Delete Actions (Configure Purge)

To automatically delete studies 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:

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

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

• Enable - enables the action

• Apply to 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

• Immediate - deletes studies immediately and permanently from all servers in the dotcom

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

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

The following fields are available:

• TODO: selectFilter: DOCT

• TODO: selectFilter: CVTP - identifies the type of SC attachment

• TODO: selectFilter: MODA - purge objects by modality

• TODO: selectFilter: SRDS -  purge series matching the entire string value.   

• TODO: selectFilter: SPID - purge objects by SOP class UID

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.

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.
