Primary Outcome Measures:
  • Percentage of Patients With Major Bleeding Events (MBE) [ Time Frame: From first intake (day of surgery) until 24 hours after last intake (planned: knee replacement: Day 10 after surgery, hip replacement: Day 28-35 after surgery) of Pradaxa ] [ Designated as safety issue: Yes ]
    Major bleeding events were defined according to the modified McMaster criteria, and were classified by the investigator as Major bleeding event or Any bleeding event. The criteria for MBE's were: fatal; clinically overt associated with loss of haemoglobin >=20g/L in excess of what was expected; clinically overt leading to the transfusion of >=2 units packed cells or whole blood in excess of what was expected; symptomatic retroperitoneal, intracranial, intraocular or intraspinal; requiring treatment cessation; leading to re-operation

  • Percentage of Patients With Symptomatic Venous Thromboembolic Events (sVTE) and All Cause Mortality [ Time Frame: From first intake (day of surgery) until 24 hours after last intake (planned: knee replacement: Day 10 after surgery, hip replacement: Day 28-35 after surgery) of Pradaxa ] [ Designated as safety issue: No ]
    The co-primary efficacy variable sVTE was defined as the composite of documented symptomatic proximal and distal deep vein thrombosis (DVT) and documented symptomatic non-fatal pulmonary embolism (PE) and All Cause Mortality.


Secondary Outcome Measures:
  • Documented Symptomatic Proximal DVT, Documented Symptomatic Distal DVT, Documented Symptomatic Nonfatal Pulmonary Embolism and All-cause Mortality [ Time Frame: From first intake (day of surgery) until 24 hours after last intake (planned: knee replacement: Day 10 after surgery, hip replacement: Day 28-35 after surgery) of Pradaxa ] [ Designated as safety issue: No ]
    Percentage of participant with documented symptomatic proximal DVT (deep vein thrombosis), documented symptomatic distal DVT, documented symptomatic nonfatal pulmonary embolism and all-cause mortality

  • Percentage of Patients With Major Extra-surgical Site Bleedings [ Time Frame: From first intake (day of surgery) until 24 hours after last intake (planned: knee replacement: Day 10 after surgery, hip replacement: Day 28-35 after surgery) of Pradaxa ] [ Designated as safety issue: Yes ]
    Percentage of Patients With Major Extra-surgical Site Bleedings

  • Volume of Wound Drainage (Post-operative) [ Time Frame: From first intake (day of surgery) until 24 hours after last intake (planned: knee replacement: Day 10 after surgery, hip replacement: Day 28-35 after surgery) of Pradaxa ] [ Designated as safety issue: Yes ]
    Volume of Wound Drainage after surgery
