摘　　要：Importance:Central line-associated bloodstream infection(CLABSI)is one of the most serious complications of central venous access devices.Reducing the risk of CLABSI is of utmost significance in efforts to improve neonatal mortality rates and enhance long-term prognosis.Objective:To determine the dwell time and incidence of CLABSI of umbilical venous catheterization(UVC)for preterm infants in China.Methods:Preterm infants with UVC admitted to 44 tertiary neonatal intensive care units in 24 provinces in China were enrolled.Study period was from November 2019 to August 2021.The end point of observations was 48 h after umbilical venous(UV)catheter removal.The primary outcomes were dwell time of UV catheter and UVC-associated CLABSI.Data between infants with UV catheter dwell time≤7 days and>7 days,and with birth weight(BW)≤1000 g and>1000 g were compared.Results:In total,2172 neonates were enrolled(gestational age 30.0±2.4 weeks,BW 1258.5±392.8 g).The median UV catheter dwell time was 7(6–10)days.The incidence of UVC-associated CLABSI was 3.03/1000 UV catheter days.For infants with UV catheter dwell time≤7 days and>7 days,the UVC-associated CLABSI incidence was 3.71 and 2.65 per 1000 UV catheter days,respectively,P=0.23.For infants with UVC dwell times of 3–6,7–12,and 13–15 days,the UVC-associated CLABSI rates were 0.14%,0.68%,and 2.48%(P<0.01).The Kaplan–Meier plot of UV catheter dwell time to CLABSI showed no difference between infants with BW≤1000 g and>1000 g(P=0.60).Interpretation:The median dwell time of UV catheter was 7 days,and the incidence of UVC-associated CLABSI was 3.03/1000 catheter days in China.The daily risk of UVC-associated CLABSI and other complications increased with the dwell time.
