EU PAS Register NumberEUPAS14786
Official titlePost-Authorisation Safety Study (PASS) of the Utilisation Patterns of Apixaban in Denmark
Study title acronym
Study typeObservational study
Brief description of the studyApixaban (ELIQUIS®) is an orally administered anticoagulant that was approved in the European Union (EU) in May 2011 for the prevention of venous thromboembolic events (VTE) in adults who have undergone elective hip or knee replacement surgery. Subsequently, apixaban received approvals for stroke and systemic embolism (SE) prevention in those with nonvalvular atrial fibrillation (NVAF), and for the treatment and prevention of deep venous thrombosis (DVT) and pulmonary embolism (PE) in adults. This study aims to estimate the proportion of apixaban users in the outpatient settings who receive the drug for the approved indications at the time of the study, and describe the characteristics of the patients who are prescribed apixaban for on-label and off-label indications. These aims will be examined with a descriptive, retrospective, cross-sectional study that uses electronic healthcare data from the Danish national registries. All patients dispensed apixaban as recorded in the Danish Health Services Prescription Database from May 2011 to December 2014 will be included.

15. Data analysis plan
Please provide a brief summary of the analysis method
Data will be collected on apixaban dispensations, prescriber specialty, and patient characteristics such as age, gender, morbidities, concomitant medications, and hospital-based diagnoses and procedures. Patients will be classified as on-label or off-label users if their initial indication has been recorded or can be inferred from the registry data. If an apixaban indication is not present or cannot be inferred from the registries, the patients’ indications will be considered unknown. Information will be drawn from the Danish Civil Registration System (DCRS), Danish National Patient Register (DNPR), and the National Health Service Prescription Database (NHSPD).
