Introduction
•
778,973 prescriptions for warfarin in Ireland (2008) Aim of study
Audit to assess standard of care provided to patients as determined by TTR Atrial fibrillationPulmonary embolism / Deep vein thrombosisPost-valve replacement Secondary objective to undertake an economic assessment of the model of AF associated stroke increases progressively with age RR reduction of stroke with warfarin over aspirin 39% Audit standards
North Dublin Population Stroke Study 2010: BCSH recommendation - 60% TTR (+/- 0.5 units target) <25% of those with known AF anticoagulated with 4 weekly testing for those stabilised (Ansell et al) Models of care
Primary care, secondary care, patient self-testing Protocol development and ICGP Ethical Approval (Nov ’09) Time in therapeutic range (TTR) assessment Inclusion of Rosendaal’s method of linear interpolation Complete GP® Rosendaal linear interpolation method or % time spent in range Study Setting

Conclusion
Simple adjustment to software allowed incorporation of TTR AF 61%, DVT/PE 13%, Post-valve replacement 14.5% TTR in re-audit increased to 61% from 54% (12 months) Cost to practice of managing one GMS AF patient on warfarin Time in Therapeutic Range
