Welcome to the QIntervention® website

QIntervention® enables you to work out your risk of diabetes, heart disease, or stroke over the next 10 years and show you how that risk could change with interventions such as stopping smoking, losing weight, lowering your blood pressure or taking cholesterol lowering medication. It also shows unintended effects of statins.

The QRISK®2 calculates your risk of cardiovascular disease (which is a heart attack, stroke or 'mini' stroke) and the QDiabetes® algorithm calculates your risk of Type 2 diabetes. Both algorithms have been developed by academic and doctors working in the NHS and are 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. The scores are intended for use in the UK. This site uses the latest 2017 updates to the QRISK®2 and QDiabetes® algorithms.

QRISK®2 is now included in the Department of Health's Standard Operating procedures for Vascular Screening and the national GP contract (QOF), and QDiabetes® has been validated for clinical use, and appears in the NICE guidlines. All medical decisions need to be taken by a patient in consultation with their doctor. Neither ClinRisk Ltd. nor the algorithm's developers accept any responsibility for clinical use or misuse of this calculator.

QDiabetes® was formally known as QDScore®. We like the new name better.
