Can we back off using antibiotics in the NICU?

Area of Science:

• Neonatal Medicine
• Infectious Diseases
• Pharmacology

Background:

• Antibiotic prescribing in neonatal intensive care units (NICUs) is inconsistent and excessive, not correlating with culture-positive sepsis rates.
• Overuse of antibiotics in neonates leads to adverse short- and long-term effects, including increased multidrug-resistant organisms.
• Significant variation exists in neonatologist antibiotic prescribing practices, highlighting the need for standardization.

Purpose of the Study:

• To advocate for antibiotic stewardship in NICUs to standardize antibiotic use and improve patient outcomes.
• To evaluate current strategies for neonatal sepsis identification and their limitations in reducing antibiotic utilization.
• To propose a conservative "watch and wait" algorithm as an alternative approach to antibiotic initiation in neonates.

Main Methods:

• Review of current antibiotic prescribing practices and their correlation with sepsis rates in NICUs.
• Analysis of the adverse effects of neonatal antibiotic overuse, including the rise of multidrug-resistant organisms.
• Proposal and description of a "watch and wait" observational algorithm for initiating antibiotic therapy.

Main Results:

• Antibiotic usage in NICUs is extensive and inconsistent, with no clear link to culture-proven sepsis.
• Current sepsis identification strategies often lead to the treatment of non-septic infants.
• The proposed "watch and wait" algorithm offers a method to reduce antibiotic exposure by relying on clinical observation.

Conclusions:

• Implementing antibiotic stewardship in NICUs is essential for optimizing antibiotic use and enhancing neonatal outcomes.
• A conservative "watch and wait" strategy, supported by trained personnel, can potentially decrease unnecessary antibiotic prescriptions.
• Standardizing antibiotic prescribing through evidence-based approaches like clinical observation is crucial for combating antimicrobial resistance in neonates.
