Overview
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.
Detailed Description
This is a randomized clinical trial under an adaptive design nested in a larger observational study, among women who are diagnosed with uncontrolled gestational diabetes mellitus (GDM). Women from multiple clinical sites around the United States will be recruited into the study (n=3,450). Women with GDM who are approached for the trial and are found eligible but do not consent to participating to randomization for delivery will be asked to consent for chart review only (estimated additional n=3,000). The primary objective is to determine the optimal time to initiate delivery for GDM complicated deliveries (defined as the time when neonatal morbidity and perinatal mortality risk is the lowest) between 37-39 weeks (n=3,450 women). Newborn developmental and behavior outcomes, and anthropometric measures will also be assessed as secondary outcomes, as well as an exploratory analysis to investigate whether there are clinical, non-clinical or biochemical factors such as glucose measures that will further assist in refining the interval for optimizing time of GDM complicated deliveries relative to neonatal morbidity and perinatal mortality.

Outcomes
Primary Outcomes
Composite of Neonatal Morbidity and Perinatal Mortality
Time Frame: Hospital discharge
Occurrence of Antepartum, intrapartum or neonatal death (Component of primary outcome)
Time Frame: Antepartum pregnancy period through Newborn Discharge
Occurrence of Sepsis (Component of primary outcome)
Time Frame: Delivery through Newborn Discharge
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.
Occurrence of Hypotension requiring pressor support (Component of primary outcome)
Time Frame: Delivery through Newborn Discharge
Occurrence of Meconium aspiration syndrome (Component of primary outcome)
Time Frame: Delivery through Newborn Discharge
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
Occurrence of Pneumonia (Component of primary outcome)
Time Frame: Delivery through Newborn Discharge
Confirmed by X-ray or positive blood culture
Occurrence of hypertrophic cardiomyopathy (Component of primary outcome)
Time Frame: Delivery through Newborn Discharge
Occurrence of Birth trauma (Component of primary outcome)
Time Frame: Delivery through Newborn Discharge
Bone fractures, brachial plexus palsy, other neurologic injury, retinal hemorrhage, or facial nerve palsy
Incidence of moderate or higher neonatal respiratory support within 72 hours after birth (Component of primary outcome)
Time Frame: Delivery through Newborn Discharge
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)
Occurrence of Neonatal encephalopathy (Component of primary outcome)
Time Frame: Delivery through Newborn Discharge
Defined by Shankaran et al. 2005
Occurrence of Intracranial hemorrhage (Component of primary outcome)
Time Frame: Delivery through Newborn Discharge
Intraventricular hemorrhage grades III and IV, subgaleal hematoma, subdural hematoma, or subarachnoid hematoma
Occurrence of Seizures (Component of primary outcome)
Time Frame: Delivery through Newborn Discharge
Incidence of neonatal intensive care unit (NICU) > 1 day (24 hours) stay
Time Frame: Delivery through Newborn Discharge
NICU stay \> 1 day (24 hours)
