The challenge

Patients are unaware of their carotid artery disease until they experience a major cerebrovascular event, such as a stroke.

The solution

Screen for carotid calcification on medical imaging and navigate undiagnosed, high-risk patients to the appropriate healthcare professional.
Carotid calcification on non-contrast CT

How does it work?

Bunkerhill’s incidental carotid calcification algorithm runs automatically in the background of all non-contrast head/neck CTs. When the algorithm finds a patient with meaningful carotid calcification, Bunkerhill’s software performs an automatic chart review to determine whether the patient is unaware of their cardiovascular disease and suitable for follow-up (e.g., no end-of-life diseases). If the patient passes through that automatic chart review, Bunkerhill automatically notifies the patient, their PCP, and the appropriate specialist for review.

Why does it matter?

Impact carotid duplex ultrasound screening rates.
Patients with meaningful carotid calcification may undergo carotid duplex ultrasound to further evaluate potential presence and severity of stenosis
Prescribe statins to at-risk patients.
After confirming presence and severity of carotid stenosis, physicians may choose to prescribe statins to slow progression of atherosclerosis and reduce stroke risk.
Impact carotid endarterectomy rates.
Patients who are found to have more severe carotid stenosis may undergo carotid endarterectomy to restore normal blood flow and reduce risk of stroke.
