Sex-disaggregated analysis of central venous catheter-related bloodstream infections in patients with cancer.

Men are generally more susceptible to bacterial infections than women. Central venous catheters (CVCs), often used to administer systemic treatment in patients with cancer, are an important source of infection. However, little is known about sex-specific differences of CVC-related bloodstream infections (CRBSIs) in patients with cancer. This study aimed to compare CRBSIs in men vs. women in a large cohort of patients with cancer. Data were derived from the SECRECY registry including non-selected patients with centrally inserted non-tunneled internal jugular or subclavian vein CVCs in 10 hematology and oncology sites in Germany. Only CRBSIs classified as definite CRBSI (dCRBSI) or probable CRBSI were included, and the combination of both was summarized as dpCRBSI. CVCs were matched 1:1 for underlying disease, anatomic site of CVC insertion, type of CVC dressing, antimicrobial coated CVC, complicated CVC insertion and CVC in situ time by propensity score matching (PSM). Endpoints were CRBSI rates and incidences in CVCs inserted in men vs. women. A total of 5075 CVCs registered from March 2013 to March 2024 were included in the analysis, of which 3024 comprises the PSM cohort. 1512 (50.0%) CVCs were inserted in men. Underlying diseases mainly were hematological malignancies (96.4%). While there was no statistically significant difference between men and women in the dCRBSI rate (5.4% vs. 4.1%; p=0.12) and the dCRBSI incidence (3.8 vs. 2.9/1000 CVC days; p=0.11), the rate of dpCRBSI (9.9% vs. 6.7%; p=0.002) and the dpCRBSI incidence (7.0 vs. 4.7/1000 CVC days; p=0.002) were significantly higher in men vs. women. The proportion of coagulase-negative staphylococci as causative agent of both dCRBSI and dpCRBSI was higher in men than in women (58.8% vs. 41.2%; p=0.07, and 61.5% vs. 38.5%; p=0.002, respectively). A multivariable regression revealed neutropenia as an independent risk factor for dCRBSI and male sex as risk factor for dCRBSI and dpCRBSI. In patients with hematological malignancies, men have a higher risk of CRBSI than women. This finding may be attributed to the high number of jugular vein inserted CVCs which in men may be associated with higher rates of skin colonization than in women. Special preventive measures such as earlier removal of CVCs in men may be studied in future.

Clinical outcomes and the impact of treatment modalities in children with carbapenem-resistant Enterobacteriaceae bloodstream infections: a retrospective cohort study from a tertiary university hospital.

The increasing prevalence of carbapenem-resistant Enterobacteriaceae (CRE) infections among children represents a significant global concern, leading to elevated mortality rates. The aim of this study was to evaluate the risk factors, outcomes, 30-day mortality rates and contributing factors in children with CRE bloodstream infections (CRE-BSIs). Data regarding demographic characteristics, treatment approaches and outcomes of hospitalized children aged 0-18 years diagnosed with CRE-BSIs between January 2018 and December 2022 were extracted from medical records. Mortality within 30 days of diagnosis and the predictive factors were analysed. A total of 114 children, with a median age of 11 months (range: 6-69.5), were included. All cases of CRE-BSIs were either healthcare associated or hospital acquired and presented with at least one underlying comorbidity. A previous history of CRE colonization or infection rate was 48.2% (55/114). Klebsiella pneumoniae 87.7% (100/114) was the most frequently isolated microorganism, with a 30-day mortality rate of 14% (16/114). Multivariate analysis identified paediatric intensive care unit admission, invasive mechanical ventilation, inotropic support and thrombocytopenia due to CRE-BSIs as the most discriminative predictors for 30-day mortality (P < 0.001). Central venous catheter (CVC) removal was associated with a reduced mortality rate (P = 0.012). High-dose prolonged infusion of MEM-based or polymyxin-based antibiotic combinations did not impact survival. Lower MEM MIC values were associated with improved survival. The mortality rate of CRE-BSI is notably high in childhood. The use of antibiotic combination strategies did not demonstrate a significant impact on 30-day survival; however, the removal of CVCs was found to lower mortality rates.

Knowledge and Practices Regarding Prevention of Central Venous Catheter Removal-Associated Air Embolism: A Survey of Nonintensive Care Unit Medical and Nursing Staff.

Air embolism is a potentially serious complication of central venous catheter (CVC) use. While CVC insertion is usually performed by a trained specialist, extraction is frequently the responsibility of junior staff members. This complication can be easily prevented by following several simple measures described in common guidelines. We conducted a single-center survey to assess knowledge and practices concerning the prevention of air embolism associated with CVC removal among healthcare workers from nonintensive care units. The correct answers to the questionnaire were determined according to best-practice recommendations for CVC removal. Based on a comparison of the total sum of correct answers between the categories of groups, factors that predicted the level of knowledge were identified using an independent sample t test. Of the 156 respondents, one-third were unfamiliar with air embolism as a complication of CVC extraction. Almost 80% were unaware of the existence of a CVC removal protocol. Almost half of respondents did not follow guidelines regarding patient position when removing a CVC, 72% did not ask the patient to perform the Valsalva maneuver during the procedure, and 54% did not ask the patient to remain supine after the procedure. Adherence to the protocol was correlated with professional experience, with a lower level among those with experience of less than 1 year and, particularly, among interns. Our survey revealed inappropriately low awareness of CVC removal-associated air embolism risk and low familiarity with CVC removal best-practice recommendations among nonintensive care unit healthcare workers. Staff members with experience of less than 1 year, including interns, were found to have a lower level of knowledge. These findings emphasize the importance of development and distribution an internal hospital protocol and the integration of educational intervention into a preliminary internship program.

Central Venous Catheter-associated Venous Thromboembolism in Children: A Prospective Observational Study.

Our objective was to study the proportion of children developing Catheter-related thrombosis (CRT) following central venous Catheter (CVC) insertion and the risk factors of CRT in pediatric patients with CVC. One hundred four children aged 29 days to 18 years who had a percutaneous non-tunneled CVC inserted were enrolled. Ultrasonogram (USG) with venous Doppler scan was performed within 48 hours of CVC removal to diagnose CRT. The major indications for CVC insertion were surgical care 34 (32.6%) and ICU care 28(26.9%). The median age of the patients was 3 years, and 75% were males. The median number of CVC days was 10 (IQR 5.15). CRT was seen in 45(43.3%), of which 33 (73.3%) were asymptomatic. The rate of CRT was 35.69 cases per 1000 CVC days (95% CI 26.03-47.75). The number of days a catheter was in place and USG-guided catheter insertion was a significant risk factor. The multivariate logistic regression model showed that the duration of CVC in situ was independently associated with the development of CRT (OR, 1.06; 95% CI 1.0-1.1; P =0.02). CVC duration was a major risk factor for the development of CRT. There was a higher risk of developing a symptomatic CRT with central venous catheters than hemodialysis sheaths.

Impact of clinically unsuspected venous thrombotic events on CVC removal and survival in pediatric cancer patients: A population-based study from the Maritimes, Canada.

Venous thromboembolism (VTE) is a well-recognized complication in pediatric cancer patients. We aimed to determine the frequency of central venous catheter (CVC) removal and survival impact of children with cancer who develop VTE. After ethics approval, a retrospective population-based study of cancer patients less than 21 years between 2005 and 2020, in the Maritime Provinces Nova Scotia, New Brunswick, and Prince Edward Island was conducted. Clinical data was collected from hospital charts and online medical records. Data on demographics, cancer diagnosis and treatment, diagnosis of VTE, use of CVC, were assessed. Kaplan-Meier survival curves were computed and compared among study groups. This study included 770 patients with a male to female ratio of 1.1:1. There were 49 patients with symptomatic VTE, 49 patients with clinically unsuspected VTE, and 671 patients with no VTE. There were 15 (1.9%) non-CVC-symptomatic (ncsVTE), 34 (4.4%) CVC-symptomatic (csVTE), 40 (5.2%) non-CVC-clinically unsuspected (ncuVTE), 9 (1.2%) CVC-clinically unsuspected (cVTE), and 671 (87%) no VTE patients. The mean number of CVCs required during treatment was significantly higher among patients with VTE (p < 0.001). Both symptomatic and clinically unsuspected VTE required significantly more CVCs compared to no VTE patients (p < 0.001 and p = 0.049 respectively). Kaplan-Meier survival curves showed ncsVTE patients' survival was significantly reduced compared to all other patients (p < 0.001). This study demonstrates that pediatric oncology patients with ncsVTE have significantly lower survival. This suggests that ncsVTE may be a biomarker for increased disease burden. This study also demonstrated that clinically unsuspected VTE had significantly more CVCs placed during treatment compared to patients without a VTE, indicating the need for better screening.

The Mechanics, Art, and Value of Central Line Stewardship

Background: Central venous catheter (CVC) utilization and central-line associated bloodstream infection (CLABSI) have increased nationwide. Busy providers can easily overlook the recommended practice of daily assessment of the ongoing indication for CVC. Prospective audit and feedback (PAF) is widely used and the gold standard for antibiotic stewardship programs (ASP), but reports involving PAF for device use are scarce. Therefore, we decided to evaluate the usefulness and feasibility of PAF for reducing device utilization and ultimately CLABSI rates at our 528-bed tertiary care hospital. Methods: A PAF-based Central Line Stewardship (CLS) initiative was launched in February 2023, with a team of hospitalists, infectious diseases physicians, health informatics, vascular access nurses, and infection preventionists. On business days, CVC line-lists were exported from the electronic medical record (EMR), into a REDCap (Research Electronic Data Capture) database for team members to evaluate, in real-time, all non-ICU CVCs in place for more &gt;72 hours (Figures 1 and 2). For CVCs eligible for stewardship, CLS members placed Legal-approved note into the patient’s EMR, advising CVC removal or alternative IV access (Figure 3). CVCs continued to be audited until removal or patient discharge. Recommendation outcomes were tracked over the subsequent 72 hours for acceptance. Standardized Utilization Rates (SUR) and Infection Rates (SIR) were calculated and compared using the National Healthcare Safety Network. Results: Between February and August 2023, the CLS team reviewed 861 CVCs, representing 581 unique patient encounters, and made 622 recommendations. Recommendations to remove or replace the CVC represented 23.5% (146) of reviews, and 57% of these CVCs were removed within 3 days. 95% of removed lines had no adverse outcomes and did not require reinsertion. Hospital-wide CVC utilization decreased 18.7% from a SUR of 1.006 in the previous year, to 0.818 during the 7-month pilot period (p &lt; 0 .001). In the 4 months following the pilot period, decreased CVC utilization was sustained with an SUR of 0.797. Non-ICU CLABSI SIR decreased from 1.282 in 2022 to 1.024 in 2023 (p=0.36). Average time physician required for CLS review approximated a 0.4 full-time equivalent a week. The intervention was well received, with requests for expansion to urinary catheters. Conclusion: CLS safely and significantly reduced device-utilization; directly via documentation and recommendation, and indirectly through increased awareness and the Hawthorne Effect. Examples of the “art” of CLS include when to leave a discoverable note and how to determine ongoing need for CVC in a fragile patient.

Expert consensus on safety management of vascular access devices for patients with digestive system cancer (2024)

The rational selection and standardized management of vascular access devices is an urgent issue in the treatment of digestive system cancer. The purpose of this consensus is to develop solutions for the safe management of intravenous vascular access devices for patients with digestive system cancer and to provide evidence for clinical decision-making. This consensus is developed by a group of experts from multiple-disciplines in China International Exchange and Promotive Association for Medical and Health Care Clinical Nutrition Health Branch, Clinical Nutrition Branch of Chinese Nutrition Society, Chinese Society for Parenteral and Enteral Nutrition. It is based on the best current evidence and combined with Chinese clinical practice experience. The recommendations were discussed and on the following topics: how to choose vascular access devices for patients with digestive system cancer; optimal selection of puncture sites and positioning of the tip for peripherally inserted central catheters; prevention and management of complications post-central venous catheterization; strategies for prevention and treatment of central venous catheter occlusion; criteria for central venous catheter removal; indications for the use of venous port access and criteria for peripheral venous catheter in patients with digestive system cancer.

A lower fibrinogen threshold does not lead to increased bleeding risk in patients receiving therapeutic plasma exchange: A prospective single-center analysis.

Plasma exchange (PLEX) therapy is indicated for several disorders. The 5% albumin is often used as a sole replacement fluid during most PLEX. However, each 1.0 plasma volume exchange depletes coagulation factors by ~65%. Although most coagulation factors recover to hemostatic levels within 24 h post-PLEX, fibrinogen requires 48-72 h to recover. Fibrinogen is the key coagulation protein for hemostasis. Therefore, fibrinogen is often monitored during the acute course of PLEX, and plasma is supplemented to prevent bleeding if fibrinogen is <100 mg/dL. We conducted a prospective, single-center, observational study to evaluate bleeding risk in adults who received an acute course of PLEX with a fibrinogen level of 80-100 mg/dL without plasma supplementation during the procedure or before central venous catheter removal. The study group was compared to patients with plasma fibrinogen >100 mg/dL. Among the 275 patients who received 1406 PLEXes, 62 patients (23%) who underwent 323 PLEXes met the inclusion criteria, and only 2 (3%) patients had bleeding while on oral anticoagulants. In contrast, out of 275 patients, 143 (52%) with fibrinogen levels >100 mg/dL received 751 PLEX treatments, and bleeding occurred in 2 (1%) while on low-molecular-weight heparin. Our findings suggest that a pre-procedure fibrinogen threshold of 80-100 mg/dL without plasma supplementation does not increase bleeding risk unless patients were on anticoagulation.

Guideline Adherence and Outcomes of Patients with Candidemia in Brazil.

Candidemia is a significant cause of mortality among hospitalized patients, both worldwide and in Brazil. Prompt and appropriate treatment are essential to mitigate mortality, and clinical practice guidelines aim to optimize patient care based on the best scientific evidence. This study aims to examine the management of candidemia, assessing adherence to the guidelines of the Brazilian Society of Infectious Diseases in a single center located at São Paulo, Brazil. All adult patients hospitalized from 2016 to 2018 who presented one positive blood culture for Candida spp. were included. Electronic medical records were retrospectively reviewed to collect information relevant to the treatment for candidemia, in order to assess the adherence to the Brazilian guideline for the management of candidemia in relation to nine defined outcomes, and we correlated those findings with 30-day mortality by using uni- and multivariate analyses. A total of 115 patients were included; 68 patients (59.1%) were male, with a mean age of 55 years. C. albicans, C. tropicalis and C. glabrata were the most prevalent species. In total, 80 patients (69.5%) received antifungal treatment. The adherence to Brazilian guideline recommendations was determined as described in the following: initial treatment with echinocandin in 48 (60%); step-down to fluconazole in 21 (26.2%); collection of first control blood culture in 43 (58.9%); collection of second control blood culture, if the first one had been positive, in 14 (73.6%); treatment for 14 days after the first negative blood culture in 53 (65.4%); central venous catheter (CVC) removal in 66 (82.5%); CVC removal if the first control blood culture had been positive in 17 (89.4%); performance of a transthoracic echocardiogram in 51 (63.7%) and performance of a fundoscopy in 59 (73.7%). Univariate analysis showed that CVC removal and initial echinocandin therapy were more prevalent in the surviving group, but with no statistically significant difference. On the other hand, step-down to fluconazole demonstrated higher survival rate in the multivariate analysis OR 0.15 (95% CI 0.03-0.8); p = 0.02. The analysis of these nine recommendations demonstrates that it is necessary to improve adherence to specific recommendations and also disseminate strategies of the initial use of echinocandin as the drug of choice and addressing length of treatment and follow-up and complementary exams. Our study provides reassurance that the step-down to fluconazole is safe and may be recommended, if the preexisting conditions are present.

Superior Vena Cava Thrombosis in A Young Hemodialysis Patient After 1 year of Central Venous Catheter Removal: A Case Report

Introduction:&#x0D; Superior vena cava (SVC) syndrome is a rare but serious condition resulting from obstruction of the superior vena cava or its tributaries. Although often associated with malignancy, it can also occur due to central venous catheterization(1). Acute SVC syndrome following catheter removal is uncommon. &#x0D; Case Report: &#x0D; We present a 35-year-old hemodialysis patient with a history of central venous catheterization for hemodialysis one year prior. During a routine hemodialysis session, the patient developed symptoms of shortness of breath, neck swelling, and cyanosis of the lips. Physical examination revealed neck edema and prominent superficial vascular bifurcations. Without imaging studies, it was confused with cellulitis, but CT angiography later confirmed SVC thrombosis. The patient was started on anticoagulation and transferred to a tertiary hospital for further management. &#x0D; Conclusion: &#x0D; Emergency physicians should be aware of SVC syndrome, especially in hemodialysis patients with a history of central venous catheterization. Although it is often associated with malignancy, this case highlights the importance of considering SVC thrombosis even after catheter removal. Prompt diagnosis and appropriate management are essential to prevent life-threatening complications. Therefore, recognition and inclusion of SVC syndrome in the differential diagnosis is essential for timely intervention and improved patient outcomes.

Invasive candidiasis.

Invasive candidiasis is an important fungal disease caused by Candida albicans and, increasingly, non-albicans Candida pathogens. Invasive Candida infections originate most frequently from endogenous human reservoirs and are triggered by impaired host defences. Signs and symptoms of invasive candidiasis are non-specific; candidaemia is the most diagnosed manifestation, with disseminated candidiasis affecting single or multiple organs. Diagnosis poses many challenges, and conventional culture techniques are frequently supplemented by non-culture-based assays. The attributable mortality from candidaemia and disseminated infections is ~30%. Fluconazole resistance is a concern for Nakaseomyces glabratus, Candida parapsilosis, and Candida auris and less so in Candida tropicalis infection; acquired echinocandin resistance remains uncommon. The epidemiology of invasive candidiasis varies in different geographical areas and within various patient populations. Risk factors include intensive care unit stay, central venous catheter use, broad-spectrum antibiotics use, abdominal surgery and immune suppression. Early antifungal treatment and central venous catheter removal form the cornerstones to decrease mortality. The landscape of novel therapeutics is growing; however, the application of new drugs requires careful selection of eligible patients as the spectrum of activity is limited to a few fungal species. Unanswered questions and knowledge gaps define future research priorities and a personalized approach to diagnosis and treatment of invasive candidiasis is of paramount importance.

Characterizing Patients Presenting on Hospital Admission With Central Line-Associated Bloodstream Infections: A Multicenter Study.

There are no systematic measures of central line-associated bloodstream infections (CLABSIs) in patients maintaining central venous catheters (CVCs) outside acute care hospitals. To clarify the burden of CLABSIs in these patients, we characterized patients with CLABSI present on hospital admission (POA). Retrospective cross-sectional analysis of patients with CLABSI-POA in 3 health systems covering 11 hospitals across Maryland, Washington DC, and Missouri from November 2020 to October 2021. CLABSI-POA was defined using an adaptation of the acute care CLABSI definition. Patient demographics, clinical characteristics, and outcomes were collected via record review. Cox proportional hazard analysis was used to assess factors associated with the all-cause mortality rate within 30 days. A total of 461 patients were identified as having CLABSI-POA. CVCs were most commonly maintained in home infusion therapy (32.8%) or oncology clinics (31.2%). Enterobacterales were the most common etiologic agent (29.2%). Recurrent CLABSIs occurred in a quarter of patients (25%). Eleven percent of patients died during the hospital admission. Among patients with CLABSI-POA, mortality risk increased with age (hazard ratio vs age <20 years by age group: 20-44 years, 11.2 [95% confidence interval, 1.46-86.22]; 45-64 years, 20.88 [2.84-153.58]; ≥65 years, 22.50 [2.98-169.93]) and lack of insurance (2.46 [1.08-5.59]), and it decreased with CVC removal (0.57 [.39-.84]). CLABSI-POA is associated with significant in-hospital mortality risk. Surveillance is required to understand the burden of CLABSI in the community to identify targets for CLABSI prevention initiatives outside acute care settings.

Staphylococcus capitis Central-Line-Associated Bloodstream Infections in the Neonatal Intensive Care Unit: A Single-Center, Four-Year Experience in Central-Line Management during Sepsis Treatment.

Coagulase-negative staphylococci (CoNS) are reportedly responsible for 50-60% of bloodstream infections in very preterm (<1500 g) infants in neonatal intensive care units (NICUs). Staphylococcus capitis is an increasingly prevalent pathogen in the neonatal setting, frequently causing central-line-associated bloodstream infections (CLABSIs) that can be difficult to eradicate. Central venous catheter (CVC) removal versus in situ treatment with CoNS CLABSIs is a controversial treatment strategy with no clear consensus. We reviewed all S. capitis CLABSIs in our NICU between 2019 and 2022, focusing on the role of catheter removal in eradication. Among the 25 patients, 17 CVCs were removed after diagnosis, leading to a 76.5% eradication rate in this group. Three infants had a persistently positive blood culture after CVC substitution. A new catheter was then inserted after a 48 h washout period, resulting in resolution of the infection. Only two of the eight patients (25%) who retained their catheter after diagnosis achieved infection eradication with antibiotic therapy alone. When feasible, catheter removal seems to be the most effective strategy for eradicating S. capitis CLABSIs, sometimes even requiring a 48 h washout period before reinsertion. Further studies on this topic are needed to better standardize the management of this type of infection.

Antibiotic use at planned central line removal in reducing neonatal post-catheter removal sepsis: a systematic review and meta-analysis.

Post-catheter removal sepsis (PCRS) is a notable complication of indwelling central venous catheters (CVCs) in neonates, which is postulated to be secondary to the disruption of biofilms formed along catheter tips up on CVCs removal. It remains controversial whether this could be prevented by antibiotic use upon CVCs removal. We aimed to evaluate the protective effect of antibiotic administration at the time of CVCs removal. We searched through PubMed, EMBASE, Cochrane databases and reference lists of review articles for studies comparing the use of antibiotics versus no use within 12 h of CVCs removal. Risk of bias was assessed using the modified Newcastle-Ottawa Scale and Cochrane risk-of-bias tool accordingly. Results of quantitative analyses were presented as mean differences (MD) or odds ratio (OR). Subgroup and univariate meta-regression analyses were performed to identify heterogeneity. The review included 470 CVCs in the antibiotic group and 658 in the control group. Antibiotic use within 12 h of CVCs removal did not significantly reduce the incidence of PCRS (OR = 0.35, 95% CI: 0.08-1.53), but was associated with a lower incidence of post-catheter removal blood stream infection (OR = 0.31, 95% CI: 0.11-0.86). Dosage of vancomycin and world region were major sources of heterogeneity. Antibiotic administration upon CVCs removal does not significantly reduce the incidence of PCRS but offers less post-catheter removal blood stream infection. Whether this will be converted to better clinical outcomes lacks evidential support. Further randomized controlled studies with longer follow-up are needed. Results of our meta-analysis suggest that antibiotic use at planned central line removal removal does not significantly reduce the incidence of PCRS but offers less blood stream infection, which might contribute to future management of central lines in neonates. https://www.crd.york.ac.uk/, PROSPERO (CRD42022359677).

Removal of stuck tunnelled dialysis line requiring cardiopulmonary bypass and venous repair.

Tunnelled central venous dialysis catheters can usually be removed easily. However, their removal can become rarely complicated requiring more invasive techniques. We report a case in which cardiopulmonary bypass and repair of great veins was required for safe removal. A 38-year-old female with end-stage renal failure and a 3-year-old Hickman line inserted into her right internal jugular vein was referred to our cardiac surgical unit following failed attempts of line removal by local vascular surgical team using open vascular surgical techniques. As a result, an MDT decision was made that it was safer to proceed to a cardiothoracic surgical approach rather than other techniques. Investigations showed significant calcification surrounding the line which was adherent to the venous wall. Removal of the retained catheter required median sternotomy and the use of cardiopulmonary bypass as the great veins had to be opened to free the line and allow complete removal. The line was successfully removed with its encircling calcified sheath, and the veins were closed primarily without needing a patch repair. The integrity of the great veins was maintained to meet the on-going need this young patient has for central venous access. The patient made an uneventful recovery. When other measures fail, sternotomy and cardiopulmonary bypass provide a safe option for complete removal of stuck central venous catheters with low risk to the patient.

AHP P06 Optimizing Coagulation Screen Practices in CVC Removal Amongst Surgical Patients: A Retrospective Audit Assessing Necessity, Compliance, and Implications

Abstract Background Conflicting findings in recent literature question the significance of traditional coagulation variables in predicting bleeding associated with central venous catheter (CVC) removal. This audit evaluates the necessity and compliance of conducting same-day coagulation screens at Churchill Hospital. The study assesses the practice's relevance, compliance rates, and associated costs, offering implications for clinical decision-making, resource utilization, and potential modifications to current practices. The findings may lead to the adoption of new predictive factors or a targeted approach to coagulation testing, optimizing patient care and resource allocation in CVC removals. Methods This retrospective audit focused on surgical patients in the upper gastrointestinal, hepatobiliary and pancreatic, lower gastrointestinal, and transplant surgery departments at the Churchill Hospital. The study encompassed all instances of central venous catheter (CVC) removal that occurred between January 1st, 2022, and December 31st, 2022. Data retrieval was conducted using electronic patient records, and coagulation test results were interpreted utilizing the reference ranges available in the electronic patient record system (INR 0.9-1.2, PT 9-12, APTT 20-30). Results 78 patients had an average age of 53 years and a mean hospital stay of 35 days. The average duration of CVC in-situ was 8.9 days. Patients underwent an average of 5.07 coagulation tests per stay, equivalent to 0.28 tests per admission day. Among the audited patients (n=67), 41.8% had same-day coagulation screens, 17.9% had the screen one day prior to CVC removal, and 40.3% had the screen more than one day before removal. Analysis showed that 88% had normal INR values, with only eight patients having abnormal values. Furthermore, 74.6% and 58.2% had normal PT and APTT values, respectively. Conclusions This retrospective audit of CVC removals in surgical patients at Churchill Hospital revealed a concerning in-compliance rate of 44% with coagulation screens during CVC removals. Most patients had normal coagulation parameters, questioning the need for same-day screens. Delays and high costs (£64.76 per patient, £12.95 per screen) were incurred. Individualized risk-based approach, considering bleeding history, could be more efficient. Implementing targeted coagulation testing saves costs and optimizes resource utilization. Further evaluation required to improve patient care and resource allocation in CVC removals, reducing reliance on routine same-day screens.

Use of 2% taurolidine lock solution for treatment and prevention of catheter-related bloodstream infections in neonates: a feasibility study

Taurolidine lock, a technique used to prevent or treat catheter-related bloodstream infection (CRBSI), is effective in adult and paediatric patients but has been described rarely in neonates. The aim of this descriptive retrospective study, was to determine the feasibility and direct outcomes of prophylactic and therapeutic taurolidine locks in term and preterm neonates. We implemented the use of therapeutic taurolidine lock in addition to antibiotic treatment with the aim of catheter salvage in critical neonates with difficult vascular access (group 1). In addition, we introduced taurolidine lock as a preventive measure in neonates with a central venous catheter (CVC) at high risk of developing CRBSI (group 2). Every 24h (in the treatment group) a 2% taurolidine solution was injected and the catheter locked for at least 120min, until infection clearance (group 1). In the preventive group, the catheter was locked for 30min every 48h until CVC removal (group 2). Thirty-seven neonates who received taurolidine were included in this study. We did not observe any major adverse events. In group 1 (21 cases), clinical symptom disappearance and bacteraemia clearance were achieved without catheter removal in 18 cases (85.7%); in the other three neonates the catheter was removed shortly after the start of the locks as it was possible to replace the CVC. In group 2 (16 neonates), no CRBSI was observed during the duration of the catheter placement. In this retrospective study, taurolidine was successfully used in neonates both for prevention and treatment of CRBSI, without major undesired effects. A larger cohort and a randomized clinical trial is warranted in order to establish its efficacy and safety in neonates.

Early Central Venous Catheter Replacement After Candida in Pediatric Intestinal Failure Patients.

Deferred central venous catheter (CVC) replacement places children with intestinal failure (IF) at risk of complications. We hypothesized that early CVC replacement after uncomplicated candidemia is safe and beneficial. We performed a retrospective review of children with IF. Patients were divided into early (<7 days after their first negative culture), and late (≥7 days after their first negative culture) CVC replacement following uncomplicated candidemia. We calculated the median time to CVC removal, clearance of infection, CVC replacement or exchange, and duration of the initial hospitalization. The proportion of patients readmitted within 30 days was also calculated, taking note of the number of candida reinfections. Early replacement occurred in 18 encounters and late replacement in 21 encounters. The median time in both groups to CVC removal was 3 days (P = 0.949), and clearance of infection was 4 days (P = 0.466). The median time to CVC replacement or exchange in the early group was 4 days, compared to 10 days in the late group (P < 0.001). The median duration of the hospitalization in the early group was 12 days compared to 21 days in the late group (P = 0.011). In total 39% of patients from the early group were readmitted within 30 days compared to 57% from the late group (P = 0.359). None of the patients were reinfected with candida within 30 days. Early CVC replacement after uncomplicated candidemia in children with IF decreases hospital stay without increased risk of readmission or reinfection.

Predictors of outcomes in patients with candidemia in an Intensive Care Unit

Objective: Candidemia is a life-threatening infection that causes high mortality rates in intensive care units (ICUs). This study aims to&#x0D; evaluate predictors of the outcome of patients with candidemia in ICU.&#x0D; Patients and Methods: This observational, retrospective study included patients with Candida bloodstream infection (BSI) in ICUs&#x0D; between 6 years of the episode. A binary logistic regression analysis was conducted to inspect the association with mortality.&#x0D; Results: The median age of 74 patients was 68.5, and 53.8% were men. C. parapsilosis was the most frequently isolated fungal species.&#x0D; The 30-day mortality rate was 50%. In the logistic regression model the Acute Physiology and Chronic Health Evaluation (APACHE)&#x0D; II score, positive blood culture on the seventh day, inotropes needed on the day of blood culture positivity, and ventilator-associated&#x0D; pneumonia (VAP) were significant risk factors for the outcome of patients. There was no difference in mortality between an early start&#x0D; of antifungal treatment or central venous catheter removal time.&#x0D; Conclusion: A shift to C. parapsilosis is observed in this study. Host-related factors such as APACHE II score, need for mechanical&#x0D; ventilation or need for inotropes affect mortality more than early treatment and source control in patients with Candida BSI.
