While "Casualty" 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. Although both shows are set in the same hospital, the "Casualty" set in Bristol was not large enough to encompass the surgical ward and operating theatre required
