I wish we'd been taught with the same logical approach as your frameworks – then we wouldn't have to rote learn or just rely on protocols. Trying to change my approach now with your frameworks.

The Newsletter
Every week receive Clinical Decisions Explained
Every week, Clinical Decisions Explained walks through a real case from acute medicine.
Not just the diagnosis. The reasoning.
What to consider first. What to rule out. Where the traps are. How to think when the presentation isn't textbook.
It's the kind of teaching you'd get from a good registrar on a quiet night – except it arrives in your inbox every week.
Case-Based Reasoning
Real cases from the acute take. See how the systematic reasoning method works in practice, not just theory.
The Method, Made Visible
The thinking behind the structure: how to move from a symptom to a diagnosis, one deliberate step at a time.
On-Call Survival
Practical pearls for working on-call – the stuff nobody teaches you in medical school.
