This interactive calculator produces the probability of early-onset infection per 1000 babies by entering values for each maternal risk factor.
This calculator is based on the predictive model described in Karen M. Puopolo, MD, PhD, David Draper, PhD, Soora Wi, MPH, Thomas B. Newman, MD, MPH, John Zupancic, ScD, MD, Elice Lieberman, DrPH, MD, Myesha Smith, BS, and Gabriel J. Escobar, MD, "Estimating the Probability of Neonatal Early-Onset Infection on the Basis of Maternal Risk Factors" in the journal Pediatrics 2011;128:e1155-e1163."
