Background Sepsis is a complication frequently encountered in children with underlying malignancies, especially due to a majority of patients having indwelling venous catheters. Indications for catheter removal among children with central-line associated blood stream infection (CLABSI) should follow the recommendations for adults, however, difficulties in vascular access often leads to attempting treatment without catheter removal. Therefore, the primary aim of this study was to find risk factors for recurrent sepsis in children undergoing chemotherapy of HSCT and examine whether more aggressive catheter removal after CLABSI in children is necessary. Methods In the Pediatric Bone Marrow Transplant Center of Seoul St. Mary’s Hospital, positive blood cultures were prospectively monitored to control and prevent outbreaks. The date of culture, culture results, symptoms presented, category of blood stream infections (by the CDC/NHSN surveillance definition (2021) of Bloodstream infections), and central-line associated blood stream infection (CLABSI) events were monitored. Results During September 2016 to February 2021, a total 280 cases of laboratory confirmed bloodstream infections (LCBI) or Mucosal Barrier Injury LCBI (MBI-LCBI) were diagnosed in children < 18 years old with underlying malignancies. Of these, 52.9% (n=148) were male, and the mean age was 9.7 (SD±6.1) years old. CLABSI was diagnosed in 51.8% (n=145), and the most common pathogens cultured were S. mitis/oralis (24.0%, n=67), E. coli (15.4%, n=43), and coagulase negative Staphylococci (CNS) (10.4%, n=29). Recurrent sepsis occured in 17.1% (n=48), and 9.6% (n=27) had two indwelling catheters . Multivariable analysis showed that factors associated with recurrent blood stream infections were as follows: duration of indwelling catheter (OR, 1.002; 95% CI, 1.001-1.004; P< 0.001) and no removal of central lines after previous episode (OR, 51.143; 95% CI, 6.6-395.0; P< 0.001). Conclusion Permanent central lines should be removed as soon as possible, and more aggressive approach in permanent catheter removal after LCBSIs in children is necessary to reduce recurrent infections.
