Effect of sutureless securement on hemodialysis catheter-related bloodstream infection

ABSTRACT: The use of sutureless securement devices during catheterization might reduce the risk of catheter-related bloodstream infection (CRBSI) by suppressing catheter-exit infection and catheter dislodgement. However, the effectiveness of these devices in reducing CRBSI risk when securing hemodialysis catheters has not been explored. This single-center retrospective observational study examined 211 non-tunneled hemodialysis catheters (NTHCs) from 110 hemodialysis inpatients, of which 121 were secured using conventional skin sutures (Suture group) and 90 with GRIP-LOK (GRIP-LOK group). The stabilized inverse probability of treatment (SIPT)-weighting method was used to generate a new population (SIPT-weighted model) without group differences for each of the 12 predictors of CRBSI development (i.e., age, sex, dialysis history, concomitant acute kidney injury or diabetes, concurrent use of immunosuppressant drugs or aspirin, NTHC insertion site, methicillin-resistant Staphylococcus aureus, carriage, bacteremia event within 3 months before catheterization, hemoglobin level, and serum albumin titer). The effect of GRIP-LOK compared with sutures on CRBSI in the SIPT-weighted model was evaluated using univariate SIPT-weighted Cox proportional regression analysis, which showed a significant CRBSI suppression effect of GRIP-LOK compared with sutures (hazard ratio: 0.17 [95% CI 0.04–0.78], p = 0.023).　GRIP-LOK affords a lower risk of CRBSI due to indwelling NTHCs than conventional securement using sutures.

Project description:Mycobacterium brumae is a rapidly growing environmental mycobacterial species identified in 1993; so far, no infections by this organism have been reported. Here we present a catheter-related M. brumae bloodstream infection in a 54-year-old woman with breast cancer. The patient presented with high fever (39.7 degrees C), and >1,000 colonies of M. brumae grew from a quantitative culture of blood drawn through the catheter. A paired peripheral blood culture was negative, however, suggesting circulational control of the infection. The patient was treated empirically with meropenem and vancomycin, and the fever resolved within 24 h. The catheter was removed a week later, and from the tip M. brumae was isolated a second time, suggesting catheter colonization. The organism was identified by colonial morphology, sequence analysis of the 16S rRNA gene, and biochemical tests.

Establishing catheter-related bloodstream infection surveillance to drive improvement.

Project description:BackgroundCatheter-related blood stream infections (CRBSI) are an important complication of central venous access devices but are often poorly measured. This article describes the journey of one hospital trust to set up a surveillance process for CRBSI across all specialties of the trust and to reduce CRBSI.MethodUsing a locally adapted CRBSI criteria and root cause analysis (RCA) for investigation we identified a number of opportunities for a quality improvement programme.FindingsOver a 5-year period we saw a significant and sustained reduction in the rate of CRBSI from 5 per 1000 catheter days to 0.23 per 1000 catheter days.ConclusionsThe surveillance enabled rates of CRBSI to be monitored across the trust and the success of our improvements to be measured.

Cluster-Randomized Trial of Devices to Prevent Catheter-Related Bloodstream Infection.

Project description:Central venous catheters (CVCs) contribute disproportionately to bloodstream infection (BSI) and, by extension, to infection-related hospitalization, mortality, and health care costs in patients undergoing dialysis. Recent product advancements may reduce BSIs, but a sufficiently powered comparative-effectiveness study is needed to facilitate evidence-based patient care decisions. In a 13-month, prospective, cluster-randomized, open-label trial, we compared BSI rates in facilities using ClearGuard HD antimicrobial barrier caps (ClearGuard group) with those in facilities using Tego hemodialysis connectors plus Curos disinfecting caps (Tego+Curos group). Forty DaVita dialysis facilities in the United States were pair-matched by BSI rate, number of patients using CVCs, and geographic location, and then cluster randomized 1:1. We enrolled all adult patients undergoing dialysis with CVCs at these facilities, except those allergic to heparin or chlorhexidine. Overall, 1671 patients participated in the study, accruing >183,000 CVC-days. The study outcome was positive blood culture (PBC) rate as an indicator of BSI rate. We calculated results at the cluster level and adjusted for the facility cluster effect. During a 3-month run-in period immediately before study interventions, the groups had similar BSI rates (P=0.8). During the 13-month intervention period that immediately followed, the ClearGuard group had a BSI rate significantly lower than that of the Tego+Curos group (0.28 versus 0.75 PBCs per 1000 CVC-days, respectively; P=0.001). No device-related adverse events were reported. In conclusion, compared with Tego connectors plus Curos caps, ClearGuard HD antimicrobial barrier caps significantly lowered the rate of catheter-related BSIs in patients undergoing hemodialysis using CVCs, representing an important advancement in hemodialysis patient care.

The first case of catheter-related bloodstream infection caused by Nocardia farcinica.

Project description:Nocardia farcinica is an emerging pathogen in immunocompromised hosts. Even though several species of Nocardia have been reported as causative pathogens of catheter-related blood stream infections (CRBSI), CRBSI caused by N. farcinica has not been reported. A 70-yr-old man with a tunneled central venous catheter (CVC) for home parenteral nutrition was admitted with fever for two days. Norcardia species was isolated from the blood through CVC and peripheral bloods and identified to N. farcinica by 16S rRNA and rpoB gene sequence analyses. This report emphasizes the rapid and correct identification of causative agents in infectious diseases in the selection of antimicrobial agents and the consideration of catheter removal.

Project description:Kodamaea ohmeri is a rare yeast pathogen that has recently emerged as an important cause of fungaemia in immunocompromised patients. In most cases, identification to the species level requires the adoption of new tools, including matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) or DNA sequencing. As K. ohmeri is a teleomorph of Candida guilliermondii var. membranaefaciens and its susceptibility to fluconazole is variable, a rapid and accurate identification of this yeast is important. Echinocandins may be the first choice for empiric therapy for this pathogen. We report the case of a 25-year-old male patient from North China who developed a catheter-related bloodstream infection caused by K. ohmeri. He was treated with caspofungin in hospital. He improved after removal of the central venous catheter and use of caspofungin as therapy. The K. ohmeri strain was identified using a MALDI-TOF mass spectrometer and a Vitek 2YST card. Definitive identification was obtained by a sequencing test of the internal transcribed spacer regions of the rDNA. Our patient findings, the first reported in mainland China, highlighted the diagnostic challenges associated with catheter-related bloodstream infection caused by fungi.

Lower risk of peripheral venous catheter-related bloodstream infection by hand insertion.

Project description:IntroductionLittle is known about the bloodstream infection (BSI) risk associated with short-term peripheral venous catheters (PVCs) and no large study investigated the insertion site-related risk for PVC-BSI.MethodsWe performed a cohort study at the University of Geneva Hospitals using the prospective hospital-wide BSI surveillance database. We analyzed the association between insertion site and risk of PVC-BSI on the upper extremity using univariable and multivariable marginal Cox models.ResultsBetween 2016 and 2020, utilization of 403'206 peripheral venous catheters were prospectively recorded in a 2000-bed hospital consortium with ten sites. Twenty-seven percent of PVC (n = 109'686) were inserted in the hand. After adjustment for confounding factors, hand insertion was associated with a decreased PVC-BSI risk (adjusted hazard ratio [HR] 0.42, 95% CI 0.18-0.98, p = 0.046) compared to more proximal insertion sites. In a sensitivity analysis for PVCs with ≥ 3 days of dwell time, we confirmed a decreased PVC-BSI risk after hand insertion (HR 0.37, 95% CI 0.15-0.93, p = 0.035).ConclusionHand insertion should be considered for reducing PVC infections, especially for catheters with an expected dwell time of more than 2 days.

Chlorhexidine-impregnated dressing for prevention of catheter-related bloodstream infection: a meta-analysis*.

Project description:ObjectiveTo assess the efficacy of a chlorhexidine-impregnated dressing for prevention of central venous catheter-related colonization and catheter-related bloodstream infection using meta-analysis.Data sourcesMultiple computerized database searches supplemented by manual searches including relevant conference proceedings.Study selectionRandomized controlled trials evaluating the efficacy of a chlorhexidine-impregnated dressing compared with conventional dressings for prevention of catheter colonization and catheter-related bloodstream infection.Data extractionData were extracted on patient and catheter characteristics and outcomes.Data synthesisNine randomized controlled trials met the inclusion criteria. Use of a chlorhexidine-impregnated dressing resulted in a reduced prevalence of catheter-related bloodstream infection (random effects relative risk, 0.60; 95% CI, 0.41-0.88, p = 0.009). The prevalence of catheter colonization was also markedly reduced in the chlorhexidine-impregnated dressing group (random effects relative risk, 0.52; 95% CI, 0.43-0.64; p < 0.001). There was significant benefit for prevention of catheter colonization and catheter-related bloodstream infection, including arterial catheters used for hemodynamic monitoring. Other than in low birth weight infants, adverse effects were rare and minor.ConclusionsOur analysis shows that a chlorhexidine-impregnated dressing is beneficial in preventing catheter colonization and, more importantly, catheter-related bloodstream infection and warrants routine use in patients at high risk of catheter-related bloodstream infection and central venous catheter or arterial catheter colonization.
