Introduction: Antibiotic stewardship programs (ASP) improve appropriate antibiotic use. Data are limited on the clinical benefit of ASPs in children's hospitals. This study's objective was to determine the impact of an ASP on length of stay (LOS) and readmission rate among patients admitted to children's hospitals., Methods: Data from a prospective-audit-with-feedback ASP were used to examine the ASP review characteristics, including antibiotic(s) prescribed, clinical indication, recommendations made by the ASP, and agreement with recommendations. Propensity score analysis was utilized to determine the impact of the ASP on LOS and 30-day readmission based on whether the patient received an ASP recommendation and if the clinician agreed with recommendations. Patients were stratified on if they had a complex chronic condition status (CCC) and their service line, medical or surgical., Results: Of the 8038 reviews included, 1362 (16.9%) resulted in a recommendation that was agreed with in 1116 (81%) cases. Propensity score analysis demonstrated a significantly longer LOS for the non-CCC medicine group who received an ASP recommendation (80.9 vs. 67.6 h, p < 0.001). However, for CCC medicine patients that agreed with the ASP recommendation, a clinically relevant decrease in LOS (158.1 vs. 180.3 h, p = 0.095) was observed. The 30-day readmission rate was significantly greater in CCC medicine patients when comparing those who did not receive a recommendation versus those who did receive a recommendation (7.3% vs 4.2%, respectively; p = 0.005)., Conclusion: Children without a CCC who received an ASP recommendation had a longer length of stay. For children with CCCs, the ASP appeared to decrease LOS and significantly reduce 30-day readmission rates. Overall, this study demonstrate that ASPs offer meaningful clinical benefit justifying resource allocation needed to develop and maintain ASP programs.

Background: The emergence of antibiotic-resistant organisms and the lack of development of new antimicrobials have made it imperative that additional strategies be developed to maintain the effectiveness of these existing antibiotics. The objective of this study was to describe the impact of a prospective-audit-with-feedback antimicrobial stewardship program (ASP) on antibiotic use in a children's hospital., Method: A quasi-experimental study design with a control group was performed to assess the impact of a prospective-audit-with-feedback ASP. The control group was the combined antibiotic use at 25 similar children's hospitals that are members of the Child Health Corporation of America., Results: The ASP reviewed 10 460 broad-spectrum or select antibiotics in 8765 patients in the 30 months following the intervention. The most common select antibiotics reviewed were ceftriaxone/cefotaxime (43%), vancomycin (18%), ceftazidime (12%), and meropenem (7%). A total of 2378 recommendations were made in 1703 (19%) patients; the most common recommendation was to stop antibiotics (41%). Clinicians were compliant with agreed-upon ASP recommendations in 92% of patients. When comparing our antibiotic use with that of the control group, a monthly decline in all antibiotics of 7% (P = .045) and 8% (P = .045) was observed for days of therapy (DoT) and length of therapy (LoT) per 1000 patient-days, respectively. An even greater effect was observed in the select antibiotics as the monthly DoT per 1000 patient-days declined 17% (P < .001) and the monthly LoT per 1000 patient-days declined 18% (P < .001)., Conclusions: A prospective-audit-with-feedback ASP can have a significant impact on decreasing antibiotic use at a children's hospital., (© The Author 2012.

Accurate information about deaths is important when determining the human health and economic burden of foodborne diseases. We reviewed death certificate data to assess the accuracy of deaths reported to the Foodborne Diseases Active Surveillance Network (FoodNet). Data were highly accurate, and few deaths were missed through active surveillance.

Background: Raw produce is an increasingly recognized vehicle for salmonellosis. We investigated a nationwide outbreak that occurred in the United States in 2008., Methods: We defined a case as diarrhea in a person with laboratory-confirmed infection with the outbreak strain of Salmonella enterica serotype Saintpaul. Epidemiologic, traceback, and environmental studies were conducted., Results: Among the 1500 case subjects, 21% were hospitalized, and 2 died. In three case-control studies of cases not linked to restaurant clusters, illness was significantly associated with eating raw tomatoes (matched odds ratio, 5.6; 95% confidence interval [CI], 1.6 to 30.3); eating at a Mexican-style restaurant (matched odds ratio, 4.6; 95% CI, 2.1 to ∞) and eating pico de gallo salsa (matched odds ratio, 4.0; 95% CI, 1.5 to 17.8), corn tortillas (matched odds ratio, 2.3; 95% CI, 1.2 to 5.0), or salsa (matched odds ratio, 2.1; 95% CI, 1.1 to 3.9); and having a raw jalapeño pepper in the household (matched odds ratio, 2.9; 95% CI, 1.2 to 7.6). In nine analyses of clusters associated with restaurants or events, jalapeño peppers were implicated in all three clusters with implicated ingredients, and jalapeño or serrano peppers were an ingredient in an implicated item in the other three clusters. Raw tomatoes were an ingredient in an implicated item in three clusters. The outbreak strain was identified in jalapeño peppers collected in Texas and in agricultural water and serrano peppers on a Mexican farm. Tomato tracebacks did not converge on a source., Conclusions: Although an epidemiologic association with raw tomatoes was identified early in this investigation, subsequent epidemiologic and microbiologic evidence implicated jalapeño and serrano peppers. This outbreak highlights the importance of preventing raw-produce contamination.

Salmonella is the most common bacterial cause of foodborne outbreaks in the United States. Starting in June 2007, investigation of a cluster of Salmonella Montevideo cases with indistinguishable pulsed-field gel electrophoresis (PFGE) patterns resulted in the identification of an outbreak associated with contact with chickens purchased from a single hatchery. Nine Minnesota cases from May through August 2007 were part of this outbreak. Cases with the outbreak PFGE pattern of Salmonella Montevideo continued to occur in Minnesota after August, but none of these cases reported chicken contact. The majority of these cases resided in the same town in rural Minnesota. Routine interviews revealed that all cases from these counties purchased groceries from the same local grocery store, with two specifically reporting consuming items from the grocery store delicatessen in the week before illness. As a result, an investigation into the delicatessen was initiated. Illness histories and stool samples were collected from all delicatessen employees, and food and environmental samples were collected. None of the employees reported experiencing recent gastrointestinal symptoms, but the outbreak PFGE subtype of Salmonella Montevideo was identified from stool from two food workers. Food and environmental samples collected tested negative for Salmonella. One of the positive employees reported having chickens at home, but the animals did not test positive for Salmonella. The positive food workers were excluded from work until they had two consecutive negative stool cultures for Salmonella. There was no evidence of ongoing transmission thereafter. This was an outbreak of Salmonella Montevideo infections that began as an animal-contact-associated outbreak which subsequently resulted in a foodborne outbreak associated with infected food workers. These outbreaks illustrate the complex epidemiology of salmonellosis.

Salmonella is the most common bacterial cause of foodborne outbreaks in the United States; approximately half of Salmonella outbreaks occur in restaurant settings. In February 2008, investigation of a cluster of Salmonella Enteritidis cases with indistinguishable pulsed-field gel electrophoresis (PFGE) patterns revealed that five cases had eaten at the same restaurant. Cases were identified through routine surveillance activities and by contacting meal companions of culture-confirmed cases. Well meal companions and well patrons contacted via check stubs served as controls. Illness histories and stool samples were collected from all restaurant employees. Sandwiches were the only menu item or ingredient significantly associated with illness (15 of 15 cases versus 17 of 37 controls; odds ratio, undefined; P < 0.001). None of the six restaurant employees reported experiencing recent gastrointestinal symptoms. The outbreak PFGE subtype of Salmonella Enteritidis was identified in two food workers. One of the positive employees began working at the restaurant shortly before the first exposure date reported by a case, and assisted in the preparation of sandwiches and other foods consumed by cases. The other positive employee rarely, if ever, handled food. The restaurant did not have a glove use policy. There was no evidence of ongoing transmission after exclusion of the positive food workers. This was a restaurant Salmonella Enteritidis outbreak associated with an asymptomatic infected food worker. Routine PFGE subtyping of Salmonella Enteritidis isolates, routine interviewing of cases, and an iterative approach to cluster investigations allowed for timely identification of the source of an outbreak of Salmonella Enteritidis infections.
