Distilling the Key Elements of Pediatric Appendicitis Clinical Practice Guidelines

Use of clinical practice guidelines (CPGs) have been shown to reduce care delays, optimize resource utilization, and improve patient outcomes. We conducted a systematized review to identify key elements that should be included in an evidence-based CPG for pediatric appendicitis.

We characterized key decision points and content areas from CPGs developed from 2000 to 2019 that were identified using publicly available platforms and manual search/personal communications.

Twenty-seven CPGs were reviewed with content saturation achieved after reviewing eight. We found 16 key elements spanning from triage to postoperative care. Elements with high accord among CPGs included use of laparoscopy and delay of postoperative imaging for abscess screening until postoperative day seven. For simple appendicitis, all CPGs endorsed antibiotic cessation, diet advancement, and early activity, and 11 CPGs included same-day discharge. Elements with heterogeneity in decision-making included antibiotic selection/duration for perforated appendicitis, criteria defining perforation, and utility of postoperative laboratory evaluations.

Development of an evidence-based CPGs for pediatric appendicitis requires attention to a finite number of key decision points and content areas. Existing literature demonstrates improved patient outcomes with CPG implementation.
