Objetivo Estimar os custos diretos de internações de recém-nascidos prematuros de mães adolescentes em um hospital público.Métodos Estudo de estimativa de custos realizado entre 2009 e 2011, no qual os custos hospitalares diretos foram estimados para recém-nascidos prematuros de mães adolescentes, com 22 a 36 6/7 semanas de gestação, e tratados na unidade neonatal do hospital.Resultados Em 2006, o hospital em estudo teve 5.180 partos; 17,8% (922) foram de mães adolescentes, e 19,63% (181) recém-nascidos foram admitidos na unidade neonatal. Dos 181 neonatos, 58% (105) eram prematuros, dos quais 80% (84) foram incluídos neste estudo. Estes 84 recém-nascidos totalizaram 1.633 dias de tratamento hospitalar, a um custo total de US$195,609.00. Aproximadamente 72% desse custo total (US$141,323.00) referiu-se a serviços hospitalares. Os custos médios diários variaram de US$97.00 a US$157.00.Conclusão Este estudo demonstrou que o custo médio de recém-nascido prematuro de mães adolescentes foi US$2,328.00 e variou de acordo com o peso ao nascimento. Para recém-nascidos com peso <1.000g ao nascer, o custo médio foi US$8,930.00, e para os que pesaram >2.000g foi de US$642.00. O custo hospitalar total estimado para os 84 neonatos no estudo foi de US$195,609.00.

Objective : To estimate the direct costs of hospital stay for premature newborns of adolescent mothers, in a public hospital.Methods : A cost estimate study conducted between 2009 and 2011, in which direct hospital costs were estimated for premature newborns of adolescent mothers, with 22 to 36 6/7 gestational weeks, and treated at the neonatal unit of the hospital.Results : In 2006, there were 5,180 deliveries at this hospital, and 17.8% (922) were newborns of adolescent mothers, of which 19.63% (181) were admitted to the neonatal unit. Out of the 181 neonates, 58% (105) were premature and 80% (84) of them were included in this study. These 84 neonates had a total of 1,633 days in-patient hospital care at a total cost of US$195,609.00. Approximately 72% of this total cost (US$141,323.00) accounted for hospital services. The mean daily costs ranged from US$97.00 to US$157.00.Conclusion : This study demonstrated that the average cost of premature newborns from adolescent mothers was US$2,328.00 and varied according to birth weight. For those weighing <1,000g at birth, the mean direct cost was US$8,930.00 per stay as opposed to a cost of US$642.00 for those with birth weight >2,000g. The overall estimated direct cost for the 84 neonates in the study totaled US$195,609.00.
