Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The proportion of time spent in the therapeutic INR range, 2.0 to 3.0; all INRs recorded by the anticoagulation clinic within the first 12 months will be recorded (this will vary for each patient). | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Patients' knowledge and perceptions of AF, questionnaire administered at baseline (time 0), 1, 2, 6, and 12 months 2. Patients' beliefs about their medication, before and after the intervention, questionnaire administered at baseline (time 0), 1, 2, 6, and 12 months 3. The relationship between INR control and patients' experiences of warfarin treatment, the persistence of warfarin therapy, and the incidence of minor and major bleeding, stroke, and thromboembolic events (performed using ancillary analyses, given that the trial is not powered to detect these differences). The number of strokes, bleeding and thromboembolic events will be determined from the computerised clinical information system at the hospital, assessed at 1, 2, 6 and 12 months. 4. A health-economic analysis of the resource utilisation in providing an intensive educational intervention, undertaken at the end of the trial | — |
