Intervention

Drug:
• Rivaroxoban (Xarelto, Bay59-7939)
The treatment of deep vein thrombosis (DVT) or pulmonary embolism (PE), and prevention of recurrent DVT and PE in adult patients (15 mg rivaroxaban twice daily [bid] for 3 weeks, then 15 mg or 20 mg once daily [od], tablets). The prevention of stroke and systemic embolism in adult patients with non-valvular atrial fibrillation (stroke prevention in atrial fibrillation [SPAF]) with one or more risk factors (20 mg rivaroxaban [od], tablets). The prevention of venous thromboembolism (VTE) in adult patients undergoing elective hip or knee replacement surgery (recommended dose: 10 mg rivaroxaban [od] tablets for 35 days following hip replacement surgery and 14 days following knee replacement surgery). Co-administered with acetylsalicylic acid (ASA) alone or with ASA plus clopidogrel or ticlopidine, for the prevention of atherothrombotic events in adult patients after an acute coronary syndrome (ACS) with elevated cardiac biomarkers (recommended dose 2.5 mg rivaroxaban tablets [bid]).
• Standard of care
For DVT/PE treatment and SPAF, standard of care is treatment with the most widely used vitamin K antagonist, phenprocoumon, and for the secondary prevention of ACS, standard of care is antiplatelet drug(s) such as low-dose acetylsalicylic acid, clopidogrel, dipyridamole, prasugrel, ticlopidine and ticagrelor.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Descriptive analysis of demographic and clinical characteristics of patients who are prescribed oral rivaroxaban for the first time in comparison with those who are prescribed standard of care for the first time	Age and sex distribution at index date Proportion of patients defined as naïve, non-naïve, recent switchers and distant switchers Type and estimated duration of other anticoagulant use among the non-naïve group and for all patients Number of pregnancies and pregnancy outcomes' Use of specific prescribed medications confirming ACS indication Use of other prescribed medications Renal disease based on in- and outpatient diagnoses Hospital admissions for bleeding Healthcare utilization (e.g. number of hospital admissions). Smoking status Body mass index (BMI)	up to 8 years
Primary	Characteristics of rivaroxaban use in comparison with standard of care	Estimated dose of index drug at index date and estimated duration of treatment Where available, the diagnosis associated with the prescribing of the index drug (where not available, estimated dose and duration of index drug will be used as a proxy for the associated diagnosis among rivaroxaban users) Dispensed amount (can be used to estimate duration of treatment)	up to 8 years
Primary	Safety: occurrence of intracranial haemorrhage leading to hospitalization among users of rivaroxaban in comparison with individuals receiving current standard of care	Cases of intracranial haemorrhage will be identified in patients admitted to the hospital that meet the criteria for one of the three following categories: Incident cases of intracerebral haemorrhage Incident cases of subarachnoid haemorrhage incident cases of epidural, dural, subdural and arachnoid haemorrhage Potential cases will be identified by hospital discharge diagnoses	up to 8 years
Primary	Safety: occurrence of gastrointestinal bleeding leading to hospitalization among users of rivaroxaban in comparison with individuals receiving current standard of care	A patient will have to meet the following criteria to be considered a case of gastrointestinal bleeding: The specific site of bleeding originating in the upper or lower gastrointestinal tract or, more specifically, in the oesophagus, stomach, duodenum, jejunum, ileum, colon or rectum.; For upper gastrointestinal bleeding, the lesion type being erosion, gastritis, duodenitis or peptic (gastric or duodenal) ulcer.; The lesion type being NOT related to cancer. Cases will be identified by hospital discharge diagnoses (ICD-9-CM).	up to 8 years
Primary	Safety: occurrence urogenital bleeding leading to hospitalization among users of rivaroxaban in comparison with individuals receiving current standard of care	A patient will have to be admitted to the hospital for urogenital bleeding, i.e. the specific site of bleeding originating in the urogenital tract.; Cases will be identified by hospital discharge diagnoses (ICD-9-CM).	up to 8 years
Secondary	Safety: occurrence of bleeding events leading to hospitalization not specified as primary safety outcomes ("other bleeding") in individuals receiving rivaroxaban, in comparison with those receiving current standard of care	A patient will have to meet the following criteria to be considered a case of "other bleeding": Admitted to hospital with a bleeding event occurring before hospitalization (i.e. excluding inhospital bleeding events).; Cases will be identified by hospital discharge diagnoses (ICD-9-CM).	up to 8 years
Secondary	Safety: occurrence of non-infective liver disease leading to hospitalization in individuals receiving rivaroxaban in comparison with those receiving current standard of care	A patient will have to meet both of the following criteria to be considered a case of non-infective liver disease: The patient having been admitted to hospital with acute liver injury. Free of cancer, other liver disease (including infectious hepatitis, chronic liver disease etc.), gallbladder or pancreatic disease and alcoholism.	up to 8 years
