Abstract
INTRODUCTION The aim of this study was to determine the level of frailty in older hemodialysis patients and to examine the relationship between their functional capacity, depression, and laboratory variables. METHOD This was a cross-sectional study, and the data were collected 243 dialysis patients aged 65 and over between May 2021 and May 2022. RESULTS The frailty rate was 49%. A statistically significant positive correlation was found between the frailty and age, hemodialysis vintage, and the number of hospitalizations. The frailty was negatively correlated with body mass index, Kt/V, Albumin, and parathyroid hormone. There was a statistically significant positive correlation between frailty and depression and a negative correlation between functional capacity. CONCLUSION A relationship was found between frailty and depression, functional capacity, and laboratory variables. In addition, the variables affecting the level of frailty in geriatric dialysis patients included dialysis vintage, dialysis adequacy, number of hospitalizations, albumin level, and patient weight.

[PMID: 37031361 DOI: 10.1111/jorc.12466] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 01/26/2023] [Accepted: 03/16/2023] [Indexed: 04/10/2023]
Abstract
BACKGROUND Dialysis might not benefit all older patients with kidney failure, particularly those with multimorbid conditions and frailty. Patients' and healthcare professionals' awareness of the presence of geriatric impairments could improve outcomes by tailoring treatment plans and decisions for individual patients. OBJECTIVE We aimed to explore the perspectives of patients and healthcare professionals on nephrology-tailored geriatric assessment to fuel decision-making for treatment choices in older patients with kidney failure. DESIGN In an exploratory qualitative study using focus groups, participants discussed perspectives on the use and value of nephrology-tailored geriatric assessment for the decision-making process to start or forego dialysis. PARTICIPANTS AND MEASUREMENTS Patients (n = 18) with kidney failure, caregivers (n = 4), and professionals (n = 25) were purposively sampled from 10 hospitals. Interviews were audio-recorded, transcribed verbatim and inductively analysed using thematic analysis. RESULTS Three main themes emerged that supported or impeded decision-making in kidney failure: (1) patient psycho-social situation; (2) patient-related factors on modality choice; (3) organisation of health care. Patients reported feeling vulnerable due to multiple chronic conditions, old age, experienced losses in life and their willingness to trade longevity for quality of life. Professionals recognised the added value of nephrology-tailored geriatric assessment in three major themes: (i) facilitating continual holistic assessment, (ii) filling the knowledge gap, and (iii) uncovering important patient characteristics. CONCLUSIONS nephrology-tailored geriatric assessment was perceived as a valuable tool to identify geriatric impairments in older patients with kidney failure. Integration of its outcomes can facilitate a more holistic approach to inform choices and decisions about kidney replacement therapy.

Abstract
Rationale & Objective Older people with progressive chronic kidney disease (CKD) have complex health care needs. Geriatric evaluation preceding decision making for kidney replacement is recommended in guidelines, but implementation is lacking in routine care. We aimed to evaluate implementation of geriatric assessment in CKD care. Study Design Mixed methods implementation study. Setting & Participants Dutch nephrology centers were approached for implementation of geriatric assessment in patients aged ≥70 years and with an estimated glomerular filtration rate of ≤20 mL/min/1.73 m2. Quality Improvement Activities/Exposure We implemented a consensus-based nephrology-tailored geriatric assessment: a patient questionnaire and professionally administered test set comprising 16 instruments covering functional, cognitive, psychosocial, and somatic domains and patient-reported outcome measures. Outcomes We aimed for implementation in 10 centers and 200 patients. Implementation was evaluated by (i) perceived enablers and barriers of implementation, including integration in work routines (Normalization Measure Development Tool) and (ii) relevance of the instruments to routine care for the target population. Analytical Approach Variations in implementation practices were described based on field notes. The postimplementation survey among health care professionals was analyzed descriptively, using an explanatory qualitative approach for open-ended questions. Results Geriatric assessment was implemented in 10 centers among 191 patients. Survey respondents (n = 71, 88% response rate) identified determinants that facilitated implementation, ie, multidisciplinary collaboration (with geriatricians) -meetings and reports and execution of assessments by nurses. Barriers to implementation were patient illiteracy or language barrier, time constraints, and patient burden. Professionals considered geriatric assessment sufficiently integrated into work routines (mean, 6.7/10 ± 2.0 [SD]) but also subject to improvement. Likewise, the relevance of geriatric assessment for routine care was scored as 7.8/10 ± 1.2. The Clinical Frailty Score and Montreal Cognitive Assessment were perceived as the most relevant instruments. Limitations Selection bias of interventions' early adopters may limit generalizability. Conclusions Geriatric assessment could successfully be integrated in CKD care and was perceived relevant to health care professionals.

Development of a prognostic risk score to predict early mortality in incident elderly Japanese hemodialysis patients. PLoS One 2024; 19:e0302101.

Abstract
BACKGROUND Information of short-term prognosis after hemodialysis (HD) introduction is important for elderly patients with chronic kidney disease (CKD) and their families choosing a modality of renal replacement therapy. Therefore, we developed a risk score to predict early mortality in incident elderly Japanese hemodialysis patients. MATERIALS AND METHODS We analyzed data of incident elderly HD patients from a nationwide cohort study of the Japanese Society for Dialysis Therapy Renal Data Registry (JRDR) to develop a prognostic risk score. Candidate risk factors for early death within 1 year was evaluated using multivariate logistic regression analysis. The risk score was developed by summing up points derived from parameter estimate values of independent risk factors. The association between risk score and early death was tested using Cox proportional hazards models. This risk score was validated twice by using an internal validation cohort derived from the JRDR and an external validation cohort collected for this study. RESULTS Using the development cohort (n = 2,000), nine risk factors were retained in the risk score: older age (>85), yes = 2, no = 0; sex, male = 2, female = 0; lower body mass index (<20), yes = 2, no = 0; cancer, yes = 1, no = 0; dementia, yes = 3, no = 0; lower creatinine (<6.5 mg/dL), yes = 1, no = 0; lower albumin (<3.0 g/dL), yes = 3, no = 0; normal or high calcium (≥8.5 mg/dL), yes = 1, no = 0; and higher C reactive protein (>2.0 mg/dL), yes = 2, no = 0. In the internal and external validation cohorts (n = 739, 140, respectively), the medium- and high-risk groups (total score, 6 to 10 and 11 or more, respectively) showed significantly higher risk of early death than the low-risk group (total score, 0 to 5) (p<0.001). CONCLUSION We developed a prognostic risk score predicting early death within 1 year in incident elderly Japanese HD patients, which may help detect elderly patients with a high-risk of early death after HD introduction.

Abstract
Frailty is a multidimensional clinical syndrome characterized by low physical activity, reduced strength, accumulation of multiorgan deficits, decreased physiological reserve, and vulnerability to stressors. Frailty has key social, psychological, and cognitive implications. Frailty is accelerated by uremia, leading to a high prevalence of frailty in patients with advanced chronic kidney disease (CKD) and end-stage kidney disease (ESKD) as well as contributing to adverse outcomes in this patient population. Frailty assessment is not routine in patients with CKD; however, a number of validated clinical assessment tools can assist in prognostication. Frailty assessment in nephrology populations supports shared decision-making and advanced communication and should inform key medical transitions. Frailty screening and interventions in CKD or ESKD are a developing research priority with a rapidly expanding literature base.

Abstract
BACKGROUND This study aimed to evaluate the correlation between serum methylmalonic acid (MMA) levels and cognition function in patients with chronic kidney disease (CKD). METHODS In this cross-sectional study, we included 537 CKD individuals aged ≥ 60-year-old with albuminuria from the National Health and Nutrition Examination Survey (NHANES) 2011-2014. Four cognitive tests including the Digit Symbol Substitution Test (DSST), the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) Delayed Recall and Word Learning tests, and the Animal Fluency test (AF) were performed. Associations between MMA and cognition scores were assessed with linear regression models. RESULTS MMA level was negatively associated with residual renal function and nutrition status. After multivariate adjustment, elevated serum MMA levels were independently correlated with decline of cognition in CKD patients with albuminuria. CONCLUSION Our study showed that higher serum MMA levels were independently associated with the presence of cognition dysfunction in CKD patients. The exact pathogenesis of MMA and cognition needs further research.

Abstract
INTRODUCTION Despite all available evidence regarding increased morbidity and mortality among dialysis patients due to falls and their complications, and an increase in risk factors for falls, relatively little attention has been focused on evidence-based interventions that can reduce falls. We evaluated the effectiveness of fall prevention interventions among dialysis patients. METHODS We searched Ovid-Medline, Ovid-Embase, PubMed, Cumulated Index to Nursing and Allied Health Literature and the Cochrane Central Register of Controlled Trials (Central) from inception to 19 July 2023 for studies that evaluated the effectiveness of fall prevention interventions among dialysis patients. The search, screening and extraction of data followed standardised processes and the methodological quality of studies was independently assessed by two reviewers. Data was analysed using a narrative synthesis approach. RESULTS Of the 18 studies that had full text review, five were eligible. Three studies were performed in the USA and one each in UK and Japan. Four studies were conducted in outpatient hemodialysis centres and one in a hospital-based nephrology unit. Reported sample sizes ranged from 51 to 96 participants per study with a follow-up period of 3 to 35 months. There was moderate-quality evidence that exercises reduce the rate of falls compared to usual care and low to moderate quality of evidence that multifactorial falls prevention interventions reduce the rate of falls. However, treatment effects could not be quantitatively estimated for all interventions due to substantial heterogeneity of included studies. CONCLUSIONS This systematic review reflects that there is insufficient evidence regarding falls prevention strategies specific to dialysis patients. Available data based on low to moderate quality studies, suggest that among dialysis patients, exercises may reduce falls and the effectiveness of multifactorial interventions such as staff and patient education still need to be explored using high-quality prospective studies.

Abstract
BACKGROUND Cognitive frailty describes the co-occurrence of cognitive impairment and physical frailty and is classified into reversible and irreversible phenotypes. Data on the impact of COVID-19 pandemic imposed lockdowns, locally known as the Movement Control Order (MCO), on the psychological status of cognitively frail older adults remain scarce. Therefore, this study aimed to determine the relationship between depression, anxiety, stress and cognitive frailty among older adults during the MCO. METHOD Participants aged above 60 years from three ageing cohorts in Malaysia were interviewed virtually. The Fatigue, Resistance, Ambulation, Illness and Loss of Weight scale, blind Montreal Cognitive Assessment, 15-item Geriatric Depression Scale, anxiety subscale of Depression, Anxiety and Stress Scale and four-item Perceived Stress Scale measured frailty, mild cognitive impairment (MCI), depression, anxiety and stress, respectively. RESULTS Cognitive frailty data were available for 870 participants, age (mean ± SD) = 73.44 ± 6.32 years and 55.6% were women. Fifty-seven (6.6%) were robust, 24 (2.8%) had MCI, 451 (51.8%) were pre-frail, 164 (18.9%) were pre-frail+MCI, 119 (13.7%) were frail and 55 (6.3%) were frail+MCI. There were significant differences in depression and anxiety scores between the controlled MCO and recovery MCO. Using multinomial logistic regression, pre-frail (mean difference (95% confidence interval, CI) = 1.16 (0.932, 1.337), frail (1.49 (1.235, 1.803) and frail+MCI (1.49 (1.225, 1.822)) groups had significantly higher depression scores, frail (1.19 (1.030, 1.373)) and frail+MCI (1.24 (1.065, 1.439)) had significantly higher anxiety scores and pre-frail (1.50 (1.285, 1.761)), frail (1.74 (1.469, 2.062)) and frail+MCI (1.81 (1.508, 2.165)) had significantly higher stress scores upon adjustments for the potential confounders. The MCO was a potential confounder in the relationship between depression and prefrail+MCI (1.08 (0.898, 1.340)). CONCLUSION Frail individuals with or without MCI had significantly higher depression, anxiety and stress than those who were robust. Increased depression and stress were also observed in the pre-frail group. Interventions to address psychological issues in older adults during the COVID-19 pandemic could target prefrail and frail individuals and need further evaluation.

Abstract
The demographic evolution of patients with advanced chronic kidney disease (CKD) has led to the advent of an alternative treatment option to kidney replacement therapy in the past couple of decades. The KDIGO controversies on Kidney Supportive Care called this approach "comprehensive conservative care" (CCC) and defined it as planned holistic patient-centered care for patients with CKD stage 5 that does not include dialysis. Although the benefit of this treatment option is now well-recognized, especially for the elderly, and comorbid and frail patients, its development remains limited in practice. While shared decision-making and advance care planning represent the cornerstones of the CCC approach, one of the main barriers in its development is the perfectible communication between nephrologists and patients, but also between all healthcare professionals involved in the care of advanced CKD patients. As a result, a significant gap has opened up between what doctors say and what patients hear. Indeed, although CCC is reported by nephrologists to be widely available in their facilities, few of their patients say that they have actually heard of it. The objectives of this review are to explore discrepancies between what doctors say and what patients hear, to identify the factors underlying this gap, and to formulate practical proposals for narrowing this gap in practice.

A prospective, observational study of frailty, quality of life and dialysis in older people with advanced chronic kidney disease. BMC Geriatr 2023; 23:664. [PMID: 37845618 PMCID: PMC10580596 DOI: 10.1186/s12877-023-04365-4] [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: 04/18/2023] [Accepted: 09/29/2023] [Indexed: 10/18/2023] Open
Abstract
BACKGROUND Frailty is prevalent in older people with chronic kidney disease (CKD) and robust evidence supporting the benefit of dialysis in this setting is lacking. We aimed to measure frailty and quality of life (QOL) longitudinally in older people with advanced CKD and assess the impact of dialysis initiation on frailty, QOL and mortality. METHODS Outpatients aged ≥65 with an eGFR ≤ 20ml/minute/1.73m2 were enrolled in a prospective observational study and followed up four years later. Frailty status was measured using a Frailty Index (FI), and QOL was evaluated using the EuroQol 5D-5L instrument. Mortality and dialysis status were determined through inspection of electronic records. RESULTS Ninety-eight participants were enrolled. Between enrolment and follow-up, 36% of participants commenced dialysis and 59% died. Frailty prevalence increased from 47% at baseline to 86% at follow-up (change in median FI = 0.22, p < 0.001). Initiating dialysis was not significantly associated with change in FI. QOL declined from baseline to follow-up (mean EQ-5D-5L visual analogue score of 70 vs 63, p = 0.034), though commencing dialysis was associated with less decline in QOL. Each 0.1 increment in baseline FI was associated with 59% increased mortality hazard (HR = 1.59, 95%CI = 1.20 to 2.12, p = 0.001), and commencing dialysis was associated with 59% reduction in mortality hazard (HR = 0.41, 95%CI = 0.20 to 0.87, p = 0.020) irrespective of baseline FI. CONCLUSIONS Frailty increased substantially over four years, and higher baseline frailty was associated with greater mortality. Commencing dialysis did not affect the trajectory of FI but positively influenced the trajectory of QOL from baseline to follow-up. Within the limitations of small sample size, our data suggests that frail participants received similar survival benefit from dialysis as non-frail participants.

J Adv Nurs 2023; 79:3691-3706. [PMID: 37357980 DOI: 10.1111/jan.15746] [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: 05/02/2022] [Revised: 05/25/2023] [Accepted: 06/10/2023] [Indexed: 06/27/2023]
Abstract
AIMS To systematically identify the risk factors for cognitive impairment in maintenance haemodialysis patients and to assess its prevalence in included studies. DESIGN Systematic review and meta-analysis about observational studies. DATA SOURCES Systematic search of seven databases, including PubMed, Web of Science, Scope, Wanfang Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database and Weipu Chinese Science and Technology Journal Database, from inception until October 2021. REVIEW METHODS Observational studies reporting the risk factors for cognitive impairment in maintenance haemodialysis patients in English and Chinese language were included. Meta-analysis was performed to identify risk factors and prevalence of cognitive impairment in maintenance haemodialysis patients with STATA 15.0 software. RESULTS Overall, 37 eligible studies encompassing 129,849 cases were included. The risk factors with statistical significance after meta-analysis were older age, female sex, fewer years of education, hypertension, diabetes, cerebrovascular accident, multiple comorbid conditions, systolic blood pressure variability, arterial stiffness and low haemoglobin and albumin level. The overall prevalence of cognitive impairment in maintenance haemodialysis patients was 49.1%. CONCLUSION The current analysis indicated a high prevalence of cognitive impairment in maintenance haemodialysis patients. Eleven risk factors for cognitive impairment in maintenance haemodialysis patients were identified, among which more attention should be paid to modifiable factors such as cardiovascular disease risk factors and specific kidney and dialysis-related factors. IMPACT This paper provides an updated estimate of the pooled prevalence of cognitive impairment in maintenance haemodialysis patients. Identification of risk factors associated with cognitive impairment may assist in developing targeted prevention strategies for maintenance haemodialysis patients at high risk. NO PATIENT OR PUBLIC CONTRIBUTION This study was a systematic review completed by the authors in accordance with relevant guidelines and processes and did not include the participation of patients, service users, caregivers or the general public.

Abstract
OBJECTIVES Cognitive impairment is common in haemodialysis patients and is associated with increased hospitalization and mortality. However, subjective cognitive complaints (SCCs), the self-experienced difficulties in everyday cognitive activities, remain poorly understood. This study examined the prevalence and course of SCCs in haemodialysis patients and its longitudinal associations with sociodemographic, clinical and patient-reported variables. DESIGN Observational prospective study with baseline and 12-month follow-up assessment. METHODS Based on a validated cut-off point on the Kidney Disease Quality of Life Cognitive Function subscale, haemodialysis patients (N = 159; 40.3% female, mean age 53.62) were classified into cognitive complaint trajectories: (1) resilient (60.4%; no/low SCCs throughout); (2) persistent (8.8%; stable high SCCs); (3) deterioration (17.6%; from no/low to high SCCs); and (4) recovery (13.2%; from high to no/low SCCs). Sociodemographic/clinical characteristics, self-efficacy, self-management skills, adherence, mood and biochemical assays were measured at both assessments and compared among trajectories using mixed ANOVAs. RESULTS Interaction effects indicated significant improvements in the recovery group in clinical outcomes (i.e., decreased phosphorus and calcium-phosphorus product), self-efficacy and mood over time. Group effects indicated significantly poorer self-efficacy, self-management skills and adherence in the persistent group than other trajectories across both assessments. None of the sociodemographic/clinical characteristics was associated with SCC trajectories. CONCLUSIONS The extent of SCCs vary over time across haemodialysis patients. Routine screening of SCCs in dialysis settings may help identifying patients at risk of poor self-management and worse prognosis. Strategies that compensate for cognitive lapses may mitigate the perceived cognitive burden of this population.

Abstract
Background With an aging population and growing number of patients with chronic kidney disease (CKD), integrating the latest risk factors when deciding on a treatment plan can result in better patient care. Frailty remains a prevalent syndrome in CKD resulting in adverse health outcomes. However, measures of frailty and functional status remain excluded from clinical decision making. Objective To examine the degree to which different measures of frailty and functional status are associated with mortality, hospitalization, and other clinical outcomes in patients with advanced CKD. Design Systematic review. Setting Observation studies including cohort study, case-control study, or cross-sectional study examining frailty and functional status on clinical outcomes. There were no restrictions on type of setting or country of origin. Patients Adults with advanced CKD, including both types of dialysis patients. Measurements Data including demographic information (e.g., sample size, follow-up time, age, country), assessments of frailty or functional status and their domains, and outcomes including mortality, hospitalization, cardiovascular events, kidney function, and composite outcomes were extracted. Methods A search was conducted using databases Medline, Embase, and Cochrane Central Register for Controlled Trials. Studies were included from inception to March 17, 2021. The eligibility of studies was screened by 2 independent reviewers. Data were presented by instrument and clinical outcome. Point estimates and 95% confidence intervals from the fully adjusted statistical model were reported or calculated from the raw data. Results A total of 117 unique instruments were found among 140 studies. The median sample size of studies was 319 (interquartile range, 161-893). Most studies focused on incident and chronic dialysis patient populations, with only 15% of studies examining non-dialysis CKD patients. Frailty and lower functional status were associated with an increased risk for adverse clinical outcomes such as mortality and hospitalization. The 5 individual domains of frailty were also found to be associated with poor health outcomes. Limitations Meta-analysis could not be performed due to significant heterogeneity between studies and methods used to measure frailty and functional status. Many studies had issues with methodological rigor. Selection bias and the validity of data collection could not be ascertained for some studies. Conclusion Frailty and functional status measures should be integrated to help guide clinical care decision making for a comprehensive assessment of risk for adverse outcomes among patients with advanced CKD.

Abstract
INTRODUCTION Many people ageing with HIV are also living with multiple comorbidities and geriatric syndromes including frailty and cognitive deterioration. These complex needs can be challenging to meet within existing HIV care services. This study investigates the acceptability and feasibility of screening for frailty and of using a comprehensive geriatric assessment approach, delivered via the Silver Clinic, to support people living with HIV affected by frailty. METHODS AND ANALYSIS Mixed-methods, parallel-group, randomised, controlled feasibility trial aiming to recruit 84 people living with HIV≥50, identified as frail. Participants will be recruited from the HIV unit at the Royal Sussex County Hospital, University Hospitals Sussex NHS Foundation Trust, Brighton, UK. Participants will be randomised 1:1 to receive usual HIV care or the Silver Clinic intervention, which uses a comprehensive geriatric assessment approach. Psychosocial, physical and service use outcomes will be measured at baseline, 26 weeks and 52 weeks. Qualitative interviews will be conducted with a subset of participants from both arms. Primary outcome measures include recruitment and retention rates and completion of clinical outcome measures. These will be used in conjunction with a priori progression criteria and the qualitative data (acceptability of trial procedures and intervention) to determine the feasibility and design of a definitive trial. ETHICS AND DISSEMINATION This study has been approved by East Midlands-Leicester Central Research Ethics Committee (reference 21/EM/0200). All participants will receive written information about the study and be required to provide informed consent. Results will be disseminated via peer-reviewed journals, conferences and community engagement. TRIAL REGISTRATION NUMBER ISRCTN14646435.

Abstract
Frailty, characterized by a decreased physiological reserve and an increased vulnerability to stressors, is common among kidney transplant (KT) candidates and recipients. In this review, we present and summarize the key arguments for and against the assessment of frailty as part of KT evaluation. The key arguments for including frailty were: (i) sheer prevalence and far-reaching consequences of frailty on KT, and (ii) the ability to conduct a more holistic and objective evaluation of candidates, removing the inaccuracy associated with 'eye-ball' assessments of transplant fitness. The key argument against were: (i) lack of agreement on the definition of frailty and which tools should be used in renal populations, (ii) a lack of clarity on how, by whom and how often frailty assessments should be performed, and (iii) a poor understanding of how acute stressors affect frailty. However, it is the overwhelming opinion that the time has come for frailty assessments to be incorporated into KT listing. Although ongoing areas of uncertainty exist and further evidence development is needed, the well-established impact of frailty on clinical and experiential outcomes, the invaluable information obtained from frailty assessments, and the potential for intervention outweigh these limitations. Proactive and early identification of frailty allows for individualized and improved risk assessment, communication and optimization of candidates.

Abstract
Simple Summary There are an increasing number of older people living with kidney cancer and/or cancer and kidney disease worldwide, sparking a wider discussion on the impact of frailty and the clinical significance of conducting frailty assessments for this patient population. We provide an update on the current evidence related to frailty assessment in onconephrology and identify areas where further research efforts are anticipated to address knowledge gaps within this topic. Abstract Onconephrology has emerged as a novel sub-specialty of nephrology dedicated to the intersection between the kidney and cancer. This intersection is broad and includes a number of important areas of focus, including concurrent chronic kidney disease (CKD) and cancer, acute kidney complications of cancer, and cancer-treatment-induced nephrotoxicity. The importance of onconephrology is even more evident when considering the global growth in the population of older adults, many of whom are living with some degree of frailty. Furthermore, a considerable proportion of older adults have CKD (some of whom eventually progress to kidney failure) and are at high risk of developing solid tumour and hematologic malignancies. Specific to kidney disease, the association between frailty status and kidney disease has been explored in depth, and tools to capture frailty can be used to guide the management and prognostication of older adults living with kidney failure. Whilst there is emerging data regarding the assessment and impact of frailty in onconephrology, there remains a relative paucity of knowledge within this topic. In this article, we evaluate the definition and operationalization of frailty and discuss the significance of frailty within onconephrology. We review evidence on current approaches to assessing frailty in onconephrology and discuss potential developments and future directions regarding the utilization of frailty in this patient population. A greater awareness of the intersections and interactions between frailty and onconephrology and further efforts to integrate frailty assessment in onconephrology to optimize the delivery of realistic and goal-directed management strategies for patients is needed.

Predicting cognitive impairment in chronic kidney disease patients using structural and functional brain network: An application study of artificial intelligence. Prog Neuropsychopharmacol Biol Psychiatry 2023; 122:110677. [PMID: 36395980 DOI: 10.1016/j.pnpbp.2022.110677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 08/20/2022] [Accepted: 11/10/2022] [Indexed: 11/16/2022]
Abstract
OBJECTIVE To develop and validate artificial intelligence models for the prediction of cognitive impairment in chronic kidney disease (CKD) patients using structural and functional brain network. METHODS This study retrospectively recruited 621 CKD patients and 625 healthy controls in Jinling hospital and 57 CKD patients in Hainan hospital. These CKD patients were divided into cognitive function impairment (CFI) group and non-CFI group based on diagnostic criteria. All patients underwent brain MRI scan, neuropsychological test and laboratory exam. A deep learning model (Attention MLP) based on structural and functional sub-network (determined by the comparison between the patients and healthy controls) topological properties was developed to generate the MRI signature for the discrimination of CFI. Finally, a clinical-topological logistic regression model was built by combining MRI signature and clinical features. The area under curve (AUC), sensitivity and specificity were calculated to evaluate the model performance. Delong test was used to examine the difference of AUCs between models. The integrated discrimination improvement (IDI) and net reclassification index (NRI) between models were calculated. RESULTS Attention MLP model performed well in both internal test set and external test set (AUC = 0.744 and 0.763, respectively). After combining with the clinical features, the model performance was further improved both in the internal (AUC: 0.748) and external test sets (AUC: 0.774), while both IDI and NRI were significant (all p < 0.05) in the external test set. According to the comprehensive comparison, the AUC of the Attention MLP model was significantly or marginal significantly higher than that of traditional machine learning models (logistic regression: AUC = 0.634; support vector machine: AUC = 0.613; decision tree: AUC = 0.539; XGBoost: AUC = 0.639) in internal test set. The results showed that the model built on the combining of structural and functional networks data outperformed those on the single network, as well as the connection matrix. CONCLUSION The result indicated that the integration of the clinical information and the MRI signature generated by artificial intelligence model based on structural and functional network topological properties could help to predict the CFI of CKD patients effectively. Our results provided a set of quantifiable imaging biomarkers for CFI which may be beneficial to CKD patients.

Abstract
The aim of this paper is to illustrate all the clinical epidemiology searches made within the French network REIN to improve CKD stage 4-5 care in older adults. We summarize various studies describing clinical practice, care organization, prognosis and health economics evaluation in order to develop personalized care plans and decision-making tools. In France, for 20 years now, various databases have been mobilized including the national REIN registry which includes all patients receiving dialysis or transplantation. REIN data are indirectly linked to the French administrative healthcare database. They are also pooled with data from the PSPA cohort, a multicenter prospective cohort study of patients aged 75 or over with advanced CKD, monitored for 5 years, and the CKD-REIN clinical-based prospective cohort which included 3033 patients with CKD stage 3-4 from 2013 to 2016. During our various research work, we identified heterogeneous trajectories specific to this growing older population, raising ethical, organizational and economic issues. Renal registries will help clinicians, health providers and policy-makers if suitable decision- making tools are developed and validated.

Abstract
We have developed a supportive two-exchange assisted continuous ambulatory peritoneal dialysis (asCAPD) programme for the older frail person who cannot do autonomous PD and do not want or are considered to be too high risk for haemodialysis (HD). Evaluation of the programme was determined by data collected retrospectively from patient records. Primary outcome was comparison of symptoms at start of dialysis and 3 months following dialysis start. Secondary outcomes were survival and peritonitis rate. Over a 4-year period (2016-2020), 49 patients with mean age 79.6 years (range 47-90) enrolled in the programme with eGFR 7.7 ± 2.6 ml/min (mean ± SD) at dialysis start. Forty-one patients had been on asCAPD for >3 months. There was an improvement in all symptoms at 3 months compared to baseline: anorexia (46% to 15%), fatigue (46% to 15%), shortness of breath (27% to 2%) and oedema (51% to 32%). One-year survival was 55%. Peritonitis rate was 0.52 episodes per patient year. The novel supportive two-exchange asCAPD programme shows potential improvement of symptoms after 3 months and may provide an acceptable dialysis modality for the frail co-morbid person with established kidney failure. More detailed study and evaluation are needed.

PURPOSE To investigate the association between sarcopenia with the number of all-cause mortality, hospitalizations, and cardiovascular diseases in patients with end-stage renal disease (ESRD). METHODS 247 patients with ESRD (women, n = 97) (66.6 ± 3.53 years) participated in this study. At baseline, all participants were measured with dual-energy X-ray absorptiometry and handgrip dynamometer and were prospectively followed up for 5 years. The European Working Group on Sarcopenia in Older People guidelines were utilized for Sarcopenia determination. Cox proportional hazard analysis adjusted for established risk factors was used to quantify the risk between Sarcopenia and all-cause mortality. RESULTS Sixty-five participants (26%) were determined to have Sarcopenia at baseline and 38 (15%) have died during the follow-up. At baseline, Participants with Sarcopenia had lower body mass index and fat-free mass index. Moreover, through the 5-year follow-up, sarcopenic patients had higher number of cardiovascular disease (56.9% vs. 12.6%) and hospitalizations (93.8% vs. 49.5%) (all P < 0.0001). Sarcopenia was associated with significantly higher risk of mortality, [Hazard ratio = 3.3, (95% CI: 1.6-6.9), P = 0.001]. CONCLUSION Sarcopenia may be a risk factor for hospitalizations, cardiovascular diseases, and all-cause mortality in patients with ESRD. These results provide support of the relevance in assessing sarcopenia in the clinical practice of chronic kidney disease and how muscle mass and strength may negatively impact the daily life of ESRD patients undergoing hemodialysis. Greater efforts at preventing muscle wasting and malfunctioning are needed through the worldwide healthcare system.

Abstract
BACKGROUND No available and easy to administer cognitive test has been evaluated for the prediction of mortality in prevalent patients on chronic hemodialysis. The aim of the present study was to determine if the Mini-Mental State Examination (MMSE) was predictor of mortality in patients on chronic hemodialysis. METHODS One hundred twenty-seven prevalent patients on chronic hemodialysis were studied. All patients underwent assessment of cognitive function through the MMSE. The MMSE was administered during a midweek hemodialysis session, avoiding the beginning and the end of each treatment to minimize the effects of fluctuations in uremic syndrome or blood pressure in accordance with a previous study. An MMSE score ≤23 was used as indicative of cognitive impairment. Demographic, clinical, and laboratory parameters were recorded for each patient. RESULTS Mean (SD) MMSE was 23.2 ± 4.1. Median MMSE was 24 (min-max: 2-30). MMSE was ≤23 in 72 patients and >23 in 55. With data updated in March 2021, after a mean follow-up of 58.8 ± 41 months (range: 2-156 months), 75 patients died, and 17 were transplanted. None was lost to follow-up or was transferred to another unit. Dead participants, as compared with alive ones, were significantly older, had a higher Charlson Index score, had lower Activities daily living and Instrumental activities daily living, and had a lower MMSE score and lower serum albumin levels. Kaplan-Meier analysis showed that survival was significantly lower in patients with MMSE ≤23 than in those with MMSE >23 (log-rank χ2 : 8.825, p = 0.003). According to Cox regression analysis, mortality was associated with age and inversely associated with MMSE. CONCLUSION We show that the MMSE predicts mortality in prevalent patients on chronic hemodialysis.

Abstract
INTRODUCTION Shared treatment decision-making and planning of care are fundamental in advanced chronic kidney disease (CKD) management. There are limited data on several key outcomes for the elderly population including survival, quality of life, symptom burden, changes in physical functioning and experienced burden of healthcare. Patients, caregivers and clinicians consequently face significant uncertainty when making life-impacting treatment decisions. The Elderly Advanced CKD Programme includes quantitative and qualitative studies to better address challenges in treatment decision-making and planning of care among this increasingly prevalent elderly cohort. METHODS AND ANALYSIS The primary component is OUTcomes of Older patients with Kidney failure (OUTLOOK), a multicentre prospective observational cohort study that will enrol 800 patients ≥75 years with kidney failure (estimated glomerular filtration rate ≤15 mL/min/1.73 m2) across a minimum of six sites in Australia. Patients entered are in the decision-making phase or have recently made a decision on preferred treatment (dialysis, conservative kidney management or undecided). Patients will be prospectively followed until death or a maximum of 4 years, with the primary outcome being survival. Secondary outcomes are receipt of short-term acute dialysis, receipt of long-term maintenance dialysis, changes in biochemistry and end-of-life care characteristics. Data will be used to formulate a risk prediction tool applicable for use in the decision-making phase. The nested substudies Treatment modalities for the InfirM ElderLY with end stage kidney disease (TIMELY) and Caregivers of The InfirM ElderLY with end stage kidney disease (Co-TIMELY) will longitudinally assess quality of life, symptom burden and caregiver burden among 150 patients and 100 caregivers, respectively. CONsumer views of Treatment options for Elderly patieNts with kiDney failure (CONTEND) is an additional qualitative study that will enrol a minimum of 20 patients and 20 caregivers to explore experiences of treatment decision-making and care. ETHICS AND DISSEMINATION Ethics approval was obtained through Sydney Local Health District Human Research Ethics Committee (2019/ETH07718, 2020/ETH02226, 2021/ETH01020, 2019/ETH07783). OUTLOOK is approved to have waiver of individual patient consent. TIMELY, Co-TIMELY and CONTEND participants will provide written informed consent. Final results will be disseminated through peer-reviewed journals and presented at scientific meetings.

Abstract
The growing older population with advanced chronic kidney disease (ACKD stages 4-5) poses a challenge for healthcare worldwide. The high prevalence of frailty and associated adverse health outcomes highlights concerns for management and interventions specific to this population. The aim was to objectively review the evidence relating to older people (≥65 years) living with frailty and ACKD. More specifically how frailty is identified, what interventions have been studied and what outcomes have been reported including outcomes important to patients, families and carers. A scoping review was undertaken following the PRISMA-Scr guidelines. Nine databases were searched and a review team of five people followed a process using defined inclusion and exclusion criteria. Data were then analysed to answer the specific questions of the review. The World Health Organization's International Classification of Functioning Disability and Health was used to map outcomes across the domains. A total of 90 studies were included. The most reported frailty measure was the frailty phenotype. The most reported outcomes were mortality, hospitalisation and healthcare utilisation. Health-related quality of life was the most common patient-reported outcome measure. There were few intervention studies and limited evidence of patient and carer perspectives. This scoping review highlights important areas for further research in older people living with frailty and ACKD. This includes a 'gold standard' measure for identifying frailty, interventions and improvements in outcome measures that matter to patients (including studies that focus on carers and carer burden) and priority setting for future research.

Clinical significance of hemodialysis quality of care indicators in very elderly patients with end stage kidney disease. J Nephrol 2022; 35:2351-2361.

Abstract
INTRODUCTION Improvement in life expectancy has increased the number of very elderly patients undergoing hemodialysis. However, it is not clear which quality measures for hemodialysis should be employed in this population. Therefore, in this paper we investigated the association between major adverse cardiovascular and cerebrovascular events (MACCE) indicators of hemodialysis quality in very elderly patients. PATIENTS AND METHODS: Data regarding a total of 29,692 patients undergoing maintenance hemodialysis (median age 61 years, 41.5% females) who participated in a national hemodialysis quality assessment program were analyzed. They were divided into < 80 years and ≥ 80 years age groups. The primary and secondary outcomes were MACCE and all-cause mortality, respectively. The association between the outcomes and some of the most widely used standard hemodialysis quality-of-care indicators, including spKt/V, hemoglobin, serum calcium, serum phosphate, and albumin levels, was evaluated. To explore the association between Cox proportional hazard models were constructed. Model 1 was adjusted for age and sex. Model 2 included additional demographic characteristics, such as Charlson Comorbidity Index (excluding diabetes), diabetes, cause of ESKD, dialysis vintage, BMI, and pre-dialysis systolic blood pressure. Model 3 was further adjusted for the main medications. To evaluate the relationship between MACCE risk and quality assessment indicators as a continuous variable, cubic spline analyses were conducted. RESULTS During a median follow-up of 3.7 years, MACCE occurred at a higher rate in the ≥ 80-years group than in the < 80-years group (282.0 vs. 110.1 events/1000 person-years). Multivariate Cox regression analysis revealed that spKt/V, serum calcium and phosphate, and hemoglobin levels were associated with MACCE and all-cause mortality risk in patients aged < 80 years. However, these indicators showed no significant relationship with MACCE and all-cause mortality in patients aged ≥ 80 years. Low serum albumin levels were significantly associated with increased MACCE and all-cause mortality risks, regardless of age. CONCLUSION In conclusion, hemodialysis quality-of-care indicators including spKt/V, serum calcium and phosphate levels, and hemoglobin were not related to MACCE or all-cause mortality in very elderly hemodialysis patients. However, lower serum albumin levels were associated with poor outcomes, regardless of patient age. Assuring nutritional status rather than improving hemodialysis management adequacy may be more beneficial for improving outcomes in very elderly hemodialysis patients. Further prospective evaluations are needed to confirm these findings.

Abstract
Background Peritoneal dialysis (PD) is a home-based therapy which requires the patients or their caregivers to perform the practice. We aimed to develop a practical approach to evaluate PD practice ability of the patients and to identify berries to self-care PD. Methods A structural form was designed comprising measures of physical, cognitive, and operational abilities which were required to perform manual PD independently. The evaluation was jointly conducted by a PD nurse, a nephrologist and a close family member of the patient. Patients who met all the requirements were deemed as capable of performing PD independently (self-care PD) and others were deemed as needing an assistant (assisted PD). Results The evaluation form was applied in 280 prevalent PD patients and 33.9% of them were assessed as needing assisted PD, mainly due to physical (62.1%) or operational (66.3%) disabilities. The evaluation result was consistent with current dialysis status in 79.3% patients and it matched better in patients who performed PD with the help of an assistant (93.0 vs. 76.8%, p = 0.014). Patients who were evaluated as having barriers to self-care PD but still performed PD without an assistant were older and demonstrated higher prevalence of diabetic nephropathy and PD-related infection, lower education level, and lower serum albumin (p < 0.05). Conclusions The PD practice ability assessment form is useful to identify patients with barriers to self-care PD. It provides objective information to the patients and their family to choose feasible PD practice modality, self-care, or assisted PD.

Abstract
OBJECTIVE To determine whether a relationship exists between sarcopenia, including its individual components (muscle mass, muscle strength and gait speed), and mild-to-moderate chronic kidney disease (CKD) in Chinese older adults. METHODS This cross-sectional study comprised participants aged ≥60 years from Tianjin and Shanghai, China, who joined a national free physical examination program between 2014 and 2019, and consented to study inclusion. Sarcopenia was defined according to the Asian Working Group for Sarcopenia (2019 version). Mild-to-moderate CKD was defined as estimated glomerular filtration rate (eGFR) between 45 ml/min/1.73 m2 and 60 ml/min/1.73 m2. RESULTS A total of 1627 participants were included (mean age, 69.32 ± 6.17 years; 43.8% male). Sarcopenia was significantly associated with mild-to-moderate CKD in men but not women. Among three physical performance components, slow gait speed (odds ratio 1.89, 95% confidence interval 1.38, 2.58) was associated with mild-to-moderate CKD in both men and women after adjusting for all other variables. CONCLUSIONS Sarcopenia was closely associated with mild-to-moderate CKD in older men, and slow gait speed was related to mild-to-moderate CKD in men and women. These findings may help guide better diagnosis and management of CKD in the context of slow gait speed, and facilitate earlier CKD detection and appropriate intervention in older adults.

[PMID: 36437446 PMCID: PMC9703691 DOI: 10.1186/s13019-022-02043-x] [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: 03/19/2022] [Accepted: 11/20/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND To evaluate the prognostic value of frailty in older recipients of concomitant valve replacement (VR) and bipolar radiofrequency ablation (BRFA), we examined whether clinical and functional outcomes differed between frail and non-frail groups of older patients referred for concomitant VR and BRFA. METHODS In a single-center retrospective observational cohort study, we compared the clinical and functional outcomes in frail versus non-frail patients. Frailty was assessed using the 5-item Cardiovascular Health Study (CHS) frailty scale. Patients were divided into two groups, frail and non-frail. Functional outcome was assessed using the internationally validated Atrial Fibrillation Effect on QualiTy-of-Life (AFEQT) questionnaire. RESULTS We enrolled 185 patients aged ≥ 65 years who underwent concomitant VR and BRFA. About 36.2% (n = 67) of the patients were included in the frail group and the remaining patients (n = 118) in the non-frail group. Follow-up was complete with a median duration of 58 months (interquartile range 44-76 months). Significant differences were observed between the two groups with respect to postoperative pulmonary complications (frail vs. non-frail patients, 50.74% vs. 22.9%, respectively, P < .001) and hospital mortality (10.45% vs. 1.69%, respectively, P = .021). The frail group had a higher adjusted risk for all-cause mortality (adjusted HR 4.06; 95% CI 1.33 to 12.38; P = .014) and all-cause hospitalization (adjusted HR 2.24; 95% CI 1.12 to 4.50; P = .023). Frailty was associated with lower overall AFEQT scores at baseline (Estimate, - 0.400; 95% CI - 0.532 to - 0.267; P < .001). Compared to the non-frail group, the frail group continued to have lower overall AFEQT scores with no significant improvement in follow-up at 1 year and 2 years after concomitant VR and BRFA. CONCLUSION Frail patients had lower baseline AFEQT scores and were more likely to have adverse outcomes from postoperative pulmonary complications, and frailty was also an independent risk factor for long-term all-cause mortality and all-cause rehospitalization. Further studies are needed to assess the impact of frailty.

Chan FHF, Newman S, Khan BA, Griva K. The role of subjective cognitive complaints in self-management among haemodialysis patients: a cross-sectional study. BMC Nephrol 2022; 23:363. [PMID: 36376848 PMCID: PMC9661809 DOI: 10.1186/s12882-022-02994-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 11/01/2022] [Indexed: 11/16/2022] Open
Abstract
Background Subjective cognitive complaints refer to self-experienced difficulties with everyday cognitive tasks. Although there has been a fair amount of research on cognitive impairments and cognitive complaints in end-stage renal disease, the practical implications of these complaints remain unclear. The current study aims to examine the associations of cognitive complaints with sociodemographic and clinical variables, mood, as well as key patient-reported outcomes, i.e., self-efficacy, self-management skills, and treatment adherence. Methods A total of 305 haemodialysis patients (mean age = 53.97 years, 42.6% female) completed the Kidney Disease Quality of Life Cognitive Function subscale, a brief measure of cognitive complaints. The recommended cut-off point of 60 was used to identify probable cognitive impairment. Measures of self-efficacy, self-management skills (i.e., symptom coping, health monitoring, health service navigation), treatment adherence, and mood symptoms were also administered. Between-group comparisons and correlational analyses were performed to examine associations of cognitive complaints with sociodemographic, clinical, and health behaviour variables. Mediation analyses were also conducted to investigate the mediating role of self-efficacy on the relationship between cognitive complaints and treatment adherence. Results Nearly a quarter (23.0%) of haemodialysis patients reported cognitive complaints indicative of clinical impairments. Risk of probable impairments was higher for patients with hypertension, diabetes, those diagnosed with end-stage renal disease at an older age, and those with shorter time on dialysis. Subjective cognitive complaints (both rates of probable impairments as per cut-off and continuous scores) were significantly associated with lower disease and treatment self-efficacy, poorer self-management skills, lower treatment adherence, as well as higher symptoms of distress. Mediation analysis indicated that treatment self-efficacy mediated the relationship between cognitive complaints and treatment adherence. Conclusions The current study demonstrated the clinical characteristics of haemodialysis patients who report cognitive complaints indicative of probable cognitive impairments and showed the associations of these complaints with self-management outcomes. Future studies should adopt more comprehensive measures of cognitive complaints and longitudinal designs to confirm the current findings.

Abstract
Introduction The aim of the Specialised Clinical Frailty Network (SCFN) was to develop frailty-attuned pathways in specialised services in England. Methods We developed a breakthrough series collaborative involving a range of specialised services, using quality improvement methods (including experience-based design) to implement improvements designed to enhance the experience and outcomes of older people living with frailty who have specialised healthcare needs. Results Specialised teams responded positively to the SCFN, many implementing process changes aligned to the needs of older people living with frailty. Some were able to demonstrate improvements in service and/or patient outcomes, including greater identification of frailty, more holistic care and increased use of shared decision making. Discussion The network has successfully demonstrated how frailty can be assessed both at individual, as well as population level, to support both local teams and systems to best manage the health of their patients.

Abstract
In this paper, we have investigated the frailty's prevalence and the association with aging-related health conditions in Chinese community dwelling elderly aged ≥60 years in Lianyungang City of China. In this regard, participants were 1,072 adults aged ≥60 years from Houhe Community of Lianyungang City of China. All the enrolled participants were tested for following parameters: (1) the related risk factors of frailty: including economic status, personal health, understanding and communication skills, and mental and psychological status; (2) aging-related health conditions related to frailty: Charlson's comorbidity index (CCI), Mini Nutritional Assessment Short Form (MNA-SF), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder 7-item (GAD-7); (3) body composition, physical strength, and function testing: appendicular skeletal muscle mass index (ASMI), grip strength, five-repetition sit-to-stand test, 6 m walking speed, and strength assistance rise-climb-fall (SARC-F); (4) assessment of the degree and severity of frailty: physical frailty phenotype (PFP), Morse fall scale (MFS), and activities of daily living (ADL). The frailty's prevalence among the elderly aged ≥60 years in the community of Lianyungang City was 13.8%, 55.4% were prefrail, and 30.8% were robust. The independent risk factors of frailty were age, appendicular skeletal muscle mass index, sarcopenia, education, nutrition, and strength assistance rise-climb-fall (P < 0.05). Aging-related health conditions were associated with frailty, including sarcopenia, nutrition, and falls. However, mental and psychological statuses were not significantly associated with frailty.

Abstract
Purpose This study aimed to compare the plasma levels of nanoparticle-based neurodegenerative biomarkers between hemodialysis (HD) participants with grossly normal cognitive function and healthy controls. Patients and Methods A cohort of participants undergoing maintenance HD and healthy controls were enrolled for comparison between July and October 2021. The immunomagnetic reduction method was used to measure plasma neurodegenerative biomarkers Aβ1-40, Aβ1-42, tau protein, and neurofilament light chain (NfL). The clinical dementia rating (CDR) was used to evaluate cognitive function. A receiver operating characteristic curve was used to discriminate between HD participants and healthy controls. Results There were 52 and 18 participants in the HD and healthy control groups, respectively. The mean age of the HD participants was 62 years, and that of the healthy controls was 57 years. The mean HD vintage in the HD cohort was 11.8 years. HD participants demonstrated significantly higher plasma levels of Aβ1-42, tau protein, Aβ1-42 × tau, and NfL and Aβ1-42/Aβ1-40 ratio and significantly lower plasma Aβ1-40 levels than healthy controls. The measured plasma biomarkers could not discriminate between CDR0 and CDR0.5 HD participants. The area under the curve of the study biomarkers to discriminate HD participants from healthy controls ranged from 0.987 (Aβ1-42 × tau) to 0.889 (NfL). Conclusion The plasma levels of nanoparticle-based neurodegenerative biomarkers were higher in HD participants with grossly normal cognitive function than in healthy controls. These findings imply that neurodegenerative changes appear in HD participants. A profile of plasma neurodegenerative biomarkers could be considered a potential surrogate for evaluating long-term cognitive function in HD participants.

Abstract
INTRODUCTION Availability of assisted PD (asPD) increases access to dialysis at home, particularly for the increasing numbers of older and frail people with advanced kidney disease. Although asPD has been widely used in some European countries for many years, it remains unavailable or poorly utilised in others. A group of leading European nephrologists have therefore formed a group to drive increased availability of asPD in Europe and in their own countries. METHODS Members of the group filled in a proforma with the following headings: personal experience, country experience, who are the assistants, funding of asPD, barriers to growth, what is needed to grow, and their top 3 priorities. RESULTS Only 5 of the 13 countries surveyed provided publicly funded reimbursement for asPD. The use of asPD depends on overall attitudes to PD with all respondents mentioning need for nephrology team education and/or patient education and involvement in dialysis modality decision making. CONCLUSION AND CALL TO ACTION Many people with advanced kidney disease would prefer to have their dialysis at home, yet if the frail patient chooses PD most healthcare systems cannot provide their choice. AsPD should be available in all countries in Europe and for all renal centres. The top priorities to make this happen are education of renal healthcare teams about the advantages of PD, education of and discussion with patients and their families as they approach the need for dialysis, and engagement with policy makers and healthcare providers to develop and support assistance for PD.

Abstract
OBJECTIVE Hemodialysis patients show an approximately threefold higher prevalence of cognitive impairment compared to the age-matched general population. Impaired microcirculatory function is one of the assumed causes. Dynamic retinal vessel analysis is a quantitative method for measuring neurovascular coupling and microvascular endothelial function. We hypothesize that cognitive impairment is associated with altered microcirculation of retinal vessels. METHODS 152 chronic hemodialysis patients underwent cognitive testing using the Montreal Cognitive Assessment. Retinal microcirculation was assessed by Dynamic Retinal Vessel Analysis, which carries out an examination recording retinal vessels' reaction to a flicker light stimulus under standardized conditions. RESULTS In unadjusted as well as in adjusted linear regression analyses a significant association between the visuospatial executive function domain score of the Montreal Cognitive Assessment and the maximum arteriolar dilation as response of retinal arterioles to the flicker light stimulation was obtained. CONCLUSION This is the first study determining retinal microvascular function as surrogate for cerebral microvascular function and cognition in hemodialysis patients. The relationship between impairment in executive function and reduced arteriolar reaction to flicker light stimulation supports the involvement of cerebral small vessel disease as contributing factor for the development of cognitive impairment in this patient population and might be a target for noninvasive disease monitoring and therapeutic intervention.

Abstract
An increasing number of older patients have to decide on a treatment plan for advanced chronic kidney disease (CKD), involving dialysis or conservative care. Shared decision-making (SDM) is recommended as the model for decision-making in such preference-sensitive decisions. The aim of SDM is to come to decisions that are consistent with the patient’s values and preferences and made by the patient and healthcare professional working together. In clinical practice, however, SDM appears to be not yet routine and needs further implementation. A shift from a biomedical to a person-centered conception might help to make the process more shared. Shared should, therefore, be interpreted as two persons bringing two perspectives to the table, that both need to be explored during the decision-making process. Starting from the patient’s perspective will enable to determine the mutual goals of care first and, subsequently, determine the best way for achieving those goals. To perform such SDM, the healthcare professional needs to become a skilled companion, being part of the patient’s relational context, and start asking the right questions about what matters to the patient as person. In this article, we describe the need for a person-centered conception of SDM for the setting of older patients with advanced CKD.

Abstract
BACKGROUND The influence of exercise on cognition in patients undergoing haemodialysis has been examined. However, evidence elucidating the effects in this patient group is scarce. OBJECTIVE To examine the effect of exercise on cognitive impairment in patients undergoing haemodialysis and provide insight into the effects of various characteristics of exercise on cognitive impairment in this population. DESIGN A systematic review and meta-analysis, following the guidance of PRISMA was undertaken. PARTICIPANTS Adult patients undergoing haemodialysis. RESULTS This review found that exercise significantly improved cognitive impairment in patients undergoing haemodialysis (SMD = 0.37, 95% CI: 0.13, 0.60, p = 0.002). Subgroup analyses demonstrated that both intradialytic exercise (SMD = 0.82, 95% CI: 0.37, 1.26, p < 0.001) and interdialytic exercise (SMD = 0.24, 95% CI: 0.01, 0.47, p = 0.038), exercise for 16 weeks or over (SMD = 0.33, 95% CI: 0.07, 0.58, p = 0.012), and lasting for more than 30 minutes (SMD = 0.52, 95% CI: 0.17, 0.86, p = 0.004) significantly alleviated cognitive impairment. The effect of exercise on cognitive impairment in patients less than 65 years of age (SMD = 0.39, 95% CI: 0.10, 0.68, p = 0.009) was significantly better than those over 65. CONCLUSION Exercise significantly improves cognitive impairment in patients undergoing haemodialysis. Both Intradialytic and interdialytic exercise of at least 30 minutes duration, 3 times weekly, and at least for 16 weeks may play a significant role in alleviating cognitive impairment in patients under 65 years of age.

Abstract
BACKGROUND Elderly peritoneal dialysis (PD) patients required assistance for a variety of PD-related tasks. The usefulness of assisted PD in reducing the peritonitis risk has been reported; however, there is little evidence on the effectiveness of assisted PD in preventing exit-site infections in older patients. METHODS This was a single-center, prospective cohort study. Thirty-three patients (mean age: 74.8 ± 5.9 years) on PD were evaluated for cognitive impairment (CI) using the Japanese version of the Montreal Cognitive Assessment. They were also evaluated to determine whether they performed the exit-site care procedure alone or with assistance. Patients were categorized into four groups based on the presence or absence of CI and the presence or absence of exit-site care assistance. They were followed up until the occurrence of peritonitis and exit-site infection at the end of the follow-up. RESULTS Altogether, 8, 8, and 17 patients were assigned to the "without CI and without assistance", "without CI and with assistance", and "with CI and with assistance groups", respectively; no patients were assigned to the "with CI and without assistance group". Six and 16 patients experienced peritonitis and exit-site infection during follow-up, respectively. Kaplan-Meier analysis and log-rank tests revealed that the "without CI and without assistance group" was significantly associated with exit-site infection (log-rank < 0.05). CONCLUSION Patients who did not receive assistance for exit-site care were at a higher risk of exit-site infections, even in the absence of CI. Caregiver assistance is important for preventing exit-site infections in older patients on PD.

Association Between Functional Limitations and Incident Cardiovascular Diseases and All-Cause Mortality Among the Middle-Aged and Older Adults in China: A Population-Based Prospective Cohort Study. Front Public Health 2022; 10:751985. [PMID: 35223720 PMCID: PMC8873112 DOI: 10.3389/fpubh.2022.751985] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 01/07/2022] [Indexed: 11/26/2022] Open
Abstract
Background The prevalence of functional limitations is relatively high among the middle-aged and older adults. However, the contribution of functional limitations to subsequent incident cardiovascular diseases (CVD) and death is unclear. This study aims to examine the association between functional limitations and incident CVD and all-cause mortality among the middle-aged and older adults. Methods This is a nationally representative prospective cohort study. Participants were middle-aged and older Chinese adults from The China Health and Retirement Longitudinal Study. Functional limitations were measured using activities of daily living (ADL) scale and instrumental activities of daily living (IADL) scale. Incident CVD and death were recorded at followed-up from June 1, 2011, up until August 31, 2018. Cox proportional hazards model was used to assess the association between functional limitations and incident CVD and all-cause mortality. Results A total of 11,013 participants were included in this study. During the 7 years of follow-up, 1,914 incident CVD and 1,182 incident deaths were identified. Participants with functional limitations were associated with a 23% increased risk of incident CVD (HR, 1.23, 95% CI:1.08,1.39) after adjusting for age, gender, residential area, marital status, education, smoking, alcohol drinking, sleep duration, nap duration, depression symptoms, social participation, history of hypertension, diabetes, dyslipidemia, use of hypertension medications, diabetes medications, and lipid-lowering therapy. Moreover, participants with functional limitations were associated with a 63% increased risk of all-cause mortality (HR,1.63, 95%CI: 1.41,1.89) after adjusting for potential confounders. Conclusions Functional limitations were significantly associated with subsequent incident CVD and death among the middle-aged and older Chinese adults.

Converting from face-to-face to postal follow-up and its effects on participant retention, response rates and errors: lessons from the EQUAL study in the UK. BMC Med Res Methodol 2022; 22:44. [PMID: 35148682 PMCID: PMC8832416 DOI: 10.1186/s12874-021-01453-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Accepted: 10/28/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Prospective cohort studies are challenging to deliver, with one of the main difficulties lying in retention of participants. The need to socially distance during the COVID-19 pandemic has added to this challenge. The pre-COVID-19 adaptation of the European Quality (EQUAL) study in the UK to a remote form of follow-up for efficiency provides lessons for those who are considering changing their study design. METHODS The EQUAL study is an international prospective cohort study of patients ≥65 years of age with advanced chronic kidney disease. Initially, patients were invited to complete a questionnaire (SF-36, Dialysis Symptom Index and Renal Treatment Satisfaction Questionnaire) at research clinics every 3-6 months, known as "traditional follow-up" (TFU). In 2018, all living patients were invited to switch to "efficient follow-up" (EFU), which used an abbreviated questionnaire consisting of SF-12 and Dialysis Symptom Index. These were administered centrally by post. Response rates were calculated using returned questionnaires as a proportion of surviving invitees, and error rates presented as the average percentage of unanswered questions or unclear answers, of total questions in returned questionnaires. Response and error rates were calculated 6-monthly in TFU to allow comparisons with EFU. RESULTS Of the 504 patients initially recruited, 236 were still alive at the time of conversion to EFU; 111 of these (47%) consented to the change in follow-up. In those who consented, median TFU was 34 months, ranging from 0 to 42 months. Their response rates fell steadily from 88% (98/111) at month 0 of TFU, to 20% (3/15) at month 42. The response rate for the first EFU questionnaire was 60% (59/99) of those alive from TFU. With this improvement in response rates, the first EFU also lowered errors to baseline levels seen in early follow-up, after having almost trebled throughout traditional follow-up. CONCLUSIONS Overall, this study demonstrates that administration of shorter follow-up questionnaires by post rather than in person does not negatively impact patient response or error rates. These results may be reassuring for researchers who are trying to limit face-to-face contact with patients during the COVID-19 pandemic.

Age at Time of Kidney Transplantation as a Predictor for Mortality, Graft Loss and Self-Rated Health Status: Results From the Swiss Transplant Cohort Study. Transpl Int 2022; 35:10076.

Abstract
Introduction: The effect of age on health outcomes in kidney transplantation remains inconclusive. This study aimed to analyze the relationship between age at time of kidney transplantation with mortality, graft loss and self-rated health status in adult kidney transplant recipients. Methods: This study used data from the Swiss Transplant Cohort Study and included prospective data of kidney transplant recipients between 2008 and 2017. Time-to-event analysis was performed using Cox’ regression analysis, and -in the case of graft loss- competing risk analysis. A random-intercept regression model was applied to analyse self-rated health status. Results: We included 2,366 kidney transplant recipients. Age at transplantation linearly predicted mortality. It was also predictive for graft loss, though nonlinearly, showing that recipients aged between 35 and 55 years presented with the lowest risk of experiencing graft loss. No relationship of age with self-rated health status was detected. Conclusion: Higher mortality in older recipients complies with data from the general population. The non-linear relationship between age and graft loss and the higher scored self-rated health status at all follow-up time-points compared to the pre-transplant status -regardless of age- highlight that age alone might not be an accurate measure for risk prediction and clinical decision making in kidney transplantation.

Transplant centers that assess frailty as part of clinical practice have better outcomes. BMC Geriatr 2022; 22:82. [PMID: 35086480 PMCID: PMC8793239 DOI: 10.1186/s12877-022-02777-2] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Accepted: 01/17/2022] [Indexed: 01/16/2023] Open
Abstract
BACKGROUND Frailty predicts adverse post-kidney transplant (KT) outcomes, yet the impact of frailty assessment on center-level outcomes remains unclear. We sought to test whether transplant centers assessing frailty as part of clinical practice have better pre- and post-KT outcomes in all adult patients (≥18 years) and older patients (≥65 years). METHODS In a survey of US transplant centers (11/2017-4/2018), 132 (response rate = 65.3%) centers reported their frailty assessment practices (frequency and specific tool) at KT evaluation and admission. Assessment frequency was categorized as never, sometime, and always; type of assessment tool was categorized as none, validated (for post-KT risk prediction), and any other tool. Center characteristics and clinical outcomes for adult patients during 2017-2019 were gleaned from the transplant national registry (Scientific Registry of Transplant Recipients). Poisson regression was used to estimate incidence rate ratios (IRRs) of waitlist outcomes (waitlist mortality, transplantation) in candidates and IRRs of post-KT outcomes (all-cause mortality, death-censored graft loss) in recipients by frailty assessment frequency. We also estimated IRRs of waitlist outcomes by type of assessment tool at evaluation. All models were adjusted for case mix and center characteristics. RESULTS Assessing frailty at evaluation was associated with lower waitlist mortality rate (always IRR = 0.91,95%CI:0.84-0.99; sometimes = 0.89,95%CI:0.83-0.96) and KT rate (always = 0.94,95%CI:0.91-0.97; sometimes = 0.88,95%CI:0.85-0.90); the associations with waitlist mortality rate (always = 0.86,95%CI:0.74-0.99; sometimes = 0.83,95%CI:0.73-0.94) and KT rate (always = 0.82,95%CI:0.77-0.88; sometimes = 0.92,95%CI:0.87-0.98) were stronger in older patients. Furthermore, using validated (IRR = 0.90,95%CI:0.88-0.92) or any other tool (IRR = 0.90,95%CI:0.87-0.93) at evaluation was associated lower KT rate, while only using a validated tool was associated with lower waitlist mortality rate (IRR = 0.89,95%CI:0.83-0.96), especially in older patients (IRR = 0.82,95%CI:0.72-0.93). At admission for KT, always assessing frailty was associated with a lower graft loss rate (IRR = 0.71,95%CI:0.54-0.92) but not with mortality (IRR = 0.93,95%CI:0.76-1.13). CONCLUSIONS Assessing frailty at evaluation is associated with lower KT rate, while only using a validated frailty assessment tool is associated with better survival, particularly in older candidates. Centers always assessing frailty at admission are likely to have better graft survival rates. Transplant centers may utilize validated frailty assessment tools to secure KT access for appropriate candidates and to better allocate health care resources for patients identified as frail, particularly for older patients.

Abstract
Background Non-dialytic conservative care (CC) has been proposed as a treatment option for patients with kidney failure. This systematic review and meta-analysis aims at comparing survival outcomes between dialysis and CC in studies where patients made an explicit treatment choice. Methods Five databases were systematically searched from origin through 25 February 2021 for studies comparing survival outcomes among patients choosing dialysis versus CC. Adjusted and unadjusted survival rates were extracted and meta-analysis performed where applicable. Risk of bias analysis was performed according to the Cochrane Risk Of Bias In Non-randomized Studies of Interventions. Results A total of 22 cohort studies were included covering 21 344 patients. Most studies were prone to selection bias and confounding. Patients opting for dialysis were generally younger and had fewer comorbid conditions, fewer functional impairments and less frailty than patients who chose CC. The unadjusted median survival from treatment decision or an estimated glomerular filtration rate <15 mL/min/1.73 m2 ranged from 20 and 67 months for dialysis and 6 and 31 months for CC. Meta-analysis of 12 studies that provided adjusted hazard ratios (HRs) for mortality showed a pooled adjusted HR of 0.47 (95% confidence interval 0.39–0.57) for patients choosing dialysis compared with CC. In subgroups of patients with older age or severe comorbidities, the reduction of mortality risk remained statistically significant, although analyses were unadjusted. Conclusions Patients opting for dialysis have an overall lower mortality risk compared with patients opting for CC. However, a high risk of bias and heterogeneous reporting preclude definitive conclusions and results cannot be translated to an individual level.

Abstract
BACKGROUND Frailty has been associated with mortality and adverse cardiovascular outcomes in patients with hemodialysis (HD), however the relevance of frailty on the outcomes of HD vascular access remains unclear. METHODS We enrolled a cohort of patients with prevalent HD between August 2018 and November 2018. The presence of 5 frailty phenotypes was determined at enrollment, using the modified Fried's criteria. Data regarding vascular access events or mortality were linked to prospectively collected data up to 24 months after enrollment. RESULTS Of the 382 patients screened, 313 were recruited in the final analysis. The participants' mean age was 66 years, and 42.5% were female. Among all participants, 40.3% were determined to be frail and 29.4% pre-frail. The frail phenotype was associated with age, female gender, lower body mass index, unemployment, lower education level, and higher dialysis clearance. During the follow-up period (median, 24 months), 112 patients had vascular access events (non-frail, 27.4%; pre-frail, 35.9%; frail, 46.1%; p = 0.003) and 45 patients experienced thrombosis of the vascular access (non-frail, 4.2%; pre-frail, 9.8%; frail, 18.3%; p = 0.002). Cox regression analysis showed that frail patients had a 2.2-fold higher risk of experiencing vascular access events than non-frail patients [hazard ratio (HR): 2.205, 95% confidence interval (CI): 1.377-3.532, p = 0.001], but the association was not significant (HR: 1.634, 95% CI: 0.938-2.848, p = 0.082) after multivariate adjustment. CONCLUSIONS The frail phenotype is common in Taiwanese patients who undergo maintenance HD and is associated with adverse outcomes of dialysis vascular access.

Abstract
The number of patients ≥65 years of age suffering from advanced chronic kidney disease and transitioning to end-stage kidney disease (ESKD) is increasing. However, elderly patients often have poor outcomes once haemodialysis is initiated, including high mortality within the first year as well as fast cognitive and functional decline and diminished quality of life. The question is how we can smooth this transition to ESKD in older patients who also exhibit much higher proportions of frailty when compared with community-dwelling non-dialysis older adults and who are generally more vulnerable to invasive treatment such as kidney replacement therapy. To avoid early death and poor quality of life, a carefully prepared smooth transition should precede the initiation of treatment. This involves pre-dialysis physical and educational care, as well as mental and psychosocial preparedness of the patient to enable an informed and shared decision about the individual choice of treatment modality. Communication between a healthcare professional and patient plays a pivotal role but can be challenging given the high rate of cognitive impairment in this particular population. In order to practise patient-centred care, adapting treatment tailored to the individual patient should include comprehensive conservative care. However, structured treatment pathways including multidisciplinary teams for such conservative care are still rare and may be difficult to establish outside of large cities. Generally, geriatric nephrology misses data on the comparative effectiveness of different treatment modalities in this population of old and very old age on which to base recommendations and decisions.

Abstract
BACKGROUND Cognitive impairment is common among persons with chronic kidney disease (CKD) due in part to reduced kidney function. Given that physical activity (PA) is known to mitigate cognitive decline, we examined whether associations between CKD stage and global/domain-specific cognitive function differs by PA. METHODS We leveraged 3,223 participants (aged≥60years) enrolled in National Health and Nutrition Examination Survey (NHANES,2011-2014), with at least one measure of objective cognitive function (immediate recall [CERAD-WL], delayed recall [CERAD-DR], verbal fluency [AF], executive function/processing speed [DSST], global [average of 4 tests]) or self-perceived memory decline [SCD]. We quantified the association between CKD stage (no CKD: eGFR≥60 mL/min/1.73m2 and albuminuria(ACR)<30 mg/g; stage G1-G3: eGFR≥60mL/min/1.73m2 and ACR≥30mg/g or eGFR 30-59mL/min/1.73m2; stage G4-G5: eGFR<30mL/min/1.73m2) and cognitive function using linear regression (objective measures) and logistic regression (SCD), accounting for sampling weights for nationally-representative estimates. We tested whether associations differed by physical activity (Global Physical Activity Questionnaire, high PA≥600MET*min/week vs. low PA<600MET*min/week) using a Wald test. RESULTS Among NHANES participants, 34.9% had CKD stageG1-G3, 2.6% had stageG4-G5, and 50.7% had low PA. CKD stageG4-G5 was associated with lower global cognitive function (difference = -0.38SD, 95%CI:-0.62,-0.15). This association differed by PA (pinteraction = 0.01). Specifically, among participants with low PA, those with CKD stageG4-G5 had lower global cognitive function (difference = -0.57SD, 95%CI: -0.82,-0.31) compared to those without CKD. Among those with high PA, no difference was found (difference = 0.10SD, 95%CI:-0.29,0.49). Similarly, CKD stage was only associated with immediate recall, verbal fluency, executive function, and processing speed among those with low PA; no associations were observed for delayed recall or self-perceived memory decline. CONCLUSIONS CKD is associated with lower objective cognitive function among those with low, but not high PA. Clinicians should consider screening older patients with CKD who have low PA for cognitive impairment and encourage them to meet PA guidelines.

Prevalence of cognitive impairment in Chinese older inpatients and its relationship with 1-year adverse health outcomes: a multi-center cohort study. BMC Geriatr 2021; 21:595. [PMID: 34696723 PMCID: PMC8543818 DOI: 10.1186/s12877-021-02556-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 10/12/2021] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND Previous studies on the relationship between cognitive impairment and adverse outcomes among geriatric inpatients are not representative of older inpatients in China because of insufficient sample sizes or single-center study designs. The purpose of our study was to examine the prevalence of cognitive impairment and the relationship between cognitive impairment and 1-year adverse health outcomes in older inpatients. METHODS This study was a large-scale multi-center cohort study conducted from October 2018 to February 2020. Six tertiary hospitals across China were selected using a two-stage cluster sampling method, and eligible older inpatients were selected for the baseline survey and follow-up. The Mini Cognitive Scale and the FRAIL scale were used to screen for cognitive impairment and frailty, respectively. The EuroQol-5 Dimension-5 Level questionnaire was used to assess health-related quality of life (HRQoL). We used a generalized estimating model to evaluate the relationship between cognitive impairment and adverse outcomes. RESULTS The study included 5008 men (58.02%) and 3623 women (41.98%), and 70.64% were aged 65-75 years, and 26.27% were aged 75-85 years. Cognitive impairment was observed in 1756 patients (20.35%). There were significant differences between participants with cognitive impairment and those with normal cognitive function for age, gender, surgery status, frailty, depression, handgrip strength and so on. After adjusting for multiple covariates, compared with patients with normal cognitive function, the odds ratio for 1-year mortality was 1.216 (95% confidence interval [CI]: 1.076-1.375) and for 1-year incidence of frailty was 1.195 (95% CI: 1.037-1.376) in patients with cognitive impairment. Similarly, the regression coefficient of 1-year HRQoL was - 0.013 (95% CI: - 0.024-- 0.002). In the stratified analysis, risk of adverse outcome within 1 year was higher in older patients with cognitive impairment aged over 75 years than those aged 65-74 years. CONCLUSIONS We revealed that cognitive impairment was highly correlated with occurrence of 1-year adverse health outcomes (death, frailty, and decreased HRQoL) in older inpatients, which provides a basis for formulating effective intervention measures.

Am J Kidney Dis 2021; 79:699-708.e1. [PMID: 34648897 DOI: 10.1053/j.ajkd.2021.08.019] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Accepted: 08/11/2021] [Indexed: 11/11/2022]
Abstract
RATIONALE AND OBJECTIVE Although guidelines recommend more and earlier advance care planning (ACP) for patients with chronic kidney disease (CKD), scant evidence exists to guide incorporation of ACP into clinical practice for patients not yet requiring maintenance dialysis. Involving nephrology team members in addition to primary care providers in this important patient-centered process may increase its accessibility. Our objective was to examine the effect of coaching implemented in CKD clinics on patient engagement with ACP. STUDY DESIGN Multicenter, pragmatic randomized control trial. SETTING & PARTICIPANTS Three CKD clinics in different states participated. Eligible patients were 55 years or older, had stage 3-5 CKD, and were English speaking. 273 patients consented to participate, 254 were included in analysis. INTERVENTION Nurses or social workers with experience in nephrology or palliative care delivered individualized in-person ACP sessions. The enhanced control group was given Make Your Wishes About You (MY WAY) education materials and was verbally encouraged to bring their completed advance directives to the clinic. OUTCOMES Primary outcome measures were scores on a 45-point ACP engagement scale at 14 weeks and a documented advance directive or portable medical order at 16 weeks post-enrollment. RESULTS Among 254 participants analyzed, 46.5% were 65-74 years of age and 54% had CKD stage 3. Coached patients scored 1.9 points higher at 14 weeks on the ACP engagement scale (β = 1.87; CI: 0.13-3.64) adjusted for baseline score and site. Overall, 32.8% of intervention patients (41 of 125) had an advance directive compared to 17.8% (23 of 129) of patients in the comparison group. In a site-adjusted multivariable model, coached patients were 79% more likely to have a documented advance directive or portable medical order (adjusted risk ratio = 1.79; 95% CI: 1.18-2.72), with the impact principally evident at only one study site. LIMITATIONS Small number of study sites and possible unrepresentativeness of the broader CKD population by study participants. CONCLUSIONS AND RELEVANCE Individualized coaching may be effective in enhancing ACP but its impact may be influenced by the healthcare environment where it is delivered.

Frailty Is Independently Associated with Mortality and Readmission in Hospitalized Patients with Inflammatory Bowel Diseases. Clin Gastroenterol Hepatol 2021; 19:2054-2063.e14. [PMID: 32801013 PMCID: PMC7930013 DOI: 10.1016/j.cgh.2020.08.010] [Citation(s) in RCA: 48] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 07/27/2020] [Accepted: 08/07/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Old age must be considered in weighing the risks of complications vs benefits of treatment for patients with inflammatory bowel diseases (IBD). We conducted a nationally representative cohort study to estimate the independent effects of frailty on burden, costs, and causes for hospitalization in patients with IBD. METHODS We searched the Nationwide Readmissions Database to identify 47,402 patients with IBD, hospitalized from January through June 2013 and followed for readmission through December 31, 2013. Based on a validated hospital frailty risk scoring system, 15,507 patients were considered frail and 31,895 were considered non-frail at index admission. We evaluated the independent effect of frailty on longitudinal burden and costs of hospitalization, inpatient mortality, risk of readmission and surgery, and reasons for readmission. RESULTS Over a median follow-up time of 10 months, adjusting for age, sex, income, comorbidity index, depression, obesity, severity, and indication for index hospitalization, frailty was independently associated with 57% higher risk of mortality (adjusted hazard ratio [aHR], 1.57; 95% CI, 1.34-1.83), 21% higher risk of all-cause readmission (adjusted hazard ratio [HR], 1.21; 95% CI, 1.17-1.25), and 22% higher risk of readmission for severe IBD (aHR, 1.22; 95% CI, 1.16-1.29). Frail patients with IBD spent more days in the hospital annually (median 9 days; interquartile range, 4-18 days vs median 5 days for non-frail patients; interquartile range, 3-10 days; P < .01) with higher costs of hospitalization ($17,791; interquartile range, $8368-$38,942 vs $10,924 for non-frail patients, interquartile range, $5571-$22,632; P < .01). Infections, rather than IBD, were the leading cause of hospitalization for frail patients. CONCLUSIONS Frailty is independently associated with higher mortality and burden of hospitalization in patients with IBD; infections are the leading cause of hospitalization. Frailty should be considered in treatment approach, especially in older patients with IBD.

Abstract
Background Dementia is prevalent and underdiagnosed in the dialysis population. We aimed to develop and validate a simple dialysis dementia scoring system to facilitate identification of individuals who are at high risk for dementia. Methods We applied a retrospective, nested case‐control study design using a national dialysis cohort derived from the National Health Insurance Research Database in Taiwan. Patients aged between 40 and 80 years were included and 2940 patients with incident dementia were matched to 29,248 non‐dementia controls. All subjects were randomly divided into the derivation and validation sets with a ratio of 4:1. Conditional logistic regression models were used to identify factors contributing to the risk score. The cutoff value of the risk score was determined by Youden's J statistic and the graphic method. Results The dialysis dementia risk score (DDRS) finally included age and 10 comorbidities as risk predictors. The C‐statistic of the model was 0.71 (95% confidence interval [CI] 0.70–0.72). Calibration revealed a strong linear relationship between predicted and observed dementia risk (R2 = 0.99). At a cutoff value of 50 points, the high‐risk patients had an approximately three‐fold increased risk of having dementia compared to those with low risk (odds ratio [OR] 3.03, 95% CI 2.78–3.31). The DDRS performance, including discrimination (C‐statistic 0.71, 95% CI 0.69–0.73) and calibration (p value of Hosmer−Lemeshow test for goodness of fit = 0.18), was acceptable during validation. The OR value (2.82, 95% CI 2.37–3.35) was similar to those in the derivation set. Conclusion The DDRS system has the potential to serve as an easily accessible screening tool to determine the high‐risk groups who deserve subsequent neurological evaluation in daily clinical practice.

Abstract
AIM To evaluate the cognitive function in dialysis patients over 60 years old and identify the contributing factors. METHODS A group of elderly dialysis patients in the Department of Nephrology, Pan'an People's Hospital between March 2015 and June 2018 were chosen as the subjects for this study. Patients were divided into two groups, those with cognitive impairment and those with normal cognitive function. Results of their Montreal Cognitive Assessment (MoCA) scores, Controlled Oral Word Association Test (COWAT), Wechsler Adult Intelligence Scale Digit Span subtest (WDMS), and Stanford Diagnostic Math Test (SDMT) were reviewed and analyzed. RESULTS Among the 110 elderly dialysis patients, 75 patients (68.18%) showed different levels of damage to their cognitive function. Their assessment scores on MoCA (total), MoCA subtests: visuospatial/executive, naming, attention, language, delayed recall, abstraction and orientation, COWAT (total), COWAT1, COWAT2, COWAT3, WMDS-Backward, and SDMT are significantly lower than patients with normal cognitive abilities (p < 0.05). Further analysis showed that the highest percentage (72.00%) of patients had impairment with visuospatial/executive function; and, of the 75 cognitive impaired patients, 37.33% showed cognitive damage in two MoCA subtests simultaneously. Patients with and without cognitive impairment showed a significant (p < 0.05) difference on factors including age, education level, employment status, financial situation, dialysis vintage, serum albumin, and hemoglobin. CONCLUSION Elderly patients on dialysis have a higher risk of becoming cognitive impaired. The cognitive impairment in elderly dialysis patients was significantly associated with age, dialysis vintage, and levels of serum albumin and hemoglobin.

Abstract
RATIONALE & OBJECTIVE Social support in older adults with chronic kidney disease (CKD) is a potentially modifiable factor that may affect important clinical outcomes such as health-related quality of life, cognitive function, and frailty. However, limited data about the effects of social support in older patients with non-dialysis-dependent CKD exist. Our objective was to evaluate the association of social support with health-related quality of life, cognitive function, and frailty in older adults with CKD. STUDY DESIGN Cross-sectional analysis of a prospective cohort study. SETTING & POPULATION 1,851 participants older than 65 years with CKD enrolled in the Chronic Renal Insufficiency Cohort (CRIC) Study. EXPOSURE Social support (Lubben Social Network Scale [LSNS]). OUTCOMESS Health-related quality of life (Kidney Disease Quality of Life-36), cognitive function (Modified Mini-Mental State Examination, Trail Making Test A & B, and Buschke Selective Reminder Tests), and frailty (modified Fried frailty criteria). ANALYTIC APPROACH Multivariable, linear, and logistic regression to determine the association between social support and health-related quality of life, cognitive function, and frailty. RESULTS Low social support, defined as LSNS score < 12, was present in 22% of participants. On multivariable analysis, higher social support was associated with higher health-related quality of life (β coefficient per 1-SD increase in LSNS score; burden subscale, 2.57 (95% CI, 1.57-3.56); effects subscale, 2.21 (95% CI, 1.52-2.9); symptoms subscale, 1.64 (95% CI, 0.88-2.41); mental health composite subscale, 1.91 (95% CI, 1.40-2.43); and physical health composite score, 0.64 (95% CI, 0.03-1.24)). Higher social support was associated with better cognitive function (β coefficient per 1-SD increase in LSNS score; Modified Mini-Mental State Examination, 0.81 (95% CI, 0.44 to 1.19); Trail Making Test A & B, -2.53 (95% CI, -4.29 to -0.76) and -6.53 (95% CI, -10.07 to -2.99), respectively; Buschke Selective Reminder Test 1, 2, and 3, 0.19 (95% CI, 0.07 to 0.30); 1.59 (95% CI, 0.96 to 2.22); and 0.40 (95% CI, 0.23 to 0.56), respectively. Higher social support was associated with higher likelihood of being nonfrail (OR, 1.77; 95% CI per 1-SD higher LSNS score, 1.24-2.53). LIMITATIONS Conclusions about causality cannot be drawn from an observational cross-sectional study. CONCLUSIONS In older patients with CKD, higher social support was associated with higher health-related quality of life and cognitive function and less frailty.
