The scene with people suspended from the ceiling in a hospital facility is a direct reference to a scene in the 1978 film "Coma", directed by Michael Crichton, from the novel by Robin Cook.
It also reminded me of a scene from an episode in 2007 which featured Daleks atop the Empire State Building in New York in the 1920s, who also had bodies on beds suspended from the ceilings. The situations are very different but there is some notable similarities in the two scenes. I think the "Coma" reference is more likely though.
The set used for the hospital (located in Upper Boat studios in Cardiff) was the same one used for The Oval Office in "The Impossible Astronaut"/"Day of the Moon", the Gangers' Acid Well Crypt in "The Rebel Flesh"/"The Almost People" and the birthing suite on Demons Run in "A Good Man Goes to War". The set was used for four different settings in the first half of Series Six.
