Symptom cluster among hemodialysis patients in Taiwan.

This cross-sectional study aimed to investigate the prevalence and severity of symptom disturbance and to identify symptom clusters among hemodialysis patients. A convenience sample of 117 Taiwanese dialysis patients completed the Somatic Symptoms Disturbance Index, the Taiwanese Depression Scale, and a demographic questionnaire. Findings indicated that four symptom clusters emerged from the factor analysis. Relationships within symptom clusters were offered and explored.
