The Kidney Awareness Registry and Education (KARE) study: protocol of a randomized controlled trial to enhance provider and patient engagement with chronic kidney disease

The effect of conscious mindfulness-based informative approaches on managing symptoms in hemodialysis patients

Introduction

The research was conducted to determine the effect of conscious mindfulness based informative approaches applied in hemodialysis patients on reducing stress and managing symptoms.

Methods

This research was conducted as a real experimental model with a control group. Research population consisted of 160 hemodialysis patients. The sample of the study was determined as 120 hemodialysis patients in total, 60 in the experimental and 60 in the control group, as a result of the power analysis. After the pre-test application, a mindfulness-based stress reduction program was applied to the experimental group. In the analysis of the data collected in the research, percentage, frequency, chi-square analysis, t-test for independent groups, t-test for dependent groups were used by means of SPSS for Windows 22.00 statistical software package.

Results

The t-test analyses of the differences between pre-test and post-test scores of hemodialysis patients in the experimental group were found to be significant in favor of the post-tests.

Discussion

It was found out that the conscious mindfulness-based informative approaches decreased the perceived stress and anxiety of the patients in the experimental group, whereas increased their levels of conscious mindfulness and symptom management.

Effectiveness of Multidisciplinary Post-Acute Kidney Injury Clinic on Awareness and Knowledge in Acute Kidney Injury Survivors

INTRODUCTION

Acute kidney injury (AKI) awareness and knowledge among survivors is poor, leading to suboptimal self-management and follow-up care. The purpose of the study was to evaluate the impact of a multidisciplinary post-AKI clinic on AKI awareness and knowledge among survivors.

METHODS

We conducted a quasi-experimental study among stage 2-3 AKI survivors who were followed in the multidisciplinary post-AKI clinic, comprising nephrologists, renal nurses, pharmacists, and dietitians. Patients were evaluated before and after entering the clinic during a 3-month follow-up period, using a three-component questionnaire including the following: (1) Do you know of your AKI diagnosis during hospitalization? (yes/no), (2) how do you rate your AKI knowledge? (ranging from 1 or "very low" to 5 or "excellent"), and (3) 25-item objective AKI knowledge survey instrument that covered general knowledge of AKI, nutrition, medication, and symptoms of renal failure.

RESULTS

A total of 108 AKI survivors were enrolled, with 37.0%, 41.7%, and 21.3% being stage 2 AKI, stage 3 AKI, and stage 3-dialysis AKI, respectively. Before entering the clinic, 50% of patients were unaware of their AKI during hospitalization. After receiving education from the multidisciplinary post-AKI clinic, all patients became aware they had experienced AKI. The mean perceived knowledge and objective knowledge scores were significantly increased over the 3-month period from 1.6 (0.7) to 3.9 (0.7) out of 5 and 15.4 (3.5) to 21.4 (2.0) out of 25, respectively (p < 0.001 for both). Additionally, reverse transformation of the Likert scale to a percentage format also revealed a significant improvement in mean perceived AKI knowledge scores, transitioning from 13.8 ± 16.8 to 73.0 ± 17.6, p < 0.001.

CONCLUSION

The multidisciplinary post-AKI clinic effectively enhanced AKI awareness and knowledge among survivors. These findings highlight the importance of follow-up care and the benefits of a multidisciplinary approach. Further studies are needed to determine the long-term outcomes associated with increased knowledge.

Interventions for improving health literacy in migrants

BACKGROUND

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

OBJECTIVES

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

SEARCH METHODS

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

SELECTION CRITERIA

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

DATA COLLECTION AND ANALYSIS

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

MAIN RESULTS

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

AUTHORS' CONCLUSIONS

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

Controlling Hypertension through Education and Coaching in Kidney Disease (CHECK-D): protocol of a cluster randomised controlled trial

INTRODUCTION

Chronic kidney disease (CKD) affects 30 million Americans. Early management focused on blood pressure (BP) control decreases cardiovascular morbidity and mortality. Less than 40% of patients with CKD achieve recommended BP targets due to many barriers. These barriers include a lack of understanding of the implications of their diagnosis and how to optimise their health.This cluster randomised control trial hypothesises that the combination of early primary care CKD education, and motivational interviewing (MI)-based health coach support, will improve patient behaviours aligned with BP control by increasing patient knowledge, self-efficacy and motivation. The results will aid in sustainable interventions for future patient-centric education and coaching support to improve quality and outcomes in patients with CKD stages 3-5. Outcomes in patients with CKD stages 3-5 receiving the intervention will be compared with similar patients within a control group. Continuous quality improvement (CQI) and systems methodologies will be used to optimise resource neutrality and leverage existing technology to support implementation and future dissemination. The innovative approach of this research focuses on the importance of a multidisciplinary team, including off-site patient coaching, that can intervene early in the CKD care continuum by supporting patients with education and coaching.

METHODS AND ANALYSIS

We will test impact of BP control when clinician-delivered education is followed by 12 months of MI-based health coaching. We will compare outcomes in 350 patients with CKD stages 3-5 between intervention and control groups in primary care. CQI and systems methodologies will optimise education and coaching for future implementation and dissemination.

ETHICS AND DISSEMINATION

This study was approved by the University of Michigan Institutional Review Boards (IRBMED) HUM00136011, HUM00150672 and SITE00000092 and the results of the study will be published on ClinicalTrials.gov, in peer-reviewed journals, as well as conference abstracts, posters and presentations.

Interventions for improving health literacy in people with chronic kidney disease

BACKGROUND

Low health literacy affects 25% of people with chronic kidney disease (CKD) and is associated with increased morbidity and death. Improving health literacy is a recognised priority, but effective interventions are not clear.

OBJECTIVES

This review looked the benefits and harms of interventions for improving health literacy in people with CKD.

SEARCH METHODS

We searched the Cochrane Kidney and Transplant Register of Studies up to 12 July 2022 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. We also searched MEDLINE (OVID) and EMBASE (OVID) for non-randomised studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and non-randomised studies that assessed interventions aimed at improving health literacy in people with CKD.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed studies for eligibility and performed risk of bias analysis. We classified studies as either interventions aimed at improving aspects of health literacy or interventions targeting a population of people with poor health literacy. The interventions were further sub-classified in terms of the type of intervention (educational, self-management training, or educational with self-management training). Results were expressed as mean difference (MD) or standardised mean difference (SMD) with 95% confidence intervals (CI) for continuous outcomes and risk ratios (RR) with 95% CI for dichotomous outcomes.

MAIN RESULTS

We identified 120 studies (21,149 participants) which aimed to improve health literacy. There were 107 RCTs and 13 non-randomised studies. No studies targeted low literacy populations. For the RCTs, selection bias was low or unclear in 94% of studies, performance bias was high in 86% of studies, detection bias was high in 86% of studies reporting subjective outcomes and low in 93% of studies reporting objective outcomes. Attrition and other biases were low or unclear in 86% and 78% of studies, respectively. Compared to usual care, low certainty evidence showed educational interventions may increase kidney-related knowledge (14 RCTs, 2632 participants: SMD 0.99, 95% CI 0.69 to 1.32; I² = 94%). Data for self-care, self-efficacy, quality of life (QoL), death, estimated glomerular filtration rate (eGFR) and hospitalisations could not be pooled or was not reported. Compared to usual care, low-certainty evidence showed self-management interventions may improve self-efficacy (5 RCTs, 417 participants: SMD 0.58, 95% CI 0.13 to 1.03; I² = 74%) and QoL physical component score (3 RCTs, 131 participants: MD 4.02, 95% CI 1.09 to 6.94; I² = 0%). There was moderate-certainty evidence that self-management interventions probably did not slow the decline in eGFR after one year (3 RCTs, 855 participants: MD 1.53 mL/min/1.73 m², 95% CI -1.41 to 4.46; I² = 33%). Data for knowledge, self-care behaviour, death and hospitalisations could not be pooled or was not reported. Compared to usual care, low-certainty evidence showed educational with self-management interventions may increase knowledge (15 RCTs, 2185 participants: SMD 0.65, 95% CI 0.36 to 0.93; I² = 90%), improve self-care behaviour scores (4 RCTs, 913 participants: SMD 0.91, 95% CI 0.00 to 1.82; I² =97%), self-efficacy (8 RCTs, 687 participants: SMD 0.50, 95% CI 0.10 to 0.89; I² = 82%), improve QoL physical component score (3 RCTs, 2771 participants: MD 2.56, 95% CI 1.73 to 3.38; I² = 0%) and may make little or no difference to slowing the decline of eGFR (4 RCTs, 618 participants: MD 4.28 mL/min/1.73 m², 95% CI -0.03 to 8.85; I² = 43%). Moderate-certainty evidence shows educational with self-management interventions probably decreases the risk of death (any cause) (4 RCTs, 2801 participants: RR 0.73, 95% CI 0.53 to 1.02; I² = 0%). Data for hospitalisation could not be pooled.

AUTHORS' CONCLUSIONS

Interventions to improve aspects of health literacy are a very broad category, including educational interventions, self-management interventions and educational with self-management interventions. Overall, this type of health literacy intervention is probably beneficial in this cohort however, due to methodological limitations and high heterogeneity in interventions and outcomes, the evidence is of low certainty.

"Positive Kidney Health": Implementation and design of a pharmacist-led intervention for patients at risk for development or progression of chronic kidney disease

BACKGROUND

Patients with early chronic kidney disease (CKD) or underlying risk factors are often unaware of their kidney test results, common causes of CKD, and ways to lower risk of disease onset/progression.

OBJECTIVE

To test feasibility of a pharmacist-led intervention targeting patient education and risk factors in patients with early CKD and those at risk for CKD.

PRACTICE DESCRIPTION

Ambulatory care pharmacists in community-based primary care clinics delivered kidney health education, ordered labs, and recommended medication adjustments.

PRACTICE INNOVATION

We identified patients with a moderate rate of decline (≥2 mL/min/1.73 m² per year) in estimated glomerular filtration (eGFR) at-risk for CKD or early stage CKD. An interactive workbook was designed to teach patients about kidney test results and self-management of risk factors including hypertension, type 2 diabetes, cigarette smoking, and chronic oral nonsteroidal anti-inflammatory drug use.

EVALUATION METHODS

Outcomes included visit uptake, completion of annual albuminuria screening, and initiation of guideline-directed medications for CKD. Patients were surveyed pre- and post-intervention for kidney health knowledge and perceptions regarding pharmacist-provided information.

RESULTS

Our sample of 20 participants had a mean eGFR of 59 mL/min/1.73 m² and the mean eGFR decline was -4.6 mL/min/1.73 m² per year. There were 47 visits during the pilot period from February 2021 to October 2021. Thirteen patients were missing albuminuria screening within 12 months; 2 of 9 patients with resulting labs had new microalbuminuria and were started on renoprotective medications. Patients had improved understanding of their kidney function test results and most did not consider the information scary or confusing.

CONCLUSION

Barriers to enrollment included fewer participants with multiple risk factors for CKD. The pharmacists were able to engage patients in learning the importance of monitoring and self-management of kidney health. A collaborative practice agreement may enhance a similar intervention that includes initiation of renoprotective medications.

Engagement With a Health Information Technology-Augmented Self-Management Support Program in a Population With Limited English Proficiency: Observational Study

Background

Limited English proficiency (LEP) is an important driver of health disparities. Many successful patient-level interventions to prevent chronic disease progression and complications have used automated telephone self-management support, which relies on patient activation and communication to achieve improved health outcomes. It is not clear whether these interventions are similarly applicable to patients with LEP compared to patients with English proficiency.

Objective

The objectives of this study were as follows: (1) To examine the impact of LEP on patient engagement (primary outcome) with a 12-month language-concordant self-management program that included automated telephone self-management support, designed for patients with chronic kidney disease (CKD). (2) To assess the impact of LEP on change in systolic blood pressure (SBP) and albuminuria (secondary outcomes) resulting from the self-management program.

Methods

This was a secondary analysis of the Kidney Awareness Registry and Education (KARE) pilot trial (NCT01530958) which was funded by the National Institutes of Health in August 2011, approved by the University of California Institutional Review Board in October 2011 (No. 11-07399), and executed between 2013 and 2015. Multivariable logistic and linear models were used to examine various facets of patient engagement with the CKD self-management support program by LEP status. Patient engagement was defined by patient’s use of educational materials, completion of a health coaching action plan, and degree of participation with automated telephone self-management support. Changes in SBP and albuminuria at 12 months by LEP status were determined using multivariable linear mixed models.

Results

Of 137 study participants, 53 (38.7%) reported LEP, of which 45 (85%) were Spanish speaking and 8 (15%) Cantonese speaking. While patients with LEP and English proficiency similarly used the program’s educational materials (85% [17/20] vs 88% [30/34], P=.69) and completed an action plan (81% [22/27] vs 74% [35/47], P=.49), those with LEP engaged more with the automated telephone self-management support component. Average call completion was 66% among patients with LEP compared with 57% among those with English proficiency; patients with LEP requested more health coach telephone calls (P=.08) and had a significantly longer average automated call duration (3.3 [SD 1.4] min vs 2.2 [1.1 min], P<.001), indicating higher patient engagement. Patients with LEP randomized to self-management support had a larger, though nonstatistically significant (P=.74), change in SBP (–4.5 mmHg; 95% CI –9.4 to 0.3) and albuminuria (–72.4 mg/dL; 95% CI –208.9 to 64.1) compared with patients with English proficiency randomized to self-management support (–2.1 mmHg; 95% CI –8.6 to 4.3 and –11.1 mg/dL; 95% CI –166.9 to 144.7).

Conclusions

Patients with LEP with CKD were equally or more engaged with a language-concordant, culturally appropriate telehealth intervention compared with their English-speaking counterparts. Augmented telehealth may be useful in mitigating communication barriers among patients with LEP.

Amplifying the Patient Voice: Key Priorities and Opportunities for Improved Transplant and Living Donor Advocacy and Outcomes During COVID-19 and Beyond

Purpose of Review

To define patient advocacy and engagement for modern transplant and living donation care, particularly in light of the COVID-19 pandemic, describe the patient experience when transplant advocacy and engagement are optimized, and recommend opportunities for advocacy within three key areas: (1) including the patient voice in healthcare decisions and drug development, (2) access to the best evidence-based treatments and informed decision-making, and (3) present and future care innovations and policies.

Recent Findings

There are many avenues for transplant and living donation advocacy and engagement at the patient, provider, family, system, community, and policy levels. Key recommendations include the following: (1) simplifying education to be health literate, written at the appropriate reading level, culturally sensitive, and available in multiple languages and across many delivery platforms, (2) inviting transplant patients and donors to the conversation through advisory panels, consensus conferences, and new mediums like digital storytelling and patient-reported outcomes (PROs), (3) training all members of the health team to understand their role as advocates, and (4) advancing policies and programs that support the financial neutrality of living donation, and support recipients with the cost of immunosuppressive drugs. Key recommendations specific to the COVID-19 pandemic include providing up-to-date, health literate, concise information about preventing COVID-19 and accessing care including telehealth.

Summary

Enhancing advocacy and engagement for transplant patients and donors along the pre-to-post transplant/donation continuum can improve clinical outcomes and quality of life generally, and more so, in light of the COVID-19 pandemic.

An opportunity for improved engagement and transparency: A systematic review of renal dialysis cost effectiveness and discrete choice experiment studies

Much attention is given to patient and provider engagement, cost, and quality. Nephrology is in a unique position to examine the intersection of these issues given kidney dialysis is delivered at a high cost to chronically ill patients. Annual dialysis treatments in Canada range from $56,000-$107,000 per patient dependent on modality. Economists quantify the preferred modality by calculating cost effectiveness through quality-adjusted life years or determining utilization through Discrete Choice Experiments (DCEs). Cost-effectiveness studies identify peritoneal dialysis as the most economical, yet it is the least used. Discrete choice experiments address patient preferences but rarely include cost attributes. This presents a unique paradigm: cost studies do not include patient or physician perspectives, and DCEs do not consider cost. This systematic review of dialysis cost-effectiveness studies and DCEs identifies an opportunity to increase engagement and transparency by involving all care partners in assessing quality and cost.

Interventions to Improve Blood Pressure Control Among Socioeconomically Disadvantaged Patients With CKD: Kidney Awareness Registry and Education Pilot Randomized Controlled Trial

RATIONALE & OBJECTIVE

Sustainable interventions that enhance chronic kidney disease (CKD) management are not often studied in safety-net primary care, in which populations bear a disproportionate burden of disease and experience translational gaps between research and practice. We tested the feasibility of implementing and the impact of 2 technology-enhanced interventions designed to enhance CKD care delivery.

STUDY DESIGN

A 2×2 randomized controlled pilot trial.

SETTING & PARTICIPANTS

Primary care provider teams (n = 6) and 137 patients with CKD aged 18 to 75 years from 2 safety-net primary care clinics, 2013 to 2015.

INTERVENTIONS

Primary care provider teams were randomly assigned to access a CKD registry with point-of-care notifications and quarterly feedback or a usual-care registry for 12 months. Patients within provider teams were randomly assigned to participate in a CKD self-management support program or usual care for 12 months.

OUTCOMES

We examined recruitment, randomization, and participation in each intervention. We also examined the impact of each intervention and their combination on change in systolic blood pressure (SBP), albuminuria, and patient self-reported behavioral measures after 12 months.

RESULTS

Among potentially eligible patients identified using the electronic health record, 24% were eligible for study participation, of whom 35% (n = 137) were enrolled. Mean age was 55 years, 41% were non-English speaking, and 93% were of racial/ethnic minority. Mean baseline estimated glomerular filtration rate was 70.5 (SD = 30.3) mL/min/1.73 m2; mean baseline SBP was 131 (SD = 21.8) mm Hg. Nearly 90% of clinicians reported that the CKD registry influenced their CKD management. More than 95% of patients randomly assigned to CKD self-management support engaged regularly with the intervention. Estimated changes in SBP over 1 year were nonstatistically different in each of the 3 intervention groups compared with usual care: (usual care: 0.5 [95% CI, -5.2 to 6.3] mm Hg; CKD registry only: -5.4 [95% CI, -12.2 to 1.4] mm Hg; CKD self-management support only: -6.4 [95% CI, -13.7 to 1.0] mm Hg; and CKD registry plus CKD self-management support: -0.5 [-5.5 to 4.5] mm Hg), though differences were larger among those with baseline SBPs > 140/90 mm Hg. Decreases in albuminuria were similarly nonstatistically different in each of the intervention groups compared with usual care. No differences were observed in patient self-reported behaviors.

LIMITATIONS

Single health system.

CONCLUSIONS

Patient and provider interventions to improve CKD care are feasible to implement in low-income settings with promising results among those with uncontrolled blood pressure.

Primary care physicians' perceptions of barriers and facilitators to management of chronic kidney disease: A mixed methods study

BACKGROUND

Given the high prevalence of chronic kidney disease (CKD), primary care physicians (PCPs) frequently manage early stage CKD. Nonetheless, there are challenges in providing optimal CKD care in the primary care setting. This study sought to understand PCPs' perceptions of barriers and facilitators to the optimal management of CKD.

STUDY DESIGN

Mixed methods study.

SETTINGS AND PARTICIPANTS

Community-based PCPs in four US cities: Baltimore, MD; St. Louis, MO; Raleigh, NC and San Francisco, CA.

METHODOLOGY

We used a self-administered questionnaire and conducted 4 focus groups of PCPs (n = 8 PCPs/focus group) in each city to identify key barriers and facilitators to management of patients with CKD in primary care.

ANALYTIC APPROACH

We conducted descriptive analyses of the survey data. Major themes were identified from audio-recorded interviews that were transcribed and coded by the research team.

RESULTS

Of 32 participating PCPs, 31 (97%) had been in practice for >10 years, and 29 (91%) practiced in a non-academic setting. PCPs identified multiple barriers to managing CKD in primary care including at the level of the patient (e.g., low awareness of CKD, poor adherence to treatment recommendations), the provider (e.g., staying current with CKD guidelines), and the health care system (e.g., inflexible electronic medical record, limited time and resources). PCPs desired electronic prompts and lab decision support, concise guidelines, and healthcare financing reform to improve CKD care.

CONCLUSIONS

PCPs face substantial but modifiable barriers in providing care to patients with CKD. Interventions that address these barriers and promote facilitative tools may improve PCPs' effectiveness and capacity to care for patients with CKD.

eHealth interventions for people with chronic kidney disease

BACKGROUND

Chronic kidney disease (CKD) is associated with high morbidity and death, which increases as CKD progresses to end-stage kidney disease (ESKD). There has been increasing interest in developing innovative, effective and cost-efficient methods to engage with patient populations and improve health behaviours and outcomes. Worldwide there has been a tremendous increase in the use of technologies, with increasing interest in using eHealth interventions to improve patient access to relevant health information, enhance the quality of healthcare and encourage the adoption of healthy behaviours.

OBJECTIVES

This review aims to evaluate the benefits and harms of using eHealth interventions to change health behaviours in people with CKD.

SEARCH METHODS

We searched the Cochrane Kidney and Transplant Register of Studies up to 14 January 2019 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and quasi-RCTs using an eHealth intervention to promote behaviour change in people with CKD were included. There were no restrictions on outcomes, language or publication type.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial eligibility, extracted data and assessed the risk of bias. The certainty of the evidence was assessed using GRADE.

MAIN RESULTS

We included 43 studies with 6617 participants that evaluated the impact of an eHealth intervention in people with CKD. Included studies were heterogeneous in terms of eHealth modalities employed, type of intervention, CKD population studied and outcomes assessed. The majority of studies (39 studies) were conducted in an adult population, with 16 studies (37%) conducted in those on dialysis, 11 studies (26%) in the pre-dialysis population, 15 studies (35%) in transplant recipients and 1 studies (2%) in transplant candidates We identified six different eHealth modalities including: Telehealth; mobile or tablet application; text or email messages; electronic monitors; internet/websites; and video or DVD. Three studies used a combination of eHealth interventions. Interventions were categorised into six types: educational; reminder systems; self-monitoring; behavioural counselling; clinical decision-aid; and mixed intervention types. We identified 98 outcomes, which were categorised into nine domains: blood pressure (9 studies); biochemical parameters (6 studies); clinical end-points (16 studies); dietary intake (3 studies); quality of life (9 studies); medication adherence (10 studies); behaviour (7 studies); physical activity (1 study); and cost-effectiveness (7 studies).Only three outcomes could be meta-analysed as there was substantial heterogeneity with respect to study population and eHealth modalities utilised. There was found to be a reduction in interdialytic weight gain of 0.13kg (4 studies, 335 participants: MD -0.13, 95% CI -0.28 to 0.01; I² = 0%) and a reduction in dietary sodium intake of 197 mg/day (2 studies, 181 participants: MD -197, 95% CI -540.7 to 146.8; I² = 0%). Both dietary sodium and fluid management outcomes were graded as being of low evidence due to high or unclear risk of bias and indirectness (interdialytic weight gain) and high or unclear risk of bias and imprecision (dietary sodium intake). Three studies reported death (2799 participants, 146 events), with 45 deaths/1000 cases compared to standard care of 61 deaths/1000 cases (RR 0.74, CI 0.53 to 1.03; P = 0.08). We are uncertain whether using eHealth interventions, in addition to usual care, impact on the number of deaths as the certainty of this evidence was graded as low due to high or unclear risk of bias, indirectness and imprecision.

AUTHORS' CONCLUSIONS

eHealth interventions may improve the management of dietary sodium intake and fluid management. However, overall these data suggest that current evidence for the use of eHealth interventions in the CKD population is of low quality, with uncertain effects due to methodological limitations and heterogeneity of eHealth modalities and intervention types. Our review has highlighted the need for robust, high quality research that reports a core (minimum) data set to enable meaningful evaluation of the literature.

Validating laboratory defined chronic kidney disease in the electronic health record for patients in primary care

BACKGROUND

Electronic health record (EHR) data is increasingly used to identify patients with chronic kidney disease (CKD). EHR queries used to capture CKD status, identify comorbid conditions, measure awareness by providers, and track adherence to guideline-concordant processes of care have not been validated.

METHODS

We extracted EHR data for primary-care patients with two eGFRcreat 15-59 mL/min/1.73 m^2 at least 90 days apart. Two nephrologists manually reviewed a random sample of 50 charts to determine CKD status, associated comorbidities, and physician awareness of CKD. We also assessed the documentation of a CKD diagnosis with guideline-driven care.

RESULTS

Complete data were available on 1767 patients with query-defined CKD of whom 822 (47%) had a CKD diagnosis in their chart. Manual chart review confirmed the CKD diagnosis in 34 or 50 (68%) patients. Agreement between the reviewers and the EHR diagnoses on the presence of comorbidities was good (κ > 0.70, p < 0.05), except for congestive heart failure, (κ = 0.45, p < 0.05). Reviewers felt the providers were aware of CKD in 23 of 34 (68%) of the confirmed CKD cases. A CKD diagnosis was associated with higher odds of guideline-driven care including CKD-specific laboratory tests and prescriptions for statins. After adjustment, CKD diagnosis documentation was not significantly associated with ACE/ARB prescription.

CONCLUSIONS

Identifying CKD status by historical eGFRs overestimates disease prevalence. A CKD diagnosis in the patient chart was a reasonable surrogate for provider awareness of disease status, but CKD awareness remains relatively low. CKD in the patient chart was associated with higher rates of albuminuria testing and use of statins, but not use of ACE/ARB.

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.

Impact of a Primary Care CKD Registry in a US Public Safety-Net Health Care Delivery System: A Pragmatic Randomized Trial

BACKGROUND

Many individuals with chronic kidney disease (CKD) do not receive guideline-concordant care. We examined the impact of a team-based primary care CKD registry on clinical measures and processes of care among patients with CKD cared for in a public safety-net health care delivery system.

STUDY DESIGN

Pragmatic trial of a CKD registry versus a usual-care registry for 1 year.

SETTING & PARTICIPANTS

Primary care providers (PCPs) and their patients with CKD in a safety-net primary care setting in San Francisco.

INTERVENTION

The CKD registry identified at point of care all patients with CKD, those with blood pressure (BP)>140/90mmHg, those without angiotensin-converting enzyme (ACE) inhibitor/angiotensin receptor blocker (ARB) prescription, and those without albuminuria quantification in the past year. It also provided quarterly feedback pertinent to these metrics to promote "outreach" to patients with CKD. The usual-care registry provided point-of-care cancer screening and immunization data.

OUTCOMES

Changes in systolic BP at 12 months (primary outcome), proportion of patients with BP control, prescription of ACE inhibitors/ARBs, quantification of albuminuria, severity of albuminuria, and estimated glomerular filtration rate.

RESULTS

The patient population (n=746) had a mean age of 56.7±12.1 (standard deviation) years, was 53% women, and was diverse (8% non-Hispanic white, 35.7% black, 24.5% Hispanic, and 24.4% Asian). Randomization to the CKD registry (30 PCPs, 285 patients) versus the usual-care registry (49 PCPs, 461 patients) was associated with 2-fold greater odds of ACE inhibitor/ARB prescription (adjusted OR, 2.25; 95% CI, 1.45-3.49) and albuminuria quantification (adjusted OR, 2.44; 95% CI, 1.38-4.29) during the 1-year study period. Randomization to the CKD registry was not associated with changes in systolic BP, proportion of patients with uncontrolled BP, or degree of albuminuria or estimated glomerular filtration rate.

LIMITATIONS

Potential misclassification of CKD; missing baseline medication data; limited to study of a public safety-net health care system.

CONCLUSIONS

A team-based safety-net primary care CKD registry did not improve BP parameters, but led to greater albuminuria quantification and more ACE inhibitor/ARB prescriptions after 1 year. Adoption of team-based CKD registries may represent an important step in translating evidence into practice for CKD management.

Role of telehealth in renal replacement therapy education

The prevalence of end-stage renal disease is rising in the United States, which bears high financial and public health burden. The most common modality of renal replacement therapy (RRT) in the United States is in-center hemodialysis. Many patients report lack of comprehensive and timely education about their treatment options, which may preclude them from participating in home-based dialysis therapies and kidney transplantation evaluation. While RRT education has traditionally been provided in-person, the rise of telehealth has afforded new opportunities to improve upon the status quo. For example, technology-augmented RRT education has recently been implemented into telehealth nephrology clinics, informational websites and mobile applications maintained by professional organizations, patient-driven forums on social media, and multimodality programs. The benefits of technology in RRT education are increased access for geographically isolated and/or medically frail patients, versatility of content delivery, information repetition to enhance knowledge retention, and interpersonal connection for educational content and emotional support. Challenges center around privacy and accuracy of information sharing, in addition to differential access to technology due to age and socioeconomic status. A review of available scholarly and social media resources suggests that technology-aided delivery of education about treatment options for end-stage renal disease provides an important alternative and/or supplemental resource for patients and families.

Design of a bilevel clinical trial targeting adherence in heart failure patients and their providers: The Congestive Heart Failure Adherence Redesign Trial (CHART)

BACKGROUND

Socioeconomically disadvantaged patients are at an increased risk for adverse heart failure (HF) outcomes based upon nonadherence to medications and diet. Physicians are also suboptimally adherent to prescribing evidence-based therapy for HF.

METHODS

Congestive Heart Failure Adherence Redesign Trial (CHART) (NCT01698242) is a multicenter, bilevel, cluster randomized behavioral efficacy trial designed to assess the impact of intervening simultaneously on physicians and their socioeconomically disadvantaged patients (annual income <$30,000) having HF with reduced ejection fraction. Treatment arm physicians received individualized feedback on their adherence to prescribing evidence-based therapy. Their patients received weekly home visits from community health workers aimed at promoting understanding of HF and integrating adherence into daily life. Control arm physicians received regular updates on advances in HF management, and patients received monthly HF educational tip sheets produced by the American Heart Association. The primary outcome was all-cause hospital days over 30 months.

RESULTS

A total of 72 physicians (treatment, 35; control, 37) and their 320 patients (treatment, 157; control, 163) were recruited within 2 years. Randomization of physicians with all of their patients being assigned to the same arm was feasible and did not compromise the comparability of patients by arm. Using 5 recruiting hospitals located within disadvantaged neighborhoods produced a cohort that was primarily African American and representative of low-income urban patients with HF with reduced ejection fraction.

CONCLUSION

CHART will determine the value of intervening on low adherence simultaneously in physicians and their socioeconomically disadvantaged patients in reducing all-cause hospitalization days.

Acceptability of a multilevel intervention to improve blood pressure control among patients with chronic kidney disease in a public health care delivery system

Background

The Kidney Awareness Registry and Education (KARE) trial examined the impact of a multilevel intervention on blood pressure control among patients with chronic kidney disease (CKD) in a public health care delivery system. KARE consisted of a clinic-based intervention (a primary care CKD registry with point-of-care provider notifications and quarterly feedback related to CKD management) and a patient-directed intervention [a CKD self-management support (CKD-SMS) program that included low literacy educational materials, automated telephone-administered self-management modules and telephone health coaching]. We explored the acceptability of these interventions among end users.

Methods

At trial conclusion, we surveyed 39 primary care providers (PCPs) to identify preferences about components of the clinic intervention, conducted two focus groups among non-PCP staff to elicit in-depth attitudes and experiences with operationalizing the team-based CKD registry, and conducted eight focus groups with English- and Spanish-speaking patients to hear about their experiences with the CKD-SMS program. Focus group transcripts were analyzed using thematic analysis. Self-reported participation and data from the automated telephone program were used to evaluate patient engagement.

Results

Most PCPs (94%) believed that the point-of-care notifications benefited clinic workflow and agreed that quarterly feedback enhanced their ability to identify (89.5%) and manage (73.7%) CKD. Staff confirmed usefulness of point-of-care notifications. Patients suggested the automated telephone system was impersonal, though easy to use; that frequent automated calls were helpful to reinforce self-management behaviors; and that telephone health coaching was convenient. Nearly 40% of patients completed >80% of automated phone calls, 95% participated in calls with their health coach and 77% created at least one action plan.

Conclusions

A CKD registry is acceptable to primary care health care teams and has potential to enhance identification and management of CKD in primary care. Low-income patients appreciated and engaged with a telephone-based CKD-SMS program, demonstrating its potential for increasing awareness and health engagement among populations with CKD within a public health care delivery system.

Pragmatic Randomized, Controlled Trial of Patient Navigators and Enhanced Personal Health Records in CKD

BACKGROUND AND OBJECTIVES

Patient navigators and enhanced personal health records improve the quality of health care delivered in other disease states. We aimed to develop a navigator program for patients with CKD and an electronic health record-based enhanced personal health record to disseminate CKD stage-specific goals of care and education. We also conducted a pragmatic randomized clinical trial to compare the effect of a navigator program for patients with CKD with enhanced personal health record and compare their combination compared with usual care among patients with CKD stage 3b/4.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Two hundred and nine patients from six outpatient clinics (in both primary care and nephrology settings) were randomized in a 2×2 factorial design into four-study groups: (1) enhanced personal health record only, (2) patient navigator only, (3) both, and (4) usual care (control) group. Primary outcome measure was the change in eGFR over a 2-year follow-up period. Secondary outcome measures included acquisition of appropriate CKD-related laboratory measures, specialty referrals, and hospitalization rates.

RESULTS

Median age of the study population was 68 years old, and 75% were white. At study entry, 54% of patients were followed by nephrologists, and 88% were on renin-angiotensin system blockers. After a 2-year follow-up, rate of decline in eGFR was similar across the four groups (P=0.19). Measurements of CKD-related laboratory parameters were not significantly different among the groups. Furthermore, referral for dialysis education and vascular access placement, emergency room visits, and hospitalization rates were not statistically significant different between the groups.

CONCLUSIONS

We successfully developed a patient navigator program and an enhanced personal health record for the CKD population. However, there were no differences in eGFR decline and other outcomes among the study groups. Larger and long-term studies along with cost-effectiveness analyses are needed to evaluate the role of patient navigators and patient education through an enhanced personal health record in those with CKD.

Adherence to chronic kidney disease guidelines in primary care patients is associated with comorbidity

BACKGROUND

GPs insufficiently follow guidelines regarding consultation and referral for chronic kidney disease (CKD).

OBJECTIVE

To identify patient characteristics and quality of care (QoC) in CKD patients with whom consultation and referral recommendations were not followed.

METHOD

A 14 month prospective observational cohort study of primary care patients with CKD stage 3-5. 47 practices participated, serving 207469 people. 2547 CKD patients fulfilled consultation criteria, 225 fulfilled referral criteria. We compared characteristics of patients managed by GPs with patients receiving nephrologist co-management. We assessed QoC as adherence to monitoring criteria, CKD recognition and achievement of blood pressure (BP) targets.

RESULTS

Patients treated in primary care despite a consultation recommendation (94%) had higher eGFR values (OR 1.07; 95% CI: 1.05-1.09), were less often monitored for renal function (OR 0.42; 95% CI: 0.24-0.74) and potassium (OR 0.56; 95% CI: 0.35-0.92) and CKD was less frequently recognised (OR 0.46; 95% CI: 0.31-0.68) than in patients with nephrologist co-management. Patients treated in primary care despite referral recommendation (70%) were older (OR 1.03; 95% CI:1.01-1.06) and had less cardiovascular disease (OR 0.37; 95% CI: 0.19-0.73). Overall, in patients solely managed by GPs, CKD recognition was 50%, monitoring disease progression in 36% and metabolic parameters in 3%, BP targets were achieved in 51%. Monitoring of renal function and BP was positively associated with diabetes (OR 3.10; 95% CI: 2.47-3.88 and OR 7.78; 95% CI: 3.21-18.87) and hypertension (OR 3.19; 95% CI: 2.67-3.82 and OR 3.35; 95% CI: 1.45-7.77).

CONCLUSION

Patients remaining in primary care despite nephrologists' co-management recommendations were inadequately monitored, and BP targets were insufficiently met. CKD patients without cardiovascular comorbidity or diabetes require extra attention to guarantee adequate monitoring of renal function and BP.

Telehealth Applications to Enhance CKD Knowledge and Awareness Among Patients and Providers

CKD affects 13% of the US adult population, causes excess mortality, and is associated with significant sociodemographic disparities. Optimal CKD management slows progression of disease and reduces cardiovascular-related outcomes. Resources for patients and primary care providers, major stakeholders in preventive CKD care, are critically needed to enhance understanding of the disease and to optimize CKD health, particularly because of the asymptomatic nature of kidney disease. Telehealth is defined as the use of electronic communication and telecommunications technology to support long-distance clinical health care, patient and professional health-related education, and public health and health administration. It provides new opportunities to enhance awareness and understanding among these important stakeholders. This review will examine the role of telehealth within existing educational theories, identify telehealth applications that can enhance CKD knowledge and behavior change among patients and primary care providers, and examine the advantages and disadvantages of telehealth vs usual modalities for education.

Variation in Patients' Awareness of CKD according to How They Are Asked

BACKGROUND AND OBJECTIVES

Awareness of CKD is necessary for patient engagement and adherence to medical regimens. Having an accurate tool to assess awareness is important. Use of the National Health and Nutrition Examination Survey (NHANES) CKD awareness question "Have you ever been told by a doctor or other health professional that you had weak or failing kidneys (excluding kidney stones, bladder infections, or incontinence)?" produces surprisingly low measures of CKD awareness. We sought to compare the sensitivity and specificity of different questions ascertaining awareness of CKD and other health conditions.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Between August of 2011 and August of 2014, an in-person questionnaire was administered to 220 adults with CKD, diabetes, hypertension, or hyperlipidemia who received primary care in a public health care delivery system to ascertain awareness of each condition. CKD awareness was measured using the NHANES question, and other questions, asking if patients knew about their "kidney disease", "protein in the urine", "kidney problem", or "kidney damage." Demographic data were self-reported; health literacy was measured. The sensitivity and specificity of each question was calculated using the medical record as the gold standard.

RESULTS

In this diverse population (9.6% white, 40.6% black, 36.5% Hispanic, 12.3% Asian), the mean age was 58 years, 30% had a non-English language preference, and 45% had low health literacy. Eighty percent of participants had CKD, with a mean eGFR of 47.2 ml/min per 1.73 m(2). The sensitivities of each CKD awareness question were: 26.4% for "kidney damage", 27.7% for "kidney disease", 33.2% for "weak or failing kidneys", 39.8% for "protein in the urine", and 40.1% for "kidney problem." Specificities ranged from 82.2% to 97.6%. The best two-question combination yielded a sensitivity of 53.1% and a specificity of 83.3%. This was lower than awareness of hypertension (90.1%) or diabetes (91.8%).

CONCLUSIONS

CKD awareness is low compared with other chronic diseases regardless of how it is ascertained. Nevertheless, more sensitive questions to ascertain CKD awareness suggest current under-ascertainment.

The next generation of therapeutics for chronic kidney disease

Chronic kidney disease (CKD) represents a leading cause of death in the United States. There is no cure for this disease, with current treatment strategies relying on blood pressure control through blockade of the renin-angiotensin system. Such approaches only delay the development of end-stage kidney disease and can be associated with serious side effects. Recent identification of several novel mechanisms contributing to CKD development - including vascular changes, loss of podocytes and renal epithelial cells, matrix deposition, inflammation and metabolic dysregulation - has revealed new potential therapeutic approaches for CKD. This Review assesses emerging strategies and agents for CKD treatment, highlighting the associated challenges in their clinical development.
