This outcome measure describes the incidence of stroke (hemorrhagic and ischemic) for dabigatran and warfarin in the primary analysis. Ischemic stroke includes: Occlusion and stenosis of precerebral arteries with cerebral infarction, Occlusion of cerebral arteries with cerebral infarction and Acute, but ill-defined, cerebrovascular disease but excludes above diagnosis if hospitalization lasted less than 48 hours and was accompanied by carotid endarterectomy. Hemorrhagic stroke includes: Subarachnoid hemorrhage (SAH) and Intracerebral hemorrhage (ICH) but excludes previous listed diagnoses if "traumatic brain injury" or "rehabilitation care" is present. Study outcomes for this analysis were identified using either the admitting diagnoses or on any of the service lines associated with an inpatient hospitalization.
Stroke (Post-hoc Analysis)
Time frame: From 1 October 2010 to 30 April 2013 identified with index date (first prescription of dabigatran or warfarin) plus a follow-up period of 12 months (up to 42 months)
This outcome measure describes the incidence of stroke (hemorrhagic and ischemic) for dabigatran and warfarin in the post-hoc analysis. A post-hoc analysis was conducted that measured outcomes using an algorithm to define the principal diagnosis. The principal diagnosis was defined as the primary diagnosis on the first room and board charge record within a hospital admission. This method results in identification of a single outcome for a hospitalization.
Major Bleeding (Primary Analysis)
Time frame: From 1 October 2010 to 30 April 2013 identified with index date (first prescription of dabigatran or warfarin) plus a follow-up period of 12 months (up to 42 months)
This outcome measure describes the incidence of major bleeding (hemorrhagic stroke, major intracranial bleeding and major extracranial bleeding) for dabigatran and warfarin in the primary analysis. Major Intracranial Bleeding includes subarachnoid hemorrhage, intracerebral hemorrhage, other and unspecified intracranial hemorrhage, subarachnoid hemorrhage following injury without mention of open intracranial wound, subdural hemorrhage following injury without mention of open intracranial wound, extradural hemorrhage following injury without mention of open intracranial wound, other and unspecified intracranial hemorrhage following injury without mention of open intracranial wound but excludes these codes if major trauma was present. Major extracranial bleeding includes major gastrointestinal (GI) bleeding, major urogenital bleeding and major other bleeding. Either the admitting diagnoses or on any of the service lines associated with an inpatient hospitalization were used.

What does the primary outcome measure?
Stroke (Primary Analysis) (time frame: From 1 October 2010 to 30 April 2013 identified with index date (first prescription of dabigatran or warfarin) plus a follow-up period of 12 months (up to 42 months)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jun 2017.
