[Increase in perinatal referral to regional centers of premature birth in The Netherlands: comparison 1983 and 1993].
OBJECTIVE
To determine changes in referral of preterm newborns.


METHODS
Descriptive.


METHODS
Foundation for Perinatal Epidemiology the Netherlands, Leiden.


METHODS
Data regarding hospital of birth, referral, need of intensive care and mortality of the infants < 32 weeks and (or) < 1500 g birth weight born in 1993 from the National Neonatology Register were supplemented with data from a questionnaire for hospitals not included in the register. The data were compared with those of similar infants from the 'Project on preterm and small for gestational age', born in 1983.


RESULTS
In 1983, 61% of the preterm infants were treated in a perinatal centre: 39% were not referred. In 1993 these numbers were 89% and 11%, respectively. The contribution of antenatal referral increased from 29% to 47% while that of postnatal referral decreased from 41% to 25%. Mortality decreased from 25.4% in 1983 to 14.3% in 1993.


CONCLUSIONS
Regionalization of high risk perinatal care resulted in concentration of care for preterm infants. At the same time, in-hospital mortality decreased by almost 50%.
