Insights
Reducing antibiotic duration for early-onset neonatal infection (EONI) is safe and effective. This approach lowers the risk of late-onset infections without increasing relapse rates in newborns.
Area of Science:
- Neonatal Medicine
- Infectious Diseases
- Pharmacology
Background:
- Broad-spectrum antibiotic use in neonatal infections has altered pathogen profiles and resistance patterns.
- Restrictive guidelines for antibiotic therapy in neonates have been developed to promote rational use.
- This study assessed the effectiveness and compliance of these new guidelines for early-onset neonatal infection (EONI).
Purpose of the Study:
- To evaluate the impact of restrictive antibiotic guidelines on EONI treatment.
- To assess compliance with guidelines limiting broad-spectrum antibiotic use and treatment duration.
- To determine the effectiveness of shortened antibiotic therapy in preventing infectious relapse and late-onset infections.
Main Methods:
- Population-based observational study in 18 Burgundy hospitals (February 2002 - June 2003).
- Prospective surveillance of neonates receiving antibiotics within 72 hours of life.
- Evaluation of outcomes for 60 days post-birth, defining unfavorable outcomes as death or late-onset infection.
Main Results:
- Out of 25,480 infants, 1012 received antibiotics at birth; 39 were septicemic, 288 clinically infected, 685 not infected.
- The EONI cure rate was 96.8% with no infectious relapses.
- Factors associated with late-onset infection included low birth weight, mechanical ventilation, central venous catheterization, and longer antibiotic duration.
Conclusions:
- Shortening antibiotic therapy duration for EONI does not elevate the risk of infectious relapse.
- Reducing antibiotic treatment duration may decrease the incidence of late-onset infections in neonates.
Background:
The extensive use of broad-spectrum antibiotics has been associated with major changes in the spectrum of organisms involved in early-onset neonatal infection (EONI), their susceptibility to antibiotics, or both. Therefore, guidelines for a more rational use of antibiotics in neonates have been developed. We conducted a population-based observational study to assess the effectiveness and compliance with restrictive guidelines for the antibiotic therapy in EONI.
Methods:
Neonates receiving antibiotics within 72 hours of life were identified prospectively by population-based surveillance in the 18 hospitals of Burgundy, between February 2002 and June 2003. They were treated in accordance with guidelines limiting the use of broad-spectrum antibiotics and shortening the treatment duration. Each neonate included was evaluated for 60 days after birth. An unfavorable outcome was defined as death related to EONI or late-onset infection.
Results:
Of the 25,480 infants born during the study period, 1012 received antibiotics at birth. Of these 1012 infants, 39 were definitely infected (septicemia), 288 clinically infected and 685 not infected. The EONI cure rate was 96.8% without infectious relapse. Forty-five infants received a second course of antibiotic therapy. Birth weight (OR: 5.6; 95% CI: 2.2-14.1), mechanical ventilation (OR: 4.1; 95% CI: 1.3-13.1), central venous catheterization (OR: 16.1; 95% CI: 1.8-141.9), and antibiotic therapy duration (OR: 2.5; 95% CI: 1.1-5.5) were independently associated with late-onset infection.
Conclusion:
Reducing the antibiotic therapy duration does not increase the risk of infectious relapse and may decrease the incidence of late-onset infection.
