Outcome Measures
Primary Outcomes (1)
Registry of baseline and outcome data for VLBW infants with data collected in a uniform manner
Data items include infant and maternal characteristics, delivery room interventions, respiratory care and outcomes, surgeries, infections, other serious complications, and length of stay. Time frames for data collection include: characteristics of birth; at day 28; and at discharge. Tracking ends at discharge home (including for infants transferred out) or at one year.
up to 1 year
Study Arms (1)
Very low birth weight infants
Infants \<=1500 g or \<=29 weeks gestational age admitted to Vermont Oxford Network member centers within 28 days of birth
Interventions
