“…Other factors that could have an influence in the low prescription of anticoagulation in our study are physicians' distrust in the validity of clinical trials that support these CCSs, 30 the uncertainty about whether the CCSs' benefits are applicable to clinical practice, 31 or their reticence to initiate anticoagulation for older patients, 16,27,30,32 despite the available evidence. 33 In addition to this, in some cases, the emergency physicians could be following the recommendations of local clinical practice guides, and the rate of anticoagulation would vary as much as 13% to 100%, depending on the guideline used. 34 Finally, the type of NVAF had an impact on the prescription pattern: anticoagulation was more frequently indicated in patients with paroxysmal NVAF than in those with persistent or permanent NVAF.…”
