Source Documentation and Data Integrity Flashcards

Which of the following best describes the clinical research coordinator's (CRC) primary responsibility regarding source documentation?

Answer: Ensuring all protocol-required clinical activities are accurately and contemporaneously documented in source records

The CRC is primarily responsible for ensuring that every protocol-required clinical activity is documented accurately and in a timely manner in the appropriate source records.

In the context of ALCOA documentation principles, 'contemporaneous' means:

Answer: Documentation recorded at the time of the clinical event or immediately thereafter

Contemporaneous means that records are made at the time the event occurs or immediately after, minimizing reliance on memory and reducing the risk of documentation errors.

A database lock in a clinical trial signifies that:

Answer: All data queries have been resolved and the database is frozen to prevent further changes prior to statistical analysis

Database lock indicates that all data cleaning is complete, all queries are resolved, and the database is closed for modifications so that statistical analysis can begin on a finalized dataset.

Data cleaning in clinical trials primarily involves:

Answer: Identifying, querying, and resolving data discrepancies to ensure accuracy and completeness prior to database lock

Data cleaning involves systematically identifying discrepancies in CRF data, issuing queries to investigative sites for clarification, and verifying resolution to ensure the database is accurate and complete.

In clinical research, a data query is issued when:

Answer: There is a discrepancy, missing data entry, or unclear CRF field that requires clarification or correction by the site

Data queries are generated by monitors or data managers when CRF entries are missing, inconsistent, out of range, or unclear, prompting the investigative site to review and respond.

Why is the legibility of source data critically important in clinical research?

Answer: Illegible data cannot be reliably verified, audited, or used as credible evidence in regulatory submissions

Legible source data ensures it can be accurately read and interpreted by monitors, auditors, and inspectors, and used as reliable supporting evidence in regulatory submissions and inspections.

Which of the following scenarios would constitute a protocol deviation related to source documentation?

Answer: Failure to document a protocol-required clinical assessment in the source records at the time it was performed

Failure to document a protocol-required assessment in source records is a protocol deviation because the protocol mandated that the activity be captured, and the lack of documentation means compliance cannot be verified.
