VTE prediction risk tool at the touch of a finger

GPS CAN now access a new risk prediction tool to calculate the absolute risk of venous thromboembolism (VTE) in patients without prior history of clots.

The QThrombosis algorithm, developed by UK researchers from a large general practice database, and based on clinical variables that the patient is likely to know or which are routinely recorded, quantifies the risk of thrombosis at one and five years.

The variables include age, BMI, smoking status, Townsend deprivation scores and use of drugs, such as antipsychotics, tamoxifen or HRT.

The researchers said the algorithm, derived from nearly 15,000 VTE cases in a patient cohort of 3.5 million people aged 25-84 years, could be integrated into clinical computer systems.

The tool could be useful in identifying patients at increased risk of VTE before hospital admission or long-haul flights – especially when considering medications that might increase VTE risk, or when identifying high
