A surgical instrument management system includes a first memory, a second memory, a third memory, and a first processor. The first memory stores user IDs associated in a one-to-one correspondence with users. The second memory stores instrument IDs associated in a one-to-one correspondence with surgical instruments. The third memory stores the instrument IDs, work information and work hours of work performed on the instruments each identified by a respective one of the instrument IDs, and the user IDs so that the instrument IDs, the work information, the work hours and the user IDs are associated with each other. The first processor extracts work information of one of the users identified by a corresponding one of the user IDs in a predetermined period, based on the user IDs and the work hours stored in the third memory.
