A questionnaire to assess risk factors, quality of life, and use of health resources in patients with venous disease.

Abstract

The questionnaire was able to pick out recognised risk factors, and is suitable for use in studies of patients with venous disorders. It may also provide information about factors that have not yet been accepted. The case-control study is an appropriate way of assessing not only risk factors, but also signs and symptoms, quality of life, and use of health resources in patients with venous disease.
