Abstract
OBJECTIVE: Systematic analysis of factors influencing catheter-related infections in patients undergoing peritoneal dialysis. METHODS: A computerized search of Chinese and English databases was conducted to identify the factors affecting catheter-related infections in patients undergoing peritoneal dialysis. Studies with a search period from inception to July 31, 2024 were retrieved. Two researchers independently screened the literature using inclusion and exclusion criteria, and data extraction and quality assessments were performed. Meta-analysis was performed using RevMan5.4 and Stata software. RESULTS: In total, 13 studies were included and meta-analysis revealed that comorbid diabetes mellitus, insecure catheter fixation, dialysis duration >2 years, body mass index >20 kg/m(2), mechanical strain, lack of proper care, irregular caregivers, and history of catheter pulling (P < 0.05) were the influencing factors contributing to the incidence of catheter-related infections in patients undergoing peritoneal dialysis. CONCLUSIONS: Clinicians should pay close attention to these influencing factors and provide targeted preventive measures to prevent catheter-related infections.
