Abstract

<p><strong>BACKGROUND: </strong>Studies estimate that 30-50% of antibiotics prescribed for hospitalized patients are inappropriate, but pediatric data are limited. Characterization of inappropriate prescribing practices for children are needed to guide pediatric antimicrobial stewardship.</p>

<p><strong>METHODS: </strong>Cross-sectional analysis of antibiotic prescribing at 32 US children's hospitals. Subjects included hospitalized children with ≥1 antibiotic order at 0800 on one day per calendar quarter, over six quarters (Quarter 3 2016 - Quarter 4 2017). Antimicrobial stewardship program (ASP) physicians and/or pharmacists used a standardized survey to collect data on antibiotic orders and evaluate appropriateness. The primary outcome was the percentage of antibiotics prescribed for infectious use that were classified as suboptimal, defined as inappropriate or needing modification.</p>

<p><strong>RESULTS: </strong>Of 34 927 children hospitalized on survey days, 12 213 (35.0%) had ≥1 active antibiotic order. Among 11 784 patients receiving antibiotics for infectious use, 25.9% were prescribed ≥1 suboptimal antibiotic. Of the 17 110 antibiotic orders prescribed for infectious use, 21.0% were considered suboptimal. Most common reasons for inappropriate use were bug-drug mismatch (27.7%), surgical prophylaxis &gt;24 hours (17.7%), overly broad empiric therapy (11.2%), and unnecessary treatment (11.0%). The majority of recommended modifications were to stop (44.7%) or narrow (19.7%) the drug. ASPs would not have routinely reviewed 46.1% of suboptimal orders.</p>

<p><strong>CONCLUSIONS: </strong>Across 32 children's hospitals, approximately 1 in 3 hospitalized children are receiving one or more antibiotics at any given time. One quarter of these children are receiving suboptimal therapy, and nearly half of suboptimal use is not captured by current ASP practices.</p>

Abstract

<p>In this multicenter study, we identified an increased risk of 30-day mortality among hospitalized children with carbapenem-resistant Enterobacteriaceae (CRE) isolated from clinical cultures compared with those with carbapenem-susceptible Enterobacteriaceae. We additionally report significant variation in antibiotic treatment for children with CRE infections with infrequent use of combination therapy.</p>

Abstract

<p>Carbapenem-resistant Enterobacteriaceae (CRE) are increasingly identified in children in the United States, but data on the epidemiology of CRE in this population are limited. The objectives of this study were to characterize risk factors for colonization or infection with CRE and describe the microbiologic characteristics of pediatric CRE isolates. We performed a multicenter matched case-control study from January 2011 to October 2015 at three tertiary care pediatric centers. Case patients were hospitalized children with CRE isolated from clinical cultures and were matched in a 2:1 ratio to control patients with carbapenem-susceptible Enterobacteriaceae (CSE). Risk factors for colonization or infection with CRE were then evaluated using multivariable conditional logistic regression. Additionally, we comprehensively reported the antimicrobial susceptibility pattern for CRE isolates. Sixty-three case patients were identified and matched to 126 control patients. On multivariable analysis, anti-pseudomonal antibiotic exposure within the previous 3 months (odds ratio [OR], 5.20; 95% confidence interval [CI], 1.71-15.9, P=0.004), prior surgery (OR, 6.30; 95% CI, 1.83-21.6, P=0.003), and mechanical ventilation (OR, 12.4; 95% CI, 1.26-122, P=0.031) were identified as risk factors for colonization or infection with CRE. Pediatric CRE isolates demonstrated relatively low rates of resistance to amikacin (5%) and ciprofloxacin (25%). Our findings support an important role for antibiotic stewardship interventions limiting the unnecessary use of anti-pseudomonal antibiotics as a strategy to prevent widespread emergence of CRE in children. Future studies should further characterize molecular determinants of antibiotic resistance among pediatric CRE isolates.</p>
