Delete Actions (Configure Purge)

To automatically delete studies or specific matching objects from the server, set up a delete action. An example of this is when specific studies acquired by some modality or from a specific institution need to be deleted.

To enable the purge action:

Create and save a worklist filter
Go to Worklists/Other Lists and find the created filter
Select the Configure Purge icon
Make the desired changes and select the Configure icon

A Configure Post Process page will appear for the selected worklist filter:

Process current content - purge will consider all existing data on worklist

leaving clear will apply to future studies only

Batch size - maximum number of studies to process each cycle

an empty value disables limit setting and all studies matching filter criteria is executed during action cycle

Scheduling - performs purging immediately in 5 minute cycles or at a specific time on the day.
Include priors - instructs server to include priors
Keep report - purge everything except the report objects
NOTE: Checking the Keep reports checkbox will un-check the Purge matching objects checkbox and change Delete mode to Simple.
Checking either the Purge matching objects checkbox or changing Delete mode to Immediate or Obsolete will un-check Keep Reports
Delete mode- Simple, Immediate, Obsolete

Simple: deletes the study from the local server.
Immediate: deletes studies immediately and permanently from all servers in the dotcom.
Obsolete: mark the objects obsolete so they cannot be viewer or retrieved from an archive.

Purge Matching Objects - defines the specific objects to remove from the studies matching the filter

When the Purge Matching Objects box is enabled, an expanded configuration box appears.

.Click the Add filter icon then choose from filter section values.

The filter sections available are:

Filter section	Description
Attachment Type	Identifies attachment types as defined in Admin/Document Types. See Document_Type_Configuration
Conversion Type	Identifies the type of SC attachments.
Modality	Modality of the objects to purge.
Series Description	Purge series matching the entire string value
SOP Class	Purge objects by SOP class UID

Before proceeding any further, it is a good idea to verify if the objects you intend to purge are captured properly with the applied filter. To verify them, click the Preview button. The study list displayed represents the contents of the saved worklist and not the filtered objects. Click on a study row to expand it. Matching objects that match the filter are displayed below the study. Tooltips are available when hovering the mouse cursor over object icons. Confirm the objects match the desired purge filters before proceeding.

When purging matching objects, the following occurs:

Delete defaults to Immediate

It is recommended that partial deletes be purged using this setting

Keep Report option is disabled

The keep report option is available only when purging the entire study

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.

Whether specifying select objects or purging the entire study, click Configure to finish.

Note: PB Report objects, PB Dictation objects and Basic Text SR objects cannot be purged using the individual purge feature and must be removed by purging 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.

See: Logs

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.
