How is data integrity ensured in health information systems during audits?

• A. By restricting access, performing regular backups, validation, and verifying data accuracy
• B. By openly sharing all data with guests
• C. By ignoring data validation
• D. By printing data and discarding digital records

Answer: (A)

Maintaining data integrity in health information systems during audits relies on safeguarding data from unauthorized changes and ensuring its accuracy throughout the data lifecycle. The best approach combines restricting access to prevent tampering, performing regular backups to recover from loss or corruption, validating data at entry and processing to enforce correct formats and rules, and verifying data accuracy against source records during audits. Together, these controls create a reliable, traceable trail that supports trustworthy audit results. Sharing data openly with guests violates patient privacy and security requirements, so it undermines integrity. Ignoring data validation allows erroneous data to enter the system, which undermines trust. Printing and discarding digital records destroys the audit trail and makes digital integrity impossible to verify.
