• | Introduction of a mandatory national surveillance system is associated with decrease in antibacterial use on NICU. |
• | The use of penicillins with extended spectrum, aminoglycosides, glycopeptides and third-generation cephalosporins decreased over time. |
• | Use of macrolides and penicillins combined with beta-lactamase inhibitors increased over time. |
Summary |
Objectives |
To determine the influence of a national surveillance system for neonates (NEO-KISS) in neonatal intensive care units (NICUs) on consumption of antibacterial and to identify risk factors for prescriptions.
Methods |
Data on antibacterial use between 2013 and 2019 from 231 NICUs in Germany was analyzed in this longitudinal study after introduction of a mandatory module for surveillance of antibacterial consumption in preterm infants. 59,411 newborns with a birth weight under 1500 gs were under surveillance in NEO-KISS during the study period. We report the development of antibacterial consumption during the days of treatment (DOT)/1000 patient days (PD) including the name of the substance administered. Risk factors for antibacterial treatment over time were analyzed.
Results |
A total, 2,090,341 surveillance patient days were monitored. Antibacterial consumption was 430.4 DOT/1000PD (Median 380.3; IQR: 284.2–502.7). Antibacterial use significantly decreased by 19.5% from 2013, 474.3 DOT/1000PD to 382.1 DOT/1000PD in 2019. Use of penicillins with extended spectrum (J01CA), other aminoglycosides (J01GB), glycopeptide antibacterials (J01XA and J01DH), and third-generation cephalosporins (J01DD) decreased, while use of macrolides (J01FA) and combinations of penicillins, including beta-lactamase inhibitors (J01CR), increased over time. Regression analysis identified year of birth as an independent protective factor for the prescription of antibacterials in general.
Conclusion |
The implementation of a national mandatory surveillance system was associated with a reduction in antibacterial consumption in preterm infants with VLBW. Surveillance of antibacterial use is an integral part of targeting antimicrobial stewardship efforts.
