Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 and older who are referred to the emergency department with suspected deep vein thrombosis.
✕Probably not a fit
Patients currently on anticoagulation therapy for more than 72 hours or with a life expectancy of less than three months may not benefit from this study.

What this trial studies
This clinical trial aims to evaluate the effectiveness of a machine learning algorithm combined with point-of-care D-dimer testing and ultrasound in excluding deep vein thrombosis (DVT) in patients suspected of having the condition. Participants will undergo standard diagnostic procedures, including clinical assessment, D-dimer analysis, and ultrasound, while also receiving additional tests with POC D-dimer and ultrasound performed by emergency department physicians. The study will assess whether the machine learning model can accurately predict DVT exclusion without the need for ultrasound in some cases. The goal is to improve diagnostic efficiency and patient outcomes in DVT management.
Why it matters
Potential benefit: If successful, this approach could lead to faster and more accurate diagnosis of deep vein thrombosis, reducing unnecessary procedures and improving patient care.
How similar studies have gone: While the use of machine learning in medical diagnostics is a growing field, this specific approach to DVT detection is relatively novel and has not been extensively tested in prior studies.
