A cohort of very low birthweight infants (less than 1500 g) born in 1979-81 from a geographically defined area was followed up, and a costing of the initial admission to the neonatal intensive care unit was made. A four point scale for the severity of disability was used and estimation of the costs of education and full time residential care was made and discounted at 5% over the appropriate period. During the three years a progressively increasing proportion of infants survived, and this was associated with an increasing proportion of disabilities among the survivors. If costs are related to outcome up to the age of 4 they get progressively less over the three year study period. After the age of 4 the costs of special education and residential care dominate, and the cost trend is reversed.
对1979年至1981年在一个地理区域内出生的一组极低出生体重婴儿（体重不足1500克）进行了随访，并对新生儿重症监护病房的首次入院费用进行了估算。采用了一个四分制的残疾严重程度量表，并对教育和全日制寄宿护理的费用进行了估算，并在适当期间按5%进行了贴现。在这三年中，存活婴儿的比例逐渐增加，而这与幸存者中残疾比例的增加有关。如果将费用与4岁之前的结果相关联，那么在三年的研究期内，费用会逐渐减少。4岁之后，特殊教育和寄宿护理的费用占主导地位，费用趋势发生逆转。
