Welcome to the QRISK®3 risk calculator

This demonstrator is intended for reference purposes only, and as a guide.

Note that this web site is not a class 1 medical device, and therefore is not intended for clinical use.

For health professionals using clinical management systems, we recommend the use of the EP-QRISK3 Engine integrated with a health management system.

Unlike this web site, the EP-QRISK3 Engine is registered as a Class I medical device which is a prerequisite for the use of decision support software for patient care, and is available in a variety of forms for system suppliers to use. See suppliersfor more information on accredited suppliers.

This site uses the QRISK3 calculator to present and an approximation of a person's risk of developing a heart attack or stroke over the next 10 years, ( assuming they do not already have cardiovascular disease and are not on statins) . A score is produced as described in this academic paper:

It presents the average risk of people with the same risk factors as those entered for that person.

The algorithm has been developed by doctors and academics working in the UK National Health Service and is based on routinely collected data from many thousands of GPs across the country who have freely contributed data to the QResearch database for medical research.

It has been developed for the UK population, and is intended for use in the UK. All medical decisions need to be taken by a patient in consultation with their doctor. The authors and the sponsors accept no responsibility for clinical use or misuse of this score.

Has QRISK®3 calculator been validated?

Yes. Validatation of the underlying algorithm is described in the academic paper linked above.

Validation and assurance of the EP- QRISK3 Engine has been done and is registered as a class 1 medical device in the UK.
