Legislation has been enacted in some countries to mandate helmet use by cyclists, however the issue remains controversial with opponents arguing that this may inhibit people from bicycle(More)
OBJECTIVE Medication errors are a common cause of iatrogenic morbidity and mortality. The incidence of medication errors in pediatric emergency departments (EDs) has not been described. The objective of this study was to describe the incidence and type of drug errors in a pediatric ED and determine factors associated with risk of errors. METHODS A(More)
OBJECTIVES Patients returning to the emergency department (ED) within 72 hours of their visit may contribute to crowding and might indicate failure to give a proper assessment, treatment, or follow-up instructions.

The primary purpose of this study was to determine the fitness variables with the highest capability for predicting hockey playing potential at the elite level as determined by entry draft selection order. We also examined the differences associated with the predictive abilities of the test components among playing positions. The secondary purpose of this(More)
BACKGROUND The burden of childhood injury is often described using vital statistics for mortality and hospital admissions as a measure of morbidity. Hospital admissions, however, reflect the process of care and do not directly measure children's functional disability. The purpose of this study was to determine the influence of mechanism of injury on the(More)

Cardiac rehabilitation (CR) is a chronic disease management program designed to enhance and maintain cardiovascular health, and geographic barriers to utilization are often cited. The purpose of this study was to empirically test the drive time(More)
