Centers for Disease Control and Prevention guidelines for preventing central venous catheter-related infection: Results of a knowledge test among 3405 European intensive care nurses*:

Development of best evidence-based practice protocols for central venous catheter placement and maintenance to reduce CLABSI

Although evidence-based interventions can reduce the incidence of central line-associated bloodstream infection (CLABSI), there is a large gap between evidence-based interventions and the actual practice of central venous catheter (CVC) care. Evidence-based interventions are needed to reduce the incidence of CLABSI in intensive care units (ICU) in China. Professional association, guidelines, and database websites were searched for data relevant to CLABSI in the adult ICUs from inception to February 2020. Checklists were developed for both CVC placement and maintenance. Based on the Integrated Promoting Action on Research Implementation in Health Services framework, a questionnaire collected the cognition and practice of ICU nursing and medical staff on the CLABSI evidence-based prevention guidelines. From January 2018 to December 2021, ICU CLABSI rates were collected monthly. Ten clinical guidelines were included after the screening and evaluation process and used to develop the best evidence-based protocols for CVC placement and maintenance. The CLABSI rates in 2018, 2019, and 2020 were 2.98‰ (9/3021), 1.83‰ (6/3276), and 1.69‰ (4/2364), respectively. Notably, the CLABSI rate in 2021 was 0.38‰ (1/2607). In other words, the ICU CLABSI rate decreased from 1.69‰ to 0.38‰ after implementation of the new protocols. Additionally, our data suggested that the use of ultrasound-guidance for catheter insertion, chlorhexidine body wash, and the use of a checklist for CVC placement and maintenance were important measures for reducing the CLABSI rate. The evidence-based processes developed for CVC placement and maintenance were effective at reducing the CLABSI rate in the ICU.

Effects of the care given to intensive care patients using an evidence model on the prevention of central line-associated bloodstream infections

It is important to put evidence-based guidelines into practice in the prevention of central line-associated bloodstream infections in intensive care patients. In contrast to expensive and complex interventions, a care bundle that includes easy-to-implement and low-cost interventions improves clinical outcomes. The compliance of intensive care nurses with guidelines is of great importance in achieving these results. The Translating Evidence into Practice Model provides guidance in how to implement the necessary guidelines. This quasi-experimental study used a post-test control group design in nonequivalent groups and was conducted in the anesthesia intensive care unit of a tertiary-level training and research hospital. All patients who were hospitalized in the intensive care unit, who had a central line during the study, and who met the inclusion criteria were included in the sample. The care bundle comprised education, and protocols for hand hygiene and the aseptic technique, maximum sterile barrier precautions, central line insertion trolley, and management of nursing care. To analyze the data, the independent samples t-test, the Mann-Whitney U test, chi-square test, dependent samples t-test, rate ratio, and relative risk were used with 95% confidence intervals. The rate of central line-associated bloodstream infections was significantly lower in the intervention group (2.85/1000 central line days) than in the control group (3.35/1000 central line days) (P = 0.042). The number of accesses to the central line by the nurses decreased significantly in the intervention group compared to the control group (P < 0.001). The mean score for the nurses' evidence-based guideline post-education knowledge (70.80 ± 12.26) was significantly higher than that pre-education (48.20 ± 14.66) (P < 0.001). Compliance with the guideline recommendations in central line-related nursing interventions and in the central line insertion process was significantly better in the intervention group than in the control group in many interventions (P < 0.05). The mean score for the nurses' attitude towards evidence-based nursing increased significantly over time (59.87 ± 7.23 at the 0th month; 63.79 ± 7.24 at the 6th month) (P < 0.001). Nursing care given by implementing the central line care bundle with the Translating Evidence into Practice Model affected the measures. Thanks to the implementation of the care bundle, the rate of infections and the number of accesses to the central line decreased, while the critical care nurses' knowledge of evidence-based guidelines, compliance with the guideline recommendations in central line-related nursing interventions, and attitudes towards evidence-based nursing improved.

Compliance with good practice guidelines for the prevention of vascular access infections: the multi-centre PHYDEL survey in French haemodialysis units

BACKGROUND

French guidelines for the prevention of vascular access infections in a haemodialysis setting were released in 2005. Compliance with these guidelines is currently unknown. The aim of this study was to assess compliance with the guidelines for vascular access infection prevention in French haemodialysis units, and to describe the difficulties reported.

METHODS

A cross-sectional survey was conducted between March and December 2019 in 200 haemodialysis units in France, selected at random. Data were collected via questionnaire, completed by telephone interview with an infection control practitioner. A practice was deemed compliant when >85% of units declared that they always complied with the guidelines.

RESULTS

In total, 103 units (51.5%) agreed to participate. Most practices complied with the guidelines; however, some practices did not reach the 85% compliance threshold for working in pairs when connecting central venous catheter (CVC) lines, performing hand hygiene before disconnecting lines, rinsing antiseptic soap before painting CVC exit site or arteriovenous fistula (AVF) puncture site, allowing antiseptic paint to dry, handling CVC branches with antiseptic impregnated gauze, performing hand hygiene after AVF compression with gloves, wearing protective eyewear when connecting/disconnecting CVC or when puncturing AVF, and wearing a gown when puncturing AVF. The most frequently reported difficulties were understaffing, difficulties with skin preparation because of exit site skin damage, and lack of buttonhole technical expertise.

CONCLUSIONS

Despite good overall compliance, this survey highlights some shortcomings in compliance with infection prevention guidelines, which could be associated with either higher risk of vascular access infection or increased blood-borne virus transmission.

An Interactive E-learning Platform-Based Training to Improve Intensive Care Professionals' Knowledge Regarding Central Venous Catheter-Related Infections

Introduction The presence of a central venous catheter (CVC) leads to a high risk for blood infections, which are associated with increases in morbidity, mortality, and costs. This study aims to assess intensive care unit (ICU) nurses' and physicians' knowledge regarding the Centers for Disease Control and Prevention (CDC) guidelines for preventing CVC-related infections before and after an interactive distance education delivered through the e-learning platform Teleprometheus. Materials and methods The study was conducted among 85 nurses and physicians in Nicosia's General Hospital Intensive Care Unit (NGH-ICU) and high dependency unit (HDU). A validated questionnaire was used to assess nurses' and physicians' knowledge. Results Prior to the online interactive distance education, the mean total knowledge score was x̄ = 4.8 (SD = 2.46), while after, the mean total knowledge score increased to x̄ = 8.9 (SD = 2.38) (p<0.001). ICU physicians had a higher mean total knowledge score (x̄ = 10.20) than ICU nurses (x̄ = 8.75) after the intervention. There was no correlation between years of experience in the ICU and the level of knowledge (r = 0.048). The interactive distance education was positively evaluated by the participants, through a questionnaire, specially designed for this study. Discussion The most important findings were that (a) the level of knowledge of the participants improved with a statistically significant difference after the completion of the e-course, (b) the level of knowledge of the participants, after the completion of the e-course, was much higher from other studies, (c) there was no correlation between the years of experience of ICU health professionals and their level of knowledge, and (d) the interactive distance e-course was positively evaluated and satisfied the participants. Conclusion The current study demonstrates that in high-intensity work environments, such as ICUs, adopting e-learning approaches seems more necessary than ever.

Nursing experiences in antimicrobial optimisation in the intensive care unit: A convergent analysis of a national survey

BACKGROUND

Recent evidence highlights the need for an interdisciplinary approach to antimicrobial stewardship (AMS). Nursing involvement in optimising antimicrobials in the intensive care unit (ICU) remains understudied.

OBJECTIVE

The objective of this study was to explore nurses' perceptions and experiences of antimicrobial optimisation or stewardship in ICUs in Australia.

METHODS

An anonymous web-based survey was deployed nationally in early 2021 through two ICU nursing networks. Associations between survey responses were analysed descriptively and by using nonparametric tests (with statistical significance established at p ≤ 0.05). Free-text survey responses underwent qualitative thematic analysis. Interpretation and reporting of quantitative and qualitative data were integrated.

RESULTS

A total of 226 ICU nurses completed the survey. The majority (197/226; 87%) responded that lack of education limits engagement in AMS. Only 13% (30/226) reported the presence of AMS education and training for nurses in their ICUs. Only about half (108/226; 48%) of the nurses were confident to question prescribers when they considered that the antimicrobial prescribed was unnecessary, with nurses in senior roles more likely to do so than nurses providing bedside care (p < 0.05). Gaps in education (including unfamiliarity with AMS roles), noninclusive antimicrobial discussions, moral distress, and potential workload burden were seen as potential barriers/challenges to engagement.

CONCLUSION

The multifactorial barriers identified that inhibit nurses from performing AMS tasks could be addressed by strengthening interprofessional education at all levels and by applying practical AMS interventions that are inclusive for nursing participation. A purposeful culture change that fosters psychological safety and collaborative practice is paramount to supporting nurses in these roles.

Assessment of Knowledge, Attitude, and Adherence to National Guidelines for Preventing Central Line-Associated Bloodstream Infections Among ICU Nurses of Adult Patients in Jeddah, Saudi Arabia: A Cross-Sectional Survey

BACKGROUND

Central line-associated bloodstream infections (CLABSIs) pose a significant burden on patient outcomes in intensive care units (ICUs). Adherence to evidence-based guidelines for CLABSI prevention is crucial in reducing healthcare-associated infections. This study aimed to assess the knowledge, attitude, and practice adherence to national guidelines for preventing CLABSIs among adult ICU nurses in Ministry of Health (MOH) hospitals in Jeddah, Saudi Arabia.  Methods: This cross-sectional survey included all adult ICU nurses with a minimum of one year of experience from the four major MOH hospitals in Jeddah with operational adult ICUs. A self-administered online questionnaire was utilized for data collection. Descriptive statistics, t-tests, ANOVA, and Pearson correlation were employed for data analysis.  Results: A total of 203 nurses completed the questionnaire (response rate: 91.5%). The overall knowledge score was 71%. Only 20% of nurses answered over 90% of the knowledge questions correctly, and merely 8% answered all questions correctly. Higher knowledge levels were significantly associated with older age, longer ICU nursing experience, higher education, holding a head nurse position, and attending educational courses on CLABSI prevention. Regarding attitudes, 58% of respondents had a positive perception of guideline utility for CLABSI prevention. In terms of adherence, the overall score was 65%, with only 5% reporting complete adherence to evidence-based practices for preventing CLABSIs.  Conclusion: This study highlights knowledge gaps, suboptimal adherence, and the need for targeted interventions to enhance nurses' understanding of and adherence to evidence-based guidelines for preventing CLABSIs among adult ICU nurses in Jeddah's MOH hospitals. Enhancing knowledge, attitudes, and practice adherence is crucial for reducing CLABSI risks and improving patient outcomes. Further research investigating the factors influencing nurses' knowledge, acceptance, and application of evidence-based guidelines is warranted to inform the development of tailored interventions and educational strategies.

Antiseptic barrier caps in central line-associated bloodstream infections: A systematic review and meta-analysis

OBJECTIVES

To evaluate the evidence concerning the effectiveness of antiseptic barrier caps vs. manual disinfection in preventing central line-associated bloodstream infection (CLABSI).

METHODS

The protocol of this systematic review and meta-analysis was pre-registered in PROSPERO (CRD42021259582). PubMed, Cochrane Library and Web of Science databases were searched from 2011 to 2021. Randomized-controlled trials (RCT) and observational studies on hospitalized patients of any age were included.

RESULTS

Fourteen studies were included. Compared with manual disinfection, antiseptic barrier caps significantly reduced CLABSI rate per 1000 line-days (Standardized Mean Difference [SMD]: -0.02; 95%CI: -0.03 to -0.01) and number of CLABSI per patient (RR: 0.60; 95%CI: 0.41-0.89). Subgroup analysis showed that antiseptic barrier caps were more effective in reducing CLABSI rate per 1000 line-days in ICU (SMD: -0.02; 95%CI: -0.03 to -0.01) and non-ICU patients (SMD: -0.03; 95%CI: -0.05 to -0.01), adults (SMD: -0.02; 95%CI: -0.04 to -0.01), as in observational studies (SMD: -0.02; 95%CI: -0.02 to -0.01). Antiseptic barrier caps also significantly reduce CLABSI risk in ICU patients (RR: 0.65, 95%CI: 0.42-1.00), adults (RR: 0.50, 95%CI: 0.29-0.86), and observational studies (RR: 0.54; 95%CI: 0.32-0.91). No differences were found when only children or RCTs were taken into account. Median cost savings amongst studies were $21,890 [IQR 16,350-45,000] per CLABSI.

CONCLUSIONS

Antiseptic barrier caps appear to be effective in reducing CLABSI. The real-world impact needs to be confirmed by RCTs.

Adaptation and validation of pediatric peripheral intravenous catheter insertion and care practices audit tools

Objectives

This study aimed to describe the translation process and establish the validity of the three instruments in Indonesian to assess pediatric peripheral intravenous catheter (PIVC) insertion and care practices.

Methods

The six-step forward and backward translation method was used to translate the adapted questionnaires. The English version questionnaires included the point prevalence audit checklist, the nurse survey consisting of the nurse PIVC knowledge questionnaire and the nurse PIVC confidence questionnaire, plus a Patient/parent Experience Survey. Data collection was conducted in Indonesia between October 2019 and February 2020. In total, there were six translators (two for each instrument), nine-panel vascular access experts (three for each instrument), and 30 participants (ten for each instrument) of the target population involved in the translation and validation of the three instruments. Three-panel experts rated the content relevance of each instrument using a four-point rating scale. Item level and scale level content validity index and kappa index were calculated. Ten-panel members of the target population evaluated each questionnaire regarding feasibility, clarity, logical sequence, and formatting. Qualitative comments from the panel were also reviewed.

Results

The translation process indicated relatively low discrepancies between translators except for semantic equivalence. There were nine, eight, and one semantic discrepancies found in the forward translation of the point prevalence audit checklist, nurse survey, and patient/parent experience survey. The semantic discrepancies were less prevalent in the backward translation, with only one, three, and two items reported during the process. The item validity index for all of the three instruments showed relatively high agreement between experts (I-CVI > 0.78, S-CVI/Ave >0.90, S-CVI/UA > 0.70, and kappa index >0.74). The face validity was established with the panel reporting that the three instruments were easy to understand and presented logically. However, some re-formatting of the nurse survey and patient/parent experience survey were needed to avoid ambiguity and confusion for the participants.

Conclusions

The results indicate that the translated three survey instruments that had been widely used in other developed countries show good content validity in the Indonesian context. They can be used as a reference for further testing in different countries and contribute to understanding the pediatric PIVC audit tools used in future clinical research.

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

BACKGROUND

Central line-associated bloodstream infections (CLABSI) have been a significant challenge in care, increasing healthcare costs and leading to adverse outcomes, including mortality.

AIMS AND OBJECTIVES

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.

DESIGN

A cross-sectional study.

METHODS

Data were collected from adult, paediatric, and neonatal ICU nurses working in seven hospitals in Iran, using census sampling from April to July 2020.

RESULTS

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.

CONCLUSIONS

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.

RELEVANCE TO CLINICAL PRACTICE

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.

Factors influencing knowledge, awareness, and compliance with standard precautions among psychiatric nurses

This study aimed to assess the level of knowledge, awareness, and compliance with standard precautions and to examine individual factors related to compliance with standard precautions among psychiatric nurses. Data were collected from September 2020 to March 2021. A total of 160 questionnaires were distributed, and a total sample of 134 valid questionnaires was analyzed. Compliance with standard precautions was significantly correlated with knowledge and awareness. Awareness (β = 0.547, p < .001) was a significant factor of compliance with a total explanatory power of 35.0% (F = 7.27, p < .001). Thus, the current coronavirus disease pandemic has significantly influenced the mental health infection system. These findings highlighted that psychiatric nurse must continue their efforts to improve compliance with infection prevention to prepare for an uncertain future with potential pandemics.

Knowledge of infection prevention and control among healthcare workers and factors influencing compliance: a systematic review

BACKGROUND

Knowledge of infection prevention and control (IPC) procedures among healthcare workers (HCWs) is crucial for effective IPC. Compliance with IPC measures has critical implications for HCWs safety, patient protection and the care environment.

AIMS

To discuss the body of available literature regarding HCWs' knowledge of IPC and highlight potential factors that may influence compliance to IPC precautions.

DESIGN

A systematic review. A protocol was developed based on the Preferred Reporting Items for Systematic reviews and Meta-Analysis [PRISMA] statement.

DATA SOURCES

Electronic databases (PubMed, CINAHL, Embase, Proquest, Wiley online library, Medline, and Nature) were searched from 1 January 2006 to 31 January 2021 in the English language using the following keywords alone or in combination: knowledge, awareness, healthcare workers, infection, compliance, comply, control, prevention, factors. 3417 papers were identified and 30 papers were included in the review.

RESULTS

Overall, the level of HCW knowledge of IPC appears to be adequate, good, and/or high concerning standard precautions, hand hygiene, and care pertaining to urinary catheters. Acceptable levels of knowledge were also detected in regards to IPC measures for specific diseases including TB, MRSA, MERS-CoV, COVID-19 and Ebola. However, gaps were identified in several HCWs' knowledge concerning occupational vaccinations, the modes of transmission of infectious diseases, and the risk of infection from needle stick and sharps injuries. Several factors for noncompliance surrounding IPC guidelines are discussed, as are recommendations for improving adherence to those guidelines.

CONCLUSION

Embracing a multifaceted approach towards improving IPC-intervention strategies is highly suggested. The goal being to improve compliance among HCWs with IPC measures is necessary.

Nurses and physicians knowledge of guidelines for preventing catheter-related blood stream infections

BACKGROUND

Catheter-related blood stream infection (CRBSI) is considered a major challenge for health care providers working in intensive care units.

AIM

This study aimed to evaluate and compare the knowledge of evidence-based guidelines for preventing catheter-related blood Stream infections among physicians and nurses working in critical care units in Jordan.

DESIGN

A cross-sectional survey design was utilized.

METHODS

The study was conducted in five intensive care units; 181 nurses and 68 physicians were recruited from four governmental hospitals and one university-affiliated hospital.

RESULTS

The mean total knowledge score for physicians' knowledge was low at 2.6, SD 1.5 (out of 10). While the mean total score for nurses' knowledge was low at 3.3, SD 1.8 (out of 10). The independent t test shows that nurses had a significantly higher mean total knowledge score than physicians (P < .05).

CONCLUSIONS

The current study demonstrates that Jordanian nurses and physicians working in intensive care units have a low level of knowledge of the guidelines for preventing CRBSI. This problem should be addressed through routine assessment and evaluation and adoption and policies that make nurses and physicians comply with the evidence-based guidelines. Finally, conducting regular educational programmes on CRBSI prevention, and evaluation of compliance with the guidelines in daily clinical practice, are strongly recommended.

RELEVANCE TO CLINICAL PRACTICE

The results of the current study suggest the need for regular assessment of physicians' and nurses' knowledge and skills with regard to central venous catheter insertion and maintenance care. Based on this assessment and using the best available evidence, training programmes on the prevention of CRBSI should be developed. Courses might be online, face to face, or using high fidelity simulation. Finally, regular observation and evaluation of compliance with the CRBSI guidelines in daily clinical practice is needed.

Knowledge, perceptions and experiences of nurses in antimicrobial optimization or stewardship in the intensive care unit

There is an urgent and recognized need for an interprofessional collaborative approach to support global action in addressing antimicrobial resistance (AMR). Antimicrobial stewardship (AMS) refers to systematic approaches for antimicrobial optimization within healthcare organizations. In areas with high antimicrobial utilization such as intensive care units (ICUs), specific roles for nurses in AMS are not clearly defined. This review aimed to identify and to critically evaluate primary studies that examined knowledge, perspectives and experiences of nurses associated with antimicrobial use and optimization in ICUs. A systematic search of Medline, CINAHL, PsychINFO, EMBASE, PubMed, SCOPUS, Cochrane Library and Web of Science databases for primary studies published from 1^st January 2000 to 20^th March 2020 was performed. A convergent synthesis design was used to synthesize quantitative and qualitative data. Of the 898 studies initially screened, 26 were included. Most (18/26) studies were quantitative. All qualitative studies (6/26) were of high methodological quality. Studies where interventions were used (10/26) identified significant potential for ICU nurses to reduce antimicrobial use, time-to-antibiotic administration, and error rates. Barriers to nursing engagement included knowledge deficits in antimicrobial use, interprofessional dissonance and the culture of deference to physicians. Enhancing education, technology utilization, strong nursing leadership and robust organizational structures that support nurses were perceived as enablers to strengthen their roles in optimizing antimicrobial use. This review showed that nursing initiatives have significant potential to strengthen antimicrobial optimization in ICUs. Barriers and enablers to active engagement were identified.

Prevention of central line-associated bloodstream infections: a survey of ICU nurses' knowledge and practice in China

Background

Central line-associated bloodstream infections (CLABSI) are largely preventable when evidence-based guidelines are followed. However, it is not clear how well these guidelines are followed in intensive care units (ICUs) in China. This study aimed to evaluate Chinese ICU nurses’ knowledge and practice of evidence-based guidelines for prevention of CLABSIs issued by the Centers for Disease Control and Prevention, US and the Department of Health UK.

Method

Nurses completed online questionnaires regarding their knowledge and practice of evidence-based guidelines for the prevention of CLABSIs from June to July 2019. The questionnaire consisted of 11 questions, and a score of 1 was given for a correct answer (total score = 0–11).

Results

A total of 835 ICU nurses from at least 104 hospitals completed the questionnaires, and 777 were from hospitals in Guangdong Province. The mean score of 11 questions related to evidence-based guidelines for preventing CLABSIs was 4.02. Individual total scores were significantly associated with sex, length of time as an ICU nurse, educational level, professional title, establishment, hospital grade, and incidence of CLABSIs at the participant’s ICU. Importantly, only 43% of nurses reported always using maximum barrier precautions, 14% of nurses reported never using 2% chlorhexidine gluconate for antisepsis at the insertion site, only 40% reported prompt removal of the catheter when it was no longer necessary, and 33% reported frequently and routinely changing catheters even if there was no suspicion of a CLABSI.

Conclusion

Chinese ICU nurses in Guangdong Province lack of knowledge and practice of evidence-based guidelines for the prevention of CLABSIs. National health administrations should adopt policies to train ICU nurses to prevent CLABSIs.

Assessing nursing students' knowledge of evidence-based guidelines on the management of peripheral venous catheters: A multicentre cross-sectional study

BACKGROUND

Inserting Peripheral Venous Catheters (PVCs) is one of the most routinely performed invasive procedures in nursing care and, if not well managed, it could expose patients to bloodstream-related infections. Knowledge of guidelines for the management of PVCs is fundamental to arise nurses and nursing students (NSs)' awareness on the importance of recommendations' adherence for clinical practice improvement.

OBJECTIVE

To determine NSs' theoretical knowledge of evidence-based guidelines for management of PVCs and investigate potential predictive factors associated to recommendations' adherence.

DESIGN

Cross-sectional.

SETTINGS

The study was carried out (March-September 2015) in seven Universities of three Regions of Italy (Marche, Abruzzo, Emilia Romagna).

PARTICIPANTS

A convenience sample of NSs (n = 1056) was involved.

METHODS

We collected data using a 10-items validated questionnaire assessing: knowledge of NSs' PVC guidelines and socio-demographic characteristics of the sample.

RESULTS

Most participants were female (74.8%), mean age: 22.4 years (DS = 3.9); attending the first, second and third year of Bachelor in Nursing (34.8%; 32.9%; 32.3%, respectively); with at least one year of training experience (32.1%). Most of incorrect answers given by NSs concerned the right way to wash hands before CVPs insertion (33.5%); the replacement of administration set <24 h when neither lipid emulsions nor blood products have been infused (79.7%); the choice of dressing to cover insertion site (59.3%); the use of steel needles to administer drugs (60.9%); the use of antibiotic ointment (68.7%); the correct concentration of chlorhexidine before PVCs' insertion (70.7%). In multivariate analysis, a higher level of education and an increased number of years of training experience and wards attended, were associated with better test scores. "Infusionset removal after 24 h when lipids or blood products are administered" (75.4%).

CONCLUSIONS

NSs' overall level of knowledge to some recommendations is inadequate. Nurse educators should emphasize on the importance of Evidence-based guidelines' knowledge in order to promote the translation of theory into practice of NSs.

The adherence to guidelines for preventing CVC-related infections: a survey among Italian health-care workers

Background

Since correct maintenance of intravascular catheters is an effective strategy for preventing central-line infections, the aim of this study was to assess the level of adherence to guidelines for CVC maintenance amongst Italian HCWs.

Methods

From July 2016 thru January 2017, a cross sectional survey was carried out in a random sample of 549 HCWs working in different hospitals of Campania region (Italy).

Results

The 68.9% of interviewees returned the questionnaire. Overall, respondents’ level of knowledge about CDC guidelines was low, with only the 20.7% of HCWs acknowledging guidelines main recommendations: the nurse stuff, the availability of hospital internal protocols, the use of guidelines themselves as source of information, and higher number of years of practice were significantly associated with a higher level of knowledge. An extremely positive attitude towards the utility of guidelines for preventing CVC-related infections was shown, with a linear regression model indicating a stronger attitude in physicians, in who knew the CDC main recommendations and correct use of antibiotic ointments, as well as in HCWs needing additional information on the prevention of CVC-related infections. Regarding the behaviors, physicians were more likely to be adherent about recommended evidence-based practices. Two more multivariate logistic and ordinal logistic regression models were built to investigate characteristics associated with correct behavior regarding the removal of catheter dressing if patients have tenderness at insertion site or fever without an obvious source, respectively.

Conclusions

This study reflected an important lack of evidence-based knowledge and practices regarding the CVC management, highlighting the baseline role of education and training programs, as well as pointing out the role of organizational interventions to address the adherence to best practices for the reduction of CLABSIs.

Gastric residual volume measurement in the intensive care unit: an international survey reporting nursing practice

BACKGROUND

Gastric residual volume measurement is routinely used to evaluate the feeding tolerance and gastro-oesophageal reflux in patients receiving enteral feeding therapy in the intensive care unit. However, little supportive evidence for this intervention is available as the usefulness of gastric residual volume measurements in patients receiving enteral feeding therapy in the intensive care is controversial.

AIM

The aim of this study was to assess the practice of intensive care unit nurses related to gastric residual volume measurement in patients receiving enteral nutrition.

METHODS

A survey was conducted among a sample of intensive care unit nurses (n = 832) from four hospitals in Turkey (n = 182) and attendees of the Annual Congress of the Flemish Society for Critical Care Nurses in Flanders, Belgium (n = 650). The survey instrument was developed by the researchers based on the related literature.

RESULTS

A total of 480 nurses completed the questionnaire (response rate = 73%). Gastric residual volume is measured by 98·0% of respondents, with wide variations in the frequency of measuring. A 50-200 mL gastric residual volume is considered problematic by 45·5% (n = 183) of the participants, and only 18·4% (n = 81) reported their practice to be based on a current guideline. Strikingly, more experienced intensive care unit nurses appear to perform gastric residual volume measurements more commonly than their less experienced colleagues (p = 0·004), while the practice is more often reported to be performed in Belgium than in Turkey (p < 0·001).

CONCLUSION

Gastric residual volume management could be improved by applying current evidence to daily nursing practice.

RELEVANCE TO CLINICAL PRACTICE

Our results show that increased awareness of these guidelines by nurses is needed to reduce inefficient use of working time and resources, streamline clinical practices and improve patient outcomes. Current gastric residual volume measurement guidelines and up-to-date, relevant training should be provided to nurses.

Educating intensive care unit nurses to use central venous catheter infection prevention guidelines: effectiveness of an educational course

Background

Nurses' knowledge of central venous catheter-related infection (CVC-RI) prevention guidelines is poor, indicating that nurses do not receive proper education about these guidelines.

Aim

The aim of this study was to evaluate the effectiveness of an educational course that aimed to improve nurses' knowledge about CVC-RI prevention guidelines.

Method

A sample of 131 nurses were randomly assigned to the experimental group (received an educational course) or control group (received no education). Pre-Post data were collected using a structured questionnaire that included a 23-item knowledge assessment.

Results

In the pre-test, all participants demonstrated poor knowledge, with mean scores of 8.2 (standard deviation = 3.6). After completion of the course, knowledge was significantly improved in the experimental group, whereas the control group showed no change (t(106,3) = 25.1, p = 0.00).

Conclusions

An educational course on CVC-RI prevention guidelines had an encouraging effect. Decision makers are recommended to implement such courses in their settings to improve nurses' competency.

Effect of an acrylic terpolymer barrier film beneath transparent catheter dressings on skin integrity, risk of dressing disruption, catheter colonisation and infection

OBJECTIVES

We assessed the effect of a skin-protective terpolymer barrier film around the catheter insertion site on frequency of dressing disruptions and skin integrity issues (hyperaemia, skin irritation, residues of adhesives and moisture under the dressing). Secondary outcomes included colonisation of the central venous catheter (CVC) and rates of central line-associated bloodstream infection.

RESEARCH METHODOLOGY

A monocentric, open-label, randomised controlled trial was performed comparing a control group receiving standard transparent catheter dressings without the skin-protecting barrier film and an intervention group receiving a transparent chlorhexidine-impregnated dressing with use of the skin-protective acrylic terpolymer barrier film (3M™ Cavilon™ No - Sting Barrier Film, 3 M Health Care, St. Paul, MN, USA).

RESULTS

Sixty patients were enrolled and randomised in the study accounting for 60 central venous catheters and a total of 533 catheter days. Dressing disruptions occurred more frequently and at sooner time point in the control group. Skin integrity issues were significantly less observed in the intervention group. No differences in CVC colonisation or central line-associated bloodstream infection were observed.

CONCLUSIONS

The application of a barrier film creating a skin-protective polymer layer beneath transparent catheter dressings is associated with less dressing disruptions and skin integrity issues without altering the risk of infectious complications if used in combination with a chlorhexidine-impregnated catheter dressing.

Impact of a training program on adherence to recommendations for care of venous lines in internal medicine departments in Spain

A high percentage of venous lines (VLs) are placed in non-ICU patients, particularly those treated in the internal medicine department (IMD). We assessed adherence to VL care after a training program aimed at nurses and clinicians attending patients admitted to Spanish IMDs. We performed a multicenter prospective observational point prevalence study in 14 Spanish IMDs in 2013 and 2016. We included all adult patients (> 18 years) admitted to IMDs on the study day and reviewed nursing records for patients with VL in place before and after a 1-year training program during 2015. Answers from an interview with head nurses of the IMDs regarding commonly used practices in the daily management of VLs were also compared. A total of 638 and 693 patients were seen during each period, respectively, and 530 and 598 patients had ≥ 1 VL implanted (83.1 vs. 86.3%). Catheters were considered unnecessary in 12.8 and 15.0% of cases (p = 0.28). Daily recording of the need for catheter use increased from 43.8 to 71.8% (p < 0.001). Furthermore, daily monitoring of the insertion site remained very frequent (94.4 vs. 92.2%; p = 0.16). The date of insertion was recorded in 86.3 and 85.5% of cases (p = 0.73), and no combination of closed connectors with open caps increased from 74.8 to 90.3% (p < 0.001). Overall, head nurses' knowledge improved in 4 out of 14 recommendations assessed (28.6%). A simple and easy program for training on management of VLs in Spanish IMDs was associated with improved quality of care.

IMPACTO DA IMPLEMENTAÇÃO DOS BUNDLES NA REDUÇÃO DAS INFECÇÕES DA CORRENTE SANGUÍNEA: UMA REVISÃO INTEGRATIVA

RESUMO Objetivo: analisar as produções científicas nacionais e internacionais sobre o impacto dos bundles na prevenção de infecção da corrente sanguínea relacionada ao cateter venoso central em unidade de terapia intensiva adulta. Método: revisão integrativa de artigos publicados no Portal Capes, Biblioteca Virtual em Saúde, PubMed, Science Direct, Cochrane, CINAHL e SCOPUS, entre 2011 e 2016. Resultados: encontraram-se 16 artigos, 100% relacionados à implementação dos bundles para a inserção do cateter venoso central e 50% à manutenção deste dispositivo. O tempo de intervenção foi variado, bem como o número de medidas e o período analisado (inserção/manutenção do cateter). No entanto, a redução da infecção da corrente sanguínea relacionada ao dispositivo foi apontada em todos os estudos entre 26% e 100%. Conclusão: a adoção de bundle evidenciou um impacto positivo na redução da infecção. Todavia, não se observou uma relação direta entre o número de medidas descritas nos estudos ou o maior tempo de implementação e taxas mais altas de redução da infecção.

A New Central venous Catheter Cap: Decreased Microbial Growth and Risk for Catheter-Related Bloodstream Infection

Objective

Catheter-related blood stream infection (CRBI) is a major cause of morbidity and mortality, and is a source of significant healthcare expenditures in patients that require central venous catheters for intravenous nutrition, chemotherapy, and other products. The source of many catheter-related infections is contamination of the catheter hub. Herein an antimicrobial catheter cap, the AB Cap is described.

Methods

The AB Cap device is a catheter cleaning device designed to keep needleless luer valves clean by encapsulating them in a cleaning solution. This device was evaluated using an in vitro model of hub contamination with Staphylococcus aureus, Staphylococcus epidermidis (S. epidermidis), Klebsiella pneumonia (K. pneumonia), Pseudomonas aeruginosa, Escherichia coli and Candida albicans (C. albicans). Following hub contamination on days 1, 3, 5 and 7, saline was infused through the AB Cap and effluent collected from the efferent end. The effluent fluid was cultured for the index organisms, and allowed to incubate in culture for up to 7 days. Negative control caps were not contaminated and positive controls lacked cleaning solution and were contaminated.

Results

Microbial growth developed for all index organisms, and generally within 1 day of culture growth following the first day of contamination (day 1) in effluent from all positive controls, while no growth occurred in effluent from negative controls. No growth of any organism occurred in any of the test items after the first day of contamination. Growth of three organisms was detected in two of the three test AB Caps following contamination day 3, after 1–4 days of incubation. All organisms could be cultured in the effluent from two of the three test items at contamination day 5, generally by the second day of incubation. One test item remained free of growth for the entire test period except for one organism. By day 7, this particular test item grew an additional organism and the testing was concluded. All positive growth test items remained positive on subsequent inoculations during culture of newly obtained effluent with the exception of test item A, from which effluent following inoculation on day 3 showed growth of S. epidermidis and K. pneumonia, but no growth for these organisms from effluent obtained on inoculation day 5. In addition, effluent from test item C showed growth of C. albicans from inoculation day 5, but no growth from effluent obtained on inoculation day 7. The growth of S. epidermidis from effluent of test item A from the day 3 inoculation, and C. albicans from effluent of test items B and C did not occur until day 4 of incubation, suggesting a very small amount of contamination.

Conclusion

An antimicrobial catheter cap is not a complete substitute for a proper catheter cleaning technique and other anti-infection precautions. However, we describe a unique catheter cap that significantly decreased the likelihood of a catheter-related infection from a non-cleaned cap in an in vitro model.

Knowledge, attitudes, and practice on the prevention of central line-associated bloodstream infections among nurses in oncological care: A cross-sectional study in an area of southern Italy

The objectives of the cross-sectional study were to delineate the knowledge, attitudes, and behavior among nurses regarding the prevention of central line-associated bloodstream infections (CLABSIs) and to identify their predisposing factors. A questionnaire was self-administered from September to November 2011 to nurses in oncology and outpatient chemotherapy units in 16 teaching and non-teaching public and private hospitals in the Campania region (Italy). The questionnaire gathered information on demographic and occupational characteristics; knowledge about evidence-based practices for the prevention of CLABSIs; attitudes towards guidelines, the risk of transmitting infections, and hand-washing when using central venous catheter (CVC); practices about catheter site care; and sources of information. The vast majority of the 335 nurses answered questions correctly about the main recommendations to prevent CLABSIs (use sterile gauze or sterile transparent semipermeable dressing to cover the catheter site, disinfect the needleless connectors before administer medication or fluid, disinfect with hydrogen peroxide the catheter insertion site, and use routinely anticoagulants solutions). Nurses aged 36 to 50 years were less likely to know these main recommendations to prevent CLABSIs, whereas this knowledge was higher in those who have received information about the prevention of these infections from courses. Nurses with lower education and those who do not know two of the main recommendations on the site’s care to prevent the CLABSIs, were more likely to perceive the risk of transmitting an infection. Higher education, attitude toward the utility allow to dry antiseptic, and the need of washing hands before wearing gloves for access to port infusion were predictors of performing skin antiseptic and aseptic technique for dressing the catheter insertion site. Educational interventions should be implemented to address the gaps regarding knowledge and practice regarding the prevention of CLABSIs and to ensure that nurses use evidence-based prevention interventions.

The Value of E-Learning for the Prevention of Healthcare-Associated Infections

BACKGROUND Healthcare workers (HCWs) lack familiarity with evidence-based guidelines for the prevention of healthcare-associated infections (HAIs). There is good evidence that effective educational interventions help to facilitate guideline implementation, so we investigated whether e-learning could enhance HCW knowledge of HAI prevention guidelines. METHODS We developed an electronic course (e-course) and tested its usability and content validity. An international sample of voluntary learners submitted to a pretest (T0) that determined their baseline knowledge of guidelines, and they subsequently studied the e-course. Immediately after studying the course, posttest 1 (T1) assessed the immediate learning effect. After 3 months, during which participants had no access to the course, a second posttest (T2) evaluated the residual learning effect. RESULTS A total of 3,587 HCWs representing 79 nationalities enrolled: 2,590 HCWs (72%) completed T0; 1,410 HCWs (39%) completed T1; and 1,011 HCWs (28%) completed T2. The median study time was 193 minutes (interquartile range [IQR], 96-306 minutes) The median scores were 52% (IQR, 44%-62%) for T0, 80% (IQR, 68%-88%) for T1, and 74% (IQR, 64%-84%) for T2. The immediate learning effect (T0 vs T1) was +24% (IQR, 12%-34%; P300 minutes yielded the greatest residual effect (24%). CONCLUSIONS Moderate time invested in e-learning yielded significant immediate and residual learning effects. Decision makers could consider promoting e-learning as a supporting tool in HAI prevention. Infect Control Hosp Epidemiol 2016;37:1052-1059.

Prevention of central venous catheter-associated bloodstream infections: A questionnaire evaluating the knowledge of the selected 11 evidence-based guidelines by Polish nurses

This study evaluated the questionnaire testing nurses' knowledge about the maintenance of a central venous catheter (CVC) and assessed it with regard to age, work experience, type of ward, frequency of trainings, and postgraduate education. There were 1,180 questionnaires (N = 784; 66.4% of the total sample) distributed in several regions of Poland for a period of 7 months. The difficulty level for each question ranged from 0.22-0.88.

Improving Registered Nurses' Knowledge of Evidence-Based Practice Guidelines to Decrease the Incidence of Central Line-Associated Bloodstream Infections: An Educational Intervention

Background: The 2011 Centers for Disease Control and Prevention guidelines provide evidence-based recommendations for preventing central line-associated bloodstream infection (CLABSI). Educating and training health care personnel—incorporating bundled strategies for maximizing patient safety throughout the course of intravenous therapy—is the major area of interest. Despite a low number of reported CLABSIs—below national benchmarks—our large regional medical center has the goal of 0 CLABSI.

Purpose: The purpose of our project was to develop an educational intervention guided by the Healthcare and Technology Synergy Framework to improve registered nurses' (RNs) knowledge of evidence-based practice guidelines to decrease the incidence of CLABSI.

Methodology: A pretest/posttest format was used to evaluate an educational session on the nursing management of central lines (CLs). Participants in the study were RNs employed at a large regional medical center who worked 50% or more per week providing direct patient care in the hospital's intensive care units. An educational session on nursing management of CLs was presented. A 16-question survey (7 demographic and 9 knowledge questions) to assess RNs' knowledge of care and maintenance of CLs was used as the pretest and posttest.

Conclusions: RNs' knowledge of care and maintenance of CLs improved significantly after the intervention (pretest mean score = 4.6 and posttest mean score = 8.4; P = .0001).

Implications for Practice: An educational intervention can increase RNs' knowledge of care of CLs. As a result of this project, an annual evidence-based practice educational intervention was adopted for RNs at our large regional medical center.

An Ounce of Prevention Saves Tons of Lives: Infection in Burns

BACKGROUND

Modern day burn care continues to wage an uphill battle against an enemy that evolves faster than we can develop weapons. Bacteria (bioburden) are everywhere and can infiltrate anywhere within our susceptible population of burn patients. This is why prevention of infection is key to improving their survival and outcome.

PURPOSE

To reduce the incidence of infection in the burn patient population.

MATERIALS

Review of pertinent recent literature regarding infection prevention and control in the intensive care unit setting.

RESULTS

We propose that bioburden is one of the central elements in the infectious cycle that is ever-present in burn units. The mechanism of bacterial entry into the unit and subsequent transmission and infection are delineated. Recommendations for mitigating this risk are provided to guide future clinicians in their care of burn patients.

CONCLUSIONS

The treatment of infection and sepsis against highly adaptable bacteria is often insurmountable by ill patients. In this process, bioburden needs to be corralled to have any success. Thus, preventing organisms from entering the unit and transferring onto other patients, and eliminating the bacteria dwelling in the unit are all necessary actions in this battle. Ultimately, maintaining a culture that is constantly wary of this risk only can achieve this goal.

Examining the Role of Securement and Dressing Products to Prevent Central Venous Access Device Failure: A Narrative Review

Objective: To describe the underpinning principles involved in central venous access device (CVAD) securement and dressing products to prevent CVAD failure and complications through a synthesis of research studies.

Background: Functional, dependable CVADs are a necessary part of patient care. Dressing and securement products are used to prevent CVAD failure and complications, but there is a large variety of products available for clinicians to access, with variable effectiveness.

Methods: A narrative review of studies describing the mechanisms for CVAD securement and dressing products to prevent failure and complication was undertaken. After a systematic search, 20 clinical and laboratory studies were included in the review.

Discussion: The major mechanisms by which CVAD dressing and securement products prevent failure are providing a barrier to microbial contamination and motion reduction. CVAD securement and dressing products provide these functions using coating, adhesion, antimicrobial properties, absorbency, and moisture vapor transmission without causing irritation to skin and maintaining visibility of the insertion site. The complexity of patients requiring CVAD securement and dressing means that universal recommendations across CVAD populations and broad generalization of studies from single populations (eg, intensive care) or devices (eg, peripherally inserted central catheters) are ill advised.

Conclusions: CVAD securement and dressing products provide important, multifaceted functions to prevent CVAD failure and complication.

Nationwide study on the use of intravascular catheters in internal medicine departments

BACKGROUND

The use of intravascular catheters (IVCs) in intensive care units (ICUs) has been well assessed in recent years. However, a high proportion of these devices are placed in patients outside the ICU, particularly in internal medicine departments (IMDs), where data on the quality of care are scarce.

AIM

To assess the use and management of IVCs in IMDs in Spain.

METHODS

We performed a point prevalence study of all adult inpatients on 47 IMDs from hospitals of different sizes on one day in June 2013. A local co-ordinator was appointed to assess patients and collect data from each site.

FINDINGS

Out of the 2080 adult patients hospitalized on the study day, 1703 (81.9%) had one or more IVCs (95.4% of which were peripheral devices). Infection was detected at the insertion site in 92 catheters (5.0%); 87 patients (5.2%) had signs of sepsis, but only one case was considered to be catheter-related. The local co-ordinators estimated that 19% of the catheters in place were no longer necessary. A daily record of the need for a catheter was available in only 40.6% of cases.

CONCLUSION

Our study shows clear opportunities for improvement regarding catheter use and care in Spanish IMDs. Strategies similar to those applied in ICUs should be implemented in IMDs.

A Simple Educational Intervention to Decrease Incidence of Central Line–Associated Bloodstream Infection (CLABSI) in Intensive Care Units with Low Baseline Incidence of CLABSI

After an educational intervention in 3 intensive care units, 34 central line-associated bloodstream infections occurred in 11,582 central venous catheter [CVC]-days, compared with 45 episodes in 10,661 CVC-days before intervention (4.22 vs 2.94 episodes per 1,000 CVC-days [30.9% reduction]; P = .03, Wilcoxon rank sum test; P = .11, Poisson regression analysis).

Health care workers' knowledge and practices regarding the prevention of central venous catheter-related infection

BACKGROUND

Central venous catheter-related infection (CVC-RI) is considered a common cause of increased morbidity, mortality, and medical care costs in intensive care units (ICUs). The objective in this descriptive study was to assess the knowledge of health care workers in ICUs about guidelines for the prevention of CVC-RI and their adherence to these guidelines in practices.

METHODS

Health care workers were assessed for their actual practices during central venous catheter (CVC) insertion and care. Then a questionnaire was distributed to the health care workers to assess their knowledge regarding the prevention of CVC-RI.

RESULTS

All the health care workers (N = 100; 40 physicians, 60 nurses) in the ICUs (levels I and III and triage) of Alexandria Main University Hospital participated in the present study. The response rate was 100%. The total percentage of correct answers of the health care workers about the guidelines for the prevention of CVC-RI was low. There was no significant difference between physicians' and nurses' knowledge regarding the total score on the questionnaire (P = .134). However, physicians had a significantly higher knowledge about the pathophysiology of CVC-RI and skin antisepsis items than nurses. There were no significant differences between the knowledge of physicians and nurses in other items except for CVC care, where nurses showed significantly higher knowledge than physicians (P = .001).

CONCLUSION

The results of the present study revealed health care worker's low knowledge regarding the prevention of CVC-RI and low compliance with the standard guidelines of CVC care. Therefore, health care workers should be periodically evaluated for their knowledge and practices regarding guidelines for the prevention of CVC-RI.

Prevention of central line-associated bloodstream infections through quality improvement interventions: a systematic review and meta-analysis

This systematic review and meta-analysis examines the impact of quality improvement interventions on central line-associated bloodstream infections in adult intensive care units. Studies were identified through Medline and manual searches (1995-June 2012). Random-effects meta-analysis obtained pooled odds ratios (ORs) and 95% confidence intervals (CIs). Meta-regression assessed the impact of bundle/checklist interventions and high baseline rates on intervention effect. Forty-one before-after studies identified an infection rate decrease (OR, 0.39 [95% CI, .33-.46]; P < .001). This effect was more pronounced for trials implementing a bundle or checklist approach (P = .03). Furthermore, meta-analysis of 6 interrupted time series studies revealed an infection rate reduction 3 months postintervention (OR, 0.30 [95% CI, .10-.88]; P = .03). There was no difference in infection rates between studies with low or high baseline rates (P = .18). These results suggest that quality improvement interventions contribute to the prevention of central line-associated bloodstream infections. Implementation of care bundles and checklists appears to yield stronger risk reductions.

Prevention of central venous catheter infections: a survey of paediatric ICU nurses' knowledge and practice

BACKGROUND

Central venous catheters are important in the management of paediatric intensive care unit patients, but can have serious complications which worsen the patients' health, prolong hospital stays and increase the cost of care. Evidence-based recommendations for preventing catheter-related bloodstream infections are available, but it is unknown how widely these are known or practiced in the paediatric intensive care environment.

OBJECTIVES

To assess nursing knowledge of evidence based guidelines to prevent catheter-related bloodstream infections; the extent to which Australia and New Zealand paediatric intensive cares have adopted prevention practices; and to identify the factors that encouraged their adoption and improve nursing knowledge.

DESIGN

Cross-sectional surveys using convenience sampling.

SETTINGS

Tertiary level paediatric intensive care units in Australia and New Zealand.

PARTICIPANTS

Paediatric intensive care nursing staff and nurse managers.

METHODS

Between 2010 and 2011, the 'Paediatric Intensive Care Nurses' Knowledge of Evidence-Based Catheter-Related Bloodstream Infection Prevention Questionnaire' was distributed to paediatric intensive care nursing staff and the 'Catheter-Related Bloodstream Infection Prevention Practices Survey' was distributed to nurse managers to measure knowledge, practices and culture.

RESULTS

The questionnaires were completed by 253 paediatric intensive care nurses (response rate: 34%). The mean total knowledge score was 5.5 (SD=1.4) out of a possible ten, with significant variation of total scores between paediatric intensive care sites (p=0.01). Other demographic characteristics were not significantly associated with variation in total knowledge scores. All nursing managers from Australian and New Zealand paediatric intensive care units participated in the survey (n=8; response rate: 100%). Wide practice variation was reported, with inconsistent adherence to recommendations. Safety culture was not significantly associated with mean knowledge scores per site.

CONCLUSIONS

This study has identified that there is variation in the infection prevention approach and nurses' knowledge about catheter-related bloodstream infection prevention. The presence of an improved safety culture, years of paediatric intensive care experience and higher qualifications did not influence the nurses' uptake of recommendations, therefore further factors need to be explored in order to improve understanding and implementation of best practice.

Bloodstream infection in patients with end-stage renal disease in a teaching hospital in central-western Brazil

INTRODUCTION

Vascular access in patients undergoing hemodialysis is considered a critical determinant of bloodstream infection (BSI) and is associated with high morbidity and mortality. The purpose of this study was to investigate the occurrence of BSI in patients with end-stage renal disease using central venous catheters for hemodialysis.

METHODS

A cohort study was conducted in a public teaching hospital in central-western Brazil from April 2010 to December 2011. For every patient, we noted the presence of hyperemia/exudation upon catheter insertion, as well as fever, shivering, and chills during hemodialysis.

RESULTS

Fifty-nine patients were evaluated. Thirty-fi ve (59.3%) patients started dialysis due to urgency, 37 (62.7%) had BSI, and 12 (20%) died. Hyperemia at the catheter insertion site (64.9%) was a significant clinical manifestation in patients with BSI. Statistical analysis revealed 1.7 times more cases of BSI in patients with hypoalbuminemia compared with patients with normal albumin levels. The principal infective agents identified in blood cultures and catheter-tip cultures were Staphylococcus species (24 cases), non-fermentative Gram-negative bacilli (7 cases of Stenotrophomonas maltophilia and 5 cases of Chryseobacterium indologenes), and Candida species (6). Among the Staphylococci identified, 77.7% were methicillin-resistant, coagulase-negative Staphylococci. Of the bacteria isolated, the most resistant were Chryseobacterium indologenes and Acinetobacter baumannii.

CONCLUSIONS

Blood culture was demonstrated to be an important diagnostic test and identified over 50% of positive BSI cases. The high frequency of BSI and the isolation of multiresistant bacteria were disturbing findings. Staphylococcus aureus was the most frequently isolated microorganism, although Gram-negative bacteria predominated overall. These results highlight the importance of infection prevention and control measures in dialysis units.
