Welcome to the QThrombosis® risk calculator
Welcome to the QThrombosis® Web Calculator. You can use this calculator to work out your risk of developing venous thromboembolism by answering some simple questions.
It has been designed to assess future risk of thrombosis in patients without symptoms. It is not designed to be used when making a diagnosis of thrombosis.
The QThrombosis® 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.
QThrombosis® 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 QThrombosis® equations has been published in the BMJ.
