Incidence and Risk Factors of Venous Thrombosis of the Lower Limbs After Hospitalization in Medical Patients at Risk

Study Overview
=================
Brief Summary
-----------------
In Tunisia, the available data are limited regarding the incidence of venous thrombosis of the lower limbs (TVMI) post-hospitalization, whether symptomatic or subclinical. The thromboprophylactic strategy will certainly depend on the incidence of this complication and its severity. In this study, we performed a systematic screening for TVMI in a well-characterized cohort of patients discharged after hospitalization >48h for an acute medical condition.

Detailed Description
-----------------
This is a prospective follow-up of patients after hospitalization for more than 48 hours 6 weeks after discharge. The study must be approved by the ethics committee and all patients will have given their written informed consent.

Official Title

Patients Hospitalized for More Than 48 Hours, Acute Medical Illness

Eligibility Criteria
-----------------
Inclusion Criteria: patients included adults aged at least 40 years old hospitalized for more than 48 hours for an acute medical illness (i.e. heart failure, active cancer, acute ischemic stroke, infectious diseases, inflammatory disease and respiratory failure acute) patients at risk of MIVT due to moderate or severe immobility, history of thrombophilia (factor C or S deficiency, etc.), body mass index of 30 kg/m2. Exclusion Criteria: hospitalised for less than 48 patients who required intensive care, patients with cognitive impairment, patients admitted for SARS-CoV-2 infection or patients with a hospital stay <2 days, patients with a pre-existing reason for anticoagulation (therapeutic), such as atrial fibrillation or ETD and patients in whom MIVT is discovered on first ultrasound examination upon discharge from hospital.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| presence of any symptoms suggestive of venous or arterial thromboembolic disease | The first contact took place on day 7 after discharge from the hospital and is done by telephone. Patients will be asked about the presence of any symptoms suggestive of venous or arterial thromboembolic disease: angina, dyspnoea, peripheral edema, pain in the lower limbs or any other new symptom | Day7 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| presence of any symptoms suggestive of venous or arterial thromboembolic disease | On D45, the patient will be seen again in the hospital. On the same day, the same symptoms will be sought and a second venous Doppler ultrasound of the lower limbs will be performed. If PE is suspected, a pulmonary CT angiography will also be performed. | day45 |
