Anticoagulation prior to direct current cardioversion (DCCV) is mandatory to reduce the risk of thromboembolism. We examined the impact of the use of dabigatran as an alternative to warfarin on the efficiency of an outpatient DCCV service. A total of 242 DCCVs performed on 193 patients over a 36-month period were analysed. Patients were divided into two cohorts; cohort A included cases in the 22-month period before the introduction of dabigatran and cohort B included cases in the 14-month period after the introduction of dabigatran. All patients in cohort A received warfarin. In cohort B, 48.4% received dabigatran. A larger number of patients from cohort A were rescheduled due to subtherapeutic international normalised ratios (INRs) compared with cohort B (42.1% vs. 15.6%, p<0.001). Those who received dabigatran had significantly lower rates of rescheduling compared with those who received warfarin (9.7% vs. 34.4%, p<0.001). The length of time between initial assessment and DCCV was 24 days shorter in cohort B than cohort A (p<0.001) and 22 days shorter with those who took dabigatran than warfarin (p=0.0015). Outcomes in achieving and maintaining sinus rhythm were comparable in both cohorts and anticoagulants (all p>0.05). This study demonstrates that the use of dabigatran can improve the efficiency of an elective DCCV service
