Venous Thromboembolism (VTE) Risk Assessment

This section of the website provides information on the number and proportion of admitted adult patients in England who have been risk assessed for VTE.

Note: From November 2013 onwards, data will be made public on the NHS England website and in UNIFY on the same day and time so that these statistics are equally available to all users. This is in compliance with the UK Statistics Authority’s Code of Practice for Official Statistics (January 2009).


The data collection was first made mandatory from June 2010, and data has been published quarterly from the first full quarters data (July-September 2010).

The data collection asks for three items of information:
1. Number of adults admitted as inpatients in the month who have been risk assessed for VTE on admission to hospital using the criteria in the National VTE Risk Assessment Tool
2. Total number of adult inpatients admitted in the month
3. Calculated from (1) and (2), the percentage of adult hospital admissions, admitted within the month assessed for risk of VTE on admission

Trusts are required to upload their data on VTE risk assessment onto Unify2 and signed off no later than 20 working days after the month end.
