Antibiotic use Evaluation in Hospitalized Pediatric Patients with Respiratory Tract Infections: A Retrospective Chart Review Study.

INTRODUCTION

Respiratory tract infections (RTIs) are a common cause of antibiotic usage in hospitalized pediatric patients. Inappropriate use of antibiotics may lead to the emergence of multidrug-resistant microorganisms and increased treatment costs.

OBJECTIVE

This study was designed to assess antibiotic usage in hospitalized pediatric patients with RTIs.

METHODS

Medical charts of the patients admitted to the pediatric ward (PW) and pediatric intensive care unit (PICU) of a tertiary respiratory center were reviewed. Patients' demographic and clinical data, including gender, age, weight, history of allergy, length of hospital stay, clinical diagnosis, and prescribed antibiotics (indication, dose, and frequency of administration) were collected. The appropriateness of antibiotic usage was evaluated in each patient according to international guidelines.

RESULTS

Two hundred seventy-nine hospitalized patients were included in the study. The most common reason for hospitalization was pneumonia (38%), followed by cystic fibrosis (20.1%) and bronchitis (5%). The most commonly used antimicrobial agents were ceftriaxone, azithromycin, and clindamycin which guideline adherence for their usage was 85.3%, 23.3%, and 47%; respectively. Inappropriate dose selection was the main reason for non-adherence to the guidelines. The adherence rate to RTIs' guidelines (considering all parameters for each patient) was 27.6%. Multivariate logistic regression analysis demonstrated CF and prescription of azithromycin are predictors of guideline non-adherence.

CONCLUSION

We found relatively low adherence to international guidelines in our center that could be related to restricted definitions of optimal antibiotic therapy. Despite most patients received logical antimicrobial therapy, actions should be taken into account to reach optimal antibiotic usage.
