Abstract Background Positive peripheral blood culture results are essential in guiding antimicrobial therapy in patients with bacteremia. However, false-positive results may frequently pose diagnostic issues in interpreting the test. These results can lead to increased costs and patient harm through the administration of unnecessary antibiotics and prolongation of hospital stay. The maximum acceptable contamination rate for peripheral blood cultures as suggested by the College of American Pathologists is 3%. Methods We initiated a longitudinal quality improvement project to monitor peripheral blood contamination rates at our children’s hospital in Brooklyn, NY. We reviewed positive blood culture results on a monthly basis and assessed whether they represented true infections vs. contamination based on review of patient charts. Residents and nurses in the pediatric emergency department (ED), neonatal intensive care unit (NICU), pediatric intensive care unit (PICU), inpatient unit, and newborn nursery were educated on proper skin sterilization techniques using video demonstration; the importance of avoiding palpating the venipuncture site after sterilization and the importance of cleaning the port on the blood culture bottle were reinforced. Results The pediatric ED and the PICU had the highest contamination rates in 2018 at 4.38% and 3.82%, respectively. The newborn nursery had the lowest contamination rate, at 0%. The NICU and pediatric inpatient units had contamination rates that met the goal as well, at 1.25% and 0.72%, respectively. Conclusion The departments in need of targeted interventions are the pediatric ED and the PICU, both of which had contamination rates greater than the 3% goal rate set for our project. Future interventions currently being considered include re-education of nursing and resident staff as well as the creation of equipment bundles to facilitate adequate skin preparation prior to venipuncture.

AbstractObjective:To describe the epidemiologic and molecular investigations that successfully contained an outbreak of methicillin-resistant Staphylococcus aureus (MRSA) in a neonatal intensive care unit (NICU).Design:Isolates of MRSA were typed by pulsed-field gel electrophoresis (PFGE) and S. aureus protein A (spa).Setting:A level III-IV, 45-bed NICU located in a children's hospital within a medical center.Patients:Incident cases had MRSA isolated from clinical cultures (eg, blood) or surveillance cultures (ie, anterior nares).Interventions:Infected and colonized infants were placed on contact precautions, cohorted, and treated with mupirocin. Surveillance cultures were performed for healthcare workers (HCWs). Colonized HCWs were treated with topical mupirocin and hexachlorophene showers.Results:From January to March 2001, the outbreak strain of MRSA PFGE clone B, was harbored by 13 infants. Three (1.3%) of 235 HCWs were colonized with MRSA. Two HCWs, who rotated between the adult and the pediatric facility, harbored clone C. One HCW, who exclusively worked in the children's hospital, was colonized with clone B. From January 1999 to November 2000, 22 patients hospitalized in the adult facility were infected or colonized with clone B. Spa typing and PFGE yielded concordant results. PFGE clone B was identified as spa type 16, associated with outbreaks in Brazil and Hungary.Conclusions:A possible route of MRSA transmission was elucidated by molecular typing. MRSA appears to have been transferred from our adult facility to our pediatric facility by a rotating HCW. Spa typing allowed comparison of our institution's MRSA strains with previously characterized outbreak clones.

Measure Blood Pressure

Arterial lines with three-way taps are used to measure blood pressure and aspirate blood, and are a potential source of catheter-related sepsis. Swabs were taken daily from 118 three-way taps on 98 arterial lines in a general intensive care unit. Infusion lines were changed weekly but arterial cannulae were not changed routinely. An overall contamination rate of 24.6% was found with the predominant organism being coagulase negative staphylococcus. The three-way taps became increasingly contaminated with time but this was shown to be unrelated to the manipulation rates. Blood culture organisms in those showing contamination of the three-way taps showed no relationship to the bacteria causing the contamination.

Research was carried out at the paediatric intensive care unit (paediatric ICU) of the  Children’s Hospital, affiliate of Vilnius University Hospital Santariškių klinikos. Background. Being the most common cause of children’s death, sepsis is a challenge for most physicians. In order to improve the outcomes, it is important to know the aetiology and peculiarities of sepsis in a particular region and hospital. The aim of this study was to analyse the outcomes of sepsis in a paediatric intensive care unit and their relation with patients’ characteristics and causative microorganisms. Materials and Methods. A retrospective analysis of the Sepsis Registration System in Vilnius University Children’s hospital was started in 2012. From 2012 to 2015, we found 529 sepsis cases in our hospital, 203 of which were found to be fulfilling all of the inclusion criteria (patient’s age >28 days on admission, taken blood culture/positive PCR test, need for paediatric ICU hospitalization) and were included in the final analysis. Abbreviations: ICD – international disease classification PCR – polymerase chain reaction Results. Sepsis made 4% of all patients of the paediatric ICU in the period from 2012 to 2015 and caused 32% of deaths in the unit. Paediatric mortality reached 14% of all sepsis cases in our analysis, the majority of them due to hospital-acquired sepsis that occurred in patients suffering from oncologic or hematologic diseases. Another significant part of the patients that did not survive were previously healthy with no co-morbidities. The  most common microorganism in lethal community-acquired cases was N. meningitidis and in hospital-acquired sepsis – Staphylococcus spp. Multi-drug resistance was observed, especially in the cases of hospital-acquired sepsis. Conclusions. A large percentage of lethal outcomes that occur in the paediatric ICU are due to sepsis. The majority of lethal cases of sepsis occur in patients suffering from chronic co-morbidities, such as oncologic, hematologic, neurologic, and others.

Abstract Abstract 4341 Background: Transfusion services must offer means of issuing blood products quickly for emergent transfusions. At Lucile Packard Children’s Hospital (LPCH), off-site refrigerators were installed in the Neonatal Intensive Care Unit (NICU), the LPCH operating room (OR) and the Cardiovascular Intensive Care Unit (CVICU) inventoried with uncrossmatched O negative RBCs for immediate emergency use. Uncrossmatched O negative RBCs are also provided to children undergoing cardiac catheterization at the discretion of the Pediatric Cardiologist, since these patients commonly do not have type and screen samples drawn until large vessel venous cannulation via insertion of the catheter. Uncrossmatched blood products are also provided for children per our massive transfusion protocol (MTP). The purpose of this study was to assess the utilization of these uncrossmatched blood products in children and its impact on transfusion service (TS) inventory of O negative RBCs. Methods: Orders received for emergency-release uncrossmatched RBCs for patients ages 0 days to 18 years including MTPs from January 1 2011 to March 31 2011 were evaluated retrospectively. Variables collected include: patient demographic information and diagnosis; blood products ordered, released and transfused; location of the patient and location from where blood was dispensed (off-site refrigerator versus [vs] TS). Results: Median patient age was 3.46 years (range 0 days to 15.62 years), and 82% of the patients had congenital heart disease. Sixty four RBCs were issued to 33 patients during the 3-month study period. Of those, 32 RBCs were transfused, 8 RBCs were wasted because temperature parameters were exceeded before return to the TS, and 24 RBCs (38%) were not transfused and returned to TS inventory. Nineteen of the 32 RBCs were transfused, representing 2% of the total 964 O negative RBC units transfused at our institution for that time period. Nineteen (58%) units were for children in the cardiac catheterization suite. Seven patients were in the CVICU, five children were in the NICU, and two were in the Pediatric Intensive Care Unit. Two units of O negative RBCs were dispensed from the emergency off-site refrigerator in the CVICU. Discussion: The majority of children (79%) who received emergency-release uncrossmatched O negative RBCs at LPCH were those with congenital heart disease undergoing cardiac catheterization or being cared for post-operatively in the CVICU. There were 2 instances of children requiring RBCs from off-site refrigerators for an emergent transfusion. Emergency-release, uncrossmatched O negative RBCs at LPCH either from the TS or from three off-site refrigerators caused no undue strain on our supply and inventory of donor O negative RBCs. Disclosures: No relevant conflicts of interest to declare.
