What is an access/disclosure audit trail and why is it important?

• A. A log of staff vacation schedules.
• B. A log of who accessed or disclosed PHI, when, and what was accessed.
• C. A daily patient check-in list.
• D. A report of vendor deliveries.

Answer: (B)

An access/disclosure audit trail is a record that captures every instance PHI is accessed or disclosed. It logs who accessed the information, when it happened, exactly what data was accessed, and who it was disclosed to. This creates a traceable, verifiable history that supports accountability and security. Why this is the best fit: it directly describes the information that must be tracked to know who handled PHI and how, which is essential for detecting unauthorized access, investigating potential breaches, and demonstrating compliance with privacy and security rules (such as HIPAA). In practice, the systems that hold PHI generate these logs automatically, and privacy/security teams review them to monitor activity and respond to incidents. The other options don’t fit because they describe records unrelated to PHI access or disclosures (like staff vacation schedules, daily patient check-in lists, or vendor deliveries), which do not provide the necessary information about who accessed PHI, when, and what was accessed or shared.
