Holby City is set between the hospital's (AAU) Acute Assessment Unit situated on the ground Floor, General Surgical Ward – ‘Keller’ (third floor) and the hospitals Cardiothoracic Ward – ‘Darwin’ (sixth floor) wards, providing General and Cardiothoracic surgical care respectively. Holby expanded by adding "HolbyCare", a private healthcare ward led by Michael Spence adjacent to the existing Intensive Care Unit on the fifth floor. Former storylines have also focused around the hospital's Otter ward, providing paediatric care, as well as its maternity ward. Otter ward has not featured in the show since series 4, whilst the maternity ward ceased usage as a primary location in series 8.
