April 2016: Statement 4 on mechanical interventions (graduated compression stockings) for people with proximal deep vein thrombosis has been removed. This change has been made because the source guidance for this statement (NICE's guideline on venous thromboembolic diseases: diagnosis, management and thrombophilia testing) was updated in November 2015 and the advice on using compression stockings has changed.
Minor changes since publication
March 2020: Changes have been made to align this quality standard with the updated NICE guideline on venous thromboembolic diseases: diagnosis, management and thrombophilia testing. The source guidance references, data sources and definitions sections have been updated throughout.
