Date	Event	Description
8 January 2014	New citation required but conclusions have not changed	Added reference for ongoing randomised controlled trial of hydrocortisone in infants with postnatal age of 7 to 14 days
6 September 2013	New search has been performed	Updated searches 22 August 2013
7 August 2013	New search has been performed	This review updates the existing review "Late (> 7 days) postnatal corticosteroids for chronic lung disease in preterm infants". The short‐term benefits and side effects of postnatal corticosteroids are confirmed. Data from long‐term neurodevelopmental follow‐up are now available for 15 studies; small, non‐significant increases in cerebral palsy or major neurosensory disability were offset by small, non‐significant reductions in mortality. Hence data show little effect of postnatal corticosteroids on the combined outcomes of death with either cerebral palsy or major neurosensory disability.
7 October 2008	Amended	This review combines and updates the existing reviews "Delayed (> 3 weeks) postnatal corticosteroids for chronic lung disease in preterm infants" and "Moderately early (7‐14 days) postnatal corticosteroids for preventing chronic lung disease in preterm infants", published in the Cochrane Library, Issue 3, 2003. The short‐term benefits and side effects of postnatal corticosteroids are confirmed. Data on long‐term neurodevelopmental follow‐up are now available for 12 studies; small, non‐significant increases in cerebral palsy or major neurosensory disability were offset by small, non‐significant reductions in mortality. Hence data show little effect of postnatal corticosteroids on the combined outcomes of death with either cerebral palsy or major neurosensory disability.
7 October 2008	New citation required but conclusions have not changed	Prepared substantive update
1 April 2008	Amended	Converted to new review format
11 November 2002	New search has been performed	This review updates the existing review "Delayed (> 3 weeks) postnatal corticosteroids for chronic lung disease in preterm infants", published in the Cochrane Library, Issue 2, 2001. We have included additional long‐term neurodevelopmental follow‐up data for Harkavy 1989 (unpublished data provided by investigators) and Ohlsson 1992 (data obtained from Masters of Science thesis). With the addition of these follow‐up data, the previously reported non‐significant trend associating delayed steroid treatment with increased risk of cerebral palsy is somewhat less marked.
