Abstract
Nosocomial infections are relatively common in the NICU. These infections increase morbidity and mortality, particularly in the smallest and most fragile infants. The impact of these infections on long-term outcomes and health-care costs is devastating. Worldwide efforts to decrease the incidence of nosocomial infections have focused on implementing specific prevention protocols such as handwashing, central line teams, care bundles, and antimicrobial stewardship. This review summarizes common nosocomial infections in patients in the NICU.

Abstract
Central line-associated bloodstream infections (CLABSIs) are common healthcare-associated infections in pediatrics. Children's hospital CLABSI standardized infection ratios decreased when comparing 2016-2019 (-26%, 95% CI [-31%, -20%]), and increased from 2019 to 2022 (18%, 95% CI [9%, 26%]). Resilient pediatric CLABSI prevention initiatives are needed.

Development and internal validation of a Neonatal Healthcare-associated infectiOn Prediction score (NeoHoP score) for very low birthweight infants in low-resource settings: a retrospective case-control study. BMJ Paediatr Open 2023; 7:e002056. [PMID: 37550083 PMCID: PMC10407408 DOI: 10.1136/bmjpo-2023-002056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 06/08/2023] [Indexed: 08/09/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Early diagnosis of neonatal infection is essential to prevent serious complications and to avoid unnecessary use of antibiotics. The prevalence of healthcare-associated infections (HAIs) among very low birthweight (VLBW; <1500 g) infants is 20%; and the mortality in low-resource settings can be as high as 70%. This study aimed to develop an Infection Prediction Score to diagnose bacterial HAIs. METHODS A retrospective cohort of VLBW infants investigated for HAI was randomised into two unmatched cohorts. The first cohort was used for development of the score, and the second cohort was used for the internal validation thereof. Potential predictors included risk factors, clinical features, interventions, and laboratory data. The model was developed based on logistic regression analysis. RESULTS The study population of 655 VLBW infants with 1116 episodes of clinically suspected HAIs was used to develop the model. The model had five significant variables: capillary refill time >3 s, lethargy, abdominal distention, presence of a central venous catheter in the previous 48 hours and a C reactive protein ≥10 mg/L. The area below the receiver operating characteristic curve was 0.868. A score of ≥2 had a sensitivity of 54.2% and a specificity of 96.4%. CONCLUSION A novel Infection Prediction Score for HAIs among VLBW infants may be an important tool for healthcare providers working in low-resource settings but external validation needs to be performed before widespread use can be recommended.

Early Diagnosis of Late-Onset Neonatal Sepsis Using a Sepsis Prediction Score. Microorganisms 2023; 11:microorganisms11020235. [PMID: 36838200 PMCID: PMC9964338 DOI: 10.3390/microorganisms11020235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 01/14/2023] [Accepted: 01/15/2023] [Indexed: 01/19/2023] Open
Abstract
Sepsis represents a common cause of morbidity in the Neonatal Intensive Care Unit (NICU). Our objective was to assess the value of clinical and laboratory parameters in predicting septicemia (positive blood culture) in NICU infants. In the first part of the present study (derivation cohort) we retrospectively reviewed the clinical files of 120 neonates with symptoms of suspected sepsis and identified clinical and laboratory parameters associated with proven sepsis on the day the blood culture was taken, as well as 24 h and 48 h earlier. These parameters were combined into a sepsis prediction score (SPS). Subsequently (validation study), we prospectively validated the performance of the SPS in a cohort of 145 neonates. The identified parameters were: temperature instability, platelet count < 150,000/mm3, feeding volume decrease > 20%, changes in blood glucose > 50%, CRP > 1 mg/dL, circulatory and respiratory deterioration. In the retrospective cohort, on the day the blood culture was obtained, a SPS ≥ 3 could predict sepsis with 82.54% sensitivity, 85.96% specificity, 5.88 PLR (Positive Likelihood Ratio), 0.20 NLR (Negative Likelihood Ratio), 86.67% PPV (Positive Predictive Value), 81.67% NPV (Negative Predictive Value) and 84.17% accuracy. In the prospective cohort, on the day the blood culture was obtained, a SPS ≥ 3 could predict sepsis with 76.60% sensitivity, 72.55% specificity, 2.79 PLR, 0.32 NLR, 83.72% PPV, 62.71% NPV and 75.17% accuracy. We concluded that this combination of clinical and laboratory parameters may assist in the prediction of septicemia in NICUs.

Abstract
Staphylococcus capitis, which causes bloodstream infections in neonatal intensive care units, is a common cause of healthcare-associated infections. Thus, a standardized high-resolution typing method to document the transmission and dissemination of multidrug-resistant S. capitis isolates is required. We aimed to establish a core genome multilocus sequence typing (cgMLST) scheme to surveil S. capitis. The cgMLST scheme was defined based on primary and validation genome sets and tested with outbreaks of linezolid-resistant isolates and a validation set. Phylogenetic analysis was performed to investigate the population structure and compare it with the result of cgMLST analysis. The S. capitis population consists of 1 dominant, NRCS-A, and 4 less common clones. In this work, a multidrug-resistant clone (L clone) with linezolid resistance is identified. With the features of type III SCCmec and multiple copies of mutations of G2576T and C2104T in the 23S rRNA, the L clone has been spreading silently across China. Staphylococcus capitis is a common causative agent of bloodstream infections in neonatal intensive care units, with multidrug resistant isolates complicating treatment. Authors aimed to establish a core genome multilocus sequence typing (cgMLST) scheme to document the transmission and dissemination of multidrug-resistant S. capitis isolates.

Abstract
BACKGROUND We aimed to develop and validate a diagnostic model for sepsis among neonates evaluated for suspected sepsis, by incorporating thromboelastometry parameters, maternal/neonatal risk factors, clinical signs/symptoms and laboratory results. METHODS This retrospective cohort study included 291 neonates with presumed sepsis, hospitalized in a NICU, from 07/2014 to 07/2021. Laboratory tests were obtained on disease onset and prior to initiating antibiotic therapy. Τhromboelastometry extrinsically activated (EXTEM) assay was performed simultaneously and Tοllner and nSOFA scores were calculated. Sepsis diagnosis was the outcome variable. A 10-fold cross-validation least absolute shrinkage and selection operator logit regression procedure was applied to derive the final multivariable score. Clinical utility was evaluated by decision curve analysis. RESULTS Gestational age, CRP, considerable skin discoloration, liver enlargement, neutrophil left shift, and EXTEM A10, were identified as the strongest predictors and included in the Neonatal Sepsis Diagnostic (NeoSeD) model. NeoSeD score demonstrated excellent discrimination capacity for sepsis and septic shock with an AUC: 0.918 (95% CI, 0.884-0.952) and 0.974 (95% CI, 0.958-0.989) respectively, which was significantly higher compared to Töllner and nSOFA scores. CONCLUSIONS The NeoSeD score is simple, accurate, practical, and may contribute to a timely diagnosis of sepsis in neonates with suspected sepsis. External validation in multinational cohorts is necessary before clinical application.

Abstract
Aim Nosocomial infections (NI) in neonates are associated with prolonged hospitalisation, adverse neurodevelopmental outcome and high mortality. Over the past decade, numerous prevention strategies have resulted in significant reductions in NI rates. In this review, we aim to provide an overview of current NI rates from large, geographically defined cohorts. Methods PubMed, Web of Science, EMBASE and Cochrane Library were searched for evidence regarding epidemiology and prevention of NI in neonates. Extracted studies were synthesised in a narrative form with experiential reflection. Results Despite the abundance of geographically defined incidence proportions, an epidemiological overview of NI is difficult to provide, given the lack of consensus definition for neonatal NI and different baseline populations being compared. Successful prevention efforts have focused on implementing evidence‐based practices while eliminating outdated strategies. The most promising model for reduction in infection rates is based on quality improvement (QI) collaboratives and benchmarking, involving identification and implementation of best practices, selection of measurable outcomes and fostering a sense of community and transparency. Conclusion The preventative rather than curative approach forms the new paradigm for reducing the burden of neonatal infections. Despite progress achieved, continued work towards improved prevention practices is required in the strive towards zero NIs.

Abstract
BACKGROUND Healthcare-acquired infections (HAIs) in the neonatal period cause substantial morbidity, mortality, and healthcare costs. Our purpose was to determine the prevalence of HAIs, antimicrobial susceptibility of causative agents, and the adaptivity of the Centres for Disease Control and Prevention (CDC) criteria in neonatal HAI diagnosis. METHODS A HAI point prevalence survey was conducted in the neonatal intensive care units (NICUs) of 31 hospitals from different geographic regions in Turkey. RESULTS The Point HAI prevalence was 7.6%. Ventilator-associated pneumonia (VAP) and central line-associated bloodstream infections (CLABSI) and late onset sepsis were predominant. The point prevalence of VAP was 2.1%, and the point prevalence of CLABSI was 1.2% in our study. The most common causative agents in HAIs were Gram-negative rods (43.0%), and the most common agent was Klebsiella spp (24.6%); 81.2% of these species were extended spectrum beta-lactamase (ESBL) (+). Blood culture positivity was seen in 33.3% of samples taken from the umbilical venous catheter, whereas 0.9% of samples of peripherally inserted central catheters (PICCs) were positive. In our study, 60% of patients who had culture positivity in endotracheal aspirate or who had purulent endotracheal secretions did not have any daily FiO2 change (p = 0.67) and also 80% did not have any increase in positive end-expiratory pressure (PEEP) (p = 0.7). On the other hand, 18.1% of patients who had clinical deterioration compatible with VAP did not have endotracheal culture positivity (p = 0.005). CONCLUSIONS Neonatal HAIs are frequent adverse events in district and regional hospitals. This at-risk population should be prioritized for HAI surveillance and prevention programs through improved infection prevention practices, and hand hygiene compliance should be conducted. CDC diagnostic criteria are not sufficient for NICUs. Future studies are warranted for the diagnosis of HAIs in NICUs.

Shifting focus toward healthcare-associated bloodstream infections: The need for neonatal intensive care unit-specific NHSN definitions. Infect Control Hosp Epidemiol 2021; 41:181-186.

Abstract
OBJECTIVE Healthcare-associated bloodstream infections (HABSIs) are a significant cause of mortality and morbidity in the neonatal intensive care unit (NICU) population. Our objectives were to review the epidemiology of HABSIs in our NICU and to examine the applicability of National Healthcare Safety Network (NHSN) definitions to the NICU population. METHODS We performed a retrospective review of all neonates admitted to the 54-bed, level IV NICU at Yale-New Haven Children's Hospital with a HABSI between January 1, 2013, and December 31, 2018. Clinical definitions per NICU team and NHSN site-specific definitions used for source identification were compared using the McNemar χ2 test. RESULTS We identified 86 HABSIs with an incidence rate of 0.80 per 1,000 patient days. Only 13% of these were CLABSIs. Both CLABSIs and non-catheter-related bloodstream infections occurred primarily in preterm neonates, but the latter were associated with a significantly higher incidence of comorbidities and the need for respiratory support. The NHSN definitions were less likely to identify a source compared to the clinical definitions agreed upon by our NICU treating team (P < .001). Furthermore, 50% of patients without an identified source of infection by NHSN definitions were bacteremic with a mucosal barrier injury organism, likely from gut translocation. CONCLUSIONS HABSIs occur primarily in premature infants with comorbidities, and CLABSIs account for a small proportion of these infections. With the increasing focus on HABSI prevention, there is a need for better NHSN site-specific definitions for the NICU population to prevent misclassification and direct prevention efforts.

The Effect of Single-Room Care Versus Open-Bay Care on the Incidence of Bacterial Nosocomial Infections in Pre-Term Neonates: A Retrospective Cohort Study. Infect Dis Ther 2020; 10:1-14. [PMID: 33362985 PMCID: PMC7756131 DOI: 10.1007/s40121-020-00380-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Accepted: 11/28/2020] [Indexed: 11/16/2022] Open
Abstract
INTRODUCTION Nosocomial infections (NIs) are a major source of iatrogenic harm in neonatal intensive care units (NICUs). The influence of the infrastructure of NICUs on NIs is not well documented. This study aims to examine the effect of single-room units (SRU) versus open-bay units (OBU) on the incidence of NIs, including central-line-associated bloodstream infections (CLABSI), in preterm neonates. METHODS All preterm neonates (< 32 weeks gestational age) admitted to our NICU were included. Two study periods were compared: one prior to (May 2015-May 2017) and one following (May 2017-May 2019) transition from OBU to SRU. Incidence density (number of infections per 1000 patient-days) and cumulative incidence (number of infections per 100 neonates) for NIs were calculated. CLABSIs were calculated per 1000 central-line days. U chart analysis was performed to determine special-cause variation in quarterly CLABSI and NI rates. Multivariate competing risk regression was performed to identify independent NI risk factors. RESULTS Of the 712 included infants, 164 (23%) infants acquired ≥ 1 NIs. No differences were found in incidence density (13.68 vs. 12.62, p = 0.62) or cumulative incidence of NI (23.97 vs. 22.02, p = 0.59) between OBU and SRU. CLABSIs showed a similar non-significant reduction after the move (14.00 vs. 10.59, p = 0.51). U chart analysis did not identify unit transition as a potential source of special-cause variation for CLABSI and NI. Competing risks regression analysis revealed longer duration of invasive mechanical ventilation as a significant risk factor for NI (subhazards ratio: 1.03 per day on ventilation, p = 0.01). CONCLUSION Single-rooms are not associated with a significant reduction in NIs in the NICU. This study therefore does not add evidence that could support the transition to SRUs if based only on a large multimodal infection control strategy. Recommendations to build SRUs would require a wider justification, also taking into account other SRU benefits.

Abstract
BACKGROUND Most studies regarding late-onset sepsis (LOS) address selected populations (i.e., neonates with low birth weight or extremely preterm neonates). Studying all age groups is more suitable to assess the burden of single pathogens and their clinical relevance. METHODS This is a retrospective regional study involving paediatric departments and NICUs in Emilia-Romagna (Italy). Regional laboratory databases were searched from 2009 to 2012. Records of infants (aged 4 to 90 days) with a positive blood or cerebrospinal fluid (CSF) culture were retrospectively reviewed and analysed according to acquisition mode (whether hospital- or community-acquired). RESULTS During the study period, there were 146,682 live births (LBs), with 296 patients experiencing 331 episodes of LOS (incidence rate: 2.3/1000 LBs). Brain lesions upon discharge from the hospital were found in 12.3% (40/296) of cases, with death occurring in 7.1% (23/296; 0.14/1000 LBs). With respect to full-term neonates, extremely preterm or extremely low birth weight neonates had very high risk of LOS and related mortality (> 100- and > 800-fold higher respectively). Hospital-acquired LOS (n = 209) was significantly associated with very low birth weight, extremely preterm birth, pneumonia, mechanical ventilation, and death (p< 0.01). At multivariate logistic regression analysis, catecholamine support (OR = 3.2), central venous line before LOS (OR = 14.9), and meningitis (OR = 44.7) were associated with brain lesions or death in hospital-acquired LOS (area under the ROC curve 0.81, H-L p = 0.41). Commonly identified pathogens included coagulase-negative staphylococci (CoNS n = 71, 21.4%), Escherichia coli (n = 50, 15.1%), Staphylococcus aureus (n = 41, 12.4%) and Enterobacteriaceae (n = 41, 12.4%). Group B streptococcus was the predominant cause of meningitis (16 of 38 cases, 42%). Most pathogens were sensitive to first line antibiotics. CONCLUSIONS This study provides the first Italian data regarding late-onset sepsis (LOS) in all gestational age groups. Compared to full-term neonates, very high rates of LOS and mortality occurred in neonates with a lower birth weight and gestational age. Group B streptococcus was the leading cause of meningitis. Excluding CoNS, the predominant pathogens were Escherichia coli and Staphylococcus aureus. Neonates with hospital-acquired LOS had a worse outcome. Antibiotic associations, recommended for empirical treatment of hospital- or community-acquired LOS, were adequate.

Abstract
Background To investigate the trends in the incidence and associated factors of late-onset sepsis (LOS) associated with improved survival in extremely preterm infants. Methods Medical records of 364 infants who were born at 23–26 weeks’ gestation from 2000 to 2005 (period I, n = 124) and from 2006 to 2011 (period II, n = 240) were retrospectively reviewed. The infants were stratified into subgroups of 23–24 and 25–26 weeks’ gestation within each period, and survival, LOS rate, and clinical characteristics were analyzed. Multivariate logistic regression analyses were completed to identify the clinical factors associated with LOS. Results The survival rate of 75.8% during period I significantly improved to 85.4% during period II, especially in infants at 23–24 weeks’ gestation (55.1% vs. 78.1%, respectively). The LOS rate of 33.1% during period I significantly reduced to 15.8% during period II, especially in infants at 25–26 weeks’ gestation (32.0% vs. 8.9%, respectively). The LOS rate per 1000 hospital days of 4.0 during period I significantly reduced to 1.8 during period II. Candida presence reduced from 21.3% during period I to 4.7% during period II. In multivariate analyses, during period I, prolonged intubation, especially in infants at 25–26 weeks’ gestation, and necrotizing enterocolitis, especially in infants at 23–24 weeks’ gestation, were significantly associated with LOS. Conclusions Improved survival of infants at 23–24 weeks’ gestation was associated with a simultaneous reduction of LOS incidence in infants at 25–26 weeks’ gestation. Less-invasive assisted ventilation may be one of the details of improved perinatal and neonatal care that has contributed to lowering risk of infection or death among periviable infants.

Abstract
Quality improvement in health care is an ongoing challenge. Consideration of the context of the health care system is of paramount importance. Staff resilience and teamwork climate are key aspects of context that drive quality. Teamwork climate is dynamic, with well-established tools available to improve teamwork for specific tasks or global applications. Similarly, burnout and resilience can be modified with interventions such as cultivating gratitude, positivity, and awe. A growing body of literature has shown that teamwork and burnout relate to quality of care, with improved teamwork and decreased burnout expected to produce improved patient quality and safety.

Abstract
OBJECTIVE Late-onset sepsis (LOS) in neonates contributes significantly to both morbidity and mortality. To determine the incidence of LOS, risk factors for disease and the impact on subsequent hospital course, we evaluated a cohort of 6340 neonates admitted to the neonatal intensive care unit and of neonates (3-28 days) admitted from the community between January 2005 and January 2016. METHODS This was a retrospective case review of all neonates admitted with suspected LOS who had positive blood culture and/or cerebrospinal fluid cultures, for an organism determined to be a pathogen. RESULTS Of 6340 neonates who survived beyond 3 days, 2271 (35.8%) had 1 or more blood cultures collected for suspected LOS. Of these, 146 (6.4%) positive blood cultures were thought to represent true bacteremia. The vast majority of infections (73%) were caused by Gram-positive organisms, with coagulase-negative staphylococci accounting for 39.8% of infections. Late-onset neonatal sepsis occurred predominantly in the 24-28-week age group (75.9%) and in neonates who weighed less than 1000 g (73.6%). The incubation time for positive blood cultures for Gram-negative sepsis was less (13 hours) when compared with Gram-positive sepsis (20 hours). Thrombocytopenia, elevated C-reactive protein and chorioamnionitis were consistently associated with late-onset Gram-negative sepsis (P < 0.05). Eight neonates (6%) died secondary to LOS. CONCLUSIONS LOS contributes significantly to mortality and morbidity in neonates and remains a challenge to clinicians. Necessary steps to reduce late-onset neonatal sepsis should be undertaken.

Abstract
Central line-associated bloodstream infections (CLABSI) are among the most common healthcare-acquired infections in the neonatal intensive care unit (NICU) population and are associated with an increased risk of morbidity and mortality, as well as increased healthcare costs, and duration of hospitalization. Over the past decade, numerous local, statewide, and national quality improvement initiatives have resulted in a significant reduction in CLABSI rates. The majority of successful initiatives have utilized similar strategies to implement and sustain their efforts, including education of NICU staff in the principles of quality improvement, creation and implementation of central line insertion and maintenance bundles and methods for assessing compliance, formation of dedicated central line insertion and maintenance teams, and utilization of reliable and effective methods for collecting, analyzing, and displaying data. Despite this progress, continued work toward discovery of better practices, such as the safest and most effective agent for cutaneous antisepsis or identification of optimal outcome and process measures, is required if further progress is to be made. Additionally, sustained progress in reducing the burden of neonatal infections may require a shift in focus away from CLABSI and toward the reporting, investigation, and prevention of all NICU-onset bacteremia.

Abstract
BACKGROUND Newborns are a population in which antibiotic consumption is extremely high. Targeted antibiotic therapy should help to reduce antibiotics consumption. The aim of this study was an assessment of antibiotic usage in bloodstream infections treatment in the Polish Neonatology Surveillance Network (PNSN) and determining the possibility of applying this kind of data in infection control, especially for the evaluation of standard methods of microbiological diagnostics. METHODS Data were collected between 01.01.2009 and 31.12.2013 in five teaching NICUs from the PNSN. The duration of treatment in days (DOT) and the defined daily doses (DDD) were used for the assessment of antibiotics consumption. RESULTS The median DOT for a single case of BSI amounted to 8.0 days; whereas the median consumption expressed in DDD was 0.130. In the case of laboratory confirmed BSI, median DOT was 8 days, and consumption-0.120 DDD. Median length of therapy was shorter for unconfirmed cases: 7 days, while the consumption of antibiotics was higher-0.140 DDD (p < 0.0001). High consumption of glycopeptides expressed in DOTs was observed in studied population, taking into account etiology of infection. CONCLUSIONS Even application of classical methods of microbiological diagnostics significantly reduces the consumption of antibiotics expressed by DDD. However, the high consumption of glycopeptides indicates the necessity of applying rapid diagnostic assays. Nevertheless, the assessment of antibiotic consumption in neonatal units represents a methodological challenge and requires the use of different measurement tools.

Abstract
INTRODUCTION This study aimed to determine whether patient loads, infant status on admission and treatment interventions were significantly associated with inter-institutional variations in sepsis rates in very-low-birth-weight (VLBW) infants in the Malaysian National Neonatal Registry (MNNR). METHODS This was a retrospective study of 3,880 VLBW (≤ 1,500 g) infants admitted to 34 neonatal intensive care units (NICUs) in the MNNR. Sepsis was diagnosed in symptomatic infants with positive blood culture. RESULTS Sepsis developed in 623 (16.1%) infants; 61 (9.8%) had early-onset sepsis (EOS) and 562 (90.2%) had late-onset sepsis (LOS). The median EOS rate of all NICUs was 1.0% (interquartile range [IQR] 0%, 2.0%). Compared with NICUs reporting no EOS (n = 14), NICUs reporting EOS (n = 20) had significantly higher patient loads (total live births, admissions, VLBW infants, outborns); more mothers with a history of abortions, and antenatal steroids and intrapartum antibiotic use; more infants requiring resuscitation procedures at birth; higher rates of surfactant therapy, pneumonia and insertion of central venous catheters. The median LOS rate of all NICUs was 14.5% (IQR 7.8%, 19.2%). Compared with NICUs with LOS rates below the first quartile (n = 8), those above the third quartile (n = 8) used less intrapartum antibiotics, and had significantly bigger and more mature infants, more outborns, as well as a higher number of sick infants requiring ventilator support and total parenteral nutrition. CONCLUSION Patient loads, resuscitation at birth, status of infants on admission and treatment interventions were significantly associated with inter-institutional variations in sepsis.

Abstract
CONTEXT NICUs in the province of Québec have seen an increase in hVICoNS, detected in the clinical laboratory. OBJECTIVE To investigate the clinical relevance of hVICoNS on the course of infection, and to determine the prevalence of hVICoNS sepsis in the NICU. METHODS We searched MEDLINE, EMBASE, and PubMed from 1 January 1980 to 1 July 2016. Both observational and interventional studies were considered eligible if they provided data on hVICoNS in the NICU population. Two investigators independently reviewed studies for data extraction. Data extracted included: number of CoNS cultures, prevalence of hVICoNS, and clonality of strains. RESULTS Of the 613 studies identified, 19 studies were reviewed, and 5 studies included in the final review. No studies addressed the clinical significance of hVICoNS in the NICU. The prevalence of hVICoNS in the NICU varied greatly, ranging from 2.3% to 100%. LIMITATIONS Publication bias could not be assessed, and risk of bias in some of the included studies due to small sample size and poor methods reporting. The quality of all included studies was low according to GRADE criteria, and the inclusion criteria restricted to either English or French studies. CONCLUSIONS Our review suggests that heteroresistance to vancomycin is much more common than previously believed. Our search however did not identify any studies that explicitly assessed any clinical implications of hVICoNS infections, thereby highlighting the need for research to assess the true impact of hVICoNS infection and to determine its significance on patient mortality and morbidity in the NICU.

Abstract
Coagulase-negative staphylococci (CoNS) have become the leading cause of bloodstream infections (BSIs) in intensive care units (ICUs), particularly in premature neonates. Vancomycin-intermediate heteroresistant CoNS (hVICoNS) have been identified as sources of BSIs worldwide, and their potential to emerge as significant pathogens in the neonatal ICU (NICU) remains uncertain. This study describes the molecular epidemiology of an outbreak of vancomycin-heteroresistant (hV) Staphylococcus epidermidis central-line-associated BSI (CLABSI) in a single tertiary care NICU and compares it to a second tertiary care NICU that had not been associated with an outbreak. Between November 2009 and April 2014, 119 S. epidermidis CLABSIs were identified in two tertiary care NICUs in Quebec, Canada. Decreased vancomycin susceptibility was identified in about 88% of all collected strains using Etest methods. However, discrepancies were found according to the Etest and population analysis profiling-area under the concentration-time curve (PAP-AUC) methods used. All strains were susceptible to linezolid, and a few isolates were nonsusceptible to daptomycin. Great genetic diversity was observed within the collection, with 31 pulsed-field gel electrophoresis (PFGE) patterns identified. The outbreak strains were all determined to be heteroresistant to vancomycin and were polyclonal. The study identified two major clones, PFGE patterns E and G, which were found in both NICUs across the 5-year study period. This suggests the persistence of highly successful clones that are well adapted to the hospital environment. hV S. epidermidis seems more common than currently realized in the NICU, and certain hV S. epidermidis clones can become endemic to the NICU. The reservoirs for these clones remain unknown at this time, and identification of the reservoirs is needed to better understand the impact of hV S. epidermidis in the NICU and to inform infection prevention strategies. In addition, there is a need to investigate and validate hV determination protocols for different species of CoNS.

Abstract
OBJECTIVE Central-line-associated bloodstream infections (CLABSI) are an important cause of morbidity and mortality in neonates. We aimed to determine whether intra-abdominal pathologies are an independent risk factor for CLABSI. METHODS We performed a retrospective matched case-control study of infants admitted to the neonatal intensive care units (NICUs) of the Montreal Children's Hospital (Montreal) and the Royal Alexandra Hospital, Edmonton, Canada. CLABSI cases that occurred between April 2009 and March 2014 were identified through local infection control databases. For each case, up to 3 controls were matched (National Healthcare Safety Network [NHSN] birth weight category, chronological age, and central venous catheter (CVC) dwell time at the time of CLABSI onset). Data were analyzed using conditional logistic regression. RESULTS We identified 120 cases and 293 controls. According to a matched univariate analysis, the following variables were significant risk factors for CLABSI: active intra-abdominal pathology (odds ratio [OR], 3.4; 95% confidence interval [CI], 1.8-6.4), abdominal surgery in the prior 7 days (OR, 3.5; 95% CI, 1.0-10.9); male sex (OR, 1.7; 95% CI, 1.1-2.6) and ≥3 heel punctures (OR, 4.0; 95% CI, 1.9-8.3). According to a multivariate matched analysis, intra-abdominal pathology (OR, 5.9; 95% CI, 2.5-14.1), and ≥3 heel punctures (OR, 5.4; 95% CI, 2.4-12.2) remained independent risk factors for CLABSI. CONCLUSION The presence of an active intra-abdominal pathology increased the risk of CLABSI by almost 6-fold. Similar to CLABSI in oncology patients, a subgroup of CLABSI with mucosal barrier injury should be considered for infants in the NICU with active intra-abdominal pathology.

Abstract
UNLABELLED Healthcare-associated sepsis (HAS) is a life-threatening complication in neonatal intensive care. Research into the impact of HAS on mortality adjusted for comorbidities is however limited. We conducted a historical cohort study to evaluate impact of HAS on mortality stratified by birth weight and risk factors for mortality in the HAS cohort. HAS was defined according to the National Institute of Child Health and Human Development criteria. Logistic regression was used to calculate adjusted odds of mortality. Of 5134 admissions, 342 infants developed HAS (6.7 %). Mortality in the total and HAS cohort was 5.6 and 10.5 %, respectively. The majority of HAS was caused by commensals (HAS-COM, 59.4 %) and 40.6 % by recognized pathogens (HAS-REC). Adjusted for comorbidities, "HAS-REC" is only a risk factor for mortality in newborns >1500 g (adjusted odds ratio [aOR] 2.3, confidence interval [CI] 1.1-4.9). Post-hoc analysis identified HAS-REC as an independent risk factor for mortality in infants with gastrointestinal disease (aOR 4.8, CI 2.1-10.8). "Renal insufficiency," "focal intestinal perforation," and "necrotizing enterocolitis" are independent risk factors for mortality in the HAS cohort (aOR 13.5, CI 4.9-36.6; aOR 7.7, CI 1.5-39.2; aOR 2.1, CI 1.0-4.7, respectively). CONCLUSION For very low birth weight infants (≤1500 g), several comorbidities overrule the impact of HAS on mortality. After adjustment for comorbidities, HAS-REC independently predicts in-hospital mortality in heavier infants and in those with gastrointestinal disease. WHAT IS KNOWN • The relationship between healthcare-associated sepsis and mortality is influenced by the causative pathogen and is confounded by comorbidities. • Research on impact of healthcare-associated sepsis on mortality adjusted for comorbidities is limited as well as research on independent risk factors for mortality in neonates with sepsis. What is New: • We included a large list of comorbidities and stratified risk by birth weight in order to assess the true effect of healthcare-associated sepsis on mortality. • Risk for mortality was calculated for commensal flora and for recognized pathogens as causative micro-organisms.

Early Hum Dev 2015; 91:677-81.

Abstract
AIMS The study investigated the association between clinical symptoms and late-onset sepsis (LOS) in preterm infants with the aim of identifying a non-invasive tool for the early detection of LOS. METHODS This was a prospective study of 83 episodes of suspected LOS in 67 preterm infants. At the time LOS was suspected, we recorded a standardized set of clinical symptoms. A diagnosis of "clinical LOS" (Clin-LOS), "culture-proven LOS" (Prov-LOS) or "LOS not present" (No-LOS) was made on the basis of C-reactive protein (CrP) and blood culture results where Clin-LOS was defined as CrP>10mg/l, Prov-LOS was defined as CrP>10mg/l AND positive blood cultures, or it was established that there was no sepsis present (No-LOS). We examined univariable associations between clinical signs and LOS using odds ratio (OR) analysis and then adjusted the odds ratio (adOR) through binary regression analysis. RESULTS Clin-LOS was diagnosed in 20/83 episodes, 19 cases were found to have Prov-LOS. Clinical signs which had a significant association with Clin-LOS were capillary refill time >2s (OR 2.9) and decreased responsiveness (OR 5.2), whereas there was a negative association between gastric residuals and LOS (OR 0.35). However, the most marked association was found for a greater central-peripheral temperature difference (cpTD) >2°C (OR 9). In Prov-LOS an increased heart rate (OR 3.1), prolonged capillary refill time (OR 3.3) and again an increased cpTD (OR 16) had a significant association with LOS, whereas gastric residuals were negatively associated (OR 0.29). Regression analysis showed that cpTD was the most striking clinical sign associated with both Clin- (adOR 6.3) and Prov-LOS (adOR 10.5). CONCLUSIONS Prolonged capillary refill time and - more impressive - elevated cpTD were the most useful clinical symptoms for detection of LOS in preterm infants. We especially suggest using cpTD as a predictor of LOS. It is a cheap, non-invasive and readily available tool for daily routines.

Abstract
BACKGROUND AND OBJECTIVE Central venous catheters in the NICU are associated with significant morbidity and mortality because of the risk of central line-associated bloodstream infections (CLABSIs). The purpose of this study was to determine the effect of catheter dwell time on risk of CLABSI. METHODS Retrospective cohort study of 13,327 infants with 15,567 catheters (93% peripherally inserted central catheters [PICCs], 7% tunneled catheters) and 256,088 catheter days cared for in 141 NICUs. CLABSI was defined using National Health Surveillance Network criteria. We defined dwell time as the number of days from line insertion until either line removal or day of CLABSI. We generated survival curves for each week of dwell time and estimated hazard ratios for CLABSI at each week by using a Cox proportional hazards frailty model. We controlled for postmenstrual age and year, included facility as a random effect, and generated separate models by line type. RESULTS Median postmenstrual age was 29 weeks (interquartile range 26-33). The overall incidence of CLABSI was 0.93 per 1000 catheter days. Increased dwell time was not associated with increased risk of CLABSI for PICCs. For tunneled catheters, infection incidence was significantly higher in weeks 7 and 9 compared with week 1. CONCLUSIONS Clinicians should not routinely replace uninfected PICCs for fear of infection but should consider removing tunneled catheters before week 7 if no longer needed. Additional studies are needed to determine what daily maintenance practices may be associated with decreased risk of infection, especially for tunneled catheters.

Abstract
BACKGROUND Health care-associated bloodstream infection (HABSI) is a frequent complication in neonatal intensive care. Research on risk factors stratified by birth weight and adjusted for severity of illness and comorbidities is limited. Our objective is to describe independent risk factors for HABSI in critically ill neonates with emphasis on risk variation between birth weight groups. METHODS We performed a single-center historical cohort study in a tertiary referral center. A neonatal intensive care-audit system was used to identify eligible neonates admitted for ≥72 hours (2002-2011). HABSI is defined according to National Institute of Child Health and Human Development criteria. Risk factors for HABSI were assessed by univariate and logistic regression analysis for the total cohort and for birth weight subgroups, that is, neonates ≤1500 g and >1500 g. RESULTS A total of 342 neonates developed HABSI in 5134 admissions of ≥72 hours (6.7%). Very low birth weight, total parenteral nutrition (TPN), mechanical ventilation, gastrointestinal disease, surgery (cardiac and other type), and renal insufficiency are independent risk factors for the total cohort. Gastrointestinal disease and cardiac surgery are independent risk factors in both birth weight groups; mechanical ventilation (odds ratio [OR]: 2.6; confidence interval [CI]: 1.6-4.0) and other type of surgery (OR: 4.3; CI: 2.1-8.8) are solely independent risk factors in the ≤1500-g cohort; TPN is exclusively an independent risk factor (OR: 7.9; CI: 3.9-16.2) in the >1500-g cohort. CONCLUSIONS In our neonatal intensive care unit, risk stratification by birth weight revealed some difference. Special attention concerning infection control practices is for neonates receiving TPN, mechanical ventilation, cardiac surgery, and with a gastrointestinal disease.

Abstract
BACKGROUND We investigated changes in the admission patterns of neonatal intensive care units and the epidemiology of neonatal sepsis following the rapid expansion and improvements in neonatal intensive care. METHODS Data on the admission of neonates with culture-proven sepsis between 1996 and 2013 (period I, 1996-2005; period II, 2006-2013) were collected retrospectively. RESULTS The admission of extremely low-birthweight (ELBW) infants increased between periods I and II (11.1 vs 28.7 infants per 1000 live births, P < 0.001). The survival rate of the ELBW infants improved (57.5 vs 80.1%, P < 0.001), and duration of hospital stay increased (median, 64 vs 80 days, P = 0.001). The incidence of sepsis among all infants and ELBW infants increased (all infants, 5.9 vs 12.7 cases per 1000 live births; ELBW infants, 189.5 vs 290.1 cases per 1000 live births). In ELBW infants, the incidence of sepsis caused by coagulase-negative Staphylococcus (CONS), significantly increased during period II (8.8 vs 25.4%, P = 0.039). On multivariate analysis, central vascular catheters and prolonged hospitalization were independently associated with increased sepsis rate, particularly CONS in ELBW infants. CONCLUSIONS The inborn admission rate for ELBW infants has increased significantly and is accompanied by improved survival and longer hospital stay. The incidence of neonatal sepsis, particularly in ELBW infants, has also increased, and CONS has emerged as a major pathogen. Central vascular catheters and prolonged hospitalization could be independent risk factors for the increased sepsis rate, particularly sepsis due to CONS.

Abstract
BACKGROUND To assess the ability of urinary neutrophil gelatinase-associated lipocalin (UNGAL) to discriminate between culture-positive vs. culture-negative late-onset sepsis evaluations. METHODS This is a prospective observational study of 136 neonates who underwent ≥1 sepsis evaluation at >72 h of age. Urine was obtained at the time of sepsis evaluation to measure UNGAL concentration. Using generalized estimating equations controlling for gender, gestational and postnatal age, acute kidney injury, and within-patient correlations, pair-wise contrasts between mean log UNGAL concentrations of infants with negative sepsis evaluations vs. culture-positive sepsis and presumed sepsis were assessed. Discrimination characteristics at several UNGAL cutoff concentrations were assessed using receiver-operating characteristic curves. RESULTS The predicted mean log UNGAL values of culture-positive sepsis and presumed sepsis vs. negative sepsis evaluations differed significantly (P < 0.001 and P = 0.02, respectively). At a cutoff ≥ 50 ng/ml, UNGAL discriminated between culture-positive sepsis and culture-negative sepsis evaluations with sensitivity = 86%, specificity = 56%, positive predictive value = 41%, negative predictive value = 92%, and number needed to treat = 3. CONCLUSION UNGAL is a noninvasive biomarker with high negative predictive value at the time of late-onset sepsis evaluation in neonates and could be a useful adjunct to traditional components of sepsis evaluations.

Abstract
BACKGROUND AND OBJECTIVES Blood culture is the gold standard to diagnose bloodstream infection but is usually time-consuming. Prediction models aim to facilitate early preliminary diagnosis and treatment. We systematically reviewed prediction models for health care-associated bloodstream infection (HABSI) in neonates, identified superior models, and pooled clinical predictors. DATA SOURCES LibHub, PubMed, and Web of Science. METHODS The studies included designed prediction models for laboratory-confirmed HABSI or sepsis. The target population was a consecutive series of neonates with suspicion of sepsis hospitalized for ≥ 48 hours. Clinical predictors had to be recorded at time of or before culturing. Methodologic quality of the studies was assessed. Data extracted included population characteristics, total suspected and laboratory-confirmed episodes and definition, clinical parameter definitions and odds ratios, and diagnostic accuracy parameters. RESULTS The systematic search revealed 9 articles with 12 prediction models representing 1295 suspected and 434 laboratory-confirmed sepsis episodes. Models exhibit moderate-good methodologic quality, large pretest probability range, and insufficient diagnostic accuracy. Random effects meta-analysis showed that lethargy, pallor/mottling, total parenteral nutrition, lipid infusion, and postnatal corticosteroids were predictive for HABSI. Post hoc analysis with low-gestational-age neonates demonstrated that apnea/bradycardia, lethargy, pallor/mottling, and poor peripheral perfusion were predictive for HABSI. Limitations include clinical and statistical heterogeneity. CONCLUSIONS Prediction models should be considered as guidance rather than an absolute indicator because they all have limited diagnostic accuracy. Lethargy and pallor and/or mottling for all neonates as well as apnea and/or bradycardia and poor peripheral perfusion for very low birth weight neonates are the most powerful clinical signs. However, the clinical context of the neonate should always be considered.

Abstract
OBJECTIVE The aim of this study is to determine the validity and reliability of neutrophil CD64 in identifying infected infants and to evaluate the impact of this marker on clinical care. STUDY DESIGN Neutrophil CD64 index was incorporated in 371 infection evaluations in 234 infants (ages 1-293 days) from 2005 to 2009 and the impact of this change on clinical care was evaluated. RESULTS The sensitivity of the neutrophil CD64 assay was 87% in identifying 31 episodes of culture positive sepsis and 83% in identifying 12 infants with ventilator-associated pneumonia. There was no difference in the mean number of antibiotic days in infants with a normal CD64 versus those with a normal complete blood count (CBC) (p = 0.89), but twofold more infants were identified as "not infected" by CD64 than by CBC. CONCLUSION CD64 had a high sensitivity for identifying infected infants while also decreasing the number of infants that were exposed to unnecessary antibiotic use.

Abstract
PURPOSE OF REVIEW Neonates in intensive care are more susceptible to sepsis. Infection is commonly acquired via the transcutaneous portal. It is necessary to identify the most effective yet safest topical antiseptics for use in neonates to reduce nosocomial sepsis. RECENT FINDINGS Recent national surveys indicate that a wide range of topical antiseptic preparations are used in the neonatal nursery. There are very few comparative studies in neonates and no robust evidence in favour of any particular antiseptic. There are significant safety and potential toxicity issues for neonates with all the commonly used antiseptics, particularly in very small immature babies. There are no convincing roles for routine application of emollient creams on the skin, topical antiseptics on the umbilical stump, or maternal vaginal washes with chlorhexidine for the prevention of neonatal infection. SUMMARY Large multicentre trials are needed to determine the optimal antiseptic to use for neonates undergoing intensive care, especially for extremely preterm infants.

Abstract
AbstractObjective:To determine the incidence, clinical characteristics, and risk factors associated with the first culture-proven episode of sepsis among neonates in a neonatal intensive care unit (NICU).Setting:Level-II NICU in the United Kingdom.Patients:Neonates with their first culture-proven sepsis between January 1, 1996, and December 31, 2000.Methods:Demographic data were obtained from the NICU database and chart review. Sepsis was considered early (EOS; < 72 hours old) or late (LOS; > 72 hours old). Data were also collected on potential risk factors.Results:Among 14,767 live births, 1,612 (11%) neonates were admitted to the NICU during the study period. Nine hundred eight were screened for sepsis. One hundred twenty-four had at least one positive culture (overall sepsis rate of 8.4 per 1,000 live births [1%] or 77 per 1,000 NICU admissions). Twenty-four neonates had EOS and 100 had LOS. Coagulase-negative staphylococci (CoNS) and group B Streptococcus were the most frequent organisms causing EOS, whereas CoNS and Escherichia coli most frequently caused LOS. Birth before 30 weeks' gestation and birth weight less than 1,500 g were risk factors for sepsis. Resuscitation at birth was the leading risk factor for EOS and respiratory support prior to sepsis, presence of a central or peripheral catheter, and total parenteral nutrition were leading risk factors for LOS.Conclusions:A strong inverse relationship existed between gestational age of 30 weeks or younger and birth weight of 1,500 g or less and LOS. Resuscitation and indwelling intravenous catheters were also risk factors.

Abstract
Objective.To describe the relationship between the use of central and peripheral venous catheters and the risk of nosocomial, primary, laboratory-confirmed bloodstream infection (BSI) for neonates with a birth weight less than 1,500 g (very-low-birth-weight [VLBW] infants).Methods.Cox proportional hazard regression analysis with time-dependent variable was used to determine the risk factors for the occurrence of BSI in a cohort of VLBW infants. We analyzed previously collected surveillance data from the German national nosocomial surveillance system for VLBW infants. All VLBW infants in 22 participating neonatal departments who had a complete daily record of patient information were included.Results.Of 2,126 VLBW infants, 261 (12.3%) developed a BSI. The incidence density for BSI was 3.3 per 1,000 patient-days. The multivariate analysis identified the following significant independent risk factors for BSI: lower birth weight (hazard ratio [HR], 1.1–2.2), vaginal delivery (HR, 1.5), central venous catheter use (HR, 6.2) or peripheral venous catheter use (HR, 6.0) within 2 days before developing BSI, and the individual departments (HR, 0.0–4.6).Conclusions.After adjusting for other risk factors, use of peripheral venous catheter and use of central venous catheter were significantly related to occurrence of BSI in VLBW infants.

Abstract
Introduction. Blood stream infection (BSI) is a common problem of newborn in neonatal intensive care units (NICUs). Monitoring neonatal infections is increasingly regarded as an important contributor to safe and high-quality healthcare. It results in high mortality rate and serious complications. So, our aim was to determine the incidence and the pattern of BSIs in the NICU of Suez Canal University Hospital, Egypt, and to determine its impact on hospitalization, mortality, and morbidity. Methods. This study was a prospective one in which all neonates admitted to the NICUs in Suez Canal University hospital between January, 2013 and June 2013 were enrolled. Blood stream infections were monitored prospectively. The health care associated infection rate, mortality rate, causative organism, and risk factors were studied. Results. A total of 317 neonates were admitted to the NICU with a mortality rate of 36.0%. During this study period, 115/317 (36.3%) developed clinical signs of sepsis and were confirmed as BSIs by blood culture in only 90 neonates with 97 isolates. The total mean length of stay was significantly longer among infected than noninfected neonates (34.5 ± 18.3 and 10.8 ± 9.9 days, resp., P value < 0.001). The overall mortality rates among infected and noninfected neonates were 38.9% and 34.8%, respectively, with a significant difference. Klebsiella spp. were the most common pathogen (27.8%) followed by Pseudomonas (21.6%) and Staphylococcus aureus (15.4%). Conclusion. The rate of BSIs in NICU at Suez Canal University Hospital was relatively high with high mortality rate (36.0%).

Abstract
Background Late-Onset Bloodstream Infections (LO-BSI) continue to be one of the most important complications associated with hospitalization of infants born with very low birth weight (VLBW). The aims of this study were to assess the epidemiology of LO-BSI together with the risk factors and the distribution of causative pathogens at six Polish neonatal intensive care units that participated in the Polish Neonatology Surveillance Network from January 1, 2009 to December 31, 2011. Methods The surveillance covered 1,695 infants whose birth weights were <1501 grams (VLBW) in whom LO-BSI was diagnosed >72 hours after delivery. Case LO-BSI patients were defined according to NeoKISS. Results Four hundred twenty seven episodes of LO-BSI were diagnosed with a frequency of 25.3% and an incidence density of 6.7/1000 patient-days (pds). Results of our multivariate analysis demonstrated that surgical procedures and lower gestational age were significantly associated with the risk of LO-BSI. Intravascular catheters were used in infants with LO-BSI significantly more frequently and/or for longer duration: Central venous cathters (CVC) (OR 1.29) and Peripheral venous catheters (PVC) (OR 2.8), as well as, the total duration of total parenteral nutrition (13 vs. 29 days; OR 1.81). Occurrence of LO-BSI was significantly associated with increased the length of mechanical ventilation (MV) (OR 2.65) or the continuous positive airway pressure (CPAP) (OR 2.51), as well as, the duration of antibiotic use (OR 2.98). The occurrence of more than one infection was observed frequently (OR 9.2) with VLBW with LO-BSI. Microorganisms isolated in infants with LO-BSI were dominated by Gram-positive cocci, and predominantly by coagulase-negative staphylococci (62.5%). Conclusions Independent risk factor for LO-BSI in VLBV infants are: low gestational age and requirement for surgery. The incidence rates of LO-BSI especially CVC-BSI were higher in the Polish NICUs surveillance than those of other national networks, similar to the central- and peripheral utilization ratio.

Abstract
OBJECTIVE To analyze trends in the incidence and pathogen distribution of healthcare-associated bloodstream infections (HABSIs) over a 20-year period (1992-2011). DESIGN Historical cohort study. SETTING Thirty-two-bed neonatal intensive care unit (NICU) in a tertiary referral hospital. PATIENTS Neonates with HABSIs defined according to the criteria of the National Institute of Child Health and Development (NICHD). METHODS A hospital-based ongoing surveillance program was used to identify HABSI cases in neonates. A distinction between definite or possible HABSI was made according to the NICHD criteria. Incidence, incidence densities (HABSIs per 1,000 hospital-days and HABSIs per 1,000 total parenteral nutrition-days), and case fatality rate were calculated. Logistic regression analysis was used to find time trends. Four periods of 5 years were considered when executing variance analysis. RESULTS In total, 682 episodes of HABSIs occurred on 9,934 admissions (6.9%). The median total incidence density rate was 3.1 (interquartile range, 2.2-3.9). A significant increasing time trend in incidence density was observed for the period 1995-2011 (P < .003). A significant decrease in the case fatality rate was found in the last 5-year period (P < .001). No neonate died following possible HABSIs, whereas the case fatality rate among neonates with definite HABSIs was 9.7%. Most HABSIs were caused by coagulase-negative staphylococci (n = 414 [60.7%]). A significant increase in Staphylococcus aureus HABSI was observed in the last 10-year period (P < .001). CONCLUSIONS An increase in incidence density rate occurred, while the case fatality rate dropped. Better perinatal care could be responsible for the latter. A decrease in days before infection and a high incidence of coagulase-negative Staphylococcus HABSIs indicate the need for vigorous application of evidence-based prevention initiatives, in particular for catheter care.

Abstract
OBJECTIVE This study investigated the intestinal colonization with staphylococci in very low birth weight infants in relation to the type of enteral feeding and evaluated the intestine as potential source for staphylococcal bacteremia. PATIENTS AND METHODS Infants born in the Level III neonatal intensive care unit of a university hospital with a gestational age below 32 weeks and/or birth weight below 1,500 g were included in a prospective, observational study. The infants received either preterm formula or mother's own milk, with random allocation to raw or pasteurized milk. Precise viable staphylococcal counts of serial fecal specimens were examined in the first 8 weeks of life. In the case of bloodstream infection, fecal and blood isolates of staphylococci were compared by antibiotypes or pulsed-field gel electrophoresis. RESULTS One hundred fifty neonates, with a mean of 29 weeks of gestation and 1,260 g at birth, had 1,045 fecal samples analyzed and were found to be heavy carriers of staphylococci in the intestine with 10(6)-10(7) colony-forming units/g of feces from the first week of life. Colonization rate and patterns were not different in relation to the type of enteral feeding. In nearly 80% of 42 patients exhibiting a staphylococcal bloodstream infection, intestinal colonization retrieved a predominant strain that was different from the one recovered from the blood. CONCLUSIONS In very low birth weight infants, predominance of staphylococci in the gut is not related to the type of enteral feeding. An endogenous origin of staphylococcal bloodstream infection seems to play a minor role.

Abstract
BACKGROUND We aimed to characterize the clinical manifestations and outcomes of patients with Acinetobacter baumannii bacteremia in the neonatal intensive care unit (NICU). METHODS All patients with A baumannii bacteremia in our NICU from 2004 to 2010 were reviewed. A matched case-control study was performed by comparing each case of A baumannii to 2 uninfected controls and all cases of Escherichia coli and Klebsiella bacteremia, respectively. RESULTS Thirty-seven cases with A baumannii bacteremia were identified. Multidrug-resistant isolate was noted in only 2 cases (5.4%), and the overall mortality rate was 8.1%. Compared with matched, uninfected controls, infants with A baumannii were more likely to have had a central vascular catheter (CVC) (P = .009), use of total parenteral nutrition (TPN) (P = .021), longer duration of ventilator use (P = .002), and hospitalization (P = .010). Compared with E coli or Klebsiella bacteremia, infants with A baumannii bacteremia had lower birth weight (median of 1,090 g vs 1,300 g, P = .044) and a higher rate of CVC and TPN use (both P < .001) at the time of infection. CONCLUSION A baumannii bacteremia occurs endemically or sporadically in the NICU, primarily in low-birth-weight infants on TPN use and with CVC in situ. Although A baumannii does not often cause mortality, and multidrug-resistant A baumannii is uncommon, it contributes significantly to longer hospitalization.

Abstract
BACKGROUND Despite implementation of recommended best practices, our central line-associated bloodstream infection (CLABSI) rates remained high. Our objective was to describe the impact of chlorhexidine gluconate (CHG) bathing on CLABSI rates in neonates. METHODS Infants with a central venous catheter (CVC) admitted to the neonatal intensive care unit from April 2009 to March 2013 were included. Neonates with a birth weight of 1,000 g or less, aged less than 28 days, and those with a birth weight greater than 1,000 g were bathed with mild soap until March 31, 2012 (baseline), and with a 2% CHG-impregnated cloth starting on April 1, 2012 (intervention). Infants with a birth weight of 1,000 g or less, aged 28 days or more, were bathed with mild soap during the entire period. Neonatal intensive care unit nurses reported adverse events. Adjusted incidence rate ratios (aIRRs), using Poisson regression, were calculated to compare CLABSIs/1,000 CVC-days during the baseline and intervention periods. RESULTS Overall, 790 neonates with CVCs were included in the study. CLABSI rates decreased during the intervention period for CHG-bathed neonates (6.00 vs 1.92/1,000 CVC-days; aIRR, 0.33 [95% confidence interval (CI), 0.15-0.73]) but remained unchanged for neonates with a birth rate of 1,000 g or less and aged less than 28 days who were not eligible for CHG bathing (8.57 vs 8.62/1,000 CVC-days; aIRR, 0.86 [95% CI, 0.17-4.44]). Overall, 195 infants with a birth weight greater than 1,000 g and 24 infants with a birth weight of 1,000 g or less, aged 28 days or more, were bathed with CHG. There was no reported adverse event. CONCLUSIONS We observed a decrease in CLABSI rates in CHG-bathed neonates in the absence of observed adverse events. CHG bathing should be considered if CLABSI rates remain high, despite the implementation of other recommended measures.

Abstract
OBJECTIVE To examine the reporting of hospital-acquired bloodstream infection (HABSI) and central line-associated BSI (CLABSI) rates in neonatal intensive care units (NICUs). DESIGN Systematic review of evidence published after 2000 reporting HABSI cumulative incidence, crude HABSI and/or CLABSI rate and total patient-days and/or central line-days for single NICU. SETTING Inpatient. PATIENTS Neonates admitted to NICU. MAIN OUTCOME MEASURES To consider the reporting of and relationship between cumulative incidence of BSI and HABSI and/or CLABSI rates. RESULTS 18 studies fulfilled inclusion criteria. There was a wide variability in reporting of HABSI indicators and risk-adjustment strategies with reported crude HABSI and/or CLABSI rates showing an approximately sevenfold variation between centres. Information about NICU size and level of care was not always available. Many studies provided insufficient information about case mix, such as surgical care provision and prematurity. The proportion of total patient-days that were central venous catheters (CVC)-days ranged from 11.7% to 85.4%. Only six studies reported HABSI and CLABSI incidence. Comparing HABSI and CLABSI ranking, we found a relationship between rates. CONCLUSIONS We found significant variability in HABSI rate reporting. Although there appears to be an association between CLABSI and HABSI rates, non-CVC-related BSIs are likely to be highly relevant in some NICUs. If confirmed, and given CLABSI rates are more challenging to collect, it may be more appropriate to use HABSI rates for monitoring NICU healthcare-associated infection (HAI) in some settings. A European network of NICUs using a standardised methodology is required to determine the feasibility and reliability of different risk-adjusted measured of HAI rates.

Abstract
OBJECTIVE Describe the epidemiology of central line-associated bloodstream infections (CLABSIs) in neonatal intensive care units (NICUs) participating in a standardized and mandatory CLABSI surveillance program. DESIGN Retrospective cohort. Setting. We included patients admitted (April 2007-March 2011) to 7 level II/III NICUs who developed a CLABSI (as defined by the National Healthcare Safety Network). METHODS CLABSIs/1,000 central line-days and device utilization ratio were calculated; χ(2) test, Student t test, Kruskal-Wallis, and Poisson regression were used. RESULTS Overall, 191 patients had 202 CLABSI episodes for a pooled mean rate of 4.0 CLABSIs/1,000 central line-days and a device utilization ratio of 0.20. Annual pooled mean CLABSI rates increased from 3.6 in 2007-2008 to 5.1 CLABSIs/1,000 central line-days in 2010-2011 (P - .01). The all-cause 30-day case fatality proportion was 8.9% (n = 17) and occurred a median of 8 days after CLABSI. Coagulase-negative Staphylococcus was identified in 112 (50.5%) cases. Staphylococcus aureus was identified in 22 cases, and 3 (13.6%) were resistant to methicillin. An underlying intra-abdominal pathology was found in 20% (40/202) of CLABSI cases, 50% of which were reported in the last year of study. When adjusted for mean birth weight, annual CLABSI incidence rates were independently associated with the proportion of intra-abdominal pathology (P = .007) and the proportion of pulmonary pathology (P = .016) reported. CONCLUSION The increase in CLABSI rates in Quebec NICUs seems to be associated with an increased proportion of cases with underlying intra-abdominal and pulmonary pathologies, which needs further investigation.

Clinical signs to identify late-onset sepsis in preterm infants. Eur J Pediatr 2013; 172:501-8.

Abstract
UNLABELLED Late-onset neonatal sepsis (LOS) in preterm infants is an important cause of morbidity and mortality in preterm infants. Since presenting symptoms may be non-specific and subtle, early and correct diagnosis is challenging. We aimed to develop a nomogram based on clinical signs, to assess the likelihood of LOS in preterms with suspected infection without the use of laboratory investigations. We performed a prospective cohort study in 142 preterm infants <34 weeks admitted to the neonatal intensive care unit with suspected infection. During 187 episodes, 21 clinical signs were assessed. LOS was defined as blood culture-proven and/or clinical sepsis, occurring after 3 days of age. Logistic regression was used to develop a nomogram to estimate the probability of LOS being present in individual patients. LOS was found in 48 % of 187 suspected episodes. Clinical signs associated with LOS were: increased respiratory support (odds ratio (OR) 3.6; 95 % confidence interval (CI) 1.9-7.1), capillary refill (OR 2.2; 95 %CI 1.1-4.5), grey skin (OR 2.7; 95 %CI 1.4-5.5) and central venous catheter (OR 4.6; 95 %CI 2.2-10.0) (area under the curve of the receiver operating characteristic curve 0.828; 95 %CI 0.764-0.892). CONCLUSION Increased respiratory support, capillary refill, grey skin and central venous catheter are the most important clinical signs suggestive of LOS in preterms. Clinical signs that are too non-specific to be useful in excluding or diagnosing LOS were temperature instability, apnoea, tachycardia, dyspnoea, hyper- and hypothermia, feeding difficulties and irritability.

Abstract
BACKGROUND We determined the prevalence and risk factors for late-onset bloodstream infections (LO-BSI), the distribution of pathogens and the outcomes of affected preterm infants. METHODS The records of all preterm infants (<37 weeks gestation) born between 2004 and 2005 and hospitalized in the neonatal intensive care unit for >3 days were retrieved for this retrospective matched case-control study. RESULTS A total of 108 out of 1459 preterm infants (7.4%) had 142 episodes of LO-BSI. The highest LO-BSI rate (44%) was among 198 very-low-birthweight infants (<1500 g). The most common causative organisms were Coagulase-negative staphylococci and Klebsiella (60% and 13%, respectively). The mean hospital stay was 64 days for LO-BSI preterm infants versus 48 days for non-LO-BSI preterm infants. Congenital malformations and peripheral catheters were independent risk factors for LO-BSI. Crude mortality rates were 6.9% (LO-BSI) and 3.0% (non-LO-BSI), with an LO-BSI-attributable mortality of 3.9%. CONCLUSION LO-BSI frequently affect very-low-birthweight infants. Strategies to prevent LO-BSI should target peripheral catheters.

Abstract
INTRODUCTION Healthcare-associated infection is a common problem in patients from neonatal intensive care units and it is one of the leading causes of death in this group of patients. Healthcare-associated infections are associated with increases in mortality, morbidity, and prolonged length of hospital stay. The aim of the study was to assess the incidence, clinical presentation, mortality and aetiology of healthcare-associated infections in newborns in a neonatal intensive care unit between 2005 and 2010. MATERIAL AND METHODS The research involved documentation of 2610 neonates hospitalized in this period in the Neonatal Intensive Care Unit, Dr Jan Biziel University Hospital No. 2 in Bydgoszcz. The incidence, clinical presentation, mortality and causative factors of healthcare-associated infections were assessed. RESULTS The prevalence of healthcare-associated infections was 7.32%. The most frequent healthcare-associated infections were bloodstream infection (65.4%) and urinary tract infection (22.5%). The mortality rate was 2.1%. The most frequent pathogens were coagulase-negative staphylococci (36.1%) and Klebsiella pneumoniae (29.3%). CONCLUSIONS The rate of healthcare-associated bloodstream infections in the analysed department is low, taking into consideration the specificity of the department. There is a necessity to establish convenient definitions of various kinds of healthcare-associated infecions in neonates, especially those born preterm.

Pattern of bacterial colonization in a new neonatal intensive care unit and its association with infections in infants. Am J Infect Control 2012; 40:512-5. [PMID: 22854377 DOI: 10.1016/j.ajic.2012.02.016] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2011] [Revised: 02/03/2012] [Accepted: 02/03/2012] [Indexed: 11/22/2022]
Abstract
BACKGROUND There is paucity of information on the pattern of bacterial colonization of a new neonatal intensive care unit. OBJECTIVE To study the pattern of bacterial colonization on the environmental surfaces in a new neonatal intensive care unit (NICU) and correlate it with infections in the infants. METHODS Environmental cultures from the faucets and computer keyboards in the NICU were obtained prospectively every 2 weeks for 1 year. Positive blood, cerebrospinal fluid, and respiratory cultures from the infants in the NICU were also obtained. RESULTS A total of 175 swab cultures was collected, which were sterile for initial 6-week period. Subsequently, 31 cultures grew microbes: 26 (83.8%) from the faucets and 5 (16.2%) from the computers keyboard (P < .001). Of the 48 positive blood cultures in NICU patients, 6 (12.5%) matched the organism growing from the surveillance sites, but the correlation was not significant (P = .076). None of the 31 positive respiratory cultures and 1 positive cerebrospinal fluid culture correlated to the organisms grown from the NICU environment. CONCLUSION The environment was colonized after an initial period of sterile cultures in a new NICU. Once colonized, they can persist, increasing the risk of developing resistance to antibiotics. They did not correlate with the positive cultures from the infants admitted to the NICU during the study period.

Abstract
BACKGROUND Early-onset sepsis (EOS) is an important cause of morbidity and mortality in neonates, and its diagnosis remains challenging. The complete blood cell count and differential have been previously evaluated as diagnostic tools for EOS in small, single-center reports. We evaluated the diagnostic accuracy of the complete blood cell count and differential in EOS in a large, multicenter population of neonates admitted to the neonatal intensive care unit. METHODS Using a cohort of 166,092 neonates with suspected EOS with cultures admitted to 293 neonatal intensive care units, we calculated odds ratios and receiver operating characteristic curves for complete blood cell count indices and prediction of a positive culture. We determined sensitivity, specificity and likelihood ratios for various commonly used cutoff values from the complete blood cell count. RESULTS Low white blood cell counts, low absolute neutrophil counts and high immature-to-total neutrophil ratios were associated with increasing odds of infection (highest odds ratios: 5.38, 6.84 and 7.97, respectively). Specificity and negative predictive values were high (73.7%-99.9% and >99.8%). However, sensitivities were low (0.3%-54.5%) for all complete blood cell count indices analyzed. CONCLUSION Low white blood cell count, absolute neutrophil count and high immature-to-total neutrophil ratio were associated with increasing odds of infection, but no complete blood cell count-derived index possesses the sensitivity to rule out reliably EOS in neonates.
