Medical Need of OAC Reversal

October 31, 2018 updated by: Boehringer Ingelheim

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

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.

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.

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

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.

Description

Inclusion Criteria:

->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

Exclusion Criteria:

  • Patients receiving two or more oral anti-coagulants at the same time at index date
  • Patients with prescriptions of index treatment in the 6 months prior to index date
  • Patients without enrolment period of at least six month in the database

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Number of Patients With Emergency Surgery and Major Bleeding Due to Fracture or Trauma.
Time Frame: One year
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.
One year

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.
Outcome Measure
Measure Description
Time Frame
The Number of Patients With Cardiac Tamponade and Pericardiocentesis.
Time Frame: One year
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.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 15, 2017

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
