Research Ethics Approvals: Keeping the Paper Trail Straight
Ethics approval is not a single letter. It is an application, conditions, amendments and reports over the life of a study. How to keep that trail complete and easy to show.
Most research teams can produce their original ethics approval letter. Fewer can show, in one place, the version of the protocol it approved, the conditions attached, every amendment since, and proof that the study as run matches what was approved. That full chain is what a funder, a journal, an auditor or an ethics committee may ask for. The goal is simple: at any point, be able to show which approved version of the study was in force on any given date.
What belongs in the ethics record
- The application as submitted, with all attachments: protocol, information sheets, consent forms, questionnaires, recruitment materials.
- Correspondence with the committee, including requests for changes and your responses.
- The approval, with its reference number, date, expiry or review date, and any conditions.
- Every amendment: what changed, why, the date submitted and the date approved.
- Reports: annual or progress reports, adverse event or incident reports, and the end-of-study report.
- Other approvals the study depends on: site permissions, data-sharing agreements, approvals from other institutions.
Version control is the hard part
The classic failure is a researcher using last year's consent form because it was the one on their laptop. Every approved document needs a version number and date printed on it, a record of which approval covers it, and a clear status: current, superseded or draft. Superseded versions are kept, not deleted; you may need to show which form a participant signed in a given month. Keep a simple table:
| Document | Version | Approved | In use from | Superseded |
|---|---|---|---|---|
| Participant information sheet | 2.1 | Approval of amendment 2 | date | current |
| Consent form | 1.0 | Original approval | date | date |
Conditions are commitments
Approval letters often carry conditions: report within a set period, notify changes of lead investigator, store data in a certain way, destroy identifiers by a certain date. List each condition separately with a due date and an owner, and record when it was met. An unmet condition discovered at audit is worse than an honest late report.
Link approvals to what actually happened
The ethics file shows what you were allowed to do; the study records show what you did. They should agree. Each participant's consent should reference the form version used, and that version should have been approved on that date. For the consent side, see consent forms that survive an audit. For the day-to-day study record, see digital versus paper lab notebooks.
Dates to track
- Approval expiry or renewal date
- Progress report due dates
- Condition deadlines
- Planned end of study and final report date
- Data retention and destruction dates committed in the application
Put them in the calendar the whole team sees, with reminders well ahead. Expired approval is a common and entirely avoidable finding.
Keep it together, keep it after
Hold all of this in one study record, not split between a supervisor's inbox and a shared drive. When the study closes, the ethics file is retained for as long as your institution or funder requires, which is often years after publication, so file it as a whole and note its review date. Rules on retention vary by institution and jurisdiction; check yours.
