Background: Uncertainty about the presence of neonatal early-onset sepsis (EOS) results in unnecessary and prolonged empiric antibiotic treatment. This study evaluates whether Procalcitonin (PCT)-guided treatment for suspected EOS can reduce the duration of antibiotic treatment with unchanged outcome (re-infection/death in the first month of life with 2% margin for non-inferiority).

Methods: Randomized controlled intervention trial recruiting neonates (gestational age ≥ 34 weeks) suspected of EOS requiring antibiotic therapy. Patients were stratified in 4 risk-categories and randomized for duration of antibiotic treatment based on PCT-guided-decision-making or standard care. Analyses were done as intention-to-treat (ITT) as well as per protocol (PP).

Results: 1710 neonates were randomized and included in the ITT analysis, 1408 in the PP analysis. The duration of antibiotic therapy was significantly shorter in the PCT-group than in the standard group (ITT: 55.1 vs. 65.0 hours, p<0.001; PP: 40.0 vs. 62.0 hours; p<0.001). Length of hospital stay was significantly (p=0.0028) reduced in the PCT group with a small effect size (ITT: -3.5 hours; PP: -5.2 hours). No sepsis related deaths occurred and the rate of possible re-infection was below 1% with a risk difference of 0.1% (exact CI -4.6 to 4.8%). Non-inferiority (margin 2%) could not be statistically proven due to the low occurrence of possible relapse infections.

Conclusion: Initial risk assessment for suspected EOS and PCT-guidance on duration of empirical antibiotic therapy results in a significant reduction of duration of antibiotic therapy and length of hospital stay. The effect size is dependent on protocol adherence. The used approach seems to be safe whereas non-inferiority cannot be claimed statistically.
