Neonatal Outcome by Reason for Delivery

Obstetrix Medical Group995 enrolled

Overview

To determine the rate of Composite Neonatal Morbidity for very preterm babies delivered secondary to preterm labor (PTL) vs. prelabor rupture of membranes (PROM). Composite neonatal morbidity is defined as ≥ 1 of the following: Respiratory Distress Syndrome (RDS) (oxygen requirement, clinical diagnosis, and consistent chest radiograph), bronchopulmonary dysplasia (BPD) (requirement for oxygen support at 28 days of life), severe intraventricular hemorrhage (IVH) (grades III or IV), periventricular leukomalacia (PVL), blood culture-proven sepsis, necrotizing enterocolitis (NEC), or perinatal death (stillbirth or death before neonatal hospital discharge.

This is a prospective, observational study that will use information from the medical records of mothers and their newborns. This study seeks to determine the rate of Composite Neonatal Morbidity for very preterm babies delivered secondary to preterm labor (PTL) vs. prelabor rupture of membranes (PROM). Composite neonatal morbidity is defined as ≥ 1 of the following: Respiratory Distress Syndrome (RDS) (oxygen requirement, clinical diagnosis, and consistent chest radiograph), bronchopulmonary dysplasia (BPD) (requirement for oxygen support at 28 days of life), severe intraventricular hemorrhage (IVH) (grades III or IV), periventricular leukomalacia (PVL), blood culture-proven sepsis, necrotizing enterocolitis (NEC), or perinatal death (stillbirth or death before neonatal hospital discharge. Secondary Objectives: 1) Difference in mortality between the PTL and PROM groups, composite morbidity differences for other reasons for premature delivery, and individual morbidities including IVH, PVL, RDS, sepsis, seizures, BPD and NEC Study Population: All babies from singleton pregnancies delivering in each of the involved hospitals who deliver at less than 32 weeks of gestation who are stillborn, who die in the delivery room and who are cared for in the Neonatal Intensive Care Unit (NICU) will be included. Planned Sample Size: We plan a two year study and estimate based on historical data for the institutions to be included in the study, which should yield approximately 6000 babies less than (\<) 32w0d gestation. For a 10% difference in composite morbidity (assuming 90% power and two-sided alpha=0.05) assuming a rate of 60% at least 661 patients are needed in each of the 3 groups (PTL, PROM, and other).

Outcomes

Primary Outcomes

Composite Perinatal Morbidity

The primary outcome is Composite Perinatal Morbidity. Composite morbidity refers to the newborns born to the female participants enrolled in the study. Composite Morbidity is defined as ≥ 1 of the following: respiratory distress syndrome (RDS) (oxygen requirement, clinical diagnosis, and consistent chest radiograph), bronchopulmonary dysplasia (BPD) (requirement for oxygen support at 28 days of life), severe intraventricular hemorrhage (IVH) (grades III or IV), periventricular leukomalacia (PVL), blood culture-proven sepsis present within 72 hours of birth, necrotising enterocolitis (NEC), or perinatal death (stillbirth or neonatal death prior to hospital discharge).

Time frame: Infants from birth until discharge or until infant reaches 28 days of life.
