Conditional purging

• Create a worklist filter.

• Click the Other Lists tab.

• Click the button in the Purge column for the new worklist filter.

• Select Enable, set parameters and click Configure. 

To automatically remove studies from the server based on specific matching criteria, set up an auto-purge action, as follows:

1. Create a filter identifying what you want downloaded to your workstation.

2. Go to the Other Lists page, and click the Purge column for the filter.

3. Click on Enable.

4. If you want to apply the purge to existing data, click on Apply To Current Content.

5. Enter the maximum number of studies to process each cycle in Batch size. An empty batch size value disables the limit setting and all studies matching the filter criteria will be executed during the action cycle.

6. Set the time you want the studies to be removed.

7. Check Keep Report to delete everything in the study except the report objects, private internal objects and key image objects.

8. To delete the studies permanently from all servers in the dotcom, check the Immediate box.

9. Click on Configure.

To define the specific objects to remove from the studies matching the filter defined in Step 1, continue as follows:

1. Click the Purge Matching Objects box. The expanded configuration options appear in the configuration panel.
2. Select the criteria for the objects within the study you wish to select. The following fields are available:
• Attachment Type: Identifies the Document Type of the attachment.
• Conversion Type: Identifies the type of Secondary Capture attachment.
• Modality: Modality of the objects to purge.
• Series Description: Purge series matching the entire string value.
• SOP Class: Purge objects by SOP class UID.
3. Use the Preview button to see which objects match your criteria. On the preview page, click the Show Details button, , to select a study from the list at the top to see which objects in this study match the criteria. To return to the configuration page, click the Back button, , at the top of the study list.

When purging matching objects, the following occurs:

• The delete defaults to “Immediate”. It is recommended that partial deletes be purged using this setting.

• The Keep Report option is disabled. The keep report option is available only when purging the entire study.

• The Mark As Deletable Only option is disabled. This option exists when the server is configured with an “external” archive. Marking studies as deletable applies to the entire study only.

Note that PB Report objects, PB Dictation objects and Basic Text SR objects cannot be purged using the individual purge feature. The only way to remove them is to purge the entire study.

The individual purging feature is mutually exclusive of the Keep Reports option and the Mark As Deletable Only option.

The logs will contain an OBJECT level entry with action of delete for each object purged from a study, and a STUDY level entry for a partial delete. The name of the worklist filter (list) used in the delete is contained in the Partial Rules field on the Logs page.

eRAD PACS Enterprise solutions maintain a single list of studies. There is no difference between studies on the worklist or in the archive. The delete action permanently removes all copies of a study from the server.

The purge action only works on data in the primary (worklist) database. Once a study is submitted to a near-line or third party archive, it cannot be removed by this action.
