ARKA Clinical Decision Support is designed to meet all four criteria for Non-Device CDS under FD&C Act §520(o)(1)(E) and FDA's January 2026 final guidance on Clinical Decision Support Software. Recommendations support, not replace, the clinician's judgment. Every recommendation is anchored in a published guideline or peer-reviewed source, with the basis available for independent review. CLIN emphasizes imaging appropriateness at order entry.
This recommendation is intended to support, not replace, clinical judgment. It is generated by ARKA, software designed to meet the four criteria for Non-Device Clinical Decision Support under FD&C Act §520(o)(1)(E) and FDA's final guidance on Clinical Decision Support Software (January 2026). The clinician is responsible for the final decision.
AIIE Evidence
Low-probability + negative D-dimer rules out DVT without imaging; everyone else gets compression Doppler ultrasound.
Suspected lower-extremity DVT follows a probability-based pathway: Wells scoring, D-dimer to rule out in low-probability patients, and compression ultrasound with Doppler as the definitive imaging study for the rest.
