The Post-VTE Functional Status Scale for assessment of functional limitations in patients with venous thromboembolism: construct validity and responsiveness in a prospective cohort study

Introduction Venous thromboembolism (VTE) is a common disease with various long-term sequelae such as impaired quality of life and psychosocial consequences. Additionally, a large proportion of patients experience functional limitations after an acute episode of VTE. Recently, the post-VTE functional status (PVFS) scale was proposed to capture these limitations. [1] We performed a prospective cohort study to validate this scale.
