Background/Purpose. Whether decolonization following incision and drainage (I&D) for methicillin-resistant Staphylococcus aureus (MRSA) abscess decreases repeat I&D and MRSA-positive cultures in children is unknown. Materials/Methods. Referral to the Pediatric Infectious Disease Service (PIDS) for decolonization was determined for eligible children (2003-2010), with outcomes studied over 12 months. Results. We identified 653 children; 54 had been seen by PIDS. In the PIDS group, no patients (0/54, 0%) had a repeat I&D. In the no PIDS group 36/599 (6%) had a repeat I&D, P = .06. Logistic regression modeling for repeat I&D showed no significant effect, odds ratio = 0.29; 95% confidence interval = 0.04-2.15; P = .23. In the PIDS group, 3 patients (3/54, 5.6%) had a repeat MRSA-positive culture. In the no PIDS group, 58/599 (9.7%) had a positive repeat culture, P = .46. Logistic regression modeling for positive culture showed no significant effect (odds ratio = 0.55; 95% confidence interval = 0.17-1.81; P = .32). Conclusions. We detected no statistically significant association between decolonization and repeat I&D or MRSA-positive culture.

Background/Purpose Management of asymptomatic neonatal ovarian cysts varies. Some surgeons advocate initial observation, while others recommend immediate operation depending on cyst size and complexity. This study aims to compare outcomes of initial observation versus primary surgery, focusing on incidence of postnatal torsion and ovarian preservation. Methods A retrospective study (1997–2012) of neonates with an ovarian mass was performed. Data on cyst size, ultrasound characteristics, clinical course, complications, and pathology were extracted. Results Thirty-seven neonates with asymptomatic ovarian cysts were identified (N=25 observed, N=12 primary surgery). Overall, 12/25 (48%) observed had successful cyst regression, including 3/8 (38%) cysts ≥50mm and 6/15 (40%) complex. 13/25 patients (52%) underwent surgery for failure of cyst regression (11/13) or concern for interval torsion (2/13). Postnatal torsion occurred in 1/25 observation patients (4%), or 1/8 (13%) with cysts≥50mm. Overall rate of ovarian preservation between groups was not statistically different [6/8 (75%) observed versus 8/9 (89%) primary surgery; P=0.577]. Pathology found viable ovarian tissue in all oophorectomy specimens (N=3). Conclusions Postnatal torsion is rare. A period of observation spares half of neonates from an operation, without decreasing ovarian salvage. Initial management should consist of observation, regardless of size or complex characteristics. If operative intervention is necessary, ovary preserving techniques should be utilized.

Anticipated postoperative pain may affect procedure choice in patients with pectus excavatum. This study aims to compare postoperative pain in patients undergoing Nuss and Ravitch procedures.A 5year retrospective review was performed. Data on age, gender, Haller index, procedure, pain scores, pain medications, and length of hospital stay were collected. Total inpatient opioid administration was converted to morphine equivalent daily dose per kilogram (MEDD/kg) and compared between procedures.One hundred eighty-one patients underwent 125 (69%) Nuss and 56 (31%) Ravitch procedures. Ravitch patients were older (15.7 yo vs 14.6 yo, p=0.004) and had a higher Haller index (5.21 vs 4.10, p=0.001). Nuss patients had higher average daily pain scores, received 25% more opioids (MEDD/kg 0.66 vs. 0.49, p=0.001), and received twice as much IV diazepam/kg. In the multivariate analysis, higher MEDD/kg correlated with both the Nuss procedure and older age in the Nuss group. Opioid administration did not correlate with Haller index or Nuss bar fixation technique. Increased NSAID administration did not correlate with lower use of opioids.The Nuss procedure is associated with greater postoperative pain compared to the Ravitch procedure. Opioid use is higher in older patients undergoing the Nuss procedure, but is not associated with severity of deformity.

OBJECTIVE: To evaluate whether admission day of the week affects the length of stay (LOS) and health care costs for failure to thrive (FTT) admissions. METHODS: Administrative data were obtained for all children aged RESULTS: Weekend admission was significantly correlated with increased LOS and increased average cost (P < .002). This finding was also true for children with both admission and discharge diagnoses of FTT (P < .001). The number of procedures for children admitted on the weekend was not significantly different compared with children admitted on the weekdays (incident rate ratio [IRR]:1.04 [95% confidence interval (CI): 0.99–1.09]). However, weekend admissions did have more radiologic studies (IRR: 1.13 [95% CI: 1.10–1.16]) and laboratory tests (IRR: 1.39 [95% CI: 1.38–1.40]) performed. If one-half of weekend admissions in 2010 with both admission and discharge diagnoses of FTT were converted to Monday admissions, total savings in health care dollars for 2010 would be $534, 145. CONCLUSIONS: Scheduled FTT admissions on weekends increased LOS and health care costs compared with weekday admissions of similar levels of complexity. Reduction in planned weekend admissions for FTT could significantly reduce health care costs.

Esophageal atresia/tracheoesophageal fistula (EA/TEF) is a rare congenital anomaly lacking contemporary data detailing patient demographics, medical/surgical management and outcomes. Substantial variation in the care of infants with EA/TEF may affect both short- and long-term outcomes. The purpose of this study was to characterize the demographics, management strategies and outcomes in a contemporary multi-institutional cohort of infants diagnosed with EA/TEF to identify potential areas for standardization of care.A multi-institutional retrospective cohort study of infants with EA/TEF treated at 11 children's hospitals between 2009 and 2014 was performed. Over the 5year period, 396 cases were identified in the 11 centers (7±5 per center per year). All infants with a diagnosis of EA/TEF made within 30days of life who had surgical repair of their defect defined as esophageal reconstruction with or without ligation of TEF within the first six months of life were included. Demographic, operative, and outcome data were collected and analyzed to detect associations between variables.Prenatal suspicion or diagnosis of EA/TEF was present in 53 (13%). The most common anatomy was proximal EA with distal TEF (n=335; 85%) followed by pure EA (n=27; 7%). Clinically significant congenital heart disease (CHD) was present in 137 (35%). Mortality was 7.5% and significantly associated with CHD (p0.0001). Postoperative morbidity occurred in 62% of the population, including 165 (42%) cases with anastomotic stricture requiring intervention, anastomotic leak in 89 (23%), vocal cord paresis/paralysis in 26 (7%), recurrent fistula in 19 (5%), and anastomotic dehiscence in 9 (2%). Substantial variation in practice across our institutions existed: bronchoscopy prior to repair was performed in 64% of cases (range: 0%-100%); proximal pouch contrast study in 21% (0%-69%); use of interposing material between the esophageal and tracheal suture lines in 38% (0%-69%); perioperative antibiotics ≥24h in 69% (36%-97%); and transanastomotic tubes in 73% (21%-100%).Contemporary treatment of EA/TEF is characterized by substantial variation in perioperative management and considerable postoperative morbidity and mortality. Future studies are planned to establish best practices and clinical care guidelines for infants with EA/TEF.Type of study: Treatment study. Level IV.

OBJECTIVES We sought to determine whether practice differences for fundoplication exist between 2 geographically distinct states, and to determine the reflux medication use pattern associated with concomitant fundoplication. METHODS A retrospective observational cohort study of children in Colorado (CO) and North Carolina (NC) insured by Medicaid from 2006 to 2008. Children who received a surgical gastrostomy during the study period were included, and our primary outcome measure was the performance of a concomitant gastric fundoplication. Thirty-day prescription fills for reflux medications were examined before and after gastrostomy procedure. RESULTS We examined 969 surgical gastrostomy admission in both states over the 3-year study period (CO, n = 341 and NC, n = 628). Patients in each state had similar age (median age, 6 months, P = 0.97). Use of pH probe (CO: 15%, NC: 11%) and diagnosis of reflux (CO: 84%, NC: 72%) differed in each state. Concomitant fundoplication was performed in 60% of patients in CO and 43% in NC (P

Background Standard gamble (SG) and time trade-off (TTO) are two methods used for obtaining health utility values (utilities). Whether the order in which the methods are applied alters the relative utilities obtained by each method is unknown. Objective We sought to determine whether the order in which SG and TTO utilities were obtained affects the relative values of the utilities obtained by each technique. Methods Utilities were assessed for 29 health states from 4016 parents by using SG and TTO. The assessment order was randomized by respondent. For analysis by health state, we calculated (SG –TTO) for each assessment and tested whether the SG – TTO difference was significantly different between the two groups (SG first and TTO first). For analysis by individual, we calculated a risk-posture coefficient, γ , defined by the utility curve, SG=TTO γ . We predicted γ through regression analysis with the covariates: child age, child sex, birth order, respondent age, respondent education level, and assessment method order. Results In 19 of 29 health states, the SG − TTO difference was significantly greater (more risk averse) when TTO was assessed first. In the regression analysis, "child age" and "assessment method order" were significant predictors of risk attitude. The risk posture coefficient γ was higher (more risk-seeking) with increasing child age and in the SG-first respondents. Conclusion The order in which the SG versus TTO method is used strongly influences the relative values of the utilities obtained.

Economic analyses, such as cost-utility analyses (CUAs), are dependent on the quality of the data used. Our objective was to test how health utility values (measurements of patient preference) assessed by recommended methods (classic utilities) would impact the conclusions in published pediatric CUAs.Classic utilities for pediatric health states were obtained by recommended utility assessment methods, time trade-off, and standard gamble in 4016 parent interviews. To test the impact of these utilities on published studies, we obtained a sample of published pediatric CUAs by searching Medline, EMBASE, EconLit, Health Technology Assessment Database, Cochrane Database on Systematic Reviews, Database of Abstracts of Reviews of Effects, and the Cost Effective Analysis (CEA) Registry at Tufts Medical Center, using search terms for cost-utility analysis. Articles were included when results were presented as cost per quality adjusted life-years (QALYs), the interventions were for children18 years of age and included at least one of the following health states: attention deficit hyperactivity disorder, asthma, gastroenteritis, hearing loss, mental retardation, otitis media, seizure disorder, or vision loss. Studies that did not include these or equivalent health states were excluded. For each CUA, we determined utilities (values for patient preference), the utility assessment method used, and presence of one-way sensitivity analyses (SAs) on utilities. When one-way SAs were conducted, we determined if using our classic utilities would change the result of the CUA. When an SA was not presented, we determined if using our classic utilities would tend to support or not support the published conclusions.We evaluated 39 articles. Eighteen articles presented results of one-way SAs on utilities. Seven articles presented SAs over a range that included our classic utilities. In 4 of the 7, using classic utilities would change the conclusion of the study. For the 32 articles where no one-way SA were presented (n = 21), or where the classic utilities fell outside the range tested (n =11), a change to classic utility would tend against the study conclusion in 12 articles (31%).More than a third of published CUA studies could change if pediatric utilities obtained by recommended, classic methods were used. One-way SAs on utilities are often not presented, making comparison between studies challenging.

OBJECTIVES: The diagnosis and management of urinary tract infections (UTIs) in young children are clinically challenging. This report was developed to inform the revised, evidence-based, clinical guideline regarding the diagnosis and management of initial UTIs in febrile infants and young children, 2 to 24 months of age, from the American Academy of Pediatrics Subcommittee on Urinary Tract Infection. METHODS: The conceptual model presented in the 1999 technical report was updated after a comprehensive review of published literature. Studies with potentially new information or with evidence that reinforced the 1999 technical report were retained. Meta-analyses on the effectiveness of antimicrobial prophylaxis to prevent recurrent UTI were performed. RESULTS: Review of recent literature revealed new evidence in the following areas. Certain clinical findings and new urinalysis methods can help clinicians identify febrile children at very low risk of UTI. Oral antimicrobial therapy is as effective as parenteral therapy in treating UTI. Data from published, randomized controlled trials do not support antimicrobial prophylaxis to prevent febrile UTI when vesicoureteral reflux is found through voiding cystourethrography. Ultrasonography of the urinary tract after the first UTI has poor sensitivity. Early antimicrobial treatment may decrease the risk of renal damage from UTI. CONCLUSIONS: Recent literature agrees with most of the evidence presented in the 1999 technical report, but meta-analyses of data from recent, randomized controlled trials do not support antimicrobial prophylaxis to prevent febrile UTI. This finding argues against voiding cystourethrography after the first UTI.

Purpose. To determine effectiveness of prophylactic antibiotics in preventing cholangitis, we conducted a systematic review comparing cholangitis occurrence in biliary atresia patients after Kasai portoenterostomy (KP) with and without antibiotics. Methods. We searched online bibliographic databases from April 1, 2013, using search terms “biliary atresia” OR “cholangitis” AND “antibiotics,” selecting studies with control group data. Results. Four of 509 titles met inclusion criteria, yielding a total of 319 patients from 3 countries. Three studies were retrospective cohorts and one was a randomized clinical trial. Two cohort studies concluded that prophylactic antibiotics reduced incidence of cholangitis and one did not. The randomized clinical trial supported prophylaxis after comparing the prospective randomized groups to a historical control group. Conclusion. Few published studies measure the effect of prophylactic antibiotics after Kasai portoenterostomy. We identified 4 studies and they presented contradictory results. Prospective research is needed.

Objective.To build and to begin evaluating a regional automated system to notify infection preventionists (IPs) when a patient with a history of gram-negative rod multidrug-resistant organism (GNRMDRO) is admitted to an emergency department (ED) or inpatient setting.Design.Observational, retrospective study.Setting.Twenty-seven hospitals, mostly in the Indianapolis metropolitan area, in a health information exchange (HIE).Patients.During testing of the new system: 80,180 patients with microbiology cultures between October 1, 2013, and December 31, 2013; 573 had a GNRMDRO.Methods/Intervention.A Health Level Seven (HL7) data feed from the HIE was obtained, corrected, enhanced, and used for decision support (secure e-mail notification to the IPs). Retrospective analysis of patients with microbiology data (October 1, 2013, through December 31, 2013) and subsequent healthcare encounters (through February 6, 2014).Results.The 573 patients (median age, 66 years; 68% women) had extended-spectrum β-lactamase-producing Enterobacteriaceae (78%), carbapenem-resistant Enterobacteriaceae (7%), Pseudomonas aeruginosa (9%), Acinetobacter baumannii (3%), or other GNR (3%). Body sources were urine (68%), sputum/trachea/bronchoalveolar lavage (13%), wound/skin (6%), blood (6%), or other/unidentified (7%). Between October 1, 2013, and February 6, 2014, 252 (44%) of 573 had an ED or inpatient encounter after the GNRMDRO culture, 47 (19% of 252) at an institution different from where the culture was drawn. During the first 7 weeks of actual alerts (January 29, 2014, through March 19, 2014), alerts were generated regarding 67 patients (19 of 67 admitted elsewhere from where the culture was drawn).Conclusions.It proved challenging but ultimately feasible to create a regional microbiology-based alert system. Even in a few months, we observed substantial crossover between institutions. This system, if it contributes to timely isolation, may help reduce the spread of GNRMDROs.

BACKGROUND AND OBJECTIVE: Emphasizing societal benefits of vaccines has been linked to increased vaccination intentions in adults. It is unclear if this pattern holds for parents deciding whether to vaccinate their children. The objective was to determine whether emphasizing the benefits of measles-mumps-rubella (MMR) vaccination directly to the vaccine recipient or to society differentially impacts parents' vaccine intentions for their infants. METHODS: In a national online survey, parents (N = 802) of infants RESULTS: Compared with the VIS-only group (mean intention = 86.3), parents reported increased vaccine intentions for their infants when receiving additional information emphasizing the MMR vaccine’s benefits either directly to the child (mean intention = 91.6, P = .01) or to both the child and society (mean intention = 90.8, P = .03). Emphasizing the MMR vaccine’s benefits only to society did not increase intentions (mean intention = 86.4, P = .97). CONCLUSIONS: We did not see increases in parents’ MMR vaccine intentions for their infants when societal benefits were emphasized without mention of benefits directly to the child. This finding suggests that providers should emphasize benefits directly to the child. Mentioning societal benefits seems to neither add value to, nor interfere with, information highlighting benefits directly to the child.

Background Rates of anti-reflux procedures (ARP) vary greatly among pediatric hospitals. How pediatric subspecialists make referral decisions for ARPs has not been described. The aim of this study was to characterize pediatric subspecialists' decision making for referring children for ARPs. Methods Pediatric subspecialists at a single children's hospital were interviewed about their decision making when referring for ARPs. Qualitative analysis was performed on clinicians' perceptions of the risks and benefits of the treatment options. Clinical algorithms were derived from each interview and were compared using the Clinical Algorithm Nosology. Clinical Algorithm Structural Analysis (CASA) scores were calculated to assess algorithm complexity. Clinical Algorithm Patient Abstraction (CAPA) scores on a scale from 0 (different) to 10 (identical) were generated based on algorithm agreement. Results The interviews yielded 15 algorithms. There was substantial variation in the providers' perceived risks and benefits of the treatment options. CASA scores ranged from 8 to 28 and CAPA scores ranged from 0 to 5.7 (median, 0), indicating great variation in both complexity and patient management. Management variation included testing (33% of algorithms incorporated pH probe test, 67% upper gastrointestinal, and 47% small bowel follow-through), procedure contraindications (33% considered history of gagging a contraindication to ARP), and use of gastrojejunostomy tubes (20% using gastrojejunostomy tube before ARP). Conclusion No standards exist for the decision to refer children with gastroesophageal reflux disease for ARP. There is great variation among pediatric subspecialists in their decision making. Differences in providers' perception of the risks and benefits of these procedures contribute to this variation.

Ovarian preservation is desirable in girls with benign ovarian masses. We aimed to 1) identify clinical predictors of malignant ovarian masses, 2) investigate how often ovarian tissue is present to preserve in benign masses, and 3) identify factors associated with successful ovarian preservation.Retrospective analysis (1997-2012) of girls age 1-18years with an ovarian mass managed operatively. Data on presenting symptoms, imaging, biochemical markers, treatment, outcome, and pathology were extracted.We identified 150 patients. Large mass size, solid components, and elevated tumor markers (AFP, βHCG, and/or LDH) were significantly predictive of malignancy. All masses10cm, predominantly cystic, and with negative tumor markers were benign. Masses with all three of these characteristics would decrease a 20% malignancy pretest probability to a posttest probability of 0.25%. Benign masses managed by oophorectomy contained normal ovarian tissue in 76% of the specimens. For benign masses, successful ovarian preservation was significantly associated with size10cm, predominantly cystic, laparoscopy, and absence of torsion or calcifications.Ovarian masses that are10cm, primarily cystic, and have negative tumor markers are most likely benign. Viable ovarian tissue is frequently present in benign masses, so significant efforts should be made for ovarian preservation.

BACKGROUND AND OBJECTIVE: Herd immunity is an important benefit of childhood immunization, but it is unknown if the concept of benefit to others influences parents’ decisions to immunize their children. Our objective was to determine if the concept of “benefit to others” has been found in the literature to influence parents’ motivation for childhood immunization. METHODS: We systematically searched Medline through October 2010 for articles on parental/guardian decision-making regarding child immunization. Studies were included if they presented original work, elicited responses from parents/guardians of children RESULTS: The search yielded 5876 titles; 91 articles were identified for full review. Twenty-nine studies met inclusion criteria. Seventeen studies identified benefit to others as 1 among several motivating factors for immunization by using interviews or focus groups. Nine studies included the concept of benefit to others in surveys but did not rank its relative importance. In 3 studies, the importance of benefit to others was ranked relative to other motivating factors. One to six percent of parents ranked benefit to others as their primary reason to vaccinate their children, and 37% of parents ranked benefit to others as their second most important factor in decision-making. CONCLUSIONS: There appears to be some parental willingness to immunize children for the benefit of others, but its relative importance as a motivator is largely unknown. Further work is needed to explore this concept as a possible motivational tool for increasing childhood immunization uptake.

BACKGROUND. Guidelines for latent tuberculosis infection do not consider drug-resistance patterns when recommending treatment for immigrant children.OBJECTIVES. The purpose of this research was to decide at what rate of isoniazid resistance a different regimen other than isoniazid for 9 months should be considered.METHODS. We constructed a decision tree by using published data. We studied 3 regimens considered to be effective for susceptible organisms: (1) isoniazid for 9 months, (2) rifampin for 6 months, and (3) isoniazid for 9 months plus rifampin for 6 months. In addition, we evaluated a regimen of isoniazid and rifampin for 3 months. Our base case was a 2-year-old child from Russia with a tuberculin skin test reaction of 12 mm. We assumed a societal perspective and expressed results as cost and cost per case of tuberculosis prevented. We conducted sensitivity analyses to test the stability of our model.RESULTS. In our baseline analysis, rifampin was the least costly treatment regimen for any child arriving from an area with an isoniazid-resistance rate of ≥11%. Treatment with isoniazid plus rifampin was the most effective but would cost more than $1 million per reactivation case prevented. Isoniazid would become the least costly regimen if any of the following thresholds were met: rifampin resistance given isoniazid resistance of more than 82%; rifampin resistance given no isoniazid resistance of >9%; cost of rifampin more than $47/month; effectiveness of rifampin lower than 63%; effectiveness of isoniazid higher than 74%; and cost of pulmonary tuberculosis less than $7661. Isoniazid and rifampin for 3 months was the least costly for all cases from areas with isoniazid resistance of 50% for susceptible bacteria. However, this assumption remains to be proven.CONCLUSION. Because of the high prevalence of isoniazid resistance, rifampin should be considered for children with latent tuberculosis infection originating from countries with >11% isoniazid resistance.
