Shared Decision Making for Choosing renAl Replacement Therapy in Chronic Kidney Disease Patients (SDM-ART trial): study protocol for randomized clinical trial

BACKGROUND

Patients with chronic kidney disease (CKD) should be educated about their condition so that they can initiate dialysis at the optimal time and make an informed choice between dialysis modalities. Shared decision-making (SDM) empowers patients to select their own treatment and improves patient outcomes. This study aimed to evaluate whether SDM affects the choice of renal replacement therapy among CKD patients.

METHODS

This is a multicenter, open-label, randomized, pragmatic clinical trial. A total of 1,194 participants with CKD who are considering renal replacement therapy were enrolled. The participants will be randomized into three groups in a 1:1:1 ratio: the conventional group, extensive informed decision-making group, and SDM group. Participants will be educated twice at months 0 and 2. Videos and leaflets will be provided to all patients. Patients in the conventional group will receive 5 minutes of education at each visit. The extensive informed decision-making group will receive more informed and detailed education using intensive learning materials for 10 minutes each visit. Patients in the SDM group will be educated for 10 minutes each visit according to illness perception and item-based analysis. The primary endpoint is the ratio of hemodialysis to peritoneal dialysis and kidney transplantation among the groups. Secondary outcomes include unplanned dialysis, economic efficiency, patient satisfaction, patient evaluation of the process, and patient adherence.

DISCUSSION

The SDM-ART is an ongoing clinical study to investigate the effect of SDM on the choice of renal replacement therapy in patients with CKD.

Impact of chronic kidney disease on illness perceptions, coping, self-efficacy, psychological distress and quality of life

Chronic kidney disease (CKD) negatively impacts psychological well-being and quality of life (QoL). Underpinned by the Common Sense Model (CSM), this study evaluated the potential mediating role of self-efficacy, coping styles and psychological distress on the relationship between illness perceptions and QoL in patients living with CKD. Participants were 147 people with stage 3-5 kidney disease. Measures included eGFR, illness perceptions, coping styles, psychological distress, self-efficacy and QoL. Correlational analyses were performed, followed by regression modelling. Poorer QoL was associated with greater distress, engagement in maladaptive coping, poorer illness perceptions and lower self-efficacy. Regression analysis revealed that illness perceptions predicted QoL, with psychological distress acting as a mediator. The proportion of variance explained was 63.8%. These findings suggest that psychological interventions are likely to enhance QoL in CKD, if they target the mediating psychological processes associated with illness perceptions and psychological distress.

Patients' perspectives of fluid management: A multicentre comparative study of home and incentre haemodialysis

BACKGROUND

There is increasing worldwide interest in person-centred care in haemodialysis and home haemodialysis (HHD). Intradialytic fluid management is a vital component of haemodialysis, and often a shared decision, yet patients' perspectives and experience of related decisions are largely unexplored.

OBJECTIVES

To explore the perspectives of patients receiving home or incentre haemodialysis (IHD), in relation to intradialytic fluid management.

DESIGN

A multicentre cross-sectional survey.

PARTICIPANTS

Eight hundred and thirty-nine patients receiving IHD and 99 patients receiving HHD, across six English renal units.

MEASUREMENTS

Self-reported measures of understanding, experiences and control of fluid management, and willingness to achieve target weight. An objective test of patients' ability to relate common signs and symptoms to fluid overload or excessive ultrafiltration.

RESULTS

Patients receiving HHD had greater knowledge than those receiving IHD (66.1% vs. 42.3%, p < 0.001) about causes of common signs and symptoms which remained when controlling for age, education and years since beginning haemodialysis. Patients receiving HHD felt more in control of and had greater self-reported adherence to fluid management (p < 0.01), yet knowledge gaps existed in both cohorts.

CONCLUSIONS

Greater patient knowledge and its practice in HHD may contribute to improved fluid balance and outcomes. Whilst patient selection may contribute towards these differences, the training patients receive when opting for HHD and subsequent experience are likely to be key contributing factors. Integrating aspects of education on fluid management from HHD training programmes should be considered in IHD, and further targeted, robust education remains an unmet need.

Factors affecting uptake of home hemodialysis among self-care dialysis unit patients

INTRODUCTION

Superior outcomes have been reported among hemodialysis (HD) patients who take active control over their dialysis treatment either at self-care satellite dialysis units or home compared to the regular in-center hemodialysis patient. Although the differences between the home hemodialysis (HHD) and self-care in-center HD (SCHD) are not well described, the growing literature on the superior outcomes of HHD suggests that HHD is the better option.

METHODS

We performed a cross-sectional study in a stand-alone self-care unit to examine the differences in patients that are keen to consider HHD and those who are not.

FINDINGS

A cross-sectional sample of 44 patients completed a structured interview and the distress thermometer score used to assess psychological stress. Only 68% of patients reported to have heard about the benefits of HHD despite the long-established history and availability of the modality in the unit. One of the more critical findings in our study was that the cohort of patients who were keen to consider HHD believed that self-care and HHD would improve their quality of life (P < 0.05). Specifically, the perceived benefits stated by those willing to consider HHD were the lack of need to travel, association with better outcomes and the possibility of having the treatment in the comfort of home (P < 0.05).

DISCUSSION

We surmise that the answers expressed in this survey likely reflect a difference in perceptions of self-care and beliefs about HHD; hence, the importance of introducing HHD education earlier in the course of their chronic kidney disease journey.

The prevalence of mild-to-moderate distress in patients with end-stage renal disease: results from a patient survey using the emotion thermometers in four hospital Trusts in the West Midlands, UK

OBJECTIVES

To assess the prevalence of mild-to-moderate distress in patients with end-stage renal disease (ESRD) and determine the association between distress and patient characteristics.

DESIGN

Cross-sectional survey using emotion thermometer and distress thermometer problem list.

SETTING

Renal units in four hospital Trusts in the West Midlands, UK.

PARTICIPANTS

Adult patients with stage 5 chronic kidney disease who were: (1) On prerenal replacement therapy. (2) On dialysis for less than 2 years. (3) On dialysis for 2 years or more (4) With a functioning transplant.

OUTCOMES

The prevalence of mild-to-moderate distress, and the incidence of distress thermometer problems and patient support needs.

RESULTS

In total, 1040/3730 surveys were returned (27.9%). A third of survey respondents met the criteria for mild-to-moderate distress (n=346; 33.3%). Prevalence was highest in patients on dialysis for 2 years or more (n=109/300; 36.3%) and lowest in transplant patients (n=118/404; 29.2%). Prevalence was significantly higher in younger versus older patients (χ²=14.33; p=0.0008), in women versus men (χ²=6.63; p=0.01) and in black and minority ethnic patients versus patients of white ethnicity (χ²=10.36; p=0.013). Over 40% of patients (n=141) reported needing support. More than 95% of patients reported physical problems and 91.9% reported at least one emotional problem.

CONCLUSIONS

Mild-to-moderate distress is common in patients with ESRD, and there may be substantial unmet support needs. Regular screening could help identify patients whose distress may otherwise remain undetected. Further research into differences in distress prevalence over time and at specific transitional points across the renal disease pathway is needed, as is work to determine how best to support patients requiring help.

Screening for psychological distress using the Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS): Initial validation of structural validity in dialysis patients

OBJECTIVE

To validate the factor structure of the Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS)- which is a composite measure of depression and anxiety using the Patient Health Questionnaire-9 and Generalised Anxiety Disorder Scale (GAD-7), in a sample of haemodialysis patients.

METHOD

Screening data (n=182) used to select entry into a feasibility study of an online cognitive-behavioural therapy intervention for distress in dialysis patients were analysed here. Structural validity of the PHQ-ADS was evaluated using confirmatory factor analysis (CFA), assessing alternative models including a bi-factor model. In the bi-factor model all items from the PHQ-9 and GAD-7 (16-items in total) were loaded onto a general distress factor. Respective items of the PHQ-9 and GAD-7 were specified as subgroup factors. Omega-hierarchical was calculated to indicate the level of saturation of a multidimensional scale by a general factor. Construct validity was determined against the Brief Illness Perception Questionnaire.

RESULTS

A bi-factor PHQ-ADS model had good fit to the data (chi-square=96.1, p=0.26, CFI=0.99; TLI=0.99; RMSEA=0.02). The general distress factor accounted for approximately 84% of the explained variance (omega-h=0.90). Distress scores were significantly higher in females compare with males. There was a significant association between distress and negative illness perceptions (r=0.58, p<0.01).

CONCLUSIONS

The PHQ-ADS appears to have good structural validity in haemodialysis patients and is sufficiently unidimensional to warrant the use of a total distress score. A full psychometric analysis of the PHQ-ADS in a larger sample of dialysis patients is warranted.

Spiritual Well-Being, Depression, and Stress Among Hemodialysis Patients in Jordan

Purpose: The spiritual dimension of a patient’s life is an important factor that may mediate detrimental impacts on mental health. The lack of research investigating spiritual well-being, religiosity, and mental health among Jordanian hemodialysis patients encouraged this research. This study explored levels of spiritual well-being and its associations with depression, anxiety, and stress. Design: A quantitative, cross-sectional correlational study. Method: A sample of 218 Jordanian Muslim hemodialysis patients completed a structured, self-administered questionnaire. The data were analyzed using descriptive statistics and linear multivariate regression models. Findings: The hemodialysis patients had, on average, relatively low levels of spiritual well-being, moderate depression, severe anxiety, and mild to moderate stress. The results of the regression models indicated that aspects of spiritual well-being were negatively associated with depression, anxiety, and stress, but only existential well-being consistently retained significant associations after controlling for religious well-being, religiosity, and sociodemographic variables. Conclusions: Greater spiritual and existential well-being of Jordanian hemodialysis patients were significantly associated with less depression, anxiety, and stress. It appears that these patients use religious and spiritual beliefs and practices as coping mechanisms to overcome their depression, anxiety, and stress. The implications for holistic clinical practice are explored.

Exploring the nature of illness perceptions in people with end-stage kidney disease

BACKGROUND

Diagnosis and treatment for End-Stage Kidney Disease (ESKD) results in vast lifestyle changes. Despite the high prevalence of depression in people with ESKD, the psychosocial impacts of ESKD are still often overlooked. Illness perceptions enable people to make sense of their illness and are closely associated with depression. Due to the high levels of depression within ESKD, this study sought to understand the nature of illness perceptions in people with ESKD.

METHODOLOGY

In this qualitative study, eleven participants were identified through hospital and online patient support groups. Semi-structured interviews were audio-taped, transcribed and analysed using grounded theory techniques.

RESULTS

Three themes emerged from the data: Renal Conflicts, Forced Adjustment and Coping. The main dimensions of illness perception discussed by participants were Consequences, Control, Timeline and Identity.

CONCLUSION

The results of this study have practical implications for informing practitioners about the psychosocial effects of ESKD diagnosis and treatment.

Changes of perceived control after kidney transplantation: a prospective study

AIMS

The aim of this study was to determine if kidney transplantation is associated with increases of perceived control and how changes of perceived control affect the course of psychological distress until 1 year after transplantation.

BACKGROUND

Low levels of perceived control are associated with reduced well-being among dialysis patients.

DESIGN

Prospective longitudinal cohort study.

METHODS

Perceived control (Mastery Scale) and psychological distress (GHQ-12) were prospectively assessed before (T0; n = 470) and three (T1; n = 197), six (T2; n = 210) and twelve (T3; n = 183) months after transplantation. Differences between T1 and T0 perceived control were used to stratify the sample into three groups (control gain, stable control and control loss). Socio-demographic and clinical variables, including complications, were examined as potential correlates and the course of psychological was distress compared across groups. Data were collected between July 2008 - July 2013.

RESULTS

Perceived control showed a small increase overall, with 35·1%, 50·0% and 14·9% reporting gain, stable level and loss respectively. Patients with secondary schooling were overrepresented in the control loss group. The course of psychological distress varied across perceived control change groups, with patients in the control gain group experiencing a significant reduction in psychological distress.

CONCLUSION

A considerable number of patients report increased levels of perceived control after transplantation that are associated with a subsequent decrease in psychological distress. Results emphasize the importance of perceived control and could inform interventions to facilitate well-being after kidney transplantation.

Illness Beliefs in End Stage Renal Disease and Associations with Self-Care Modality Choice

Background

Interest in self-care haemodialysis (HD) has increased because it improves patients’clinical and quality-of-life outcomes. Patients who undertake self-management for haemodialysis may hold illness beliefs differently to those choosing institutional care at the time of making the modality choice or moulded by their illness and dialysis treatment experience. Illness perceptions amongst predialysis patients and in those undertaking fully-assisted and self-care haemodialysis are being investigated in a combined cross-sectional and longitudinal study.

Study Design

The study data are derived from the BASIC-HHD study, a multicentre observational study on factors influencing home haemodialysis uptake. 535 patients were enrolled into three groups: Predialysis CKD-5 group, prevalent ‘in-centre’ HD and self-care HD groups (93% at home). We explore illness perceptions in the cross-sectional analyses of the three study groups, using the revised Illness Perception Questionnaire (IPQ-R). Predialysis patients’ illness beliefs were reassessed prospectively, typically between 4 and 12 months after dialysis commencement.

Results

Illness belief subscales are significantly different between in-centre and self-care HD groups. In a step-wise hierarchical regression analysis, after adjustment for age, education, marital status, diabetes, dialysis vintage, depression, anxiety scores, and IPQ-R subscales, personal control (p = 0.01) and illness coherence (p = 0.04) are significantly higher in the self-care HD group. In the predialysis group, no significant associations were found between illness representations and modality choices. In prospectively observed predialysis group, scores for personal control, treatment control, timeline cyclical and emotional representations reduced significantly after commencing dialysis and increased significantly for illness coherence.

Conclusions

Illness beliefs differ between hospital and self-care haemodialysis patients. Patient’s affect and neurocognitive ability may have an important role in determining illness beliefs. The impact of modality upon illness representations may also be significant and remains to be explored.

Lived experiences and illness representation of Taiwanese patients with late-stage chronic kidney disease

This qualitative study was designed to identify patients' experiences and perceptions related to living with late-stage chronic kidney disease. Interviews were held for 15 patients with late-stage chronic kidney disease from two medical centers in Taiwan. Five themes were identified using content analysis: experiencing moderate to severe symptoms and signs; tracing back to causes; realizing the long-term, irreversible nature of the disease; facing the consequence of unavoidable deterioration; and coping with the disease. The findings present the special lived experiences of Taiwanese chronic kidney disease patients and highlight the need for healthcare providers to assess patients' illness representation before offering interventions for patients coping with chronic kidney disease.

Exploring the relationships between health status, illness perceptions, coping strategies and psychological morbidity in a chronic kidney disease cohort

BACKGROUND

Using the common sense model of illness adjustment, this study aimed to explore the impact of chronic kidney disease (CKD) on individual illness perceptions, coping styles and psychological well-being.

METHODS

Eighty individuals (50 men and 30 women) with an average age of 62.66 years (standard deviation, 11.98) were included in the study. All participants were under the care of the Renal Unit of a metropolitan tertiary referral hospital. Twenty-nine patients (36%) had CKD stage 3b-4, and 51 (64%) had CKD stage 5 (or end stage kidney disease [ESKD]). Disease severity was evaluated using the health perceptions questionnaire, coping styles assessed with the Carver brief COPE scale, illness perceptions explored with the brief illness perceptions questionnaire and anxiety and depression measured using the hospital anxiety and depression scale.

RESULTS

The hospital anxiety and depression scale assessment revealed 13 patients (16.3%) with moderate or severe anxiety and 6 (7.5%) with moderate depression. Consistent with the common sense model, disease activity had a significant direct influence on illness perceptions, while, in turn, illness perceptions had a significant direct influence on depression and anxiety. Adaptive and maladaptive coping were found to mediate the relationship between illness perceptions, and anxiety and depression.

CONCLUSIONS

The results provide evidence that it is the perception of an illness rather than the actual symptoms themselves that best account for adaption to CKD. These findings suggest that intervention strategies aimed at increasing psychological well-being need to focus on changing illness perceptions rather than improving symptoms of CKD or coping mechanisms.

A 1-year follow-up study exploring the associations between perception of illness and health-related quality of life in persons with chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disease with an increasing prevalence worldwide. Its potential consequences, including reduced function and reduced social participation, are likely to be associated with decreased health-related quality of life (HRQoL). However, illness perceptions and self-efficacy beliefs may also play a part in determining HRQoL in persons with COPD. The aim of this study was to explore the relationships between illness perceptions, self-efficacy, and HRQoL in a sample of persons with COPD in a longitudinal perspective. The context of the study was a patient education course from which the participants were recruited. Data concerning sociodemographic variables, social support, physical activity, illness perceptions, general self-efficacy, and HRQoL were collected before the course started and 1 year after completion. Linear regression was used in the analyses. The results showed that less consequences and less symptoms (identity) were associated with higher physical HRQoL (PCS) at baseline and at 1-year follow-up. Less emotional response was similarly associated with higher mental HRQoL (MCS) at both time points. Lower self-efficacy showed a borderline significant association with higher PCS at baseline, but was unrelated to MCS at both time points. Self-efficacy showed no influence on the associations between illness perceptions and HRQoL. In conclusion, the study showed that specific illness perceptions had a stable ability to predict HRQoL in persons with COPD, whereas self-efficacy did not. The associations between illness perceptions and HRQoL were not mediated by self-efficacy.

Illness perceptions in patients with somatoform disorders: Examining the role of comorbidity

We examined the role of comorbidity in models that use the illness perceptions of patients with somatoform disorders to explain their outcomes. A total of 138 primary care patients with somatoform disorders completed the Patient Health Questionnaire and Brief Illness Perception Questionnaire and rated their general health status. Medical comorbidity was rated by the general practitioner. Patients’ illness perceptions were consistently related to their outcomes independent of medical and psychological comorbidity in our models. At the same time, inclusion of comorbidity enhanced our models, revealing differences in the relevance of the specific comorbidity depending on the outcome measure.

A multicentre postal survey investigating the contribution of illness perceptions, coping and optimism to quality of life and mood in adults with muscle disease

OBJECTIVE

To replicate the finding that illness perceptions influence quality of life in adults with muscle disease and to explore the additional influence of coping and optimism on quality of life and mood.

DESIGN

A postal survey including questionnaires recording quality of life, mood, illness perceptions, optimism, coping and functional impairment.

SETTING

National Health Service muscle clinics in the United Kingdom.

PARTICIPANTS

A convenience sample of adults with muscle disease.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Individualised Neuromuscular Quality of Life Questionnaire, Hospital Anxiety and Depression Scale.

RESULTS

A total of 226 completed questionnaires were returned. Although functional impairment explained most of the variance in three out of eight quality of life domains, psychological factors explained greater amounts of variance (between 19% and 52% of variance) in all other quality of life domains and in both mood domains (between 45% and 48% of variance). Overall, illness perceptions explained much of the variance in quality of life and mood score (between 5% and 37% of variance), while coping (up to 8% of variance) and optimism (up to 15% of variance) explained smaller amounts of variance.

CONCLUSION

The results confirm that illness perceptions are associated with quality of life in muscle disease and suggest that they also influence mood. The addition of optimism and coping variables into the analysis yielded small increases in the proportions of variance in quality of life and mood which were explained. These results have implications for the composition of future psychological interventions.

Trajectories of illness perceptions in persons with chronic illness: An explorative longitudinal study

Accurate illness perceptions are essential to the self-management of chronic illness. This study explored trajectories of illness perceptions in persons with morbid obesity ( n = 53) and persons with chronic obstructive pulmonary disease ( n = 52) following a patient education course. Participants completed the Brief Illness Perception Questionnaire five times over a 1-year period. Repeated measures analysis of variance was employed. Over time, obese participants perceived shorter illness duration, fewer consequences, less emotional stress, and more personal control. Chronic obstructive pulmonary disease participants had initial increases in personal control and understanding, but these changes were not maintained throughout the follow-up period.

Psychosocial functioning in adults with beta-thalassaemia major: Evidence for resilience

Our aims were to compare the psychosocial functioning of a sample of adults with beta-thalassaemia major to that of a control sample and to examine the protective role of quality of relationship with parents during adolescence and perceived quality of care. A total of 85 Italian beta-thalassaemia major participants and 73 controls completed an ad hoc questionnaire. Compared with controls, beta-thalassaemia major participants did not differ on relationships with significant others and coping strategies. Beta-thalassaemia major participants reported higher scores on job satisfaction, self-esteem and self-description. The relationship with parents during adolescence and the perceived quality of care significantly predicted higher well-being and psychosocial functioning.

Comparative symptomatology of burnout and depression

The link between burnout and depression remains unclear. In this study, we compared depressive symptoms in 46 burned-out workers, 46 outpatients experiencing a major depressive episode, and 453 burnout-free workers to test the distinctiveness of burnout as a clinical entity. Participants with burnout and major depressive episode reported similar, severe levels of overall depressive symptoms. The between-syndrome overlap was further verified for eight of the nine major depressive episode diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.). Our findings do not support the view hypothesizing that burnout and depression are separate entities and question the nosological added value of the burnout construct.

The importance of illness perceptions, quality of life and psychological status in patients with ulcerative colitis and Crohn’s disease

The present study investigates illness perceptions of inflammatory bowel disease patients in an outpatient population, examining whether these illness perceptions are related to disease severity, quality of life and psychological adjustment. A cohort of 102 inflammatory bowel disease outpatients was prospectively enrolled on the study. The participants completed a questionnaire assessing illness perceptions, anxiety, depression and disease-specific symptoms. The study has identified specific illness perceptions of inflammatory bowel disease sufferers that are strongly associated with patients’ quality of life. By raising and addressing these issues, clinicians may be able to allay these significant and often unexpressed concerns, and improve quality of life for patients with inflammatory bowel disease.

The association between discrepancy in illness representations on distress in stroke patients and carers

BACKGROUND

To investigate the association between the illness representations of recently diagnosed stroke patients and their carers and distress in the months after stroke.

METHOD

Forty-two stroke survivors and their carers were assessed at 3 months and 32 couples returned data at 6 months after stroke. Patients and carers completed the Illness Perceptions Questionnaire-Revised, Barthel Index, Significant Others Scale and General Health Questionnaire. Analyses were conducted using the Actor-Partner Interdependence Model.

RESULTS

Carers were more pessimistic than patients about the symptoms, timeline and consequences of the stroke. Patient distress was associated with both patient and carer illness representations at Time 1, and their own illness representations and discrepancy in the illness representations of patients and carers at Time 2. Carer distress was associated with their own illness representations at Time 1, but not the patient's illness representations. Discrepant illness representations were associated with higher carer distress at Time 1 but not Time 2.

CONCLUSION

Illness representations of stroke patients and carers have implications for adjustment for both partners. It is important to understand couples' views of stroke, as discrepancy was as strongly associated with patient and carer distress as was physical disability.

Illness beliefs and treatment beliefs as predictors of short and middle term outcome in depression

The article investigates whether illness beliefs and beliefs about rehabilitation are predictors of short and middle term outcome in depression even when adjustments are made for variables, which are known to be predictors of the course of depression. Within the context of a non-controlled prospective study design, data were analyzed using forced entry hierarchical multiple regression analyses. The sample comprised N = 98 patients. Adjusting for a range of sociodemographic and medical predictors, illness beliefs and beliefs about rehabilitation predict outcome in depression. Illness beliefs and beliefs about rehabilitation are relevant starting points for designing patient-oriented interventions.
