Atrial Fibrillation
Conditions
Brief summary
This is a retrospective, observational, claims cohort study to assess, for adult patients initiating an oral anticoagulant for NVAF
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The Number of Patients With Emergency Surgery and Major Bleeding Due to Fracture or Trauma. | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The Number of Patients With Cardiac Tamponade and Pericardiocentesis. | 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. |

| Patients Prescribed With Non-warfarin Oral Anti Coagulants Patients prescribed with Non-warfarin Oral Anti Coagulants (NOACs) (dabigatran, rivaroxaban, apixaban, edoxaban) or warfarin were grouped as a single exposure group and analysed as a whole. On treatment duration was expressed in patient year for the follow-up duration to calculate the incidence of various clinical events during the on-treatment duration. | 53,969 |

Outcome results
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
Population: Results are based on the number of patients meeting the inclusion and exclusion criteria.
