Welcome to the QDiabetes®(Amputation and blindness) risk calculator

Welcome to the QDiabetes®(Amputation and blindness) Web Calculator. You can use this calculator to work out your risk of developing Amputation and blindness by answering some simple questions.

The QDiabetes®(Amputation and blindness) algorithms have been developed by Julia Hippisley-Cox and Carol Coupland 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.

QDiabetes®(Amputation and blindness) 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.

The science underpinning the new QDiabetes®(Amputation and blindness) equations will be published in due course.
