Operating efficiency of an emergency Burns theatre: An eight month analysis.

Abstract

The efficient use of operating theatres is important to insure optimum cost-benefit for the hospital. We used the emergency Burns theatre as a model to assess theatre efficiency at our institution. Data was collected retrospectively on every operation performed in the Burns theatre between 01/04/15 and 30/11/15. Each component of the operating theatre process was considered and integrated to calculate values for surgical/anaesthetic time, changeover time and ultimately theatre efficiency. A total of 426 operations were carried out over 887h of allocated theatre time (ATT). Actual operating time represented 67.7%, anaesthetic time 8.8% and changeover time 14.2% of ATT. The average changeover time between patients was 30.1min. Lists started on average 27.7min late each day. There were a total of 5.8h of overruns and 9.6h of no useful activity. Operating theatre efficiency was 69.3% for the 8 month period. Our study highlights areas where theatre efficiency can be improved. We suggest various strategies to improve this that may be applied universally.
