Factors influencing catheter-related infections in peritoneal dialysis patients: a meta-analysis

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.
