Transplant-related Symptom Clusters in Renal Transplant Recipients

Development and Psychometric Evaluation of the Social Participation Questionnaire: A Methodological and Cross-Sectional Study

PURPOSE

Social participation is vital for the health maintenance of general populations as well as the functional recovery and social ties of clinical patients. To develop a Social Participation Questionnaire (SPQ) to evaluate participation in social activities in an individual's life and to test the reliability and validity of the SPQ.

DESIGN

Cross-sectional study.

SETTING

Community and clinic in China.

SUBJECTS

A total of 1419 healthy adults and 486 breast cancer patients.

MEASURES

The initial items were developed from a theoretical framework, a literature review, and Delphi expert consultation. Item analysis, exploratory (EFA) and confirmatory factor analysis (CFA), criterion validity, construct reliability, and internal consistency reliability were performed to examine the psychometric properties of the SPQ.

RESULTS

The final SPQ was comprised of 11 different types of social activities, falling under the 3 dimensions of activities of daily life, sports and entertainment activities, and social service activities. EFA explained 50.674% of the total item variance contributing to the tool. CFA showed that the SPQ fit well. The total SPQ score was significantly associated with social network, quality of life, and cognitive function (r = |.180∼.466|, P < .001). The internal consistency coefficient was acceptable (range of Cronbach's alpha, .695 to .720).

CONCLUSIONS

The SPQ has robust properties, wide application, and provides a culturally relevant tool to evaluate the social participation of individuals, thus facilitating rigorous clinical and population-based research.

The Heterogeneity of Symptom Burden and Fear of Progression Among Kidney Transplant Recipients: A Latent Class Analysis

Purpose

Kidney transplant recipients (KTRs) may experience symptoms that increase their fear of progression (FoP), but a dearth of research examines the issue from a patient-centered perspective. Our study aimed to first determine the category of symptom burden, then to explore the differences in characteristics of patients in different subgroups, and finally to analyze the impact of symptom subgroup on FoP.

Patients and Methods

Sociodemographic and Clinical Characteristics, Symptom Experience Scale, and Fear of Progression Questionnaire-Short Form were used. Latent class analysis was used to group KTRs according to the occurrence of symptoms. We used multivariate logistic regression to analyze the predictors of different subgroups. The differences in FoP among symptom burden subgroups were analyzed by hierarchical multiple regression.

Results

Three subgroups were identified, designated all-high (20.5%), moderate (39.9%), and all-low (39.6%) according to their symptom occurrence. Multivariate logistic regression showed that gender, post-transplant time, per capita monthly income, and hyperuricemia were the factors that distinguished and predicted the all-high subgroup (P < 0.05). Hierarchical multiple regression showed that symptom burden had a significant effect on FoP (class1 vs class3: β = 0.327, P < 0.001; class2 vs class3: β = 0.104, P = 0.046), explaining the 8.0% variance of FoP (ΔR2 = 0.080).

Conclusion

KTRs generally experience moderate or low symptom burden, and symptom burden is an influencing factor in FoP. Identifying the traits of KTRs with high symptom burden can help clinicians develop targeted management strategies and ease FoP of KTRs.

Sickness Symptoms in Kidney Transplant Recipients: A Scoping Review

Sickness symptoms (depressive symptoms, anxiety, and fatigue) are common among people with chronic illness, often presenting as a symptom cluster. Sickness symptoms persist in many patients with chronic kidney disease, even after kidney transplantation (KT); however, little is known about sickness symptom-induced burden in KT recipients. This scoping review synthesizes available evidence for sickness symptoms in KT recipients, including findings on symptom prevalence, predictors, outcomes, interrelationships, and clustering. Among 38 reviewed studies, none identified sickness symptoms as a cluster, but we observed interrelationships among the symptoms examined. Fatigue was the most prevalent sickness symptom, followed by anxiety and depressive symptoms. Predictors of these symptoms included demographic, clinical, and psychosocial factors, and health-related quality of life was the most researched outcome. Future research should use common data elements to phenotype sickness symptoms, include biological markers, and employ sophisticated statistical methods to identify potential clustering of sickness symptoms in KT recipients.

Association Between the Fatigue and Sleep Quality of Kidney Transplant Recipients: The Mediating Role of Rumination

ABSTRACT

Sleep disorders persist in renal transplant patients. Previous studies have showed that fatigue and rumination are an important determinant of sleep quality. However, very few studies have explored the mediating role of rumination in the relationship between fatigue and sleep quality in kidney transplant recipients. A descriptive cross-sectional research design was implemented, and 192 kidney transplant patients completed the short questionnaire about their recent experiences of fatigue, rumination, and sleep quality. The prevalence of sleep disorders among kidney transplant recipients was 19.3%. With rumination as a partial mediator, fatigue indirectly affected the patients' sleep quality. This indirect effect was 0.10 (95% confidence interval, 0.154-0.419). Our results indicate that the incidence of sleep disorders after renal transplantation was high, and the more tired kidney transplant recipients become, the more likely they are to ruminate, which leads to a decline in sleep quality.

Nutrition Impact Symptom Clusters in a Cohort of Indigenous Australian Hemodialysis Patients: New Insights Into the Management of Malnutrition?

OBJECTIVE

The objective of this study is to describe nutrition impact symptom clusters present in a large sample of indigenous hemodialysis patients.

DESIGN AND METHODS

This study is a cross-sectional secondary analysis of data from a service audit conducted in 2016. All participants were hemodialysis patients from 2 satellite hemodialysis units in Central Australia. All participants completed a Patient-Generated Subjective Global Assessment. Exploratory factor analysis was performed to identify nutrition impact symptom clusters.

RESULTS

A total of 249 patients were included, representing 16% of all indigenous dialysis patients in Australia. Malnutrition was present in 29% of the sample. Five distinct nutrition impact symptom clusters were identified, accounting for 51.942% of the variance in symptoms. The 5 clusters extracted were the following: sore mouth (swallow problems, sore mouth, pain); nausea and vomiting (nausea, vomiting, taste changes); abnormal bowels (diarrhea, constipation, depression); anorexia (no appetite, early satiety); and dry mouth (dry mouth, dental problems).

CONCLUSIONS

Malnourished patients experienced a significantly greater symptom burden in this study. This analysis extends the small evidence base about the nutrition impact symptom burden of indigenous hemodialysis patients. Understanding symptom clusters and how symptoms are connected may be useful for triaging care and managing malnutrition.
