Abstract


In recent years a number of neonatal risk scores have been developed in order to assure a more accurate evaluation of results obtained by different NICU's. It is noteworthy that throughout the years an effort has been made to adapt the scores to the specific neonatal problems and to make them easier to use. We felt that it would be important to compare various scores (CRIB, SNAP, SNAP-PE, NTISS) in a population of premature infants. This was the main objective in this study. Between January 1992 and February 1995 a total of 186 infants with birthweight under 1500 grams and/or gestational age under 32 weeks were admitted to our Unit. There were 40 deaths (21.5%). It was possible to use the four above mentioned scores retrospectively. The area under the ROC curve (for predicting in-hospital mortality) in each score was: CRIB 0.90; SNAP 0.88; SNAP-PE 0.88; NTISS 0.85. The CRIB score was easier to perform (only 5 minutes, in contrast to 20-30 minutes for the other scores). From this study CRIB score is apparently a suitable and accurate method easily performed in clinical practice.
