This standard supports the implementation of cardiovascular disease risk assessment using the agreed primary prevention equations.
Improving the accuracy and consistency of cardiovascular disease (CVD) risk assessment and management is an opportunity for significantly improving equity in health outcomes for New Zealanders. We want to see CVD risk being assessed, understood and managed to ensure that morbidity and mortality for key New Zealand population groups continue to improve over time.
HISO 10071:2019 Cardiovascular Disease Risk Assessment Data Standard supports the frontline implementation of two new sex-specific CVD risk equations for primary prevention; for the general population and for patients who have diabetes. It provides a data set specification for the inputs to the calculation, and the algorithms used. The clinical aspects of CVD risk assessment are covered by the following publication: Cardiovascular Disease Risk Assessment and Management for Primary Care.
Risk calculators will need to provide a good user experience for both the patient and the clinician. This includes integration with patient management systems, and consideration being given to health literacy, risk communication and consumer interfaces.
The Ministry is preparing for the implementation of a national risk calculator to ensure all practitioners in New Zealand have access to this functionality. We are on track to deliver the calculator in 2020. We are also in the process of setting up an expert advisory group to provide advice and oversight on sector adoption of the equations, review potential changes to the equations, and oversee updates to the published clinical guidance and data standard.
New Zealand-specific CVD risk equations for other key populations will be available in the future (eg, patients with serious mental illness) which will necessitate an update to the published clinical guidance and data standard.
Test cases and worked examples
We have posted a set of test cases and updated the main document to include worked examples to support implementation of the new sex-specific CVD risk equations for primary prevention. The test cases and worked examples have been developed to assist software suppliers to check the behaviour of their calculators. The set of test cases, although not exhaustive, represents a reasonable clinical range of patient profiles.

We will provide monthly updates on progress to the sector, through clinical groups and networks and posted here.
