Use the Relevant Prior Manager to configure rules that determine whether a study is a prior to be prefetched or autofetched. These rules prompt the system to retrieve prior studies to cache before the studies are needed. Priors are fetched only if relevant prior rules exist in Administration Tools.
 | Note: Relevancy rules can also be defined in the IMPAX Client. These Client rules define which studies are considered relevant, but do not cause them to be prefetched. More information on how Client and Administration Tools rules work together is provided in . |
To create or modify a relevant prior rule
On the Setup tab, click Relevant Prior Manager.
To create a new rule, click New.
or
To modify an existing rule, select it in the list of defined rules.
From the list, select the Modality to apply the rule to.
From the list, select the Specialty to apply the rule to.
For retrieval by specialty to work effectively, RIS procedure codes must be properly mapped into the radiology specialties through the Specialty Manager.
Select or clear the checkboxes defining the rules to apply.
Checkbox When selected Same Modality Retrieves relevant priors of the same modality as the current study. Note:
For prefetching based on visit scheduled, this option has no effect.
Oldest Relevant Retrieves the oldest study matching the rule options (including the Max Days value). Same Specialty Retrieves relevant priors of the same specialty as the current study. Only fetch key images if available Sends only the key images, associated C/GSPS objects, and KOSD DICOM objects. If the study has no key images, sends nothing. In the Max Number of Studies field, type the maximum number of relevant prior studies to retrieve (or leave the field blank).
In the Max Days field, type the maximum age of relevant priors to retrieve (or leave the field blank).
The maximum age is calculated from the date of the related study, not from the current date.
Click Save.
If configured, in addition to the local cluster, linked clusters will be searched for relevant prior studies based on the defined rule.
