The objective of this study was to assess the consumption of antibiotics in children using the «AWaRe» classification of antibiotics (WHO, 2017) and metrics such as days of therapy (DoT) and length of therapy (LoT) per 1000 patientdays (PD). Antibiotics were administrated to 91.1% of inpatients in 2019 and 68.2% in 2021 (p<0.05). The main reason for antibiotic prescription was acute bronchitis in both study periods. Total DoT/1000 PD increased from 717.0 in 2019 to 760.0 in 2021 (p<0.05), and total LoT/1000 PD from 679.0 to 717.4 (p<0.05). Administration of antibiotics from the Access group decreased from 2.1% in 2019 to 1.8% in 2021 (p>0.05), antibiotics from the Watch group increased from 90.7% to 97.3% (p>0.05). Although a statistically significant reduction in the antimicrobial prescription rate, we found a considerable increase in (1) prescription antibiotics with a high risk of antimicrobial resistance, and (2) the main units of antimicrobial consumption.
