VTE Risk Assessment 2016/17

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 in 2016/17 (April 2016 to March 2017).
Note: NHS England changed the frequency of publication from monthly to quarterly with effect from April 2015.
(Providers are still required to collect data on VTE risk assessments monthly; however, they will not need to submit all three months data until the end of the quarter).


The data collection was first made mandatory from June 2010, and data have 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.


New nationally-mandated Quality Requirements, with associated financial consequences, were introduced in relation to VTE assessment (previously a national CQUIN indicator) in the 2014/15 NHS Standard Contract. Technical guidance can be found in the link and documents below:
