Pre-test probability of DVT. Does this leg need ultrasound or just a D-dimer? Answer it in 60 seconds.
Vascular
Wells Score — PE
Pre-test probability of pulmonary embolism. Go straight to CTPA or D-dimer first? This decides it.
Respiratory
CURB-65
Pneumonia severity. Home, ward or ICU? Five criteria, one confident decision. Every respiratory rotation.
Cardiology
CHA₂DS₂-VASc
Stroke risk in AF. The score that decides anticoagulation on every cardiology ward in the world.
Hepatology
Child-Pugh Score
Chronic liver disease prognosis. Class A, B or C — determines surgery risk, transplant listing, drug dosing.

BMI Calculator
Body Mass Index with full WHO classification and clinical action plan. Used in every single patient assessment.
Renal
eGFR — CKD-EPI

Infectious
Centor Score
Streptococcal pharyngitis probability. The evidence-based answer to "should I prescribe antibiotics?"

Surgery
Ranson's Criteria
Pancreatitis severity at admission and 48 hours. Predicts complications, ICU need and mortality risk.
Respiratory
PSI / PORT Score
Pneumonia Severity Index — more detailed than CURB-65. Use both together for confident admission decisions.
