NCT05515744

Brief Summary

This study will conduct a randomized trial among women with gestational diabetes (GDM). Study of Pregnancy And Neonatal health (SPAN), TIMing of dElivery (TIME) is a randomized trial that will recruit up to 3,450 pregnant women with uncontrolled GDM and randomize the timing of their delivery. Women with GDM who are approached for the trial and are found eligible but do not consent to participating in randomization for delivery will be asked to consent for chart review only (estimated additional n=3,000). The primary objective is to determine the best time to initiate delivery for GDM-complicated deliveries (defined as the time when risk of illness and death for the newborn is the lowest) between 37-39 weeks.

Outcome Measures

Primary Outcomes (13)

  • Composite of Neonatal Morbidity and Perinatal Mortality

    Hospital discharge

  • Occurrence of Antepartum, intrapartum or neonatal death (Component of primary outcome)

    Antepartum pregnancy period through Newborn Discharge

  • Incidence of moderate or higher neonatal respiratory support within 72 hours after birth (Component of primary outcome)

    Including any of the following: Nasal cannula \>/= 2 LPM (liters per minute), Nasal continuous positive airway pressure (NCPAP), NIPPV; (non-invasive intermittent positive pressure ventilation; Note that NIPPV is more general than Bilevel positive airway pressure (BiPAP) i.e. BiPAP is a form of NIPPV, as is non-invasive NAVA, synchronized NIPPV, non-synchronized NIPPV, some ventilators can do nasal IMV in certain situations, etc.), Mechanical ventilation, High frequency ventilation, and ECMO/ECLS (extracorporeal mechanical support/extracorporeal life support)

    Delivery through Newborn Discharge

  • Occurrence of Pneumonia (Component of primary outcome)

    Confirmed by X-ray or positive blood culture

    Delivery through Newborn Discharge

  • Occurrence of Meconium aspiration syndrome (Component of primary outcome)

    Respiratory distress in an infant born through meconium-stained amniotic fluid with X-ray findings consistent with meconium aspiration syndrome, and whose symptoms could not be otherwise explained

    Delivery through Newborn Discharge

  • Occurrence of Sepsis (Component of primary outcome)

    The diagnosis of sepsis will require the presence of a clinically ill infant in whom systemic infection is suspected with a positive blood, CSF, or catheterized/suprapubic urine culture; or, in the absence of positive cultures, clinical evidence of cardiovascular collapse or an unequivocal X-ray confirming infection.

    Delivery through Newborn Discharge

  • Occurrence of Neonatal encephalopathy (Component of primary outcome)

    Defined by Shankaran et al. 2005

    Delivery through Newborn Discharge

  • Occurrence of Intracranial hemorrhage (Component of primary outcome)

    Intraventricular hemorrhage grades III and IV, subgaleal hematoma, subdural hematoma, or subarachnoid hematoma

    Delivery through Newborn Discharge

  • Occurrence of Seizures (Component of primary outcome)

    Delivery through Newborn Discharge

  • Occurrence of Birth trauma (Component of primary outcome)

    Bone fractures, brachial plexus palsy, other neurologic injury, retinal hemorrhage, or facial nerve palsy

    Delivery through Newborn Discharge

  • Occurrence of Hypotension requiring pressor support (Component of primary outcome)

    Delivery through Newborn Discharge

  • Occurrence of hypertrophic cardiomyopathy (Component of primary outcome)

    Delivery through Newborn Discharge

  • Incidence of neonatal intensive care unit (NICU) > 1 day (24 hours) stay

    NICU stay \> 1 day (24 hours)

    Delivery through Newborn Discharge

Secondary Outcomes (43)

  • Incidence of respiratory support less than moderate

    Delivery through Newborn Discharge

  • Duration of any respiratory support

    Delivery through Newborn Discharge

  • Duration of moderate respiratory support

    Delivery through Newborn Discharge

  • Occurrence of Transient tachypnea of the newborn

    Delivery through Newborn Discharge

  • Occurrence of Respiratory distress syndrome in Neonates

    Delivery through Newborn Discharge

  • +38 more secondary outcomes
