Insights

Hospital size and patient registration history influence antimicrobial changes in pediatric acute otitis media (AOM). Antimicrobial stewardship programs are key to promoting appropriate AOM treatment.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Pharmacology

Background:

  • Appropriate antimicrobial use is crucial for managing pediatric acute otitis media (AOM).
  • Understanding factors influencing antimicrobial treatment changes is essential for optimizing AOM care.

Purpose of the Study:

  • To investigate factors affecting changes in first-line antimicrobial agents for pediatric AOM.
  • To promote the appropriate use of antimicrobials in AOM treatment.

Main Methods:

  • Descriptive study utilizing an electronic medical records database.
  • Analysis of 16,353 pediatric AOM patients (1996-2019) using classification and regression trees (CART).
  • Factors influencing antimicrobial agent changes within 14 days were analyzed.

Main Results:

  • Facility size (number of beds) and historical patient registration duration impacted antimicrobial changes.
  • 4,860 cases of AOM alone and 9,567 cases of AOM with comorbidities were analyzed.

Conclusions:

  • Hospital-wide or nation-wide antimicrobial stewardship promotion significantly influences antimicrobial changes.
  • Accurate diagnosis and clear definitions of treatment failure are vital for AOM cases with comorbidities.
  • This study provides insights to enhance appropriate antimicrobial utilization in AOM management.
