- Updated
A participant may have a printed guide, a phone message and an application screen at the same time. Different explanations can make it unclear which step to follow. The site can plan how updated instructions reach the person and where uncertainty should be raised.
Define the workflow
Map materials and current versions to the relevant content owner. When sending an update, explain how earlier materials should be handled. Do not ask participants to rewrite previous entries to fit a new version; authorized staff assess any data or safety implications of the change.
Worked example
For example, a printed diary guide shows an old screen after an application update. The participant stops recording to avoid choosing the wrong option. Staff provide the current approved explanation, demonstrate the change and report the actual missing records through the appropriate route. The issue is not closed as carelessness.
Practical checks
- Compare printed, application and message-based explanations used for the same task together.
- Explain when a new version applies and how to handle earlier materials.
- Refer missing or different records caused by conflicting instructions without correcting them through guesses.
Decision and boundaries
A good process helps people find the right instruction and ask for help when unsure. A version update does not authorize an unreviewed change to research tasks; significant effects need appropriate assessment. Staff should not replace controlled content with their own telephone shortcuts. Recurrent confusion can prompt review of material distribution and training processes.
Frequently asked questions
- Is the latest message always the correct instruction?
- Verify the sender and content. Being newest does not by itself demonstrate that a message contains the approved version.
- Should data be rewritten after an old guide was used?
- Avoid retrospective assumptions. Authorized data and investigator processes should review actual use and its implications.
