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.
Official statistics are produced impartially and free from political influence.
