AbstractStudies published between 1999 and 2011 demonstrated increased blood culture contamination with catheter-drawn cultures compared with percutaneously-drawn cultures. Studies published between 2012 and 2015 reported that use of antiseptic barrier caps on central venous catheter hubs significantly reduces the incidence of catheter-drawn blood culture contamination. Local guidelines regarding sites for blood culture collection should reflect institution-level blood culture contamination rates for percutaneously-drawn and catheter-drawn cultures using currently available technologies that reduce contamination at both sites.

Period Data

To diagnose catheter-related sepsis without removing the catheter, we evaluated the differential positivity times of cultures of blood drawn simultaneously from central venous catheter and peripheral sites. In a 450-bed cancer reference center, simultaneous central- and peripheral-blood cultures were prospectively performed for patients with suspicion of catheter-related sepsis over an 18-month period. Data for 64 patients for whom the same microorganisms were found when central- and peripheral-blood samples were cultured were retrospectively reviewed by two independent physicians blinded to the differential positivity time values in order to establish or refute the diagnosis of catheter-related sepsis. The diagnosis was established in 28 cases, refuted in 14, and indeterminate in the remaining 22. The differential positivity time was significantly greater for patients with catheter-related sepsis (P < 10−4). A cutoff limit of +120 min had 100% specificity and 96.4% sensitivity for the diagnosis of catheter-related sepsis. These results strongly suggest that measurement of the differential positivity time might be a reliable tool facilitating the diagnosis of catheter-related sepsis in patients with an indwelling catheter.

Haematological Patients

Catheter-related bloodstream infection (CRBSI) caused by coagulase-negative staphylococci (CNS) is common in haematological patients with febrile neutropenia. As the clinical signs of CRBSI are usually scarce and it is difficult to differentiate from blood culture contamination, we tried to confirm CRBSI by molecular typing of CNS isolated from paired blood cultures (one from a peripheral vein and another from the central venous catheter hub). Blood cultures were positive in 59 (36%) out of 163 patients. CNS were isolated in 24 (40%) patients; in 14 from paired blood cultures (28 isolates) and in 10 from a single blood culture. CNS from paired blood cultures were identified as Staphylococcus epidermidis. Antimicrobial susceptibility was determined and bacteria were typed by pulsed-field gel electrophoresis (PFGE) of bacterial genomic DNA. In 13 patients, the antibiotic susceptibility of isolates was identical. The PFGE patterns from paired blood cultures were identical or closely related in 10 patients, thus confirming the presence of CRBSI. In the remaining four patients they were unrelated, and suggested a mixed infection or contamination. Since CNS isolates from three patients had identical PFGE patterns, they were probably nosocomially spread amongst them.

ABSTRACT Objectives: to establish the prevalence of salvage of central venous catheters in newborns with bloodstream infection caused by coagulase-negative staphylococci. Methods: retrospective cross-sectional study with 136 newborns admitted to the Neonatal Intensive Care Unit between 2011 and 2017. The total of 143 infection events undergoing antibiotic therapy were evaluated. Results: among the 143 infection events, 39 catheters in which antibiotic therapy was used were saved and in 69 cases, the device was removed. Positive central blood culture and single lumen catheter were factors associated with salvage failure. The probability of salvage decreased with infections diagnosed from 15 days of using the catheter. Negative blood culture raised the chance of salvage by fourfold. Conclusions: the use of antibiotic therapy in the treatment of infections resulted in a low prevalence of salvage of the central venous catheter. The probability of salvage was associated with variables of the device.

Abstract Background Candida is the most common cause of invasive fungal infection in healthcare settings and is associated with significant increases in healthcare resource utilization and attributable mortality. Methods This study was conducted in a pediatric tertiary care hospital from Turkey. We conducted a retrospective analysis in children ≤18 years with blood culture-proven candidaemia identified between December 2013 and November 2017. Sociodemographic variables,underlying condition, mortality, additional risk factors, origin of specimens were all recorded. Results A total of 236 episodes of candidaemia were identified over the study period. The median age of the patients was 600 days (4-6482). 106 specimens (44.9%) were cultured from patients under 1 year of age and 15 of 106 specimens were cultured from neonates. The most frequently isolated Candida spp. were C. albicans (42.%), followed by C. parapsilosis (30.5%), C. glabrata (7.6%), C. tropicalis (6.4%), C. krusei (2.5%), C. lusitaine (2.5%), C. dubliniensis (2.1%), C. kefir (0.8%), and C. pelliculosa (0.4%). In 11 of the 236 episodes (4.5%), two Candida spp were cultured at the same time.The most common coinfection was C. albicans and C. parapsilosis. 112 of the 236 episodes (47.5%) was due to central venous catheter-related blood stream infection. 47.5% of these patients were receiving total parenteral nutrition at the time of candidemia. Concomitant coagulase negatif staphylococcus bacteremia was present in 50 of 236 candidemia episodes (21.2%). Of 236 isolates, 74 (31.4%) was cultured from peripheral blood culture only, 95 (40.3%) from central venous catheter only, 67 (28.4%) from both peripheral and central catheter blood culture.Trombocytopenia was noted in 117 episodes (49.6%) and neutropenia in 45 episodes (19.1 Of the 112 central venous catheter-related candidemia, 35 (31.3%) resulted in death within 30 days from the onset of candidaemia (Figure 1). In 49 (45.%) episodes of central venous catheter-related candidemia, catheter was not removed and 40% of these episodes resulted as death.Catheter removal, thrombocytopenia, total parenteral nutrion were found to be associated with increased mortality in children under 1 year of age (P < 0.001). Conclusion Clinicians must be aware of candidemia in children due to high risk of mortality. Disclosures All authors: No reported disclosures.
