# Adherence to Perioperative Antimicrobial Prophylaxis in Children in the Settings of Neurosurgery, Otorhinolaryngology, and Orthopedics

## TL;DR

This study examines how well doctors follow guidelines for giving antibiotics before and after surgery in children across three surgical fields, finding significant gaps in compliance.

## Contribution

The study provides new insights into antimicrobial prophylaxis adherence in pediatric neurosurgery, orthopedics, and otolaryngology.

## Key findings

- Only 0% of neurosurgery patients received guideline-adherent antimicrobial prophylaxis.
- Shorter surgeries and clean wounds in otolaryngology were linked to not using PAP.
- Most patients received broad-spectrum or prolonged antibiotic use.

## Abstract

Introduction: Data about compliance with perioperative antimicrobial prophylaxis (PAP) guidelines in the pediatric population are limited. This study aims to evaluate PAP adherence in pediatric surgical subspecialty departments. Methods: A prospective cohort study was conducted from September 2023 to October 2024 at “Aghia Sophia” Children’s Hospital, Athens, Greece. Children <16 years old undergoing surgical procedures in the neurosurgery (NS), orthopedics (OP), and otolaryngology (ORL) departments were included. Data on demographics, surgical characteristics, and PAP practices (timing, agent, duration, and redosing) were collected and compliance with the international guidelines was evaluated. Results: A total of 301 children were included, with a median age (IQR) of 7 (8) years. PAP was received by 249/301 (82.7%) children (100% in the OP and NS, and 48% in the ORL). However, indications for PAP had 50.8% of children: 102/103 (99%) in the NS, 47/98 (47.9%) in the OP, and 4/48 (8.3%) in the ORL. Most children received broad-spectrum or combination of antimicrobials and/or antibiotics for longer duration. Appropriate PAP according to the guidelines was administered in 0% children in NS, 2% in OP, and 2.1% in ORL. Multivariable analysis in the ORL regarding the use of PAP revealed that shorter procedures (≤60 min; OR: 22.9, p = 0.003) and clean wounds (OR: 33.4, p < 0.001) were significantly associated with not using PAP. Conclusions: This study highlights gaps in the PAP guideline adherence in pediatric surgical departments, and the need for educational interventions to improve compliance and reduce antimicrobial use. Based on these findings, we plan to implement an educational intervention in order to optimize PAP practices in the pediatric population.
