Create a worklist filter.
Click the Other Lists tab.
Click the button in the Retrieve column for the new worklist filter.
Select Enable, set parameters and click Configure.
A worklist action exists for scheduling the retrieval of prior studies from an archive. By default, when no retrieve action exists, the archive retrieve rules apply immediately when the order or new study arrives on the server. If a retrieve action exists, the prior retrieve rules get applied when the order or study match the defined filter. The most practical use of the retrieve action is when a connected RIS submits orders to the PACS well in advance of the scheduled procedure date. In this case, a filter consisting of orders (State is Ordered) and the scheduled procedure start date (Scheduled Date) is less than twelve hours or maybe one day in the future.
To set up a retrieve action:
Create the filter specifying which studies to check for priors.
Click on the Other Lists tab.
In the row corresponding to the defined filter, click on the link in the Retrieve column to bring up the action configuration page.
Check the Enable checkbox.
Check the Apply To Current Content checkbox to initiate the retrieve rules for all studies that currently satisfy the filter’s criteria. Leave it blank to apply the retrieve rules only to new orders and studies.
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.
Set the Scheduling option to specify when to execute the retrieve action. Immediately means initiate the retrieve process as soon as a new order/study matches the filter criteria. Daily means initiate it at the defined time each day.
Click the Configure button.
If a limit is defined, the system maintains a first-in-first-out queue. Studies that match the filter criteria at the time the action cycle occurs are appended to the end of the queue. Then the system applies the action to studies at the head of the queue. The action’s Batch Size setting defines the number of studies processed. The procedure repeats with each action cycle until the queue is empty.
Note: Expanding the filter list to include priors is unnecessary. This action automatically includes priors for the study returned by the filtered query.
