Theatre Utilisation Session Details table - What does each column mean, and how are the values calculated?

To find the session details table, navigate to Surgery > Theatre Effectiveness > Utilisation and select the 'Session Details' button.

Column A - Theatre: The theatre assigned to the session.

Column B - Date: Date of the assigned session.

Column C - Day: Day of the week session is assigned.

Column F - Finish: Finish time for session.

Column G - Scheduled Minutes: Total amount of minutes assigned to the session.

Column H - Consultant: Consultant / Surgeon assigned to the session. This is reflected on the Theatre session planner.

Sessions where there has been no notification of the session holder will be called unassigned.

Column I - Specialty: The specialty assigned to the session.

Column J - Used Minutes: Total actual minutes "patients were in OR" or the theatre was used.

This will include both elective and emergency patients, and is only the minutes that were used within the allocated list - meaning any operating minutes prior to list start time or after list finish time are not included. Also patient changeover, any late start time, and early finish time is NOT included in this calculation.

Column K - Unused Minutes: This is unused minutes between the list start and finish times that are a result of late starts or early finishes.

Column L - Late Start Minutes: Total minutes after the list start time that the first patient entered the theatre (wheels in time).

Column M - Early Finish Minutes: Total minutes the list finished before the planned finish time. This is calculated from the time the last case left, until the planned list finish time.

Column N - Total Elective Elapsed Time: Total amount of  minutes used for elective cases in the session plus changeover time.

Column O - Actual Elective Time: Total amount of used elective minutes in the session plus minutes for early start plus minutes over run - excludes changeover.

Column P - No. of Elective Ops: Number of planned elective operations booked for the session.

Column Q - Total Emergency Elapsed Time: Total amount of  minutes used for emergency cases in the session, plus changeover time.

Column R - Actual Emergency Time:  Total amount of used emergency minutes in the session plus minutes for early start plus minutes over run - excludes changeover.

Column S - No. of Emergency Ops: Number of emergency (unscheduled) operations performed on the list.

Column V - Delay Minutes: Total number of delay minutes in the session.

Column W - In Session Changeover Minutes: Total number of changeover minutes for session.
