Predictive model of variables associated with health-related quality of life in patients with advanced chronic kidney disease receiving hemodialysis

Social support and family resilience among Chinese people receiving maintenance hemodialysis: A polynomial regression and response surface analysis explaining psychological resilience

Psychological resilience plays an important role in overcoming emotional distress among people receiving maintenance hemodialysis (MHD). This study aimed to investigate how social support and family resilience interact to influence psychological resilience among Chinese people receiving MHD. This was a prospective longitudinal study with three time points: baseline (T1), 3 months (T2), and 6 months (T3) later. A convenience sample of 252 participants (67.1% male; 57.6 ± 13.8 years of age) from Zhejiang Province, China, who completed baseline measures of social support, family resilience, and psychological resilience, were further assessed for psychological resilience at T2 and T3. Polynomial regression (PR) and response surface analysis (RSA) were used to analyze the data. At all time points, and in the case of agreement between social support and family resilience, the combined effect of both variables manifested as a positive linear association with psychological resilience. Instead, at baseline, and in case of disagreement, the same combined effect manifested as a negative linear relationship related to psychological resilience. The findings highlighted the importance of considering the conjoint influence of social support and family resilience when developing interventions to improve the psychological resilience of people receiving MHD.

Central sensitization: its prevalence and impact on quality of life among hemodialyzed patients

BACKGROUND/AIM

Data on the role of central sensitization in hemodialyzed patients are scarce. The aim was to identify the impact of central sensitization on quality of life and elucidate the risk factors for the development of central sensitization in patients receiving hemodialysis.

METHODS

Central sensitization, quality of life, psychological well-being, and sleep were assessed by the Central Sensitization Inventory (CSI), abbreviated version of the World Health Organization Quality of Life Instrument (WHOQOL-BREF), Hospital Anxiety and Depression Scale (HADS), and Jenkins Sleep Evaluation Scale (JSS), respectively. The effect of central sensitization on quality of life and the predictors of the development of central sensitization were assessed by regression analyses.

RESULTS

The frequency of central sensitization was 48% in the study population (n = 100). Patients with central sensitization had significantly higher pain intensity, worse sleep quality, and more impaired psychological status (p < 0.05 for all). The CSI score negatively affected all quality of life domains on its own (p < 0.001 for all, adjusted R2 ranged from 0.17 to 0.47). Dialysis vintage (OR, 0.8; 95% CI, 0.7 to 1.0), pain (OR, 1.5; 95% CI, 1.1 to 2.0), JSS (OR, 1.3; 95% CI, 1.1 to 1.5), and HADS-total (OR, 1.1; 95% CI, 1.0 to 1.2) were determined as the independent risk factors for central sensitization (p < 0.05 for all).

CONCLUSION

This study confirms that given the high frequency of central sensitization and its significant negative impact on quality of life, the presence of central sensitization should be investigated in patients undergoing hemodialysis.

Association of anxiety, depression and resilience with overall health and functioning in axial spondyloarthritis (axSpA): a cross-sectional study

OBJECTIVES

To evaluate the association between anxiety, depression and resilience with overall health and functioning in axial spondyloarthritis (axSpA).

DESIGN

Cross-sectional evaluation of baseline data from a prospective cohort study, with recruitment from January 2018 to March 2021.

SETTING

Outpatient clinic in a tertiary hospital in Singapore.

PARTICIPANTS

Patients aged 21 years and above who were diagnosed with axSpA.

OUTCOME MEASURES

The Hospital Anxiety and Depression Scale (HADS) was used for assessing anxiety and depression, 10-item Connor Davidson Resilience Scale (CD-RISC-10) for resilience, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) for disease activity, Bath Ankylosing Spondylitis Functional Index (BASFI) for functional limitation and Assessment of SpondyloArthritis International Society Health Index (ASAS HI) for overall health and functioning. Univariable and multivariable linear regression analyses were performed to assess the association between anxiety, depression and resilience with health and functioning.

RESULTS

We included 296 patients in this study. The median (IQR) score for HADS-Anxiety was 5.0 (2.0-8.0), with 13.5% and 13.9% having borderline abnormal and abnormal anxiety, respectively. The median (IQR) score for HADS-Depression was 3.0 (1.0-7.0), with 12.8% and 8.4% having borderline abnormal and abnormal depression, respectively. The median (IQR) CD-RISC-10 score was 29.0 (23.0-32.0) while the median (IQR) ASAS HI score was 4.0 (2.0-7.0). Apart from BASDAI, BASFI and disease duration, anxiety and depression were associated with overall health and functioning (β: 0.12, 95% CI 0.03, 0.20; β: 0.20, 95% CI 0.09, 0.31) in the multivariable linear regression. Level of resilience was not associated with health and functioning.

CONCLUSION

Anxiety and depression, but not resilience, were associated with poorer health and functioning. Clinicians could consider routinely screening for anxiety and depression in their patients, especially in patients with more severe symptoms.

Factors Related to Quality of Life of Hemodialysis Patients during the COVID-19 Pandemic

Taiwan had the second highest number globally of end-stage renal disease patients undergoing treatment in 2018. A meta-analysis of Chen et al. (2021) showed the incidence and mortality rates of COVID-19 were 7.7% and 22.4%, respectively. Few studies have explored the effects of patients' self-participation and perceptions of hemodialysis on their quality of life. This study aimed to explore the factors related to hemodialysis patients' quality of life during the COVID-19 pandemic. This study was a descriptive correlational study. Patients were recruited (n = 298) from the hemodialysis unit of a medical center in northern Taiwan. Variables included patients' sociodemographic, psychological, spiritual, and clinical characteristics (i.e., perceived health level, comorbidities, hemodialysis duration, weekly frequency, transportation, and accompaniment during hemodialysis), perceptions of hemodialysis, self-participation in hemodialysis, and health-related quality of life (KDQOL-36 scale). Data were analyzed using descriptive and bivariate and multivariate linear regression. Multivariate linear regression, after adjusting for covariates, showed that anxiety, self-perceived health status, two vs. four comorbidities, and self-participation in hemodialysis were significantly associated with quality of life. The overall model was significant and accounted for 52.2% (R² = 0.522) of the variance in quality of life during hemodialysis (adjusted R² = 0.480). In conclusion, the quality of life of hemodialysis patients with mild, moderate, or severe anxiety was poorer, whereas that of patients with fewer comorbidities, higher self-perceived health status, and higher self-participation in hemodialysis was better.

Conclusión: El tratamiento con hemodiálisis cambia el pronóstico de la enfermedad renal crónica, disminuyendo la morbilidad y la mortalidad. La persona durante el tratamiento debe adaptarse y enfrentar cambios físicos, fisiológicos, emocionales, sociales y familiares

The impact of vascular access satisfaction on health-related quality of life in patients receiving maintenance hemodialysis: A 2-year follow-up study

Background:

Health-related quality of life (HRQoL) has been demonstrated to predict mortality in patients receiving maintenance hemodialysis (MHD). Vascular access (VA) is critical for MHD patients. The aim of this study was to investigate the change in HRQoL among MHD patients with a 2-year follow-up and to explore the impact of VA satisfaction on HRQoL in this population.

Methods:

229 MHD patients in two dialysis centers were included in this observational prospective study. VA satisfaction was assessed using the Vascular Access Questionnaire (VAQ). The 36 Item Short-Form Health Survey (SF-36) questionnaire was employed to evaluate HRQoL scores. Multiple logistic regression analysis was used to evaluate the influencing factors of HRQoL.

Results:

A total of 229 MHD patients were enrolled in the study, and 198 individuals (86.46%) completed the 2-year follow-up. HRQoL decreased statistically significantly from baseline to the 2-year follow-up across all dimensions. Multivariable analyses showed that the overall score, social functioning score, dialysis-related complication score of VAQ influenced HRQoL in the study population. Furthermore, HRQoL total scores and scores on the physical component summary (PCS) and mental component summary (MCS) domains were significantly higher in the satisfied VA group than in the dissatisfied group at baseline. After the 2-year follow-up, patients with a higher level of VA satisfaction reported higher HRQoL than patients with lower VA satisfaction.

Conclusion:

Our data suggested that VA satisfaction was significantly associated with HRQoL in MHD patients. These findings imply that surgeons and nephrologists should incorporate patient satisfaction into VA surgical decision-making.

Factors Associated With Resilience During Long-Term Hemodialysis

BACKGROUND

Resilience has been associated with greater adherence to treatment, better outcomes, and improved quality of life (QOL) in people with chronic health conditions. This study aimed to identify sociodemographic, treatment accessibility-related, clinical, and psychological variables associated with resilience in patients with advanced chronic kidney disease (CKD) undergoing long-term hemodialysis (>6 months).

METHODS

This was a multicenter, cross-sectional, and correlational study. The instruments used were the Spanish versions of the Connor-Davidson Resilience Scale, the Perceived Stress Scale-10, and the Kidney Disease Quality of Life-36. The participants were categorized as resilient (with a score of ≥49.37 on the Connor-Davidson Resilience Scale) or nonresilient. Binary logistic regression analysis was performed to identify variables with predictive power for the group with the resilient profile.

RESULTS

Perceived stress, general QOL, and subcomponents of QOL, such as the physical component and burden of kidney disease, were identified as factors related to the resilient profile.

DISCUSSION

Identifying the factors related to resilient adjustment in patients with advanced CKD may assist health caregivers in improving adherence to treatment, treatment outcomes, and QOL.

Resilience in relation to older adults with multimorbidity: A scoping review

The purpose of this scoping review is to identify conceptual and theoretical resilience models, types of resilience measures, and outcomes regarding resilience in relation to older adults with multimorbidity. PubMed, Embase, CINAHL, and PsycINFO were searched, and we identified 14 studies to July 2021. Most models operationalize resilience as dependent on the social and environmental context of older adults. Three of the five resilience measures in the included studies are used to evaluate general resilience. They are primarily psychological or psychosocial in nature, and measuring physical resilience therefore may help to better understand individuals' ability to cope with the physical challenges associated with various chronic diseases. Quality of life and physical activity were common outcomes in studies of resilience. Findings highlight the need for studies that incorporate physiological measures or physical properties of resilience and longitudinal studies that capture the dynamic process of resilience in older adults with multimorbidity.

Well-being and health in kidney failure: A scoping review

BACKGROUND

Kidney Failure (KF) is associated with impaired physical function, reduced health-related quality of life (HRQoL), increased healthcare costs, and high rates of cardiovascular complications and mortality. Among individuals with KF, well-being and related constructs, such as positive affect, optimism, self-efficacy, and resilience, may have both mental and physical health benefits, independent of the effects of negative emotions and affective syndromes. However, there has been minimal review of these characteristics in people with KF.

METHODS

We conducted a scoping review, using a semi-systematic approach, to summarize the relationships between well-being characteristics and renal health, the potential mechanisms mediating these relationships, and the effects of interventions that promote positive constructs on adherence and health outcomes. We conducted database searches using PubMed and PsycInfo until November 2020. Articles were included if they examined (1) relationships between a well-being construct and health outcome in patients with KF, (2) potential biological or behavioral mediators, or (3) interventions that target positive psychological constructs as outcomes or mediators in KF, and (4) were written in English or Spanish.

RESULTS

Among patients with KF, well-being constructs are associated with increased health-related quality of life (HRQoL), reduced morbidity and complications, and increased survival. Potential mechanisms mediating these associations include reduced inflammation, improved autonomic and endothelial function, and improved health behavior adherence. Psychological and psychosocial interventions promoting well-being have primarily focused on improving self-efficacy to promote behavior change, with limited study of interventions to promote positive psychological constructs in this population.

CONCLUSIONS

Further research is needed to better understand the relationship between well-being constructs and health, specific to KF populations. This could inform the development of needed interventions that harness the promotion of other positive characteristics to improve well-being and health.

How to assess quality of life in persons with chronic kidney disease

PURPOSE OF REVIEW

Chronic kidney disease (CKD) significantly impacts many aspects of life, health, and wellbeing. People with CKD have individual priorities for their care which may differ from those valued by clinicians and policy makers. The patient experience is broadly captured by the concept of quality of life (QoL) which is increasing assessed in research and used to guide clinical and policy decision making. Appropriate selection and application of QoL assessment tools are essential for high-quality research and patient care. This article summarises the current approaches to QoL assessment in CKD and outlines aspirations for future improvement.

RECENT FINDINGS

Commonly used tools for assessment of QoL in CKD include the Short Form-36 and -12 and extended versions adapted for specific use in kidney patients (KD-QoL), and the EQ-5D. However, a wide range of other instruments are also reported, making comparisons between research findings challenging. Few of the tools are adequately validated for use in CKD, and relevance to patient values are unclear. Instruments suitable for use in a routine clinical setting are lacking.

SUMMARY

QoL instruments developed and validated with meaningful CKD stakeholder input are required. The Standardised Outcomes in Nephrology initiative is working to address this need.

The Impact of COVID-19 on the mental health of dialysis patients

Background

Studies have shown increased anxiety, depression, and stress levels among different populations during the coronavirus disease 2019 (COVID-19) pandemic. However, the impact of the pandemic on the mental health of dialysis patients remains unknown. The aim of this study was to investigate the mental health of dialysis patients during the COVID-19 pandemic compared to the period preceding the pandemic.

Methods

Data originate from the ongoing multicentre observational Dutch nOcturnal and hoME dialysis Study To Improve Clinical Outcomes (DOMESTICO). Patients who filled in a health-related quality of life (HRQoL) questionnaire during the pandemic and six to three months prior were included. The mean difference in Mental Component Summary (MCS) score of the Short Form 12 (SF-12) was analysed with multilevel linear regression. A McNemar test was used to compare presence of mental health-related symptoms during and prior to the COVID-19 pandemic.

Results

A total of 177 patients were included. The mean MCS score prior to COVID-19 was 48.08 ± 10.15, and 49.00 ± 10.04 during the COVID-19 pandemic. The adjusted mean MCS score was 0.93 point (95% CI − 0.57 to 2.42) higher during the COVID-19 pandemic than during the period prior to the pandemic. Furthermore, no difference in the presence of the following mental health-related symptoms was found during the COVID-19 pandemic: feeling anxious, feeling sad, worrying, feeling nervous, trouble falling asleep, and trouble staying asleep.

Conclusions

The mental health of dialysis patients appears to be unaffected by the COVID-19 pandemic. Dialysis patients may be better able to cope with the pandemic, since they have high resilience and are less impacted by social distancing measures.

Perceived Stress in Relation to Quality of Life and Resilience in Patients with Advanced Chronic Kidney Disease Undergoing Hemodialysis

Background: Patients with chronic kidney disease undergo various stages of therapeutic adaptation which involve lifestyle modifications, physical changes, and adjustment to renal replacement therapy. This process produces adaptive stress. Objective: To identify how resilience, health- related quality of life, and sociodemographic, clinical, and hemodialysis routine-related variables are related to perceived stress in patients with chronic kidney disease receiving hemodialysis for more than six months. Methods: This was a multicenter and cross-sectional study involving 144 patients from the Valencian Community (Spain). The assessment scales used for the study were the Perceived Stress Scale 10, the Kidney Disease Quality of Life 36, and the Connors–Davidson Resilience Scale. To identify variables with predictive power over Perceived Stress Scale 10 scores, multiple regression analyses were performed. Results: Employment status (p = 0.003), resilience (p < 0.001), and quality of life (p < 0.001) were shown to be significantly related to perceived stress. The regression models determined that health-related quality of life and resilience explained up to 27.1% of the variance of total PSS10 scores. Conclusions: Resilience was identified as one of the most important predictors of Perceived Stress Scale 10 scores. Thus, the development of interventions to promote resilience may have a positive impact on perceived stress in patients with chronic kidney disease.

Psychological Profiles of Chinese Patients With Hemodialysis During the Panic of Coronavirus Disease 2019

Background: Hemodialysis patients not only suffer from somatic disorders but are also at high risks of psychiatric problems. Early this year, the outbreak of coronavirus disease 2019 (COVID-19) has caused great panic and anxiety worldwide. The impact of this acute public health event on the psychological status of hemodialysis patients and its relationship with their quality of life have not been fully investigated. Methods: This study comprised two parts. The initial study enrolled maintenance hemodialysis patients treated in Ruijin Hospital for more than 3 months from March to May 2020 during the ongoing COVID-19 pandemic. Patients completed three questionnaires including the Impact of Events Scale-Revised (IES-R), General Health Questionnaire-28 (GHQ-28), and Kidney Disease Quality of Life (KDQOL) Short Form (SF). Follow-up study was performed from December 2020 to January 2021, when the pandemic of COVID-19 has been effectively contained in China. Only patients enrolled in the initial study were approached to participate in the follow-up study. Results: There were 273 maintenance dialysis patients enrolled in the initial study and 247 finished the follow-up study. For the initial study, the estimated prevalence of nonspecific psychiatric morbidity was 45.8% (125/273) by GHQ-28. By IES-R, 53/273 (19.4%) patients presented with total scores above 24 that reflected clinical concerns. We found a significant difference regarding KDQOL scores between patients with different stress response (IES-R) groups (p = 0.026). Our follow-up study showed that KDQOL and SF-36 scores were significantly improved in comparison with those in the initial study (p = 0.006 and p = 0.031, respectively). Though total scores of GHQ-28 and IES-R did not change significantly, some subscales improved with statistical significance. Furthermore, gender, education background, and duration of hemodialysis were three factors that may affect patients' mental health, quality of life, or health status while dialysis duration was the only variable that correlated with those parameters. However, these correlations were combined effects of the COVID-19 pandemic and the dialysis itself. Conclusions: We found a correlation between changes in the mental health status of dialysis patients and changes in their quality of life. These responses were also mediated by patients' psychosocial parameters. Our results urge the necessity of psychotherapeutic interventions for some patients during this event.
