Risk factors for catheter-associated bloodstream infection in hemodialysis patients: A meta-analysis
Abstract
Objective This meta-analysis aimed to elucidate the risk factors contributing to catheter-associated bloodstream infection in hemodialysis patients. Methods Comprehensive literature searches were conducted in both English and Chinese databases, which encompassed PubMed, Cochrane Library, Embase, CNKI, Wanfang Data, VIP Database and China Biomedical Literature Database. The search timeframe extended from each database’s inception to March 8, 2023. Two independent researchers executed literature screening, data extraction, and quality assessment using the Newcastle-Ottawa Scale. Statistical analysis of the data was performed using RevMan 5.3 software, facilitating the identification of significant risk factors associated with catheter-related bloodstream infections in hemodialysis patients. This meta-analysis is registered with PROSPERO under the registration number CRD42023406223. Results Forty-nine studies were incorporated into this meta-analysis, from which 22 risk factors were examined. Through the analysis, 17 risk factors exhibited statistical significance (P < 0.05): age (OR = 1.52, 95% CI [0.49, 4.68]), diabetes (OR = 2.52, 95% CI [1.95, 3.25]), kidney disease (OR = 3.45, 95% CI [1.71, 6.96]), history of catheter-associated infection (OR = 2.79, 95% CI [1.96, 3.98]), hypertension (OR = 1.43, 95% CI [1.08, 1.91]), dialysis duration (OR = 3.06, 95% CI [1.70, 5.50]), catheter placement site (OR = 1.91, 95%CI [1.35, 2.70]), catheter duration (OR = 2.06, 95% CI [1.17,…
