The Influence of Caregiver Contribution to Self-care on Symptom Burden in Patients With Heart Failure and the Mediating Role of Patient Self-care: A Longitudinal Mediation Analysis

The Effect of Heart Failure Symptom Clusters on Quality of Life: The Moderating Effect of Self-Care Behaviours

BACKGROUND

Although heart failure (HF) symptoms affect patients' quality of life (QoL), improving patients' QoL requires certain self-care behaviours. However, the specific role of self-care behaviours in the relationship between HF symptoms and QoL has not been clarified.

AIMS

To evaluate the status of symptom clusters, self-care behaviours and QoL in HF patients, and to analyse and test the moderating effect of self-care behaviours between symptom clusters and QoL.

DESIGN

This study is a cross-sectional study.

METHODS

A total of 320 HF patients who treated in the three hospitals in Chengdu, China, from December 2022 to July 2023 were selected as the research subjects. The patients were evaluated using The General Information Questionnaire, Memorial Symptom Assessment Scale Heart Failure, Self-Care of Heart Failure Index and Minnesota Living with Heart Failure Questionnaire. The statistical analysis methods were exploratory factor analysis, Pearson correlation analysis, hierarchical regression analysis and simple slope analysis.

RESULTS

There were five symptom clusters in HF patients: emotional symptom cluster (sadness, anxiety, irritability, feeling nervous), digestive symptom cluster (lack of appetite, dry mouth, weight loss, nausea, abdominal distension), ischemic symptom cluster (dizziness, chest pain, palpitations, fatigue), dyspnoea symptom cluster (difficulty breathing when lying flat, waking up breathless at night, sleep difficulty) and congestion symptom cluster (cough, shortness of breath, oedema). There was a significant correlation between HF symptom group, self-care behaviours and QoL (p < 0.05). Both self-care maintenance (β = -0.262, p < 0.001) and self-care management (β = -0.258, p < 0.001) had a moderating effect between symptom clusters and QoL.

CONCLUSION

There are a variety of symptom clusters in HF patients. Improving the self-care behaviours ability of HF patients is conducive to reducing the impact of HF symptom clusters on QoL.

REPORTING METHOD

The study used the STROBE checklist for reporting.

RELEVANCE TO CLINICAL PRACTICE

Medical staff should focus on the impact of HF symptom clusters and self-care behaviours on QoL, and formulate corresponding interventions for HF symptom clusters and self-care behaviours to improve the QoL of patients.

PATIENT OR PUBLIC CONTRIBUTION

The head nurse of the cardiovascular department actively assisted us in collecting questionnaires from HF patients, and all HF patients surveyed participated in this study seriously.

Determinants of preparedness in family caregivers of patients with heart failure

AIMS

Inadequate preparedness of family caregivers contributes to adverse outcomes of patients with heart failure (HF). However, evidence on caregiver preparedness is limited. This study aims to examine the determinants and potential mechanisms of preparedness in family caregivers of patients with HF.

METHODS AND RESULTS

In the cross-sectional study, 298 HF patient-caregiver dyads were recruited from 4 tertiary hospitals in China. Preparedness, uncertainty in illness, family relational quality, social support, and positive aspects of caregiving (PAC) were assessed in family caregivers using self-reported questionnaires. In the path analysis model, uncertainty in illness had an indirect negative effect on preparedness via reduced PAC [indirect effect = -0.020; 95% confidence interval (CI) -0.050 to -0.002]. Whereas, family relational quality had direct (β = 0.266; P < 0.001) and indirect positive effects on preparedness through increased PAC (indirect effect = 0.027; 95% CI, 0.003-0.067). Similarly, social support also had direct (β = 0.184; P = 0.004) and indirect positive effects on preparedness through increased PAC (indirect effect = 0.027; 95% CI, 0.004-0.065).

CONCLUSION

This study highlights that diminishing uncertainty in illness may indirectly improve caregiver preparedness through the enhancement of PAC, while raising family relational quality and social support may improve caregiver preparedness both directly and indirectly by augmenting PAC. These findings provide insightful implications for healthcare professionals in developing tailored interventions to ameliorate preparedness in family caregivers of patients with HF.
