Evidence Based Practice and Quality Assurance
Background and Goal of Study: Allocation of block time and first starting times in operating rooms (OR) is a major challenge for OR managers and anesthesiologists (1). The aim of this study was to determine the utilization of allocated block OR time by surgical services with the inclusion of turnover time (TT).
Materials and Methods: Data were collected prospectively from OR schedule of five different surgical services between February 1, 2004 and March 31, 2004. Workday hours were identified from 8:00 AM to 4:00 PM (Monday through Friday) for forty days. Definitions of terminology are listed.
Total Case duration (TCD): The time when the patient is in the operating room.
Turnover time (TT): The period from previous patient out-rooms to the new patient in-room time.
Total operation duration (TOD): Summing the total case duration and turnover time.
Anaesthesia time: The period when the patient was in-room to the completion of anaesthesia preparation till the skin disinfection.
Results and Discussions: We evaluated 728 surgical cases that were performed in five operating rooms on 19200 minutes for each. There were no differences between surgical clinics in respect of OR utilization. Mean TT was 9 ± 1.14 and mean AT was 8 ± 0.70 (min ± SD) for all clinics. Results are shown in Table 1.
Conclusion: As a conclusion, turnover time can be reduced by improving the hospital and personal equipment. On the other hand type of surgery and anesthetic management are the other factors that affect the OR utilization.
