BackgroundKnowledge about the utilization of the operation theater (OT) is essential to improve its efficiency. This study evaluated the neurosurgical operation theater utilization in a neurosciences teaching hospital.MethodsData collected included OT start time, delay in start, anesthesia induction time, surgical preparation time, anesthesia recovery time, operating time, time between cases, and theater closing time.ResultsFive hundred thirty-seven surgeries were performed during the study period. The percentage of time used for anesthesia induction, actual surgical procedure, recovery from anesthesia, and theater preparation between the two cases were 8%, 70%, 6% and 5%, respectively. Fourteen percent of scheduled cases were cancelled. On 220 occasions (70.51%), theater was over-run. Late start contributed to loss of 8370 minutes (140 hours) of theater time.ConclusionsThis study identified the proportion of time spent on each activity in the neurosurgical OT. This knowledge is likely to facilitate better planning of neurosurgical theater schedule and result in optimal utilization.Copyright © 2015 Elsevier Inc. All rights reserved.
