Working diagnosis

Also called Provisional diagnosis, Impression

A working diagnosis is the explanation you act on until new information confirms or replaces it, usually the top of your differential.

Why it matters in a workup

Name it and say how confident you are. The next doctor then knows what you are treating as true and what would change your mind.

When you cannot name one, say so and say what you need to find out.

Example

Typical angina, suspected chronic coronary syndrome, pending cardiology assessment.

Put it into practice

  • Name it at the top of the assessment
  • State your confidence
  • Say what result would change it

Frequently asked questions

Is a working diagnosis the final diagnosis?
