Assessment of Adherence to New Oral anTicoagulants in Atrial Fibrillation patiEnts Within the Outpatient registrY Profile. Prospective Observational Study. ANTEY Study

A prospective non-interventional single-centre study aimed to evaluate actual adherence of AF patients using the validated adherence Scale.

Primary Study Objective(s) Primary study objective The aim of the present study is to assess adherence to therapy and factors associated with adherence in patients with CV disease complicated by non-valvular atrial fibrillation requiring OAC treatment within the outpatient registry PROFILE (prospective, observational study).

  1. Data collection in patients with non-valvular atrial fibrillation requiring OAC treatment included in the registry
  2. Evaluation of actual patient adherence to OACs

Secondary Study Objective(s)

  1. Evaluation of potential patient adherence to OACs
  2. Determination of the most significant factors associated with adherence to OACs in patients with non-valvular AF
  3. Validation of new original 5-item Questionnaire
  4. Evaluation of doctor's adherence to OAC prescription according to Guidelines (ESC). Management of atrial fibrillation,2016)

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Proportions of Adherent, Partially Adherent, Partially Non-adherent and Completely Non-adherent Patients (NSEPh During V1)
Periodo de tiempo: 6 months

The study consisted of two visits half a year apart (V0, V1) and a phone contact (PC) one year after V0. During V0 all patients were recommended to start therapy with one of the NOACs.

Adherence to therapy was assessed during V1 with the use of the original questionnaire - National society of evidence-based pharmacotherapy (NSEPh) adherence scale.

Periodo de tiempo: 1 year

The study consisted of two visits half a year apart (V0, V1) and a phone contact (PC) one year after V0. During V0 all patients were recommended to start therapy with one of the NOACs.

Adherence to therapy was assessed during phone contact with the use of the original questionnaire - National society of evidence-based pharmacotherapy (NSEPh) adherence scale.

Out of 201 participants of the study 4 patients died and 197 patients completed the study.

Medida de resultado
Medida Descripción
Periodo de tiempo
Proportion of Potentially Adherent Patients
Periodo de tiempo: Total - 1 year (two timepoints - 6 months (V1) and 1 year (PC)
Specifically designed 5-item questionnaire was used for assessment of potential adherence to OACs. According to results patients were divided into groups: completely adherent, partially adherent, completely non-adherent to OACs.
Total - 1 year (two timepoints - 6 months (V1) and 1 year (PC)
Proportion of OACs Prescribed by Doctors According to Guidelines
Periodo de tiempo: Total - 1 year (two timepoints - 6 months (V1) and 1 year (PC)

Prescription of OACs according to guidelines was considered "positive" if it matched the key points of 2016 ESC Guidelines for the management of atrial fibrillation.

  1. Oral anticoagulation therapy to prevent thromboembolism is recommended for all male AF patients with a CHA2DS2-VASc score of 2 or more.
  2. Oral anticoagulation therapy to prevent thromboembolism is recommended in all female AF patients with a CHA2DS2-VASc score of 3 or more.
  3. Antiplatelet monotherapy is not recommended for stroke prevention in AF patients, regardless of stroke risk.
  4. NOACs (apixaban, dabigatran, edoxaban, and rivaroxaban) are not recommended in patients with mechanical heart valves (Level of evidence B) or moderate-to-severe mitral stenosis (Level of evidence C).
  5. In male or female AF patients without additional stroke risk factors, anticoagulant or antiplatelet therapy is not recommended for stroke prevention.
Total - 1 year (two timepoints - 6 months (V1) and 1 year (PC)
The Main Reasons for Refusing to Start NOAC Therapy
Periodo de tiempo: Total - 1 year (two timepoints - 6 months (V1) and 1 year (PC)
The study consisted of two visits half a year apart (V0, V1) and a phone contact (PC) one year after V0. During V0 all patients were recommended to start therapy with one of the NOACs. Patients refusing to start NOAC treatmet were asked about the reasons to refuse NOAC treatment.
Total - 1 year (two timepoints - 6 months (V1) and 1 year (PC)
Reasons for Stopping Oral Anticoagulants (Data From Visit 1)
Periodo de tiempo: Total - 1 year (two timepoints - 6 months (V1) and 1 year (PC))
The study consisted of two visits half a year apart (V0, V1) and phone contact (PC) one year after V0. During V0 all patients were recommended to start therapy with one of the NOACs. Patients who stopped or didn't start NOAC treatment were asked about the reasons for non-adherence to anticoagulants use during visit 1 (6 months) and at PC (1 year).
Total - 1 year (two timepoints - 6 months (V1) and 1 year (PC))
Reasons for Stopping Oral Anticoagulants (Data From the Phone Contact)
Periodo de tiempo: Total - 1 year (two timepoints - 6 months (V1) and 1 year (PC)
The study consisted of two visits half a year apart (V0, V1) and a phone contact (PC) one year after V0. During V0 all patients were recommended to start therapy with one of the NOACs. Patients who stopped NOAC treatmet were asked about the reasons for stopping oral anticoagulants (NOAC and warfarin) use during the phone contact.
