Patch PSS*1.0*227 provides the following enhancements to VistA:

- Enables auditing of drug file changes when a user modifies certain fields in the DRUG file (#50) through the Drug Enter/Edit [PSS DRUG ENTER/EDIT] menu option. This enhancement generates a message to a new mail group called PSS DEE AUDIT when these fields are modified. The message shows the date/time of the change, the name of the user who made the change, and before/after descriptions of the changed field(s).

In addition, a new Pharmacy Price Tracker function sends a separate audit message to the PSS DEE AUDIT mail group when the PRICE PER DISPENSE UNIT field (#16) is added or changed, or when the PRICE PER DISPENSE UNIT field is automatically updated by a change to the PRICE PER ORDER UNIT field (#13).
