Tiltaksbeskrivelse
Tidsramme
CHA2-DS2-VASc-poengsum ved baseline
Tidsramme: Baseline (fra retrospektive data hentet i studien)
CHA2DS2-VASc skåringsskala ble brukt for å estimere risikoen for hjerneslag og systemiske emboli hos deltakere med NVAF. CHA2DS2-VASc-score ble beregnet basert på 8 risikofaktorer (alder 65-74 år, alder >=75 år, kjønnskategori, dvs. kvinnelig kjønn, kongestiv hjertesvikthistorie, hypertensjonshistorie, hjerneslag/TIA/tromboembolismehistorie, karsykdomshistorie og diabetes mellitus historie). Total CHA2DS2-VASc-score varierte fra 0-9 hvor 0= lav risiko og 9= høy risiko for hjerneslag.
Baseline (fra retrospektive data hentet i studien)
HAS-BLED Score at Baseline
Tidsramme: Baseline (from retrospective data retrieved in the study)
HAS-BLED scoring scale was used to estimate the risk of bleeding. HAS-BLED score was calculated based on 9 risk factors (hypertension, renal disease, liver disease, stroke history, prior major bleeding or predisposition to bleeding, labile international normalized ratio (INR), age >65 years, medication usage predisposing to bleeding and alcohol use). Total HAS-BLED score ranged from 0 to 9 where 0 = low risk and >=3 = high risk of bleed.
Baseline (from retrospective data retrieved in the study)
CHA2-DS2-VASc Score at Month 6
Tidsramme: Month 6 (from retrospective data retrieved in the study)
CHA2DS2-VASc scoring scale was used to estimate the risk of stroke and systemic emboli in participants with NVAF. CHA2DS2-VASc score was calculated based on 8 risk factors (age 65-74 years, age >=75 years, sex category i.e. female sex, congestive heart failure history, hypertension history, stroke/TIA/thromboembolism history, vascular disease history and diabetes mellitus history). Total CHA2DS2-VASc score ranged from 0-9 where 0= low risk and 9= high risk of stroke.
Month 6 (from retrospective data retrieved in the study)
HAS-BLED Score at Month 6
Tidsramme: Month 6 (from retrospective data retrieved in the study)
HAS-BLED scoring scale was used to estimate the risk of bleeding. HAS-BLED score was calculated based on 9 risk factors (hypertension, renal disease, liver disease, stroke history, prior major bleeding or predisposition to bleeding, labile international normalized ratio (INR), age >65 years, medication usage predisposing to bleeding and alcohol use). Total HAS-BLED score ranged from 0 to 9 where 0 = low risk and >=3 = high risk of bleed.

Up to first 6 months of treatment (from retrospective data retrieved in the study)
Cost of Outpatient Visits During First 6 Months of Treatment
Tidsramme: Opp til de første 6 månedene med behandling (fra retrospektive data hentet i studien)
Kostnader for polikliniske besøk ble beregnet for de første 6 månedene av behandlingen som antall besøk multiplisert med kostnadene for besøket (450,0 tsjekkiske koruna [CZK] per besøk). Kostnadene ble beregnet ut fra antall polikliniske besøk under behandlingen.

Percentage of Participants Categorized According to Number of International Normalized Ratios (INR) Measurements During First 6 Months of Treatment
Tidsramme: Opp til de første 6 månedene med behandling (fra retrospektive data hentet i studien)
INR was defined as the ratio of the participant's prothrombin time and the normal mean prothrombin time. Prothrombin time defined as a time taken by the blood to clot in participants receiving oral anticoagulant medication. In this outcome measure, percentage of participants were categorized according to number of INR measurements included zero (0), 1 to 9, 10 to 19 and greater than or equal to (>=) 20.
Opp til de første 6 månedene med behandling (fra retrospektive data hentet i studien)
Cost of INR Measurements During First 6 Months of Treatment
Tidsramme: Up to first 6 months of treatment (from retrospective data retrieved in the study)
INR was defined as the ratio of the participant's prothrombin time and the normal mean prothrombin time. Prothrombin time defined as a time taken by the blood to clot in participants receiving oral anticoagulant medication. Costs related to INR measurements, were calculated for the period of 6 months as the number of INR measurements multiplied by the cost of the INR measurement (213.0 CZK per measurement). Costs were based on the expenditure of total number of INR measurements during first 6-month treatment.
