience. Previous studies examining the impact of this portal on patient care have been very positive; it appears to be popular among users and overall levels of satisfaction with the service are high. As the use of patient portals increases, we discuss barriers to the more widespread use of portals. We offer suggestions on how the care of patients with renal conditions can be enhanced in the future by further developing the existing features, learning from experiences of other patient portals and providing better integration of portal use into the current model of care.

Health literacy and patient outcomes in chronic kidney disease: a systematic review

Background

Limited health literacy affects 25% of people with chronic kidney disease (CKD), and may reduce self-management skills resulting in poorer clinical outcomes. By disproportionately affecting people with low socio-economic status and non-white ethnicity, limited health literacy may promote health inequity.

Methods

We performed a systematic review of quantitative studies of health literacy and clinical outcomes among adults with CKD.

Results

A total of 29 studies (13 articles; 16 conference abstracts) were included. One included non-USA patients. Of the 29 studies, 5 were cohort studies and 24 were cross-sectional. In all, 18 300 patients were studied: 4367 non-dialysis CKD; 13 202 dialysis; 390 transplant; 341 unspecified. Median study size was 127 [interquartile range (IQR) 92-238)], but 480 (IQR 260-2392) for cohort studies. Median proportion of non-white participants was 48% (IQR 17-70%). Six health literacy measures were used. Outcomes included patient attributes, care processes, clinical/laboratory parameters and 'hard' clinical outcomes. Limited health literacy was significantly, independently associated with hospitalizations, emergency department use, missed dialysis sessions, cardiovascular events and mortality (in cohort studies). Study quality was high (1 study), moderate (3 studies) and poor (25 studies), limited by sampling methods, variable adjustment for confounders and reduced methodological detail given in conference abstracts.

Conclusions

There is limited robust evidence of the causal effects of health literacy on patient outcomes in CKD. Available evidence suggests associations with adverse clinical events, increased healthcare use and mortality. Prospective studies are required to determine the causal effects of health literacy on outcomes in CKD patients, and examine the relationships between socio-economic status, comorbidity, health literacy and CKD outcomes. Intervention development and evaluation will determine whether health literacy is a modifiable determinant of poor outcomes in CKD.

Novel educational and goal-setting tool to improve knowledge of chronic kidney disease among liver transplant recipients: A pilot study

Introduction

Liver transplant (LT) recipients have limited understanding of post-transplant chronic kidney disease (CKD) despite an excellent pre-existing framework of transplant care. This pilot study examined the efficacy and feasibility of a tailored educational and goal-setting tool in improving CKD knowledge among LT recipients with early-stage CKD.

Methods

In this prospective cohort study, we administered the CKD educational and goal-setting tool to 81 LT recipients between 7/1/2016 and 12/31/2017. We excluded patients with simultaneous liver-kidney transplantation, eGFR<30 ml/min, non-English speaking, on hemodialysis or listed for kidney transplantation. The pre- and post-education knowledge scores were compared using a paired t-test. Linear regression was used to assess the independent predictors of change in knowledge score.

Results

Mean age was 56.3 years, 69.1% were males, 85.2% were Caucasians and mean eGFR was 61.2 ± 20.0 ml/min. The CKD educational and goal-setting tool improved the CKD knowledge scores among LT recipients (pre: 71.8 ± 16.6%, post: 83.3 ± 10.4%; p<0.001). In an adjusted model (r² = 0.75), those with lower pre-education knowledge scores had the most improvement in their post-education knowledge scores (β = -83.2; p<0.001). Two-thirds stated their most important self-management goal and reported motivation to follow this goal. Time spent for the CKD education was approximately 15 minutes.

Conclusions

A simple LT-specific patient educational and goal-setting tool effectively improved CKD knowledge. Implementation of this tailored intervention will improve CKD awareness and may promote goal-setting in the target population.

Integrating Risk-Based Care for Patients With Chronic Kidney Disease in the Community: Study Protocol for a Cluster Randomized Trial

Background:

A risk-based model of care for managing patients with chronic kidney disease (CKD) using the Kidney Failure Risk Equation (KFRE) has been successfully integrated into nephrology care pathways in several jurisdictions. However, as most patients with CKD can be managed in primary care, the next pertinent steps would be to integrate the KFRE into primary care pathways.

Objective:

Using a risk-based approach for guiding CKD care in the primary care setting, the objective of the study is to develop, implement, and evaluate tools that can be used by patients and providers.

Design:

This study is a multicenter cluster randomized control trial.

Setting:

Thirty-two primary care clinics belonging to the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) across Manitoba and Alberta.

Patients:

All patients at least 18 years old or older with CKD categories G3-G5 attending the participating clinics; we estimate each clinic will have an average of 185 patients with CKD.

Methods:

Thirty-two primary care clinics will be randomized to receive either an active knowledge translation intervention or no intervention. The intervention involves the addition of the KFRE and decision aids to clinics’ Data Presentation Tool (DPT), as well as patient-facing visual aids, a medical detailing visit, and sentinel feedback reports. Control clinics will only be exposed to current guidelines for CKD management, without active dissemination.

Measurements:

Data from the CPCSSN repository will be used to assess whether a risk-based care approach affected management of CKD. Primary outcomes are as follows: the proportion of patients with measured urine albumin-to-creatinine ratio, and the proportion of patients being appropriately treated with angiotensin-converting enzyme inhibitor or angiotensin receptor blockers. Secondary outcomes are as follows: the optimal management of diabetes (hemoglobin A1C <8.5%, and the use of sodium-glucose cotransporter-2 inhibitors in CKD G3 patients), hypertension (office blood pressure <130/80 for patients with diabetes, 140/90 for those without), and cardiovascular risk (statin prescription); prescriptions of nonsteroidal anti-inflammatory drugs; and decline in estimated glomerular filtration rate (eGFR). In addition, in a substudy, we will measure CKD-specific health literacy and trust in physician care via surveys administered in the clinic post-visit. At the provider level, we will measure satisfaction with the risk prediction tools. Lastly, at the health system level, outcomes include cost of CKD care, and appropriate referrals for patients at high risk of kidney failure based on provincial guidelines. Primary and secondary outcomes will be measured at the patient level and enumerated at the clinic level 1 year after the intervention implementation, except for decline in eGFR, which will be measured 2 years postintervention.

Limitations:

Limitations include scalability of the proposal in other health care systems.

Conclusions:

If successful, this intervention has the potential to improve the management of patients with CKD within Canadian primary care settings, leading to health and economic benefits, and influencing practice guidelines.

Health Literacy Mediates Racial Disparities in Cardiopulmonary Resuscitation Knowledge among Chronic Kidney Disease Patients

Black patients with chronic kidney disease (CKD) receive more cardiopulmonary resuscitation (CPR) than other racial groups, and knowledge of CPR influences preferences for care. As limited health literacy disproportionately affects Blacks and contributes to disparities in end-of-life (EOL) care, we investigated whether health literacy mediates racial disparities in CPR knowledge. Black and White adult patients with advanced CKD completed CPR knowledge surveys. Health literacy was assessed using the Rapid Estimate of Adult Literacy in Medicine. Among 149 patients, Black patients were more likely to have limited health literacy and lower mean CPR knowledge scores than White patients. In adjusted analyses, health literacy mediated racial differences in CPR knowledge. Knowledge of CPR is lower among Black compared with White CKD patients and health literacy is a mediator of this difference. Future CPR educational interventions should target health literacy barriers to improve informed decision-making and decrease racial disparities at the end of life.

Kidney Disease Awareness and Knowledge among Survivors ofAcute Kidney Injury

BACKGROUND

Acute kidney injury (AKI) survivors are at risk for chronic kidney disease, recurrent AKI, and cardiovascular disease. The transition from hospital to ambulatory care is an opportunity to reduce these sequelae by launching self-care plans through effective patient education. How well AKI survivors are informationally prepared to apply kidney-specific self-care is unknown. The purpose of this study was to identify awareness and disease-specific knowledge among AKI survivors.

METHODS

We performed a cross-sectional survey of AKI-related awareness and knowledge in 137 patients with Kidney Disease Improving Global Outcomes Stage II or III AKI near the time of hospital discharge. Patients were asked (1) "Did you experience AKI while in the hospital?" and (2) "Do you have a problem with your kidney health?" Objective knowledge of AKI was evaluated with a 15-item adapted version of the validated Kidney Knowledge Survey that included topics such as common causes, risk factors, and how AKI is diagnosed.

RESULTS

Median age was 54 (interquartile range 43-63) and 81% were white. Eighty percent of patients were unaware that they had experienced AKI and 53% were both unaware they had experienced AKI or had a "problem with their kidneys." Multivariable logistic regression identified being male and lack of nephrology consult as predictors of unawareness with ORs of 3.92 (95% CI 1.48-10.33) and 5.10 (95% CI 1.98-13.13), respectively. Less than 50% recognized nonsteroidal anti-inflammatory drugs, contrast, or phosphate-based cathartics as risk factors for AKI. Two-thirds of patients did not agree that they knew a lot about AKI and more than 80% desired more information.

CONCLUSIONS

Most patients with moderate to severe AKI are unaware of their condition, lack understanding of risk factors for recurrent AKI, and desire more information. Patient-centered communication to optimize awareness, understanding, and care will require coordinated educational strategies throughout the continuum of AKI care.

Patient-selected media and knowledge of risk to kidneys of nonsteroidal anti-inflammatory drugs

OBJECTIVES

Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause community-acquired acute kidney injury, especially in high-risk populations. Both the U.S. Food and Drug Administration (FDA) medication guide and over-the-counter labeling vaguely describe kidney risks of NSAIDs and do not provide information for patients to evaluate their risk for kidney problems. The purpose of this study was to use a mobile application to evaluate the impact of patient choice of media delivering NSAID avoidance education on patient knowledge about kidney risks associated with NSAIDs.

DESIGN

Prospective cohort study. The mobile application was used to deliver either a redesigned FDA medication guide or a video focused on NSAID risks (selected by the patient), followed by patient knowledge questions (PKQs) and a kidney risk assessment.

SETTING AND PARTICIPANTS

One hundred fifty adult primary care patients in southeast Michigan.

MAIN OUTCOME MEASURES

The primary outcome was the score on 5 NSAID PKQs between the media selected. Secondary outcomes included characterization of media choice among different demographic and NSAID kidney risk groups. The relationship between kidney risk assessment and self-reported NSAID avoidance behavior also was evaluated.

RESULTS

The majority of participants (72.7%) chose to review print material. Those that chose print had significantly higher PKQ scores (5 total points) compared with participants who selected the video: mean scores 4.2 ± 0.9 with print and 3.8 ± 1.0 with video (P = 0.034). Older patients (>65 years) had significantly lower PKQ scores compared with other age groups. Forty-four percent of individuals (n = 66) reported current NSAID use, and 65% stated that they would avoid NSAIDs after the selected education material.

CONCLUSION

Scores for questions related to NSAID kidney risk knowledge were higher among participants who chose print compared with video education material. Education regarding NSAID kidney risks encouraged patients to limit their use. Targeted education may be beneficial in high-risk (e.g., older) patients and should be further studied.

Effectiveness of self-management programme in people with chronic kidney disease: A pragmatic randomized controlled trial

AIMS

To examine the effectiveness of a self-management intervention compared with usual care in adults with chronic kidney disease (CKD) on self-management, knowledge, self-efficacy, health-related quality of life, and blood pressure.

DESIGN

A parallel group randomized controlled trial.

METHODS

Patients aged ≥ 18 years with CKD stages 3-5 were recruited between November 2015 and June 2016. Participants were randomly allocated into either the intervention (N = 68) or control group (N = 67). The control group received usual care, while the intervention group received usual care plus a self-management programme from a nurse. The intervention was guided by social cognitive theory (SCT) and included a face-to-face educational session followed by telephone support. Both groups were followed for 16 weeks.

RESULTS

There were no significant differences in self-management, knowledge, self-efficacy, health-related quality of life, and blood pressure between the two groups at baseline. At week 16, compared with the control group, large effect sizes for improved self-management, knowledge, and self-efficacy were detected. For health-related quality of life, the physical and mental health components significantly improved. However, no significant differences in either systolic or diastolic blood pressures were found.

CONCLUSION

In earlier stages of CKD, a simple self-management education benefits patients.

IMPACT

Effective self-management in the earlier stages of CKD contributes to slowing its progression, improving health outcomes and lowering the burden on healthcare systems. This study demonstrated that SCT increases CKD self-management by strengthening knowledge and self-efficacy. Nurses can give this education.

Patients,' Nephrologists,' and Predicted Estimations of ESKD Risk Compared with 2-Year Incidence of ESKD

BACKGROUND AND OBJECTIVES

The rate of progression to ESKD is variable, and prognostic information helps patients and physicians plan for future ESKD. We assessed the estimations of ESKD risk of patients with CKD and physicians and compared them with risk calculators and outcomes at 2 years.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

This prospective observational study assessed 257 adult patients with CKD stages 3-5 and their nephrologists at University of California, San Diego and Veterans Affairs San Diego CKD clinics. Patients' and nephrologists' estimations of 2-year ESKD risk were evaluated, and objective estimation of 2-year risk was determined using kidney failure risk equations; actual incidence rates of ESKD and death were ascertained by chart review. Participants' baseline characteristics were compared across kidney failure risk equation risk levels and according to whether patients' estimations were more optimistic or pessimistic than physicians' estimations. We examined correlations between estimations and compared estimations with outcomes using c statistics and calibration plots.

RESULTS

Average age was 65 (±13) years old, and eGFR was 34 (±13) ml/min per 1.73 m2. Overall, 13% reached ESKD, and 9% died. About one quarter of patients gave estimates that were >20% more optimistic than physicians, and more than one in ten gave estimates that were >20% more pessimistic. Physicians' and kidney failure risk equation estimations had the strongest correlation (r=0.72; P<0.001) compared with 0.50 (P<0.001) between physicians and patients and 0.47 (P<0.001) between patients and kidney failure risk equation. Although all three estimations provided reasonable risk rankings (c statistics >0.8), physicians and patients overestimated risk compared with actual outcomes; no patient whose physician estimated a risk of ESKD <15% reached ESKD at 2 years. The kidney failure risk equation was best calibrated to actual ESKD risk.

CONCLUSIONS

Compared with actual ESKD incidence, the kidney failure risk equation outperformed patients' and physicians' estimations of ESKD incidence. Patients and physicians overestimated risk compared with the kidney failure risk equation.

A Digital Modality Decision Program for Patients With Advanced Chronic Kidney Disease

BACKGROUND

Patient education regarding end-stage renal disease (ESRD) has the potential to reduce adverse outcomes and increase the use of in-home renal replacement therapies.

OBJECTIVE

This study aimed to investigate whether an online, easily scalable education program can improve patient knowledge and facilitate decision making regarding renal replacement therapy options.

METHODS

We developed a 4-week online, digital educational program that included written information, short videos, and social networking features. Topics included kidney transplant, conservative management, peritoneal dialysis, in-home hemodialysis, and in-center hemodialysis. We recruited patients with advanced chronic kidney disease (stage IV and V) to enroll in the online program, and we evaluated the feasibility and potential impact of the digital program by conducting pre- and postintervention surveys in areas of knowledge, self-efficacy, and choice of ESRD care.

RESULTS

Of the 98 individuals found to be eligible for the study, 28 enrolled and signed the consent form and 25 completed the study. The average age of participants was 65 (SD 15) years, and the average estimated glomerular filtration rate was 21 (SD 6) ml/min/1.73 m². Before the intervention, 32% of patients (8/25) were unable to make an ESRD treatment choice; after the intervention, all 25 participants made a choice. The proportion of persons who selected kidney transplant as the first choice increased from 48% (12/25) at intake to 84% (21/25) after program completion (P=.01). Among modality options, peritoneal dialysis increased as the first choice for 4/25 (16%) patients at intake to 13/25 (52%) after program completion (P=.004). We also observed significant increases in knowledge score (from 65 [SD 56] to 83 [SD 14]; P<.001) and self-efficacy score (from 3.7 [SD 0.7] to 4.3 [SD 0.5]; P<.001).

CONCLUSIONS

Implementation of a digital ESRD education program is feasible and may facilitate patients' decisions about renal replacement therapies. Larger studies are necessary to understand whether the program affects clinical outcomes.

The Effects of Group Discussion Based Education on the Promotion of Self-Management Behaviors in Hemodialysis Patients

Introduction: Improving self-management of the patients undergoing hemodialysis is an effective way to reduce complications and to improve the quality of life of them. The current study aims to assess the effects of group discussion on the promotion of self-management behaviors in hemodialysis patients.

Methods: In this quasi -experimental clinical trial study (with experimental and control groups) 60 patients were arranged in two experimental and control groups through using convenience sampling with random allocation. Self-management interventions were conducted on the experimental group during 3 to 4 sessions of group discussion. The control group received routine interventions. The data were collected through Li and colleagues' self-management standard questionnaire before and 3 months after the intervention. The data were analyzed via SPSS software version 13 and chi-square, t-test, Mann-Whitney, and Wilcoxon test.

Results: The results showed that the mean scores of four dimension of self-management including participation with the medical team, problem solving, self-care and emotional management after the implementation of group were significantly different between the experimental and control groups.

Conclusion: Based on the findings, group discussion was an effective educational method to promote self-management of chronic hemodialysis patients. Therefore, holding group discussion to reinforce the self- management behaviors in patients undergoing hemodialysis is recommended.

Meeting patients where they are: improving outcomes in early chronic kidney disease with tailored self-management support (the CKD-SMS study)

BACKGROUND

To achieve optimal health outcomes, people with chronic kidney disease must make changes in their everyday lives to self-manage their condition. This can be challenging, and there is a need for self-management support interventions which assist people to become successful self-managers. While interventions have been developed, the literature in this area is sparse and limited by lack of both individualisation and sound theoretical basis. The aim of this study was to implement and evaluate the Chronic Kidney Disease-Self-Management Support intervention: a theory-based, person-centred self-management intervention for people with chronic kidney disease stages 1-4.

METHODS

A single-sample, pre-post study of an individualised, 12-week intervention based upon principles of social-cognitive theory and person-centred care was conducted with patients attending outpatient renal clinics in Queensland, Australia (N = 66). Data were collected at T0 (pre-intervention) and T1 (post-intervention). Primary outcomes were self-efficacy and self-management behaviour.

RESULTS

There were significant, small-to-medium improvements in primary outcomes (self-efficacy: mean difference + 0.8, 95% CI 0.3-1.2, d = 0.4; self-management behaviour: mean difference + 6.2, 95% CI 4.5-7.9, d = 0.8). There were further significant improvements in secondary outcomes (blood pressure, disease-specific knowledge, physical activity, fruit and vegetable consumption, alcohol consumption, health-related quality of life, psychological distress, and communication with healthcare providers), with effect sizes ranging from negligible to large (all ps < .05).

CONCLUSIONS

Social-cognitive theory shows promise as a framework for providing effective person-centred self-management support to patients within this population, and longer-term evaluation is needed.

Association between health literacy and self-care behaviors among patients with chronic kidney disease

BACKGROUND

We explored the association between health literacy and self-care behaviors among low-income patients with chronic kidney disease (CKD).

METHODS

We used baseline data from the Kidney Awareness Registry and Education trial (n = 137 patients with CKD) and multivariable logistic regressions to cross-sectionally examine the association between health literacy, defined by a validated questionnaire, and healthy behaviors.

RESULTS

Study participants had a mean age of 55 years, were racially diverse (6% White, 36% Hispanic, 43% Black, 15% Asian) and 26% had low health literacy. Over one-third (38%) had hypertension, 51% had diabetes, and 67% had CKD stage 3 or 4. Compared to individuals with adequate health literacy, those with low health literacy had non-statistically significant higher tobacco use (adjusted odds ratio [aOR] = 2.33; 95% CI 0.90-6.06) and lower consumption of sugary beverages (aOR = 0.50; 0.20-1.23) and statistically significant decreased fast food intake (aOR = 0.38; 0.16-0.93). Health literacy was not associated with differences in medication adherence (0.84; 0.38-1.89) or physical activity (aOR = 2.39; 0.54-10.53).

CONCLUSIONS

Health literacy was not uniformly associated with all self-care behaviors important for CKD management. A more nuanced understanding of the association of health literacy and self-care may be necessary to promote participation in behaviors known to slow CKD progression.

Black Americans' Perspectives of Barriers and Facilitators of Community Screening for Kidney Disease

BACKGROUND AND OBJECTIVES

Incidence of ESKD is three times higher in black Americans than in whites, and CKD prevalence continues to rise among black Americans. Community-based kidney disease screening may increase early identification and awareness of black Americans at risk, but it is challenging to implement. This study aimed to identify participants' perspectives of community kidney disease screening. The Health Belief Model provides a theoretic framework for conceptualization of these perspectives and optimization of community kidney disease screening activities.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Researchers in collaboration with the Tennessee Kidney Foundation conducted three focus groups of adults in black American churches in Nashville, Tennessee. Questions examined views on CKD information, access to care, and priorities of kidney disease health. Content analysis was used. Guided by the Health Belief Model, a priori themes were generated, and additional themes were derived from the data using an inductive approach.

RESULTS

Thirty-two black Americans completed the study in 2014. Participants were mostly women (79%) with a mean age of 56 years old (range, 24-78). Two major categories of barriers to kidney disease screening were identified: (1) participant factors, including limited kidney disease knowledge, spiritual/religious beliefs, emotions, and culture of the individual; and (2) logistic factors, including lack of convenience and incentives and poor advertisement. Potential facilitators of CKD screening included provision of CKD education, convenience of screening activities, and use of culturally sensitive and enhanced communication strategies. Program recommendations included partnering with trusted community members, selecting convenient locations, tailored advertising, and provision of compensation.

CONCLUSIONS

Findings of this study suggest that provider-delivered culturally sensitive education and stakeholder engagement are critical to increase trust, decrease fear, and maximize participation and early identification of kidney disease among black Americans considering community screening.

Public knowledge of chronic kidney disease evaluated using a validated questionnaire: a cross-sectional study

Background

Screening programs may help to address the burden of chronic kidney disease (CKD) in Australia. Public awareness is an important determinant of the uptake of screening programs. However, data on the public knowledge of CKD in Australia is lacking. The aim of this study was to develop a validated questionnaire and assess the Australian public knowledge of CKD.

Methods

A CKD knowledge questionnaire was developed after reviewing the literature and discussions with nephrology experts. Content validity was performed by nephrologists (n = 3), renal nurses (n = 3) and research personnel (n = 4). The questionnaire was piloted in 121 public participants. Next, discriminant validation was performed by recruiting two additional groups of participants: final year undergraduate pharmacy students (n = 28) and nephrologists (n = 27). Reliability of the questionnaire was assessed by calculating Cronbach’s alpha. Next, a cross-sectional survey of the Australian public (n = 943) was conducted by using the validated questionnaire. It was administered using an online Omnibus survey. Quota sampling was used for participant selection and to ensure that the final sample would match the key characteristics of the Australian population. Finally, a standard multiple regression analysis was performed to identify predictors of the public knowledge.

Results

The median CKD knowledge scores of the public, students and nephrologists were 12, 19 and 23 (maximum score of 24), respectively, with statistically significant differences in the scores across the three groups (p < 0.001; Kruskal-Wallis test). The Cronbach’s alpha was 0.88 (95% CI: 0.86–0.91), indicating that the questionnaire had good internal consistency. In the cross-sectional survey of the Australian public, the participants’ mean (SD) age was 47.6 (±16.6) years and 51.2% were female. The mean (SD) knowledge score was 10.3 (± 5.0). The multivariate analysis showed that participants with a higher level of education; with a family history of kidney failure; with a personal history of diabetes; and currently or previously living in a relationship had significantly higher knowledge scores.

Conclusion

The Australian public knowledge of CKD was relatively poor. Improving public knowledge may assist in increasing early detection and subsequent management of CKD in Australia.

Awareness, self-management behaviors, health literacy and kidney function relationships in specialty practice

AIM

To determine the relationship between chronic kidney disease (CKD) awareness (CKD-A), self-management behaviors (CKD-SMB) knowledge, performance of CKD-SMBs, health literacy (HL) and kidney function.

METHODS

Participants were eligible patients attending an outpatient nephrology clinic. Participants were administered: Newest Vital Sign to measure HL, CKD self-management knowledge tool (CKD-SMKT) to assess knowledge, past performance of CKD-SMB, CKD-A. Estimated GFR (eGFR) was determined using the MDRD-4 equation. Duration of clinic participation and CKD cause were extracted from medical charts.

RESULTS

One-hundred-fifty patients participated in the study. eGFRs ranged from 17-152 mL/min per 1.73 m². Majority (83%) of respondents had stage 3 or 4 CKD, low HL (63%), and were CKD aware (88%). Approximately 40% (10/25) of patients in stages 1 and 2 and 6.4% (8/125) in stages 3 and 4 were unaware of their CKD. CKD-A differed with stage (P < 0.001) but not by HL level, duration of clinic participation, or CKD cause. Majority of respondents (≥ 90%) correctly answered one or more CKD-SMKT items. Knowledge of one behavior, “controlling blood pressure” differed significantly by CKD-A. CKD-A was associated with past performance of two CKD-SMBs, “controlling blood pressure” (P = 0.02), and “keeping healthy body weight” (P = 0.01). Adjusted multivariate analyses between CKD-A and: (1) HL; and (2) CKD-SMB knowledge were non-significant. However, there was a significant relationship between CKD-A and kidney function after controlling for demographics, HL, and CKD-SMB (P < 0.05).

CONCLUSION

CKD-A is not associated with HL, or better CKD-SMBs. CKD-A is significantly associated with kidney function and substantially lower eGFR, suggesting the need for focused patient education in CKD stages 1.

Patient knowledge and adherence to maintenance hemodialysis: an International comparison study

BACKGROUND

Non-adherence to hemodialysis (HD) is associated with increased morbidity and mortality. In this cross-sectional study, we compared correlates and rates of non-adherence between the US and Japan to determine if differences in patient knowledge about HD might account for international variation in adherence.

METHODS

We evaluated 100 US and 116 Japanese patients on maintenance HD. Patient knowledge was scored based on the identification of their vascular access, dry weight, cause of kidney disease, and ≥ 3 phosphorus- and potassium-rich foods. Patients were considered non-adherent if they missed > 3% of HD sessions in 3 months.

RESULTS

23% of the US and none of the Japanese patients were non-adherent. Using logistic regression, we found that in the US non-adherence was more common in black patients [Odds ratio (OR) 3.98; 95% confidence interval (CI) 1.42-11.22], while high school graduates (OR 0.20; 95% CI 0.05-0.81) and those on the transplant waiting list (OR 0.25; 95% CI 0.083-0.72) were less likely to miss their treatments. There was no significant association between knowledge and non-adherence in the US. However, Japanese patients had significantly higher levels of HD knowledge than US patients after adjusting for age (p < 0.001).

CONCLUSION

Age-adjusted HD knowledge was higher and non-adherence rates were lower in Japan vs. the US. However, because of the unexpected finding of 100% adherence in Japan, we were unable to formally test whether knowledge was significantly associated with adherence across both countries. Further research is needed to understand the reasons behind the higher non-adherence rates in the US.

Health Literacy Not Associated with Chronic Kidney Disease Awareness

Background:

Patient awareness of their chronic kidney disease (CKD) and health literacy (HL) are both important for adherence to therapies that slow CKD progression and to reduce risk of complications. Little is known about the association between HL and CKD awareness.

Objective:

We sought to determine if patient HL is associated with CKD awareness.

Methods:

We conducted a cross-sectional study of general medicine inpatients at an urban academic medical center discharged between June 2011 and July 2013 with CKD, defined as having at least one CKD International Classification of Diseases, ninth revision code (585.0–585.9), among their first 20 admission diagnoses. Logistic regression was used to analyze the influence of HL, demographic, clinical, and health care use covariates on the likelihood of patients' CKD awareness. Our primary outcome was patient awareness of their CKD, defined as correct patient self-report of “kidney problems.” We used the Brief Health Literacy Screen, a three-item verbal questionnaire, to assess HL.

Key Results:

Among 1,308 patients with CKD, awareness of CKD was 33%, and 48% had adequate HL. However, CKD awareness was not associated with HL even among patients with stage 4 or 5 CKD. In multivariable logistic regression, greater awareness was associated with being a woman, younger than age 50 years, married, White, having hypertension, and having a higher CKD stage (all p < .05). In stratified analyses, patients with hypertension had greater CKD awareness, regardless of HL or diabetes status (p < .05).

Conclusions:

Among hospitalized patients with CKD, both CKD awareness and HL are low and inadequate. Surprisingly, patients' knowledge of their CKD diagnosis was not related to patients' HL. Patients with hypertension who young, white, or married may be receiving or retaining more education related to CKD. More work is needed on how to effectively communicate CKD diagnosis to prevent widening health disparities. [Health Literacy Research and Practice. 2017;1(3):e117–e127.]

Plain Language Summary:

We studied whether patients with low health literacy also had low awareness of their chronic kidney disease (CKD). Hospitalized patients with CKD were asked three questions about their health literacy and whether they had “kidney problems.” Overall CKD awareness and health literacy were low, but a low score on one did not predict a low score on the other.

A contemporary approach to the prevention of peritoneal dialysis-related peritonitis in children: the role of improvement science

Peritonitis is a leading cause of hospitalizations, morbidity, and modality change in pediatric chronic peritoneal dialysis (CPD) patients. Despite guidelines published by the International Society for Peritoneal Dialysis aimed at reducing the risk of peritonitis, registry data have revealed significant variability in peritonitis rates among centers caring for children on CPD, which suggests variability in practice. Improvement science methods have been used to reduce a variety of healthcare-associated infections and are also being applied successfully to decrease rates of peritonitis in children. A successful quality improvement program with the goal of decreasing peritonitis will not only include primary drivers directly linked to the outcome of peritonitis, but will also direct attention to secondary drivers that are important for the achievement of primary drivers, such as health literacy and patient and family engagement strategies. In this review, we describe a comprehensive improvement science model for the reduction of peritonitis in pediatric patients on CPD.

A Systematic Review of the Prevalence and Associations of Limited Health Literacy in CKD

BACKGROUND AND OBJECTIVES

The self-management and decision-making skills required to manage CKD successfully may be diminished in those with low health literacy. A 2012 review identified five papers reporting the prevalence of limited health literacy in CKD, largely from United States dialysis populations. The literature has expanded considerably since.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We used systematic review, pooled prevalence analysis, metaregression, and exploration of heterogeneity in studies of patients with CKD (all stages).

RESULTS

From 433 studies, 15 new studies met the inclusion criteria and were analyzed together with five studies from the 2012 review. These included 13 cross-sectional surveys, five cohort studies (using baseline data), and two using baseline clinical trial data. Most (19 of 20) were from the United States. In total, 12,324 patients were studied (3529 nondialysis CKD, 5289 dialysis, 2560 transplant, and 946 with unspecified CKD; median =198.5; IQR, 128.5-260 per study). Median prevalence of limited health literacy within studies was 23% (IQR, 16%-33%), and pooled prevalence was 25% (95% confidence interval, 20% to 30%) with significant between-study heterogeneity (I2=97%). Pooled prevalence of limited health literacy was 25% (95% confidence interval, 16% to 33%; I2=97%) among patients with CKD not on dialysis, 27% (95% confidence interval, 19% to 35%; I2=96%) among patients on dialysis, and 14% (95% confidence interval, 7% to 21%; I2=97%) among patients with transplants. A higher proportion of nonwhite participants was associated with increased limited health literacy prevalence (P=0.04), but participant age was not (P=0.40). Within studies, nonwhite ethnicity and low socioeconomic status were consistently and independently associated with limited health literacy. Studies were of low or moderate quality. Within-study participant selection criteria had potential to introduce bias.

CONCLUSIONS

Limited health literacy is common in CKD, especially among individuals with low socioeconomic status and nonwhite ethnicity. This has implications for the design of self-management and decision-making initiatives to promote equity of care and improve quality. Lower prevalence among patients with transplants may reflect selection of patients with higher health literacy for transplantation either because of less comorbidity in this group or as a direct effect of health literacy on access to transplantation.

Development and Validation of the Kidney Transplant Understanding Tool (K-TUT)

BACKGROUND

Several educational interventions have been designed to improve patient knowledge before and after kidney transplantation. However, evaluation of such interventions has been difficult because validated instruments to measure knowledge-based outcomes in this population have not been developed.

OBJECTIVE

To create a tool to measure patient knowledge of kidney transplantation and to evaluate its validity.

METHODS

The Kidney Transplant Understanding Tool (K-TUT) was created using a stepwise iterative process. Experts in the field and transplant recipients were consulted to establish content validity. The K-TUT consists of 9 true/false and 13 multiple-choice questions, and scores are based on the number correct answers [YES/NO format] of 69 items. The questionnaire was piloted in a study that also measured health literacy (via the Short Test of Functional Health Literacy) in transplant candidates, whereas the main survey was mailed to transplant recipients. Test-retest was performed, and completed surveys were analyzed for internal consistency, construct validity, floor and ceiling effects, and reproducibility.

RESULTS

Surveys were offered to 106 pretransplant patients and 235 in the posttransplant period, and response rates were 38.7% (41/106) and 63.4% (149/235), respectively. The mean corrected scores were 53.1 ± 8.5 (77%) and 56.2 ± 6.3 (81%), respectively. Test-retest was performed over 20% of both cohorts and percent agreement ranged between 70% and 100% in the pretransplant group and 66% and 100% in the posttransplant group. Cronbach α ranged from 0.794 to 0.875 in all cohorts indicating favorable internal consistency. Increased health literacy in the pretransplant group was significantly associated with increased knowledge (r = 0.52; P < 0.001), suggestive of construct validity, and the absence of floor and ceiling effects was positive. The majority of transplant recipients (98/148, 67%) believed the questionnaire adequately assessed transplant knowledge, about a quarter (36/148, 24.3%) were "unsure," and 85% (126/148) agreed that no questions should be removed.

CONCLUSIONS

Although more study is warranted to further assess psychometric properties, the K-TUT appears to be a promising tool to measure transplant knowledge.

Gaps and barriers in health-care provision for co-morbid diabetes and chronic kidney disease: a cross-sectional study

BACKGROUND

Patients with diabetes and chronic kidney disease (CKD) are a complex subset of the growing number of patients with diabetes, due to multi-morbidity. Gaps between recommended and received care for diabetes and chronic kidney disease (CKD) are evident despite promulgation of guidelines. Here, we document gaps in tertiary health-care, and the commonest patient-reported barriers to health-care, before exploring the association between these gaps and barriers.

METHODS

This cross-sectional study recruited patients with diabetes and CKD (eGFR < 60 mL/min/1.73 m2) across 4 large hospitals. For each patient, questionnaires were completed examining clinical data, recommended care, and patient-reported barriers limiting health-care. Descriptive statistics, subgroup analyses by CKD stage and hospital, and analyses examining the relationship between health-care gaps and barriers were performed.

RESULTS

308 patients, of mean age 66.9 (SD 11.0) years, and mostly male (69.5%) and having type 2 diabetes (88.0%), participated. 49.1% had stage 3, 24.7% stage 4 and 26.3% stage 5 CKD. Gaps between recommended versus received care were evident: 31.9% of patients had an HbA1c ≥ 8%, and 39.3% had a measured blood pressure ≥ 140/90 mmHg. The commonest barriers were poor continuity of care (49.3%), inadequate understanding/education about CKD (43.5%), and feeling unwell (42.6%). However, barriers associated with a failure to receive items of recommended care were inadequate support from family and friends, conflicting advice from and poor communication amongst specialists, the effect of co-morbidities on self-management and feeling unmotivated (all p < 0.05).

CONCLUSIONS

Barriers to health-care varied across CKD stages and hospitals. Barriers associated with a deviation from recommended care were different for different items of care, suggesting that specific interventions targeting each item of care are required.

A diagnosis of chronic kidney disease: despite fears patients want to know early

Aims: We elicited input from patients on their experience getting a chronic kidney disease (CKD) diagnosis to use for optimizing current CKD education interventions. Methods: We performed structured one-on-one patient interviews. Interviews were recorded, transcribed, and coded using modified grounded theory. Participants had CKD, were not on dialysis, and were recruited from general nephrology practices. Results: 49 patients enrolled from January to October 2014. Interviews revealed four major themes: 1. Reaction to diagnosis – patients described emotional reactions and subsequent behavior changes (152 statements); 2. Timing of diagnosis – patients described how they were told about their diagnosis and expectations of when a person should be told (149 statements); 3. Mediators in diagnosis delivery – patients discussed things that helped or hindered understanding and acceptance of their diagnosis (64 statements), and 4. Perceptions of diagnosis terminology – patients discussed perceptions about diagnostic terms (e.g., “chronic kidney disease”) (91 statements). Cross-sectional study design and setting limit interpretation of causality and generalizability. Conclusions: Patients experience fear but prefer early diagnosis communication. More work is needed to define evidence-based guidelines for diagnosis messaging across the spectrum of care.

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.

A question prompt sheet for adult patients with chronic kidney disease

Background

Patients with chronic kidney disease (CKD) commonly have unmet information needs. Greater patient participation in healthcare discussions can address these needs and improve health outcomes. We developed a patient-centered question prompt sheet (QPS) to engage CKD patients in healthcare conversations.

Methods

We conducted a two phase, mixed-methods, cross-sectional study involving semi-structured telephone interviews. Patients with an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m², on dialysis, or with a kidney transplant were recruited from one Veterans Affairs (VA) nephrology clinic. Phase 1 interviews included open-ended questions assessing patients’ CKD-related information needs and generated a preliminary 67-item QPS. Phase 2 interview participants rated the importance of asking each question on a 5-point Likert scale and provided open-ended feedback. All participants rated their willingness to use a CKD-QPS. Input from patient ratings, a multidisciplinary team, and from members of the National Kidney Disease Education Program (NKDEP) Coordinating Panel helped to shorten and refine the QPS. A qualitative thematic approach was used to analyze open-ended responses. Quantitative data were analyzed for means and proportions.

Results

Eighty-five patients participated. Most were male (97 %), non-Hispanic white (71 %), and mean age was 67 years. Patients desired more information about CKD, particularly dialysis/transplant, and the relationship between CKD and comorbid medical conditions. The final QPS included 31-questions divided into 7 CKD subtopics. Most patients (88 %) reported being ‘completely’ or ‘very’ willing to use a CKD-QPS in future doctor visits.

Conclusions

CKD patients have unmet information needs. We developed a QPS to engage CKD patients in healthcare discussions and to facilitate patient-centered care. Future research should assess whether the CKD-QPS addresses patients’ information needs, enhances doctor-patient communication, and improves health outcomes.

Social Determinants of Racial Disparities in CKD

Significant disparities in CKD rates and outcomes exist between black and white Americans. Health disparities are defined as health differences that adversely affect disadvantaged populations, on the basis of one or more health outcomes. CKD is the complex result of genetic and environmental factors, reflecting the balance of nature and nurture. Social determinants of health have an important role as environmental components, especially for black populations, who are disproportionately disadvantaged. Understanding the social determinants of health and appreciating the underlying differences associated with meaningful clinical outcomes may help nephrologists treat all their patients with CKD in an optimal manner. Altering the social determinants of health, although difficult, may embody important policy and research efforts, with the ultimate goal of improving outcomes for patients with kidney diseases, and minimizing the disparities between groups.

Spanish version of the Kidney Disease Knowledge Survey (KiKS) in Peru: cross-cultural adaptation and validation

INTRODUCTION

Chronic kidney disease (CKD) affects 50 million people globally. Several studies show the importance of implementing interventions that enhance patients’ knowledge about their disease. In 2011 the Kidney Disease Knowledge Survey (KiKS) was developed: a questionnaire that assesses the specific knowledge about chronic kidney disease in pre-dialysis patients.

OBJECTIVE

To translate to Spanish, culturally adapt and validate the Kidney Disease Knowledge Survey questionnaire in a population of patients with pre-dialysis chronic kidney disease.

METHODS

We carried out a Spanish translation and cross-cultural adaptation of the Kidney Disease Knowledge Survey questionnaire. Subsequently, we determined its validity and reliability. We determined the validity through construct validity; and reliability by evaluating its internal consistency and its intra-observer reliability (test-retest).

RESULTS

We found a good internal consistency (Kuder-Richardson = 0.85). The intra-observer reliability was measured by the intra-class correlation coefficient that yielded a value of 0.78 (95% CI: 0.5-1.0). This value indicated a good reproducibility; also, the mean difference of -1.1 test-retest SD 6.0 (p = 0.369) confirms this finding.

CONCLUSION

The translated Spanish version of the Kidney Disease Knowledge Survey is acceptable and equivalent to the original version; it also has a good reliability, validity and reproducibility. Therefore, it can be used in a population of patients with pre-dialysis chronic kidney disease.

Protocol of a randomized controlled trial of an erythropoietin stimulating agent decision aid for anemia treatment in kidney disease

Background

Erythropoiesis-stimulating agents (ESAs) are commonly used for the treatment of anemia due to chronic kidney disease (CKD) and end stage renal disease (ESRD). Patients often lack an understanding of the potential risks and benefits of ESAs, despite government mandated education on this topic. Decision aids are tools commonly used to discuss important information in health care settings. To address this knowledge gap, we designed this study to evaluate the effectiveness of a novel ESA decision aid at promoting informed shared decision making (ISDM) between patients and providers related to ESA use for CKD- and ESRD-related anemia.

Methods

Using the principles of informed shared decision making theory, we designed and piloted an ESA decision aid intended to increase CKD and ESRD patient understanding of the potential risks and benefits of ESAs. Informed by the findings during development, the ESA decision aid was modified and finalized for testing. We will perform a randomized clinical trial to assess if administration of the ESA decision aid improves patient understanding of the risks and benefits of ESA use compared to control patients receiving standard care. Participants with either CKD or ESRD and who are receiving ESAs will be eligible for participation. The primary outcome is patients’ score on the Patient Anemia Knowledge in Kidney Disease (PAKKD) survey assessed at enrollment and 3 months after. Secondary outcomes include decisional conflict related to ESAs, and patient satisfaction with provider communication.

Discussion

The Anemia Risk Communication for patients with Kidney Disease (ARC-KD) study will assess the effectiveness of a novel ESA decision aid to improve patient understanding of ESA use to manage CKD- and ESRD-related anemia. This decision aid is the first resource targeted to improve patient understanding of anemia management in the kidney health context. With the increasing options available for anemia management, this will serve as an important foundation to evolve in the future to optimize anemia-related shared decision making.

Factors associated with knowledge and safety skills of arthritis patients receiving biologics: A survey of 677 patients

OBJECTIVE

We aimed to determine patient and rheumatologist factors associated with the safety skills of patients receiving bDMARDs for inflammatory arthritis.

METHODS

Data were obtained from a descriptive observational cross-sectional nationwide survey performed in 2011 in France. Community- and hospital-based rheumatologists were selected at random. The BioSecure questionnaire was used to collect information on patient safety skills.

RESULTS

Of the 677 patients included (mean age 53±13years old; 452 (67%) women, 411 (61%) had RA; 421 (64%) received subcutaneous bDMARDs). Patients had received information about their treatments from their physician 610 (90%), a nurse 207 (31%), by a written booklet 398 (59%), and/or during therapeutic patient education (TPE) sessions 99 (15%). The median BioSecure total score was 72/100 (IQR 60-82). In total, 99 (16.4%) patients had a low skill level; 321 (53.2%) a moderate skill level and 183 (30.3%) a high skill level. On multivariate regression analysis, as compared with high safety skills, low skills were associated with living alone (OR 2.8 [95% CI 1.3⿿6.0]), low educational level (OR 4.3 [2.1⿿8.9]), living in a large city (OR 3.1 [1.2⿿8.2]), being unemployed (OR 3.3 [1.6⿿6.7]) and not receiving written information, participating in TPE sessions or consulting a nurse (OR 3.8 [1.6⿿8.8]). One rheumatologist-related factor was a high number of patients receiving bDMARDs in the practice.

CONCLUSION

We reveal factors associated with low safety skills of patients receiving bDMARDs for inflammatory arthritis, which should be addressed to improve safety skills in this population.

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.

Relationship between Health Literacy and Kidney Function

AIM

Low health literacy (HL) may contribute to poor self-management of chronic kidney disease (CKD) and poor kidney function. This study aimed to assess the relationship between HL and estimated glomerular filtration rate (eGFR).

METHODS

A cross-sectional observational study was conducted among consecutive eligible adult patients with CKD stages 1-4 attending an outpatient nephrology clinic. HL was assessed using Newest Vital Sign (NVS). eGFR was estimated using the Modification of Diet in Renal Disease equation. CKD self-management behaviour knowledge was assessed using a study instrument (CKD self-management knowledge (SMKT)).

RESULTS

One hundred fifty patients participated in the study (83% participation rate). The prevalence of high likelihood of limited HL was 32.7%. Participants' eGFRs ranged from 17 to 152 mL/min / 1.73 m(2) , with over 80% of the eGFRs below 60 mL/min / 1.73 m(2) . HL was associated with eGFR after controlling for all demographics except age, race and gender (which are included in eGFR equation) (P = 0.05). Every unit increase in NVS score was associated with a 1.9% increase (95% confidence interval = 0 to 3.86%) in eGFR (model R square = 0.23, P = 0.002), which remained significant after controlling for CKD-SMKT (P = 0.05; model R square = 0.28, P < 0.001). The relationship was non-significant after controlling for age, although it remained significant after controlling for other demographics including gender and race.

CONCLUSIONS

There is a small but significant association between HL and eGFR. Providers should use HL-tailored communication strategies in CKD patients. Larger multicentre studies are needed to substantiate this relationship.
