Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
CHA2-DS2-VASc Score at Baseline
Zeitfenster: Baseline (aus retrospektiven Daten, die in der Studie abgerufen wurden)
Die CHA2DS2-VASc-Bewertungsskala wurde verwendet, um das Risiko für Schlaganfälle und systemische Embolien bei Teilnehmern mit NVAF abzuschätzen. Der CHA2DS2-VASc-Score wurde auf der Grundlage von 8 Risikofaktoren berechnet (Alter 65-74 Jahre, Alter >=75 Jahre, Geschlechtskategorie, d. h. weibliches Geschlecht, Herzinsuffizienz in der Vorgeschichte, Bluthochdruck in der Vorgeschichte, Schlaganfall/TIA/Thromboembolie in der Vorgeschichte, Gefäßerkrankung in der Vorgeschichte und Diabetes mellitus in der Anamnese). Der Gesamt-CHA2DS2-VASc-Score reichte von 0-9, wobei 0 = geringes Schlaganfallrisiko und 9 = hohes Schlaganfallrisiko bedeutet.
Baseline (aus retrospektiven Daten, die in der Studie abgerufen wurden)
HAS-BLED Score at Baseline
Zeitfenster: 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
Zeitfenster: 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
Zeitfenster: 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.

Cost of Outpatient Visits During First 6 Months of Treatment
Zeitfenster: Bis zu den ersten 6 Behandlungsmonaten (aus retrospektiven Daten aus der Studie)
Die Kosten für ambulante Besuche wurden für die ersten 6 Behandlungsmonate berechnet als die Anzahl der Besuche multipliziert mit den Kosten des Besuchs (450,0 Tschechische Krone [CZK] pro Besuch). Die Kosten wurden basierend auf der Anzahl der ambulanten Besuche während der Behandlung berechnet.
Bis zu den ersten 6 Behandlungsmonaten (aus retrospektiven Daten aus der Studie)
Percentage of Participants Categorized According to Number of International Normalized Ratios (INR) Measurements During First 6 Months of Treatment
Zeitfenster: Bis zu den ersten 6 Behandlungsmonaten (aus retrospektiven Daten aus der Studie)
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.
Bis zu den ersten 6 Behandlungsmonaten (aus retrospektiven Daten aus der Studie)
Cost of INR Measurements During First 6 Months of Treatment
Zeitfenster: 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.
Up to first 6 months of treatment (from retrospective data retrieved in the study)
