The story was supported by the GMC's internal press office, which held a Q&A format press briefing at the Science Media Centre and issued an embargoed press release to all national health correspondents and news planners last Wednesday.

Guardian columnist Ann Robinson discussed the story last Thursday, saying: 'Getting drugs right in hospital is a minefield.' The BBC also ran the story on BBC Breakfast, BBC Radio 5 Live, BBC Radio 4 and its Health website.
