[PMID: 38938194 PMCID: PMC11216259 DOI: 10.1080/0886022x.2024.2370439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2024] [Accepted: 06/14/2024] [Indexed: 06/29/2024] Open
Abstract
BACKGROUND Chronic kidney disease (CKD) poses a significant public health challenge globally while impacting patients' physical function and quality of life. Addressing the issues of physical inactivity and pain management is essential during treatment to improve health-related quality of life. The present study investigated the effect of an aerobic training program with core stabilization exercises for hemodialysis (HD) patients on a transplant waiting list and renal transplant (RTx) patients. METHODS A total of 45 patients with CKD were included in the 12-week study: 25 patients receiving HD (12 HD treatment group, 13 HD control group) and 20 patients with RTx (9 RTx treatment group, 11 RTx control group). Functional capacity was measured using the 6-min walk test, pain was measured using the visual analog scale, and health-related quality of life was measured using the Kidney Disease Quality of Life-Short Form 12 questionnaire. Nonparametric statistical tests were performed at a significance level of 0.05. RESULTS Both the HD and RTx treatment groups showed significantly reduced times for the 6-min walking test (p = 0.002 and p = 0.008, respectively), significantly reduced pain severity (p = 0.002 and p = 0.008, respectively), and significantly improved quality of life scores (p = 0.006 and p = 0.041, respectively) by the end of the study compared with control groups. CONCLUSION Based on the results, structured exercise programs could be effective therapies in CKD management. Therefore, health providers should promote their integration into routine care practices to enhance patient outcomes and well-being.

Abstract
BACKGROUND Patients with end-stage kidney disease (ESKD) receiving peritoneal dialysis (PD) or haemodyalisis (PD) appear to be less physically active than healthy persons, a situation that could lead to reductions in quality of life. The aim of the present study was to assess and compare physical activity and health-related quality of life in renal patients on HD and PD programs. METHODS In May 2020, 130 patients (106 HD and 24 PD) were enrolled in a study of chronic dialysis programs. All participants received a questionnaire containing information on demographics, treatment, and co-morbidities. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ) short form, and quality of life was measured using the Kidney Disease Quality of Life-Short Form 12 (KDQOL-SF-12) questionnaire comprising mental (MCS) and physical components (PCS). Non-parametric statistical tests were executed with 0.05 as the level of significance. RESULTS The physical activity of patients treated in both HD and PD programs could be considered as low, without a statistically significant difference between the two modalities. For the quality of life measures, we found a significant (p = .004) difference regarding Physical Component Summary (PCS) scores, with higher PCS scores in patients treated in the PD programme compared to HD. Furthermore, higher physical activity levels were associated with better quality of life parameters in both groups. CONCLUSION This study confirms the importance of physical activity among dialysis patients with ESKD, suggesting that greater activity could be associated with a better quality of life.

Assessing quality of life in solid organ transplant recipients: A systematic review of the development, content, and quality of available condition- and transplant-specific patient-reported outcome measures. Transplant Rev (Orlando) 2024; 38:100836. [PMID: 38359538 DOI: 10.1016/j.trre.2024.100836] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 02/08/2024] [Accepted: 02/11/2024] [Indexed: 02/17/2024]
Abstract
PURPOSE We aimed to identify the condition- and transplant-specific patient-reported outcome measures (PROMs) available to measure quality of life (QoL) in solid organ transplant (SOT) recipients, examine their development and content, and critically appraise the quality of their measurement properties, to inform recommendations for clinical and research use. METHODS We systematically searched MEDLINE, Embase, CINAHL, PsycINFO, Cochrane CENTRAL, and Scopus from inception to 27th January 2023. Search hits were screened for eligibility by two independent reviewers; papers reporting the development and/or validation of condition- and transplant-specific PROMs measuring QoL in adult SOT recipients were considered eligible. We abstracted and synthesised data on PROM characteristics, development (item generation and/or reduction), and content (QoL dimensions). Quality appraisal and synthesis were informed by the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) guidelines, and included methodological and quality assessment of measurement properties, GRADE levels of evidence, feasibility and interpretability. RESULTS We identified 33 papers reporting 26 QoL PROMs validated in SOT recipients (kidney n = 10 PROMs; liver n = 6; lung n = 3; heart n = 2; pancreas n = 1; multiple organs n = 4). Patient discussions (n = 17 PROMs) and factor analysis (n = 11) were the most common item generation and reduction techniques used, respectively. All PROMs measured ≥3 of nine QoL dimensions (all measured emotional functioning); KDQoL-SF and NIDDK-QA measured all nine. Methodological quality was variable; no PROM had low evidence or better for all measurement properties. All PROMs were COSMIN recommendation category 'B', primarily because none had sufficient content validity. CONCLUSIONS There are many condition- and transplant-specific QoL PROMs validated in SOT recipients, particularly kidney. These findings can help inform PROM selection for clinicians and researchers. However, caution is required when adopting measures, due to the substantial heterogeneity in development, content, and quality. Each PROM has potential but requires further research to be recommendable. Greater consideration of patient and professional involvement in PROM development in this setting is needed to ensure sufficient content validity.

Abstract
Cognitive impairment is common in patients with end-stage renal disease (ESRD) and is associated with compromised quality of life and functional capacity, as well as worse clinical outcomes. Most previous research and reviews in this area were focused on objective cognitive impairment, whereas patients' subjective cognitive complaints (SCCs) have been less well-understood. This systematic review aimed to provide a broad overview of what is known about SCCs in adult ESRD patients. Electronic databases were searched from inception to January 2022, which identified 221 relevant studies. SCCs appear to be highly prevalent in dialysis patients and less so in those who received kidney transplantation. A random-effects meta-analysis also shows that haemodialysis patients reported significantly more SCCs than peritoneal dialysis patients (standardised mean difference -0.20, 95% confidence interval -0.38 to -0.03). Synthesis of longitudinal studies suggests that SCCs remain stable on maintenance dialysis treatment but may reduce upon receipt of kidney transplant. Furthermore, SCCs in ESRD patients have been consistently associated with hospitalisation, depression, anxiety, fatigue, and poorer quality of life. There is limited data supporting a strong relation between objective and subjective cognition but preliminary evidence suggests that this association may be domain-specific. Methodological limitations and future research directions are discussed.

Abstract
Background The optimal duration of antifrailty interventions and how best to deliver them to patients with chronic kidney disease (CKD) is unknown. The aim of this study was to examine the safety, feasibility and preliminary efficacy of a 4-week supervised exercise intervention on frailty in patients with CKD. Methods We conducted a prospective feasibility study involving patients with ≥stage 3 CKD (1 patient with stage 3 CKD, 7 patients with stage 4 CKD and 17 patients with stage 5 CKD) who were either frail or prefrail according to the physical frailty phenotype and/or had a Short Physical Performance Battery (SPPB) score ≤10. The exercise intervention consisted of two supervised outpatient sessions per week for 4 weeks (eight total sessions). Frailty and other study measures were assessed at baseline and after 4 weeks of exercise. Results Of the 34 participants who completed the baseline assessment and were included in the analyses, 25 (73.5%) completed the 4-week assessment. Overall, 64.0% of patients were on dialysis and 64.0% had diabetes mellitus. After 4 weeks of exercise, frailty prevalence, total SPPB scores and energy/fatigue scores improved. No adverse study-related outcomes were reported. Conclusions The 4 weeks of supervised exercise was safe, was associated with an excellent completion rate and improved frailty parameters in CKD patients with CKD. This study provides important preliminary data for a future larger prospective randomized study. Clinical Trialgov registration: NCT03535584.

Abstract
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.

Abstract
BACKGROUND Treatment burden refers to the work involved in managing one's health and its impact on well-being and has been associated with nonadherence in patients with chronic illnesses. No kidney transplant (KT)-specific measure of treatment burden exists. The aim of this study was to develop a KT-specific supplement to the Patient Experience with Treatment and Self-Management (PETS), a general measure of treatment burden. METHODS After drafting and pretesting KT-specific survey items, we conducted a cross-sectional survey study involving KT recipients from Mayo Clinic in Minnesota, Arizona, and Florida. Exploratory factor analysis (EFA) was used to identify domains for scaling the KT-specific supplement. Construct and known-groups validity were determined. RESULTS Survey respondents (n = 167) had a mean age of 61 years (range 22-86) and received a KT on average 4.0 years ago. Three KT-specific scales were identified (transplant function, self-management, adverse effects). Higher scores on the KT-specific scales were correlated with higher PETS treatment burden, worse physical and mental health, and lower self-efficacy (p < 0.0001). Patients taking more medications reported higher transplant self-management burden. CONCLUSIONS We developed a KT-specific supplement to the PETS general measure of treatment burden. Scores may help providers identify recipients at risk for nonadherence.

Abstract
Rationale & Objective Assessing the optimal therapy for older patients (aged ≥65 years) with end-stage kidney disease requires knowledge of longevity and health-related quality of life (HRQoL) outcomes. Kidney transplantation prolongs survival but its long-term impact on HRQoL in older recipients is not well defined. We aimed to prospectively evaluate HRQoL changes from enlisting until 3 years posttransplantation and examine pretransplantation predictors of posttransplantation outcomes. Study Design Prospective cohort study. Setting & Participants Patients 65 years and older enlisted at the Norwegian National Transplant Center between January 2013 and November 2016. Predictors Kidney transplantation, dialysis vintage, and pretransplantation comorbidity assessed using the Liu Comorbidity Index. Outcomes HRQoL, assessed using the Kidney Disease Quality of Life Short Form, version 1.3. Analytical Approach HRQoL scores obtained at 3 years posttransplantation were compared with those obtained pretransplantation and after 1 year using a paired-sample t test. Multivariable linear mixed-effect models were used to identify possible predictors of HRQoL changes over time. Results Among 289 patients included, 220 (mean age, 71.5 years) had undergone transplantation and 136 had completed the 3-year HRQoL follow-up by October 2020. Posttransplant HRQoL, both generic and kidney specific, substantially improved and the benefit persisted for 3 years. For wait-listed candidates remaining on dialysis, HRQoL gradually deteriorated, and recipients who died within 3 years posttransplantation experienced no improvement during the first year. Moderately elevated pretransplantation comorbidity scores and prolonged dialysis vintage independently predicted poor HRQoL outcomes posttransplantation. Recipients receiving dialysis for 1 year or longer with pretransplantation comorbidity scores ≥ 7 experienced a marked and sustained physical deterioration after transplantation. Limitations Homogenous and highly selected population. Conclusions Transplantation is associated with a sustained HRQoL improvement and should be the preferred treatment for selected older patients. The value of a pretransplant comorbidity score to predict posttransplantation outcomes warrants further evaluation and may improve the selection process.

Better health-related quality of life in kidney transplant patients compared to chronic kidney disease patients with similar renal function. PLoS One 2021; 16:e0257981.

Abstract
Renal functional deterioration is associated with physical and mental burdens for kidney transplant (KT) and chronic kidney disease (CKD) patients. However, the change in health-related quality of life (HRQOL) over time in KT patients compared to that of native CKD patients has not been evaluated. We addressed this issue using KT patients registered in the KNOW-KT cohort study and patients at CKD stage 1–3 registered in the KNOW-CKD cohort study. HRQOL scores were assessed using the Kidney Disease Quality of Life Short Form at baseline, 2-, and 4-years follow-up in 842 KT patients and at baseline and 5-year follow-up in 1,355 CKD patients. SF-36 scores declined at the 4-year follow-up, whereas CKD-targeted scores showed no change in the KT group. In contrast, CKD-targeted scores as well as SF-36 scores were decreased at the 5-year follow-up in CKD patients. When prognostic factors were analyzed for longitudinal HRQOL data over time, renal functions, diabetes, cardiovascular and cerebrovascular diseases, hemoglobin level, marital status, income, employment, and health care were significant prognostic factors. Furthermore, KT was an independent prognostic factor for better HRQOL. These results highlight that KT can offer a better HRQOL than that of CKD patients, even when renal function is similar.

Yuksel E, Aydin E. The relationship between serum vitamin D levels and health-related quality of life in peritoneal dialysis patients. Int Urol Nephrol 2021; 54:927-936. [PMID: 34292490 DOI: 10.1007/s11255-021-02951-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Accepted: 07/07/2021] [Indexed: 12/12/2022]
Abstract
INTRODUCTION We aimed to investigate the relationship between Vitamin D level and quality of life in patients undergoing peritoneal dialysis as renal replacement therapy. METHODS 50 peritoneal dialysis patients aged between 18 and 73 years were included in this study. KDQOL-36 questionnaire was applied to rate the quality of life of the patients. This questionnaire consisted of 36 questions divided into five subscales. The patients were divided into two groups according to serum vitamin D levels. Patients with a serum 25(OH) D level < 20 ng/mL were identified as vitamin D deficiency group and those with a serum 25(OH)D level ≥ 20 ng/mL were identified as normal vitamin D group. RESULTS The patients had a mean age of 41.16 ± 16.05 years, 56% of them were females. The mean 25(OH) D levels of patients with 25 (OH) D levels < 20 ng/mL and those with ≥ 20 ng/mL were 10.50 ± 4.62 ng/mL and 25.55 ± 4.11 ng/mL, respectively. We found that all subscales of KDQOL-36 were lower with statistically significance in the group with Vitamin D (Vit-D) deficiency. Hemoglobin level was detected as independent risk factor for Symptom and problem list subscales and SF-12 physical component summary subscale (PCS) (P = 0.029, P = 0.047). Vit-D deficiency was detected as independent risk factors for kidney disease burden subscale and PCS (P = 0.035, P = 0.019). Hypertension was detected as independent risk factor for kidney disease burden subscale (P = 0.015). CONCLUSION Our study is the first to investigate the relationship between serum Vit-D level and quality of life by KDQOL-36 scale in peritoneal dialysis patients. We revealed that patients with low Vit-D levels had worse quality of life in all subscales.

Evaluation of PROMIS Preference Scoring System (PROPr) in Patients Undergoing Hemodialysis or Kidney Transplant. Clin J Am Soc Nephrol 2021; 16:1328-1336. [PMID: 34272256 PMCID: PMC8729576 DOI: 10.2215/cjn.01880221] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2021] [Accepted: 06/22/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND AND OBJECTIVES A preference-based health utility score (PROPr) can be calculated using Patient-Reported Outcomes Measurement Information System domain scores. We assessed the construct validity of PROPr among patients treated with KRT (hemodialysis or kidney transplant). DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We performed a secondary analysis of data collected in multicenter, cross-sectional studies of adults treated with KRT, recruited between April 2016 to March 2020 in Toronto, Canada. All participants provided informed consent. The outcome was the PROPr score. Coadministered outcome variables included the Short-Form Six-Domain (SF-6D) and EuroQol Five-Domain Five-Level (EQ-5D-5L) scores. Socioeconomic and clinical variables included age, sex, diabetes, eGFR, serum albumin, hemoglobin, KRT, and Charlson Comorbidity Index. Construct validity was assessed through correlations between PROPr and SF-6D or EQ-5D-5L, and associations between PROPr and other exposure variables. Health-condition impact estimates (coefficients for health conditions compared with a referent category, e.g., dialysis versus kidney transplant) were calculated using multivariable linear regression. RESULTS The mean (SD) age of the 524 participants was 57 (17) years, 58% were male, and 45% were White. Median (interquartile range) score was 0.39 (0.24-0.58) for PROPr, 0.69 (0.58-0.86) for SF-6D, and 0.85 (0.70-0.91) for EQ-5D-5L. Large correlations were observed between PROPr versus SF-6D (0.79; 95% confidence interval [95% CI], 0.76 to 0.82) and EQ-5D-5L (0.71; 95% CI, 0.66 to 0.75). Both PROPr and the other utility indices demonstrated health-condition impact in the expected direction. For example, the estimate for PROPr was -0.17 (95% CI, -0.13 to -0.21) for dialysis (versus kidney transplant), -0.05 (95% CI, -0.11 to 0.01; P=0.08) for kidney transplant recipients with an eGFR of <45 versus ≥45 ml/min per 1.73 m2, and -0.28 (95% CI, -0.22 to -0.33) for moderate/severe versus no/mild depressive symptoms. CONCLUSIONS Our results support the validity of PROPr among patients treated with KRT.

Abstract
Kidney transplant recipients are at risk of developing important adverse effects after transplantation. The objective of this study was to investigate the effects of a 10-week supervised resistance exercise-based intervention in kidney transplant recipients. Sixteen participants were randomized to a training (n = 8, 49.7 ± 9.6 years) or control group (n = 8, 48.6 ± 10.6 years). The primary endpoint was health-related quality of life evaluated through the Kidney Disease Quality of Life-Short Form (KDQOL-SF), which includes the 36-Item Short Form Survey (SF-36), and secondary endpoints included physical performance (6-minute walk distance [6-MWD], 60-second sit to stand test [60-STS], 8-foot up and go test, and handgrip and lower limb muscle strength), muscle mass, and biochemical parameters. Endpoints were assessed at baseline and after 10 weeks. Resistance exercise significantly increased (P < .05) some SF-36 domains and tended to induce improvements in one specific KDQOL-SF domain (P = .050). Further, exercise benefits were observed for 6-MWD (9% and 1% for the training and control groups, respectively; P < .001), handgrip strength (7% and -1%; P = .005), 60-STS repetitions (18% and -7%; P < .001), and 8-foot up and go test performance time (-5% and 6%; P = .010). No between-group differences (P > .05) were found for the remaining endpoints. There were no adverse events, musculoskeletal injuries, hypoglycemic episodes, cardiovascular events, or hospitalizations related to the intervention. In conclusion, 10 weeks of supervised resistance training is enough to improve quality of life and physical performance without side effects such as musculoskeletal injuries, hypoglycemic episodes, cardiovascular events, or hospitalizations related to the intervention in kidney transplant recipients.

Abstract
BACKGROUND Frailty and decreased functional status are risk factors for adverse kidney transplant (KT) outcomes. Our objective was to examine the efficacy of an exercise intervention on frailty and decreased functional status in a cohort of patients with advanced chronic kidney disease (CKD). METHODS We conducted a prospective study involving 21 adults with ≥stage 4 CKD who were (a) frail or pre-frail by Fried phenotype and/or (b) had lower extremity impairment [short physical performance battery score ≤10]. The intervention consisted of two supervised outpatient exercise sessions per week for 8 weeks. RESULTS Among our cohort, median participant age was 62 years (interquartile range, 53-67) and 85.7% had been evaluated for KT. Following the study, participants reported satisfaction with the intervention and multiple frailty parameters improved significantly, including fatigue, physical activity, walking time, and grip strength. Lower extremity impairment also improved (90.5%-61.9%, P = .03). No study-related adverse events occurred. CONCLUSIONS Preliminary data from this study suggest that a supervised, outpatient exercise intervention is safe, acceptable, feasible, and associated with improved frailty parameters, and lower extremity function, in patients with advanced CKD. Further studies are needed to confirm these findings and determine whether this prehabilitation strategy improves KT outcomes.

Abstract
OBJECTIVE to analyze the quality of life of kidney transplant receivers in the State of Amazonas. METHOD a cross-sectional, descriptive study, performed with 222 individuals after renal transplantation registered in a private clinic and in a health public ambulatory. Data collection took place through structured interviews where the quality of life was measured by the Kidney Disease Quality of Life - Short Form. Descriptive statistics were used for data analysis. RESULTS the quality of life scores found ranged from 36.5 to 83.1. The quality of life domains, specifics of renal disease, have proved to be superior to generic ones. The most compromised were work situation; sleep; physical function and emotional function, with scores of 36.5; 53.7; 52.4; 55.1, respectively, and correlated moderately and significantly with each other. CONCLUSION the majority (63.2%) of the quality of life domains obtained high scores and the specific component of renal disease had higher scores than the generic component.

Abstract
We assessed the validity of the Edmonton Symptom Assessment System (ESAS-r) in kidney transplant recipients (KTR). A cross-sectional sample of 252 KTR was recruited. Individual ESAS-r symptom scores and symptom domain scores were evaluated. Internal consistency, convergent validity, and construct validity were assessed with Cronbach's α, Spearman's rank correlations, and a priori-defined risk group comparisons. Mean (SD) age was 51 (16), 58% were male, and 58% Caucasian. ESAS-r Physical, Emotional, and Global Symptom Scores demonstrated good internal consistency (α > 0.8 for all). ESAS-r Physical and Global Symptom Scores strongly correlated with PHQ-9 scores (0.72, 95% CI: 0.64-0.78 and 0.74, 95% CI: 0.67-0.80). For a priori-defined risk groups, individual ESAS-r symptom score differed between groups with lower versus higher eGFR [pain: 1 (0-3) vs. 0 (0-2), delta = 0.18; tiredness: 3 (1-5) vs. 1.5 (0-4), delta = 0.21] and lower versus higher hemoglobin [tiredness: 3 (1-6) vs. 2 (0-4), delta = 0.27]. ESAS-r Global and Physical Symptom Scores differed between groups with lower versus higher hemoglobin [13 (6-29) vs. 6.5 (0-18.5), delta = 0.3, and 9 (2-19) vs. 4 (0-13), delta = 0.24] and lower versus higher eGFR [11 (4-20) vs. 6.5 (2-13), delta = 0.21, and 7 (2-16) vs. 3 (0-9), delta = 0.26]. These data support reliability and construct validity of ESAS-r in KTR. Future studies should explore its clinical utility for symptom assessment among KTR.

Abstract
The impact of health-related quality of life (HRQOL) on outcomes remains unclear in chronic kidney disease (CKD) patients despite its importance in socioeconomic aspects and individual health. We aim to identify the relationship between HRQOL and progression of CKD in pre-dialysis patients. A total 1622 patients with CKD were analyzed in the KoreaN cohort Study for Outcomes in patients With Chronic Kidney Disease, a prospective cohort study. CKD progression was defined as one or more of the following: initiation of dialysis or transplantation, a two-fold increase in baseline serum creatinine levels, or a 50% decline in the estimated glomerular filtration rate during the follow-up period. The group with CKD progression had lower scores of HRQOL than the group without CKD progression. A fully adjusted Cox proportional hazard ratio model showed that each low baseline physical and mental component summary score was associated with a higher risk of CKD progression. In Kaplan-Meier survival analysis using propensity score matched data, only low physical component summary scores showed statistical significance with CKD progression. Our study highlights low physical component summary score for an important prognostic factor of CKD progression. Risk-modification interventions for high-risk patients may provide benefits to individuals.

Abstract
For many patients with end-stage kidney disease, transplantation improves survival and quality of life compared with dialysis. However, complications and side effects in kidney transplant recipients can limit their ability to participate in activities of daily living including work, study, and recreational activities. The aim of this study was to identify the characteristics, content, and psychometric properties of the outcome measures used to assess life participation in kidney transplant recipients. We searched MEDLINE, Embase, PsycINFO, and CINAHL from inception to July 2018 for all studies that reported life participation in kidney transplant recipients. Two authors identified instruments measuring life participation and reviewed for characteristics. In total, 230 studies were included: 19 (8%) randomized trials, 17 (7%) nonrandomized trials, and 194 (85%) observational studies. Across these studies, we identified 29 different measures that were used to assess life participation. Twelve (41%) measures specifically assessed aspects of life participation (eg, disability assessment, daily activities of living), while 17 (59%) assessed other constructs (eg, quality of life) that included questions on life participation. Validation data to support the use of these measures in kidney transplant recipients were available for only 7 measures. A wide range of measures have been used to assess life participation in kidney transplant recipients, but validation data supporting the use of these measures in this population are sparse. A content relevant and validated measure to improve the consistency and accuracy of measuring life participation in research may inform strategies for transplant recipients to be better able to engage in their life activities.

Abstract
BACKGROUND Health-related quality of life (HRQOL) reflects a patient's disease burden, treatment effectiveness, and health status and is summarized by physical, mental, and kidney disease-specific scales among end-stage renal disease patients. Although on average HRQOL improves postkidney transplant (KT), the degree of change depends on the ability of the patient to withstand the stressor of dialysis versus the ability to tolerate the intense physiologic changes of KT. Frail KT recipients may be extra vulnerable to either of these stressors, thus affecting change in HRQOL after KT. METHODS We ascertained frailty, as well as physical, mental, and kidney disease-specific HRQOL in a multicenter prospective cohort of 443 KT recipients (May 2014 to May 2017) using Kidney Disease Quality of Life Instrument Short Form. We quantified the short-term (3 months) rate of post-KT HRQOL change by frailty status using adjusted mixed-effects linear regression models. RESULTS Mean HRQOL scores at KT were 43.3 (SD, 9.6) for physical, 52.8 (SD, 8.9) for mental, and 72.6 (SD, 12.8) for kidney disease-specific HRQOL; frail recipients had worse physical (P < 0.001) and kidney disease-specific HRQOL (P = 0.001), but similar mental HRQOL (P = 0.43). Frail recipients experienced significantly greater rates of improvement in physical HRQOL (frail, 1.35 points/month; 95% confidence interval [CI], 0.65-2.05; nonfrail, 0.34 points/month; 95% CI, -0.17-0.85; P = 0.02) and kidney disease-specific HRQOL (frail, 3.75 points/month; 95% CI, 2.89-4.60; nonfrail, 2.41 points/month; 95% CI, 1.78-3.04; P = 0.01), but no difference in mental HRQOL (frail, 0.54 points/month; 95% CI, -0.17-1.25; nonfrail, 0.46 points/month; 95% CI, -0.06-0.98; P = 0.85) post-KT. CONCLUSIONS Despite decreased physiologic reserve, frail recipients experience improvement in post-KT physical and kidney disease-specific HRQOL better than nonfrail recipients.

Abstract
Background: The quality of life of patients undergoing hemodialysis is lower; to improve their living conditions, patients need further training. This study conducted to compare the effectiveness of two methods of text messaging and face to face education on knowledge and quality of life of patients under hemodialysis.
Methods: Undergoing in a clinical trial study, 60 patients undergoing hemodialysis in Sina-teaching hospital of Tabriz, Iran were selected by convenience sampling and randomly allocated into three groups: two intervention groups: text massaging (P=20), face to face group (n=20) and one control group (n=20). Their knowledge and quality of life were assessed and compared by Chronic Hemodialysis Knowledge Survey (CHeKS) and Kidney Disease Quality of Life-short form (KDQOL-SF) questionnaires. Data were analyzed by SPSS version 13.
Results: After intervention, the knowledge of text messaging and face to face groups were significantly more than the control group, but the quality of life scores after intervention had not any significant difference among the three groups. Intra-group comparisons showed that quality of life in face to face group have been significantly increased.
Conclusion: Text messaging and face to face teaching were effective on improving knowledge of patients undergoing hemodialysis. However, the effectiveness of these methods on quality of life needs further evaluations in different setting for longer times in hemodialysis patients.

Abstract
BACKGROUND Kidney transplant recipients are frequently treated for other medical conditions and experience polypharmacy. The aim of our study was to evaluate quality of life in relation to medicines' burden in these patients. METHODS We studied 136 unselected patients with mean post-transplant time of 7.2 ± 4.6 years. Quality of life was evaluated using a validated Polish version of the Kidney Disease Quality of Life-Short Form questionnaire. Data concerning the type (generic name) and number of currently prescribed medications were collected by interview survey. The participants were divided into 3 groups: group 1, patients with a maximum of 4 different medications (n = 37); group 2, patients with 4 to 9 medications (n = 76); and group 3, patients receiving at least 10 different medications (n = 23). RESULTS The number of medicines taken regularly ranged from 2 to 16. Patients with ≥10 drugs had the highest body mass index and lowest estimated glomerular filtration rate. Patients treated with ≥10 drugs, compared to patients from the 2 other groups, had presented lower subscales results concerning the physical functioning (65.9 vs 84.5 in group 1 and 83.4 in group 2, P < .001 for both comparisons), pain (57.2 vs 82.7 and 76.5, respectively, P < .001 for both), social function (66.8 vs 82.1 and 80.4, respectively, P = .04 for both), and energy/fatigue (54.8 vs 67.7, P = .03 and 65.4, P < .05). Multivariate regression analysis revealed that the number of drugs independently influenced physical functioning, pain, and social function subscales. CONCLUSIONS Polypharmacy is associated with lower quality of life in patients after successful kidney transplantation. The negative impact of polypharmacy is particularly seen regarding physical functioning and pain severity.

Abstract
Background We aimed to evaluate changes in health-related quality of life (HRQoL) in patients 65 years or older from time of kidney transplantation (KTx) until 1 year postengraftment. Methods A single-center prospective study was conducted. HRQoL was measured pre-KTx and at 2, 6, and 12 months postengraftment using self-reported Kidney Disease and Quality of Life short-form version 1.3. Intraindividual scores before and after KTx were evaluated. Liu Comorbidity Index was registered at enlisting. short-form-36 scores were additionally compared with scores from an age-matched population. Results From January 1, 2013, until November 30, 2016, a total of 289 waitlisted patients were included. By September 1, 2017, 134 had reached 1 year postengraftment, and valid questionnaires were available in 120 (90%) patients. Mean age at KTx was 71.6 years (±4.3 years), 71% were male. Living donor was used in 21%, and preemptive KTx was performed in 30% of the recipients. Median waiting time for KTx from deceased donor was 16 months (range, 0.6-50.5 months). A total of 79 (66%) recipients had a Liu Comorbidity Index score of 3 or less. All HRQoL scores except the domain social function improved at 2 months postengraftment and remained stable or continued to improve at 1 year. HRQoL scores 12 months postengraftment were similar to those described in an age-matched general population except for the domain social function which remained at a significantly lower level. Time in dialysis was the most important variable associated with impaired HRQoL postengraftment. Conclusions HRQoL scores showed clinically significant improvement in older KTx recipients 1 year posttransplant.

Abstract
BACKGROUND Surveys using traditional measures of nutritional status indicate that muscle wasting is common among persons with end-stage kidney disease (ESKD). Up to 75% of adults undergoing maintenance dialysis show some evidence of muscle wasting. ESKD is associated with an increase in inflammatory cytokines and can result in cachexia, with the loss of muscle and fat stores. At present, only limited data are available on the classification of wasting experienced by persons with ESKD. Individuals with ESKD often exhibit symptoms of anorexia, loss of lean muscle mass and altered energy expenditure. These symptoms are consistent with the syndrome of cachexia observed in other chronic diseases, such as cancer, heart failure, and acquired immune deficiency syndrome. While definitions of cachexia have been developed for some diseases, such as cardiac failure and cancer, no specific cachexia definition has been established for chronic kidney disease. The importance of developing a definition of cachexia in a population with ESKD is underscored by the negative impact that symptoms of cachexia have on quality of life and the association of cachexia with a substantially increased risk of premature mortality. The aim of this study is to determine the clinical phenotype of cachexia specific to individuals with ESKD. METHODS A longitudinal study which will recruit adult patients with ESKD receiving haemodialysis attending a Regional Nephrology Unit within the United Kingdom. Patients will be followed 2 monthly over 12 months and measurements of weight; lean muscle mass (bioelectrical impedance, mid upper arm muscle circumference and tricep skin fold thickness); muscle strength (hand held dynamometer), fatigue, anorexia and quality of life collected. We will determine if they experience (and to what degree) the known characteristics associated with cachexia. DISCUSSION Cachexia is a debilitating condition associated with an extremely poor outcome. Definitions of cachexia in chronic illnesses are required to reflect specific nuances associated with each disease. These discrete cachexia definitions help with the precision of research and the subsequent clinical interventions to improve outcomes for patients suffering from cachexia. The absence of a definition for cachexia in an ESKD population makes it particularly difficult to study the incidence of cachexia or potential treatments, as there are no standardised inclusion criteria for patients with ESKD who have cachexia. Outcomes from this study will provide much needed data to inform development and testing of potential treatment modalities, aimed at enhancing current clinical practice, policy and education.

Abstract
Chronic kidney disease (CKD) is a complex medical condition that is associated with several comorbidities and requires comprehensive medical management. Given the chronic nature of the condition, its frequent association with psychosocial distress, and its very significant symptom burden, the subjective patient experience is key toward understanding the true impact of CKD on the patients’ life. Patient-reported outcome measures are important tools that can be used to support patient-centered care and patient engagement during the complex management of patients with CKD. The routine collection and use of patient-reported outcomes (PROs) in clinical practice may improve quality of care and outcomes, and may provide useful data to understand the disease from both an individual and a population perspective. Many tools used to measure PROs focus on assessing health-related quality of life, which is significantly impaired among patients with CKD. Health-related quality of life, in addition to being an important outcome itself, is associated with clinical outcomes such as health care use and mortality. In Part 1 of this review, we provide an overview of PROs and implications of their use in the context of CKD. In Part 2, we will review the selection of appropriate measures and the relevant domains of interest for patients with CKD.

Abstract
Background Patient-reported outcome measures (PROMs) can provide valuable information which may assist with the care of patients with chronic kidney disease (CKD). However, given the large number of measures available, it is unclear which PROMs are suitable for use in research or clinical practice. To address this we comprehensively evaluated studies that assessed the measurement properties of PROMs in adults with CKD. Methods Four databases were searched; reference list and citation searching of included studies was also conducted. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was used to appraise the methodological quality of the included studies and to inform a best evidence synthesis for each PROM. Results The search strategy retrieved 3,702 titles/abstracts. After 288 duplicates were removed, 3,414 abstracts were screened and 71 full-text articles were retrieved for further review. Of these, 24 full-text articles were excluded as they did not meet the eligibility criteria. Following reference list and citation searching, 19 articles were retrieved bringing the total number of papers included in the final analysis to 66. There was strong evidence supporting internal consistency and moderate evidence supporting construct validity for the Kidney Disease Quality of Life-36 (KDQOL-36) in pre-dialysis patients. In the dialysis population, the KDQOL-Short Form (KDQOL-SF) had strong evidence for internal consistency and structural validity and moderate evidence for test-retest reliability and construct validity while the KDQOL-36 had moderate evidence of internal consistency, test-retest reliability and construct validity. The End Stage Renal Disease-Symptom Checklist Transplantation Module (ESRD-SCLTM) demonstrated strong evidence for internal consistency and moderate evidence for test-retest reliability, structural and construct validity in renal transplant recipients. Conclusions We suggest considering the KDQOL-36 for use in pre-dialysis patients; the KDQOL-SF or KDQOL-36 for dialysis patients and the ESRD-SCLTM for use in transplant recipients. However, further research is required to evaluate the measurement error, structural validity, responsiveness and patient acceptability of PROMs used in CKD.

Abstract
OBJECTIVE To provide a disease-specific instrument for evaluating the health-related quality life of Chinese kidney allograft recipients. METHODS Cross-cultural adaptation of the Kidney Transplant Questionnaire (KTQ) was performed by forward translation of the original English version into Chinese, followed by back translation and evaluation of the Chinese version by health care professionals, language professionals, and the translators. RESULTS A total of 297 patients (110 women and 187 men; mean age, 43.91 ± 11.38 y; average time since transplant, 40.36 ± 32.86 mo) completed the Chinese versions of the KTQ and 36-Item Short Form Health Survey, and the results were used to evaluate the validity and reliability of the Chinese KTQ. The Cronbach α values for all KTQ dimensions were satisfactory (physical symptoms, α = 0.876; fatigue, α = 0.896; uncertainty/fear, α = 0.686; appearance, α = 0.701; and emotions, α = 0.886) and similar to values reported for the English and Spanish versions. The correlation coefficients among the dimensions of the Chinese KTQ ranged from 0.26 to 0.69, and those between the KTQ and 36-Item Short Form Health Survey physical component summary and mental component summary subscales were low and moderate to high, respectively, except for the appearance dimension. A good fit of the data in the confirmatory factor analysis indicated that the individual items of the translated instrument indeed evaluated the intended concepts. CONCLUSION The Chinese version of the KTQ was found to be similarly valid and reliable compared with the original version and, thus, can be used to evaluate health-related quality of life among Chinese adult kidney allograft recipients.

Abstract
INTRODUCTION Health benefits of a living-donor kidney transplantation are numerous and well known. There is, however, a dearth of knowledge on postoperative quality of life among the living-donor (LD) compared to deceased-donor (DD) transplant recipients. MATERIALS AND METHODS The study involved 89 patients after renal transplantation: 48 from LDs and 41 from DDs. Interview data indirectly indicated the patients' health, whereas physiological parameters directly pinpointed the patients' health and the graft function. All study participants completed questionnaires to measure quality of life and the specificity of emotional and cognitive functioning. RESULTS LD kidney recipients were younger than DD recipients (40 years vs. 49 years). LD and DD transplantation patients were similar in health status assessed by indirect methods (data from an interview) and direct methods (laboratory tests results). They, however, differed in their psychosocial functioning. LD patients had a greater sense of happiness (P < .01) and of self-efficacy (P = .07). Moreover, these patients were more actively involved in their social lives (P < .02) and were more satisfied with their social relationships (P = .07). LD recipients also had a higher quality of life in terms of mental functioning (P < .01) and satisfaction with their environments (P < .01). Additionally, there were significant correlations between quality of life and the quality of cognitive and emotional functioning in the group of LD recipients. The perceived impact of health on physical and professional activity and daily routines was similar in LD and DD groups. CONCLUSIONS LD post-transplantation patients may derive greater psychosocial benefits from this form of treatment. This effect is not dependent on somatic parameters (comparable data from an interview and laboratory tests results). This study suggests that patients should be assisted by a multidisciplinary healthcare team, and receive continuous support from relatives during the post-transplantation adaptation process. This facilitates the patients' postoperative quality of life.

Abstract
Background: Despite our knowledge of barriers to the early stages of the transplant process, we have limited insight into patient-reported barriers to the prekidney transplant medical evaluation in populations largely at-risk for evaluation failure. Methods: One-hundred consecutive adults were enrolled at an urban, Midwestern transplant center. Demographic, clinical, and quality of life data were collected prior to patients visit with a transplant surgeon/nephrologist (evaluation begins). Patient-reported barriers to evaluation completion were collected using the Subjective Barriers Questionnaire 90-days after the initial medical evaluation appointment (evaluation ends), our center targeted goal for transplant work-up completion. Results: At 90 days, 40% of participants had not completed the transplant evaluation. Five barrier categories were created from the 85 responses to the Subjective Barriers Questionnaire. Patient-reported barriers included poor communication, physical health, socioeconomics, psychosocial influences, and access to care. In addition, determinants for successful evaluation completion included being of white race, higher income, free of dialysis, a lower comorbid burden, and reporting higher scores on the Kidney Disease Quality of Life subscale role-emotional. Conclusion: Poor communication between patients and providers, and among providers, was the most prominent patient-reported barrier identified. Barriers were more prominent in marginalized groups such as ethnic minorities and people with low income. Understanding the prevalence of patient-reported barriers may aid in the development of patient-centered interventions to improve completion rates.

Health-Related Quality of Life of Kidney Transplantation Patients: Results from the KoreaN Cohort Study for Outcome in Patients With Kidney Transplantation (KNOW-KT) Study. Transplant Proc 2017; 48:844-7. [PMID: 27234749 DOI: 10.1016/j.transproceed.2015.12.101] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2015] [Accepted: 12/30/2015] [Indexed: 11/17/2022]
Abstract
BACKGROUND As patient and graft survival rates have been improving after kidney transplantation, health-related quality of life (HR-QOL) has become an important indicator of effective treatment. This study aimed to evaluate changes in HR-QOL after kidney transplantation. MATERIALS AND METHODS The KoreaN cohort study for Outcome in patients With Kidney Transplantation (KNOW-KT) is a multicenter, observational, 9-year, cohort study. The HR-QOL of patients in the KNOW-KT study was assessed before transplantation and 2 years after transplantation using the Kidney Disease Quality of Life Short Form (KDQOL-SF) including chronic kidney disease targeted area and the Medical Outcome Study 36-item Short Form Health Survey (SF-36). Multivariate linear regression was used to identify significant factors associated with follow-up QOL scores. RESULTS A total of 175 patients from 8 centers were analyzed. All QOL scores including the total QOL score, chronic kidney disease targeted score, and SF-36 at the 2-year follow-up were significantly increased compared to baseline values. Both physical and mental scale scores were improved after transplantation. CONCLUSION The QOL scores for both the mental and physical scales were improved at 2 years after kidney transplantation. High glomerular filtration rate at 2 years, high baseline QOL score, and low body mass index were associated with good follow-up QOL scores. Kidney transplantation for an Asian population with end-stage renal disease can result in better QOL as well as better patient and graft survival.

Predictors of Health-Related Quality of Life in Patients with Co-Morbid Diabetes and Chronic Kidney Disease. PLoS One 2016; 11:e0168491. [PMID: 27992595 PMCID: PMC5167387 DOI: 10.1371/journal.pone.0168491] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2016] [Accepted: 12/01/2016] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND People living with diabetes and chronic kidney disease (CKD) experience compromised quality of life. Consequently, it is critical to identify and understand factors influencing their health-related quality of life (HRQoL). This study examined factors associated with HRQoL among patients with diabetes and CKD. METHODS A cross sectional study among adults with comorbid diabetes and CKD (eGFR <60 mL/min/1.73m2) recruited from renal and diabetes clinics of four large tertiary referral hospitals in Australia was performed. Each participant completed the Kidney Disease Quality of Life (KDQoL ™ -36) questionnaire, which is comprised of two composite measures of physical and mental health and 3 kidney disease specific subscales with possible scores ranging from 0 to 100 with higher values indicating better HRQoL. Demographic and clinical data were also collected. Regression analyses were performed to determine the relationship between HRQoL and potential predictor factors. RESULTS A total of 308 patients were studied with a mean age of 66.9 (SD = 11.0) years and 70% were males. Mean scores for the physical composite summary, mental composite summary, symptom/problem list, effects of kidney disease and burden of kidney disease scales were 35.2, 47.0, 73.8, 72.5 and 59.8 respectively. Younger age was associated with lower scores in all subscales except for the physical composite summary. Female gender, obese or normal weight rather than overweight, and smoking were all associated with lower scores in one or more subscales. Scores were progressively lower with more advanced stage of CKD (p<0.05) in all subscales except for the mental composite summary. CONCLUSION In patients with diabetes and CKD, younger age was associated with lower scores in all HRQoL subscales except the physical composite summary and female gender, obese or normal weight and more advanced stages of CKD were associated with lower scores in one or more subscales. Identifying these factors will inform the timely implementation of interventions to improve the quality of life of these patients.

Abstract
BACKGROUND The purpose of renal transplantation is to achieve a maximal improvement in quality of life (QoL) and life expectancy in patients with end-stage renal disease (ESRD) while minimizing the potential side effects of this procedure. It is important to achieve an optimal balance between graft function and the patient's QoL. This study was designed to assess the changes in the QoL after kidney transplantation (KTx) in patients with ESRD previously treated with hemodialysis (HD) or peritoneal dialysis (PD). METHODS QoL was prospectively analyzed in 69 patients after kidney transplantation in a single-center study. Patients with ESRD were divided into 2 groups: those previously treated with HD (n = 44 patients; group 1) or PD (n = 25 patients; group 2). Both groups were asked to complete the KDQOL-SFtm questionnaire before and 12 months after kidney transplantation. RESULTS We observed significant differences in many parameters of QoL in both groups after KTx but more positive changes of most parameters in question exhibited by patients previously treated by means of HD than PD. Patients treated with HD and PD demonstrated improvement after KTx in 74% of dimensions. There were no statistical differences in the QoL between group 1 and group 2 before or after KTx. CONCLUSIONS The study demonstrated post- to pre-transplant improvements of QoL independently of previous treatment.

Abstract
BACKGROUND Health related quality of life (HRQOL) is patient-reported, and an important treatment outcome for patients undergoing renal replacement therapy. Whether HRQOL in dialysis can affect mortality or graft survival after renal transplantation (RTX) is not determined. The aims of the present study were to investigate whether pretransplant HRQOL is associated with post-RTX patient survival or graft function, and to assess whether improvement in HRQOL from dialysis to RTX is associated with patient survival. METHODS In a longitudinal prospective study, HRQOL was measured in 142 prevalent dialysis patients (67 % males, mean age 51 ± 15.5 years) who subsequent underwent renal transplantation. HRQOL could be repeated in 110 transplant patients 41 (IQR 34-51) months after RTX using the self-administered Kidney Disease and Quality of Life Short Form (KDQOL-SF) measure. Kaplan-Meier plots were utilized for survival analyses, and linear regression models were used to address HRQOL and effect on graft function. RESULTS Follow-up time was 102 (IQR 97-108) months after RTX. Survival after RTX was higher in patients who perceived good physical function (PF) in dialysis compared to patients with poorer PF (p = 0.019). Low scores in the domain mental health measured in dialysis was associated with accelerated decline in graft function (p = 0.048). Improvements in the kidney-specific domains "symptoms" and "effect of kidney disease" in the trajectory from dialysis to RTX were associated with a survival benefit (p = 0.007 and p = 0.02, respectively). CONCLUSION HRQOL measured in dialysis patients was associated with survival and graft function after RTX. These findings may be useful in clinical pretransplant evaluations. Improvements in some of the kidney-specific HRQOL domains from dialysis to RTX were associated with lower mortality. Prospective and interventional studies are warranted.

Abstract
BACKGROUND Kidney transplant patients on tolerance protocols avoid the morbidity associated with the use of conventional chronic immunosuppressive regimens. However, the impact of tolerance versus conventional regimens on the quality of life (QOL) of kidney transplant patients is unknown. METHODS Five patients who achieved long-term immunosuppression-free renal allograft survival after combined kidney and bone marrow transplantation (tolerant group) were compared with thirty-two comparable kidney transplant recipients on conventional immunosuppression (conventional group). QOL was compared with 16 conventional recipients using the Kidney Disease Quality of Life Short Form 36 (KDQOL SF-36) and the Modified Transplant Symptom Occurrence and Symptom Distress Scale (MTSOSD-59R). RESULTS Patients in the tolerant group required significantly less treatment after transplant for hypertension and no medications for diabetes (P < 0.01). There was no incidence of diabetes, dyslipidemia, or malignancies in the tolerant group, while these were observed in 12.5%, 40.6%, and 11.8% of the conventional group, respectively. Tolerant patients experienced better overall health (P < 0.01) and scored higher on kidney transplant-targeted scales and healthy survey scales than patients in the conventional group according to the KDQOL SF-36 (P < 0.05). Tolerant patients were less likely to experience depression, dyspnea, excessive appetite/thirst, flatulence, hearing loss, itching, joint pain, lack of energy, muscle cramps, and lack of libido than conventional patients according to the MTSOSD-59R (P < 0.05). CONCLUSION Kidney transplant recipients who achieved tolerance experience significantly fewer incidences of complications, improved QOL, and fewer comorbid symptoms compared with patients on conventional immunosuppression. These results support the expanded use of tolerance protocols in kidney transplantation.

Abstract
This study aimed to measure the religiosity and health-related quality of life of Filipino Christian HD patients. A cross-sectional study of 100 HD patients was conducted. The Duke University Religion Index and the Ferrans and Powers QLI Dialysis Version-III were used. Data were analyzed using descriptive statistics and Pearson r correlation. Attendance to organizational religious activities and NORA were found to be correlated with some of the dimensions of HRQoL. Intrinsic religiosity showed a strong, positive correlation with HRQoL. It is essential to attend to and nourish their religious needs. Holistic approach in providing care to HD patients, with emphasis on spiritual care, is encouraged to improve their total health.

Abstract
CONTEXT Patients on dialysis experience multiple concurrent and often related symptoms defined as symptom clusters. Renal transplantation (RTX) is thought to reduce symptom experience and improve health-related quality of life. No longitudinal study has assessed symptoms and symptom clusters in patients in the transition from dialysis to RTX. OBJECTIVES We aimed to assess changes in symptom prevalence, identify symptom clusters after RTX, and evaluate the effect of the treatment conversion on predefined symptom clusters. METHODS A cohort of patients on chronic dialysis (n = 110) was followed prospectively with measurements of health-related quality of life using the Kidney Disease and Quality of Life-Short Form (KDQOL-SF) during dialysis (baseline) and after subsequent RTX. Predefined symptom clusters based on 11 symptoms listed in KDQOL-SF were previously generated using principal component analysis with varimax rotation, that is, uremic (nausea, lack of appetite, dizziness, feeling squeezed out, shortness of breath, and chest pain), neuromuscular (numbness, sore muscle, and cramps), and skin (itching and dry skin) clusters. Stratified analyses were undertaken to identify characteristics associated with change in the symptom clusters after RTX. Cohen's d was used as effect size. RESULTS Of the 110 patients, mean age was 51.3 ± 14.4 years, and 66% were males. After RTX, the estimated glomerular filtration rate was 54 (interquartile range [IQR] 45-72) mL/minute/1.73 m2. Median follow-up time from assessments during dialysis was 55 (IQR 50-59) months, and follow-up time after RTX was 41 (IQR 34-51) months. The total symptom score improved (73 ± 16 vs. 82 ± 15, P = 0.001, and Cohen's d = 0.6), and the number of symptoms was reduced (6.5 ± 2.6 vs. 4.7 ± 3.0, P = 0.001). Seven symptoms improved statistically after RTX, but only two with Cohen's d > 0.5 (itching and cramps). The scores of the predefined symptom clusters improved after RTX: uremic (82 ± 16 vs. 85 ± 17, P = 0.008, and Cohen's d = 0.2), neuromuscular (66 ± 24 vs. 79 ± 18, P = 0.001, and Cohen's d = 0.6), and skin cluster (62 ± 27 vs. 78 ± 22, P = 0.001, and Cohen's d = 0.6). Symptom clusters could not be generated after RTX. CONCLUSION Although symptoms and symptom clusters were reduced after RTX, the clinical relevance of the reductions was ambiguous. Symptom clusters could not be generated after RTX, suggesting that use of the KDQOL-SF may not be optimal to assess symptoms in RTX patients.

Abstract
As medical advances are made in the care of persons with chronic illnesses including those with end-stage renal disease (ESRD), patients are not only experiencing increasing life expectancy but also bearing the burden of illness and treatment for a longer duration of time. With this in mind, it is increasingly important for health care providers to pay close attention to their individual patient's perceptions of their health, fitness, life satisfaction, and well-being. This assessment of Health-Related Quality of Life (HRQOL) also includes an evaluation of the patient's level of satisfaction with treatment, outcome, and health status, also taking into account their perspective on future prospects. In addition to improving patient-provider communication by helping in the identification and prioritization of problems, it is important to note that high HRQOL has been shown to be associated with better medical outcomes, including reduction in hospitalizations and death. In this review, we outline several validated tools that are used to quantitatively measure HRQOL in the ESRD population and incorporate these instruments in a review of specific, evidence-based measures by which we can measurably improve health-related quality of life in dialysis patients.

Abstract
BACKGROUND The impact of dialysis on patient quality of life has been recognized as an important outcome measure. The Dialysis Outcomes and Practice Patterns Study compared quality of life in 4 continents [1], but very scarce information is available about dialysis patients' quality of life in Africa. The objective of this study was to translate the Kidney Disease Quality of Life-Short Form (KDQOL-SF) into Moroccan and measure its psychometric properties. METHODS The questionnaire was first translated into Moroccan by 2 independent translators, and then 2 backward translations into English were performed after pretesting in 10 dialysis patients. The final questionnaire was then administered to 80 dialysis patients. Reliability was estimated by internal consistency and test-retest reliability. Validity was assessed using known group comparisons and correlations between overall health rating and scales scores. RESULTS Some activities were substituted since they were not common in Morocco. All subscales had a Cronbach α above the recommended value except for 3 scales. All of the items showed good test-retest reliability. Correlation of items within subscales was higher than that of items outside subscales in 87% of cases. Regarding construct validity, all KDQOL-SF scales had significant correlation with overall health rating except for sexual function and dialysis staff encouragement. Furthermore, the questionnaire could be used to discriminate between subgroups of the patients. CONCLUSIONS The psychometric properties of the KDQOL-SF resulting from this first-time administration of the instrument support the validity and reliability of the KDQOL-SF as a measure of quality of life of patients having hemodialysis in Morocco.

Abstract
PURPOSE The primary objective of this study is to measure hemodialysis patients' satisfaction with their vascular access. The secondary objective is to evaluate the measurement tool's psychometric properties to assess patient satisfaction with their vascular access. METHODS We generated a comprehensive list of survey items related to patients' views and satisfaction with their vascular access and administered it to participating in-center hemodialysis patients over 4 months. Following a factor analysis, the items were reduced and rescaled to generate the final short-form vascular access questionnaire (SF-VAQ). The SF-VAQ was then administered to a new cohort of hemodialysis patients on two occasions 1 week apart from February 1, 2012, to April 1, 2014. A repeated measures analysis of variance and psychometric evaluation was conducted. RESULTS The final SF-VAQ with 13 items and four domains was administered to 132 patients (35 fistulas, 14 grafts and 83 catheters). The mean Likert value for overall satisfaction on a scale of 1 (low) to 7 (high) was 5.98, with catheters, fistulas and grafts with values of 5.92, 6.46 and 5.21, respectively. The test-retest reliability for two occasions is 0.92 and the internal consistency for the first administration is high at 0.84. CONCLUSIONS The SF-VAQ is a short, simple to administer vascular access-specific questionnaire with robust psychometric properties that can be used to obtain the patient's views on their vascular access. Based on the newly developed SF-VAQ, patients were the most satisfied with fistulas, scores.

Abstract
Background Little is known how health related quality of life (HRQOL) change in the transition from dialysis to renal transplantation (RTX). Longitudinal data addressing the patient-related outcomes are scarce, and particularly data regarding kidney-specific HRQOL are lacking. Thus, the aim of the current study was to assess HRQOL in patients followed from dialysis to RTX. Furthermore, to compare HRQOL in RTX patients and the general population. Methods In a prospective study, HRQOL was measured in a cohort of 110 patients (median age 53.5 (IQR 39–62) years, GFR 54 (45–72) ml/min/1.73 m2) in dialysis and after RTX using the self-administered Kidney Disease and Quality of Life Short Form version 1.3 (KDQOL-SF). Generic HRQOL in the RTX patients was compared to that of the general population (n = 5903) using the SF-36. Clinical important change after RTX was defined as difference in HRQOL of SD/2. Results Follow-up time was 55 (IQR 50–59) months, and time after RTX was 41 (34–51) months. Four of nine domains in kidney-specific HRQOL improved after RTX, i.e. burden of kidney disease, effect of kidney disease, symptoms and work status. In SF-36, general health, vitality, social function and role physical improved after RTX, but none of the domains improved sufficiently to be regarded as clinically relevant change. There were highly significant differences in HRQOL between RTX patients and the general population after adjustment for age and gender for all items of SF-36 except for bodily pain and mental health. Conclusions HRQOL improved in the transition from dialysis to transplantation, but clinical relevant change was only obtained in the kidney specific domains. HRQOL was perceived considerably poorer in RTX patients than in the general population. Our observations point to the need of improving HRQOL even after RTX, and should encourage further longitudinal research and clinical attention during treatment shift.

Abstract
BACKGROUND The Epidemiology Network and Nephrology Information provides since 2001 the epidemiological monitoring of end stage renal disease (ESRD) in France. Two cross-sectional studies to estimate the level of quality of life in ESRD patients were performed in 2005 and 2007 and repeated in 2011. The main objective is to analyze the evolution of the quality of life of ESRD between these two surveys. METHODS The studies were conducted on a representative sample of subjects aged 18 and over, prevalent dialysis or holders of a functioning kidney transplant last year, followed in center dialysis and/or transplantation in one of the eight French regions selected. The quality of life was measured by a generic questionnaire, and two specifics questionnaires. RESULTS The evolution of the quality of life deteriorated slightly between 2005-2007 and 2011. There is however few dimensions affected. The variation in scores is not meaningful in general, with maximum decreases less than 4 points according to the statistical methods used. This diminution is not clinically significant. DISCUSSION The quality of life in dialysis patients or transplant did not evolve between 2005-2007 and 2011. Currently, it is difficult to assess the benefits of the national plan for improving the quality of life of people with chronic diseases because the last data are too close to the end of the plan.

Abstract
Background Health-related quality of life is a crucial outcome for the chronic kidney disease population, the Kidney Disease Quality of Life (KDQOL) questionnaire is commonly used as an integral part of clinical evaluations. The abbreviated version of the KDQOL-36™ has been translated into Mandarin Chinese, but has not been tested for use in the Chinese patients. The aim of the study was to evaluate the validity and reliability of the KDQOL-36™ with a sample of Chinese patients. Methods The Mandarin Chinese version of the KDQOL-36™ has been translated by Amgen, Inc. and the MAPI Institution following the instrument translation specifications provided by the RAND health. The translated instrument was further reviewed by a Chinese expert panel for content validity and translational equivalence. The KDQOL-36™ along with Beck depression Inventory-II were administrated to 103 chronic renal disease patients recruited through convenience sampling procedure from the renal wards and an outpatient dialysis clinic. The convergent validity was determined through investigating the correlational evidence of the KDQOL-36™ with the Beck depression Inventory-II and the overall health rating. Known-group validity was supported by the evidence that the instrument could differentiate subgroups of patients. The internal consistency was estimated using Cronbach’s α and test-retest reliability was examined using an intraclass correlation coefficient. Results For the convergent validity, there were positive correlations between the overall health rating and most of the KDQOL-36™ subscales, and the Beck depression inventory score was inversely correlated with the mental component summary score and disease-specific scores of the scale. Significant correlations were noted between disease-targeted and generic dimensions of the KDQOL-36™. The results of the known-group comparisons indicated females, the unemployed, and patients had a longer dialysis history reported a worse quality of life. With regard to the reliability, the Cronbach’s alpha ranged from 0.69 to 0.78, and the intraclass correlation test-retest was higher than 0.70. Conclusions The Mandarin Chinese version of the KDQOL-36™ is a brief, valid, and reliable instrument for use in examining the quality of life of chronic kidney disease patients in China.

Abstract
A psychometric evaluation of the 36-item short-form health survey (SF-36) was undertaken in contemporary studies to assess its suitability for use in an alcohol-dependent population. Three criteria were used to try and determine this: factor analysis, internal consistency reliability and test-retest reliability. Factor analysis revealed that it is mainly consistent with a bidimensional model, internal consistency reliability showed that it consistently provided scores above the recommended threshold and test-retest reliability of the SF-36 highlights that it too provided higher than suggested scores. A conclusion was reached recommending the SF-36 as a reliable screening tool in an alcohol-dependent population, but this is given in caution as no studies were found analysing the instrument in this population.

Abstract
PURPOSE Chronic kidney disease has profound effects on the health-related quality of life (HRQoL) of patients, with serious physiological, psychological and socio-economic implications. The co-occurrence of protein-energy wasting and inflammation in end-stage renal disease patients is associated with worse HRQoL and increased mortality. We designed this study to examine the relationship between nutritional and inflammatory status and HRQoL in kidney transplant recipients. METHODS Data from 100 randomly selected kidney transplant patients were analyzed in a cross-sectional survey. Socio-demographic parameters, laboratory results, transplantation-related data, comorbidities, medication and malnutrition-inflammation score (MIS) (Kalantar Score) were tabulated at baseline. Patients completed the Kidney Disease Quality of Life-SF (KDQoL-SF™) self-administered questionnaire. RESULTS Mean age was 51 ± 13 years, median (interquartile range, IQR) time since transplantation 66 (83) months, 57% were men, and 19% had diabetes. The median (IQR) MIS was 3 (3). The MIS significantly and negatively correlated with almost all HRQoL domains analyzed, and this association remained significant in multivariate linear regression analysis for the log-transformed scores on energy/fatigue (β = -0.059 P < 0.001), bodily pain (β = -0.056 P = 0.004), physical functioning (β = -0.029, P = 0.022) and symptoms/problems (β = -0.023 P = 0.005) domains after statistical correction for age, gender, eGFR, dialysis vintage, Charlson Comorbidity Index and occupational status. Additionally, cubic spline analyses revealed linearly increasing, "dose-response" relationship between almost all domains of KDQoL-SF™ and the MIS. CONCLUSIONS Malnutrition-inflammation score is independently associated with different dimensions of HRQoL in kidney transplant recipients.

Abstract
Advances in healthcare, combined with an increasing number of adults with end-stage renal disease (ESRD), mean that there is a growing number of people now surviving on renal replacement therapy. The issue of health-related quality of life (HR-QOL) is becoming increasingly important in this area. For this reason, the content validity of various instruments used to measure HR-QOL in an ESRD population were explored. Systematic searches of MEDLINE (1950-2009) were conducted using terms related to ESRD combined with terms associated with measuring HR-QOL. A total of 378 abstracts were identified, detailing the repeated use of six generic measures and four disease-specific measures. The generic HR-QOL measures discussed include the Medical Outcomes 36-Item Short Form Survey (SF-36), the EuroQOL 5 Dimension (EQ-5D), and the WHO QOL assessment (WHOQOL-BREF). The most frequently used disease-specific measure discussed is the Kidney Disease QOL instrument (KDQOL) and its derivative versions (KDQOL-SF, KDQOL-36). The appropriateness of using the SF-36 in this population is challenged and recommendations include using the WHOQOL-BREF in cases when a generic instrument is required and the KDQOL-SF when a more disease-specific measurement is called for.
