Neonatal mortality of all patients <37 weeks gestation transported to The Children's Hospital Denver tertiary care nursery was reviewed for the years 1978-82. There were 1,972 patients of < 37 weeks gestation and 280 neonatal deaths (mortality 14.2%).
A neonatal mortality risk chart was prepared in a manner similar to that recently published by the University of Colorado.
Improved mortality for the extremely low birthweight category in the outborn population probably reflects transport of only the most vigorous infants. For the larger outborn premature infants, the increased mortality probably reflects the severity of illness of these babies and the greater number of well infants in the inborn population. We feel that the survival in our outborn population is comparable. This is significant considering the long distance many of our infants are transported.
This mortality risk chart for sick premature infants may be helpful to referring physicians and to families of these transported infants.
