Clinical Report: Duration of Antibiotic Treatment in VLBW Infants with EOS

Overview

This study evaluates the duration of empirical antibiotic treatment in very low birth weight (VLBW) infants suspected of having early-onset sepsis (EOS) with negative blood cultures. It identifies factors contributing to prolonged antibiotic exposure, highlighting the need for improved antibiotic stewardship in this vulnerable population.

Background

Antibiotic exposure in VLBW infants is associated with adverse outcomes, including alterations in gut microbiota and increased morbidity. Understanding the duration of antibiotic treatment is crucial for optimizing care and minimizing risks associated with unnecessary antibiotic use. This study provides insights into actual treatment durations and factors influencing them, which can inform clinical practices.

Data Highlights

Key Findings

• 56.3% of VLBW infants received empirical antibiotics without proven infection.
• Median time from birth to antibiotic discontinuation was 45 hours.
• Initiation of antibiotics during weekends was associated with an additional 0.46 days of therapy.
• Antibiotic discontinuation occurred progressively earlier over the study period.
• Awareness of actual exposure times can guide antibiotic stewardship efforts.

Clinical Implications

Clinicians should be aware that VLBW infants are often exposed to antibiotics for longer than current guidelines recommend. Strategies to optimize antibiotic use, particularly for those born on weekends, are essential to minimize unnecessary exposure and its associated risks.

Conclusion

The findings underscore the importance of monitoring antibiotic exposure in VLBW infants and suggest that improvements in clinical practices are needed to align treatment durations with established guidelines.
