Outcome of extremely low birth-weight infants in relation to the hospital of birth.
There were 351 liveborn infants of birth-weight 500-999 g born in the State of Victoria in the years 1979 and 1980; 89/351 (25.4%) survived to the age of 2 years: 42 (47.2%) survivors were of gestational ages of 24 to 26 weeks and 47 (52.8%) were born at 27 to 32 weeks' gestation. Survival of these extremely low birth-weight infants was significantly better (71/245, 29%) for births in tertiary centres compared with those born elsewhere (18/106, 17%). Of the 351 livebirths, 69.8% occurred in 1 of the 3 tertiary centres. All 89 survivors were traced; 84 (94.4%) were assessed at the age of at least 2 years by a multidisciplinary team. Three children had been fully assessed at 1 year of age and paediatric reports were available for 2 children. The quality of survival of children born in tertiary centres was significantly better than those transferred to a tertiary centre after birth; the prevalence of serious functional handicap was 72.2% (13/18) for outborn children compared with 22.5% (16/71) for those born in tertiary centres. The prevalence of serious functional handicap in the inborn survivors was lowest (9/55, 16.4%) in singleton births who had been of appropriate birth-weight for gestation. A review of the 18 surviving outborn infants' records indicated that 6 (33.3%) could have been transferred to a tertiary centre in utero and for the 12 infants where birth in a tertiary centre was not feasible, improvements in the early neonatal care were possible in another 7 infants.
