Quarter 3 2025/26 (October to December 2025)

Since the data collection restarted in 2025, we have been working with providers to understand and improve data quality for this collection. Internal analysis comparing reported denominators with unpublished activity data suggested discrepancies in some reported eligible admissions; subsequent work with individual providers has identified issues around:

  • patients not included in submissions when the data collection methodology says to include them, such as maternity patients, day cases, and admissions with length of stay below certain thresholds
  • independent providers including patients who are not NHS‑funded
  • patients cohorted in line with NICE guidelines but not included in the submission
  • submissions based on incomplete, sample, or audit data

We are continuing to work with providers to improve data quality, prioritising those providers reporting the largest discrepancies, and we expect to identify further data quality issues as this work continues. More detail in relation to specific data quality issues identified is available in the ‘Data quality’ section of this report. The latest published quarter provides the most accurate and current position. Every six months the most recent two quarters are revised, ensuring they are updated to reflect the most recent and complete data.

 

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:

  1. 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.
  2. 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 3 (Q3) 2025/26 (October to December 2025) are:

  • the percentage of admitted patients risk assessed for VTE in England was 92%. Of the 3.7 million admitted patients for whom data was reported in this collection, 3.4 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 93% for independent sector providers. NHS acute care providers carry out 97% of all VTE risk assessments.
  • the percentage of admitted patients risk assessed for VTE for each region was: East of England 94%, London 92%, Midlands 91%, North East and Yorkshire 89%, North West 91%, South East 93% and South West 91%.
  • 33% of integrated care boards (ICBs) (14 of the 42 ICBs) carried out a VTE risk assessment for 95% or more of their admissions (the NHS Standard Contract operational standard).

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:

  • Sherwood Forest Hospitals NHS Foundation Trust (RK5) are currently reporting on a proportion of patients. This submission did not include patients admitted for less than 14hrs. The percentage of admitted patients risk-assessed for VTE for this data was 86%. The provider is working towards providing data for all patients admitted once they have agreed a new cohort approach.
  • Royal United Hospitals Bath NHS Foundation Trust (RD1) are currently reporting on a proportion of patients. This submission did not include Maternity admissions or patients admitted for less than 6hrs. The percentage of admitted patients risk-assessed for VTE for this data was 76%. The provider is working towards providing data for all patients admitted once they have agreed a new cohort approach.
  • East and North Hertfordshire Teaching NHS Trust (RWH) are currently reporting on a proportion of patients and for some areas the risk assessment process is currently paper based. The percentage of admitted patients risk-assessed for VTE for this data was 77%. The provider is working towards providing data for all patients admitted once they have implemented an electronic system later this year.
  • 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.
  • Salisbury NHS Foundation Trust (RNZ) are only reporting on a proportion of patients. The percentage of admitted patients risk-assessed for VTE for this data was 41%. The provider is working towards providing data for all patients admitted once they have implemented a new EPR in 2027.
  • 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 82%. The provider is working towards providing data for all patients admitted once they have implemented an EPMA system in June 2026.
  • Medway NHS Foundation Trust (RPA) are currently reporting on a proportion of patients. The percentage of admitted patients risk-assessed for VTE for this data was 96%. The provider is working towards providing data for all patients admitted once they have agreed a new cohort approach.
  • Royal Berkshire NHS Foundation Trust (RHW) reported problems with data collection this quarter and are only reporting on a proportion of patients. They are missing maternity data from November. The percentage of admitted patients risk-assessed for VTE for this data was 97%.
  • 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 88%. 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 March 2026.
  • Royal Cornwall Hospitals NHS Trust (REF) are working towards providing data for all patients admitted once they have implemented a new EPR in early 2026.

5.4 Zero admissions

The following providers submitted zero admissions for each month in the submitting period:

  • Edgbaston Hospital (NT445).

5.5 No submissions received

The following providers did not submit data for this publication:

  • 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/
