Primary | Mean Perception of Anticoagulant Treatment Questionnaire, Part 2 (PACT-Q2) Scores, for Patients in Cohort A, at Second Assessment Compared to Baseline Assessment | Mean Perception of Anticoagulant treatment Questionnaire, part 2 (PACT-Q2) scores, for patients in cohort A, at second assessment compared to baseline assessment. The PACT-Q2 is composed of 3 dimensions covering: convenience (11 items), burden of disease & treatment (2 items), & anticoagulant treatment satisfaction (7 items). In this outcome the mean convenience & satisfaction dimension scores of PACT-Q2 at second assessment (Visit 2) were compared with baseline assessment (Visit 1). Within the PACT-Q2, items for convenience & for burden of disease and treatment were reversed (reversed score = 6 - item score), added together & rescaled on a 0-100 scale to obtain the convenience dimension score. Items for anticoagulant treatment satisfaction were summed & rescaled on 0-100 scale to determine satisfaction score. High scores are more favorable. PACT-Q2 which were completed more than 1 day after discontinuation of treatment or using incorrect procedure were excluded from analysis. |

Primary | Mean PACT-Q2 Scores, for Patients in Cohort A, at Last Assessment Compared to Baseline Assessment | Mean PACT-Q2 scores, for patients in cohort A, at last assessment compared to baseline assessment. The mean convenience and satisfaction dimension scores of PACT-Q2 at the last assessment (Visit 3) were compared with the baseline assessment (Visit 1). Within the PACT-Q2, 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 score. High scores are more favorable. PACT-Q2 which were completed more than 1 day after discontinuation of treatment or using incorrect procedure were excluded from the analysis. |
Visit 1 (Baseline) and last assessment Visit 3 (125-365 days after initiation on Pradaxa or VKA) | |
Primary | Mean PACT-Q2 Scores, for Patients in Cohort B, at Second Assessment Compared Between Treatment Groups | Mean PACT-Q2 scores, for patients in cohort B, at second assessment compared between treatment groups. Convenience dimension score and satisfaction dimension score of PACT-Q2 both range from 0 to 100 with high scores indicate better outcome. Mean PACT-Q2 scores, for patients in Cohort B, were compared between matched Pradaxa® and VKA patients at the second assessment. The mean convenience and satisfaction scores of PACT-Q2 were compared between matched Pradaxa® and VKA patients. Pradaxa® and VKA patients were matched based on propensity scores using a variable ratio, parallel, balanced 2:1, nearest neighbour matching algorithm with a caliper width of 0.05 and without replacement. PACT-Q2 which were completed more than 1 day after discontinuation of treatment or using incorrect procedure were excluded from the analysis. |

Secondary | Mean PACT-Q2 Scores, for Patients in Cohort A, at Last Assessment Compared to Second Assessment | Mean PACT-Q2 scores, for patients in cohort A, at last assessment compared to second assessment. The PACT-Q2 is composed of 3 dimensions covering: convenience (11 items), burden of disease and treatment (2 items), and anticoagulant treatment satisfaction (7 items). The mean convenience and satisfaction dimension scores of PACT-Q2 at the last assessment (Visit 3)were compared with the second assessment (Visit 2). Within the PACT-Q2, 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 score. |
Second assessment - Visit 2 (7-124 days after initiation on Pradaxa or VKA) and last assessment - Visit 3 (125-365 days after initiation on Pradaxa or VKA) | |
Secondary | Description of Perception of Anticoagulant Treatment Questionnaire, Part 1 (PACT-Q1) Items at Baseline for Cohort B | For Cohort B, scores of PACT-Q1 at baseline were summarised descriptively. The PACT-Q1 is composed of a single dimension (7 items) covering the expectations of patients regarding their anticoagulant treatment and is to be administered before treatment initiation.
