ListOutcomeTime frameDescription
PrimaryPercentage of Patients With ObesityUp to 12 months
Percentage of patients with obesity; where obesity is defined as "obese, not-obese based on note of obesity or recorded body mass index (BMI) \> 30 in the electronic medical records (EMR)". The results are provided before and after propensity score (PS) matching. Before PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR whose data were available; After PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR, 1:1 propensity score matched, whose data were available.
PrimaryPercentage of Patients SmokingUp to 12 months
Percentage of patients with current/past smoking in the electronic medical records (EMR) are presented. The results are provided before and after propensity score (PS) matching. Before PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR whose data were available; After PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR, 1:1 propensity score matched, whose data were available.
PrimaryPercentage of Patients With Alcohol ConsumptionUp to 12 months
Percentage of patients with alcohol consumption in the electronic medical records (EMR) are presented. The patients with light to moderate, heavy and unknown quantity of alcohol consumption are considered. The results are provided before and after propensity score (PS) matching. Before PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR whose data were available; After PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR, 1:1 propensity score matched, whose data were available.
PrimaryPercentage of Patients With Abnormal Renal FunctionUp to 12 months
Percentage of patients with abnormal renal function; defined as "Any note of: Dialysis, renal transplant Serum Creatinine \>1.3 Milligrams per Deciliter (mg/dL) in the electronic medical records (EMR)". Response was considered to be truly absent if not recorded in the EMR. The results are provided before and after propensity score (PS) matching. Before PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR whose data were available; After PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR, 1:1 propensity score matched, whose data were available.
PrimaryPercentage of Patients With Bleeding History or PredispositionUp to 12 months
Percentage of patients with bleeding history or predisposition is presented, defined as any note of major bleeding requiring hospitalization or blood transfusion or causing a decrease in hemoglobin level of \> 2 gram per liter (g/L) in the electronic medical records (EMR). Response was considered to be truly absent if not recorded in the EMR. The results are provided before and after propensity score (PS) matching. Before PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR whose data were available; After PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR, 1:1 propensity score matched, whose data were available.
PrimaryEMR Characteristic: Renal Function - Glomerular Filtration Rate (GFR)Up to 12 months
EMR characteristic: Renal function - Glomerular Filtration Rate (GFR). Estimated GFR closest to index dispensing. The results are provided before and after propensity score (PS) matching. Before PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR whose data were available; After PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR, 1:1 propensity score matched, whose data were available.
PrimaryEMR Characteristic: Serum CreatinineUp to 12 months
EMR characteristic: Serum Creatinine closest to index dispensing. The results are provided before and after propensity score (PS) matching. Before PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR whose data were available; After PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR, 1:1 propensity score matched, whose data were available.
PrimaryPercentage of Patients With Abnormal Liver FunctionUp to 12 months
Percentage of patients with abnormal liver function; defined as "Any note of: Liver disease, cirrhosis, Active hepatitis C, Active hepatitis B, Active hepatitis A, aspartate transaminase/alanine transaminase (AST/ALT) \>3 times upper limit of normal in the electronic medical records (EMR). Absence of any note would be considered as absence of the disease". Response was considered to be truly absent if not recorded in the EMR. The results are provided before and after propensity score (PS) matching. Before PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR whose data were available; After PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR, 1:1 propensity score matched, whose data were available.
SecondaryEMR Characteristic: Duration of Atrial FibrillationUp to 12 months
EMR characteristic: Duration of atrial fibrillation (Years / months prior to initiation of Dabigatran / Warfarin). Duration is defined as number of months prior to index date for the earliest note. The results are provided before and after propensity score (PS) matching. Before PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR whose data were available; After PS matching: all patients meeting inclusion/exclusion criteria successfully linked to EMR, 1:1 propensity score matched, whose data were available.
SecondaryEMR Characteristic: History of Adherence: Non-adherent/AdherentUp to 12 monthsEMR characteristic: History of adherence: non-adherent/adherent.
