An Observational Cross-sectional Study Evaluating the Use of Re-sources and the Sociodemographic and Clinical Characteristics of Patients Diagnosed With NVAF With a Risk of Stroke or Systemic Embolism on Anticoagulant Therapy and Treated in Primary Care Centers

This is a retrospective observational study to describe the sociodemographic and clinical characteristics of patients diagnosed with non-valvular atrial fibrillation (NVAF) at risk of stroke or systemic embolism, who at least three months ago changed their anticoagulant therapy, due to any clinical situation, and are currently on treatment with a direct oral anticoagulant (DOAC)

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients at risk of stroke or systemic embolism on anticoagulant therapy, who have changed their therapeutic regimen according to their doctor's decision, due to any clinical situation and based on routine clinical practice, and who at the time of enrolment in the study have been receiving treatment with a DOAC for at least three months

Description

Inclusion Criteria:

  • Patients ≥18 years of age diagnosed with non-valvular atrial fibrillation with a risk of stroke or systemic embolism treated in primary care centres.
  • Patients on regular treatment with anticoagulants who have changed their therapeutic regimen due to any clinical situation and have been on treatment with a direct oral anticoagulant for at least three months before being recruited (date of signing the in-formed consent).
  • Patients whose first direct oral anticoagulant prescription is written by the specialist (cardiologist, haematologist, internist, etc.) and who are followed in primary care.
  • Patients who have given their informed consent in writing.

Exclusion Criteria:

  • Patients who changed their anticoagulant therapy within a period of less than three months before signing the informed consent.
  • Patients with cognitive impairment preventing them from understanding what is written in the patient information sheet or the informed consent, or from per-forming the self-administered questionnaires.
  • Patients who started anticoagulant therapy for non-valvular atrial fibrillation with a direct oral anticoagulant .

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures.
