ARA patents AI model to anticipate circulatory shock

Applied Research Associates (ARA) has secured a patent for an AI model designed to identify circulatory shock before its onset. The approach combines historical intensive care patient data with clinical expertise to address limitations in traditional rule-based scoring tools, which offer broad assessments of patient risk.

Circulatory shock is a life-threatening condition encountered in hospital intensive care units and prolonged field care for military combat casualties, with mortality rates reaching 50 to 60 percent. Septic shock, a form of circulatory shock, costs the U.S. health care system $23 billion annually.

Researchers tested the model in the Mayo Clinic’s ICU to evaluate alarm fatigue, patient impact and other considerations identified by clinical users. The patented technology is now used across government and civilian settings, including U.S. ICUs through ARA’s collaboration with Ambient Clinical Analytics.

The work formed part of ARA’s Trauma Triage and Treatment and Training Decision Support (4TDS) project, funded by the Defense Health Agency through the Medical Technology Enterprise Consortium (MTEC).
