Factors associated with strong opioid use for noncancer pain in patients with chronic intestinal failure.

Chronic analgesic use is described in home parenteral nutrition (HPN)-dependent patients, but there are limited data on factors associated with opioid use for noncancerous pain. Patients attending a national UK intestinal failure reference center were divided in two groups according to strong opioid (SO) usage; risk factors for SO usage were analyzed using logistic regression. A total of 168 HPN-dependent patients were included. During the study period, 73 patients (43.5%) had documented SO usage (SO group), whereas the remainder did not (No-SO group). The prevalence of Crohn's disease among the No-SO group was twofold higher than among the SO group (43.2% vs 24.7%; P = 0.013), whereas those with surgical complications were twice as prevalent among the SO group (19.2% vs 8.4%, respectively; P = 0.04). The rate of working-age unemployment was significantly higher in the SO group (90.6%) than the No-SO group (55.6%; P = 0.001). Multivariate regression showed unemployment as an independent risk factor for SO usage (OR, 6.005; 95% CI, 1.435-25.134), whereas Crohn's disease (OR, 0.284; 95% CI, 0.09-0.898) and <4 intravenous support (IVS) nights per week (OR, 0.113; 95% CI, 0.012-1.009) were protective factors. The life-long incidence of catheter-related bloodstream infection (CRBSI) was comparable between groups (34.2% SO vs 27.4% No-SO; P = 0.336). SO use is frequent among HPN-dependent patients and associated with high rates of unemployment and ≥4 IVS nights per week, but not with increased rate of CRBSI. The reduced usage among patients with Crohn's disease warrants further evaluation but might be due to the chronicity as compared with other IF etiologies.

Catheter-Related Bloodstream Infection With Femoral Central Access Versus Internal Jugular Access in Patients Admitting to Medical Intensive Care Unit.

BackgroundThe current research focused on studying the pattern of catheter-related bloodstream infections (CRBSI) with femoral central access versus internal jugular access in patients admitted to the medical intensive care unit (ICU).MethodsA cross-sectional study was conducted at the Department of Emergency Medicine, Shifa International Hospital, between March 4, 2022, and August 4, 2022. All individuals who presented to the ICU who needed a central venous catheter (CVC) for more than 48 hours were included. Catheter insertion was not permitted if the patient had a history of dermatitis or burns at the site of insertion or if the hemodialysis procedure necessitated the insertion of the catheter into a blood vessel. Three groups of patients were created: group A patients had been diagnosed with CRBSI; group B patients had catheter colonization (CC); and group C did not have CRBSI or CC. Standard microbiological methods were used to identify all of the bacteria collected from the cultures. All data was documented in a predefined pro forma.ResultsOverall, 20 (12.12%) patients had positive CRBSI, 68 (41.5%) had CC, and the remaining 46.3% of cultures were negative. Elderly populations were more prone to acquiring CRBSI showing a significant correlation between older age and CRBSI (p < 0.0001). CC was significantly associated with a longer duration of ICU stay, i.e., 30.3 ± 3.7 (p = 0.003). The absence of both CRBSI and CC was significantly associated with a lower duration of catheterization (11 ± 8.5 days in group C versus 22.1 ± 6.9 and 18.7 ± 7 days in groups A and B, respectively; p < 0.0001). Our study revealed a higher risk of CRBSI when the femoral access was compared to the internal jugular access (58.3% vs. 41.7%; p = 0.0008). The study did not find any significant association of CC with femoral or internal jugular access. Furthermore, a significantly higher rate of negative cultures was reported in patients with internal jugular access as compared to femoral vein access (85.8% vs. 14.2%; p = 0.007).ConclusionThe need for routinely monitoring and observing the microbiological spectrum in patients receiving care in intensive care units is highlighted by the current investigation. The patients with internal jugular vein access had a decreased incidence of CRBSI and CC, while those with femoral access experienced CRBSI more frequently. Escherichia coli and Pseudomonas aeruginosa were the most frequently isolated germs, and both were resistant to various drugs that are used today. It is essential to regularly monitor the epidemiology of CRBSI in order to adopt preventative measures for infection prevention and control, such as staff education, strict hygiene standards, and a higher nurse-to-patient ratio.

Incidence, microbiological aspects and associated risk factors of catheter-related bloodstream infections in adults on chronic haemodialysis at a tertiary hospital in Uganda

The high burden of infectious complications among patients receiving haemodialysis (HD) via central venous catheters increases morbidity and mortality. This study determined the incidence of catheter-related bloodstream infections (CRBSIs), microbiological profile of causative organisms, and associated predictors in patients on chronic HD. A prospective single-centre cohort study of 121 adult patients with end-stage kidney disease was conducted from October 2019 to March 2020. Antibiotic susceptibility was determined by the Kirby-Bauer disk diffusion method. Cox proportional hazards model was used to determine predictors of CRBSI. The mean age was 50 (standard deviation 14.9) years and the median duration of follow-up was 69 (interquartile range 23-124) days. At least one CRBSI was recorded for 41% of patients, at a rate of 5.2 infections per 1000 patient-days. Causative organisms were predominantly Gram-negative bacteria (60.3%), and 36.5% of all isolates were multi-drug resistant. Anaemia [hazard ratio (HR) 5.44, P=0.019, 95% confidence interval (CI) 1.32-22.48] and previous bloodstream infection [HR 2.47, P=0.028, 95% CI 1.10-5.54] were predictors of CRBSI. The high incidence of CRBSI in patients on chronic HD with predominance of Gram-negative bacteria means that catheter care bundles should include Gram-negative coverage.

POS-061 PROFILE AND OUTCOMES OF CATHETER RELATED BLOOD STREAM INFECTIONS IN HEMODIALYSIS CATHETERS

Catheter related blood stream infections (CRBSI) are serious infections in related to hemodialysis (HD) catheters which lead to associated with significant morbidity and catheter loss or even mortality. There is a rise in CRBSI incidence with emergence of drug resistant nosocomial flora.In view of progressively increasing. There is scarce prospective data on incidence, clinical profile and course outcomes of CRBSI in HD catheters. We studied the clinical profile, microbiology, outcomes and factors associated with CRBSI in HD catheters catheters in a tertiary care centre.

Zuragen™ antiseptic catheter lock: A bridge too far?

When sodium citrate is used as an anticoagulant catheter lock the best concentration is 7%, since this provides a density approximately the same as blood. Our laboratory found that the addition of methylene blue and parabens greatly augmented antibacterial properties. Ash Access sponsored a randomized clinical trial in 400 dialysis patients with tunneled CVC, and this showed a significant decrease in incidence of catheter-related bloodstream infection (CRBSI) defined by stringent criteria. The FDA decided that the study missed its primary endpoint, and that the product was mis-classified, so they did not give approval to market. The licensee decided not to appeal to the decision to the physician panel and ended support of the project. Rights to market the catheter lock eventually returned to Ash Access.

Hemodialysis catheter-related bloodstream infections: a single-center experience

Introduction: In hemodialysis (HD) patients, catheter-related bloodstream infections (CRBSI) cause significant morbidity and mortality. Objectives: We analyzed dialysis CRBSI incidence, associated factors, and the spectrum of the causative organisms. Patients and Methods: Patients aged ≥18 years either on maintenance HD or with acute kidney injury having CRBSI (NKF-KDOQI criteria) were included in this prospective observational study and patients with other infections were excluded. Blood, catheter tip culture, and antibiogram were analyzed. All patients were initially treated with antibiotics covering both gram-positive and gram-negative pathogens. Results: Of 921 catheters (882 patients) included, 212 (23%) had CRBSI, of which 69(32.5%) and 143 (67.5%) had culture-positive probable CRBSI and culture-negative possible CRBSI respectively. 131 (61.8%) were &lt;60 years, 133 (62.7%) were males, 177 (83.5%) had diabetes, 141 (66.5%) had leukocytosis and 172(81.1%) had positive procalcitonin. In addition, 193 (91%) had uncuffed catheters and 162 (76.4%) had jugular catheters. Our study showed a CRBSI incidence of 13.39/1000 catheter days, median catheter days, and median time to CRBSI was 40 and 17.2 days respectively. 41 (19.3%) catheters were salvaged (with antibiotic administration or guidewire exchange) and 42 (19.8%) had exit site infection. Gram-positive coagulase-negative Staphylococcus aureus (CoNS) (n=31; 44.9%) followed by extended-spectrum beta-lactamase (ESBL) enteric gram-negative organisms (n=30; 43.4%) were common isolates and remaining had fungal etiology (n=8; 11.7%). In our study, the mortality rate was 6.6% (n=14). Conclusion: The incidence of CRBSI was high in our population. In culture-positive cases, gram-positive organisms contributed marginally higher than gram-negative organisms. CoNS and ESBL enteric gram-negative organisms are the commonest isolates. More than two-thirds of patients with CRBSI had diabetes mellitus and leukocytosis at presentation.

Decreased mortality among patients with catheter-related bloodstream infections at Catalan hospitals (2010–2019)

The incidence of catheter-related bloodstream infections (CRBSIs) has fallen over the last decade, especially in intensive care units (ICUs). To assess the existence of concomitant trends in outcomes and to analyse the current risk factors for mortality. A multicentre retrospective cohort study was conducted at 24 Catalan hospitals participating in the Surveillance of healthcare-associated infections in Catalonia (VINCat). All hospital-acquired CRBSI episodes diagnosed from January 2010 to December 2019 were included. A common protocol including epidemiological, clinical, and microbiological data was prospectively completed. Mortality at 30 days after bacteraemia onset was analysed using the Cox regression model. Over the study period, 4795 episodes of CRBSI were diagnosed. Among them, 75% were acquired in conventional wards and central venous catheters were the most frequently involved (61%). The 30-day mortality rate was 13.8%, presenting a significant downward trend over the study period: from 17.9% in 2010 to 10.6% in 2019 (hazard ratio (HR): 0.95; 95% confidence interval (CI): 0.92-0.98). The multivariate analysis identified age (HR: 1.03; 95% CI: 1.02-1.04), femoral catheter (1.78; 1.33-2.38), medical ward acquisition (2.07; 1.62-2.65), ICU acquisition (3.45; 2.7-4.41), S.aureus (1.59; 1.27-1.99) and Candida sp. (2.19; 1.64-2.94) as risk factors for mortality, whereas the mortality rate associated with episodes originating in peripheral catheters was significantly lower (0.69; 0.54-0.88). Mortality associated with CRBSI has fallen in recent years but remains high. Intervention programmes should focus especially on ICUs and medical wards, where incidence and mortality rates are highest.

The effectiveness of a dedicated central venous access care team to prevent catheter-related bloodstream infections

Background: Catheter-related bloodstream infection (CRBSI) rates remain high despite the use of an insertion bundle. We hypothesized that line care and maintenance by a dedicated team would help decrease CRBSI rates. This study was conducted in The Medical City (TMC), is a 526-bed, private, tertiary-care center in Pasig City, Philippines. Methods: All adult hospitalized patients from October 1, 2020, to October 31, 2021, with a newly inserted temporary central venous catheter (CVC) were eligible for inclusion. CRBSI rates before the intervention (October 2019 to March 2020) and after the intervention (April to October 2021) were compared. The intervention arm consisted of a dedicated central venous access team (CVAT) who provided education and performed daily line care and dressing changes per protocol. A series of χ2 and Wilcoxon rank-sum tests were performed to compare characteristics between exposure groups. Incidence rates of CRBSI before and after the intervention were compared using an incidence rate ratio approach. Results: In total, 209 CVCs were enrolled in the study, with 103 CVCs (49.28%) in the preintervention arm and 106 CVCs (50.72%) in the postintervention arm. Baseline patient characteristics were similar. CRBSIs were more frequent in the preintervention arm than the postintervention arm (39 of 103 vs 28 of 106; P = .08). The CRBSI incidence density rate was higher in the preintervention arm than the postintervention arm, but the difference was not statistically significant (37.46 per 1,000 patient days vs 25.97 per 1,000 patient days; P = .14). Median time to CRBSI was similar in both groups (9 vs 8 days). Conclusions: Baseline CRBSI rates were high and risk of infection increased by day 8 after line insertion. We detected a decreasing trend in rates of CRBSI with a dedicated CVAT, but multiple interventions are likely needed to influence overall rates.Funding: NoneDisclosures: None

Comparison of Efficacy of 2% Chlorhexidine Gluconate-Alcohol and 10% Povidone-Iodine-Alcohol against Catheter-Related Bloodstream Infections and Bacterial Colonization at Central Venous Catheter Insertion Sites: A Prospective, Single-Center, Open-Label, Crossover Study.

An effective antiseptic agent is an essential component of a central venous catheter (CVC) care bundle, to protect against catheter-related bloodstream infections (CRBSIs). We conducted a trial to compare the incidences of CRBSI and the growth of insertion site flora in patients with CVC using 2% chlorhexidine gluconate–alcohol (CHG) or 10% povidone-iodine–alcohol (PVI) in the CVC care bundle. Patients who were admitted to two medical intensive care units (ICUs) and had CVC placement for >48 h were enrolled. Using a two-way crossover design with two six-month interventions, the ICUs were assigned to use either CHG or PVI in their care bundles. A total of 446 catheters in 390 subjects were enrolled in the study. The detection rate of flora was greater in the PVI group on both day 7 (26.6% versus 6.3%, p < 0.001) and day 14 (43.2% versus 15.8%, p < 0.001). The incidence rate of CRBSI was higher in the PVI group compared to the CHG group (2.15 vs. 0 events per 1000-catheter-days, p = 0.001), although the significance was lost in the multivariate analysis. In conclusion, 2% CHG was superior to 10% PVI in the CVC care bundle in terms of the inhibition of skin flora growth at CVC insertion sites and was potentially associated with lower incidence rates of CRBSI.

A Meta-Analysis of Incidence of Catheter-Related Bloodstream Infection with Midline Catheters and Peripherally Inserted Central Catheters.

In order to provide reference for the prevention and treatment of CRBSI during clinical intravenous infusion therapy, this paper investigates the incidence of catheter-related bloodstream infection (CRBSI) in the treatment of midline catheters (MCs) and peripherally inserted central catheters (PICCs) by intravenous infusion. Web of Science, PubMed, Scopus, Embase, Cochrane Library, and ProQuest are searched to collect CRBSI-related studies on MC and PICC. The retrieval time is from the database construction to August 2020. Two researchers independently searched and screened literature quality evaluation and extracted data according to inclusion and exclusion criteria, and RevMan 5.3 software was used for analysis. Eleven studies are included, with a total of 33809 patients. The incidence of CRBSI in the MC group is 0.599% (43/7079), and that in the PICC group is 0.4993% (133/26630). Meta-analysis showed that the incidence of CRBSI in the MC group is higher than that in the PICC group (OR = 0.72, 95% CI = 0.43–1.08, P=0.11), and the difference is statistically significant when low-quality studies are excluded (OR = 0.60, 95% CI = 0.39–0.93, P=0.02). There is no significant difference in the incidence of CRBSI between MC group and PICC group (P > 0.05), American subgroup (OR = 0.52), and British subgroup (OR = 4.86), the results of the two groups are opposite, and the incidence of CRBSI between the MC group and PICC group is statistically significant. There is no significant difference in the incidence of CRBSI between the adult and other subgroups (all P > 0.05). There is no significant difference in the incidence of CRBSI between the MC group and the PICC group (P > 0.05). Overall, the inter-study stability is general, the quality is good and the medium is good, and there is no obvious publication bias. The risk of CRBSI in MC and PICC is systematically evaluated and meta-analyzed for the first time. The incidence of CRBSI in MC group is lower than that in PICC group during intravenous infusion therapy. Under the same conditions, MC patients can be given priority for intravenous infusion therapy. More high-quality and child-related studies are needed to further evaluate and explore the risk of CRBSI between MC and PICC.

Longitudinal evolution of catheter-related bloodstream infections, kidney function and liver status in a nationwide adult intestinal failure cohort

Objectives The development of intestinal failure-related complications in Finnish adults is unknown. This study aimed to investigate the incidence of catheter-related bloodstream infections (CRBSI), and the longitudinal changes in biochemical liver and kidney tests in a nationwide cohort. Materials and methods The search for Finnish adults with intestinal failure (IF) utilized a survey to Finnish health-care providers (n = 111) with the potential to provide long-term parenteral support (PS) for adult IF. Our nationwide, cross-sectional cohort included all IF patients aged ≥ 18 years who had received PS for ≥ 120 d in 2017. Data regarding CRBSI and biochemical liver and kidney tests were collected from patient records at the start of PS up to the latest available measurement in 2017. Results In the nationwide cohort of 52 patients, the CRBSI incidence was 1.35/1000 catheter days. Seventy-three percent of CRBSI in a long-term catheter led to catheter replacement. During a median PS duration of 27.5 (interquartile range [IQR] 11.3–57.3) months, a statistically significant median change occurred in estimated glomerular filtration rate (eGFR; −8.5 ml/min/1.73 m2, IQR −30–7, p = .005) and alkaline phosphatase (ALP; 26 U/l, IQR −11–95, p = .019). In a multiple regression model for eGFR at data collection, baseline eGFR and age were strong explanatory variables. Conclusions Incidence of CRBSI, but not treatment strategies, in this nationwide adult IF population correspond well to those reported from specialized centers. Decreased kidney function and abnormal liver test results are frequent findings, and even more so over time, emphasizing the importance of regular monitoring.

Association between hospital and ICU structural factors and patient outcomes in China: a secondary analysis of the National Clinical Improvement System Data in 2019

BackgroundHospital and ICU structural factors are key factors affecting the quality of care as well as ICU patient outcomes. However, the data from China are scarce. This study was designed to investigate how differences in patient outcomes are associated with differences in hospital and ICU structure variables in China throughout 2019.MethodsThis was a multicenter observational study. Data from a total of 2820 hospitals were collected using the National Clinical Improvement System Data that reports ICU information in China. Data collection consisted of a) information on the hospital and ICU structural factors, including the hospital type, number of beds, staffing, among others, and b) ICU patient outcomes, including the mortality rate as well as the incidence of ventilator-associated pneumonia (VAP), catheter-related bloodstream infections (CRBSIs), and catheter-associated urinary tract infections (CAUTIs). Generalized linear mixed models were used to analyse the association between hospital and ICU structural factors and patient outcomes.ResultsThe median ICU patient mortality was 8.02% (3.78%, 14.35%), and the incidences of VAP, CRBSI, and CAUTI were 5.58 (1.55, 11.67) per 1000 ventilator days, 0.63 (0, 2.01) per 1000 catheter days, and 1.42 (0.37, 3.40) per 1000 catheter days, respectively. Mortality was significantly lower in public hospitals (β = − 0.018 (− 0.031, − 0.005), p = 0.006), hospitals with an ICU-to-hospital bed percentage of more than 2% (β = − 0.027 (− 0.034, -0.019), p < 0.001) and higher in hospitals with a bed-to-nurse ratio of more than 0.5:1 (β = 0.009 (0.001, 0.017), p = 0.027). The incidence of VAP was lower in public hospitals (β = − 0.036 (− 0.054, − 0.018), p < 0.001). The incidence of CRBSIs was lower in public hospitals (β = − 0.008 (− 0.014, − 0.002), p = 0.011) and higher in secondary hospitals (β = 0.005 (0.001, 0.009), p = 0.010), while the incidence of CAUTIs was higher in secondary hospitals (β = 0.010 (0.002, 0.018), p = 0.015).ConclusionThis study highlights the association between specific ICU structural factors and patient outcomes. Modifying structural factors is a potential opportunity that could improve patient outcomes in ICUs.

Postoperative Rather Than Preoperative Neutropenia Is Associated With Early Catheter-related Bloodstream Infections in Newly Diagnosed Pediatric Cancer Patients.

The relationship of early catheter-related bloodstream infections (CRBSIs) with perioperative neutropenia and antibiotic prophylaxis is not well established. We sought to evaluate perioperative factors associated with early CRBSIs in newly diagnosed pediatric cancer patients, particularly hematologic indices and antibiotic use. We retrospectively reviewed national registry records of newly diagnosed pediatric cancer patients with port-a-caths inserted using standardized perioperative protocols where only antibiotic use was not regulated. Thirty-day postoperative CRBSI incidence was correlated with preoperative factors using logistic regression and with postoperative blood counts using linear trend analysis. Among 243 patients, 17 CRBSIs (7.0%) occurred at median 14 (range, 8-28) postoperative days. Early CRBSIs were significantly associated with cancer type [acute myeloid leukemia and other leukemias (AML/OLs) vs. solid tumors and lymphomas (STLs): odds ratio (OR), 5.09; P = 0.0036; acute lymphoblastic leukemia vs. STL: OR 0.83; P = 0.0446] but not preoperative antibiotics, absolute neutrophil counts and white blood cell counts. Thirty-day postoperative absolute neutrophil counts and white blood cell trends differed significantly between patients with acute lymphoblastic leukemia and STLs (OR 0.83, P < 0.05) and between AML/OLs and STLs (OR 5.09, P < 0.005), with AML/OL patients having the most protracted neutropenia during this period. Contrary to common belief, low preoperative absolute neutrophil counts and lack of preoperative antibiotics were not associated with higher early CRBSI rates. Instead, AML/OL patients, particularly those with prolonged neutropenia during the first 30 postoperative days, were at increased risk. Our findings do not support the use of empirical preoperative antibiotics and instead identify prolonged postoperative neutropenia as a major contributing factor for early CRBSI.

Atomic force microscopy and scanning electron microscopy as alternative methods of early identification of pathogens causing catheter-related bloodstream infections of patients in ICU

Abstract Introduction Vascular catheters are an indispensable element of the therapy of patients in intensive care. Their use is associated with the possibility of complications, including infectious. According to various sources, the incidence of catheter-related bloodstream infections (CRBSIs) ranges from 0.1 to 22.7 per 1,000 catheter days. Materials and Methods The central venous catheter tip culture samples were collected from 24 patients with suspected catheter-related bloodstream infection, from three intensive care units (ICUs). The results of microscopic examinations: atomic force microscope (AFM) and scanning electron microscope (SEM) were compared with the results of microbiological analysis of the central venous catheter tip and blood collected from the catheter. Results The microscopic examination and microbiological analysis of both the blood and central venous catheter samples confirmed the presence of microorganisms in 16 cases (double positive result). Our study was conducted in a short period of time (up to 6 hours) and it gave an initial answer to the question about the type of microorganisms colonising the central venous catheter. In one patient the infection was not caused by removal of the central venous catheter. However, not all results were fully consistent within the two diagnostic methods. The colonisation of the central venous catheter with Pseudomonas aeruginosa and Staphylococcus epidermidis was microbiologically confirmed, but it was not confirmed by the microscopic examination of the sample collected from patient No. 20. However, the examination enabled preliminary assessment of the microorganism colonising the catheter, which may have caused the blood infection. It cannot be ruled out that Pseudomonas aeruginosa bacilli were grown on the catheter that came into contact with blood from another source of infection, e.g. the respiratory, nervous or urinary systems. Information on the presence of cocci-shaped bacteria forming characteristic clusters or rods may enable initial diagnosis of catheter-related bloodstream infection if it is accompanied by typical clinical symptoms. Alternative diagnostics also provides valuable information on the presence of biofilm, which is a factor hindering the body’s response to infection and penetration of antibiotics. Conclusions Our pilot study presents new diagnostic possibilities of microscopic imaging with the atomic force microscope (AFM) and scanning electron microscope (SEM) to identify pathogens on routinely used disposable medical devices, such as the central venous catheter. On the other hand, this range of diagnostics reveals the potential to constantly improve medical materials which come into direct contact with patients’ tissues. It is important to create a database of microscopic images, which would be a repeatable diagnostic pattern and fully correlated with the results of microbiological analysis, because it would facilitate initial quick diagnosis of a potential CRBSI.

The use of parenteral nutrition is not associated with an increased incidence of catheter-related bloodstream infection (CRBSI) in hospital setting

Rationale: Catheter-related bloodstream infection (CRBSI) is a complication of great impact in patients using Parenteral Nutritional (PN). Historically, PN is considered a risk factor that increases CRBSI rates. However, strict adherence to systematic protocols established by the Nutritional Support Team (NST) can contribute to controlling infections. Therefore, our objective is to evaluate the CRBSI incidence in PN and non-PN patients in a high complexity hospital in Brazil simultaneously, and compare both results.

Scoping review on prevention of central venous catheter-related bloodstream infection in burn patients

Objective: To investigate the research trend and scope of prevention of central venous catheter-related bloodstream infection (CRBSI) in burn patients. Methods: The scoping review method was adopted. Pre-retrieval was carried out with search terms of ", , " and "central venous catheter, infection, catheter-related bloodstream infection, burn". On the basis of pre-retrieval, different retrieval formulas were formulated to retrieve researches related to central venous CRBSI in burn patients in China National Knowledge Internet, Wanfang Database, VIP Database, PubMed, Embase, CINAHL, and Cochrane Library from the establishment of each database to August 2020. Data were extracted from the included literature, including the first author, research publication time, research country, research type, diagnosis basis and intervention measures of central venous CRBSI, research sample selection, incidence related to infection, and research conclusion. Results: A total of 20 randomized controlled trials, quasi-experimental studies, case-control studies, cohort studies, and implementation researches published in 1990-2020 were included in this study with the first authors from China, the United States of America, or Argentina. The diagnostic bases for central venous CRBSI in burn patients were not uniform in the included literature, including adopting the Guidelines of American Centers for Disease Control and Prevention, Diagnostic Criteria for Nosocomial Infection, and other diagnostic criteria without specifying the source. The intervention measures included the use of new materials such as antibiotics coated catheter and ethanol impregnated port protectors, multidisciplinary cooperation, and comprehensive preventive measures. The sample size in the included literature was small, and the sample selection was different, including the number of patients and the the number of placement of central venous catheter. The outcome indicators for infection in the included literature were diversified. The incidence per 1 000 days of central venous CRBSI was 20.41‰-29.1‰ of patients in control group in China, the incidence per 1 000 days of central venous CRBSI was mostly <16.6‰ in control group in foreign countries, and the incidence of central venous CRBSI was decreased to varying degrees after implementing the corresponding intervention measures. Related research conclusions showed that new materials, multidisciplinary cooperation, and comprehensive preventive measures had good effects on prevention of central venous CRBSI in burn patients. Conclusions: The researches on prevention of central venous CRBSI in burn patients in China start early and the research types are diversified. The diagnostic criteria of central venous CRBSI in burn patients are not uniform, intervention measures have shifted from standardizing relevant operational measures to exploring the prevention effects of new materials, multidisciplinary cooperation, and multiple measures, and the latter has good effects on preventing central venous CRBSI in burn patients.

Increase in the frequency of catheter-related bloodstream infections during the COVID-19 pandemic: a plea for control

BackgroundThe incidence of nosocomial infections including ventilator-associated pneumonia and bacteraemia has been described during the COVID-19 pandemic. However, information regarding the impact of COVID-19 on the incidence of catheter-related bloodstream infections (CR-BSIs) is very limited.AimTo evaluate the impact of the COVID-19 pandemic in the evolution of CR-BSIs in a large hospital.MethodsThis was a retrospective study comparing the incidence, aetiology and outcome of CR-BSIs during the months of March to May 2019 (pre-pandemic) and 2020 (during the pandemic).FindingsThe number of patients with one or more CR-BSIs in 2019 and 2020 were 23 and 58, respectively (1.89 vs 5.53/1000 admissions); P<0.001. Median time from catheter implantation to demonstration of CR-BSI was 27.5 days (range 11.75–126.00 days) in the 2019 cases and 16.0 days (range 11.00–23.50 days) in the 2020 population (P=0.032).ConclusionsA dramatic increase of CR-BSIs was found during the COVID-19 pandemic. Reinforcement of classic and new preventive measures is necessary.

Outcome of adult patients receiving parenteral support at home: 36 years’ experience at a tertiary referral centre

Patients with intestinal failure often need long-term home parenteral support (PS). We aimed to determine how the underlying diagnosis, complications and survival had changed over the last 36 years in the UK's largest IF centre. 978 adult home PS patient records were analysed from January 1979 until October 2016. The age, sex, underlying aetiology, complications and survival was compared over 5-year periods. Pre-1990 to 2011-2016, numbers increased from 29 to 451, the mean age of patients increased from 31±16.5 to 52±17.6 years. The percentage of patients with IF due to surgical complications increased (3.4%-28.8%, p<0.001)), while those with inflammatory bowel disease decreased (37.9%-22.6%, p<0.001). Complication of home PS reduced: catheter related blood stream infections (CRBSI) 71.4% to 42,2%, CVC thrombosis 34.5%-5.3%. Intestinal failure associated liver disease (IFLAD) 10.3%-1.8%. Patients with dysmotility, scleroderma and a congenital aetiology had the highest incidence of CRBSI and CVC Thrombosis. Overall survival was greater pre-1995 [HR 0.2-0.4 (p=0.02)] most likely associated with an increase in mean age. Survival for patients without malignancy was 90%, 66%, 55%, 45%, 33% and 25% at 1,5, 10, 15, 20 and 30 years respectively. Multivariate analysis demonstrated a relationship between survival and age of starting home PS; type of home PS; presence or absence of the colon in continuity; and underlying aetiology. Demand for home PS is increasing in particular for advanced malignancy, post-surgical complications and older more co-morbid patients. Complications of home PS are reducing over the last 30 years and 10-year survival for non-malignant aetiologies improving. Survival and changes in aetiology in intestinal failure.

Catheter‐related infection rates in patients receiving customized home parenteral nutrition compared with multichamber bags

AbstractBackgroundThe risk of bloodstream infections may be increased in hospitalized patients receiving ready‐made parenteral nutrition (PN) multichamber bags (MCBs) compared with customized PN; however, as highlighted in recent international guidelines, there are no comparable data relating to home PN (HPN).MethodsData from a prospectively maintained database were analyzed to compare incidence rates of catheter‐related bloodstream infections (CRBSIs) between patients receiving customized HPN compared with MCB HPN at a national UK referral center between May 2018 and August 2020.ResultsSixty patients with chronic intestinal failure were commenced on MCBs and 45 received customized HPN for a total of 5914 and 7641 catheter days, respectively. No difference in CRBSI incidence was found (0.51/1000 catheter days for MCBs, 0.39/1000 catheter days for customized HPN; incidence rate ratio, 1.29; 95% CI, 0.26–6.37). Eighteen patients were switched from customized HPN to MCB HPN. The study period covered 7401 catheter days receiving customized HPN and 4834 days on MCBs. No significant change was noted in the CRBSI rates following this switch (0.27/1000 catheter days receiving customized HPN vs 0.21/1000 catheter days on MCBs; incidence rate ratio, 1.31; 95% CI, 0.12–14.3).ConclusionThe use of MCBs for HPN patients is not associated with an increased risk of CRBSI. This study will inform international guidelines and provide reassurance for the continued, safe use of MCB HPN.
