Grégoire Le Gal: Using an Age-Adjusted D-Dimer Cutoff Safely Excluded DVT
Marc Carrier, Professor at Ottawa Hospital Research Institute, shared a post on LinkedIn:
“New publication in JAMA
Age-adjusted D-dimer can safely rule out suspected DVT
A large multinational prospective management study (n = 3,205 outpatients) provides strong evidence that age-adjusted D-dimer thresholds are not only valid for PE, but also for suspected lower-limb DVT!
Key findings
Using an age-adjusted D-dimer cutoff (age × 10 µg/L for patients ≥50 years) safely excluded DVT
No venous thromboembolic events at 3 months among patients with D-dimer levels between 500 µg/L and their age-adjusted cutoff
+7.4% absolute increase in the proportion of patients in whom DVT could be ruled out without imaging
Reduces unnecessary compression ultrasonography, same safety.
Congratulations to Drs. Grégoire LE GAL, Marc Righini, Helia Robert-Ebadi and the whole team for this important contribution.”
