This is the hardest situation in the role

The protocol says one thing and your clinical judgment says another. A participant meets a continuation rule and you think they should stop. A required procedure seems unwise today.

There is a right answer and it is uncomfortable.

Safety comes first

Where there is an immediate hazard to a participant, you act to protect them. You do not withhold necessary treatment because a protocol did not anticipate it.

This is not a judgment call about how serious it is. If it is immediate, you act.

Then it is documented and reported

A deviation made for participant safety is still a deviation. It is reported promptly, with the clinical reasoning.

A sponsor reading "dose withheld: participant had a temperature of 39.1 and new confusion; protocol requires continuation; investigator judged continuation unsafe" understands immediately. That record protects the participant, the site and the study.

Where it is not immediate, consult

Most disagreements are not emergencies. A borderline result, a symptom you are unsure about, a participant who is struggling.

Discuss with the PI and, where the protocol allows, with the medical monitor. Studies have a 24-hour medical contact for exactly this.

Do not quietly do it your way

The most damaging version is not a deviation. It is a series of small, reasonable, undocumented departures that make a site's data incomparable with everybody else's.

If you think a protocol requirement is clinically wrong, say so through the channel that can amend it.

Do not change the record to fit

Adjusting a value, a time or an assessment so that a decision looks compliant is falsification, regardless of how sound the clinical reasoning was.

The participant's own wishes belong here too

A participant may decline a procedure while remaining in the study. That is their right, it is recorded as a refusal, and it is not a withdrawal unless they say so.
