SURGERY DESIGN
‘QCOR is a novel solution that can increase the numbers of operating rooms by multiples of four without elongating the walking line of nurses.’
about the elevators not working in the event of a power cut. However, in such cases, the function of operating rooms themselves will be equally compromised even in the flatly arranged operating rooms. Today, elevators are considered to be the most reliable transportation system. In recent hospital designs hybrid operating
rooms with space for CAT and MRI room are necessary. However all of them require a large working space over 100 m2
in inner size which
makes it difficult to make such a large room. If a space is needed, a special room needs to be constructed in a different area. In our QCOR, a large room can be easily constructed without change of the general shape by connecting two facing rooms. As mentioned before, the difference of the
building costs was not calculated. Stratification of the operating rooms is thought to be particularly effective in Japan owing to the extremely high land prices. We did not examine the running cost of our system either. It is necessary to really calculate these costs. It also is necessary to really perform a building design. These are our future aims.
Conclusion Our concept of stratified QCOR is a novel solution that can increase the numbers of

operating rooms by multiples of four without elongating the walking line of nurses. It can also provide isolated passages for people, supply of sterilised instruments and materials, and contaminated instruments using private elevators, preparation room with a supply dumbwaiter, and collection outer corridor. A large room can also be created simply by connecting two facing rooms. Although the building cost and the running cost really does need to be calculated, we
believe that this concept makes a great improvement to the functionality of operating rooms.
