We classify “fixed” activity as that which is done within a role but does not vary with other activity. An activity is fixed if it is still carried out regardless of an increase or decrease in patient number or workload.It is tempting to class fixed activity as admin or management, but it can also be recorded as “non-clinical activity.” Many administrative or management activities can be deemed to be variable if they flex alongside the variable workload and can therefore be added as a variable activity alongside clinical activity.
