Patient-Reported Outcome Instruments for Physical Symptoms Among Patients Receiving Maintenance Dialysis: A Systematic Review

Pharmacological Treatment for Dialysis-Related Muscle Cramps: A Systematic Review

BACKGROUND

Patients with end-stage renal disease undergoing dialysis suffer from muscle cramps, a prevalent and burdensome symptom for which there is a paucity of efficient and safe treatments.

AIM

What is the efficacy and safety of pharmacological interventions for the treatment of dialysis-related muscle cramps?

DESIGN

A systematic review was conducted in OVID, CINAHL, PubMed, Web of Science, and Central Cochrane databases up to August 25, 2023.

DATA SOURCES

Experimental studies reporting on a pharmacological intervention for the treatment of dialysis-related muscle cramps were included. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis, and the studies quality was assessed with the RoB2 tool.

RESULTS

A total of 4660 studies were retrieved, and 13 articles were included. The studies reported on nine interventions: vitamin C, vitamin E, vitamin K2, vitamin B7, dextrose solutions, gabapentin, sodium chloride, creatine monohydrate, and L-carnitine. The studies testing L-carnitine and creatine monohydrate were the only ones deemed to have a low risk of bias. Side effects were reported in only two trials, consisting primarily of gastrointestinal discomfort and hyperglycemia. Vitamins C and E are the two most studied interventions that showed positive results in reducing the frequency, severity, and duration of dialysis-related muscle cramps. L-carnitine is a promising intervention that warrants further investigation.

CONCLUSION

Our review consolidates the existing evidence, elucidating the range of treatments along with their potential benefits and limitations. Future studies should uphold high-quality standards, incorporate patient-reported outcomes, and utilize well-defined, robust samples to improve patient care.

Symptom Science in Kidney Disease

Physical and emotional symptoms are highly prevalent among patients with kidney disease and are directly linked to impaired health-related quality of life. Symptom science is a field of research aimed at advancing knowledge of the holistic mechanisms driving symptoms, how best to assess symptoms accurately, and developing novel and patient-centered approaches to symptom management. Patients with kidney disease have identified symptom science as a top research priority, and opportunities abound for ongoing patient engagement in symptom-related research efforts and clinical care. This review describes the burden of symptoms experienced by patients with kidney disease, explores the spectrum of patient engagement in symptom care and research, and discusses approaches for symptom assessment and management, taking into consideration the multitude of factors that may contribute to symptoms.

The Scale of Perceptions and Self-Participation in Hemodialysis: Development and Psychometric Evaluation

Hemodialysis patients undergo hemodialysis two to three times a week and must live together with the dialysis machine. The patient's self-participation is to combine the patient's own experience and professional knowledge to influence the care. A successful self-participation experience empowers patients to adapt to living with hemodialysis. However, few studies have been conducted regarding the subjective experiences of such patient participation. There is a lack of a self-participation dialysis life scale for hemodialysis patients. Therefore, this study aims to develop and evaluate a self-participation dialysis life scale for hemodialysis patients. The items for the self-participation dialysis life scale were confirmed through qualitative interviews based on grounded theory. After expert content validity evaluation, 435 hemodialysis patients were purposively sampled from hemodialysis centers in two regional teaching hospitals in Taiwan. Descriptive statistics, principal axis factoring, reliability analysis, Pearson's correlation, and one-way ANOVA were used for data analysis. The results show that the item- and scale-content validity indices are 0.96 and 0.73, respectively. This scale is divided into two scales. The first part is "Scale of Perceptions of Hemodialysis", including two factors. The overall can explain 66.34% of the cumulative variances. The second part is the "Scale of Self-Participation in Hemodialysis", including four factors. The overall can explain 58.91% of the cumulative variances. The Cronbach's α is 0.812 for "Perceptions of Hemodialysis" and 0.959 for "Self-Participation in Hemodialysis", respectively. The self-participation dialysis life scale has good reliability and validity and can be used to evaluate the implementation of a patient's self-participation in their hemodialysis life. Discussing or consulting with patients based on their characteristics, life priorities, and their desired life on dialysis is essential for a high-quality of clinical care among hemodialysis patients.

Factors Related to Quality of Life of Hemodialysis Patients during the COVID-19 Pandemic

Taiwan had the second highest number globally of end-stage renal disease patients undergoing treatment in 2018. A meta-analysis of Chen et al. (2021) showed the incidence and mortality rates of COVID-19 were 7.7% and 22.4%, respectively. Few studies have explored the effects of patients' self-participation and perceptions of hemodialysis on their quality of life. This study aimed to explore the factors related to hemodialysis patients' quality of life during the COVID-19 pandemic. This study was a descriptive correlational study. Patients were recruited (n = 298) from the hemodialysis unit of a medical center in northern Taiwan. Variables included patients' sociodemographic, psychological, spiritual, and clinical characteristics (i.e., perceived health level, comorbidities, hemodialysis duration, weekly frequency, transportation, and accompaniment during hemodialysis), perceptions of hemodialysis, self-participation in hemodialysis, and health-related quality of life (KDQOL-36 scale). Data were analyzed using descriptive and bivariate and multivariate linear regression. Multivariate linear regression, after adjusting for covariates, showed that anxiety, self-perceived health status, two vs. four comorbidities, and self-participation in hemodialysis were significantly associated with quality of life. The overall model was significant and accounted for 52.2% (R² = 0.522) of the variance in quality of life during hemodialysis (adjusted R² = 0.480). In conclusion, the quality of life of hemodialysis patients with mild, moderate, or severe anxiety was poorer, whereas that of patients with fewer comorbidities, higher self-perceived health status, and higher self-participation in hemodialysis was better.

Physical intradialytic patient-reported outcome measures in haemodialysis and haemodiafiltration: A cross-over study

AIM

Standard haemodialysis (sHD) is associated with a poor survival and marked adverse intradialytic patient-reported outcome measures (ID-PROMs). Whereas physical ID-PROMs (PID-PROMs) are alleviated by cool dialysate (cHD), survival is prolonged by haemodiafiltration (HDF). So far, PID-PROMs are not prospectively compared between HD and HDF.

METHODS

To assess whether PID-PROMs and thermal perception differ between sHD, cHD, low volume HDF (lvHDF) and high volume HDF (hvHDF), 40 patients were cross-over randomized to each modality for 2 weeks. Dialysate temperature (T_d ) was 36.5°C, except in cHD (T_d 35.5°C). Target convection volumes were 15 L in lvHDF and ≥ 23 L in hvHDF. PID-PROMs were evaluated with a modified Dialysis Symptom Index (mDSI) and thermal perception with the Visual Analogue Scale Thermal Perception (VAS-TP). T_b and room temperature were measured as well.

RESULTS

Except for the item 'feeling cold' during cHD (p = .01), PID-PROMs did not differ between modalities, but varied markedly between patients (11/13 items, p < .05). T_b increased in sHD, lvHDF, and hvHDF (+0.30, 0.35, 0.38°C, respectively, all p < .0005), but remained stable in cHD (+0.04°C, p = .43). Thermal perception remained unaltered in sHD and both HDF modalities, but shifted towards cold in cHD (p = .007).

CONCLUSION

(1) PID-PROMs did not differ between modalities, but varied markedly between patients. Hence, PID-PROMs are largely patient-dependent. (2) While T_b increased in sHD, lvHDF and hvHDF, thermal perception did not change. Yet, whereas T_b remained unaltered in cHD, cold perception emerged. Hence, as for bothersome cold sensations, cHD should be avoided in perceptive individuals.

Dietary Intake Correlated to Waist-To-Hip Ratio in Patients on Maintenance Hemodialysis

OBJECTIVE

Individuals with end-stage kidney disease (ESKD) receiving maintenance hemodialysis (MHD) are at risk for protein-energy wasting (PEW). Inadequate dietary intake and altered anthropometrics are two criteria of the PEW diagnosis. This study explored whether individuals with ESKD on MHD meet the National Kidney Foundation Kidney Disease Outcome Quality Initiative (NKF-KDOQI) 2020 guidelines for nutritional adequacy on a dialysis treatment day (DD) and explored the relationship between dietary energy [DEI] and protein [DPI] intake and anthropometrics.

METHODS

This was a secondary analysis of clinical and demographic data for 142 adults from the Rutgers Nutrition and Kidney Disease database. The study assessed the relationships between DEI, DPI, and anthropometrics, including body mass index (BMI), BMI category, waist circumference, and waist-to-hip ratio (WHR) using Pearson's or Spearman's correlation and one-way ANOVA.

RESULTS

The sample had a median age of 55.7 years; 58% were male, 83.8% were Black/African American, with a median dialysis vintage of 42.0 months (e.g., 3.5 years). Seventy-five percent of the data sample were overweight or obese. The WHR was 1.0 ± 0.8 cm for males and 0.9 ± 0.1 for females. DEI and DPI on a DD did not meet the NKF-KDOQI 2020 guidelines. Median DEI was 17.6 ± 8.4 kcal/kg and DPI was 0.7 ± 0.4 g/kg. In the total sample, significant positive correlations were found between DEI (r = 0.74, P = 0.03) and DPI (r = 0.18, P = 0.037) and WHR. In females, a significant positive correlation was identified between DPI and WHR (r = 0.26, P = 0.046).

CONCLUSIONS

These findings suggest that the nutritional intake of individuals with ESKD receiving MHD is inadequate to meet NKF-KDOQI 2020 guidelines on a DD. WHR may be a useful tool to assess alterations in anthropometrics related to DEI or DPI in this population, but more research is warranted.

Psychometric Properties of the Brief Fatigue Inventory in Hemodialysis Patients during a Dialysis Day: A Preliminary Report

The aim of this study was to evaluate the psychometric properties of the Brief Fatigue Inventory (BFI) in hemodialysis patients. During a dialysis day, patients completed both 9-item BFI and 21-item Beck Depression Inventory (BDI)-II questionnaires. The psychometric properties of the BFI were assessed in terms of reliability and validity. The BFI had an overall Cronbach's coefficient alpha of .92. Inter-item correlation coefficients between BFI items ranged from .38 to. 81 (all p < .0001). Exploratory factor analysis revealed bidimensional factor structure of the BFI-fatigue "severity" and fatigue "interference" explaining 11.0% and 62.0% of the total variance in the data set, respectively. In criterion validity analysis, BFI composite score correlated significantly with the total BDI-II score-Pearson correlation coefficient .40 (p < .0001). These preliminary results support the satisfactory psychometric properties of the BFI in assessing fatigue among hemodialysis patients during a dialysis day in a clinic setting.

Development of a patient-reported outcome measure for the assessment of symptom burden in pediatric chronic kidney disease (PRO-Kid)

BACKGROUND

Chronic kidney disease (CKD) and kidney failure in childhood are associated with significant and life-altering morbidities and lower quality of life. Emerging evidence suggests that management should be guided in part by symptom burden; however, there is currently no standardized assessment tool for quantifying symptom burden in this pediatric population. This study aimed to develop and refine a patient-reported symptom assessment tool for children with CKD/kidney failure (PRO-Kid), to evaluate the frequency and impact of symptoms.

METHODS

This was a prospective observational study of children and caregivers of children with CKD/kidney failure at two Canadian pediatric care centers. Building on previously published patient-reported outcome measures (PROs) for the assessment of symptom burden in other populations, we drafted a 13-item questionnaire. Cognitive interviews were performed with children and caregivers of children with CKD/kidney failure to iteratively refine the questionnaire.

RESULTS

Twenty-four participants completed cognitive interviewing (11 children, 13 caregivers). The most common symptoms endorsed were feeling left out, feeling sad/depressed, inability to focus, tiredness, nausea, vomiting, not wanting to eat, and changes in the taste of food. Feeling left out was added to the questionnaire as almost all participants voiced this as a frequent and impactful symptom, resulting in a 14-item questionnaire.

CONCLUSIONS

PRO-Kid is the first pediatric CKD/kidney failure-specific PRO tool to assess symptom burden. Future work should validate this tool in a larger cohort so that it may be used to improve the care of children living with CKD/kidney failure. A higher resolution version of the Graphical abstract is available as Supplementary information.

Impact of Expanded Hemodialysis Using Medium Cut-off Dialyzer on Quality of Life: Application of Dynamic Patient-Reported Outcome Measurement Tool

Rationale & Objective

Current hemodialysis (HD) treatments have limited ability to clear larger-molecular-weight uremic toxins. Retention is associated with increased symptom burden, low health-related quality of life (HRQoL), and high mortality. Improved clearance, using novel medium cut-off dialyzers, termed expanded HD (HDx), may be associated with improved subjective experience. We have previously developed a dynamic patient-reported outcome measure (PROM) instrument to allow iterative recording to better appreciate the overall burden of disease and assess the impact of therapy changes.

Study Design

Single-center interventional pilot study.

Setting & Participants

28 patients established on maintenance HD, London, Ontario, Canada.

Intervention

Initial study consisting of 2-week observation (baseline-conventional high-flux HD) followed by 12 weeks of HDx. HRQoL was assessed using the dynamic PROM instrument thrice weekly (enabled in a dedicated app as the London Evaluation of Illness [LEVIL]). Extension phase; 2-week baseline with 24 weeks of HDx and 8-week washout.

Outcomes

Principal aim was to establish whether HDx therapy was associated with improved HRQoL, evidence of dose-dependant response, and whether effects were durable over time, using LEVIL.

Results

Patients with lower LEVIL scores (<70/100) at baseline showed improvement in overall HRQoL after 8 weeks of therapy with similar carryover effect. General well-being, energy, and sleep quality were improved significantly as a consequence of HDx therapy. There were no detrimental effects of HDx detected in patients with higher baseline HRQoL.

Limitations

Small nonrandomized sample size. The coronavirus disease 2019 pandemic interfered with the extension phase.

Conclusions

Dynamic PROM assessment effectively identified patients with lower HRQoL and higher symptom burden, demonstrating durable time/dose-dependent improvements across a range of symptom domains. The use of this instrument may allow targeted selection of patients most likely to benefit from HDx therapy and assist in monitoring response and defining effect size and treatment duration to allow optimal design of further definitive randomized controlled trials of this newly introduced technology.

How to assess quality of life in persons with chronic kidney disease

PURPOSE OF REVIEW

Chronic kidney disease (CKD) significantly impacts many aspects of life, health, and wellbeing. People with CKD have individual priorities for their care which may differ from those valued by clinicians and policy makers. The patient experience is broadly captured by the concept of quality of life (QoL) which is increasing assessed in research and used to guide clinical and policy decision making. Appropriate selection and application of QoL assessment tools are essential for high-quality research and patient care. This article summarises the current approaches to QoL assessment in CKD and outlines aspirations for future improvement.

RECENT FINDINGS

Commonly used tools for assessment of QoL in CKD include the Short Form-36 and -12 and extended versions adapted for specific use in kidney patients (KD-QoL), and the EQ-5D. However, a wide range of other instruments are also reported, making comparisons between research findings challenging. Few of the tools are adequately validated for use in CKD, and relevance to patient values are unclear. Instruments suitable for use in a routine clinical setting are lacking.

SUMMARY

QoL instruments developed and validated with meaningful CKD stakeholder input are required. The Standardised Outcomes in Nephrology initiative is working to address this need.

Development of a preliminary conceptual model of the patient experience of chronic kidney disease: a targeted literature review and analysis

Background

Patient-reported outcome (PRO) instruments should capture the experiences of disease and treatment that patients consider most important in order to inform patient-centred care and product development. The aim of this study was to develop a preliminary conceptual model of patient experience in chronic kidney disease (CKD) based on a targeted literature review and to characterize existing PRO instruments used in CKD.

Methods

PubMed, EMBASE and Cochrane databases and recent society meetings were searched for publications reporting signs/symptoms and life impacts of CKD. Concepts identified in the literature review were used to develop a preliminary conceptual model of patient experience of CKD, overall, and within patient subpopulations of differing CKD causes, severities and complications. PRO instruments, identified from PRO databases, CKD literature and CKD clinical trials, were assessed for content validity, psychometric strength and coverage of concepts in the literature review.

Results

In total, 100 publications met criteria for analysis; 56 signs/symptoms and 37 life impacts of CKD were identified from these sources. The most frequently mentioned signs/symptoms were pain/discomfort (57% of publications) and tiredness/low energy/lethargy/fatigue (42%); the most commonly reported life impacts were anxiety/depression (49%) and decrements in physical functioning (43%). Signs/symptoms and life impacts varied across the subpopulations and were more frequent at advanced CKD stages. The preliminary conceptual model grouped signs/symptoms into seven domains (pain/discomfort; energy/fatigue; sleep-related; gastrointestinal-related; urinary-related; skin−/hair−/nails-related; and other) and life impacts into six domains (psychological/emotional strain; cognitive impairment; dietary habit disruption; physical function decrements; interference with social relationships; and other). Eleven PRO instruments were considered to be promising for use in CKD; all had limitations.

Conclusions

Although preliminary, the proposed conceptual model highlights key PROs for people with CKD and is intended to spur development of more tailored PRO instruments to assess these concepts.

Using Patient-Reported Measures to Improve Outcomes in Kidney Disease

Patients with CKD and ESRD are vulnerable to increased mortality rates and other poor outcomes. Among those with ESRD, their health-related quality of life (HRQOL) is shown little to no improvement as they undergo treatments such as dialysis and providers concurrently manage other health issues that complicate their already vulnerable state. This review synthesizes evidence demonstrating that a focus on measuring and monitoring patient-reported outcomes (PRO) such as pain and depression can improve HRQOL. Patient-centered care has the potential to create an efficient way for clinicians to address specific challenges facing patients. While there is an emerging literature assessing the use of PROs in kidney research, by examining relevant research in other disciplines it is possible to generate better ways to use PROs in this high-risk population. Electronic health records as well as various other electronic methods of communication between the clinician and patient may serve to accelerate the trajectory toward patient-centered care using PROs.

A Mixed Methods Study of Symptom Experience in Patients With End-Stage Renal Disease

BACKGROUND

Patients with end-stage renal disease receiving dialysis experience a significant symptom burden. Identifying factors associated with this burden may improve symptom management. However, specific evidence about patients' experiences is lacking.

OBJECTIVES

The aim of this study was to explore factors that are associated with patients' symptom experiences.

METHODS

The convergent parallel mixed methods design was used. In the quantitative component, the Dialysis Symptom Index was used to assess the symptom burden of 271 participants to examine its associations with patient characteristics using correlation coefficients and multivariate regression analyses. In the qualitative component, associated factors reported by 10 participants were identified through semistructured interviews using content analysis. Assessments were conducted at enrollment, 6 months, and 12 months. After separate data analyses, findings were integrated using side-by-side comparison and joint display.

RESULTS

Several significant associations were identified between patient characteristics and symptom burden, and the participants described four categories of factors (i.e., treatment related, pathophysiological, situational, dietary) associated with a higher symptom burden during their interviews. Across both components of this study, three factors were consistent (i.e., employment, hyperphosphatemia, anemia). Participants described several factors not reported previously.

DISCUSSION

This study explored subjective and objective factors influencing the symptom experiences of patients with end-stage renal disease using a mixed methods design. These risk factors can be used to identify high-risk patients. Our findings suggest that participants relied on laboratory results and treatments to explain their symptom experiences. These findings suggest that assessment of both subjective and objective factors is needed to explore patients' symptom experiences.

Opioid Management in CKD

Patients with chronic kidney disease (CKD) experience a high pain and symptom burden. Concurrently, opioid prescription and use in patients with CKD continues to increase, leading to concern for opioid-related risks. Nephrologists increasingly face challenging clinical situations requiring further evaluation and treatment of pain, for which opioid use may be indicated. However, nephrologists are not commonly trained in pain management and may find it difficult to compile the necessary information and tools to effectively assess and treat potentially multidimensional pain. In these situations, they may benefit from using an evidence-based stepwise approach proposed in this article. We address current approaches to opioid use for pain management in CKD and offer a stepwise approach to individualized opioid assessment, focusing on kidney-specific concerns. This includes thorough evaluation of the pain experience, opioid use history, and treatment goals. We subsequently discuss considerations when initiating opioid therapy, strategies to reduce opioid-related risks, and recommended best practices for opioid stewardship in CKD. Using this sequential approach to opioid management, nephrologists can thereby gain a broad overview of key patient considerations, the foundation for understanding implications of opioid use, and a patient-tailored plan for opioid therapy.

Novel conservative management of chronic kidney disease via dialysis-free interventions

PURPOSE OF REVIEW

In advanced chronic kidney disease (CKD) patients with progressive uremia, dialysis has traditionally been the dominant treatment paradigm. However, there is increasing interest in conservative and preservative management of kidney function as alternative patient-centered treatment approaches in this population.

RECENT FINDINGS

The primary objectives of conservative nondialytic management include optimization of quality of life and treating symptoms of end-stage renal disease (ESRD). Dietetic-nutritional therapy can be a cornerstone in the conservative management of CKD by reducing glomerular hyperfiltration, uremic toxin generation, metabolic acidosis, and phosphorus burden. Given the high symptom burden of advanced CKD patients, routine symptom assessment using validated tools should be an integral component of their treatment. As dialysis has variable effects in ameliorating symptoms, palliative care may be needed to manage symptoms such as pain, fatigue/lethargy, anorexia, and anxiety/depression. There are also emerging treatments that utilize intestinal (e.g., diarrhea induction, colonic dialysis, oral sorbents, gut microbiota modulation) and dermatologic pathways (e.g., perspiration reduction) to reduce uremic toxin burden.

SUMMARY

As dialysis may not confer better survival nor improved patient-centered outcomes in certain patients, conservative management is a viable treatment option in the advanced CKD population.

KDOQI US Commentary on the 2020 ISPD Practice Recommendations for Prescribing High-Quality Goal-Directed Peritoneal Dialysis

The recently published 2020 International Society for Peritoneal Dialysis (ISPD) practice recommendations regarding prescription of high-quality goal-directed peritoneal dialysis differ fundamentally from previous guidelines that focused on "adequacy" of dialysis. The new ISPD publication emphasizes the need for a person-centered approach with shared decision making between the individual performing peritoneal dialysis and the clinical care team while taking a broader view of the various issues faced by that individual. Cognizant of the lack of strong evidence for the recommendations made, they are labeled as "practice points" rather than being graded numerically. This commentary presents the views of a work group convened by the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDOQI) to assess these recommendations and assist clinical providers in the United States in interpreting and implementing them. This will require changes to the current clinical paradigm, including greater resource allocation to allow for enhanced services that provide a more holistic and person-centered assessment of the quality of dialysis delivered.

Kidney supportive care: an update of the current state of the art of palliative care in CKD patients

Chronic kidney disease (CKD) has become a public health burden worldwide for its increasing incidence and prevalence, high impact on the health related quality of life (HRQoL) and life expectancy, and high personal and social cost. Patients with advanced CKD, in dialysis or not, suffer a burden from symptoms very similar to other chronic diseases and have a life span not superior to many malignancies. Accordingly, in recent years, renal palliative care has been recommended to be integrated in the traditional care delivered to this population. This research provides an updated overview on renal palliative care from the relevant literature.

The Relationship between Dialysis Metrics and Patient-Reported Cognition, Fatigue, and Physical Function

Introduction

The impact of achieving hemodialysis laboratory and hemodynamic quality metrics on patient-reported outcomes (PROs) is unknown.

Objective

To determine if meeting dialysis laboratory quality of care measures is associated with improved PROs.

Methods

In this cross-sectional study, we measured the relationship between dialysis patients' Patient Reported Outcome Measurement Information System (PROMIS) scores and commonly used dialysis quality of care measures.

Results

PROMIS surveys were administered to 92 dialysis patients. The mean ± SD scores demonstrated higher fatigue (55.0 ± 9.8) and lower physical function (37.9 ± 7.9) but similar cognition (50.3 ± 10.9) compared to general population normative scores of 50 ± 10. Dialysis patients meeting Kt/V goals had no better scores than those who did not. Meeting the hemoglobin (Hgb) value of ≥10 g/dL was associated with a lower fatigue score, but no difference in cognitive or physical function scores. Meeting the serum albumin goal of ≥4.0 mg/dL was associated with a higher physical function score but made no difference for cognitive function or fatigue score. As a continuous variable, a higher Hgb was associated with lower reported fatigue (HR -1.74 95%, CI [-3.09, -0.39]), but no other measures were associated with PRO scores when adjusted for demographics and comorbidities.

Conclusions

We found little association between measures currently used to assess the quality of dialysis care and PROs. Encouraging improved utilization of PROs and incorporating PROs into quality measurements might give a more robust assessment of quality of care. Future studies should assess the benefits of this approach.

Distinct Symptom Experience Among Subgroups of Patients With ESRD Receiving Maintenance Dialysis

CONTEXT

Patients with end-stage renal disease receiving dialysis experience multiple concurrent symptoms. A person-centered understanding of patients' symptom experiences may offer insights into individualized management.

OBJECTIVES

We identified subgroups of patients based on their symptom experiences and the characteristics that differentiated among these subgroups. Outcomes associated with these subgroups were evaluated.

METHODS

A total of 354 patients on dialysis were recruited at two regional hospitals in Hong Kong. While the Dialysis Symptom Index was adopted to assess symptoms, the Kidney Disease Quality of Life 36 and Karnofsky Performance Status Scale were used to evaluate the quality of life outcomes. Information on health care utilization and mortality were retrieved from medical records. Subgroups of patients were identified using latent class analysis based on the occurrence ratings. Differences in characteristics and outcomes were determined using Chi-squared test, analysis of variance, and Cox regression analysis.

RESULTS

Three latent classes were identified: low (37.8%), moderate physical-low psychological (29.7%), and moderate physical-high psychological (32.5%). Higher comorbidity burden and lower serum albumin levels differentiated between the low and moderate physical-low psychological classes. The moderate physical-high psychological class had the highest number of symptoms, poorest quality of life outcomes, and more unscheduled clinic visits. A shorter mean survival time (421 vs. 431 days) was also found.

CONCLUSION

Consistent with findings in other chronic conditions, subgroups of patients on dialysis have unique symptom experiences. Therefore, an individualized approach to symptom management is warranted. Our findings offer a phenotypic characterization for research on the underlying mechanisms for these symptom experiences.

Enabling good outcomes in older adults on dialysis: a qualitative study

Background

Older patients on dialysis may not have optimal outcomes, particularly with regards to quality of life. Existing research is focused mainly on survival, with limited information about other outcomes. Such information can help in shared decision-making around dialysis initiation; it can also be used to improve outcomes in patients established on dialysis. We used qualitative research methods to explore patient perspectives regarding their experience and outcomes with dialysis.

Methods

Semi-structured interviews with participants aged ≥70, receiving dialysis at a regional Australian hospital, were recorded and transcribed. From participants’ responses, we identified descriptive themes using a phenomenological approach, with verification by two researchers. Factors affecting outcomes were derived reflexively from these themes.

Results

Seventeen interviews were analysed prior to saturation of themes. Participants (12 on haemodialysis, 5 on peritoneal dialysis) had spent an average of 4.3 years on dialysis. There were 11 males and 6 females, with mean age 76.2 years (range 70 to 83). Experiences of dialysis were described across four domains - the self, the body, effects on daily life and the influences of others; yielding themes of (i) responses to loss (of time, autonomy, previous life), (ii) responses to uncertainty (variable symptoms; unpredictable future; dependence on others), (iii) acceptance / adaptation (to life on dialysis; to ageing) and (iv) the role of relationships / support (family, friends and clinicians).

Conclusions

Older patients experience the effects of dialysis across multiple domains in their lives. They endure feelings of loss and persistent uncertainty, but may also adapt successfully to their new circumstances, aided by the support they receive from family, health professionals and institutions. From these insights, we have suggested practical measures to improve outcomes in older patients.

Stability and Impact of Symptom Clusters in Patients With End-Stage Renal Disease Undergoing Dialysis

CONTEXT

Patients with end-stage renal disease undergoing dialysis experience multiple concurrent symptoms. These symptoms cluster together and have negative impacts on patient outcomes. However, information on changes in symptom clusters over time is limited.

OBJECTIVES

This longitudinal study examined the stability of symptom clusters and their impacts on health-related quality of life and functional status over a period of one year.

METHODS

Eligibility criteria were patients diagnosed with end-stage renal disease; had received dialysis consecutively for at least three months; and had given written informed consent. Dialysis Symptom Index, Kidney Disease Quality of Life 36, and Karnofsky Performance Status Scale were used to evaluate the impacts of symptom clusters and outcomes. Exploratory factor analyses and multiple regression analyses were used to determine symptom clusters and their associations with patient outcomes.

RESULTS

Among the 354 recruited patients, 271 completed the 12-month assessment. Four symptom clusters were identified across the three assessments, namely, uremic, gastrointestinal, skin, and emotional. Within each cluster, the specific symptoms were varied. The uremic symptom cluster accounted for the largest amount of variability. Across the three assessments, a higher uremic cluster factor score was associated with poorer physical well-being, whereas a higher emotional cluster factor score was consistently associated with poorer mental well-being.

CONCLUSION

Symptoms in patients on dialysis clustered in relatively stable patterns. The four symptom clusters identified had consistent negative effects on various aspects of patients' well-being. Our findings suggest the need for ongoing symptom assessment and early recognition of symptoms that may contribute to adverse patient outcomes.

Perspectives on symptom experiences and symptom reporting among individuals on hemodialysis

Background

Individuals on hemodialysis bear substantial symptom burdens, but providers often underappreciate patient symptoms. In general, standardized, patient-reported symptom data are not captured during routine dialysis care. We undertook this study to better understand patient experiences with symptoms and symptom reporting. In exploratory interviews, we sought to describe hemodialysis nurse and patient care technician perspectives on symptoms and symptom reporting.

Methods

We conducted semi-structured interviews with 42 US hemodialysis patients and 13 hemodialysis clinic personnel. Interviews were conducted between February and October 2017 and were analyzed using thematic analysis.

Results

Seven themes were identified in patient interviews: (i) symptoms engendering symptoms, (ii) resignation that life is dependent on a machine, (iii) experiencing the life intrusiveness of dialysis, (iv) developing adaptive coping strategies, (v) creating a personal symptom narrative, (vi) negotiating loss of control and (vii) encountering the limits of the dialysis delivery system. Overall, patient symptom experiences and perceptions appeared to influence symptom-reporting tendencies, leading some patients to communicate proactively about symptoms, but others to endure silently all but the most severe symptoms. Three themes were identified in exploratory clinic personnel interviews: (i) searching for symptom explanations, (ii) facing the limits of their roles and (iii) encountering the limits of the dialysis delivery system. In contrast to patients, clinic personnel generally believed that most patients were inclined to spontaneously report their symptoms to providers.

Conclusions

Interviews with patients and dialysis clinic personnel suggest that symptom reporting is highly variable and likely influenced by many personal, treatment and environmental factors.

Reasons for Underreporting of Uremic Pruritus in People With Chronic Kidney Disease: A Qualitative Study

CONTEXT

Uremic pruritus, or itch, is common in people with chronic kidney disease (CKD) and has a negative impact on their lives and well-being. However, for reasons currently unknown, itch often remains unreported and therefore untreated.

OBJECTIVES

To explore reasons for underreporting of itch to provide pointers for improving itch reporting and management in people with CKD.

METHODS

We interviewed adult patients with CKD who self-reported experiencing itching in the last three years (n = 25), nephrologists (n = 10), and nurses (n = 12) from three kidney services in the U.K. Topic guides were informed by previous studies and a theoretical model of self-regulation. We conducted a thematic analysis of verbatim transcripts using framework analysis.

RESULTS

We identified the following three main themes reflecting factors that may influence whether itch is reported: knowledge on causes and treatment of itch (lack of awareness of the relationship between itch and CKD, and lack of knowledge of treatment options); attitudes toward importance of itch as a health issue (patients' and clinicians' attitudes); and prompts for itch assessment during consultations (routine practice, itch as a marker, and itch severity).

CONCLUSION

Underreporting of itch is related to patients being unaware of its causes, accepting it as something to live with, prioritizing other health issues, and the length and timing of consultations. Health care professionals' assessment and management of itch vary widely and are not necessarily evidence-based. Better patient information, development of clinical practice guidelines, and incorporation of routine symptom assessments into care may improve itch reporting and management in people with CKD.

Patient-reported outcome measures: selection of a valid questionnaire for routine symptom assessment in patients with advanced chronic kidney disease - a four-phase mixed methods study

Background

Patient-reported outcome measures (PROMs) are becoming increasingly important in healthcare. In nephrology, there is no agreement on which chronic kidney disease (CKD) symptom questionnaire to use. Therefore, the aim of this study is to select a valid symptom questionnaire for routine assessment in patients with advanced CKD.

Methods

A four-phase mixed methods approach, using qualitative and quantitative research methods, was applied. First, a systematic literature search was conducted to retrieve existing symptom questionnaires. Second, a symptom list was created including all symptoms in existing questionnaires and symptoms mentioned in interviews with patients with CKD, from which symptom clusters were identified. Next, questionnaires were selected based on predefined criteria regarding content validity. Last, two online feedback panels of patients with CKD (n = 151) and experts (n = 6) reviewed the most promising questionnaires.

Results

The literature search identified 121 questionnaires, of which 28 were potentially suitable for symptom assessment in patients with advanced CKD. 101 unique symptoms and 10 symptom clusters were distinguished. Based on predefined criteria, the Dialysis Symptom Index (DSI) and Palliative Care Outcome Scale-Renal Version (IPOS-Renal) were selected and reviewed by feedback panels. Patients needed 5.4 and 7.5 min to complete the DSI and IPOS-Renal, respectively (p < 0.001). Patients experienced the DSI as more specific, complete and straightforward compared to the IPOS-Renal.

Conclusions

The DSI was found to be valid and reliable, the most relevant, complete, and comprehensible symptom questionnaire available for routine assessment in patients with advanced CKD. Routine PROMs collection could be of great value to healthcare, both at individual patient and national level. Feedback on scores and involvement of healthcare providers may promote adaptation and implementation in healthcare.

Fatigue in Individuals with End Stage Renal Disease

Fatigue is a subjective overwhelming feeling of tiredness at rest, exhaustion with activity, lack of energy that impedes daily tasks, lack of endurance, or a loss of vigor. Individuals with end stage renal disease (ESRD) experience a high rate and severity of fatigue. Symptom management of fatigue in this population is critical, since fatigue has been linked with lower quality of life and higher mortality rates. In this article, we present a definition and overview of fatigue, a review of factors contributing to fatigue, and ways to manage fatigue in individuals with ESRD.

Patient-reported outcome measures and their utility in the management of patients with advanced chronic kidney disease

Symptom and quality of life (QOL) measures in patients with advanced chronic kidney disease are recognized indicators of patient-centred care and represent important research, quality and clinical measures. This study examined relationships between symptom burden, QOL and functional status and associations of symptoms and mortality risk. A multisite longitudinal cohort analysis was undertaken in chronic kidney disease stage 4/5 (no dialysis) and dialysis patients. Patients completed symptom and QOL measures (Palliative Care Outcome Symptom Score renal), World Health Organisation QOL Brief Version) and Karnofsky Performance scale. Clinical and demographic data were recorded.

The Use of Patient-Reported Outcomes in Patients Treated With Maintenance Hemodialysis: A Perspective

There is increasing interest in the integration of patient-reported outcomes (PROs) into health care research and clinical practice for the benefit of patients with end-stage kidney disease receiving hemodialysis. In a research setting, PROs can be used as a patient-centered primary or secondary outcome in clinical studies. In routine care, PRO data may be used to support service delivery through benchmarking and audit or inform and enhance the care of the individual patient by improving patient-clinician communication. Despite evidence demonstrating the potential benefits of PROs and prioritization of these outcomes by patients, their use in kidney disease remains limited. Although there are significant methodological and operational challenges for the widespread integration of PROs, there is now consensus that this area should be at the forefront of clinical research and implementation science. We discuss the current use of PROs for patients with end-stage kidney disease receiving hemodialysis and identify a roadmap for increasing the evidence base and introducing PROs into mainstream clinical practice.

Changes in Symptom Burden in Dialysis Patients Assessed Using a Symptom-Reporting Questionnaire in Clinic

Introduction:

To determine the prevalence, severity, and change in symptoms experienced by dialysis patients following the introduction of use of a symptom-reporting questionnaire in nephrology clinic.

Methods:

This is an observational study of 160 prevalent dialysis patients. Palliative care Outcome Scale symptom (POS-renal) questionnaires modified for patients with end-stage kidney disease were completed at baseline and follow-up (median 3 months), with results available to nephrologists at clinic appointments.

Findings:

The baseline prevalence of individual symptoms ranged from 15% to 66%. The most common symptoms were lack of energy (66%) and poor mobility (58%). The median number of symptoms was 7/17 (interquartile range [IQR]: 4-10). Forty-nine percent of patients rated at least 1 symptom as severe or overwhelming. At follow-up, the median number of symptoms experienced was unchanged at 7/17 (IQR: 3-10). However, there was considerable flux in symptom severity. On average, individual symptoms that were present at baseline improved in 56% of patients and worsened in 18%; only 26% had stable symptom severity. Individual symptoms newly occurred in 8% to 20% of patients between time points, with 77% of patients experiencing at least 1 new symptom. The percent of patients rating at least 1 symptom as severe or overwhelming was reduced from 49% to 39% ( P = .040).

Conclusions:

Use of the POS-renal questionnaire identified a high symptom burden. The presence and severity of symptoms changed dramatically over a short follow-up period, highlighting the need for regular surveillance of symptoms in the dialysis population. Routine use of a symptom questionnaire in clinic may be useful for the identification and management of symptoms in dialysis patients.

Health-related quality of life in peritoneal dialysis patients: A narrative review

Health-related quality of life (HRQOL) is an important aspect of patients´ health that should be an integral part of the evaluation of patient-centered outcomes, not least because HRQOL associates with patients´ morbidity and mortality. This applies also to chronic kidney disease patients, including those dependent on renal replacement therapies, the type of which may influence patients´ perception of HRQOL. Several studies have addressed HRQOL in chronic kidney disease patients undergoing renal replacement therapies, especially transplanted patients and hemodialysis patients, while publications concerning peritoneal dialysis (PD) patients are scarcer. This review describes some of the methods used to assess HRQOL, factors influencing HRQOL in PD patients, HRQOL in PD vs hemodialysis, and the relation between HRQOL and patient outcomes. We conclude that assessment of HRQOL-often neglected at present-should be included as a standard measure of patient-centered outcomes and when monitoring the quality and effectiveness of renal care including PD treatment.

Development of an International Standard Set of Value-Based Outcome Measures for Patients With Chronic Kidney Disease: A Report of the International Consortium for Health Outcomes Measurement (ICHOM) CKD Working Group

Value-based health care is increasingly promoted as a strategy for improving care quality by benchmarking outcomes that matter to patients relative to the cost of obtaining those outcomes. To support the shift toward value-based health care in chronic kidney disease (CKD), the International Consortium for Health Outcomes Measurement (ICHOM) assembled an international working group of health professionals and patient representatives to develop a standardized minimum set of patient-centered outcomes targeted for clinical use. The considered outcomes and patient-reported outcome measures were generated from systematic literature reviews. Feedback was sought from patients and health professionals. Patients with very high-risk CKD (stages G3a/A3 and G3b/A2-G5, including dialysis, kidney transplantation, and conservative care) were selected as the target population. Using an online modified Delphi process, outcomes important to all patients were selected, such as survival and hospitalization, and to treatment-specific subgroups, such as vascular access survival and kidney allograft survival. Patient-reported outcome measures were included to capture domains of health-related quality of life, which were rated as the most important outcomes by patients. Demographic and clinical variables were identified to be used as case-mix adjusters. Use of these consensus recommendations could enable institutions to monitor, compare, and improve the quality of their CKD care.

Chronic kidney disease predicts a lower probability of improvement in patient-reported experience measures among patients with fractures: a prospective multicenter cohort study

Patient-reported experience measures (PREMs) are integral component of care for fracture patients. Using a multicenter cohort, we showed that the presence of chronic kidney disease (CKD) attenuated the probability of PREM improvement in fracture patients.

INTRODUCTION

Assessing PREM can assist physicians in improving patients' experiences. Patients with CKD are at an increased risk of exhibiting poor PREM and developing fractures. We aimed to assess whether CKD influences the probability of PREM improvement during follow-up among patients with fractures.

METHODS

We prospectively enrolled patients with hip or vertebral fractures from different institutes into a fracture liaison service program. After registering clinical histories, they received a baseline PREM assessment based on EuroQol group-5 dimension content, including self-care, daily activity, and pain severity using a 5-point Likert scale. A follow-up PREM assessment was arranged 4 months later, and we evaluated whether baseline CKD was predictive of PREM improvement.

RESULTS

Among 593 fracture patients (18% with CKD), 37.3% and 62.7% presented with hip and vertebral fractures, respectively. Self-care, daily activity, and pain severity improved after follow-up in 32%, 27%, and 43% participants; those with CKD exhibited worse self-care ability and daily activity than those without. Multivariate logistic regression analyses showed that baseline CKD was significantly associated with lower possibility of improvement in daily activity (odds ratio [OR] 0.58, p = 0.049) and pain severity (OR 0.52, p = 0.01), and an insignificant change in the possibility of improvement in self-care ability (OR 0.61, p = 0.09).

CONCLUSIONS

The presence of CKD predicts a significantly lower probability of PREM improvement among fracture patients. An early emphasis on renal function during fracture care should be considered.

Data and knowledge standards for learning health: A population management example using chronic kidney disease

The widespread creation of learning health care systems (LHSs) will depend upon the use of standards for data and knowledge representation. Standards can facilitate the reuse of approaches for the identification of patient cohorts and the implementation of interventions. Standards also support rapid evaluation and dissemination across organizations. Building upon widely-used models for process improvement, we identify specific LHS activities that will require data and knowledge standards. Using chronic kidney disease (CKD) as an example, we highlight the specific data and knowledge requirements for a disease-specific LHS cycle, and subsequently identify areas where standards specifications, clarification, and tools are needed. The current data standards for CKD population management recommendations were found to be partially ambiguous, leading to barriers in phenotyping, risk identification, patient-centered clinical decision support, patient education needs, and care planning. Robust tools are needed to effectively identify patient health care needs and preferences and to measure outcomes that accurately depict the multiple facets of CKD. This example presents an approach for defining the specific data and knowledge representation standards required to implement condition-specific population health management programs. These standards specifications can be promoted by disease advocacy and professional societies to enable the widespread design, implementation, and evaluation of evidence-based health interventions, and the subsequent dissemination of experience in different settings and populations.

Symptom burden amongst patients suffering from end-stage renal disease and receiving dialysis: A literature review

Patients suffering from end-stage renal disease and receiving dialysis experience a high symptom burden, which leads to an impaired quality of life and is associated with an increased risk of future hospitalisation and mortality. However, the symptom burden amongst patients undergoing dialysis was often underrecognised by clinical staff. In this paper, related works on symptom burden amongst patients with end-stage renal disease receiving dialysis, its concepts, assessment tools, status, and influencing factors were reviewed to draw clinical staff's attention for the relief of symptom burden amongst these patients and provide a reference for further research.

Development and content validity of a hemodialysis symptom patient-reported outcome measure

PURPOSE

To describe the process and preliminary qualitative development of a new symptom-based patient-reported outcome measure (PROM) intended to assess hemodialysis treatment-related physical symptoms.

METHODS

Experienced interviewers conducted concept elicitation and cognitive debriefing interviews with individuals receiving in-center hemodialysis in the United States. Concept elicitation interviews involved eliciting spontaneous reports of symptom experiences and probing to further explore and confirm concepts. We used patient-reported concepts to generate a preliminary symptom PROM. We conducted 3 rounds of cognitive debriefing interviews to evaluate symptom relevance, item interpretability, and draft item structure. We iteratively refined the measure based on cognitive interview findings.

RESULTS

Forty-two adults receiving in-center hemodialysis participated in the concept elicitation interviews. A total of 12 symptoms were reported by > 10% of interviewees. We developed a 13-item initial draft instrument for testing in 3 rounds of cognitive interviews with an additional 52 hemodialysis patients. Participant responses and feedback during cognitive interviews led to changes in symptom descriptions, division of the single item "nausea/vomiting" into 2 distinct items, removal of daily activity interference items, addition of instructions, and clarification about the recall period, among other changes.

CONCLUSIONS

Symptom Monitoring on Renal Replacement Therapy-Hemodialysis (SMaRRT-HD™) is a 14-item PROM intended for use in hemodialysis patents. SMaRRT-HD™ uses a single treatment recall period and a 5-point Likert scale to assess symptom severity. Qualitative interview data provide evidence of its content validity. SMaRRT-HD™ is undergoing additional testing to assess measurement properties and inform measure scoring.

Validation of the IPOS-Renal Symptom Survey in Advanced Kidney Disease: A Cross-sectional Study

CONTEXT

The significant symptom burden in advanced renal disease is often poorly recognized by clinicians. Recently, the Integrated Palliative Outcome Score (IPOS)-renal survey was developed from pre-existing tools to capture these symptoms and other common concerns.

OBJECTIVES

We studied the validity and reliability of the IPOS-renal survey (patient and staff versions) in an Australian population.

METHODS

Adult patients with advanced renal disease and nurses caring for them were participated. We initially administered the IPOS-renal survey simultaneously with other validated surveys and then retested the IPOS-renal after seven to 14 days. We tested the construct validity of 1) IPOS-renal patient version in relation to the Edmonton Symptom Assessment Survey-revised and the Kidney Diseases quality of life-short form version 1.3 questionnaire and 2) IPOS-renal staff version in relation to the Support Team Assessment Schedule survey.

RESULTS

Eighty-one patients (65 hemodialysis, 10 peritoneal dialysis, and six on supportive care; average age 64.9 years) and 53 nurses (average renal nursing experience 10.9 years) were participated. Intraclass coefficients for test-retest reliability were >0.7 for most queries; Cronbach's alphas for internal consistency were 0.84 (patient version) and 0.91 (staff version). In tests of construct validity, Spearman's coefficient of correlation between surveys and their comparators for similar questions was significant, at 0.61 to 0.77 (patients) and 0.24 to 0.76 (staff). As expected, symptom scores and total symptom burden were negatively correlated with summary scores of quality of life.

CONCLUSION

The IPOS-renal surveys, patient and staff versions, have good test-retest reliability, internal consistency, and construct validity in patients with advanced kidney disease and their nurses. We recommend their use in symptom assessment.

Quality of life, clinical outcome, personality and coping in chronic hemodialysis patients

RATIONAL

Our aim was to investigate the quality of life (QoL) in 103 patients undergoing chronic hemodialysis (HD) in an integrated assessment of clinical, personological, and adaptation parameters, also in a non-urban context.

OBJECTIVES

We collected data from all chronic HD patients attending four HD units. Clinical status was assessed by Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines and by Age-adjusted Charlson Comorbidity Index (ACCI). Patients completed the following questionnaires: Kidney Disease Quality of Life Short Form (KDQOL-SF), Pittsburgh Sleep Quality Index (PSQI). Personality profile and coping style were assessed by Temperament and Character Inventory (TCI) revised and Coping Inventory for Stressful Situation (CISS). Data were analyzed by conventional descriptive statistics. Multiple forward stepwise linear regression analyses were performed.

MAIN FINDINGS

Variables significantly associated with physical and mental components of KDQOL-SF were: intact parathyroid hormone (iPTH) (p = .004; p = .0015), typology of cohabitant (family member or not) (p = .022; p = .007), years of dialysis (p = .022; p = .048). Variables associated with mental component of KDQOL-SF were: PSQI (p = .000), task-coping (p = .000), avoidance-coping (p = .003), work status (p = .021). Principle conclusions: Our results suggest the importance of an integrated and multidirectional management of patients chronically undergoing HD and living in a non-urban context.

Why does quality of life remain an under-investigated issue in chronic kidney disease and why is it rarely set as an outcome measure in trials in this population?

The growing importance of quality of life (QoL) measures in health care is reflected by the increased volume and rigor of published research on this topic. The ability to measure and assess patients' experience of symptoms and functions has transformed the development of disease treatments and interventions. However, QoL remains an under-investigated issue in chronic kidney disease (CKD) and is seldom set as an outcome measure in trials in this population. In this article, we present various challenges in using patient-reported outcome (PRO) end points in CKD trials. We outline the need for additional research to examine more closely patient experiences with specific kidney disease symptoms and conditions, as well as caregiver perspectives of patients' symptom burden and end-of-life experiences. These efforts will better guide the development or enhancement of PRO instruments that can be used in clinical trials to more effectively assess treatment benefit, and improve therapy and care. Better understanding of health-related QoL issues would enable providers to deliver more patient-centered care and improve the overall well-being of patients. Even small improvements in QoL could have a large impact on the population's overall health and disease burden.

Physical frailty and functional status in patients with advanced kidney disease: a protocol for a systematic review

BACKGROUND

Predicting outcomes in those with chronic kidney disease or following transplantation is challenging, and current models lack detailed patient-level information. Frailty and poor functional status are risk factors for adverse patient outcomes that may be useful additions to prognostic tools in patients with chronic kidney disease. The purpose of this systematic review is to examine whether frailty or functional status are associated with increased risk of mortality or adverse clinical outcomes in patients with advanced kidney disease.

METHODS/DESIGN

We will conduct a systematic review to identify and evaluate studies linking frailty and functional status with patient outcomes in populations with advanced kidney disease. We will search MEDLINE, Embase, and the Cochrane Central Register for Controlled Trials. Two reviewers will conduct all screening and data extraction independently. A modified version of the Quality In Prognosis Studies tool will be used to evaluate the quality of the studies. If meta-analysis of outcome data is possible, a random effects model will be used.

DISCUSSION

The results of this review will inform the development, selection, and validation of appropriate metrics needed to improve prognostication in patients with chronic kidney disease.

Symptoms and their recognition in adult haemodialysis patients: Interactions with quality of life

AIM

We investigated the symptom burden in adults on haemodialysis, the recognition of symptoms by nurses and nephrologists, and the relationship between symptoms and quality of life.

METHODS

In this cross-sectional observational study, symptoms and quality of life in haemodialysis patients were determined using validated surveys. Nurses and nephrologists independently estimated their patients' symptoms, and these estimates were compared with patient responses (sensitivity; kappa values for interrater agreement). Associations between symptoms and quality of life were assessed using multi-level regression.

RESULTS

Forty-three patients, 18 nurses and 3 nephrologists participated. The commonest symptoms (95%CI) reported by patients were weakness, 69% (53 to 82); poor mobility, 44% (29 to 60); and drowsiness, 44% (29 to 60). Sensitivity less than 50% was seen towards 11 of 17 symptoms in nurse ratings compared with 15 of 17 in nephrologist ratings. Agreement with patient symptom ratings was mostly 'fair' (0.21-0.4), with nurses' scores showing greater agreement than nephrologists'. Physical, mental and kidney disease component summary scores of quality of life were negatively associated with total symptom score and the number of 'major' symptoms (r² values 0.3-0.36); while with multivariate regression, 50% to 60% of the variance in these scores was accounted for by parsimonious models containing symptoms such as pain and poor mobility.

CONCLUSION

Symptom burden worsened quality of life scores in haemodialysis patients. Clinician recognition of symptom burden was inaccurate, although nurses were more accurate than nephrologists. Using patient-completed surveys or including dialysis nurse feedback in routine outpatient settings may help improve symptom recognition by nephrologists.

Nephrologists' Perspectives on Defining and Applying Patient-Centered Outcomes in Hemodialysis

BACKGROUND AND OBJECTIVES

Patient centeredness is widely advocated as a cornerstone of health care, but it is yet to be fully realized, including in nephrology. Our study aims to describe nephrologists' perspectives on defining and implementing patient-centered outcomes in hemodialysis.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Face-to-face, semistructured interviews were conducted with 58 nephrologists from 27 dialysis units across nine countries, including the United States, the United Kingdom, Australia, Austria, Belgium, Canada, Germany, Singapore, and New Zealand. Transcripts were thematically analyzed.

RESULTS

We identified five themes on defining and implementing patient-centered outcomes in hemodialysis: explicitly prioritized by patients (articulated preferences and goals, ascertaining treatment burden, defining hemodialysis success, distinguishing a physician-patient dichotomy, and supporting shared decision making), optimizing wellbeing (respecting patient choice, focusing on symptomology, perceptible and tangible, and judging relevance and consequence), comprehending extensive heterogeneity of clinical and quality of life outcomes (distilling diverse priorities, highly individualized, attempting to specify outcomes, and broadening context), clinically hamstrung (professional deficiency, uncertainty and complexity in measurement, beyond medical purview, specificity of care, mechanistic mindset [focused on biochemical targets and comorbidities], avoiding alarm, and paradoxical dilemma), and undermined by system pressures (adhering to overarching policies, misalignment with mandates, and resource constraints).

CONCLUSIONS

Improving patient-centered outcomes is regarded by nephrologists to encompass strategies that address patient goals and improve wellbeing and treatment burden in patients on hemodialysis. However, efforts are hampered by ambiguities about how to prioritize, measure, and manage the plethora of critical comorbidities and broader quality of life outcomes in a care setting that is technically demanding and driven by biochemical targets. Identifying critical patient-important outcomes and mechanisms for integrating them into practice may help to deliver patient-centered care in hemodialysis and other chronic disease settings.

The Edmonton Symptom Assessment System 25 Years Later: Past, Present, and Future Developments

CONTEXT

Routine symptom assessment represents the cornerstone of symptom management. Edmonton Symptom Assessment System (ESAS) is one of the first quantitative symptom assessment batteries that allows for simple and rapid documentation of multiple patient-reported symptoms at the same time.

OBJECTIVES

To discuss the historical development of ESAS, its current uses in different settings, and future developments.

METHODS

Narrative review.

RESULTS

Since its development in 1991, ESAS has been psychometrically validated and translated into over 20 languages. We will discuss the variations, advantages, and limitations with ESAS. From the clinical perspective, ESAS is now commonly used for symptom screening and longitudinal monitoring in patients seen by palliative care, oncology, nephrology, and other disciplines in both inpatient and outpatient settings. From the research perspective, ESAS has offered important insights into the nature of symptom trajectory, symptom clusters, and symptom modulators. Furthermore, multiple clinical studies have incorporated ESAS as a study outcome and documented the impact of various interventions on symptom burden. On the horizon, multiple groups are actively investigating further refinements to ESAS, such as incorporating it in electronic health records, using ESAS as a trigger for palliative care referral, and coupling ESAS with personalized symptom goals to optimize symptom response assessment.

CONCLUSION

ESAS has evolved over the past 25 years to become an important symptom assessment instrument in both clinical practice and research. Future efforts are needed to standardize this tool and explore its full potential to support symptom management.

Symptoms among patients receiving in-center hemodialysis: A qualitative study

INTRODUCTION

Assessment of dialysis-related symptoms is not currently a requirement for hemodialysis (HD) providers in the United States. The purpose of this study was to describe patients' perspectives on symptoms associated with end-stage chronic kidney disease treated with thrice-weekly, in-center HD.

METHODS

We performed a qualitative study using interpretive description. Interview questions were based on a KDIGO (Kidney Disease Improving Global Outcomes) controversies conference and a literature review. Semi-structured interviews were analyzed for characterizations of symptoms.

FINDINGS

Fifty participants (48% female; 42% Hispanic; 30% American Indian; 14% Black; 12% non-Hispanic White) were recruited from six outpatient dialysis centers (four urban, two rural) in the southwestern United States. Median HD duration was 4 years. Of 13 symptoms assessed, nearly all participants reported difficulties with muscle cramping, fatigue, or both. Negotiating fluid removal with dialysis personnel helped to manage cramping. Some participants tried to adjust dialysis days and shift to mitigate fatigue. Most participants reported having experienced depression early in the course of dialysis; for some, it was a persistent or recurrent problem. Relatively few participants reported using antidepressants or counseling to cope with depression. Itching was highly distressing for those who experienced it frequently. Topical treatments, antihistamines, dietary modifications, and phosphate binders were identified as potentially helpful by some participants.

DISCUSSION

The major symptoms attributed to HD treatment by participants were cramping, fatigue, depression, and itching. Greater attention by health care providers to the most common and bothersome symptoms could positively impact daily life for HD patients.

Collection of daily patient reported outcomes is feasible and demonstrates differential patient experience in chronic kidney disease

INTRODUCTION

Patient reported outcomes (PROs) are a critical metric documenting the impact of disease and treatment from the patient's perspective. A variety of generic and disease specific PRO measures (PROMs) are used in chronic kidney disease (CKD) but studies are primarily cross-sectional. None of the available PROMs are designed for frequent iterative application.

METHODS

An online PROM for daily use in dialysis and CKD 4/5 patients was developed. The custom website utilised visual analogue scales to capture 6 PROs (general well being (GWB), pain, sleep, breathing, energy, and appetite). Outcomes of interest were uptake, response rates, intermodality variation, and change in PRO corresponding to predefined events.

FINDINGS

Forty-three patients submitted at least once and 34 submitted beyond 30 days. Median follow-up was 247 days, 64% male, age 62 ± 12 years. In individuals submitting for >30 days, dialysis patients had significantly worse median scores compared to CKD for sleep (47[32-80], 97[76-99], P = 0.003), appetite (66[50-96], 97[88-100], P = 0.008), energy (47[40-89], 84[67-96], P = 0.031), and GWB (63[49-94], 93[71-98], P = 0.026). Patients demonstrated a variety of stable bandwidths of response, deviations from this were associated with specific events e.g., acute admission, vascular procedures, disturbed fluid status, and dialysis start.

DISCUSSION

We successfully introduced an online, patient acceptable, iterative PROM that discriminates symptom burden, cross-sectionally, and longitudinally. Further work will prospectively examine the predictive power of changes in PRO and more rigorously investigate the potential use of these methods to optimise patient care.
