Abstract: 

Background: Despite clear evidence for the effectiveness of oral anticoagulation (OA) in patients with atrial fibrillation (AF), there is evidence for the underutilisation of this therapy in the secondary stroke prevention. We therefore investigate the link between the use of OA in stroke patients with AF and favourable clinical outcome following the acute event.

Methods: The study population was determined by identifying the overlap of two different databases: a stroke registry and claims data of a health insurance company. Baseline data originated from the registry; documented dementia and the prescriptions for OA were derived from the insurance database. Patients with AF, minor physical impairment, and evidence of more than 30 days without further hospitalisation within the subsequent 90 days after the acute event were selected for the analysis.

Results: 1828 patients were selected (mean age 77.6 years), 1064 patients (58.2%) were female. 827 patients (45%) received a prescription for OA. The following factors were independently associated with no prescription for oral anticoagulants: increased age (OR: 0.54, CI: 0.46-0.63; P < 0.0001), female sex (OR: 0.77, CI: 0.63-0.94; P < 0.011), worsening disability status at discharge (OR: 0.88, CI: 0.81-0.96; P < 0.006), and documented dementia (OR: 0.54, CI: 0.39-0.73; P < 0.001). Conversely, treatment in a neurological department was associated with prescription for OA (OR: 1.47, CI: 1.19-1.81; P < 0.003).

Conclusions: In more than half of the patients with AF who suffered a stroke OA was not prescribed. The factors associated with reluctance in prescribing anticoagulants are increasing age, female sex, treatment at a non-neurological department, worsening disability, and dementia.
