Statement of standard

Newborn infants with suspected early-onset infection receive prompt diagnosis and effective treatment of sepsis while avoiding overuse of antibiotics.

Rationale

The goal is to reduce morbidity and mortality from early-onset sepsis and adverse effects of overuse of antibiotics. Early diagnosis and treatment of early-onset neonatal sepsis (EONS) are critical in preventing severe and life threatening complications and mortality. Diagnosis of EONS is difficult due to the often subtle, nonspecific clinical presentation and low predictive values of biomarkers. (1–4) Uncertainty about the presence of neonatal infection may result in unnecessary and prolonged antibiotic treatment. (5,6) A population-based study in Norway reported a rate of 2.3% of all term infants started on antibiotic therapy due to suspected EONS, whereas the incidence of culture-proven EONS was 0.05%. (7) In other European countries and the United States of America even higher proportions of all term infants are started on antibiotic therapy. (8,9)

Antibiotics may have several effects: life-saving for the individual with a severe infection; beneficial for the community hindering spreads of bacteria; problematic for the community regarding development of resistance and for the individual via collateral damage of the microbiome. (10) In early life, antibiotic mediated alteration of the microbiome may have potential consequences for future health. (11–13) In addition, prolonged duration of antibiotic exposure in preterm infants is associated with higher mortality and morbidity, such as chronic lung disease, retinopathy of prematurity, periventricular leucomalacia, and necrotising enterocolitis. (14) Therefore, reduction of unnecessary or prolonged antibiotic therapy is one of the key steps of antimicrobial stewardship to improve future health of the individual and to impede the emergence of multidrug resistant bacteria. (11–16)

Benefits

Short-term benefits

  • Reduced mortality (17–20) and morbidity (21,22)
  • Reduced unnecessary and prolonged antibiotic therapy for suspected infection (7–9)

Long-term benefits

  • Reduced development of multidrug resistance (MDR) (15)
  • Reduced alteration of the infant microbiome, with implication for later health (10–13)

  • Ensure facilities for rapid detection of bloodstream infection.
  • Start with an antibiotic stewardship programme.

  • Develop and implement a national guideline on management of newborn infants with suspected EONS in conjunction with obstetric guidance on intrapartum prophylaxis.

Description

Different national guidelines for the management of suspected EONS are published in Europe and may serve as examples: Guidelines from the United Kingdom (NICE) (17), from Belgium (24), and Switzerland (26). These guidelines are not uniform and differ in some points. (27) The diversity of the guidelines reflects the diversity of their national healthcare system. It is also a consequence of a different translation of available data to clinical practice such as the approach of maternal risk factors for EONS. Guidelines for the management of EONS have to be adapted to the specific healthcare practices such as screening for maternal colonisation with Group B streptococci, and possibilities for observation of newborns at increased risk for EONS.
