Mikael Krogerus and Roman Tschäppeler explore how information, timing, and reflection shape decisions. This talk provides a useful outside perspective for clinicians who often must act before certainty arrives.
“
When do you know that you know enough?

Why this matters
In emergency medicine, making decisions with limited information is what we do all shift, every shift. The challenge is knowing when more information will help and when we have enough to act. This talk explores that tension and addresses the temptation to keep looking for the perfect answer. It’s also a reminder that a bad outcome doesn’t necessarily mean we made a bad decision.
The connection in this talk to clinical practice comes down to a few questions: What are we still unsure about? Would knowing the answer change what we do? And do we need that answer before moving forward?
Connections to Decision School
Recognize when uncertainty is unavoidable and a decision still has to be made.
Ask whether another piece of information could change the plan, or whether it would only delay the decision.
Judge the decision by the information and reasoning available at the time, not only by what happened afterward.
Reflect on how timing can pull a decision toward acting too soon, waiting too long, or chasing a perfect answer.
