Patient-Reported Outcome Measures for Fatigue in Patients on Hemodialysis: A Systematic Review

Occupational Priorities of People on Hemodialysis Who Participated in Energy Management Education

Background. People with kidney failure who undergo hemodialysis treatment and experience chronic fatigue identify negative effects on occupational performance and participation as a key aspect of their illness experience. Purpose. To describe the occupational performance and participation problems of people treated with hemodialysis who live with debilitating fatigue. Method. Fifteen participants, who were randomized to participate in an energy management intervention as part of a randomized controlled trial, completed two occupation-based assessments at baseline and chose three priority occupational performance or participation problems to address as goals during the intervention. Results were analyzed using descriptive statistics (counts and percentages). Findings. Fifteen participants (mean age 60, 53% male) completed the occupation-based assessments. Participants stated that they wanted or needed more energy for a median of 22 of 55 occupations. Going out for food/drinks (n = 11), going to a movie/concert/performance (n = 10), and food preparation/clean-up (n = 10) were the top occupations for which participants required more energy. Prioritized occupational performance and participation problems most often fell within the household management (14 goals), self-care (6 goals), and hobbies (5 goals) domains. Conclusion. Occupational performance and participation problems are extensive among people treated with hemodialysis who live with debilitating fatigue. There is a clear need for occupation-based interventions that optimize occupational performance and participation in this population.

Haemodialysis distress thermometer scale: Turkish validity and reliability study

PURPOSE

This study aimed to translate and adapt the "Haemodialysis Distress Thermometer Scale" (HDDT) into Turkish and assess its validity and reliability.

METHODS

This study collected data from 223 haemodialysis patients across three public hospitals in Kütahya province, Türkiye, over a seven-week period.

RESULTS

In this study, the content validity index of the scale was determined to be 0.96. Validity analysis results indicated that factor loadings ranged between 0.45 and 0.82, the total variance explained was 59.25%, and the fit indices were X2/df = 1.149 and RMSEA = 0.026. Reliability analysis showed that the total Cronbach's α coefficient was 0.80, with item-total correlation coefficients ranging from 0.37 to 0.73. The cut-off score for the HDDT barometer was identified as 6.5. The final structure of the HDDT scale comprised 40 items, four factors, and an 11-point barometer, consistent with the original scale.

CONCLUSION

The Turkish version of the HDDT is a valid and reliable instrument for assessing distress in patients undergoing haemodialysis treatment. It may serve as a valuable tool for nurses in identifying and addressing patient distress during haemodialysis care.

Brain connectome gradient dysfunction in patients with end-stage renal disease and its association with clinical phenotype and cognitive deficits

A cortical hierarchical architecture is vital for encoding and integrating sensorimotor-to-cognitive information. However, whether this gradient structure is disrupted in end-stage renal disease (ESRD) patients and how this disruption provides valuable information for potential clinical symptoms remain unknown. We prospectively enrolled 77 ESRD patients and 48 healthy controls. Using resting-state functional magnetic resonance imaging, we studied ESRD-related hierarchical alterations. The Neurosynth platform and machine-learning models with 10-fold cross-validation were applied. ESRD patients had abnormal gradient metrics in core regions of the default mode network, sensorimotor network, and frontoparietal network. These changes correlated with creatinine, depression, and cognitive functions. A logistic regression classifier achieved a maximum performance of 84.8% accuracy and 0.901 area under the ROC curve (AUC). Our results highlight hierarchical imbalances in ESRD patients that correlate with diverse cognitive deficits, which may be used as potential neuroimaging markers for clinical symptoms.

Analysis of Sleep Quality Categories and Associated Factors in Patients on Hemodialysis

INTRODUCTION

Latent profile analysis is a statistical method for identifying potential groups or profiles and categorizing individuals accordingly. In psychology and social sciences, it is frequently employed to explore the latent group structure in data, aiding researchers in comprehending disparities and similarities among different groups. This study utilized latent profile analysis to explore the potential categories of sleep quality in patients on hemodialysis and analyze the factors associated with each category.

METHODS

Convenience sampling was used to select 268 patients who received maintenance hemodialysis treatment at China-Japan Friendship Hospital from July 2023 to June 2024. This study was a cross-sectional survey, and data were collected using a general information survey, the Pittsburgh Sleep Quality Index, Frailty Screening Scale, and Fatigue Scale-14. Different sleep types were identified in patients on hemodialysis using latent profile analysis, and the factors affecting sleep quality in each type were analyzed.

FINDINGS

The study included 154 males and 114 females, with a mean age of 61.07 ± 13.72 years and a median dialysis duration of 4.00 (2.00, 9.00) years. Latent profile analysis identified four sleep quality categories among patients on hemodialysis: good sleep quality (35.30%), insufficient sleep time with high medication use (13.80%), good sleep time with high medication use (4.50%), and insufficient sleep time with low medication use (46.40%). Sex, age, employment status, ultrafiltration volume, frailty screening scale, and fatigue rate-14 were compared among the different categories, revealing significant differences (p < 0.05).

DISCUSSION

Latent profile analysis identified four sleep quality categories among patients undergoing hemodialysis, with factors, such as age, dialysis duration, and the presence of frailty influencing sleep quality differently. Future efforts should focus on this population by providing targeted health counseling and psychological support tailored to the characteristics of each sleep category to address their sleep issues and improve their quality of life.

Resilience, Pain Self-efficacy and Health-related Quality of Life in Greek Hemodialysis Patients: A Cross-sectional Study

Background

Regardless of the recent advances in Chronic Kidney Disease stage 5 (CKD-5) management people on dialysis face significant changes in their quality of life. The present study aimed to examine the relationship between psychological resilience and quality of life in patients undergoing in-center hemodialysis.

Methods

An initial sample of 150 adult patients on hemodialysis for more than 6 months was selected from hospitals in a Southern European country. The study used the Connor-Davidson Resilience Scale (CD-RISC), the Pain Self-Efficacy Questionnaire (PSEQ), and the Kidney Disease Quality of Life (KDQOL-36) questionnaires to assess levels of psychological resilience, pain self-efficacy and quality of life.

Results

The results indicated that higher levels of psychological resilience were associated with higher levels of pain self-efficacy, which in turn led to better quality of life.

Conclusions

The findings suggest that psychological resilience and pain self-efficacy play important roles in the health-related quality of life of people on hemodialysis, regardless of demographic factors such as age and gender. These have implications for practice in CKD-5 management and highlight the importance of addressing psychological factors in dialysis care.

Using Ecological Momentary Assessment to Redefine Postdialysis Fatigue in Patients with Kidney Failure

Background:

Patients with kidney failure have a high symptom burden and many report an acute exacerbation of symptoms immediately following in-center hemodialysis (HD). Very few studies have used ecological momentary assessment (EMA) to examine post-HD patient-centered outcomes.

Methods:

Participants in the Technology Assisted Collaborative Care (TĀCcare) trial completed an automated telephone-administered Daytime Insomnia Symptom Scale (DISS) at 4 time points daily for 7 consecutive days. The DISS yields 4 symptom domain scores: Positive Mood, Negative Mood, Alert Cognition, and Sleepiness/Fatigue. Post-HD symptom domains and item-level scores were compared to similar time points on non-HD days using linear mixed models analyses. Mixed models were also used to explore the association of post-dialysis symptom burden with demographic, psychosocial, hemodialysis treatment, and disease-specific characteristics. All analyses were adjusted for age, race, sex, and Charlson Comorbidity Index

Results:

156 HD patients with available EMA data were evaluated [mean age=58±14 years, 55% men, 51% White]. In the post-HD period, patients reported significantly lower Positive Mood [mean difference (MD)= -0.22, 95% CI (-0.29, -0.14)] and Alert Cognition [MD= -0.13, 95% CI (-0.18, -0.08)] and higher Negative Mood [MD=0.12, 95% CI (0.05, 0.19)] and Sleepiness/Fatigue [MD=0.51, 95% CI (0.42, 0.61)] compared to non-HD days. The mean post-dialysis symptom exacerbation total score was 0.70 ± 1.21, representing an increase of 6% of the maximum scale range. In the post-dialysis period, relative to non-dialysis days, the mean decrease in Positive Mood and Alert Cognition scores equaled 4% and 2% of the maximum scale range respectively; the mean increase in Negative Mood and Sleepiness/Fatigue scores equaled 2% and 9% of the maximum scale range respectively.

Conclusions:

Patients with kidney failure reported worsening of both fatigue and mood symptoms post- HD.

Hemodialysis employing molecular hydrogen (H2) enriched dialysis solution may improve dialysis related fatigue through impact on energy metabolism

Hemodialysis employing molecular hydrogen (H2)-enriched dialysis solution rendered by water electrolysis (E-HD), has been reported to alleviate dialysis-related fatigue, but its association with metabolic profiles remains unclear. Eighty-one patients undergoing standard HD were classified into 3 groups [Group A (n = 25, 30.9%): fatigue with activity reduction-subgroups A1: chronic persistent fatigue (n = 11), A2: fatigue only on dialysis days (n = 14); Group B: fatigue without activity reduction (n = 24, 29.6%); Group C (n = 32, 39.5%): no fatigue], and their changes in fatigue, body composition, and metabolic profiles were studied following 12 months of E-HD. There were no significant differences in baseline characteristics among the groups. Over the 12 months after E-HD initiation, fatigue in Group A significantly decreased, while no changes in Group-B and C. Bio-impedance analysis revealed no significant changes in A1, but significant reductions in body fat and increases in skeletal muscle mass were observed despite no significant weight change in A2. Enrichment analysis suggested significant differences in metabolic pathways such as fatty acid metabolism, citric acid cycle, and glycolysis between Groups A and C at baseline, and these differences were mitigated by E-HD. E-HD could suppress dialysis-related fatigue, through possible involvement of altered energy metabolism of patients. E-HD may represent a new paradigm for uremia treatment beyond traditional solute removal-based dialysis therapies.

Kidney Disease: Improving Global Outcomes (KDIGO) Workshop on the Nurse's Role in Managing the Symptoms of People Receiving Dialysis

Adults with kidney failure receiving dialysis frequently report high symptom burden that can limit life participation and decrease the quality of life. Fatigue, itch, pain, anxiety, depressive symptoms, sleep problems, nausea, vomiting, muscle cramps, breathlessness, and decreased cognition can negatively impact important daily activities. Nurses are the majority health professional group that provides care for people receiving dialysis and have a major role in managing these symptoms. However, routine symptom management by nurses is not universal or standardized in dialysis care. In December of 2023, Kidney Disease: Improving Global Outcomes (KDIGO) held a workshop on the Nurse's Role in Managing the Symptoms of People Receiving Dialysis. The discussions focused on the current barriers nurses face when identifying and assessing symptoms, strategies for identifying symptoms, and the ongoing monitoring and management of symptoms. Nephrology nurses are pivotal in supporting the person with kidney failure receiving dialysis to minimize symptoms, optimize symptom management, decrease dialysis treatment burden, and improve life participation and quality of life.

Post-dialysis fatigue predicts all-cause mortality in patients on chronic hemodialysis

INTRODUCTION

Fatigue is reportedly associated with a poor prognosis in dialysis patients. The aim of the present study was to investigate whether fatigue on dialysis days or non-dialysis days is associated with mortality in patients on chronic hemodialysis.

METHODS

This was a prospective study of 134 hemodialysis patients. The level of fatigue was evaluated using a visual analog scale (VAS). The association between high fatigue evaluated by the highest quartile of the VAS value and all-cause death was investigated.

RESULTS

The fatigue scale score was significantly higher on dialysis than on non-dialysis days. During the follow-up period (median 6.8 years), 42 patients died. Patients with high post-dialysis fatigue in the higher quartiles died more frequently compared to those with in the lower quartiles (p = 0.012). Multivariate Cox regression analysis showed that high post-dialysis fatigue was an independent predictor of all-cause death (adjusted hazard ratio 2.12, 95% confidence interval 1.10-4.07).

CONCLUSION

Higher post-dialysis fatigue is related to increased mortality.

Fatigue in Hemodialysis Patients: A Comparative Analysis with Healthy Controls

This study investigates fatigue and quality of life in hemodialysis patients, examining the influence of demographic and clinical factors on these outcomes. A cohort of 115 hemodialysis patients and 112 healthy controls completed the Modified Fatigue Impact Scale (MFIS), the shorter MFIS-5, and the WHOQOL-BREF quality of life assessment. The findings indicate that hemodialysis patients experience significantly higher levels of fatigue, which correspond with lower quality of life, particularly in the physical and psychological domains, compared to healthy controls. Male patients reported significantly higher levels of fatigue and lower quality of life scores, whereas younger patients demonstrated relatively better outcomes. Extended dialysis sessions exceeding four hours were associated with poorer social well-being, and educational attainment was positively linked with physical and environmental quality of life domains. However, marital status did not show a significant effect. The study validates the consistency between MFIS and MFIS-5 scores, recommending MFIS-5 for time-sensitive clinical use without compromising accuracy. These results underscore the need for individualized, multi-dimensional approaches to fatigue management in hemodialysis patients, emphasizing interventions that address physical, psychological, and social well-being to enhance overall quality of life. The findings highlight specific factors that may guide tailored support strategies to improve patient outcomes in this population.

Insights into effective fatigue reducing interventions in kidney transplant candidates: a scoping review

BACKGROUND

Fatigue is a prevalent and debilitating symptom among kidney transplant candidates (KTCs), significantly affecting their quality of life and overall well-being. Its complexity necessitates a comprehensive approach to manage fatigue in this population.

PURPOSE

To explore the effectiveness of nonpharmacological interventions in reducing fatigue in KTCs.

METHODS

Nonpharmacological interventions targeting fatigue in participants aged ≥18 years, who were either on the kidney transplantation waitlist or eligible candidates, were considered. A database search was conducted in PubMed, Embase, PsycINFO, CINAHL, and Web of Science. Results were reported in accordance with the guidelines provided by the Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocols extension for Scoping Reviews Checklist.

RESULTS

In total, 67 studies were included. Interventions were divided into manipulative and body-based practices, exercise, mind-body therapies, energy healing, and combined interventions. Thirty-eight studies (76%) demonstrated a significant effect on fatigue, with effect sizes ranging from 0.43 to 4.85. Reflexology, massage therapy, progressive muscle relaxation, and acupressure combined with massage therapy showed the strongest significant intervention effects on fatigue and had the strongest study quality. However, the overall study quality was weak, particularly concerning confounding control, blinding procedures, and withdrawals and dropouts.

CONCLUSIONS

Manipulative and body-based interventions showed the strongest significant effects on fatigue with the highest study quality. These interventions underscore the multifactorial nature of fatigue by targeting both its physical and psychological dimensions. Future high-quality research is needed to determine the optimal strategy for managing fatigue in KTCs.

Development and validation of a nomogram to estimate fatigue probability in hemodialysis patients

OBJECTIVE

This study aims to investigate the factors that influence fatigue in hemodialysis (HD) patients and to develop and validate a nomogram to estimate the probability of fatigue in this population.

METHODS

This cross-sectional study collected 453 patients who underwent HD at the tertiary hospital in Hubei, China, from April to December 2023. They were randomly divided into a 70% training group (n = 316) and a 30% validation group (n = 137). In the training set, factors influencing fatigue were screened using multivariate logistic regression analysis, and a nomogram was developed to estimate fatigue probability in HD patients. The discrimination and calibration of the nomogram were validated in both the training and validation sets through the area under the receiver operating characteristic (ROC) curve (AUC) and the Hosmer-Lemeshow (H-L) test.

RESULTS

In the training group, logistic regression showed that age, dialysis vintage, inter-dialysis weight gain, hemoglobin, depression, insomnia, and social support were variables associated with fatigue in HD patients. Based on these factors, a nomogram for assessing fatigue probability in HD patients was developed. The AUC was 0.955 (95% CI: 0.932-0.977) and 0.979 (95% CI: 0.961-0.997) in the training and validation sets. The results from the H-L test indicated a good fit.

CONCLUSION

The nomogram can evaluate fatigue probability in HD patients and may serve as a convenient clinical tool.

Dialysis for Chronic Kidney Failure: A Review

Importance

More than 3.5 million people worldwide and 540 000 individuals in the US receive maintenance hemodialysis or peritoneal dialysis for the treatment of chronic kidney failure. The 5-year survival rate is approximately 40% after initiation of maintenance dialysis.

Observations

Hemodialysis and peritoneal dialysis remove metabolic waste and excess body water and rebalance electrolytes to sustain life. There is no recommended estimated glomerular filtration rate (eGFR) threshold for initiating dialysis, and patient-clinician shared decision-making should help determine when to initiate dialysis. Persistent signs and symptoms of uremia (eg, nausea, fatigue) and volume overload (eg, dyspnea, peripheral edema), worsening eGFR, metabolic acidosis, and hyperkalemia inform the timing of therapy initiation. A randomized clinical trial reported no mortality benefit to starting dialysis at higher eGFR (10-14 mL/min/1.73 m2) vs lower eGFR (5-7 mL/min/1.73 m2) levels. Observational data suggested no differences in 5-year mortality with use of hemodialysis vs peritoneal dialysis. Cardiovascular (eg, arrhythmias, cardiac arrest) and infection-related complications of maintenance dialysis are common. In the US, hemodialysis catheter-related bloodstream infections occur at a rate of 1.1 to 5.5 episodes per 1000 catheter-days and affect approximately 50% of patients within 6 months of catheter placement. Peritonitis occurs at a rate of 0.26 episodes per patient-year and affects about 30% of individuals in the first year of peritoneal dialysis therapy. Chronic kidney failure-related systemic complications, such as anemia, hyperphosphatemia, hypocalcemia, and hypertension, often require pharmacologic treatment. Hypotension during dialysis, refractory symptoms (eg, muscle cramps, itching), and malfunction of dialysis access can interfere with delivery of dialysis.

Conclusions and Relevance

In 2021, more than 540 000 patients in the US received maintenance hemodialysis or peritoneal dialysis for treatment of chronic kidney failure. Five-year survival rate after initiation of maintenance dialysis is approximately 40%, and the mortality rate is similar with hemodialysis and peritoneal dialysis. Decisions about dialysis initiation timing and modality are influenced by patient symptoms, laboratory trajectories, patient preferences, and therapy cost and availability and should include shared decision-making.

Modifiable Factors Associated with Prolonged Dialysis Recovery Time and Fatigue in Hemodialysis Patients

Key Points

A negative change in serum sodium during a dialysis session is an independent factor associated with prolonged dialysis recovery time. Lower hemoglobin is an independent factor associated with fatigue in hemodialysis patients. Hemodiafiltration use in patients age ≥85 years is associated with a longer dialysis recovery time.

Background

Dialysis recovery time (DRT) and fatigue are two important patient-reported outcomes that highly affect hemodialysis patients' well-being and survival. This study aimed to identify all modifiable dialysis-related factors, associated with DRT and fatigue, that could be addressed in future clinical trials.

Methods

This multicenter observational study included adult patients, undergoing chronic hemodialysis for >3 months during December 2023. Patients admitted to hospital, with cognitive problems or active cancer were excluded. DRT was determined by asking over six sessions: How long did it take you to recover from your last dialysis session? Fatigue was assessed using the French-validated Standardized Outcomes in Nephrology-Hemodialysis fatigue scale. Logistic regression analysis assessed the association between DRT >12 hours and fatigue score ≥4 with all dialysis-related factors. A subanalysis of DRT-related factors was performed for very elderly patients aged 85 years and above.

Results

A total of 536 patients and 2967 sessions were analyzed. The mean age was 68.1±14.3 years, 60.9% were male, 33.2% had diabetes, and 63.3% were on hemodiafiltration. The median dialysate sodium was 138 (136–140). The median DRT was 140 (45–440) minutes, and 14.9% of patients had DRT >12 hours. Fatigue score was 3.1±2.3, 18% had no fatigue, and 37.7% had a score ≥4. DRT was significantly associated with fatigue score. In multivariable regression analysis, intradialytic reduction in serum sodium and frequency of dialysis were significantly associated with DRT. Factors associated with fatigue included female sex and lower hemoglobin. In patients aged 85 years and above, hemodiafiltration was associated with prolonged DRT.

Conclusions

Modifiable factors associated with prolonged DRT are not exactly similar to those associated with fatigue. Intradialytic reduction in serum sodium and low frequency of dialysis are two independent factors associated with longer DRT, with hemodiafiltration associated with longer recovery in very elderly patients. The hemoglobin level is the modifiable independent factor associated with fatigue. These modifiable factors can be addressed in future interventional trials to improve patients' outcomes.

Core Patient-Reported Outcomes for Trials in Nephrology

The outcomes reported in trials across all stages of chronic kidney disease (CKD) are highly variable and often do not include outcomes that are directly relevant to patients and caregivers. Frequently, the outcomes reported in trials are often unvalidated surrogate biochemical end points. The omission of outcomes that are meaningful and important to patients can diminish the value of trials in supporting treatment decisions. In response, there have been increasing efforts across many health and medical disciplines to develop core outcome sets, defined as the minimum set of outcomes to be reported in all trials in a specific health area to improve the relevance and consistency of reporting trial outcomes. The international Standardized Outcomes in Nephrology (SONG) initiative was established in 2014 and has since developed seven core outcome sets for different diagnosis and treatment stages of CKD. The core outcomes were based on consensus among patients, caregivers, and health professionals. Each core outcome set includes at least one patient-reported outcome, including fatigue (hemodialysis), life participation (kidney transplantation, peritoneal dialysis, early CKD not yet requiring kidney replacement therapy, children and adolescents, and glomerular disease), and pain (polycystic kidney disease). This article outlines how patient-reported outcomes are currently reported in trials, discusses core patient-reported outcomes that have been established for trials in kidney disease, and outlines strategies for implementing core patient-reported outcomes in trials.

Measuring Social Functioning in Chronic Kidney Disease

Social functioning is a key aspect of daily life and is important to patients living with chronic kidney disease (CKD) and their caregivers. Many patients with CKD experience debilitating symptoms and treatment burden that can diminish their social functioning and thereby overall social health, which is the aspect of a person's well-being relating to their interactions and connections with others. In patients with CKD, symptoms (e.g., fatigue and pain), burden of ongoing treatments (including kidney replacement therapies), and medication side effects can impair social functioning. Having to manage responsibilities of self-management, which can include time-consuming and invasive treatments such as dialysis, can severely limit social functioning in patients with CKD. This can lead to poor social connections at many levels, including with family, friends, peers, and colleagues, and can hinder the development of new relationships. Patients with CKD with poorer social functioning have been reported to have worse quality of life and impaired mental health. Many patients with CKD rely on an informal caregiver-usually a family member or friend-to assist with management of their disease. This can place strain on the caregiver, further limiting opportunities for social connections for both the patient and caregiver. Although social functioning is critical for the overall well-being of patients with CKD, it remains underaddressed clinically, and patient-reported outcome measures (PROMs) to assess social functioning are limited. The objective of this article is to define social functioning, discuss the impacts of social functioning in patients with CKD and their caregivers, outline PROMs that have included assessment of social functioning, and discuss considerations in developing an appropriate PROM to measure social functioning in patients with CKD. This may help to inform the evaluation of interventions and care regarding social functioning within the CKD population.

Development process, clinical utility, and preliminary psychometric evidence of a new tool for screening psychological distress in renal care settings: the Hemodialysis Distress Thermometer (HD-DT)

OBJECTIVE

This study aimed to develop, evaluate the clinical utility, and test the psychometric properties of a new tool - the Hemodialysis Distress Thermometer (HD-DT) - designed to screen self-reported psychological distress and its sources in adults receiving hemodialysis.

METHODS AND MEASURES

Phase 1 focused on the process of developing and evaluating the content validity and clinical utility of the HD-DT using a stepwise mixed-methods approach; in Phase 2, the measurement properties of the European Portuguese version of the HD-DT were tested against reference measures in a cross-sectional study (n = 134 people on hemodialysis); while in Phase 3 the HD-DT was translated and culturally adapted into American English using forward-backward translation and review by a panel of experts.

RESULTS

Qualitative findings suggested that the HD-DT was perceived by feedback panels as practical and useful for rapidly screening psychological distress in nephrology centers. The European Portuguese version of this new tool showed good test-retest reliability and high diagnostic accuracy using a cutoff point of ≥ 6 for total distress. High convergent validity was found with reference measures that assess psychological health, and symptoms of anxiety and depression.

CONCLUSION

This study highlights the potential clinical utility of the HD-DT as an acceptable, reliable, and valid measure that can be used by health psychologists in clinical practice and research in renal care settings. Data collection to validate the American English version of the HD-DT is currently underway.

Live music during haemodialysis: A multiple methods randomised controlled pilot study

BACKGROUND

Fatigue is an immense problem among patients undergoing haemodialysis and is associated with anxiety and depression. Live music used in different hospital settings has shown promising effects, but the feasibility and potential effectiveness of live music during haemodialysis are unknown.

OBJECTIVES

To evaluate the feasibility, the participants' musical experience and potential effectiveness of live music on patients' levels of fatigue, relaxation, anxiety, depression, treatment satisfaction and work engagement among nurses.

DESIGN

A pilot randomised controlled trial evaluated with a multiple methods design.

PARTICIPANTS

Two clusters of 12 patients were each randomised to receive either 30 min of live music once a week during haemodialysis or usual care over a period of 6 weeks.

MEASUREMENTS

The primary outcome was patients' immediate fatigue. Other outcomes were patients' long-term and post-dialysis fatigue, relaxation, anxiety, depression, treatment satisfaction and work engagement among nurses. Observations and semi-structured interviews with patients, nurses and musicians were conducted to gain an in-depth understanding of the musical experience as well as feasibility.

RESULTS

The study was feasible and detected significant differences on immediate fatigue (p < 0.001) and anxiety (p < 0.012) in the intervention group compared to controls. Among 17 nurses, a significant difference was found in Dedication (p < 0.024). Furthermore, live music gave patients an uplifting experience, bringing joy and relaxation and the nurses experienced a sense of quietness in a stressful day.

CONCLUSIONS

Providing live music performed by professional musicians in a haemodialysis setting is feasible and showed a significant effect on immediate fatigue and anxiety compared to controls.

Individual evaluation of fatigue at work to enhance the safety performance in the construction industry: A systematic review

The construction industry is recognized as one of the most hazardous industries globally due to the dynamic on site activities and labour-intensive characteristics. The construction tasks are physically and cognitively demanding therefore the construction workers are prone to work fatigue which compromises safety performance. The evaluation of fit for duty, or fitness for work (FFW) aims to determine if workers are at risk of adverse impacts of ill-health, injury or accidents. This systematic review aimed to critically summarize up-to-date measures and evaluation tools that were employed to monitor work fitness or fatigue specifically among construction workers. Adhering with the PRISMA protocol, three databases were searched from the inception to 2022, with a total combination of 37 keywords, concluding to the selection of 20 relevant articles. The Mixed Method Appraisal Tool (MMAT) was used as the guide for the study appraisal. A total of 20 articles were reviewed, published from 2008-2022. Majority of the studies employed experimental design. The review identified the subjective evaluation scales and objective measurement tool. The subjective self-response questionnaires can be categorized into single dimension or multidimension covering both physical and mental fitness; whereas the objective measurement tool can be categorized into physiological metrics, physical and cognitive performance measure. The available scientific evidence has raised the relevant issues for on-site practicality and potentially guide the formulation of evidence-based guidelines for the FFW assessment in the construction industry.

The effect of footbath applied to patients receiving hemodialysis treatment on comfort, fatigue, and dialysis symptoms: A randomized controlled study

INTRODUCTION

This study aimed to evaluate the effect of warm water footbaths on comfort, fatigue, and dialysis symptoms in patients undergoing hemodialysis.

METHODS

Data were collected from a total of 58 patients, 31 in the intervention group and 27 in the placebo group. The data in the study are collected using the intervention and control group informed volunteer Form, Patient Demonstration Form, foot Bath Application Monitoring Chart, fatigue VAS Scale Form, Dialysis Symptom Index, and Hemodialysis Comfort Scale (HCS).

RESULTS

In the second follow-up in the intervention group, HCS was determined to significantly increase all sub-size and total score averages by the first trace (p < 0.05). VAS fatigue point averages were significantly lower (p < 0.05) in the intervention group.

CONCLUSION

It was determined that the footbath applied to patients who received hemodialysis treatment increased comfort and reduced fatigue and dialysis symptoms.

The effect of foot reflexology on fatigue in hemodialysis patients: a meta-analysis study

OBJECTIVE

this meta-analysis study analyzed the effect of foot reflexology on fatigue in hemodialysis patients by combining the results of independent studies on this subject.

METHOD

meta-analysis study. A literature search was conducted in seven databases. The methodological quality of the included studies was assessed using tools proposed by the Joanna Briggs Institute. Comprehensive Meta-Analysis v3 was used for meta-analysis.

RESULTS

No information was provided in the investigated studies about the possible side effects and negative effects of foot reflexology. (1) This study found that foot reflexology reduced fatigue levels. (2) The 10-session foot reflexology was the most effective. (3) This study will guide nurses and health workers. (4) Reflexology is one of the non-pharmacological methods used to relieve fatigue.

Interventions for fatigue in people with kidney failure requiring dialysis

BACKGROUND

Fatigue is a common and debilitating symptom in people receiving dialysis that is associated with an increased risk of death, cardiovascular disease and depression. Fatigue can also impair quality of life (QoL) and the ability to participate in daily activities. Fatigue has been established by patients, caregivers and health professionals as a core outcome for haemodialysis (HD).

OBJECTIVES

We aimed to evaluate the effects of pharmacological and non-pharmacological interventions on fatigue in people with kidney failure receiving dialysis, including HD and peritoneal dialysis (PD), including any setting and frequency of the dialysis treatment.

SEARCH METHODS

We searched the Cochrane Kidney and Transplant Register of Studies up to 18 October 2022 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov.

SELECTION CRITERIA

Studies evaluating pharmacological and non-pharmacological interventions affecting levels of fatigue or fatigue-related outcomes in people receiving dialysis were included. Studies were eligible if fatigue or fatigue-related outcomes were reported as a primary or secondary outcome. Any mode, frequency, prescription, and duration of therapy were considered.

DATA COLLECTION AND ANALYSIS

Three authors independently extracted data and assessed the risk of bias. Treatment estimates were summarised using random effects meta-analysis and expressed as a risk ratio (RR) or mean difference (MD), with a corresponding 95% confidence interval (CI) or standardised MD (SMD) if different scales were used. Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

MAIN RESULTS

Ninety-four studies involving 8191 randomised participants were eligible. Pharmacological and non-pharmacological interventions were compared either to placebo or control, or to another pharmacological or non-pharmacological intervention. In the majority of domains, risks of bias in the included studies were unclear or high. In low certainty evidence, when compared to control, exercise may improve fatigue (4 studies, 217 participants (Iowa Fatigue Scale, Modified Fatigue Impact Scale, Piper Fatigue Scale (PFS), or Haemodialysis-Related Fatigue scale score): SMD -1.18, 95% CI -2.04 to -0.31; I2 = 87%) in HD. In low certainty evidence, when compared to placebo or standard care, aromatherapy may improve fatigue (7 studies, 542 participants (Fatigue Severity Scale (FSS), Rhoten Fatigue Scale (RFS), PFS or Brief Fatigue Inventory score): SMD -1.23, 95% CI -1.96 to -0.50; I2 = 93%) in HD. In low certainty evidence, when compared to no intervention, massage may improve fatigue (7 studies, 657 participants (FSS, RFS, PFS or Visual Analogue Scale (VAS) score): SMD -1.06, 95% CI -1.47, -0.65; I2 = 81%) and increase energy (2 studies, 152 participants (VAS score): MD 4.87, 95% CI 1.69 to 8.06, I2 = 59%) in HD. In low certainty evidence, when compared to placebo or control, acupressure may reduce fatigue (6 studies, 459 participants (PFS score, revised PFS, or Fatigue Index): SMD -0.64, 95% CI -1.03 to -0.25; I2 = 75%) in HD. A wide range of heterogenous interventions and fatigue-related outcomes were reported for exercise, aromatherapy, massage and acupressure, preventing our capability to pool and analyse the data. Due to the paucity of studies, the effects of pharmacological and other non-pharmacological interventions on fatigue or fatigue-related outcomes, including non-physiological neutral amino acid, relaxation with or without music therapy, meditation, exercise with nandrolone, nutritional supplementation, cognitive-behavioural therapy, ESAs, frequent HD sections, home blood pressure monitoring, blood flow rate reduction, serotonin reuptake inhibitor, beta-blockers, anabolic steroids, glucose-enriched dialysate, or light therapy, were very uncertain. The effects of pharmacological and non-pharmacological treatments on death, cardiovascular diseases, vascular access, QoL, depression, anxiety, hypertension or diabetes were sparse. No studies assessed tiredness, exhaustion or asthenia. Adverse events were rarely and inconsistently reported.

AUTHORS' CONCLUSIONS

Exercise, aromatherapy, massage and acupressure may improve fatigue compared to placebo, standard care or no intervention. Pharmacological and other non-pharmacological interventions had uncertain effects on fatigue or fatigue-related outcomes in people receiving dialysis. Future adequately powered, high-quality studies are likely to change the estimated effects of interventions for fatigue and fatigue-related outcomes in people receiving dialysis.

Assessing Fatigue in Patients Receiving Kidney Replacement Therapy Using PROMIS Computer Adaptive Testing

RATIONALE & OBJECTIVE

Fatigue is a debilitating symptom for many patients receiving kidney replacement therapy (KRT). Patient-reported outcome measures can help clinicians identify and manage fatigue efficiently. We assessed the measurement characteristics of the Patient Reported Outcome Measurement Information System (PROMIS)-Fatigue Computer Adaptive Test (PROMIS-F CAT) in patients receiving KRT using the previously validated Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaire.

STUDY DESIGN

Cross-sectional study.

SETTING & PARTICIPANTS

198 adults treated with dialysis or recipients of a kidney transplant in Toronto, Canada.

PREDICTORS

Demographic data, FACIT-F scores, KRT type.

OUTCOME

Measurement properties of PROMIS-F CAT T scores.

ANALYTICAL APPROACH

Reliability and test-retest reliability were assessed using standard errors of measurement and intraclass correlation coefficient (ICC), respectively. Construct validity was assessed using correlation and comparisons across predefined groups expected to have different levels of fatigue. Receiver operating characteristic (ROC) curves were used to assess the discrimination of PROMIS-F CAT, with clinically relevant fatigue defined by a FACIT-F score of≤30.

RESULTS

Of the 198 participants, 57% were male, the mean±SD age was 57±14 years; 65% had received a kidney transplant. Based on the FACIT-F score, 47 patients (24%) had clinically relevant fatigue. PROMIS-F CAT and FACIT-F were strongly correlated (ρ =-0.80, P<0.001). PROMIS-F CAT had excellent reliability (>0.90 for 98% of sample), and good test-retest reliability (ICC=0.85). The ROC analysis demonstrated outstanding discrimination (area under ROC=0.93 [95%, CI 0.89-0.97]). A PROMIS-F CAT cutoff score of≥59 accurately identified most patients with clinically relevant fatigue (sensitivity=0.83; specificity=0.91).

LIMITATIONS

A convenience sample of clinically stable patients. FACIT-F items are a part of the PROMIS-F item bank, although there was minimal overlap with only 4 FACIT-F items completed in PROMIS-F CAT.

CONCLUSIONS

PROMIS-F CAT has robust measurement properties with low question burden to assess fatigue among patients with KRT.

Quality of Life and Kidney Function in Older Adults: Prospective Data of the SCOPE Study

A longitudinal alteration in health-related quality of life (HRQoL) over a two-year period and its association with early-stage chronic kidney disease (CKD) progression was investigated among 1748 older adults (>75 years). HRQoL was measured by the Euro-Quality of Life Visual Analog Scale (EQ-VAS) at baseline and at one and two years after recruitment. A full comprehensive geriatric assessment was performed, including sociodemographic and clinical characteristics, the Geriatric Depression Scale-Short Form (GDS-SF), Short Physical Performance Battery (SPPB), and estimated glomerular filtration rate (eGFR). The association between EQ-VAS decline and covariates was investigated by multivariable analyses. A total of 41% of the participants showed EQ-VAS decline, and 16.3% showed kidney function decline over the two-year follow-up period. Participants with EQ-VAS decline showed an increase in GDS-SF scores and a greater decline in SPPB scores. The logistic regression analyses showed no contribution of a decrease in kidney function on EQ-VAS decline in the early stages of CKD. However, older adults with a greater GDS-SF score were more likely to present EQ-VAS decline over time, whereas an increase in the SPPB scores was associated with less EQ-VAS decline. This finding should be considered in clinical practice and when HRQoL is used to evaluate health interventions among older adults.

Serum 25-Hydroxyvitamin D Level Is Negatively Associated with Fatigue in Elderly Maintenance Hemodialysis Patients

INTRODUCTION

Chronic kidney disease-mineral and bone disorder (CKD-MBD) is frequently observed in maintenance hemodialysis (MHD) patients and is associated with fracture, muscle weakness, malnutrition, etc.; however, relationships of CKD-MBD markers and fatigue are not well established.

METHODS

This was a cross-sectional study including 244 MHD patients (89 elders) from July to September 2021 in the First Affiliated Hospital of Shandong First Medical University. CKD-MBD markers and other clinical data were collected from medical records. Fatigue in the past week was measured by Standardized Outcomes in Nephrology-Hemodialysis (SONG-HD) fatigue measure; fatigue at the end of hemodialysis was measured by numeric rating scale (NRS). Spearman correlation, linear regression, and robust linear regression were.

RESULTS

In all MHD patients, lg[25(OH)D] (nmol/L) was negatively correlated with SONG-HD score (β = -1.503, 95% CI: -2.826 to 0.18, p = 0.026) and NRS score (β = -1.532, p = 0.04) in multiple regression models adjusting for sex, age, and all CKD-MBD characters; but no correlations were found on univariate regression or in other multiple regression models. Interaction effects between age ≥65 years and lg(25[OH]D [nmol/L]) in terms of fatigue scores were significant based on multiple linear regressions (SONG-HD score β = -3.613, p for interaction = 0.006; NRS score β = -3.943, p for interaction = 0.008). Compared with non-elderly patients, elderly patients were with higher ACCI scores (7 [6, 8] vs. 4 [3, 5], p < 0.001), higher SONG-HD scores (3 [2, 6] vs. 2 [1, 3], p < 0.001), higher NRS score (4 [2, 7] vs. 3 [1, 5], p < 0.001), lower serum phosphate levels (1.65 [1.29, 2.10] vs. 1.87 [1.55, 2.26] mmol/L, p = 0.002), and lower serum iPTH levels (160.6 [90.46, 306.45] vs. 282.2 [139, 445.7] pg/mL, p < 0.001). There were no differences in serum calcium, alkaline serum, or 25(OH)D levels between the two groups. In elderly patients, lg[25(OH)D] was negatively correlated with SONG-HD score (β = -3.323, p = 0.010) and NRS score (β = -3.521, p = 0.006) on univariate linear regressions. Following adjustment for sex, age, and all CKD-MBD characters, lg[25(OH)D] was negatively correlated with SONG-HD scores (multiple linear regression β = -4.012, p = 0.004; multiple robust regression β = -4.012, p = 0.003) or NRS scores (multiple linear regression β = -4.104, p = 0.002; multiple robust regression β = -4.104, p = 0.001). There were no significant correlations between fatigue scores and other CKD-MBD markers (calcium, phosphate, lgiPTH, alkaline phosphatase) in elderly MHD patients, on either univariate linear regressions or multiple regressions.

CONCLUSION

Serum 25(OH)D level is negatively associated with fatigue in elderly MHD patients.

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.

Frailty as a dynamic process in a diverse cohort of older persons with dialysis-dependent CKD

This study examines frailty status evolution observed in a two-year follow-up of a cohort of older persons (age ≥65) with chronic kidney disease (CKD) undergoing maintenance hemodialysis (HD) treatment. Frailty, a geriatric syndrome that connotes a state of low physiologic reserve and vulnerability to stressors, is associated with increased risk for multiple adverse health outcomes in studies of persons with CKD as well as older persons in the general population. The Fried frailty index defines frailty as the presence of 3 or more of 5 indicators-recent unintentional weight loss, slowed gait speed, decreased muscle strength, self-reported exhaustion, and low physical activity. In the seminal work by Fried and colleagues, persons who were characterized by 1-2 of the Fried index criteria were termed "pre-frail" and considered at risk for subsequently becoming frail, potentially providing insight regarding intervention targets that might slow or prevent individuals' transition from pre-frail to frail status. Other less frequently studied types of transitions may also be informative, including "recovery or reversion" (improvement) by people whose longitudinal assessments indicate movement from frailty to prefrailty or robust, or from prefrailty to robust. These status changes are also a potential source of insights relevant for prevention or remediation of frailty, but research focusing on the various ways that individuals may transition between frailty states over time remains limited, and no previous research has examined varying patterns of frailty status evolution in an older cohort of persons with dialysis-dependent CKD. In a study cohort of dialysis-dependent older persons, we characterized patterns of frailty status evolution by age, sex, race/ethnicity, and treatment vintage; by longitudinal profiles of non-sedentary behavior; and by self-report indicators relevant for dimensions emphasized in the Age-Friendly 4Ms Health System (What Matters, Mobility, Mentation). Our study suggests that strategies to promote resiliency among older persons with dialysis-dependent CKD can be informed not only by frailty status transition that indicates improvement over time but also by older adults' maintenance of (stable) robust status over time, and we concur that inclusion of both frailty and resilience measures is needed in future longitudinal studies and clinical trials.

Systematic surveillance of patient-reported symptoms of viral respiratory tract infectious Syndromes in diverse populations

BACKGROUND

Patient reported outcome measures (PROM) can improve patient care and be crucial for symptom tracking especially during disease outbreaks. FLU-PRO Plus is a validated PROM used to track viral respiratory symptoms. Our study aimed to evaluate the feasibility of using FLU-PRO© Plus, to track symptoms across three healthcare systems.

METHODS

The prospective, longitudinal study recruited adults between February-May 2021 from HealthPartners Institute (HP), Kaiser Permanente Georgia (KPGA), and Kaiser Permanente Mid-Atlantic States (KPMAS). Adult members were eligible if they had a positive lab or diagnosis for either COVID-19 or influenza-like illness (ILI) or exhibited 2 + viral respiratory symptoms. Descriptive statistics were calculated to describe the patient characteristics for participants that were eligible for FLU-PRO Plus, successfully contacted, attempted to log in to the FLU-PRO Plus website, and participants who completed FLU-PRO Plus Day 1. Bivariable and multivariable logistic regression using PROC GLIMMIXX investigated the patient characteristics associated with (1) successful contact and (2) FLU-PRO Plus Day 1 completion.

RESULTS

We identified a total of 15,650 eligible participants during the enrollment period: 9,582 from HP, 1,740 from KPGA, and 4,328 from KPMAS. Among the total of 409 eligible adults who attempted to participate in FLU-PRO Plus, 317 completed FLU-PRO Plus Day 1. Among the 317 individuals that completed FLU-PRO Plus Day 1, 205 (67.5%) were diagnosed with COVID-19; 112 adults diagnosed with COVID-19 completed FLU-PRO Plus Day 14. Among adults successfully contacted, adults aged 35-64 (OR = 1.40, 95% CI 1.05, 1.87), females (OR = 1.77, 95% CI 1.38, 2.27), and adults diagnosed with COVID-19 (OR = 1.66, 95% CI 1.27, 2.17) had higher odds of completing FLU-PRO Plus Day 1; Asian adults (OR = 0.38, 95% CI 0.19, 0.76) and Black and African American adults (OR = 0.33, 95% CI 0.19, 0.76) had lower odds compared to White adults.

CONCLUSION

Our study reports on the feasibility of patients across three integrated healthcare systems utilizing FLU-PRO Plus to monitor their respiratory symptoms. Patient reported outcome measures (PROM) can improve patient care, quality of life, and reduce the strain of limited resources on healthcare systems. Future FLU-PRO Plus studies should develop an implementation strategy to fully integrate FLU-PRO Plus within clinical care and patient management.

Impact of hemodialysis solutions containing different levels of molecular hydrogen (H2) on the patient-reported outcome of fatigue

Background

Reportedly, dialysis solutions containing molecular hydrogen (H2) might ameliorate patient-reported fatigue in hemodialysis (HD) patients. However, it is unknown whether its impact might differ with different H2 levels.

Method

This single-arm, prospective observational study examined 105 patients on chronic HD (62 males; mean age, 66 years; mean HD duration, 117 months). All patients were originally treated with an HD solution with 47 ppb (mean) H2 for more than 12 months, followed by an HD solution with 154 ppb (mean) H2 for 8 weeks. Baseline and changes in subjective fatigue status rated on a numerical rating scale (NRS) were assessed before the start of the study (baseline) and 8th week of the study.

Results

Patients were classified into three groups according to the presence of subjective fatigue at baseline: Group A (15.2%), presence of fatigue on both HD and HD-free days; Group B (28.6%), fatigue only on HD days; and Group C (56.2%), freedom from fatigue. In Group A, NRS scores during the 8-week period were significantly decreased as compared with 0 week, at the 4th and 8th week on HD days, and at the 8th week on HD-free day, respectively. While no consistent changes were found in other groups. At the 8th week, 64 patients (61%) presented absence of or decrease in the NRS score of fatigue, while the rest of patients did not present the decrease in NRS (the non-improved: 39%). Regarding the factors related to the non-improved, prescription of antihypertensive agents was a significant independent risk factor by multivariate analysis, indicating the possible involvement of excess fall in blood pressure (BP) in those patients.

Conclusion

Amelioration of the patient-reported outcome of fatigue might be influenced by H2 levels in the HD solution, and the optimal H2 level in the dialysate needs to be elucidated in consideration of clinical type of fatigue and BP control status.

What are the qualitative experiences of people affected by kidney failure receiving haemodialysis?

BACKGROUND

People affected by kidney failure receiving haemodialysis experience complexity within their health condition unlike any other chronic illness or condition. Kidney failure impacts the individual in all areas of their life including relationships and activities of daily living.

OBJECTIVE

To conduct a meta-aggregation of studies about the lived experiences of people with kidney failure receiving haemodialysis.

DESIGN

Using PRISMA Guidelines, six databases (CINAHL, ClinicalTrials.gov, Cochrane Library, MEDLINE, PsycINFO, and Scopus) were comprehensively searched using keywords and subject headings from January 1990 to October 2021. Articles were assessed according to prespecified eligibility criteria. Data extraction and quality appraisal was conducted. A meta-aggregation of qualitative findings was conducted using the Joanna Briggs Institute methodology for meta-aggregation.

RESULTS

Of the 9409 articles screened, 55 studies were included. This represented a total of 188 findings across 45 categories representing a range of unmet supportive care needs. The meta-aggregation identified 11 synthesised findings broadly related to psychological/emotional needs, physical needs, social needs, interpersonal/intimacy needs, patient-clinician communication needs, family related needs, health system/information needs, spiritual needs, daily living needs, practical needs and daily living needs.

CONCLUSIONS

This meta-aggregation has identified that people affected by kidney failure can experience a range of unmet supportive care needs. It was evident that living with kidney failure and receiving haemodialysis impacted a person's sense of self, introduced practical needs and other complex needs which were not being addressed in existing services. This review has highlighted important implications for clinical practice and future research directions.

The critical role of mixed methods research in developing valid and reliable patient-reported outcome measures

Randomised controlled clinical trials provide the gold standard for evidence underpinning clinical guidelines and patient centred care. However, this is only true when they are robustly designed, conducted and reported and then only if they include outcomes that are important to patients and clinicians. Important outcomes include those that measure impact on patient experience, quality of life, overall well-being, and physical, social, cognitive and emotional functioning, all of which require patient reported outcome measures (PROMs). Patient centred care must be underpinned by objective evidence of the effect of interventions on outcomes that are important to patients. Evidence for patient reported outcomes must be supported by valid and reliable PROMs. Importantly the PROM must reflect patient experience of the impact of the intervention on the outcome and enable quantitative evaluation of that impact. The purpose of this paper is to highlight the critical role of mixed methods research in developing PROMs that are valid (measure what they purport to measure), acceptable to those reporting the outcome and able to reliably detect meaningful differences between individuals with different conditions or severity and with time. This can only be achieved through a structured mixed methods program combining qualitative and quantitative research techniques.

Cancer-related fatigue measures in palliative care: A psychometric systematic review

INTRODUCTION

In palliative care, the prevention and relief of fatigue are regarded as crucial goals in patients with cancer.

METHODS

A systematic review was carried out according to the COnsensus-based Standards for the selection of health status Measurement INstruments methodology. Searches were conducted in Medline (through PubMed), Web of Science, Open Gray, Scielo, Cochrane, CINAHL and EMBASE. All instruments found in each study were assessed using the COnsensus-based Standards for the selection of health status Measurement INstruments checklist and Grading of Recommendations, Assessment, Development and Evaluation approach.

RESULTS

A total of 5598 articles were identified in the different databases. In total, 57 studies describing 19 instruments were included in this study. The main properties evaluated were internal consistency, cross-cultural validity, hypotheses testing and responsiveness. All studies were evaluated with the Strobe scale with a score greater than 6 points.

CONCLUSIONS

According to the quality methodological results, Edmonton Symptom Assessment System, Problems and Needs in Palliative Care Questionnaire, European Organisation for Research and Treatment of Cancer Quality of Life 15-item Questionnaire for Palliative Care and Palliative Care Quality of Life Instrument are the recommended instruments used for assessing cancer-related fatigue in palliative care.

Evaluation of Fatigue’s Effect and Severity in Hemodialysis Patients

Aim: In this study, it was aimed to evaluate the effect and severity of fatigue levels in hemodialysis patients. Methods: This cross-sectional study was conducted on 130 patients who applied to Hemodialysis units between 01 November-01 December 2019. Piper Fatigue Scale, Fatigue Impact Scale, and Fatigue Severity Scale were used as data collection tools. In statistical analysis, Student's t-test and variance analysis were used. Pearson correlation coefficient was calculated to evaluate the relationship between the variables. Results: It is found that hemodialysis patients got the highest score on Piper Fatigue Scale from Piper Fatigue Scale - Affect (5.48±2.85) and patients felt moderately tired. Of the patients, 43.1% stated that ‘dialysis’ was the most important reason that contributes directly or causes their fatigue, and 23.1% stated that the best thing they found to reduce their fatigue was to sleep. Hemodialysis patients got the highest score on the Fatigue Impact Scale from the psychosocial (35.42±18.67) effect dimension. The mean score of the patients' Fatigue Impact Scale was 4.84±1.93. The Piper Fatigue Scale - Behavior, Piper Fatigue Scale - Affective, Piper Fatigue Scale - Sensory and Piper Fatigue Scale - Cognitive Dimension Scores, Fatigue Impact Scale - Cognitive, Fatigue Impact Scale - Physical and Fatigue Impact Scale - Psychosocial Dimension and Fatigue Impact Scale Total Scores and Fatigue Severity Scale Scores in Chronic Renal Failure patients with a chronic disease were significantly higher than in patients without chronic disease. The Fatigue Impact Scale - Cognitive, Fatigue Impact Scale - Physical, and Fatigue Impact Scale - Psychosocial dimensions, Fatigue Impact Scale total scores, and Fatigue Severity Scale scores in patients diagnosed with anemia were significantly higher than in those without anemia. Conclusion: In our study, patients over 65 years of age and those with chronic diseases other than Chronic Renal Failure had higher levels and greater impact and severity of fatigue. Keywords: dialysis, fatigue, severity, hemodialysis

Energy conservation education intervention for people with end-stage kidney disease receiving haemodialysis (EVEREST): protocol for a cluster randomised control trial

INTRODUCTION

Multiple symptoms occur in people with kidney failure receiving haemodialysis (HD) and these symptoms have a negative impact on health-related quality of life (HRQoL). Fatigue, the most common symptom, is debilitating and difficult to manage. Educational interventions involving energy conservation strategies are helpful in reducing fatigue, however the effectiveness of energy conservation has not been previously studied in those receiving HD. The aim of this study is to evaluate the effectiveness of an energy conservation education intervention for people with end-stage kidney disease receiving HD (EVEREST trial).

METHODS AND ANALYSIS

A pragmatic cluster randomised control trial with repeated measure will be used. One hundred and twenty-six participants from tertiary level dialysis centre will be cluster randomised to the intervention and control group according to HD treatment day. The intervention group will receive usual care along with a structured energy conservation education programme over 12 weeks comprising three individual face-to-face educational intervention sessions, one booster session and a booklet. The control group will receive usual care from their healthcare providers and a booklet at the end of the study. The primary outcome is fatigue, and the secondary outcomes are other Chronic Kidney Disease (CKD) symptoms, occupational performance and HRQoL. Intention-to-treat analysis will occur and will include a change in primary and secondary outcomes.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Human Research Committee of the Griffith University and Nepal Health Research Council. The results of this research will be published and presented in a variety of forums.

Can passive pedaling improve sexual function in patients under hemodialysis? A randomized clinical trial

To investigate the effect of passive pedaling with mini bike on sexual function in patients under hemodialysis. This study was a randomized clinical trial. Thirty-seven patients undergoing hemodialysis were assigned to the intervention (n = 20) and control (n = 17) groups by the stratified block randomization method. The intervention group exercised with a mini bike that was automatic and tuned for patients during the first 2 h of dialysis, twice a week for 20 min each time, for 3 months. The International Index of Erectile Function and Female Sexual Function Index were used to assess the sexual function in the first, second, and third months during the intervention and one month after the intervention. A higher score indicates a better sexual function. Repeated measure ANOVA, Chi-square and Fisher exact tests, independent t, and Mann-Whitney U tests were used for data analysis. The SPSS software version 22 was used for data analysis. Sexual function scores of the intervention group were 35.9 at the beginning of the study, 34.1 in the first month, 37.4 in the second month, 34.8 in the third month, and 31.7 one month after the study. There was no significant difference in the scores of sexual function in the intervention group during the study. The mean scores of sexual function in the control group were 34.5, 34.4, 34.9, 33.8, and 33.9 at the beginning of the study, in the first month, in the second month, in the third month, and one month after the study, respectively (p > 0.05). There was no significant difference between the two groups in terms of sexual function scores during and after the intervention (p > 0.05). Passive pedaling with mini-bike had no effect on sexual function of hemodialysis patients.

Effect of Foot Reflexology on Sexual Function of Patients under Hemodialysis: A Randomized Parallel Controlled Clinical Trial

INTRODUCTION

Hemodialysis patients experience sexual dysfunction due to the nature of their disease and its complications. Dialysis patients have reported sexual dysfunction as one of the most important stressors, which leads to many psychological and physiological problems. Sexual function in hemodialysis patients has been improved with pharmaceutical and nonpharmacological therapies. Foot reflexology is a complementary and alternative treatment that can be used in conjunction with contemporary care. By activating the chemical nerve system, reflexology may balance enzymes and regulate endocrine function.

OBJECTIVES

To determine the effect of foot reflexology on the sexual function of hemodialysis patients.

METHODS

This randomized controlled trial was conducted on 47 patients on chronic hemodialysis referred to Imam Reza Hospital in Sirjan, Iran, who were divided into two groups of reflexology (n = 24; male = 19 and female = 5) and sham (n = 23; male = 18, and female = 5). The intervention group received foot reflexology during dialysis for four weeks, three times a week, 30 minutes each time (15 minutes per foot). The sham group received nonspecific foot massage without applying pressure on standard reflex points with the same condition and duration as the intervention group. The international index of erectile function and female sexual function index was assessed before, immediately, and one month after the intervention.

RESULTS

The results showed that immediately after the intervention, male orgasm function, sexual desire, and intercourse satisfaction in the reflexology group was significantly higher than those of the sham group. There was no significant difference between the two groups regarding erectile function and overall satisfaction. Furthermore, there was no significant difference between the two groups in terms of different aspects of female sexual function.

CONCLUSIONS

Foot reflexology, as an effective intervention treatment, can reduce some aspects of sexual dysfunction of male patients under hemodialysis.

Amelioration of fatigue in chronic dialysis patients with dialysis solution employing electrolyzed water containing molecular hydrogen (H2) and its association with autonomic function balance

Background

Enhanced oxidative stress is involved with fatigue in hemodialysis (HD) patients. Molecular hydrogen (H2) could improve the redox status. Thus, the study examines whether HD solution rendered by electrolyzed water containing H2 (E-HD) could impact the fatigue and autonomic balance of patients.

Methods

This single-arm, prospective observational study examined 95 patients on chronic HD (54 males; mean age and HD duration; 71.4 years and 10.6 years). Fatigue status on HD and HD-free days was compared between control HD (CHD) and 8 weeks after commencement of E-HD, using a visual analog scale (VAS) and an original scale. Autonomic balance was analyzed with the degree of activities of the sympathetic and parasympathetic nervous system via frequency analysis of a continuous beat interval.

Results

Patients were classified into three groups according to the presence of subjective fatigue during the period of CHD: Group A (40.0%), fatigue only on HD days; Group B (11.6%), presence of fatigue on both HD and HD-free days; and Group C (48.4%), freedom from fatigue. During the 8-week observation period of E-HD, VAS scores were significantly decreased on HD days in Group A, while Group B showed no significant changes in VAS on HD days, but significant decreases on HD-free days. No consistent changes were found in Group C. Significant increases in percentages of patients who reported absence of fatigue were seen in Group A on HD days and in Group B on HD-free days in week 8. Regarding changes in autonomic balance parameters after E-HD commencement, a positive correlation was identified between changes in VAS and autonomic balance in Group A.

Conclusion

E-HD may ameliorate fatigue in patients with subjective symptoms on HD and HD-free days. The influence of autonomic balance by E-HD and its impact on fatigue needs to be elucidated.

Fatigue in CKD: Epidemiology, Pathophysiology, and Treatment

Fatigue is a commonly reported and debilitating symptom among patients with CKD, yet little is known about its epidemiology, pathogenesis, and treatment. Various measurement tools have been used in published studies to identify and quantify fatigue. These include several single-item measures embedded in longer questionnaires for assessing depression, quality of life, or symptom burden in patients with kidney disease. Approximately 70% of patients with CKD report fatigue, with up to 25% reporting severe symptoms. Patient-reported fatigue is associated with death, dialysis initiation, and hospitalization among individuals with CKD. The pathophysiology is multifactorial and likely includes decreased oxygen delivery and increased reliance on anaerobic metabolism, thus generating lactic acidosis in response to exertion; the effects of chronic metabolic acidosis and hyperphosphatemia on skeletal muscle myocytes; protein-energy wasting and sarcopenia; and depression. Physical activity has been shown to improve fatigue in some small but promising trials, and so should be recommended, given the additional benefits of exercise. Targeting higher hemoglobin levels with erythropoiesis-stimulating agents may improve fatigue, but potential adverse cardiovascular effects preclude their use to solely treat fatigue without the presence of another indication. Current guidelines recommend cautious individualization of hemoglobin targets for those at low cardiovascular risk who still experience fatigue or functional limitation despite a hemoglobin level of 10 g/dl. Sodium bicarbonate supplementation for the treatment of metabolic acidosis may also improve functional status. Selective serotonin reuptake inhibitors have not been consistently shown to improve fatigue in patients with kidney disease, but an ongoing trial will evaluate the effect of alternative antidepressant drug and behavioral activation therapy on fatigue in patients with CKD. Overall, more research is needed to further clarify underlying mechanisms of fatigue and identify effective, targeted treatments for patients with CKD.

Amelioration of hemodialysis-induced oxidative stress and fatigue with a hemodialysis system employing electrolyzed water containing molecular hydrogen

Background

A novel hemodialysis (HD) system employing electrolyzed water containing molecular hydrogen (E-HD) has been developed to improve the bio-compatibility of HD. This study examined the impact of E-HD on changes in redox state during HD and HD-related fatigue.

Method

This single-arm, prospective observational study examined 63 patients on chronic HD (41 males; mean age, 72 ± 9 years; median duration of HD, 7 years). Redox parameters (serum myeloperoxidase [MPO], malondialdehyde-protein adduct [MDA-a], thioredoxin 1 [TRX]) during HD were compared between control HD (C-HD) and E-HD after 8 weeks. Fatigue was evaluated using a numerical rating scale (NRS) during the 8-week course.

Results

In C-HD, an increase in serum MPO accompanied increases in both oxidative products (MDA-a) and anti-oxidant molecules (TRX). In E-HD, although increases in MPO were accentuated during HD, changes in MDA-a and TRX were ameliorated as compared with C-HD. In patients who showed HD-related fatigue (47%) during C-HD, change in MDA-a by HD was a risk factor for the presence of fatigue. During the 8 weeks of observation on E-HD, those patients displayed significant decreases in fatigue scores.

Conclusion

E-HD ameliorates oxidative stress and supports anti-oxidation during HD, suggesting improved bio-compatibility of the HD system. E-HD may benefit patients with HD-related fatigue, but the mechanisms underlying changes to oxidative stress have yet to be clarified.

Korean Version of the Swedish Occupational Fatigue Inventory among Construction Workers: Cultural Adaptation and Psychometric Evaluation

The Swedish Occupational Fatigue Inventory (SOFI) has been tested in different languages and populations; thus, there is a need for a culturally adapted Korean version. We evaluated the psychometric properties of a Korean version of the SOFI among construction workers. The SOFI was translated into Korean and reviewed through a back-translation process involving standardized scaling procedures. Its reliability and validity were evaluated with a sample of 193 construction workers using internal consistency, item–subscale correlations, test–retest reliability, and content, construct, and concurrent validity. The Cronbach’s alpha coefficients of the total scale and each subscale were satisfactory. Item–subscale correlations and test–retest reliability were both at acceptable levels. Confirmatory factor analyses revealed that the five-factor model had acceptable model fits corresponding to the structure of the original instrument. However, some modifications were made to improve in the new context from model fit (such as χ²(95) = 113.905 (p = 0.091), CFI = 0.994, and RMSEA = 0.033, as well as the lowest AIC = 383.905). Correlation analysis showed a significant relationship of SOFI with other fatigue measures in terms of total and subscale scores. Occupational fatigue is one of the important risk factors associated with workers’ health and safety at work. The new translated instrument is a reliable and valid tool for assessing fatigue among Korean construction workers. However, this instrument should be tested extensively in other working populations to devise specific interventions concerning fatigue reduction.

Fatigue characteristics on dialysis and non-dialysis days in patients with chronic kidney failure on maintenance hemodialysis

BACKGROUND

Fatigue is prevalent in hemodialysis patients who for survival follow a strict dialysis treatment regimen - dialysis and non-dialysis days. As a result, the daily activities, symptom burden, and clinical outcomes of hemodialysis patients vary significantly between dialysis and non-dialysis days. Fatigue is one of the most reported debilitating symptoms by hemodialysis patients with profound negative impact on their quality of life. Prior studies assessed fatigue during the preceding 7 or 30 days and did not discriminate fatigue characteristics between dialysis and non-dialysis days. We aimed to characterize and compare fatigue severity and fatigue interference with daily activities between dialysis and non-dialysis days.

METHODS

Hemodialysis patients self-reported fatigue on consecutive dialysis and non-dialysis days using the 9-item Brief Fatigue Inventory. The differences in fatigue characteristics between dialysis and non-dialysis days were analyzed using one-way ANCOVA.

RESULTS

Global fatigue burden was worse on a dialysis day compared to a non-dialysis day (P for all < 0.001). Age and education were associated with fatigue, but hemodialysis-related variables were not. A significant inverse association of physical activity with fatigue severity observed on non-dialysis day; there was also a negative association between the normalized protein catabolic rate and fatigue severity on both dialysis and non-dialysis days. The positive association of depression with fatigue severity and fatigue interference were consistent on both dialysis and non-dialysis days. None of these factors, however, explained differences in fatigue characteristics between dialysis and non-dialysis days.

CONCLUSIONS

Fatigue, measured in severity and interference, was more pronounced on a dialysis day relative to a non-dialysis day. These differences were not explained by age, sex, education, hemodialysis-related variables, habitual exercise, nutritional status, and or depression. The quantitative measures of fatigue characteristics may facilitate future interventional trials design and better fatigue management for hemodialysis patients.

Prevalence and experience of fatigue in survivors of critical illness: a mixed-methods systematic review

We conducted a mixed methods systematic review to investigate the prevalence, experience and management of fatigue in survivors of critical illness. We identified 76 studies investigating fatigue or vitality in adults discharged from an intensive care unit and split the extracted data into three datasets: vitality scores from the Short Form Health Survey-36 (n = 54); other quantitative data (n = 19); and qualitative data (n = 9). We assessed methodological quality using critical appraisal skills programme tools. We adopted a segregated approach to mixed-methods synthesis. In a final step, we attributed combined results to one of four qualitative themes: prevalence and severity; contributing factors; impacts on quality of life; and assessment and management. Prevalence of fatigue ranged from 13.8 to 80.9%. Short Form Health Survey-36 vitality scores were commonly used as a marker of fatigue. Vitality scores reached a nadir approximately one month following ICU discharge (mean (SD) 56.44 (32.30); 95%CI 52.92-59.97). They improved over time but seldom reached reference population scores. Associated biological, disease-related and psychological factors included age, poor pre-morbid status, sleep and psychological disturbance. Qualitative data highlight the profound negative impact of fatigue on survivors' quality of life. Survivors seldom had any information provided on the potential impact of fatigue. No fatigue assessment tools specific to critical illness or evidence-based interventions were reported. Fatigue is highly prevalent in survivors of critical illness, and negatively impacts recovery. Further research on developing fatigue assessment tools specifically for critically ill patients and evaluating the impact of pharmacological and non-pharmacology interventions is needed.

The Effect of Aromatherapy Massage With Lavender and Citrus Aurantium Essential Oil on Quality of Life of Patients on Chronic Hemodialysis: A Parallel Randomized Clinical Trial Study

CONTEXT

Poor quality of life is a major problem in hemodialysis patients.

OBJECTIVES

This study was conducted to assess the effect of aromatherapy massage on hemodialysis patients' quality of life.

METHODS

In this parallel randomized clinical trial study, 105 hemodialysis patients who meet the inclusion criteria were assessed and assigned into intervention and control groups using block randomization. Participants in the intervention groups received aromatherapy massage with Lavender essential oil or Citrus Aurantium essential oil for four weeks (three times per week). For the control group, only foot massage was performed. The level of quality of life was measured by the 36-Item Short-Form Health Survey questionnaire (SF-36) before and after the intervention. Data analysis was performed using descriptive and inferential statistics (analysis of variance, chi-square, and Fisher's exact tests).

RESULTS

There was a significant difference between the mean score of quality of life in the Lavender essential oil group and Citrus Aurantium essential oil group with the control group after intervention. However, there was no significant difference between the mean score of quality of life in the Lavender essential oil group and Citrus Aurantium essential oil group after the intervention.

CONCLUSIONS

In this study, both aromatherapy massages have positive effects on the quality of life of hemodialysis patients. Therefore, nurses are advised to use these aromatherapy massages to improve the quality of life of hemodialysis patients.

Validation of a Core Patient-Reported Outcome Measure for Fatigue in Patients Receiving Hemodialysis: The SONG-HD Fatigue Instrument

BACKGROUND AND OBJECTIVES

Fatigue is a very common and debilitating symptom and identified by patients as a critically important core outcome to be included in all trials involving patients receiving hemodialysis. A valid, standardized measure for fatigue is needed to yield meaningful and relevant evidence about this outcome. This study validated a core patient-reported outcome measure for fatigue in hemodialysis.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

A longitudinal cohort study was conducted to assess the validity and reliability of a new fatigue measure (Standardized Outcomes in Nephrology-Hemodialysis Fatigue [SONG-HD Fatigue]). Eligible and consenting patients completed the measure at three time points: baseline, a week later, and 12 days following the second time point. Cronbach α and intraclass correlation coefficient were calculated to assess internal consistency, and Spearman rho was used to assess convergent validity. Confirmatory factor analysis was also conducted. Hemodialysis units in the United Kingdom, Australia, and Romania participated in this study. Adult patients aged 18 years and over who were English speaking and receiving maintenance hemodialysis were eligible to participate. Standardized Outcomes in Nephrology-Hemodialysis, the Visual Analog Scale for fatigue, the 12-Item Short Form Survey, and Functional Assessment of Chronic Illness Therapy-Fatigue were used.

RESULTS

In total, 485 participants completed the study across the United Kingdom, Australia, and Romania. Psychometric assessment demonstrated that Standardized Outcomes in Nephrology-Hemodialysis is internally consistent (Cronbach α =0.81-0.86) and stable over a 1-week period (intraclass correlation coefficient =0.68-0.74). The measure demonstrated convergence with Functional Assessment of Chronic Illness Therapy-Fatigue and had moderate correlations with other measures that assessed related but not the same concept (the 12-Item Short Form Survey and the Visual Analog Scale). Confirmatory factor analysis supported the one-factor model.

CONCLUSIONS

SONG-HD Fatigue seems to be a reliable and valid measure to be used in trials involving patients receiving hemodialysis.

Toward Patient-Centered Innovation: A Conceptual Framework for Patient-Reported Outcome Measures for Transformative Kidney Replacement Devices

Individuals with dialysis-dependent kidney failure experience considerable disease- and treatment-related decline in functional status and overall well-being. Despite these experiences, there have been few substantive technological advances in KRT in decades. As such, new federal initiatives seek to accelerate innovation. Historically, integration of patient perspectives into KRT product development has been limited. However, the US Food and Drug Administration recognizes the importance of incorporating patient perspectives into the total product life cycle (i.e., from product conception to postmarket surveillance) and encourages the consideration of patient-reported outcomes in regulatory-focused clinical trials when appropriate. Recognizing the significance of identifying patient-reported outcome measures (PROMs) that capture contemporary patient priorities, the Kidney Health Initiative, a public-private partnership between the American Society of Nephrology and US Food and Drug Administration, convened a workgroup to (1) develop a conceptual framework for a health-related quality of life PROM; (2) identify and map existing PROMs to the conceptual framework, prioritizing them on the basis of their supporting evidence for use in the regulatory environment; and (3) describe next steps for identifying PROMs for use in regulatory clinical trials of transformative KRT devices. This paper summarizes the proposed health-related quality-of-life PROM conceptual framework, maps and prioritizes PROMs, and identifies gaps and future needs to advance the development of rigorous, meaningful PROMS for use in clinical trials of transformative KRT devices.

Impaired kidney function is associated with lower quality of life among community-dwelling older adults : The screening for CKD among older people across Europe (SCOPE) study

Background

Quality of life (QoL) refers to the physical, psychological, social and medical aspects of life that are influenced by health status and function. The purpose of this study was to measure the self-perceived health status among the elderly population across Europe in different stages of Chronic Kidney Disease (CKD).

Methods

Our series consisted of 2255 community-dwelling older adults enrolled in the Screening for Chronic Kidney Disease (CKD) among Older People across Europe (SCOPE) study. All patients underwent a comprehensive geriatric assessment (CGA), including included demographics, clinical and physical assessment, number of medications taken, family arrangement, Geriatric Depression Scale (GDS), Cumulative Illness Rating Scale, History of falls, Lower urinary tract symptoms, and Short Physical Performance Battery (SPPB). Estimated glomerular filtration rate (eGFR) was calculated by Berlin Initiative Study (BIS) equation. Quality of life was assessed by Euro Qol questionnaire (Euro-Qol 5D) and EQ-Visual Analogue Scale (EQ-VAS). The association between CKD (eGFR < 60, < 45 ml or < 30 ml/min/1.73m²) and low EQoL-VAS was investigated by multivariable logistic regression models.

Results

CKD was found to be significantly associated with low EQoL-VAS in crude analysis (OR = 1.47, 95%CI = 1.16–1.85 for eGFR< 60; OR = 1.38, 95%CI = 1.08–1.77 for eGFR< 45; OR = 1.57, 95%CI = 1.01–2.44). Such association was no longer significant only when adjusting for SPPB (OR = 1.20, 95%CI = 0.93–1.56 for eGFR< 60; OR = 0.87, 95%CI = 0.64–1.18 for eGFR< 45; OR = 0.84, 95%CI = 0.50–1.42), CIRS and polypharmacy (OR = 1.16, 95%CI = 0.90–1.50 for eGFR< 60; OR = 0.86, 95%CI = 0.64–1.16 for eGFR< 45; OR = 1.11, 95%CI = 0.69–1.80) or diabetes, hypertension and chronic obstructive pulmonary disease (OR = 1.28, 95%CI = 0.99–1.64 for eGFR< 60; OR = 1.16, 95%CI = 0.88–1.52 for eGFR< 45; OR = 1.47, 95%CI = 0.92–2.34). The association between CKD and low EQoL-VAS was confirmed in all remaining multivariable models.

Conclusions

CKD may significantly affect QoL in community-dwelling older adults. Physical performance, polypharmacy, diabetes, hypertension and COPD may affect such association, which suggests that the impact of CKD on QoL is likely multifactorial and partly mediated by co-occurrent conditions/risk factors.
