Variability in antibiotic use at children's hospitals

Area of Science:

• Pediatric Healthcare
• Infectious Disease Management
• Clinical Quality Improvement

Background:

• Significant variation exists in medical practices, highlighting potential areas for patient care enhancement.
• The extent of variation in antibiotic prescribing patterns within pediatric hospitals remains largely uncharacterized.

Purpose of the Study:

• To investigate the degree of variation in antibiotic utilization across children's hospitals.
• To identify factors contributing to antibiotic use disparities in pediatric inpatient settings.

Main Methods:

• A retrospective cohort study analyzed data from 556,692 pediatric inpatient discharges across 40 children's hospitals between 2008 and 2008.
• The Pediatric Health Information System (PHIS) was utilized to extract comprehensive data on antibiotic administration and patient diagnoses.

Main Results:

• Overall, 60% of pediatric patients received at least one antibiotic during hospitalization.
• Substantial inter-hospital variation in antibiotic exposure (38%-72%) and duration (368-601 antibiotic-days per 1000 patient-days) was observed, even after adjusting for patient and hospital characteristics.
• Hospitals with higher overall antibiotic use also tended to prescribe a greater proportion of broad-spectrum antibiotics.

Conclusions:

• Children's hospitals exhibit considerable unexplained variation in antibiotic prescribing practices.
• This variability presents a significant opportunity for optimizing antibiotic stewardship and improving patient outcomes in pediatric care.
