Outcomes in Pediatric Central Line-associated Bloodstream Infections Treated With Antimicrobial Locks: A 14-year Retrospective Analysis

Salvage strategy for long-term central venous catheter-associated Staphylococcus aureus infections in children: a multi-centre retrospective study in France

OBJECTIVES

Catheter removal is recommended in adults with Staphylococcus aureus central-line-associated bloodstream infection (CLABSI) but is controversial in children with long-term central venous catheters (LTCVC). We evaluated the occurrence of catheter salvage strategy (CSS) in children with S. aureus LTCVC-associated CLABSI and assessed determinants of CSS failure.

METHODS

We retrospectively included children (<18 years) with an LTCVC and hospitalized with S. aureus CLABSI in eight French tertiary-care hospitals (2010-2018). CSS was defined as an LTCVC left in place ≥72 h after initiating empiric antibiotic treatment for suspected bacteraemia. Characteristics of patients were reviewed, and multi-variable logistic regression was performed to identify factors associated with CSS failure (i.e., persistence, recurrence or complications of bacteraemia).

RESULTS

We included 273 episodes of S. aureus LTCVC-associated CLABSI. CSS was chosen in 194 out of 273 (71%) cases and failed in 74 of them (38%). The main type of CSS failure was the persistence of bacteraemia (39 of 74 cases, 53%). Factors independently associated with CSS failure were: history of catheter infection (adjusted odds ratio (aOR) 3.18, 95% confidence interval (CI) 1.38-7.36), CLABSI occurring on an implantable venous access device (aOR 7.61, 95% CI 1.98-29.20) when compared with tunnelled-cuffed CVC, polymicrobial CLABSI (aOR 3.45, 95% CI 1.25-9.50), and severe sepsis at the initial stage of infection (aOR 4.46, 95% CI 1.18-16.82).

CONCLUSIONS

CSS was frequently chosen in children with S. aureus LTCVC-associated CLABSI, and failure occurred in one-third of cases. The identified risk factors may help clinicians identify children at risk for CSS failure.

Consensus document of the Spanish Society of Paediatric Infectious Diseases (SEIP) and the Spanish Society of Paediatric Intensive Care (SECIP) for the diagnosis and treatment of central venous catheter-related infections in paediatric care

Intravascular devices are essential for the diagnostic and therapeutic approach to multiple diseases in paediatrics, and central venous catheters (CVCs) are especially important. One of the most frequent complications is the infection of these devices, which is associated with a high morbidity and mortality. These infections are highly complex, requiring the use of substantial resources, both for their diagnosis and treatment, and affect vulnerable paediatric patients admitted to high-complexity units more frequently. There is less evidence on their management in paediatric patients compared to adults, and no consensus documents on the subject have been published in Spain. The objective of this document, developed jointly by the Spanish Society of Paediatric Infectious Diseases (SEIP) and the Spanish Society of Paediatric Intensive Care (SECIP), is to provide consensus recommendations based on the greatest degree of evidence available to optimize the diagnosis and treatment of catheter-related bloodstream infections (CRBSIs). This document focuses on non-neonatal paediatric patients with CRBSIs and does not address the prevention of these infections.

Peripherally inserted central catheter securement with cyanoacrylate glue and bloodstream infection: A retrospective cohort study

BACKGROUND

Treatment via a peripherally inserted central venous catheter is important for anticancer treatment, perioperative management, and nutrition management. In this study, we aimed to investigate the usefulness of cyanoacrylate glue (CG) in managing peripherally inserted central venous catheters in adults.

METHODS

This retrospective cohort study enrolled 411 adults requiring a central venous catheter for treatment in the Chiba University Esophageal-Gastro-Intestinal Surgery department between January 2021 and October 2022. The preventive effect of CG in reducing adverse events, including infection, tip migration, and thrombus formation, was evaluated by reviewing electronic medical records, chest radiographs, and contrast-enhanced computed tomography scans.

RESULTS

CG and other dressings were used in 158 (CG group) and 253 (control group) patients, respectively. The incidence of catheter infection based on the clinical course was lower in the CG group (3.2%) than in the control group (9.1%; P = 0.03). However, cases of infection confirmed by blood or catheter cultures did not differ between the CG (1.3%) and control (1.9%) groups (P = 1.0). Chest radiographs revealed that catheter tip migration (mean ± SD) was lesser in the CG group (8.2 ± 6.7 mm) than in the control group (15.0 ± 15.8 mm; P < 0.01). There were two cases of venous thrombus formation in the control group.

CONCLUSION

In a population dominated by esophago-gastroenterological malignancy, peripherally inserted central catheter securement via CG was associated with decreased catheter removal because of suspected catheter infection. Further research on larger cohorts is needed to determine if other adverse events decrease following peripherally inserted central catheter securement via CG.
