Abstract:
Data on infection in a neonatal unit were collected prospectively for seven years. After the first four years, the number of surface cultures obtained from neonates with suspected sepsis and for surveillance was reduced. Rates of systemic infection (sepsis and meningitis) were not significantly different in the four years before and the three years after this change. Reduction in surface culture information made no observable difference to detection of colonisation in neonates with early onset sepsis (within first 48 hours of life) nor to antibiotic choice in late onset sepsis. Decisions concerning the length of antibiotic course in suspected infection were not adversely affected. Reduction in the number of surface cultures led to considerable saving of time, effort, and cost while appearing safe in terms of clinical practice and outcome.
Insights
Reducing surface cultures in neonatal units did not impact infection detection or treatment. This change saved resources without affecting clinical outcomes or patient safety in neonatal sepsis care.
Area of Science:
- Neonatal Medicine
- Infectious Diseases
- Clinical Microbiology
Background:
- Neonatal units require vigilant infection surveillance.
- Surface cultures are a common diagnostic tool for neonatal infections.
Purpose of the Study:
- To evaluate the impact of reducing surface cultures on neonatal infection rates.
- To assess the safety and efficacy of decreased surface culture use in neonatal care.
Main Methods:
- Prospective data collection over seven years in a neonatal unit.
- Comparison of infection rates and clinical decisions before and after reducing surface cultures.
Main Results:
- No significant difference in systemic infection rates (sepsis, meningitis) after reducing surface cultures.
- No observable impact on early-onset sepsis colonization detection or antibiotic choice for late-onset sepsis.
- Clinical decisions on antibiotic duration remained unaffected.
Conclusions:
- Reducing surface cultures in neonatal units is safe and cost-effective.
- This practice change conserves resources without compromising patient outcomes or clinical management.
