Conclusions <32 weeks RGH 5 year cohort 2007-2011 86% of infants admitted survived to 2 yrs Health outcome available in 49% of survivors, all through standardised assessment Combined death or disability was 24% 76% of survivors assessed were free of moderate to severe disability Serious visual impairment was rare
Conclusions Data comparable to major studies BUT BEWARE Small numbers 51% of survivors not assessed
