Who dies from venous thromboembolism after hospitalisation for other reasons in England?: a national retrospective cohort study
Objectives Venous thromboembolism (VTE) is a major cause of morbidity and mortality globally, with hospital-associated thrombosis (HAT) accounting for at least half of VTE.
