Mean Perception of Anticoagulant Treatment Questionnaire 2 (PACT-Q2) Scores, for Patients in Cohort A, at Second and Last Assessment Compared to Baseline Assessment Primary · Baseline, Visit 2 (30-45 days after initiation on Pradaxa®), Visit 3 (150-210 days after initiation on Pradaxa®).

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 scal

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

Description of PACT-Q1 Items for Patients in Cohort B at Baseline Secondary · Baseline

The PACT-Q1 was composed of a single dimension (7 items), covering the expectations of patients regarding their anticoagulant treatment, and was to be administered before treatment initiation. The 7 items were: Q1: How confident are you that your anticoagulant treatment will prevent blood clots? Q2: Do you expect that your anticoagulant treatment will relieve some of the symptoms you experience? Q3: Do you expect that your anticoagulant treatment will cause side effects such as minor bruises or bleeding? Q4: How important is it for you to have an anticoagulant treatment that is easy to take?
