The show has very few ties to its sister programme "Holby City", which began as a spin-off from "Casualty" in 1999, set in the same hospital. "Casualty" is shown weekly on a Saturday evening, which has been its time slot since the early 1990s. "Casualty"s exterior shots were mainly filmed outside the Ashley Down Centre in Bristol from 1986 until 2002 when they moved to the centre of Bristol for just over nine years. In 2011, "Casualty" celebrated its 25th anniversary; following that, for the Bristol finale, they filmed the

In July 2012, South London Healthcare NHS Trust was put into financial administration. A government report in 2012 recommended that three SLHT hospitals should be taken over by nearby NHS trusts and that the University Hospital Lewisham Accident and Emergency unit should close, with A&E patients instead going to the SLHT-run Queen Elizabeth Hospital in
