Abstract Purpose Between 15 and 30% of all nosocomial bacteremias and sepsis are associated with the use of intravascular devices. Catheter-related bloodstream infections (CRBI) are infections in which the organism identified in the blood is also present on the tip of the catheter itself or in a blood sample taken through it. The aim of the study was to evaluate the role of ultrasound in the diagnosis of infections related to the use of central catheters. Methods Between January 2018 and June 2019, we carried out a prospective study on 36 patients with a central catheter, such as a central venous catheter (CVC), a central catheter with peripheral insertion (PICC), or a fully implanted central venous catheter (PORT-a-cath) and who had signs and symptoms of infection. These patients were submitted to an ultrasound of the catheter upon arrival in the ward in case of suspected infection, or at the time of the onset of signs and symptoms of infection (if these arose during hospitalization). Patients with a central catheter but without signs and symptoms of infection were not included in the study. The end point of the study was to evaluate sensitivity (SENS), specificity (SPEC), positive and negative predictive value (PPV-NPV) and overall diagnostic accuracy (ODA) of ultrasound in the diagnosis of CRBI through Receiver Operating Characteristic (ROC) curve analysis. Results US showed a SENS of 94%, a SPEC of 84%, a PPV of 84%, an NPV of 94% and an ODA of 88.8% for the diagnosis of CRBI. Conclusions Preliminary data from our study show that US of intravascular devices has a high SENS and SPEC in the diagnosis of CRBI, and can, therefore, be used as a valid tool to decide whether to remove the device early or leave it in place.

<p><strong>Introduction:</strong> The objective of the study was to reduce, by a bundle of interventions, the global bloodstream infections and catheterrelated bloodstream infections rates in neutropenic hematology patients with a long-term central venous catheter.<br /><strong>Material and Methods:</strong> This was a non-randomized prospective study. It was conducted in a 20-bed hematology oncology unit (Portuguese Institute of Oncology, Porto, Portugal) between 1st of August 2010 and 31st of January 2012. In this period we introduced a bundle of interventions (study group) and compared the results with the six months prior to implementation (control group). The interventions consisted in the use of a neutral pressure mechanical valve connector instead of a positive pressure mechanical valve connector, a more frequent change of this connector and a more efficient clean solution. One hundred and sixteen hematology patients with a long-term central venous catheter at time superior of 72 h, with 8 867 central venous catheter days [6 756 central venous catheter days in the study group and 2 111 central venous catheter days in the control group] were included in the study.<br /><strong>Results:</strong> A significant reduction in bloodstream infections rates and catheter-related bloodstream infections rates was achieved. Bloodstream infections rates: [32.69 (control group) vs. 9.43 (study group)], incidence reduction 71% [relative risk 0.2886, CI 95% (0.1793 – 0.4647), p &lt; 0.001] and catheter-related bloodstream infections rates: [17.53 (control group) vs. 4.73 (study group)], incidence reduction 71% [relative risk 0.2936, CI 95% (0.1793 – 0.5615), p &lt; 0.014]. No significant difference (p &gt; 0.05) was found in the neutrophil count at the time of blood culture samples between groups: 69% (&lt; 500 neutrophils/mm3) [71% (study group) vs. 68% (control group)].<br /><strong>Conclusions:</strong> The introduction of this bundle of interventions based on the variables of patient, product and practice, supported by the Healthcare and Technology Synergy framework, quickly resulted in a significant reduction of bloodstream infections and catheterrelated bloodstream infections rates.</p>

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.
