Dementia Care Among United States Dialysis Providers: A Mixed Methods Study Evaluating Clinician Comfort and Knowledge.

Rationale & Objective: Given the high burden of dementia in dialysis patients, the dialysis workforce needs to be prepared to provide high-quality, person-centered dementia care. We explored comfort with and knowledge of dementia among US dialysis care providers. Study Design: Web-based survey. Setting & Participants: Emails were sent to National Kidney Foundation and National Association of Nephrology Technicians/Technologists membership listservs (September 26, 2022-October 22, 2022). In total, 1,121 respondents had complete data for analysis (57%, 35-49 years; 62% female; 62%/22% White/African American) including 81 physicians, 61 advanced practice providers, 230 nurse managers, 260 nurses, 202 social workers, 195 dietitians, and 86 dialysis patient care technicians. Exposures: Provider role, age, tenure, self-reported gender, previous dementia training, and awareness of dementia guidance. Outcomes: Dementia Knowledge (assessed using Dementia Knowledge Assessment Scale [DKAS; score range, 0-25]). Analytic Approach: Characteristics of respondents, comfort with dementia care, and dementia knowledge were summarized and tabulated overall and by role. Robust regression was used to obtain coefficients confidence intervals for the associations between characteristics and DKAS scores, adjusting for role and tenure. Free-text responses to an open-ended question about treating patients with dementia or cognitive impairment were analyzed using thematic analysis. Results: Dementia knowledge among US dialysis providers may be limited (overall DKAS score = 17; range, 13-21 across roles), despite most reporting knowing when patients had dementia (97%) and receiving training in dementia care (62%). Further, training may be inadequate: those who reported receiving dementia training had lower DKAS scores than those who reported not receiving training (ß, -3.9; 95% CI, -4.4 to -3.4). Thematic analysis of open-ended responses suggested that the impact of dementia on dialysis care and management and treatment beyond dialysis care are challenging for providers. Limitations: Data were self-reported and limited information was gathered about quality, content, and timing of dementia training received. Conclusion: Many US dialysis care providers had suboptimal dementia knowledge, despite reporting being comfortable with providing dementia care and reporting they received prior training. Qualitative findings indicate complexity among providers regarding comfort with and knowledge of treating patients with cognitive impairment. Targeted training for the dialysis workforce in dementia knowledge and best practices for person-centered dementia care is warranted.

There is a high burden of mild cognitive impairment and dementia in the US in-center hemodialysis setting. Although the prevalence of dementia is increasing, little is known about the readiness for the interdisciplinary team to provide person-centered, dementia-friendly patient care. Examining data from a US web-based survey, we found that providers felt confident in knowing when a patient had cognitive impairment, but less than two-thirds reported receiving training about dementia. Further, those who received training about dementia or had awareness of dementia guidelines had lower scores for dementia knowledge. This information can be used to develop training and guidance for interdisciplinary team to reduce staff burden and improve quality of care for patients living with cognitive impairment.

Progression of Coronary Artery Calcification and Risk of Clinical Events in CKD: The Chronic Renal Insufficiency Cohort Study.

RATIONALE & OBJECTIVE: Coronary artery calcification (CAC) progresses rapidly in people with chronic kidney disease (CKD) compared with the general population. We studied the association between CAC progression and higher risks of atherosclerotic cardiovascular disease (CVD), congestive heart failure, and all-cause mortality among adults with CKD. STUDY DESIGN: Prospective cohort study. SETTING: & Participants: 1,310 participants in the Chronic Renal Insufficiency Cohort (CRIC) Study who had at least one CAC scan with no prior history of CVD and with observed or imputed data on changes in CAC over time. EXPOSURE: Observed or imputed CAC progression, categorized as incident CAC among participants with zero CAC on the baseline scan, or progressive CAC when the baseline scan demonstrated CAC and there was an increase in CAC ≥50 Agatston units per year. OUTCOMES: Atherosclerotic CVD (myocardial infarction or stroke), congestive heart failure, and all-cause mortality. ANALYTICAL APPROACH: Cause-specific Cox proportional hazards regression, stratified by presence of CAC at baseline. RESULTS: A total of 545 participants without and 765 with prevalent CAC at baseline were included. During a mean 3.3 years between CAC assessments, 177 (32.5%) participants without baseline CAC developed incident CAC while 270 participants (35.3%) with baseline CAC developed a ≥50 Agatston units per year increase in CAC. After multivariable adjustment, incident CAC was associated with 2.42-fold higher rate of atherosclerotic CVD (95% confidence interval [CI]: 1.23-4.79) and 1.82-fold higher rate of all-cause mortality (95% CI: 1.03-3.22). Progressive CAC (≥50 units per year) was not associated with atherosclerotic CVD (hazard ratio [HR]: 1.42; 95% CI: 0.85-2.35) but was associated with a 1.73-fold higher rate of all-cause mortality (95% CI: 1.31-2.28). Progressive CAC was not associated with incident heart failure. LIMITATIONS: Residual confounding and limited statistical power for some outcomes. CONCLUSIONS: Among adults with CKD stages 2-4, CAC progression over a mean 3.3 years was associated with higher risk of atherosclerotic CVD and all-cause mortality. The associations were strongest among participants without CAC at baseline.

Real-Life Experience on the Effect of SGLT2 Inhibitors vs. Finerenone vs. Combination on Albuminuria in Chronic Kidney Disease.

BACKGROUND: There have been several recent advances in the care of patients with chronic kidney disease (CKD), including the use of sodium glucose cotransporter 2 (SGLT2) inhibitors and selective mineralocorticoid receptor antagonists (MRAs). There are very few data reporting the outcomes of these treatments in real-world experience. The aim of this retrospective study is to report the effects of SGLT2 inhibitors, finerenone, and their combination in CKD patients in our community-based setting. METHODS: Ninety-eight patients with CKD with an estimated glomerular filtration rate (eGFR) between 25 and 90 mL/min per 1.73 m2 and a urine albumin-to-creatinine ratio (UACR) ≥ 30 mg/g were included. Patients were divided into three groups: two monotherapy groups of SGLT2 inhibitors or finerenone and a third combination group of therapy with SGLT2 inhibitors for the first 4 months and SGLT2 inhibitors and finerenone subsequently. The primary outcomes were the timing and percentage of patients achieving a >50% reduction in UACR from baseline. RESULTS: Group 1 comprised 52 patients on SGLT2i, group 2 had 22 patients on finerenone, and group 3 had 24 patients on combination therapy. The baseline median UACR and mean eGFR were 513 mg/g and 47.9 mL/min per 1.73 m2 in group 1, 548.0 mg/g and 50.5 mL/min per 1.73 m2 in group 2, and 800 mg/g and 60 mL/min per 1.73 m2 in group 3. At baseline, 71 (72.4%) patients were on the angiotensin-converting enzyme inhibitor (ACEi) or the angiotensin receptor blocker (ARB), and 78 (79.5%) patients had type 2 diabetes. After 8 months of follow-up, a >50% decrease in albuminuria was achieved in 96% of patients in group 3, compared to 50% in group 1 and 59% in group 2 (p-values were <0.01 and <0.01, respectively). There was a statistically but not clinically significant change in mean potassium levels in group 2 (+0.4 mmol/L) compared to either group 1 (0.0 mmol/L with p-value: <0.01) or group 3 (-0.01 mmol/L with p-value: <0.01). However, there was no difference in potassium levels when comparing groups 1 and 3. At the end of the follow-up, the average difference in eGFR was -3.4 (8.8), -5.3(10.1), and -7.8 (11.2) mL/min per 1.73 m2 in groups 1, 2, and 3, respectively, without a statistically significant difference between groups. CONCLUSIONS: In this real-world experience in our community setting, the combination of SGLT2 inhibitors and finerenone in our adult patients with CKD was associated with a very significant and clinically relevant reduction in UACR, without an increased risk of hyperkalemia. Combination therapy of SGLT2 inhibitor and finerenone regarding background use of ACEi/ARB is feasible and should be encouraged for further albuminuria reductions in CKD patients.

Kidney Care in Times of Crises: A Review.

The global burden of kidney disease is increasing, paralleled by a rising number of natural and man-made crises. During these tumultuous times, accessing vital health care resources becomes challenging, posing significant risks to individuals, particularly those with kidney disease. This review delves into the impact of crises on kidney disease, with a particular focus on acute kidney injury (AKI), kidney failure, and kidney transplant. Patients experiencing crush injuries leading to AKI may encounter delayed diagnosis due to the chaotic nature of disasters and limited availability of resources. In chronic crises such as conflicts, patients with kidney failure are particularly affected, and deviations from dialysis standards are unfortunately common, impacting morbidity and mortality rates. Additionally, crises also disrupt access to kidney transplants, potentially compromising transplant outcomes. This review underscores the critical importance of preparedness measures and proactive management for kidney disease in crisis settings. Collaborative efforts among government bodies, rescue teams, health care providers, humanitarian agencies, and nongovernmental organizations are imperative to ensure equitable and reasonable care for kidney disease patients during times of crises, with the aim of saving lives and improving outcomes.

Patient Care Technician Staffing and Outcomes Among US Patients Receiving In-Center Hemodialysis.

Importance: Dialysis patient care technicians (PCTs) play a critical role in US in-center hemodialysis (HD) care, but little is known about the association of PCT staffing with patient outcomes at US HD facilities. Objective: To estimate the associations of in-center HD patient outcomes with facility-level PCT staffing. Design, Setting, and Participants: This was a retrospective cohort study, with data analysis performed from March 2023 to January 2024. Data on US patients with end-stage kidney disease and their treatment facilities were obtained from the US Renal Data System. Participants included patients (aged 18-100 years) initiating in-center HD between January 1, 2016, and December 31, 2018, who continued receiving in-center HD for 90 days or more and had data on PCT staffing at their initial treating HD facility. Exposure: Facility-level patient-to-PCT ratios (number of HD patients divided by the number of PCTs reported by the treating facility in the prior year), categorized into quartiles (highest quartile denotes the highest PCT burden). Main Outcomes and Measures: Patient-level outcomes included 1-year patient mortality, hospitalization, and transplantation. Associations of outcomes with quartile of patient-to-PCT ratio were estimated using incidence rate ratios (IRRs) from mixed-effects Poisson regression, with adjustment for patient demographics and clinical and facility factors. Results: A total of 236 126 patients (mean [SD] age, 63.1 [14.4] years; 135 952 [57.6%] male; 65 945 [27.9%] Black; 37 777 [16.0%] Hispanic; 153 637 [65.1%] White; 16 544 [7.0%] other race; 146 107 [61.9%] with diabetes) were included. After full adjustment, the highest vs lowest quartile of facility-level patient-to-PCT ratio was associated with a 7% higher rate of patient mortality (IRR, 1.07; 95% CI, 1.02-1.12), a 5% higher rate of hospitalization (IRR, 1.05; 95% CI, 1.02-1.08), an 8% lower rate of waitlisting (IRR, 0.92; 95% CI, 0.85-0.98), and a 20% lower rate of transplant (IRR, 0.80; 95% CI, 0.71-0.91). The highest vs lowest quartile of patient-to-PCT ratio was also associated with an 8% higher rate of sepsis-related hospitalization (IRR, 1.08; 95% CI, 1.03-1.14) and a 15% higher rate of vascular access-related hospitalization (IRR, 1.15; 95% CI, 1.03-1.28). Conclusions and Relevance: These findings suggest that initiation of treatment in facilities with the highest patient-to-PCT ratios may be associated with worse early mortality, hospitalization, and transplantation outcomes. These results support further investigation of the impact of US PCT staffing on patient safety and quality of US in-center HD care.

Patient Care Technician Staffing in US Hemodialysis Facilities: An Ecological Study.

Rationale & Objective: Technicians caring for patients receiving dialysis play a critical, frontline role in the care of patients receiving dialysis in the United States. We sought to provide a comprehensive description and identify correlates of US in-center hemodialysis facility patient care technician staffing patterns. Study Design: This was an ecological study. Setting & Participants: US facilities providing hemodialysis and reporting patient care technician staffing, identified using the US Renal Data System. Exposures: Geography, year, and facility characteristics, including aggregated patient characteristics. Outcomes: The study outcome was facility-reported patient-to-patient care technician ratio. Analytical Approach: We examined patient-to-patient care technician ratios by US state and over time and also estimated the differences in patient-to-patient care technician ratios associated with facility characteristics, using robust regression with adjustment for facility-level covariates. Results: The median patient-to-patient care technician ratio among 6,862 US facilities in 2019 was 9.9 (25th-75th percentiles, 8.2-12.0). Median 2019 patient-to-patient care technician ratios varied substantially by US state and region. There was an overall decline (from 10.6 to 9.9) in median patient-to-patient care technician ratios from 2004 to 2019, whereas the percentage of positions that were unfilled increased (from 2.8% to 3.5%). After adjustment, large dialysis organization status (ß, -0.42; 95% CI, -0.61 to -0.23) and larger facility size (ß, -0.51; 95% CI, -0.68 to -0.33) were associated with lower patient-to-patient care technician ratios. Higher patient-to-registered nurse (ß, 0.80; 95% CI, 0.65-0.94) and patient-to-social worker (ß, 0.53; 95% CI, 0.37-0.70) ratios, presence of licensed vocational nurses or licensed practical nurses at the clinic (ß, 0.83; 95% CI, 0.53-1.12), and location in a poverty area (ß, 0.29; 95% CI, 0.13-0.44) were all associated with higher patient-to-patient care technician ratios. Aggregated patient characteristics of patients treated at the facilities were generally not associated with patient-to-patient care technician ratio after adjustment. Limitations: Limited causal inference and potential shifts in staffing after 2019. Conclusions: US dialysis facilities vary considerably in their patient care technician staffing by geography, over time, and by various facility characteristics. Further investigation of US patient care technician staffing is warranted and could lead to better, more stable dialysis staffing, improved staff and patient satisfaction, and higher quality of care.

In the United States, patient care technicians play an important role in hemodialysis care. Although ongoing staffing shortages and turnover among other hemodialysis care providers have been described, little is known about US patient care technician staffing. Examining national data reported by dialysis facilities, we found variability in patient care technician staffing by geography, over time (with fewer patients per patient care technician in more recent years), and by various facility characteristics. This information can be used to target staff recruitment and retention interventions at facilities where patient care technician staffing may be more challenging.

Factors Associated With Non-vaccination for Influenza Among Patients With CKD: Findings From the Chronic Renal Insufficiency Cohort (CRIC) Study.

RATIONALE & OBJECTIVE: Vaccination for influenza is strongly recommended for people with chronic kidney disease (CKD) due to their immunocompromised state. Identifying risk factors for not receiving an influenza vaccine (non-vaccination) could inform strategies for improving vaccine uptake in this high-risk population. STUDY DESIGN: Longitudinal observational study. SETTING & PARTICIPANTS: 3,692 Chronic Renal Insufficiency Cohort Study (CRIC) participants. EXPOSURE: Demographic factors, social determinants of health, clinical conditions, and health behaviors. OUTCOME: Influenza non-vaccination, which was assessed based on a receipt of influenza vaccine ascertained during annual clinic visits in a subset of participants who were under nephrology care. ANALYTICAL APPROACH: Mixed-effects Poisson models to estimate adjusted prevalence ratios (APRs). RESULTS: Between 2009 and 2020, the pooled mean vaccine uptake was 72% (mean age, 66 years; 44% female; 44% Black race). In multivariable models, factors significantly associated with influenza non-vaccination were younger age (APR, 2.16 [95% CI, 1.85-2.52] for<50 vs≥75 years), Black race (APR, 1.58 [95% CI, 1.43-1.75] vs White race), lower education (APR, 1.20 [95% CI, 1.04-1.39 for less than high school vs college graduate]), lower annual household income (APR, 1.26 [95% CI, 1.06-1.49] for <$20,000 vs >$100,000), formerly married status (APR, 1.22 [95% CI, 1.09-1.35] vs currently married), and nonemployed status (APR, 1.13 [95% CI, 1.02-1.24] vs employed). In contrast, participants with diabetes (APR, 0.80 [95% CI, 0.73-0.87] vs no diabetes), chronic obstructive pulmonary disease (COPD) (APR, 0.80 [95% CI, 0.70-0.92] vs no COPD), end-stage kidney disease (APR, 0.64 [0.56 to 0.76] vs estimated glomerular filtration rate≥60mL/min/1.73m2), frailty (APR, 0.86 [95% CI, 0.74-0.99] vs no frailty), and ideal physical activity (APR, 0.90 [95% CI, 0.82-0.99] vs. physically inactive) were less likely to have non-vaccination status. LIMITATIONS: Possible residual confounding. CONCLUSIONS: Among adults with CKD receiving nephrology care, younger adults, Black individuals, and those with adverse social determinants of health were more likely to have the influenza non-vaccination status. Strategies are needed to address these disparities and reduce barriers to vaccination. PLAIN-LANGUAGE SUMMARY: Identifying risk factors for not receiving an influenza vaccine ("non-vaccination") in people living with kidney disease, who are at risk of influenza and its complications, could inform strategies for improving vaccine uptake. In this study, we examined whether demographic factors, social determinants of health, and clinical conditions were linked to the status of not receiving an influenza vaccine among people living with kidney disease and receiving nephrology care. We found that younger adults, Black individuals, and those with adverse social determinants of health were more likely to not receive the influenza vaccine. These findings suggest the need for strategies to address these disparities and reduce barriers to vaccination in people living with kidney disease.

Prime time for chronic kidney disease.

Chronic kidney disease (CKD) represents a public health burden worldwide and is associated with significant morbidity and mortality. Most patients with CKD are managed by primary care practitioners and this educational series hope to improve knowledge and delivery of care to this high-risk patient population with CKD.

Association of Vitamin K Status with Arterial Calcification and Stiffness in Chronic Kidney Disease: The Chronic Renal Insufficiency Cohort.

Background: Arterial calcification and stiffness are common in people with chronic kidney disease (CKD). Higher vitamin K status has been associated with less arterial calcification and stiffness in CKD in cross-sectional studies. Objectives: To determine the association of vitamin K status with coronary artery calcium (CAC) and arterial stiffness [pulse wave velocity (PWV)] at baseline and over 2-4 follow-up years in adults with mild-to-moderate CKD. Methods: Participants (n = 2722) were drawn from the well-characterized Chronic Renal Insufficiency Cohort. Two vitamin K status biomarkers, plasma phylloquinone and plasma dephospho-uncarboxylated matrix gla protein [(dp)ucMGP], were measured at baseline. CAC and PWV were measured at baseline and over 2-4 y of follow-up. Differences across vitamin K status categories in CAC prevalence, incidence, and progression (defined as ≥100 Agatston units/y increase) and PWV at baseline and over follow-up were evaluated using multivariable-adjusted generalized linear models. Results: CAC prevalence, incidence, and progression did not differ across plasma phylloquinone categories. Moreover, CAC prevalence and incidence did not differ according to plasma (dp)ucMGP concentration. Compared with participants with the highest (dp)ucMGP (≥450 pmol/L), those in the middle category (300-449 pmol/L) had a 49% lower rate of CAC progression (incidence rate ratio: 0.51; 95% CI: 0.33, 0.78). However, CAC progression did not differ between those with the lowest (<300 pmol/L) and those with the highest plasma (dp)ucMGP concentration (incidence rate ratio: 0.82; 95% CI: 0.56, 1.19). Neither vitamin K status biomarker was associated with PWV at baseline or longitudinally. Conclusions: Vitamin K status was not consistently associated with CAC or PWV in adults with mild-to-moderate CKD.

Work Experiences of the Interdisciplinary Dialysis Workforce in the United States: A Cross-Sectional Survey.

INTRODUCTION: Suboptimal dialysis care may be in part due to staff issues such as job dissatisfaction, burnout, work overload, high staff turnover, and inconsistent training. Here, we leveraged data collected in a recent national survey to provide an initial, comprehensive description of current work experiences of US dialysis care providers. METHODS: We conducted a cross-sectional survey of 1,240 active US dialysis clinic staff members (physicians, advanced practice providers, nurse managers/clinic coordinators, nurses, social workers, dietitians, and patient care technicians), who were recruited via emails to society membership lists. Respondents were asked about a wide variety of work experiences, including job satisfaction, professional fulfillment, and burnout (Stanford Professional Fulfillment Index), work culture, experiences of hostility and violence, and self-reported medical errors. Responses were summarized overall and compared by clinic role. RESULTS: Most of the survey respondents, representing all 50 US states, were aged 35-49 years (58.3%) or ≥50 years (23.5%), female (60.7%), and white (59.8%; 23.1% black, and 10.0% Asian); 82.1% had been in their current role for at least 1 year. Most US dialysis staff responding to our survey reported being generally satisfied with their jobs (mean rating of 7.9 on 0-10 scale), but only 54.4% met criteria for professional fulfillment, and 32.8% met criteria for burnout, driven by high scores in the work exhaustion domain. Related issues, including high workloads, lack of respect (including experiences of violence and hostility), lack of autonomy, and suboptimal patient environments (in terms of both safety and patient centeredness), were commonly reported among dialysis care providers, although their prevalence often differed by provider type. CONCLUSION: Our results suggest that the dialysis workforce may be at a critical point. Preventing further staff burnout, which could lead to even greater staffing shortages and worse working conditions among those who continue to provide dialysis care, is essential.

Professional Fulfillment, Burnout, and Turnover Intention Among US Dialysis Patient Care Technicians: A National Survey.

RATIONALE & OBJECTIVE: High professional fulfillment and low burnout and staff turnover are necessary for a stable dialysis workforce. We explored professional fulfillment, burnout, and turnover intention among US dialysis patient care technicians (PCTs). STUDY DESIGN: Cross-sectional national survey. SETTING & PARTICIPANTS: National Association of Nephrology Technicians/Technologists (NANT) members in March-May 2022 (N=228; 42.6% aged 35-49 years, 83.9% female, 64.6% White, 85.3% non-Hispanic). EXPOSURE: Likert-scale items (range, 0-4) related to professional fulfillment and 2 domains of burnout (work exhaustion and interpersonal disengagement) and dichotomous items related to turnover intention. ANALYTICAL APPROACH: Summary statistics (percentages, means, medians) were calculated for individual items and average domain scores. Burnout was defined by combined work exhaustion and interpersonal disengagement scores of≥1.3 and professional fulfillment by a score≥3.0. RESULTS: Most respondents (72.8%) worked ≥40 hours per week. Overall scores for work exhaustion, interpersonal disengagement, and professional fulfillment (median [IQR]) were 2.3 (1.3-3.0), 1.0 (0.3-1.8), and 2.6 (2.0-3.2), respectively; 57.5% reported burnout, and 37.3% reported professional fulfillment. Important contributors to burnout and professional fulfillment included salary (66.5%), supervisor support (64.0%), respect from other dialysis staff (57.8%), sense of purpose about work (54.5%), and hours worked per week (52.9%). Only 52.6% reported that they plan to be working as a dialysis PCT in 3 years. Free text responses reinforced perceived excessive work burden and lack of respect. LIMITATIONS: Limited generalizability to all US dialysis PCTs. CONCLUSIONS: More than half of dialysis PCTs reported burnout, driven by work exhaustion; only about one-third reported professional fulfillment. Even among this relatively engaged group of dialysis PCTs, only half intended to continue working as PCTs. Because of the critical, frontline role of dialysis PCTs in the care of patient receiving in-center hemodialysis, strategies to improve morale and reduce turnover are imperative.

Cardiac Structure and Function and Subsequent Kidney Disease Progression in Adults With CKD: The Chronic Renal Insufficiency Cohort (CRIC) Study.

RATIONALE & OBJECTIVE: Heart-kidney crosstalk is recognized as the cardiorenal syndrome. We examined the association of cardiac function and structure with the risk of kidney failure with replacement therapy (KFRT) in a chronic kidney disease (CKD) population. STUDY DESIGN: Prospective observational cohort study. SETTING & PARTICIPANTS: 3,027 participants from the Chronic Renal Insufficiency Cohort Study. EXPOSURE: Five preselected variables that assess different aspects of cardiac structure and function: left ventricular mass index (LVMI), LV volume, left atrial (LA) area, peak tricuspid regurgitation (TR) velocity, and left ventricular ejection fraction (EF) as assessed by echocardiography. OUTCOME: Incident KFRT (primary outcome), and annual estimated glomerular filtration rate (eGFR) slope (secondary outcome). ANALYTICAL APPROACH: Multivariable Cox models and mixed-effects models. RESULTS: The mean age of the participants was 59±11 SD years, 54% were men, and mean eGFR was 43±17mL/min/1.73m2. Between 2003 and 2018 (median follow-up, 9.9 years), 883 participants developed KFRT. Higher LVMI, LV volume, LA area, peak TR velocity, and lower EF were each statistically significantly associated with an increased risk of KFRT, with corresponding HRs for the highest versus lowest quartiles (lowest vs highest for EF) of 1.70 (95% CI, 1.27-2.26), 1.50 (95% CI, 1.19-1.90), 1.43 (95% CI, 1.11-1.84), 1.45 (95% CI, 1.06-1.96), and 1.26 (95% CI, 1.03-1.56), respectively. For the secondary outcome, participants in the highest versus lowest quartiles (lowest vs highest for EF) had a statistically significantly faster eGFR decline, except for LA area (ΔeGFR slope per year, -0.57 [95% CI, -0.68 to-0.46] mL/min/1.73m2 for LVMI, -0.25 [95% CI, -0.35 to-0.15] mL/min/1.73m2 for LV volume, -0.01 [95% CI, -0.12 to-0.01] mL/min/1.73m2 for LA area, -0.42 [95% CI, -0.56 to-0.28] mL/min/1.73m2 for peak TR velocity, and -0.11 [95% CI, -0.20 to-0.01] mL/min/1.73m2 for EF, respectively). LIMITATIONS: The possibility of residual confounding. CONCLUSIONS: Multiple aspects of cardiac structure and function were statistically significantly associated with the risk of KFRT. These findings suggest that cardiac abnormalities and incidence of KFRT are potentially on the same causal pathway related to the interaction between hypertension, heart failure, and coronary artery diseases. PLAIN-LANGUAGE SUMMARY: Heart disease and kidney disease are known to interact with each other. In this study, we examined whether cardiac abnormalities, as assessed by echocardiography, were linked to the subsequent progression of kidney disease among people living with chronic kidney disease (CKD). We found that people with abnormalities in heart structure and function had a greater risk of progression to advanced CKD that required kidney replacement therapy and had a faster rate of decline in kidney function. Our study indicates the potential role of abnormal heart structure and function in the progression of kidney disease among people living with CKD.

Complications Associated with Continuous RRT.

Continuous renal replacement therapy (CRRT) is a form of renal replacement therapy that is used in modern intensive care units (ICUs) to help manage acute kidney injury (AKI), end stage kidney disease (ESKD), poisonings, and some electrolyte disorders. CRRT has transformed the care of patients in the ICU over the past several decades. In this setting, it is important to recognize CRRT-associated complications but also up-to-date management of these complications. Some of these complications are minor, but others may be more significant and even life-threatening. Some CRRT complications may be related to dialysis factors and others to specific patient factors. Our overarching goal in this article is to review and discuss the most significant CRRT-related complications at the different stage of management of CRRT. With the advent of newer solutions, there have been newer complications as well.

Aspirin for Primary and Secondary Prevention of Mortality, Cardiovascular Disease, and Kidney Failure in the Chronic Renal Insufficiency Cohort (CRIC) Study.

Rationale and Objective: Chronic kidney disease is a risk enhancing factor for cardiovascular disease (CVD) and mortality, and the role of aspirin use is unclear in this population. We investigated the risk and benefits of aspirin use in primary and secondary prevention of CVD in the Chronic Renal Insufficiency Cohort Study. Study Design: Prospective observational cohort. Setting & Participants: 3,664 Chronic Renal Insufficiency Cohort participants. Exposure: Aspirin use in patients with and without preexisting CVD. Outcomes: Mortality, composite and individual CVD events (myocardial infarction, stroke, and peripheral arterial disease), kidney failure (dialysis and transplant), and major bleeding. Analytical Approach: Intention-to-treat analysis and multivariable Cox proportional hazards model to examine associations of time varying aspirin use. Results: The primary prevention group was composed of 2,578 (70.3%) individuals. Mean age was 57 ± 11 years, 46% women, 42% Black, and 47% had diabetes. The mean estimated glomerular filtration rate was 45 mL/min/1.73 m2. Median follow-up was 11.5 (IQR, 7.4-13) years. Aspirin was not associated with all-cause mortality in those without preexisting cardiovascular disease (CVD) (HR, 0.84; 95% CI, 0.7-1.01; P = 0.06) or those with CVD (HR, 0.88; 95% CI, 0.77-1.02, P = 0.08). Aspirin was not associated with a reduction of the CVD composite in primary prevention (HR, 0.97; 95% CI, 0.77-1.23; P = 0.79) and in secondary prevention because the original study design was not meant to study the effects of aspirin. Limitations: This is not a randomized controlled trial, and therefore, causality cannot be determined. Conclusions: Aspirin use in chronic kidney disease patients was not associated with reduction in primary or secondary CVD events, progression to kidney failure, or major bleeding.

Treatment Adherence in CKD and Support From Health care Providers: A Qualitative Study.

Rationale & Objective: Adherence to recommended medical treatment is critical in chronic kidney disease (CKD) to prevent complications and progression to kidney failure. Overall adherence to treatment is low in CKD, and as few as 40% of patients with kidney failure receive any documented CKD-related care. The purpose of this study was to explore the experiences of patients with CKD and their adherence to CKD treatment plans, and the role their health care providers played in supporting their adherence. Study Design: One-on-one interviews were conducted in 2019-2020 using a semi-structured interview guide. Participants described experiences with adherence to treatment plans and what they did when experiencing difficulty. Setting & Participants: Participants were recruited from the Chronic Renal Insufficiency Cohort (CRIC) study. All CRIC participants were older than 21 years with CKD stages 2-4; this sample consisted of participants from the University of Pennsylvania CRIC site. Analytical Approach: Interviews were recorded, transcribed, and coded using conventional content analysis. Data were organized into themes using NVivo 12. Results: The sample (n = 32) had a mean age of 67 years, 53% were women, 59% were non-White, with a mean estimated glomerular filtration rate of 56.6 mL/min/1.73 m2. From analysis of factors relevant to treatment planning and adherence, following 4 major themes emerged: patient factors (multiple chronic conditions, motivation, outlook), provider factors (attentiveness, availability/accessibility, communication), treatment planning factors (lack of plan, proactive research, provider-focused treatment goals, and shared decision making), and treatment plan responses (disagreeing with treatment, perceived capability deficit, lack of information, and positive feedback). Limitations: The sample was drawn from the CRIC study, which may not be representative of the general population with CKD. Conclusions: These themes align with Behavioral Learning Theory, which includes concepts of internal antecedents (patient factors), external antecedents (provider factors), behavior (treatment planning factors), and consequences (treatment plan responses). In particular, the treatment plan responses point to innovative potential intervention approaches to support treatment adherence in CKD.

From screening to treatment: the new landscape of diabetic kidney disease.

Globally, diabetes mellitus is the leading cause of chronic kidney disease (CKD), and it is predicted to increase in the following years. Despite its high prevalence, CKD remains under diagnosed. In this BMC Medicine collection of articles on diabetic kidney disease (DKD), we place in context the importance of screening and early detection of DKD and the most accurate tools to monitor for optimal glycemic control in this his risk population. Further, we address this population's risk for severe complications such as stroke and all-cause mortality. We close this editorial by summarizing recent advances in management of this vulnerable population of patients with DKD, including guideline-directed medical therapy, novel treatments, and predictors of treatment failure.
