are holby city and casualty set in the same hospital
Holby City Holby City was created by Tony McHale and Mal Young as a spin-off from the BBC medical drama Casualty, which is set in the emergency department of the fictional Holby City Hospital.[4][5] Young wanted to explore what happened to patients treated in Casualty once they were taken away to the hospital's surgical wards.[6] While Casualty's scope is limited to "accident of the week" storylines about patients entering hospital, Holby City allowed the possibility of storylines about long-term care, rather than immediate life and death decisions.[7] The series was commissioned by BBC One Controller Peter Salmon, and began airing on BBC One on 12 January 1999.[8][9]
Grey's Anatomy Grey's Anatomy follows the lives of surgical interns and residents at the fictional Grey-Sloan Memorial Hospital (formerly Seattle Grace Hospital, Season 1–6, Seattle Grace Mercy West Hospital, Season 6–9, and then Grey-Sloan Memorial Hospital, Season 9–present), as they gradually develop as seasoned doctors, with the help of their competent attending mentors and chief of surgery. Each installment, typically, begins with a voice-over narrative from Meredith Grey or a season regular, foreshadowing the theme of the episode.[79][80] Each season tends to represent the physicians' academic year, with each completed year qualifying the residents at a level higher in the surgical field.[81] The season will always end with a finale, typically related to a dramatic event such as a death or character departure.[82] Most installments revolve around the doctors' everyday lives as surgeons, but the show also emphasizes their personal, rather than professional, lives.[79] The series sets aside medical ethic concerns to focus on character development and relationships. Although the physicians treat the illnesses of their patients, often through complex surgeries, they display competitive spirit and seek praise.[83]
