1. Clinical anchor
State the patient context, time course and dominant problem in one sentence.
2. Key discriminators
Identify the small number of positive and negative features that separate the leading diagnoses.
3. Pathway and mechanism
Explain how the mechanism produces the clinical findings. This prevents disconnected memorisation.
4. Investigations
Separate bedside or first-line tests, confirmatory tests and tests used to assess severity or complications.
5. Management
Separate immediate stabilisation, disease-specific treatment, definitive management and monitoring.
6. Traps and red flags
Name the plausible mistake and the finding that changes urgency.
Worked example: severe hyperkalaemia
Anchor: CKD patient with weakness and ECG change.
Discriminator: global peaked T waves and widening QRS.
Mechanism: extracellular potassium alters cardiac membrane excitability.
Investigations: urgent repeat potassium if needed, continuous ECG and cause assessment.
Management: IV calcium for ECG change, then shift and remove potassium.
Trap: giving insulin first without immediate membrane protection.
