Abstract
BACKGROUND: Patients receiving renal dialysis often experience a wide range of symptoms. These symptoms contribute to a significant symptom burden that significantly affects patients' quality of life and serves as a significant predictor of healthcare resource utilization and patient prognosis. It is necessary to synthesize existing evidence to draw reliable conclusions to deepen the understanding of symptom burden. OBJECTIVE: A systematic review and meta-analysis were conducted to identify the relevant factors of symptom burden in patients receiving renal dialysis. METHODS: The systematic review and meta-analysis was conducted by searching nine databases for studies reporting the correlates between symptom burden and demographic variables, disease factors, and psychosocial factors from inception to 24 June 2024. After two researchers independently conducted literature search, data extraction, and quality evaluation, meta-analysis was conducted using R Language and Stata 15.1 Software. This study has been registered in the PROSPERO. RESULTS: Sixty-two studies were included in this review. Results showed that the symptom burden of renal dialysis patients was positively correlated with age, gender, working status, medical cost, dialysis age, quality of sleep, nutritional status, comorbidities, depression, anxiety, disease uncertain, avoidance coping and resignation coping, and negatively correlated with marital status, income, serum sodium, quality of life, social support, subjective well-being, and self-management ability. CONCLUSIONS: CRD42024507577.
