The VAS application is a real-time web-based interface that has dependencies on VistA patient data. It provides a nationwide Health Insurance Portability and Accountability Act (HIPAA) compliant Audit Tracking Solution with the ability to track and report on access logs for patients' Personal Identifiable Information (PII)/Protected Health Information (PHI) data across all VistA instances. VAS users are Privacy Officers and Information Systems Security Officers (ISSO) and their authorized representatives who need the ability to view the log of Create, Read, Update and/or Delete (CRUD) operations on patient information to respond to Freedom of Information Act (FOIA), HIPAA, employee and Inspector General (IG) requests. This data originates from VistA and flows through in-memory database servers to be stored in the Veterans Affairs Enterprise Cloud (VAEC) Amazon Web Services (AWS). VAS web-based User Interface will access and display the data stored in AWS. The VAS 2.5.1 release contains the following changes to the VistA Audit Solution: Defect Remediations -------------------- VAS Privacy Officers with Unexpected Characters: VAS system was locking for Privacy Officers with an apostrophe in their name, this issue has been corrected so that internal communications can now read their name without causing the system to lock. Code solution for User Search Issue: Missing Employee: An issue with finding employees using exact case matching has been corrected so that employees will now appear in VAS when a user searches for an employee. Remove HashCode ID's from system: Removed reliance on hashed ID's in favor of unique identifiers augmented by hashes for patients, users, and locations in system. Remediation for User search issue when adding a space and middle name. Enhancements ------------- Various 508 minor updates.
