Preterm prelabor rupture of membranes: evaluating latency and neonatal morbidity for pregnancies with expectant management ≥34 weeks.

Objective: To evaluate the association between latency and neonatal morbidity for pregnancies with expectant management of PPROM ≥34 w.Materials and Methods: A retrospective cohort of singletons with PPROM from 2011 to 2016. Exposure was defined as latency (period from diagnosis of PPROM to delivery) and was analyzed as a count variable (i.e. number of days) and binary variable (≥7 days and 72 h. Fisher's exact test, chi-square test, Mann-Whitney U and binary logistic regression tests were performed with p 21 days should be an area of future investigation and may suggest there is a population of pregnancies with PPROM which may not benefit from expectant management past 34 weeks.
