Implementing a better bundle to achieve and sustain a zero central line-associated bloodstream infection rate

Care bundles and peripheral arterial catheters

HIGHLIGHTS

What we know about the topic: Recommendations for the use of vascular access care bundles to reduce infection are followed for different devices. The risk of arterial catheter-related infection is comparable with short-term, non-cuffed central venous catheters. There are practice concerns for clinicians inserting and caring for peripheral arterial catheters. What this paper adds: The selected studies had a theme of decreased infection after using bundled strategies for all devices. Few studies addressed use of bundles for care of peripheral arterial catheters. High-quality research should be performed about using care bundles for insertion and care of arterial catheters.

INTRODUCTION

A scoping review of the literature was performed.

AIMS/OBJECTIVES

To find information on the use of care bundles for care of arterial, central, and peripherally inserted venous catheters.

METHODS

Data was extracted by 2 independent researchers using standardized methodology.

RESULTS

Results of 84 studies included 2 (2.4%) randomized controlled trials, 38 (45.2%) observational studies, 29 (34.5%) quality projects, and 15 (17.9%) reviews. Populations had more adults than pediatric patients. All studies had the most prominent theme of decreased infection in all devices after using bundle strategies.

DISCUSSION AND CONCLUSIONS

The mapping of available evidence strongly supports the use of care bundles to reduce infection in the care of all intravascular devices. However, deficiencies regarding practice concerns about insertion and care of arterial catheters highlight areas for future research with the aim to eliminate the gap in the evidence of studies of care bundles for peripheral arterial catheters.

SHEA Neonatal Intensive Care Unit (NICU) White Paper Series: Practical approaches for the prevention of central-line-associated bloodstream infections

This document is part of the "SHEA Neonatal Intensive Care Unit (NICU) White Paper Series." It is intended to provide practical, expert opinion, and/or evidence-based answers to frequently asked questions about CLABSI detection and prevention in the NICU. This document serves as a companion to the CDC Healthcare Infection Control Practices Advisory Committee (HICPAC) Guideline for Prevention of Infections in Neonatal Intensive Care Unit Patients. Central line-associated bloodstream infections (CLABSIs) are among the most frequent invasive infections among infants in the NICU and contribute to substantial morbidity and mortality. Infants who survive CLABSIs have prolonged hospitalization resulting in increased healthcare costs and suffer greater comorbidities including worse neurodevelopmental and growth outcomes. A bundled approach to central line care practices in the NICU has reduced CLABSI rates, but challenges remain. This document was authored by pediatric infectious diseases specialists, neonatologists, advanced practice nurse practitioners, infection preventionists, members of the HICPAC guideline-writing panel, and members of the SHEA Pediatric Leadership Council. For the selected topic areas, the authors provide practical approaches in question-and-answer format, with answers based on consensus expert opinion within the context of the literature search conducted for the companion HICPAC document and supplemented by other published information retrieved by the authors. Two documents in the series precede this one: "Practical approaches to Clostridioides difficile prevention" published in August 2018 and "Practical approaches to Staphylococcus aureus prevention," published in September 2020.

Qualitative interviews and supporting evidence to identify the positive impacts of multidisciplinary vascular access teams

BACKGROUND

Vascular access by means of intravenous catheters is essential for the safe, effective and cost-efficient delivery of intravenous fluids, antibiotics, nutrition and chemotherapy, but the use of these devices is not without complications.

PURPOSE

A faculty of multidisciplinary European vascular access team (VAT) Leads/Members and experts sought to reframe how the implementation of a VAT could have positive impacts on patients and hospitals.

METHODS

Interview data from a Faculty of nine VAT Leads/Members and experts from six European countries on the impact of multidisciplinary VATs in modern healthcare were assessed. A literature search was conducted that included Medline®-cited peer-reviewed articles published in the past 10 years in order to identify impact data and post-implementation of a multidisciplinary VAT that support the benefits to patient safety and satisfaction and to hospital efficiencies reported in the interview program.

RESULTS

While VATs vary in structure and function, clarity of purpose and supportive training and education are key. Barriers to the implementation of VATs show commonality across countries, such as lack of investment, insufficient training and lack of awareness. Proven markers of VAT success include rapid referrals, improved patient outcomes and improved organizational efficiency. Standardization of outcomes data capture, processing and reporting are key to monitoring performance against baseline. Awareness of the cost of complications arising from inappropriate choice and placement, and poor care and maintenance, of the vascular access device must be raised.

CONCLUSIONS

The implementation of VATs can positively impact patient safety and satisfaction, improve organizational efficiencies and cost-effectiveness, and could create new opportunities for in- and outpatient services, beneficial to both patients and institutions.

Impact of needle-free connectors compared with 3-way stopcocks on catheter-related bloodstream infection rates: A meta-analysis

BACKGROUND

Needle-free connectors (NFCs) were introduced to eliminate the use of needles in intravascular catheters, and their newest generations were designed to improve patient safety and reduce catheter-related bloodstream infection (CRBSI) risks. The aim of this meta-analysis was to compare NFCs with 3-way stopcocks (3WSCs) and their effects on CRBSI rates.

METHODS

A meta-analysis was conducted using a research protocol consistent with the PRISMA statement for reporting meta-analyses. The Cochrane Database of Systematic Reviews and MEDLINE were searched for relevant randomized studies published from January 2000 to September 2018.

RESULTS

We identified and selected for the meta-analysis 8 studies comparing CRBSI rates (according to the Centers for Disease Control and Prevention's National Healthcare Safety Network definition) associated with NFCs utilizing negative-displacement, neutral-displacement, or positive-displacement devices with rates for 3WSCs. Relative risk was 0.53 with a 95% CI of 0.28 to 1.00, and the relative difference was -0.018 with a 95% CI of -0.039 to 0.004.

CONCLUSIONS

CRBSI risk was statistically higher for 3WSCs compared to NFCs.

Clinical impact of needle-free connector design: A systematic review of literature

The objective of this systematic review is to analyze types of needle-free connectors and open systems and their effects on central line–associated bloodstream infection rates and other adverse outcomes through a research protocol consistent with the Preferred Reporting Items for Systematic Reviews’ recommendations. MEDLINE and Cochrane databases of systematic reviews were searched for relevant comparative studies published from January 2000 to September 2017. Eighteen studies compared central line–associated bloodstream infection (according to the Centers for Disease Control and Prevention/National Healthcare Safety Network definition), internal microbial contamination, occlusions, phlebitis, and other outcomes associated with needle-free connectors with a positive displacement device, negative displacement device, neutral displacement device, or three-way stopcock. Ten studies reported central line–associated bloodstream infection rates, which were lower with positive displacement devices versus negative displacement devices/neutral displacement devices (one study) and with negative displacement devices versus three-way stopcocks (three studies), but varied with different positive displacement device and negative displacement device/neutral displacement device designs (four studies). Seven studies reported internal microbial contamination rates, which were higher with three-way stopcocks versus negative displacement devices (two studies) and positive displacement devices (two studies), lower when positive displacement devices were used versus neutral displacement devices (one study), and varied with different types of negative displacement device (one study). Central line–associated bloodstream infection rates and most other outcomes analyzed were statistically significantly higher with three-way stopcocks (open devices) versus positive displacement device, negative displacement devices, and neutral displacement devices, but varied among closed device designs.

Achieving a Zero Central Line-Associated Bloodstream Infection Rate in 4 Critical Care Units in Lebanon

Every health care facility aims to achieve and maintain a zero central line-associated bloodstream infection (CLABSI) rate. Infections can be costly for institutions of any size and are often not covered by health insurance. The interventions put in place in this quality improvement project were implemented in 4 phases: (1) develop a new standard of care for central lines and give nurses full responsibility for the care and handling of these lines (including blood sampling); (2) revise policy and provide educational sessions to support nurses; (3) document compliance with the new policy; and (4) document CLABSI rates. The project took place during a 15-month period between January 1, 2016 and March 30, 2017, in 4 critical care units in a university medical center in Lebanon. The results revealed a reduction in CLABSI rates from a maximum rate of more than 17 per 1000 catheter days to zero per 1000 catheter days, which was sustained for 10 months. Nurse compliance with the new policy after 3 months ranged from 95% to 99%.

Best Practices in the Management of Central Vascular Access Devices: An Observational Study in Areas With a High Prevalence of Trained Nurses

Since 2009, the Department of Continuing Education at the Orthopedic and Trauma Center Hospital in Turin, Italy, has provided a training course for nurses in the management of central vascular access devices (CVADs). The course focuses on dressing and flushing procedures, as well as compliance with other CVAD guidelines. An observational study was conducted among nurses to determine the level of best practices in areas with a high prevalence of nurses trained in the management of CVADs. A correlation was observed between best practices and having attended the course, but other variables also influenced best practices.

Reduction of Central Line-Associated Bloodstream Infection Rates in Patients in the Adult Intensive Care Unit

Central line-associated bloodstream infections (CLABSIs) prolong hospital stays and increase cost, morbidity, and mortality. An intensive care unit (ICU) in a suburban Baltimore hospital reduced CLABSI rates to zero in 2012, by revising central venous access device policies and initiatives, which included a bloodstream infection alert system, bundle compliance monitoring and routine evaluation, and use of positive displacement needleless connectors. The hospital's ICU infection rate decreased from 2.9/1000 central-line days in 2010 to 0.8 by 2011, 0 by 2012, and 0.91 in 2013. The utilization ratio was 0.64 in 2011, 0.60 in 2012, and 0.58 in 2013. CLABSI prevention involves all disciplines and requires staff accountability for patient safety.

Needleless connectors: the vascular access catheter's microbial gatekeeper

Needleless connectors (NCs) are essential devices which connect to the end of vascular catheters and enable catheter access for infusion and aspiration. There are various different designs which make it difficult for purchasers to identify the features which present the least risk and greatest safety. The NC is the microbial gatekeeper for vascular catheters; how it is disinfected pre access determines if, and how many, organisms enter and how quickly biofilm will form. This paper will consider these design variations and how differences in antiseptic testing methods have made it difficult to determine the best antiseptic practice pre access. One specific design characteristic is considered: the fluid pathway. The NC's fluid pathway creates a flow which can be either direct to produce a laminar flow or indirect which creates a turbulent flow. At present, the evidence does not support there being an advantage for a specific fluid pathway design in reducing infection risks.

Use of a Central Catheter Maintenance Bundle in Long-Term Acute Care Hospitals

OBJECTIVE

Evidence-based guidelines have resulted in decreases in bloodstream infections associated with central catheters (CLABSIs) in hospital intensive care units. However, relatively little is known about CLABSI incidence and prevention in long-term acute care hospitals (LTACHs).

METHODS

A central catheter maintenance bundle was implemented in 30 LTACHs, and compliance with the bundle was tracked for 6 months. CLABSI rates were monitored for 14 months before and 14 months after the bundle was implemented.

RESULTS

The pooled mean CLABSI rate (No. of infections per 1000 days with a central catheter) was 1.28 before the bundle and 0.96 after the bundle (repeated measures general linear model; F1,58 = 6.973; P = .01; partial η(2) = .11). From 14 months before to 14 months after the bundle was implemented, the mean number of CLABSIs per LTACH decreased by 4.5 (95% CI, 1.85-7.15). Time series modeling showed a significant decrease in the mean hospital CLABSI rate after the bundle was implemented (-0.511 CLABSI/1000 catheter days, SE = 0.050), indicating an immediate effect of the bundle. The mean hospital CLABSI rate was decreasing slightly before the bundle was implemented and continued to decrease at a reduced rate after the bundle was implemented.

CONCLUSION

The bundle resulted in a significant and sustained reduction in CLABSI rates in 30 LTACHs for 14 months. These results encourage the development and implementation of similar bundles as effective strategies for infection reduction in LTACHs.

[Comparative study of complications related to the use of peripheral venous catheter with and without closed system with heparin cap]

Introduction

L'utilisation correcte du système clos à bouchon hépariné sur les cathéters périphériques pendant les perfusions est une pratique courante dans les pays développés et aussi dans plusieurs pays en développement selon un consensus international établi. Nous comparons les résultats de la formation de thrombus et de l'infection liées au cathéter veineux périphérique chez les patients ayant bénéficié de perfusion avec système clos à bouchon hépariné (groupe expérimentale) et ceux qui ont été perfusé sans bouchon hépariné (groupe témoin).

Méthodes

Nous avons colligé 100 patients hospitalisés pendant la période de Juillet 2014 à Décembre 2014 dans le service d'hospitalisation de chirurgie thoracique de l'hôpital du Mali qui ont été repartis en 2 groupes de 50 patients chacun pour une analyse comparative. L'observation du thrombus dans la lumière du cathéter est effectuée puis enregistré et tous les cathéters ont été repris pour réalisation de culture bactérienne au laboratoire dans les 2 groupes.

Résultats

Dans le groupe témoin, il existe un thrombus dans la lumière du cathéter dans 36 cas (72%) et l'examen de culture bactérienne était positif dans 90%. Tandis que dans le groupe expérimental on retrouve 3 cas (6%) de thrombose du cathéter et on note une absence de germe dans l'examen bactériologique.

Conclusion

L'utilisation correcte du système clos à bouchon hépariné lors des perfusions peut réduire et prévenir de façon significative les complications liées au cathéter notamment l'occlusion par thrombus, leur migration et la survenue de l'infection.

Getting to Zero: Goal Commitment to Reduce Blood Stream Infections

While preventing health care-associated infections (HAIs) can save lives and reduce health care costs, efforts designed to eliminate HAIs have had mixed results. Variability in contextual factors such as work culture and management practices has been suggested as a potential explanation for inconsistent results across organizations and interventions. We examine goal-setting as a factor contributing to program outcomes in eight hospitals focused on preventing central line-associated bloodstream infections (CLABSIs). We conducted qualitative case studies to compare higher- and lower-performing hospitals, and explored differences in contextual factors that might contribute to performance variation. We present a goal commitment framework that characterizes factors associated with successful CLABSI program outcomes. Across 194 key informant interviews, internal and external moderators and characteristics of the goal itself differentiated actors' goal commitment at higher- versus lower-performing hospitals. Our findings have implications for organizations struggling to prevent HAIs, as well as informing the broader goal commitment literature.

Reducing Oncology Unit Central Line-Associated Bloodstream Infections: Initial Results of a Simulation-Based Educational Intervention

PURPOSE

Patients with cancer may be more vulnerable to infection because of impaired immune competence as a result of their disease or chemotherapy-induced neutropenia. In these patients, central line-associated bloodstream infections (CLABSIs) can result in significant morbidity and mortality, prolonged hospitalization, and increased costs.

METHODS

We developed a staff educational series to identify knowledge deficits and standardize the use, care, and maintenance of central lines, with the goal of reducing the rate of CLABSIs. The methodology used for this study employed a simulated central line care model, focused on the re-education of nursing staff from January 2012 to June 2012, and included a pretest, an educational blitz, and a post-test. The educational blitz content was tailored to specifically address the significant practice and knowledge deficits identified from the results of the pretest.

RESULTS

On completion of the education program, the post-test demonstrated a 16.9% increase in nursing staff competence related to the care and maintenance of central lines. Six months before the educational series (June 2011 to January 2012), the CLABSI rate was 5.86 per 1,000 patient line-days. Throughout the educational series (February 2012 to May 2012), the CLABSI rate was 3.45. The data revealed a CLABSI rate of 3.43 for the 6-month period after the educational series (June 2012 to January 2013).

CONCLUSION

A targeted educational intervention using a simulated central line care model improved competence in central line care and resulted in decreased CLABSI rates for inpatient oncology patients.

Findings of the International Nosocomial Infection Control Consortium (INICC), Part III Effectiveness of a Multidimensional Infection Control Approach to Reduce Central Line—Associated Bloodstream Infections in the Neonatal Intensive Care Units of 4 Developing Countries

Objective.

To analyze the impact of the International Nosocomial Infection Control Consortium (INICC) multidimensional infection control approach to reduce central line-associated bloodstream infection (CLABSI) rates.

Setting.

Four neonatal intensive care units (NICUs) of INICC member hospitals from El Salvador, Mexico, Philippines, and Tunisia.

Patients.

A total of 2,241 patients hospitalized in 4 NICUs for 40,045 bed-days.

Methods.

We conducted a before-after prospective surveillance study. During Phase 1 we performed active surveillance, and during phase 2 the INICC multidimensional infection control approach was implemented, including the following practices: (1) central line care bundle, (2) education, (3) outcome surveillance, (4) process surveillance, (5) feedback of CLABSI rates, and (6) performance feedback of infection control practices. We compared CLABSI rates obtained during the 2 phases. We calculated crude stratified rates, and, using random-effects Poisson regression to allow for clustering by ICU, we calculated the incidence rate ratio (IRR) for each follow-up time period compared with the 3-month baseline.

Results.

During phase 1 we recorded 2,105 CL-days, and during phase 2 we recorded 17,117 CL-days. After implementation of the multidimensional approach, the CLABSI rate decreased by 55%, from 21.4 per 1,000 CL-days during phase 1 to 9.7 per 1,000 CL-days during phase 2 (rate ratio, 0.45 [95% confidence interval, 0.33–0.63]). The IRR was 0.53 during the 4–12-month period and 0.07 during the final period of the study (more than 45 months).

Conclusions.

Implementation of a multidimensional infection control approach was associated with a significant reduction in CLABSI rates in NICUs.

National Survey of Practices to Prevent Healthcare-Associated Infections in Thailand: The Role of Safely Culture and Collaboratives

Objective.

To evaluate hospital characteristics and practices used by Thai hospitals to prevent catheter-associated urinary tract infection (CAUTI), central line-associated bloodstream infection (CLABSI), and ventilator-associated pneumonia (VAP), the 3 most common types of healthcare-associated infection (HAI) in Thailand.

Design.

Survey.

Setting.

Thai hospitals with an intensive care unit and 250 or more hospital beds

Methods.

Between January 1, 2010, and October 31, 2010, research nurses collected data from all eligible hospitals. The survey assessed hospital characteristics and practices to prevent CAUTI, CLABSI, and VAP. Ordinal logistic regression was used to assess relationships between hospital characteristics and use of prevention practices.

Results.

A total of 204 (80%) of 256 hospitals responded. Most hospitals (93%) reported regularly using alcohol-based hand rub. The most frequently reported prevention practice by infection was as follows: for CAUTI, condom catheters in men (47%); for CLABSI, avoiding routine central venous catheter changes (85%); and for VAP, semirecumbent positioning (84%). Hospitals with peripherally inserted central catheter insertion teams were more likely to regularly use elements of the CLABSI prevention bundle. Greater safety scores were associated with regular use of several VAP prevention practices. The only hospital characteristic associated with increased use of at least 1 prevention practice for each infection was membership in an HAI collaborative.

Conclusions.

While reported adherence to hand hygiene was high, many of the prevention practices for CAUTI, CLABSI, and VAP were used infrequently in Thailand. Policies and interventions emphasizing specific infection prevention practices, establishing a strong institutional safety culture, and participating in collaboratives to prevent HAI may be beneficial.

Meta-analysis on central line-associated bloodstream infections associated with a needleless intravenous connector with a new engineering design

BACKGROUND

Intravenous needleless connectors (NCs) with a desired patient safety design may facilitate effective intravenous line care and reduce the risk for central line-associated bloodstream infection (CLA-BSI). We conducted a meta-analysis to determine the risk for CLA-BSI associated with the use of a new NC with an improved engineering design.

METHODS

We reviewed MEDLINE, Cochrane Database of Systematic Reviews, Embase, ClinicalTrials.gov, and studies presented in 2010-2012 at infection control and infectious diseases meetings. Studies reporting the CLA-BSIs in patients using the positive-displacement NC (study NC) compared with negative- or neutral-displacement NCs were analyzed. We estimated the relative risk of CLA-BSIs with the study NC for the pooled effect using the random effects method.

RESULTS

Seven studies met the inclusion criteria: 4 were conducted in intensive care units, 1 in a home health setting, and 2 in long-term acute care settings. In the comparator period, total central venous line (CL) days were 111,255; the CLA-BSI rate was 1.5 events per 1,000 CL days. In the study NC period, total CL days were 95,383; the CLA-BSI rate was 0.5 events per 1,000 CL days. The pooled CLA-BSI relative risk associated with the study NC was 0.37 (95% confidence interval, 0.16-0.90).

CONCLUSION

The NC with an improved engineering design is associated with lower CLA-BSI risk.

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.

National survey of suboptimal and unnecessary practices for central line placement and management in Thailand

We conducted a national survey among hospitals in Thailand regarding practices associated with central line placement and management. Results of the survey identified that both suboptimal and unnecessary practices are being conducted. Connectors and hubs were not disinfected before access (49%), multidose vial use (43%), and routine culture of catheter tips (21%). Physician leadership and designated catheter insertion teams were associated with less unnecessary or suboptimal reported practices.

Vessel health and preservation (Part 1): a new evidence-based approach to vascular access selection and management

Vascular access for the infusion of medications and solutions requires timely assessment, planning, insertion, and assessment. Traditional vascular access is reactive, painful, and ineffective, often resulting in the exhaustion of peripheral veins prior to consideration of other access options. Evidence suggests clinical pathways improve outcomes by reducing variations and establishing processes to assess and coordinate care, minimizing fragmentation and cost. Implementation of a vascular access clinical pathway leads to the intentional selection of the best vascular access device for the patient specific to the individual diagnosis, treatment plan, current medical condition, and the patient's vessel health (1). The Vessel Health and Preservation (VHP) programme incorporates evidence-based practices focused on timely, intentional proactive device selection implemented within 24 hours of admission into any acute facility. VHP is an all-inclusive clinical pathway, guiding clinicians from device selection through patient discharge, including daily assessment. Initiation of the VHP programme within a facility provides a systematic pathway to improve vascular access selection and patient care, allowing for the reduction of variations and roadblocks in care while increasing positive patient outcomes and satisfaction. Patient safety and preservation of vessel health is the ultimate goal.

Impact of a multidimensional infection control strategy on central line-associated bloodstream infection rates in pediatric intensive care units of five developing countries: findings of the International Nosocomial Infection Control Consortium (INICC)

PURPOSE

To analyze the impact of the International Nosocomial Infection Control Consortium (INICC) multidimensional infection control strategy including a practice bundle to reduce the rates of central line-associated bloodstream infection (CLAB) in patients hospitalized in pediatric intensive care units (PICUs) of hospitals, which are members of the INICC, from nine cities of five developing countries: Colombia, India, Mexico, Philippines, and Turkey.

METHODS

CLAB rates were determined by means of a prospective surveillance study conducted on 1,986 patients hospitalized in nine PICUs, over a period of 12,774 bed-days. The study was divided into two phases. During Phase 1 (baseline period), active surveillance was performed without the implementation of the multi-faceted approach. CLAB rates obtained in Phase 1 were compared with CLAB rates obtained in Phase 2 (intervention period), after implementation of the INICC multidimensional infection control program.

RESULTS

During Phase 1, 1,029 central line (CL) days were recorded, and during Phase 2, after implementing the CL care bundle and interventions, we recorded 3,861 CL days. The CLAB rate was 10.7 per 1,000 CL days in Phase 1, and in Phase 2, the CLAB rate decreased to 5.2 per 1,000 CL days (relative risk [RR] 0.48, 95% confidence interval [CI] 0.29-0.94, P = 0.02), showing a reduction of 52% in the CLAB rate.

CONCLUSIONS

This study shows that the implementation of a multidimensional infection control strategy was associated with a significant reduction in the CLAB rates in the PICUs of developing countries.
