Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Punteggio CHA2-DS2-VASc al basale
Lasso di tempo: Basale (da dati retrospettivi recuperati nello studio)
La scala di punteggio CHA2DS2-VASc è stata utilizzata per stimare il rischio di ictus ed emboli sistemici nei partecipanti con NVAF. Il punteggio CHA2DS2-VASc è stato calcolato sulla base di 8 fattori di rischio (età 65-74 anni, età >=75 anni, categoria di sesso, ovvero sesso femminile, storia di insufficienza cardiaca congestizia, storia di ipertensione, storia di ictus/TIA/tromboembolia, storia di malattie vascolari e anamnesi di diabete mellito). Il punteggio totale CHA2DS2-VASc variava da 0 a 9 dove 0 = basso rischio e 9 = alto rischio di ictus.
Basale (da dati retrospettivi recuperati nello studio)
HAS-BLED Score at Baseline
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: Fino ai primi 6 mesi di trattamento (dai dati retrospettivi recuperati nello studio)
I costi delle visite ambulatoriali sono stati calcolati per i primi 6 mesi di trattamento come numero di visite moltiplicato per il costo della visita (450,0 corona ceca [CZK] per visita). I costi sono stati calcolati in base al numero di visite ambulatoriali durante il trattamento.
Fino ai primi 6 mesi di trattamento (dai dati retrospettivi recuperati nello studio)
Percentage of Participants Categorized According to Number of International Normalized Ratios (INR) Measurements During First 6 Months of Treatment
Lasso di tempo: Fino ai primi 6 mesi di trattamento (dai dati retrospettivi recuperati nello studio)
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.
Fino ai primi 6 mesi di trattamento (dai dati retrospettivi recuperati nello studio)
Cost of INR Measurements During First 6 Months of Treatment
Lasso di tempo: 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)
