Overview
Assessment of absolute CVD risk based on multiple risk factors is more accurate than that based on individual risk factors due to the cumulative nature of risk effects. Absolute CVD risk assessment combines risk factors to calculate the probability that an individual will develop a cardiovascular event or other vascular disease within a specified time frame, usually 5 years (RACGP 2018). The risk assessment is useful for measuring risk in asymptomatic clients without established CVD (i.e. for primary prevention). Clients aged 45–74 years with established CVD and/or several other conditions who are already clinically determined to be at high risk of a cardiovascular event (NVDPA 2012) have been excluded from the measure as outlined in the PIPQI specification.
Capture of results recorded outside of the general practice setting
Results arising from clinical intervention conducted outside of the service that are known and recorded by the practice are included in the measure. However, sometimes test results recorded elsewhere may not be captured in this report. For example, this might be a result from a specialist service that is not recorded in the clinical information system (CISs) of the client’s usual general practice due to an incompatible CISs between a practice and a specialist service.
Other sources of relevant data
There are other administrative data collections where the relevant data from these client-provider interactions are captured, for example, Medicare Benefits Schedule (MBS) and the National Health Survey (NHS) conducted by the Australian Bureau of Statistics (ABS).
This indicator reports on the proportion of regular clients aged 45 to 74 years without a CVD diagnosis with 4 risk factors (tobacco smoking status, diabetes type or HbA1c result or fasting glucose tests, blood pressure, lipid levels) recorded in their GP record to enable CVD risk assessment.
The QIM proportions summarised by the different extraction tools in use are also shown in the ‘Regional proportions’ bar charts for this measure. This illustrates the differences in how software providers have interpreted the technical specifications and coding of QIMs.
QIM 8: Regional proportions
As of July 2023, nationally, 52.6% of regular clients aged 45 to 74 years without a CVD diagnosis had the necessary risk factors recorded in their GP record to enable CVD risk assessment. This varied from 36.1% to 74.1% across PHNs, and between 41.2% and 56.1% across extraction tools.

This bar chart shows the proportion of regular clients aged 45 to 74 years with the necessary CVD risk factors recorded in their GP record to enable CVD risk assessment, by PHN and extraction tool, for July 2023.
QIM 8: National proportions over time
Nationally, between January 2023 and July 2023, the proportion of regular clients aged 45 to 74 years without a CVD diagnosis who had the necessary risk factors recorded in their GP record to enable CVD risk assessment remained constant at 51.0% and 52.6%, respectively.

QIM 8: National proportions by age and sex
As of July 2023, the proportion of regular clients aged 45 to 74 years without a CVD diagnosis with the necessary risk factors recorded in their GP record to enable CVD risk assessment increased with age and was:
- highest in the 65–74 years age group for both females (58.1%) and males (58.4%)
- lowest in the 45–54 years age group for both females (47.6%) and males (46.6%).

This bar chart shows the proportion of regular clients aged 45 to 74 years with the necessary CVD risk factors recorded in their GP record to enable CVD risk assessment, by age and sex for July 2023
- Data for clients are included if they have record of necessary risk factors (age, sex, tobacco smoking status, diabetes type or HbA1c result or fasting glucose tests, blood pressure, lipid levels) to assess CVD risk assessment.
- Clinical definitions for CVD vary across CISs, as different coding schemes are used. This may lead to some variation in the number of clients who will be picked up by different systems (AIHW 2023f).
- The reference periods for recording the risk factors of this QIM have been interpreted and coded differently by extraction tool providers. The POLAR extraction tool used by 6 PHNs, applied reference period cut-off dates of 24 months for recording systolic blood pressure and 5 years for recording cholesterol/HDL levels, in line with the RACGP Red Book (RACGP 2018). In contrast, the CAT Plus extraction tool used by 25 PHNs and Primary Sense extraction tool used by 2 PHNs, did not apply any reference period cut-off dates for diabetes screening, systolic blood pressure, cholesterol/HDL levels. For this reason, these results should be interpreted with caution when comparing results between extraction tools.
- Eligible clients who do not have a current diagnosis of a cardiovascular condition and have a record of age, sex, tobacco smoking status, systolic blood pressure, diabetes status/diabetes screening test, total cholesterol and HDL cholesterol levels in their GP record are included in the measure.
- Clients are excluded from the measure if they:
- refused measurement,
- have a recorded diagnosis of CVD,
- are regular and without known CVD, but information for ALL risk factors is not recorded.
