Figure 51. Survival rate in preterm 28-31 weeks gestational age according to centres
3.10.2.2 Survival rate of babies of birth weight between 501-1000 g and 22-27 weeks gestational age
The survival rate of babies between 501-1000 g birth weight showed a wider variation from 29-73 Table 52. The study group included the group of preterm babies who died shortly after delivery and
were never admitted into the NICU and this should be taken into account. Reasons given earlier for the larger VLBW babies may also apply for the variation in survival rate in this group of babies. In
addition, the individual NICU policy regarding aggressive or conservative management in these babies may have affected the final outcome. Figure 52 shows the relative distribution of babies in
this birth weight category and the number of survivors.

mortality rates are calculated pertaining to that for inborn babies only. Perinatal mortality rate
