Revised Geneva: sum of all weighted items (0–22+) Simplified Geneva: each item = 1 point (HR ≥75 = 1 regardless of level) Both validated in outpatient and ED populations
Algorithm: Low probability → D-dimer: if negative, PE excluded. If positive → CTPA. Intermediate/High probability → CTPA directly. PERC rule applicable for low-probability patients with all 8 PERC criteria negative.
