Concept: Atrial Fibrillation

Introduction

This concept defines atrial fibrillation as it was used in the Care of Manitobans Living with Chronic Kidney Disease deliverable by Chartier et al. (2015). This includes the age groups applied, the data sources for this definition, and the code values and conditions that are used to identify atrial fibrillation. A brief description of the use of this condition and the key findings from this research are also included.

Technical Definition of Atrial Fibrillation

The technical definition of atrial fibrillation used in Chartier et al. (2015) is as follows:


• Age Groups:
  
  • Adults: 18 years and older
  
  
• Data Sources:
  
  • Hospital Abstracts data; and the
    
  • Medical Services (Physician Claims) data
  
  
• Code Values and Conditions: - defined as Manitoba residents with the following diagnoses codes and conditions in the three-years fiscal period 2009/10 - 2011/12:
  
  
  • one or more inpatient hospitalizations with diagnosis of atrial fibrillation (ICD-9-CM: 427, ICD-10-CA: I48); or
    
  • two or more physician claims with diagnoses for atrial fibrillation (prefix=7, ICD-9-CM: 427).

Methods and Findings

In the Care of Manitobans Living with Chronic Kidney Disease deliverable by Chartier et al. (2015) they investigated the prevalence and relative risk of atrial fibrillation as a comorbidity to end stage kidney disease (ESKD) and chronic kidney disease (CKD).

For more information on prevalence and relative risk, see:
