RecruitingClinical trialFalls Validation StudyEach year, one in three adults over the age of 65 has a fall. These falls lead to half a million Canadian emergency department patient visits annually and falls in older adults account for more than 3% of all emergency department visits. A rapid, simple bedside test (known as a decision rule) to guide emergency physicians on when older adults should have a brain scan to diagnose traumatic brain bleeding was created. This decision rule will be checked to see if it works well in guiding who needs a brain scan.
