Background: Bloodstream infection (BSI) is the most challenging conditions in patients who undergo hematopoietic stem cell transplantation (HSCT). These infections may be related to health care in cases of central-line–associated bloodstream infection (CLABSI) or to translocation secondary to mucosal barrier injury (MBI). In 2013, MBI surveillance was incorporated into the CDC NHSN. The aim was to increase the CLABSI diagnostic accuracy by proposing more effective preventive care measures. The objective of this study was to evaluate impact of the MBI surveillance on CLABSI incidence density in a Brazilian university hospital. Methods: The CLABSI incidence densities from the period before BMI surveillance (2007–2012) and the period after BMI surveillance was implemented (2013–2018) were analyzed and compared. Infections during the preintervention period were reclassified according to the MBI criterion to obtain an accurate CLABSI rate for the first period. The average incidence densities for the 2 periods were compared using the Student t test after testing for no autocorrelation (P > .05). Results: After reclassification, the preintervention period incidence density (10 infections per 1,000 patient days) was significantly higher than the postintervention period incidence density (6 infections per 1,000 patients day; P = .011) (Table 1). Therefore, the reclassification of nonpreventable infections (MBI) in the surveillance system made the diagnosis of CLABSI more specific. The hospital infection control service was able to introduce specific preventive measures related to the insertion and management of central lines in HSCT patient care. Conclusions: The MBI classification improved the CLABSI diagnosis, which upgraded central-line prevention measures, then contributed to the decrease of CLABSI rates in this high-risk population.Funding: NoneDisclosures: None

Abstract Background NHSN Mucosal Barrier Injury-Laboratory Confirmed Bloodstream Infection (MBI-LCBI) includes pathogens likely to cause bloodstream infections (BSI) in some oncology patients. MBI-LCBIs are excluded from central line-associated BSI (CLABSI) reporting to the Centers for Medicare & Medicaid Services. NHSN users have requested other pathogens be added to MBI-LCBI. To make decision, we compared CLABSI pathogen distributions in three NHSN patient location groups. Methods We analyzed CLABSI data from hospitals conducting surveillance for ≥ 1 month from January 2014–December 2018 in ≥ 1 MBI high-risk location (leukemia, lymphoma, and adult and pediatric hematopoietic stem cell transplant wards). We compared CLABSI pathogen distributions and rates in MBI high-risk locations to medium-risk (solid tumor, adult and pediatric general hematology-oncology wards) and low-risk locations (adult and pediatric medical, surgical, and medical-surgical wards), and used χ2 tests to compare percentages with statistical significance at P ≤ 0.05. Results Overall, 122 hospitals reported 23,578 CLABSIs and 12,961,921 central line (CL)-days (1.81 CLABSIs per 1,000 CL-days) (Table). Percentages of CLABSIs due to three MBI-LCBI pathogens (E. coli, E. faecium, Viridans streptococci) were significantly higher in high- versus low-risk locations, while for other MBI-LCBI pathogens (K. pneumoniae/oxytoca, E. faecalis, Candida spp., Enterobacter spp.) percentages were significantly lower in high-risk locations (Figure). For pathogens not currently in MBI-LCBI, coagulase-negative staphylococci caused similar percentages of CLABSIs across locations, S. aureus caused a significantly higher percentage of CLABSIs in low-risk locations, while PA caused a significantly higher percentage of CLABSIs in high-risk locations. Table CLABSIs attributed to MBI high-risk, medium-risk, and low-risk locations, NHSN, 2014–2018 Figure Percentages of top 10 pathogen-specific CLABSIs in MBI high-risk, medium-risk, and low-risk locations, NHSN, 2014–2018 Conclusion Differences in percentages of CLABSIs due to selected pathogens between MBI high-risk and low-risk locations are evident in NHSN data. Lower percentages of Klebsiella and Candida spp. in high-risk locations might be partially due to antimicrobial prophylaxis in oncology patients. Although PA caused a significantly higher percentage of CLABSIs in high-risk locations, the absolute difference was modest. Additional analyses are needed.

Abstract Objective Gram-negative organisms have become a major etiology of bloodstream infections. We evaluated the effect of central venous catheter management on cancer patients with gram-negative bloodstream infections. Method We retrospectively identified patients older than 14 years with central venous catheters who were diagnosed with gram-negative bloodstream infections to determine the effect of catheter management on outcome. Patients were divided into 3 groups: Group 1 included patients with central line-associated bloodstream infections (CLABSI) without mucosal barrier injury and those whose infection met the criteria for catheter-related bloodstream infection; group 2 included patients with CLABSI with mucosal barrier injury who did not meet the criteria for catheter-related bloodstream infection; and group 3 included patients with non-CLABSI. Results The study included 300 patients, with 100 patients in each group. Only in group 1 was central venous catheter removal within 2 days of bloodstream infection significantly associated with a higher rate of microbiologic resolution at 4 days compared to delayed central venous catheter removal (3–5 days) or retention (98% vs 82%, P = .006) and a lower overall mortality rate at 3-month follow-up (3% vs 19%, P = .01). Both associations persisted in multivariate analyses (P = .018 and P = .016, respectively). Conclusions Central venous catheter removal within 2 days of the onset of gram-negative bloodstream infections significantly improved the infectious outcome and overall mortality of adult cancer patients with catheter-related bloodstream infections and CLABSI without mucosal barrier injury.
