To examine the clinical risk index for babies (CRIB) predictive value for hospital death; to identify the score variable with the best predictive value and to compare CRIB score capability to predict hospital mortality to birth weight, gestational age and base excess.
CRIB score was obtained through a prospective way from 100 newborns with birthweight of 1,500 g or less or gestational age less than 31 weeks, who were admitted consecutively to the Neonatal Unit of Hospital das Clínicas, Universidade Federal do Paraná.
Fifty-five newborns were females and 45 were males, the average birthweight was 1,078 +/- 0.277 g and gestational age was 29.2 +/- 2.8 weeks. Twenty-one patients died. The mortality rate in the CRIB groups 1, 2, 3 and 4 was, respectively 6.6%; 46.2%; 87.5% and 100.0%. The score accuracy for mortality was confirmed (area under the ROC curve=0.877) and the best score variable to predict hospital death was maximum base excess (area under the ROC curve=0.795). Compared with birthweight and gestational age, CRIB was significantly better to predict mortality.
Besides being useful to predict hospital death, CRIB was a simple score to be applied. Based on these results, we recommend its inclusion in the routine of neonatal units.
探讨婴儿临床风险指数（CRIB）对医院死亡的预测价值；确定具有最佳预测价值的评分变量，并比较CRIB评分预测医院死亡率与出生体重、胎龄和碱剩余的能力。
通过前瞻性方法，从连续入住巴拉那联邦大学临床医院新生儿科的100例出生体重1500g及以下或胎龄小于31周的新生儿中获取CRIB评分。
55例新生儿为女性，45例为男性，平均出生体重为1078±0.277g，胎龄为29.2±2.8周。21例患者死亡。CRIB分组1、2、3和4中的死亡率分别为6.6%、46.2%、87.5%和100.0%。死亡率的评分准确性得到证实（ROC曲线下面积=0.877），预测医院死亡的最佳评分变量是最大碱剩余（ROC曲线下面积=0.795）。与出生体重和胎龄相比，CRIB在预测死亡率方面明显更好。
CRIB除了有助于预测医院死亡外，还是一个易于应用的简单评分。基于这些结果，我们建议将其纳入新生儿科的常规工作中。
