신생아 중환자실에서의 중심정맥관 관련 감염의 역학: 신속 체계적 고찰

초록

Background: Catheter-related bloodstream infections (CRBSIs) are serious complications in neonatal intensive care units (NICUs). We aimed to assess the incidence of CRBSIs in NICUs worldwide and describe the causative organisms. Methods: We searched PubMed, EMBASE, Cochrane, and KoreaMed databases. We included studies on CRBSIs in NICU settings with data on bacteremia. We performed a random-effects meta-analysis on CRBSI incidence in NICUs, stratified the data according to WHO regions. We compiled data on underlying organisms. Results: Of the 692 studies identified, 71 published between 2011 and 2022 were considered eligible. The pooled incidence of CRBSI per 1000 catheter days in NICUs was 8.66 (95% confidence interval [CI], 7.19; 10.12). Stratifying by WHO regions, the CRBSI incidence per 1000 catheter days was 10.38 (95% CI, 3.86; 16.90) in the Eastern Mediterranean Region (EMR), 11.77 (95% CI, 9.20; 14.35) in the European Union Region (EUR), 5.94 (95% CI, 3.87; 8.00) in the Western Pacific Region (WPR), and 6.71 (95% CI, 4.39; 9.03) in the Region from the Americas (AMR). Of the 2887 bacterial strains, 73.4% (n=2118) were gram-positive bacteria, 18.9% (n=547) were gram-negative bacteria, and 7.8% (n=225) were fungi. Coagulasenegative Staphylococci (n=1380, 65.2%) were the most common pathogen among the grampositive types, followed by Staphylococcus aureus (n=318, 15%). Among the CRBSI gramnegative cultures, Klebsiella spp. (n=201, 36.7%) was the primary pathogen. Conclusion: We found a substantial burden of CRBSIs in NICUs across the globe. Our findings highlight the need to improve the implementation of global and local strategies to reduce CRBSIs in NICUs.
