You may only remove a medical event type from a cancer group if none of the patients registered with that cancer group have a medical event of that type recorded. Before removing a medical event type from the cancer group, you should remove all references to this medical event type from all of the patient records in the cancer group — or it is probably much more practical to simply deactivate the medical event type so that it no longer shows up as an option when entering future medical events instead of trying to remove all prior references to that medical event type — see Making an Event Type Inactive.

If you do attempt to remove a medical event type for an event that has actually been used and there are still patient records with that type of medical event, the result will be that the medical event type will remain in the medical event types list but it will be deactivated, making this process actually an alternate method for making a medical event type inactive.

To remove a medical event type from a cancer group:

Start the Cancer Group Administration utility. See Starting the Cancer Group Administration Utility for instructions on how to do this.

Select the Event Types tab on the CCR Administration window.

Click on the event type you want to remove from the current cancer group in the Event Types grid on that tab. The selected row will be highlighted in yellow.

Click on the — button above the grid. A dialog will open asking you to confirm that you really want to delete the event type.

Click Yes to confirm that you want to remove the event type. The dialog will close and the selected event type will be removed from the Event Types grid (and consequently from the cancer group).

If you change your mind and decide that you really don't want to remove the event type from the cancer group, click No and the dialog will close without any changes occurring in the database.

If there are patient records in the cancer group that have an event of this type recorded, although everything will function as expected above, the event type will not actually be removed from the Event Types grid. Instead, it will be reinserted into the grid and marked as inactive, just as if you had deactivated it instead of trying to remove it — see Making an Event Type Inactive. There will not be any alert message to inform you of this fact, however.
