Background: Children treated for community-acquired pneumonia (CAP) with penicillin, amoxicillin, or ampicillin have outcomes similar to those treated with broad-spectrum agents, and 2011 IDSA/PIDS guidelines recommend these agents as first-line therapy for pediatric CAP. Use of recommended agents has improved in children’s hospitals following guideline release. A substantial proportion of pediatric CAP hospitalizations, however, occur in non-children’s hospitals, where post-guideline antibiotic use has not been evaluated.

Methods: Retrospective analysis of children 1-17 years admitted in 2013 to 323 hospitals, captured via the Pediatric Health Information System and Premier Perspective databases. Children’s hospitals were identified as having >75% pediatric admissions (n=49). Children with CAP were identified using a validated ICD-9 code-based algorithm, excluding those with complicated pneumonia, complex chronic conditions, receipt of intensive care, and MRSA infection or colonization. Antibiotic use was assessed as: 1) ever received penicillin, ampicillin, or amoxicillin (“guideline”), 2) ever received a macrolide, fluoroquinolone, or tetracycline (“atypical”), and 3) received any non-guideline antibiotic. Standardized probability of exposure to select antibiotics was compared between children’s and non-children’s hospitals, adjusting for age, sex, and insurance provider.

Results: Of 15,222 children hospitalized with CAP, 60% were admitted to children’s hospitals. Median age was 3 years (IQR 2-6 years); 51% were male and 56% had public insurance. After adjustment, children admitted to non-children’s hospitals received guideline therapy less often than those in children’s hospitals, and received atypical coverage and non-guideline therapy more often than those in children’s hospitals (Table, p<0.001 for all comparisons).

Conclusion: Significant disparities exist in antibiotic prescribing for pediatric CAP between children’s and non-children’s hospitals. Further study is needed to understand these differences and improve guideline adherence for all children hospitalized with CAP.
