Abstract
Objective To determine outcomes at age 3 years in babies born before 27 completed weeks’ gestation in 2006, and to evaluate changes in outcome since 1995 for babies born between 22 and 25 weeks’ gestation. Design Prospective national cohort studies, EPICure and EPICure 2. Setting Hospital and home based evaluations, England. Participants 1031 surviving babies born in 2006 before 27 completed weeks’ gestation. Outcomes for 584 babies born at 22-25 weeks’ gestation were compared with those of 260 surviving babies of the same gestational age born in 1995. Main outcome measures Survival to age 3 years, impairment (2008 consensus definitions), and developmental scores. Multiple imputation was used to account for the high proportion of missing data in the 2006 cohort. Results Of the 576 babies evaluated after birth in 2006, 13.4% (n=77) were categorised as having severe impairment and 11.8% (n=68) moderate impairment. The prevalence of neurodevelopmental impairment was significantly associated with length of gestation, with greater impairment as gestational age decreased: 45% at 22-23 weeks, 30% at 24 weeks, 25% at 25 weeks, and 20% at 26 weeks (PConclusion Survival and impairment in early childhood are both closely related to gestational age for babies born at less than 27 weeks’ gestation. Using multiple imputation to account for the high proportion of missing values, a higher proportion of babies admitted for neonatal care now survive without disability, particularly those born at gestational ages 24 and 25 weeks.Keywords
