Quarter 2 2025/26 (July to September 2025)
1 Background
Healthcare associated venous thromboembolism (VTE), commonly known as blood clots, is a significant international patient safety issue. The first step in preventing death and disability from VTE is to identify those at risk so that preventative treatments (prophylaxis) can be given. This data collection quantifies the numbers of hospital admissions (aged 16 and over at the time of admission) who are being risk assessed for VTE to identify those who should be given appropriate prophylaxis based on guidance from the National Institute for Health and Care Excellence (NICE). Such measures have the potential to save many lives each year.
This data collection is intended to embed VTE risk assessment across the NHS and will be critical in evaluating the impact of the National VTE Prevention Programme on improving health outcomes for patients. The VTE risk assessment is a former national CQUIN indicator and is a National Quality Requirement in the NHS Standard Contract for 2025/26. It sets an operational standard of 95% of patients aged 16 and over being risk assessed for VTE on admission each month. Prior to April 2019 the operational standard related to adult patients aged 18 and over.
The data collection asks for the following information:
- number of admitted patients (aged 16 and over at the time of admission) in the month who have been risk assessed for VTE within 14 hours of admission to hospital using the criteria in the NICE guidance.
- total number of admitted patients (aged 16 and over at the time of admission) in the month.
The percentage of admitted patients (aged 16 and over at the time of admission) in the month who have been risk assessed for VTE on admission is automatically calculated from items (1) and (2).
All providers of NHS-funded acute care (that is, NHS trusts and foundation trusts and independent sector providers of acute NHS services) must complete this data collection. Providers of non-acute health services only are not asked to complete this data collection, although they should be aware that all patients should be protected from unnecessary risk of VTE.
For the purposes of this collection, risk assessment should be completed on admitted patients within 14 hours of admission; NICE guidelines state that where required, pharmacological thromboprophylaxis should be started within 14 hours of admission, therefore risk assessment should be completed prior to this, unless otherwise stated in the population-specific recommendations.
This data collection is a census of all patients – it is not appropriate to use sampling methodologies to produce estimates.

3 Summary of the data collection
The key results for the data collected on the number and percentage of VTE risk assessments on admitted patients aged 16 and over to NHS-funded acute care (NHS trusts, NHS foundation trusts and independent sector providers) in quarter 2 (Q2) 2025/26 (July to September 2025) are:
- the percentage of admitted patients risk assessed for VTE in England was 91%. Of the 3.6 million admitted patients for whom data was reported in this collection, 3.3 million were risk assessed for VTE on admission.
- the percentage of admitted patients risk assessed for VTE was 91% for NHS acute care providers and 97% for independent sector providers. NHS acute care providers carry out 96% of all VTE risk assessments.
- the percentage of admitted patients risk assessed for VTE for each region was: East of England 93%, London 93%, Midlands 92%, North East and Yorkshire 89%, North West 90%, South East 93% and South West 89%.
- 26% of integrated care boards (ICBs) (11 of the 42 ICBs) carried out a VTE risk assessment for 95% or more of their admissions (the NHS Standard Contract operational standard).

4.7 Number of valid data returns
- the total number of valid data returns submitted by all providers of NHS-funded acute care in each month of Quarter 2 2025/26 (July to September 2025) was 284.
- the number of valid NHS acute care providers submitting a data return in each month of Quarter 2 2025/26 (July to September 2025) was 122.

5 Data quality
5.1 General
- The data collection is mandatory and risk assessments should be completed on admitted patients within 14 hours of admission. It is a requirement to report on admitted patients aged 16 and over and providers are required to submit information based on a census of patients. The following are excluded from the data:
- providers that submit data with risk assessments completed after 14 hours of admission.
- providers that use different age criteria.
- providers that submit data based on a sample or audit of patients.
- providers that did not have any admissions in a particular month.
- children’s hospitals: Alder Hey Children’s NHS foundation trust (RBS), Great Ormond Street Hospital for Children NHS foundation trust (RP4) and Sheffield Children’s NHS foundation trust (RCU).
5.2 Sample, audit or partially submitted data
The following providers that submit data based on sample or audit of patients are not included in the figures:
- Northampton General Hospital NHS Trust (RNS) submission is calculated from a VTE sample audit. The sample percentage of admitted patients risk-assessed for VTE was 85%. The provider is working towards providing data for all patients admitted once they have implemented an EPMA system later this year.
- Kettering General Hospital NHS Foundation Trust (RNQ) VTE risk assessment process is currently paper based so is submitting data based on a sample of patients. The sample percentage of admitted patients risk-assessed for VTE was 85%. The provider is working towards providing data for all patients admitted once their process is digital.
- University Hospitals of North Midlands NHS Trust (RJE) VTE risk assessment process is based on a sample of patients. The percentage of admitted patients risk-assessed for VTE was 87%. The provider is working towards providing data for all patients admitted once their process is digital.
5.3 Providers preparing to submit
The following providers are in the process of preparing to submit:
- North Cumbria Integrated Care NHS Foundation Trust (RNN) are working towards providing data for all patients admitted once they have implemented a new EPR in early 2026.
- The McIndoe Centre (NXM04). Date to be confirmed.
- Mid Cheshire Hospitals NHS Foundation Trust (RBT) have recently implemented an EPR system and will submit Q2 2025/26 data as part of the revised publication.
- East Suffolk and North Essex NHS Foundation Trust (RDE) VTE risk assessment process was paper based for the reporting period and thus unable to provide risk assessed admission data on all admissions. The provider is working towards providing data for all patients after implementation of a new EPR in October 2025.
- Northern Care Alliance NHS Foundation Trust (RM3). Date to be confirmed.
- Manchester University NHS Foundation Trust (R0A) will submit Q2 2025/26 data as part of the revised publication.
5.4 Zero admissions
- Nuffield Health, Ipswich Hospital (NT222) submitted zero admissions for each month in the submitting period.
- Edgbaston Hospital (NT445) submitted zero admissions for each month in the submitting period.
5.5 No submissions received
The following providers did not submit data for this publication:
- Nuffield Health, Cheltenham Hospital (NT211).
- Buckinghamshire Healthcare NHS Trust (RXQ) were unable to submit VTE data whilst they address a data quality issue following a change in system.
5.6 Quality assurance
Data quality assurance focuses on identifying missing data, data errors (for example the numerator should not be greater than the denominator) and data consistency over time. Any issues identified are discussed with providers and they are given the opportunity to clarify or resubmit their data within the quality assurance period.
6 Timings and publication
Providers must collect data and submit it to the Strategic Data Collection Service run by NHS England. The deadline is the last working day of the month following the quarter end.
Data are submitted and published according to the timings below:
| Timing | Process |
|---|---|
| Month A (for example June) | Data are collected from patients in each provider for the quarter |
| Month B (for example July) | Providers submit their data quarterly for the previous quarter with a deadline of the last working day of the month following the end of that quarter (for example Q1 data is submitted towards the end of July) |
| Month C (for example August) | Data is quality assured |
| Month D (for example September) | Data for the quarter is published on the NHS England website at the beginning of month D (for example Q1 data in early September) |
7 Guidance
Guidance on the data collection is given in the 2025/26 NHS Standard Contract and can be found at: https://www.england.nhs.uk/publication/nhs-standard-contract-2025-26-technical-guidance/
