Checking a protocol version

Research documents may carry version dates or identifiers. Ask the study team which version applies to you and whether an update changes the consent discussion. Do not assume an older printed copy is still current.

A version number, date and document title can help distinguish two copies, but they do not by themselves tell you which version applies to your participation. A printed file may remain useful as a record even when instructions have changed. Ask the study team to identify the current approved participant documents and explain any update that affects you. Do not discard a signed copy simply because another document looks newer.

A revision may affect wording, procedures or other study details. Ask the team to explain the changes and whether another consent discussion is needed. Keep the explanation with the relevant document if appropriate. Never combine instructions from two versions on your own. This article does not verify protocol approval or interpret a particular study requirement.

• What is the title and date of the copy I have?
• Which approved participant document currently applies to me?
• Do any changes require a new explanation or consent discussion?

As a document exercise, place two version dates side by side and note the title of each file. Do not label the later date authoritative without confirmation of what document it is and whether it applies. A signed consent form and a general study summary may not serve the same purpose.
