Reason from what is known
Use the information currently available. Do not fill gaps with assumptions simply because a detail would make the case easier to explain.

Working with evolving clinical information
Patient information may become available as a case unfolds. Use the information currently available, distinguish documented findings from assumptions, and revise your clinical reasoning when new evidence emerges.
Name uncertainty
Separate documented findings, patient report, collateral information, clinical inference, and questions that remain unanswered.
Preserve the timeline
Earlier impressions remain part of the reasoning record. New information may strengthen, weaken, or redirect them.
Revise transparently
Changing a formulation is appropriate when you can identify the new evidence and explain why it changes your thinking.
When the record changes
Pause, compare, and update
ConfirmWhat is new, where it came from, and whether it is reliable.
CompareHow the new evidence fits—or conflicts—with the existing record.
ReassessRisk, differential priorities, medical contributors, and treatment implications.
CommunicateWhat changed, why it matters, and what should happen next.
