What this trial studies

This observational study aims to assess the incidence of venous thrombosis of the lower limbs in patients who have been hospitalized for more than 48 hours due to acute medical illnesses. It involves a systematic screening of patients six weeks after their discharge to identify both symptomatic and subclinical cases of thrombosis. The study is designed to gather data that could inform thromboprophylactic strategies based on the observed incidence and severity of this complication. Ethical approval has been obtained, and all participants will provide informed consent.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40 and older who have been hospitalized for more than 48 hours due to acute medical conditions and are at risk for venous thrombosis.

Not a fit: Patients hospitalized for less than 48 hours or those with pre-existing conditions requiring anticoagulation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prevention strategies for venous thrombosis in at-risk hospitalized patients.

How similar studies have performed: Other studies have shown varying success in assessing venous thrombosis incidence in similar patient populations, but this specific approach in Tunisia is relatively novel.
