Conditions

Preterm Birth, Preterm Labor, Intra-amniotic Infection, Amniocentesis Affecting Fetus or Newborn

Brief summary

Implementation of prediction models of risk of spontaneous delivery within 7 days or of intra-amniotic infection in women with preterm labor and intact membranes

Detailed description

To evaluate whether the implementation of prediction models of risk of spontaneous delivery within 7 days or of intra-amniotic infection: 1. Optimises antenatal management (regarding steroids, tocolysis, antibiotics, maternal length stay duration) without worsening perinatal outcomes. 2. It is a cost-effective strategy. 3. It improves neonatal outcome (in premature newborns \<30 weeks), and reduces infectious maternal morbility. 4. It improves neurodevelopmental outcome at 1.2 and 5 years.

Interventions

Steroids doses will be optimized in the intervention group according the risk based on predictive models

Tocolysis duration will be optimized in the intervention group according the risk based on predictive models
