Our institution is the School of Medicine at a private university, and the university hospital generates far more revenue than the total amount of student fees and subsidies. High proportions of the hospital revenue are from surgical procedures and intensive care. Through efficient management of operating rooms, the number of operations has increased, which has greatly contributed to the university management. Today, the operating rooms play an important part in the business of running the university.
On the other hand, payments for surgical procedures and intensive care are calculated based on the diagnosis procedure combination(DPC)system. Many institutions have increased the number of operations through effective use of operating rooms and implemented an ingenious measure to shorten the lengths of inpatient hospital stays without compromising patient safety. However, the recent increase in the demand for minimally-invasive surgery - such as robot-assisted surgery and the use of hybrid operating rooms - has presented new challenges to efforts to increase operating room efficiency and manage patient safety. In connection with minimally-invasive procedures, the efficiency and safety of the operating room as a whole are required more than ever, and economical efficiency should also be considered.
