Mean of Perception of Anticoagulant Treatment Questionnaire 2 (PACT-Q2) Scores at Second Assessment Compared to Baseline Assessment
Tijdsspanne: When planned to be switched from VKA to Pradaxa® (At baseline, Visit 1), 7 to 124 days after starting treatment with Pradaxa® (initiation period, Visit 2)
|
The PACT-Q is self-administered quest.
which was developed as means to investigate patients' satisfaction with anticoagulant treatment & treatment convenience in patients with deep venous thrombosis (DVT), pulmonary embolism (PE) or atrial fibrillation (AF).
PACT-Q2 quest. is made up of two domains: (1) Convenience (13 items): This domain is calculated by adding inverted scores (6-item score) for each of the 13 items in question & converting to a scale from 0 to 100.
(2) Satisfaction with the anticoagulant treatment (7 items): This domain is calculated by adding scores for each of the 7 items in question & converting to a scale from 0 to 100.
The missing items have been replaced by the mean of non-missing items of the dimension (if 50% of items were completed, non-missing), in order to calculate domains score.
The higher the score, the higher the convenience/satisfaction.
The two domain scores are presented for Baseline, Visit 2 (second assessment) as mean & standard deviation (SD).

Tijdsspanne |
---|---|---|
Patient Characteristics at Baseline - CHA2DS2-VASc Stroke Risk Score and HAS-BLED Bleeding Risk Score
Tijdsspanne: Baseline
|
CHA2DS2-VASc stroke risk score is calculated based on following conditions: Congestive heart failure/left ventricular dysfunction, Hypertension, Age (≥ 75), Diabetes Mellitus,Stroke/Transient Ischaemic Attack (TIA)/thromboembolism,Vascular disease (history of myocardial infarction, peripheral artery disease or aortic plaque) ,Age 65-74, Sex category.
HAS-BLED bleeding risk score is calculated based on following conditions: Uncontrolled hypertension with Systolic Blood pressure (SBP) ≥ 160 mmHg,Kidney failure,liver failure,History of stroke,History of bleeding, anaemia or predisposition to bleeding,Unstable/high or poor international normalized ratio (INR) (<60% of time within therapeutic range),Elderly (>65 years),Medications that affect haemostasis,Consumptions of ≥8 alcoholic drinks per week.CHA2DS2-VASc stroke risk score & HAS-BLED bleeding risk score range from 0 to 9 with 0 being outcome with low stroke risk for CHA2DS2-VASc and being with low bleeding risk for HAS-BLED.

Patient Characteristics at Baseline - Categorical Parameters
Tijdsspanne: Baseline
|
Categorical parameters of the patient characteristics at baseline included age, Risk factors associated with stroke and/or haemorrhage in the medical history (MH), co-morbidities (CoMo), concomitant medication (CM) and dosing of Pradaxa® (DoP). Haemorrhagic risk (HAS-BLED) is categorized as Low risk (score 0), Moderate risk (score 1-2) and High Risk (score ≥3). Thromboembolic risk (CHA2DS2-VASc) is categorized as Low risk (score 0 in male and 1 in female), Moderate risk (score 1 in male and 2 in female) and High Risk (score ≥2 in male and ≥3 in female). Stages of kidney disease are categorized based on Cockcroft-Gault review as below: No kidney failure (> 80 ml/min), Mild kidney failure (50-80 ml/min), Moderate kidney failure (30-49 ml/min), Severe kidney failure (15-29 ml/min) and End-stage kidney failure/dialysis (< 15 ml/min). |
