BriefCase-Triage

Aidoc Medical, Ltd.'s BriefCase-Triage is an AI-powered radiological software designed to enhance clinical workflow by rapidly identifying suspected acute rib fractures in CT images. Its methodology involves an artificial intelligence algorithm validated through a multicenter study, demonstrating high accuracy and improved notification times, thereby serving as a triage tool that operates parallel to standard diagnostic interpretation.

Aidoc Medical, Ltd.'s BriefCase-Triage is a radiological computer-aided triage and notification software designed to assist hospital networks and appropriately trained medical specialists. Its primary function is to flag and communicate suspect cases of three or more acute rib fracture pathologies in CT images, utilizing an artificial intelligence algorithm to prioritize workflow. The system provides notifications with compressed preview images, which are explicitly stated as being for informational purposes only and not intended for diagnostic use, ensuring it operates in parallel to the standard of care for image interpretation. The determination of equivalence, allowing its market clearance, was supported by performance data from a retrospective, multicenter study. This study demonstrated that the BriefCase-Triage software met pre-specified accuracy goals for identifying rib fractures, exhibiting high area under the curve (AUC), sensitivity, and specificity. Additionally, the device demonstrated a time-to-notification that was comparable to, and in some instances faster than, its predicate device, thereby contributing to improved workflow efficiency in a clinical setting.

• Q1. How does the AI algorithm specifically identify and count rib fractures, and what are its limitations regarding subtle or atypical fracture patterns?; What is the real-world impact of "improved workflow efficiency" on patient outcomes, and has this been quantified beyond time-to-notification?; Given that notifications are for informational purposes only, what safeguards are in place to prevent over-reliance or misinterpretation by clinicians, especially in high-volume settings?; Were different CT scanner types or image acquisition protocols used in the multicenter study, and how might variations affect the device's performance?; What is the false positive rate, and how frequently does the system flag cases that do not actually have three or more rib fractures, potentially leading to alert fatigue?
