title: The Northwestern University Twin Study. V: Twin deliveries at Prentice Women's Hospital and Maternity Center, 1978-83.
abstract: Two hundred fifty-one twin deliveries between January 1, 1978 and June 30, 1983 at Prentice Women's Hospital and Maternity Center were reviewed. Cases were excluded if birth weight was less than 500 g, if gestational age was less than 26 weeks or if an antenatal fetal demise had occurred. Maternal demographic characteristics, delivery data and infant characteristics are described. The effect of providing care to a high-risk population of mothers in whom approximately 60% either deliver their infants preterm or with a birth weight of less than 2,500 g is discussed in terms of costs of care.
