ABSTRACT
Background
Hospital antibiotic use is rising. We aimed to evaluate the antibiotic-use prevalence and length of stay.
Methods
We conducted a single-center retrospective study of patients < 18-years-old admitted to general pediatric services who received ≥ 1 antibiotic over six months. Demographics, culture results and antibiotic details were collected. The primary outcome was to identify the total number and classes of antibiotics prescribed during the admission. Secondary outcomes included length of stay (LOS), culture results, and the most commonly used antibiotics.
Results
Forty-eight percent of patients received monotherapy (single class antibiotic). Cephalosporins (55%), vancomycin (35%), and clindamycin (22%) were prescribed more commonly than other antibiotic classes. Children were exposed up to 4 classes of antibiotics (range 1–4). A moderate correlation existed between the length of stay and the number of antibiotic classes used (R2 = 0.38). Two or more classes of antibiotic use prolonged the length of stay. Cephalosporin use was associated with 35% reduced LOS (95 CI, 21%-57%), and penicillin use correlated with 38% more prolonged LOS (95 CI, 22%-66%).
Conclusions
Antibiotic use in pediatric hospitals was high, and children received multiple classes of antibiotics. Inappropriate antibiotic use and culture results may have an untoward effect on hospital length of stay.
Article highlights
Pediatric monotherapy prevalence is high. Most of the uncomplicated medical conditions are treated with a single antibiotic.
Polymicrobial exposure is inevitable, but actionable and can be avoided. This will reduce harm and enhance drug safety.
Antibiotic use can be associated with a prolonged hospital stay. Prolonged stay is affected by many factors, but a certain type and number of antibiotic uses can add to the problem.
Antibiotic stewardship emphasizes judicious and culture-directed antibiotic prescriptions.
Antibiotic stewardship expansion to surgical prophylaxis is in practice. Evidence-based guidelines on this topic are emerging; adhering to the best practice of antibiotic use and monotherapy is important.
