Study summary

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.

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

What researchers measure

Primary outcomes

  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.

    Time frame: One year

Secondary outcomes

  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.

    Time frame: One year

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 4, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
