Quality of life and mental health in hemodialysis and peritoneal dialysis patients: the role of health beliefs

Hope, quality of life, and psychological distress in patients on peritoneal dialysis: A cross-sectional study

Hope is a goal-directed thought that reflects the sense of control over uncertainties and can promote adjustment to chronic illness. This study aimed to assess the level of hope among patients on peritoneal dialysis and evaluate the association of hope with health-related quality of life and psychological distress. This cross-sectional study included 134 Chinese patients receiving peritoneal dialysis in Hong Kong. Patients' level of hope was assessed using the Adult Trait Hope Scale. Participants who were employed, had a higher income, and received automated peritoneal dialysis reported a higher hope score. Hope was found to have significant correlations with age and social support. A higher hope score was associated with better mental well-being and less severe depressive symptoms. Specific relationships between agency/pathway thinking and these outcomes were identified. The patient subgroups at risk for losing hope need to be identified and received early interventions to prevent adverse outcomes.

Insomnia and common mental disorder among patients with pre-existing chronic non-communicable diseases in southern Ethiopia: a survey during COVID-19 pandemic

Background

COVID-19 has been causing significant mental health problems and other health-related issues. Despite the fact that COVID-19 has a significant impact on chronic disease patients, there is scant research on insomnia, common mental health disorders (CMD), and their associated factors among chronic disease patients.

Objective

The purpose of this study was to assess the prevalence of insomnia and common mental disorders (CMD) and their associated factors among patients with pre-existing chronic NCDs in Sidama, southern Ethiopia.

Methods

A multicenter cross-sectional study was undertaken between June 1 and September 1, 2021. The study included 633 participants. CMD and insomnia were assessed using a 20-item Self-Reported Questionnaire (SRQ-20) and a 7-item Insomnia Severity Index (ISI) scale, respectively. To describe the various variables, descriptive statistics were used. We performed multivariable logistic regression analysis to identify independent factors associated with CMD and insomnia. A value of p < 0.05 was considered statistically significant at a 95% confidence interval.

Results

The prevalence of insomnia and CMD was found to be 39.3% and 46.8%, respectively. Being merchant (AOR = 0.33; 95% CI = 0.13, 0.82), having a diagnosis of diabetes mellitus (AOR = 1.89; 95% CI = 1.04, 3.46), comorbid diagnosis (AOR = 3.96; 95% CI = 2.27, 6.89), low social support (poor (AOR = 3.37; 95% CI = 1.51, 7.57) and moderate (AOR = 3.13; 95% CI = 1.46, 6.69)), symptoms of insomnia (AOR = 12.08; 95% CI = 7.41, 19.72) and poor quality of life (QOL) (AOR = 1.67; 95% CI = 1.04, 2.72) were independent predictors of CMD. We also found out that, having cardiovascular disorders (CVDs) (AOR = 2.48; 95% CI = 1.18, 5.19), CMD (AOR = 12.09; 95% CI = 7.46, 19.61), and poor QOL (AOR = 2.04; 95% CI = 1.27, 3.26) were significantly associated with insomnia symptoms.

Conclusion

Our study suggests that substantially high prevalence of CMD and insomnia. Significant association between CMD and occupation, diagnosis, comorbidity, social support, insomnia, and QOL were found. We also revealed that having CVDs, CMD, and poor QOL were significantly associated with insomnia symptoms. Therefore, dealing with the mental health problems of patients with chronic NCDs is an essential component of public health intervention during the COVID-19 pandemic.

A survey study of adults with chronic conditions: Examining the correlation between patient activation and health locus of control

OBJECTIVES

This study aimed to examine (1) the association between patient activation (PA), health locus of control (HLOC), sociodemographic and clinical factors, and (2) the effect of HLOC dimensions, sociodemographic and clinical factors on PA.

METHODS

Three hundred U.S. adults, with at least one chronic condition (CC) were recruited through Amazon Mechanical Turk and completed an online survey which included sociodemographic questions, the Patient Activation Measure^® - 10, and the Multidimensional Locus of Control (MHLC) - Form B. Statistical analyses, including descriptive, correlation, and multiple linear regression, were conducted using IBM SPSS v25.

RESULTS

Of the 300 participants, more than half were male (66.3%), White (70.7%), with at least a college degree (76.0%), and employed full-time (79.0%). The average PA score was 68.8 ± 14.5. Multiple linear regression indicated that participants who reported they were Black, retired, with a greater number of CCs, and with higher scores in Chance MHLC had higher PA, while participants with higher scores in Internal MHLC, were unemployed and reported to have been affected by COVID-19-related worry or fear to manage their CC, had lower PA.

DISCUSSION

HLOC dimensions should be addressed concurrently with PA for patients with CCs, thus adding to a more patient-centered clinical approach.

Investigation of Anxiety and Health Locus of Control in Patients Undergoing Hemodialysis

INTRODUCTION

Hemodialysis is the most frequent treatment modality for End-Stage Renal Disease (ESRD). However, a number of limitations and modifications accompany this treatment, affecting people's physical and psychological well-being and increasing anxiety symptoms. The aim of this study was to investigate the level of anxiety and health locus of control among dialysis patients.

METHODOLOGY

One hundred and five patients on hemodialysis treatment completed a questionnaire with demographic characteristics, the State-Trait Anxiety Inventory and the Multidisciplinary Health Locus of Control Scale.

RESULTS

Women had significantly higher levels of state anxiety than men (p = 0.019). Similarly, patients with primary school education had significantly higher trait and total anxiety levels than those with technological education (p = 0.002 and p = 0.033, respectively). Widowed patients exhibited significantly higher state, trait, and total anxiety levels than married (p = 0.032, p = 0.012, and p = 0.012, respectively). Participants who did not do any kind of exercise had significantly higher level of state, trait, and total anxiety than those who did (p = 0.011, p = 0.015, and p = 0.006, respectively). Respondents who did not have any self-care skills had significantly higher level of state, trait, and total anxiety than those who had (p = 0.011, p = 0.015, and p = 0.006, respectively). State, trait, and total anxiety levels were significantly (p ≤ 0.05) correlated negatively with internal locus of control and positively with "chance" locus of control scale.

CONCLUSIONS

Hemodialysis patients had increased anxiety symptoms and believed that others had control over their health to a greater extent. Renal professionals need to apply effective interventions to dialysis patients in order to help them gain a better sense of control over their health and reduce anxiety symptoms.

Impact of personalized nutritional intervention on nutritional status and quality of life of maintenance hemodialysis patients with protein energy wasting

BACKGROUND: Protein energy wasting (PEW) is a common multifactorial problem affecting maintenance hemodialysis (MHD) patients. OBJECTIVES: We aimed to explore the impact of personalized nutritional intervention on nutritional status and quality of life (QOL) in MHD patients. METHODS: Interventional study included 18 MHD patients suffering from PEW. They were subjected to personalized nutritional intervention for 6 months according to Kidney Disease Outcomes Quality Initiative (KDOQI) Clinical Practice Guidelines (2000). QOL was evaluated by using the Kidney Disease Quality of Life (36 KDQOL-36). Nutritional status and QOL of those patients were re-assessed after 6 months and compared to those at the baseline. RESULTS: Fourteen patients completed six months of the study. Following such intervention, half of these patients became no longer suffering from PEW (responder group). Most of the nutritional and QOL data improved in the responder in contrary to the non-responder group of patients. The baseline level of parathyroid hormone (PTH) was significantly higher but physical health was significantly lower in non-responder than responder groups. CONCLUSIONS: Implementation of an internationally acknowledged nutritional program could improve the nutritional status and QOL of MHD patients with PEW. Moreover, PTH level, and physical health of the studied patients could contribute to the positive response to nutritional intervention.

The Impact of the COVID-19 Pandemic on Psychological Health and Insomnia among People with Chronic Diseases

The outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic highlighted the serious problems of health care systems but also threatened the mental and physical health of patients worldwide. The goal of this study was to assess psychological health and insomnia in people with chronic diseases in the time of elevated stress associated with the pandemic. The study involved 879 people from Zachodniopomorskie province in Poland. Each participant provided basic demographic data, data on symptoms of insomnia, depression, anxiety and information on concomitant diseases such as hypertension, diabetes mellitus, coronary heart disease, heart failure, dyslipidemia, chronic obstructive pulmonary disease, Hashimoto’s disease and smoking cigarettes. Chronic diseases included in this study showed a strong correlation between Hashimoto’s disease and increase scores according to the Insomnia Severity Index (ISI, r = 0.797, p < 0.001), the Generalized Anxiety Disorder scale (GAD-7, r = 0.766, p < 0.001) and the Patient Health Questionnaire (PHQ-9, r = 0.767, p < 0.001). After the results were corrected for age, gender, diagnosed hypertension, dyslipidemia and cigarette smoking, it was confirmed that the diagnosis of Hashimoto’s disease was associated with an increased risk of anxiety (odds ratio (OR) = 2.225; p < 0.001), depression (OR = 2.518; p < 0.001) and insomnia (OR = 3.530; p < 0.001). Our study showed that during the SARS-CoV-2 pandemic patients with Hashimoto’s disease show a higher risk of insomnia, anxiety and depression.

Quality of life, depression, and anxiety of patients undergoing hemodialysis: Significant role of acceptance of the illness

OBJECTIVE

Routine dialysis is stressful. It has the possibility of leading to depression and anxiety and also reducing patients' quality of life. Despite these significant consequences, these comorbidities have been rarely studied among Indonesian patients. This study aims to examine the rate of depression, anxiety, and the role of acceptance of their illness on patients' quality of life.

METHOD

A total of 213 patients undergoing hemodialysis in three general hospitals in Aceh, Indonesia, were included in the study. The presence of depression, anxiety, and the quality of life of each patient was assessed using the hospital anxiety and depression scale and WHO quality of life-BREF questionnaires.

RESULTS

The prevalence of depression and anxiety was 46% and 30.5%, respectively. Depression was only associated with the presence of anxiety and the duration of hemodialysis. Anxiety was negatively associated with quality of life but positively associated with depression and the prescription of an anxiolytic. Overall quality of life was associated with age, body mass index, the presence of anxiety, and acceptance of the illness. Acceptance of the illness was also independently associated with almost every domain of patients' quality of life.

CONCLUSIONS

The rates of depression and anxiety among patients undergoing hemodialysis in the current study setting are relatively similar to the rates in other settings. Patients' acceptance of their illnesses is significantly associated with the occurrence of anxiety and quality of life. Therefore, health practitioners should help patients accept their illnesses and the administration of regular hemodialysis.

Health literacy and quality of life among Iranian pregnant women: The mediating role of health locus of control

Background: Main health challenge of the 21st century is improving quality of life (QoL). This study aimed to investigate the mediating role of health locus of control (HLC) between health literacy and QoL among Iranian pregnant women. Methods: In this cross sectional survey, 400 pregnant women referred to the community health centers of Gonabad, Iran, and completed the demographic, health literacy, QoL, and multidimensional HLC questionnaires during 2015-2016. Descriptive statistics and structural equation modeling were conducted using SPSS 22.0 version and AMOS 24.0 software. Results: The findings showed that health literacy has a significant positive effect on the physical (β= 0.54, p< 0.001) and mental (β= 0.57, p< 0.001) health. Also, it has a significant positive effect on internal subscale (β= 0.42, p< 0.001) and a significant negative effect on the chance (β= -0.51, p< 0.001) and powerful others (β= -0.33, p< 0.001) subscale of HLC. From HLC subscales, internal HLC had a significant positive effect on physical (β= 0.26, p< 0.001) and mental (β= 0.12, p= 0.010) health, while the effects of chance and powerful others on QoL dimensions were not significant. The findings indicated that internal HLC is a partial mediator between health literacy and physical dimension of QoL. Conclusion: The results indicate that health literacy can be considered as an effective factor in HLC orientations and can improve QoL. This reflects the need for more attention on health literacy and the recognition of the type of HLC beliefs, especially the internal belief in health promotion programs for pregnant women.

Association between Dialysis Adequacy and Cognition in Patients with Peritoneal Dialysis

OBJECTIVE

Cognition of peritoneal dialysis patients is influenced by various factors including dialysis adequacy such as fractional urea clearance (Kt/V) and relative overhydration (RelOH). This study aimed to discover the potential contribution of dialysis adequacy to cognitive function in patients undergoing peritoneal dialysis.

METHODS

Fifty-nine patients undergoing peritoneal dialysis were recruited. Demographic information, comorbidities, and clinical lab findings were retrospectively collected, and dialysis adequacy was determined by the Kt/V and RelOH calculation. Cognition and depression were measured with Digit Symbol Substitution Test, Hopkins Verbal Learning Test, Wechsler memory scale (spatial span), Wisconsin Card Sorting Test, and Beck's depression inventory. Partial correlation test was used to explore the correlation of dialysis adequacy with cognitive function.

RESULTS

RelOH showed significant correlation with some of the Wisconsin Card Sorting test results. The categories achieved showed negative correlation (r=-0.32, p=0.02) and trials to complete first category showed positive correlation (r=0.31, p=0.02) with RelOH. Other tasks showed no significant correlation with RelOH. Kt/V.

CONCLUSION

Our study demonstrates that peritoneal dialysis adequacy, measured by RelOH, seems to be significantly correlated with the occurrence of cognitive impairment. The outcome suggests that RelOH may have the potential to clarify the role of cognitive impairment in peritoneal dialysis patients.

Evaluation of Mental Health Factors among People with Systemic Lupus Erythematosus during the SARS-CoV-2 Pandemic

There are considerable psychological and psychiatric consequences of the pandemic. Researchers have started to take into account the real or perceived sense of social threats that may be expressed, such as anxiety, depression, and sleep disorders. However, analyses on pandemic-related anxiety, depression, and sleep disorders mostly rarely addresses the situation of people with autoimmune diseases. Therefore, the aim of this study was to assess the mental health factors among people with systemic lupus erythematosus by quantifying the severity of anxiety, depression, and sleep disorders during the SARS-CoV-2 pandemic. In total, 723 people took part in the study. The study group consisted of 134 individuals with a systemic lupus erythematosus. The control group consisted of 589 people without systemic lupus erythematosus. The regression adjusted by age, gender, and diagnosis of other chronic diseases showed individuals with systemic lupus erythematosus were at a much higher risk of elevated symptoms of anxiety on the GAD-7 scale (OR = 3.683; p < 0.001), depression on the PHQ-9 scale (OR = 4.183; p < 0.001), and sleep disorders on the Insomnia Severity Index (ISI) scale (OR = 6.781; p < 0.001). Therefore, the mental health of patients with systemic lupus erythematosus in the times of the SARS-CoV-2 pandemic is not only an extremely important medical problem but also a social one and must require special attention.

Health-Related Quality of Life in Home Dialysis Patients Compared to In-Center Hemodialysis Patients: A Systematic Review and Meta-analysis

RATIONALE & OBJECTIVE

Dialysis patients judge health-related quality of life (HRQoL) as an essential outcome. Remarkably, little is known about HRQoL differences between home dialysis and in-center hemodialysis (HD) patients worldwide.

STUDY DESIGN

Systematic review and meta-analysis.

SETTING & STUDY POPULATIONS

Search strategies were performed on the Cochrane Library, Pubmed, and EMBASE databases between 2007 and 2019. Home dialysis was defined as both peritoneal dialysis and home HD.

SELECTION CRITERIA FOR STUDIES

Randomized controlled trials and observational studies that compared HRQoL in home dialysis patients versus in-center HD patients.

DATA EXTRACTION

The data extracted by 2 authors included HRQoL scores of different questionnaires, dialysis modality, and subcontinent.

ANALYTICAL APPROACH

Data were pooled using a random-effects model and results were expressed as standardized mean difference (SMD) with 95% CIs. Heterogeneity was explored using subgroup analyses.

RESULTS

Forty-six articles reporting on 41 study populations were identified. Most studies were cross-sectional in design (90%), conducted on peritoneal dialysis patients (95%), and used the 12-item or 36-item Short-Form Health Survey questionnaires (83%). More than half the studies showed moderate or high risk of bias. Pooled analysis of 4,158 home dialysis patients and 7,854 in-center HD patients showed marginally better physical HRQoL scores in home dialysis patients compared with in-center HD patients (SMD, 0.14; 95% CI, 0.04 to 0.24), although heterogeneity was high (I 2>80%). In a subgroup analysis, Western European home dialysis patients had higher physical HRQoL scores (SMD, 0.39; 95% CI, 0.17 to 0.61), while home dialysis patients from Latin America had lower physical scores (SMD, -0.20; 95% CI, -0.28 to -0.12). Mental HRQoL showed no difference in all analyses.

LIMITATIONS

No randomized controlled trials were found and high heterogeneity among studies existed.

CONCLUSIONS

Although pooled data showed marginally better physical HRQoL for home dialysis patients, the quality of design of the included studies was poor. Large prospective studies with adequate adjustments for confounders are necessary to establish whether home dialysis results in better HRQoL.

Self-Management Behaviors in Obese Patients Undergoing Surgery Based on General and Specific Adherence Scales

BACKGROUND

Adherence has been defined as the degree to which a patient's voluntary behavior corresponds with the clinical recommendations of health care providers. The aim of this study was to predict self-management behaviors in obese patients undergoing surgery based on general and specific adherence scales.

METHODS

All obese patients who underwent bariatric surgery in Ghadir Mother and Child Hospital, Shiraz, Iran from April 2017 to September 2017 were enrolled. By using available sampling method, 201 patients with BMI above 35 (36.43±35.11) and in the age range of18-65 years (13.38±80/5) were selected. A questionnaire containing general adherence scale (GAS), specific adherence scale (SAS) and post-surgery self-management behaviors questionnaire (BSSQ) was completed by all patients.

RESULTS

The general and specific adherence scales were significant predictors for self-management behaviors after surgery, and positive relation was found for general and specific adherence scales with self-management behaviors.

CONCLUSION

Self-management behaviors regarding eating behaviors, supplements, fruits, vegetables, grains, protein and fluid intake, physical activity, dumping syndrome management have significant relationship with general and specific adherence scales. So increasing knowledge, skills, motivation, self-confidence, self-efficacy and self-monitoring of obese patients after surgery seem necessary.

Health-promoting Lifestyle, Illness Control Beliefs and Well-being of the Obese Diabetic Women

The study examines the role of health-promoting lifestyle and illness control beliefs in well-being of obese diabetic women. Measures of illness control belief, health-promoting lifestyle and obesity-related well-being were given to 100 obese diabetic women selected from outdoors of hospitals in Varanasi. Analysis revealed patients’ stronger belief in ‘doctor-control’ and ‘supernatural-control’ than ‘self-control’ of the disease. Nutrition, interpersonal relations, physical activity and stress management were given more importance in health promotion than spiritual growth-related practices. Belief in ‘self-control’ and ‘doctor-control’ of disease was negatively correlated with ‘psychosocial discomfort’, ‘physical discomfort’ and ‘psychosocial impact’ aspects of obesity, whereas ‘supernatural-control’ showed positive relationship with all aspects. All components of ‘health-promoting lifestyle’ were negatively correlated with ‘physical discomfort’, ‘psychosocial discomfort’ and ‘psychosocial impact’ aspects of obesity. Multiple regression analysis brought out ‘self-control’, ‘supernatural-control’, ‘health responsibility’, ‘physical activity’ and ‘stress management’ as significant predictors of ‘well-being’ of the obese diabetic women.

Relating Health Locus of Control to Health Care Use, Adherence, and Transition Readiness Among Youths With Chronic Conditions, North Carolina, 2015

Introduction

Health locus of control refers to the belief that health is in one’s control (internal control) or is not in one’s control (external control). Among adults, external locus of control is associated with negative health outcomes, whereas internal locus of control is associated with favorable outcomes. Few studies examined these associations among youths. The objective of our study was to determine how locus of control relates to health care use, medication adherence, missed school, and readiness for transition to adult medical care for youths with chronic conditions.

Methods

Participants at a camp for youths aged 6 to 17 years with chronic health conditions completed a survey measuring locus of control, readiness for transition to adult care, and medication adherence. Their parents completed a separate part of the survey about health care use and missed school days in the past year.

Results

A total of 163 youths completed the survey (78.5% white; 52.1% female; mean age, 12.3 y). Internal locus of control (β = 0.196; P = .013) and external Doctor locus of control with doctors controlling disease (β = 0.181; P = .025) were positively associated with transition readiness. External control by chance or with others controlling disease was negatively associated with transition readiness (β = −0.248; P = .002) and positively associated with emergency department visits (β = 0.225; P = .004) and with number of hospital inpatient nights at hospital (β = 0.166; P = .04).

Conclusion

Adolescents with external control of their health by chance or by other people are at increased risk for negative health outcomes and may fail to develop the self-management skills needed for successful transitioning to adult care. Future studies should examine effects of changes in locus of control on health outcomes among youths.

The anticipated and the lived experience of home and in-centre haemodialysis: Is there a disconnect?

This qualitative study aimed to explore home haemodialysis and in-centre haemodialysis patients’ experience, to illuminate barriers and facilitators in the uptake and maintenance of home haemodialysis. Thirty-two semi-structured interviews with patients receiving home haemodialysis or in-centre haemodialysis were analysed using framework analysis. Four themes emerged: ‘perceptions of self’; ‘impact of haemodialysis on family’; ‘perceived advantages and disadvantages of home haemodialysis and in-centre haemodialysis’ and ‘practical issues and negotiating haemodialysis’. The lived experience of home haemodialysis was in contrast to the lived experience of in-centre haemodialysis and to the anticipated experience of home haemodialysis, highlighting patient factors that contributed to under-usage of home haemodialysis.

'An exploration of the health beliefs of Chinese nurses' and nurse academics' health beliefs: A Q-methodology study'

Q-methodology was used to investigate the health beliefs of Chinese clinical nurses and nurse academics. Twenty-eight participants from one hospital and nursing school in China were involved. The four stages of this study included: (i) concourse development from literature review, Internet searches, and key informant interviews; (ii) A pilot study to develop the Q-sample from the concourse; (iii) participants sorted the Q-sample statements along a continuum of preference (Q-sorting); and (iv) PQ data analysis using principal component analysis and varimax rotation. Five viewpoints were revealed: (i) factor 1--health management and the importance of evidence; (ii) factor 2--challenging local cultural belief, and Eastern and Western influences; (iii) factor 3--commonsense; (iv) factor 4--health and clinical practice; and (v) factor 5--health and nursing education. This study presents a need for nurses and nurse academics to think critically, examine their long-held health beliefs, and promote the use of evidence-based practice.

Psychological predictors for health-related quality of life and disability in persons with chronic obstructive pulmonary disease (COPD)

OBJECTIVE

Individuals with chronic obstructive pulmonary disease (COPD) exhibit low physical and mental health-related quality of life (HRQL) and high susceptibility to disability. We investigated the influence of psychological factors on HRQL and disability in COPD individuals recruited from the general population. In line with Leventhal's common sense model, we expected psychological factors to be associated with HRQL and disability even after controlling for medical status.

METHODS

Individuals with COPD (n = 502; 59.7 years old; GOLD grades were I: 3%, II: 17%, III: 34%, IV: 46%) were assessed through an online survey administered via COPD patient organisations in Germany. Individuals filled in the Short Form Health Survey (SF-12), COPD Assessment Test, Patient Health Questionnaire (modules: GAD-2, PHQ-15, PHQ-9), Brief Illness Perception Questionnaire, a questionnaire that assesses causal illness attributions, and the internal illness-related locus of control scale of the 'KKG questionnaire for the assessment of control beliefs about illness and health'. Multiple linear regressions were calculated.

RESULTS

The investigated factors explained high variances (disability = 56%, physical HRQL = 28%, mental HRQL = 63%, p ≤ .001). Better mental health, more optimistic illness perceptions, attribution to psychological causes, and stronger internal locus of control were associated with lower disability and better HRQL. Comorbid somatic symptoms contributed to high disability and low quality of life.

CONCLUSION

Psychological factors, such as illness perception, attribution and internal locus of control, were associated with disability and HRQL. These factors should be considered when designing treatments for individuals with COPD, and adequate interventions should be provided to enhance illness understanding and self-management skills.

Investigation of Anxiety and Depression in Patients with Chronic Diseases

The health of an individual depends on both his/her physical and psychological condition. In recent years it has been observed that chronic patients have frequently an affected psycho-emotional state. The purpose of this study is to investigate anxiety and depression in patients with chronic diseases and the correlation of the results with daily physical activity levels and individual health levels, as well comorbidity. This study included patients with chronic diseases that were treated in a local general hospital or were visiting often outpatient clinics of the same hospital due to their condition. The sample in this particular study included 204 patients; 118 of them were women and 86 men. From the total sample that participated in our research, 118 (57.8%) were females and the majority of the participants were secondary/basic education graduates (67%), married (71%), living in urban areas (53%). Hypertension was the most frequent chronic disease in our sample, followed by hypercholesterolemia and diabetes mellitus. Comparing the occurrence of depression and anxiety symptoms in both questionnaires in relation to the expected frequency in the general population, significant levels of depression and anxiety symptoms were recorded. Taking into consideration the findings of this research, anxiety and depression symptoms can have profound effects regarding the control of chronic diseases, the patients' quality of life and their general health.

Predictors of quality of life in patients with end-stage renal disease on hemodialysis

Background

Assessment of quality of life (QOL) of end-stage renal disease (ESRD) patients (physical, mental, and social well-being) has become an essential tool to develop better plans of care. Objective of this study is to determine which demographic and biochemical parameters correlate with the QOL scores in patients with ESRD on hemodialysis (HD) using Kidney Disease QOL-36 surveys (KDQOL).

Methods

A retrospective chart review of all ESRD patients who underwent HD at an outpatient center. The five components of the KDQOL were the primary end points of this study (burden of kidney disease, symptoms and problems, effects of kidney disease on daily life, mental component survey, and physical component survey). Scores were grouped into three categories (below average, average, and above average). In addition to demographics (age, sex, and race), the independent variables such as weight gain, number of years on dialysis, urea reduction ratio, calcium, phosphorus, parathyroid hormone, albumin, and hemoglobin in the serum were collected. Chi-square analysis for dependent variables and the nominal independent variables was used, and analysis of variance analysis was used for continuous independent variables. Ordinal regression using PLUM (polytomous universal model) method was used to weigh out possible effects of confounders.

Results

The cohort size was 111 patients. Mean age was 61.8 (±15.5) years; there were more males than females (64.9% vs 35.1%), the mean time-on-dialysis at the time of the study was 4.3 (4.8) years. Approximately two-thirds of the responses on all five domains of the questionnaire ranked average when compared to the national numbers. The remainders were split between above average (20.6%) and below average (13.4%). In our cohort, no relationships were statistically significant between the five dependent variables of interest and the independent variables by chi-square- and t-test analyses. This was further confirmed by regression analysis. Of note, sex carried the strongest statistical significance (with a P-value of 0.16) as a predictor of “the burden of kidney disease on daily life” in ordinal regression.

Conclusion

Prior studies have shown variables such as serum phosphate level, intradialytic weight gain, and dialysis adequacy are associated with lower KDQOL scores; however, this was not evident in our analysis likely due to smaller sample size. Larger size studies are required to better understand the predictors of QOL in ESRD patients on HD.

Patterns of health-related quality of life and associated factors in Chinese patients undergoing haemodialysis

BACKGROUND

Haemodialysis (HD) is a life-saving but burdensome therapy for patients with end-stage renal disease (ESRD) which can have a detrimental impact on patients' quality of life and outcomes. There is currently little data on the health related quality of life (HRQOL) of Chinese ESRD patients undergoing HD and this study sought to examine the patterns of HRQOL and its associated factors within this population, as well as in comparison with the general local population.

METHODS

A cross-sectional study of 244 ESRD patients receiving HD in the hospital and in the community in Hong Kong was conducted using the Short Form-12 Health Survey version 2 (SF-12v2). All study subjects were one-to-one matched with subjects in a Hong Kong general population database by sex and exact age. Independent t-tests were performed to compare the mean SF-12v2 scores between HD patients and the general population, followed by one-way analysis of variance with post hoc Tukey's HSD tests to compare community-based haemodialysis, hospital-based haemodialysis and the general population. Multiple linear regressions were used to identify the factors (socio-demographic, clinical characteristics and comorbidities) associated with the HRQOL scores of ESRD patients receiving HD.

RESULTS

The SF-12v2 Physical Functioning, Role Physical, Bodily Pain, General Health and Physical Component Summary scores of HD patients were significantly lower than the age-sex adjusted general population. However, the SF-12v2 Mental Health and Mental Component Summary scores of HD patients were significantly higher than the corresponding general population. Poorer HRQOL was associated with being female, smoking, unemployment and hospital-based haemodialysis.

CONCLUSIONS

HD patients had substantially poorer physical HRQOL but better mental HRQOL than the age-sex adjusted general population. Patients receiving HD in the community setting had better HRQOL. Reasons for these observations will need to be further investigated. Those patients who are female, smokers and unemployed may warrant more attention as their poorer HRQOL may be associated with poorer outcomes.

Management of Pain and Quality of Life in Patients with Chronic Kidney Disease Undergoing Hemodialysis

An important dimension that influences the quality of life of hemodialysis patients is the pain they experience. Quality of life and self-efficacy in pain can play an important role in chronic kidney disease and treatment outcomes. The purpose of the study was to examine self-efficacy in pain and quality of life among patients with end stage renal disease undergoing hemodialysis. Between April 2013 and June 2013, 224 hemodialysis patients completed the Missoula-VITAS Quality of Life Index-15 and the Pain Self-Efficacy Questionnaire. The study was conducted in four dialysis units in hospitals of the Peloponnese region. Sociodemographic data of patients and their individual medical history were recorded. Statistical analysis was performed using SPSS version 19. The more effective the self-efficacy in pain, the lower the quality of life enjoyed by hemodialysis patients. The majority of respondents described the overall quality of life as "moderate," while the self-efficacy in pain depended on comorbidity or complications that accompany the process of hemodialysis. The findings of this study can be used in the development and improvement of health services for the management of patients. Healthcare professionals should understand the concerns and treat the symptoms of patients that affect quality of life, providing thereby holistic health care.

Enhanced H-filter based on Fåhræus-Lindqvist effect for efficient and robust dialysis without membrane

A novel microfluidic device for highly efficient and robust dialysis without membrane is highly desired for the development of portable or wearable microdialyzer. Here we report an enhanced H-filter with pillar array based on Fåhræus-Lindqvist effect (F-L effect) for highly efficient and robust membraneless dialysis of simplified blood for the first time. The H-filter employs two fluids laminarly flowing in the microchannel for continuously membraneless dialysis. With pillar array in the microchannel, the two laminar flows, with one containing blood cells and small molecules and another containing dialyzate solution, can form a cell-free layer at the interface as selective zones for separation. This provides enhanced mixing yet extremely low shear for extraction of small molecules from the blood-cell-containing flow into the dialyzate flow, resulting in robust separation with reduced cell loss and improved efficiency. We demonstrate this by first using Chlorella pyrenoidosa as model cells to quantitatively study the separation performances, and then using simplified human blood for dialysis. The advanced H-filter, with highly efficient and robust performance for membraneless dialysis, shows great potential as promising candidate for rapid blood analysis/separation, and as fundamental structure for portable dialyzer.

THE IMPACT OF SOCIOECONOMIC FACTORS ON QUALITY OF LIFE OF PATIENTS WITH CHRONIC KIDNEY DISEASE IN GREECE

BACKGROUND

Quality of Life (QoL) is often poor in people undergoing dialysis and this sometimes contributes to the high rate of morbidity and mortality. The aim of our study is to assess the QoL of patients on haemodialysis in Greece and discuss the socio-demographic factors that affect QoL in this period of financial crisis.

DESIGN/PATIENTS

Patients with CKD not on dialysis, plus those undergoing Haemodialysis (HD) and Peritoneal Dialysis (PD) were invited to complete the SF-36 questionnaire electronically, supervised by a trained nurse. Patients were asked about their marital status, education level and monthly household income. Additionally, patients were requested to comment on their subjective financial difficulties.

RESULTS

A total of 172 patients were enrolled in the study, 39 of them were undergoing PD, 90 on HD and 43 had CKD. Among those with CKD, on HD and PD, 9.3%, 17.8% and 23.1%, respectively, had 'some/a lot' difficulties in copying with financial problems. The physical component summary score was significant lower in HD, while the summary score of the mental component showed no differences between the groups. In multiple linear regression analysis, age and dialysis had significantly negative correlations with physical functioning scores. Those who were divorced or widowed tended to perform worse in physical scores compared with those who were married. Mental scores were affected only by coping with financial difficulties.

CONCLUSIONS

In general terms, people with CKD patients present with a poor QoL. Apart from the burden of the renal disease per se, social and economic factors (divorce, financial difficulties) seem to aggravate their status, especially in this period of financial crisis.

The Impact of Kt/V Urea-Based Dialysis Adequacy on Quality of Life and Adherence in Haemodialysis Patients: A Cross-Sectional Study in Greece

There is clear evidence of a link between dialysis adequacy (as measured by urea kinetic modeling or urea reduction ratio) and such important clinical outcomes as morbidity and mortality. Evidence regarding the relationship between dialysis adequacy and quality of life (QOL) outcomes as well as adherence is less clear. The present paper is a study protocol which is planning to answer the following research question: what is the impact of dialysis adequacy on QOL and adherence in a sample of hemodialysis patients? The final sample size will be around 100 patients undergoing hemodialysis. Each subject’s QOL and adherence will be measured using the following instruments: i) the Missoula-VITAS quality of life index 25; ii) the multidimensional scale of perceived social support and iii) the simplified medication adherence questionnaire. Dialysis adequacy is expected to be related to QOL and adherence scores.

Stroke-free status and depression scores among Saudi dialysis patients

BACKGROUND

To assess the prevalence of stroke symptoms and depression among Saudi dialysis patients and related factors.

METHODS

This is a cross-sectional multicentre study of Saudi dialysis patients. Demographics, clinical and laboratory's data were collected. Freedom from stroke symptoms was assessed using the Questionnaire for Verifying Stroke-Free Status and depression using the Geriatric Depression Scale.

RESULTS

Five-hundred and forty-nine patients (77.3% response rate); 94.6% were receiving hemodialysis and 5.4% peritoneal dialysis were included in the study. Freedom from stroke was reported in 76.6% of patients, was higher in females (p = 0.07), and was not affected by the presence of diabetes mellitus coronary artery disease or peripheral vascular disease. However, it was significantly lower in hypertensive patients (p = 0.035) and was not affected by age, dialysis duration, Kt/V, albumin or hemoglobin levels. It was, however, more prevalent in the non-depressed patients compared to depressed patients (p = 0.036). Mild and major depression scores were noted in 45.2% and 6.1%, respectively; the depression score being significantly higher in HD than in PD patients (6.3 ± 3.4 vs. 5.0 ± 3.2 p = 0.049) but was not related to sex, employment, vascular access type, age, dialysis duration, Kt/V or serum albumin or hemoglobin levels.

CONCLUSION

A quarter of the patients were not stroke symptom-free and these were more likely the depressed patients, in females, but significantly less in hypertensive patients. Almost half of the patients were depressed with 6.1% having major depression. The depression score was significantly higher in HD than in PD patients.

Medication adherence in Greek hemodialysis patients: the contribution of depression and health cognitions

BACKGROUND

Several studies have shown that non-adherence is a common and increasing problem among individuals with chronic illnesses, including hemodialysis patients.

PURPOSE

The present study aimed to investigate the influence of depression and health cognitions on medication adherence among patients undergoing hemodialysis.

METHOD

A sample of 168 participants was recruited from six general hospitals in the broader area of Athens, consisting of patients undergoing in-center hemodialysis. Measurements were conducted with the following instruments: the Medication Adherence Rating Scale, the Center for Epidemiologic Studies Depression Scale (CES-D), and the Multidimensional Health Locus of Control (MHLC) scale.

RESULTS

The results indicated that medication adherence was associated positively with the dimensions of internal and doctor-attributed health locus of control, measured by the MHLC. It was also related negatively to depression, measured by the CES-D.

CONCLUSIONS

The present study demonstrates the importance of depression in understanding the medication adherence of hemodialysis patients, as well as the contribution of heath cognitions.

Factors affecting the physician-patient relationship of older veterans with inadequate health literacy: an observational study

BACKGROUND

In Taiwan, older veterans typically match the characteristics of a high prevalence of inadequate health literacy, which is a major barrier to effective communication in delivering proper health care. A good physician-patient relationship increases patients' trust and willingness to communicate, so an awareness of the factors that influence this relationship could improve it over time and enhance patients' health.

AIM

To explore factors related to the physician-patient relationship among older veterans with inadequate health literacy in Taiwan.

DESIGN AND SETTING

Observational study in veterans' homes.

METHOD

Data were collected using self-report questionnaires in face-to-face interviews. Patients with a Test of Functional Health Literacy in Adults score <60 (defined as inadequate health literacy) were recruited. Demographic characteristics, the Geriatric Depression Scale-Short Form, Multidimensional Health Locus of Control, and Perceived Involvement in Care Scales were used to identify related factors. Multiple regression and bootstrapping were used for data analyses.

RESULTS

A total of 256 older individuals were defined as having inadequate health literacy. Patients' perceived involvement in health care partially mediated the relationship between Health Locus of Control and the physician-patient relationship. Perceived Involvement in Care, depression score, and Health Locus of Control were predictors of the physician-patient relationship.

CONCLUSION

Older patients with inadequate health literacy had difficulty becoming actively involved in health care. The GP is in an ideal position to become a key person in helping such patients become involved in health care, and appropriately treating their depression may improve the physician-patient relationship.

Illness perceptions predict exercise capacity and psychological well-being after pulmonary rehabilitation in COPD patients

OBJECTIVE

Patients' beliefs about their disease have been associated with emotional adjustment and outcomes in several severe illnesses. The aim of the present study was to investigate whether illness perceptions before pulmonary rehabilitation influence exercise capacity and quality of life after rehabilitation in patients suffering from chronic obstructive pulmonary disease (COPD).

METHODS

Ninety-six patients with COPD (GOLD III/IV) were approached on admission to rehabilitation and reassessed before discharge. Assessment included medical measures of FEV% predicted, and exercise capacity (6 min walk test). Additionally, depressive symptoms (Hospital Anxiety and Depression scale), anxiety (COPD specific anxiety questionnaire) and quality of life (Short Form 36 health survey (SF-36)) were assessed. Illness beliefs were measured by the Revised Illness Perception Questionnaire (IPQ-R).

RESULTS

Exercise capacity and psychological well-being (SF-36) of patients improved after rehabilitation programme, while physical functioning (SF-36) did not change. Additionally, patients showed significantly lower levels of depressive symptoms, COPD specific anxiety and negative perceptions of their illness after pulmonary rehabilitation compared to baseline. In the hierarchical multiple regression analyses, after controlling for socio-demographic data, psychological variables, illness severity and baseline scores of the corresponding variables, it was shown that illness perceptions before rehabilitation predicted exercise capacity and psychological well-being, both assessed at the end of treatment.

CONCLUSION

COPD patients' perceptions about their illness before rehabilitation influence exercise capacity and quality of life (psychological well-being) after treatment. Therefore it might be relevant to identify and change maladaptive illness perceptions in order to improve medical and psychological outcome in COPD.

Relationship between mental health and spiritual wellbeing among hemodialysis patients: a correlation study

CONTEXT AND OBJECTIVE

The stress of living with a terminal disease has a negative impact on the mental health of hemodialysis (HD) patients. Spirituality is a potential coping mechanism for stressful experiences. Studies on the relationship between spirituality and mental health among HD patients are scarce. The purpose of this study was to evaluate the relationship between mental health and spiritual well-being among HD patients.

DESIGN AND SETTING

Cross-sectional observational study on hemodialysis patients at a single center in Brazil, between January and December 2011.

METHODS

Mental health was assessed using the General Health Questionnaire and spiritual wellbeing was assessed using the Spiritual Wellbeing Scale; 150 HD patients participated in the study.

RESULTS

A significant correlation was found between mental health and spiritual wellbeing (P = 0.001). Spiritual wellbeing was the strongest predictor of mental health, psychological distress, sleep disturbance and psychosomatic complaints.

CONCLUSION

Poor mental health was associated with lower spiritual wellbeing. This has important implications for delivery of palliative care to HD patients.

Measuring Pain Self-Efficacy and Health Related Quality of Life Among Hemodialysis Patients in Greece: A Cross-Sectional Study

Patients suffering from end-stage kidney disease often complain about pain. It is also known that the presence of chronic pain greatly impacts upon patients’ quality of life (QOL) and can play a crucial role in the co-morbidity of mental health symptoms such as depression and anxiety. The main aim of this study protocol is the investigation of pain self-efficacy, QOL as well as their relation in patients undergoing hemodialysis treatment. The final sample size will be around 70-80 patients. Each subject’s QOL and pain self-efficacy will be measured using the following instruments: i) the Missoula- ITAS Quality of Life Index-15 and ii) the Pain Self-Efficacy Questionnaire. QOL is expected to be related to pain self-efficacy scores. This probable association will be indicated performing regression as well as correlation analysis after controlling for gender, age, education and marital status.

Spiritual coping, religiosity and quality of life: a study on Muslim patients undergoing haemodialysis

AIM

The number of haemodialysis patients globally is increasing and spiritual resources may help overcome adjustment problems among such patients. This study examined the relationships between spiritual/religious, demographic and clinical variables and quality of life among Iranian Muslims undergoing haemodialysis.

METHODS

Using a cross-sectional design, 362 haemodialysis patients were surveyed from three general hospitals located in Tehran, Iran. Spiritual coping strategies, Duke University Religion Index, EQ-5D 3L and a demographic questionnaire were administered. Hierarchical regression was used to identify predictors of quality of life and health status.

RESULTS

The distribution of reported problems across dimensions of quality of life was: mobility (59.4%), usual activities (30.4%), self-care (21.3%), pain/discomfort (47.8%) and anxiety/depression (29.3%). Univariate analysis showed that factors such as age, sex, marital status, location, number of children, body mass index, serum albumin, having diabetes mellitus or other comorbidity, as well as spiritual/religious factors that were related to quality of life, health status or both. Regression models revealed that demographics, clinical variables and especially spiritual/religious factors explained about 40% of variance of quality of life and nearly 25% of the variance in health status.

CONCLUSION

Spiritual resources may contribute to better quality of life and health status among haemodialysis patients. Further longitudinal studies are needed to determine whether these associations are causal and the direction of effect.

Self-Reported Functional Status

Functional status is an understudied, yet important, modifiable risk factor in a number of chronic illnesses. This topic has not yet been studied extensively for chronic kidney disease (CKD). This study investigates the relationship of functional status to mental health and health perceptions among patients undergoing hemodialysis and peritoneal dialysis. A sample of 144 patients was recruited, consisting of 84 patients undergoing hemodialysis (HD) and 60 patients in peritoneal dialysis (PD). Measurements were conducted with the following instruments: the World Health Organization Quality of Life instrument (WHOQOL-BREF), the General Health Questionnaire (GHQ-28), the State-Trait Anxiety Inventory (STAI 1/STAI 2), the Center for Epidemiologic Studies Depression Scale (CES-D), and the Multidimensional Health Locus of Control (MHLC). Functional status was associated negatively with all subscales of the GHQ-28 (somatic symptoms, anxiety/insomnia, social dysfunction, severe depression) and the GHQ-28 total score. It was also related negatively to depression, as measured by CES-D scale, as well as to state and trait anxiety, and positively to internal health locus of control. The present study demonstrates the importance of functional status in understanding the health perceptions of patients with CKD and the contribution of functional status to mental health.

A literature review to investigate the link between psychosocial characteristics and treatment adherence in cancer patients

Adherence to medication has been recognized as a key issue in health outcomes and efforts to improve patients' adherence are being made by the pharmaceutical industry, experts, and government bodies alike. This paper presents a review of these issues according to previous descriptive findings. Relevant studies written in English, published in 1976 or later, were identified through Medline, Embase and PsycInfo databases and reviewed. Review articles and clinical trials were excluded; all observational studies and surveys were considered. Articles were reviewed for any discussion of patients' characteristics and psychosocial characteristics affecting adherence to cancer treatment. The search strategy included a combination of key words adherence and cancer in titles. The major findings are summarized and presented under two main headings: i) patients' characteristics; and ii) psychosocial characteristics. In general, factors associated with increased likelihood of adherence to cancer treatment included younger age, higher education, higher income and Caucasian ethnicity. With regards to the psychosocial factors, lower levels of depression and anxiety, optimism as well as social support seemed to have a positive effect on treatment adherence. Studies of patterns of care in cancer treatment can help identify challenges in health care provided to particular subgroups of cancer patients and can aid researchers in designing studies that account for such factors in clinical and outcomes' research.

Noncompliance with medical regimen in haemodialysis treatment: a case study

Patients undergoing haemodialysis treatment have a high burden of disease (particularly cardiovascular comorbidities) affecting their quality of life and dramatically shortening life expectancy. Effective chronic kidney disease (CKD) control requires regular preventive medication and a response to that medication. Poor receptiveness to CKD medication can be related to individual variability in the dose needed to achieve a response, as well as to low-adherent behaviour in relation to the CKD medication regimen. Some patients, though not many, according to studies' findings, abuse the medical regimen as a result of suicidal tendencies. The present case gave us the opportunity to consider the causes and clinical findings and review the specific psychological interventions for patients with CKD.
