8 Normally, patients undergoing surgery remain stationary with surgeons and other theatre staff performing their tasks around the patient. A surgeon frustrated by spending time drinking tea while patients were prepared for surgery redesigned the process so he moves continually between two theatres. While he is operating on a patient in one theatre, his anaesthetist colleagues are preparing a patient for surgery in another theatre. After finishing with the first patient, the surgeon ‘scrubs up’, moves to the second operating theatre and begins the surgery on the second patient. While he is doing this, the first patient is moved out of the first operating theatre and the third patient is prepared. What are the advantages and disadvantages of this layout?
