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
EXPEDITE: high clinical suspicion of torsion → immediate urology consult and exploration; Doppler US only when it will not delay detorsion.
Testicular salvage falls steeply after six hours of torsion. High-suspicion presentations (TWIST high score) go directly to surgical exploration; Doppler ultrasound serves intermediate-suspicion cases and must be obtained emergently.
