Travelers' thrombosis--a state of practice in Germany.

Background: Evidence-based guidelines to prevent travelers' thrombosis (TT) are still missing. We wanted to know whether travelers perceive the risk of TT, how they and their physicians cope with this in daily life, and whether recommended thrombosis prophylaxis (TP) was actually performed.

Methods: A standardized questionnaire (Q1) asking for age, gender, travel habits, and the assessment of the risk of TT was given to randomly incoming travelers seeking for travel medicine advice prior to long haul travel.
