title: Infants of very low birthweight. A 15-year analysis.
abstract: 357 babies weighing 501--1500 g were born alive at Hammersmith Hospital in 1961--75. 58.5% died in the neonatal period and 1.4% at 4--25 months of age. 1.4% of the total are untraced, 5.3% have major handicap, 5.6% have minor handicap, and 27.8% are apparently normal. There was no significant improvement in neonatal mortality in three 5-year periods, 1961--65, 1966--70, and 1971--75, except that more small-for-gestational-age babies survived in the last period than in the first. More of these babies survived than did babies whose birthweight was appropriate for gestational age. There was no significant improvement in the proportion of handicapped children among the very-low-weight liveborn babies throughout the 15-year period, despite increasing complexity of care.
