Through a cross-sectional questionnaire survey, a general information questionnaire and Dialysis Frequency, Severity, and Symptom Burden Index were used to investigate the frequency, severity, and degree of symptom distress in MHD patients, and to analyze the differences in symptom distress status between long and short dialysis age MHD patients. Using the R 4.2.2 software qgraph package, construct symptom networks for MHD patients of long and short dialysis age through network analysis. Analyze network centrality indicators, including intensity, closeness centrality, and mediation centrality, to identify core symptoms and compare if there are any differences between the two groups, aiming to lay the foundation for precise and efficient phased symptom management.
