In a large primary care data set, the CHA(2)DS(2)-VASc score leads to an almost universal recommendation for anticoagulation treatment in those aged >= 65 years with atrial fibrillation
European journal of cardiovascular nursing(2023)
Abstract
From 2012 to 2016, the oral anticoagulant (OAC) treatment determination for atrial fibrillation (AF) patients moved from the CHADS(2) score to the CHA(2)DS(2)-VASc score. A data set collated during previous studies (2011-19) with de-identified data extracted from clinical records at a single time-point for active adult patients (n= 285 635; 8294 with AF) attending 164 general practices in Australia was analysed. The CHA(2)DS(2)-VASc threshold (score >= 2 men/>= 3 women) captured a significantly higher proportion than CHADS(2)>= 2 (all ages: 85 vs. 68%, P< 0.0001; >= 65 years: 96 vs. 76%, P< 0.0001). The change from CHADS(2) to CHA(2)DS(2)-VASc resulted in a significantly higher proportion of AF patients being recommended OAC, driven by the revised scoring for age.
