Methodology

Value definitions

National value: The total proportion, calculated for England. This value shows us the proportion when we consider all patients registered at GP practices in England, that participate in the CVDPREVENT audit (more than 95% of GP practices in England participate).

System median: The median of the area values that have been calculated for all geographical areas/systems that are of the same type as that chosen in the blue bar. For example, if you have selected a PCN, the system median will be a PCN system median and show the middle value from a list of the PCN area values for the indicator, ordered from smallest to largest.

Area value: The local proportion, calculated for the geographical area/system selected in the blue bar. This value shows us the proportion when we consider just those patients registered at GP practices within the selected area/system, that participate in the CVDPREVENT audit (you can view the participation rate for the chosen area/system in the blue bar).

Population and practice coverage

Population coverage: number of patients from the GP list size of contributing practices as a proportion of the total GP patient registered population for the area.

Practice coverage: calculated from the number of practices for which data has been received as a proportion of practices.

Beta

The CVDPREVENT Data & Improvement Tool is in the ‘beta’ phase of development. This means you’re looking at the first version of the tool, and it being continually tested and improved.

Quintile Highlighting

Quintiles are highlighted to show how the selected area’s value for a particular indicator and inequalities marker compares to the overall data for that area’s system level. For example, values for a CCG will be compared to all available data at CCG level for the same marker split into quintiles.

For some inequalities markers, the data is consistent or the range is small. In these cases, multiple quintiles may be highlighted, as the selected area’s value will fall within multiple system level quintiles.

Reintroduction of CVDP004CKD

The CVDPREVENT indicator CVDP004CKD: Percentage of patients aged 18 and over with GP recorded CKD categories G3a to G5 (previously stage 3 to 5) with a record of a urine albumin:creatinine ratio (or protein:creatinine ratio) test in the preceding 12 months has been re-introduced from the June 2023 update. However, any comparisons with the previous data periods will not be possible and hence, we have removed any previous data points.

Previously published figures are likely to represent an underestimate of the albumin/protein creatinine ratio testing performed on patients with a CKD diagnosis. The CVDPREVENT audit extract was amended to include a more complete record of ACR/PCR testing. This amendment was made in the June 2023 update.

CVDP002AF Removal

The CVDPREVENT indicator CVDP002AF: Percentage of patients aged 18 and over with GP recorded atrial fibrillation and a record of a CHA2DS2-VASc score of 2 or more, who are currently treated with anticoagulation drug therapy has been withheld from the September 2023 data update.

A technical issue was identified in the data collection process which has affected the audit values for this indicator in the September 2023 extract. This does not impact any historical data for this indicator. A resolution to this issue is being pursued and CVDP002AF will be reinstated as soon as possible.

Ambitions

The 3-year ambitions for CVDP001CVKM (SGLT2i treatment for people with CKD, heart failure or type 2 diabetes), CVDP004HF (4 pillars therapy for HFrEF), CVDP007HYP (hypertension treatment to target for people without CVD), CVDP008CHOL (lipid optimisation for people without CVD), CVDP010HYP (blood pressure treatment to target for people with CVD) and CVDP012CHOL (cholesterol optimisation for people with CVD) reference the national ambitions set out in the Cardiovascular disease (CVD) modern service framework (MSF): a cardiovascular-kidney-metabolic approach – the strategic vision and delivery model, NHS England, published 7 July 2026.

Outcomes admissions data for NHS Frimley ICB

The CVDPREVENT indicator CVDP002ADMN: Data on hospital admissions for Frimley ICB has been removed for this period.

Data on hospital admissions outcomes for Frimley ICB has been removed for several time periods. Between July 2022 and March 2023, Frimley Health NHS Foundation Trust were unable to submit data for use in Hospital Episode Statistics (HES), the source for admissions data used in the outcomes analysis. When reviewing initial data, we also observed Frimley ICB as an outlier on these indicators. It is possible that patients from other ICBs were admitted to Frimley NHS Trust and their data affected by this issue, but we understand the effect of this to be minimal and there are no clear impacts on neighbouring ICBs in the outcomes data. We will reinstate data for Frimley ICB as soon as it is possible to do so.
