Appropriate utilization of the operating room (ORs) requires a balance of many conflicting resources. This cannot be done without an understanding of the role of the OR in the finances of the institution, the missions of the institution, the actual data concerning utilization and costs.
Economics of the OR environment have changed dramatically in the past 10 years. For example, technological advances have led to the introduction and advancement of minimally invasive surgical procedures, which are purported to decrease morbidity, reduce hospital length of stay, and improve outcome. However, many of these procedures actually increase OR cost, time and supplies. The increased costs of minimally invasive surgery would not have been a problem in the past, due to the additional costs would have been easily adsorbed because of the large profit margin associated with surgical procedure. Under the implementation of the NHI, the DRG, capitated payment, and global budget, it is not surprising that this area is earmarked by many hospitals as a place to reduce expenses. Therefore, all of us working in the OR must be cost efficient and maximize productivity for long-term success.
Accurate estimation of operating times is a prerequisite for the efficient scheduling of the operating suite. In this study, authors sought to compare surgeons¡¦ time estimates for elective cases and to ascertain whether improvements could be made by statistical modeling.
The study was conducted in the GYN department at the VGHKS from 2000, Jan. to 2003, June. Author calculates operation time distribution (lognormal) and variance, and operation time finishing probability, costs, and comparing operating time difference between surgeons.
