Abstract
A great change has been made in the work of our operating room since we moved into a newly-built hospital several years ago. The number of operations has been increasing and most of the operations have been getting much more complicated year by year. Furthermore, there is a tendency for one operation to take longer and longer.
In ordes to make our work efficient, we took note of a “Container System”, and investigated the time is required to prepare machines and to tidy up after operations by a time-study method.
As a result, we have succeeded in reducing our working hours by 40%
