Abstract
The performance of three scoring systems for assessing mortality risk for neonates—clinical risk index for babies (CRIB), score for neonatal acute physiology (SNAP), and SNAP's perinatal extension (SNAP-PE)—were tested in the same set of patients. In 222 neonates weighing less than 1500 g at birth, CRIB scores were significantly better for assessing mortality risk than SNAP (p=0 017) or SNAP-PE (p<0·001), areas under receiver operating characteristic curves being 0·89 (SE 0·02), 0·82 (0·03), and 0 79 (0·03) respectively. Male sex was independently associated with poor prognosis after taking the CRIB score into account with a risk ratio of 2·75. We conclude that CRIB is the most useful score for comparing the performance of neonatal intensive-care units. New treatment methods, however, may require modifications to the system.
