RESUMEN
We report 2 infants hospitalized with Cronobacter sakazakii meningitis. Each infant had exposure to powdered infant formula at home. Both infants survived, but 1 infant had a subdural empyema drained and developed left sensorineural hearing loss. Early advanced brain imaging is recommended in infants with C. sakazakii meningitis. Reporting to state and federal public health officials may help identify outbreaks.

BACKGROUND: The role of home antibiotics (HA) at discharge in children after perforated appendicitis is unclear. This study evaluates the outcomes of complicated appendicitis in patients being discharged with or without HA after initial operation and inpatient treatment. STUDY DESIGN: The 2015 and 2016 NSQIP-Pediatric database was queried for patients younger than 18 years of age with complicated appendicitis. Home antibiotics were prescribed or not (no home antibiotics [NHA]). Patients were stratified based on presence or absence of predischarge surgical site infection (SSI) and postoperative day of discharge (≤5 days or >5 days). The primary end point was 30-day postdischarge composite morbidity, including emergency department visit, readmission, postdischarge reoperation, and SSI. Multivariable logistic regression was used to adjust for baseline covariables. RESULTS: Of 6,412 patients with complicated appendicitis, the majority were discharged with HA (HA 56.4%; NHA 43.6%). Patients receiving HA had higher preoperative leukocytosis, longer procedures, higher incidence of sepsis, more predischarge SSIs, and longer length of stay than the NHA cohort (all p < 0.01), suggesting greater severity of illness. In adjusted multivariable models, HA patients without a predischarge SSI had higher postdischarge morbidity (adjusted odds ratio [aOR] 1.22; 95% CI 1.04 to 1.44), as did HA patients discharged ≤5 days post operation (aOR 1.28; 95% CI 1.04 to 1.57) compared with NHA patients. Composite morbidity was similar between NHA and HA patients with predischarge SSIs (aOR 1.06; 95% CI 0.56 to 2.00) or who were discharged >5 days post operation (aOR 1.14; 95% CI 0.89 to 1.46). CONCLUSIONS: Although the majority of pediatric patients with complicated appendicitis are discharged with HA, NSQIP-Pediatric data suggest there is no evidence of a significant benefit. There might be a cohort of patients with more severe disease who require continued antibiotics.

BACKGROUND/PURPOSE: Surgical site infection (SSI) rate in pediatric appendicitis is a commonly used hospital quality metric. We hypothesized that surveillance of organ-space SSI (OSI) using cultures alone would fail to capture many clinically-important events. METHODS: A prospective, multidisciplinary surveillance program recorded 30-day SSI and hospital length of stay (LOS) for patients <18years undergoing appendectomy for perforated appendicitis from 2012 to 2015. Standardized treatment pathways were utilized, and OSI was identified by imaging and/or bacterial cultures. RESULTS: Four hundred ten appendectomies for perforated appendicitis were performed, and a total of 84 OSIs (20.5%) were diagnosed with imaging. Positive cultures were obtained for 39 (46%) OSIs, whereas 45 (54%) had imaging only. Compared to the mean LOS for patients without OSI (5.2±2.9days), LOS for patients with OSI and positive cultures (13.7±5.4days) or with OSI without cultures (10.4±3.7days) was significantly longer (both p<0.001). The OSI rate identified by positive cultures alone was 9.5%, whereas the clinically-relevant OSI rate was 20.5%. CONCLUSIONS: Using positive cultures alone to capture OSI would have identified less than half of clinically-important infections. Utilizing clinically-relevant SSI is an appropriate metric for comparing hospital quality but requires agreed upon standards for diagnosis and reporting. LEVEL OF EVIDENCE: II. TYPE OF STUDY: Diagnostic study.

This study evaluated the efficacy of education versus audit and feedback in decreasing vancomycin utilization. Data were collected prospectively from October 1, 2012-April 30, 2014 over the following 3 periods: baseline, after education and introduction of a late-onset sepsis treatment guideline, and after prospective audit-feedback to physicians. Vancomycin utilization and administration duration >3 days significantly decreased with education and guideline use, but it was not affected by addition of audit and feedback.

BACKGROUND/PURPOSE: Surgical wound class (SWC) is used to risk-stratify surgical site infections (SSI) for quality reporting. We previously demonstrated only 8% agreement between hospital-based SWC and diagnosis-based SWC for acute appendicitis. We hypothesized that education and process-based interventions would improve hospital-based SWC reporting and the validity of SSI risk stratification. METHODS: Patients (<18 years old) who underwent appendectomies for acute appendicitis between January 2011 and December 2013 were included. Interventions entailed educational workshops regarding SWC for perioperative personnel and inclusion of SWC as a checkpoint in the surgical safety checklist. Thirty-day postoperative SSIs were recorded. Chi-square, Fisher's exact test, and kappa statistic were utilized. RESULTS: 995 cases were reviewed (pre-intervention=478, post-intervention=517). Weighted interrater agreement between hospital-based and diagnosis-based SWC improved from 50% to 81% (p<0.01), and weighted kappa increased from 0.16 (95% CI 0.004-0.03) to 0.29 (95% CI 0.25-0.34). Hospital-based dirty wounds were significantly associated with SSI in the post-intervention period only (p<0.01). CONCLUSIONS: Agreement between hospital-based SWC and diagnosis-based SWC significantly improved after simple interventions, and SSI risk stratification became consistent with the expected increase in disease severity. Despite these improvements, there were still substantial gaps in SWC knowledge and process.

BACKGROUND: The impact of quality measures in health care and reimbursement is growing. Ensuring the accuracy of quality measures, including any risk-stratification variables, is necessary. Surgical site infection rates, risk stratified by surgical wound classification (SWC) among other variables, are increasingly considered as quality measures. We hypothesized that hospital-documented and diagnosis-based SWCs are frequently discordant and that diagnosis-based SWCs better predict surgical site infection rates. STUDY DESIGN: All pediatric patients (ie, younger than 18 years old) at a single institution who underwent an appendectomy for appendicitis between October 1, 2010 and August 31, 2011 were included. Each chart was reviewed to determine the hospital-documented SWC, which is recorded by the circulating nurse (options included clean, clean-contaminated, contaminated, and dirty); SWC based on the surgeons' postoperative diagnosis, including contaminated (ie, acute nonperforated, nongangrenous appendicitis), dirty (ie, gangrenous and perforated appendicitis), and 30-day postoperative surgical site infections. RESULTS: Of the 312 evaluated appendicitis cases, the diagnosis-based and circulating nurse-based SWCs differed in 288 (92%) cases. The circulating nurse-based and diagnosis-based SWCs differed by more than one SWC in 176 (56%) cases. Surgical site infections were associated with worsening diagnosis-based SWC, but not with circulating nurse-based SWC. CONCLUSIONS: Significant discordance exists between hospital documentation by the circulating nurse- and surgeon diagnosis-based SWCs. Inconsistency in risk-stratified quality measures can have a significant effect on outcomes measures, which can lead to misdirection of quality-improvement efforts, incorrect inter-hospital rating, reduced reimbursements, and public misperceptions about quality of care.

OBJECTIVE: To determine whether active surveillance culturing for methicillin-resistant Staphylococcus aureus (MRSA) decreases nosocomial MRSA acquisition in the pediatric intensive care unit. DESIGN: Before and after observational study. SETTING: A tertiary care, 20-bed, pediatric intensive care unit. PATIENTS: All patients admitted to the pediatric intensive care unit. INTERVENTIONS: Anterior nares cultures for MRSA were obtained on admission and weekly in the pediatric intensive care unit from January 2007 to December 2009 as part of a hospital quality improvement project. MEASUREMENTS AND MAIN RESULTS: MRSA admission prevalence and nosocomial incidence density were determined retrospectively for 2006 and prospectively for 2007-2009. Nosocomial MRSA incidence density during the intervention period was determined monthly and analyzed by trend analysis by using a general linear model. The correlation of active surveillance culturing compliance with nosocomial acquisition of MRSA was analyzed. Possible confounding by healthcare worker hand hygiene compliance observed during the intervention period was also analyzed by multivariate linear regression analysis. The yearly MRSA incidence density significantly decreased from 2006 to 2009 (6.88 per 1,000 patient days to 1.45 per 1,000 patient days, p < .001) and from 2007 to 2009 (7.32 per 1,000 patient days to 1.45 per 1,000 patient days, p < .001). Trend analysis demonstrated a significant decline in MRSA acquisition over time following the introduction of active surveillance culturing (p < .001). Surveillance culturing was significantly associated with the decline in MRSA acquisition observed in the pediatric intensive care unit by multivariate regression analysis when controlling for hand hygiene (p = .01). CONCLUSIONS: Active surveillance culturing resulted in significantly decreased nosocomial acquisition of MRSA in a pediatric intensive care unit setting. Admission and weekly active surveillance culturing appears to be an effective tool to decrease the spread of MRSA in the pediatric intensive care unit, independent of improvement in hand hygiene compliance. The impact on hospital-acquired MRSA infections and the cost benefit of active surveillance culturing require further study.

A retrospective case-control study was performed to determine the risks and outcomes associated with pediatric cardiothoracic surgical site infection. Undergoing more than 1 cardiothoracic operative procedure, having preoperative infection, and undergoing surgery on a Monday were significant risk factors. Cardiothoracic surgical site infection increased hospital and pediatric intensive care unit length of stay. Deep surgical site infection significantly increased mortality.

OBJECTIVES: In August 2005, the Centers for Disease Control and Prevention was notified of a Ralstonia species outbreak among pediatric patients receiving supplemental oxygen therapy with the Vapotherm 2000i (Vapotherm, Inc, Stevensville, MD). The Vapotherm 2000i is a reusable medical device that was used in >900 hospitals in the United States in 2005. Ralstonia are waterborne bacilli that have been implicated in hospital-acquired infections. We initiated an investigation to determine the source of the outbreak and implement infection control and prevention measures. PATIENTS AND METHODS: We performed a case-control study at 1 hospital and conducted national case findings to obtain clinical and environmental samples for laboratory analysis. Case-patients had health care-acquired Ralstonia colonization or infection. Isolates were compared by using pulsed-field gel electrophoresis. We tested manufacturer-recommended disinfection protocols for the Vapotherm 2000i under simulated-use conditions. RESULTS: Case-patients at the hospital (n = 5) were more likely to have received Vapotherm therapy than controls. Nationally, Ralstonia mannitolilytica was confirmed in 38 patients (aged 5 days to 7 years); 35 (92%) of the patients were exposed to the Vapotherm 2000i before recovery of the organism. Pulsed-field gel electrophoresis showed related R. mannitolilytica strains from isolates sent from 18 hospitals in 12 states. A Vapotherm machine reprocessed with a protocol proposed by the manufacturer grew Ralstonia spp after 7 days of simulated use. In December 2005, Vapotherm recalled the 2000i. CONCLUSIONS: Our findings suggest intrinsic contamination of Vapotherm devices with Ralstonia spp. New medical devices may provide therapy equivalent to current devices yet pose novel reprocessing challenges.

OBJECTIVE: To determine the source of an outbreak of Salmonella javiana infection. DESIGN: Case-control study. PARTICIPANTS: A total of 101 culture-confirmed cases and 540 epidemiologically linked cases were detected between May 26, 2003, and June 16, 2003, in hospital employees, patients, and visitors. Asymptomatic employees who had eaten in the hospital cafeteria between May 30 and June 4, 2003, and had had no gastroenteritis symptoms after May 1, 2003, were chosen as control subjects. SETTING: A 235-bed academic tertiary care children's hospital. RESULTS: Isolates from 100 of 101 culture-confirmed cases had identical pulsed-field gel electrophoresis patterns. A foodhandler with symptoms of gastroenteritis was the presumed index subject. In multivariate analysis, case subjects were more likely than control subjects to have consumed items from the salad bar (adjusted odds ratio [aOR], 5.3; 95% confidence interval [CI], 2.3-12.1) and to have eaten in the cafeteria on May 28 (aOR, 9.4; 95% CI, 1.8-49.5), May 30 (aOR, 3.6; 95% CI, 1.0-12.7), and/or June 3 (aOR, 4.0; 95% CI, 1.4-11.3). CONCLUSIONS: Foodhandlers who worked while they had symptoms of gastroenteritis likely contributed to the propagation of the outbreak. This large outbreak was rapidly controlled through the use of an incident command center.

OBJECTIVE: To evaluate antimicrobial use and the influence of inadequate empiric antimicrobial therapy on the outcomes of nosocomial bloodstream infections (BSIs). DESIGN: Prospective cohort study with nested case-control analysis. SETTING: Neonatal intensive care unit (NICU). METHODS: All patients weighing 2,000 g or less were enrolled. Data collection included risk factors for nosocomial BSI, admission severity of illness, microbiology, antimicrobial therapy, and outcomes. Inadequate empiric antimicrobial therapy was defined as the use of antibiotics for more than 48 hours after the day that blood cultures were performed that did not cover the microorganisms causing the bacteremia or administration of antibiotics that failed to cover resistant microorganisms. RESULTS: Two hundred twenty-nine patients were enrolled. Forty-five developed nosocomial BSIs. The BSI rates were 11.2, 2.8, and 0 per 1,000 catheter-days for patients weighing 1,000 g or less, between 1,001 and 1,500 g, and between 1,501 and 2,000 g, respectively. After adjustment for severity of illness, the mortality in patients with nosocomial BSI receiving inadequate empiric antimicrobial therapy was higher than in those receiving adequate therapy (adjusted odds ratio [AOR], 5.3; 95% confidence interval [CI95], 1.2-23.2). By multivariate analysis, nosocomial BSI attributed to Candida species (AOR, 6.3; CI95, 1.4-28.0) and invasive procedure prior to onset of BSI (AOR, 6.4; CI95, 1.0-39.0) were associated with administration of inadequate empiric antimicrobial therapy. CONCLUSIONS: Administration of inadequate empiric antimicrobial therapy among NICU patients with nosocomial BSI was associated with higher mortality. Additional studies on the role of inadequate empiric antimicrobial therapy and the outcomes of BSIs among NICU patients are needed.
