Defining “Route Priors” Logic

Verifying that Prefetch is Enabled

The capability to route priors assumes that ‘prefetch’ is enabled. Prefetch is generally enabled at sites using VistARad.

You can verify that prefetch is enabled by checking the following settings.

ƒIn the Protocol File (#101), use FileMan to verify that MAGJ PREFETCH/SEND ORM is defined as a Subscriber to the RA REG protocol.

ƒIn the APPLICATION PARAMETER File (#771), verify that MAGJ CLIENT is set to “Active.”

Note: The PREFETCH ACTIVE? setting in the VistARad Site Parameters File (#2006.69) does not affect the automatic routing of priors.

For more information, refer to chapter 3 in the Imaging System Installation Guide.

How Prior Exam Routing Works

The logic for automatically routing prior exams is triggered when a prior study statement is used in a routing rule. The baseline logic for routing priors is:

For each exam being automatically routed, also route up to one matching prior exam up to 1800 days (about five years) old.

This logic is stored in the MAG RAD PRIOR EXAMS LOGIC File (#2006.65). In a nutshell, this file is used for three things:

1It is used to identify, based on procedure name/CPT code, what qualifies as a ‘prior exam’.

2It is used to determine the maximum number and age of exams to automatically route as priors.

3It is used to determine the maximum number and age of exams to retrieve from the jukebox for VistARad prefetch.

Note: Numbers 1 and 3 above are pre-existing functions. Number 2 is a new function introduced in Patch 51.

Altering “Route Priors” Logic

To alter the logic used for automatic routing of prior exams, you will first need to identify the procedure name/CPT code of the current exams in question. Then you will need to edit the MAG RAD PRIOR EXAMS LOGIC File (#2006.65) as described below.
