Patient information material Not available in web format, please contact Professor Witold Z. Tomkowski (w.tomkowski@igichp.edu.pl) to request a patient information sheet
Target number of participants 3000
Interventions A campaign to raise public awareness of DVT was conducted in an urban population cluster (A) of approximately 100,000 via distribution of brochures four times during a year and publishing posters and newsletter articles.

A comparison urban population cluster (B) of approximately 1,574,000, was not exposed to this campaign.

Patients symptomatic for DVT in both populations were referred by general practitioners for a standardized compression ultrasound (CUS) of the whole leg at no charge to the patient. Reports of positive CUS exams documented by photographs were analyzed by an independent adjudication committee blinded to the population cluster. Cluster A was followed for 8 months after the information campaign ended.
Primary outcome measure(s) Evaluation of the impact of an educational campaign dedicated to thromboembolic complications on increased number of correctly diagnosed DVT
Secondary outcome measure(s) 1. Evaluation of the rate of correctly diagnosed DVT among the general population in Poland
2. Evaluation of the risk factors in patients with confirmed DVT
3. Evaluation of which diagnostic methods are applied to confirm DVT symptoms
