Incidence Of Catheter-related Bloodstream Infection Research Articles

Duration of antibiotic therapy in central venous catheter-related bloodstream infection due to Gram-negative bacilli.

The aim of this study was to review recent data evaluating the duration of antibiotic therapy in central venous catheter-related bloodstream infection (CRBSI) due to Gram-negative bacilli (GNB). CRBSI is the most common complication associated with the use of intravascular catheters. CRBSI directly contributes to increase additional days of hospitalization, morbidity and therefore economic costs.The incidence of GNB CRBSI has been increasing considerably in the last years; this has raised a concern due to the high reported rate of multi drug resistant bacteria in these infections what poses a considerable challenge for effective treatment. However, there are no specific guidelines for management of GNB-CRBSI and optimal treatment duration has not been clearly defined.Recent studies evaluating the impact of the duration of antibiotic therapy of GNB-CRBSI have shown that short-course antibiotic therapy might be as effective as long-course therapy once the central venous catheter (CVC) has been removed. CRBSI due to GNB has shown a rapid increase in the last years. Current guidelines recommend antibiotic treatment for at least 7-14 days, although no randomized clinical trials have evaluated the optimal duration of antibiotic therapy for GNB-CRBSI. Recent data suggest that administration of appropriate antibiotic therapy for 7 days or less may be as well tolerated and effective as longer courses in episodes of GNB-CRBSI, once the CVC has been removed.

Subcutaneously anchored securement for peripherally inserted central catheters: Immediate, early, and late complications.

An adequate stabilization of a vascular device is an important part of insertion bundles and is an effective strategy in reducing complications. Dislodgment has a relevant clinical impact and an increase in healthcare costs. We have retrospectively investigated the safety and efficacy of Subcutaneously Anchored Securement (SAS) for Peripherally Inserted Central Catheters (PICC) in cancer patients. We analyzed 639 patients who had a PICC inserted and secured with SAS, over the past 3 years (2018-2020). No immediate complications during SAS placement were reported. In the first 24-48 h, a slight local ecchymosis was reported in 24 cases with rapid spontaneous resolution. No cases of bleeding or hematoma of the exit site were reported. The total number of catheter days was 93078. Dislodgment occurred only in seven cases (1.1%). In 16 patients, the PICC was removed because of catheter-related bloodstream infection (CRBSI): the overall incidence of CRBSI was 0.17 per 1000 catheter days. Symptomatic venous thrombosis was documented in 12 patients (1.9%) and treated with low molecular weight heparin without PICC removal. We had no cases of irreversible lumen occlusion. In 17 patients, local discomfort-including device-related pressure ulcers and painful inflammation-was reported: these cases were treated without SAS removal or PICC removal. In this retrospective analysis, subcutaneously anchored securement of PICCs was a safe and effective strategy for reducing the risk of dislodgment.

Comparison of ethanol lock and heparin lock solution as prevention of catheter-related bloodstream infection in hemodialysis patients: systematic review and meta-analysis of randomized controlled trials

Introduction: Catheter-related bloodstream infection (CRBSI) is a common complication of catheter use for vascular access in hemodialysis patients and a major cause of morbidity and mortality. Preventive measures, including antibiotic lock, are inadequate due to the risk of resistance and insufficient effect against bacterial biofilm. Ethanol, an antimicrobial substance, is a potential prophylactic lock-in preventing CRBSI. This study aims to assess ethanol lock's effectiveness in preventing CRBSI in hemodialysis patients with a catheter as vascular access and its impact on catheter dysfunction. Methods: Researchers systematically searched online databases including Pubmed, Cochrane Library, and Science Direct for relevant randomized controlled trials (RCTs) published within 2011 until 2020. Relevant data were pooled in PICOs (Population, Intervention, Control, Outcomes) format and analyzed with Review Manager (version 5.3.5, Cochrane Collaboration, Denmark). Results: Seven RCTs involving 453 patients were assessed. The primary outcome indicates that prophylactic ethanol lock significantly reduces the incidence of CRBSI compared to that of heparin lock (RR=0.32, 95% CI 0.12-0.83, p=0.02, heterogeneity I2=68%). The secondary outcome suggests no significant difference in the incidence of catheter dysfunction in ethanol lock and heparin lock (RR=0.75, 95% CI 0.23-2.40, p=0.63, heterogeneity I2=68%). Conclusion: Ethanol is a potential prophylactic lock agent in preventing CRBSI in hemodialysis patients with catheter access. Further research is needed to synchronize the procedural use of ethanol lock and evaluate its long-term effect.

Biofilm and catheter-related bloodstream infections.

Careful attention to detail and adherence to procedure guidelines when inserting and managing intravascular catheters has decreased the incidence of catheter-related bloodstream infections (CRBSIs). In order to limit these, health professionals must understand the underlying microbiology. Biofilms can explain the clinical findings most often seen with CRBSIs, yet they are poorly understood within medicine. Bacteria growing on solid surfaces such as a catheter are predominantly in biofilm phenotype, with a group of genes active that allow the bacteria to be tolerant to antiseptics and antibiotics by producing a self-secreted protective matrix. It is unclear whether it is planktonic seeding or small fragments of biofilm breaking off into the bloodstream that eventually results in the acute infection. The literature identifies four routes for microbes to adhere to a catheter and start biofilm formation: catheter contact, catheter insertion, catheter management and non-catheter-related sources. Routine clinical culture methods are inadequate to fully identify microbes producing catheter biofilm and/or bloodstream infection, therefore DNA methods may be required to diagnose CRBSIs. Treatment is removal and reinsertion of the catheter in a different site when possible. However, antibiofilm strategies can be employed to try to salvage the catheter. The use of high-dose antiseptics or antibiotics for long durations inside the catheter and hub (antibiotic/antiseptic lock) can suppress biofilm enough to reduce the seeding of the blood below a level where the patient's immune system can prevent bloodstream infection.

Design and application of Checklist for quality control in intensive care unit

To design a Checklist for quality control in intensive care unit and observe the effect of clinical application. By consulting guidelines and literature, such as Critical care medicine professional medical quality control index (2015 edition), the quality control Checklist of intensive care unit was designed. It included four parts: quality control data collection, medical record quality verification, special diagnosis and treatment, and hospital infection prevention and control supervision. Every month, a doctor with a senior professional title served as the quality control director, and was responsible for the quality control of the department's medical care, including collecting data of the past 24 hours during the morning handover, discussing and registering special diagnosis and treatment behaviors that would be performed on the day, and coordinating with the nursing team leader, controlling the quality of the whole department throughout the day, such as supervising each medical staff if they had unreasonable behaviors, checking the running and discharge medical records, and inspecting the status of the staff on duty. The data in 2018, 2019 (Checklist implemented) and 2017 (Checklist not implemented) were retrospectively analyzed, including the status of admitted patients, department management information, length of intensive care unit (ICU) stay, and the incidence of three-tube infection [ventilator-associated pneumonia (VAP), catheter-related bloodstream infection (CRBSI), catheter-associated urinary tract infection (CAUTI)], and standardized mortality, etc. From 2017 to 2019, the number of patients admitted was 373, 446, and 480, with annual growth of 19.57% and 7.62% in 2018 and 2019, respectively, and an increase of 28.69% in 2019 compared with 2017. There was no statistically significant difference in the average age and acute physiology and chronic health evaluation II (APACHE II) of patients in the three years. Compared with 2017, the length of ICU stay of patients in 2018 and 2019 were significantly shortened (days: 8.99±6.12, 9.14±7.02 vs. 10.20±7.21), and the incidence of VAP, CRBSI and CAUTI were significantly reduced [VAP (cases/1 000 ventilation days): 12.97±3.60, 9.62±3.14 vs. 17.48±4.89, CRBSI (cases/1 000 catheter days): 3.75±2.19, 3.87±1.87 vs. 6.19±3.13, CAUTI (cases/1 000 catheter days): 3.29±2.18, 3.28±1.87 vs. 5.61±3.18]. The standardized mortality were also significantly reduced [(77.27±7.24)%, (70.61±7.49)% vs. (84.41±9.05)%], the number of non-compliance with hospital infection prevention per month decreased significantly (person times: 54.00±6.30, 41.08±10.76 vs. 72.08±19.68), and the number of special diagnosis and treatment per month increased significantly (person times: 1 056.67±235.27, 1 361.75±278.48 vs. 722.25±145.96), the rate of etiology submission before antimicrobial treatment [(93.21±3.68)%, (96.59±2.49)% vs. (87.86±5.28)%] and deep vein thrombosis (DVT) prevention rate [(91.13±6.36)%, (96.23±2.99)% vs. (85.58±7.68)%] were significantly improved, and all the differences were statistically significant (all P < 0.05). All medical records in the three years were Grade A, but the average scores in 2018 and 2019 were higher than those in 2017 (96.82±2.84, 96.73±2.94 vs. 93.70±3.33, both P < 0.01). Compared with 2018, the incidence of VAP, the rate of etiology submission before antimicrobial treatment, the DVT prevention rate, and the standardized mortality rate in 2019 were further improved, and the number of non-compliance with hospital infection prevention per month decreased and the number of special diagnosis and treatment per month increased, and the differences were statistically significant (all P < 0.05). The application of quality control Checklist in intensive care unit can build an effective quality control system, reduce the incidence of three-tube infection, standardized mortality and length of ICU stay, improve the quality control awareness and execution of medical staff, and promote the improvement of medical quality.

Incidence and risk factors of central line catheter-related bloodstream infections.

Central line catheter-related bloodstream infections (CLABSI) burdens great morbidity, mortality and unnecessary hospital expenses. Studies related to its incidence and epidemiological and clinical profile among neonates in Peru are scarce, not being clear it's actual impact. A prospective cohort study was conducted in a neonatal intensive care unit (ICU) of a public hospital in Lima, Peru between 2017-2018. 167 patients were included (52,7% male) with gestational age between 24-41 weeks, obtaining 1999 catheter-days and 16 cases of CLABSI. The incidence rate was 8/1000 catheter-days. Use of umbilical catheter (p=0,005) and multiple catheters (p<0,001) both showed a statistically significant correlation regarding the development of CLABSI. It's necessary to extend the study to other ICUs and stablish solid, efficient and long-lasting system of CLABSI surveillance that allows the evaluation of possible interventions to reduce the incidence of CLABSI.

The appropriate frequency of dressing for percutaneous central venous catheters in preventing catheter-related blood stream infection in NICU – A randomized controlled trial

Complications of percutaneous central venous catheters (PCVCs) include catheter-related blood stream infection (CRBSI), occlusion, leakage, and phlebitis, which may lead to sepsis or prolonged hospitalization. The primary objective of this randomized controlled trial was to determine the appropriate frequency of dressing for percutaneous central venous catheters in preventing CRBSI, every week regularly vs. non-regularly, in premature neonates in NICU. Patients in NICU requiring PCVCs from March 2019-May 2020 were enrolled. Enrolled patients were randomly assigned into 2 groups: regular dressing group (RD), for which dressings were changed every week regularly, or additionally when oozing was noticed; and non-regular dressing group (ND), for which dressings were changed only when oozing was visible. The incidence of CRBSI, occlusion, leakage, and phlebitis were compared between the two groups using the Chi-squared test. The incidence of catheter-related complications was defined as numbers of episodes per 1000 catheter-days. A total of 197 PCVCs were enrolled. The ND and RD groups had 99 and 98 PCVCs, respectively. The average CD interval was 9.3 days in ND group and 5.8 days in RD group. The incidence of CRBSI in RD group was 0‰, which was significantly lower than that of ND group, which was 2.0‰ (p=0.048), but no significant differences were found between groups in the incidence of occlusion, leakage, and phlebitis of PCVCs. Regular dressing changes every week and when oozing occurs while maintaining the protocol of maximum sterile barrier precautions is the best method and frequency of dressings of PCVCs.

Substitution of citrate with tissue plasminogen activator (rt-PA) for catheter lock does not improve patency of tunnelled haemodialysis catheters in a randomised trial

BackroundThe study aim was to establish if substitution of citrate with rt-PA for catheter lock once weekly can reduce the incidence of catheter-related blood stream infections (CR-BSI) or improve patency of tunneled haemodialysis catheters.MethodsAll incident patients undergoing insertion of a tunneled haemodialysis catheter were screened and included except those suffering infection or using oral anticoagulation. Study participants were randomized into two arms according to the solution applied as catheter lock: receiving either trisodium citrate (Citra-LockTM 4%) only or rt-PA (Actilyse® 1 mg/ml) on the middle session each week with citrate used on the first and third sessions. The incidence of CR-BSI (confirmed by positive blood culture), catheter non-function (complete obstruction), and malfunction (blood flow < 250 ml/min) was recorded. Statistical significance was tested with ANOVA, post hoc analysis was performed by means of multiple linear regression.ResultsTotally, 18 patients were included and followed during 655 haemodialysis sessions. No episode of CR-BSI was detected while 6 catheter non-functions (0.9% sessions) and 101 malfunctions (15.4% sessions) were recorded. The incidence of both events was equal between the study arms: 4 non-functions and 55 malfunctions in the rt-PA arm and 2 non-functions and 46 malfunctions in the citrate arm (p = 0.47 and p = 0.24, respectively). Additionally, the mean blood flow achieved did not differ significantly between the arms: 326 ± 1,8 and 326 ± 1,9 ml/min (p = 0.95) in rt-PA and citrate arms, respectively. Post hoc analysis identified time elapsed since previous session (β = 0.12, p = 0.005) and malfunction on previous session (β = 0.25, p < 0.001) as significant factors affecting the occurrence of malfunction. By contrast, the study arm, rt-PA application on previous session, and catheter vintage did not enter the model.ConclusionSubstitution of citrate with rt-PA for catheter lock does not reduce the incidence of catheter malfunction neither does it affect the blood flow achieved during haemodialysis. Catheter patency is related rather to the time interval between sessions and to previous malfunction (thus probably reflecting undefined individual factors). The incidence of CR-BSI within pre-selected haemodialysis population is sporadic (less than 1 per 4.3 patient years in our sample).Trial registrationAustralian New Zealand Clinical Trials Registry, ACTRN12612000152820.

Repair of central venous access devices in intestinal failure patients is safe and cost-effective: A retrospective single centre cohort study

Patients with chronic intestinal failure (IF) require home parenteral nutrition (HPN). Central venous access is needed for prolonged use of PN, usually via a long term central venous access device (CVAD). Post insertion there may be mechanical complications with a CVAD such as catheter rupture or tear. Repair of damaged CVADs is possible to avoid risks associated with catheter replacement in patients with IF. However, catheter related blood stream infections (CRBSI) are a concern when CVAD's are accessed or manipulated. To investigate the success of repair of CVADs in patients with IF on HPN, related to repair longevity and incidence of CRBSI following repair. Nutrition team records of CVAD repairs carried out in patients with IF were reviewed retrospectively for the period April 2015 to March 2019. Nutrition Clinical Nurse Specialists carried out 38 repairs in 27 patients. Male n=5, female n=22; mean age 55 years. Catheter longevity before first repair (n=27): median 851 days, IQR 137-1484 days. 30/38 (78.9%) of repairs were successful lasting ≥30days. Hospital admission was avoided in 76% of cases. 4 patients in the failed repair group underwent catheter re-insertion where 4 had a further, subsequently successful, repair, an overall success rate of 89.4% (34/38). 30-day CRBSI rate was 0.09/1000 catheter days in repaired catheters. In comparing costs, there is a potential cost saving of 2766GBP for repair compared to replacement of damaged CVADs. Repair of tunnelled CVADs in patients with IF is successful and safe with no increased risk of CRBSI. Significant cost savings may be made.

Long-term outcomes of various pediatric short bowel syndrome in China.

The goal of this study was to analyze long-term outcome of various pediatric short bowel syndrome (SBS) at an intestinal rehabilitation center in China. One hundred and fifty-seven children with SBS were enrolled in this study from October 1988 to July 2019. Their long-term follow-up outcome was analyzed according to the age of disease onset, parenteral nutrition (PN) duration, and anatomic types of short bowel, respectively. The clinical characteristics, which included demographics, the length of residual small bowel, PN duration, PN dependence, SBS-related complications such as IF-related liver disease (IFALD), catheter-related bloodstream infection (CRBI), and mortality were compared among the groups. The main etiology for SBS were intestinal atresia, NEC, and volvulus. Five of 157 patients did not wean off PN. The incidence of IFALD and CRBI was 24.2 and 22.3%, respectively. Sixteen cases died because of infection and liver failure and eight patients lost to follow-up. The survival rate of the 157 patients was 84.7%. PN duration was longer in the infants and children group (284 ± 457d vs. 110 ± 64d, P = 0.021; R = 0.264, P = 0.001) and more patients did not wean off PN than in the neonates group (11.6% vs. 0, P = 0.001; R = 0.295, P < 0.001). Patients with PN with a duration of longer than 90days had more CRBIs (30.6%, P = 0.025; R = 0.236, P = 0.003). Additionally, the rate of CRBI was higher in patients with stoma (30.0%, P = 0.032). There was no difference in mortality among the groups. In five PN dependence patients, none was SBS onset in neonates. Pediatric patients with SBS could achieve favorable long-term survival and enteral autonomy. Different standards of SBS classification such as the age of disease onset, PN duration, and anatomic types of short bowel did not impact the overall mortality of pediatric SBS. Prolonged PN duration positively correlated with the age of disease onset and the incidence of CRBI. Patients with the complete continuity of intestinal tract suffered less from CRBI.

Vancomycin-lock therapy for prevention of catheter-related bloodstream infection in very low body weight infants

BackgroundThis study was to evaluate the effectiveness and safety of vancomycin- lock therapy for the prevention of catheter-related bloodstream infection (CRBSI) in very low body weight (VLBW) preterm infant patients.MethodsOne hundred and thirty-seven cases of VLBW preterm infants who retained peripherally inserted central catheters (PICCs) were retrospectively reviewed, including 68 treating with heparin plus vancomycin (vancomycin-lock group) and 69 with heparin only (control group). The incidence of CRBSI, related pathogenic bacteria, adverse events during the treatment, complications, antibiotic exposure, PICC usage time, hospital stay, etc. were compared between the above two groups.ResultsThe incidence rate of CRBSI in the vancomycin-lock group (4.4%, 3/68) was significantly less than in the control group (21.7%, 15/69, p = 0.004). Total antibiotic exposure time during the whole observation period was significantly shorter in the group than in the control group (11.2 ± 10.0 vs 23.6 ± 16.1 d; p < 0.001). No hypoglycemia occurred during the locking, and the blood concentrations of vancomycin were not detectable.ConclusionsVancomycin-lock may effectively prevent CRBSI in Chinese VLBW preterm infants and reduce the exposure time of antibiotics, without causing obvious side complications.

Reduction of Tunnelled Haemodialysis Catheters Related Infections by Intervention and Training: A 12 and 18-month Audit

Introduction: Catheter-Related Blood Stream Infections (CRBSI) are an important complication of both non tunnelled and tunnelled haemodialysis catheters, but are often poorly reported for tunnelled haemodialysis-catheters. Aim: To assess the rate, aetiology, and outcomes of CRBSI in patients using a tunnelled catheter at 12-month and 18-month audits at the newly-opened haemodialysis unit having care bundle as a part of routine catheter care. Materials and Methods: A retrospective cross-sectional study involving two audits of CRBSI risk (12-month and 18-month audit) was conducted by the dialysis unit doctors and nursing staff at Medanta Super-Specialty Private Hospital, Indore, Madhya Pradesh, India. Centres for Disease Control (CDC) and prevention core intervention/care bundle for Blood Stream Infections (BSI) reduction were incorporated as a part of routine catheter care. The 12-month (May 2018 to April 2019) and 18-month (May 2018 to November 2019) internal clinical audit were evaluated to assess the impact of care bundle on incidence of CRBSIs. Kidney-Disease- Outcome Quality-Initiative (KDOQI)-2006-criteria was used to define CRBSI. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) version 19.0 software (IBM Corporation, New York, United States). Descriptive and dispersion statistical analysis was done for studied variables. Results: Total patients in 12-months audit with tunnelled haemodialysis catheter were 14 (7 male and 7 female) with median age 64 years and in 18-months audit patient with tunnelled haemodialysis catheter were 18 (11 male and 7 female) with median age 67.5 years. CRBSI incidence was 2.58 per 1000 catheter days at the end of 12-month, with 132 (71.25-202.25) days of median catheter use. Over the 18-month, the incidence of CRBSI dropped to 1.99 per 1000 catheter days. Median period of catheter use increased to 149.5 (83.5-294.5) days. The primary organisms isolated were predominantly gram negative bacterias. Conclusion: Tunnelled catheters may be a reasonable alternative vascular access for haemodialysis in patients with arteriovenous fistula failure as implementation and maintenance of multidisciplinary care bundle reduces CRBSI rate in such patients.

The Incidence and Associated Risk Factors in Central Venous Catheter Associated Infectious Complications within the Autologous Stem Cell Transplant Population of Eastern Health

Background: Central venous catheters (CVCs) carry a risk of infectious complication with associated morbidity and mortality. Hematologic malignancies are a known independent risk factor for these complications. Patients undergoing hematopoietic stem cell transplant (HSCT) are at increased infectious risk with an incidence of 24.7-31.3%. Proposed contributors to this risk are the underlying malignancy, extended neutropenia, and increased requirement for blood products. Existing cohort studies of HSCT patients have been unable to identifying consistent, modifiable risk factors to target with infection prevention and control initiatives. This single-centre retrospective cohort study examines an autologous stem cell transplant population to identifying risk factors associated with CVCs. Objectives:To determine the incidence and incidence rate per 1000 catheter-days within the autologous HSCT program at Eastern HealthTo identify protective and risk factors associated with CVCs in HSCT patientsDescribe the causative agents in CVC infectious complication identified by blood and catheter-tip culture results Methods: Charts of all adult patients with hematologic malignancy who underwent HSCT with CVC placement at Eastern Health between January 1, 2014 and March 1, 2020 were examined to determine which patients experienced any of a catheter-related bloodstream, tunneled-line or exit site infectious complication as defined by the Public Health Agency of Canada's surveillance definitions. Risk factors assessed included patient factors (age, malignancy, history of bacteremia, fungemia or radiation therapy), immunosuppressive factors (lines of chemotherapy, total 90 day corticosteroid burden, erythropoietin use, days to polymorphonuclear cells &amp;gt;500/µL), and CVC factors (line type, insertion site, antibiotic prophylaxis, heparin impregnation, training level of radiologist, days indwelling, thrombotic complication. Additional data captured included 90-day mortality, whether the CVC was terminated and the causative organism identified by blood or catheter-tip culture. Preliminary Results: The incidence of total infectious complications was 56.2% with an incidence of catheter-related bloodstream infection (CR-BSI) of 22.9%. The incidence rate for total infectious complications was 6.51 per 1000-catheter days, with a CR-BSI infectious rate of 2.65. Both incidence and incidence rate were below results found in other centres. In univariate analysis found single-line of chemotherapy (HR 0.114, p=0.001), use of Permacath (HR 0.03, p=0.002), right internal jugular placement (HR 0.048, p=0.006) to be protective for infectious complication. Multivariate analysis identified a history of bacteremia (OR 763.1, p=0.039) and total days CVC indwelling (OR 0.94, p=0.011) to be associated with CVC infectious complication. Conclusion: Modifiable risk factors associated with CVC infectious complication are choice of device and placement site. Risk factors such as multiple lines of previous chemotherapy or history of bloodstream infection signal need to increased observation for infection. Disclosures No relevant conflicts of interest to declare.

The Actual Epidemiological Effectiveness of Assessing and Improving the System for Ensuring the Epidemiological Safety of Medical Care for Catheterized Patients

The basis of optimized conventional system of surveillance and control for catheter-related bloodstream infections (CRBI) was priority in detection and risk assessment an infectious complication of puncture catheterization that substantially justified with inclusion of two main components as an addition to the existing system: monitoring of puncture catheterization, which allows to obtain and analyze data on risk factors for infections associated with the catheterization procedure and subsequent manipulations of the device, standardize approaches to working with a venous catheter and improve the diagnosis of CRBI; assessment of ensuring the epidemiological safety of medical care for catheterized patients. Epidemiological efficiency risk-based surveillance, primarily determined to reduce the incidence of CRBI by 1.8 times compared to initially defined real incidence: 12.5‰ (95% CI — CI 11,8–13 2) vs 22.8‰ (95% CI 21,1–24,5) catheterized patients, p=0.0001.

Chlorhexidine Dressings to Prevent Catheter-Related Bloodstream Infections: A Systematic Literature Review and Meta-analysis

Background: Catheter-related bloodstream infections (CRBSIs) are associated with significant morbidity and mortality. We aimed to determine the effectiveness of chlorhexidine (CHG) dressings in preventing incident CRBSI in different settings and types of catheters. Methods: We searched PubMed, Cochrane Library, CINAHL, Embase, and ClinicalTrials.gov through March 2019 for studies with the following inclusion criteria: (1) population consisted of patients requiring short or long-term catheters; (2) CHG dressing was used in the intervention group and a nonantimicrobial impregnated dressing was used in the control group; (3) CRBSI was reported as an outcome. Randomized controlled trials (RCTs) and quasi-experimental studies were included. We used a random-effect models to obtain pooled OR estimates. Heterogeneity was evaluated with I 2 test and the Cochran Q statistic. Results: The review included 21 studies (17 RCTs). The use of CHG dressings was associated with a lower incidence of CRBSI (pooled RR, 0.63; 95% CI, 0.53–0.76). There was no evidence of publication bias. In stratified analyses, CHG dressing reduced CRBSI in ICU adult patients (9 studies, pRR, 0.52; 95% CI, 0.38–0.72) and adults with oncohematological disease (3 studies, pRR, 0.53; 95% CI, 0.35–0.81) but not in neonates and pediatric populations (6 studies, pRR, 0.90; 95% CI, 0.57–1.40). When stratified by type of catheter, CHG dressing remained protective against CRBSI in short-term venous catheters (11 studies, pRR, 0.65; 95% CI, 0.48–0.88) but not in long-term catheters (3 studies, pRR, 0.76:; 95% CI, 0.19–3.06). Other subgroup analyses are shown in Table 1. Conclusions: CHG dressings reduce the incidence of CRBSI, particularly in adult ICU patients and adults with an onco-hematological disease. Future studies need to evaluate the benefit of CHG in non-ICU settings, in neonates and pediatric populations, and in long-term catheters.Funding: NoneDisclosures: None

Catheter-related bloodstream infections in a nephrology unit: Analysis of patient- and catheter-associated risk factors.

Central venous catheter use is rising in chronic and acute hemodialysis. Catheter-related bloodstream infections are a major complication of central venous catheter use. This article examines clinical factors associated with catheter-related bloodstream infections incidence. In this retrospective, single-center study, 413 patients undergoing extracorporeal treatments between 1 February 2014 and 31 January 2017 with 560 central venous catheters were recruited. Clinical parameters, such as gender, age, kidney disease status, diabetes, immunosuppression, and vintage dialysis, were collected at study entry. An incidence rate ratio (95% confidence interval) was calculated to assess the association between catheter-related bloodstream infections incidence rate and each clinical variable/central venous catheter type. Significant associations at the univariate analyses were investigated with multivariate Cox models. During a cumulative time of 66,686 catheter-days, 54 catheter-related bloodstream infections (incidence rate: 0.81) events occurred. Gram negative bacteria were more frequent in patients with age < 80 years (16 (36%) vs. 0, p = 0.02). At the univariate analyses, male sex (incidence rate ratio: 1.9 (1.1-3.5), p = 0.03), age < 80 years (incidence rate ratio: 2.4 (1.1-5.5), p = 0.016) and acute kidney injury (incidence rate ratio: 5.6 (3.1-10), p < 0.0001) were associated with higher catheter-related bloodstream infections incidence rate. Compared with tunneled jugular central venous catheter, higher catheter-related bloodstream infections incidence rate was associated with non-tunneled jugular (incidence rate ratio: 6.45 (2.99-13.56), p < 0.0001) and non-tunneled femoral (incidence rate ratio: 12.90 (5.87-27.61), p < 0.0001) central venous catheter use; tunneled femoral central venous catheter was associated with higher non-significant incidence rate (incidence rate ratio: 2.45 (0.93-5.85), p = 0.07). The multivariate analyses showed that acute kidney injury (hazard ratio: 3.03 (1.38-6.67), p = 0.006), non-tunneled (hazard ratio: 3.11 (1.30-7.41), p = 0.01) and femoral (hazard ratio: 2.63 (1.36-5.07), p = 0.004) central venous catheter were associated with higher catheter-related bloodstream infections incidence rate. Central venous catheter characteristics and acute kidney injury are independently associated with higher catheter-related bloodstream infections rate.

Catheter-Related Bloodstream Infection for End Stage Renal Disease Patients -Evaluation in the Era of Low Budget National Health Insurance Coverage in Indonesia-

Introduction: The use of central venous catheter (CVC) plays an essential role in patient care. The catheter-related bloodstream infection (CRBSI) is one of complications and associated with morbidity and mortality. In Indonesia, the national health coverage for single CVC procedure claim is only US$ 197-286. The aim of this study is to evaluate CRBSI number after subclavian and femoral non-tunnelled catheter insertion for urgent haemodialysis access. Method: A retrospective study with the simple consecutive sampling was conducted. The inclusion criteria were adult and end stage renal disease (ESRD) patients required urgent haemodialysis access with infection on the site of insertion on the subclavian or femoral access. Exclusion criteria were artery catheter placement, pacing catheter, and another sources of previously infection was defined. Patients were divided into subclavian and femoral access group then we evaluate them retrospectively based on medical record data. Results: Forty patients with 20 patients were subclavian inserted, and rest were femoral inserted. Infections rate was 7.84%. Demographic showed 55% was male (22/40) &amp; age 51.8±14.3 years. Catheter duration in subclavian and femoral group were 47.7±34.2 and 36.7±18.4 days, respectively. Hospital stays in subclavian and femoral group were 9.9±6.4 and 9.3±7.2 days, respectively. From SIRS criteria, in subclavian group showed the heart rate, respiratory rate, body temperature and white blood cell (WBC) count were 90.1±7.8 x/min, 21.1±2.6 x/min, 37.4±0.8 °C, 15.5.0±7.0 *103/μL, respectively. For femoral group were 86.8±10.5 x/min, 21.6±4.0 x/min, 36.9±0.6 °C, 14.9±8.4 *103/μL, respectively. The p- values of them were 0.273, 0.612, 0.041, and 0.793 respectively. Eighty percent in subclavian group was first insertion, and for femoral group was 50% (p=0.047). In subclavian group was 10% (2/20) patients had more than three times insertion and femoral group was 25% (5/20) (p=0.225). Creatinine and ureum level in subclavian group were 9.4±5.8 and 155.5±83.6 mg/dL and for femoral group were 11.4±6.2 and 133.6±50.3 mg/dL (p=0.298 and 0.322, respectively). A 62.5% of all patients (25/40) was treated with third generation cephalosporin. The p-value for amount of intravenous antibiotic (single, double, triple) between subclavian and femoral group was 0.352. There was no blood culture taken for all patients. Sepsis and death as complication was 10% and 5% from all patients, respectively. Conclusion: Prolonged use of central venous catheter more than 2 weeks and recurrent procedure were the cause of increasing incidence of CRBSI. Ultrasound guiding is needed to decrease complication. In a low budget system for national health insurance in Indonesia, a good strategy (pre-ESRD arteriovenous fistula, internal jugular vein access, nosocomial infection prevention, and rational antibiotic usage with a rational blood culture) need to be developed to prevent the infection of CRBSI.

Comparative Complication Rates of 854 Central Venous Access Devices for Home Parenteral Nutrition in Cancer Patients: A Prospective Study of Over 169,000 Catheter-Days.

Whether peripherally inserted central catheters (PICCs) are appropriate as safe and durable venous access devices (VADs) is still controversial. The aim of this 7-year, prospective cohort study was to compare the incidence rate differences of catheter-related complications (CRCs) among 4 types of central VADs in cancer patients receiving home parenteral nutrition (HPN). We enrolled all adult cancer outpatients who were candidates for HPN and who had a central VAD inserted during the study period, focusing on the incidence rate of CRCs. We evaluated 854 central VADs (401 PICCs, 137 nontunneled centrally inserted central catheters [CICCs], 118 tunneled-cuffed CICCs, and 198 ports) in 761 patients, for a total of 169,116 catheter-days. Overall, the rate of total CRCs was 1.08/1000 catheter-days. The incidence of catheter-related bloodstream infections was low (0.29/1000), particularly for PICCs (0.08/1000; P < .001 vs tunneled-cuffed CICCs) and for ports (0.21/1000; P < .019 vs tunneled-cuffed CICCs). The rates of mechanical complications (0.58/1000) and of catheter-related symptomatic thrombosis (0.09/1000) were low and similar for PICCs, tunneled-cuffed CICCs, and ports. In terms of duration and removal rate due to complications, PICCs were like tunneled-cuffed CICCs and ports. Altogether, PICCs had fewer total complications than tunneled-cuffed CICCs (P < .001), there was no difference in total complications between PICCs and ports. PICCs had significantly better outcomes than tunneled-cuffed CICCs and were safe and durable as ports. Our extensive, long-term study suggests that PICCs can be successfully used as safe and long-lasting VADs for HPN in cancer patients.

Impact of duration of antibiotic therapy in central venous catheter-related bloodstream infection due to Gram-negative bacilli.

A progressive increase in the incidence of catheter-related bloodstream infection (CRBSI) due to Gram-negative bacilli (GNB) has been reported. Current guidelines recommend antibiotic treatment for at least 7-14 days, although the supporting evidence is limited. We performed a retrospective single-centre study including all patients with a definite diagnosis of GNB CRBSI from January 2012 to October 2018 in which the central venous catheter (CVC) was removed. The occurrence of therapeutic failure [clinical failure (persistence of symptoms and laboratory signs of infection), microbiological failure (persistent bacteraemia or relapse) and/or all-cause 30 day mortality] was compared between episodes receiving short [≤7 days (SC)] or long courses [>7 days (LC)] of appropriate antibiotic therapy following CVC removal. We included 54 GNB CRBSI episodes with an overall rate of therapeutic failure of 27.8% (15/54). Episodes receiving SC therapy were more frequently due to MDR GNB [60.9% (14/23) versus 34.5% (10/29); P = 0.058] and had higher Pitt scores [median (IQR) 1 (0-4) versus 0 (0-2); P = 0.086]. There were no significant differences in the rate of therapeutic failure between episodes treated with SC or LC therapy [30.4% (7/23) versus 27.6% (8/29); OR 1.15; 95% CI 0.34-3.83; P = 0.822]. The use of SCs was not associated with increased odds of therapeutic failure in any of the exploratory models performed. The administration of appropriate antibiotic therapy for ≤7 days may be as safe and effective as longer courses in episodes of GNB CRBSI once the CVC has been removed.

Practice of nosocomial infection management in burn department based on the American hospital evaluation standard of the Joint Commission International

Objective: To explore the role of continuous quality improvement measures based on the American hospital evaluation standard of the Joint Commission International (JCI) in prevention and control of nosocomial infection in Burn Department of the Second Affiliated Hospital of Zhejiang University School of Medicine (hereinafter referred to as the author' s department). Methods: From 2013 to 2018, based on 11 JCI standards related to infection prevention and control and the current situation of the author' s department, more than 50 doctors, nurses, and nursing assistants from the author' s department participated in continuous improvement of the three-level management system of nosocomial infection in the author' s department, focusing on implementing of management of patient with multidrug resistant bacteria infection, optimizing the infection control management of instrument and cloth, and implementing target management on 5 indicators such as hand hygiene implementation rate, and carrying out inspection, quality management, and improvement on 11 items of prevention and control of nosocomial infection. The implementation rate of hand hygiene from 2013 to 2018 and the accuracy rate of hand hygiene from 2016 to 2018 of medical staff in the author' s department, and incidences of catheter-related bloodstream infection (CRBSI) of central venous, catheter-associated urinary tract infection (CAUTI), and ventilator associated pneumonia (VAP) of burn intensive care unit in the author's department from 2013 to 2018 were monitored.The following 7 indicators were monitored from 2013 to 2018, including false negative rate of nosocomial infection, incidence of hyperglycemia during intensive insulin treatment for severely burned patients, the implementation rate of CRBSI preventive measures, the specification rate of surface fixation of indwelling catheter, the implementation rate of VAP preventive measures, the accuracy rate of bed temperature during the use of suspended bed, and the implementation rate of hand hygiene of standardized training medical staff in the author' s department before and after improvement. Data were statistically analyzed with chi-square test. Results: The implementation rate of hand hygiene of medical staff in the author' s department was 88.0%-89.5% from 2013 to 2018, the correct rate of hand hygiene of medical staff in the author' s department was 95.10%-97.35%, and both reached the target values. The incidences of CRBSI in 2015, VAP in 2017, and CAUTI in 2013, 2014, and 2017 of burn intensive care unit failed to reach the respective target value and reached the respective target value after quality improvement, and the above-mentioned 3 indicators reached the respective target value in other years. From 2013 to 2018, the false negative rate of nosocomial infection and the incidence of hyperglycemia during intensive insulin treatment of severely burned patients in the author' s department after improvement were significantly lower than those before improvement (χ(2)=24.50, 4.74, P<0.05 or P<0.01), the implementation rate of CRBSI preventive measures, the specification rate of surface fixation of indwelling catheter, the implementation rate of VAP preventive measures, and the accuracy rate of bed temperature during the use of suspended bed after improvement in the author' s department were significantly higher than those before improvement (χ(2)=13.78, 6.50, 20.37, 13.92, P<0.05 or P<0.01), and the implementation rate of hand hygiene of standardized training medical staff in the author' s department after improvement was similar to that before improvement (χ(2)=1.71, P>0.05). Conclusions: The introduction of JCI standard can improve the implementation rate and accuracy rate of hand hygiene of medical staff in burn department, reduce the incidences of CRBSI, CAUTI, and VAP, and improve the effect of prevention and control of nosocomial infection in burn department.
