  • Adult, Older adult

Study population: Any patients with atrial fibrillation contained in the Medical Data Vision (MDV) database which is a Japanese, nationwide claims data containing approximately 16 million patients cumulatively. The data cut is between March 2011 to June 2016, and the patients in the MDV database are those who have visited DPC hospitals (diagnostic procedure combination, a lump-sum payment system based on disease diagnosis to be treated similar to Medicare/Medicaid in the USA) hospitals which provide acute in-patient, as well as outpatient care.

Who may be able to join

  • ->18 year old non-valvular atrial fibrillation (NVAF) patients
  • Prescribed dabigatran, rivaroxaban, apixaban, edoxaban or warfarin
  • Patients with confirmed date of initiation of OACs
  • Patients with a minimum of 6 months of enrolment data prior to index date
  • Has an index date between 14th of March 2011 to 30 June, 2016

Who cannot join

  • Patients receiving two or more oral anti-coagulants at the same time at index date

About this study

Official title: Medical Need of Oral Anti-coagulant Reversal in Japan: Epidemiological Assessment of Head Trauma, Fracture, and Emergency Surgery Using Large Scale Claims Database (Please Note That This Study Contains no Patients Treated With Idarucizumab Although the Study Number Begins With 1321; the Study Contains Only Patients Treated With OACs, Namely Warfarin, Dabigatran, Edoxaban, Apixaban, Rivaroxaban, Edoxaban)

This is a retrospective, observational, claims cohort study to assess, for adult patients initiating an oral anticoagulant for NVAF

Read the detailed description

This is a retrospective, observational, claims cohort study to assess, for adult patients initiating an oral anticoagulant for NVAF, the incidence rates of emergency surgery, major bleeding due to trauma, and major bleeding due to fracture, overall and stratified by age (<64, 65-74, >75). The secondary objective is to estimate the overall and age stratified incidence of cardiac tamponade and peri-cardiocentesis.

Being tested
warfarin, dabigatran, Apixaban, Edoxaban, Rivaroxaban

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Number of Patients With Emergency Surgery and Major Bleeding Due to Fracture or Trauma.

    The number of patients with emergency surgery and major bleeding due to fracture or trauma. Where emergency surgery defined as any surgical procedure (International Classification of Diseases (ICD) 10 code K000-879) performed on the same day as hospital admission with additional claims, major bleeding due to fracture is any bleeding associated with hospitalization or blood transfusion (ICD10 code E83.111) accompanied by any fracture, and major bleeding due to trauma is any bleeding associated with hospitalization or blood transfusion (ICD10 code E83.111) accompanied by any trauma.

    Measured: One year

Secondary outcomes (1)
  1. The Number of Patients With Cardiac Tamponade and Pericardiocentesis.

    The number of patients with cardiac tamponade and pericardiocentesis. Cardiac tamponade diagnosis (ICD 10 code 4200001) on the same or next day as catheter ablation or percutaneous coronary intervention (PCI), Pericardiocentesis (Medical Data Vision (MDV) procedure code 140010510) on the same or next day as catheter ablation or PCI.

    Measured: One year
