St Gart's Brookside Hospital was a general hospital in London, England, a part of the Euro Combine Health Administration. The Seventh Doctor and Ace infiltrated the institution in October 2021 to investigate its "C-Programme" and its possible connection to a Cyberman invasion. Ace pretended to be a member of the hospital's human resources division. She met Thomas Hector "Hex" Schofield, a nurse on staff there. Hex's help with the Cyber-threat earned him a place in the TARDIS at the end of the investigation.

People associated with the hospital Edit

Members of staff at the time of the Doctor's visit included Hex, Dr. Stephen Farrer, executive security officer David Garnier, and Dr. Mark Matthias. Patients included the anonymous Subject One, and Damien Boyd (a former flatmate of Hex). Somewhere between patient and employee was Polk, a former patient of another division of C-Programme, who at times seemed to work for Dr. Farrer, and at other times was used as a basis of comparison with Subject One.
