Pediatric Antibiotic Stewardship.

Abstract

ABSTRACT\nWith the rise of antibiotic resistance, antimicrobial stewardship programs can now be found in the ambulatory setting, where nearly 95% of antibiotic prescriptions originate. Judicious use of antibiotics is of particular importance to the ambulatory pediatric provider, as the annual antibiotic prescription rate is highest among children ages two and younger and inappropriate early-life antibiotic use is associated with elevated childhood risk of several medical conditions. While most ambulatory antibiotic stewardship programs have focused on shaping clinician behaviors to prevent unnecessary antibiotic prescribing, duration of antibiotic therapy has been found to be a critical, yet underexamined, facet of antibiotic use. In the past, duration of antibiotic therapy was largely based on convention and expert opinion, with little scientific evidence supporting many of the recommendations. Research suggests that many common pediatric infections such as acute otitis media, community-acquired pneumonia, streptococcal pharyngitis, and urinary tract infections can be effectively and safely treated with reduced courses of antibiotic therapy. In addition to reducing the incidence of antibiotic resistance, a shorter duration of antibiotic therapy may help prevent many adverse effects associated with antibiotic treatment. Current studies on the duration of antibiotic therapy, especially in pediatrics, are limited as they often rely on data extrapolated from adult studies that fail to consider the effects of age-related growth and development on both pharmacokinetics and pharmacodynamics. Future investigation into this topic is also limited by researchers reliance on subsidies from pharmaceutical companies; clinicians fear of undertreating infection; and hesitancy to deviate from current standards of care, even when such standards are not evidence based. Despite these challenges, the dangers of inappropriate antibiotic use in the pediatric population warrant further evaluation.
