#3055 Replacement of tunneled cuffed hemodialysis catheters on coated guidewire: a strategic approach to treat CVC-related infections

Abstract Background and Aims Infections of tunneled hemodialysis central venous catheters (CVCs) are a serious problem, and the outcome of dialysis patients strongly depends on their clinical management. Several specialists are involved in choosing the appropriate technical and clinical strategy but often there is no consensus among them on the proper management. We believe that the role of nephrologists must be pivotal in this setting throughout the entire process, from the choice of vascular access to the management of complications. Here, we present our experience using an approach to replace CVCs that was conceived to minimize the rate of infections. Method We propose a CVC replacement technique to minimize the risk of contamination by using a guidewire coating that allow no contact between the old and new CVC. We carried out a retrospective observational study of tunneled CVCs replacement with this technique performed at the Nephrology Unit of the "A. Gemelli Polyclinic" between January 2020 and June 2023. The following parameters were analyzed: age, sex, infection-supporting pathogen, CVC age, and dialysis age. Results During the reporting period, we carried out a total of 87 CVC guidewire replacement procedures for HD tunneled catheters defined “access to be preserved” using our technique. Among the patients (median age 70,6) undergoing this procedure, n=5 (5.75%) presented with endocarditis (n=4 by Staphylococcus aureus, n=1 by Pseudomonas aeruginosa). The follow-up ranged from 6 months to 3 years. During this time only one patient, with endocarditis, had a recurrent infection caused by Pseudomonas aeruginosa after 3 months from the CVC replacement whereas 12 patients presented a de novo CVC infection caused by a different pathogen (n=4 by Staphylococcus aureus, n=1 by Pseudomonas Aeruginosa. Conclusion Overall, our data are encouraging as the lower rate of recurrent infections in our cohort suggests that our CVC replacement technique can be potentially used even in case of dangerous pathogens.

#2559 “Remote software technology to assist clinical decision in vascular access surveillance: single UK centre experience”

Abstract Background and Aims Optimal arteriovenous access monitoring and surveillance aims for early detection of dysfunctional access, enabling pre-emptive referral for angioplasty or surgery to prevent access loss or thrombosis. Here we compared the addition of remote software surveillance to standard clinical care in our units. Method From January–December 2023 we conducted a 12-month prospective study of maintenance hemodialysis (HD) patients. We used Vasc-Alert software technology to assist clinical decision making for vascular access (VA) surveillance in 2 out of 5 HD units. In these units, vascular access risk score was calculated using Vasc-Alert software platform from routinely collected data from the dialysis procedure as previously described [1]. Patients with high Vasc-Alert access risk score (≥7) underwent clinical assessment and were referred for fistulogram if they met the relevant KDOQI criteria [2]. The following variables were collected from all 5 HD units: baseline permanent VA prevalence, subsequent VA events (stenosis or thrombosis), access abandonment (i.e. unsalvageable access loss), complication free days (CFD)-extended over one year (defined as days without serious vascular access events, radiological or surgical intervention, VA infection, hospitalisation or use of central venous catheter). Data was collected on patients who were pre-emptively referred for diagnostic fistulogram ± angioplasty but thrombosed while awaiting intervention. Median time interval from the date of fistulogram request till the date of confirmed thrombosed access was calculated. Comparison between HD units with Vasc-Alert use (Group 1) or without (Group 2) was performed using appropriate statistical tests depending on the type and distribution of the data. Survival analysis of post-intervention primary patency rate was conducted at 3 and 6 months defined as the time from the index procedure until the next access thrombosis or reintervention [3]. Results There were 81 (53.6%) patients with permanent VA in group 1and 201 (59.3%) patients in group 2at the start of the study. We recorded 23 (28.4%) episodes of stenosis and 6 (7.4%) episodes of thrombosis in Group 1 and 40 (19.9%) episodes of stenosis and 21 (10.4%) episodes of thrombosis in Group 2 (p value 0.121 and 0.432, respectively). In Group 2, 11 patients (5.5%) developed repeated stenosis and 2 patients (1%) repeated thrombosis. In Group 1, 5 /6 (83%) cases preemptively referred for diagnostic fistulogram ± angioplasty developed thrombosis whilst awaiting elective intervention, compared with 4/21 (19%) in group 2 (p value = 0.008) (Fig. 1). The median time interval from the date of fistulogram request till date of thrombosed VA was 26 days with Interquartile range (IQR 25-75%) of 21-34 days. Group 1 had better post-intervention primary patency rate of VA (Fig. 2) and longer CFD-extended compared to group 2 (p values < 0.001 and 0.002 respectively) (Table 1). Conclusion Our study shows that integrating Vasc-Alert technology into the VA surveillance program was associated with improved early detection of high-risk access, higher primary patency rates and CFD-extended. Additionally, our data emphasizes the need to enhance interventional radiology capacity for timely access intervention, to realise the true potential of Vasc-Alert technology in prevent access thrombosis.

Effectiveness of Fistuloclysis in Nutritional Management of Enteroatmospheric Fistulas: A Retrospective Study at Santo Tomás Hospital, Panama.

Introduction Enteroatmospheric fistulas (EAF) present significant challenges in surgical management due to their complex nature and high mortality rate. Traditional approaches often rely on prolonged parenteral nutrition, but emerging evidence suggests the potential benefits of enteral nutrition via fistuloclysis, an underappreciated enteral nutrition route. This study aims to evaluate the effectiveness of nutritional therapy, specifically fistuloclysis, in patients with EAF managed at the Trauma Unit of Santo Tomás Hospital, Panama. Methods A retrospective analysis was conducted on nine male patients diagnosed with EAF between January 2016 and December 2020. Data on demographics, fistula characteristics, and nutritional management were collected through chart review. Descriptive statistics were used for analysis. Results We analyzed nine patients, all of whom received enteral nutrition (EN) via fistuloclysis in a median of 5.5 days from the diagnosis of EAF. Seven patients required parenteral nutrition (PN) at the beginning. The use of specialized enteral formulas, supplemented with hydrolyzed proteins and medium-chain triglycerides, facilitated discontinuation of PN once 80% of nutritional requirements were met via the enteral route, and EN was continued until definitive surgery. The median duration of PN was 34 days. No adverse effects related to EN were observed, whereas complications such as central venous catheter infections were reported in all cases requiring PN. Conclusion Fistuloclysis is a viable and effective alternative to traditional PN in patients with EAF. Specialized nutritional strategies, including the use of semi-elemental formulas, contribute to improved outcomes and reduced complications. Early initiation and gradual increase in enteral nutrition via fistuloclysis demonstrate safety and efficacy, underscoring the importance of tailored nutritional approaches in optimizing patient care for complex surgical conditions.

Heart failure — An unexplored risk factor for infective endocarditis after pacemaker implantation

BackgroundWith the widespread use of permanent pacemakers (PPM), and increased mortality associated with pacemaker endocarditis, it is essential to evaluate comorbidities that could potentially increase the risk of infective endocarditis (IE). Heart failure (HF), a common comorbidity, has not been well studied as an independent risk factor for development of IE in individuals with PPM. MethodsThe US National Inpatient Sample database was used to sample individuals with PPM. Patients with concomitant implantable cardioverter defibrillator, acute heart failure, history of endocarditis, intravenous drug use, prosthetic heart valves, or central venous catheter infection were excluded. Propensity matching was performed to match patients with and without HF. Pre- and post-match logistic regression was performed to assess HF as an independent risk factor for IE. A subgroup analysis was performed comparing IE rates between patients with HF with reduced (HFrEF) vs preserved (HFpEF) ejection fraction. ResultsOut of 333,571 patients with PPM included in the study, 121,862 (37 %) had HF. HF patients were older and had a higher prevalence of females. All comorbidities except for dental disease and cancer were more prevalent in the HF group. Patients with HF were 1.30 times more likely to develop IE [OR: 1.30 (1.16–1.47); p < 0.001]. The two cohorts were then matched for age, gender, and 20 comorbidities using a 1:1 propensity score matching algorithm. After matching, HF was still independently associated with increased risk of IE [OR: 1.62 (1.36–1.93); p < 0.001]. In our sub-group analysis, HFrEF and HFpEF patients had similar IE rates. ConclusionIn PPM population, HF was associated with an increased risk of IE compared to those without HF. We hypothesize that HF being a low-flow and high-inflammatory state might have contributed to this increased risk. Larger studies are required to corroborate our findings and evaluate the need for antimicrobial prophylaxis for this population.

Haematogenous Pneumonia Caused by Kocuria Kristinae in a Patient with a Central Venous Catheter.

Kocuria kristinae is a Gram-positive commensal bacterium, potentially responsible for infection.In the case of central venous catheter infection, in addition to the risk of right endocarditis, haematogenous pneumonia must also be considered.A differential diagnosis between bacterial and fungal infection is necessary (less, but to be suspected, neoplastic metastases).

Daptomycin and Ceftaroline Combination Therapy in Complicated Endovascular Infections Caused by Methicillin-Resistant Staphylococcus epidermidis.

Background In complicated endovascular infections by methicillin-resistant Staphylococcus aureus (MRSA) or Staphylococcus epidermidis (MRSE), when first-line therapy with vancomycin (VAN) or daptomycin (DAP) fails, combination therapy with ceftaroline (CFT) and DAP has been shown to be a useful approach as salvage therapy for persistent MRSA bacteremia. Objectives This study aimed to describe experience with daptomycin and ceftaroline combination therapy in MRSE-complicated endovascular infections. Methods A single-center retrospective review of consecutive patients with MRSE-complicated endovascular infections treated with ≥72 hours of DAP+CFT at any time during the course of treatment, from January 1, 2016 to December 31, 2020, at Centro Hospitalar Universitário São João (CHUSJ), Porto, Portugal, was conducted. The exclusion criteria were known resistance to daptomycin or ceftaroline, total time of combination therapy <72 hours and loss to follow-up. Results We identified seven cases that matched our criteria: five endocarditis and two central venous catheter infections. Six patients switched to combination therapy due to treatment failure with first-line agents - three due to persistent bacteremiaand three due to progression of infection despite negative blood cultures. Effective surgical source control took one to four weeks to occur. Three patients died during the treatment, one from progression of the disease and two due to another infection. Conclusions We consider the DAP+CFT combination therapy to be a valid and safe therapeutic choice in complicated patients, such as those with severe infection, poor functional status, and impossibility or delay of surgical source control. However, conclusions on the role of combination therapy should be careful due to the low number of patients and the several confounding factors.

Vascular access for hemodialysis in Italy: What a national survey reveals.

Since in Italy there are no official data on vascular access (VA) for hemodialysis the Vascular Access Project Group (VAPG) of the Italian Society of Nephrology (SIN) designed a national survey. A 35-question survey was designed and sent it to the Italian facilities through the SIN website. The basic questions were the prevalence, the location, and the surveillance of VA, the bedside use of ultrasound, the use of fluoroscopy for central venous catheter (CVC) placement, and of buttonhole technique, the role of nephrologist in the access creation. The questionnaire was completed in June 2022 by 161 facilities. The survey registered 15,499 patients, approximately one-third of the Italian dialysis population. The prevalence of arteriovenous fistula (AVF), arteriovenous Graft (AVG), and CVC were 61.8%, 3.7%, and 34.5% respectively. The AVF location was 50% in distal forearm, 20% in meanproximal forearm, 30% in upper arm. For AVF creation, nephrologists were involved in 72% of facilities while for CVC placement in 62%. As regards VA monitoring, 21% of the facilities did not have a surveillance protocol; 60% did not register AVF thrombosis and 53% did not register CVC infections. Most of facilities use the fluoroscope during CVC placement, 37% when needed, and 22% never. Ultrasound-guided puncture of complex AVFs was used by 80% of facilities. Buttonhole puncture was used in 5% of patients. Some considerations emerge from the survey data: (1) The increasing CVC prevalence compared to DOPPS 5 study. (2) The low rate of AVG prevalence. (3) The nephrologist is the operator in many VA procedures. (4) The fluoroscopy for CVC placement and the US-guide puncture of the complex AVF are widely used in most facilities. (5) The practice of the buttonhole is not widespread. (6) When the operator is the nephrologist more distal fistulas are performed.

One Fell Swoop: Septic Muscle Embolism and Central Venous Catheter Infection Imaged with [18F] Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography.

We describe the case of a 43-year-old female with hereditary hemochromatosis, previously without cardiac issues, who presented with a severe fever (>40 to 41 °C) to our hospital. Initial assessments, including transthoracic echocardiography, showed no typical signs of infective endocarditis. A contrast-enhanced CT scan revealed a hypodense area in the right subscapular muscle, alongside pleural thicknesses. Due to the critical condition, a central venous catheter (CVC) was implanted for immediate intravenous treatment. Subsequent blood cultures, positive for Staphylococcus aureus, and transesophageal echocardiography led to a diagnosis of multivalvular infective endocarditis (MIE). Subsequently, the patient underwent positron emission tomography/computed tomography (PET/CT) with [18F]Fluorodeoxyglucose ([18F]FDG), which detected increased tracer incorporation in the muscle lesion, CVC, and pleural thicknesses. The final diagnosis was CVC infection and septic embolism to the subscapular muscle in a patient with pleuritis. This case showcases the critical role of [18F]FDG PET/CT as whole-body imaging modality in diagnosing and managing complex infective cases.

Evaluation of Central Venous Catheter for Dialysis Associated with Bloodstream Infections.

Objective: Hemodialysis (HD) catheter-related bloodstream infections (CRBSIs) are a major complication of long-/short-term catheter. Material and Methods: Patients with HD CRBSIs were identified, and their blood was taken and sent to clinical pathology for culture and sensitivity testing. The inclusion criteria were adults with end-stage renal disease who required urgent HD access in the presence of a central venous catheter (CVC) infection. Results: The most common isolates among the patients with CRBSIs were gram-positive microorganisms (57.5%) and gram-negative organisms (42.5%). Overall, in our entire study, Staphylococcus aureus was the most common pathogen isolated, accounting for 30%, followed by Pseudomonas aeruginosa (20%), coagulase-negative staphylococci (CoNS) (12.5%), Klebsiella spp. and Acinetobacter (10%), Staphylococcus epidermidis (7.5%), and methicillin-resistant Staphylococcus aureus (MRSA), Escherichia coli, Staphylococcus hominis, and Enterococcus faecalis (2.5%). The commonest bacterial in femoral was S. aureus, and for subclavian was Pseudomonas aeruginosa. All S. aureus were sensitive to aminoglycosides and quinolones. P. aeruginosa was sensitive to the third generation of cephalosporins, especially cefoperazone and carbapenem. Conclusion: Nontunneled CVCs used for more than 2 weeks could increase the risk of CRBSIs. Procalcitonin and erythrocyte sedimentation rate could predict the CRBSIs in this study. This study also revealed that the gram-positive bacteria were primadonna in dialysis of CRBSIs, and most of them were sensitive to aminoglycosides.

Definition and clinical management of haemodialysis central venous catheter local infections (exit site and tunnel infection): An international consensus assessment.

To evaluate the relevance of signs and symptoms for the clinical identification of ESI and TI in HD-CVC, by means of international expert consensus, and to reach a consensus on a definition and clinical management (CM) for these infections. A recent systematic review showed a high heterogeneity in the signs/symptoms used for determining exit site infection (ESI) and tunnel infection (TI) of haemodialysis central venous catheter (HD-CVC). A modified Delphi ranking process was carried out between November 2020 and March 2021, consisting of four rounds using an online questionnaire with a panel of 26 experts from 12 countries. Experts responded on the level of relevance for the identification of ESI and TI, based on a list of 22 signs/symptoms obtained from a previous systematic review, using a 4-point Likert-type scale. After reaching consensus on the signs/symptoms, they followed the same method to reach consensus on the CM. The STROBE Checklist was used to report this study. A high degree of consensus was reached to identify the presence of ESI based on nine signs/symptoms: presence of pain at the exit site (ES) during interdialysis period, with fever ≥38°C do not suspect other cause, local signs at the ES (inflammation, induration, swelling, hyperemia/erythema ≥2 cm from ES) and obvious abscess or purulent exudate at ES; and of TI. Likewise, 5 cm were agreed upon. This Delphi study provides international expert consensus definitions of ESI and TI in HD-CVC, laying the groundwork for the validation of an HD-CVC ES clinical assessment scale for early identification of ESI. In addition, this study provides a series of attitudes to consensual clinics regarding signs/symptoms of local infections in HD-CVC, which may be useful as expert opinion in clinical practice guidelines, when there is insufficient scientific evidence.

Pantoea agglomerans: A rare infectious outbreak affecting maintenance hemodialysis patients in a tertiary care hospital.

Pantoea agglomerans is an environmental pathogen known to cause infection in immunocompromised individuals, particularly after thorn injuries. However, previous data showed few cases of human disease caused by contaminated medical products such as parenteral nutrition, anesthetic agents, blood, and peritoneal dialysis solutions. Infection in hemodialysis patients is rare. In this study, we presented a detailed account of several hemodialysis patients infected with this contagious pathogen and compared them with noninfected dialysis patients. We retrospectively reviewed the hospital records of 105 hemodialysis patients. Seventeen of 105 patients were diagnosed with P. agglomerans infection. We carefully analyzed their entire in-hospital course. Among infected patients, 52.9% were male with a median age of 49 (IQR: 32-66) years. Compared to the noninfected patients, age below 50 years, prior kidney transplantation, prior immunosuppression and antibiotics use, and dialysis via a tunneled vascular catheter were the significant epidemiological features. Despite negative microbiological investigations, we suspect the possible infectious spread via infected central venous catheter was the likely infectious source. Most importantly, all patients responded well to intravenous antibiotics. Only two patients required the removal of the tunneled catheter. Their mortality rate was 0%. P. agglomerans infection, although considered rare, is becoming increasingly prevalent among dialysis patients. Its occurrence must be appraised as an infectious outbreak rather than mere contamination. Prompt treatment, source identification, and early implementation of preventive strategies should always be the goal to curtail this infection at an early stage.

Ethanol Lock for Prevention of CVC-Related Bloodstream Infection in Pediatric Patients: A Systematic Review and Meta-Analysis.

Ethanol lock therapy (ELT) can be used in patients with an indwelling central line to assist in the prevention of central venous catheter (CVC)-associated infections. However, its efficacy has not been consistently demonstrated in the pediatric population. The primary objective of this review and meta-analysis was to determine the efficacy and safety of ELT in prevention of central line-associated bloodstream infection (CLABSI) in the pediatric population. A search was conducted with the PubMed, CINAHL, PSCYInfo, Cochrane Library, and Academic Search Premier databases from inception through January 21, 2022. Studies were included if they reported incidence of CVC-related infections with ELT in pediatric patients. Meta-analyses used random-effects models according to the heterogeneity of all included studies. Of 736 studies, 25 met inclusion criteria for review and 10 for inclusion in the meta-analysis. Meta-analysis with pre- and post-ELT treatment showed that use of ELT significantly decreased mean CVC-related infections when compared with pre-treatment with no ELT with a mean difference of -5.79 (95% CI, -9.08 to -2.51; p < 0.001). The number of CVC infections also significantly decreased (OR, 0.42; 95% CI, 0.23-0.75; p = 0.004). Increased risk of thrombosis and increased frequency of catheter breakage, repair, and replacement were noted in several studies. Ethanol lock therapy is effective in preventing infection related to central venous catheter use in pediatric patients. Further study is warranted to determine the optimal protocol for, and incidence of, adverse events related to use of ELT.

Etiological analysis of infection after CRS + HIPEC in patients with PMP

BackgroundCytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) is the standard treatment for pseudomyxoma peritonei (PMP). It can significantly prolong the survival of patients, but at the same time may increase the risk of postoperative infection.MethodPatients with PMP who underwent CRS + HIPEC at our center were retrospectively analyzed. According to PMP patients, basic clinical data and relevant information of postoperative infection, we analyzed the common sites of postoperative infection, results of microbial culture and the antibiotics sensitivity. Univariate and multivariate analysis were performed to explore infection-related risk factors.ResultAmong the 482 patients with PMP, 82 (17.0%) patients were infected after CRS + HIPEC. The most common postoperative infection was central venous catheter (CVC) infection (8.1%), followed by abdominal-pelvic infection (5.2%). There were 29 kinds of microbes isolated from the culture (the most common was Staphylococcus epidermidis), including 13 kinds of Gram-positive bacteria, 12 kinds of Gram-negative bacteria, and 4 kinds of funguses. All the antibiotics sensitivity results showed that the most sensitive antibiotics were vancomycin to Gram-positive bacteria (98.4%), levofloxacin to Gram-negative bacteria (68.5%), and fluconazole to fungus (83.3%). Univariate and multivariate analysis revealed the infection independent risk factors as follow: intraoperative blood loss ≥ 350 mL (P = 0.019), ascites volume ≥ 300 mL (P = 0.008).ConclusionPMP patients may have increased infection risk after CRS + HIPEC, especially CVC, abdominal-pelvic and pulmonary infections. The microbial spectrum and antibiotics sensitivity results could help clinicians to take prompt prophylactic and therapeutic approaches against postoperative infection for PMP patients.

Dialysis Central Venous Catheter–Associated Sepsis: Complimentary Role of Local Susceptibility Pattern

Introduction: Effective treatment of central venous catheters infections could be very challenging, and may require catheter removal. Reinsertion could worsen the economic burden on patient, particularly those paying out of pocket.&#x0D; Methods: Management was anchored on dialysis-based nitrogenous waste, antigen and cytokines clearance, in addition to antibiotic treatment that was based on sensitivity results and, local microbial susceptibility pattern, to minimize cost.&#x0D; Results: He was febrile (38.40C), had a non-tunnelled jugular vein catheter with a dirty, wet dressing with a greenish tinge. He had tachycardia (110/min), fine crepitaions in the lung bases and ascites. Blood and central line samples grew Pseudomonas aeuriginosa sensitive to Imipenem ++ (both), Vancomycin + (blood) and Ciprofloxacin + (central line). He had 4 haemodialysis sessions through the infected catheter, a dose of Vancomycin but none of Imipenem (on account of cost). He had a full course of intravenous Ciprofloxacin and Ceftazidime which was introduced on the basis of local microbial susceptibility pattern as it had been very effective in managing infective conditions in our CKD patients (either in mono or in combination therapy), particularly in patients unable to afford culture and sensitivity test . He had a good clinical and, microbiological recovery as a repeat culture after seven days of antibiotics treatment showed no growth. The catheter was retained for use in further dialysis sessions.&#x0D; Conclusion: Treatment of infected non-tunnelled dialysis catheters could be very challenging particularly in resource poor settings. The use of low cost antibiotics with positive local microbial susceptibility pattern could be very beneficial, additive and effective in treatment and in minimizing complications.

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

Central line-associated bloodstream infections (CLABSI) are the most common healthcare-associated infection in children. Antimicrobial lock therapy (ALT) is a recommended component of CLABSI treatment; however, studies characterizing pediatric ALT-based CLABSI therapy are few. All CLABSI treated with ALT at a single tertiary-care pediatric hospital for years 2004-2018 were identified by retrospective chart review and demographic, clinical, microbiological and pharmacy data were extracted. Three clinical outcomes were defined: CLABSI clearance, central venous catheter (CVC) removal and infection recurrence. Factors associated with these outcomes were examined and patterns in pathogen occurrence were described. During the study period, 1188 CLABSI treated with ALT were identified. In all, 969 (85%) CLABSI initially cleared. In the CLABSI with initial clearance, CVCs were retained a median of 63 days after infection onset, and 20% recurred. Skin-colonizing microbes ( Staphylococcus aureus , coagulase-negative Staphylococci) were more likely to produce monomicrobial infections, whereas bowel-colonizing microbes ( Escherichia coli , Enterococci) were more associated with polymicrobial infections. In a multivariate model, infection history, resistant pathogens and CVC type were strongly correlated with infection recurrence, whereas bone marrow transplant status, neutrophil count and line type were correlated with CVC removal. Optimal therapeutic approaches to pediatric CLABSI remain uncertain, including the utility of ALT. Prior reports of ALT use in children have been smaller in size and largely described hematology-oncology or hemodialysis populations. We describe trends in pediatric CLABSI, including efficacy among solid organ transplant recipients and children with short-gut syndrome. These data provide guidance on selecting CLABSI for optimal ALT use.

Central Venous Catheter–Associated Infection: An Experience of a High Complexity Hospital

Abstract Background Central line–associated bloodstream infections (CLABSIs) are among the pathologies that increase mortality and morbidity in hospitalized patients with some type of device. Objective The aim of this study was to describe the clinical, microbiological, therapeutic characteristics, and economic costs associated with CLABSI. Methodology This study is a retrospective cohort study in subjects hospitalized at the Central Military Hospital of Bogotá, Colombia, describing the clinical, microbiological, and therapeutic characteristics in patients undergoing the insertion of a central venous catheter (CVC) and comparing them between subjects who did or did not develop infection. Central line–associated bloodstream infections were defined based on the criteria of the Infectious Diseases Society of America, a significant P &lt; 0.05 was considered. Results A total of 821 patients were evaluated, of which 75 had a diagnosis of CLABSI, reaching a frequency of 9.1%. Patients with CVC infection were 12 years younger on average compared with the control group (55 vs 67 years; P = 0.001), 85.3% of the population with CVC-associated infection were men compared with 62.0% (P = 0.023) of the group without CLABSI. The CVC anatomical insertion sites with the highest proportion in both study groups were at the jugular and right subclavian levels (P = 0.001). The overall mortality of the study population was 24.6%, reaching 32% in the population with CLABSI compared with 23.9% in the control group (P = 0.254). Patients with CLABSI present higher associated costs during hospitalization (P = 0.013) and total costs (P = 0.028). Conclusions The younger population, the male sex, and the anatomical insertion of the CVC at the jugular and right subclavian levels presented a higher proportion of CLABSI. The costs associated with hospitalization and total costs were higher in the group of patients with CLABSI.

Compliance with central venous catheter infection prevention practices after intervention with simulation

RESUMO Objetivos: avaliar o efeito de uma intervenção educativa pautada em simulação clínica na adesão de profissionais de enfermagem às práticas de prevenção de infecções primárias de corrente sanguínea associadas ao cateter venoso central de inserção periférica em Unidade de Terapia Intensiva Neonatal. Métodos: estudo quase-experimental, com avaliação pré e pós-intervenção com um grupo único. A população foi de 41 profissionais de enfermagem, sendo realizadas 31 observações antes e após intervenção. As análises foram por meio de estatística descritiva e pelo Teste Não Paramétrico de McNemar. Adotou-se um nível de significância de 5%. Resultados: após a intervenção, houve aumento da adesão às práticas de prevenção de antissepsia cirúrgica e higiene das mãos do profissional, antissepsia da pele com clorexidina, espera do tempo do efeito da clorexidina alcoólica e cumprimento da técnica estéril. Conclusões: a intervenção educativa mostrou efeito no aumento da adesão às práticas de prevenção da infecção associadas ao cateter.
