Primary Outcome Measures:
  • Percentage of Patients With Major Bleeding Events (MBE) During Treatment Period [ 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).


Secondary Outcome Measures:
  • 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 ]
  • Volume of Wound Drainage (Post-operative) [ Time Frame: From end of surgery (before first dosing) 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 ]
    Total volume of wound drainage is calculated as sum of volume drainage from end of surgery until first dose of Pradaxa plus volume drainage from first dose of Pradaxa and onwards.

  • Percentage of Patients With Single Components of Composite of 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 ]
