Early detection of deep vein thrombosis in critically ill patients
Official title: Diagnosing Deep-vein Thrombosis Early in Critically Ill Patients (DETECT) Trial
Run by King Abdullah International Medical Research Center · NCT05112705 · Data updated 2026-11-12
This study tests if regular ultrasound checks can help find blood clots in critically ill patients to see if it can lower the risk of serious complications and improve survival rates.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are critically ill patients aged 18 and older who are expected to remain in the ICU for more than two days.
✕Probably not a fit
Patients with a recent diagnosis of DVT or PE, those on chronic anticoagulation therapy, or those with conditions preventing adequate ultrasound will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This trial investigates whether regular ultrasound screenings can help detect deep vein thrombosis (DVT) in critically ill patients, potentially reducing the risk of pulmonary embolism (PE) and lowering overall mortality rates within 90 days. Patients admitted to the ICU will be screened for eligibility and randomized to receive either twice-weekly ultrasounds of their lower limbs or standard care. The study aims to determine if proactive monitoring can improve patient outcomes in this high-risk population.
Why it matters
Potential benefit: If successful, this approach could significantly reduce the incidence of pulmonary embolism and improve survival rates among critically ill patients.
How similar studies have gone: Previous studies have shown that early detection of DVT can lead to better outcomes, suggesting this approach may be effective.

Patients with DVT or PE diagnosed within the last year. 2. Patients receiving chronic systemic anticoagulation. 3. Patients who have received up to the time of ICU admission or are receiving therapeutic doses of anticoagulation with UFH, LMWH, or other anticoagulants. 4. Inability or contraindication to obtain adequate ultrasound on the lower extremities (Burns in the lower extremities, lacerations, active skin infection, \& ischemic limb in the legs, large dressings in the thighs that prevent adequate ultrasounds OR amputated foot or leg on one or two sides) 5.
