THEATRE DESIGN
observed in our hospital. Looking at theatre size for multi-subspecialty surgery, nevertheless, the ratio of 0.11 appeared to be far lower than 0.17. We would suggest that this highlights the difficulties in creating a universal model for collaborative surgery. In fact, the way that different surgical teams collaborate varies considerably between different hospitals, and changes as new technology emerges. Furthermore, these types of surgery are relatively rare. We do not believe that a universal model for this type of surgery is necessary at present. OT size may be influenced by the
theatre layout, which is based around the particular hospital’s cultural background.4 In the UK, HBN 265 sets out a different layout for operating theatres, and suggests that each should have its own anaesthetic room and integral scrub room. The minimum required OT size in HBN 01-01, Cardiac facilities8
was close
to the size set out in in the 2018 FGI guidelines regardless of the basic OT layout. Thus, there is a possibility that our model can be applied to the UK model.
Considering the user’s standpoint There are many measurement scales around which to base models of
appropriate OT size. Guidelines for operating theatres published to date have tended to be based around functionality and architectural structure, but have hardly incorporated the user’s viewpoint, as we have done in our study. In fact, we discovered that the minimum required space adhering to previous guidelines was almost identical to the ‘unsatisfactory’ OT size in the OT directors’ responses, while ‘satisfactory’ OT sizes were almost identical to the OT sizes proposed in our model. We believe that high user satisfaction is another major advantage of our model. User satisfaction is, of course, different
from the efficacy of the OT. The feedback obtained in our study could have been markedly different had we factored in different questions to our survey of surgical personnel. Nevertheless, our study sheds light on the user’s standpoint on OT design. Previous studies have focused mainly on OT cleanliness, rather than efficacy. Our model should be tested in terms of efficacy or functionality using OT performance in the future.
