A Simplified antepartum risk-scoring system.

The effectiveness of a simple antepartum risk-scoring system was evaluated in 2085 consecutive deliveries. Neonatal morbidity was observed in 42.1% of infants of mothers classified as high risk (score greater than or equal to 7) compared to 12.5% of infants of mothers classified as low risk (score less than 7). No neonatal deaths were observed in the low-risk group, compared with 34 in the high-risk group (P less than 0.001). Of all perinatal deaths, 88.6% occurred in the high-risk group. The perinatal mortality rates for low- and high-risk pregnancies were 7.2 and 63.3, respectively, per 1000 live births.
