Implication

Low OAC use in high-risk AF signals care gaps; hypothesis-generating for barriers and implementation strategies in public systems.

Key Points

To assess the prevalence of oral anticoagulation therapy and identify factors associated with its prescription in patients with atrial fibrillation treated within a public health system.
Conducted a cross-sectional study evaluating N=162 consecutive patients with electrocardiogram-documented atrial fibrillation between September 2011 and March 2012 at a public university hospital.
Assessed thromboembolic and bleeding risks using CHADS2 and CHA2DS2-VASc scores, alongside tracking medication use and the reviewing physician's specialty.
Only 37.6% of patients classified as high risk by CHADS2 and 35.5% by CHA2DS2-VASc were receiving oral anticoagulation therapy.
Just 50.6% of patients were aware of their atrial fibrillation diagnosis despite high rates of hypertension (90.1%), heart failure (53.4%), and prior stroke (38.9%).
A presumptive diagnosis of heart failure and electrocardiogram review by a cardiologist were the only independent predictors of anticoagulant use.

Structured PICO

What is the prevalence of oral anticoagulation therapy use among patients with atrial fibrillation?

Population

162 consecutive patients with atrial fibrillation documented by an electrocardiogram at a university hospital of the Public Health System, mean age 68.9 years, 56% men.

Intervention

Oral anticoagulation therapy

Outcome

Prevalence of oral anticoagulation therapy use

There is a significantly low prevalence of guideline-indicated oral anticoagulation use among high-risk atrial fibrillation patients in the public health system.
