AI model could spot hidden blood clot risk in ICU patients
NCT ID NCT07596264
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study used data from over 12,000 ICU patients to create a computer model that can predict which patients are at risk for venous thromboembolism (VTE) – dangerous blood clots. The model was designed to be easy for doctors to understand and use. The goal is to improve prevention and save lives in the ICU.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this model could help doctors identify ICU patients at high risk for blood clots, potentially preventing life-threatening events.
- What could go wrong
- This is a model development study, not a treatment trial. The model needs further testing in real-world settings before it can be widely used.

Who is studied
Patients admitted to ICU were included in the study cohort from January 2022 to October 2025. Inclusion criteria were: (1) age ≥18 years; (2) ICU length of stay ≥48 hours; (3) only the first ICU admission per patient was retained. Exclusion criteria were: (1) VTE diagnosed prior to ICU admission; (2) VTE diagnosed within 24 hours of ICU admission; (3) \>20% missing values in key variables. The final cohort comprised 12,061 patients, of whom 587 (4.9%) developed VTE during ICU hospitalization.
