Irish neonatal mortality--12 years on.
All Paediatricians in Ireland were requested to fill a questionnaire which dealt with data pertaining to all live-born infants over 500 g birth weight who died within the first 28 days of life in 1999. Deaths were categorized according to Wigglesworth Classification into Lethal Malformation, Immaturity (Prematurity), Asphyxia and "Specific". Each hospital and patient was assigned a unique ID number. Data from questionnaires was entered into a database. Results were compared with those previously published by Counahan and Clarke for 1987. Twenty one of the 23 paediatric centres in Ireland replied giving a response rate of 91%. The over-all number of neonatal deaths for 1999 was 186 compared to 310 for 1987. One hundred and two (55%) were < 1500 grams and 61 (33%) < 1000 g. The principal causes of death for 1999 were Congenital Malformations 39%, (n=72), Prematurity 37% (n=69) and Asphyxia 3% (n=5). This compares to figures of 39%, 40% and 8%, respectively for 1987. The overall Neonatal Mortality Rate for 1999 was 3.48/1000 with a Corrected Neonatal Mortality Rate of 2.1/1000. The Neonatal Mortality Rate and Corrected Neonatal Mortality Rate for 1987 were 5.3/1000 and 3.3/1000 respectively. The decrease in Neonatal Mortality in the past 12 years in Ireland is to be applauded. However it can lead to a false sense of security regarding standards of neonatal care. While the death of Extremely Low-Birth-Weight infants can now often be prevented, in many cases it is merely deferred to the post-neonatal period. Furthermore, no national data is available on the long term outcome and neurodevelopmental status of preterm or asphyxiated infants who survive. The possibility of establishing an Irish Neonatal Morbidity Register, aimed at improving the effectiveness and efficiency of medical care for newborn infants, must now be explored.
