Outcome Measures

Primary Outcomes (2)

  • Mean Perception of Anticoagulant Treatment Questionnaire 2 (PACT-Q2) Scores, for Patients in Cohort A, at Second and Last Assessment Compared to Baseline Assessment

    The PACT-Q was a self-administered questionnaire which was developed as a means to investigate patients´ satisfaction with anticoagulant treatment and treatment convenience in patients with deep venous thrombosis (DVT), pulmonary embolism (PE) or atrial fibrillation (AF). The PACT-Q2 was composed of three dimensions covering: convenience (11 items), burden of disease and treatment (2 items), and anticoagulant treatment satisfaction (7 items). Items for convenience and for burden of disease and treatment were reversed(reversed score = 6 - item score), added together and rescaled on a 0-100 scale to obtain the convenience dimension score (CDS). Items for anticoagulant treatment satisfaction were summed and rescaled on a 0-100 scale to determine the satisfaction dimension score (SDS). High scores were more favorable. The two dimension scores were presented for Baseline, Visit 2 (second assessment) and Visit 3 (last assessment) as mean and standard deviation (SD).

    Baseline, Visit 2 (30-45 days after initiation on Pradaxa®), Visit 3 (150-210 days after initiation on Pradaxa®).

  • Mean PACT-Q2 Scores, for Patients in Cohort B, at Second and Last Assessment Compared Between Treatment Groups

    The PACT-Q2 was composed of three dimensions covering: convenience (11 items), burden of disease and treatment (2 items), and anticoagulant treatment satisfaction (7 items). The PACT-Q2 was to be administered to patients once treatment was ongoing. Items for convenience and for burden of disease and treatment were reversed (reversed score = 6 - item score), added together and rescaled on a 0-100 scale to obtain the convenience dimension score. Items for anticoagulant treatment satisfaction were summed and rescaled on a 0-100 scale to determine the satisfaction dimension score. High scores were more favorable. The two dimension scores were presented for Visit 2 (second assessment) and Visit 3 (last assessment) as mean and standard deviation (SD). Propensity score matching (PSM) method was used to identify matched Pradaxa® and VKA patients. Only the matched patients in each treatment group was summarized and used for comparison.

    Visit 2 (30-45 days after initiation on Pradaxa® or VKA) and Visit 3 (150-210 days after initiation on Pradaxa® or VKA).

Secondary Outcomes (2)

  • Mean PACT-Q2 Scores, for Patients in Cohort A, at Last Assessment Compared to Second Assessment

    Visit 2 (30-45 days after initiation on Pradaxa®) and Visit 3 (150-210 days after initiation on Pradaxa®).

Patients 20 years of age or older with a diagnosis of non-valvular atrial fibrillation (NVAF).

You may qualify if:

  • Cohort A (patients switched from VKA to Pradaxa)
  • Written informed consent prior to participation.
  • Female or male patients ≥ 20 years of age with a diagnosis of non-valvular atrial fibrillation (NVAF).
  • At least 3 months of continuous VKA treatment for stroke prevention prior to baseline assessment.

  • OR Cohort B (patients newly initiated Pradaxa or VKA)
  • Written informed consent prior to participation.
  • Female or male patients ≥ 20 years of age, newly diagnosed with NVAF, and no previous treatment for stroke prevention (no use of any OAC within 1 year prior to enrolment).
