The optimality concept and its clinical value.
To verify the clinical usefulness of the optimality concept in general and its prognostic value for later outcome, all babies born at all 14 maternity hospitals in Slovenia in the period from 1987 to 1991 (124,759 newborns) have been screened. In order to get an estimate of their condition Prechtl's original list of optimality has been adapted to 51 items representing mostly obstetric variables. The median of perinatal optimality scores for all newborns was 45 (six negative points) in mature, and 41 (10 negative points) in premature infants. Girls born at term scored better than mature boys, whereas there was no sex difference in the median score in prematures. Analysis of the data has shown that the majority of items which were non-optimal and which were associated with the greatest number of other non-optimal factors had to do with disturbances in oxygen supply. Children who developed cerebral palsy had a lower optimality score at birth than the remainder of the newborns. In these children the difference between the sexes is even more pronounced, to the advantage of the girls. Prematurely born children with spastic diplegia had a lower optimality score than mature children with diplegia. The opposite was noticed in children born prematurely and at term who developed spastic tetraparesis or dyskinesia. The present follow-up study has shown that predictions of disability were most accurate in the group of newborns who were clinically at risk at birth and who also had a low optimality score. The combination of both appraisals is the best way to identify newborns who need special attention.
