A Study of Participants With Non-Valvular Atrial Fibrillation (NVAF) Treated or Untreated With Oral Anticoagulant in the National Cerebral and Cardiovascular Center (NCVC) in Japan

March 3, 2022 updated by: Bristol-Myers Squibb

Retrospective Medical Chart Review Study for Non-valvular Atrial Fibrillation Patients Treated or Untreated With Oral Anticoagulant in the National Cerebral and Cardiovascular Center (NCVC) in Japan

The purpose of this observational study is to understand real-world oral anticoagulants (OAC) (warfarin, apixaban, dabigatran, edoxaban and rivaroxaban) usage for non-valvular atrial fibrillation (NVAF) patients.

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

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Sampling Method

Non-Probability Sample

Study Population

The study population will consist of an estimated 12,000 Non-valvular atrial fibrillation (NVAF) participants' medical charts that will fulfill the study eligibility criteria.

Description

Inclusion Criteria:

• Participants received medical treatment for NVAF between 10-Jan-2012 and 31-Aug-2020.

Exclusion Criteria:

  • Had no data of serum creatinine in the participant's medical records
  • Had no data of body weight in the participant's medical records
  • Were given oral anticoagulant (OAC) for treatment of diseases other than atrial fibrillation (AF)

Other protocol-defined inclusion/exclusion criteria apply.

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. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
