Living with Chronic Kidney Disease: Illness Perceptions, Symptoms, Coping, and Quality of Life

The purpose of this study was to explore how illness perceptions, specifically intrusiveness, impact individuals with chronic kidney disease living with dialysis therapy and kidney transplants, and to determine the relationships among illness perceptions, symptoms, coping, and quality of life (QoL). Forty-two individuals on dialysis and with renal transplants completed an online survey. We found strong relationships between illness intrusiveness, symptom scores, and QoL. Illness intrusiveness was highly disruptive to one's financial situation, health, and work. Intrusiveness was also significantly related to individual symptoms, especially tiredness, feelings of well-being, and sleep. Correlations between intrusiveness and QoL were significant. Emotion-focused coping strategies were also significantly associated with intrusiveness. Health professionals can target illness perceptions, symptom burden, and coping strategies to enhance QoL.

Limited Knowledge of Chronic Kidney Disease among Type 2 Diabetes Mellitus Patients in India

Diabetes and hypertension are the two major causes of chronic kidney disease (CKD). Epidemiological studies have found poor knowledge about the CKD among the general population. Hence, this study aimed to assess the awareness of CKD among type 2 diabetes mellitus (T2DM) patients in India. Patients with confirmed T2DM were included in the study. Patients receiving dialysis or with a history of a kidney transplant were excluded. A validated questionnaire was used to assess knowledge about CKD. Demographic characteristics were presented using descriptive statistics and trends in groups were calculated using the chi-square test. Statistical analysis was performed using SAS v9.4. A total of 323 patients completed the study. The mean age of the patients was 56 ± 11.25 years, and 51.7% were female. Only 33.43% of the patients correctly identified diabetes and hypertension as risk factors for CKD, while 44.27% were aware of the kidney's function. Statistically significant associations were observed between kidney disease knowledge and education status (p = 0.004), socioeconomic status (p = 0.000), and income status (p = 0.003). No association was observed between the knowledge about CKD and age, gender, hypertension stages, CKD stages, duration of diabetes as well as hypertension and co-morbidities. Based on the results of this study, we found poor knowledge of CKD among Indian T2DM patients. The government should start a CKD awareness programme to deal with this rising co-morbid condition.

Examining Uncertainty in Illness in Parents and Children With Chronic Kidney Disease and Systemic Lupus Erythematosus: A Mediational Model of Internalizing Symptoms and Health-Related Quality of Life

To examine if parent illness uncertainty is indirectly associated with child depression, anxiety, and HRQOL in the CKD/SLE population. Parent-child dyads (N = 31) from outpatient rheumatology and nephrology clinics included children (ages 9-18) diagnosed with CKD (Stage 1, 2, or nephrotic syndrome) or SLE. Parents completed demographic and uncertainty measures and children completed uncertainty, depression, anxiety, and HRQOL measures. This cross-sectional study examined mediational models using the percentile bootstrapping method. Parent uncertainty had an indirect effect on child depression, anxiety, and HRQOL through the mediator, child uncertainty. In other words, parents' illness uncertainty regarding their child's condition correlates to the child's illness uncertainty, which then is associated with the child's mental health and wellbeing. Reverse mediations illustrated that parent uncertainty did not mediate child uncertainty and outcome variables. Results extend previous research by examining parent and child illness uncertainty in understudied conditions (CKD/SLE) and the relationship to outcome variables commonly related to depression (e.g., anxiety and HRQOL). Findings allow health psychologists and medical personnel to understand the impact of uncertainty on the child's wellbeing and HRQOL. Clinical implications, including using specialized interventions to address illness uncertainty, are discussed.

Academic achievement in children with chronic kidney disease: a report from the CKiD cohort

BACKGROUND

There are limited data to describe academic achievement outcomes for children with mild to moderate pediatric chronic kidney disease (CKD). The objective of this study was to describe the prevalence of low academic achievement in patients with mild to moderate CKD.

METHODS

Wechsler Individual Achievement Test, Second Edition, Abbreviated (WIAT-II-A) data were collected at entry into the Chronic Kidney Disease in Children (CKiD) study. Achievement in basic reading, spelling, mathematics, and total achievement was evaluated with a focus on the effects of comorbid CKD-related variables, neurocognitive, and school-based characteristics on academic achievement.

RESULTS

WIAT-II-A data were available for 319 children in the CKiD cohort. Low total academic achievement was present in 34% percent of the sample. There was no significant effect of CKD-related medical variables on academic achievement. Mathematics had the lowest distribution of achievement scores. In univariate models, low achievement was significantly related to days of missed school (p = 0.006) and presence of individualized education plan (p < 0.0001).

CONCLUSIONS

Low academic achievement was seen in over one-third of children with CKD, with the most difficulty observed in the domain of mathematics. Providers and educators should monitor for academic difficulties in this population in order to facilitate early educational assistance and promote positive educational outcomes.

Moderating Effects of Forgiveness on Relationship Between Empathy and Health-Related Quality of Life in Hemodialysis Patients: A Structural Equation Modeling Approach

CONTEXT

Health-related quality of life (QOL) is a recommended clinical tool to assess hemodialysis patients and a primary end point to observe the effectiveness of overall disease management. Empathy is associated with positive outcomes such as pain relief and reduced anxiety and distress. Numerous studies have tested the relationships among empathy, forgiveness, and QOL; however, a mechanism of forgiveness has not been fully explored in hemodialysis patients.

OBJECTIVES

To test the relationship among empathy and health-related QOL and confirm the moderating effects of forgiveness on relationship between empathy and health-related QOL among hemodialysis patients.

METHODS

In a descriptive cross-sectional study conducted from September to December 2017, 457 hemodialysis patients from five hospitals filled out the Heartland Forgiveness Scale, Interpersonal Reactivity Index-C, Kidney Disease Questionnaire, and general information. The data were analyzed using SPSS, and structural equation modeling was used to address the relationships among empathy, forgiveness, and health-related QOL.

RESULTS

Empathy was significantly positively associated with health-related QOL. The proposed model had a good fit to the data. Forgiveness was found to play a partial mediating role between empathy and health-related QOL.

CONCLUSION

The results imply that empathy significantly directly and indirectly influences health-related QOL. Empathy among hemodialysis patients should be monitored and effectively managed to improve positive effects on their health-related QOL. Nurses should consider implementing empathy interventions with an emphasis on building forgiveness strategies to help hemodialysis patients improve their health-related QOL.

The patient experience of kidney disease and pregnancy

Achieving parenthood is often a priority and goal for women with chronic kidney disease (CKD). It can be challenging due to medical and emotional complexities around pregnancy planning and care, increased risk of adverse maternal and fetal outcomes, fears about medications such as immunosuppressants and fetal harm, and concerns regarding the impact of pregnancy on women's kidney health. Navigating the pathways for shared decision-making regarding parenthood requires an understanding of the patient's experiences, values, priorities, and needs. In this review, we describe the patient perspective of high-risk pregnancies including those complicated by CKD and outline recommendations for counseling that incorporate these perspectives to improve the patient experience.

Patterns and predictors of depression treatment among adults with chronic kidney disease and depression in ambulatory care settings in the United States

PURPOSE

One in five adults with chronic kidney disease (CKD) in the United States (US) suffers from depression. Comorbid depression in adults with CKD is associated with higher morbidity and mortality. This study used US national survey data to examine patterns and predictors of depression treatment among adults with non-dialysis-dependent CKD in the US.

METHODS

A retrospective, cross-sectional study was conducted using 2014-2015 National Ambulatory Medical Care Survey (NAMCS) data. The final study sample consisted of visits by 9.02 million adults (unweighted n = 262; age ≥ 18 years) with CKD and depression in the US. Depression treatment was defined as antidepressant use with or without psychotherapy. To identify predictors of depression treatment, multivariable logistic regression analysis was conducted adjusting for predisposing, enabling, and need factors.

RESULTS

Approximately half of adults with CKD and depression received depression treatment. Primary care was the main setting of treatment, and the most commonly prescribed antidepressant class was selective serotonin reuptake inhibitors. Adults being seen for treatment of a chronic problem were 3.2 times more likely to receive depression treatment (OR 3.20; 95% CI 1.38-7.21). In addition, there was a 9% higher likelihood of receiving depression treatment for each unit increase in total number of medications (OR 1.09; 95% CI 1.01-1.19). Finally, adults receiving care in the South were 63% less likely to receive depression treatment (OR 0.37; 95% CI 0.15-0.89).

CONCLUSIONS

Depression treatment was recorded in approximately half of US ambulatory care visits involving adults with CKD and depression from 2014 to 2015. Further research is warranted to determine how to appropriately manage treatment of depression in adults with CKD.

Patient reported barriers are associated with low physical and mental well-being in patients with co-morbid diabetes and chronic kidney disease

BACKGROUND

Little is known about how patient reported barriers to health care impact the quality of life (HRQoL) of patients with comorbid disease. We investigated patient reported barriers to health care and low physical and mental well-being among people with diabetes and chronic kidney disease (CKD).

METHODS

Adults with diabetes and CKD (estimated Glomerular Filtration Rate < 60 ml/min/1.73m2) were recruited and completed a questionnaire on barriers to health care, the 12-Item HRQoL Short Form Survey and clinical assessment. Low physical and mental health status were defined as mean scores < 50. Logistic regression models were used.

RESULTS

Three hundred eight participants (mean age 66.9 ± 11 years) were studied. Patient reported 'impact of the disease on family and friends' (OR 2.07; 95% CI 1.14 to 3.78), 'feeling unwell' (OR 4.23; 95% CI 1.45 to 12.3) and 'having other life stressors that make self-care a low priority' (OR 2.59; 95% CI 1.20 to 5.61), were all associated with higher odds of low physical health status. Patient reported 'feeling unwell' (OR 2.92; 95% CI 1.07 to 8.01), 'low mood' (OR 2.82; 95% CI 1.64 to 4.87) and 'unavailability of home help' (OR 1.91; 95% CI 1.57 to 2.33) were all associated with higher odds of low mental health status. The greater the number of patient reported barriers the higher the odds of low mental health but not physical health status.

CONCLUSIONS

Patient reported barriers to health care were associated with lower physical and mental well-being. Interventions addressing these barriers may improve HRQoL among people with comorbid diabetes and CKD.

Telemonitoring system for patients with chronic kidney disease undergoing peritoneal dialysis: Usability assessment based on a case study

There are two million people with chronic kidney disease (CKD) worldwide. In Mexico, it is estimated that by 2025, there will be 212 thousand CKD cases. Among the renal replacement treatments, peritoneal dialysis (PD) exists either in the continuous ambulatory (CAPD) or automated (APD) mode, which requires continuous monitoring and strict control. Thus, several software systems have been proposed to perform reliable remote monitoring of patients using PD but also to achieve the goal with effectiveness, efficiency and satisfaction; i.e., in software engineering, this is called usability. However, few studies have addressed usability issues using case studies with patients and medical staff in real domains. In this paper, we present a usability assessment of a telemonitoring system for patients with CKD on peritoneal dialysis treatment through a case study with patients and medical staff of the Mexican Institute of Social Security (IMSS). The usability evaluation was carried out through the application of two satisfaction instruments. These instruments evaluated multiple usability criteria, such as navigability, interactivity, motivation, satisfaction, and applicability. The results obtained from the usability evaluation show that, on average, the services offered by the system have 91.3% acceptance by users (patient-doctors), with the APD and CAPD exchange data registration services having the highest acceptance for patients, with a positive perception of 94.5% and 92.3%, respectively. Meanwhile, for the doctors and nurses, the alarm reception for patients in a risk situation was highest with 95% acceptance. Based on the obtained results, the evaluated telemonitoring system holds wide acceptance, satisfaction, and applicability from patients’ and doctors’ perspectives. It is also noted that the evaluated system considers and satisfies the requirements and suitable parameters that should be monitored in PD treatment according to studies presented in the literature.

Advance Care Planning and Chronic Kidney Disease: What Do Patients Know and What Do They Want?

There is a gap in the research literature regarding advance care planning with this population of patients. This article reports on a study about the end-of-life knowledge, needs, and preferences of patients on hemodialysis - as reported by patients - within a hospital or community-based setting that addresses this gap. Data were collected using a survey method; non-probability, consecutive sampling (n=133) resulted in a high response rate of 64.0%. There were three key findings: 1) patients do not identify themselves as having a progressive health condition, 2) patients are comfortable discussing end-of-life issues, and 3) patients want discussions about end-of-life care when they request to do so or when their health worsens. We report on these findings and discuss three key recommendations: 1) patients with chronic kidney disease be consulted about the appropriate time for advance care planning, 2) symptom management needs greater attention, and 3) the role of family requires more consideration.

Cognitive Impairment in Non-Dialysis-Dependent CKD and the Transition to Dialysis: Findings From the Chronic Renal Insufficiency Cohort (CRIC) Study

BACKGROUND

Advanced chronic kidney disease is associated with elevated risk for cognitive impairment. However, it is not known whether and how cognitive impairment is associated with planning and preparation for end-stage renal disease.

STUDY DESIGN

Retrospective observational study.

SETTING & PARTICIPANTS

630 adults participating in the CRIC (Chronic Renal Insufficiency Cohort) Study who had cognitive assessments in late-stage CKD, defined as estimated glome-rular filtration rate ≤ 20mL/min/1.73m2, and subsequently initiated maintenance dialysis therapy.

PREDICTOR

Predialysis cognitive impairment, defined as a score on the Modified Mini-Mental State Examination lower than previously derived age-based threshold scores. Covariates included age, race/ethnicity, educational attainment, comorbid conditions, and health literacy.

OUTCOMES

Peritoneal dialysis (PD) as first dialysis modality, preemptive permanent access placement, venous catheter avoidance at dialysis therapy initiation, and preemptive wait-listing for a kidney transplant.

MEASUREMENTS

Multivariable-adjusted logistic regression.

RESULTS

Predialysis cognitive impairment was present in 117 (19%) participants. PD was the first dialysis modality among 16% of participants (n=100), 75% had preemptive access placed (n=473), 45% avoided using a venous catheter at dialysis therapy initiation (n=279), and 20% were preemptively wait-listed (n=126). Predialysis cognitive impairment was independently associated with 78% lower odds of PD as the first dialysis modality (adjusted OR [aOR], 0.22; 95% CI, 0.06-0.74; P=0.02) and 42% lower odds of venous catheter avoidance at dialysis therapy initiation (aOR, 0.58; 95% CI, 0.34-0.98; P=0.04). Predialysis cognitive impairment was not independently associated with preemptive permanent access placement or wait-listing.

LIMITATIONS

Potential unmeasured confounders; single measure of cognitive function.

CONCLUSIONS

Predialysis cognitive impairment is associated with a lower likelihood of PD as a first dialysis modality and of venous catheter avoidance at dialysis therapy initiation. Future studies may consider addressing cognitive function when testing strategies to improve patient transitions to dialysis therapy.

Validation of the shortened Perceived Medical Condition Self-Management Scale in patients with chronic disease

Self-efficacy, or perceived competence, has been identified as an important factor in self-management behaviors and health outcomes in patients with chronic disease. Measures of self-management self-efficacy are currently available for multiple forms of chronic disease. One established measure is the 8-item Perceived Medical Condition Self-Management Scale (PMCSMS). This study investigated the use of the PMCSMS in samples of patients with a chronic disease to develop an abbreviated version of the scale that could be more readily used in clinical contexts or in large population health cohort studies. The PMCSMS was administered as either a generic scale or as a disease-specific scale. The results of analyses using item response theory and classical test theory methods indicated that using 4 items of the scale resulted in similar internal consistency (α = .70-0.90) and temporal stability (test-retest r = .75 after 2 to 4 weeks) to the 8-item PMCSMS (r = .81 after 2 to 4 weeks). The 4 items selected had the greatest discriminability among participants (α parameters = 2.49-3.47). Scores from both versions also demonstrated similar correlations with related constructs such as health literacy (r = .13-0.29 vs. 0.14-0.27), self-rated health (r = .17-0.48 vs. 0.26-0.50), social support (r = .21-0.32 vs. 0.25-0.34), and medication adherence (r = .20-0.24 vs. 0.20-0.25). The results of this study indicate that 4-item PMCSMS scores are equally valid but more efficient, and have the potential to be beneficial for both research and clinical applications.

Work of being an adult patient with chronic kidney disease: a systematic review of qualitative studies

INTRODUCTION

Chronic kidney disease (CKD) requires patients and caregivers to invest in self-care and self-management of their disease. We aimed to describe the work for adult patients that follows from these investments and develop an understanding of burden of treatment (BoT).

METHODS

Systematic review of qualitative primary studies that builds on EXPERTS1 Protocol, PROSPERO registration number: CRD42014014547. We included research published in English, Spanish and Portuguese, from 2000 to present, describing experience of illness and healthcare of people with CKD and caregivers. Searches were conducted in MEDLINE, Embase, CINAHL Plus, PsycINFO, Scopus, Scientific Electronic Library Online and Red de Revistas Científicas de América Latina y el Caribe, España y Portugal. Content was analysed with theoretical framework using middle-range theories.

RESULTS

Searches resulted in 260 studies from 30 countries (5115 patients and 1071 carers). Socioeconomic status was central to the experience of CKD, especially in its advanced stages when renal replacement treatment is necessary. Unfunded healthcare was fragmented and of indeterminate duration, with patients often depending on emergency care. Treatment could lead to unemployment, and in turn, to uninsurance or underinsurance. Patients feared catastrophic events because of diminished financial capacity and made strenuous efforts to prevent them. Transportation to and from haemodialysis centre, with variable availability and cost, was a common problem, aggravated for patients in non-urban areas, or with young children, and low resources. Additional work for those uninsured or underinsured included fund-raising. Transplanted patients needed to manage finances and responsibilities in an uncertain context. Information on the disease, treatment options and immunosuppressants side effects was a widespread problem.

CONCLUSIONS

Being a person with end-stage kidney disease always implied high burden, time-consuming, invasive and exhausting tasks, impacting on all aspects of patients' and caregivers' lives. Further research on BoT could inform healthcare professionals and policy makers about factors that shape patients' trajectories and contribute towards a better illness experience for those living with CKD.

Avoidable visits to the emergency department(ED) and their association with sex, age and race in a cohort of low socio-economic status patients on hemodialysis in the Bronx

Background

In national samples drawn from the USRDS, female patients utilize the hospital ED and inpatient services at a higher rate than their male counterparts and have a higher rate of re-hospitalization. We wanted to explore the association of sex with avoidable ED visits made by a cohort of patients on hemodialysis in a mostly minority, lower socioeconomic status (SES), population in the Bronx to test the applicability of the USRDS findings.

Methods

We used Montefiore’s clinical database to build a cohort of patients on hemodialysis with a first ED visit between 2013 and 2017. All ED visits after the index ED visit and those within one year prior to the index visit were recorded. None of the ED visits resulted in a hospitalization and were thus labeled “avoidable”. Bivariate analysis tested the association of demographic and clinical variables with sex. We used negative binomial regression to test the association of each variable with avoidable ED visit count. The multivariate model used negative binomial regression with avoidable ED visit count as outcome and sex as the exposure variable and included ancestral variables age and race. Potential mediators were added to the model to measure their effects on the association of sex with avoidable ED visits.

Results

Four thousand six hundred and seventy three subjects on hemodialysis were identified as having at least one avoidable ED visit, in the period of 2013–2017 at one of four ED sites affiliated with Montefiore Medical Center in the Bronx. Over 5 years (2012–2017), the median number of ED visits made by the study sample was 4 (25–75% IQR: 2–8). Female patients on hemodialysis in our cohort were older, more commonly black, had lower SES scores, less commonly had commercial insurance and were less commonly married than their male counterparts. Female sex was not significantly associated with a higher rate of avoidable ED visits in the total cohort.(1.053(0.99–1.12) Female sex was significantly associated with outcome in non-Hispanic whites only and in those subjects younger than 44 years old.(IRR 1.30(1.06–1.69), 1.17(1.00–1.38) in non-Hispanic White and younger age group, respectively.) Marital status, SES and hemoglobin levels possibly mediated the association of sex and outcome in our population. (>25% change in the coefficient for sex with respect to outcome when variable added to the model).

Conclusion

In this single center study of a lower-socioeconomic status, mostly minority dialysis population, the association of female sex with avoidable ED visits was not significant. These results suggest the association of sex with hospitalization outcomes, described by national datasets that determine quality indicators, are not consistent across different types of populations with some mediation possible by SES and marital status in poorer neighborhoods.

Social construction of the experience of living with chronic kidney disease

OBJECTIVE

To understand the experience of people living with Chronic Kidney Disease who have been transplanted, from the meanings constructed based on the experienced phenomenon.

METHOD

Hermeneutic-phenomenological study based on the five lifeworld existentials, according to Van Manen's theoretical framework. Eleven transplanted patients participated in the study and data collection was carried out through semi-structured interviews, after approval of the study by the Ethics Committee of the University of Antioquia.

RESULTS

The theme of Living with Chronic Kidney Disease emerged, and the subthemes were grouped as lifeworld existentials of Temporality: something unexpected, being present and not seeing it, being young and sick. Relationality: support, feeling stuck and Terminal Chronic Renal Failure. Spatiality: changes in life, sadness and depression. Corporeality: body deterioration and changes in sex life. Materiality: effects on the economic status.

CONCLUSIONS

The care provided to people must be oriented in order to recognize their individualities, understanding what the illness means for the individual and his family, how they live with it and what the changes are, leading them to modify their lives and start a long process, such as living with a chronic disease.

Symptoms, Coping, and Quality of Life of People with Chronic Kidney Disease

The purpose of this study was to explore how symptoms affect quality of life (QOL) for people living with chronic kidney disease (CKD) and kidney transplants, and to determine the relationship among various coping styles, symptoms, and QOL. An online survey was conducted; 42 people with CKD or a kidney transplant completed all parts of the survey. We found strong significant relationships between symptoms and QOL ratings. Problem-focused coping strategies were the most frequently employed, but there were few significant relationships between symptoms and coping, or between problem focused coping strategies and QOL. Future research should explore whether interventions to address emotion-focused coping strategies impact QOL as well as symptom burden.

[Comparative assessment of the quality of life of kidney transplant recipients and hemodialysis patients]

AIM

To compare the quality of life of chronic kidney disease (CKD) patients after kidney transplantation and hemodialysis patients.

MATERIAL AND METHODS

A prospective controlled trial comprised 110 CKD patients, divided into two groups. The study group included 51 (46.4%) kidney transplant recipients and 59 (53.6%) hemodialysis patients represented a control group. Assessment of health related quality of life was done using the KDQOL-SF questionnaire.

RESULTS

Kidney transplant recipients reported significantly greater satisfaction with their physical and emotional health than hemodialysis patients. Kidney transplant recipients experienced fewer somatic symptoms of CKD and everyday problems. It is very important that unlike hemodialysis patients transplant recipients were physically capable of working. There were no differences between groups regarding sleep quality, sexual activity, communication with others and time spent with family and friends.

CONCLUSION

Patients receiving long-term hemodialysis therapy experience a marked decrease in physical and mental components of QOL, whereas kidney transplantation results in better QOL for these parameters.

Determinants of quality of life as measured with variants of SF-36 in patients with predialysis chronic kidney disease

OBJECTIVES

To determine the average health-related quality of life (HRQOL) score levels and their determinants in patients with predialysis chronic kidney disease (CKD).

METHODS

A systematic literature search was conducted for relevant observational studies published between April 2007 and April 2017 in MEDLINE, EBSCOhost, and CINAHL databases.

RESULTS

Thirteen observational studies with a total sample of 8635 subjects comprising 53.3% male with an aggregate mean age of 59.5 (SD 14.9) years were included in this review. Of the 8 generic HRQOL domains of the Short-Form Health Surveys, Social Functioning had the highest mean score whereas General Health had the lowest mean score in patients with predialysis CKD. Physical component summary (PCS) was more impaired than mental component summary (MCS). The determinants of poor HRQOL in predialysis CKD patients included both modifiable risk factors such as comorbidities (namely anxiety and depression), low serum hemoglobin level, sedentary lifestyle, unemployment and non-modifiable risk factors such as poor glomerular filtration rate, female gender, and older age. The risk factors impeded PCS more than MCS.

CONCLUSION

Several risk factors influence HRQOL impairment in patients with predialysis CKD, with PCS being more impacted than MCS. The risk factors for poor HRQOL are important for future research and for improving renal care in patients with predialysis CKD.

Sleep Duration and Health-Related Quality of Life in Predialysis CKD

BACKGROUND AND OBJECTIVES

Sleep duration has been associated with cardiometabolic risk and mortality. The health-related quality of life represents a patient's comprehensive perception of health and is accepted as a health outcome. We examined the relationship between sleep duration and health-related quality of life in predialysis CKD.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

In this cross-sectional study, data from 1910 adults with CKD enrolled in the Korean Cohort Study for Outcome in Patients with CKD were analyzed. Health-related quality of life was assessed with the physical component summary and mental component summary of the Short Form-36 Health Survey. Low health-related quality of life was defined as a Short Form-36 Health Survey score >1 SD below the mean. Using a generalized additive model and multivariable logistic regression analysis, the relationship between self-reported sleep duration and health-related quality of life was examined.

RESULTS

Seven-hour sleepers showed the highest health-related quality of life. We found an inverted U-shaped relationship between sleep duration and health-related quality of life as analyzed by a generalized additive model. In multivariable logistic analysis, short sleepers (≤5 h/d) had lower health-related quality of life (odds ratio, 3.23; 95% confidence interval, 1.86 to 5.60 for the physical component summary; odds ratio, 2.37; 95% confidence interval, 1.43 to 3.94 for the mental component summary), and long sleepers (≥9 h/d) had lower health-related quality of life (odds ratio, 2.80; 95% confidence interval, 1.55 to 5.03 for the physical component summary; odds ratio, 2.08; 95% confidence interval, 1.20 to 3.60 for the mental component summary) compared with 7-hour sleepers. Sleep duration had a significant U-shaped association with low health-related quality of life.

CONCLUSIONS

These findings suggest that short or long sleep duration is independently associated with low health-related quality of life in adults with CKD.

Measurement properties of the Short Form-36 (SF-36) and the Functional Assessment of Cancer Therapy - Anemia (FACT-An) in patients with anemia associated with chronic kidney disease

BACKGROUND

Anemia is a common and debilitating manifestation of chronic kidney disease (CKD). Data from two clinical trials in patients with anemia of CKD were used to assess the measurement properties of the Medical Outcomes Survey Short Form-36 version 2 (hereafter SF-36) and the Functional Assessment of Cancer Therapy-Anemia (FACT-An). The Vitality and Physical functioning domains of the SF-36 and the FACT-An Total, Fatigue and Anemia subscales were identified as domains relevant to CKD-associated anemia.

METHODS

A total of 204 patients aged 18-80 years were included in the analyses that included internal consistency (Cronbach's alpha), test-retest reliability (intraclass correlation coefficients [ICCs]), convergent and known-groups validity, responsiveness, and estimates of important change.

RESULTS

Both the SF-36 and the FACT-An had strong psychometric properties with high internal consistency (Cronbach's alpha: 0.69-0.93 and 0.79-0.95), and test-retest reliability (ICCs: 0.64-0.83 and 0.72-0.88). Convergent validity, measured by correlation coefficients between similar concepts in SF-36 and FACT-An, ranged from 0.52 to 0.77. Correlations with hemoglobin (Hb) levels were modest at baseline; by Week 9, the correlations with Hb were somewhat higher, r = 0.23 (p < 0.05) for SF-36 Vitality, r = 0.22 (p < 0.05) for FACT-An Total, r = 0.26 (p < 0.001) for FACT-Fatigue and r = 0.22 (p < 0.01) for Anemia. Correlations with Hb at Week 13/17 were r = 0.28 (p < 0.001) for SF-36 Vitality and r = 0.25 (p < 0.05) for Role Physical; FACT-An Total correlation was r = 0.33 (p < 0.0001), Anemia was r = 0.28 (p < 0.001), and Fatigue was r = 0.30 (p < 0.001). The SF-36 domains and Component Summary scores (p < 0.05-p < 0.0001) demonstrated ability to detect change. For the FACT-An, significant differences (p < 0.05-p < 0.0001) were observed between responder and non-responder change scores: important change score estimates ranged from 2 to 4 for Vitality and 2-3 for Physical functioning. Important change scores were also estimated for the FACT-An Total score (6-9), the Anemia (3-5), and Fatigue subscale (2-4).

CONCLUSIONS

Both the SF-36 Vitality and Physical function scales and the FACT-An Total, Fatigue and Anemia scales, are reliable and valid measures for assessing health-related quality of life in anemia associated with CKD.

Influence of Major Coping Strategies on Treatment Non-adherence and Severity of Comorbid Conditions in Hemodialysis Patients

BACKGROUND

Non-adherence and comorbidities are prevalent among hemodialysis patients and are associated with increased mortality and financial burden. We aimed to investigate the influence of major coping strategies (CSs) on non-adherence and comorbidities in hemodialysis patients.

METHODS

A total of 49 patients were enrolled. We collected participant data including CS measured by a Korean version of the ways of coping questionnaire (K-WCQ), comorbidities measured by age-adjusted Charlson comorbidity index (CCI), and adherence measured by the 8-item Morisky medication adherence scale (MMAS-8).

RESULTS

Regarding major CS, 61.2% of participants reported use of support-seeking CS (SUP group), 14.3% reported use of problem-focused CS (PRO group), and 24.5% reported use of hopeful-thinking CS (HOP group). The mean MMAS-8 score was higher in the PRO group than in the HOP group (P = 0.024). The mean CCI score was lower in the PRO group than in the HOP group (P = 0.017). In the HOP group, the severity of somatic symptoms was positively correlated with the scores for the emotion-focused CS subscale (r = 0.39, P = 0.029) and the hopeful-thinking CS subscale (r = 0.38, P = 0.036) of the K-WCQ. The level of life satisfaction positively correlated with the score for the problem-focused CS subscale in the HOP group (r = 0.40, P = 0.027).

CONCLUSION

We should pay more attention to the CSs of hemodialysis patients and provide interventions that promote problem-focused CSs, especially for nonadherent patients with high comorbidity rates who mainly use a hopeful-thinking CS.

Knowledge: disease process in patients undergoing hemodialysis

OBJECTIVES

To identify the relationship between socioeconomic variables and nursing outcome indicators Knowledge: disease process.

METHODS

This is a cross-sectional study involving 51 patients undergoing hemodialysis at a public nephrology hospital in a city in northeastern Brazil. A questionnaire covering sociodemographic information and the 15 nursing outcome indicators Knowledge: disease process.

RESULTS

A statistically significant but weak correlation was found between age and the indicators Specific process of the disease (r=-0.28), Cause and contributing factors (r=-0.36), Signs and symptoms of the disease (r=0.30), Signs and symptoms of complications of the disease (r=-0.37), Precautions to prevent complications of the disease (r=-0.35); number of years of schooling and the indicators Specific process of the disease (r=0.29), Cause and contributing factors (r=0.28), and Signs and symptoms of the disease (r=0.34). There were significant and moderate correlations of age with the indicator Psychosocial effect of the disease in the individual (r=-0.41), in the family (r=-0.44) and benefits of disease control (r=-0.48). Sex was related only to the indicator Specific process of the disease (p=0.03).

CONCLUSIONS

There was no relationship between some indicators of the outcome Knowledge: disease process with the sociodemographic variables in patients undergoing hemodialysis, a fact that underscores the importance of implementing nursing interventions that take into account the particularities of the individuals.

Neurocognitive and Educational Outcomes in Children and Adolescents with CKD: A Systematic Review and Meta-Analysis

BACKGROUND AND OBJECTIVES

Poor cognition can affect educational attainment, but the extent of neurocognitive impairment in children with CKD is not well understood. This systematic review assessed global and domain-specific cognition and academic skills in children with CKD and whether these outcomes varied with CKD stage.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Electronic databases were searched for observational studies of children with CKD ages 21 years old or younger that assessed neurocognitive or educational outcomes. Risk of bias was assessed using a modified Newcastle-Ottawa scale. We used random effects models and expressed the estimates as mean differences with 95% confidence intervals stratified by CKD stage.

RESULTS

Thirty-four studies (25 cross-sectional, n=2095; nine cohort, n=991) were included. The overall risk of bias was high because of selection and measurement biases. The global cognition (full-scale intelligence quotient) of children with CKD was classified as low average. Compared with the general population, the mean differences (95% confidence intervals) in full-scale intelligence quotient were -10.5 (95% confidence interval, -13.2 to -7.72; all CKD stages, n=758), -9.39 (95% confidence interval, -12.6 to -6.18; mild to moderate stage CKD, n=582), -16.2 (95% confidence interval, -33.2 to 0.86; dialysis, n=23), and -11.2 (95% confidence interval, -17.8 to -4.50; transplant, n=153). Direct comparisons showed that children with mild to moderate stage CKD and kidney transplants scored 11.2 (95% confidence interval, 2.98 to 19.4) and 10.1 (95% confidence interval, -1.81 to 22.0) full-scale intelligence quotient points higher than children on dialysis. Children with CKD also had lower scores than the general population in executive function and memory (verbal and visual) domains. Compared with children without CKD, the mean differences in academic skills (n=518) ranged from -15.7 to -1.22 for mathematics, from -9.04 to -0.17 for reading, and from -14.2 to 2.53 for spelling.

CONCLUSIONS

Children with CKD may have low-average cognition compared with the general population, with mild deficits observed across academic skills, executive function, and visual and verbal memory. Limited evidence suggests that children on dialysis may be at greatest risk compared with children with mild to moderate stage CKD and transplant recipients.
