Case Study: Review of Operating Room Utilization at Mayo Clinic Arizona (MCA)

摘要

The purposes of this case study was to determine if the operating suites at Mayo Clinic Arizona have been utilized efficiently in the past and identify if there is additional capacity within the current number of the operating rooms. The operating suite consists of 18 operating rooms that support 11 surgical services, 57 surgeons, and a tertiary care practice. The variables examined were: OR capacity, utilized OR capacity, allocated block- time for each service, use of allocated block-time by each service, allocated block-time released by each service, and block time lost. The data used was from calendar years 2006 and 2007. In some instances only 2007 data was used due to the unavailability of 2006 data. Analysis showed raw utilization of 61% and adjusted utilization of 74%. The highest three users of block time were general surgery, gynecology, and urology. In 2007, 946 surgical hours were lost due to delays in the first case of the day. The results of this study suggested the ORs were under utilized in 2006 and 2007 and capacity exists to support more cases in the future. Mayo Clinic would benefit from additional studies on process and efficiency within the ORs. Additionally, the organization should allocate block time to individual surgeons, verses services, to facilitate better understanding of utilization as well as to control staffing costs.
