CRA (OPS) common mistakes
CRA · Understand the traps and how to avoid them.
Checking only that the informed consent form has a subject signature and date, without verifying that consent was obtained before any study-specific procedure.
Candidates memorize the signature requirement but treat consent as a documentation artifact rather than a chronological process requirement.
What to do instead
Compare the consent date/time with the first study-specific procedure in the source record; use a consent checklist that confirms discussion, questions answered, signature, and copy provided before procedures.
Qualifying a site mainly on the investigator's reputation or expressed enthusiasm, without documenting adequate staff, recruitment potential, facilities, or IRB/EC feasibility.
Candidates confuse investigator credibility with site capability and skip structured qualification evidence.
What to do instead
Use a site qualification report that addresses staff roles and availability, recruitment plan, facilities/equipment, competing studies, and expected IRB/EC timelines, with documented evidence for each element.
At site initiation, verifying that SOPs and delegation logs exist but not confirming that delegated staff can actually perform their assigned tasks or that training is role-specific.
Candidates treat initiation as a checklist-completion exercise instead of a readiness assessment.
What to do instead
Observe or interview staff on role-specific procedures, compare the delegation log with actual tasks and training records, and document and resolve gaps before first subject enrollment.
Performing source data verification by matching CRF entries to source line by line but not assessing whether the source data are contemporaneous, legible, attributable, original, and accurate.
Candidates equate SDV with transcription checking rather than source data quality evaluation.
What to do instead
For each verified data point, confirm source quality and traceability, including who recorded it, when, and whether corrections have an audit trail; document source-quality findings separately from entry discrepancies.
Accepting photocopies or scanned records as source without confirming they are certified copies and without documenting where the original records are retained.
Candidates focus on whether a record exists rather than whether it is an acceptable source under the applicable standards.
What to do instead
Verify the certified-copy process, identify the original source location, and reconcile copies against originals; record any limitation and follow up before relying on the copy for SDV.
Deciding an event is not serious because the site does not label it as an SAE or because it is not on a protocol-specific list of expected serious events.
Candidates defer to site terminology instead of independently applying regulatory seriousness criteria.
What to do instead
Apply each seriousness criterion independently, including hospitalization, life-threatening, disability, congenital anomaly, and important medical event; document the criterion-by-criterion rationale for the final classification.
Waiting until source documentation is complete and queries are resolved before notifying the sponsor of an SAE.
Candidates conflate the monitoring workflow with the regulatory and protocol reporting clock.
What to do instead
Notify the sponsor immediately upon awareness within the protocol/sponsor timeline, then complete source documentation and follow-up reporting separately; record the awareness and notification dates.
Reconciling investigational product only by counting returned kits at close-out, without accounting for dispensed, used, destroyed, expired, and quarantined units or temperature excursions.
Candidates treat accountability as a physical inventory count rather than a full chain-of-custody reconciliation.
What to do instead
Reconcile received, dispensed, returned, destroyed, expired, and quarantined quantities against dispensing records; review temperature excursion assessments and document resolution of any discrepancy.
Closing a data query by changing the CRF or source to match the query text instead of investigating the correct value and documenting the resolution.
Candidates prioritize clearing queries quickly and assume the query text states the correct answer.
What to do instead
Review the original source and applicable protocol requirements, correct the record only when supported by source evidence, preserve an audit trail, and document the rationale for the resolution.
At close-out, leaving essential documents incomplete or assuming they can be collected after the close-out visit without a documented follow-up plan.
Candidates treat close-out as a single visit rather than the completion of a documentation and reconciliation process.
What to do instead
Perform a pre-close-out TMF/ISF reconciliation against the essential-document list, assign owners and due dates for missing items, and document retrieval, retention responsibilities, and final reconciliation before archiving.
