Predicting the risk of injurious falls in older people with atrial fibrillation


30 Second Summary

Atrial fibrillation (AF) increases stroke risk, and anticoagulation reduces this risk but can cause bleeding. Despite guidelines, many clinicians avoid prescribing anticoagulants to those at risk of falls. This project explores using machine learning to predict injurious falls in older AF patients and aims to develop a tool to personalize anticoagulant treatment based on falls risk.

Atrial fibrillation (AF) is a common cardiac arrhythmia which increases the risk of stroke.

Anticoagulation is very effective in reducing stroke risk but can increase the risk of bleeding, a much feared consequence of anticoagulation is bleeding on the brain. National and international guidance states that anticoagulation should not be withheld because of falls as the benefits still outweigh the risks but many clinicians choose not to prescribe these medications to people who fall or those at risk of falls because they don’t believe the evidence supports this recommendation.

The initial stage aims of this project is to explore if machine learning techniques can be used to develop a model that can predict injurious falls in older people with AF and determine what features are important.

The longer term aim of this project is to ascertain whether a tool could be developed to personalise anticoagulant treatment based on falls risk to help clinicians and patients make more informed treatment decisions.
