Abstract
During the year 1983, NM data were collected prospectively on all liveborn infants with a GA of <32 weeks(wks) and/or a BW of <1500 gr, admitted to 102 neonatal wards(level 1,2 and 3 hospitals) in the Netherlands. The 1208 infants, admitted to the study (133 infants excluded because of lethal congenital malformations or uncertain GA) represent 94% of the total liveborn population of this category in the Netherlands. Results were:
By fitting these data to a loglinear model (figure) we were able to demonstrate that GA has a significantly larger influence on NM than BW. We conclude that GA rather than BW should be used in NM statistics of premature infants.
