Question: Does inclusion of turnover time influence identification of surgical services that over- and underutilize allocated block time?
Answer: Turnover time is difficult to determine from existing operating room information systems. This study determined the use of block time with and without turnover time for each surgical service in a large academic hospital. Turnover time did not change identification of surgical services that over- (one service) or underused (three services) allocated block time.
Output:
no
