How are 'In Session Changeover Minutes' calculated in the Theatre Utilisation Session Details table?

To find the session details table, navigate to Surgery > Theatre Effectiveness > Utilisation and select the 'Session Details' button. 'In Session Changeover Minutes' is Column W.

"In Session Changeover Minutes" refers to the total number of changeover minutes for session.

Please note that a session may have more than one case, therefore more than one changeover and the minutes will be total for all changeovers. No changeover is counted for the last case. E.g. 5 cases on list = 4 changeovers.
