Background: Triage is performed for inpatient urgent surgery at the majority of hospitals and is determined by the degree of urgency as well as the time of surgical booking. It is possible that the postoperative course will be affected if, as a result of sharing resources among specialists, patients need to wait longer for semi-urgent surgeries. The purpose of this research is to investigate whether or not there is a correlation between the length of time before semiurgent surgery and the postoperative duration of stay in the hospital for neurosurgical patients
