Study Notes
Data Integrity Requirements
- Consistent application of data timestamps is essential in the expected sequence.
- Data should be recorded on controlled worksheets, laboratory notebooks, or electronic media.
- Data should be available and accessible for review/audit for the lifetime of the record.
21 CFR 211.194
- Date and time stamps are necessary to record data for the lifetime of the record.
- Record data should be attributable to the person who performed the activity.
Examples of Data Integrity Issues
- Failure to use unique login credentials (e.g., using a common user ID and password).
- Disabling audit trails makes it impossible to identify the person who performed the activity.
- Failing to log out of computers (e.g., HPLC machine) allows subsequent analyses to be performed by another user under the same login.
- Designing forms or records without space for recording observations or additional information.
- Having one person perform an activity and another person sign for it.
Legibility and Good Documentation Practices
- Handwriting should be readable by others.
- Any corrections should be done according to Good Documentation Practices.
- Data cannot be obscured with annotation tools.
- Data printouts should be readable, and not smudged or faded.
Availability of Data
- Data should not be hidden or deleted periodically (e.g., OOS results).
- Files should be backed up regularly to prevent data loss.
- Records should be archived until the end of their retention period.
- Validated spreadsheets should be backed up.
21 CFR Part 11 Overview
- 21 CFR Part 11 allows the use of electronic records and signatures instead of paper records and handwritten signatures.
- It applies to all FDA-regulated environments, especially when using computers for data creation, modification, archiving, retrieval, or transmission.
- It applies to records required by predicate rules (GLP, GCP, GMP) that impact patient safety.
Purpose of 21 CFR Part 11
- Ensure data is not corrupted or lost.
- Ensure data is secure.
- Ensure approvals cannot be repudiated.
- Ensure changes to data can be traced.
- Make attempts to falsify records difficult and detectable.
Types of Systems
- Closed systems: controlled access, limited access to data.
- Open systems: open access, no control over data access.
21 CFR Part 11 Requirements
- Validation.
- Device checks.
- Operational system checks.
- Accurate and complete copies.
- Accurate and steady retrieval.
- Limited access to systems and data.
- Authority checks.
- Electronic audit trail.
- Training and qualification of personnel.
- Accountability of signatures.
- Control over system documentation.
