The use of 3.15% chlorhexidine gluconate/70% alcohol hub disinfection to prevent central line-associated bloodstream infections in dialysis patients.

Preventing CLABSI events in the dialysis inpatient population represents significant challenges. Bacteremia associated with lines or grafts are common health-associated infections that lead to adverse patient outcomes. Dialysis patients represent a much higher infection risk due to health frequency needs, more frequent hospitalizations, multiple comorbidity issues, fistula functionality, and multiple attempts for line access leading to additional complications, costs, morbidity, and mortality. An observational study was conducted including central line device days, CLABSI events, and possible confounding variables in admitted dialysis patients. All CLABSI data were identified according to the Centers for Disease Control and Prevention's National Healthcare Safety Network's definitions for CLABSIs. The intervention involved the removal of 70% alcohol swabs and alcohol hub disinfecting caps, then replacing with swabs containing 3.15% chlorhexidine gluconate/70% alcohol for central line hub disinfection and vascular graft access skin disinfection. The 5-year preintervention period (2008-2012) involved 7568 central line days, 11 CLABSI events, and a 1.45 per 1000 device day rate. The 6-month trial period involved 1559 central line days and no CLABSI events. The 5-year postimplementation period (2013-2017) involved 9787 central line days, 5 CLABSI events, and a 0.51 per 1000 device day rate. The postimplementation period represented a statistically significant (P value=0.0493) reduction with 65% fewer CLABSI events compared with the preimplementation period. A limitation was variations in scrub time and dry time during central venous catheter hub access. While we were comparing 2 products, behavioral practices using these 2 products were possible influencers and represent a possible confounding variable. This study found that using alcohol with chlorhexidine gluconate prior to accessing central line hubs and vascular grafts allows for reduction in CLABSI events and sustains statistically significant lower CLABSI rates in the inpatient dialysis population. HIGHLIGHTS Using alcohol with chlorhexidine gluconate (CHG) before accessing central line hubs helps reduce central line-associated bloodstream infection (CLABSI) events Using alcohol with CHG before accessing vascular grafts helps reduce CLABSI events A statistically significant reduction (65%) in CLABSI events occurred after use. Statistically significant lower CLABSI rates are sustainable with use of alcohol with CHG.

An Interdisciplinary Team Decreases Hospital Acquired Infections in HCT Patients

Topic Significance & Study Purpose/Background/Rationale Prevention of healthcare-associated infections (HAI) is a priority of regulatory and national agencies and CMS implemented payment reductions for HAIs as of 2015. Central Line Associated Blood Stream Infections (CLABSI) in hospitalized patients are challenging HAIs that are known to increase lengths of stay, financial burdens, and overall mortality. HAI definitions are based on non-immunocompromised patient populations and immunocompromised patients often have increased reporting for these infections. Our NCCN hospital sought to better describe CLABSIs in our hematopoietic cell transplant (HCT) population to assure appropriate reporting of HAIs and to identify opportunities for quality improvement. Methods, Intervention, & Analysis An interdisciplinary team including the Infection Prevention Medical Director, Infection Preventionists and Physicians, Pharmacist, inpatient Nurse Manager and a Clinical Nurse Specialist met monthly to perform intensive reviews of CLABSI events that occurred on an inpatient HCT unit. The review included patient risk factors for infection and the degree to which nurses followed the central line care bundle. As a result of these reviews, a Staff RN group was formed who were educated to became unit experts on CLABSI and central line care. Subsequently, CLABSI rates reduced by 30%. Findings & Interpretation CLABSI reviews found common organisms across cases, opportunities for improvement in nursing practice as well as trends in patient characteristics where gaps in care may exist. By expanding these reviews to other HAIs, situations where standard definitions may not directly apply were identified, particularly with Clostridium Difficile Infection (CDI). The interdisciplinary CDI review focused on common causes of diarrhea which were then categorized and shared with staff to aid in patient care decisions. Discussion & Implications Intensive review of HAI events and identification of trends in the immunocompromised patient population assures accurate reporting of these cases. Reviews also allow for development of internal classifications of causes and ongoing process improvement in patient care by identifying unique situations leading to those infections. While this process requires resources to perform data collection and to review cases, the subsequent potential improvement in patient care may offset those. Multidisciplinary case review can help to improve practice, decrease infections, and potentially decrease the cost of patient care.

Impact of Repeat Infection Timeframe on CLABSI Surveillance

BACKGROUND Mandatory reporting of central line-associated bloodstream infections (CLABSIs) to the National Healthcare Safety Network (NHSN) is used as a measure of healthcare quality and hospital reimbursement. State reporting laws mandate patient notification of each healthcare associated infection. In January 2015, NHSN updated surveillance procedures to include the implementation of the 14-day repeat infection timeframe (RIT), to clarify the definition of resolved versus continued infection. We describe the impact of the RIT on CLABSI surveillance at an academic, quaternary care pediatric hospital. METHODS We performed a retrospective, cohort evaluation of existing hospital surveillance data to identify repeat CLABSIs occurring within the first seven days after the CLABSI RIT from January 2015 to July 2018. Repeat CLABSI events were considered unresolved infections when the microorganisms grown were identical or closely related to those grown at onset or during the first 5 days of the index CLABSI. Characteristics of repeat CLABSI events were described and compared to all CLABSIs using Fisher's exact test. RESULTS We identified 13 new CLABSI events that occurred within seven days of the previous CLABSI's RIT (day 15-21). Seven of these CLABSIs were considered unresolved infections. The remaining 6 CLABSIs involved different microorganisms than identified at onset of the initial CLABSI. There was no difference in clinical service (p=0.89), patient immune status (p=0.25), line type (p=0.69), or presence of multiple central lines (p=0.27) when comparing unresolved CLABSIs (n=7) to the total number of CLABSIs identified during the time period (n=389). Conversely, 4 CLABSIs had new microorganisms added during the RIT that were not reported as a unique event. CONCLUSIONS The use of the RIT does not always appropriately identify new CLABSIs at our institution. Since CLABSI identification is used for improvement efforts, modification of the RIT may be needed to properly identify unique CLABSIs.

Central Line-Associated Bloodstream Infections in Children With Hematologic and Oncologic Diseases: First Prevalence Results From a University Hospital.

Central line-associated bloodstream infections (CLABSIs) are still a major cause of morbidity and mortality in pediatric hematology-oncology patients in many countries. This cross-sectional study was a retrospective review of CLABSI in inpatient pediatric hematology-oncology cases with long-term central venous catheter at the Pediatric Hematology Department from January 2013 to June 2014. Characteristics of CLABSI events in pediatric patients with hematologic malignancies and related nonmalignant hematologic conditions are documented. CLABSI developed in 61.8% (n = 21) of the 34 hospitalized patients included in the study. The CLABSI rate was 7.8 per 1,000 inpatient central venous catheter days. Coagulase-negative staphylococci was the predominant pathogen in 47.6% of the patients with CLABSI. The high rate of CLABSI requires prevention strategies to reduce CLABSI immediately. This study provides guidance in prioritizing strategies for reducing rates of infection.

Central line-associated bloodstream infection among children with biliary atresia listed for liver transplantation.

BACKGROUNDPre-transplant nutrition is a key driver of outcomes following liver transplantation in children. Patients with biliary atresia (BA) may have difficulty achieving satisfactory weight gain with enteral nutrition alone, and parenteral nutrition (PN) may be indicated. While PN has been shown to improve anthropometric parameters of children with BA listed for liver transplantation, less is known about the risks, particularly infectious, associated with this therapy among this specific group of patients.AIMTo describe the incidence, microbiology, and risk factors of central line-associated bloodstream infection (CLABSI) among children with BA listed for liver transplantation.METHODSRetrospective review of children aged ≤ 2-years of age with BA who were listed for primary liver transplantation at Texas Children’s Hospital from 2008 through 2015 (n = 96). Patients with a central line for administration of PN (n = 63) were identified and details of each CLABSI event were abstracted. We compared the group of patients who experienced CLABSI to the group who did not, to determine whether demographic, clinical, or laboratory factors correlated with development of CLABSI.RESULTSNineteen of 63 patients (30%, 95%CI: 19, 43) experienced 29 episodes of CLABSI during 4800 line days (6.04 CLABSI per 1000 line days). CLABSI was predominantly associated with Gram-negative organisms (14/29 episodes, 48%) including Klebsiella spp., Enterobacter spp., and Escherichia coli. The sole polymicrobial infection grew Enterobacter cloacae and Klebsiella pneumoniae. Gram-positive organisms (all Staphylococcus spp.) and fungus (all Candida spp.) comprised 9/29 (31%) and 6/29 (21%) episodes, respectively. No demographic, clinical, or laboratory factors were significantly associated with an increased risk for the first CLABSI event in Cox proportional hazards regression analysisCONCLUSIONThere is substantial risk for CLABSI among children with BA listed for liver transplantation. No clinical, demographic, or laboratory factor we tested emerged as an independent predictor of CLABSI. While our data did not show an impact of CLABSI on the short-term clinical outcome, it would seem prudent to implement CLABSI reduction strategies in this population to the extent that each CLABSI event represents potentially preventable hospitalization, unnecessary healthcare dollar expenditures, and may exact an opportunity cost, in terms of missed allograft offers.

Decreasing dialysis catheter rates by creating a multidisciplinary dialysis access program

Centers for Medicare and Medicaid Services have determined that chronic dialysis units should have <12% of their patients utilizing central venous catheters for hemodialysis treatments. On the Eastern Shore of Maryland, the central venous catheter rates in the dialysis units averaged >45%. A multidisciplinary program was established with goals of decreasing catheter rates in order to decrease central line-associated bloodstream infections, decrease mortality associated with central line-associated bloodstream infection, decrease hospital days, and provide savings to the healthcare system. We collected the catheter rates within three dialysis centers served over a 5-year period. Using published data surrounding the incidence and related costs of central line-associated bloodstream infection and mortality per catheter day, the number of central line-associated bloodstream infection events, the costs, and the related mortality could be determined prior to and after the initiation of the dialysis access program. An organized dialysis access program resulted in a 82% decrease in the number of central venous catheter days which lead to a concurrent reduction in central line-associated bloodstream infection and deaths. As a result of creating an access program, central venous catheter rates decreased from an average rate of 45% to 8%. The cost savings related to the program was calculated to be over US$5 million. The decrease in the number of mortalities is estimated to be between 13 and 27 patients. We conclude that a formalized access program decreases catheter rates, central line-associated bloodstream infection, and the resultant hospitalizations, mortality, and costs. Areas with high hemodialysis catheter rates should develop access programs to better serve their patient population.

Reduction in Central Line-Associated Bloodstream Infections in a NICU: Practical Lessons for Its Achievement and Sustainability.

Central venous catheters are commonly used for the provision of parenteral nutrition and medications for critically ill neonates in the NICU. However, central line-associated bloodstream infections (CLABSIs) are a major complication associated with their use and remain an important cause of nosocomial sepsis in NICUs. Central line-associated bloodstream infection has shifted from being an expected routine complication of central line use to an adverse event now evaluated as a critical event with the goal of identifying root causes so future CLABSI events are prevented. Success has been achieved through multiple strategies including implementation and maintenance of care bundles, education strategies to promote consistent adherence to bundle components, and institutional and unit support. Although low CLABSI rates can be achieved, sustaining low CLABSI rates and achieving zero CLABSI remain an ongoing challenge. We describe our experience with lessons learned, with an emphasis on the areas of difficulty during implementation of the bundle elements and the strategies and tools we utilized to overcome them.

Two-Year Hospital-Wide Surveillance of Central Line-Associated Bloodstream Infections in a Korean Hospital.

BackgroundSurveillance and interventions of central line-associated bloodstream infections (CLABSIs) had mainly been targeted in intensive care units (ICUs). Central lines are increasingly used outside ICUs. Therefore, we performed a hospital-wide survey of CLABSIs to evaluate the current status and develop strategies to reduce CLBASI rates.MethodsAll hospitalized patients with central venous catheters (CVCs) were screened for CLABSIs from January 2014 through December 2015 at a 1,328 bed tertiary care teaching hospital in Korea using an electronic data-collecting system. Clinical information including type of CVC was collected. CLABSI rates were calculated using the definitions of the National Health and Safety Network after excluding mucosal barrier injury laboratory-confirmed bloodstream infection (BSI).ResultsA total of 154 CLABSIs were identified, of which 72 (46.8%) occurred in general wards and 82 (53.2%) in ICUs (0.81 and 2.71 per 1,000 catheter days), respectively. Non-tunneled CVCs were most common (68.6%) among 70 CLABSI events diagnosed within one week of their maintenance. On the other hand, tunneled CVCs and peripherally inserted central catheters (PICCs) were more common (60.5%) among 114 CLABSI events diagnosed more than a week after maintenance. Whereas the majority (72.2%) of CLABSIs in ICUs were associated with non-tunneled CVCs, tunneled CVCs (38.9%) and PICCs (36.8%) were more common in general wards.ConclusionCLABSIs are less common in general wards than in ICUs, but they are more often associated with long-term indwelling catheters. Therefore, interventions to prevent CLABSIs should be tailored according to the type of ward and type of catheter.

A3 for Central Line-Associated Blood Stream Infections

SESSION TITLE: Quality Improvement 1 SESSION TYPE: Original Investigation Poster PRESENTED ON: Wednesday, November 1, 2017 at 01:30 PM - 02:30 PM PURPOSE: An estimated 30,000 central line associated blood stream infections (CLABSIs) occur in U.S. Intensive Care Units (ICUs) each year. Patient mortality rates associated with CLABSI range from 12-25% and the cost of CLABSIs ranges from $3,700 to $36,000 per episode of care. To address this issue, we collaborated with hospital management to create a multidisciplinary team to enhance the care of patients with central venous catheters (CVCs) by using A3. A3 is a problem solving and continuous improvement approach first employed by Toyota and based on Edward Denning’s PDSA (Plan-Do-Study-Act).We implemented an A3 problem solving methodology in order to systematically reduce CLABSI among the medical and surgical ICUs. METHODS: A review of CLABSI related events across the various adult ICUs was performed. Initial and target states were established. The goal was to achieve a zero CLABSI rate by standardizing workflow for insertion, implementing strict guidelines for maintenance, and emphasizing early removal of CVCs. Gap analysis was used to identify multiple areas for improvement, which fell into five major categories: workflow, education, documentation, assessment and visual management. During subsequent monthly meetings, multiple small experiments were developed and implemented. Some of the products of these experiments include the creation of standardized central line insertion and maintenance checklists, a CVC insertion and maintenance audit tool, and a decision algorithm for line insertion and maintenance. RESULTS: We reviewed a total of 14,960 ICU patient days. Mean patient-days per month was 298 (range 210-379). Following the implementation of insertion and maintenance checklists in ICUs, we were able bring down our CLABSI Rate (CLABSI events /1000 patient days) from 2.25 to 0.00 to achieve our target goal of zero. CLABSI rates were reduced by 100% among adult ICU patients (p<0.001). Despite emphasis to reduce the use of central lines by early removal and consideration of alternative access, the device utilization ratio (defined as device utilization days divided by patient days) remained relatively constant (mean 0.30; range 0.23-0.39). These rates were sustained over the next nine months and checklists are permanently embedded in ICU work protocol. CONCLUSIONS: Our data demonstrates the effectiveness of the A3 approach for improving quality and safety among the different ICUs. Using this methodology, we were able to serially introduce several interventions that acted synergistically to eliminate CLABSI in the ICU. CLINICAL IMPLICATIONS: A3 provides an effective appraoch to problem solving and can be used in clinical setting to decrease and sustain lower CLABSI rates.

Central-line-associated bloodstream infections in a resource-limited South African neonatal intensive care unit.

The rate of central-line-associated bloodstream infection (CLABSI) in South African (SA) public sector neonatal intensive care units (NICUs) is unknown. Tygerberg Children's Hospital (TCH), Cape Town, introduced a neonatal CLABSI surveillance and prevention programme in August 2012. To describe CLABSI events and identify risk factors for development of CLABSI in a resource-limited NICU. A retrospective case-control study was conducted using prospectively collected NICU CLABSI events matched to four randomly selected controls, sampled from the NICU registry between 9 August 2012 and 31 July 2014. Clinical data and laboratory records were reviewed to identify possible risk factors, using stepwise forward logistic regression analysis. A total of 706 central lines were inserted in 530 neonates during the study period. Nineteen CLABSI events were identified, with a CLABSI rate of 5.9/1 000 line days. CLABSI patients were of lower gestational age (28 v. 34 weeks; p=0.003), lower median birth weight (1 170 g v. 1 975 g; p=0.014), had longer catheter dwell times (&gt;4 days) (odds ratio (OR) 5.1 (95% confidence interval (CI) 1.0 - 25.4);p=0.04) and were more likely to have had surgery during their NICU stay (OR 3.5 (95% CI 1.26 - 10); p=0.01). Significant risk factors for CLABSI were length of stay &gt;30 days (OR 20.7 (95% CI 2.1 - 203.2); p=0.009) and central-line insertion in the operating theatre (OR 8.1 (95% CI 1.2 - 54.7); p=0.03). Gram-negative pathogens predominated (12/22; 54%), with most isolates (10/12; 83%) exhibiting multidrug resistance. The TCH NICU CLABSI rate is similar to that reported from resource-limited settings, but exceeds that of high-income countries. Prolonged NICU stay and central-line insertion in the operating theatre were important risk factors for CLABSI development. Intensified neonatal staff training regarding CLABSI maintenance bundle elements and hand hygiene are key to reducing CLABSI rates.

A quality assurance investigation of CLABSI events: are there exceptions to never?

In the USA, central line associated blood stream infections (CLABSIs) have been designated as 'never events', prompting initiatives towards a 'zero CLABSIs' standard. We propose that there are cascading risk factors predisposing certain patient cohorts to higher CLABSIs rates. A retrospective review of all CLABSI infections over a 12-month period was undertaken. Risk factors examined included catheter type, insertion site and parenteral nutrition (PN) status. Additional factors analysed included acute kidney injury (AKI), chronic kidney disease (CKD) and hospital-acquired infections (HAIs). Thirty-four CLABSIs were identified in 33 adult patients (median age = 57 years). Temporary central venous catheters accounted for 12 (35%), peripherally inserted central catheters for five (14.7%), and permanent catheters for 17 CLABSIs (50%); the median duration from insertion was 15 days (interquartile range = 9-26). Among patient factors, immunosuppression and hyperglycaemia were the most common (n = 19, 55%), followed by PN and CKD (n = 17, 50.0%), AKI (n = 16, 47.1%) and HAIs (n = 13, 38.2%). A majority of patients with CLABSIs (n = 20 58.8%) had at least three risk factors. These findings reflect the complexity of CLABSIs with multiple patient and hospital factors influencing incidence. It suggests the need for further studies to re-calibrate the zero CLABSI model towards one with greater relevance.

Definitional Change in NHSN CAUTI Was Associated with an Increase in CLABSI Events: Evaluation of a Large Health System

BACKGROUND The National Healthcare Safety Network (NHSN) catheter-associated urinary tract infection (CAUTI) definition was revised as of January 2015 to exclude funguria and lower bacteriuria levels. We evaluated the effect of the CAUTI definition change on NHSN-defined central-line-associated bloodstream infection (CLABSI) outcomes. METHODS We compared CAUTI and CLABSI NHSN-defined outcomes for calendar years 2014 and 2015 in the adult intensive care units (ICUs) of a single large health system. Changes in the event rates, the associated organisms, and the standardized infection ratio (SIR) were evaluated. RESULTS The study included 137 adult ICUs from 65 hospitals. The CAUTI SIR dropped from 1.04 in 2014 to 0.58 in 2015 (-44.2%), while the CLABSI SIR increased from 0.36 in 2014 to 0.47 in 2015 (+30.6%). CAUTI rates dropped 44.8% from 2.09 to 1.15 events per 1,000 device days (P<.001). Gram-positive-associated CAUTI rates dropped 36.7% from 0.34 to 0.22 per 1,000 device days (P=.007). CLABSI rates increased 27.1% from 0.71 to 0.90 per 1,000 device days (P=.027). Candida-associated CLABSI increased by 91.1% from 0.104 to 0.198 per 1,000 device days (P=.012), and Enterococcus-associated CLABSI increased by 121.6% from 0.071 to 0.16 per 1,000 device days (P=.008). CONCLUSIONS The revised CAUTI definition led to a large reduction in CAUTI rates and, in turn, an increase in candidemia and enterococcemia cases classified as CLABSI events. These findings have important implications on the perceived successes or failures to eliminate both infections. Infect Control Hosp Epidemiol 2017;38:685-689.

A Sample Toolkit for Teaching Vascular Access to Undergraduate Nursing Students

This study was done to describe the incidence and outcomes of primary hospital-acquired bloodstream infection (HABSI) secondary to Staphylococcus aureus (SA) that did and did not meet the National Healthcare Safety Network's (NHSN's) definition for central line–associated bloodstream infection (CLABSI).Consecutive hospitalized patients during a 48-month study period with an SA HABSI were categorized according to those who did and did not meet the NHSN's definitions for CLABSI and non-CLABSI. Primary outcomes were mortality at 30 days and 1 year. Secondary outcomes were the incidence of complicated bacteremia and the need for operative intervention secondary to the HABSI event.A total of 122 episodes of primary SA HABSIs were identified: 78 (64%) were CLABSIs, and 44 (36%) were non-CLABSIs. Overall 30-day and 1-year mortality in the cohort was 21.3% and 38.5%, respectively, and did not differ significantly between the 2 groups. Complicated SA HABSI was significantly more common in the non-CLABSI group (15.9% [n = 7] vs 0% [n = 0], P ≤ .001).Primary SA HABSI was associated with significant 30-day and 1-year mortality. Complications from SA non-CLABSI requiring surgical intervention were significantly more common than in those with a CLABSI event. Our findings affirm the significance of non–device-related hospital-acquired infections.

Central venous catheter infections in home parenteral nutrition patients: Outcomes from Sustain: American Society for Parenteral and Enteral Nutrition's National Patient Registry for Nutrition Care.

Home parenteral nutrition (HPN) is a high-cost, complex nutrition support therapy that requires the use of central venous catheters. Central line-associated bloodstream infections (CLABSIs) are among the most serious risks of this therapy. Sustain: American Society for Parenteral and Enteral Nutrition's National Patient Registry for Nutrition Care (Sustain registry) provides the most current and comprehensive data for studying CLABSI among a national cohort of HPN patients in the United States. This is the first Sustain registry report detailing longitudinal data on CLABSI among HPN patients. To describe CLABSI rates for HPN patients followed in the Sustain registry from 2011-2014. Descriptive, χ2, and t tests were used to analyze data from the Sustain registry. Of the 1,046 HPN patients from 29 sites across the United States, 112 (10.7%) experienced 194 CLABSI events during 223,493 days of HPN exposure, for an overall CLABSI rate of 0.87 episodes/1,000 parenteral nutrition-days. Although the majority of patients were female (59%), adult (87%), white (75%), and with private insurance or Medicare (69%), CLABSI episodes per 1,000 parenteral nutrition-days were higher for men (0.69 vs 0.38), children (1.17 vs 0.35), blacks (0.91 vs 0.41), and Medicaid recipients (1.0 vs 0.38 or 0.39). Patients with implanted ports or double-lumen catheters also had more CLABSIs than those with peripherally inserted or central catheters or single-lumen catheters. Staphylococci were the most commonly reported pathogens. These data support findings of smaller studies about CLABSI risk for children and by catheter type and identify new potential risk factors, including gender, race, and insurance type. Additional studies are needed to determine effective interventions that will reduce HPN-associated CLABSI.

One Rural Hospital's Experience Implementing the Society for Healthcare Epidemiology of America Guidelines to Decrease Central Line Infections

In an effort to take advantage of the Highmark Quality Blue Initiative () requiring information from hospitals detailing their central line-associated blood stream infections (CLABSIs) surveillance system, quality improvement program, and statistics regarding the CLABSI events, this institution investigated the latest evidence-based recommendations to reduce CLABSIs. Recognizing the baseline rate of 2.4 CLABSIs per 1,000 central line days and its effect on patient outcomes and medical costs, this hospital made a commitment to improve their CLABSI outcomes. As a result, the facility adopted the Society for Healthcare Epidemiology of America (SHEA) guidelines. The purpose of this article is to review the CLABSI rates and examine the prevention strategies following implementation of the SHEA guidelines. A quantitative, descriptive retrospective program evaluation examined the hospital's pre- and post-SHEA implementation methods of decreasing CLABSIs and the subsequent CLABSI rates over 3 time periods. Any patient with a CLABSI infection admitted to this hospital July 2007 to June 2010 (N = 78). CLABSI rates decreased from 1.9 to 1.3 over the study period. Compliance with specific SHEA guidelines was evaluated and measures were put into place to increase compliance where necessary. CLABSI rates at this facility remain below the baseline of 2.4 for calendar year 2013 (0.79), 2014 (0.07), and 2015 (0.33).

A project to reduce the rate of central line associated bloodstream infection in ICU patients to a target of zero

Central Line Associated Blood Stream Infections in Pediatric Hematology/Oncology Patients With Different Types of Central Lines.

Central line associated bloodstream infections (CLABSIs) are a significant cause of morbidity and mortality in pediatric hematology/oncology (PHO) patients. Understanding the differences in CLABSI rates by central line (CL) type is important to inform clinical decisions. CLABSI, using similar definitions, noted with three commonly used CL types (totally implanted catheter [port], tunneled externalized catheter [TEC], peripherally inserted central catheter [PICC]) and CL-specific line days were prospectively tracked across 15 US PHO centers from May 2012 until April 2015 and CLABSI rates (CLABSI per 1,000 CL-specific line days) were calculated. Host and organism characterstics associated with the CLABSI events were analyzed. Over the course of 2.8 million line days, 1,113 CLABSI events (397 in inpatients and 716 in ambulatory patients) were noted. The inpatient CLABSI rate was higher than the ambulatory CLABSI rate for each of the CL types: 1.48 versus 0.16 for ports, 3.51 versus 1.38 for TECs, and 3.07 versus 1.16 for PICCs, respectively. TECs and PICCs were associated with higher CLABSI rates than ports, inpatient and ambulatory. We found that CLABSI rates were significantly higher for inpatients compared to ambulatory PHO patients for all CL types. Among ambulatory patients, TECs had the highest CLABSI rate and ports the lowest. Among inpatients, TECs and PICCs had higher CLABSI rates than ports but were not statistically different from one another. Cognizant that host and underlying disease attributes may contribute to these differences, these results can still inform CL choice in clinical practice.

Hospital-acquired Staphylococcus aureus primary bloodstream infection: A comparison of events that do and do not meet the central line–associated bloodstream infection definition

This study was done to describe the incidence and outcomes of primary hospital-acquired bloodstream infection (HABSI) secondary to Staphylococcus aureus (SA) that did and did not meet the National Healthcare Safety Network's (NHSN's) definition for central line-associated bloodstream infection (CLABSI). Consecutive hospitalized patients during a 48-month study period with an SA HABSI were categorized according to those who did and did not meet the NHSN's definitions for CLABSI and non-CLABSI. Primary outcomes were mortality at 30 days and 1 year. Secondary outcomes were the incidence of complicated bacteremia and the need for operative intervention secondary to the HABSI event. A total of 122 episodes of primary SA HABSIs were identified: 78 (64%) were CLABSIs, and 44 (36%) were non-CLABSIs. Overall 30-day and 1-year mortality in the cohort was 21.3% and 38.5%, respectively, and did not differ significantly between the 2 groups. Complicated SA HABSI was significantly more common in the non-CLABSI group (15.9% [n = 7] vs 0% [n = 0], P ≤ .001). Primary SA HABSI was associated with significant 30-day and 1-year mortality. Complications from SA non-CLABSI requiring surgical intervention were significantly more common than in those with a CLABSI event. Our findings affirm the significance of non-device-related hospital-acquired infections.

Risk Factors for Central Venous Catheter-Associated Bloodstream Infection in Pediatric Patients: A Cohort Study.

OBJECTIVE To examine the incidence of central-line-associated bloodstream infection (CLABSI) over time and to determine risk factors for CLABSI in hospitalized children. DESIGN Prospective cohort study. SETTING Pediatric tertiary care referral center in Halifax, Nova Scotia, serving a population of 2.3 million. PARTICIPANTS Patients ages 0-18 years with central venous catheters (CVCs) inserted at this facility between 1995 and 2013. METHODS Participants were followed from CVC insertion to CLABSI event or until CVC removal. Data were prospectively collected by clinicians, infection prevention and control staff, and nursing staff for the purposes of patient care, surveillance, and quality improvement. Cox proportional hazards regression was used to identify risk factors for CLABSI. RESULTS Among 5,648 patients, 385 developed CLABSI (0.74 CLABSI per 1,000 line days; or 3.87 per 1,000 in-hospital line days). Most infections occurred within 60 days of insertion. CLABSI rates decreased from 4.87 per 1,000 in-hospital line days in 1995 to 0.78 per 1,000 in-hospital line days in 2013, corresponding to an 84% reduction. A temporal association of CLABSI reduction with a hand hygiene promotion campaign was identified. CVC type, number of lumens, dressing type, insertion vein, and being in the critical care unit were statistically significantly associated with CLABSI. CONCLUSIONS Hospital-wide surveillance over an 18-year period identified children at highest risk for CLABSI and decreasing risk over time; this decrease was temporally associated with a hand hygiene campaign.

Burden of bloodstream infections among ambulatory pediatric hematology/oncology patients with a central line.

262 Background: Pediatric hematology/oncology (PHO) patients are at high risk of bloodstream infections (BSI). The burden of BSI in PHO patients in the ambulatory setting has not been well documented. Methods: The Children’s Hospital Association leads the Childhood Cancer and Blood Disorders Network, a multicenter United States quality improvement collaborative, working to reduce the incidence of inpatient and ambulatory Central Line-Associated BSI (CLABSI) among PHO patients. Positive blood culture events (+BCE) were adjudicated as CLABSI, single positive blood cultures (SPBC) with potential commensals, or secondary BSI (attributed to source other than the central line) following standardized National Healthcare Safety Network definitions. Our study investigated the prevalence of +BCE among all centers with 90% complete monthly reporting of both +BCE and central line days (CLD) for at least one year (n=25) between January 2012 and September 2014. Ambulatory and inpatient BSI rates and 95% confidence intervals (CI) were calculated as the number of +BCE per 1,000 CLD per month. Results: A total of 1,747 +BCE and 4,883,413 CLD were reported among our target ambulatory population, whereas 1,095 +BCE and 353,259 CLD were reported among our corresponding inpatient population [Table]. While the CLABSI and SPBC rates were significantly lower in the ambulatory setting compared to inpatient (p&lt;0.001), the total number of ambulatory CLABSI and SPBC events was 2.0 and 1.6 times higher than inpatient events, respectively. Conclusions: Our findings from a large multicenter collaborative demonstrate the burden of BSI among ambulatory PHO patients and identify benchmarks for future quality improvement work.Further investigation is necessary to develop effective infection reduction strategies for ambulatory PHO patients with central lines.
