Evaluating application of the National Healthcare Safety Network central line-associated bloodstream infection surveillance definition: a survey of pediatric intensive care and hematology/oncology units
Gaur AH , Miller MR , Gao C , Rosenberg C , Morrell GC , Coffin SE , Huskins WC . Infect Control Hosp Epidemiol 2013 34 (7) 663-70 OBJECTIVE: To evaluate the application of the National Healthcare Safety Network (NHSN) central line-associated bloodstream infection (CLABSI) definition in pediatric intensive care units (PICUs) and pediatric hematology/oncology units (PHOUs) participating in a multicenter quality improvement collaborative to reduce CLABSIs; to identify sources of variability in the application of the definition. DESIGN: Online survey using 18 standardized case scenarios. Each described a positive blood culture in a patient and required a yes- or-no answer to the question "Is this a CLABSI?" NHSN staff responses were the reference standard. SETTING: Sixty-five US PICUs and PHOUs. PARTICIPANTS: Staff who routinely adjudicate CLABSIs using NHSN definitions. RESULTS: Sixty responses were received from 58 (89%) of 65 institutions; 78% of respondents were infection preventionists, infection control officers, or infectious disease physicians. Responses matched those of NHSN staff for 78% of questions. The mean (SE) percentage of concurring answers did not differ for scenarios evaluating application of 1 of the 3 criteria ("known pathogen," 78% [1.7%]; "skin contaminant, >1 year of age," 76% [SE, 2.5%]; "skin contaminant, ≤1 year of age," 81% [3.8%]. The mean percentage of concurring answers was lower for scenarios requiring respondents to determine whether a CLABSI was present or incubating on admission (64% [4.6%]; or to distinguish between primary and secondary bacteremia (65% [2.5%]. CONCLUSIONS: The accuracy of application of the CLABSI definition was suboptimal. Efforts to reduce variability in identifying CLABSIs that are present or incubating on admission and in distinguishing primary from secondary bloodstream infection are needed. |
Device-associated infections among neonatal intensive care unit patients: incidence and associated pathogens reported to the National Healthcare Safety Network, 2006-2008
Hocevar SN , Edwards JR , Horan TC , Morrell GC , Iwamoto M , Lessa FC . Infect Control Hosp Epidemiol 2012 33 (12) 1200-6 OBJECTIVE: To describe rates and pathogen distribution of device-associated infections (DAIs) in neonatal intensive care unit (NICU) patients and compare differences in infection rates by hospital type (children's vs general hospitals). PATIENTS AND SETTING: Neonates in NICUs participating in the National Healthcare Safety Network from 2006 through 2008. METHODS: We analyzed central line-associated bloodstream infections (CLABSIs), umbilical catheter-associated bloodstream infections (UCABs), and ventilator-associated pneumonia (VAP) among 304 NICUs. Differences in pooled mean incidence rates were examined using Poisson regression; nonparametric tests for comparing medians and rate distributions were used. RESULTS: Pooled mean incidence rates by birth weight category (750 g or less, 751-1,000 g, 1,001-1,500 g, 1,501-2,500 g, and more than 2,500 g, respectively) were 3.94, 3.09, 2.25, 1.90, and 1.60 for CLABSI; 4.52, 2.77, 1.70, 0.91, and 0.92 for UCAB; and 2.36, 2.08, 1.28, 0.86, and 0.72 for VAP. When rates of infection between hospital types were compared, only pooled mean VAP rates were significantly lower in children's hospitals than in general hospitals among neonates weighing 1,000 g or less; no significant differences in medians or rate distributions were noted. Pathogen frequencies were coagulase-negative staphylococci (28%), Staphylococcus aureus (19%), and Candida species (13%) for bloodstream infections and Pseudomonas species (16%), S. aureus (15%), and Klebsiella species (14%) for VAP. Of 673 S. aureus isolates with susceptibility results, 33% were methicillin resistant. CONCLUSIONS: Neonates weighing 750 g or less had the highest DAI incidence. With the exception of VAP, pooled mean NICU incidence rates did not differ between children's and general hospitals. Pathogens associated with these infections can pose treatment challenges; continued efforts at prevention need to be applied to all NICU settings. |

National Healthcare Safety Network (NHSN) report, data summary for 2009, device-associated module
Dudeck MA , Horan TC , Peterson KD , Allen-Bridson K , Morrell GC , Pollock DA , Edwards JR . Am J Infect Control 2011 39 (5) 349-367 This report is a summary of Device-Associated (DA) module data collected by hospitals participating in the National Healthcare Safety Network (NHSN) for events occurring between January and December 2009 and reported to the Centers for Disease Control and Prevention (CDC) by October 18, 2010. This report updates previously published DA module data from the NHSN and provides contemporary comparative rates.1 Procedure-Associated module data will be reported separately. Surgical site infection data will be reported as standardized infection ratios using new logistic regression models, and postprocedure pneumonia rates for 2009 are available on the NHSN's public Web site. This report complements other NHSN reports, including national and state-specific standardized infection ratios for selected health care–associated infections (HAIs).2, 3, 4 | The NHSN was established in 2005 to integrate and supersede 3 legacy surveillance systems at the CDC: the National Nosocomial Infections Surveillance system, the Dialysis Surveillance Network, and the National Surveillance System for Healthcare Workers. NHSN data collection, reporting, and analysis are organized into 3 components—Patient Safety, Healthcare Personnel Safety, and Biovigilance—and use standardized methods and definitions in accordance with specific module protocols.5, 6, 7 The modules may be used singly or simultaneously, but once selected, they must be used for a minimum of 1 calendar month. All infections are categorized using standard CDC definitions that include laboratory and clinical criteria.7 The DA module may be used by facilities other than hospitals, including long-term care facilities and outpatient dialysis centers. A report of data from this module for outpatient dialysis centers has been published separately.8 For this report, only data from the Patient Safety component are presented. NHSN facilities report their HAI surveillance data voluntarily or in response to state mandatory reporting requirements. The CDC aggregates these data into a single national database for the stated purposes in place in 2009, as follows: | • | Collect data from a sample of US health care facilities to permit valid estimation of the magnitude of adverse events among patients and health care personnel. | • | Collect data from a sample of US health care facilities to permit valid estimation of the adherence to practices known to be associated with prevention of these adverse events. | • | Analyze and report collected data to permit recognition of trends. | • | Provide facilities with risk-adjusted metrics that can be used for interfacility comparisons and local quality improvement activities. | • | Assist facilities in developing surveillance and analysis methods that permit timely recognition of patient and health care worker safety problems and prompt intervention with appropriate measures. | • | Conduct collaborative research studies with NHSN member facilities (eg, describe the epidemiology of emerging HAIs and pathogens, assess the importance of potential risk factors, further characterize HAI pathogens and their mechanisms of resistance, and evaluate alternative surveillance and prevention strategies). | | The identity of each NHSN facility is kept confidential by the CDC in accordance with Sections 304, 306, and 308(d) of the Public Health Service Act [42 USC 242b, 242K, and 242m(d)]. |
