Atrial fibrillation (AF)

Project uncovers how to prevent 73 strokes and save 95,608 in South London

In 2011, the SLCSN worked with GPs in Sutton and Merton to optimise treatment of AF. This work followed and built upon the work of the AF National Priority Project in 2010.

GP practices were provided specialist support from an arrhythmia nurse to find whether such support would increase the numbers of patients with atrial fibrillation at risk of stroke (that is, CHADS2 > 1) being prescribed an oral anticoagulant to reduce this risk.


  • The arrhythmia nurse specialist from a local hospital provided education and support to practices, fostering closer links between primary and secondary care.
  • Improvements in numbers of high-risk patients being converted to warfarin were higher than the national average.
  • Strokes prevented and money saved contributed to QIPP plans for South London.
