Improvements in Antimicrobial Prescribing and Outcomes in Pediatric Complicated Appendicitis

Area of Science:

• Pediatric surgery
• Infectious diseases
• Antimicrobial stewardship

Background:

• Complicated appendicitis in children often leads to frequent late infectious complications.
• Current antibiotic treatment strategies lack standardization, causing significant variations in patient care.
• Optimizing antibiotic use is crucial for managing pediatric complicated appendicitis.

Purpose of the Study:

• To evaluate the impact of an antimicrobial stewardship program (ASP) and a clinical practice guideline (CPG) on antibiotic utilization.
• To assess the effect of these interventions on patient outcomes in children with complicated appendicitis.
• To determine if a standardized approach improves care for pediatric complicated appendicitis.

Main Methods:

• A retrospective review of 313 children with complicated appendicitis managed with early appendectomy was conducted.
• Patients were categorized into three groups based on exposure to: neither intervention, ASP only, or both ASP and CPG.
• Antibiotic utilization metrics and clinical outcomes were compared across the three study eras.

Main Results:

• Antimicrobial stewardship program (ASP) implementation reduced the use of broad-spectrum or toxic antibiotic regimens.
• Clinical practice guideline (CPG) implementation led to decreased overall antibiotic use and fewer discharges with intravenous antibiotics.
• Combined ASP and CPG exposure resulted in a reduction in surgical-site infections, with over 90% compliance with CPG recommendations.

Conclusions:

• Complicated appendicitis management is a key area for antimicrobial stewardship and quality improvement initiatives.
• A condition-specific clinical practice guideline (CPG) effectively enhances both antimicrobial utilization and patient outcomes.
• Integrated stewardship and guideline-based care represent a valuable strategy for improving pediatric appendicitis treatment.
