Outcome Measures

Primary Outcome Measures :
  1. 1. Composite Outcome of Necrotizing Enterocolitis, Intraventricular Hemorrhage, Bronchopulmonary Dysplasia and Retinopathy of Prematurity at 30 and 90-days. 2. Mortality [ Time Frame: 2 weeks, 4 weeks, 12 weeks, 90 days ]
    The primary outcome was a composite outcome composed of mortality and major neonatal morbidities associated with acute organ dysfunction or failure. In addition to death, the 4 major morbidities comprising the composite outcome were bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, and intraventricular hemorrhage.

Secondary Outcome Measures :
  1. Clinically Suspected Infection and Culturally Confirmed Infections [ Time Frame: 90 days ]
    Infection was categorized as clinically suspected and positive cultures.

  2. Length of Stay [ Time Frame: until last participants left neonatal intensive care unit ]
    Length of Stay in neonatal intensive unit

  3. Number of Participants Using Mechanical Ventilation. [ Time Frame: whether a mechanical ventilation was used at any time point during 90 days ]
    Number of Participants using Mechanical Ventilation
