Standard Operating Procedure for Source Documentation Standards (ALCOA/ALCOA+)

Purpose

The purpose of this SOP is to define the standards for creating, maintaining, and verifying source documentation in clinical trials based on ALCOA/ALCOA+ principles. Proper documentation ensures data integrity, subject safety, regulatory compliance, and inspection readiness.

Scope

This SOP applies to investigators, study coordinators, monitors, and other clinical trial staff responsible for documenting trial-related information. It covers paper and electronic source data including medical records, laboratory reports, subject diaries, and case report forms (CRFs).

Responsibilities

• Principal Investigator (PI): Ensures all source data meet ALCOA/ALCOA+ standards and verifies entries against CRFs.
• Study Coordinator: Records trial-related information accurately and maintains source documentation in ISF.
• Monitors (CRA): Verify source data against CRFs during monitoring visits.
• Sponsor/CRO: Provides guidance and oversight to ensure compliance with documentation standards.
• Quality Assurance Officer: Reviews source documentation for compliance during audits and inspections.

Accountability

The PI is accountable for ensuring all trial source documentation complies with ALCOA/ALCOA+ principles. Sponsors are accountable for ensuring oversight and continuous monitoring of documentation practices.

Procedure

1. ALCOA Principles
Attributable: Each entry must identify who recorded it.
Legible: Data must be clear and readable.
Contemporaneous: Data must be recorded at the time of observation.
Original: Records must be the original or a certified copy.
Accurate: Entries must reflect the true findings without alteration.

2. ALCOA+ Additional Principles
Complete: Include all data, even errors (with corrections documented).
Consistent: Ensure uniformity of data over time.
Enduring: Records must be preserved over the trial duration and retention period.
Available: Documentation must be accessible for review by monitors, auditors, and inspectors.

3. Documentation Practices
Record data immediately at point of observation.
Correct errors with a single line, initial, and date; do not erase or overwrite.
Ensure electronic systems have audit trails.
Document late entries clearly with justification.

4. Verification and Monitoring
Cross-check source documentation with CRFs.
Monitors verify accuracy and completeness during site visits.
Discrepancies must be resolved and documented in Source Data Verification (SDV) Log (Annexure-1).

5. Archiving
Retain source documents in ISF/TMF as per regulatory timelines (minimum 5–25 years based on region).
Ensure security, confidentiality, and controlled access.
