Centre-level variation in the survival of patients receiving haemodialysis in India: findings from a nationwide private haemodialysis network. THE LANCET REGIONAL HEALTH. SOUTHEAST ASIA 2024; 23:100383. [PMID: 38601176 PMCID: PMC11004392 DOI: 10.1016/j.lansea.2024.100383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Revised: 01/30/2024] [Accepted: 02/26/2024] [Indexed: 04/12/2024]
Abstract
Background There are no large studies examining survival in patients receiving haemodialysis in India or considering centre-level effects on survival. We measured survival variation between dialysis centres across India and evaluated the extent to which differences are explained by measured centre characteristics. Methods This is a multilevel analysis of patient survival in centres of the NephroPlus dialysis network consisting of 193 centres across India. Patients receiving haemodialysis at a centre for ≥90 days between April 2014 and June 2019 were included, with analyses restricted to centres with ≥10 such patients. The primary outcome was all-cause mortality, measured from 90 days after joining a centre. Proportional hazards models with shared frailty were used to model centre- and patient-level effects on survival. Findings Amongst 23,601 patients (median age 53 years; 29% female), the unadjusted centre-specific 180-day Kaplan-Meier survival estimates ranged between 55% (95% confidence interval [CI] 38-80%) and 100%, with a median of 88% (interquartile interval 83%-92%). After accounting for multilevel factors, estimated 180-day survival ranged between 83% (73-89%) and 97% (95-98%), with 90% 180-day survival in the average centre. The mortality rate in patients attending rural centres was 32% (Hazard Ratio 1.32; 95% CI 1.06-1.65) higher than those at urban centres in adjusted analyses. Multiple patient characteristics were associated with mortality. Interpretation This is the first national benchmark for survival amongst dialysis patients in India. Centre- and patient-level characteristics are associated with survival but there remains unexplained variation between centres. As India continues to widen dialysis access, ongoing quality improvement programs will be an important part of ensuring that patients experience the best possible outcomes at the point of care. Funding This project received no external funding.

Interdialytic weight gain and low dialysate sodium concentration in patients on chronic hemodialysis: a systematic review and meta-analysis. Int Urol Nephrol 2024:10.1007/s11255-024-03972-3. [PMID: 38446246 DOI: 10.1007/s11255-024-03972-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 02/02/2024] [Indexed: 03/07/2024]
Abstract
PURPOSE The present systematic review and meta-analysis aimed at evaluating the effect of low dialysate sodium concentration on interdialytic weight gain (IDWG) in chronic hemodialysis patients. METHODS Studies were eligible for inclusion if they were English language papers published in a peer-reviewed journal and met the following inclusion criteria: (1) studies in adult patients (over 18 years of age), (2) included patients on chronic hemodialysis since at least 6 months; (3) compared standard (138-140 mmol/l) or high (> 140 mmol/l) dialysate sodium concentration with low (< 138 mmol/l) dialysate sodium concentration; (4) Included one outcome of interest: interdialytic weight gain. Medline, PubMed, Web of Science, and the Cochrane Library were searched for the quality of reporting for each study was performed using the Quality Assessment Tool of Controlled Intervention Studies of the National Institutes of Health. The quality of reporting of each cross-over study was performed using the Revised Cochrane Risk of Bias (RoB) tool for cross-over trials as proposed by Ding et al. RESULTS: Nineteen studies (710 patients) were included in the analysis: 15 were cross-over and 4 parallel randomized controlled studies. In cross-over studies, pooled analysis revealed that dialysate sodium concentration reduced IDWG with a pooled MD of - 0.40 kg (95% CI - 0.50 to - 0.30; p < 0.001). The systematic review of four parallel, randomized, studies revealed that the use of a low dialysate sodium concentration was associated with a significant reduction of the IDWG in two studies, sustained and almost significant (p = 0.05) reduction in one study, and not significant reduction in one study. CONCLUSION Low dialysate sodium concentration reduces the IDWG in prevalent patients on chronic hemodialysis.

Clinical presentation and outcome of hemodialysis tunneled catheter-related bloodstream infection in older persons. Eur Geriatr Med 2024; 15:235-242. [PMID: 37713092 DOI: 10.1007/s41999-023-00861-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 08/30/2023] [Indexed: 09/16/2023]
Abstract
BACKGROUND The use of a tunneled catheter as the primary vascular access among old hemodialysis patients is frequent. Catheter-related bloodstream infection (CRBSI) is a common complication, associated with increased mortality. Data regarding the clinical presentation and outcomes of CRBSI among old hemodialysis patients is limited. METHODS All chronic hemodialysis patients hospitalized between 2010 and 2022 with CRBSI were included. Patients were classified into two groups: old adults (≥ 75) and younger patients. Clinical, microbiological, and outcome data were collected and analyzed. RESULTS One hundred and fifty-four patients with CRBSI were identified. Fifty-seven were aged ≥ 75 years. Mean age in the older and younger groups was 81.2 ± 5 and 59.7 ± 12.7, respectively. Male gender was predominant (64%). Charlson comorbidity score and Pitt bacteremia score were comparable among both groups. Norton score < 14 was more common among old persons (n = 24, 67% versus n = 21, 31%, p < 0.001), as well as nursing-home residence. Gram-negative pathogens and Staphylococcus aureus were common in both groups. The frequency of inappropriate empirical antimicrobial treatment was higher among older persons. Overall, in-hospital and 90-day mortality was high (age ≥ 75, 36.8%, age < 75, 24.7%, p = 0.14). Age was not significantly associated with mortality after adjustment for low Norton score, residence, and inappropriate antimicrobial therapy as well as resistance patterns of bloodstream isolates [OR = 1.2 (95% CI 0.4-3.3), p = 0.76]. CONCLUSIONS Clinical characteristics and outcomes of CRBSI were comparable among old and young hemodialysis patients. However, the high mortality rate in this cohort suggests that the use of tunneled catheters as a permanent vascular access should be discouraged in both patient groups.

Chhabra R, Davenport A. Is increased subjective thirst associated with greater interdialytic weight gains, extracellular fluid and dietary sodium intake? Artif Organs 2024; 48:91-97.

Abstract
BACKGROUND Some previous studies have reported an effect of increasing subjective thirst and interdialytic weight gains (IDWG), and that this may be influenced by nonadherence to dietary sodium restrictions, whereas others reported no such association. As such we wished to review the effect of self-reported thirst on IDWGs and dietary sodium intake. METHODS Dialysis patients were asked to complete visual analogues thirst, distress thermometer (DT) scores and complete a sodium food frequency questionnaire (SFFQ). IDWG and pre and post dialysis volumes were measured with multifrequency bioelectrical impedance. RESULTS One hundred and eleven patients completed the questionnaires and had bioimpedance measurements: 63% male, mean age 63.8 ± 16.1 years, 33% diabetic with a median thirst score 3 (0-5) and SFFQ 52.0 ± 18, and IDWG 2.1 ± 1.3%. Thirst was associated with DT (r = 0.28, p = 0.004) and negatively with age (r = -0.31, p < 0.001), but not SFFQ, IDWG, extracellular water, or dialysate sodium, or dialysate to plasma gradient. Patients with higher thirst scores were younger (58.0 ± 15.2 vs. 69.4 ± 15.0 years, p < 0.001) with higher DT scores (5 [2-7] vs. 2 [0-5], p < 0.001). On multivariate logistic analysis, only age was associated with self-reported thirst (odds ratio 0.95, 95% confidence limits 0.92-0.98, p < 0.001). CONCLUSION We found that subjective thirst was greater for younger patients and those who reported higher levels of distress, but no association with IDWGs, dietary sodium intake, or dialysate sodium. However, most of our patients followed the dietary advice, as evidenced by the low SFFQ scores and % IDWGs. Whether thirst increases distress or distress increases subjective thirst remains to be determined.

Abstract
Fluid overload, a prevalent complication in patients with renal disease and hypertension, significantly impacts patient morbidity and mortality. The daily clinical challenges that clinicians face include how to identify fluid overload early enough in the course of the disease to prevent adverse outcomes and to guide and potentially reduce the intensity of the diuresis. Traditional methods for evaluating fluid status, such as pitting edema, pulmonary crackles, or chest radiography primarily assess extracellular fluid and do not accurately reflect intravascular volume status or venous congestion. This review explores the rationale, mechanism, and evidence behind more recent methods used to assess volume status, namely, lung ultrasound, inferior vena cava (IVC) ultrasound, venous excess ultrasound score, and basic and advanced cardiac echocardiographic techniques. These methods offer a more accurate and objective assessment of fluid status, providing real-time, non-invasive measures of intravascular volume and venous congestion. The methods we discuss are primarily used in inpatient settings, but, given the increased pervasiveness of ultrasound technology, some could soon expand to the outpatient setting.

Abstract
BACKGROUND AND OBJECTIVES Eight states and Washington, DC have implemented regulations mandating a minimum ratio between treatment staff and patients receiving hemodialysis in a facility in an effort to improve the quality of hemodialysis treatment. Our investigation examines the association between minimum staffing regulations and patient mortality for four states and hospitalizations for two states that implemented these rules during our sample period. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS We utilized a synthetic difference in differences estimation to analyze the effect of minimum staffing ratios on hemodialysis treatment quality, measured by deaths and hospitalizations for end-stage renal disease patients. We used data gathered by the US Renal Data System and aggregated at the state level. RESULTS We are unable to find evidence that mandated dialysis staffing ratios area associated with a reduction in mortality or hospitalizations. We estimate a slight reduction in deaths per 1000 patient hours and a slight increase in hospitalizations, but neither are statistically significant. CONCLUSIONS We were unable to find evidence that minimum staffing ratios for hemodialysis facilities are associated with improved patient outcomes. Our findings highlight the need for future work, studying the impact of these regulations at the facility level.

Abstract
BACKGROUND Good knowledge of and attitudes toward hemodialysis and its complications might be expected to promote good practices and improve adherence. This study investigated, the knowledge, attitude, and practice of patients receiving hemodialysis regarding hemodialysis and its complications. METHODS This cross-sectional study enrolled patients with uremia who were receiving hemodialysis at the Second Affiliated Hospital of Nanjing Medical University (China) between January 9, 2023, and January 16, 2023. A questionnaire was designed that included the following dimensions: demographic/clinical information, knowledge, attitude, and practice. Correlations between knowledge, attitude, and practice scores were evaluated by Pearson correlation analysis. RESULTS The analysis included 493 patients (305 males, 61.87%). The average knowledge, attitude, and practice score was 19.33 ± 7.07 (possible range, 0-31), 28.77 ± 3.58 (possible range, 8-40), and 43.57 ± 6.53 (possible range, 11-55) points, respectively. A higher knowledge score was associated with younger age (P < 0.001), a higher education level (P < 0.001), and not living alone (P < 0.001), while a higher practice score was associated with a shorter history of hemodialysis (P < 0.001). There were positive correlations between the knowledge and practice scores (r = 0.220, P < 0.001) and between the attitude and practice scores (r = 0.453, P < 0.001), although the knowledge and attitude scores were not significantly correlated. CONCLUSIONS The results provide important insights into the knowledge, attitudes, and practices of patients with uremia in Nanjing (China) regarding hemodialysis and its complications. These findings may facilitate education programs to improve self-care practices in patients receiving maintenance hemodialysis in Nanjing (China).

Exploring the influencing factors of unmet palliative care needs in Chinese patients with end-stage renal disease undergoing maintenance hemodialysis: a cross-sectional study. BMC Palliat Care 2023; 22:113. [PMID: 37543565 PMCID: PMC10403855 DOI: 10.1186/s12904-023-01237-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Accepted: 07/29/2023] [Indexed: 08/07/2023] Open
Abstract
BACKGROUND The role of palliative care for end-stage renal disease (ESRD) patients have been proven in some developed countries, but it is still unclear in the mainland of China. In fact, patients with ESRD experience many unmet palliative care needs, such as physical, psychological, social and spiritual needs, but the factors influencing these needs have not investigated. METHODS A cross-sectional study was conducted at two hemodialysis centers in the mainland of China from January to September 2022. Convenience sampling was used to collect data on the participants' socio-demographics, clinical characteristics, the Palliative Care Outcome Scale (POS), the Dialysis Symptom Index (DSI), the Karnofsky Performance Status Scale (KPS), the Patient Health Questionnaire-9 item (PHQ-9), and the Social Support Rate Scale (SSRS). Data were analyzed using latent profile analysis, Kruskal-Wallis test, one-way analysis of variance (ANOVA), the chi-square test and multinomial logistic regression analysis. RESULTS Three hundred five participants were included in this study, and divided palliative care needs into three categories: Class 1, mild palliative care needs (n = 154, 50.5%); Class 2, moderate palliative care needs (n = 89, 29.2%); Class 3, severe palliative care needs (n = 62, 20.3%). Based on the analysis of three profiles, the influencing factors of unmet needs were further analyzed. Compared with Class 3, senior high school education, the household per capita monthly income < 2,000, low KPS scores, high PHQ-9 scores, and low SSRS scores were less likely to be in Class 1 (OR = 0.03, P = 0.012; OR = 0.003, P < 0.001; OR = 1.15, P < 0.001; OR = 0.55, P < 0.001; OR = 1.35, P = 0.002; respectively) and Class 2 (OR = 0.03, P = 0.007; OR = 0.05, P = 0.011; OR = 1.10, P = 0.001; OR = 0.60, P = 0.001; OR = 1.32, P = 0.003; respectively), and high symptom severity were less likely to be in Class 1 (OR = 0.82, P = 0.001). Moreover, compared with Class 1, the household per capita monthly income < 2,000 (OR = 16.41, P < 0.001), high symptom severity scores (OR = 1.12, P = 0.002) and low KPS scores (OR = 0.95, P = 0.002) were more likely to be in Class 2. CONCLUSIONS This study showed that almost half of ESRD patients receiving MHD presented moderate to severe palliative care needs, and the unmet needs were mainly affected by education level, financial pressure, functional status, symptom burden and social support. In the future, it is important to identify the populations with the greatest need for palliative care and consider the influencing factors of unmet needs from a comprehensive perspective, so as to help them improve health-related quality of life.

Abstract
INTRODUCTION According to the US Renal Data System (USRDS), patients with end-stage kidney disease (ESKD) on maintenance dialysis had higher mortality during early COVID-19 pandemic. Less is known about the effect of the pandemic on the delivery of outpatient maintenance hemodialysis and its impact on death. We examined the effect of pandemic-related disruption on the delivery of dialysis treatment and mortality in patients with ESKD receiving maintenance hemodialysis in the Veterans Health Administration (VHA) facilities, the largest integrated national healthcare system in the USA. METHODS Using national VHA electronic health records data, we identified 7,302 Veterans with ESKD who received outpatient maintenance hemodialysis in VHA healthcare facilities during the COVID-19 pandemic (February 1, 2020, to December 31, 2021). We estimated the average change in the number of hemodialysis treatments received and deaths per 1,000 patients per month during the pandemic by conducting interrupted time-series analyses. We used seasonal autoregressive moving average (SARMA) models, in which February 2020 was used as the conditional intercept and months thereafter as conditional slope. The models were adjusted for seasonal variations and trends in rates during the pre-pandemic period (January 1, 2007, to January 31, 2020). RESULTS The number (95% CI) of hemodialysis treatments received per 1,000 patients per month during the pre-pandemic and pandemic periods were 12,670 (12,525-12,796) and 12,865 (12,729-13,002), respectively. Respective all-cause mortality rates (95% CI) were 17.1 (16.7-17.5) and 19.6 (18.5-20.7) per 1,000 patients per month. Findings from SARMA models demonstrate that there was no reduction in the dialysis treatments delivered during the pandemic (rate ratio: 0.999; 95% CI: 0.998-1.001), but there was a 2.3% (95% CI: 1.5-3.1%) increase in mortality. During the pandemic, the non-COVID hospitalization rate was 146 (95% CI: 143-149) per 1,000 patients per month, which was lower than the pre-pandemic rate of 175 (95% CI: 173-176). In contrast, there was evidence of higher use of telephone encounters during the pandemic (3,023; 95% CI: 2,957-3,089), compared with the pre-pandemic rate (1,282; 95% CI: 1,241-1,324). CONCLUSIONS We found no evidence that there was a disruption in the delivery of outpatient maintenance hemodialysis treatment in VHA facilities during the COVID-19 pandemic and that the modest rise in deaths during the pandemic is unlikely to be due to missed dialysis.

Abstract
Hemodynamic complications frequently affect vascular access and are important causes of morbidity and mortality. We present a review of acute complications affecting vascular accesses, focusing on classical and new treatments. Acute complications in hemodialysis vascular access are often underestimated and undertreated, and can present a challenge for both vascular surgeons and anesthesiologists. Accordingly, we considered different anesthesiologic approaches to both hemorrhagic and nonhemorrhagic patients. A strict collaboration among nephrologists, surgeons, and anesthesiologists can potentially improve prevention and management of acute complications and quality of life.

Abstract
Nonadherence to medicines is a global problem compromising health and economic outcomes for individuals and society. This article outlines how adherence is defined and measured, and examines the impact, prevalence and determinants of nonadherence. It also discusses how a psychosocial perspective can inform the development of interventions to optimise adherence and presents a series of recommendations for future research to overcome common limitations associated with the medication nonadherence literature. Nonadherence is best understood in terms of the interactions between an individual and a specific disease/treatment, within a social and environmental context. Adherence is a product of motivation and ability. Motivation comprises conscious decision-making processes but also from more 'instinctive', intuitive and habitual processes. Ability comprises the physical and psychological skills needed to adhere. Both motivation and ability are influenced by environmental and social factors which influence the opportunity to adhere as well as triggers or cues to actions which may be internal (e.g. experiencing symptoms) or external (e.g. receiving a reminder). Systematic reviews of adherence interventions show that effective solutions are elusive, partly because few have a strong theoretical basis. Adherence support targeted at the level of individuals will be more effective if it is tailored to address the specific perceptions (e.g. beliefs about illness and treatment) and practicalities (e.g. capability and resources) influencing individuals' motivation and ability to adhere.

Enhancing the Cardiovascular Safety of Hemodialysis Care Using Multimodal Provider Education and Patient Activation Interventions: Protocol for a Cluster Randomized Controlled Trial. JMIR Res Protoc 2023; 12:e46187.

Abstract
BACKGROUND End-stage kidney disease (ESKD) is treated with dialysis or kidney transplantation, with most patients with ESKD receiving in-center hemodialysis treatment. This life-saving treatment can result in cardiovascular and hemodynamic instability, with the most common form being low blood pressure during the dialysis treatment (intradialytic hypotension [IDH]). IDH is a complication of hemodialysis that can involve symptoms such as fatigue, nausea, cramping, and loss of consciousness. IDH increases risks of cardiovascular disease and ultimately hospitalizations and mortality. Provider-level and patient-level decisions influence the occurrence of IDH; thus, IDH may be preventable in routine hemodialysis care. OBJECTIVE This study aims to evaluate the independent and comparative effectiveness of 2 interventions-one directed at hemodialysis providers and another for patients-in reducing the rate of IDH at hemodialysis facilities. In addition, the study will assess the effects of interventions on secondary patient-centered clinical outcomes and examine factors associated with a successful implementation of the interventions. METHODS This study is a pragmatic, cluster randomized trial to be conducted in 20 hemodialysis facilities in the United States. Hemodialysis facilities will be randomized using a 2 × 2 factorial design, such that 5 sites will receive a multimodal provider education intervention, 5 sites will receive a patient activation intervention, 5 sites will receive both interventions, and 5 sites will receive none of the 2 interventions. The multimodal provider education intervention involved theory-informed team training and the use of a digital, tablet-based checklist to heighten attention to patient clinical factors associated with increased IDH risk. The patient activation intervention involves tablet-based, theory-informed patient education and peer mentoring. Patient outcomes will be monitored during a 12-week baseline period, followed by a 24-week intervention period and a 12-week postintervention follow-up period. The primary outcome of the study is the proportion of treatments with IDH, which will be aggregated at the facility level. Secondary outcomes include patient symptoms, fluid adherence, hemodialysis adherence, quality of life, hospitalizations, and mortality. RESULTS This study is funded by the Patient-Centered Outcomes Research Institute and approved by the University of Michigan Medical School's institutional review board. The study began enrolling patients in January 2023. Initial feasibility data will be available in May 2023. Data collection will conclude in November 2024. CONCLUSIONS The effects of provider and patient education on reducing the proportion of sessions with IDH and improving other patient-centered clinical outcomes will be evaluated, and the findings will be used to inform further improvements in patient care. Improving the stability of hemodialysis sessions is a critical concern for clinicians and patients with ESKD; the interventions targeted to providers and patients are predicted to lead to improvements in patient health and quality of life.

Abstract
BACKGROUND Nonadherence to hemodialysis appointments could potentially result in health complications that can influence morbidity and mortality. We examined the association between different types of inclement weather and hemodialysis appointment adherence. METHODS We analyzed health records of 60,135 patients with kidney failure who received in-center hemodialysis treatment at Fresenius Kidney Care clinics across the Northeastern US counties during 2001-2019. County-level daily meteorological data on rainfall, hurricane and tropical storm events, snowfall, snow depth, and wind speed were extracted using National Oceanic and Atmosphere Agency data sources. A time-stratified case-crossover study design with conditional Poisson regression was used to estimate the effect of inclement weather exposures within the Northeastern US region. We applied a distributed lag nonlinear model framework to evaluate the delayed effect of inclement weather for up to 1 week. RESULTS We observed positive associations between inclement weather and missed appointment (rainfall, hurricane and tropical storm, snowfall, snow depth, and wind advisory) when compared with noninclement weather days. The risk of missed appointments was most pronounced during the day of inclement weather (lag 0) for rainfall (incidence rate ratio [RR], 1.03 per 10-mm rainfall; 95% confidence interval [CI], 1.02 to 1.03) and snowfall (RR, 1.02; 95% CI, 1.01 to 1.02). Over 7 days (lag 0-6), hurricane and tropical storm exposures were associated with a 55% higher risk of missed appointments (RR, 1.55; 95% CI, 1.22 to 1.98). Similarly, 7-day cumulative exposure to sustained wind advisories was associated with 29% higher risk (RR, 1.29; 95% CI, 1.25 to 1.31), while wind gusts advisories showed a 34% higher risk (RR, 1.34; 95% CI, 1.29 to 1.39) of missed appointment. CONCLUSIONS Inclement weather was associated with higher risk of missed hemodialysis appointments within the Northeastern United States. Furthermore, the association between inclement weather and missed hemodialysis appointments persisted for several days, depending on the inclement weather type.

Abstract
Purpose. The purpose of the study was to assess the impact of an educational intervention on the level of knowledge and adherence to the treatment regimen among hemodialysis (HD) patients as well as to describe the association between these variables. Methods. In this randomized controlled trial, 160 HD patients at an HD centre of a 2030-bed tertiary teaching hospital in Southern India were randomly assigned into intervention (N = 80, received education and a booklet) and control (N = 80, received standard care) groups. Knowledge and adherence were measured preintervention and postintervention using a validated questionnaire for knowledge and the ESRD-AQ (End-Stage Renal Disease Questionnaire) for the level of adherence. The statistical analysis of the data was performed with the help of the Statistical Program SPSS version 19.0. The statistical significance level was set at 0.05. Results. The increase in knowledge on disease management, fluid adherence, and dietary adherence in the intervention group was significantly higher compared to the control group. There was no significant correlation between knowledge and adherence. Adherence improved for all the domains, i.e., dialysis attendance, episodes of shortening, adherence to medication, fluid restriction, and dietary restriction. Adherence to fluid and dietary restriction was statistically significant. This trail is registered with https://clinicaltrials.gov/ct2/show/CTRI/2018/05/014166.

Abstract
BACKGROUND Health behaviour adherence is associated with improved survival in kidney failure (KF); however, most patients with KF do not adhere to one or more health behaviours. Existing health behaviour interventions have significant limitations and do not focus on psychological factors that are associated with adherence and health. OBJECTIVES To examine the feasibility, acceptability, and preliminary efficacy of a 12-week, phone-delivered, positive psychology-motivational interviewing (MI) intervention to promote psychological well-being and adherence in KF. DESIGN Single-arm, proof-of-concept trial (N = 10). PARTICIPANTS Participants were adults with KF undergoing haemodialysis and reporting suboptimal adherence to physical activity, diet, and/or medications. Participants attended weekly phone sessions with a study trainer, completed weekly positive psychology exercises (focused on gratitude, strengths, and meaning), and worked towards physical activity, diet, and/or medication goals. MEASUREMENTS Feasibility was measured by the percentage of sessions completed, while acceptability was assessed through participant ratings of positive psychology and MI session ease and utility (0-10 Likert scales). We explored the intervention's impact on psychological outcomes and health behaviour adherence using validated scales and accelerometers. RESULTS Participants completed 78% of sessions and rated the program's components as easy to complete (positive psychology: 8.7 ± 1.5; MI: 8.3 ± 2.0) and subjectively helpful (positive psychology: 8.8 ± 1.2; MI: 8.8 ± 1.6). The intervention led to promising but nonsignificant improvements in psychological and adherence measures. CONCLUSIONS This 12-week, phone-delivered program was feasible, well-accepted, and associated with nonsignificant improvements health behaviour adherence, highlighting the need for a larger efficacy trial.

Abstract
Hyperphosphatemia is an electrolyte disorder highly prevalent in patients with chronic kidney disease undergoing hemodialysis (HD) that usually requires treatment with oral phosphate binders (PBs). Sucroferric oxyhydroxide (SO) is a calcium-free, iron-based PB indicated for the control of serum phosphorus. In the real-world setting, SO has shown clinical effectiveness with a lower pill burden and has also been associated with reduced hospital admission rates. This study aims to assess the potential economic benefits resulting from the introduction of SO to the health-care setting of the Kingdom of Saudi Arabia (KSA). An economic analysis using data from a retrospective real-world study that compared HD patients with uninterrupted SO prescriptions with patients who discontinued SO and switched to other PBs (oPBs). Annual drug costs for the estimated PB-eligible population in KSA were quantified. Costs per responder were estimated for all treatments. Hospital admissions' incidence rates were converted into annual inpatient cost savings and were deducted from drug costs to estimate the annual economic effect of SO versus oPBs. Sensitivity and breakeven analyses were also conducted. The eligible population for PB therapy in KSA was estimated at n = 14,748. Treating therapy-eligible populations exclusively with SO was estimated to generate annual inpatient cost-savings of SAR 107.4-119.4 million compared to treating the population with oPBs. The estimated economic effect signified overall annual savings ranging from SAR 82.8 to SAR 94.8 million when the population is treated with SO. Sensitivity analyses showed persistent cost savings. The estimated benefit-cost ratios showed that for every SAR 1 spent on SO, the expected return on investment was SAR 4.4-4.9. SO is an effective therapy that may result in substantial cost savings from reducing hospital admission costs that are attributable to hyperphosphatemia among HD patients.

Abstract
PURPOSE Little is known about the relationships between apathy, depressive symptoms and interdialytic weight gain (IDWG) in patients on chronic hemodialysis. Aim of the present study is to investigate the association between IDWG and symptoms of depression and apathy in hemodialysis patients. METHODS A total of 139 chronic patients of the HD units between January 2020 and December 2021 were included in the present cross-sectional study. IDWG was calculated as the difference between the pre-HD weight and the weight registered after the previous session; the average of the sessions in a month was registered. Apathy Evaluation Scale (AES) was adopted to evaluate apathy. Depression was assessed by Beck Depression Inventory (BDI). RESULTS Ninety-three patients had IDWG% ≤ 4 and 46 had an IDWG% > 4. Correlation between IDWG% and BDI as well that between IDWG% and AES were not statistically significant. Median BDI and mean AES did not differ significantly between the groups. In addition, 104 patients had a BDI < 16 and 35 had a BDI ≥ 6. Seventy-five patients had an AES score ≤ 35 and 63 had a AES score > 35. The IDWG (kg) and the IDWG% did not differ significantly between the two groups. CONCLUSION IDWG is not associated with symptoms of depression or apathy in hemodialysis patients. Thus, these results may question if the use of behavioral intervention aimed at improving motivation is warranted in the hemodialysis population to reduce the IDWG.

Taylor KS, Umeukeje EM, Santos SR, McNabb KC, Crews DC, Hladek MD. Context Matters: A Qualitative Synthesis of Adherence Literature for People on Hemodialysis. KIDNEY360 2023; 4:41-53. [PMID: 36700903 PMCID: PMC10101575 DOI: 10.34067/kid.0005582022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 11/08/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND Patients with ESKD treated with hemodialysis in the United States have persistently higher rates of nonadherence compared with patients in other developed countries. Nonadherence is associated with an increased risk of death and higher medical expenditure. There is an urgent need to address it with feasible, effective interventions as the prevalence of patients on hemodialysis in the United States continues to grow. However, published adherence interventions demonstrate limited long-term efficacy. METHODS We conducted a synthesis of qualitative studies on adherence to hemodialysis treatment, medications, and fluid and dietary restrictions to identify gaps in published adherence interventions, searching PubMed, CINAHL, PsychInfo, Embase, and Web of Science databases. We analyzed qualitative data with a priori codes derived from the World Health Organization's adherence framework and subsequent codes from thematic analysis. RESULTS We screened 1775 articles and extracted qualitative data from 12. The qualitative data revealed 20 factors unique to hemodialysis across the World Health Organization's five dimensions of adherence. In addition, two overarching themes emerged from the data: (1) adherence in the context of patients' whole lives and (2) dialysis treatment as a double-edged sword. Patient-level factors reflected in the qualitative data extended beyond knowledge about hemodialysis treatment or motivation to adhere to treatment. Patients described a profound grieving process over the loss of their "old self" that impacted adherence. They also navigated complex challenges that could be exacerbated by social determinants of health as they balanced treatment, life tasks, and social roles. CONCLUSIONS This review adds to the growing evidence that one-size-fits-all approaches to improving adherence among patients on hemodialysis are inadequate. Adherence may improve when routine care incorporates patient context and provides ongoing support to patients and families as they navigate the logistical, physical, and psychological hardships of living with dialysis. New research is urgently needed to guide a change in course.

Interdialytic weight gain and educational/cognitive, counseling/behavioral and psychological/affective interventions in patients on chronic hemodialysis: a systematic review and meta-analysis. J Nephrol 2022; 35:1973-1983. [PMID: 36112313 PMCID: PMC9584995 DOI: 10.1007/s40620-022-01450-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Accepted: 08/20/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND This work aimed to shed light on the notorious debate over the role of an educational/cognitive/behavioral or psychological approach in the reduction of interdialytic weight gain (IDWG) in patients on chronic hemodialysis. METHODS Searches were run from 1975 to January 2022 on Medline, PubMed, Web of Science, and the Cochrane Library. The search terms included "hemodialysis/haemodialysis" AND "adherence" AND ("fluid intake" OR "water intake") AND ("weight gain" OR "interdialytic weight gain" OR "IDWG") AND "patient-level interventions. Randomized controlled studies were eligible if they were in English, published in a peer-reviewed journal and regarded adults patients with on chronic hemodialysis for at least 6 months; compared educational/cognitive and/or counseling/behavioral or psychological interventions to no intervention on interdialytic weight gain. Outcome of interest was interdialytic weight gain. The review was registered on the International Prospective Register of Systematic Reviews in Health and Social Care (PROSPERO, ID number CRD42022332401). RESULTS Eighteen studies (1759 patients) were included in the analysis. Compared to the untreated group, educational/cognitive and/or counseling/behavioral interventions significantly reduced interdialytic weight gain with a pooled mean difference of - 0.15 kg (95% CI - 0.26, 30-0.05; P = 0.004). On the other hand, psychological/affective interventions reduced interdialytic weight gain with a pooled mean difference of - 0.26 kg (95% CI - 0.48, - 0.04; P = 0.020). CONCLUSIONS Educational/cognitive, counseling/behavioral or psychological/affective interventions significantly reduced the interdialytic weight gain in patients on chronic hemodialysis, although such reduction did not appear to be clinically relevant on hard outcomes.

Abstract
Background Fluid overload (FO) is a common problem in patients with peritoneal dialysis (PD), it is associated with adverse outcomes and may persist despite adjustements in PD therapy. Objective To evaluate the feasibility and safety of stimulated diaphoresis to reduce FO with the use of a portable sauna bath. Methods Open-label pilot study in patients on continuous ambulatory peritoneal dialysis (CAPD) and FO. The primary outcome was the treatment-related adverse events; secondary outcomes were changes in over-hydration (OH), body weight and blood pressure, FO symptoms, and sleep quality. Dialysis prescription and daily data were recorded. The intervention period consisted in a 30-min, 45°C sauna bath, daily for 10 days, using a portable sauna bath. Results Fifty-one out of 54 total sauna bath sessions were well tolerated. In three (5.5%) sessions adverse effects were reported: transient dizziness in two cases, and a second-degree skin burn in a patient with advanced diabetic neuropathy. OH (6.3 ± 1.2 L vs. 5.5 ± 1.3 L, p = 0.05), body weight (67.7 ± 11.4 vs. 66.8 ± 3.8 kg, p = 0.003), diastolic blood pressure (92 ± 13.5 vs. 83 ± 13.3 mmHg, P = 0.003) and PSQI score (7.3 ± 3.7 vs. 5.1 ± 3.2, p = 0.02) improved significantly between the control and intervention period, respectively. Conclusions Stimulated diaphoresis with a portable sauna bath could be a novel, safe, and effective alternative way to reduce FO in CAPD patients. Larger studies are needed to confirm our results.

Abstract
The Korean Society of Nephrology (KSN) has published a clinical practice guideline (CPG) document for maintenance hemodialysis (HD). The document, 2021 Clinical Practice Guideline on Optimal HD Treatment, is based on an extensive evidence-oriented review of the benefits of preparation, initiation, and maintenance therapy for HD, with the participation of representative experts from the KSN under the methodologists' support for guideline development. It was intended to help clinicians participating in HD treatment make safer and more effective clinical decisions by providing user-friendly guidelines. We hope that this CPG will be meaningful as a recommendation in practice, but not on a regulatory rule basis, as different approaches and treatments may be used by health care providers depending on the individual patient's condition. This CPG consists of eight sections and 15 key questions. Each begins with statements that are graded by the strength of recommendations and quality of the evidence. Each statement is followed by a summary of the evidence supporting the recommendations. There are also a link to full-text documents and lists of the most important reports so that the readers can read further (most of this is available online).

Predictors of Hyperkalemia among Patients on Maintenance Hemodialysis Transported to the Emergency Department by Ambulance. KIDNEY360 2022; 3:615-626. [PMID: 35721611 PMCID: PMC9136889 DOI: 10.34067/kid.0008132021] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/16/2021] [Accepted: 02/01/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Hyperkalemia is common among patients on maintenance hemodialysis (HD) and is associated with mortality. We hypothesized that clinical characteristics available at time of paramedic assessment before emergency department (ED) ambulance transport (ambulance-ED) would associate with severe hyperkalemia (K≥6 mmol/L). Rapid identification of patients who are at risk for hyperkalemia and thereby hyperkalemia-associated complications may allow paramedics to intervene in a timely fashion, including directing emergency transport to dialysis-capable facilities. METHODS Patients on maintenance HD from a single paramedic provider region, who had at least one ambulance-ED and subsequent ED potassium from 2014 to 2018, were examined using multivariable logistic regression to create risk prediction models inclusive of prehospital vital signs, days from last dialysis, and the presence of prehospital electrocardiogram (ECG) features of hyperkalemia. We used bootstrapping with replacement to validate each model internally, and performance was assessed by discrimination and calibration. RESULTS Among 704 ambulance-ED visits, severe hyperkalemia occurred in 75 (11%); 26 patients with ED hyperkalemia did not have a prehospital ECG. Younger age at transport, longer HD vintage, more days from last hemodialysis session (OR=49.84; 95% CI, 7.72 to 321.77 for ≥3 days versus HD the same day [before] ED transport), and prehospital ECG changes (OR=6.64; 95% CI, 2.31 to 19.12) were independently associated with severe ED hyperkalemia. A model incorporating these factors had good discrimination (c-statistic 0.82; 95% CI, 0.76 to 0.89) and, using a cutoff of 25% probability, correctly classified patients 89% of the time. CONCLUSIONS Characteristics available at the time of ambulance-ED were associated with severe ED hyperkalemia. An awareness of these associations may allow health care providers to define novel care pathways to ensure timely diagnosis and management of hyperkalemia.

Abstract
INTRODUCTION This study examined the discordance between hemodialysis patients' reports and their physicians' estimates of dietary restriction adherence and related factors in Japan. METHODS In a cross-sectional survey of 6,644 outpatients, physicians who estimated higher and lower adherence than their patients' self-reported were categorized as overestimation and underestimation in terms of discordance, respectively. Possible factors included clinical indicators, patient characteristics related to negative stereotypes, and health beliefs related to statistical discrimination. RESULTS The concordance rate was .069 based on the weighted kappa coefficient. The coefficients of acceptable serum potassium, prevalence of diabetes, and self-efficacy on overestimates were .663 , -.126, and -.132, respectively. The coefficients of these factors on underestimates were -.589, .338, and .145, respectively. All these coefficients were significant. CONCLUSIONS The discordance may be high and is related to physicians' clinical data reliance, negative stereotypes about patient characteristics, and a lack of understanding of patients' health beliefs.

Abstract
Abstract
Background
Adherence of patients with End-Stage Renal Disease (ESRD) to Hemodialysis (HD), prescribed medications, diet and fluid restrictions is essential to get the desirable outcome and prevent complications. During COVID-19 pandemic, ESRD patients became more concerned with attending the HD sessions and following the protective measures because of the potential for increased susceptibility to COVID-19. The aim of this study was to evaluate the impact of the pandemic on patients' adherence to HD and medical regimens.
Methods
Two hundred five ESRD patients on HD were interviewed with the ESRD Adherence Questionnaire (ESRD-AQ) and the Fear-of-COVID-19 Scale (FCV-19S). Clinical and laboratory correlates of adherence were retrieved from patients' records.
Results
Self-reported adherence to HD showed that 19.5% were not adherent to HD during the pandemic compared to 11.7% before the pandemic (p < 0.001), with a significant agreement with the actual attendance of HD sessions (Kappa = 0.733, p < 0.001). Twenty-five patients (12.2%) had a history of COVID-19. The FCV-19S had a mean score of 18.8 and showed significant positive correlations with the pre-dialysis phosphorus and potassium. Multivariate analysis showed that the main predictors of non-adherence were the history of COVID-19, understanding and perception scores, and the Fear-of-COVID score.
Conclusions
The COVID-19 pandemic adversely affected the adherence of ESRD patients to HD and medical regimen. Strategies to mitigate patients' fears of COVID-19 and improve their understanding and perceptions of adherence to HD and medical regimen should be adopted in HD centers during the pandemic.

Peer mentorship to improve outcomes in patients on hemodialysis (PEER-HD): a randomized controlled trial protocol. BMC Nephrol 2022; 23:92.

Abstract
Abstract
Background
Patients receiving in-center hemodialysis experience disproportionate morbidity and incur high healthcare-related costs. Much of this cost stems from potentially avoidable hospitalizations. Peer mentorship has been used effectively to improve outcomes for patients with complex chronic diseases. We propose testing the efficacy of peer mentorship on hospitalization rates among patients receiving hemodialysis.
Methods
This is a multicenter parallel group randomized controlled pragmatic trial of patients treated at hemodialysis facilities in Bronx, NY and Nashville, TN. The study has two phases. Phase 1 will enroll and train 16 hemodialysis patients (10 in Bronx, NY and 6 in Nashville TN) to be mentors using a program focused on enhancing self-efficacy, dialysis self-management and autonomy-supportive communication skills. Phase 2 will enroll 200 high risk adults receiving hemodialysis (140 in Bronx, NY and 60 in Nashville, TN), half of whom will be randomized to intervention and half to usual care. Intervention participants are assigned to weekly telephone calls with trained mentors (see Phase 1) for a 3-month period.
The primary outcome of Phase 1 will be engagement of mentors with training and change in knowledge scores and autonomy skills from pre- to post-training. The primary outcome of Phase 2 will be the composite count of ED visits and hospitalizations at the end of study follow-up in patient participants assigned to intervention as compared to those assigned to usual care. Secondary outcomes for Phase 2 include the change over the trial period in validated survey scores measuring perception of social support and self-efficacy, and dialysis adherence metrics, among intervention participants as compared to usual care participants.
Discussion
The PEER-HD study will test the feasibility and efficacy of a pragmatic peer-mentorship program designed for patients receiving hemodialysis on ED visit and hospitalization rates. If effective, peer-mentorship holds promise as a scalable patient-centered intervention to decrease hospital resource utilization, and by extension morbidity and cost, for patients receiving maintenance in-center hemodialysis.

Abstract
India's COVID-19 lockdown, one of the most severe in the world, is widely believed to have disrupted critical non-COVID health services. However, linking these disruptions to effects on health outcomes has been difficult due to the lack of reliable, up-to-date health outcomes data. We identified all dialysis patients under a statewide health insurance program in Rajasthan, India (N = 2110), and conducted surveys to examine the effects of the lockdown on non-COVID care access and health outcomes. Post-lockdown mortality was our primary outcome and morbidity and hospitalization were secondary outcomes. 63% of patients experienced a disruption to their care. Transport barriers, hospital service disruptions, and difficulty obtaining medicines were the most common causes. We compared monthly mortality in the four months after the lockdown with pre-lockdown mortality trends, as well as with mortality trends for a similar cohort in the previous year. Mortality in May 2020, after a month of exposure to the lockdown, was 1.70 percentage points (95% CI 0.01–0.03) or 64% higher than in March 2020 and total excess mortality between April and July was estimated to be 22%. A 1SD increase in an index of care disruptions was associated with a 0.17SD (95% CI 0.13–0.22) increase in a morbidity index, a 3.1 percentage point (95% CI 0.012–0.051) increase in hospitalization, and a 2.1 percentage point (95% CI 0.00–0.04) increase in probability of death between May and July. Females, socioeconomically disadvantaged groups, and patients living far from the health system faced worse outcomes. The results highlight the unintended consequences of the lockdown on critical, life-saving non-COVID health services that must be taken into account in the implementation of future policy efforts to control the spread of pandemics. India's nationwide COVID-19 lockdown severely disrupted critical chronic care. Non-COVID-19 morbidity and mortality increased sharply in the subsequent months. Socioeconomically disadvantaged patients were worst affected. Indirect health effects increase the toll of pandemics and worsen health inequality. Pandemic control policies must ensure critical health services continue.

Abstract
RATIONALE & OBJECTIVE Thrice-weekly hemodialysis can result in adequate urea clearance; however, the morbidity and mortality rates of patients treated with maintenance dialysis remain unacceptably high, partly because of nonadherence. African Americans have a higher prevalence of kidney failure treated with dialysis, greater dialysis nonadherence, and higher odds of hospitalization. We hypothesized that more precise ways of assessing dialysis treatment adherence will reflect the severity of nonadherence, distinguish patterns of nonadherence, and inform the design of personalized behavioral interventions. STUDY DESIGN Retrospective cohort study. SETTING & PARTICIPANTS African American patients receiving hemodialysis for >90 days. EXPOSURE Hemodialysis. OUTCOME Dialysis adherence. ANALYTICAL APPROACH Dialysis attendance data were displayed using a dot plot, categorized based on missed and shortened treatments, and examined for patterns. Descriptive characteristics were reported. In an exploratory analysis, associations between dialysis treatment adherence and participant characteristics were evaluated using ordinary least squares regression. An analysis was performed using missed minutes of dialysis and current metrics for measuring dialysis treatment adherence (ie, missed and shortened treatments). RESULTS Among 113 African American patients treated with dialysis, 47% were men; the median age was 57 years (interquartile range, 46-70 years), and the median dialysis vintage was 54 months (interquartile range, 22-90 months). With rows ordered based on the total missed minutes of dialysis, the dot plot displayed a decreasing gradient in the severity of nonadherence, with novel dialysis treatment adherence categories termed as follows: consistent underdialysis, inconsistent dialysis, and consistent dialysis. Distinct patterns of nonadherence and heterogeneity emerged within these categories. Older age was consistently associated with better adherence, as determined by the analyses performed using the total missed minutes of dialysis as well as missed and shortened treatments. LIMITATIONS The study findings, although replicable and paradigm-shifting, might be limited by the short timeline, focus on adherence data specific to African American patients treated with dialysis, and restriction to dialysis units affiliated with 1 academic center. CONCLUSIONS This study presents more precise and novel ways of measuring and displaying dialysis treatment adherence. The findings introduce a more personalized approach for evaluating actual dialysis uptake. Identification of unique patterns of adherence behavior is important to inform the design of effective behavioral interventions and improve outcomes for vulnerable African American patients treated with dialysis.

A Survey on the Current Status of Ophthalmological Consultations in Patients With Diabetes Undergoing Maintenance Hemodialysis and the Effectiveness of Education on Consultation Behavior –Experience of a Single Hemodialysis Clinic in Japan. FRONTIERS IN CLINICAL DIABETES AND HEALTHCARE 2022; 2:827718.

Abstract
IntroductionIt is extremely important for patients with diabetes undergoing maintenance hemodialysis (MHD) to receive regular ophthalmologic examinations. However, even in the field of MHD in Japan, where there are many hemodialysis patients and the survival rate is said to be one of the highest in the world, we often see patients with diabetes who do not receive regular ophthalmologic examinations. In this study, we surveyed the status of ophthalmology consultations and the use of diabetic eye notebook (DEN) among hemodialysis patients with diabetes at hemodialysis clinics to confirm the current situation, with the aim of confirming the effectiveness of education on consultation behavior by medical care staff.Materials and MethodsThis study included 38 diabetic hemodialysis patients attending one MHD clinic in Japan for one year from March 2018 to March 2019. In the first fact-finding survey in March 2018, hemodialysis care unit nurses (HCUNs) in the hemodialysis unit asked the diabetic hemodialysis patients whether they had consulted an ophthalmologist and used the DEN. Based on the results, the HCUNs recommended that hemodialysis patients with complications of diabetes be educated about the usefulness of regular ophthalmologic examinations, even during MHD, and that they use the DEN. This was followed by a second fact-finding survey in March 2019 to reconfirm ophthalmology consultations and DEN use.ResultsRegarding the presence of ophthalmology consultations, 22 of 38 (58%) patients had regular ophthalmology consultations in March 2018, and 27 of 38 (71%) patients had consultations in the following year after receiving information from an HCUN. Only 1 of 22 patients (5%) who consulted the ophthalmologist in March 2018 used a DEN, but 19 of 27 patients (70%) used it the following year.ConclusionIn the future, the development and utilization of a new DEN that includes more detailed patient information, and the spread of self-care guidance to patients by multidisciplinary health care professionals, will increase the consultation rate of MHD patients in Japan and reduce the incidence and progression of ocular diseases in MHD patients.

Hemodial Int 2022; 26:397-407. [PMID: 35037388 PMCID: PMC9543597 DOI: 10.1111/hdi.13006] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 12/27/2021] [Accepted: 12/28/2021] [Indexed: 11/30/2022]
Abstract
Introduction Hyperkalemia (HK), defined as serum potassium (K+) >5.0 mEq/L, is an independent predictor of mortality in patients on maintenance hemodialysis (HD). This study investigated the annual prevalence of HK and examined patient characteristics potentially associated with a higher annual HK prevalence. Methods This retrospective observational cohort study used Dialysis Outcomes and Practice Patterns Study (DOPPS) survey data from US patients undergoing in‐center HD thrice weekly from 2018 to 2019. The primary endpoint was the proportion of patients with any predialysis HK (K+ >5.0 mEq/L) within 1 year from the index date (date of DOPPS enrollment), using the first hyperkalemic K+ value. Secondary endpoints were the proportion of patients with moderate‐to‐severe (K+ >5.5 mEq/L) or severe (K+ >6.0 mEq/L) HK. Findings Overall, 9347 patients on HD were included in this analysis (58% male and 49% aged >66 years). Any predialysis HK (K+ >5.0 mEq/L) occurred in 74% of patients within 1 year of the index date, 52% within 3 months, and 38% within 1 month. The annual prevalence of moderate‐to‐severe and severe HK was 43% and 17%, respectively. Recurrent HK (at least two K+ >5.0 mEq/L within 1 year) occurred in 60% of patients, and 2.8% of patients were prescribed an oral K+ binder. Multivariable logistic regression analysis showed younger age, female sex, Hispanic ethnicity, and renin–angiotensin–aldosterone system inhibitor use were significantly associated with a higher annual prevalence of any predialysis HK, while Black race, obesity, recent initiation of HD, and dialysate K+ bath concentration ≥3 mEq/L were associated with a lower prevalence of HK. Discussion The annual prevalence of predialysis HK and recurrence were high among US patients on HD, whereas oral K+ binder use was low. Further studies are needed to understand the impact of dialysate K+ bath concentrations on predialysis HK among patients on HD.

Abstract
Chronic disease self-management is the establishment and maintenance of behaviors needed to be an active participant in one's health care and experience the best health outcomes. Kidney disease self-management behaviors to slow disease progression include engaging in exercise or physical activity; adhering to a diet low in sodium, potassium, and phosphorus; monitoring laboratory parameters; managing complex medication regimens; coping with disease-related emotional distress; and communicating effectively with providers. Durable behavior change has been difficult to achieve in kidney disease, in part because of an incomplete understanding of the multilevel factors determining chronic disease self-management in this patient group. The biopsychosocial model of chronic illness care posits that an individual's health outcomes result from biological, psychological, social, and environmental factors as part of a multilevel systems hierarchy. Although this theoretical model has been used to comprehensively identify factors driving self-management in other chronic conditions, it has been applied infrequently to behavioral interventions in kidney disease. In this scoping review, we apply the biopsychosocial model of health to identify individual, interpersonal, and systems-level drivers of kidney disease self-management behaviors. We further highlight factors that may serve as novel, impactful targets of theory-based behavioral interventions to understand and sustain behavior change in kidney disease.

Do patients with high versus low treatment and illness burden have different needs? A mixed-methods study of patients living on dialysis. PLoS One 2021; 16:e0260914. [PMID: 34962932 PMCID: PMC8714126 DOI: 10.1371/journal.pone.0260914] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Accepted: 11/21/2021] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Approximately 750,000 people in the U.S. live with end-stage kidney disease (ESKD); the majority receive dialysis. Despite the importance of adherence to dialysis, it remains suboptimal, and one contributor may be patients' insufficient capacity to cope with their treatment and illness burden. However, it is unclear what, if any, differences exist between patients reporting high versus low treatment and illness burden. METHODS We sought to understand these differences using a mixed methods, explanatory sequential design. We enrolled adult patients receiving dialysis, including in-center hemodialysis, home hemodialysis, and peritoneal dialysis. Descriptive patient characteristics were collected. Participants' treatment and illness burden was measured using the Illness Intrusiveness Scale (IIS). Participants scoring in the highest quartile were defined as having high burden, and participants scoring in the lowest quartile as having low burden. Participants in both quartiles were invited to participate in interviews and observations. RESULTS Quantitatively, participants in the high burden group were significantly younger (mean = 48.4 years vs. 68.6 years respectively, p = <0.001). No other quantitative differences were observed. Qualitatively, we found differences in patient self-management practices, such as the high burden group having difficulty establishing a new rhythm of life to cope with dialysis, greater disruption in social roles and self-perception, fewer appraisal focused coping strategies, more difficulty maintaining social networks, and more negatively portrayed experiences early in their dialysis journey. CONCLUSIONS AND RELEVANCE Patients on dialysis reporting the greatest illness and treatment burden have difficulties that their low-burden counterparts do not report, which may be amenable to intervention.

Abstract
Background Poor adherence to scheduled dialysis treatments is common and can cause adverse clinical and economic outcomes. In 2015, the Centers for Medicare and Medicaid Innovation launched the Comprehensive ESRD Care (CEC) Model, a novel modification of the Accountable Care Organization framework. Many model participants reported efforts to increase dialysis adherence and promptly reschedule missed treatments. Methods With Medicare databases covering 2014-2019, we used difference-in-differences models to compare treatment adherence among patients aligned to 1037 CEC facilities relative to those aligned to matched comparison facilities, while accounting for their differences at baseline. Using dates of service, we identified patients who typically received three weekly treatments and the days when treatments typically occurred. Skipped treatments were defined as days when the patient was not hospitalized but did not receive an expected treatment, and rescheduled treatments as days when a patient who had skipped their previous treatment received an additional treatment before their next expected treatment date. Results Patients in the CEC Model had higher odds of attending as-scheduled sessions relative to the comparison group, although the effect was only marginally significant (OR, 1.02; 95% CI, 1.00 to 1.04, P=0.08). Effects were stronger among females (OR, 1.03; 95% CI, 1.00 to 1.06, P=0.06) than males (OR, 1.01; 95% CI, 0.98 to 1.04, P=0.49), and among those aged <70 years (OR, 1.02; 95% CI, 1.00 to 1.05, P=0.04) than those aged ≥70 years (OR, 1.00; 95% CI, 0.96 to 1.04, P=0.96). The CEC was associated with higher odds of rescheduled sessions (OR, 1.09; 95% CI, 1.05 to 1.14, P<0.001). Effects were significant for both sexes, but were larger among males (OR, 1.11; 95% CI, 1.05 to 1.18, P<0.001) than females (OR, 1.07; 95% CI, 1.02 to 1.13, P=0.01), and effects were significant among those <70 years (OR, 1.12; 95% CI, 1.07 to 1.17, P<0.001), but not those ≥70 years (OR, 0.99; 95% CI, 0.92 to 1.07, P=0.80). Conclusions The CEC Model is intended to incentivize strategies to prevent costly interventions. Because poor dialysis adherence may precipitate hospitalizations or other adverse events, many CEC Model participants encouraged adherence and promptly rescheduled missed treatments as strategic priorities. This study suggests these efforts were a success, although the absolute magnitudes of the effects were modest.

Abstract
The Korean Society of Nephrology (KSN) has published a clinical practice guideline (CPG) document for maintenance hemodialysis (HD). The document, 2021 Clinical Practice Guideline on Optimal HD Treatment, is based on an extensive evidence-oriented review of the benefits of preparation, initiation, and maintenance therapy for HD, with the participation of representative experts from the KSN under the methodologists’ support for guideline development. It was intended to help clinicians participating in HD treatment make safer and more effective clinical decisions by providing user-friendly guidelines. We hope that this CPG will be meaningful as a recommendation in practice, but not on a regulatory rule basis, as different approaches and treatments may be used by health care providers depending on the individual patient’s condition. This CPG consists of eight sections and 15 key questions. Each begins with statements that are graded by the strength of recommendations and quality of the evidence. Each statement is followed by a summary of the evidence supporting the recommendations. There is also a link to full-text documents and lists of the most important reports so that the readers can read further (most of this is available online).

Vijay VR, Kang HK. The worldwide prevalence of non-adherence to diet and fluid restrictions among hemodialysis patients: A systematic review and meta-analysis. J Ren Nutr 2021; 32:658-669. [PMID: 34923113 DOI: 10.1053/j.jrn.2021.11.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 11/16/2021] [Accepted: 11/28/2021] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Non-adherence to diet and fluid restrictions in hemodialysis (HD) patients can lead to undesired health outcomes. This systematic review and meta-analysis aim to estimate the pooled prevalence of non-adherence to diet and fluid restrictions in HD patients. METHODS Research papers from PubMed, CINAHL, and Google Scholar on non-adherence to diet and fluid restrictions in HD patients published between 2000 and 2020 were selected for this study. The methodological quality of each study was graded, and the estimates were pooled using the random-effects model of meta-analysis. Analyses of subgroups and meta-regression were carried out. Egger's test and visual analysis of the symmetry of funnel plots were used to assess the publication bias. RESULTS Eight hundred sixty-eight potential records were identified during the search. Twenty-three studies that met inclusion criteria were considered for meta-analysis and comprised 11,209 HD patients (mean age 55.85 years± SD 6.86, males 57.74%). The estimated worldwide prevalence of non-adherence to diet and fluid restrictions was 60.2% (95% CI: 47.3- 72.5) and 60.6% (95% CI: 50- 70.7), respectively. The meta-regression found that the income category was negatively, and the risk of bias score was positively associated with the prevalence of non-adherence to fluid restrictions (p<0.05). The funnel plot of studies included pooling the prevalence of non-adherence to fluid restrictions revealed asymmetry, and a significant publication bias was also noted as assessed by Egger's test (P = 0.004). However, the pooled estimate should be interpreted with caution because the prevalence of individual studies varies considerably due to methodological or measurement discrepancies. CONCLUSION The pooled prevalence of non-adherence to diet (47.3 - 72.5%) and fluid (50 - 70.7%) restrictions were substantially high. The health care team must recognize the factors and barriers influencing adherence behavior and develop holistic interventions to improve it.

Prevalence of fluid overload in an urban US hemodialysis population: A cross-sectional study. Hemodial Int 2021; 26:264-273. [PMID: 34897937 DOI: 10.1111/hdi.12986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 08/25/2021] [Accepted: 11/30/2021] [Indexed: 10/19/2022]
Abstract
INTRODUCTION Inadequate fluid status remains a key driver of cardiovascular morbidity and mortality in chronic hemodialysis (HD) patients. Quantification of fluid overload (FO) using bioimpedance spectroscopy (BIS) has become standard in many countries. To date, no BIS device has been approved in the United States for fluid status assessment in kidney patients. Therefore, no previous quantification of fluid status in US kidney patients using BIS has been reported. Our aim was to conduct a cross-sectional BIS-based assessment of fluid status in an urban US HD population. METHODS We determined fluid status in chronic HD patients using whole body BIS (Body Composition Monitor, BCM). The BCM reports FO in liters; negative FO denotes fluid depletion. Measurements were performed before dialysis. Post-HD FO was estimated by subtracting the intradialytic weight loss from the pre-HD FO. FINDINGS We studied 170 urban HD patients (age 61 ± 14 years, 60% male). Pre- and post-HD FO (mean ± SD), were 2.2 ± 2.4 and -0.2 ± 2.7 L, respectively. Pre-HD, 43% of patients were fluid overloaded, 53% normally hydrated, and 4% fluid depleted. Post-HD, 12% were fluid overloaded, 55% normohydrated and 32% fluid depleted. Only 48% of fluid overloaded patients were hypertensive, while 38% were normotensive and 14% hypotensive. Fluid status did not differ significantly between African Americans (N = 90) and Caucasians (N = 61). DISCUSSION While about half of the patients had normal fluid status pre-HD, a considerable proportion of patients was either fluid overloaded or depleted, indicating the need for tools to objectively quantify fluid status.

Kim H, Cho MK. Factors Influencing Self-Care Behavior and Treatment Adherence in Hemodialysis Patients. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182412934. [PMID: 34948543 PMCID: PMC8701178 DOI: 10.3390/ijerph182412934] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 11/28/2021] [Accepted: 12/06/2021] [Indexed: 12/03/2022]
Abstract
Low self-care and treatment adherence are found among hemodialysis patients. We aimed to identify the factors influencing self-care behavior and treatment adherence and examine the mediating effect of treatment adherence on self-care behavior. A questionnaire was administered through a social media community from 11 July to 13 August 2021. The data collected from 100 participants were analyzed using the independent t-test, one-way analysis of variance, Pearson’s correlation, multiple linear regression analysis, and hierarchical multiple regression analysis. The mean self-care behavior and treatment adherence scores were 3.52 ± 0.57 and 4.01 ± 0.48, respectively. The mean age and hemodialysis duration were 51.70 ± 9.40 and 7.57 ± 7.21 years, respectively. The common primary cause of end-stage renal disease was glomerulonephritis (n = 39, 39%). Self-care behavior varied with education, frequency of self-care behavior education, and social support and was positively correlated with treatment adherence and social support. Treatment adherence was positively correlated with social support. Treatment adherence, social support, and health status were influenced self-care behavior (54.5%. Self-care behavior and frequency of self-care behavior education influenced treatment adherence (61.3%). Treatment adherence partially mediated the relationship between social support and self-care behavior. Intervention strategies that increase both social support and treatment adherence can promote self-care behavior.

Abstract
BACKGROUND Cost-related medication nonadherence (CRMNA) refers to not taking medications as prescribed because of difficulties paying for them. OBJECTIVES The aims of this study were (1) to assess the prevalence of CRMNA to immunosuppressants in heart transplant recipients internationally and (2) to determine multilevel correlates (patient, center, and healthcare system levels) of CRMNA. METHODS Using data from the cross-sectional international BRIGHT study, applying multistaged sampling, CRMNA was assessed via 3 self-report items in 1365 patients from 36 heart transplant centers in 11 countries. Cost-related medication nonadherence was defined as any positive answer on any of the 3 items. Healthcare system-level (ie, insurance coverage, out-of-pocket expenditures) and patient-level (ie, intention, perceived financial burden, cost as a barrier, a health belief regarding medication benefits, cost-related self-efficacy, and demographic factors) CRMNA correlates were assessed. Correlates were examined using mixed logistic regression analysis. RESULTS Across all study countries, CRMNA had an average prevalence of 2.6% (range, 0% [Switzerland/Brazil] to 9.8% [Australia]) and was positively related to being single (odds ratio, 2.29; 95% confidence interval, 1.17-4.47), perceived financial burden (odds ratio, 2.15; 95% confidence interval, 1.55-2.99), and cost as a barrier (odds ratio, 2.60; 95% confidence interval, 1.66-4.07). Four protective factors were identified: white ethnicity (odds ratio, 0.37; 95% confidence interval, 0.19-0.74), intention to adhere (odds ratio, 0.44; 95% confidence interval, 0.31-0.63), self-efficacy (odds ratio, 0.54; 95% confidence interval, 0.43-0.67), and belief about medication benefit (odds ratio, 0.70; 95% confidence interval, 0.57-0.87). Regarding variability, 81.3% was explained at the patient level; 13.8%, at the center level; and 4.8%, at the country level. CONCLUSION In heart transplant recipients, the CRMNA prevalence varies across countries but is lower than in other chronically ill populations. Identified patient-level correlates are novel (ie, intention to adhere, cost-related barriers, and cost-related self-efficacy) and indicate patient-perceived medication cost burden.

Am J Kidney Dis 2021; 80:46-54. [PMID: 34673160 DOI: 10.1053/j.ajkd.2021.09.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Accepted: 09/16/2021] [Indexed: 11/11/2022]
Abstract
RATIONALE AND OBJECTIVE Concerns about non-adherent behaviors often prevent dialysis patients from entering waitlists for transplantation, despite an inconsistent association with posttransplant outcomes. We examined the association between plausible metrics of non-adherence related to dialysis treatment and posttransplant outcomes. STUDY DESIGN Retrospective cohort. We linked national dialysis treatment data with transplant registry data. SETTING AND PARTICIPANTS Adult patients on maintenance hemodialysis from 1/1/2004-12/31/2014 who received a kidney transplant at US centers. EXPOSURES We examined five nonadherence metrics: serum potassium (≥5.2 mEq/L), serum phosphorus (>5.5 mg/dL), intradialytic weight gain (IDWG, ≥5 L), shortened treatments (≥30 minutes) and missed treatments (≥1); missed treatment data was only available for 2004-2009. These metrics were characterized as the proportion of time under observation. Dialysis observation time was divided into 3-month intervals (quarters) and the number of "non-adherent" measurements in each domain was calculated for each quarter. OUTCOMES Allograft loss; mortality; and acute rejection in the first posttransplant year. ANALYTICAL APPROACH Using Cox proportional hazards and logistic regression, we estimated the hazard ratios (HRs) for graft loss and mortality, and odds ratios (OR) for rejection. RESULTS 9543 patients met inclusion criteria. In our primary model, hyperphosphatemia (aHR 1.27, 05% CI 1.08-1.49), IDWG (aHR 1.39, 95% CI 1.23-1.59) and shortened treatments (aHR 1.54, 95% CI 1.12-2.13) were associated with greater rates of allograft loss but hyperkalemia was not. IDWG (aHR 1.49, 95% CI 1.29-1.73) and shortened treatments (aHR 1.34, 95% CI 1.13-1.58) were associated with mortality while hyperkalemia and hyperphosphatemia were not. Only shortened treatments was associated with an increased risk of acute rejection (aOR 3.88, 95% CI 1.98-7.58). In models limited to the years 2004 to 2009 that included missed treatments, missed treatments were only associated with mortality. LIMITATIONS Unmeasured confounding (e.g., dietary data); adherence metrics used may have multiple, complex causes. CONCLUSIONS Plausible measures of dialysis nonadherence have long-term associations with allograft and patient survival. Behavioral metrics were more closely associated with outcomes than laboratory markers. The implications of non-adherent behaviors for dialysis patients must be carefully considered before excluding patients from transplantation.

Missing In-Center Hemodialysis Sessions among Patients with End Stage Renal Disease in Banda Aceh, Indonesia. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18179215.

Abstract
Indonesian universal health coverage was implemented in 2013 and hemodialysis services became universally accessible, yet few studies have examined patient adherence to hemodialysis schedules. We examined the rates of missed in-center hemodialysis sessions in Banda Aceh and the factors associated with non-attendance. This cross-sectional questionnaire survey included 193 patients receiving in-center hemodialysis. Approximately 28% of the patients missed ≥ 1 hemodialysis session in the month prior to the questionnaire’s administration. About 65% reported attending religious activities as the reason for missing hemodialysis. The level of health literacy was generally low with a mean score of 14.38 out of 26 (55.3%). Multivariate logistic regression analyses showed that patients with educational levels higher than elementary school were less likely to miss hemodialysis sessions. Participants who performed more self-care behaviors had lower odds of missing hemodialysis sessions. Every unit increase in the health literacy score was associated with increased odds of missing hemodialysis sessions. Emphasizing the importance of attending hemodialysis sessions and modifying hemodialysis schedules based on patients’ needs is essential. Patients who miss hemodialysis sessions should be reminded of all self-care behaviors. Health literacy among hemodialysis patients should be improved, with emphasis on patient safety, advanced knowledge, and critical health literacy.

Abstract
In recent years, large cohort studies of patients with chronic kidney disease (CKD) have been established all over the world. These studies have attempted to analyze the pathogenesis of CKD using a large body of published evidence. The design of cohort studies is characterized by the measurement of the exposure prior to the occurrence of the outcome, which has the advantage of clarifying the temporal relationship between predictors and outcomes and estimating the strength of the causal relationship between predictors and multiple outcomes. Recent advances in biostatistical analysis methods, such as propensity scores and risk prediction models, are facilitating causal inference using higher quality evidence with greater precision in observational studies. In this review, we will discuss clinical epidemiological research of kidney disease based on the analysis of observational cohort data sets, with a focus on our previous studies.

Abstract
BACKGROUND Wasting is a common complication of kidney failure that leads to weight loss and poor outcomes. Recent experimental data identified parathyroid hormone (PTH) as a driver of adipose tissue browning and wasting, but little is known about the relations among secondary hyperparathyroidism, weight loss, and risk of mortality in dialysis patients. METHODS We included 42,319 chronic in-centre haemodialysis patients from the Dialysis Outcomes and Practice Patterns Study phases 2-6 (2002-2018). Linear mixed models were used to estimate the association between baseline PTH and percent weight change over 12 months, adjusting for country, demographics, comorbidities, and labs. Accelerated failure time models were used to assess 12 month weight loss as a mediator between baseline high PTH and mortality after 12 months. RESULTS Baseline PTH was inversely associated with 12 month weight change: 12 month weight loss >5% was observed in 21%, 18%, 18%, 17%, 15%, and 14% of patients for PTH ≥600 pg/mL, 450-600, 300-450, 150-300, 50-150, and <50 pg/mL, respectively. In adjusted analyses, 12 month weight change compared with PTH 150-299 pg/mL was -0.60%, -0.12%, -0.10%, +0.15%, and +0.35% for PTH ≥600, 450-600, 300-450, 50-150, and <50 pg/mL, respectively. This relationship was robust regardless of recent hospitalization and was more pronounced in persons with preserved appetite. During follow-up after the 12 month weight measure [median, 1.0 (interquartile range, 0.6-1.7) years; 6125 deaths], patients with baseline PTH ≥600 pg/mL had 11% [95% confidence interval (CI), 9-13%] shorter lifespan, and 18% (95% CI, 14-23%) of this effect was mediated through weight loss ≥2.5%. CONCLUSIONS Secondary hyperparathyroidism may be a novel mechanism of wasting, corroborating experimental data, and, among chronic dialysis patients, this pathway may be a mediator between elevated PTH levels and mortality. Future research should determine whether PTH-lowering therapy can limit weight loss and improve longer term dialysis outcomes.

Abstract
Background Non-adherence (NA) to hemodialysis regimens is one of the contributors to the high morbidity and mortality observed in patients with end-stage kidney disease (ESKD). We aimed to determine the prevalence and predictors of NA to hemodialysis (HD) regimens among patients on maintenance HD in Cameroon. Methods A cross-sectional study in two HD centers in Cameroon was conducted from January to February 2016. Consenting patients on HD for ≥3 months were included. NA to fluid restriction was defined as a mean interdialytic weight gain (IDWG) in the past month >5.7% of the dry weight, NA to dietary restriction as a pre dialysis serum phosphorus >5.5 mg/dl in a patient on phosphate binders and who is well-nourished, and NA to HD sessions as skipping at least one session in the past month. The study was approved by the institutional ethics board. Results A total of 170 (112 males) participants with a median age of 49 years (range 14–79) were included. The median dialysis vintage was 35 months (range 3–180 months). The prevalence of NA was 15.3% to fluid restriction, 26.9% to dietary restriction, and 21.2% to dialysis sessions. Age ≤49 years (p = .006, OR: 5.07, 95% CI: 1.59–16.20) and unmarried status (p = .041, OR: 2.63, 95% CI: 1.04–6.66) were independently associated with NA to fluid restrictions. No factor was associated with NA to dietary restrictions and HD sessions. Conclusions NA to HD regimens is common amongst patients in Cameroon. Younger age and being unmarried were the predictors of NA to fluid restriction.

Abstract
High inter-dialytic weight gains (IDWG) and Hyperkalemia have been associated with adverse outcomes like poor quality of life and high mortality. Thirst remains an unsolved problem in hemodialysis (HD) patients. The aim of this study was to evaluate the effect of polyethylene glycol (PEG) based intestinal dialysis on IDWG, thirst and biochemical parameters. A prospective interventional evidenced based paired comparative single center study was conducted. Thirty-five anuric patients on weekly thrice HD were studied for four consecutive dialysis weeks. Before the mid-week dialysis day of week 3, Patients received 2 L PEG solution. The primary end points were change in mean relative IDWG and change in mean subjective thirst feeling as measured on visual analog scale (VAS) with secondary endpoints being change in small molecule clearance. There was significant reduction in IDWG after the therapy from 3 ± 0.81 L to 2.35 ± 0.72 (P = 0.002). The therapy also reduced the % IDWG BW from 5.1 ± 1.7% to 4.15 ± 1.6% (P = 0.017). No change in thirst was seen, that is, 6.16 ± 0.66, 6.14 ± 0.64, and 6.16 ± 0.65 (P = 0.986). A multivariate linear regression did not reveal any effect of age, gender, and co-morbidities on the reduction of IDWG and thirst. The therapy achieved a significant urea, creatinine, and potassium reduction of 8.23%, 8.13%, and 8.33% respectively with an increase in sodium levels by 0.86%. This modality reduced the IDWG, was found to be a potent treatment modality for hyperkalemia but did not affect thirst sensation even after consumption of 2 L solution.

McCullough PA. Phosphate Control: The Next Frontier in Dialysis Cardiovascular Mortality. Cardiorenal Med 2021; 11:123-132.

Abstract
BACKGROUND Cardiovascular disease (CVD) is a major cause of death in patients with chronic kidney disease (CKD) on dialysis. Mortality rates are still unacceptably high even though they have fallen in the past 2 decades. Hyperphosphatemia (elevated serum phosphate levels) is seen in almost all patients with advanced CKD and is by far the largest remaining modifiable contributor to CKD mortality. SUMMARY Phosphate retention drives multiple physiological mechanisms linked to increased risk of CVD. Fibroblast growth factor 23 and parathyroid hormone (PTH) levels, both of which have been suggested to have direct pathogenic CV effects, increase in response to phosphate retention. Phosphate, calcium, and PTH levels are linked in a progressively worsening cycle. Maladaptive upregulation of phosphate absorption is also likely to occur further exacerbating hyperphosphatemia. Even higher phosphate levels within the normal range may be a risk factor for vascular calcification and, thus, CV morbidity and mortality. A greater degree of phosphate control is important to reduce the risk of CV morbidity and mortality. Improved phosphate control and regular monitoring of phosphate levels are guideline-recommended, established clinical practices. There are several challenges with the current phosphate management approaches in patients with CKD on dialysis. Dietary restriction of phosphate and thrice-weekly dialysis alone are insufficient/unreliable to reduce phosphate to <5.5 mg/dL. Even with the addition of phosphate binders, the only pharmacological treatment currently indicated for hyperphosphatemia, the majority of patients are unable to achieve and maintain phosphate levels <5.5 mg/dL (or more normal levels) [PhosLo® gelcaps (calcium acetate): 667 mg (prescribing information), 2011, VELPHORO®: (Sucroferric oxyhydroxide) (prescribing information), 2013, FOSRENAL®: (Lanthanum carbonate) (prescribing information), 2016, AURYXIA®: (Ferric citrate) tablets (prescribing information), 2017, RENVELA®: (Sevelamer carbonate) (prescribing information), 2020, RealWorld dynamix. Dialysis US: Spherix Global Insights, 2019]. Phosphate binders do not target the primary pathway of phosphate absorption (paracellular), have limited binding capacity, and bind nonspecifically [PhosLo® gelcaps (calcium acetate): 667 mg (prescribing information). 2013, VELPHORO®: (Sucroferric oxyhydroxide) (prescribing information), 2013, FOSRENAL®: (Lanthanum carbonate) (prescribing information), 2016, AURYXIA®: (Ferric citrate) tablets (prescribing information), 2017, RENVELA®: (Sevelamer carbonate) (prescribing information) 2020]. Key Messages: Despite current phosphate management strategies, most patients on dialysis are unable to consistently achieve target phosphate levels, indicating a need for therapeutic innovations [RealWorld dynamix. Dialysis US: Spherix Global Insights, 2019]. Given a growing evidence base that the dominant mechanism of phosphate absorption is the intestinal paracellular pathway, new therapies are investigating ways to reduce phosphate levels by blocking absorption through the paracellular pathway.

Abstract
PURPOSE To determine seasonal variations in serum potassium levels among hemodialysis patients. MATERIALS AND METHODS This was a multicenter cohort study of patients whounderwent hemodialysis and were registered in DialysisNet at our four associated general hospitals between January and December 2016. Month-to-month potassium variability was quantified as SD/√{n/(n-1)}, and a non-hierarchical method was used to cluster groups according to potassium trajectories. Seasonal variations in potassium levels were analyzed using a cosinor analysis. RESULTS The analysis was performed on 279 patients with a mean potassium level of 5.08±0.58 mmol/L. After clustering, 52.3% (n=146) of patients were included in the moderate group (K+, 4.6±0.4 mmol/L) and 47.7% (n=133) in the high group (K+, 5.6±0.4 mmol/L). The mean potassium level peaked in January in the moderate group (4.83±0.74 mmol/L) and in August in the high group (5.51±0.70 mmol/L). In the high potassium group, potassium levels were significantly higher in summer than in autumn (p<0.001) and spring (p=0.007). Month-to-month potassium variability was greater in the high group than in the moderate group (0.59±0.19 mmol/L vs. 0.52±0.21 mmol/L, respectively, p=0.012). Compared to patients in the first quartile of potassium variability (≤0.395 mmol/L), those with higher variability (2nd-4th quartiles) were 2.8-4.2 fold more likely to be in the high potassium group. CONCLUSION Different seasonal patterns of serum potassium were identified in the moderate and high potassium groups, with potassium levels being significantly higher in the summer season in the high potassium group and in winter for the moderate potassium group.

Fast track dialysis: Improving emergency department and hospital throughput for patients requiring hemodialysis. Am J Emerg Med 2021; 45:92-99. [PMID: 33677266 DOI: 10.1016/j.ajem.2021.02.035] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 02/14/2021] [Accepted: 02/16/2021] [Indexed: 12/01/2022] Open
Abstract
OBJECTIVE To describe the impact of a novel communication and triage pathway called fast track dialysis (FTD) on the length of stay (LOS), resource utilization, and charges for unscheduled hemodialysis for end stage renal disease (ESRD) patients presenting to the emergency department (ED). METHODS Prospective and retrospective cohorts of ESRD patients meeting requirements of routine or urgent hemodialysis at a tertiary academic hospital from September 25th, 2016 to September 25th, 2018 in 1 year cohorts. Two sample t-tests were used to compare most outcomes of the cohorts with a Mann-Whitney U test used for skewed data. Nephrology group outcomes were analyzed by two-way ANOVA and Kruskal-Wallis and chi-square tests. RESULTS There were 98 encounters in the historical cohort and 143 encounters in the fast track dialysis cohort. FTD had significantly lowered median ED LOS (4.05 h, vs 5.3 h, p < 0.001), median hospital LOS (12.8 h vs 27 h, p < 0.001), time to hemodialysis (4.78 h vs 7.29 h, p < 0.001), and median hospital charges ($26,040 vs $30,747, p < 0.016). The FTD cohort had increased 30 day ED return for each encounter compared to the historical cohort (1.85 visits vs 0.73 visits, p < 0.001), however no significant increase in 1 year ED visits (6.52 visits vs 5.80, p = 0.4589) or 1 year readmissions (5.89 readmissions vs 4.81 readmissions, p = 0.3584). Most nephrology groups had significantly lower time to hemodialysis order placement and time to start hemodialysis. CONCLUSION A multidisciplinary approach with key stakeholders using a standard pathway can lead to improved efficiency in throughput, reduced charges, and hospital resource utilization for patients needing urgent or routine hemodialysis. A study with a dedicated geographic observation unit for protocolized short stay patients including conditions ranging from low risk chest pain to transient ischemic events that incorporates FTD patients under this protocol should be considered.
