The Null Drug Pair Removal process will change the status of any VA Drug Pair that contains a null Routed Generic to "Deleted" and remove the null drug pairs from their associated VA Drug-Drug Interactions. VA Drug Pairs end up with null Routed Generics because one or both of the Routed Generics that make up the Drug Pair has been deleted by FDB. PECS applies the FDB Routed Generic deletes as part of the weekly FDB-DIF update, so it is recommended that the Null Drug Pair Removal process be run weekly, after the FDB-DIF update completes.
The Administrator can initiate this process at any time by clicking the "Null Drug Pair Removal" button on the Administration tab.
When the process is complete, a message will appear at the top of the page to indicate that the process has completed.
Note: The Null Drug Pairs Customization Report can be used to identify approved VA Drug-Drug Interactions that contain null Drug Pairs. However, the Null Drug Pair Removal Process removes null drug pairs from any VA Drug-Drug Interaction, regardless of status. All VA Custom drug pairs that contain a null routed generic drug are updated as follows: the action status of the drug pair is changed to "Deleted" and the current action reason is "FDB Deleted," with the value of the FDB issue date when the custom drug pair was deleted. The FDB issue date is the date associated with the FDB update file that includes the deletion.
