Mesvaht et al analyzed factors associated with failure of empirical antibiotic therapy in a neonate with early onset sepsis. They developed a decision tree for factors known at 24 hours after birth. The authors are from Tartu University and Tallinn Children's Hospital in Estonia.
Empirical antibiotic therapy: penicillin/ampicillin plus gentamicin
Parameters known at 24 hours after birth:
(1) blood glucose in mmol/L
(2) C-reactive protein in mg/L
(3) gestational age at birth in weeks
(4) birthweight in grams
(5) white blood cell count in 10^9/L
(6) platelet count in 10^9/L

where:
• A glucose of 2.55 mmol/L is around 46 mg/dL.
A probability of treatment failure >= 0.30 was defined as treatment failure.
