Sir,Many attempts have been made to predict the outcomeof high-risk infants as neonatal risk determination is acomplex question. These models often focus onphysiological variables during the first hours or daysof life, but also on neurological imaging or the presenceof complications (1). The outcome measures also differbut what is of greatest interest is neurological dysfunc-tion later in life. Other adverse outcomes, e.g. infections(2, 3), delayed first stool (4) or affected thyroid function(5), have also been studied.
In most cases the measure and the outcome reflect thesame underlying problem: extreme prematurity. Thereis, for instance, an increased incidence of an adverseneurodevelopmental or sensory outcome with increasedseverity of chronic lung disease (6). This kind ofinstrument will, of course, be a good determinant oflater outcome, but what would be even more valuablewould be to find an easy-to-use instrument based ondata close in time to admission that could predictneurological outcome at school-age or later. Asneonatal illness and neonatal care are complex situa-tions, a considerable amount of research effort is neededto find such a system. We welcome the initiative ofSamson and de Groot (7) and of others in striving tosearch for this system.

Predictors of outcome. Comment on the article by Eriksson et al. (1)
Sir,All the indices used in the study by Eriksson et al. (1)were better predictors of early outcome than outcome at4 y of age in newborns with birthweights (BW) below1500 g. We studied the prediction of minor neurologicaldysfunction (MND, examination of Touwen, (2)) at 7 yin children born as high-risk preterm infants (gestationalage (GA) 32 wk and/or BW 1500 g and NeonatalMedical Index III (NMI) of Korner et al. (3, 4)).Perinatal factors such as GA, BW, small for GA, dayson the ventilator and/or days on continuous positiveairway pressure, brain ultrasound classification andNMI were used to predict outcome at 7 y in thesechildren. We were able to predict MND at 7 y using theNMI categorization and the gender of the child with asensitivity of 92 and positive predictive value of 81(specificity 47 and negative predictive value 70) (5).
