Knowledge and compliance to prevention of central line-associated blood stream infections among registered nurses in Jordan.

Central line-associated bloods tream infections (CLABSIs) are among the most common healthcare-associated infections (HAIs). To assess the rates of CLABSIs and to investigate predictors of knowledge and compliance of registered nurses to central venous catheters (CVCs) maintenance care bundle in intensive care units (ICUs). A cross-sectional correlational design was used. A convenient sample of 114 registered nurses was selected from three hospitals in Jordan. Nurses' knowledge and compliance were measured by previously established measures and an observational checklist developed according to the Center for Disease Control and Prevention (CDC). The rate of CLABSI was the lowest in the hospital that applies the CVC bundle of care. Nurses' knowledge about CLABSI prevention practices was significantly correlated with their compliance to CVCs maintenance care bundle. Nurses' knowledge differed bytheirage, income, experience in ICU, and nurse-to-patient ratio, and in multiple regressions, age was the single predictor of knowledge of CLABSI prevention. Significant differences were also found in nurses' compliance to the CVC care bundle according to the hospital and nurse-to-patient ratio. The nurse-to-patient ratio was the single significant predictor, and it attenuated the effect of age and income on nurse's compliance to the CVC care bundle. This study indicated the need to expand the application of the CVC maintenance care bundle in hospitals. Programs that target promoting nurses' knowledge about CLABSI prevention and compliance to CVC care need to consider some factors, such as nurses' age and the circumstances of their work (nurse-to-patient ratio).

The Impact of Interventions to Prevent Neonatal Healthcare-associated Infections in Low- and Middle-income Countries: A Systematic Review.

Background:Clinically suspected and laboratory-confirmed bloodstream infections are frequent causes of morbidity and mortality during neonatal care. The most effective infection prevention and control interventions for neonates in low- and middle-income countries (LMIC) are unknown.Aim:To identify effective interventions in the prevention of hospital-acquired bloodstream infections in LMIC neonatal units.Methods:Medline, PUBMED, the Cochrane Database of Systematic Reviews, EMBASE and PsychInfo (January 2003 to October 2020) were searched to identify studies reporting single or bundled interventions for prevention of bloodstream infections in LMIC neonatal units.Results:Our initial search identified 5206 articles; following application of filters, 27 publications met the inclusion and Integrated Quality Criteria for the Review of Multiple Study Designs assessment criteria and were summarized in the final analysis. No studies were carried out in low-income countries, only 1 in Sub-Saharan Africa and just 2 in multiple countries. Of the 18 single-intervention studies, most targeted skin (n = 4) and gastrointestinal mucosal integrity (n = 5). Whereas emollient therapy and lactoferrin achieved significant reductions in proven neonatal infection, glutamine and mixed probiotics showed no benefit. Chlorhexidine gluconate for cord care and kangaroo mother care reduced infection in individual single-center studies. Of the 9 studies evaluating bundles, most focused on prevention of device-associated infections and achieved significant reductions in catheter- and ventilator-associated infections.Conclusions:There is a limited evidence base for the effectiveness of infection prevention and control interventions in LMIC neonatal units; bundled interventions targeting device-associated infections were most effective. More multisite studies with robust study designs are needed to inform infection prevention and control intervention strategies in low-resource neonatal units.

Prevention of central line-associated bloodstream infections: ICU nurses' knowledge and barriers.

Central line-associated bloodstream infections (CLABSI) have been a significant challenge in care, increasing healthcare costs and leading to adverse outcomes, including mortality. The present study aimed to assess the knowledge of intensive care unit (ICU) nurses on the prevention of CLABSI and the implementation barriers of evidence-based guidelines in practice. A cross-sectional study. Data were collected from adult, paediatric, and neonatal ICU nurses working in seven hospitals in Iran, using census sampling from April to July 2020. A number 209 out of 220 ICU nurses participated in the present study (response rate of 95%). The median score of knowledge of ICU nurses towards the prevention of CLABSI was 3.00 out of 11. 50.72% of ICU nurses had insufficient knowledge. The most critical implementation barriers of evidence-based guidelines were high workload, shortage of necessary equipment, and lack of CLABSI prevention workshops. Overall, the knowledge of ICU nurses towards the prevention of CLABSI was insufficient. Study findings suggest that the knowledge of ICU nurses may be improved by reducing the workload, increasing the number of nursing staff in the ICU, having an adequate supply of equipment needed to ensure safe practice in the ICU, and providing regular related educational workshops for nurses working in the ICU. The present study's findings suggest that regular training programs should be developed to improve the knowledge of ICU nurses in the care and prevention of CLABSI. Nursing policymakers and managers need to identify and address implementation barriers of evidence-based guidelines to improve nursing, such as high workload, shortage of necessary equipment, and lack of CLABSI prevention workshops.

Central Line–Associated Bloodstream Infections and Advanced Practice Providers: Identifying Opportunities for Prevention Efforts

Central venous catheters can be a vital part of patient care in the hospital setting but are at high risk of infection. Central line–associated bloodstream infections pose a high risk of morbidity, mortality, and increased hospital costs. The purpose of this project is to assess the practices and learning needs of advanced practice providers (nurse practitioners and physician assistants) in the provision of evidence-based care to patients with central venous catheters in the hospital setting. This can guide further educational initiatives for central line–associated bloodstream infection prevention.

The role of simulation-based training in healthcare-associated infection (HAI) prevention.

To perform a review of the literature on the role of simulation-based training (SBT) in healthcare-associated infection (HAI) prevention and to highlight the importance of SBT as an educational tool in infection prevention. We reviewed English language publications from PubMed to select original articles that utilized SBT as the primary mode of education for infection prevention efforts in acute-care hospitals. Overall, 27 publications utilized SBT as primary mode of education for HAI prevention in acute-care hospitals. Training included the following: hand hygiene in 3 studies (11%), standard precaution in 1 study (4%), disaster preparedness in 4 studies (15%), central-line-associated blood stream infection (CLABSI) prevention in 14 studies (52%), catheter-associated urinary tract infection (CAUTI) prevention in 2 studies (7%), surgical site infection prevention in 2 studies (7%), and ventilatory associated pneumonia prevention in 1 study (4%). SBT improved learner's sense of competence and confidence, increased knowledge and compliance in infection prevention measures, decreased HAI rates, and reduced healthcare costs. SBT can function as a teaching tool in day-to-day infection prevention efforts as well as in disaster preparedness. SBT is underutilized in infection prevention but can serve as a crucial educational tool.

Adherence to central venous catheter maintenance bundle in an intensive care unit.

To check adherence to the Central Venous Catheter maintenance bundle in an Intensive Care Unit, after an educational intervention to the professionals who provide care to patients using this catheter. Descriptive-exploratory study, carried out in two stages: stage 1 - educational intervention and stage 2 - verification/observation of adherence. Data were organized in the Microsoft Excel® and analyzed through the Stata®. Sixty three workers participated in stage 1 and 44 in stage 2. The sample consisted of 64 observation opportunities. Among the domains observed, the recording of indication of permanence had an 8% compliance rate; aseptic technique in catheter handling, 3%; maintenance of the infusion system, 15%; and care with the central venous catheter dressing, 17%. The domains represent unwanted care according to the Positivity Index for assessing the quality of care. The findings show the need for discussions, training, and investments in constant strategies for the prevention of primary bloodstream infections related to the central venous catheter.

Developing Information Model of Central Line-Associated Bloodstream Infection (CLABSI) Prevention.

CLABSIs are one of the most lethal and costly types of healthcare associated infections (HAIs). Regulatory organizations have mandated hospitals to submit monthly surveillance reports. However, there is an inaccuracy of presenting this report because of the lack of data standardization. This descriptive qualitative study aimed to develop a CLABSI prevention Information Model (IM) so the CLABSI prevention guidelines can be incorporated into structured nursing documentations. The flowsheet metadata stored in the Clinical Decision Repository was analyzed using an advanced analytics tool. The CLABSI prevention flowsheet data were mapped to 25 concepts, 45 data attributes and over 200 data value sets after organizing hierarchical structures. Seven domains of CLABSI prevention were identified in a CLABSI prevention IM. It would provide tangible benefits to create a practice reminder of the high risk for CLABSIs based on the nursing flowsheet data sets and multidisciplinary Electronic Health Record (EHR).

Efficacy and safety of 1.5% aqueous olanexidine gluconate antiseptic solution compared to 1% alcoholic chlorhexidine for the prevention of intravenous catheter-related infections (Apollo study): a protocol for a randomised controlled trial

IntroductionChlorhexidine alcohol (1.0%–2.0%) is currently recommended as a skin disinfectant to be used prior to catheterisation for preventing catheter-related infections. However, chlorhexidine alcohol has various side effects and has little antibacterial effect on methicillin-resistant Staphylococcus aureus (MRSA). Therefore, MRSA remains a concern for catheter-related bloodstream infection (CRBSI) prevention. Olanedine, containing 1.5% olanexidine gluconate in aqueous solution, was developed in Japan in 2015 and is structurally similar to chlorhexidine. Olanexine has been used as a disinfectant against various gram-positive and gram-negative bacteria and MRSA. This study aims to compare the efficacy of 1.5% aqueous olanexidine gluconate and 1% chlorhexidine alcohol as skin antiseptics for the prevention of catheter-related infections.Methods and analysisThis Apollo study is an open-label, multicentre, non-inferiority, two-arm, parallel-group, randomised controlled trial conducted at 21 intensive care units (ICUs) and high-care units (HCUs) in Japan. All patients scheduled to be admitted to the ICU or HCU of a facility participating in this study, who require central venous catheter insertion are eligible. Eligible patients will be assigned to either the 1.5% aqueous olanexidine gluconate or 1% chlorhexidine alcohol group by randomisation in a ratio of 1:1 with stratification by centres. The antibacterial agents are to be used as a skin disinfectant before and during catheter placement. The primary endpoint is the proportion of catheter-related infections, defined as a composite of catheter-related sepsis without bacteraemia and CRBSI. A total of 1980 patients will be included in this study.Ethics and disseminationThis clinical trial was approved by the Institutional Review Board of Jichi Medical University and the ethics committees of the participating institutions. The study results will be disseminated through conferences, peer-reviewed publications and meetings with interested parties.Trial registration numberUniversity hospital Medical Information Network (registration ID: UMIN000042343). This registration includes all items in the WHO Trial Registration Data Set.Protocol versionThis protocol corresponds to the original protocol version 5.

Does the Midline Peripheral Intravenous Catheter Have a Place in Critical Care?

The goals of infusion therapy are to preserve vascular health and safely deliver needed treatment. Achieving these goals is challenging in critical care because of the complexity of the treatment required. Daily justification of retaining an existing central venous catheter also creates urgency to change to a peripheral vascular access device. The midline catheter has had a resurgence in use because of the need for a long-term peripheral vascular access device not linked to central catheter-associated bloodstream infection risk. To review the characteristics of midline catheters, the benefits and risks of midline catheters, and current evidence regarding midline catheter use in critical care. Research related to midline catheters has greatly expanded the body of knowledge regarding vascular access device selection and midline catheter use. Although the quality and results of research on vascular access devices vary widely, a more accurate safety profile is emerging to illustrate how midline catheter use can support the goals of infusion therapy. Optimizing vascular access device selection requires recognition that every vascular access device can cause patient harm. Although the midline catheter appears to fill an important niche in infusion therapy, use of the midline catheter should be carefully evaluated. Midline catheters should not be used as a catheter-associated bloodstream infection prevention strategy, should be inserted to administer peripherally compatible solutions, and should be considered for short-term continuous vesicant therapy only in emergent situations until more definitive vascular access can be achieved.

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.

A Prospective Study of Family Engagement for Prevention of Central Line-associated Blood Stream Infections.

We sought to determine if a family-centered care (FCC) handout intervention designed to encourage family engagement (FE) in the prevention of central line-associated bloodstream infections (CLABSIs) would alter parental perceptions of FCC and improve staff compliance with CLABSI bundle components. A prospective quasiexperimental study of 121 legal guardians of children with a central venous catheter (CVC) admitted to the pediatric intensive care unit (PICU). Baseline (n = 59) and intervention (n = 62) groups of parents completed an 18-question online survey assessing basic CLABSI care practices and FCC principles. The intervention group received an FE handout before completing the survey with information about CLABSI prevention practices designed to encourage active participation in their child's CVC care. Independent sample t-tests found significant improvements in the intervention parents responses compared to the baseline group (no handout) on survey items assessing CLABSI knowledge (P < 0.001) and on parental perceptions of FCC in the domains of dignity and respect, information sharing, participation, and partnership (all with a P < 0.001). An improvement was observed in staff CLABSI maintenance bundle compliance in the postintervention period, increasing from 89% to 94%. Educating parents on CLABSI prevention strategies and encouraging family participation in CVC care was associated with improved parental perceptions of participation in their child's care, medical team's listening, attention, honesty, and explanation of treatment plans and was associated with an increase in staff compliance with CLABSI maintenance bundle practices.

Prevention of Central Line-Associated Bloodstream Infections Through Educational Interventions in Adult Intensive Care Units: A Systematic Review.

Central line-associated bloodstream infections (CLABSIs) represent a severe systemic threat to patients admitted in ICUs and contribute to increased mortality, prolonged length of stay in ICUs, and increased costs. The majority of CLABSIs are preventable. The current systematic review aimed to investigate the effectiveness of educational methods on CLABSI rates in adult ICUs.A systematic literature search was conducted using the electronic databases of Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL) Plus, and Cochrane Database of Systematic Reviews for studies published from the beginning of 1995 to March 2020. The terms used for the search were as follows: central venous catheters, infection, central line-associated bloodstream infections, intensive care unit, and education intervention in all possible combinations and using the word ‘and’ between them. Data were extracted independently and crosschecked by two authors using a standard data collection form. The quality of the studies included in the review was assessed using the Methodological Index for Non-randomized Studies (MINORS).The current systematic review included 27 interventional studies of central line insertion or maintenance or both in adult ICU settings with documentation of the CLABSI incidence expressed per 1,000 catheter days. A large deviation between the length of time and type of educational interventions was found.Statistical significance was found in all studies (except one) in terms of CLABSI reduction despite the large variation of the length or the type of the educational intervention. Continuing education on infection prevention may be necessary to maintain the post-intervention results and improve clinical outcomes.

Clinical utility of oral management in allogeneic hematopoietic stem cell transplantation recipients: microbiological evidence based on molecular analysis of oral bacteria.

This study aimed to clarify the clinical utility of oral management to prevent bloodstream infections by oral bacteria microbiologically in patients undergoing allogeneic hematopoietic stem cell transplantation (ASCT). Ten consecutive patients with hematological malignancies undergoing ASCT were enrolled in this study. We implemented dental treatments before transplantation, if required, and carried out oral hygiene instructions and oral management every other day after transplantation. Molecular analysis of bacterial DNA for seven oral species using a polymerase chain reaction (PCR) assay was performed for oral samples and peripheral blood once a week for 3weeks after transplantation. Periodontitis was found in all 10 patients (mild grade in 3 and middle grade in 7) for whom basic periodontal therapy was conducted. Necessary dental procedures, including tooth extraction were performed in 5 patients. After transplantation, oral mucositis occurred in 10 patients (grade 1 in 3, grade 2 in 2, and grade 3 in 5) for whom oral hygiene instruction and oral care were continued every other day. PCR-identified three to six bacterial species in oral samples from nine patients, but none in peripheral blood from any patient during the observation period. Our study suggests that oral management could prevent bloodstream infections by oral bacteria in ASCT recipients despite the existence of periodontitis or oral mucositis. Its utility was confirmed by microbiological evidence based on molecular data.

Antibiotic sensitivity/resistance pattern of hospital acquired blood stream infection in children cancer patients: A retrospective study.

The literature shows a growing emphasis on understanding the local patterns of antimicrobial resistance (AMR). We aimed to evaluate the spectrum of local microorganisms that cause bloodstream infections (BSI) and their AMR patterns in an Egyptian institution treating children with cancer. We conducted a single-centre, retrospective, study on children with confirmed primary, hospital-acquired, BSIs over one year. The microbiological examination of blood samples was done according to the Clinical and Laboratory Standards Institute. The antibiotic sensitivity test was done using VITEK® 2 system. We retrieved the data of 607 children with a median age of 5 (0.25-18) years old. The most encountered diagnosis was acute lymphoblastic leukaemia (40%). Most identified microorganisms were gram-negative bacilli, mainly Escherichia coli (27.8%), followed by Klebsiella pneumoniae (12.2%). Gram-negative bacilli showed high resistance to piperacillin/tazobactam, levofloxacin, and meropenem. The lowest resistance rates for Gram-negative bacilli isolates were noted for colistin and tigecycline. Similarly, the gram-positive cocci showed high resistance to ampicillin/sulbactam, cefoxitin, and clindamycin; and low resistance regarding vancomycin and linezolid. Resistance proportions (pattern) were similar to those reported in other countries with a higher distribution of E coliand a growing resistance to levofloxacin. Further investigation of the predisposing factors and the development of more effective strategies for the prevention of BSI should be a significant public health priority.

Neonatal bloodstream infections.

Neonatal bloodstream infections (BSI) are a major contributor to morbidity and mortality within neonatal intensive care units. BSI, including central line-associated BSI, have decreased over the past 15 years but remain common in extremely preterm infants. The purpose of this review is to highlight recent advances in the causes, diagnosis, management, and prevention of neonatal BSI. Continued quality improvement efforts and bundles have reduced BSI incidence, and novel approaches are highlighted. An update of emerging pathogens as well as traditional pathogens with novel antimicrobial resistance, which are an increasingly common cause of neonatal BSI, is included. Finally, current and future investigations into serum or noninvasive biomarkers for neonatal BSI are reviewed. Neonatal BSIs continue to decrease due to enhanced infection control and prevention techniques. However, many challenges remain, including emerging bacterial and fungal resistance and the continued need for novel diagnostics that hasten time to pathogen identification and effective treatment. This review of the past 18 months highlights the rapid changes in this area. Ongoing efforts to reduce the morbidity and mortality caused by neonatal BSI must remain a priority.
