Since debuting in 2011, 24 Hours in A&E has captivated millions with real-life stories of life, love and loss, all of which is just a normal day for hospital staff.
24 Hours in A&E pretty much does what it says on the tin, following the events of a day at an accident and emergency department in London as staff deal with injuries from broken bones all the way up to life-threatening accidents.
The fly-on-the-wall documentary has won a Royal Television Society Award for Best Documentary, and has become a hit with viewers for its often emotionally-charged scenes depicting the bonds between patients, family members and hospital staff - not always with a happy ending.
Where is 24 Hours in A&E filmed?
24 Hours in A&E is now filmed in St George's Hospital, a teaching hospital in Tooting, London. It has one of the busiest A&E departments in the world, seeing 350 patients on average every day.
Did 24 Hours in A&E change hospital?
Yes - the first six series were filmed in King's College Hospital in Denmark Hill, Camberwell, before production moved to Tooting in 2014. The same hospital was used for the Louis Theroux documentary Drinking to Oblivion.
