Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Score CHA2-DS2-VASc au départ
Délai: Ligne de base (à partir de données rétrospectives récupérées dans l'étude)
L'échelle de notation CHA2DS2-VASc a été utilisée pour estimer le risque d'AVC et d'emboles systémiques chez les participants atteints de NVAF. Le score CHA2DS2-VASc a été calculé sur la base de 8 facteurs de risque (âge 65-74 ans, âge >=75 ans, catégorie de sexe, c'est-à-dire sexe féminin, antécédents d'insuffisance cardiaque congestive, antécédents d'hypertension, antécédents d'accident vasculaire cérébral/AIT/thromboembolie, antécédents de maladie vasculaire et antécédents de diabète sucré). Le score CHA2DS2-VASc total variait de 0 à 9, où 0 = faible risque et 9 = risque élevé d'AVC.
Ligne de base (à partir de données rétrospectives récupérées dans l'étude)
HAS-BLED Score at Baseline
Délai: 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
Délai: 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
Délai: 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
Délai: Jusqu'aux 6 premiers mois de traitement (d'après les données rétrospectives récupérées dans l'étude)
Les coûts des visites ambulatoires ont été calculés pour les 6 premiers mois de traitement comme le nombre de visites multiplié par le coût de la visite (450,0 couronne tchèque [CZK] par visite). Les coûts ont été calculés en fonction du nombre de visites ambulatoires pendant le traitement.
Jusqu'aux 6 premiers mois de traitement (d'après les données rétrospectives récupérées dans l'étude)
Percentage of Participants Categorized According to Number of International Normalized Ratios (INR) Measurements During First 6 Months of Treatment
Délai: Jusqu'aux 6 premiers mois de traitement (d'après les données rétrospectives récupérées dans l'étude)
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.
Jusqu'aux 6 premiers mois de traitement (d'après les données rétrospectives récupérées dans l'étude)
Cost of INR Measurements During First 6 Months of Treatment
Délai: 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.
